Abstract
The utility model discloses a multi-angle valve opening-closing wrench, which comprises a body. A plurality of openings are arranged on the body; at least one opening is positioned at the middle part of the body, and at least another opening is positioned at one end of the body; and the shape of each opening accords with that of the cross section of a corresponding valve pin handle. The openings corresponding to the valve pin handle are arranged at the end part and the middle part of the body, so the rib abrasion problem between contact surfaces of the valve pin handle can be better solved, and a plurality of valves can be opened and closed; and at the same time, one opening is also arranged at the middle part of the body, certain valves with narrow operating space can also be opened and closed in a multi-angle manner.
Description
Technical field
The utility model relates to the specific purpose tool technical field, relates in particular to a kind of switch knob that is used for valve.
Technical background
In modern industrial equipment and production equipment, the application of all kinds of air valves, water valve is very general.Regular job is very high to the frequency thing that these valves carry out repeatedly switch.
Because the restriction of structure is opened these valves generally speaking and all is to use monkey wrench.The monkey wrench that tradition is used comes adjustable clamp mouth size by the hand-screw worm screw, makes the face that clamps together of folder mouth form tight the contact with the pin handle contact-making surface of valve, thereby opens or valve-off by the rotation of monkey wrench.The long-term monkey wrench that adopts is opened or valve-off, can cause rib between the pin handle contact-making surface formation circular arc that is worn, thus operation movable wrench is opened valve or during shutoff operation, is puted forth effort on circular arc once more, skids easily, wayward.When even more serious, do not note slightly during operation, also cause wrist to sprain easily, operating personnel are caused personal injury.
In addition, the folder mouth that contacts with the valve pin handle on the existing monkey wrench all is located at the top of spanner.So the advantage of design be moment of torsion greatly, more laborsaving, but that shortcoming is the operating space that takies is big.When adopting existing monkey wrench unlatching or shutoff operation, just need each side of valve that the operating space that can hold whole spanner length can both be provided.Therefore, the application of existing spanner has many restrictions.
The utility model content
In view of the above problems, the purpose of this utility model be to propose a kind of operating space little, to the little valve switch spanner of the wearing and tearing of the rib between the valve pin handle contact-making surface.
For achieving the above object, multi-angle valve switch spanner of the present utility model comprises a body, and described body is provided with a plurality of perforates, and at least one described perforate is positioned at described body middle part, and another described perforate is positioned at described body one end at least; The shape of each described perforate is consistent with corresponding valve pin handle shape of cross section.
Preferably, an end of described body is provided with the cross perforate, and the other end is provided with two rectangle openings, and the middle part of described spanner is provided with a rectangle opening.
The utility model is provided with and the corresponding perforate of valve pin handle by two ends and middle part at body owing to adopted the said structure design, has solved the wear problem of rib between the valve pin handle contact-making surface preferably.While also can the multi-angle controlled opening/closing to the valve that some operating space is narrow and small owing to also being provided with perforate at the middle part.
Be described further below with reference to the technique effect of accompanying drawing, to understand the purpose of this utility model, feature and effect fully design of the present utility model, concrete structure and generation.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model one specific embodiment.
The specific embodiment
The description of utility model purport can more clearly understand others of the present utility model and advantage with reference to following the explanation in conjunction with the accompanying drawings by example.
As shown in Figure 1, multi-angle switch knob of the present utility model comprises body 10.Body 10 is made by metal rectangular plate, and it has certain thickness so that enough intensity to be provided.
One end place of body 10 has the rectangle opening 1 and rectangle opening 2 that is used for rectangle valve pin handle.Perforate 1 varies in size with perforate 2, to be used for the rectangle valve pin handle of different sizes.
Body 10 other end places have the cross perforate 4 that is used for cross valve pin handle.
The middle part of body 10 has the rectangle opening 3 that is used for rectangle valve pin handle, and the size of perforate 3 is greater than perforate 1 and perforate 2.
Of particular note, in above-mentioned each perforate, preferentially will be arranged on the middle part of body corresponding to the perforate of the little valve in operating space.
In other embodiment of the present utility model, the shape of above-mentioned perforate can be different according to the shape of cross section of valve pin handle.
Operation of the present utility model is described below.
During use, according to different valve pin handle (not shown in figure 1)s, corresponding perforate cover is on it with it, and rotating body 10 is to open or valve-off then.
Because the two ends, the left and right sides of body 10 are provided with perforate 1,2 and 4, therefore, when these perforates of use, spanner 10 to turn round arm longer, use more laborsaving.Particularly, because the shape of each perforate is consistent with the shape of cross section of valve pin handle, so the whole inner edge of perforate all contacts with corresponding valve pin handle side, and is just little to the wearing and tearing of the rib on the valve pin handle contact-making surface.
In addition, the middle part of body 10 also is provided with perforate 3, and when using perforate 3, than existing monkey wrench, the space on the spanner 10 occupied valve both sides of present embodiment is less, and can exert oneself from different perspectives.
Therefore, under or the situation that work angle limits to some extent less at the valve surrounding space, spanner of the present utility model also can be used.In addition, be enclosed within on the valve pin handle application of force rotation because body 10 in use, is whole perforate, rib between the pin handle contact-making surface therefore can not wear and tear.Moreover therefore spanner of the present utility model, is difficult for slippage in the time of firmly because of being that whole perforate is enclosed within application of force rotation on the valve pin handle, has guaranteed the safety of operator's hand.
In sum, be several preferred embodiment of the present utility model described in this specification.All technical staff in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in claim protection domain of the present utility model.
Claims (2)
1, a kind of multi-angle valve switch spanner comprises a body, and described body is provided with a plurality of perforates, and at least one described perforate is positioned at described body middle part, and another described perforate is positioned at described body one end at least; The shape of each described perforate is consistent with corresponding valve pin handle shape of cross section.
2, multi-angle valve switch spanner as claimed in claim 1 is characterized in that, an end of described body is provided with the cross perforate, and the other end is provided with two rectangle openings, and the middle part of described body is provided with a rectangle opening.
