Abstract

A locking apparatus is provided that relates to a fastener and is used to solve a problem that time and labor are consumed and installation efficiency is low in a locking process of an existing locking apparatus. The locking apparatus is configured to lock a first module and a second module, and includes a locking body that is installed on the first module and a locking piece that is installed on the second module. The locking body includes a housing and a rotating block disposed inside the housing, where the rotating block is connected to a handle that drives the rotating block to rotate out of or into the housing, and the locking piece has a notch that accommodates the rotating block. The present invention is used to implement locking between modules.

First claim

What is claimed is:

1. A locking apparatus configured to lock a first component part and a second component part, the locking apparatus comprising:
a locking body that is installed on the first component part; and
a locking piece that is installed on the second component part,
wherein the locking body comprises a housing and a rotating block disposed inside the housing,
wherein the rotating block comprises a ratchet structure,
wherein the rotating block is connected to a handle that drives the rotating block to rotate out of or into the housing,
wherein the locking piece comprises:
a body defining a notch;
a pawl; and
an unlocking button disposed on the pawl,

wherein the pawl protrudes out from the body defining the notch when the unlocking button is actuated,
wherein the unlocking button is configured to be manually pressed to separate an inverted tooth of the pawl from the ratchet structure,
wherein the notch is configured to receive the rotating block, and
wherein the pawl is configured to move and engage the ratchet structure to secure the rotating block within the locking piece.

2. The locking apparatus according to claim 1 , wherein a rotating shaft is further disposed in the locking body, wherein the rotating block is fixedly connected to one end of the rotating shaft, and wherein the handle is connected to the other end of the rotating shaft.

3. The locking apparatus according to claim 2 , wherein the handle is fixedly connected to the rotating shaft.

4. The locking apparatus according to claim 2 , wherein the handle is connected to the rotating shaft by using a spline.

5. The locking apparatus according to claim 4 , further comprising a fastening block installed on the first component part, wherein a pin hole is disposed on the fastening block, and a wherein pin body that cooperates with the pin hole is disposed on the handle.

6. The locking apparatus according to claim 5 , wherein a control button is farther disposed on the handle, and wherein the control button is connected to the pin body.

7. The locking apparatus according to claim 2 , wherein the locking piece further comprises a hinging shaft, and wherein the pawl is hingedly connected via the hinging shaft to the body defining the notch.

8. The locking apparatus according to claim 7 , wherein the pawl and the unlocking button form an L shape, and wherein the hinging shaft is located proximate to the unlocking button at an intersection of the pawl and the unlocking button.

9. The locking apparatus according to claim 2 , wherein the rotating block has a first surface and a second surface along an axial direction of the rotating shaft, wherein the second surface is farther away from the handle than the first surface, wherein the first surface is an inclined plane, and wherein the notch has a sidewall that leans against the inclined plane.

10. The locking apparatus according to claim 2 , wherein a distance between a free end of the handle and the rotating shaft is greater than a distance between an outer edge of the rotating block and the rotating shaft.

11. The locking apparatus according to claim 1 , wherein the pawl comprises a plurality of inverted teeth configured to receive and secure the ratchet structure of the rotating block.

12. The locking apparatus according to claim 11 , wherein the unlocking button is located on a side of the pawl that deviates from the plurality of inverted teeth.

13. The locking apparatus according to claim 1 , comprising four locking apparatuses that are symmetrically installed in positions close to four corners of the first component part and the second component part.

14. The locking apparatus according to claim 1 , wherein the housing is an open-ended cavity disposed on a sidewall of the first component part.

15. An apparatus, comprising:
a handle;
a locking body comprising a housing and a rotating block, wherein the rotating block is connected to the handle, wherein the handle drives the rotating block to rotate out of or into the housing, and wherein the rotating block comprises a ratchet structure; and
a locking piece comprising a body defining a notch, a pawl hinged to the body, and an unlocking button on the pawl, wherein the pawl is configured to move and engage the ratchet structure to secure the rotating block, wherein the pawl protrudes out from the body defining the notch when the unlocking button is actuated, and wherein the unlocking button is configured to be manually pressed to separate an inverted tooth of the pawl from the ratchet structure.

16. The apparatus according to claim 15 , wherein a rotating shaft is further disposed in the locking body, wherein the rotating block is fixedly connected to one end of the rotating shaft, and wherein the handle is connected to the other end of the rotating shaft.

17. The apparatus according to claim 15 , wherein the handle is fixedly connected to the rotating shaft.

18. An apparatus, comprising:
a rotating block comprising a ratchet structure;
a handle connected to the rotating block via a rotating shaft; and
a locking piece comprising a body, a pawl, and an unlocking button on the pawl, wherein the pawl is hinged to the body, wherein the pawl is configured to move and engage the ratchet structure to secure the rotating block, wherein the pawl protrudes out from the body when the unlocking button is actuated, and wherein the unlocking button is configured to be manually pressed to separate an inverted tooth of the pawl from the ratchet structure.

19. The apparatus according to claim 18 , wherein the rotating block is fixedly connected to one end of the rotating shaft, and wherein the handle is connected to the other end of the rotating shaft.

20. The apparatus according to claim 18 , wherein the pawl and the unlocking button form an L shape, wherein the locking piece further comprises a hinging shaft that hingedly connects the pawl to the body, and wherein the hinging shaft is located proximate to the unlocking button at an intersection of the pawl and the unlocking button.
