Abstract
The utility model discloses a kind of multi-functional quick-acting pipe tongs, including pressure handle, front end smallmouth, smallmouth bearing pin, rear end dental lamina and dental lamina bearing pin, the front end smallmouth rearward end is connected to pressure handle upper front end by smallmouth bearing pin, the rear end dental lamina is connected to pressure handle front lower portion by dental lamina bearing pin, the front end smallmouth has an opening, and the angle of the opening is 120 degree.The utility model adds stress point due to increasing by 120 degree of angles at front opening, it is promptly even closer, due to being that bearing pin connection can more increase the dynamics of grasping pipe when pushing shank, due to adding stress point, substantially increase attachment surface so that be rotated part difficult deformation.
Description
Technical field
The utility model is related to mechanical maintenance tool in use technical field, and in particular to a kind of multi-functional quick-acting pipe tongs, it is adaptable to
The industries such as oil, chemical industry, metallurgy, generating, oil refining, shipbuilding, petrochemical industry, machinery.It is equipment installation, device and overhaul of the equipments, maintenance
Required instrument in work；It is particularly suitable for use in irregular bolt, hexagonal nuts and damages bolt, pipe, without hexagonal nuts bolt, broken end spiral shell
Bolt etc..
Background technology
Existing pipe wrench is typically to install manual regulating device or nut on pipe wrench to adjust its folding, by filling manually
Put or nut come tighten or loosen the size of pipe wrench mouthful use it is very inconvenient.Conventional tube tonger as shown in Figure 1 has following
Defect：
(1) traditional only two stress points of pipe wrench are rotated pipe fitting and easily skidded, and strength is big also to become easily pipe
Shape.
(2) to stir handwheel when changing openings of sizes could carry out the change of size, sometimes there is also nut
Situation about killing.
(3) because traditional pipe wrench is in order to keep the rigidity of instrument using entire body iron and steel material quality, compared using carrying
Heavier, bigger specification can more show.
(4) due to being that iron and steel material quality is not belonging to explosion-proof material so can not be used in combustible and explosive area.
In consideration of it, the application is proposed, for solving above-mentioned technical deficiency.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in construction, easy to use, wide using scope
Multi-functional quick-acting pipe tongs.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of multi-functional quick-acting pipe tongs, including pressure handle, front end smallmouth, smallmouth bearing pin, rear end dental lamina and dental lamina bearing pin, it is described
Front end smallmouth rearward end is connected to pressure handle upper front end by smallmouth bearing pin, and the rear end dental lamina is connected to pressure by dental lamina bearing pin
Handle front lower portion, the front end smallmouth has an opening, and the angle of the opening is 120 degree,
Further, contacted at the opening provided with two sawtooth contact surfaces for same pipe fitting.
Further, the front end face of the rear end dental lamina is zigzag.
Further, the rear end of the front end smallmouth sets top power pawl, provided with ejection bullet between the top power pawl and pressure handle
Spring.
Further, spring groove is set on the pressure handle, and the ejector spring is arranged in spring groove.
Further, the front end smallmouth, rear end dental lamina, smallmouth bearing pin and dental lamina bearing pin use steel or copper alloy material
Matter, pressure handle uses aluminum alloy material, can more be shown using lighter bigger specification is carried.
The beneficial effects of the utility model are：
(1) add stress point due to increasing by 120 degree of angles at front opening, it is promptly even closer, when pushing shank by
Then bearing pin connection can more increase the dynamics of grasping pipe, due to adding stress point, substantially increase attachment surface so that be rotated
Part difficult deformation.
(2) as long as lifting and pressing handle when changing openings of sizes, using more fast and reliable, due to without
Nut regulation opening the situation that nut is killed would not occurring using central.
(3) due to front end smallmouth, rear end dental lamina, the bearing pin of connection is all that can be replaced with copper alloy explosion-proof material, institute
That can be used when needing and combustible and explosive area.

Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Fig. 2 a kind of multi-functional quick-acting pipe tongs, including pressure handle 1, front end smallmouth 2, smallmouth bearing pin 3, rear end dental lamina 4
And dental lamina bearing pin 5, the rearward end of front end smallmouth 2 is connected to the upper front end of pressure handle 1 by smallmouth bearing pin 3, and rear end dental lamina 4 passes through dental lamina
Bearing pin 5 is connected to the front lower portion of pressure handle 1, and front end smallmouth 2 has an opening, and the angle of the opening is 120 degree.
Wherein, it is preferred that provided with two sawtooth contact surfaces at opening, contacted for same pipe fitting, the front end face of rear end dental lamina 4
(working face) is zigzag, and the rear end of front end smallmouth 2 sets top power pawl 7, ejector spring 9 is provided between top power pawl 7 and pressure handle 1.
Spring groove 6 is set on pressure handle 1, and ejector spring 9 is arranged in spring groove 6.Front end smallmouth 2, rear end dental lamina 4, smallmouth bearing pin 3 and tooth
Plate bearing pin 5 uses steel or Copper alloy material, and pressure handle 1 uses aluminum alloy material, using carry it is lighter (aluminium alloy it is close
Degree is that three/mono-) bigger specification of steel can more show.As long as lifting and pressing pressure handle 1 i.e. when changing openings of sizes
Can, using more fast and reliable, due to that the situation that nut is killed would not occurring using central without nut regulation opening.
Multi-functional quick-acting pipe tongs when unclamping in use, lift front end smallmouth 2, front end smallmouth 2 revolves around smallmouth bearing pin 3
Turn, so as to drive top power pawl 7 to push so that ejector spring 9 is shunk, and unclamps round steel 8.
When promptly, front end smallmouth 2 is unclamped, ejector spring 9 is ejected, in the presence of ejector spring 9, front end smallmouth
2 rotate around smallmouth bearing pin 3, drive top power pawl 7 to lift, promptly round steel 8.
It should be understood by those skilled in the art that, the utility model is not restricted to the described embodiments, above-described embodiment and
Simply illustrate principle of the present utility model described in specification, on the premise of the utility model spirit and scope are not departed from,
The utility model also has various changes and modifications, and these changes and improvements both fall within claimed the utility model scope
It is interior.Scope is claimed by appending claims and its equivalent thereof in the utility model.
