Description

Technical Field

[0001] The utility model relates to the technical field of wheel rims of rubber wheels for trolleys, in particular to a wheel rim of rubber wheels for trolleys which is easy to disassemble. Background Art

[0002] The wheelbarrows on construction sites are often used for short-distance horizontal transportation of construction materials, mortar and concrete on site due to their flexibility. These wheelbarrows generally use rubber tires.

[0003] The rims of the current rubber wheels of handcarts are all made of an integral structure during production, and the wheel hubs are mostly integral, that is, the spokes, the rims and the bearing seat are integrally connected. Replacing the tires installed on the handcart requires disassembling the entire wheel hub. Since the tires of the construction site handcarts are large in diameter and bear a heavy load, the wheel hub structure is strong, so the weight is large, and the overall disassembly is not easy. Therefore, it is necessary to design a trolley rubber wheel rim that is easy to disassemble to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a trolley rubber wheel rim which is easy to disassemble.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A trolley rubber wheel rim that is easy to disassemble comprises an outer hub, a connecting ring is installed on the inner wall of the outer hub through a plurality of outer spokes, a connecting mechanism for connecting a trolley connecting rod is arranged inside the connecting ring, the connecting mechanism comprises an inner hub arranged in the outer hub, a bearing seat is installed on the inner wall of the inner hub through a plurality of inner spokes, a plurality of bolts are arranged on the side wall of the connecting ring, nuts are arranged on the bolts, a positioning mechanism for positioning the inner hub is arranged on the side wall of the connecting ring, and a plurality of mounting seats are fixedly connected to the inner wall of the inner hub.

[0007] Preferably, the positioning mechanism comprises a plurality of second stops fixedly connected to the side wall of the inner hub, and the plurality of second stops are arranged at equal intervals.

[0008] Preferably, the side wall of the connecting ring is fixedly connected with a plurality of positioning blocks, and the side wall of the inner hub is fixedly connected with a plurality of first stop blocks that can cooperate with the positioning blocks.

[0009] Preferably, a mounting tube is fixedly connected to the side wall of the mounting seat, and a sealing cover is threadedly connected to the mounting tube.

[0010] Preferably, a mounting block is fixedly connected to the side wall of the inner hub, a fixing cylinder is fixedly connected to the lower end of the mounting block, and a threaded rod is connected to the inner thread of the fixing cylinder.

[0011] Preferably, a threaded seat is fixedly connected to the lower end of the threaded rod, a fixing column is fixedly connected to one of the side walls of the outer spokes, and a support seat is threadedly connected to the fixing column.

[0012] The utility model has the following beneficial effects:

[0013] 1. The device is provided with a connection mechanism, and the integral wheel hub is divided into an outer wheel hub and an inner wheel hub. After the inner wheel hub is installed on the trolley, when replacing the tire, only the outer wheel hub needs to be removed to replace the tire. Since the weight of the outer wheel hub is less than the weight of the integral wheel hub, it is more convenient to disassemble. At the same time, the light outer wheel hub also facilitates the removal of the tire, thereby improving the practicality of the device;

[0014] 2. The device is provided with a positioning mechanism. When the outer hub is installed, the connecting ring can be pushed onto the inner hub. Due to the blocking of the second stopper, the connecting ring can be prevented from being pushed too far, thus facilitating installation;

[0015] 3. The device is provided with a positioning block and a first stopper. By limiting the first stopper with the positioning block, it is unnecessary to manually observe the alignment of the mounting holes of the connecting ring and the inner hub with the naked eye, which further facilitates installation.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A trolley rubber wheel rim that is easy to disassemble comprises an outer hub 1, a connecting ring 3 is installed on the inner wall of the outer hub 1 through a plurality of outer spokes 2, a connecting mechanism for connecting a trolley connecting rod is arranged in the connecting ring 3, the connecting mechanism comprises an inner hub 4 arranged in the outer hub 1, a bearing seat 5 is installed on the inner wall of the inner hub 4 through a plurality of inner spokes 6, the bearing seat 5 is an accessory available on the existing market, a plurality of bolts 7 are arranged on the side wall of the connecting ring 3, nuts 11 are arranged on the bolts 7, and a plurality of mounting seats 10 are fixedly connected to the inner wall of the inner hub 4.

[0023] The side wall of the connecting ring 3 is provided with a positioning mechanism for positioning the inner hub 4. The positioning mechanism includes a plurality of second stoppers 14 fixedly connected to the side wall of the inner hub 4. The plurality of second stoppers 14 are arranged at equal intervals.

[0024] In the utility model, a plurality of positioning blocks 8 are fixedly connected to the side wall of the connecting ring 3, and a plurality of first stop blocks 9 which can cooperate with the positioning blocks 8 are fixedly connected to the side wall of the inner hub 4. When the first stop blocks 9 hit the positioning blocks 8, it indicates that the mounting holes of the connecting ring 3 and the inner hub 4 have been aligned, which is convenient for installation.

[0025] In the utility model, the side wall of the mounting seat 10 is fixedly connected with a mounting tube 13, and the mounting tube 13 is threadedly connected with a sealing cover 12, which can seal the connection between the bolt 7 and the nut 11 to prevent the wheelbarrow from sticking to cement and being easily twisted when used for a long time on the construction site.

[0026] In the utility model, a mounting block 15 is fixedly connected to the side wall of the inner wheel hub 4, a fixing cylinder 16 is fixedly connected to the lower end of the mounting block 15, a threaded rod 17 is connected to the inner thread of the fixing cylinder 16, and the threaded rod 17 can be screwed out to support the trolley, so that the outer wheel hub 1 will not fall to the ground after being removed, and the outer wheel hub 1 is convenient for reinstallation.

[0027] In the utility model, a threaded seat 18 is fixedly connected to the lower end of the threaded rod 17, a fixing column 20 is fixedly connected to the side wall of one of the outer spokes 2, and a support seat 19 is threadedly connected to the fixing column 20.
