Background

The pipe fittings such as the water pipe and the like can be broken when being subjected to external force, aging and other reasons, the water pipe in a house can be completed through the following steps of firstly, closing the gate; cutting off the broken part of the water pipe; thirdly, the water pipe at the water outlet end is disassembled to enable the water pipe to move left and right; fourthly, mounting a two-way connector and the like on the water pipe at the water inlet end in a water hose, glue and other modes; fifthly, pulling the water pipe at the water outlet end, and installing the water pipe on the connecting piece in a water belt, glue and other modes to complete the connection of the water inlet end and the water outlet end; sixthly, fixing the water pipe at the water outlet end again; the procedure is very complicated.

In addition, if the water supply pipe or the water discharge pipe of the outdoor community is broken, the water pipes on two sides of the broken water supply pipe or the water discharge pipe cannot be dragged, so that the water supply pipe or the water discharge pipe cannot be installed by connectors such as a two-way connector, and the water supply pipe or the water discharge pipe can be connected only by using a professional hot melting device, and is troublesome to use, long in time and high in cost.

Disclosure of Invention

The invention aims to overcome the defects and provide a quick pipeline connecting device.

The invention adopts the following technical scheme:

a pipeline quick connecting device as shown in fig. 1 to 3, comprising a connecting pipe, wherein the right end of the connecting pipe is provided with a connecting section, and the connecting section is used for entering a first pipe fitting and tightly attaching to the inner wall of the first pipe fitting; the sleeve enters from the right end of the connecting pipe, is sleeved outside the connecting pipe and can move outside the connecting pipe, and one end of the sleeve is provided with a sleeve connecting section which can enable the second pipe fitting to enter and be tightly attached to the outer wall of the second pipe fitting; and the limiting connecting device is used for limiting the sleeve so that the right end of the sleeve is tightly attached to the left end of the connecting pipe when the sleeve moves towards the left end of the connecting pipe.

Preferably, the limiting connection device comprises a sealing ring protruding from the outer wall of the left end of the connection pipe and a sleeve sealing ring protruding inwards from the inner wall of the right end of the sleeve; the sealing ring enters and is tightly attached to the sleeve sealing ring.

Preferably, the sealing ring is provided with a fillet

Preferably, PVC glue is coated at the position where the sealing ring enters and is tightly attached to the sleeve sealing ring.

Preferably, the connecting section is used for entering the first pipe fitting and smearing PVC glue at the position tightly attached to the inner wall of the first pipe fitting; the sleeve connecting section can enable the second pipe fitting to enter and is coated with PVC glue at the position tightly jointed with the outer wall of the second pipe fitting; PVC glue is coated at the close joint of the right end of the sleeve and the left end of the connecting pipe.

Preferably, the middle section of the outer wall of the connecting pipe is also provided with a limiting ring.

The invention has the beneficial effects that: the invention has low manufacturing cost, can quickly carry out butt joint maintenance on the fractured pipeline without disassembling pipe fittings and professional hot melting devices, has simple use and short installation time, greatly reduces the maintenance cost and improves the maintenance efficiency.

Detailed Description

In order to make the purpose and technical solution of the present invention clearer, the present invention is further described with reference to the accompanying drawings and embodiments:

the left and right directions in the present invention are for convenience of explanation only and are not intended to limit the present invention; a quick pipe connection device as shown in fig. 1 to 3, comprising a connection pipe 1, wherein a connection section 11 is arranged at the right end of the connection pipe, and the connection section 11 is used for entering a first pipe 31 and tightly attaching to the inner wall of the first pipe 31; the sleeve 2 enters from the right end of the connecting pipe 1, is sleeved outside the connecting pipe 1 and can move outside the connecting pipe 1, one end of the sleeve 2 is provided with a sleeve connecting section 21, and the sleeve connecting section 21 can enable the second pipe fitting 32 to enter and be tightly attached to the outer wall of the second pipe fitting 32; and the limiting connecting device is used for limiting the sleeve 2, so that when the sleeve 2 moves towards the left end of the connecting pipe 1, the right end of the sleeve 2 is tightly attached to the left end of the connecting pipe 1.

Preferably, the limiting connection device comprises a sealing ring 12 protruding from the outer wall of the left end of the connecting pipe 1 and a sleeve sealing ring 22 protruding inwards from the inner wall of the right end of the sleeve 2; the seal ring 12 enters and snugly abuts the sleeve seal ring 22.

Preferably, the sealing ring 12 is provided with rounded corners to facilitate smooth intersection with the sleeve sealing ring 22.

Preferably, PVC glue is applied to the position where the sealing ring 12 enters and closely fits the sleeve sealing ring 22.

Preferably, the connecting section 11 is used for entering the first pipe 31 and smearing PVC glue at the position where the connecting section is tightly attached to the inner wall of the first pipe 31; the casing connecting section 21 can enable the second pipe fitting 32 to enter and is coated with PVC glue at the position tightly jointed with the outer wall of the second pipe fitting 32; PVC glue is coated at the close joint of the right end of the sleeve 2 and the left end of the connecting pipe 1.

Preferably, 1 outer wall interlude of connecting pipe still is equipped with spacing ring 13, and when can avoiding linkage segment 11 to insert first pipe fitting 31, the effort is too big for linkage segment 11 inserts the length overlength of first pipe fitting 31, and when leading to sleeve pipe 2 to move left, is guaranteeing that sealing ring 12 gets into and closely laminates under the condition of sleeve pipe sealing ring 22, the butt joint of bushing segment 21 and second pipe fitting 32 can't be realized.

The using method of the invention comprises the following steps:

firstly, cutting off the broken parts of the two pipe fittings (the first pipe fitting 31 and the second pipe fitting 32) and controlling the distance between the first pipe fitting 31 and the second pipe fitting 32 (too short to enable the invention to cut off the first pipe fitting 31 or the second pipe fitting 32, and too long to connect the two pipes by using the two-way pipe fitting to shorten the distance between the two pipes).

Secondly, the sleeve 2 enters from the right end of the connecting pipe 1 and is sleeved outside the connecting pipe 1, the sleeve is placed between the first pipe 31 and the second pipe 32, the outer wall of the connecting section 11 is coated with PVC glue, and the PVC glue is inserted into the first pipe 31 to be tightly attached to the inner wall of the first pipe 31.

Third, all scribble PVC glue at second pipe fitting 32 right-hand member and sealing ring 12, bushing segment 21 moves to connecting pipe 1 left end for second pipe fitting 32 right-hand member gets into and closely laminates in bushing segment 21, and sealing ring 12 gets into and closely laminates bushing sealing ring 22 simultaneously, accomplishes the water pipe butt joint.

The invention has the beneficial effects that: the invention has low manufacturing cost, does not need to disassemble the pipe fitting, can quickly carry out butt joint maintenance on the broken pipeline without a professional hot melting device when the pipe fitting can not be pulled, has simple use and short installation time, greatly reduces the maintenance cost and simultaneously improves the maintenance efficiency.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the present invention.
