Abstract

The utility model discloses a human engineering damping handle. The human engineering damping handle comprises a handle body and a connecting rod. Grooves suitable for placement of fingers are formed in the outer surface of the handle body, and the handle body and the connecting rod are connected through a damping connecting part. When an operator holds the handle body, the fingers are placed in the grooves, the design accords with the human engineering, and thus fatigue is reduced as much as possible. Moreover, after shake generated by an electric tool is absorbed by the damping connecting part, the damping effect is achieved, and thus injuries to the human body caused by the shaking are lessened. The human engineering damping handle can replace a traditional electric tool handle, shake can be reduced greatly, and fatigue of the operator caused by long-term operation can be relieved.

Description

A kind of ergonomics damping handle

Technical field

The utility model relates to a kind of parts of electric tool, specifically relates to a kind of ergonomics damping handle of electric tool.

Background technology

In existing production operation; often can use the electric tools such as electric angle grinder, electric drill, electric hammer, electric impact drill; the motor of these electric tools is when high speed operation; can produce great seismism; current various hand held electric tools both domestic and external, its handle and electric tool body mostly are rigid connection structure, make operator's hand and health obviously feel strenuous vibration; time slightly length will make operator not feel well, thereby human body is worked the mischief.In order to reduce vibrations, what have adheres at handle outer surface the sheath that a vibration-absorptive material is made, to realize local damping, but this mode damping effect is poor, also have by changing the internal structure of handle and realize damping object, if China national Department of Intellectual Property is in the utility model patent of the damping handle of on June 26th, 1991 bulletin, notification number is CN2079557U, it can reach certain cushioning effect, but its inside connects by spring, under the environment of electric tool strenuous vibration, handle is loosening distortion easily, stable not.Except reducing vibrations, if can design the handle that meets ergonomics, will further alleviate the fatigue of operator's long period of operation.

Summary of the invention

Technical problem to be solved in the utility model is just to provide a kind of ergonomics damping handle, can replace traditional electric tool handle, can greatly reduce vibrations, and the fatigue of alleviating operator's long period of operation.
