The utility model adopts the technical proposal that: the utility model provides a shock absorber, includes outer jar, suit working cylinder in the outer jar, fixes director and oil blanket, one end at outer jar and working cylinder top and passes director and oil blanket and stretch into piston rod, the piston of connection on the piston rod in the working cylinder and set up the bottom valve in the working cylinder bottom, still includes the buffering subassembly of suit on the piston rod, the buffering subassembly includes the lantern ring, elastic component and bearing ring, be equipped with the spring chamber on the lantern ring, the go-between of bearing ring stretches into the spring chamber, elastic component one end links firmly with the diapire in spring chamber, and the other end links firmly with the go-between, be equipped with the through-hole that is used for the medium oil to pass through on the lantern ring, leave the oily clearance between the outer wall of bearing ring and the working cylinder inner wall.

Furthermore, the outer wall of the lantern ring is attached to the inner wall of the working cylinder, and the outer wall of the lantern ring is of a wave structure.

Furthermore, an oil passing hole is formed in the guider, and an oil passing channel is formed between the outer cylinder and the working cylinder.

Further, the bottom of the outer cylinder is welded with a bottom cover.

Further, the pressure-bearing ring is made of elastic rubber.

The utility model has the advantages that: the utility model discloses a set up the buffering subassembly, the buffering subassembly has better elastic buffer effect through setting up the elastic component, not only can play fine limiting displacement, also can play better buffering shock attenuation effect simultaneously, when the protection subassembly can not damage because of the striking, realizes falling the purpose of making an uproar.

In addition to the above-described objects, features and advantages, the present invention has other objects, features and advantages.

The present invention will be described in further detail with reference to the drawings.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

The utility model provides a shock absorber.

In this embodiment, referring to fig. 1 and 2, this shock absorber, including outer cylinder 1, suit working cylinder 2 in the outer cylinder, fix director 3 and oil blanket 4 at outer cylinder and working cylinder top, one end passes director and oil blanket and stretches into piston rod 5 in the working cylinder, connect piston 6 on the piston rod and set up bottom valve 7 in the working cylinder bottom, still includes the buffering subassembly 8 of suit on the piston rod, buffering subassembly includes lantern ring 9, elastic component 10 and bearing ring 11, be equipped with spring chamber 12 on the lantern ring, the go-between 13 of bearing ring stretches into the spring chamber, elastic component one end links firmly with the diapire in spring chamber, and the other end links firmly with the go-between, be equipped with through-hole 14 that is used for medium oil to pass through on the lantern ring, leave oil clearance 15 between the outer wall of bearing ring and the working cylinder inner wall.
