Description

[0001] PIPE CONNECTING APPARATUS OF ONE-TOUCH TYPE [0002]

More particularly, the present invention relates to a one-touch pipe connection apparatus capable of easily connecting pipes and assuring an inexpensive manufacturing cost, excellent watertightness, fixing force, durability, and the like.

In general, pipes and pipe joints of various sizes and shapes are used to induce the fluid to a certain path. As the connection method according to the combination, there is a welding method which shows excellent durability and watertightness at the connection part when the metal pipe is connected, And a URF (Union Rubber Ring Fitting) method in which a rubber packing is brought into close contact with a pipe.

Here, the welding method as described above requires a certain space for the welding work for connecting the tubular body. In addition, there is a problem that the maintenance work is very inconvenient when a defect occurs in the tubular body after welding due to welding. For example, If the connection is made through the welding method, the welded portion must be formed along the outer periphery of the tube. Therefore, it is necessary to secure the working space by the welding, and since the tube is welded through the pressure ring, It is very difficult to separate and re-install the pipe between the pipes, and when pipes having different sizes are to be connected according to the method of flange, welding, etc., expensive pipe joints must be provided separately. Therefore, Korean Patent No. 10-0899461 (hereinafter referred to as "Patent No. 1" ) And Patent No. 10-0927198 (hereinafter referred to as " Registered Patent 2 "). However, the piping connection apparatuses of the above-mentioned Patent No. 1 and No. 2 are fixed to the tube by tightening the bolts exposed to the outside. It is impossible to guarantee the watertightness and the fixing force in the connection between the pipes when the impact is applied to the bolt due to the method of tightening the bolts. It is troublesome and time consuming.

In addition, the above-mentioned bond bonding method can easily connect the piping by using a dedicated bond suitable for the plastic. Therefore, it is necessary to follow the hardening time according to the structure of the lowest price of the product or the standard , It is not possible to recycle joint pipe or pipe, it is not applicable to connection of heterogeneous plastic or metal pipe, and it is not compatible. Also, it is difficult to check indoor air pollution due to use of bond, precise construction condition, There is a problem such as dirtiness.

In the URF system, a strong physical force is applied to the rubber packing in order to adhere the rubber packing to the pipe. For example, a rubber packing is disposed in a space between the spirally coupled body and the cap, Because the rubber packing is attached to the piping at the time of bonding, the troublesome work of tightly tightening the body and the cap with the tool is necessary. Therefore, in the case of the plastic product, since the substantial physical stress is applied to the body and the cap, And the durability is deteriorated at the same time.

In order to solve the problems of the conventional piping jointing method as described, the present applicant invented the registered patent No. 10-0977308 (hereinafter referred to as 'registered patent 3'), but the cost of the product is lowered, There is still a need for research into various aspects in order to enable smooth diffusion of technology.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art described above, and it is an object of the present invention to provide a one-touch piping connection device capable of easily connecting pipelines and at the same time having a low manufacturing cost and a structure for ensuring stable watertightness, The purpose is to provide.

In order to attain the above object, the present invention provides a water treatment system comprising: an insertion portion for inserting a pipeline, the insertion portion having an inner perforation for inserting a tube along an outward direction from the center, And the extension portion includes a plurality of fitting grooves disposed at an inner side surface of the synthetic resin body at predetermined intervals and at regular intervals; A rubber packing disposed at a step of the synthetic resin body to prevent water supplied to a pipe inserted to the fitting portion from leaking; A ring-shaped support member having one side thereof supporting the rubber packing and the other side extending to a part of the fitting groove; A rod-shaped metal member inserted into the fitting groove of the synthetic resin body and formed in a straight line section and a downward inclined slope continuously along the opposite direction of pipe insertion; And a protruding rib at an outer end of the synthetic resin body to allow a pressure spring to be disposed in a predetermined space provided between an end of the synthetic resin body and the protruding rib, A member; And the teeth are disposed at predetermined intervals on the push member side so as to move along the straight section and the inclined surface of the metal member installed in the synthetic resin body. When the pipe is inserted into the synthetic resin body, the teeth are supported on the inclined surface by the restoring force of the pressing spring, And a contact member which is in close contact with the pipe.

Hereinafter, a one-touch pipe connecting apparatus according to the present invention will be described with reference to the drawings.

FIG. 1 and FIG. 2 are exploded and assembled perspective views showing a one-touch pipe connection apparatus according to the present invention, and FIGS. 3 to 5 are cross-sectional views illustrating an operation principle of a one-touch pipe connection apparatus according to the present invention.

The one-touch pipe connection apparatus according to the present invention basically comprises a synthetic resin body 10 into which a pipe 1 is inserted, a rubber packing 20 disposed in the synthetic resin body 10 to prevent leakage, a rubber packing 20 Like support member 30 for supporting the synthetic resin body 10 in a predetermined space of the synthetic resin body 10, a rod-shaped metal member 40 fitted in the synthetic resin body 10, A push member 50 which is connected to the push member 2 and which is moved in a linear direction by the press spring 2 and which is inserted into the synthetic resin body 10 while being supported by the metal member 40, And a contact member 60 for fixing the piping 1 or allowing the piping 1 to be separated.

The synthetic resin body 10 has an insertion portion 11 into which the pipe 1 is inserted along the outward direction from the center in a form in which the inside of the synthetic resin body 10 is insertable for insertion of the pipe 1, In particular, the extension 12 includes a plurality of fitting grooves 12-2 disposed on the inner surface thereof at regular intervals with the step 12-1.

The synthetic resin body 10 is basically injected into one set of molds. In the case of the fitting groove 12-2, the mold body can be formed along the inner surface of the synthetic resin body 10 without applying post- 10 as well as being made into a cylindrical body integrally formed with no other parts that may affect the physical properties of the synthetic resin body 10, The resistance strength of the material itself can be maintained as it is.

The structure of the above-described synthetic resin body 10 is not limited to a straight line as shown in the drawing, but also an elbow type, a T-type, a branched type (a shape in which a plurality of piping can be additionally installed on both sides in a straight line) And the like.

The rubber packing 20 provided on the synthetic resin body 10 has a ring shape and is disposed in the step 12-1 of the expansion part 12 to be fluidly supplied through the pipe 1 by self- 6, the wing portion 21 is inclined to the central portion of the synthetic resin body 10 by the water pressure so that the wing portion 21 is prevented from leaking to the outside of the pipe 1. [ So that water tightness can be ensured even when vibration is applied to the pipe 1. [

More specifically, according to the structure of the rubber packing 20 having the wing portion 21, the ring-shaped portion prevents water from leaking from the pipe toward the step 12-1 side, Thereby preventing leakage of water in the space between the packings 20, wherein the wing portion 21 provides greater watertightness against vibration than conventional O-ring packings because of the wide range of movement that can be flexibly moved.

The ring-shaped support member 30 is a cylindrical body through which the pipe 1 can pass, and one side of the ring-shaped support member 30 supports the rubber packing 20 so that the rubber packing 20 does not deviate from the range where the step 12-1 is formed. So that the metal member 40 is extended to a portion of the fitting groove 12-2 so that it is supported by the push member 50 described in detail below and the metal member 40 is not separated from the fitting groove 12-2.

The metal member 40 is inserted into the fitting groove 12-2 of the synthetic resin body 10 and the linear section 41 and the downwardly inclined surface 42 are formed on the surface of the pipe 1 facing the pipe 1, A strong water pressure is generated in the fitting portion 11 of the synthetic resin body 10 and the water pressure is applied to the push member 20 via the rubber packing 20 and the ring- The contact member 60 provided on the push member 50 is supported by the inclined surface 42 when the pipe member 50 is transmitted to the pipe member 50 and the pipe member 1 is pressed with the contact member 60, The metal member 40 can be prevented from being dislodged while preventing the extension portion 12 from being damaged while the metal member 40 can be manufactured inexpensively and mass-produced through press working, It becomes an important factor.

The cylindrical push member 50 is provided with a protruding rib 51 at an outer end thereof to enable the pressing spring 2 to be disposed in a predetermined space provided between the end of the synthetic resin body 10 and the protruding rib 51 And is connected to the synthetic resin body 10 so as to be movable only in the direction of insertion or removal of the pipe 1. In the state of being connected to the synthetic resin body 10 through the example described below or otherwise, The contact member 60 is also moved along the straight line 41 and the slope 42 of the metal member 40 in response to the linear movement path in which the pressing member 2 is pressed or the restoring force of the pressing spring 2 moves, The other part of the extension portion 12 and the contact member 60 are not brought into contact with each other.

If the cylindrical push member 50 is rotatably connected to the synthetic resin body 10, the contact member 60 is also rotated at the same time, so that the inclined portion which is in contact with the metal member 40 must be circular as a whole, unlike the metal member 40, The structure is accompanied by a large-cost work such as a process of manufacturing a ring-shaped metal, a process of inserting the metal into a mold and an insert, and a process of forming an inclined portion in the inserted metal.

Since the pressing spring 2 is disposed between the push member 50 and the synthetic resin body 10 so that the moving path of the push member 50 is utilized as a space for disposing the pressing spring 2, The entire length of the present invention can be reduced as compared with the case where the pressing spring 2 is disposed inside the synthetic resin body 10.

The contact member 60 is disposed at a predetermined interval on the push member 50 side so as to move along the straight section 41 and the inclined surface 42 of the metal member 40 provided in the synthetic resin body 10, When the piping 1 is inserted into the synthetic resin body 10, the tooth 61 is supported by the inclined surface 42 by the restoring force of the pressure spring 2, (1) It is possible to fix the piping while pressing the outer circumferential surface.

More specifically, the push member 50 is provided with an insertion hole 52 into which the contact member 60 is inserted, and the contact member 60 is provided with an inclined surface 60a so that the teeth 61 are in close contact with the outer circumferential surface of the pipe 1, The protrusion piece 62 supported by the protrusion 42 may be provided so that when the pipe 1 is drawn into the synthetic resin body 10 as shown in Figures 3 to 5, When the push member 50 moves to the center side of the synthetic resin body 10 in the state where the protruding teeth 61 and the pipe 10 are in close contact with each other and when the contact member 60 is positioned in the straight section 41, The push member 50 is lifted up to the space between the member 50 and the metal member 40. When the tooth 61 is positioned in the insertion hole 52 as described above, The projecting piece 62 is supported on the inclined surface 42 while being pushed in the direction opposite to the insertion direction of the fastener 1, The water pressure acting in a state in which the pipe 1 is connected is transmitted to the push member 50 through the rubber packing 20 and the ring type support member 30 as shown in Fig. do.

7 and 8, as one example of the structure for preventing the push member 50 from rotating and being separated from the synthetic resin body 10 as described above, A through hole 53 is formed between the hole 52 and the protruding rib 51 and a fixing protrusion 12-3 is provided on the extended portion 12 or the metal member 40 of the synthetic resin body 10 The fixing protrusion 12-3 may be positioned in the through hole 53 when a part of the push member 50 provided with the contact member 60 is bent and inserted into the synthetic resin body 10, The push member 50 moving to the protruding rib 51 does not fall out of the synthetic resin body 10. The through hole 53 is formed in the push member 50 in the direction of the protruding rib 51 from the position where the fixing protrusion 12-3 is located, The synthetic resin body 10 may be inserted into the body 10 at a predetermined distance.

The fixing protrusions 12-3 can be positioned in the through holes 53 in the process of forcibly inserting the push member 50 into the synthetic resin body 10 so as to bend the push member 50. In this case, The pressing protrusion 12-3 may be attached to the push member 50 because the pressing protrusion 12-3 may be pressed against the synthetic resin body 10 and the fixing protrusion 12-3 may be positioned in the through hole 53. [ And the through holes 53 are formed between the plurality of insertion holes 52 and the through holes 53 and further between the thickness receptacle 54 and the through holes 53. [ When the push member 50 provided with the contact member 60 is pushed into the synthetic resin body 10 by the resilient hook 55 having the sliding surface gradually tilted upwards The through holes 53 and the fixing protrusions 12-3 are arranged at the shortest distance to each other while allowing the protrusions 12-3 to pass therethrough When the pushing member 50 is rotated in a specific direction when the pushing member 50 is rotated, the fixing protrusion 12-3 can be easily positioned in the through hole 53 on the sliding surface of the resilient hook 55 having the bending property, The elastic hook 55 pressed by the protrusion 12-3 returns to the original state and the push member 50 can move only in the linear direction without being separated from the synthetic resin body 10 together with the contact member 60 .

In order to prevent the problem that the foreign matter is interposed between the synthetic resin body 10 and the gap between the synthetic resin body 10 and the push member 50, the maintenance work is troublesome in the future, And a lid part 56 extending toward the synthetic resin body 10 along the end periphery.

In addition, since the insertion restriction ribs 13 are provided on the inner side of the synthetic resin body 10 so as to allow the pipe 1 to be inserted by the same length on both sides, the pipe 1 can be inserted only by a predetermined length, 10) piping disposed on both sides can be fixed to the same length.
