[0023] The following is in conjunction with the appendix Figure 1 To be continued Figure 8 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0024] Please see Figures 1-8 This utility model provides a self-locking buckle with square holes for server racks. The buckle includes a first limiting plate 1, with a buckle 11 coaxially arranged on one side of the first limiting plate 1. A pair of first sliding grooves 12 are symmetrically arranged on both sides of the bottom end of the inner wall of the buckle 11, the length of the first sliding grooves 12 being less than the internal length of the buckle 11. A slider 3 is arranged between the first sliding grooves 12, with rotating plates 31 hinged to the outer sides of both ends of the slider 3. A self-locking plate 32 is hinged to the outer side of the other end of the rotating plate 31, and the other end of the self-locking plate 32 is hinged to the inner wall of the buckle 11 at one end of the first limiting plate 1. The first limiting plate 1... The size is larger than that of the buckle 11. The first limiting plate 1 limits one end of the buckle 11, so that the first limiting plate 1 and the buckle 11 are located on both sides of the mounting hole. The hinge of the rotating plate 31 and the self-locking plate 32 is above the first slide groove 12. The slider 3 slides between the first slide groove 12, which drives the rotating plate 31 and the self-locking plate 32 on the slider 3 to rotate. When the slider 3 moves to the bottom of the buckle 11, the rotating plate 31 and the self-locking plate 32 are retracted into the buckle 11. When the slider 3 moves to the other end of the first slide groove 12, the rotating plate 31 and the self-locking plate 32 rotate and extend out of both sides of the buckle 11.

[0025] Please see Figures 1-8 The inner side of the first slide groove 12 is arc-shaped, and the side of the slider 3 is in contact with the inner side of the first slide groove 12; through the contact between the first slide groove 12 and the slider 3, the slider 3 slides tightly against the inner wall of the first slide groove 12.

[0026] Please see Figures 1-8 A second slide groove 14 is provided between the first slide groove 12 and the first limiting plate 1. A second limiting plate 21 is provided inside the second slide groove 14. The inner side of the second slide groove 14 is arc-shaped, and the side of the second limiting plate 21 is in contact with the side of the second slide groove 14. By the contact between the second slide groove 14 and the second limiting plate 21, the second limiting plate 21 slides tightly between the second slide groove 14. The two ends of the second limiting plate 21 extend beyond the two ends of the first slide groove 12, thereby limiting the slider 3 so that the slider 3 only slides between the first slide groove 12.

[0027] Please see Figures 1-8An unlocking lever 2 is provided at the center of one side of the second limiting plate 21, and a through hole 13 is provided at the center of the first limiting plate 1. The unlocking lever 2 passes through the through hole 13, and the size of the unlocking lever 2 is the same as the size of the through hole 13. By pushing the unlocking lever 2, the second limiting plate 21 moves inside the buckle 11.

[0028] Please see Figures 1-8 A push rod 22 is provided on the other side of the second limiting plate 21. The push rod 22 is coaxially arranged with the unlocking button 2. A fixing hole 34 is provided at the center of one side of the slider 3. The other end of the push rod 22 is located in the fixing hole 34. The size of the fixing hole 34 is the same as the size of the push rod 22. The second limiting plate 21 is moved by the unlocking button 2, which drives the push rod 22 to move. The push rod 22 pushes the slider 3 to move between the first slide groove 12. One end of the push rod 22 is fixed by the fixing hole 34, so that the push rod 22 and the slider 3 move synchronously.

[0029] Please see Figures 1-8 A reset spring 4 is provided between the other side of the slider 3 and the bottom inner side of the buckle 11. A second mounting groove 33 is provided at the center of the side of the slider 3, and a first mounting groove 15 is provided at the center of the bottom inner side of the first limiting plate 1. The two ends of the reset spring 4 are respectively installed between the second mounting groove 33 and the first mounting groove 15. The reset spring 4 is fixed by the second mounting groove 33 and the first mounting groove 15. When the unlocking button 2 pushes the slider 3 to move towards the bottom end of the buckle 11, it compresses the reset spring 4. After the unlocking button 2 no longer applies pressure, the reset spring 4 drives the slider 3 to reset.

[0030] During use, when installing the buckle 11, first press the unlocking lever 2. The unlocking lever 2 pushes the second limiting plate 21 to move backward. At the same time, the second limiting plate 21 pushes the push rod 22 to move the slider 3 backward. When the slider 3 moves, it drives the rotating plate 31 and the self-locking plate 32 to rotate to a horizontal state. Then, insert the buckle 11 into the fixing hole, release the unlocking lever 2, and the slider 3 will be pushed forward by the spring. The slider 3 drives the rotating plate 31 and the self-locking plate 32 to achieve the self-locking effect. When removing the buckle 11, first press the unlocking lever 2 to push the slider 3 to move backward, driving the rotating plate 31 and the self-locking plate 32 to rotate to a horizontal state. Then, pull the buckle 11 out of the fixing hole.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
