[0002] A motorcycle is a two-wheeled or three-wheeled vehicle driven by a gasoline engine and steered by handlebars. It is light, flexible, and fast. It is widely used in patrolling, passenger and cargo transportation, and is also used as sports equipment. Generally speaking, motorcycles are divided into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes.

[0003] In the shock absorbers of the prior art, the sealing structure in the shock absorbers often cannot achieve reliable sealing. External impurities are often brought into the working cylinder body when the piston rod makes reciprocating motion, thereby causing wear of internal parts. Therefore, the existing shock absorbers will add a dust cover at the connection position, but the dust cover alone has poor protection effect. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: it includes a working cylinder body, a connecting rod is provided at the upper end of the working cylinder body; a dust cover is sleeved on the outer side of the connecting rod, and the dust cover is tightly connected to the working cylinder body; a hanging ring is provided at the lower end of the working cylinder body; connecting blocks are provided at the left and right ends of the outer side of the working cylinder body; a plunger tube is provided at the lower end of the connecting rod; an installation groove is opened at the upper end of the working cylinder body; a sealing assembly is provided in the installation groove of the working cylinder body; and a retaining spring is provided at the upper end of the sealing assembly.

[0006] Preferably, the sealing assembly includes a sealing ring body; a film is provided at the middle position of the upper and lower ends of the sealing ring body; and a cavity is formed between the film and the sealing ring body.

[0007] Preferably, an embedding groove is provided at the inner upper end of the working cylinder body, and the clamping spring is fixed in the embedding groove of the working cylinder body, and the clamping spring is tightly connected to the working cylinder body.

[0008] Preferably, the plunger tube passes through the working cylinder body, the sealing assembly and the dust cover, and the plunger tube is fixedly connected to the connecting rod.

[0009] Preferably, the lower end of the sealing assembly is tightly connected to a spring, and the lower end of the spring is tightly fitted with the interior of the working cylinder body, and the spring is a wave spring.

[0010] Preferably, an insertion groove is provided on one side adjacent to the upper end of the retaining spring, and the diameter of the insertion groove is 5 mm.

[0011] The utility model has the following beneficial effects:

[0012] Compared with the existing technology, this motorcycle shock absorber with a dustproof sealing structure has a sealing component and a dust cover.

[0020] Reference Figure 1-5The utility model provides a motorcycle shock absorber with a dustproof sealing structure: it includes a working cylinder body 1, a connecting rod 2 is provided at the upper end of the working cylinder body 1; a dust cover 3 is sleeved on the outside of the connecting rod 2, and the dust cover 3 is tightly connected to the working cylinder body 1; a hanging ring 4 is provided at the lower end of the working cylinder body 1; connecting blocks 5 are provided at the left and right ends of the outer side of the working cylinder body 1; a plunger tube 6 is provided at the lower end of the connecting rod 2; a mounting groove 7 is provided at the upper end of the working cylinder body 1; a sealing component 9 is provided in the mounting groove 7 of the working cylinder body 1; before using the device, the sealing component 9 is added to the inside of the working cylinder body 1 to improve the dustproof sealing effect of this position.

[0021] Among them, a retaining spring 10 is provided at the upper end of the sealing assembly 9. After the sealing assembly 9 is installed in the working cylinder body 1, the sealing assembly 9 inside the working cylinder body 1 is fixed by the retaining spring 10, thereby avoiding the problem of position displacement of the sealing assembly 9 due to long-term use.

[0022] It should be noted that, before the sealing assembly 9 is installed, oil is drained from the interior of the working cylinder body 1 to ensure smoothness of the plunger tube 6 and the connecting rod 2 when the working cylinder body 1 moves.

[0023] As a further implementation scheme of the above technical solution: Figure 3-5 As shown, the sealing component 9 includes a sealing ring body 901; a film 902 is provided at the middle position of the upper and lower ends of the sealing ring body 901; a cavity 903 is formed between the film 902 and the sealing ring body 901, and the sealing ring body 901 in the entire sealing component 9 is made of hard silicone, and the film 902 is embedded in the middle of the upper and lower ends of the sealing ring body 901. Therefore, when the upper and lower ends of the sealing ring body 901 are squeezed or impacted by external force, the film 902 is squeezed at the same time, causing the internal cavity 903 to be squeezed and deformed, and pushing the protruding position of the sealing ring body 901 outward, thereby avoiding the formation of a gap at the end of the sealing ring body 901 that contacts the connecting rod 2 and the working cylinder body 1.

[0024] As a further implementation scheme of the above technical solution: Figure 3-4As shown, an embedding groove 12 is provided at the inner upper end of the working cylinder body 1, and the circlip 10 is fixed in the embedding groove 12 provided in the working cylinder body 1. The circlip 10 is tightly connected to the working cylinder body 1. An insertion groove 11 is provided on the adjacent side of the upper end of the circlip 10, and the diameter of the insertion groove 11 is 5 mm. After the sealing ring body 901 is manually installed in the working cylinder body 1, the circlip 10 is placed on the upper end of the working cylinder body 1 and the duckbill pliers are manually inserted into the circlip 1 0, manually pinching reduces the space at both ends of the insertion groove 11 of the retaining spring 10, thereby reducing the outer diameter of the retaining spring 10, and after reducing it to be smaller than the mounting groove 7 of the working cylinder body 1, pushing it downward as a whole until the retaining spring 10 moves to the embedding groove 12 opened in the working cylinder body 1, the duckbill pliers can be loosened at this time, and the retaining spring 10 is reset while loosening, and the whole is stuck in the mounting groove 7, and the retaining spring 10 is fixed on the inside, and the sealing component 9 at the lower end can be limited.

[0025] As a further implementation plan of the above technical solution: the plunger tube 6 passes through the working cylinder body 1, the sealing assembly 9 and the dust cover 3, and the plunger tube 6 is fixedly connected to the connecting rod 2, and the lower end of the sealing assembly 9 is tightly connected to the spring 8, and the lower end of the spring 8 is tightly fitted with the inside of the working cylinder body 1. The spring 8 is a wave spring 8. When installing the sealing assembly 9, first place the wave spring 8 from top to bottom in the working cylinder body 1, and support the spring 8 by the limit of the mounting groove 7. Then insert the sealing ring body 901 in the sealing assembly 9 from top to bottom into the mounting groove 7 of the working cylinder body 1, and hammer it down with a leather hammer until the sealing ring body 901 contacts the spring 8 just installed inside, and then install the retaining ring 10, dust cover 3, connecting rod 2 and plunger tube 6, and the shock absorber can be installed as a whole, and then it can be installed on the motorcycle through the lifting ring 4 and the connecting block 5.
