The specific embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model provides a kind of valve well opener, and said valve well opener comprises well lid hook, valve opening key and valve opening handle.
As shown in Figure 1, said well lid hook comprises crossbeam 1 and hook portion 2.Said hook portion 2 is fixedly set in the below of crossbeam 1.Wherein, hook portion 2 can be inserted in the eyelet on the well lid of valve well, and hooks well lid, directly promotes crossbeam 1 then or promote crossbeam 1 through lever principle can well lid be opened.
As shown in Figure 2, said valve opening key comprises key bar 5 and the key core 4 of being located at key bar 5 one ends and being structure as a whole with key bar 5.The other end of said key bar 5 is a square pole section 6.
As shown in Figure 1, said well lid hook comprises crossbeam 1 and the hook portion 2 that is fixedly set in crossbeam 1 below.Be provided with between said crossbeam 1 and the hook portion 2 and be used for first through hole 10 that key bar 5 passes.Particularly, as shown in Figure 1, be fixedly connected said first through hole 10 of formation between said two braces and the crossbeam 1 through two braces (i.e. first brace 3) between the hook portion 2 of said well lid hook and the crossbeam 1.
As shown in Figure 3, said valve opening handle comprises handle cross bar 7 and the cylindricality connector 8 that is fixedly connected with handle cross bar 7, and said cylindricality connector 8 and the 7 vertical settings of handle cross bar.Be fixedly connected through two braces (i.e. second brace 9) between the handle cross bar 7 of said valve opening handle and the cylindricality connector 8.
Shown in Fig. 3 and 4, the bottom of said cylindricality connector 8 is provided with and square pole section 6 form fit of key bar 5 and the square blind hole 81 that supplies the square pole section 6 of key bar 5 to insert, and the side of cylindricality connector 8 is provided with and is used for second through hole 82 that key bar 5 passes.The shape of the square blind hole 81 on the cylindricality connector 8 must with the form fit of the square pole section 6 of key bar 5, otherwise key bar 5 rotates in square blind hole 81, then can't key core 4, also can't open valve.
Said key core 4 is the Key structure of various Open valves commonly used in the prior art, for example can comprise inner core and shell (not shown in the accompanying drawing), but be not limited to this.
In the utility model, said key bar 5 can be different shape, for example can be cylindrically, but is not limited to this.Second through hole 82 on the side of said cylindricality connector 8 is used for passing of key bar 5, and the shape of second through hole 82 need not to mate fully with the shape of key bar 5, as long as key bar 5 can pass this second through hole 82.Under the preferable case, when key bar 5 was cylindrical, second through hole 82 was circular.
The valve well opener that the utility model provides can make up use in use as follows:
(1) with valve opening key and the combination of valve opening handle, can obtain the valve opening combination tool.Particularly, as shown in Figure 5, the square pole section 6 of key bar 5 is inserted in the square blind hole 81 of cylindricality connector 8, promptly obtain said valve opening combination tool.
At this moment, on the key core 4 insertion valves with key bar 5 other ends, turning handle cross bar 7, through square blind hole 81 drive key bars 5 rotations of cylindricality connector 8, thereby key core 4 is opened valve.
(2) with well lid hook, valve opening key and the combination of valve opening handle, can obtain well lid unlatching combination tool, use under the situation that this instrument is dumb at well lid, be difficult to open; Particularly; As shown in Figure 6; In the crossbeam 1 that earlier key bar 5 is passed the well lid hook and two first brace 3 formed first through holes 10, and then key bar 5 passed in second through hole 82 on the side of cylindricality connector 8, promptly obtain well lid unlatching combination tool.
At this moment; The hook portion 2 that said well lid is opened the well lid hook of combination tool is inserted in the eyelet on the well lid of valve wells; And hook well lid, with the handle cross bar 7 of valve opening handle as supporting bottom bar, with cylindricality connector 8 as fulcrum; With key bar 5 as lever, thereby promote crossbeam 1 and open well lid.Dismantle aforementioned well lid then and open combination tool, and valve opening key and valve opening handle are made up, obtain the valve opening combination tool, and adopt aforementioned same step can open valve by the aforementioned identical step of employing shown in Figure 5.
If well lid is opened easily, can directly adopt well lid opening of hook well lid.
The operating principle of the valve well opener that the utility model provides is:
When the valve well lid is flexible, can directly adopt well lid opening of hook well lid, then valve opening key and valve opening handle combination use are opened valve.Particularly, directly the hook portion 2 of well lid hook is inserted in the eyelet on the well lid of valve wells, and hooked well lid, directly promoting crossbeam 1 then can open well lid.By above-mentioned steps valve opening key and valve opening handle are made up then; Obtain the valve opening combination tool; And on the key core 4 insertion valves with the valve opening combination tool, turning handle cross bar 7 is through square blind hole 81 drive key bars 5 rotations of cylindricality connector 8; Thereby key core 4 is opened valve.
When the valve well lid is opened at need; Earlier well lid hook, valve opening key and valve opening handle combination combination are obtained well lid and open combination tool; Utilize lever principle to open well lid; Then valve opening key and the combination of valve opening handle are obtained the valve opening combination tool, and open valve.Particularly; As shown in Figure 6; In the crossbeam 1 that earlier key bar 5 is passed the well lid hook and two first brace 3 formed first through holes 10, and then key bar 5 passed in second through hole 82 on the side of cylindricality connector 8, promptly obtain well lid unlatching combination tool.The hook portion 2 that said well lid is opened the well lid hook of combination tool is inserted in the eyelet on the well lid of valve wells; And hook well lid; With the handle cross bar 7 of valve opening handle as supporting bottom bar; With cylindricality connector 8 as fulcrum, with key bar 5 as lever, thereby promote crossbeam 1 and open well lid.Dismantle aforementioned well lid then and open combination tool, and valve opening key and valve opening handle are made up, obtain the valve opening combination tool, and adopt aforementioned same step can open valve by the aforementioned identical step of employing shown in Figure 5.
The valve well opener that the utility model provides uses simply, quick, laborsaving, convenient and practical, and light and handy, easy to carry, makes simple, with low cost.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
