Description

A packing for faucet pipe coupling capable of adjusting the angle of the faucet

The present invention relates to a packing, and more particularly, to a packing which can be installed at a point where a water supply is connected to a water supply pipe to allow water supply to be prevented from flowing out, To a packing for a connecting part.

A water supply unit is a unit installed on a wall in an indoor unit, and receives water from a water supply source through a pipe, and finally discharges the water through a faucet or a drain pipe.

1, includes a connection pipe 10 connecting a pipe for supplying water and a faucet for discharging the water. The connecting body 10 is connected to a pipe for supplying water to one side and to a water outlet on the other side, and is disclosed in Japanese Patent Application Laid-Open No. 10-2010-0063411 entitled " .

Here, the connecting body 10 as described above is typically embedded in the wall. And is installed inside the body case 20 embedded in the wall, and is firmly fixed at the installed position, so that it is firmly installed without any movement and supports the power reception.

The connection body 10 is connected through a power supply and a screw connection. At this time, packing is used to prevent leakage of water. The coupling tube is threadedly engaged with the coupling body 10 so that the coupling body is formed with a step inside the coupling body 10, So that water is not leaked by being pressed and installed between the jaws.

Here, in order to prevent the water from leaking out, the packing must be strongly pressed. For this purpose, the water is formed in the water faucet and the waterproofing is tightened until the end of the waterproofing pipe is not moved further. However, at this time, when the coupling is completed, the power reception may stop at a position rotated more than the desired position. This is because there are many variables such as the elasticity of the packing, the length of the thread, etc., and it is considerably difficult to make the receptacle reach the correct position in a state where the coupling is completed.

Therefore, in order to bring the water faucet to the correct position, the water faucet is often rotated more than necessary or rotated to a necessary degree or less. However, in the case of rotating more than necessary, excessive pressure is applied to the packing to cause a problem of breakage. On the other hand, in the case where the packing is rotated below the required level, the packing may not be pushed under proper pressure.

Particularly, in order to make the rotation more than necessary, the compressed packing shrinks and the length thereof is reduced and the diameter thereof has to be expanded naturally. In the pipe, the expansion of the packing is limited by the inner wall, so that the shrinkage of the packing is extremely limited. , It was inevitable that the faucet could reach the correct position by rotating it below the required level. As a result, the packing can not secure a sufficient degree of watertightness, and the possibility of occurrence of a watering-out phenomenon is increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to solve the above problems, and to provide a water pump system capable of sufficiently tightening a packing at a point where pipes are connected, To be fixed to the base plate.

According to the present invention, a packing is provided to maximize the degree of contraction of a length of a packing while minimizing the expansion of a diameter even if an external force is applied to the packing in a state in which watertightness is secured. By adopting the packing at the point, the water receptacle can be fixed at the correct position while the water receptacle is sufficiently secured and the water receptacle can be further tightened or loosened to achieve the above object.

According to the present invention, it is possible to adjust the position by further rotating the water supply in a state in which the watertightness is sufficiently secured, so that a useful effect of increasing the convenience of the pipe connection is caused.

In the present invention, in order to make it possible to adjust the fixing position by tightening the water supply even when the water tightness is secured by fully pressing the packing at the point where the pipe is connected, particularly, the water receiving point, And a plurality of shrinking grooves 140 are formed on the outer circumferential surface of the through hole 120. The shrinking grooves 140 are formed at the point where the water receptacle is connected to the water receptacle, We propose a packing for the connecting part that makes it possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to FIGS. 2 to 10.

First, the packing 100 according to the present invention will be described.

2 to 4 are perspective views showing various embodiments of a packing according to the present invention. Figs. 5 to 7 are cross-sectional views showing various embodiments of a packing according to the present invention. Fig. to be.

The packing 100 according to the present invention is formed in a cylindrical shape. And is made of a material having elasticity such as rubber, so that it can be shrunk to some degree by an external force. A through-hole 120 is formed in the center of the body along the longitudinal direction. And the water can pass through the through passageway 120 or pass through the pipe. It is a well-known basic constitution generally seen as above.

Shrinking grooves 140 are formed on the outer circumferential surface of the body. And grooves are formed with a predetermined depth and width along the circumference of the body in the circumferential direction. The shrinkage groove 140 is smaller than the diameter of the packing 100, and when the packing 100 is contracted due to an external force applied to the body 100, the shrinkage groove 140 contracts first. Therefore, the extension of the diameter of the portion other than the shrinking groove 140 is minimized while maximizing the shrinkage of the length of the body.

A plurality of such shrinkage grooves 140 may be formed as needed. It is possible to adjust the number of formed bodies in order to maximize the degree of shrinkage or the length of the body. As the number of the shrinking grooves 140 increases and the degree of shrinkage increases as the depth and width increase, the airtightness decreases as the number of the shrinking grooves 140 increases. Accordingly, the length of the body 100 of the packing 100 To be formed in an appropriate number.

When the plurality of shrinking grooves 140 are formed, the depth and width of the respective shrinking grooves 140 may be different from each other. As the depth and width of the shrinking grooves 140 are greater and the depth of the shrinking grooves 140 is more easily shrunk due to the external force, the depth and width of the shrinking grooves 140 are variously varied. That is, when an external force is applied, the shrinking groove 140 having a deep depth contracts first and then the shrinking groove 140 having a shallow depth is contracted. At this time, as the width of the shrinking groove 140 increases, As a result, by forming the shrinkage grooves 140 as described above, the body of the packing 100 can be sequentially contracted according to the degree of external force applied thereto.

Here, the shrinkage groove 140 may have a sloped surface 142 inclined downward toward the center of the body. At this time, the inclined surface 142 is formed to a position deeper than the other contraction grooves 140. Therefore, the diameter of the body is sequentially decreased at the point where the shrinkage groove 140 is formed, so that the degree of shrinkage according to the degree of the external force can be adjusted. This configuration can be more advantageously adopted when the shrinking grooves 140 are formed in a plurality of.

The packing 100 according to the present invention described above can be recessed as shown in FIG. 3 or convex as shown in FIGS. The center portion is formed concave or convex. When the central portion of the rear surface of the body is formed concave or convex, the thickness gradually increases from the rear end of the body (concave shape) or the body diameter sequentially increases (convex shape) There is a phenomenon that the degree of abrupt contraction and the degree of contraction are gradually decreased. As a result, the degree of contraction due to external force increases toward the rear end of the body. Accordingly, the degree of shrinkage of the body of the packing 100 can be controlled.

Hereinafter, a state in which the packing 100 according to the present invention is installed and used at a point where a water receptacle is connected will be described as an example.

FIG. 8 is a view illustrating a state where a packing according to the present invention is installed at a point where a water receptacle is connected, and FIGS. 9 and 10 are views showing an example in which a packing according to the present invention is contracted by an external force.

As shown in the figure, the packing 100 according to the present invention can be installed at a point where the water receptacle 300 is connected. And the water receptacle 300 is screwed to one end of the connecting body 10 installed in the wall. At this time, a coupling pipe 320 may be formed in the water receiving unit 300 so that the coupling pipe 320 is screwed to the connecting body 10. In addition, the connection body 10 is embedded in the wall while being protected by the body case 20, and a predetermined space may be formed in advance to allow the body case 20 to be installed on the wall. However, ) Are connected to each other is not limited to the above-described configuration, and any configuration can be used as long as the pipe and the pipe are connected.

The coupling tube 320 has a thread formed on the outer circumferential surface thereof. The coupling body 10 has a thread formed on the inner circumferential surface thereof. The coupling body 10 has an enlarged diameter of a point connected to the coupling tube 320 A tuck is formed naturally inside. The packing 100 according to the present invention is installed between the distal end of the coupling tube 320 and the jaw formed inside the coupling body 10 so that the coupling tube 320 is inserted and screwed into the coupling body 10, do.

When the water receptacle 300 is rotated while the packing 100 is installed as described above, the coupling pipe 320 rotates and pushes the rear end of the packing 100 to be tightened. The packing 100 pushed by the coupling pipe 320 stops its progression as it touches the jaw. In this state, the water receiver 300 is further rotated to tighten the packing 100 to secure water tightness.

If the water receptacle 300 is not stopped at a desired position in a state in which the watertightness is sufficiently secured, the water receptacle 300 may be further rotated so that the maximum diameter of the body of the packing 100 is not significantly changed, 100 and the shrinkage grooves 140 are further shrunk so that the water receptacle 300 can be further rotated. Therefore, the position of the water receptacle 300 can be adjusted to a desired degree.
