Anti-shear spring shock absorber

Abstract

The invention discloses an anti-shear spring shock absorber, which comprises a spring body, an upper cover, a lower cover, a bottom plate, a limiting plate, a vertical plate, and a positioning bolt. The lower surface of the lower cover is fixed on the center of the bottom plate by bolts. There are installation gaps on the left and right sides of the bottom plate, and the bottom plate can be locked on the installation surface through the installation gaps; there are two mounting holes symmetrical along the center of the spring body on the vertical plate; there are two positioning bolts, passing through the vertical plate The mounting holes on the spring body are locked by nuts, and the positioning bolts are located on both sides of the spring body, and bushes are sleeved on the outside. The top of the upper cover and the limiting plate are locked by the locking screw. The left and right sides of the limiting plate are folded down and have curling edges. The curling is sleeved on the bushing. The limiting plate can move up and down and is limited left and right The curling of the bit plate is blocked, and the front and rear are blocked by the friction of the bushing and the vertical plate. The structure of the present invention is simpler, saves cost, and improves the anti-shear force effect of the spring damper.

Description

technical field [0001] The invention belongs to the field of spring shock absorbers, in particular to an anti-shear spring shock absorber. Background technique [0002] Spring shock absorbers are widely used in air conditioners, automobiles, thermal power plants, chemical plants, and steel plants, and can effectively control vibrations and swings of various frequencies. Ordinary spring dampers are only aimed at damping vibration in the vertical direction, while in mobile and transportation equipment, or areas where earthquakes often occur, the spring damper will be subjected to shear force, or lateral force, causing the spring to absorb vibration The horizontal bearing capacity of the device is poor, and there are potential safety hazards. Conventional anti-shear spring shock absorbers include JM3 type, which uses columns on both sides of the spring for lateral blocking; also includes GXSYM type, which uses a box-type structure. Others include mounting bolts on both sides,...

AI Technical Summary

Problems solved by technology

[0003] 1. The cost is high, and more steel plates need to be installed;

[0004] 2. The installation is complicated, and the balance on both sides needs to be adjusted, and sometimes the spring shock absorber needs to be lifted when installing up and down;

[0005] 3. Some products have poor anti-shear force effect, and the contact parts are small, easy to fall off or torn off when subjected to large lateral force
