Abstract

A lock of the present invention includes a housing, a rotating hook, a driving apparatus, and a lock body. An end of the housing includes a front-end opening. The front-end opening faces a same direction as an extending direction of an X-axis, and deviates from a center of a section parallel to a Y-Z plane of the end of the housing that includes the front-end opening, where the X-axis, a Y-axis, and a Z-axis are orthogonal. The rotating hook is arranged in the housing and is rotatable relative to the housing, and includes a front end and a rear end, where the front end at least partially extends out of the front-end opening, and the rear end extends in an opposite direction to the front end. The driving apparatus is arranged in the housing and is movable to change an opening width of the front end. The lock body is arranged in the housing, and when the lock body is locked, the lock body restricts movement of the driving apparatus.

First claim

What is claimed is:

1 . A lock, comprising:
a housing, wherein an end of the housing comprises a front-end opening facing a same direction as an extending direction of an X-axis, the front-end opening deviates from a center of a section parallel to a Y-Z plane of the end, and the X-axis, a Y-axis, and a Z-axis are orthogonal; a rotating hook, arranged in the housing and rotatable relative to the housing, and comprising a front end and a rear end, wherein the front end at least partially extends out of the front-end opening, and the rear end extends in an opposite direction to the front end; a driving apparatus, arranged in the housing, and movable to change an opening width of the front end; and a lock body, arranged in the housing, wherein when the lock body is locked, the lock body restricts movement of the driving apparatus; wherein the rear end is provided with a driving groove, and the driving apparatus comprises a driving portion extending into the driving groove along a Z-axis direction, when the lock body is unlocked, the driving portion is movable along the X-axis direction to rotate the rotating hook relative to the housing along a plane parallel to an X-Y plane to change the opening width of the front end, and when the lock body is locked, the lock body restricts the movement of the driving apparatus; wherein the driving apparatus comprises:
a force applying part, penetrating the housing, movable along a plane parallel to the Y-Z plane, and comprising a force applying portion arranged in the housing;
a first driving part, arranged in the housing, abutting against the force applying part, and movable along the X-axis direction;
a second driving part, arranged between the first driving part and the rotating hook in the housing, abutting against the first driving part, movable along the X-axis direction, and comprising the driving portion;
a first elastic apparatus, arranged at a side of the first driving part to provide first elastic force, so that the first driving part approaches the second driving part; and
a second elastic apparatus, arranged at a side of the second driving part to provide second elastic force, so that the second driving part is far away from the rotating hook, wherein a component of the first elastic force along the X-axis direction is larger than a component of the second elastic force along the X-axis direction, wherein
when the lock body is unlocked, the force applying part is movable towards an inside of the housing, pushes the first driving part to move along the X-axis direction to be away from the rotating hook to move the second driving part along the X-axis direction to be away from the rotating hook, and drives the driving portion to move along the X-axis direction to rotate the rotating hook relative to the housing along a plane parallel to the X-Y plane.

2 . The lock according to claim 1 , wherein the lock body comprises a locking piece, and when the lock body is locked, the locking piece is located on a path of the first driving part moving along the X-axis direction, to restrict the first driving part moving along the X-axis direction.

3 . The lock according to claim 2 , wherein the first driving part further comprises a guide slope abutting against the second driving part, the guide slope is provided with a plurality of steps, the plurality of steps have a segment difference in the X-axis direction, the first driving part is rotatable along the plane parallel to the Y-Z plane to make one of the plurality of steps abut against the second driving part and change a position of the second driving part in the X-axis direction, to drive the driving portion to move along the X-axis direction, make the rotating hook rotate relative to the housing along the plane parallel to the X-Y plane, and change the opening width of the front end.

4 . The lock according to claim 3 , further comprising a third driving part, arranged on another side of the first driving part relative to the second driving part, wherein
when the lock body is unlocked, the third driving part can be clamped with the first driving part and drives the first driving part to rotate along the plane parallel to the Y-Z plane; and when the lock body is locked, the locking piece is clamped with the third driving part to restrict the third driving part rotating along the plane parallel to the Y-Z plane.

5 . The lock according to claim 4 , wherein
the first driving part comprises a limiting pin arranged at an end of the first driving part adjacent to the third driving part; and the third driving part comprises a limiting part arranged at an end that is on a side surface of the third driving part and that is adjacent to the first driving part, and the third driving part is movable towards the first driving part to clamp the spacing part with the limiting pin.

6 . The lock according to claim 5 , wherein the third driving part comprises a limiting groove, arranged at a position outside the limiting part on the side surface of the third driving part along the X-axis direction; and when the lock body is locked, the locking piece extends into the limiting groove to restrict the third driving part rotating along the plane parallel to the Y-Z plane.

7 . A lock, comprising:
a housing, an end of the housing comprising a front-end opening; a rotating hook, arranged in the housing and rotatable relative to the housing, and comprising a front end and a rear end, wherein the front end at least partially extends out of the front-end opening, the rear end extends in an opposite direction to the front end, and the rear end is provided with a driving groove disposed inside; a driving apparatus, arranged in the housing and movable to change an opening width of the front end, wherein the driving apparatus comprises a driving portion extending into the driving groove along a Z-axis direction; and a lock body, arranged in the housing, wherein when the lock body is unlocked, the driving portion is movable along an X-axis direction to rotate the rotating hook relative to the housing along a plane parallel to an X-Y plane to change the opening width of the front end, and when the lock body is locked, the lock body restricts movement of the driving apparatus, wherein an X-axis, a Y-axis, and a Z-axis are orthogonal; wherein the front-end opening faces a same direction as an extending direction of the X-axis, and deviates from a center of a section parallel to a Y-Z plane of the end; wherein the driving apparatus comprises:
a force applying part, penetrating the housing, movable along a plane parallel to the Y-Z plane, and comprising a force applying portion arranged in the housing;
a first driving part, arranged in the housing, abutting against the force applying part, and movable along the X-axis direction;
a second driving part, arranged between the first driving part and the rotating hook in the housing, abutting against the first driving part, movable along the X-axis direction, and comprising the driving portion;
a first elastic apparatus, arranged at a side of the first driving part to provide first elastic force, so that the first driving part approaches the second driving part; and
a second elastic apparatus, arranged at a side of the second driving part to provide second elastic force, so that the second driving part is far away from the rotating hook, wherein a component of the first elastic force along the X-axis direction is larger than a component of the second elastic force along the X-axis direction, wherein
when the lock body is unlocked, the force applying part is movable towards an inside of the housing, pushes the first driving part to move along the X-axis direction to be away from the rotating hook to move the second driving part along the X-axis direct
