Detailed Description

The present utility model will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.

The utility model is further described below with reference to the accompanying drawings,

as shown in fig. 1, the conventional general damper 5 is provided with a gland 4: the rubber dust cover 3 cannot be fixed only by the function of protecting the oil seal without being matched with the dust cover 3, so that the shock absorber 55 runs at risk of rod leakage. Therefore, the dust cover 3 for the shock absorber 55 is designed to be matched with the special-shaped gland 4, as shown in fig. 2-4, the gland 4 is arranged on the shock absorber 5 in a penetrating way and is fixed with one end of the shock absorber 5, a piston rod of the shock absorber 5 penetrates through the gland 4, the gland 4 is used for being matched with the dust cover 3, and the dust cover comprises a gland 4 body, and the gland 4 body is a cylindrical shell with one side open;

the cooperation hole 45, the cooperation hole 45 sets up the middle part at gland 4 body one end, the cooperation hole 45 is used for the passage of piston rod, and the setting of cooperation hole 45 has a spacing to the piston rod, guarantees that the piston rod stretches out or when contracting, can not produce radial displacement.

A fixing clip 42, wherein the fixing clip 42 is arranged on the outer edge of the gland 4 body far away from one end of the matching hole 45, the fixing clip 42 is obliquely arranged, and the fixing clip 42 is used for matching with the dust cover 3; when the size of the matching part of the gland 4 and the dust cover 3 is oversized, the shock absorber 5 cannot be matched in the later assembly; when the size of the matching position of the gland 4 and the dust cover 3 is too small, the shock absorber 5 cannot reach the design target in the operation process, and the overall performance of the product is affected, so that the diameter from the outermost edge of the fixing clamp 42 to the circle center of the body of the gland 4 is designed to be larger than 0.5cm of the dust cover, the size is optimal when the gland 4 and the dust cover 3 are matched for use, the assembly efficiency is improved, and the use precision is not affected.

The boss 44, the boss 44 sets up on the outer peripheral wall of gland 4 body near mating hole 45 one end, boss 44 is used for fixed gland 4 and bumper shock absorber 5 mutually, and boss 44 blocks with bumper shock absorber 5's outer peripheral wall mutually, guarantees the fixed firm between gland 4 and the bumper shock absorber 5.

The number of the fixing cards 42 is 3, the number of the bosses 44 is at least 3, and the bosses 44 protrude toward the axle center of the gland 4 body.

The gap groove 43 is arranged between two adjacent fixing cards 42, the fixing cards 42 and the gland 4 are connected into a whole, the boss 44 and the gland 4 are connected into a whole, and the fixing cards 42, the boss 44 and the gland 4 are connected into a whole, so that the structural strength of the gland 4 is improved, and the service life of the gland 4 is prolonged.

The gland 4 is an iron gland 4, the original gland 4 is made of plastic, but when the shock absorber 5 sprays paint, the plastic gland 4 can be deformed by heat or burst, and the original plastic gland 4 is changed into the iron gland 4, so that the problem is solved, and the strength of the gland 4 is improved.

The application principle of the utility model is as follows: when the shock absorber is used, the gland 4 is arranged on the shock absorber 5 in a penetrating mode, the piston rod passes through the matching hole 45, then the gland 4 is fixed with one end of the shock absorber 5 through the boss 44, after the fixation is completed, the dust cover 3 is sleeved, one end of the dust cover 3 is fixed with the front end of the piston rod, the other end of the dust cover 3 is fixed with the fixing clamp 42, the outermost edge of the fixing clamp 42 is wrapped by the dust cover 3, the dust cover 3 is clamped by the fixing clamp 42, the matching between the two is achieved, the effect of protecting an oil seal is achieved, abrasion of the dust cover 3, namely the body paint of the shock absorber 5, the bottom of the dust cover 3 and other parts can be prevented, and the problem of rod leakage during operation of the shock absorber 5 can be solved.
