Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a high-durability automobile shock-absorbing and dust-proof rubber sleeve. Background Art

[0002] There are various kinds of auto parts. Shock absorbers are important parts in car use and are also very fragile parts. They are used to suppress the shock when the spring rebounds after absorbing shock and the impact from the road. In order to accelerate the attenuation of the vibration of the frame and body and improve the driving smoothness of the car, the connection between the cylinder and the piston rod on the car shock absorber needs to be treated with dust-proof rubber sleeves for dust-proof treatment. Otherwise, the oil in the cylinder will be contaminated with dust, affecting the continuous extension and retraction of the piston rod, making the shock absorber unable to be in a good working condition. The current dust-proof rubber sleeves are inconvenient to install and the installation is cumbersome. The sealing structure is simple and the sealing effect is poor, which leads to dust intrusion and affects normal work. In view of this, in-depth research was conducted on the above problems, and this case was created. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-6 A high-durability automobile shock-absorbing and dust-proof rubber sleeve includes a cylinder body 1, a rubber sleeve body 7 and an elastic sealing ring 16. The piston rod 6 is connected to the top of the cylinder body 1. A fixing ring 2 is installed on the outer side of the cylinder body 1 and the top of the piston rod 6, and a locking sleeve 8 is installed on the outer wall of the fixing ring 2. The rubber sleeve body 7 is connected between one end of the fixing ring 2. The outer wall of the piston rod 6 below the fixing ring 2 is connected to a positioning plate 3. The outer walls of the cylinder body 1 and one end of the piston rod 6 are connected with a convex edge 9. The outer walls of the cylinder body 1 and one end of the piston rod 6 are installed with an elastic sealing ring 16. The outer wall of the rubber sleeve body 7 is coated with a Teflon PTFE wear-resistant layer 18.

[0023] The inner wall of the locking sleeve 8 is provided with an internal thread, and the outer wall of the fixing ring 2 is provided with an external thread, forming a threaded connection structure between the locking sleeve 8 and the fixing ring 2;

[0024] The outer side of the fixed ring 2 is evenly installed with movable rods 10, and one end of the movable rods 10 extends to the inner side of the fixed ring 2. One end of the movable rods 10 is connected to a locking block 5. The outer walls of the cylinder 1 and the piston rod 6 are provided with a locking groove 4 that matches the locking block 5.

[0025] A return spring 11 is installed on the outer side of the movable rod 10 on the outer wall of the fixing ring 2, and the other end of the movable rod 10 is connected to a connecting plate 12;

[0026] Specifically, such as Figure 1 、 Figure 2 and Figure 3As shown, when using this structure, the fixing rings 2 at both ends of the rubber sleeve body 7 are inserted from the top of the piston rod 6, the lower fixing ring 2 is positioned above the cylinder body 1, and the upper fixing ring 2 is positioned on the outside above the piston rod 6 through the positioning plate 3. Then the locking sleeve 8 is rotated and the threads are engaged to move the locking sleeve 8 to one end so that the connecting plate 12 is squeezed inside. At the same time, the movable rod 10 drives the locking block 5 to be stuck inward into the locking groove 4 of the cylinder body 1 and the piston rod 6, which is convenient for installing the rubber sleeve body 7.

[0027] Example 2: A rubber sealing gasket 14 is installed on one end of the elastic sealing ring 16 on the outer wall of the cylinder body 1 and the piston rod 6, and the outer wall of one end of the rubber sealing gasket 14 is evenly provided with grooves 15, and the grooves 15 are symmetrical with respect to the center point of the piston rod 6 and the cylinder body 1;

[0028] The outer wall of the flange 9 is evenly installed with threaded rods 13, and a threaded connection structure is formed between the threaded rods 13 and the flange 9;

[0029] One end of the threaded rod 13 is movably connected to a pressure block 17 through a bearing, and one end of the pressure block 17 extends to the inner side of the groove 15, and the bottom end of the pressure block 17 is fixedly connected to the inner wall of the groove 15;

[0030] Specifically, such as Figure 1 、 Figure 4 and Figure 5 As shown, when this structure is used, the seal between the fixing ring 2 and the cylinder body 1 and the piston rod 6 is achieved by the elastic sealing ring 16 and the rubber sealing gasket 14. By rotating the threaded rod 13 and engaging the threads, the threaded rod 13 drives the pressure block 17 to move downward, and the pressure block 17 squeezes the rubber sealing gasket 14 and the elastic sealing ring 16 downward. Due to the elasticity of the rubber sealing gasket 14 and the elastic sealing ring 16, the extrusion deformation of the rubber sealing gasket 14 and the elastic sealing ring 16 fills the small gaps, thereby improving the sealing performance.

[0031] Working principle: When using this device, first, the rubber sleeve body 7 is installed outside the connection between the cylinder body 1 and the piston rod 6 to achieve dustproofing of the connection. The Teflon PTFE wear-resistant layer 18 realizes the wear resistance and high temperature resistance of the rubber sleeve body 7, making the rubber sleeve body 7 highly durable.

[0032] Implementation steps for the first innovation point:

[0033] Step 1: Insert the fixing rings 2 at both ends of the rubber sleeve body 7 from the top of the piston rod 6, position the lower fixing ring 2 above the cylinder body 1, and position the upper fixing ring 2 on the outside above the piston rod 6 through the positioning plate 3;

[0034] Step 2: Then rotate the locking sleeve 8 and thread it to move the locking sleeve 8 to one end so that the connecting plate 12 is squeezed inside. At the same time, the movable rod 10 drives the locking block 5 to be clamped inward into the locking groove 4 of the cylinder body 1 and the piston rod 6, and the rubber sleeve body 7 is installed.

[0035] Implementation steps for the second innovation point:

[0036] Step 1: The elastic sealing ring 16 and the rubber sealing gasket 14 are used to achieve sealing between the fixing ring 2, the cylinder body 1 and the piston rod 6. By rotating the threaded rod 13 and engaging the threads, the threaded rod 13 drives the pressure block 17 to move downward;

[0037] Step 2: The rubber sealing gasket 14 and the elastic sealing ring 16 are squeezed downward by the pressing block 17. Through the elasticity of the rubber sealing gasket 14 and the elastic sealing ring 16, the rubber sealing gasket 14 and the elastic sealing ring 16 are squeezed and deformed to fill the small gaps, thereby improving the sealing performance.
