Description

Shock absorber suitable for side-hung equipment

Technical Field

The utility model relates to a shock absorber, especially a shock absorber suitable for side hang equipment.

Background

At present, the shock absorber is more and more widely used and is mostly involved in land and seawater. Especially in submarine equipment, the guard plate is directly in rigid contact with the radar, mechanical noise is directly transmitted out, and the noise is large and the service life of a motor is influenced.

Disclosure of Invention

To exist not enough among the prior art, the utility model provides a shock absorber suitable for side-hang equipment realizes reducing mechanical noise's propagation to the shock attenuation of wall-hanging equipment. The utility model adopts the technical proposal that:

a shock absorber suitable for side hanging equipment comprises a shell and a central shaft, wherein the central shaft is arranged in the center of the shell, and the shell and the central shaft are fixed through rubber vulcanization.

Preferably, the shell comprises a flat base, a central sleeve is arranged in the middle of the base, and the central shaft and the central sleeve are arranged in a concentric manner.

Preferably, two groups of reinforcing ribs are symmetrically arranged between the base and the central sleeve.

Preferably, both sides edge all is equipped with the locating hole on the base.

Preferably, the top of the central sleeve is provided with a half-wrapping part extending inwards, and a part of the rubber top end is wrapped by the half-wrapping part.

Preferably, the bottom of the central shaft is provided with an extension part extending in the circumferential direction of the central shaft, the extension part is wrapped in rubber, and the distance between the outermost end of the extension part and the axis of the central shaft is greater than the distance between the innermost end of the half-wrapping part and the axis of the central shaft.

The utility model has the advantages that: adopt rubber vulcanization to become integrative shape between center pin and the casing for realize shock-absorbing function in the equipment of hanging on one's side, not only small light in weight, the shock attenuation is effectual moreover, the effectual propagation that reduces the noise.

In the figure: 1-shell, 2-rubber, 3-central shaft, 101-central sleeve, 102-reinforcing rib, 103-half-wrapped part, 104-positioning hole, 301-central hole and 302-extending part.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1-2, the utility model provides a shock absorber suitable for side hang equipment, including casing 1 and center shaft 3, center shaft 3 sets up at casing 1 positive center to it is fixed through the vulcanization of rubber 2 between casing 1 and the center shaft 3, and the vulcanization of rubber 2 combines center shaft 3 and casing 1 into an organic whole, has higher intensity, and the installation is simpler.

The shell 1 comprises a flat base, a central sleeve 101 is arranged in the middle of the base, the central shaft 3 and the central sleeve 101 are arranged concentrically, and the central sleeve 101 is used for placing the central shaft 3 and providing an installation space for the rubber 2.

Two groups of reinforcing ribs 102 are symmetrically arranged between the base and the central sleeve 101, and the reinforcing ribs 102 increase the strength of the shell 1 and reduce the deformation.

The edge of both sides on the base all is equipped with locating hole 104, and locating hole 104 is used for fixing the base on required mounted position.

The top of the central sleeve 101 is provided with a half-wrapped part 103 extending inwards, one part of the top end of the rubber 2 is wrapped by the half-wrapped part 103, and the half-wrapped part 103 wraps the top of the rubber 2, so that the connection stability between the rubber 2 and the central shaft 3 is improved.

The top surface of the rubber 2 coincides with the top surface of the half-wrapped part 103 and is lower than the highest surface of the central shaft 3, which facilitates the connection of the protruding part of the central shaft 3 with other parts.

The bottom of the central shaft 3 is provided with an extension part 302 extending towards the circumferential direction of the central shaft 3, the extension part 302 is wrapped in the rubber 2, the distance between the outermost end of the extension part 302 and the axis of the central shaft 3 is larger than the distance between the innermost end of the half-wrapping part 103 and the axis of the central shaft 3, the top of the central shaft 3 is provided with a central hole 301 for connecting the central shaft 3 with other components, the extension part 302 extends into the rubber 2 to further improve the installation stability of the central shaft 3, and the central hole 301 facilitates the connection of the central shaft 3 with other components.

The central shaft 3 and the shell 1 are both titanium alloy structures, and have light weight, small volume and good corrosion resistance when used in seawater.

The utility model is used for among the submarine equipment, use on the submarine backplate for keep apart outside motor, avoid the noise direct propagation, integral structure simple to operate, whole platykurtic is not only small and light in weight, and 2 deformations of rubber play the cushioning effect during the use, and casing 1 and center pin 3 direct contact not avoid the rigidity collision.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
