Abstract

The present invention relates to a lock device, comprising a housing including a lock hook mounted in the housing, the lock hook pivotally moves to and away from a lock hook locked position; a locking slider for locking the lock hook, the locking slider having a locking slider first end which abuts against an axial surface of the lock hook, the locking slider is reciprocatingly slideable in a first direction parallel to the lock hook pivoting plane following pivoting of the lock hook to move to or away from a locking slider locked position; a slider locking device for locking the locking slider, the slider locking device is reciprocating slideable in a second direction following the reciprocatingly sliding of the locking slider in the first direction, the second direction crosses the lock hook pivoting plane. The present invention further relates to an apparatus mounted with the lock device.

First claim

What is claimed is:

1. A lock device, comprising a housing including:
a lock hook mounted in the housing, the lock hook pivotally moves to and away from a lock hook locked position;
a locking slider for locking the lock hook, the locking slider having a locking slider first end which abuts against a radial surface of the lock hook, the locking slider is reciprocatingly slideable in a first direction normal to a direction of the lock hook pivoting axis following pivoting of the lock hook to move to or away from a locking slider locked position;
a slider locking device for locking the locking slider, the slider locking device is reciprocating slideable in a second direction following the reciprocatingly sliding of the locking slider in the first direction, the second direction crosses a lock hook pivoting plane,
wherein the locking slider first end has a first lock hook contacting surface and a second lock hook contacting surface; when the locking slider is located at the locking slider locked position, the first lock hook contacting surface abuts against the radial surface of the lock hook; as the locking slider slides away from the locking slider locked position, the first lock hook contacting surface gradually disengages from contacting the lock hook radial surface and the second lock hook contacting surface gradually contacts and abuts against the lock hook radial surface.

2. The lock device according to claim 1 , wherein:
the slider locking device having a slider locking device first end which abuts against a side surface of the locking slider;
a locking slider oblique surface inclined to the first direction is provided on the side surface of the locking slider, and a slider locking device oblique surface which is complementary with the locking slider oblique surface is provided at the first end of the slider locking device locking device oblique surface to decompose the force applied by the locking slider to the slider locking device into two components of force.

3. The lock device according to claim 2 , wherein:
the locking slider having an outward extension portion configured on the side surface which faces the slider locking device, the locking slider oblique surface is formed on the outward extension portion.

4. The lock device according to claim 2 , wherein:
the locking slider having an inwardly recessed cavity configured on the side surface which faces the slider locking device, and the locking slider oblique surface is formed on an internal surface of the cavity.

5. The lock device according to claim 4 , wherein:
the locking slider is a pawl, and a notch is provided on the slider locking device to receive the pawl.

6. The lock device according to claim 1 , wherein:
when the lock device is locked, the slider locking device is at a slider locking device locked position and locked, the locking slider is at the locking slider locked position, the lock hook is at the lock hook locked position, the slider locking device first end abuts against the locking slider to prevent the locking slider from moving away from the locking slider locked position, the locking slider first end abuts against the lock hook radial surface to prevent the lock hook from rotating away from the lock hook locked position;
when the lock device is opened, the slider locking device is not locked, the locking slider slides away from the locking slider locked position as the lock hook rotates away from the lock hook locked position, a force applied by the locking slider to the slider locking device first end enables the slider locking device to slide away from the slider locking device locked position.

7. The lock device according to claim 1 , wherein:
the second direction is perpendicular to the lock hook pivoting plane.

8. The lock device according to claim 1 , wherein the device further comprises:
a first elastic member mounted on the lock hook, the first elastic member generates a force for driving or blocking the pivoting of the lock hook.

9. The lock device according to claim 8 , wherein:
the first elastic member is a torsion spring.

10. The lock device according to claim 1 , wherein the device further comprises:
an elastic member for driving and blocking the reciprocatingly sliding of the locking slider in the first direction.

11. The lock device according to claim 10 , wherein:
the elastic member is a spring which abuts against the locking slider with one end and extends in the first direction.

12. The lock device according to claim 1 , wherein the housing further comprises:
an elastic member for driving and blocking the reciprocatingly sliding of the slider locking device in the second direction.

13. The lock device according to claim 12 , wherein:
the third elastic member is a spring which abuts against the slider locking device with one end and extends in the second direction.

14. The lock device according to claim 1 , wherein the lock device further comprises:
a locking member which locks the slider locking device at the slider locking device locked position when the lock device is locked.

15. The lock device according to claim 1 , wherein:
the locking slider, when viewed in the direction of the pivoting axis, has a first surface that extends in the first direction and a second surface that extends at an angle away from the first surface at a reflex angle from the first surface.

16. The lock device according to claim 1 , wherein:
the locking slider, when viewed in the direction of the pivoting axis, has a first surface that extends in a direction and a second surface that extends at an angle away from the first surface at a reflex angle from the first surface.

17. The lock device according to claim 1 , wherein:
the housing includes an opening into and out of which a door hook is respectively insert into and retract from the housing, and
the first direction is normal to a direction of travel of the door hook when the door hook is inserted into and retracted from the housing.

18. The lock device according to claim 1 , wherein:
the housing includes an opening into and out of which a door hook is respectively insert into and retract from the housing, and
the first direction is normal to a longitudinal axis of the opening.

19. The lock device according to claim 1 , wherein:
structure of the locking slider is always below a plane that is both parallel to the pivoting axis and parallel to the first direction, wherein the plane is between the pivoting axis and the locking slider.

20. An apparatus, comprising a chamber, a door for enclosing the chamber and a door lock for locking the door, wherein:
the door lock is the lock device according to claim 1 .

21. A lock device, comprising a housing including:
a lock hook mounted in the housing, the lock hook pivotally moves to and away from a lock hook locked position;
a locking slider for locking the lock hook, the locking slider having a locking slider first end which abuts against a radial surface of the lock hook, the locking slider is reciprocatingly slideable in a first direction normal to a direction of the lock hook pivoting axis following pivoting of the lock hook to move to or away from a locking slider locked position;
a slider locking device for locking the locking slider, the slider locking device is reciprocating slideable in a second direction following the reciprocatingly sliding of the locking slider in the first direction, the second direction crosses a lock hook pivoting plane,
wherein the locking slide
