Description
Technical field
The present invention relates to a kind of water, electricity and gas installation pipe wrench, more particularly to a kind of water, electricity and gas installation pipe wrench based on lever principle.
Background technology
Used traditional water, electricity and gas installation pipe wrench more, can so improve frictional force, so as to improve the stability of clamping body.But; many water, electricity and gas tube surfaces have the strong epoxy resin protective layer of one layer of anti-corrosion capability; for protecting body; extend its life-span; if clamped to body through frequently with the pipe wrench with latch jaw; the protective layer of tube surfaces can be then destroyed, body is got rusty, leakage can be even caused when serious.If remove the latch of the jaw of traditional pipe wrench, then traditional pipe wrench can be made to there is a problem of that frictional force deficiency, clamping are not sufficiently stable.
In order to solve the above problems, Patent No. " ZL
201520246159.1 " patent of invention discloses a kind of lossless pipe wrench; the movable clip including fixed handle, movable handle and arch; the front end of fixed handle is provided with fixing clamp vertical with fixed handle shank and for arch; the front end of movable handle is provided with hook; the front end of movable handle is hinged with the front end of fixed handle at fixing clamp rear portion; be hinged at one end of movable clip and the lower end fixed handle of fixing clamp, the other end is hinged with a fixture block, fixture block is provided with the pin of horizontal direction.The pipe wrench significantly increases chucking power using lever principle, so its jaw does not have latch can stably clamp body yet；But, the movable handle of the pipe wrench is coordinated by lever and fixture block in use, and it is disconnected structure, and there is a problem of skidding in use causes stability not enough.
The content of the invention
The purpose of the present invention is that and provides a kind of using anodontia jaw and the strong water, electricity and gas installation pipe wrench based on lever principle of stability in order to solve the above problems.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of water, electricity and gas installation pipe wrench,Including first handle and second handle,Vice jaw part with the pipe wrench is as front end,The front end of the first handle is provided with jaw seat,The front end of the jaw seat is provided with the first indent arc vice jaw,The front end of the jaw seat is rotatably connected with one end of bow by bearing pin,The other end of the bow is rotatably connected with the first end of straight-bar by bearing pin,The second indent arc vice jaw is provided with rear side of the bow,The front end of the second handle is " L " shape bar,The turning position of " L " the shape bar is rotatably connected with the rear portion of the jaw seat by bearing pin,The outer-end rear side surface of " L " the shape bar is provided with first limited block and the second limited block of evagination,The straight-bar is provided with bar hole and its first end opening,Remain silent at the second end,The outer end of " L " the shape bar is placed in the bar hole of the straight-bar and the second end termination of the straight-bar is located between first limited block and second limited block.
Preferably, first limited block is located at the outer-most end surface uniform circular arcs shape of the outermost end of described " L " shape bar, the front side surface of first limited block and " L " the shape bar.
Further, it is more laborsaving when in use for the ease of pipe wrench, it is provided with extension spring between the first handle and the second handle.
Preferably, the extension spring is between the middle part and the middle part of the second handle of the first handle.
The beneficial effects of the present invention are：
The present invention significantly increases chucking power using lever principle, so its jaw does not have latch can stably clamp body yet；By the structure cooperated using bow, straight-bar and " L " shape bar, it is ensured that pipe wrench stable drive in use, stability in use is improved, overcome the problem skidded and cause stability not enough；Use to mount between straight-bar and " L " shape bar and be connected and spacing with two limited blocks, while stability is ensured, be also convenient for separating straight-bar and " L " shape bar so that between the first indent arc vice jaw and the second indent arc vice jaw can significantly enlarging, be easily installed the bigger body of diameter.

Fig. 2 is the two of the main structure diagram of water, electricity and gas installation pipe wrench of the present invention；
Fig. 3 is the top view of straight-bar of the present invention, its visual angle with the visual angle in Fig. 1 and Fig. 2 be main view visual angle.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings：
As shown in figures 1 and 3,Water, electricity and gas installation of the present invention includes first handle 11 and second handle 9 with pipe wrench,Vice jaw part with the pipe wrench is as front end,The front end of first handle 11 is provided with jaw seat 8,The front end of jaw seat 8 is provided with the first indent arc vice jaw 6,The front end of jaw seat 8 is rotatably connected with one end of bow 1 by bearing pin,The other end of bow 1 is rotatably connected with the first end of straight-bar 3 by bearing pin,The rear side of bow 1 is provided with the second indent arc vice jaw 2,The front end of second handle 11 is " L " shape bar 7,The turning position of " L " shape bar 7 is rotatably connected with the rear portion of jaw seat 8 by bearing pin,The outer-end rear side surface of " L " shape bar 7 is provided with first limited block 4 and the second limited block 5 of evagination,First limited block 4 is located at the outermost end of " L " shape bar 7,The front side surface of the first limited block 4 and the outer-most end surface uniform circular arcs shape of " L " shape bar 7,Straight-bar 3 is provided with bar hole 12 and its first end opening,Remain silent at the second end,The outer end of " L " shape bar 7 is placed in the bar hole 12 of straight-bar 3 and the second end termination of straight-bar 3 is located between the first limited block 4 and the second limited block 5,Extension spring 10 is provided between the middle part of first handle 11 and the middle part of second handle 9.
With reference to Fig. 1, when using, hand-held first handle 11 and second handle 9 simultaneously make second handle 9 outwards rotate to an angle, and " L " shape bar 7 drives straight-bar 3 and bow 1 to rotate, increase the spacing between the first indent arc vice jaw 6 and the second indent arc vice jaw 2, be easy to be put into body；After being put into body, second handle 9 is pushed, now extension spring 10 also can because of reseting elasticity provided auxiliary power, " L " shape bar 7 drives straight-bar 3 and bow 1 to reversely rotate, reduce the spacing between the first indent arc vice jaw 6 and the second indent arc vice jaw 2, be easy to tightly clamp body.
As shown in Figures 2 and 3, it is necessary to by the enlarging amplitude between the first indent arc vice jaw 6 and the second indent arc vice jaw 2 further increase in order to install during the bigger body of diameter, after second handle 9 is outwards rotated to an angle, hand-held straight-bar 3 is pulled back（Or promote）A bit, then straight-bar 3 is lifted up making its bar hole 12 pass through the first limited block 4, until making straight-bar 3 completely disengage from " L " shape bar 7, at this moment can be with rotating curved bar 1 to maximum angle, in order to install the bigger body of diameter between the first indent arc vice jaw 6 and the second indent arc vice jaw 2.
Above-described embodiment is presently preferred embodiments of the present invention; it is not the limitation to technical solution of the present invention; as long as without the technical scheme that creative work can be realized on the basis of above-described embodiment, it is regarded as falling into the rights protection scope of patent of the present invention.
