Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] Refer to Figure 1-12, A locking structure for a communication chassis, comprising a spring button 1, a chassis cover plate 2, a tension spring 3, a locking hook 4, a hook cover plate 5, and a chassis cavity 6. The spring button 1 is provided with a circular button 11, a limiting boss 12, and a compression spring 13. The bottom surface of the chassis cover plate 2 is provided with a hook groove 21 and a spring groove 24, and the hook groove 21 and the spring groove 24 are connected. The locking hook 4 is placed on the hook groove 21. The hook groove 21 is provided with a square opening groove 22, and a push-pull button 42 is placed on the square opening groove 22. A circular through hole 23 is opened on the hook groove 21, and the spring button 1 is placed on the circular through hole 23. The tension spring 3 is placed in the spring groove 24. One side of the spring groove 24 is provided with a spring fixing stud 25 installed on the bottom surface of the chassis cover plate 2. One end of the tension spring 3 is fixed to the spring fixing stud 25 by a screw. Both the left and right ends of the locking hook 4 are provided with two locking tongues 41. Two locking slots 61 are opened on one inner wall of the chassis cavity 6, and the locking tongues 41 are adapted to the locking slots 61. A push-pull button 42 with a square shape is provided at the middle crossbeam position of the locking hook 4. A square structure protrudes from the middle of the crossbeam of the locking hook 4 and is provided with a fixing stud 43. One end of the tension spring 3 is fixed to the fixing stud 43 by a screw. A spring button limiting groove one 44 and a spring button limiting groove two 45 are opened at the middle crossbeam position of the locking hook 4, and the spring button limiting groove one 44 and the spring button limiting groove two 45 are connected. The hook cover plate 5 is provided with a spring button circular groove 51, a tension spring groove 52, and a number of threaded through holes 53. The compression spring 13 is placed in the spring button circular groove 51, and the tension spring 3 is placed in the tension spring groove 52.

[0029] In the present invention, a rotating round hole 27 is provided on one side of the chassis cover plate 2, and a rotating cylinder 62 is provided on one side of the chassis cavity 6. The rotating round hole 27 is adapted to the rotating cylinder 62.

[0030] In the present invention, a chassis cover plate skirt 28 is provided around the chassis cover plate 2. The chassis cavity 6 is a square unsealed box body, and a mating plane 63 is provided around the chassis cavity 6. The mating plane 63 is adapted to the chassis cover plate skirt 28.

[0031] In the present invention, the locking hook 4 is made of a metal material with relatively high yield strength and tensile strength, and is integrally U-shaped.

[0032] In the present invention, the width of the spring button limiting groove one 44 is slightly larger than the diameter of the circular button 11 and smaller than the diameter of the limiting boss 12; the diameter of the spring button limiting groove two 45 is slightly larger than the diameter of the limiting boss 12.

[0033] In the present invention, a number of threaded holes 26 are opened on the bottom surface of the chassis cover plate 2, and the hook cover plate 5 is fixed to the chassis cover plate 2 by screws and the threaded holes 26.

[0034] In the present invention, the hook cover plate 5 is fixed to the chassis cover plate 2 by screws and threaded through holes 53.

[0035] In the present invention, the locking hook 4 is enclosed on the chassis cover plate 2 by the hook cover plate 5 with screws.

[0036] In the present invention, the number of tension springs 3 can be increased or decreased according to the use environment to suit the specifications of the chassis; the stretching amount of the tension spring 3 can be appropriately lengthened, and the size of the hook groove 21 can be appropriately increased to enhance the resilience of the locking hook; the number of lock tongues 41 and locking slots 61 can be appropriately increased or decreased according to the size of the communication chassis to improve the reliability of the locking function.

[0037] The usage method of the present invention is as follows:

[0038] When the communication chassis is in the open / closed state, the locking hook 4 is at the left end of the hook groove 21. At this time, the tension spring 3 is in a slightly stretched state and has a certain resilience tension. Due to the limiting effect of the hook groove 21, the tension spring cannot continue to rebound. At this time, the limiting boss on the spring button 1 is in contact with the surface of the locking hook 4, and the circular button 11 is stuck in the first spring button limiting groove 44 of the locking hook 4. At this time, the compression spring 13 is in a compressed state and has a certain resilience. Since the button limiting boss 12 is in contact with the locking hook 4, the spring button 1 cannot move upward, and the compression spring 13 can only be in a compressed state; when the chassis cover plate 2 covers the chassis cavity 6, the lock tongue 41 enters the locking slot. At this time, the chassis is in the open / closed state and cannot be locked;

[0039] When an external force pushes the push-pull button 42 to move to the other side, the locking hook 4 is at the right end of the hook groove 21. At this time, the tension spring 3 is stretched greatly and is in a stretched state, having a very large resilience tension. Since the locking hook 4 moves to the right in the hook groove, the second spring button limiting groove 45 coincides with the circular through hole 23, and the limiting boss 12 on the spring button 1 is no longer in contact with the locking hook 4. The spring button 1 moves upward under the elastic force of the compression spring 13, and the spring button 1 enters the second spring button limiting groove 45, making the limiting boss 12 in contact with the chassis cover plate 2. At this time, the spring button 1 restricts the locking hook 4 from being pulled back to its original position by the tension spring 3, playing a limiting role. When the chassis cover plate 2 covers the chassis cavity 6, the lock tongue 41 enters the locking slot. At this time, the chassis is in the closed state, realizing the closing function;

[0040] After the chassis completes the closing function, the closing function needs to be released to open the chassis. Just press the spring button 1 with an external force. At this time, the compression spring 13 is compressed under force, and the spring button 1 moves downward. At this time, since the stretching spring 3 is stretched to a large extent, the stretching spring 3 has a large resilience. When the limit boss 12 on the spring button 1 moves downward to below the locking catch 4, the spring button 1 no longer has a limiting effect on the locking catch 4. The locking catch 4 receives the pulling force of the stretching spring 3, causing the locking catch 4 to move to the left side of the catch groove 21 and stop moving. When the external force disappears, the compression spring 13 resets, applying a certain elastic force to the spring button 1. The spring button 1 moves upward, and the limit boss 12 fits with the locking catch 4. At this time, the entire locking structure reaches a force balance and stops moving. At this time, the chassis locking function is released, and the chassis can be opened.

[0041] As described above, it is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
