Abstract

The utility model discloses a pipe-bending plier. It includes a supporting plate, a block that revolves around the plate, a pin installed at the center of the plate, a pin fixed in the block, a connecting plate fixed between the two pins mentioned above and grooves on the surface of the cylindrical surface, a corresponding groove on the block surface which faces to the supporting plate. The utility model provides a special pipe-bending plier used in construction and decoration and has the strengths of high productive quality and efficiency, meanwhile avoiding the leakage.

Description

Pipe-bending spanner

Technical field

The utility model relates to a kind of pipe-bending spanner.

Background technology

In building construction and decorative engineering, can use many pipelines, for example: copper pipe, aluminum pipe, PAP etc., these pipelines do not have special-purpose pipe crimping tool when operation at present, and not only labour intensity is big, inefficiency, but also can bring the pipeline cabling lack of standardization, defectives such as materials waste, even can cause hidden danger such as pipeline seepage, bring severe impairment to construction quality.

Summary of the invention

The purpose of this utility model is: a kind of pipe-bending spanner is provided, and simple in structure, easy to use for the architecture and decoration engineering provides special-purpose pipe crimping tool, can the lift line quality, increase work efficiency, avoid the pipeline seepage.

The technical solution of the utility model is: a kind of pipe-bending spanner, include by dish and can lean around and coil the briquetting that rotates, axle center by dish is inserted with by the dish bearing pin, be inserted with on the briquetting with by dish bearing pin parallel briquetting bearing pin, by being provided with connecting plate between dish bearing pin and the briquetting bearing pin, by the side of dish be fixed with by coil bearing pin vertical by coiling handle, be fixed with the press handle vertical on the briquetting with the briquetting bearing pin, by the front portion of dish be provided with by coiling the parallel pin of bearing pin, by at least one groove on the face of cylinder of dish, briquetting towards the face by dish be provided with by coiling corresponding groove; Described cross section by the groove on dish and the briquetting is semicircle; Bending forms described pin by protracting also by the dish handle; Described by coiling in the skewback of being pruned near quilt on the position of pin, so that inserted by bend pipe.

The utility model has the advantages that:

1. the utility model provides special-purpose pipe crimping tool for the architecture and decoration engineering, with the lift line quality, increases work efficiency, and avoids the pipeline seepage.

2. when using, be inserted between two grooves by dish and briquetting, and pipe end is inserted into pin and by between coiling, pulls press handle, make briquetting, can make pipe curve required angle around leaning on disc spins by bend pipe.

Description of drawings

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the front view by dish;

Fig. 3 is the vertical view by dish;

Wherein: 1 by dish; 2 briquettings; 3 by the dish bearing pin; 4 briquetting bearing pins; 5 connecting plates; 6 by the dish handle; 7 press handle; 8 pins; 9 grooves; 10 grooves; 11 skewbacks.

The specific embodiment

Embodiment: as Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, a kind of pipe-bending spanner, include by dish 1 and can lean around and coil 1 briquetting 2 that rotates, axle center by dish 1 is inserted with by dish bearing pin 3, be inserted with on the briquetting 2 with by the parallel briquetting bearing pin 4 of dish bearing pin 3, by being provided with connecting plate 5 between dish bearing pin 3 and the briquetting bearing pin 4, by dish 1 side be fixed with by coil bearing pin 3 vertical by coiling handle 6, be fixed with the press handle 7 vertical on the briquetting 2 with briquetting bearing pin 4, by dish 1 front portion be provided with by coiling the parallel pin 8 of bearing pin 3, bending forms pin 8 by protracting also by dish handle 6, by coiling 1 in the skewback 11 of being pruned near quilt on the position of pin 8, so that inserted by bend pipe, by at least one groove 9 on the face of cylinder of dish 1, briquetting 2 towards be provided with by dish 1 face with by dish 1 corresponding groove 10, by coil 1 and briquetting 2 on groove 9 and 10 cross section be semicircle.

During use, be inserted into by between dish 1 and two grooves 9 and 10 of briquetting 2 by bend pipe, and pipe end be inserted into pin 8 with by coiling between 1, pull press handle 7, make briquetting 2 around rotating by coiling 1, can make pipe curve required angle.The utility model provides special-purpose pipe crimping tool for the architecture and decoration engineering, and is simple in structure, easy to use, can the lift line quality, increase work efficiency, and avoid the pipeline seepage.
