Preferably, the working cylinder is fixedly connected with a connecting rod, a dust cover and a dust cover are arranged on the outer side of the connecting rod, and a hanging ring is further arranged at the tail end of the connecting rod.
Preferably, the cover bowl is welded and fixed with the shell of the oil storage cylinder assembly.
Compared with the prior art, the utility model has the beneficial effects that:
according to the scheme, the oil storage cylinder assembly, the working cylinder and the guide device form a first seal after being turned over by the plate type oil seal, the cover bowl, the full-rubber oil seal, the gasket and the connecting rod of the spring provide a second seal, and the second seal structure of the shock absorber can enable the full-rubber oil seal to realize sealing after the plate type oil seal is aged, so that the sealing performance of the shock absorber is improved, the service life of the shock absorber is prolonged, and the shock absorber has a better use effect.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
In the figure: 1. an oil storage cylinder assembly; 2. a working cylinder; 3. a guide; 4. plate type oil seal; 5. a spring; 6. a gasket; 7. full-rubber oil seal; 8. a bowl cover; 9. a connecting rod; 10. a dust cover; 11. a dust cover; 12. and (5) hanging rings.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1, a shock absorber with high tightness comprises an oil storage cylinder assembly 1 and a working cylinder 2, wherein the working cylinder 2 is arranged in an inner cavity of the oil storage cylinder assembly 1, a guide 3 is arranged at the rear end of the working cylinder 2, a plate-type oil seal 4 is arranged at the rear end of the guide 3, a gasket 6 and a full-rubber oil seal 7 are arranged at the rear end of the plate-type oil seal 4, a spring 5 is further arranged between the plate-type oil seal 4 and the gasket 6, two ends of the spring 5 respectively abut against the plate-type oil seal 4 and the gasket 6, a cover bowl 8 is arranged at the rear end of the full-rubber oil seal 7, and the full-rubber oil seal 7 is packaged through the cover bowl 8.
Aiming at the problems that after the conventional shock absorber is used for a long time, the plate type oil seal 4 is aged, and the shock absorber is poor in sealing and leaks oil, the oil storage cylinder assembly 1, the working cylinder 2 and the guide 3 form a first seal after being turned up through the plate type oil seal 4, meanwhile, the gasket 6, the full-rubber oil seal 7 and the cover bowl 8 are pressed and tightly pressed through the elastic force of the spring 5, the sealing of the outer side is realized by the encapsulation of the cover bowl 8 and the oil storage cylinder assembly 1, and the sealing of the inner side is realized by the full-rubber oil seal 7 matched with the connecting rod 9, so that a second seal is provided;
after the plate-type oil seal 4 is aged, the two sealing structures of the shock absorber can be still sealed by the full-rubber oil seal 7, so that the sealing performance of the shock absorber is improved, the service life of the shock absorber is prolonged, and the shock absorber has a better use effect.
