Description

DETAILED DESCRIPTION OF THE INVENTION Misfire (7) relates to a device for preventing joint pipes such as gas pipes and water pipes from coming off. A nine-piece stopper, which is equipped with a protrusion that bites into the socket, is inserted into the annular deep retainer connected to the socket pipe, and the retaining member 11 is placed on the outer side of the pipe. A suppression joint is provided to press the
The locking member marked OU is pressed to the (''* side) on the outer circumferential curved part of the locking member and the inner circumferential surface part of the recording holding part, respectively, as the pushing force of the locking member marked I is worn out. Dislodgement of the tangential 1st class pipe with the cam part held in place 11:me As shown in the figure, even if the push bolt as a suppressor is pressed in a posture perpendicular to the cam part on the locking member side (1) obliquely (m), and the push bolt is pressed +f vc y,

+l=.

In jointed pipes, it is desirable to have flexibility at the pipe joint so that the jointed pipe can tolerate shrinkage due to temperature changes, etc. to a large extent. Transfer of the members + by the King of Porto 1) 11
There is a disadvantage in that it cannot be used for joint pipes that expand and contract over a large range due to the fact that it is difficult to use, so there is a need for improvement.

The misfire (7) was made in view of the above-mentioned situation, and its purpose was to include a part of the first part (the function to make the first part of the orchestra and the cam part). te person +t-i"tl's
The object of the present invention is to provide a device for disassembling a jointed pipe that can create a PTf valley in a large range over the entire width of the jointed pipe, while having the function of pressing the entire surface of the jointed pipe.

The special feature of the joining pipe detachment prevention device a according to the present invention is that the pressing tool is a shaped portion that prevents the locking member described in 111 from moving to the insertion/extraction output time. In addition, the cam portion is provided so as to have a suppressing action, and the cam portion starts the pushing action after the engaging member has moved within a certain range in the insertion tube extraction direction with respect to the holder mQ. The above-mentioned locking member and the above-mentioned time keeping body are provided in a non-contact state with respect to the +jtl cam portion so that they can be assembled in any size, and the functions and effects thereof are as follows.

That is, while pressing the cam part with the pressing tool, the body part is allowed to move in the direction of extracting the extended bone [7, and the suppressing action of the cam part is suppressed by the latching part rsI6. The operation is started after the holder moves within a certain range in the direction of extraction of the inlet tube.

Therefore, by attaching the locking member so that it bites into the insertion tube with the suppressor, and by operating the cam part If, as the locking member moves in the direction of extraction before the push-button, the locking member 1 It has the flexibility to prevent the movement of the part and at the same time to ensure that it bites into the insertion tube, and to measure the distance in the longitudinal direction of the pipe over a large range while allowing each part to follow the specified path. Therefore, it is extremely suitable for connecting pipes that shrink due to temperature changes and the like.

As shown in Figures 1 and 2, the insertion tube (1) is purple and is freely inserted into the large diameter portion of one end of the socket tube (2), and a rubber gasket (3) is attached to both tubes t1) and +2+. Attach the joint to the outside of the tube (1), and then insert it into the outside of the tube (1)! A protrusion (a) that bites into if t & i is provided on the inner peripheral surface side, and
Circumferential direction -+;! A C-shaped retaining member (4) with a divided fi position is provided so that the details can be freely deformed, and the retaining part (4) is crimped to the outer circumference of the insert (-1 information; tl). A pair of left-row presses as push IE tools 5] is provided with a push-down part so that both ends of A(4) are brought closer together, and , (thread 1F member (4)
Part 1 (4) An annular holder with inner bottom (6) gold, connected to the socket tube (2) described in 11. The structure is such that the joint tube will not come off in all cases.

Next, the valley will be explained in detail.

The breather 1 of the socket pipe (2) is also attached to the Nolanji i41 (2a,

It has a VCC configuration so that the rubber gasket (3) can be pressed to hold the lightning.

When the pair of press bolts (5) are screwed into the outer circumferential expansion 114 (6c) of the holding body (6), a tongue-shaped press is formed which is pressed by the pair of press bolts (5). Part (4a

, is installed in the non-contacting part of the VC1 pipe, thereby providing flexibility in the contact part of the VC1 pipe so that expansion and contraction of the joint pipe due to temperature changes etc. can be tolerated within a reasonable range. (maybe, move the presser tube (1) toward the extraction direction.)
Along with j, the wedging action of the cam part +81 and iTl ensures that the interlocking part toe (4) bites into the one-car 10 pipe (1) to ensure that both the pipes t1+ and (21) are prevented from coming off. It is composed of:

To form the cam portions +81 and t'lrl, (the thread 1 is provided with multiple cam protrusions such as the member 11111 cam portion ts+, at intervals of 1 ml in the circumferential direction), and The cam as +T+, the bulge part (6C)
The entire circumference of the opening circuit, except for the opening circuit, is shaped like I.

Next, another embodiment will be explained.

In addition to providing the pair of push bolts (5) mentioned above, various modifications can be made to the press. For example, Fig. 6 and the bulge (
6C) is provided with a freely abutting ring-shaped portion (9a) on the other suppressed portion (4a), and the bolt is pushed through the bulged portion (6c). Hole (1n)
