Meanwhile, the pipe crimping fastener according to an embodiment of the present invention includes a fixed block 6 and a floating block 8.

The fixed compression block 6 and the fluid pressure compression block 8 are arranged in the vicinity of the joint P 1 of the pipe P in direct connection with the compression and tilting operation of the connecting pawl 2 and the pressure support 4, So that it can be pressed and pressed.

The fixed compression block 6 is formed in a state of hingingly connecting the connection support portion 2 and the pressure support portion 4. [

The fixed press block 6 has a pressing portion C1, and a plurality of the pressing blocks C1 are constituted by one set.

In particular, the fixed press block 6 is set so that a fixed pressing operation can be performed in a fixed state

2 to 3, the fixed compression block 6 is hinge-coupled between both ends of the connection support portion 2 and one end of the pressure support 4, for example, Two of the hinge pins H are connected to each other, and the hinge pins H can be fixedly installed in a state in which one of the hinge pins H is disposed inside the connection support unit 2, which are disposed in a superimposed manner.

The fluid-type compression block 8 is disposed so as to be able to press the periphery of the joint P1 of the tube P together with the fixed compression blocks 6.

The fluid pressure compression block 8 is provided with a pressing portion C2 and is constituted by two pairs so as to correspond to the two pressure supports 4. [

That is, the fluid type compression block 8 can be respectively arranged in a state corresponding to the guide portion A of the two pressure supports 4 as shown in Figs. 2 and 4, for example.

The pressing portion C2 of the fluid type pressing block 8 can be pressed and fastened around the joining portion P1 of the tube P by a conventional method like the pressing portion C1 of the fixed pressing block 6 4 as shown in FIG.

Particularly, the fluid type compression block 8 is installed in a state in which the fluid pressure operation can be performed while sliding on the pressure support 4 side during the compression and tightening operation.

For example, as shown in FIG. 4, a guide plate D may be provided on the pressure support 4 so as to hold the fluid-type compression block 8 so that the fluid-type compression block 8 can slide.

5, the fluid presser block 8 may be moved in a state of being slid along the joint P1 of the tubular body P, so that the flow pushing operation can be performed.

In addition, the fluid pressure compression block 8 can be provided in a state in which the sliding operation can be elastically restricted.

For example, as shown in FIG. 2, the elastic member D1 may be installed inside the guide plate D so as to exert an elastic force in a state of pushing the fluid type compression block 8 in one direction.

6, in the state in which no external force acts, the two fluid-type compression blocks 8 are separated from the adjacent fixed block 6 in the direction So that the elastic force can be applied.

7, when the two pressure supports 4 are compressed and tightened, the one end of the fluid pressure compression block 8 comes into contact with each other, and the elastic force is elastically slid toward the other side And is set to a state capable of operating.

Then, the fluid type compression block 8 can be elastically pressed in conjunction with the pressing and tightening operation of the pressure support 4.

According to the structure of the engaging portion 10 as described above, when the pressure support member 4 and the connection support member 2 are disposed in a state of wrapping around the joint P1 of the tube P, It is possible to prevent the wrapped state from being released to the non-normal state as the distance of the earth 4 is increased.

Then, as shown in FIG. 8, since the crimping connector T for the clamping type can be easily set so as to correspond to the two pressure supports 4, further improved ease of operation can be ensured.

Next, a preferred working example for the compression bonding operation of the joining part P1 of the pipe body P using the piping pressing fastener of the present invention will be described.

9, the pressure support member 4 and the connection support member 2 are disposed in a state of wrapping around the joint P1 of the tubular body P and then the operation portion B of the pressure support portion 4 (T) is set on the side of the press-fitting terminal (T).

Then, when the compression bonding end (T) is operated in the tightening direction by a separate driving source (not shown), the two pressure supports (4) are operated in the direction in which the interval is narrowed.

10, the stationary compression block 6 and the fluid pressure compression block 8 are connected to each other by the tightening operation of the pressure support 4 and the connection support 2, ) In the direction of reducing the peripheral diameter.

By this operation, the joint P1 of the tubular body P can be pushed to the pressing portions C1, C2 of the fixed-type pressing block 6 and the fluid-type pressing block 8, and can be connected by the press-fitting method.

Particularly, in the press-clamping operation as described above, the fixed-type compression block 6 and the floating-type compression block 8 are operated in different pressing states.

9 and 10, the fixed compression block 6 is slid along the joint portion P1 of the tubular body P on the side of the connection support portion 2 and the pressure support portion 4 So that it is pushed in a fixed state.

On the other hand, when the fluid pressure compression block 8 is operated in a state where the distance between the two pressure supports 4 is narrowed, as shown in FIGS. 9 and 10, Is pushed in a state in which it is slid in the same direction as in the drawing along the periphery of the platen P1.

The slide operation of the fluid type compression block 8 not only serves to guide the movement direction so that the pressure can be smoothly compressed when the pressure supports 4 are operated in the narrowed state, 8, the fixed compression block 6 and the fluid pressure compression block 8 are in a state of a substantially regular circle so as to correspond to the circumference of the joint P 1 of the pipe P as shown in FIG. 10, As shown in Fig.

Therefore, when pressing around the joint P1 of the tubular body P, only the fluid type compression block 8 for guiding the compression operation flows, and the fixed type compression block 6 can be prevented from flowing The circumferential surface of the joint P 1 of the tube P can be easily broken or deformed into a non-normal state by the flow of the compression blocks 6 and 8, .

Therefore, the present invention can provide a push structure that can suppress the breakage or deformation of the circumferential surface of the joining part (P1) of the tubular body (P) as much as possible, thereby ensuring further improved work quality and stability of work.
