Description

`` APPARATUS FOR CONNECTING EARTHQUAKE-PROOF PIPE WITH INCREASED TENSILE FORCE AND EASY CONNECTION}

The present invention relates to a seismic type one-touch insert pipe connecting device that absorbs contraction and expansion of a pipe. Specifically, an O-ring and an elastic member providing watertightness and elasticity are installed between a hook holder having a hook, and the pipe is fixed. By allowing the hook to move left and right along the inclined surface in the hook holder, seismic design is possible to cope with the contraction and expansion of the pipe. The present invention relates to a seismic type one-touch insert pipe connection device that absorbs contraction and expansion of a pipe to support a pipe through a connection pipe and a hook holder to provide an axial force to cope with uneven settlement.

In general, the pipe connecting device is mainly used as a means for connecting and fixing the pipe and the pipe while maintaining the airtightness of the pipe, and has various forms such as straight, elbow, T-shaped, and cross shape depending on its structural shape. .

Conventional pipe connecting apparatuses require a separate fixing means such as a screw connection or a snap ring to weld the connection portion of the pipe in order to improve the airtightness and the coupling property. Therefore, the piping connection operation is difficult and the assembling process is increased, have.

In addition, the conventional stainless steel pipe for general plumbing used in such a pipe connection device is so thin that it is difficult to form a screw, as well as welding in the construction site, additional process such as using a dedicated press or expansion pipe is added. There is discomfort that should be.

Various pipe connecting devices have been developed to solve this problem.

In relation to the pipe connecting device, Korean Patent Publication Nos. 10-2009-0106296 and 10-2009-0039630 have been disclosed.

As shown in FIG. 1, a connection for a pipe, which is Korean Patent Publication No. 10-0984839, has a pair of pipes for accommodating a pipe 10 having an annular groove 111 and an inclined portion 112 formed along an inner circumferential wall. The stopper member 120 and the stopper member 120 which are provided in the pair of body 110 to move along the body 110 and the inclined portion 112 and stop the movement of the pipe 10 are elastically radially. The first elastic member 130 for supporting, the second elastic member 140 for elastically supporting the stop member 120 in the axial direction, the inlet 113 to prevent foreign matter from entering the pair of the body (110) It includes a cover member 150 provided in).

And, Korean Laid-Open Patent Publication No. 10-2009-0039630, the connecting device of the pipe as shown in Figure 2 pipe (1) (2) installed in the position connecting the mutual connection pipe (110); Inserted and coupled to both ends of the pipe connector 110 in a state interposed between the pipe connector 110 and the pipe (1) (2), a plurality of jaw mounting holes at regular intervals along the outer peripheral surface Jaw holder 120 is formed; The pipe (1) (2) is rotatably mounted in the jaw mounting hole (121) and pressed against the inner wall surface (110a) of the pipe connector (110) and inserted into the jaw holder (120). Jaw 130 for fixing; An elastic member 140 is installed inside the pipe connector 110 to elastically support the jaw 130. In this case, a backup ring 150, a spring support ring 160, and a seal ring 170 are installed in the pipe connector 110.

However, the pipe connection has to form a slope in the body, and the pipe connecting device has to manufacture a structurally complex jaw holder and a jaw respectively, so that the production time and assembly time are increased, resulting in an increase in production cost. There is this.

In addition, the pipe connecting device and the pipe connecting device can move the pipe inward when an external shock (earthquake, etc.) or inequality occurs, but the movement of the pipe is limited by the stop member or the jaw to the outside, so that This causes breakage, which causes gas or water to leak out.

In addition, the connecting device for the pipe and the connecting device of the pipe has a problem that the tension member is relatively weak because the number of fixing points is limited because the stop member and the jaw fix the pipe through line contact.

Hereinafter, the assembling process of the seismic type one-touch insertion pipe connection device for absorbing the contraction and expansion of the pipe according to the present invention will be described in detail with reference to the accompanying drawings.

10 and 11 are explanatory views for explaining the assembling process of the seismic type one-touch insertion pipe connecting device for absorbing the shrinkage expansion of the pipe according to the present invention, Figures 12 to 15 are shrinkage expansion of the pipe according to the present invention It is explanatory drawing for demonstrating operation | movement of the seismic type one-touch insertion pipe connection apparatus which absorbs water.

First, as shown in FIG. 10, the hook holder 240 into which the O-ring guide 220, the O-ring 230, the spring 250, and the hook 260 are inserted into the pipe inlet 213 of the connector 210. ) And the elastic member 270 are sequentially inserted.

In this state, as shown in FIG. 11, the end of the pipe inlet 213 of the connecting pipe 210 is bent to form a fixing jaw 215 to block the internal components from being separated.

And, if you look at the installation process, as shown in Figure 12 when inserting the pipe (P) into the fixing jaw 215 of the connecting pipe 210, because the spring 250 supports the hook 260 hook The pipe P end is caught by 260.

When the pipe P is continuously inserted, as shown in FIG. 13, as the spring 250 is compressed, the hook 260 is moved inward along the first inclined surface 243 of the hook holder 240, and then the spring 250. ) Is no longer compressed to support the hook holder 240, so that the inner diameter of the hook 260 is enlarged to allow the pipe P to penetrate the hook 260.

Subsequently, the pipe P is sequentially inserted through the hook holder 240, the O-ring 230, and the O-ring guide 220, and inserted into the pipe receiving groove 211, as shown in FIG. 14.

In this state, when a tensile force is generated in the pipe P by hydraulic pressure, external shock (earthquake, etc.) or inequality, the pipe P coupled with the hook 260 is moved outward as shown in FIG. 15.

Then, the hook 260 and the pipe P move, that is, the second inclined surface 261 of the hook 260 moves along the first inclined surface 243 of the hook holder 240, and then the inclined portion of the hook 260 is inclined. As the inner diameter gradually narrows, the plurality of contact protrusions 263 press-fit the pipe P to block further movement and resist tensile force.

As a result, the hook 260 is moved a predetermined distance from the hook holder 240 to the outside with the pipe P, all the shock is absorbed by the elastic member 270, the hook holder 240 and the hook 260 and Since the pipe P can move a little further to the outside, it can cope with both tension and vibration by the expansion of the pipe P.

On the contrary, when the pipe P, which has been moved outwardly by water pressure and vibration, expands and contracts inwardly according to the temperature change, as shown in FIG. 14, the hook 260 is moved inwardly along the hook holder 240. Since the shock is absorbed by the spring 250 and the O-ring 230, both the contracted expansion and vibration of the pipe P can be coped with.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood, however, that the invention is not to be limited to the specific forms thereof, which are to be considered as being limited to the specific embodiments, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims. .
