Description

The pipe separator

The present invention relates to a pipe separator for separating pipes coupled with one-touch fittings inside a fitting, and more particularly, to a pipe separator which is connected to a fitting and can be easily moved with a small force.

In general, pipe joints for jointing pipes used in water pipes and the like have various shapes and various materials. In order to connect the piping, most of the joints are provided with a separate cap or the like on the body of the joint so that the piping is connected by screwing the cap.

In the case of such a joint, there is a problem in that the construction is difficult because a separate connecting tool or the like used for assembling must be used. Therefore, it is urgently required to develop a joint capable of piping without a separate tool, and a registration application 10-0984839 (name of the invention: pipe connection) was provided. Such prior art includes a stop member formed with different curvature centers on the outer circumferential surface and the inner circumferential surface, so that the stop member can smoothly move between the pipe and the body along the inclined portion, maximizing the function of the wedge, I can fix it. Further, since the second elastic member is made of the wave spring so as to elastically support the stop member in the axial direction (or in the pipe advancing direction), the shape change due to the external force is small and is not affected by the rotating pipe at all, Even when the connected pipe was twisted and shaken, the change of the position of the stopping member was minimized and the pipe was prevented from falling off.

In this way, a pipe separating tool for applying an external force to the stopping member in the direction of entering the pipe coupled to the inside of the body is provided so that the pipe can be easily separated from the body through the pipe separating tool.

However, the pipe separating tool used in the prior art can bend the ordinary wire to make it easy to manufacture. However, when the diameter of the pipe is relatively large, it is difficult to transmit the force.

In order to solve the problem of the conventional pipe separating tool, the pipe separating tool 100 is provided with first and second fasteners 110 ) 120; The first and second fasteners 110 and 120 are formed to correspond to the outer circumferences of the first and second fasteners 110 and 120. The first and second fasteners 110 and 120 are coupled to the inside of the hollow metal fitting 200, Thereby separating the pipe 300 coupled with the one-touch type from the fitting 200.

At this time, the fitting 200 is sequentially inserted into the both sides of the wedge 250 coupled with the ring 210, the watertight packing 220, the washer 230, the elastic member 240, and the elastic ring 250a, The pipe 300 is bound in a one-touch type.

2, the first and second fasteners 110 and 110, which constitute the pipe separating tool 100, are provided in the inner diameter of the fitting 200 in order to separate the pipe 300 bound in the one- The wedge 250 is inserted into the elastic member 240 in a state in which the wedge 250 is pressed inward while holding the wedge 130 of the outer periphery of the first and second fasteners 110 and 120, The clamping force of the pipe 300 coupled to the inside of the wedge 250 is released so that the pipe 300 is easily separated from the inside of the wedge 250 of the fitting 200. [

However, such a conventional pipe separating tool not only has a difference in user satisfaction depending on the skill of a user and a difference in gripping force, but also increases the outer diameter of the pipe bound to the fitting, Lt; / RTI >

At this time, a pair of coupling nuts 64 are fastened to the adjustment bolts 63 to maintain the height of the locking rotation levers 61 and 62 whose height is adjusted.

The hinge member 70 includes first and second hinge pieces 71 and 72 provided between the outer circumferential surfaces of one side of the first and second binding rings 51 and 52, A vertical hinge pin 74 for rotatably connecting the first and second hinge pieces 71 and 72 between the first and second hinge pieces 71 and 72; And an elastic spring 76 which is wound around the outer peripheral surface of the vertical hinge pin 74 to elastically support the rotation of the binding rings 51 and 52.

The binding member 80 includes a fixing body 82 fixed to the other outer peripheral surface of the first binding ring 51; A rotator 84 having one side rotatably coupled to the fixture 82; A pivotal ring 86 pivotably coupled to the pivotal body 84; And a retaining ring 88 which is fixed to the other outer peripheral surface of the second binding ring 52 and to which the rotating ring 86 is caught.

The state of use of the pipe separator according to the present invention will be schematically described.

3, the pipe 20 is coupled to the joint 10 on both sides of which the pipe is expanded. When the pipe 11 and the watertight packing 12 are fitted into the joint 10, The wedge 15 combined with the elastic member 13, the elastic member 14 and the elastic ring 15a are sequentially inserted.

The wedge 15 coupled with the ring 11, the watertight packing 12, the washer 13, the elastic member 14 and the elastic ring 15a is inserted into the fitting 10 in which the wedge 15 is sequentially inserted, The pipe 20 is easily coupled by the wedge 15 coupled with the elastic ring 15a to prevent the pipe 20 from coming off.

In order to separate the pipe 20 bound in the fitting 10 as described above, the pipe separator 30 provided as shown in FIGS. 4 through 7 is coupled to the inside of the fitting 10 to easily separate the pipe 20 with less force.

8A and 8B, the movement separator 40 of the pipe separator 30 is rotated around the hinge 40 in the direction of the arrow to maintain the circular shape, The inner circumferential surface of the inner insertion rings 41 and 42 of the inner joint ring 40 is inserted into the fitting 10 (see FIG. 10A).

9A and 9B, the binding rings 51 and 52 constituting the separating and grasping body 50 are rotated in the direction of the arrow with the hinge member 70 to be aligned with the outer peripheral surface of the fitting 10 The pivotal ring 86 constituting the binding member 80 is hooked on the pivotal ring 88 and then the pivotal member 84 is completely pivoted outward from the fixed body 82 to move the coupling rings 51, Thereby stably binding the inner circumferential surface of the fitting 10 to the outer circumferential surface.

10B, the latching pivoting levers 61 and 62 of the separation grill body 50 are rotated about the pivoting pin 55 in the direction of the arrow so that the latching pivoting levers 61 and 62 The hooks 67 are hooked on the locking projections 60 protruding from the outer closing rings 43 and 44 and then pushed into the fixing brackets 53 and 54 by the pivoting lever 55, (56) and (57) sequentially inward.

As the pivoting levers 56 and 57 are pivoted inward about the pivot pins 55 and 58 to pivot into the fixing brackets 53 and 54, And the adjusting bolts 63 of the latching pivoting levers 61 and 62 fastened with the adjusting bolts 63 to the screw holes 59a of the pivoting shafts 59 are moved inward to be coupled.

The wedge 15 is pushed by the elastic force of the elastic member 14 as the inner insertion rings 41 and 42 of the movable separator 40 move and the end of the wedge 15 presses the wedge 15, So that the tightening force is released from the pipe 20 inside the wedge 15. [ When the pipe 20 is separated in the B direction in this state, the pipe 20 is easily separated from the inside of the fitting 10.

When the pipe 20 is completely separated from the pipe 20, the pivoting levers 56 and 57 are pivoted around the pivoting pins 55 and 60, The inner insertion rings 41 and 42 of the movable separation member 40 are moved outwardly by the restoring force of the elastic member 14 And the wedge 15 returns to its original position.

The outer peripheral surface of the inner insertion rings 41 and 42 of the movable separator 40 is separated from the inside of the fitting 10 and then the rotary body 84 constituting the binding member 80 is fixed to the fixing body 82. [ When the coupling rings 51 and 52 are separated from the outer peripheral surface of the fitting 10 after the turning ring 86 is disengaged from the coupling ring 88, ).
