Abstract
The invention relates to a valve wrench. The valve wrench comprises a handle, a connection arm and a wrench head, wherein the wrench head comprises an acting force transmission portion and a clamping claw portion, the clamping claw portion is connected below the acting force transmission portion, the acting force transmission portion is an arched body, and the clamping claw portion is an arc body turned outwards. When the valve wrench is operated, the clamping claw portion is clamped between a center connection rod and an outer ring body of a valve, the acting force transmission portion transmits force to the clamping claw portion, the clamping claw portion is firmly clamped between the center connection rod and the outer ring body of the valve, and therefore the valve wrench effectively prevents slipping, and brings great convenience to operators.
Description
Technical field
The present invention relates to a kind of spanner, be specifically related to a kind of tap wrench.
Background technology
The industry such as current oil, petrochemical industry, chemical industry, metallurgy, electric power, water conservancy, urban construction, machinery, coal, food needs a large amount of pipeline valves to carry out controlling and operating, due to the flexibility of the economy of manually-operated gate, durability and manipulation, still adopted by most enterprises, these manually-operated gates depend merely on hand to rotate handwheel, are often difficult to open or close.Although there is the Simple spanner that " F " shape two tooth spanner or enterprise oneself make in the market, but lack non-skid feature, spanner is difficult to be fixed on fast on handwheel, makes troubles to operator, can not open rapidly or valve-off, even bring personal injury to operator under desperation.
Summary of the invention
The present invention seeks to provide a kind of tap wrench to overcome the deficiencies in the prior art, structure is simple, easy to operate, laborsaving.
For achieving the above object, the technical solution used in the present invention is: a kind of tap wrench, comprises handle, linking arm and spanner, and described spanner comprises force transmission portion and clamping claw; Described clamping claw is connected to the below in force transmission portion; Described force transmission portion is ogive; Described clamping claw is the arc body to turning up.
Improve further as the present invention, described handle is ring-shaped handle.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of tap wrench of the present invention program, during operation, clamping claw is stuck between the center connecting rod of valve and external rings body, when power being passed in force transmission portion clamping claw, clamping claw is firmly clamped between center connecting rod and external rings body, effectively prevent skidding, bring great convenience to operator.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of tap wrench of the present invention;
Wherein: 1, handle; 2, linking arm; 3, spanner; 4, force transmission portion; 5, claw is clamped; 6, center connecting rod; 7, external rings body.
detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1 is a kind of tap wrench of the present invention, comprises handle 1, linking arm 2 and spanner 3, and described spanner 3 comprises force transmission portion 4 and clamping claw 5; Described clamping claw 5 is connected to the below in force transmission portion 4; Described force transmission portion 4 is ogive, and in the middle part of ogive shape, empty body provides space for valve inner structure, avoids in use procedure, mutually disturbs with valve inner structure; Described clamping claw 5 is the arc body to turning up, and when operating, the clamping claw turned up firmly is clamped between center connecting rod 6 and external rings body 7, effectively prevents skidding, brings great convenience to operator.
Ring-shaped handle 1 substantially increases the comfort level that operating personnel hold spanner, alleviates the labour intensity of controlled valve.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
Claims (2)
