Description

A kind of convenient pipe vice

Technical field

The present invention relates to hardware ＆ tools field, it is specifically related to a kind of convenient pipe vice.

Background technology

In daily life with produce, all can using to pipe vice, for tightening or unscrewing pipe so as to carry out changing, Maintenance, dismounting, but current pipe vice is all to rotate by finger friction to adjust the size that worm screw adjusts pipe jaw, makes pipe Pipe tightened by son pincers；The pipe vice of this spline structure, by finger friction rotary worm, tends not to effectively tighten jaw, in work In work, can skid between jaw and pipe, meanwhile, especially in long work process, multipass finger rotary worm To tighten or to unscrew pipe, not only injury can be produced to finger, and inefficiency；In addition, for the pipe of different tube diameters, needing Using various sizes of pipe vice, if less pipe vice, its jaw for big pipe too shallow it is impossible to clamp big Pipe, is applying the standby different pipe vice of man-hour requirement, cumbersome.

Content of the invention

For solving above-mentioned technical problem, the invention provides a kind of convenient pipe vice, its can easy adjustment jaw to step up Pipe, also adapts to the pipe of Multiple Type simultaneously, easy to use.

A kind of convenient pipe vice of the present invention, including activity clamp handle, is vertically installed in described activity clamp handle head end Movable binding clip, the fixed pliers head adjusting clamp handle, being vertically installed in described regulation clamp handle head end, described regulation clamp handle upper surface is horizontal To being provided with chute, the front-rear side walls of described chute are arranged with " u " shape groove, are integrally formed in described u shape groove and are provided with conditioning box, Described regulation inframe is transversely provided with worm screw, and described regulation clamp handle end is provided with turning handle, and described turning handle is by the company being located in chute Extension bar is connected with described worm screw, and described activity clamp handle is horizontally through described conditioning box and is located above described regulation clamp handle, described Teeth with the cooperation of described worm screw are transversely provided with the lower wall of activity clamp handle, described turning handle drives described work by described turbine Caliper handle is along described chute transverse shifting.

Movable binding clip and fixed pliers head respectively with activity clamp handle and adjust clamp handle and be integrally formed and corresponding respectively vertical set In activity clamp handle and regulation clamp handle front end, activity clamp handle is located at and adjusts above clamp handle, structure between movable binding clip and fixed pliers head The jaw becoming, movable binding clip and fixed pliers head medial wall is preferably provided with groove to increase the friction between jaw and pipe； Turbine two ends are located in u shape groove, and hand dynamic turning handle drives turbine rotation by connecting rod, makes ratcheting with it work above turbine Caliper handle moves forwards or backwards, thus changing the size of jaw, hand turning handle can make jaw firmly clamp pipe, without Occurring twisting because of jaw does not tightly lead to the phenomenon skidded to occur；For increasing the frictional force of jaw and pipe further, can live respectively The relative inner wall of dynamic binding clip and fixed pliers head is provided with groove.

Improve further, described chute bottom is transversely provided with slide rail, described activity clamp handle end is provided with slide bar straight down, Described slide bar lower end and described slide rail are slidably connected, and described slide bar is provided with the through hole passing through for described adapting rod.

Described activity clamp handle, with the transmission transverse shifting of worm screw, for the friction between reduction activity clamp handle and turbine, makes pincers Mouth regulation is lighter, arranges slide bar in activity clamp handle end, and its lower end is located in chute along slide rail slip, carries to activity clamp handle While for support force, also make activity clamp handle mobile lighter, extend the service life of turbine.

Improve further, in described chute, the one end near fixed pliers head is transversely provided with spring, the other end of described spring It is connected with described slide bar.

At ordinary times under off working state, jaw is closure, and movable binding clip and fixed pliers head fit together, when needs add During tight pipe, rotate turning handle, be that turbine promotion activity clamp handle moves out, movable binding clip and fixed pliers head separately, slide bar to Spring one end motion compresses spring, jaw clamps pipe, and adjusting worm screw makes jaw step up pipe, and now the bounce of spring also pushes away Moving slide-bar, movable binding clip is in the trend moved to fixed pliers head direction, increased between movable binding clip and fixed pliers head Chucking power, further improve the grip force of jaw, it is to avoid skids between jaw and pipe.

Improve further, described adjustable clamp cephalic par rotates and is provided with movable binding clip, the cross section of described activity binding clip For " n " shape.

The first end of described adjustable clamp is rotated with the end of movable binding clip and is connected, and described activity binding clip cross section is " n " Shape, it can turn folding to movable binding clip direction, and its opening side is fastened on movable binding clip；Tighten size at ordinary times less During pipe, movable binding clip is fastened on movable binding clip medial surface, during process larger sized pipe, by movable binding clip to Outer rotating opening, movable binding clip connects into a larger elbow with movable binding clip, increases the depth of jaw, can block relatively The pipe of Large Diameter Pipeline；For increasing frictional force, it is all provided with teeth in the opening side of movable binding clip and closing side corresponding thereto Stricture of vagina.

Improve further, the end of described fixed pliers head rotates and is provided with fixed pliers head, described fixed pliers head transversal Face is " n " shape.

Fixed pliers head as the principle of above-mentioned activity binding clip, during the pipe of fixture pipe with small pipe diameter, roll over by fixed pliers head On the medial wall of fixed pliers head, first constitutes jaw to stacking with adjustable clamp；When the big pipe of fixture, by fixed pliers head Outwards turnover is opened, and fixed pliers head and fixed pliers head are linked to be a larger elbow, with movable binding clip and movable binding clip One deeper jaw of one composition, is more convenient for blocking Large Diameter Pipeline pipe, easy to operate；For increasing frictional force further, solid Determine the opening side of binding clip and closing side corresponding thereto is equipped with groove.

Of the present invention have the beneficial effect that structure is simple, easy to use, jaw can be made quickly to step up pipe, prevent from beating Sliding it is adaptable to the tube to tubesheet of multiple calibers.
