Abstract
The utility model relates to a strong pipe tong, which is provided with a fixed tong body, a movable tong body, and a tong handle, wherein, the fixed tong body is hinged with the tong handle, and the fixed tong body and the movable tong body are in arc shapes and are hinged into an O-shaped tong body. The inner side of the tong body is movably provided with tenon groove type clamping tooth blocks. The utility model adopts an O-shaped tong body structure. The utility model has the advantages of reasonable structure, small volume, high clamping performance, large twist resisting strength, and safety. The utility model is widely suitable for the operation of the installation of pipelines with high strength and high clamping performance.
Description
The utility model relates to a kind of hand tools, specifically a kind of Strong pipe wrench.
We know, oil, chemical industry use the toggle machine to tighten and when unscrewing pipeline, an oil pipe wherein be fixed, and pipe wrench is the instrument of an indispensability.At present, what generally use is GB8406-87 type pipe wrench, and it is made up of moving jaw, adjusting nut, pincers handle body, and moving jaw is contained in the trepanning of pincers handle body by adjusting nut, rotates adjusting nut, can adjust jaw size.This pipe wrench uses reliably and is used widely because of simple in structure.But it is limited that its maximum is born moment of torsion, during use, fracture, bending and nut, screw thread distortion often occur, the phenomenon that can not regulate again.
The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple and reasonable for structure, easy to adjust, clamps firmly torsional strength height, the Strong pipe wrench that clamping force can be effectively controlled.
For achieving the above object, a kind of Strong pipe wrench, it is provided with fixed caliper, moving caliper, pincers handle, fixed caliper is hinged with the pincers handle, it is characterized in that fixed caliper, moving caliper are camber, the two is hinged into one " O " type caliper, and the inboard activity of caliper is equipped with tongue and groove and is clamped block teeth.
Form " O " type caliper when the utility model clamps, pipe fitting is embraced in the centre, by rotating crowbar formula pincers handle, moving caliper inwardly shrinks, and pipe fitting is securely fixed in the caliper, has avoided original pipe wrench to skid and dangerous phenomenons such as jaw comes off, fracture.The utility model is rational in infrastructure, and is easy to adjust, the torsional strength height, and it is good, safe and reliable to clamp performance.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
As can be seen from Figure 1, a kind of Strong pipe wrench, it is provided with fixed caliper 1, moving caliper 2, pincers handle 4, and the utility model pincers handle 4 adopts the crowbar formula, and pincers handle 4 front ends are hinged by rotating shaft 5 and fixed caliper 1.Fixed caliper 1 and moving caliper 2 are camber, and the two hinge is combined into one " O " type caliper, during use pipe fitting is embraced in the centre, and moving caliper 2 inwardly shrinks, and coming off can not appear in jaw, phenomenon of rupture.
The utility model fixed caliper 1 and moving caliper 2 inboards are equipped with and are clamped block teeth 3, they form large tracts of land or integral retaining pipe fitting, clamping force is all fair, pipe fitting can not be out of shape, moving caliper 2 inwardly shrinks, when the front end of moving caliper 2 came to the bottom land of fixed caliper 1, clamping force can stop, and is effectively controlled.Clamp block teeth 3 and adopt tongue and groove to flexibly connect, like this, conveniently adjusted replacing.In order to enlarge the adjusting range of jaw size, can adopt the clamping block teeth of different sizes, conversion clamping diameter is to satisfy different needs.
The utility model adopts " O " caliper structure, and it is rational in infrastructure, and volume is little, and is in light weight, clamps the performance height, and torsional strength is big, and is safe and reliable, is widely applicable for the installation exercise of high strength, high gripping performance pipeline.
