Technical Field

[0001] The utility model relates to the field of tire assembly and disassembly, in particular to a device for conveniently assembling and disassembling a split wheel hub and a tire. Background Art

[0002] Tires and wheels are important components of a car. They each have different functions, but they work closely together to ensure the safety and stable driving of the vehicle. The tire is a ring-shaped elastic rubber product installed on a metal wheel hub and in direct contact with the road surface; the wheel hub is a barrel-shaped metal component with its inner profile supporting the tire and its center mounted on an axle. The split wheel hub is a special wheel hub design, which mainly consists of two parts: the rim and the spokes. These two parts can be connected together by bolts, clips or other means to form a complete wheel hub.

[0003] It is easier to change tires on vehicles with split wheels than on ordinary wheels. You only need to loosen the bolts between the rim and the spokes, and then use a crowbar or prying pieces to remove the tire from the rim. Therefore, most car owners will manually disassemble and assemble the tire themselves. However, using a crowbar can easily scratch or damage the surface of the wheel, and if the force of the crowbar is not well controlled, it can easily cause the wheel to deform. In addition, the crowbar may also puncture the tire, making it unusable. Furthermore, the use of a crowbar requires a lot of force. If the operation is improper or the crowbar suddenly slips and is thrown out, the operator may be injured. Utility Model Content

[0028] like Figure 2 and Figure 3 As shown, Figure 2 and Figure 3 This is a schematic diagram of installing a tire 7 on a wheel hub using the present application. The specific operation steps are as follows:

[0029] Preparatory steps: placing the rim 6 horizontally or horizontally, placing the tire 7 on the rim 6 and clamping one side of the tire 7 on the edge of the rim 6 to keep the tire 7 horizontal, and then installing the spoke 8 on the outer side of the tire 7 on the other side of the tire 7;

[0030] Installation steps: place the base 1 above the tire 7, make the telescopic rod 2 abut against the spoke 8, and support the base 1 with the telescopic rod 2, extend the screw 3 into the rim 6, so that the fixing part 4 is mounted on the center hole 61 of the rim 6, and the fixing part 4 abuts against the inner wall of the rim 6. After fixing the fixing part 4, apply a downward force to the spoke 8 and the tire 7 by twisting the rotating part 5. For example, the six telescopic rods 2 are distributed in a ring with equal distances, thereby ensuring that the tire 7 or the spoke 8 is evenly stressed and is mounted on the rim 6 in a relatively stable posture. After the tire 7 is completely placed on the rim 6, use bolts to connect the rim 6 and the spoke 8, reversely twist the rotating part 5 to loosen the telescopic rod 2 and the spoke 8, remove the device, and the installation is completed.

[0031] like Figure 4 and Figure 5 As shown, Figure 4 and Figure 5 Schematic diagram of removing a tire 7 from a wheel hub using the present application, and the specific operation steps are as follows:

[0032] Preparatory step: remove the bolts between the rim 6 and the spokes 8, and set the end surface of the rim 6 for mounting the spokes 8 downward;

[0033] Disassembly steps: place the base 1 above the tire 7, make the telescopic rod 2 abut against the tire 7, support the base 1 with the telescopic rod 2, extend the screw 3 into and pass through the rim 6, so that the fixing member 4 is erected on the outside of the center hole 61 of the rim 6, and the fixing member 4 abuts against the outside of the rim 6.

[0034] In some preferred embodiments, the bending angle of the telescopic rod 2 is set to 90° to ensure that the telescopic rod 2 applies a downward force to the spoke 8 or the tire 7 .

[0035] like Figure 1 As shown, in some embodiments, a groove 221 is provided at the end of the telescopic rod 2. It can be understood that according to the above installation steps, during use of the device, the support end 22 of the telescopic rod 2 will contact the surface of the spoke 8, and the spoke 8 usually forms an annular protrusion on its surface edge to strengthen the structure of the spoke 8 and make it more beautiful.

[0036] Corresponding to the above embodiment, Figure 5 As shown, the present application also provides some embodiments to facilitate the removal of the tire 7 from the rim 6. Specifically, the support end 22 of the telescopic rod 2 is detachably connected to a support leg kit 222, and the support leg kit 222 is in a T-shape, wherein the T-shaped support leg kit 222 includes a cross bar and a longitudinal bar perpendicular to each other, and the top end surface of the longitudinal bar is provided with a plug-in groove to install the support end 22 of the telescopic rod 2, and the cross bar is used to abut against the tire 7 to increase the stability of the telescopic rod 2 as a support leg.

[0037] In addition, Figure 1 and Figure 6 As shown, the present application can be used not only as a device for disassembling and assembling a split wheel hub and tire 7, but also as a vehicle rescue tool. Specifically, when the tire 7 of a vehicle engaged in outdoor activities accidentally sinks into mud or snow, the screw rod 3, the fixing member 4 and the rotating member 5 are detached from the base 1, and the telescopic rod 2 is stretched outward until the extended portion or the supporting end 22 of the telescopic rod 2 can be placed on the tread or crown of the tire 7, and then the telescopic rod 2 is pressed in reverse to make the extended portion or the supporting end 22 of the telescopic rod 2 close to the tread or crown of the tire 7. Preferably, in this embodiment, the base 1 and the rim 6 are also fixed by bolts. At this time, the telescopic rod 2 can increase the friction between the tire 7 and the mud or snow, thereby helping the vehicle to get out of trouble.

[0038] In some preferred embodiments, a plurality of second threaded holes equidistantly distributed along the length direction of the telescopic rod 2 are provided on the connecting end 21, and a third threaded hole connected to the groove 221 is provided on the base 1. Any one of the plurality of second threaded holes on the telescopic rod 2 is connected to the third threaded hole, and the telescopic rod 2 can be locked by installing bolts in the second threaded hole and the third threaded hole.
