Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tires, and more specifically to a rim structure for connecting a pneumatic tire rim and a solid tire. Background Art
[0002] Pneumatic tires are tires filled with air. They are commonly used in vehicles such as cars and motorcycles to provide friction with the road surface and absorb vibration and impact during driving. While pneumatic tires bring comfort, they also bring new troubles such as inflation, tire repair, and tire blowout. Air molecules are very small and will escape from the gaps between rubber molecules, so pneumatic tires need to be inflated frequently. Pneumatic tires are easily punctured by sharp objects such as nails and glass, and sometimes they will blow out, which is very troublesome to repair.
[0003] Industrial vehicles such as forklifts, stackers, transporters, etc. Special vehicles: such as airport trailers, dock tractors, logistics transport vehicles, etc. These vehicles need to run continuously for a long time, and solid tires do not need to be inflated frequently, avoiding the problem of air leakage, greatly reducing the time and cost of maintenance.
[0004] Therefore, people often need to choose solid tires to replace pneumatic tires. However, most solid tire rims on the market are different from pneumatic tire rims. When replacing solid tires, the pneumatic tire rims and other related parts need to be replaced, which increases the cost of replacement. Utility Model Content
[0005] The utility model provides a rim structure for connecting the pneumatic tire rim and the solid tire. When the solid tire needs to be replaced, the pneumatic tire rim can be directly installed into the rim structure of the utility model after the pneumatic tire is removed, so that the tire can be replaced, which is very convenient and quick, can be reused, and reduces costs.
[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a rim structure for connecting a pneumatic tire rim and a solid tire, comprising a pneumatic tire rim and a connecting rim, wherein the pneumatic tire rim is installed in the connecting rim, and the connecting rim comprises a rim cylinder, a rim spoke plate is arranged on the rim cylinder, a side plate is arranged at one end of the rim cylinder, the side plate is connected to the rim spoke plate by bolts, and a pressure plate connected to the rim spoke plate by bolts is arranged at the other end of the rim cylinder; one end of the pneumatic tire rim has a protrusion, and the protrusion is pressed tightly against the side plate, and the other end of the pneumatic tire rim has an inclined conical surface, and the pressure plate presses on the inclined conical surface.
[0007] Preferably, a connecting plate is also provided on the rim spoke plate.
[0008] Preferably, the connecting plate and the side plate are connected by bolts.
[0009] Preferably, a gap is provided between the connecting plate and the side plate.
[0010] Preferably, the protrusion is installed in the gap between the connecting plate and the side plate.
[0011] Preferably, it is characterized in that the pressure plate has an inclined surface on the upper end surface and a flat surface on the lower end surface.
[0012] Preferably, the upper end of the pressure plate is also provided with a fixing plate which is bolted to the rim spoke plate.
[0013] Preferably, the distance between the fixing plate and the rim spoke plate is adjusted by bolts.
[0014] The beneficial effect of the utility model is that when the solid tire needs to be replaced, the pneumatic tire rim can be directly installed into the rim structure of the utility model after the pneumatic tire is removed. The upper part of the rim cylinder of the rim structure is bonded with a polyurethane solid tire core through a bonding process, thereby realizing the replacement of the tire, which is very convenient and quick, can be reused, and reduces costs.
[0015] The side plate is connected to the rim to prevent the inflatable rim from withdrawing, and the inclined surface on the upper end surface of the pressure plate and the bolt adjustment spacing between the fixing plate and the rim spoke plate are coordinated to ensure the cooperation between the connected rim and the inflatable rim to avoid brushing.
[0016] The wheel rim and the pneumatic tire rim are connected as a whole by bolts, which is convenient for disassembly. After disassembly, the pneumatic tire rim will not be affected in the continued use of the pneumatic tire. BRIEF DESCRIPTION OF THE DRAWINGS
[0017] Figure 1 It is a cross-sectional schematic diagram of an embodiment of the utility model;
[0018] Figure numerals: pneumatic tire rim-1, connecting rim-2, rim cylinder-3, rim spoke plate-4, side plate-5, pressure plate-6, protrusion-7, inclined cone surface-8, connecting plate-9, fixing plate-10. DETAILED DESCRIPTION
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] like Figure 1As shown, a rim structure for connecting a pneumatic tire rim and a solid tire can be directly installed into the rim structure of the utility model after the pneumatic tire is removed, including a pneumatic tire rim 1 and a connecting rim 2, wherein the pneumatic tire rim 1 is installed in the connecting rim 2, wherein the pneumatic tire rim 1 is the rim carried by the vehicle itself, and therefore the specific structure of the pneumatic tire rim 1 is not described in detail here.
[0021] Generally, a pneumatic tire rim 1 has a protrusion 7 at one end and an inclined conical surface 8 at the other end. The connected rim 2 includes a rim cylinder 3, a rim spoke plate 4 is arranged on the rim cylinder 3, a side plate 5 is arranged at one end of the rim cylinder 3, and the side plate 5 is connected to the rim spoke plate 4 by bolts. A pressure plate 6 connected to the rim spoke plate 4 by bolts is arranged at the other end of the rim cylinder 3; during installation, the protrusion 7 is pressed tightly against the side plate 5, and the pressure plate 6 is pressed against the inclined conical surface 8.
[0022] Specifically, a connecting plate 9 is also provided on the rim spoke plate 4, and the connecting plate 9 is connected to the side plate 5 by bolts, and a gap is provided between the connecting plate 9 and the side plate 5. After installation, the protrusion 7 is installed in the gap between the connecting plate 9 and the side plate 5, and the tightness of the bolts between the connecting plate 9 and the side plate 5 is adjusted to prevent the inflatable rim from falling out.
[0023] The pressure plate 6 has an inclined surface on the upper end face and a flat structure on the lower end face. A fixing plate 10 connected to the rim spoke plate 4 with bolts is also provided on the upper end of the pressure plate 6. The spacing between the fixing plate 10 and the rim spoke plate 4 is adjusted by bolts, so that the pressure plate 6 can be pushed to move left and right, thereby adjusting the tightness between the pressure plate 6 and the pneumatic tire rim 1, ensuring the fit between the connected rim and the pneumatic rim, and avoiding brushing.
[0024] At the same time, the connections between the rim and the two ends of the pneumatic tire rim are bolted, which is convenient for disassembly. Disassembly does not affect the continued use of the pneumatic tire rim for installing the pneumatic tire.
