Improved spring shock absorber

Abstract

The invention provides an improved spring shock absorber. The improved spring shock absorber comprises a mounting frame, a fixing plate and guide columns; two guide cylinders are arranged at the bottom of the mounting frame, and the guide cylinders are connected with the mounting frame through welding; the two ends of the fixing plate are provided with the guide columns; and the fixing plate is connected with the mounting frame through the guide columns and the guide cylinders. An upper gland and a lower gland are fixedly connected with the fixing plate and the mounting frame respectively, anda spring is arranged between the upper gland and the lower gland. The spring sleeves the outer side of a screw rod, the lower end of the screw rod penetrates the lower gland, and the mounting frame is connected with an adjusting bolt. The upper end of the screw rod is provided with a locking bolt, and the screw rod penetrates the upper gland and is connected with the fixing plate and the lockingbolt through threads. By improving the improved spring shock absorber, the improved spring shock absorber has the advantages of being simple in structure, convenient to install and use, good in damping effect, reliable in shock absorption and capable of prolonging the service life, so that the problems and deficiencies of an existing devices are effectively solved.

Description

technical field [0001] The present invention relates to the technical field of shock absorbers, and more specifically, relates to an improved spring shock absorber. Background technique [0002] During the overhead installation of pipelines for air conditioners, exhaust fans and other equipment, the pipeline support needs to be hoisted to the wall. In order to reduce the vibration of the equipment during operation, spring shock absorbers are usually installed on the lifting rod. [0003] The Chinese patent with the notification number CN202868082U discloses a pipeline hoisting damping spring shock absorber, including a housing, a lifting ring, a positioning plate, a damping sleeve, a spring, a backing plate and a pull rod. The lifting ring is installed on the top of the housing, and the positioning plate, damping The sleeve, spring and backing plate are all placed in the shell, the backing plate is placed on the bottom of the shell, the positioning plate is placed on the upp...

Problems solved by technology

[0004] However, the above-mentioned patent has the following defects: 1. When the equipment vibrates, vertical vibration and lateral vibration will occur at the same time. Displacement affects the lateral stability of the shock absorber; 2. Once the end of the tie rod is displaced, it will affect the service life of the shell and the tie rod
