Abstract

The utility model relates to a novel pipe tongs which relates to a tool specially used for assembling and disassembling threaded connecting pipe fittings. The utility model is composed of an upper tongs lip, a lower tongs lip and a spring, wherein, the lower tongs lip forms a fan shape and is provided with triangular lower tongs teeth, and the lower part of the lower tongs lip is a flat-circular hollow hand lever, wherein, the bottom end and both right and left sides of which are separately provided with a fai< 8 > hexagonal hole, a fai< 6 > hexagonal hole and a square hole. The upper tongs lip forms a bent hook shape and the front end of the upper tongs lip is provided with triangular upper tongs teeth mutually matched with the lower tongs teeth, and the upper tongs lip is installed in a groove on one side of the lower tongs lip through a minor axis and can rotate by winding the minor axis; both ends of the spring are separately connected with the upper and the lower tongs lips. The utility model has the advantage of convenient operation and can be used for screwing all 1/2-11/2 pipe fittings.

Description

Novel pipe vice

The utility model relates to a kind of pipe vice that is exclusively used in installation or removal screwed connection pipe fitting.

Pipe vice is the instrument that is exclusively used in installation or removal screwed connection pipe fitting, has a wide range of applications in the installation exercise of hot-water heating pipeline or water for industrial use pipeline.Pipe vice of the prior art mainly is made of upper clamp lip, spring leaf, adjusting nut, lower clamp lip and flat screw mandrel, turns adjusting nut and can make the openings of sizes of pipe vice change, reach the purpose of rotating the different-diameter pipe fitting.According to pipe vice specification series in the prior art, turn the pipe vice that 1/2 "～11/2 " pipe fitting commonly used need use 7 kinds of specifications of 8 "～36 ".In real work, each operative employee will be equipped with the pipe vice of large, medium and small three kinds of specifications wherein at least and be used to turn the adjustable wrench of fastening nut, and whenever twists a kind of all necessary pipe vice aperture of adjusting of pipe fitting of specification.Therefore, pipe vice of the prior art not only specification is many, carries and use also inconvenience.

The purpose of this utility model promptly is to design a kind of novel pipe vice, makes it to adjust span of jaw automatically, thereby significantly reduces the specification and the handled easily of pipe vice.

To achieve these goals, the utility model is designed to lower clamp lip and upper clamp lip respectively fan-shaped with crotch shape and utilize a minor axis to link to each other, and when pipe fitting feeding jaw, upper clamp lip can rotate around minor axis, thereby adjusts span of jaw automatically.When twisting pipe fitting, the triangle clamp tooth on upper clamp lip and the lower clamp lip can be held pipe fitting with a firm grip, utilizes the handle reinforcing of lower clamp lip bottom can turn pipe fitting.Like this, utilize a kind of pipe vice of specification can twist all specification pipe fittings of 1/2 "～11/2 ".Be described in further detail below in conjunction with the technical characterictic of specific embodiment the novel pipe vice of the utility model.

Accompanying drawing 1 is the structural representation of the novel pipe vice of the utility model;

Accompanying drawing 2,3 is respectively handle lower bottom view and side view.

With reference to the accompanying drawings 1,2,3, the novel pipe vice of the utility model mainly is made of upper clamp lip, lower clamp lip and spring.Lower clamp lip 1 is fan-shaped and has triangle lower clamp tooth 2, the one side has the groove that is used to install upper clamp lip and spring, its underpart is oblate hollow handle 3, the bottom of handle 3 has φ 8 hexagonal holes 4 that are used for twisting six square nuts, and its both sides have the square hole 6 that is used for twisting φ 6 hexagonal holes 5 of six square nuts and is used for twisting plug.Upper clamp lip 7 is a crotch shape, and its front end has the triangle upper clamp tooth 8 of working in coordination with lower clamp tooth, is installed in the groove of lower clamp lip one side by minor axis 9 and can rotates around minor axis 9, and its outside have a depression bar 10.Spring 11 is installed in the groove of lower clamp lip one side, and it links to each other with lower clamp lip 1 with upper clamp lip 7 respectively at two ends up and down.During use, utilize depression bar that jaw is opened and pipe fitting is fed jaw, when by the handle reinforcing pipe vice being pressed down, upper clamp tooth and lower clamp tooth are held pipe fitting with a firm grip, can turn pipe fitting.During outer push strut, help to make upper clamp tooth and the lower clamp tooth pipe fitting of holding with a firm grip.

The utility model is simple in structure, and is easy to operate, utilizes a kind of pipe vice of specification can twist all specification pipe fittings of 1/2 "～11/2 " and can utilize the hexagonal hole of handle bottom and both sides and square hole to twist corresponding nut and plug.Therefore, the utility model is particularly suitable for as pipe vice.

Claims

1, a kind of pipe vice that is exclusively used in installation or removal screwed connection pipe fitting is characterized in that being made of upper clamp lip, lower clamp lip and spring; Described lower clamp lip is fan-shaped and has the triangle lower clamp tooth, and the one side has the groove that is used to install upper clamp lip and spring, and its underpart is oblate hollow handle, and handle bottom and both sides have φ 8 hexagonal holes, φ 6 hexagonal holes and square hole; Described upper clamp lip is a crotch shape, and its front end has the triangle upper clamp tooth of working in coordination with lower clamp tooth, is installed in the groove of lower clamp lip one side by minor axis and can rotates around minor axis, and its outside has a depression bar; Described spring is installed in the lower clamp lip one side groove, and it links to each other with lower clamp lip with upper clamp lip respectively at two ends up and down.
