Embodiment Construction

[0010] Specific embodiments of the present invention will be further described in detail below.

[0011] Such as figure 1 , figure 2 with image 3 As shown, a spring balancer according to the present invention includes a housing 10 , and a rotatable knob 12 is arranged inside the housing 10 . The rotating shaft of the knob 12 is wound around the coil spring 14 , and the fixed end of the coil spring 14 is fixed on the knob 12 . The free end of the coil spring 14 is connected with a suspension rope 16, and the free end of the suspension rope 16 stretches out of the shell 10. The free end of the suspension rope 16 is provided with a hook 18 .

[0012] When the spring balancer of the present invention is in use, the knob 12 can be rotated according to the weight of the suspended tool (not shown), thereby adjusting the torsion of the coil spring 14 so that it reaches a balanced state with the suspended tool. The spring balancer of the invention has the advantages of simple st...

Abstract

The invention discloses a spring balancing machine which comprises an outer shell. A rolling spring is arranged inside the outer shell. A fixed end of the rolling spring is connected with the outer shell. A free end of the rolling spring is connected with a suspension rope. A free end of the suspension rope extends out of the outer shell. The spring balancing machine is characterized in that a rotatable knob is arranged at a position, corresponding to the center of the rolling spring, of the outer shell, the rolling spring is wound on a rotating shaft of the knob, and the fixed end of the rolling spring is fixed on the knob. Torsion of the rolling spring can be manually adjusted by the spring balancing machine through the knob at will according to the weight of suspended objects and is enabled to be balance. The spring balancing machine has the advantages of being simple in structure, convenient to operate and the like.

Description

technical field [0001] The invention relates to a spring balancer. Background technique [0002] The spring balancer is an auxiliary tool used in conjunction with the operating tool. It uses the energy stored in the coil spring to suspend the operating tool. It has a basic requirement that the operating tool can be suspended at any position, so that the suspended operating tool is in a weightless state, thereby greatly reducing the labor intensity of the operator and improving labor productivity. Therefore, the spring balancer is an indispensable auxiliary tool in the factory. The current balancer basically cannot adjust the coil spring, which makes the force of the coil spring different when suspending tools with different weights. In order to ensure that the tool can stay in any position, other devices or mechanisms are usually required to assist. Contents of the invention [0003] The present invention provides a solution to the above problems, providing a spring bal...
