Abstract

The utility model relates to the technical field of a valve opening device, and particularly relates to a labor-saving valve handle. The labor-saving valve handle provided by the utility model comprises a handle body; the handle body consists of a valve rod sleeve and a grab handle; a sleeve rod hole is formed in the center of the valve rod sleeve; the grab handle consists of multiple sections of square pipes; the multiple sections of square pipes are sequentially shorter and thinner; and the later section of square pipe can be entirely placed in the adjacent previous section of square pipe. According to the labor-saving valve handle, the valve is opened or closed by the multiple sections of telescopic square pipes, the labor intensity of the operator is greatly alleviated, and further the popularization of the valve in industrial application is facilitated. The labor-saving valve handle provided by the utility model has the advantages of simple structure, reasonable setting, low manufacturing cost and the like.

Description

A kind of Labor-saving valve handle

Technical field

The utility model relates to out the control valve unit technical field, particularly a kind of Labor-saving valve handle.

Background technique

Along with the industrial technology development, various valve bodies are widely used in the line equipment control field, and are common by people, and valve body is effectively controlled various pipelines or equipment by switch.Present valve handle is generally disc or straight rod-shaped, and the handle of disc and straight rod-shaped is easy to control some than the switch motion of minor valve; But in the commercial Application of reality, the application of large valve is often used many widely than minor valve, so the operator needs larger power could open or throttle down usually.And discoidal handle skids easily, and the straight rod-shaped handle is shorter because of what take up space and often make; So just cause handle less to the moment of valve hinges, the operator costs larger strength and could open or throttle down.When getting rusty such as valve, the user will more be difficult to open or close, and bring many inconvenience to the operator.Gu the problem such as how can make things convenient for, the labour-saving opens or closes valve to have become the in the industry focus of research.

The model utility content

The purpose of this utility model is for the defective of prior art and deficiency, and Labor-saving valve handle a kind of simple in structure, reasonable in design, easy to use is provided.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of Labor-saving valve handle described in the utility model, comprise handle body, described handle body is comprised of valve lever cover and lever two-part, the central position of described valve lever cover is provided with the loop bar hole, described lever is comprised of some joint square pipes, described some joint square pipes one save than a joint weak point carefully successively, and the square pipe of a rear joint can whole be placed in the square pipe of adjacent last joint successively.

Further, the joint number of described square pipe is three joints.

Further, the back is provided with the reinforcement gusset at the bottom of the pipe of described square pipe.

Further, the back is the ripple glaze shape at the bottom of the muscle of described gusset.

After adopting said structure, the utility model beneficial effect is: a kind of Labor-saving valve handle described in the utility model, comprise handle body, described handle body is comprised of valve lever cover and lever two-part, the central position of described valve lever cover is provided with the loop bar hole, described lever is comprised of some joint square pipes, a described some joint square pipes successively joint are shorter than a joint, the square pipe of a joint can whole be placed in the pipe of square pipe of adjacent last joint successively, when using the utility model, open or throttle down by the multi-joint telescoping square pipe, greatly reduce operator's labor intensity, also be conducive to valve and in commercial Application, further promote.The utlity model has simple in structurely, arrange rationally, the advantage such as fabricating cost is low.

Description of drawings

Fig. 1 is perspective view of the present utility model;

Description of reference numerals:

1, handle body; 11, valve lever cover; 11a, loop bar hole; 12, lever; 12a, pipe back, the end;

2, gusset; 21, back at the bottom of the muscle.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, a kind of Labor-saving valve handle described in the utility model, comprise handle body 1, described handle body 1 is comprised of valve lever cover 11 and lever 12 two-part, the central position of described valve lever cover 11 is provided with loop bar hole 11a, described lever 12 is comprised of some joint square pipes, a described some joint square pipes successively joint are short thinner than a joint, the square pipe of a joint can whole be placed in the square pipe of adjacent last joint successively, Placement between some joint square pipes are adjacent adopts common flexible connection, and square pipe joint number of the present utility model is preferably three joints.From the angle analysis of mechanics, the joint number of square pipe is more, and handle is just larger to the moment of valve hinges, and the operator is just easier to open or throttle down with handle; And valve is larger, and the operator is just more difficult to open or throttle down with handle; So the joint number of square pipe will be decided according to concrete valve size.

In order to increase the rigidity of lever 12, back 12a is provided with and strengthens gusset 2 at the bottom of the pipe of described square pipe; In addition, lever 12 is made by the more piece square pipe, when so the operator also is difficult to unlatching or throttle down in the used square pipe situation that trails, the operator can also insert other pipe bar and prolong handle in square pipe, increase handle to the moment of valve hinges, so that the operator can more easily open or throttle down.

From the angle of ergonomics, back 21 arranges and is the ripple glaze shape at the bottom of the muscle of gusset 2, and the operator just can hold on lever 12 in use like this, can easierly firmly open or throttle down.

Open or during throttle down, can make lever have larger acting force arm with the utility model, can make things convenient for, the labour-saving opens or throttle down, greatly reduces operator's labor intensity, also is conducive to valve further popularization in commercial Application.In addition, this is simple in structure, reasonable in design, low cost of manufacture.

The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
