Abstract

A lock device is provided. The lock device includes a housing with a front opening at an end; a rotating hook disposed in the housing and being rotatable relative to the housing, the rotating hook including a front-end portion and a rear-end portion, the front-end portion at least partially protruding from the front opening, and the rear-end portion extending toward a direction opposite to the front-end portion; a driving device disposed in the housing and selectively moveable to change widths by which the front-end portion is opened respectively; and a lock body disposed in the housing, when the lock body is locked, the lock body restricting a movement of the driving device.

First claim

What is claimed is:

1. A lock device, comprising:
a housing with a front opening at an end;
at least two rotating hooks disposed in the housing and being rotatable relative to the housing along a plane parallel to an X-Y plane having a X-axis and a Y-axis, each of the rotating hook comprising a front-end portion and a rear-end portion, the front-end portion at least partially protruding from the front opening, and the rear-end portion extending toward a direction opposite to the front-end portion;
a driving device disposed in the housing and selectively moveable to change widths by which the front-end portions are opened respectively; and
a lock body disposed in the housing, when the lock body is locked, the lock body restricting a movement of the driving device,
wherein the driving device includes a driving portion being capable of moving along a Z-axis direction by different depths to be between the rear-end portions, respectively, wherein the width at the front-end portions of the rotating hooks is configured to change an amount which corresponds to the depth at which the driving portion is moved along the Z-axis direction, wherein, when the lock body is locked, the lock body is configured to restrict the movement of the driving portion along the Z-axis direction, the X axis, the Y axis, and the Z axis being orthogonal to each other.

2. The lock device according to claim 1 , wherein the driving device comprises:
a driving member, comprising:
a driving member top surface located on one side of the driving member;
a driving member bottom surface located on one side of the driving member opposite to the driving member top surface, the driving member bottom surface orienting toward the rotating hooks and having the driving portion, wherein the driving portion corresponds to a gap between the rear-end portions, and when the driving member is moved toward the rotating hook along the Z-axis direction, the driving portion is capable of extending into the gap between the rear-end portions to abut against the rear-end portions to cause the rear-end portions to be away from each other, thereby causing the front-end portions to be away from each other; and

a force applying member being rotatable relative to the housing along the plane parallel to the X-Y plane and comprising a force applying member top surface and a force applying member bottom surface located on opposite sides of the force applying member, the force applying member bottom surface orienting toward the driving member and having a force applying unit, wherein the force applying unit corresponds to the driving member top surface.

3. The lock device according to claim 2 , wherein the driving device further comprises an elastic device disposed between the driving member and an inner wall of the housing and providing an elastic force applied between the driving member and an inner wall of the housing along the Z-axis direction.

4. The lock device according to claim 2 , wherein the driving device member top surface comprises:
a guide ramp having a plurality of steps; and
a stop disposed at a position adjacent to a bottom surface of the guide ramp, wherein the driving member top surface has a top surface position between the bottom surface of the guide ramp and the stop.

5. The lock device according to claim 2 , wherein a braking element is disposed at an end of the lock body, when the lock body is locked, the braking element protruding toward the force applying member to be engaged with the force applying member to restrict a rotation of the force applying member, thereby restricting a movement of the driving device along the Z-axis direction.

6. The lock device according to claim 5 , wherein the braking element has a fixing hole, and a periphery of the force applying member has a plurality of fixing portions, when the lock body is locked, the braking element protruding toward the force applying member, so that at least one of the fixing portions is inserted into the fixing hole.

7. The lock device according to claim 1 , wherein the driving device comprises: a driving member comprising a driving member bottom surface orienting toward the rotating hooks and having a plurality of driving portions, wherein the driving member capable of being rotated to cause one of the driving portions to correspond to a gap between the rear-end portions, and when the driving member is moved toward the rotating hook along the Z-axis direction, the corresponding driving portion is capable of extending into the gap between the rear-end portions to abut against the rear-end portions to cause the rear-end portions to be away from each other, thereby causing the front-end portions to be away from each other.

8. The lock device according to claim 7 , wherein a displacement limiting member protrudes from a side wall of the lock body, and a plurality of guide grooves are disposed on a side wall of the driving member, when the driving member is rotated to the displacement limiting member to correspond to one of the guide grooves, respectively, the force applying member moving downward from the Z axis to respectively cause the displacement limiting member to enter the corresponding guide groove, so that one of the driving portions extends between the rear-end portions.

9. The lock device according to claim 7 , wherein the driving device further comprises an elastic device disposed between the driving member and an inner wall of the housing and providing an elastic force along the Z-axis direction.
