[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 3 As shown, the present invention provides a quick-release buckle for fixing a plate structure 1 to a box body, wherein the plate structure 1 has a limiting hole. The quick-release buckle includes a buckle body 3 and a base 2. The base 2 is designed to be connected to the box body, and the buckle body 3 is rotatably connected to the base 2. The buckle body 3 is provided with a first tenon 31 and a slot 32. When the buckle body 3 rotates, it can move the first tenon 31 and the slot 32 closer to or away from the base 2, that is, the rotation of the buckle body 3 can move the first tenon 31 and the slot 32 closer to or away from the plate structure 1. The opening direction of the slot 32 is at an angle to the extension direction of the first tenon 31. The first tenon 31 includes a first deformable part 311 and a first latch 312. The first latch 312 is disposed on the first deformable part 311, and the first deformable part 311 can elastically deform so that the first latch 312 can pass through the limiting hole. The quick-release buckle has a release state and a limiting state. In the limiting state, the buckle body 3 rotates until the plate structure 1 is inserted into the slot 32, the wall of the slot 32 abuts against the side wall of the plate structure 1, the first deformable part 311 passes through the limiting hole, and the first latch 312 engages with the side of the plate structure 1 opposite to the buckle body 3. In the release state, the buckle body 3 rotates until the first latch 31 and the slot 32 disengage from the plate structure 1. With this design, limiting and releasing the plate structure 1 can be achieved simply by rotating the buckle body 3, without the need for bolts or rotating tools, making the operation simple and quick.

[0024] Understandably, since the opening direction of the slot 32 is at an angle to the extension direction of the first tenon 31, in the limited position, on the one hand, the first tenon 31 passes through the limiting hole and the first latch 312 engages with the side of the plate structure 1 away from the buckle body 3, so that the plate structure 1 can only rotate around the axial direction of the first tenon 31. The groove wall of the slot 32 abuts against the side wall of the plate structure 1, thereby restricting the rotation of the plate structure 1 around the axial direction of the first tenon 31, ultimately limiting the plate structure 1 to the buckle body 3. On the other hand, the first latch 312 can cooperate with the groove wall of the slot 32 near the base 2 to bear the weight of the plate structure 1, ensuring the load-bearing capacity of the quick-release buckle. When the first tenon 31 and the slot 32 disengage from the plate structure 1, the limiting relationship between the plate structure 1 and the buckle body 3 is released.

[0025] When using the quick-release buckle to limit the position of the plate structure 1, firstly, align the limiting hole of the plate structure 1 with the first tenon 31, and overlap the edge of the plate structure 1 with the edge of the opening of the slot 32. Then, rotate the buckle body 3 to move the first tenon 31 and the slot 32 closer to the plate structure 1. During this process, the first tenon 31 gradually inserts into the limiting hole, and at the same time, the plate structure 1 is deformed by the pressure of the side wall of the slot 32 until the plate structure 1 is inserted into the slot 32. When releasing the quick-release buckle from limiting the plate structure 1, press the plate structure 1 with external force to fix its position, and rotate the buckle body 3 in a direction away from the plate structure 1 to make the first tenon 31 and the slot 32 tend to disengage relative to the plate structure 1. During this process, the first tenon 31 gradually moves out of the limiting hole, and at the same time, the plate structure 1 is deformed by the pressure of the side wall of the slot 32 until the plate structure 1 moves out of the slot 32.

[0026] For example, the angle between the opening direction of the slot 32 and the extending direction of the first tenon 31 can be 90° or any other non-zero angle, as long as it satisfies the condition that "the first tenon 31 and the slot 32 cooperate to confine the board structure 1 within the buckle body 3". The board structure 1 can be a circuit board or other plate-like structure.

[0027] Optionally, the plate structure 1 is provided with multiple limiting holes, and multiple quick-release buckles can be provided, with each quick-release buckle corresponding to one of the limiting holes. Using multiple quick-release buckles to limit the plate structure 1 increases the stability of the limiting of the plate structure 1. Specifically, the plate structure 1 is provided with four limiting holes arranged in a rectangular array, allowing the quick-release buckles to limit the plate structure 1 from four directions.

[0028] Furthermore, the slot 32 is a U-shaped slot, and the first latch 31 is located on the slot wall of the U-shaped slot away from the base 2. In the limited position, the first latch 312 engages with the side of the plate structure 1 away from the buckle body 3, and the bottom wall of the U-shaped slot can abut against the side wall of the plate structure 1. With this configuration, the plate structure 1 is confined to the buckle body 3. On the one hand, "the first latch 31 is located on the slot wall of the U-shaped slot away from the base 2" makes the structure of the buckle body 3 more compact, facilitating the quick-release buckle to work in a confined space. On the other hand, "the slot 32 is a U-shaped slot" is not only suitable for plate structures 1 of different widths, but also extends through the buckle body 3 along the extension direction of the U-shaped slot, reducing the weight of the buckle body 3.

[0029] Optionally, the thickness of the slot 32 along the thickness direction of the plate structure 1 is greater than the thickness of the plate structure 1. Since the first latch 31 is provided with a first latch tongue 312, and the first latch tongue 312 can engage with the side of the plate structure 1 away from the buckle body 3, the movement of the plate structure 1 along its own thickness direction can be limited by the first latch 31. Therefore, while ensuring that the plate structure 1 can be limited to the buckle body 3, by setting that "the thickness of the slot 32 along the thickness direction of the plate structure 1 is greater than the thickness of the plate structure 1", the friction between the upper and lower surfaces of the plate structure 1 and the sidewall of the slot 32 can be reduced during the deformation and insertion of the plate structure 1 into the slot 32, thereby reducing the possibility of damage to the plate structure 1.

[0030] In other embodiments, the slot 32 can be configured as a rectangular slot, adapted to the surface shape of the plate structure 1. In the limited position, the plate structure 1 is clamped by the slot wall of the slot 32 so that the plate structure 1 can only move along the opening direction of the slot 32. At this time, the first tenon 31 can be configured as a column, and the columnar first tenon 31 inserted into the limiting hole can restrict the movement of the plate structure 1 along the opening direction of the slot 32, thereby limiting the plate structure 1 to the buckle body 3.

[0031] Furthermore, along the opening direction of the slot 32, the length of the slot wall of the slot 32 away from the base 2 is greater than the length of the slot wall of the slot 32 close to the base 2. Since the quick-release buckle needs to overlap the edge of the plate structure 1 with the edge of the slot 32 opening when limiting the plate structure 1, and utilizes the deformation of the plate structure 1 to insert the first latch 31 into the limiting hole, if the length of the slot wall of the slot 32 close to the base 2 is too long, it will cause excessive deformation of the plate structure 1 during insertion into the slot 32. On the one hand, this may cause significant friction between the upper and lower surfaces of the plate structure 1 and the sidewall of the slot 32 during movement, leading to damage to the plate structure 1; on the other hand, excessive deformation may cause permanent deformation or breakage of the plate structure 1. Therefore, setting the length of the slot wall of the slot 32 away from the base 2 to be greater than the length of the slot wall of the slot 32 close to the base 2 can avoid excessive deformation of the plate structure 1, thereby minimizing damage, permanent deformation, or breakage of the plate structure 1.

[0032] For example, a guide structure is formed at the edge of the groove wall near the base 2 of the slot 32. During the gradual insertion of the plate structure 1 into the slot 32, this guide structure remains in contact with and applies force to the plate structure 1. The guide structure not only reduces the pressure exerted by the slot 32 against the plate structure 1 at the edge of the groove wall near the base 2, thus reducing the possibility of frictional damage, but also reduces the degree of deformation of the plate structure 1, further reducing the possibility of permanent deformation or breakage. Optionally, the guide structure is a chamfered inclined plane or a protruding R-shaped arc surface.

[0033] Furthermore, multiple first latches 31 are provided, and the multiple first latches 31 are arranged in an array with intervals between them. When the first latch 31 is inserted into the limiting hole and moves in the limiting hole, the first latch 312 is pressed by the inner wall of the limiting hole, which forces the first deformable part 311 to deform and the multiple first deformable parts 311 to move closer to each other, so that the first latch 312 can enter the limiting hole and pass through the limiting hole as the first latch 31 moves, thereby enabling the first latch 312 to engage with the side of the plate structure 1 away from the buckle body 3.

[0034] Optionally, the cross-section of the limiting hole can be circular or polygonal. For example, when the cross-section of the limiting hole is circular, the plurality of first deformable portions 311 are arranged in a circular array; when the cross-section of the limiting hole is rectangular, the plurality of first deformable portions 311 are arranged in a rectangular array. This arrangement, on the one hand, allows the first latch 312 to fully contact the inner wall of the limiting hole, thereby forcing the first deformable portion 311 to deform; on the other hand, it increases the contact area between the first latch 312 and the side of the plate structure 1 opposite to the latch body 3, improving the stability of the latching action.

[0035] Furthermore, the first latch 31 also includes a first guide portion 313. The first guide portion 313 is connected to the end of the first latch 312 away from the latch body 3. Along the extending direction of the first latch 31, the thickness of the first guide portion 313 gradually decreases perpendicular to the extending direction of the first latch 31. When the first latch 31 is inserted into the limiting hole, the sidewall of the first guide portion 313 can provide guidance for the insertion of the first latch 312 into the limiting hole, reducing the difficulty of aligning the first latch 31 with the limiting hole and improving operational flexibility.

[0036] For example, the thickness of the end of the first guide portion 313 connected to the first latch 312 is equal to the thickness of the first latch 312. This arrangement allows for a smooth transition between the first guide portion 313 and the first latch 312, preventing jamming when the first latch 31 is inserted into the limiting hole and reducing the possibility of insertion failure.

[0037] Furthermore, the buckle body 3 includes a connecting part 33, a limiting part 34, and an operating part 35. The connecting part 33 is rotatably connected to the base 2. The limiting part 34 is provided with a first latch 31 and a latching groove 32. The connecting part 33 connects the limiting part 34 and the operating part 35. With this configuration, the user can move the operating part 35 to drive the limiting part 34 and its first latch 31 and latching groove 32 to rotate, improving operational flexibility.

[0038] For example, the end of the operating part 35 away from the connecting part 33 extends away from the first latch 31. This arrangement increases the distance between the rotation axes of the operating part 35 and the connecting part 33, thereby achieving a "lever" effect and reducing the difficulty of operation for the user. Specifically, taking the quick-release buckle in the limited position as an example, the end of the operating part 35 away from the connecting part 33 extends obliquely upward in the direction away from the limiting part 34. When the limited position is released, the user only needs to press the end of the operating part 35 away from the connecting part 33 to obtain the maximum torque, thereby driving the limiting part 34 and its first latch 31 and latch 32 to rotate and disengage from the plate structure 1.

[0039] Furthermore, a connecting groove is formed on the base 2. The connecting part 33 is accommodated in the connecting groove. Each of the two opposite walls of the connecting groove is provided with a first mounting hole, and the connecting part 33 is provided with a second mounting hole. The quick-release buckle also includes a pin 4. The pin 4 passes through both the first and second mounting holes. The pin 4 is interference-fitted with the first mounting hole and clearance-fitted with the second mounting hole. This design not only ensures the stability of the rotating shaft of the connecting part 33 (i.e., the pin 4) but also ensures the flexibility of the connecting part 33's rotation around the shaft.

[0040] For example, the distance between the two opposite walls of the connecting groove is equal to or slightly greater than the thickness of the connecting portion 33. This minimizes wobbling when the connecting portion 33 rotates around the axis, improving operational stability.

[0041] Furthermore, a second latch 21 is provided on the base 2. The second latch 21 is configured to latch the base 2 onto the housing. The second latch 21 facilitates the detachable connection between the base 2 and the housing, improves the flexibility of the quick-release buckle, and also facilitates the repair or replacement of damaged quick-release buckles.

[0042] For example, the second latch 21 includes a second deformed portion and a second latch tongue. The second latch tongue is disposed at the end of the second deformed portion away from the base 2, so that the overall cross-section of the second latch 21 is "L"-shaped. An "L"-shaped groove is provided at the corresponding position on the housing. After the second latch 21 is inserted into the groove, it can engage with the groove wall, thereby installing the base 2 onto the housing.

[0043] Optionally, the second latch 21 also includes a second guide portion. The second guide portion is connected to the end of the second latch tongue away from the base 2. This reduces the difficulty of aligning the second latch 21 with the recess in the housing and improves operational flexibility.

[0044] In some embodiments, multiple second latches 21 are provided. Multiple second latches 21 are located on the side of the base 2 opposite to the latch body 3. The multiple second latches 21 are spaced apart from each other. This arrangement, using multiple spaced second latches 21 to install the base 2 onto the housing, improves connection stability. On the one hand, it minimizes the risk of the quick-release latches detaching due to the reaction force generated when limiting the plate structure 1; on the other hand, it minimizes the risk of the quick-release latches detaching during long-term use, preventing the plate structure 1 from failing to limit or shifting.

[0045] The present invention also provides a server, including a chassis (not shown in the figure), a plate structure 1, and a quick-release buckle as described in the present invention, the quick-release buckle being connected to the chassis and capable of confining the plate structure 1 within the chassis.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
