Abstract

The utility model discloses a hardened and toughened pipe tong, and the aim of the utility model is to provide a technology having the advantages of simple structure, easy production and high efficiency. The utility model comprises tong body (1) of a pipe tong, a handle (2) of the tong body, a handle hole (3), a bottom surface (4) of the tong body, a tong back part (5) of the tong body, fixing seats (6) of telescopic nuts, which are arranged on the back part of the tong body, a tong hook on the back part of the tong body, which is in series connected with an outer casing seat (7) of a tunnel, a tong hook on the back part of the tong body, which is in series connected with a tunnel (8), tong teeth (9) connecting with the tong body heads, hook connecting bodies (10) of the pipe tong, hook bending heads (11) of a hook body, tong teeth (12) which are arranged at the inner sides of the hook bending hooks, hook tails (13) of the hook body, telescopic forward and backward threads (14) of the hook body, and telescopic forward and backward nuts (15) of the hook body. The utility model changes the tong teeth (9) connecting with the tong body heads and the tong body (1) of a pipe tong into an integrative body structure. The utility model can be widely used for installing and rotating workpieces, such as cylindrical building materials, etc., and is the replacing production for an original pipe tong.

Description

Hardened and toughened pipe tongs

Technical field

The utility model be a kind of relate to cylindrical be the tool using that main construction material workpiece is installed and removed, installed, more particularly, it is a kind of pipe vice.

Background technology

To ending at present, all pipe vices assemble by tetrad, inside and outside two pincers tooth position systems adopt middle and high carbon steel manufacturing and form through high-frequency quenching, make the pincers tooth that high-frequency quenching forms with middle and high carbon steel, hardness quenched easy fracture high, easy defective, that hardness has been quenched low is easy to wear, practicality is not good, so both are difficult to take into account.

Summary of the invention

The purpose of this utility model is for overcoming deficiency of the prior art, provide a kind of simple in structure, easily manufactured, the utility model technology that practical function is better.

The technical scheme that its technical problem that solves the utility model adopts is:

The utility model hardened and toughened pipe tongs comprises pipe vice caliper 1, caliper handle 2, delthyrium 3, caliper bottom surface 4, the caliper pincers back of the body 5, the flexible nut holder 6 of the caliper back of the body, caliper back-up tong hook string dress tunnel outer shell base 7, caliper back-up tong hook string dress tunnel 8, caliper head disjunctor pincers tooth 9, pipe vice is pulled hook coupler body 10, pulls hook coupler body hook heads 11, pulls the inboard pincers of hook hook heads tooth 12, pulls hook coupler body hook tail 13, pulls hook hook body flexible advance and retreat screw thread 14 and pulled the flexible advance and retreat of hook hook body nut 15; Caliper head disjunctor pincers tooth 9 is an overall structure with pipe vice caliper 1.

The beneficial effects of the utility model are:

1, the utility model changes the split insert structure of the caliper head disjunctor in former workpiece pincers tooth 9 inserts on pipe vice caliper 1 and is made as overall structure, makes its more reasonable structure, makes easylier, and practicality is better;

2, the utility model is simple in structure, makes easyly, acts on hugely, and social benefit is obvious.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

On the pipe vice caliper 1 of accompanying drawing 1, accompanying drawing 2, be respectively equipped with caliper handle 2, trigger piece hole 3, caliper bottom surface 4, the caliper pincers back of the body 5, the flexible nut holder 6 of the caliper back of the body, caliper back-up tong hook string dress tunnel outer shell base 7, caliper back-up tong hook string dress tunnel 8 and the caliper head disjunctor pincers tooth 9 of conjoined structure; Pull to be respectively equipped with on the hook coupler body 10 at pipe vice and pull hook coupler body hook heads 11, pull the inboard pincers of hook hook heads tooth 12, pull hook coupler body hook tail 13 and pull the flexible advance and retreat of hook hook body screw thread 14; Pipe vice is pulled hook coupler body 10 string be loaded in the caliper back-up tong hook string dress tunnel 8, be fixed in and pull on the flexible advance and retreat of the hook hook body screw thread 14 pulling the flexible advance and retreat of hook hook body nut 15 spinnings then.

Claims (1)

1, a kind of hardened and toughened pipe tongs, comprise pipe vice caliper (1), caliper handle (2), delthyrium (3), caliper bottom surface (4), the caliper pincers back ofs the body (5), the flexible nut holder (6) of the caliper back of the body, caliper back-up tong hook string dress tunnel outer shell base (7), caliper back-up tong hook string dress tunnel (8), caliper head disjunctor pincers tooth (9), pipe vice is pulled hook coupler body (10), pull hook coupler body hook heads (11), pull the inboard pincers of hook hook heads tooth (12), pull hook coupler body hook tail (13), pull hook hook body flexible advance and retreat screw thread (14) and pull the flexible advance and retreat of hook hook body nut (15), it is characterized in that: caliper head disjunctor pincers teeth (9) are overall structure with pipe vice caliper (1).
