Problems solved by technology

At present, linear motion joints that are manually operated in the vertical direction generally adopt the method of pulling springs for gravity balance. However, the spring force will increase with the increase of the pulling distance, thereby increasing the operator's workload.

Abstract

The invention relates to a regulating mechanism for balancing gravity, two guide slots are fixed on a tail-end fixed frame, and same structures are arranged on two sides of a straight-line guide rod and symmetric to an axial line of the straight-line guide rod; regulating screws are arranged on the guide slots, and the regulating screws are connected with the guide slots through threads; and end surfaces of the regulating screws are bonded with the end surfaces of guide blocks, springs are arranged on axes of the guide blocks, the axes penetrate holes on a friction wheel fixed frame, two end surfaces of the springs are bonded with the guide blocks and the friction wheel fixed frame respectively, and four side surfaces of the friction wheel fixed frame are bonded with inner side surfaces of the guide blocks and the guide slots respectively. The regulating mechanism can regulate the radial displacement of the straight-line guide rod under the situation of not changing the friction forcefor balancing the gravity, and has the advantages of simple mechanism and convenient regulation.

Description

technical field [0001] The invention relates to a balance mechanism, in particular to an adjustment mechanism for balancing gravity. Background technique [0002] At present, for linear motion equipment that needs to be manually operated in the vertical direction, holding the operating arm for a long time will cause fatigue to the operator, thereby reducing operating efficiency and increasing potential operating risks. At present, linear motion joints that are manually operated in the vertical direction generally adopt the method of pulling springs for gravity balance. However, the spring force will increase with the increase of the pulling distance, thereby increasing the workload of the operator. Contents of the invention [0003] The purpose of the present invention is to overcome the above defects and provide an adjustment mechanism for balancing gravity, which has the characteristics of constant balance force, convenient size adjustment, and convenient adjustment of r...
