[0041] Reference Figure 1 In one embodiment of the present application, a rack 100 is provided. Specifically, the rack 100 includes a frame body 10 and a clamping assembly 20. The frame body 10 includes two first frame parts 11 arranged at intervals. Each first frame part 11 is provided with a clamping assembly 20. For example, the first frame part 11 can be a plate. Figure 2The clamping assembly 20 includes a hinge member 21 and a first reset member 22. The hinge member 21 includes a fixed page 211, a movable page 212 and a rotating shaft 213 passing through the fixed page 211 and the movable page 212. The fixed page 211 is connected to a first frame portion 11. Exemplarily, a connecting nail can be passed through the fixed page 211 and the first frame portion 11 to achieve the connection between the two. The movable page 212 is arranged on one side of the fixed page 211 relative to the other first frame portion 11. The movable page 212 is arranged relative to the adjacent first frame portion 11 to limit the clamped part (not shown in the figure). Exemplarily, the clamped part may include a circuit board. The first restoring member 22 includes a force arm 221, a spring coil 222 and a force arm 221 connected in sequence, that is, the first restoring member 22 is a torsion spring structure, one force arm 221 abuts against the surface of the movable page 212 relative to the fixed page 211, and the other force arm 221 abuts against the surface of the fixed page 211 relative to the movable page 212, and the rotating shaft 213 also passes through the spring coil 222.

[0042] During specific use, the movable page 212 is bent away from the adjacent first frame part 11 to form a clamping gap. At this time, the angle between the two force arms 221 becomes smaller. After the clamped part is placed in the clamping gap, the bending force is cancelled, and the angle gradually becomes larger to allow the first reset part 22 to restore its deformation. At this time, the force arm 221 abutting against the movable page 212 prompts the movable page 212 to abut against the clamped part, thereby completing the clamping operation of the clamped part.

[0043] In the present application, since the clamping assembly 20 includes a hinge part 21 and a first reset part 22 of a torsion spring structure, and a force arm 221 of the first reset part 22 abuts against the surface of the movable leaf 212 of the hinge part 21, the movable leaf 212 can be opened and closed relative to the first frame part 11, and the force arm 221 can provide a clamping force during the opening and closing process. Therefore, the bracket 100 can be adaptively opened to a predetermined angle according to the size of the clamped part to perform a clamping operation, thereby facilitating improving the clamping adaptability of the bracket 100. Therefore, the bracket 100 can reduce the user's fixture cost.

[0044] In some embodiments, reference Figure 2In the same clamping assembly 20, the number of hinges 21 and first reset members 22 is at least two and they are arranged one by one. In this embodiment, each clamping assembly 20 includes two hinges 21 and two first reset members 22. At least two hinges 21 are arranged at intervals and are arranged on the same side of the frame 10, so that two adjacent movable pages 212 are arranged opposite to each other, and two adjacent fixed pages 211 are arranged opposite to each other. The clamping assembly 20 also includes a connecting member 23, which is fixed to one end of each movable page 212 of the same clamping assembly 20 relative to the adjacent first frame part 11, so that the connecting member 23 is located between the movable page 212 and the adjacent first frame part 11. Exemplarily, the connecting member 23 can be a cylinder to help avoid clamping damage caused by the connecting member 23. The connecting member 23 helps to increase the clamping width of the clamping assembly 20, thereby helping to improve the clamping stability of the hanger 100.

[0045] In some embodiments, reference Figures 2 to 4The first frame portion 11 is provided with a mounting hole 111, and the mounting hole 111 has two openings 1111 arranged at intervals. The opening 1111 is located between two adjacent hinge members 21 and is arranged on a side of the connecting member 23 relative to the fixed leaf 211. One opening 1111 is arranged relative to one hinge member 21, that is, one opening 1111 is arranged between another opening 1111 and one hinge member 21. The clamping assembly 20 further includes a rotating arm 24, a mounting seat 25, a snap member 26 and a second reset member 27. The rotating arm 24 is arranged between the adjacent hinge members 21 and the opening 1111, and the rotating arm 24 is connected to the connecting member 23. Exemplarily, one end of the rotating arm 24 relative to the other first frame portion 11 can be connected to the connecting member 23 by a connecting nail. The mounting seat 25 is arranged on the side of the first frame part 11 away from the hinge part 21 to cover the mounting hole 111. For example, the mounting seat 25 can be detachably connected to the first frame part 11. For example, a connecting nail can be passed through the mounting seat 25 and the first frame part 11 to achieve a detachable connection between the two. The buckle 26 is arranged in the mounting hole 111. The buckle 26 includes a limit arm 261 and an operating arm 262 connected to each other. The limit arm 261 passes through the opening 1111 adjacent to the rotating arm 24. The limit arm 261 is used to abut against the surface of the rotating arm 24 away from the first frame part 11, and the operating arm 262 passes through the other opening 1111. The second reset member 27 is also disposed in the mounting hole 111. The second reset member 27 is connected between the mounting seat 25 and the operating arm 262. For example, the mounting seat 25 may be recessed relative to the surface of the first frame portion 11 to form a first mounting groove 251, and the bottom wall of the first mounting groove 251 may be recessed to form a second mounting groove 252. One end of the second reset member 27 may be fixed in the second mounting groove 252. For example, the limiting arm 262 may be recessed relative to the surface of the mounting seat 25 to form a third mounting groove 2621, and the other end of the second reset member 27 may be fixed in the third mounting groove 2621. The operating arm 262 cooperates with the second reset member 27 to drive the limiting arm 261 to separate from the rotating arm 24. Specifically, when the operating arm 262 is bent in a direction away from the limiting arm 261 by an external force, the second reset member 27 may be bent and deformed, so that the limiting arm 261 is separated from the rotating arm 24. For example, the second reset member 27 may be a coil spring.

[0046] In specific use, the external force causes the movable page 212 to rotate in the direction away from the first frame part 11, so that the angle between the fixed page 211 and the movable page 212 becomes smaller, and the end of the rotating arm 24 away from the connecting member 23 moves toward the first frame part 11. At this time, the limit arm 261 can be used to abut against the rotating arm 24, so as to prevent the movable page 212 from moving toward the first frame part 11 again when the external force disappears. Therefore, the structural setting of the clamping assembly 20 is conducive to avoiding repeated bending of the movable page 212, thereby improving the user's operating efficiency.

[0047] In some embodiments, reference Figure 2 and Figure 4 The limiting arm 261 includes a connecting portion 2611 and a boss 2612. The connecting portion 2611 is connected to the operating arm 262 and passes through the opening 1111. The boss 2612 is used to abut against the surface of the rotating arm 24 away from the first frame portion 11. The boss 2612 is provided on a side of the first frame portion 11 close to the opening 1111. The boss 2612 is provided on the connecting portion 2611 relative to the rotating arm 24. The structure of the limiting arm 261 is conducive to improving the limiting stability.

[0048] In another embodiment, the limiting arm 261 may be an arc-shaped structure that is bent away from the rotating arm 24 .

[0049] In some embodiments, reference Figure 2 The rotating arm 24 includes a first arm portion 241 and a second arm portion 242 which are arranged at an angle and connected to each other. The first arm portion 241 is connected to the connecting member 23, and the limiting arm 261 is used to abut against the second arm portion 242. The opening of the angle can be arranged away from the first frame portion 11.

[0050] In some embodiments, reference Figure 1 The frame 10 further includes two second frame parts 12 arranged at intervals, each second frame part 12 is connected to two first frame parts 11, and illustratively, the first frame part 11 and the second frame part 12 can be arranged vertically. The clamping assembly 20 is arranged between the two second frame parts 12. The structure of the frame 10 facilitates the overall movement of the hanger 100.

[0051] In some embodiments, at least one first frame portion 11 is movable relative to another first frame portion 11 to adjust the distance between the two first frame portions 11. In this embodiment, the first frame portion 11 disposed at the bottom is movable.

[0052] In some embodiments, reference Figure 1 and Figure 3 , the second frame part 12 is provided with a strip through hole 121, the strip through hole 121 is oriented along the arrangement direction of the two first frame parts 11, and the second frame part 12 is arranged on the side of the first frame part 11 away from the clamping assembly 20, so that the first frame part 11 at least covers part of the strip through hole 121. The hanger 100 also includes a screw 30 and a nut 40, the threaded end of the screw 30 passes through the first frame part 11 and is arranged in the strip through hole 121, the nut 40 is arranged in the strip through hole 121 and abuts against the second frame part 12, and the nut 40 is screwed to the screw 30. In specific use, the nut 40 can be placed at different positions in the strip through hole 121, so that the distance between the two first frame parts 11 can be adjusted after the screw 30 passing through the first frame part 11 is connected with the nut 40. The strip through hole 121 cooperates with the screw 30 and the nut 40 to widen the adjustment range of the distance and also ensure the connection strength of the first frame part 11 and the second frame part 12.

[0053] In another embodiment, the strip-shaped through hole 121 can be replaced with a plurality of through holes arranged at intervals, and the plurality of through holes can be arranged along the arrangement direction of the two first frame parts 11 .

[0054] In some embodiments, reference Figure 1 and Figure 2 At least two clamping assemblies 20 are arranged on the same side of the first frame portion 11. In this embodiment, each first frame portion 11 is connected to four clamping assemblies 20. For example, two adjacent clamping assemblies 20 can be arranged at intervals, and the movable pages 212 of two adjacent clamping assemblies 20 are arranged opposite to each other, and the fixed pages 211 of two adjacent clamping assemblies 20 are arranged opposite to each other. Increasing the number of clamping assemblies 20 is conducive to improving the clamping stability of the rack 100.

[0055] In some embodiments, reference Figure 1 The rack 100 includes at least two rack bodies 10 arranged at intervals, and the second rack parts 12 of two adjacent rack bodies 10 are arranged opposite to each other. The rack 100 also includes a base 50, which is connected to one end of each second rack part 12 relative to the ground to integrate multiple rack bodies 10. For example, the base 50 and each second rack part 12 can be connected by connecting nails through them. The base 50 facilitates the simultaneous movement of multiple rack bodies 10.

[0056] In some embodiments, the strip-shaped through hole 121 may be provided at one end of the second frame portion 12 connected to the base 50 to reduce the adjustment height of the hanger 100 , thereby facilitating the convenience of adjusting the distance of the hanger 100 .

[0057] In some embodiments, the rack 100 further includes four wheel sets 60 arranged at intervals, and the four wheel sets 60 are evenly arranged at opposite ends of the base 50, that is, two wheel sets 60 are connected to one end of the base 50, and another two wheel sets 60 are connected to the other end of the base 50.
