Description

Shock absorber convenient to install

Technical Field

The invention relates to a shock absorber, in particular to a shock absorber convenient to mount.

Background

In some mechanical equipment, two parts need to be connected through pipelines and are also connected in a rigid manner, for example, between oil tanks, between an oil tank and a pipeline, between a water tank and a pipeline, the two parts are directly connected through hard pipes at present, however, after the two parts or one part is connected, because a fixing part is used for a long time to generate looseness, a movable gap is generated, a rigid connection point is easy to damage in vibration and is not easy to replace, and technical updating is still required to be solved.

Disclosure of Invention

In order to solve the above problems, the present invention provides a shock absorber which is easy to install.

The technical scheme adopted by the invention is as follows: the utility model provides a bumper shock absorber convenient to installation, its characterized in that includes the core pipe, the guide pin bushing divide into guide pin bushing and lower guide pin bushing, go up guide pin bushing and lower guide pin bushing clearance fit on the core pipe, the upper end of going up the guide pin bushing is connected with outside outstanding last clamping ring, the lower extreme of lower guide pin bushing is connected with outside outstanding lower clamping ring, go up and be equipped with interior compression spring and the outer compression spring coaxial with the core pipe between clamping ring and the lower clamping ring, the spiral opposite direction of interior compression spring and outer compression spring, there is the hollow tube at the core pipe both ends through threaded connection respectively, the hollow tube outer end is connected with the annular preforming of pressing on the clamping ring inner edge, it is connected with the ring flange respectively to go up clamping ring and lower clamping ring, the ring flange is connected.

Further, go up the clamping ring and all be equipped with concentric interior annular groove and outer annular groove down on the clamping ring opposite face, interior annular groove and outer annular groove coincide with two ends of interior compression spring and outer compression spring respectively.

Furthermore, a groove is formed in the outer end face of the pressing ring, an annular rubber mat is arranged in the groove, and the guide pipe is opposite to the rubber mat body.

When the connecting device is used, the two flange plates are respectively connected with two parts to be connected through the connecting threads at the outer ends of the circular tubes, the upper pressing ring and the lower pressing ring are pressed during installation, the inner compression spring and the outer compression spring are compressed, the two flange plates can be easily placed between the two flange plates, the installation is convenient, when the connected parts are loosened to generate vibration, the stress can be transmitted to the compression springs through the pressing rings to absorb and release the stress, the service life is prolonged, the spiral directions of the inner compression spring and the outer compression spring are opposite, and the torsion generated by compression release can be reduced.

Detailed Description

The embodiment of the invention is shown in figures 1 and 2, the damper convenient for installation is provided with a core tube 1 and a guide sleeve, the round tube is a hollow round tube, the guide sleeve is divided into an upper guide sleeve 2 and a lower guide sleeve 3, the upper guide sleeve and the lower guide sleeve are in clearance fit on the core tube and can freely move up and down and keep good air tightness, the upper end of the upper guide sleeve is connected with an upper press ring 4 protruding outwards, the lower end of the lower guide sleeve is connected with a lower press ring 5 protruding outwards, an inner compression spring 6 and an outer compression spring 7 coaxial with the core tube are arranged between the upper press ring and the lower press ring, the opposite surfaces of the upper press ring and the lower press ring are respectively provided with an inner annular groove and an outer annular groove which are concentric, the inner annular groove and the outer annular groove are respectively inosculated with two ends of the inner compression spring and the outer compression spring, the stable support is not displaced, the spiral directions of the, can reduce the torsion that compression release produced, there is hollow tube 8 at the core pipe both ends through threaded connection respectively, the hollow tube outer end is connected with the annular preforming 9 of pressure on the clamping ring inner edge, go up the clamping ring and be connected with ring flange 10 respectively with lower clamping ring, the ring flange is connected with pipe 11, provide annular preforming activity space, the pipe outer end is equipped with end cover 12, be connected with pipe 13 on the end cover, through hollow part UNICOM between two pipes, the pipe outer end is equipped with connecting thread 14, be equipped with the recess on the outer terminal surface of clamping ring, be equipped with annular cushion in the recess, the pipe is relative with the cushion body, can seal the pipe port through annular cushion when being.

In summary, the present invention is only a preferred embodiment, and all equivalent modifications and additions made by the present application are considered to be within the technical scope of the present invention.
