[0031] Referring to Figures 1 to 9 , the present utility model provides an auxiliary installation assembly, including: an extrusion member 10 and a first annular member 20. The first annular member 20 and the extrusion member 10 are detachably connected. The first annular member 20 is used to abut against the axial end face of the tire 2; a support member 30 and a second annular member 40. The second annular member 40 and the support member 30 are detachably connected. The second annular member 40 is used to support the rim 1.

[0032] The auxiliary installation component of the present utility model includes an extrusion member 10, a first annular member 20, a support member 30, and a second annular member 40. The first annular member 20 is disposed at the end of the extrusion member 10 close to the tire, and the second annular member 40 is disposed at the end of the support member 30 close to the rim. By driving the first annular member 20 to move downward along the axial direction of the tire 2 through the extrusion member 10, the first annular member 20 presses the tire 2, so that the tire 2 is completely sleeved on the rim 1 to complete the installation. During this process, the support member 30 supports the rim through the second annular member 40. Since the first annular member 20 and the extrusion member 10 are detachably connected, and the second annular member 40 and the support member 30 are detachably connected, a first annular member 20 matching the specification of the tire can be manufactured according to the specifications of the actually installed tire and the rim, and a second annular member 40 matching the specification of the rim can be manufactured. Then, the new first annular member 20 and the new second annular member 40 are respectively installed on the extrusion member 10 and the support member 30, and the tire of the new specification can be successfully installed on the rim of the new specification. Since the structures of the first annular member 20 and the second annular member 40 are relatively simple and the manufacturing cost is low, under the condition of not needing to specially manufacture the support member 30 and the extrusion member 10, the auxiliary installation component of the present application can install tires of various specifications on the corresponding rims, thus solving the problem of high installation cost of solid tires in the prior art, reducing the storage space occupied by the support member 30 and the extrusion member 10, and reducing the difficulty of storing and handling the support member 30 and the extrusion member 10.

The diameter of the first extruding disc 11 is smaller than that of the second extruding disc 12. The first extruding disc 11 is arranged closer to the tire 2 relative to the second extruding disc 12. A first limiting circular groove 13 is formed in the first extruding disc 11.

[0041] Specifically, at least a part of the fourth annular portion 42 penetrates into the second limiting circular groove, so that the circumferential outer wall of the fourth annular portion 42 abuts against the circumferential inner wall of the second limiting circular groove, enabling the second limiting circular groove to limit the second annular member 40 and preventing the second annular member 40 from sliding relative to the rim 1 in the radial direction of the tire, thus ensuring the connection reliability between the rim 1 and the second annular member 40; by the axial end wall of the fourth annular portion 42 abutting against the bottom of the second limiting circular groove, the contact area between the second annular member 40 and the rim 1 is increased, further ensuring the support reliability of the second annular member 40 for the rim 1.

[0042] In this embodiment, the support member 30 includes a first support disk 31 and a second support disk 32 that are connected to each other. The first support disk 31 and the second support disk 32 are arranged opposite to each other in the axial direction of the tire 2. The central axes of the first support disk 31 and the second support disk 32 are both arranged to coincide with the central axis of the tire 2.

The first support disk 31 is arranged closer to the rim 1 than the second support disk 32, and the first support disk 31 is used for detachably connecting to the second annular member 40.

[0043] Specifically, the auxiliary installation assembly further includes an installation base plate. The second support disk 32 is arranged on the installation base plate. The first support disk 31 is used for connecting to the second annular member 40, enabling the support member 30 to support the rim 1 through the second annular member 40.

[0044] In this embodiment, a third limiting circular groove 33 is formed in the first support disk 31. The third annular portion 41 of the second annular member 40 penetrates into the third limiting circular groove 33, so that the circumferential outer wall of the third annular portion 41 abuts against the circumferential inner wall of the third limiting circular groove 33, and the axial end wall of the third annular portion 41 abuts against the bottom of the third limiting circular groove 33, enabling the second annular member 40 and the support member 30 to be detachably connected.

[0045] Specifically, by the third annular portion 41 of the second annular member 40 penetrating into the third limiting circular groove 33, the circumferential outer wall of the third annular portion 41 abuts against the circumferential inner wall of the third limiting circular groove 33, enabling the first support disk 31 to limit the second annular member 40 and preventing the second annular member 40 from sliding relative to the support member 30 in the radial direction of the tire 2, thus ensuring the connection reliability between the second annular member 40 and the support member 30.

[0046] During specific implementation, when the third annular portion 41 of the second annular member 40 penetrates into the third limiting circular groove 33, the axial end wall of the third annular portion 41 abuts against the groove bottom of the third limiting circular groove 33, and the axial end wall of the fourth annular portion 42 abuts against the axial end wall of the first support disk 31, increasing the contact area between the support member 30 and the second annular member 40, thereby ensuring the support reliability of the support member 30 for the second annular member 40.

The first annular member 20 is arranged at the end of the extrusion member 10 close to the tire, and the second annular member 40 is arranged at the end of the support member 30 close to the rim. By driving the first annular member 20 to move downward along the axial direction of the tire 2 through the extrusion member 10, the first annular member 20 presses the tire 2, so that the tire 2 is completely sleeved on the rim 1 to complete the installation.

Then, the new first annular member 20 and the new second annular member 40 are respectively installed on the extrusion member 10 and the support member 30, and the tire of the new specification can be successfully installed on the rim of the new specification. Since the structures of the first annular member 20 and the second annular member 40 are relatively simple and the manufacturing cost is low, without the need to specially manufacture the support member 30 and the extrusion member 10, the auxiliary installation component of the present application can install tires of various specifications on the corresponding rims, thereby solving the problem of high installation cost of solid tires in the prior art, reducing the storage space occupied by the support member 30 and the extrusion member 10, and reducing the difficulty of storing and handling the support member 30 and the extrusion member 10.
