Abstract
The utility model relates to a pair of boosting pipe pliers, which is composed of a movable pliers opening, an adjusting nut, a pliers body and a pliers handle. The pliers handle which adopts sleeve pipe type structure is composed of a sleeve pipe and a boosting draw rod which can be extended and shrunk in the sleeve pipe. In the utility model, a positioning device of the boosting draw rod can be arranged on the sleeve pipe to fix the length of the whole pliers handle, which is convenient for applying force. The utility model has the advantages of reasonable structure, simple adjustment and convenient and reliable operation and use. The utility model which is suitable for the working requirements of various pipe diameters and various kinds of twisting trisquare.
Description
The utility model relates to a kind of hand tools, specifically a kind of Boost pipe tongs.
We know that pipe wrench is the indispensable instrument of various pipeline dismounting operations.At present, what generally use is GB8406-87 type pipe wrench, it is made up of moving jaw, adjusting nut, pincers handle body, moving jaw is contained in the trepanning of pincers handle body by adjusting nut, rotate adjusting nut, moving jaw can move forward and backward along pincers handle body, regulates jaw size with this, and above-mentioned pipe wrench reliably is used widely because of simple in structure, use.But because the decreased food of pincers handle body is certain, use is restricted, and is difficult to satisfy the different needs of twisting the square operation of same pipeline.In addition, above-mentioned pipe wrench does not have the performance of regulating clamping force, and clamping force is crossed the phenomenon that bad pipe fitting appears crushing or pressing from both sides in conference sometimes.
The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, and decreased food is adjustable, and is easy to use, reliable, can satisfy the Boost pipe tongs of various stubborn square operation needs.
For achieving the above object, a kind of Boost pipe tongs, it is made up of moving jaw, adjusting nut, caliper, pincers handle, it is characterized in that; The pincers handle adopts sleeve type structure, is made up of sleeve pipe and afterburning pull bar, and afterburning pull bar can stretch in sleeve pipe.Also can be provided with afterburning pull bar positioner on the utility model sleeve pipe, with fixing whole pincers handle length, firmly convenient.
The utility model adopts the telescopic pincers handle of sleeve pipe, can satisfy the needs of various stubborn square operations during use, has avoided frequently changing the deficiency of pincers, and is easy to use, reliable.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model structural representation.
As can be seen from Figure 1, a kind of Boost pipe tongs, it is provided with moving jaw 1, caliper 2, adjusting nut 4, and by rotating adjusting nut 4, moving jaw 1 can move forward and backward along caliper, regulates jaw size, also adorns intrinsic fixed teeth 3 on the caliper.Above-mentioned composition structure is same as the prior art, belongs to prior art, and this does not describe in detail.
The utility model caliper rear end is connected with a telescopic pincers handle.This pincers handle adopts sleeve type structure, is made up of sleeve pipe 7 and afterburning pull bar 9, and the sleeve pipe front end adopts with caliper and is threaded, and for guaranteeing its intensity, the junction also is provided with one and reinforces cover 6.Afterburning pull bar 9 can stretch in sleeve pipe 7, to regulate the length of whole pincers handle, satisfies the needs of various stubborn square operations.When strengthening moment, elongate afterburning pull bar and get final product as need.Also can be provided with afterburning pull bar positioner on the utility model sleeve pipe, for example: it can adopt jackscrew alignment pin location, also can adopt self-tightening to locate stifled loop mapping at the sleeve pipe tail end, is provided with jump ring 10 in the stifled ring in location, radially tightens the afterburning pull bar of pulling out at any time.Can determine the length of whole telescopic pincers handle so easily, it is afterburning to be convenient to operation.
The utility model is for controlling the size of clamping force effectively, and caliper 2 rear ends also are provided with jaw and clamp adjustable ring 5, and it is an eccentric adjusting ring.Can regulate the angle of the relative caliper fixed teeth of moving jaw,, control the size of clamping force effectively, avoid the excessive pipe fitting that crushes of clamping force according to different pipe fitting requirements.As shown in fig. 1, by regulating eccentric adjusting ring 5, the relative caliper fixed teeth of moving jaw is parallel, and can not produce clamping force when using this moment, can use as a spanner.
The utility model is rational in infrastructure, regulates simply, and is easy for operation, reliable, is suitable for various calibers and the different square operation needs of twisting, and is a kind of desirable Boost pipe tongs.
Claims (3)
1, a kind of Boost pipe tongs, it is made up of moving jaw, adjusting nut, caliper, pincers handle, it is characterized in that; The pincers handle adopts sleeve type structure, is made up of sleeve pipe and afterburning pull bar, and afterburning pull bar can stretch in sleeve pipe.
2, Boost pipe tongs as claimed in claim 1 is characterized in that also being provided with on the said sleeve pipe afterburning pull bar positioner, and it is at the stifled ring in the sheathed location of sleeve pipe tail end, is provided with a jump ring in the stifled ring in location, and jump ring radially clamps afterburning pull bar.
3, Boost pipe tongs as claimed in claim 1 is characterized in that the also sheathed eccentric adjusting ring in said caliper rear end.
