Description

Connecting structure for sleeve

The present invention relates to a pipe coupling structure of the sleeve, and more particularly, to a pipe coupling structure of the sleeve that can be quickly and conveniently coupled to the pipe inserted into the sleeve.

In general, plumbing equipment is closely related to human daily life. Not only does it supply drinking water to homes or industrial water to factories, but it also discharges used wastewater to the outside. Piping can be broadly divided into industrial piping including industrial piping such as building piping, which is in charge of water supply, hot water supply, heating and cooling, drainage, and exhaust, and crude oil transportation piping, dust collector piping, and power plant piping.

Pipes used in the above pipes are used by selecting the steel pipe, synthetic resin pipe, cast iron pipe, concrete pipe, copper pipe, etc. according to the temperature, pressure, the nature of the transport object in the pipe, and usually formed in a constant length or shape It was connected to each other and used.

Meanwhile, in order to install the pipe as described above, a sleeve capable of connecting or penetrating two pipes is used. Before installing concrete, etc. to install facility pipes, a sleeve having a diameter larger than that of facility pipes is buried in advance. Later, it was easy to expand or repair the facility piping, and even after the sleeve was buried, it was possible to prevent the inflow of groundwater or invasion of moisture through the wall.

At this time, when joining the pipes formed in a certain length and shape to the sleeve, cover the outer peripheral surface of the pipe connecting portion and then wrap the pipe connection band around the coupling, or clamped by using a separate pipe connection bracket The method of combining was applied. However, the pipe piping structure as described above was inconvenient to combine the pipes according to various conditions such as the use of the pipe and the construction environment, and it was not easy to separate the pipes from the sleeve when repairing or replacing the pipes due to aging of the pipes. Because of the inconvenience of the separation work could not be carried out quickly.

Another method of coupling the sleeve was to grab the outer circumferential surface of the pipe to be inserted and inserted into the sleeve to prevent the grab ring from coming off in the reverse direction.

This has the advantage of easily coupling the pipe to be inserted, but when it needs to be replaced or repaired, it has to be separated by penetrating the pipe in the direction of insertion without being discharged in the reverse direction due to the grabbing.

In this case, in order to separate the inserted pipe, it is necessary to secure a space through which the pipe can penetrate, and there was a need to separate all the coupling devices located at the tip of the pipe. In addition, there is a problem that can not be separated in one space because the sleeve is usually buried in the bottom, for example, in the case of pipes installed on the wall after the pipe through space secured to secure the space in one side wall space The construction work was very inconvenient and inefficient because it was necessary to remove the pipe and move it to the other space and newly join the pipe, and there was a need to improve it.

The present invention was devised to solve the above problems, and more particularly, it is possible to easily install and quickly install the pipe inserted into the sleeve, and at the same time completely solve the problems such as leaking by sealing the combined part completely. The purpose is to obtain a piping coupling structure of the sleeve.

In order to achieve the above object in the present invention, in the sleeve fixedly coupled to the pipe inserted into the inside, the inside of the sleeve is composed of a plurality of elastic pieces bent at a predetermined angle is formed, the pipe is separated in the reverse direction We propose a pipe joint structure of the sleeve that can prevent the separation.

As described above, the present invention can be quickly installed by easily coupling the pipes to the sleeve, so that the construction work is convenient and the construction time can be shortened, thereby improving the productivity of the construction work, and replacing and replacing them due to aging and defects. The maintenance work is convenient, so it has utility in management aspect.

In addition, by grabbing the outer circumferential surface of the pipe inserted into the sleeve strongly, grabbing can be prevented from being severely separated due to external factors such as defects or strong water pressure of the coupling portion, thereby preventing the separation. It is to have an effect.

As shown in FIG. 1, the sleeve 100 is generally formed in a hollow shape, and is capable of coupling a pipe 200 embedded in a concrete wall or floor, and is generally in contact with water according to long-term use. It is formed of the same material as plastic to prevent corrosion.

In this case, as shown in FIG. 2, the inlet may be penetrated by both inlets, and the pipe 100 may be inserted thereinto, and the two pipes 200 may be inserted and connected to each other.

Meanwhile, as illustrated in FIGS. 3 to 5, the pipe 200 is inserted into and coupled to the inside of the inlet of the sleeve 100.

At this time, the inlet of the sleeve 100 is configured with a grab ring 106 to fix the pipe 200 is inserted into the inside, the grab ring 106 is a plurality of elastic pieces having a shape such as tooth teeth. 107 is formed to be bent at a certain angle in the insertion direction of the pipe 200, it is possible to strongly bite the outer peripheral surface of the pipe 200 is inserted into it.

More specifically, when the pipe 200 is inserted into the sleeve 100, the tooth-shaped elastic pieces 107, which are bent at a predetermined angle, are strongly held by pressing the outer circumferential surface of the pipe 200, and the force As a result, the elastic piece 107 penetrates a part of the outer circumferential surface of the pipe 200 so that the pipe 200 is firmly fixed by allowing the pipe 200 to never fall out in the reverse direction.

At this time, the sleeve 100 is formed as the inlet is wider than the diameter of the pipe 200 so that the pipe 200 can be inserted smoothly as shown in Figure 4, the pipe 200 is inserted therein The pipe jaw 112 is formed to prevent excessively pushed up during the coupling process, so that the pipe 200 is not pushed up any more when the pipe 200 is inserted to an appropriate depth.

On the other hand, the sealing jaw 114 and the supporting jaw 116 are formed sequentially below the pipe jaw 112, the fluid flowing out through the pipe 200 in the sealing jaw 114 is sleeve 100 The rubber ring 102 that can seal the coupling portion is prevented from leaking into the gap space generated due to the combination with).

In addition, the support jaw 116 is formed with a rubber ring support 104 that can support the rubber ring 102 seated on the closed jaw 114, the rubber ring support 104 is bent at a predetermined angle The support piece 105 is formed, the end of the bent portion of the support piece 105 abuts and supports the rubber ring 102, the edge is seated on the support jaw 116, thereby stabilizing It will be to support the rubber ring 102.

At this time, the rubber ring 102 and the rubber ring support 104 is formed on the upper portion of the grab ring 106, the angle at which the support piece 105 is bent is limited to the movement of the elastic piece 107 The elastic piece 107 is preferably bent at an angle greater than the bent angle so as not to be.

In addition, the grab ring support 108 supporting the grab ring 106 is located at the bottom of the grab ring 106 at the lower portion of the grab ring 106.

At this time, the grabbing support 108 is formed with a screw projection along the outer peripheral surface, the sleeve 100 is formed with a screw groove corresponding to the screw projection along the inner peripheral surface, the screw groove of the sleeve 100 And the screw projection of the grabbing support 108 is to be coupled in a screwing manner.
