Abstract

The utility model discloses a pipe wrench used for disassembling a threaded connection piece, which comprises a pipe wrench handle (1), wherein the pipe wrench handle (1) is connected with a pipe wrench head part (3) by a regulation hand wheel (2); and one end of the pipe wrench handle (1), which is connected with the pipe wrench head part (3), is fixedly provided with a pipe wrench tooth plate (5). The pipe wrench used for disassembling the threaded connection piece is characterized in that teeth (4) of the pipe wrench head part (3) are in a V shape. The pipe wrench used for disassembling the threaded connection piece has the advantages of simple structure and small investment, the problems of high tooth surface abrasion speed, big possibility of skidding due to small chance of tooth contact, and high cost are solved, and meanwhile, the safety is improved.

Description

A kind of pipe vice that is used for the threaded connector dismounting

Technical field:

The utility model relates to the Work tool technical field, is a kind of pipe vice that is used for the threaded connector dismounting specifically, is mainly used in the fast quick-detach of piercing mandrel plug.

Background technology:

At present, lean on push rod in steel pipe's production middle punch machine top to be threaded together, install, the essential use of dismounting pipe vice, use the pipe vice of 1200mm common, standard to implement always at present; This pipe vice moulding early, and the stressed flank of tooth is the plane, has only two teeth with contacting of top pipe wrench skids in the unloading process because the wearing and tearing of tooth cause, the one, increased the replacing frequency of pipe vice, increased cost; The 2nd, pipe vice skids in the process of dismounting top, can the staff bring potential safety hazard.

Summary of the invention:

The purpose of the utility model is the deficiency that overcomes prior art, and a kind of pipe vice that is used for threaded connector dismounting is provided, and solves mainly that existing pipe vice is prone to skid, cost high and the staff is existed problem such as safety factor.

In order to achieve the above object; The utility model is achieved in that a kind of pipe vice that is used for the threaded connector dismounting; It comprises the pipe wrench handle; Through adjusting handle tube connector clamp head part, at the fixing pipe wrench tooth plate of an end of pipe wrench handle tube connector clamp head part, its special character is that the tooth of pipe wrench head is " V " font on the pipe wrench handle.

Compared with present technology the described a kind of pipe vice that is used for the threaded connector dismounting of the utility model has following good effect: 1, simple in structure, and small investment; 2, solved the problem that tooth surface abrasion is fast, cost is high; 3, solve toe joint and touched less, be prone to the problem of skidding; 4, reduce field personnel's labour intensity, eliminated potential safety hazard, improved security.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

The specific embodiment:

In order to understand better and to implement, the utility model is elaborated below in conjunction with accompanying drawing.

Embodiment 1; Referring to Fig. 1; According to designing requirement, " V " font is processed at tooth 4 positions of pipe wrench head 3, by prior art pipe wrench head 3 is installed in pipe wrench handle 1 through adjusting handle 2 again; One end of pipe wrench handle 1 tube connector clamp head part 3 is pipe wrench tooth plate 5 fixedly, forms a kind of safety durable and dismantling device.

Claims

1. one kind is used for the pipe vice that threaded connector is dismantled; It comprises pipe wrench handle (1); Pipe wrench handle (1) is gone up through adjusting handle (2) tube connector clamp head part (3); At the fixing pipe wrench tooth plate (5) of an end of pipe wrench handle (1) tube connector clamp head part (3), the tooth (4) that it is characterized in that pipe wrench head (3) is " V " font.
