Abstract

The utility model discloses an extendable pipeline connector which is used for connecting pipelines. The utility model comprises a hugging turn body which is consisted by a metal jacket layer and a rubber inner layer. One end of the two hugging arms of the hugging turn body is turnable connected with a shaft pin, the other end of the two hugging arms is provided with an overlapping interface and a locking structure. The extendable pipe connector has good commonality, and high scalability. Therefore, the utility model is suitable for situations that the same caliber pipes are provided with different errors. Especially, the utility model can be conveniently installed under normal pressure without any measures. Therefore, the utility model solves the problem that the seepage of the pipeline needs to be repaired by reducing pressure or stopping water supply. Thus, the great loss and problem which are brought to water supply enterprises and vast users are solved as well.

Description

The Drawability pipe jointer

The utility model relates to a kind of connection set that is used for pipeline, particularly a kind of Drawability pipe jointer.

Water is Source of life, yet carries the water supply network of this important substance, is factor because of standing acid and alkali corrosion and Nature and Man for a long time but, causes pipe leakage often to take place.Bring greatly loss and trouble to water undertaking, also damaged users' interests simultaneously.Always each water undertaking has taked various means and method to shorten the water stopping time that causes because of repairing when pipe first-aid, but still this link of repairing of can't avoiding cutting off the water.Because the water-supply structure of present domestic use is comparatively of poor quality, particularly tubing girth and the diameter at same bore differs bigger, therefore, now domestic there is no a kind of can be with regard to adapting to the existing error of various tubing at the product of not cutting off the water supply, rushing to repair under the situation of step-down.

The purpose of this utility model is to provide a kind of highly versatile for the deficiency that solves above-mentioned technology, can need not the Drawability pipe jointer that adopts any measure conveniently to install under normal pressure.

In order to achieve the above object, a kind of Drawability pipe jointer of the utility model design, it comprises embraces the circle body, it is characterized in that embracing the circle body is made up of metal-coating layer and rubber internal layer, two arms, one end of embracing the circle body is rotatably connected by pivot pin, and the other end of two arms is provided with lap interface, locking mechanism.In order to guarantee that when the circle body is embraced in locking the interface of connected pipe does not leak, described locking mechanism is made up of plural locking hole and locking screw on its each arm, and locking screw is embraced the circle body by locking hole locking.

Drawability pipe jointer highly versatile, scalability that the utility model obtains are bigger, adapt to the occasion of the different errors of caliber pipe material of the same race fully; Particularly can under normal pressure, need not to adopt any measure conveniently to install, solve because of pipe leakage needs to keep in repair thus by step-down, the link of cutting off the water and brought the difficult problem of very big loss and trouble for water undertaking and users.As adopt stainless steel cladding material and nontoxic rubber inner layer material, and both can reach intensity height, corrosion-resistant, light, easy installation, again can leakage proof, nonhazardous, be applicable to that pipelines such as various water supply, air feed or fuel feeding use.

Fig. 2 is the arm structural representation that is rotatably connected.

In conjunction with the accompanying drawings the utility model is further described below by embodiment

Embodiment:

As shown in Figure 1, a kind of Drawability pipe jointer of present embodiment design, it comprises embraces circle body 1, embracing circle body 1 is made up of metal-coating layer 2 and rubber internal layer 3, metal-coating layer 2 adopts stainless steel material to make, rubber internal layer 3 adopts the nontoxic rubber material, as shown in Figure 2, two arms, 4 one ends of embracing circle body 1 are rotatably connected by pivot pin 5, the other end of two arms 4 is provided with lap interface 6, locking mechanism 7 is in order to guarantee that when circle body 1 is embraced in locking the interface of connected pipe does not leak described locking mechanism 7, be made up of three locking holes 8 and locking screw 9 on its each arm, locking screw 9 is embraced circle body 1 by locking hole 8 lockings.
