Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of guiders, in particular to a novel guider for a shock absorber. Background Art
[0002] Shock absorbers are used to suppress the vibration caused by the rebound of the spring after absorbing shock and the impact from the road. They are widely used in automobiles to accelerate the attenuation of frame and body vibrations to improve the driving smoothness of the car. When passing through uneven roads, although the shock-absorbing spring can filter out the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump.
[0003] With the rapid development of shock absorbers, the requirements for shock absorber guides are also increased. However, the existing shock absorber guides will cause wear to the sealing structure after long-term use of the piston connecting rod, resulting in a decrease in sealing. Failure to replace them in time will lead to poor sealing, while timely replacement is too frequent, affecting the normal use quality. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, such as: the existing shock absorber guide will cause wear to the sealing structure after the piston connecting rod is used for a long time, resulting in a decrease in sealing. If it is not replaced in time, it will lead to poor sealing. If it is replaced in time, it will be too frequent, affecting the normal use quality. A new guide for a shock absorber is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A new type of guide for a shock absorber comprises a guide body, an oil sealing chamber is arranged on the top of the guide body, a rubber oil seal groove is arranged on the upper surface of the oil sealing chamber, an oil hole is arranged on the inner surface of the rubber oil seal groove, a piston connecting rod mounting cylinder is arranged on the lower surface of the guide body, a threaded ring is threadedly connected on the outer surface of the piston connecting rod mounting cylinder, a first sealing ring is arranged on the lower surface of the piston connecting rod mounting cylinder, a second sealing ring is arranged on the outer surface of the first sealing ring, an extrusion ring located directly above the outer surface of the second sealing ring is fixedly connected to the lower surface of the threaded ring, and the inner and outer surfaces of the second sealing ring are both arc-shaped inclined surfaces.
[0007] Preferably, the inner diameter of the inner surface of the second sealing ring gradually increases from bottom to top, and the outer diameter of the outer surface of the second sealing ring gradually decreases from bottom to top.
[0008] Preferably, a reinforcement groove is provided on the outer surface of the piston-connecting rod mounting cylinder, a pushing screw is threadedly connected to the inner surface of the reinforcement groove via a connecting plate, one end of the pushing screw away from the center of the piston-connecting rod mounting cylinder is fixedly connected to a rotating disk, and one end of the pushing screw away from the rotating disk is rotatably connected to a sealing reinforcement plate via a connecting bearing seat, an oriented groove is provided on the inner surface of the reinforcement groove, and one side of the sealing reinforcement plate is slidably connected to the inner surface of the oriented groove via an oriented rod.
[0009] Preferably, an anti-skid groove is provided on a side of the rotating disk away from the pushing screw, and anti-skid patterns are provided on the inner surface of the anti-skid groove.

[0011] Preferably, the number of the reinforcement grooves is not less than five and is arranged in a circular array.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model lowers the position of the extrusion ring by rotating the threaded ring, and the lowered position of the extrusion ring effectively squeezes the outer surface of the second sealing ring. The second sealing ring is squeezed to perform a secondary seal on the contact position of the piston connecting rod. By setting the inner surface of the second sealing ring as an inclined surface, it effectively fills the interference fit at the connection between the piston and the connecting rod, so that the sealing structure can still ensure the sealing performance after long-term wear, thereby achieving the effect of improving the working quality of the guide. The rotation of the rotating disk is controlled by setting an anti-skid groove, and the rotation of the rotating disk effectively squeezes the sealing reinforcement plate toward the inner side of the piston connecting rod mounting tube, and then the sealing reinforcement plate and the installed piston connecting rod are close to the limit, thereby increasing the correlation and reducing the wear during the working process, thereby improving the working quality of the guide.
