Description

Pipe inserting and screwing connector

Technical Field

The utility model relates to a connecting piece is twisted in pipeline inserting.

Background

At present, the fluid supplies such as gas and water in domestic and foreign markets are all conveyed by adopting metal and plastic pipelines, the connection of the metal and plastic pipelines is mainly realized by interconnecting accessories such as straight-through parts, elbows, tee joints and reducing parts, the straight-through parts are basic parts of other accessories and are evolved from the straight-through parts, in the engineering construction and installation process, the metal pipes are connected by welding or threading, so that a large amount of waste of manpower and material resources is caused, the production efficiency is low, a plurality of problems such as poor sealing and complex maintenance exist in the using process generally, the plastic pipes are installed by gluing or hot melting, toxic gas is discharged in any mode, particularly, the hot melting causes physical injury to operators, the leukemia is easy to be caused by long-term contact, and the environmental pollution is easy to cause. At present, in order to meet the requirement of fast rhythm, various quick connector quick connecting pieces appear, the sealing of the quick connecting pieces on the market adopts an O-shaped graph, a sealing surface is in an annular linear shape, the sealing area is small, the number of the leakage parts is large, the process structure is complex and unreasonable, the price is high, the leakage is limited by conditions, the safety factor is low, and the leakage is easy.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the utility model provides a connecting piece is twisted to pipeline insertion overcomes not enough of welding, hot melt, gluing etc. that original pipeline connecting piece ubiquitous, has realized "one inserts one and twists", has strengthened sealing performance, has improved work efficiency.

In order to solve the technical problem, the utility model discloses the technical scheme who takes is: the pipeline inserting and screwing connecting piece comprises a stabilizing pipe, outer conical sealing hoses, bulges are arranged in the middle of the stabilizing pipe, grooves are formed in the middle of the outer conical sealing hoses, the outer conical sealing hoses are connected with the stabilizing pipe mutually, inner conical thrust pipes are connected to two ends of the stabilizing pipe respectively, inner conical surfaces of the inner conical thrust pipes are matched with outer conical surfaces of the outer conical sealing hoses, compression nuts are arranged on the outer portions of the inner conical thrust pipes, the inner conical thrust pipes can rotate freely in the compression nuts, the inner conical thrust pipes are fixedly connected with the compression nuts through pins, and the compression nuts compress the inner conical thrust pipes.

Further, the inner diameter of the external conical sealing hose is slightly larger than the outer diameter of the pipeline pipe.

After the technical scheme is adopted, the utility model discloses the technological effect who brings is: the utility model adopts long pipe sealing, increases the sealing surface, realizes the pipe installation without welding, without threading, the plastic pipe without gluing and hot melting, overcomes the defect that the iron plastic pipe can not be mixed and connected in the accessory use of the prior art, realizes 'one insertion and one twisting', leads the pipelines to be connected into a whole, achieves the safety, long-term and no leakage, solves the sealing problem of the pipelines, leads the pipe and the pipe fitting to be combined into a whole, improves the sealing performance, and achieves better sealing effect; the old parts can be repeatedly used, waste is reduced, resources are saved, non-professionals can operate the device, the device is simple, convenient and quick to install, manpower and material resources are saved, installation cost is saved, and working efficiency is improved.

Detailed Description

The principles and features of the present invention will be described with reference to the drawings, which are provided for illustration purposes only and are not intended to limit the scope of the present invention.

According to the figures 1-14, the pipe inserting and screwing connector comprises a stabilizing pipe 3, an outer conical sealing hose 4, a protrusion is arranged in the middle of the stabilizing pipe 3, a groove is arranged in the middle of the outer conical sealing hose 4, the outer conical sealing hose 4 is connected with the stabilizing pipe 3, the protrusion of the stabilizing pipe 3 is matched with the groove of the outer conical sealing hose 4 to play a stabilizing role, inner conical thrust pipes 2 are respectively connected to two ends of the stabilizing pipe 3, the inner conical surfaces of the inner conical thrust pipes 2 are matched with the outer conical surfaces of the outer conical sealing hose 4, so that the sealing pipe is gradually contracted, and the sealing effect of the outer conical sealing hose 4 is enhanced; including 2 outsides of toper distance tube are equipped with gland nut 1, but interior toper distance tube 2 free rotation in gland nut 1, interior toper distance tube 2 passes through pin 5 fixed connection with gland nut 1, and gland nut 1 compresses tightly interior toper distance tube 2, has improved the leakproofness, and the effect of pin 5 is when dismantling the pipe fitting, and gland nut 1 links as an organic wholely with interior toper distance tube 2, more convenient dismantlement.

Preferably, the inner diameter of the external conical sealing hose 4 is slightly larger than the outer diameter of the piping material.
