圧具の当接する傾斜面が直線状であり、がっ比較的急な
角度(通常は15°前後)に設定される。In recent years, as a detachment prevention fitting for fluid pipe joints, an object with an inclined surface on the upper part has been incorporated into the press ring, and the object can be pressed from the outside in the direction of the pipe with a bolt or other pressing tool, and the object can be placed at the bottom of the object. A type without cutting the cutting edge into the surface of the insertion part
9213, Japanese Utility Model Publication No. 55-3i338, etc.) In these conventional devices, the inclined surface that the actual suppressor comes into contact with is straight, but at a relatively steep angle. (Usually set at around 15 degrees).

欠点がある。This is an angle obtained from a relationship that provides a force to prevent digging when the insertion part separates from the receptacle, and no consideration is given to the initial digging force when setting the entity. Therefore, in the case of an object with a steep slope, the bottom of the object and the surface of the socket will easily slide when installing the detachment prevention fitting, and the object will not fit fully into the socket. It cannot be locked. For this reason, when the receptacle part is removed from the receptacle part, the bottom of the wedge body and the surface of the receptacle part slide, resulting in a drawback that a predetermined detachment preventing force cannot be exerted.

Consisting of a gently sloped surface 32 connected to the steeply sloped surface 31 and the rear end surface 12 and has an angle β (usually around 5 degrees). aia is a groove formed in the steeply sloped surface 31, and 32aVi is a groove formed in the gently sloped surface 32. This is the groove that was created.

。It is a five-ring-shaped push ring, which is fitted into the socket 6 at the joint of the fluid pipe and engaged with the socket 7 by appropriate known means (for example, a fastener made of a bolt or nut). . The push ring 5 is in contact with the end face of the receiving socket 7 in this example, but in the case of a mechanical joint, an arm portion that compresses and suppresses the backing loaded in the receiving port protrudes from the pushing ring. It is provided. A wedge housing portion 51 is formed in a bulging shape over a predetermined location in the circumferential direction of the press ring 5, and a screw hole 5ia into which the bolt 4 is screwed passes through the ceiling wall of the housing portion 51. It is screwed. Screw hole 5
1au The above-mentioned inclined posture of the bolt 4 is maintained by tilting the hole axis toward the tube axis at an appropriate angle γ from the right angle to the tube axis.

上述の抑圧力の伝達は均等に行われることになる。When installing this detachment prevention fitting, the tip 41 of the bolt 4 is brought into contact with the gently sloped surface 32 at the rear of the wedge piece 1, and when the bolt 4 is further rotated and tightened, a strong pressure is applied to the surface of the wedge piece 1 insertion opening 6. will be done. At this time, the pressing force of the bolt 4 is
If the blade 2 is formed with a gentle slope, the force will be transmitted vertically (in other words, the component force in the horizontal or tube axis direction will be small), and if the cutting edge 22 corresponding to the slope 32 is formed narrowly, As the contact area becomes smaller and the pressing force is further concentrated, the cutting edge 22 of the wedge piece 1 will forcefully bite into the surface of the insertion opening 60. As a result, engagement of the wedge piece 1 with the surface of the insertion portion 6 during installation becomes reliable. Note that when forming the groove 32a with a circular cross section on the inclined surface 32 of the wedge piece 1, the tip 41 of the bolt 4 makes a line contact with the groove 32a,
The above-mentioned suppression force will be transmitted evenly.

程の距離にはならず、小さな距離で止まるものである。Direction in which the insertion port 6 separates from the socket B7 (direction A in Figure 2)
When a pull-out force is applied to the socket and the socket 6 moves from the socket 7, the wedge piece 1 is biting into the surface of the socket 6, so the socket 6
◇ However, since the initial contact movement between the bolt salt and the wedge body 1 is performed on the gently sloped surface 32, when this pulling force is small, the movement of the insertion part is caused by the taper action of the gently sloped surface 32. Sufficiently prevented. When the pulling force becomes large, the gently inclined surface 32 of the tip 41H of the bolt 4
It slides over the top and reaches the steeply sloped surface 31 at the front of the wedge piece 1, causing a strong taper action on the surface 31. Since the bolt 4 is restrained by the push ring 4, the steeply inclined surface 31
The force generated is transmitted downward to the wedge piece 1 (inward of the pipe diameter),
In addition, if the cutting edge 21 at the front of the wedge piece 1 is formed wide, it can withstand an even larger load, and the insertion part 6 is strongly tightened by the wedge piece 1 and the detachment prevention metal fitting, and It will exert an ejection-preventing power. Incidentally, when the groove 31' having a circular cross section is formed on the inclined surface 31 of the wedge piece 1, the groove 31a and the tip end 41 of the bolt 4 come into line contact, so that the force is transmitted even more smoothly. As the wedge piece 1 moves as the insertion port 6 is pulled out, it comes into contact with the rear part of the bolt tip 41 on the gently sloped surface 32 and the front part of the bolt tip 41 on the steeply sloped surface 31. Therefore, the distance is not as great as it appears, but it stops at a small distance.

。That is, although the wedge body is a piece-shaped wedge piece in the first embodiment, it may be a ring-shaped wedge body (cut ring) that is fitted around the tube of the insertion port. In this case, the wedge housing portion 51 of the press ring 5
Needless to say, it becomes longer in the circumferential direction, and that pressing tools are provided at various places in the circumferential direction. In addition, the pressing tool is
In the embodiment, a bolt is used, but other means such as a protrusion protruding into the wedge housing portion 51 of the press ring 5 may be used.

に便利となる。Still another embodiment of the present invention is shown in FIGS. 5 and 6. The feature of the structure of this embodiment is that the tip of the bolt 4 is a truncated conical bolt tip 4f, and the groove provided in the wedge 1 is a dovetail groove 3b that loosely engages the bolt tip 4f. That's true. Other configurations are similar to the first embodiment. With this configuration, both the bolt 4 and the wedge body 1 are always in an engaged relationship, and the relative position of both can be easily maintained during installation, and the parts do not dissipate during transportation, making it convenient for parts management.
