- the socket-type pipe interface in which the anchoring structure is a stopper (or a similar component) is favored by the majority of users because of convenient construction and being easy to fall off.
- the interface generally includes a socket and a socket, and a protrusion is arranged on the socket. After the socket is inserted into the socket, a stopper is inserted from the stopper mounting hole, and the socket is anchored in the socket through the stopper to prevent the socket and the socket. The connection is disconnected.
- the stopper is an important guarantee for the reliability of the interface connection. Once the stopper is detached, the interface connection performance is impaired, and the socket may be detached from the socket. Therefore, how to ensure that the stopper does not fall off during the installation and use of the interface is an important technical problem that is of concern to those skilled in the art.

- the 116 is placed behind the annular wall 113 and the next block 115 is then mounted.
- the stops 115 are tightened to the outer tube wall of the socket 110 by a steel band 112 or other locking material.
- the projection 117 on the socket 110 acts on the right end surface of the stopper 115, and the anti-slip projection 116 on the stopper 115 acts on the axial direction of the annular wall 113 of the socket 111.
- the bevel 118 prevents the socket 110 from slipping off.
- the step of fixing the stopper is cumbersome, and it is necessary to bundle the steel strip after the stopper is installed, thereby increasing the installation step; at the same time, the socket is moved in the axial direction due to the external force, and the multiple axial movement is likely to cause
- the steel strip of the fixed stop is loose or even broken; and other locking materials such as steel strip are directly in contact with the external environment, which is easily affected by environmental impact corrosion, loses the locking function, and causes the stopper to fall off.
- the cost of using the steel strip is relatively low. high.
- FIG. 2a-2c Another common socketed pipe joint is disclosed in the patent document US Pat. No. 4,685,708 A.
- the stop 30' is arcuate and the stop 30' is connected by a pin 34' to form an annular retaining ring 24'.
- Plates 36' and 38' of adjustment means 26' are respectively provided on the opposite ends of one end 30c' of one of the stops 30' and the other end 30', which are assembled by the connecting plates 36' and 38'.
- the retaining ring 24' is placed in the stop block 22' and the inner diameter of the retaining ring 24' is greater than the weld ring on the socket 10'
- the outer diameter of 28' is such that the weld ring 28' smoothly passes over the retaining ring 24'.
- the distance between the two end portions 30c' and 30d' is adjusted by the adjusting device 26' to fix the retaining ring 24' to the outer surface of the socket 10' to prevent the socket 10' from bearing.
- the mouth 12' falls off.
- the socket type pipe joint does not use the steel strip of the fixed stop 30', but the block 30' needs to be connected by the pin 34', and the adjusting device 26' is used to fix the retaining ring 24', and the adjusting device 26' Not only need to be connected with the stopper 30', but also the bolt 42', the base 40', 44' and the nut 46' are provided.
- the adjusting device 26' of the fixed retaining ring is in the external environment, and is also susceptible to environmental corrosion, which causes the interface to lose its self-locking function.

Therefore, it is not necessary to open a stopper mounting groove on the annular wall extending radially inward of the end portion of the socket, and the annular wall is A complete wall enhances the strength of the interface connection.
- the diameter of the retaining ring is smaller than that of the stop block. Therefore, when the retaining ring is placed in the block bin, the retaining ring falls on the lower part of the block bin, around the block bin, without the elastic support body being installed. Separating, thus losing the force that gathers the stops that make up the retaining ring, the block that constitutes the retaining ring is easy to fall off or the center of the retaining ring is off-center, which makes the socket difficult to install, and even the socket cannot be installed into the socket.
