Description

Technical Field

[0001] The utility model relates to the technical field of wheel hubs, in particular to a wheel hub with a positioning and adjusting function. Background Art

[0002] A wheel hub is a component made of metal or alloy installed on a vehicle's tire. Its main function is to provide support and transmit driving force for the vehicle by contacting the ground. A wheel hub is usually composed of spokes and spoke covers between the spokes, and some modern wheels are one-piece structures. In addition to basic functions, wheels can also serve as aesthetic decoration. The design of modern car wheels is very diverse, with a variety of styles, shapes and materials to choose from. Some high-end models can also choose specially customized luxury wheels to increase the luxury and uniqueness of the vehicle.

[0003] After the existing wheel hub is installed on the vehicle's drive shaft, its bolts or nuts are located in the installation holes. When the vehicle is driving on a road with many stones, the stones are easily splashed into the installation holes, and foreign objects are inevitably introduced into the installation holes, which makes it impossible for the removal tool to clamp the nuts for removal when replacing or repairing the tire.

[0007] A threaded rod, the threaded rod passes through the fixed plate and is threadedly connected, the threaded rod passes through and is threadedly connected with a sealing block, the support rod limits the sealing block, so that when the threaded rod rotates, the sealing block does not rotate with it, but gradually pushes the support rod to insert into the fixed plate, and the sealing block gradually inserts into the groove for sealing, and at the same time the telescopic spring is compressed, and a groove is opened on the surface of the positioning plate;

[0008] A fitting groove is provided on the surface of the fixed plate, a sliding groove is provided on the inner side of the fitting groove, a push rod is slidably connected to the inner side of the sliding groove, a sealing plate is fixedly connected to the right side of the push rod, and the push rod will be gradually pushed when the elastic sheet is flattened. When the fitting plate, the elastic sheet and the fitting groove are fully fitted, the elastic sheet will push the push rod to the maximum distance, thereby causing the push rod to push the sealing plate to block the round hole.

[0009] Preferably, a positioning rod is fixedly connected to the inner side of the slide groove, and the positioning rod passes through the push rod and is slidably connected.

[0010] Preferably, a return spring is fixedly connected to the left side of the push rod, and one end of the return spring away from the push rod is fixedly connected to the inner side of the slide groove.

[0011] Preferably, an elastic sheet is fixedly connected to the top surface of the push rod, and an engaging plate is hingedly connected to one end of the elastic sheet away from the push rod. When the sealing block is gradually inserted into the groove, the sealing block will first resist the engaging plate, and gradually push the engaging plate to flatten the elastic sheet and embed the engaging plate and the elastic sheet into the engaging groove.

[0012] Preferably, the interlocking plate and the elastic sheet are interlocked with the interlocking groove, the sealing block first contacts the interlocking plate, and gradually pushes the interlocking plate to flatten the elastic sheet and embed the interlocking plate and the elastic sheet into the interlocking groove.

[0013] Preferably, the push rod passes through the positioning plate and is slidably connected. When the threaded rod rotates, the sealing block does not rotate with it, but gradually pushes the support rod into the fixed plate, and the sealing block is gradually inserted into the groove for sealing, while the telescopic spring is compressed.

[0014] Preferably, a support rod is fixedly connected to one side of the sealing block close to the fixed plate, the support rod passes through the fixed plate and is slidably connected, and a telescopic spring is fixedly connected between the sealing block and the fixed plate. When the wheel hub is in use, the mounting hole on the surface of the wheel hub body is connected to the vehicle drive shaft through bolts, and then the threaded rod is rotated. Since the support rod passes through the fixed plate and is slidably connected, the support rod will limit the sealing block.

[0015] Compared with the prior art, the utility model provides a wheel hub with positioning and adjustment function, which has the following beneficial effects:

[0016] The wheel hub with positioning and adjustment function, when the sealing block is gradually inserted into the groove, the sealing block will first resist the engaging plate, and gradually pushing the engaging plate will flatten the elastic sheet, and make the engaging plate and the elastic sheet embedded in the engaging groove, and gradually push the push rod when the elastic sheet is flattened, and when the engaging plate, the elastic sheet and the engaging groove are completely engaged, the elastic sheet will push the push rod to the maximum distance, and then the push rod will push the sealing plate to block the round hole, so that the installed bolts or nuts are sealed on the inner side of the sealing plate, so as to prevent some stones or foreign objects from getting stuck in the mounting hole of the wheel hub body when the vehicle is driving, which will cause inconvenience in replacing and maintaining tires, and even increase the loss of the wheel hub, and the sealing degree of the sealing plate can be adjusted by adjusting the threaded rod, which is convenient and quick.
