Detailed Description
As shown in fig. 1 and 2, the noiseless tension spring balancer comprises a balancer body 1, wherein a safety pin 2 is arranged in the balancer body 1, a damper 3 is vertically arranged on the safety pin 2, a safety pin 5 is arranged on a piston rod head of the damper 3, and a damping assembly 4 is arranged between the safety pin 5 and the safety pin 2.
In practical application, the braking performance between the safety pin 5 and the safety pin 2 is enhanced through the damper 3 and the shock absorption assembly 4, the tension spring is prevented from being broken, the safety pin 5 and the safety pin 2 are collided with each other to generate noise, the safety of equipment is improved, and workers and the safety of the equipment are protected; the utility model discloses prevent that the extension spring from breaking, the noise that produces is strikeed each other between safety catch 5 and the safety catch 2, protection staff and equipment safety.
As shown in fig. 1 and fig. 2, the damping assembly 4 includes a spring 41 and an adjusting nut 42, the spring 41 is sleeved on the damper 3, the adjusting nut 42 is rotatably connected to a rod head of a piston rod of the damper 3 in a connecting manner, one end of the spring 41 is fixed on the safety pin 2, and the other end of the spring 41 is fixedly connected to the adjusting nut 42; in this embodiment, the tension spring is prevented from being suddenly broken by the buffering force of the damper 3, and the braking performance between the safety pin 5 and the safety pin 2 is enhanced by adjusting the elastic height of the fixed height adjusting spring 41 of the adjusting nut 42 on the piston rod of the damper 3, so that the tension spring is prevented from being broken and the safety pin 5 and the safety pin 2 are prevented from colliding with each other to generate noise.
As shown in fig. 2 and 3, the safety pin 5 includes a connecting seat 51 and a bracket 52, a detent 53 is provided on the bracket 52, and the detent 53 is fixedly connected to the balancer body 1 through a jackscrew 54; in this embodiment, the jack 54 passes through the balancer body 1 and the stopper 53 to clamp the shear pin 5 to the balancer body 1, thereby enhancing the braking performance between the shear pin 5 and the shear pin 2.
