Problems solved by technology

The shock absorbing spring can filter the vibration, but the spring itself will reciprocate, causing the spring to be fatigued and damaged. The existing spring shock absorber needs to be removed for replacement or repair after the spring is damaged, which will bring about the disassembly of the equipment. In many cases, this kind of disassembly is not carried out in the manufacturer's assembly environment, which will lead to invisible damage to the equipment, and disassembly and installation take a long time

Embodiment 1

[0014] A double-rod tension spring shock absorber, comprising two guide shafts 1, two guide sleeves 2 sleeved on the guide shafts 1, several tension springs 3 installed between the two guide sleeves 2, two Two connecting bushings 4 are respectively mounted on one end of two guide shafts 1 on different sides, and two locking nuts 5 are installed on the corresponding other ends of the two guiding shafts 1, on the side of the guide sleeve plate 2 close to the locking nuts 5 A limit hole is set, and a limit bolt is installed in the limit hole, which is used to fix the guide sleeve plate 2 and the guide shaft 1 at the end of the locking nut.

[0015] Using the tension spring 3, when the connection shaft sleeve 4 transmits the force to the two guide shafts 1, since the other end of the guide shaft is locked by the lock nut, the guide sleeve plate close to the lock nut is locked by the limit bolt fixed, so that the two guide sleeves are pulled apart in two opposite directions along t...

Embodiment 2

[0017] As an optimized design of Embodiment 1, several hooks 6 are arranged on the guide sleeve 2 , and the tension spring 3 is sleeved on the hooks 6 .

[0018] The hooks 6 are evenly distributed along the edge of the guide sleeve 2 .

[0019] The materials and dimensions of several tension springs 3 are the same.

[0020] The material and size of the two guide sleeves 2 are the same, and the two guide shafts 1 have the same radius and the same material.

[0021] Through the above-mentioned embodiments, it can be seen that the present invention realizes shock absorption through the parallel connection of multiple springs and double connecting shafts and double guide sleeves. The stiffness coefficient of a single spring is small and the shock absorption effect is good. When a single spring is damaged , simply remove from the hook to replace without disassembling the entire shock absorber.

Abstract

The invention discloses a double-rod tension spring damper comprising two guiding shafts, two guiding sleeve plates connected to the guiding shafts in a sleeving manner and a plurality of tension springs installed between the two guiding sleeve plates. Two connecting shaft sleeves are installed at the ends of the different sides of the two guiding shafts, two locking nuts are mounted on the othercorresponding ends of the two guiding shafts, limiting holes are formed in the sides, close to the locking nuts, of the guiding sleeve plates, and limit bolts are installed in the limiting holes to beused for fixing the guide sleeve plates to the locking nut ends of the guide shafts. According to the double-rod tension spring damper, damping is achieved through double connecting shafts and the double guiding sleeve plates by means of multiple-spring parallel connection, the single springs have small stiffness coefficient, the damping effect is good, only the single springs need to be taken down from the hook when the single springs are damaged, and disassembling of the overall damper is not needed.

Description

technical field [0001] The invention relates to a spring shock absorber, in particular to a double-rod extension spring shock absorber. Background technique [0002] The spring shock absorber absorbs shock through the spring and is often used to control the continuous fluid vibration disturbance. The shock absorbing spring can filter the vibration, but the spring itself will reciprocate, causing the spring to be fatigued and damaged. The existing spring shock absorber needs to be removed for replacement or repair after the spring is damaged, which will bring about the disassembly of the equipment. In many cases, this kind of disassembly is not carried out in the manufacturer's assembly environment, which will lead to invisible damage to the equipment, and disassembly and installation take a long time. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide a double-rod tension spring shock absorber whi...
