Description

Technical Field

[0001] The utility model relates to the technical field of replacement, in particular to a rubber outer tire which is convenient for replacing the surface layer. Background Art

[0002] Existing tires are expensive, and due to long-term use of the tires, the wear caused by contact with the ground becomes more and more serious, and the grip is seriously insufficient. The only option is to replace the rubber outer tire, which is expensive.

[0003] According to a publicly disclosed rubber outer tire with an easy-to-replace surface layer (publication number: CN217073938U), in the above application, the fixing plate is fixed by the cooperation between the wheel axle and the nut, which has the function of facilitating the replacement of the surface layer. When the outer layer is severely worn, it is easy to replace the outer layer, thereby reducing the cost of changing the platform.

[0004] However, in actual use, although the outer layer of the above-mentioned device can be replaced, a large number of nuts need to be disassembled during replacement, which increases the disassembly and replacement time. In view of this, we propose a rubber outer tire that is easy to replace the surface layer. Utility Model Content

[0005] The utility model aims to provide a rubber outer tire with a convenient surface replacement, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rubber outer tire which is easy to replace the surface layer, comprising a surface tire, the outer surface of the surface tire being provided with a quick-release assembly, the outer surface of the surface tire being provided with a outer tire, the quick-release assembly comprising an inner circle wall, the outer surface of the surface tire being fixedly connected with the inner circle wall, the outer surface of the inner circle wall being provided with a No. 1 slot, the outer surface of the surface tire being fixedly connected with the outer circle wall, the outer surface of the inner circle wall being movably connected with a semi-arc metal plate, the outer surface of the semi-arc metal plate being provided with a slot hole, the outer surface of the slot hole being threadedly connected with a bolt, the outer surface of the semi-arc metal plate being fixedly connected with a No. 1 block, the outer surface of the No. 1 block being movably connected with the No. 1 slot, the outer surface of the semi-arc metal plate being movably connected with the outer tire, the outer surface of the outer tire being provided with a sidewall, and the outer surface of the sidewall being movably connected with the outer circle wall.

[0007] Preferably, the center line of the surface tire, the center line of the inner ring wall, the center line of the outer ring wall, the center line of the semi-arc metal plate, the center line of the outer tire, and the center line of the tire wall are all on the same center line, so that the whole can rotate stably.

[0008] Preferably, the size of the No. 1 card block is matched with the size of the No. 1 card slot, so that the No. 1 card slot can stably limit the range of movement of the No. 1 card block.

[0009] Preferably, there are several No. 1 clamping blocks, and the several No. 1 clamping blocks are arranged in a circular array on the outer surface of the semi-arc metal plate, so that the inner circle wall can be stably fixed to the semi-arc metal plate.

[0010] Preferably, a limiting component is provided on the outer surface of the semi-arc metal plate, and the limiting component includes a No. 2 clamping block. The outer surface of the semi-arc metal plate is fixedly connected with the No. 2 clamping block, and the outer surface of the sidewall is provided with a No. 2 clamping groove.

[0011] Preferably, the number of the second clamping blocks is several, and the several second clamping blocks are arranged in a circular array on the outer surface of the semi-arc metal plate, so that the semi-arc metal plate can be stably fixed to the tire wall.

[0012] Compared with the prior art, the utility model provides a rubber outer tire that is easy to replace the surface layer, and has the following beneficial effects:

[0013] 1. The rubber outer tire is easy to replace on the surface. When disassembling the surface tire, only two bolts on the two semi-arc metal plates need to be released, so that the two semi-arc metal plates are pulled out from between the tire wall and the inner rim wall, thereby increasing the activity space in the surface tire, so that the outer tire can move under the surface tire, and the outer tire can be quickly unloaded from the surface tire, thereby solving the problem of not needing to disassemble a large number of bolts when unloading the surface tire from the outer tire, so that the operation of quickly replacing the rubber tire on the surface can be realized.

[0014] 2. The surface rubber outer tire is easy to replace. When the surface tire is installed, the No. 1 clamping block on the two semi-arc metal plates will be restricted by the No. 1 clamping groove on the inner ring wall of the surface tire, and at the same time, the No. 2 clamping block on the semi-arc metal plate will be restricted by the No. 2 clamping groove in the sidewall of the outer tire. Finally, the two semi-arc metal plates play a limiting and synchronous role on the surface tire and the outer tire. When the surface tire rotates, the outer tire will also rotate synchronously, so that there will be no rotation difference between the two, which greatly eliminates the friction between the surface tire and the outer tire, increases the overall service life and ultimately ensures the stability in rotation operation.
