[0002] On chain-driven motorcycles, in order to protect the wheel hub and increase its service life, a buffer rubber block is generally set inside the wheel hub cover as a buffer. This buffer rubber block can gently transfer the power from the engine to the sprocket, thereby indirectly protecting the wheel hub.

[0003] However, common buffer rubber blocks are generally made of rubber material, which ages quickly and often shrinks due to aging, resulting in a gap that causes the sprocket to loosen. Therefore, the buffer rubber blocks need to be replaced regularly, and the frequent replacements increase the cost of using the vehicle.

[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0020] Please refer to Figure 1-Figure 4 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of a sprocket buffer body that is durable and reduces cost provided by the utility model; Figure 2 This is a schematic diagram of the formal cross-sectional structure of the utility model; Figure 3 It is a schematic diagram of the side cross-sectional structure of the interference strip and the arc-shaped sheet in the utility model; Figure 4 for Figure 3 The A part is shown as an enlarged schematic diagram. The durable and cost-saving sprocket buffer body comprises: a buffer rubber block 1 made of rubber material, and a V-shaped opening 2 and a through groove 3 are provided on the buffer rubber block 1. The through groove 3 is provided on both sides of the V-shaped opening 2, and an arc-shaped sheet 6 is provided in the V-shaped opening 2. The two sides of the arc-shaped sheet 6 extend into the two through grooves 3 respectively, and two abutment strips 8 are slidably sleeved on the arc-shaped sheet 6. The two sides of the two abutment strips 8 that are away from each other are in contact with the inner walls of the two sides of the V-shaped opening 2 respectively. By moving the abutment strips 8, the The side portion of the buffer rubber block 1 is deformed and stretched, thereby forcing it to fit with the side wall of the hub cover again, and a plurality of snap-in grooves 7 are provided on the arc-shaped sheet 6. The plurality of snap-in grooves 7 are divided into two groups, each group has three, and the two groups are used in conjunction with two interference strips 8 respectively. In order to relatively fix the interference strips 8 and the arc-shaped sheet 6, a plug-in mechanism is provided on the two interference strips 8, which are used to snap into the snap-in grooves 7 so that the interference strips 8 and the arc-shaped sheet 6 restrain each other to form a clamping effect.

[0021] In the above manner, in order to reliably fix the arc-shaped sheet 6 , a connecting piece 4 is fixedly installed on the bottom inner wall of the V-mouth 2 , and the connecting piece 4 is connected to the arc-shaped sheet 6 through a supporting column 5 .

[0022] In the above-mentioned plug-in mechanism, it includes two sliding rods 9 slidably installed on the same interference strip 8, and the same connecting strip 10 is fixedly installed at the same direction end of the two sliding rods 9. In the initial state, the connecting strip 10 is in contact with the interference strip 8, and an embedding head 11 is fixedly installed on one side of the connecting strip 10, one end of the embedding head 11 extends into the corresponding positioning groove 7, and the embedding head 11 is slidably connected to the interference strip 8, and a circular baffle 12 is fixedly installed at the other end of the two sliding rods 9. A spring 13 is sleeved on the two sliding rods 9, one end of the spring 13 is fixedly connected to the interference strip 8, and the other end is fixedly connected to the circular baffle 12. The spring 13 is in a stretched state in the initial state.

[0023] In the present method, in order to firmly clamp the embedding head 11 in the locking groove 7, a convex plate 14 is fixedly installed on the two interference strips 8, and bolts 15 are threadedly installed on the two convex plates 14. The ends of the two bolts 15 close to each other are fixedly installed with limiting heads 16. The two limiting heads 16 respectively interfere with the side of the two connecting strips 10 away from the interference strip 8. The limiting heads 16 form a blockage on the connecting strips 10 to prevent the spring 13 in the stretched state from pulling back, thereby ensuring the reliability of the insertion between the embedding head 11 and the locking groove 7.

[0024] In this embodiment, an arc groove is formed at the bottom of the buffer rubber block 1 , and the arc-shaped sheet 6 is coaxial with the arc groove, so that the abutment strip 8 can be pushed to both sides with the same axis as the buffer rubber block 1 .

[0025] The working principle of the sprocket buffer body provided by the utility model, which is durable and reduces cost, is as follows:

[0026] In the initial state, the four springs 13 are all in a stretched state;

[0027] During the use of the buffer rubber block 1, when the two sides thereof do not contact the side walls of the hub cover due to shrinkage, the two bolts 15 can be rotated first to bring the two limit heads 16 away from the corresponding connecting strips 10. At this time, the two connecting strips 10 are no longer blocked by external objects, and the stretched spring 13 will pull back, thereby pulling the two embedded heads 11 out of the corresponding locking grooves 7.

[0028] Then, push one of the resistance strips 8 toward one side to start pushing one side of the V-mouth 2. At this time, one side portion of the buffer rubber block 1 begins to deform and stretch until the side contacts a side wall of the hub cover. First, slightly adjust the position of the embedding head 11 to make it correspond to the nearest positioning groove 7, then push the corresponding connecting strip 10, and insert the corresponding embedding head 11 into the corresponding positioning groove 7. Then, turn the corresponding bolt 15 to re-engage the corresponding limit head 16 on the connecting strip 10 to limit it. Then, push another resistance strip 8 toward the other side in the same way as above, and finally make the other side of the buffer rubber block 1 deform and fit the side wall of the hub cover, so that the buffer rubber block 1 is utilized again.

[0029] Compared with the related art, the durable and cost-reducing sprocket buffer provided by the utility model has the following beneficial effects:

[0030] The utility model provides a durable and low-cost sprocket buffer body, which can push the two side parts of the buffer rubber block 1 to deform and stretch by setting two resistance strips 8 that can move to both sides, so that they can finally fit with the side wall of the wheel hub cover again, so that the sprocket can be buffered and protected again, thereby increasing the service life of a single buffer rubber block 1 and reducing the cost of using the vehicle.

[0031] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
