The first mounting component is provided with a plug-in part for connecting to the vehicle frame. The plug-in part is provided with a plug-in hole. A plug-in groove is provided on one side of the plug-in part, and the plug-in groove communicates with the plug-in hole.

[0006] A snap-fit ​​connector is inserted into a connector slot. One end of the snap-fit ​​connector extends to the outside of the connector slot. The snap-fit ​​connector is provided with a snap-fit ​​hole. The snap-fit ​​connector can move within the connector slot so that the snap-fit ​​hole and the connector hole can partially or completely overlap.

[0007] According to an embodiment of this utility model, a wheel mounting bracket has at least the following advantages: When the connecting rod of the vehicle frame is installed with the bracket of this application, the user only needs to push the snap-fit ​​component so that the snap-fit ​​hole on the snap-fit ​​component can completely overlap with the insertion hole. At this time, the user only needs to insert the connecting rod of the vehicle frame into the snap-fit ​​hole and the insertion hole. Then, the snap-fit ​​component resets, and the snap-fit ​​component clamps and fixes the connecting rod of the vehicle frame onto the insertion part. Similarly, when the user needs to disassemble the connecting rod of the vehicle frame from the bracket of this application, he only needs to push the snap-fit ​​component so that the snap-fit ​​hole and the insertion hole can completely overlap again. At this time, the snap-fit ​​component is released from the connecting rod of the vehicle frame, and the user can pull out the connecting rod of the vehicle frame to complete the disassembly. The structure is simple and practical, and the disassembly and assembly are convenient.

[0008] According to an embodiment of the present utility model, a wheel mounting bracket has a plug groove including a circular groove and strip grooves disposed on both sides of the circular groove.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Reference Figures 1 to 4 This utility model provides a wheel mounting bracket, including a frame body, comprising a first mounting member 110 and a second mounting member fixedly connected in sequence. The first mounting member is provided with a plug-in portion 111 for connecting to a vehicle frame. The plug-in portion 111 is provided with a plug-in hole 1111, and a plug-in groove 120 is provided on one side of the plug-in portion 111, communicating with the plug-in hole 1111. A snap-fit ​​member 200 is inserted and connected to the plug-in groove, one end of the snap-fit ​​member 200 extending to the outside of the plug-in groove 120, and the snap-fit ​​member 200 is provided with a snap-fit ​​hole 210. The snap-fit ​​member 200 can move within the plug-in groove so that the snap-fit ​​hole 210 and the plug-in hole 1111 can partially or completely overlap. In addition, this application also provides a handcart (not shown) using the above-mentioned wheel mounting bracket.

[0032] When the connecting rod of the frame is installed with the bracket of this application, the user only needs to push the snap-fit ​​part 200 so that the snap-fit ​​hole 210 on the snap-fit ​​part 200 can completely overlap with the insertion hole 1111. At this time, the user only needs to insert the connecting rod of the frame into the snap-fit ​​hole 210 and the insertion hole 1111. Then the snap-fit ​​part 200 resets, and the snap-fit ​​part 200 clamps and fixes the connecting rod of the frame onto the insertion part 111. Similarly, when the user needs to disassemble the connecting rod of the frame from the bracket of this application, he only needs to push the snap-fit ​​part 200 so that the snap-fit ​​hole 210 and the insertion hole 1111 completely overlap again. At this time, the snap-fit ​​part 200 is released from the connecting rod of the frame, and the user can pull out the connecting rod of the frame to complete the disassembly. The structure is simple and practical, and the disassembly and assembly are convenient.

[0033] According to some embodiments of this application, the insertion slot 120 includes a circular slot 121 and strip slots 122 disposed on both sides of the circular slot 121. The circular slot 121 and the strip slots 122 are connected. The middle part of the snap-fit ​​member 200 is located in the circular slot 121, and the two ends of the snap-fit ​​member 200 are respectively located in the two strip slots 122. The mating structure of the insertion slot 120 and the snap-fit ​​member 200 is specifically defined. This structure helps the snap-fit ​​member 200 to move stably in the insertion slot 120 and ensures the reliability of the snap-fit ​​function.

[0034] Furthermore, the snap-fit ​​component 200 is provided with a disassembly hole 220, which is located in the middle of the snap-fit ​​component 200. The user can use an auxiliary tool to insert the tool from the circular groove 121 into the insertion groove 120 and hook it into the disassembly hole 220, thereby pulling the snap-fit ​​component 200. The user can operate the snap-fit ​​component 200 through the disassembly hole 220 when disassembly is required, facilitating the separation of the wheel mounting bracket from the frame and improving the maintainability of the bracket.

[0035] According to some embodiments of this application, a return spring is disposed within the insertion slot, with one end of the return spring abutting against the inner wall of the insertion slot and the other end abutting against the end of the snap-fit ​​member 200. By adding a return spring, the snap-fit ​​member 200 can automatically reset after movement, ensuring the stability and convenience of the snap-fit ​​function, eliminating the need for manual reset of the snap-fit ​​member 200, and improving the efficiency of installation and disassembly. Furthermore, a positioning block 230 is provided at the end of the snap-fit ​​member 200, and the positioning block 230 is inserted into the return spring. The positioning block 230 can better fix the return spring, ensuring the stability of the return spring's position during operation, avoiding the impact of the return spring's displacement on the normal reset of the snap-fit ​​member 200, and further improving the reliability of the entire snap-fit ​​structure.

[0036] According to some embodiments of this application, the insertion part 111 is further provided with a positioning cavity 130, which surrounds the insertion hole 1111 and is used for positioning and installing the frame and wheel mounting bracket. The addition of the positioning cavity 130 structure allows for more precise positioning of the frame and wheel mounting bracket during connection, ensuring accurate installation and preventing deviations in installation position from affecting the normal operation of the wheel and the stability of the bracket.

[0037] Furthermore, the positioning cavity 130 is provided with reinforcing ribs 140, and multiple reinforcing ribs 140 are arranged at intervals around the axis of the insertion hole 1111. The reinforcing ribs 140 can improve the strength and stability of the positioning cavity 130, making the positioning cavity 130 less prone to deformation when subjected to the pressure and impact force during frame installation, thereby ensuring the accuracy and reliability of positioning installation and extending the service life of the bracket.

[0038] According to some embodiments of this application, the second mounting component includes two opposing mounting plates 150, each mounting plate 150 having mounting holes 151 for wheel mounting. The two opposing mounting plates 150 and mounting holes 151 provide a stable mounting position for the wheel, ensuring a reliable connection between the wheel and the bracket, and enabling the wheel to operate normally.

[0039] According to some embodiments of this application, the first mounting component 110 and the second mounting component are injection molded as an integrated structure, which can reduce the number of parts of the bracket, reduce production costs, improve the overall strength and stability of the bracket, reduce the risk of failure caused by loosening of parts connection, and ensure the long-term reliable use of the bracket.
