Description
Technical field
The utility model relates to Manual pipe tongs field, in particular to a kind of pipe wrench.
Background technology
Pipe wrench in the market is mostly made up of regular jaw, moving jaw, pipe wrench handle, adjusting nut etc., regular jaw and pipe wrench handle are fixed together, the front end of pipe wrench handle is regular jaw, the V-shaped flank of tooth in inner side of regular jaw, the V-shaped flank of tooth in front end of moving jaw.Drive moving jaw to move change jaw opening amount size by adjusting nut and carry out work, it is widely used in clamping and the circular tubing workpiece of turn-knob.Rotating adjusting nut during use, nut, threaded engagement rotate the movement of adjustment moving jaw, the opening amount size of the relative regular jaw of moving jaw is changed, clamps circular tubing workpiece.
In use need bimanualness, constantly rotating adjusting nut, repeatedly adjust jaw opening amount, therefore, governing speed is slow, wastes time and energy.The pipe wrench of other quick adjustment opening, can not finely tune, many times not clamping, and skidding appears in jaw clamping, easy damaged surface of the work.
Utility model content
The purpose of this utility model is to provide a kind of pipe wrench, to solve the deficiencies in the prior art.
For realizing the utility model object, the technical scheme of employing is:
A kind of pipe wrench, the moving jaw comprising pipe wrench handle, be fixedly connected on the regular jaw on pipe wrench handle and be flexibly connected with pipe wrench handle, it is characterized in that, the axis of described pipe wrench handle offers through hole, and the through-hole wall of its tail end is provided with a tapered enlarging expanded outwardly, pipe wrench handle tail end is provided with locking cap, and the outer surface of pipe wrench handle tail end is connected by threaded engagement with locking cap inner surface; Described pipe wrench handle is provided with the push rod running through through hole, and push rod one end is stretched out locking cap and is connected with locating piece, and the other end is fixedly connected with moving jaw; The periphery of described push rod and moving jaw link is provided with helical tooth, and the periphery of the other end is provided with rule; Be provided with one between the tapered enlarging of described pipe wrench handle and locking cap and be enclosed within snap ring on push rod; The gear matched with helical tooth is provided with in the middle part of described pipe wrench handle.
Further, described snap ring is annular snap ring, and annular snap ring is provided with opening.By annular snap ring gripping push rods, increase snap ring service life, clamp the advantages such as firm.
Further, the periphery of described push rod and the inner headed face matched in clearance of pipe wrench handle.Be conducive to making moving jaw displacement and regular jaw clamp body, and avoid moving jaw to offset when clamping body, easy damaged surface of the work.
The beneficial effects of the utility model are, by promoting push rod, moving jaw is moved fast to body, after moving jaw touches body, swing pinion again, is coordinated with the helical tooth of push rod by gear, thus regulates moving jaw and regular jaw to clamp body, finally tighten locking cap, make snap ring gripping push rods, avoid push rod to be moved, realize body clamping.This pipe wrench moved promotion push rod fast near body, increased work efficiency.Being regulated by gear trace makes moving jaw and regular jaw reliably clamp body, avoids moving jaw to clamp and occurs skidding, damage tube surfaces.Be provided with rule by push rod, be convenient for measuring some simple sizes, improve work task efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the pipe wrench that the utility model provides.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 is shown pipe wrench that the utility model provides, comprises pipe wrench handle 1, regular jaw 2, moving jaw 3, push rod 4, gear 5, rule 6, snap ring 7, locking cap 8, locating piece 9 and body 10.Described pipe wrench handle 1 is fixedly connected with regular jaw 2, and pipe wrench handle 1 is flexibly connected with moving jaw 3; The axis of described pipe wrench handle 1 offers through hole, and the through-hole wall of its tail end is provided with a tapered enlarging expanded outwardly, and pipe wrench handle 1 tail end is provided with locking cap 8, and the outer surface of pipe wrench handle 1 tail end is connected by threaded engagement with locking cap 8 inner surface; Described pipe wrench handle 1 is provided with the push rod 4 running through through hole, and push rod 4 one end is stretched out locking cap 8 and is connected with locating piece 9, and the other end is fixedly connected with moving jaw 3; Described push rod 4 is provided with helical tooth with the periphery of moving jaw 3 link, and the periphery of the other end is provided with rule 6; Be provided with one between the tapered enlarging of described pipe wrench handle 1 and locking cap 8 and be enclosed within snap ring 7 on push rod 4; The gear 5 matched with helical tooth is provided with in the middle part of described pipe wrench handle 1.
Snap ring 7 is annular snap ring, and annular snap ring is provided with opening.By annular snap ring gripping push rods 4, increase snap ring 7 service life, clamp the advantages such as firm.The periphery of push rod 4 and the inner headed face matched in clearance of pipe wrench handle 1.Be conducive to making moving jaw 3 displacement and regular jaw 2 clamp body 10, and avoid moving jaw 3 to offset when clamping body 10, easy damaged body 10 surface.
By promoting push rod 4, moving jaw 3 is moved fast to body 10, after moving jaw 3 touches body 10, swing pinion 5 again, coordinated by the helical tooth of gear 5 with push rod 4, thus regulate moving jaw 3 and regular jaw 2 to clamp body 10, finally tighten locking cap 8, make snap ring 7 gripping push rods 4, avoid push rod 4 to be moved, realize body 10 and clamp.This pipe wrench moved promotion push rod 4 fast near body 10, increased work efficiency.Being regulated by gear 5 trace makes moving jaw 3 and regular jaw 2 reliably clamp body 10, avoids moving jaw 3 to clamp and occurs skidding, damage body 10 surface.Push rod 4 is provided with rule 6, clamps the part needing to measure, be convenient for measuring some simple sizes by locating piece 9 and locking cap 8, improves work task efficiency.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
