As a typical application example of connecting the pipe, there is a case of fitting by connecting the indoor unit and the outdoor unit of the air conditioner. As a conventional method of connecting and fitting such a pipe, a welding method may be applied, but the welding method is not preferable because it consumes a lot of time and damages the pipe.

Meanwhile, brass is mainly used as a material of the conventional connector due to its excellent physical properties and beauty. In the case of using a brass material, the fitting could be performed not only by welding but also by expansion method. However, free cutting brass, which is mainly used as a connector material, contains lead and cannot meet the ROHS standard. Therefore, there is a demand for a material of a connector that can replace brass.

Pipes used for various purposes are also expensive due to the increase in copper prices, and there is a need for materials that can replace copper. Under these circumstances, there is a need for a pipe that can replace copper and a connector suitable for the pipe of the material.

On the other hand, when aluminum is used as the material of the connector, it is not preferable because expensive brazing and high frequency argon welding should be applied when fitting by welding. In addition, the expansion method of increasing the diameter of the pipe, there is a problem that is difficult to be applied due to the characteristics of the ductility good aluminum. As a result, there is a growing demand for a connector capable of sufficiently preventing leakage of a material flowing in the inside of the pipe while using aluminum as the material of the pipe.

1 is a perspective view of a connector according to a first embodiment, and FIG. 2 is a cross-sectional view taken along the line A-A of FIG. 1.

1 and 2, the connector 1 according to the present embodiment includes a left member 2 into which the left tube 4 is inserted, a right member 3 into which the right tube 5 is inserted, and a left tube (4) and the right tube (5) is both inserted and receives the force from the left member (2) and the right member (3) in the fitting operation, but the means includes a media member (7) which is provided in a fixed position relative to.

In addition, the connector 1 further includes a left parallel member 8 that performs the action of picking up the left side pipe 4, and a right parallel member 9 that performs the action of picking up the right side pipe 5. The left parallel member 8 may be formed as a separate article from the left member 2 and may be accommodated in the left member 2. The right parallel member 9 may be formed as a separate article from the right member 3 and may be accommodated in the right member 3.

The outer surface of the tube (4) (5) may be provided with a coating layer of a resin material as an example. Corrosion of the pipes 4 and 5 can be prevented by the coating layer. Of course, it is also possible to omit the coating layer.

The left member 2, the right member 3, the intermediate member 7, the left parallel member 8 and the right parallel member 9 are all provided in a hollow shape with an empty inside and the via In the space there is inserted a tube (4) (5). In addition, the intermediate member 7 is inserted into the left member 2 and the right member 3.

In the present exemplary embodiment, the left tube 4, the left member 2, the right tube 5, the right member 5, the left parallel member 8, and the right parallel member 9 are referred to as drawings. The tube 4 is the first tube, the left member 2 is the first member, the right tube 5 is the second tube, the right member 5 is the second member, the left parallel member is the first parallel member, the right parallel The member may be referred to as a second parallel member.

A cylindrical sheet 6 may be placed inside the medial member 7. The seat 6 is inserted with a portion of the left side tube 4 and the right side tube 5. The left tube 4 and the right tube 5 inserted into the seat 6 are in contact with a sealing portion (see 62 in FIG. 5) to be described later, and the contact surface is sealed to allow the fluid to flow through the tubes 4 and 5. Leakage is prevented.

With reference to the configuration of the connector described above will be described schematically the fitting work performed by the operator.

Tubes 4 and 5 are respectively inserted at left and right sides of the connector 1, and external force is applied to allow the left member 2 and the right member 3 to approach each other. When the left member 2 and the right member 3 are close to each other, the left side parallel member 8 and the right side parallel member 9 are pushed, and the parallel members 8 and 9 are left tube 4. And a force of pushing the left tube 4 and the right tube 5 while applying a pushing force toward the seat 6 to the right tube 5. The parallel members 8 and 9 are provided inside both the left member 2 and the right member 3. The action of picking up the pipes 4 and 5 by the parallel members 8 and 9 is an anti-leakage action to bring the contact surface between the seat 6 and the pipes 4 and 5 into close contact with each other. ) And the leakage preventing action of bringing the contact portion of the intermediate member 7 into close contact, and the contact of the parallel members 8 and 9 and the left and right members 2 and 3. As a result, it is possible to obtain an advantage that the reliability of the leakage preventing action is further improved.

On the other hand, since the left member 2 and the right member 3 perform the action of pushing the respective parallel members 8 and 9, it is said that the left and right members 2 and 3 are pushed together. You may. On the contrary, the intermediate member 7 corresponds to the left and right side members 2 and 3, that is, a counterpart that is not pushed against the pushing force of the pushing member. As a result, since the intermediate member 7 is provided in a fixed position with respect to the force pushed by the left and right members 2 and 3, the parallel member is formed by the interaction between the intermediate member 7 and the tube 4 and 5. (8) (9) can be carried out to pick up the tube (4) (5).

In the state that the action of the parallel member 8 and 9 is completed, the left member 2 and the right member 3 intersect with a direction approaching each other, and each of the members 2 and 3 facing each other. At least some of the corresponding surfaces may be in contact. When the surfaces of the left member 2 and the right member 3 which face each other contact each other, the operator can easily recognize that the fitting work is completed. In this case, the imperfection of the fitting work is eliminated and the operator can be prevented from applying external force to the connector unnecessarily. In FIG. 2, the left member 2 and the right member 9 are in contact with each other in a state where fitting is completed.

3 is a cutaway perspective view of the connector according to the first embodiment;

Referring to Figure 3, the configuration of the connector will be described in more detail.

First, the structure in which the left member 2 and the right member 3 approach each other will be described. The right end of the left member 2 is provided with a projection 21 is inserted into the recessed groove 31 of the right member (3). An inner side surface of the concave groove 31 is provided with a right fastening portion 32 which can be exemplified by a thread, and an outer side surface of the protruding portion 21 which can be fastened with a right fastening portion 32. 22 is provided.

When the left member 2 and the right member 3 are rotated to each other in the direction in which the threads of the respective fastening portions 22 and 32 are screwed together, the left member 2 and the right member 3 are approached to each other. I can move it. In this case, since only a single operation for rotating the left and right members 2 and 3 in the opposite directions is required, it is possible to reduce the labor of the operator and to improve the work time / efficiency.

The fastening structure of the left member 2 and the right member 3 is not limited to the configuration shown in the embodiment. Any configuration capable of performing the locking action after the movement and movement between the left and right members 2 and 3 can be applied as the fastening structure of the left and right members 2 and 3. However, since the operator can conveniently perform the fastening operation only by the operation of rotating the left and right members 2 and 3 in opposite directions, it may be desirable to provide a thread in terms of improving work convenience.

Inside and outside the protruding portion 21 and the concave groove 31, the left and right mediating member placing portions 23 and 33 on which the mediating member 7 is placed are provided. The left and right mediating member laying portions 23 and 33 are spaces for accommodating the medial member 7, and the medial member 7 is accommodated therein so that the left and right medial members 2 and 3 receive the medial member 7. It is a configuration for applying an external force toward. In the process of fitting the connector 1, at least a part of the intermediate member 7 overlaps the left member 2 and the right member 3 (protrusions 21 of the left member 2). And a part forming the concave groove 31 of the right member 3). Of course, the same is true even when the fitting of the connector 1 is completed. This is because the left and right members 2 and 3 must apply an external force to the intermediate member 7 while the left member 2 and the right member 3 are fastened. On the other side the part where the end of each tube 4, 5 is located in the intermediate member 7 is located inside the left member 2 or the right member 3.

The left and right side members 2 and 3 are provided with parallel member placing portions 25 and 35 on which the parallel members 8 and 9 are placed. On the left and right members 2 and 3 with respect to the fitting direction, the parallel member laying portions 25 and 35 and the intermediate member laying portions 23 and 33 are sequentially disposed.

According to the above description, with the intermediate member 7 in the center, it is understood that the parallel members 8 and 9 are also pushed toward the intermediate member 7 by a single rotational action.

As another example, the right side parallel member 9 may also be accommodated in the left side member 2 by adjusting the length of the left side member 2 or the length of the protrusion 21. In this case, the right side member 3 does not receive the right side parallel member 9, and causes the right side side member 2 to press the right side parallel member 9 in the fastening process with the left side member 2.

On the other hand, a sheet seating portion 71 on which the sheet 6 is placed is provided at substantially the center of the inner surface 74 of the intermediate member 7. The material of the sheet 6 may be exemplified by a polymer synthetic resin, Teflon, rubber, various synthetic resins, and the like, and may be selected from various materials capable of performing a sealing operation in contact with a metal.

The seat seating portion 7 is formed with a protrusion 72 for pressing the sealing portion (see 62 in FIG. 5) side of the seat 6. That is, the protrusion 72 may be formed at a position corresponding to the sealing portion (see 62 of FIG. 5) of the seat 6. The action of the protrusion 72 will be described later.

Inclined portions 73 are formed at both ends of the intermediate member 7. The inclined portion 73 is tapered so that the inner diameter thereof is reduced toward the inner side from both ends of the intermediate member 7. The inclined portion 73 contacts the parallel members 8 and 9 and exerts pressure on the parallel members 8 and 9 as a reaction of the pressure exerted by the parallel members 8 and 9.

4 is a cross-sectional view of the parallel member according to the first embodiment.

In FIG. 4, the left parallel member is disclosed as an example, but since the configuration of the left parallel member is the same as that of the right parallel member, only the left parallel member will be described below.

Referring to FIG. 4, the left side parallel member 8 includes a grip portion 81 for picking up a pipe and a stopper 85 for restricting relative movement of the intermediate member 7 in the fitting direction during the fitting process. Include.

The grip portion 81 includes a cylindrical portion 82 having a cylindrical outer surface and an inclined portion 83 having an outer surface inclined. The inclined portion 83 of the grip portion 81 contacts the inclined portion 73 of the intermediate member 7 during the fitting process. The inclined portion 83 is inclined to reduce the outer diameter of the grip portion 81 in a direction away from the cylindrical portion 82. A circumferential groove 84 is formed in the inner circumferential surface of the grip portion 81. The grip portion 81 is deformed by the groove 84 so that the pipe 4 and 5 can be smoothly picked up.

5 is a cross-sectional view of the sheet according to the first embodiment.

Referring to FIG. 5, the seat 6 according to the present exemplary embodiment includes a sealing part 62 in which end portions of the pipes 4 and 5 are in contact with each other to prevent leakage, and both sides of the sealing part 62. The left extension 63 and the right extension 64 are extended. When the tubes 4 and 5 are inserted through the extension portions 63 and 64, the inner diameter is set to be slightly smaller than the outer diameter of the tubes 4 and 5 to fix the tubes 4 and 5. Provisional assembly portions 65 and 66 are further provided.

The temporary assembly parts 65 and 66 may be provided in a shape in which at least two or more protrude from the inner diameter side of the extension parts 63 and 64 with respect to one extension part 63 and 64. Can be. As a result, the operation of inserting the pipes 4 and 5 is smoothly performed.

In the temporary assembly portion (65) 66, the end of the tube (4) 5 is inserted (that is, the right temporary assembly portion 66 is the right end and the left temporary assembly portion 65 is the left end) is inserted into the tube It may be provided inclined in the direction. Thus, the insertion of the tube can be guided more smoothly by guiding the insertion of the tube. On the contrary, the end from which the tube is pulled out from the temporary assembly parts 65 and 66 (that is, the right temporary assembly 66 is the left end and the left temporary assembly 65 is the right end) has no inclination or is inclined in the direction in which the tube is inserted. Can be provided. By such a shape, it is possible to prevent the pipes 4 and 5 inserted once from being detached.

When the operator inserts the pipes 4 and 5 on both sides of the connector with a predetermined length while the left and right members 2 and 3, the intermediate member 7, and the seat 6 are mounted, the pipes 4 and 5 Preliminary assembly of the tubes (4) (5) is completed on the sheet, more precisely on the extensions (63) (64), more precisely on the temporary assemblies (65) (66).

When the tubes 4 and 5 are inserted into the connector, the ends of the tubes 4 and 5 contact the ends of the sealing portion 62. At this time, when the pipes 4 and 5 are cut to a certain length for fitting the pipes 4 and 5, the outer peripheral surface of the ends of the pipes 4 and 5 is tapered. That is, the ends of the pipes 4 and 5 have an inclined surface. The inclined surface is formed to reduce the outer diameter toward the cut end side of the tube (4) (5). When the fitting operation is performed while the ends of the pipes 4 and 5 are in contact with the sealing part 62, the sealing part 62 is formed by the inclined surfaces of the pipes 4 and 5 so that the sheet ( 6) is pressed in a direction away from the center.

At this time, in the present embodiment, as the protrusion 72 of the seat seating portion 71 is provided at a position corresponding to the sealing portion 62, the sealing portion 62 is the pipe (4) (5) Even if pressed by the (), it is minimized that the sealing portion 62 is deformed by the protrusion (72). Therefore, the sealing part 62 is maintained between the pipes 4 and 5 so that sealing between the sealing part 62 and the pipes 4 and 5 can be smoothly performed. . Thus, leakage of liquid between the pipes 4 and 5 and the intermediate member 7 can be prevented.

When the coating layer is provided on the outer surface of the tube (4) (5), the sealing portion 62 is in contact with the coating layer and the tube (4) (5) at the cut surface portion of the tube (4) (5) By maintaining the state, the leakage of liquid between the coating layer and the tube (4) (5) can be prevented.

The provisional assembly is not limited to the structure and shape shown in the embodiment, so that the grooves in the circumferential shape is dug in both end surfaces of the sealing section, so that the end portions of the pipes 4 and 5 are fitted into the grooves. Various modifications can be made, such as the protrusions being not in the circumferential shape but also in the spaced apart protrusions arranged in the circumferential direction.

FIG. 6 is an enlarged view of a portion A of FIG. 2 and illustrates a state in which a parallel member is deformed. 6 shows that the coating layer is provided on the tube 4 and 5 as an example.

3 to 6, when the left and right members 2 and 3 approach each other, a sealing action between the pipes 4 and 5 and the intermediate member 7 and the left and right members 2 and 3 mutually. Explain.

6 shows an example of a left parallel member, but since the action of the right parallel member is the same as that of the left parallel member, only the left parallel member will be described below.

When the left and right side members 2 and 3 approach and the left side paralel member 8 is pushed toward the intermediate member 7 side (the right direction in FIG. 6), the grip portion 81 inclines the intermediate member 7. In contact with the portion 73, the inclined portion 73 of the intermediate member 7 is dug to deform the pipes 4 and 5. In order for the parallel members 8 and 9 to dig into the tubes 4 and 5, the tubes 4 and 5 are more tough than the parallel members 8 and 9. As described above, the inclined portion 83 is formed at the outer end of the grill portion 81 and the groove 84 is formed at the inner circumferential surface of the grip portion 81 in order to facilitate the digging operation.

When the grip portion 81 is pushed inward by the inclined portion 73 of the intermediate member 7, the grip portion 81 is deformed to the center side of the tube 4, 5, the tip portion of the grip portion 81 A portion of the tube 4, 5 that is in contact with is contracted in. That is, by the contraction of the tube (4) (5), the grip portion 81 performs the action of picking up the tube (4) (5).

The contracting action of the tubes 4, 5 is continuously carried out until the intermediate member 7 contacts the stopper 85 of the left parallel member 8. At this time, the first surface (85a) facing the intermediate member and the intermediate member 7 in the stopper 85 is in contact with, and the stopper 85 is located on the opposite side of the first surface (85a) In the state where the two surfaces 85b and the left member 2 are in contact with each other, the relative movement of the intermediate member 7 and the left parallel member 8 is prevented. In this case, the inclined surface 73 of the intermediate member 7 can no longer pressurize the grip portion 81, so that the grip portion 81 is no longer deformed. If the grip portion 81 is excessively deformed, the tube 4 is also excessively deformed, and the inner diameter of the tube 4 is reduced to hinder the flow of the fluid. However, according to the present exemplary embodiment, excessive deformation of the grip part 81 may be prevented by the intermediate member 7 by the stopper 85. That is, in this embodiment, the stopper 85 serves to limit the force applied to the grip portion 81 to a predetermined value.

As a result of this deformation of the tubes 4, 5, the contacts of the parallel members 8, 9 and the tubes 4, 5 are sealed.

When the intermediate member 7 comes into contact with the stopper 85, the surfaces of the left member 2 and the right member 3 which face each other come into contact as described above. When the surfaces of the left member 2 and the right member 3 which face each other in contact with each other in a fitting state are in contact with each other, even if vibration is directly applied or transmitted to the connector by the friction coefficient of the contact surface, the left member 2 and The right member 3 can be prevented from loosening.

When the surfaces of the left member 2 and the right member 3 which face each other come into contact with each other, the rotational force required to rotate the left and right members 2 and 3 increases rapidly, so that the left and right members 2 and 3 Leads to a state that can not rotate substantially. Thereby, the operator who performs the fitting work can conveniently know that the fitting work is finished by the contact of the left and right members 2 and 3. That is, the operator can easily know the end of the fitting work without using a separate torque wrench.

Although dependent on the pitch of the threads provided on the left and right fasteners 23 and 32, this remains within a limited angular range. As a result, the rotation angle required for the fitting operation is limited to a small rotation angle range, the limit angle can be conveniently known by the change in the force to be applied by the operator.

On the other hand, since the parallel member (8) (9) is formed as a separate article from the left and right members (2) and (3) is accommodated inside the left and right members (2) and (3), fitting work smoothly during fitting work If the refitting operation is not performed or the refitting operation is required, the refitting operation can be performed by replacing only the parallel member after separating the left and right members 2 and 3, thereby improving the recyclability (or repeatability) of the connector. It has the advantage of being.

7 is a flow chart of the connection method of the tube.

Referring to FIG. 7, the operator can check the pipe 4 on both sides of the connector in a state where the left and right members 2, 3, the intermediate member 7, the seat 6, and the parallel member 8, 9 are mounted. (5) is inserted (S1).

By way of example, after the parallel members 8, 9 are mounted on the left and right members 2, 3, the intermediate member 7 on which the seat 6 is mounted may be mounted on the left and right members 2, 3. Can be.

In a state where the tube is mounted, when the left and right members 2 and 3 are rotated in opposite directions to each other, the fitting work (connection work) of the pipe is terminated (S2).

As described, the fitting of the pipe can be completed by simple and simple operation, so that the efficiency and reliability of the operation can be further improved.

In another embodiment, the protrusion 21 is described as being in contact with the intermediate member 7, but is not limited thereto, and the recessed groove 31 and the intermediate member 7 are outside the intermediate member. Instead of the side, it may be provided outside the extension range of the intermediate member 7, that is, the outside of any one of the left and right members (2) (3). Even in this case, the basic action of making the left and right members 2 and 3 accessible to each other is the same.

8 is a cross-sectional view taken along the line A-A of FIG. 1 according to the second embodiment.

In the first exemplary embodiment, the gap between the left member 2 and the right member 3 does not exist while the fitting operation is completed, but in the second embodiment, the left member 2 and the right member ( 3) Even if there is a gap between them, we propose the idea to confirm the completion of fitting work.

In the description of the second embodiment, the description of the first embodiment shall be used unless otherwise specified.

Referring to FIG. 8, the protrusion 21 of the left member 2 is provided with a stopper 26 for contacting the right member 3 when the fitting work is completed. Since the surface intersecting the fitting direction in the stopper 26 is in contact with the right member 2, a gap between the left member 2 and the right member 3 may exist by the length of the stopper 26. . In this embodiment, the stopper 26 may be formed in one body with the left member 2. In this case, it can be easily guessed that the left member 2 can be described as contacting the right member 3 upon completion of the fitting operation.

As another example, the stopper 26 may be formed of an article separate from the left member 2 and may be fitted to the outside of the protrusion 21. For example, the stopper 26 may be formed in a ring shape, and a thread may be formed on an inner circumferential surface thereof so as to be fitted to the outside of the protrusion 21. In the present embodiment, the length of the right member 3 may be reduced by the length of the stopper. According to the present embodiment, the user can easily check whether the fitting work is completed visually without determining whether the fitting work is completed by using the gap gauge during the fitting work.

The first and second embodiments are embodiments for a connector for connecting a pipe and a pipe. The idea of the present invention can be applied not only to connecting a pipe and a pipe, but also to a device for connecting a pipe and a valve. In the description of the third embodiment, the description of the first embodiment shall be used unless otherwise specified.

The body 112 may be elastically deformed so as to be inserted into the medial member 7 at both sides of the medial member 7 and accommodated in the accommodation parts 76 and 77. For example, the body 112 is formed in an open ring shape. This can be completed by the body 112 by deforming the band-shaped plate to the ring shape, wherein the end of the band-shaped plate is unjoined.

Accordingly, in the state as shown in FIG. 11, the grip rings 110 and 111 are reduced in diameter in the process of being inserted into the intermediate member 7, and are aligned with the receiving portions 76 and 77 of the intermediate member 7. When the diameter is expanded again is accommodated in the receiving portion (76) (77).

As another example, as long as the diameter of the body 112 can be reduced, the body 112 may be formed in a closed ring shape, and the shape of the body 110 is not limited. Put it.

The plurality of pressing parts 113 are provided at positions spaced apart from each other in the body 112, and are provided in an elastically deformable form. Each pressing part 113 includes an extension part 114 extending from the body 112 and a contact part 115 extending obliquely from the extension part 114. The contact portion 115 may be formed in a quadrangular, triangular or trapezoidal shape, or the like, and may be formed such that a portion contacting the tubes 4 and 5 is pointed or rounded or corresponds to the shape of the outer circumferential surface of the tube. As another example, the grip rings 110 and 111 may not be provided with an extension, and the contact 115 may extend inclined directly from the body 112.

The contact portion 115 is inclined at an angle with the insertion direction of the tubes 5 and 5, and is positioned on the insertion path of the tubes 4 and 5 in a state accommodated in the intermediate member 7.

According to the present embodiment, two pipes of different materials may be connected by the connection pipe 420. In the present embodiment, the connecting pipe may be a pipe itself in advance, or some configuration such as a valve (the type is not limited), and in this embodiment, the type of pipe may be limited as long as the fluid may flow. Note that none. In this embodiment, the connecting pipe 420 serves as a counterpart to which the pipe is connected.

In the present specification, the tube 4 and 5 are primarily fixed by the grip ring, and the tube 4 and 5 are secondarily fixed by the parallel members 8 and 9. The ring may be referred to as a first grip member, and the parallel members 8 and 9 may be referred to as a second grip member.

In addition, in the present specification, it is described that a plurality of grip rings press each of the pipes 4 and 5, but on the other hand, pressing portions are formed on both sides of a single grip ring, and pressing portions on both sides of the left and right tubes respectively. Can be pressurized. In this case, the single grip ring may be seated on the seat seating portion of the intermediate member.

In addition, in the present specification, it has been described that the parallel member is formed as an article separate from the left member and the right member, but when the parallel member is used together with the grip ring, the parallel member is integrally formed with the left member and the right member. It is also possible to form.

In addition, in the drawings of the present specification, the plurality of pressing portions constituting the grip ring are illustrated as being formed in the same shape, but, alternatively, the shapes of the plurality of pressing portions may be formed differently.
