Detailed Description

The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents and other technical solutions without departing from the spirit and scope of the invention.

It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in a generic and descriptive sense only and not for purposes of limitation, as the terms are used in the description to indicate that the referenced device or element must have the specified orientation, be constructed and operated in the specified orientation, and not for the purposes of limitation.

With reference to fig. 1 to 7 of the specification, a fixing mechanism for a box hook according to a preferred embodiment of the present invention is disclosed. Comprises a box 10, a pushing unit 20 and a hook unit 30, wherein the box 10 comprises a static cavity 11 and a dynamic cavity 12, and the dynamic cavity 12 is rotatably connected with the static cavity 11. The hook unit 30 is connected to the push unit 20.

Specifically, the pushing unit 20 includes a connecting component 21 and a pushing block 22, wherein the connecting component 21 includes a force applying rod 211 and a force arm rod 212. The push block 22 is movably mounted in the movable cavity 12, and the force application rod 211 is movably mounted in the movable cavity 12. The force application rod 211 is perpendicular to the force arm rod 212. The utility model discloses in, application of force pole 211 is provided with two, two application of force pole 211 is installed fixedly arm of force pole 212, and two application of force pole 211 is in the center department symmetry setting of arm of force pole 212. The arrangement is that when the worker pushes the push block 22, the force application rod 211 can equally push the force arm rod 212, so that the two ends of the force arm rod 212 are uniformly stressed.

The push block 22 is fixedly mounted on an end of the force application rod 211 remote from the force arm rod 212. Therefore, when the worker pushes the push block 22, the push block 22 gives a pushing force to the force application rod 211, and the force application rod 211 can push the force arm rod 212 to move into the cavity of the static cavity 11.

The hook unit 30 includes at least a first hook 31, at least a second hook 32 and at least an elastic member 33, wherein the first hook 31 is fixedly installed at both ends of the arm lever 212, and when the arm lever 212 moves, the first hook 31 can move together with the arm lever 212. When the movable cavity 12 is buckled with the static cavity 11, the first hook 31 is buckled with the second hook 32.

The elastic members 33 are the same in number as the first hooks 31 and are connected to the first hooks 31. That is, when the worker pushes the push block 22, the first hooks 31 installed at both ends of the arm lever 212 press the elastic member 33 with the same pushing force, so that both the first hooks 31 can be separated from the second hooks 32 at the same time.

More specifically, the first hook 31 includes a first fixing portion 311 and a first engaging portion 312. The first fixing portion 311 is formed with a mounting hole, wherein the diameter of the mounting hole is the same as the diameter of the arm lever 212. At the matching position of the arm-of-force lever 212 and the mounting hole, a plurality of anti-slip teeth 2121 are formed on the circumferential surface of the arm-of-force lever 212. That is, when the mounting hole is engaged with the arm lever 212, the anti-slip tooth 2121 can increase the friction force between the mounting hole and the arm lever 212, so that the first hook 31 is more stably mounted on the arm lever 212, and the first hook 31 is prevented from rotating on the arm lever 212, so that the first hook 31 and the second hook 32 are not locked together. The first engaging portion 312 is fixedly connected to the first fixing portion 311.

In addition, the second hook 32 includes a second fixing portion 321 and a second fastening portion 322, wherein the second fixing portion 321 is fixedly installed in the stationary cavity 11, and the second fastening portion 322 and the second fixing portion 321 are integrally formed.

The clamping positions of the first clamping portion 312 and the second clamping portion 322 form a clamping surface, wherein the clamping surface is a plane. When the clamping surfaces of the first clamping portion 312 and the second clamping portion 322 are in contact, the directions of the first clamping portion 312 and the second clamping portion 322 are opposite, so that the first clamping portion 312 is abutted to the second fixing portion 321, and the second clamping portion 322 is abutted to the first fixing portion 311. So as to achieve the maximum clamping surface area, and the first clamping hook 31 and the second clamping hook 32 are more stably matched.

Further, a fixing frame 40 is mounted on the movable chamber 12, wherein the fixing frame 40 is fixedly mounted on the movable chamber 12. At least one connecting block is arranged between the fixed frame 40 and the arm-of-force lever 212. The connecting block is sleeved on the arm lever 212, wherein the arm lever 212 can rotate in the connecting block, and the connecting block is fixedly installed on the fixing frame 40. The fixed frame 40 can make the arm-force rod 212 move together with the movable cavity 12.

The elastic element 33 is installed between the first fixing portion 311 of the first hook 31 and the fixing frame 40. One end of the elastic element 33 abuts against the first fixing portion 311, and the other end of the elastic element 33 abuts against the fixing frame 40. In the present invention, the elastic member 33 is always in an extended state, so the elastic member 33 provides a pushing force to the first hook 31, so that the first hook 31 is always close to the second hook 32. The elastic parts 33 are arranged at two ends of the arm-of-force lever 212, and when a worker applies force, the elastic parts 33 are stressed uniformly.

That is, when a worker needs to open the movable cavity 12 on the static cavity 11, the worker pushes the push block 22, so that the push block 22 moves to one end close to the static cavity 11; so that the push block 22 pushes the arm-of-force lever 212 to approach the static cavity 11; finally, when the arm lever 212 moves, the elastic element 33 is pressed, so as to separate the first hook 31 and the second hook 32, and separate the movable cavity 12 and the static cavity 11.

It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are given by way of example only and are not limiting of the invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
