Because set up metal reinforcing belt ring 3 on the outer peripheral face of bellmouth portion 1, this metal reinforcing belt ring 3 can cramp bellmouth portion 1 and socket portion 2, make the joint strength between bellmouth portion 1 and socket portion 2 bigger, when receiving external pressure, more be difficult to separate and fracture, and, because be provided with integrative reinforcing part 4 that bends and form on the metal reinforcing belt ring 3, when socket portion 2 inserts bellmouth portion 1, this reinforcing part 4 can take place certain elastic deformation, thereby provide certain space for the bulging deformation of bellmouth portion 1, effectively avoid because the phenomenon that bellmouth portion 2 can't insert bellmouth portion 1 because the effect of cramping of metal reinforcing belt ring 3 is too big.

Wherein, the socket part 1 and the socket part 2 are respectively located at the end parts of the two pipelines, at least one annular protrusion 201 is arranged on the outer peripheral surface of the socket part 2, the inner wall of the socket part 1 is provided with a corresponding annular groove 101, and the annular protrusion 201 is embedded into the corresponding annular groove 101 to realize the self-locking between the socket part 1 and the socket part 2 (as shown in fig. 1 and 2).

In some embodiments, as shown in fig. 1 and 2, the socket portion 1 is provided at a root thereof with a sealing ring positioning groove 102, a sealing ring 103 is disposed in the sealing ring positioning groove 102, and a protrusion 202 is disposed on the socket portion 2 corresponding to the sealing ring positioning groove 102, wherein the protrusion 202 is used for pressing the sealing ring 103 in the sealing ring positioning groove 102. Thereby, sealing between the socket part 1 and the socket part 2 can be realized, and liquid leakage in the pipeline is avoided.

In some embodiments, see fig. 1 and 2, the inner wall of the end of the socket 1 (i.e. the end away from the root, i.e. the right end in fig. 1) is provided with a frustoconical guide surface 104; therefore, when the socket part 2 is inserted into the socket part 1, accurate alignment is not needed, and the operation is more convenient.

Preferably, an annular positioning groove 105 for positioning the metal reinforcement band 3 is provided on the outer peripheral surface of the socket portion 1, and the metal reinforcement band 3 is disposed in the annular positioning groove 105. By the positioning function of the annular positioning groove 105, the metal reinforcement ring 3 can be prevented from falling off, and the axial position of the metal reinforcement ring 3 is ensured to be fixed.

Wherein, the quantity of metal reinforcing belt ring 3 can set up according to actual need, can be one or more, and when metal reinforcing belt ring 3 was provided with a plurality ofly, a plurality of metal reinforcing belt ring 3 intervals set up. For example, in fig. 1 and 2, the metal reinforcement belt loop 3 is provided with one, but not limited thereto.

The number of the reinforcement parts 4 in each metal reinforcement belt loop 3 can be set according to actual needs, and can be one or more. When a plurality of reinforcements 4 are provided in each metal reinforcement belt loop 3, these reinforcements 4 are preferably evenly distributed in the circumferential direction. For example, in fig. 3, each metal reinforcement belt loop 3 is provided with two reinforcements 4, and these reinforcements 4 are preferably evenly distributed in the circumferential direction, but not limited thereto.

Preferably, when a plurality of metal reinforcement ring loops 3 are provided, the reinforcement parts 4 between adjacent metal reinforcement ring loops 3 are staggered with each other, so that when the spigot part 2 is inserted into the socket part 1, the socket part 1 can be more uniformly expanded and deformed, and the smoothness of the insertion process is ensured.

Wherein, the reinforcing part 4 can be convex inwards or convex outwards; for example, the reinforcing portion 4 in fig. 3-8 is an outwardly convex structure.

Wherein, the concrete shape of the reinforcing part 4 can be set according to actual needs.

For example, in some embodiments, see fig. 4, the reinforcement 4 is a ladder-type reinforcement comprising a first flat plate 401 and first side plates 402 symmetrically disposed on either side of the first flat plate 401, the first side plates 402 being at an angle greater than 90 ° to the first flat plate 401.

For example, in some embodiments, see fig. 5, the reinforcement portion 4 is a rectangular reinforcement portion comprising a second plate 403 and second side plates 404 symmetrically disposed on both sides of the second plate 403, the second side plates 404 being at an angle of 90 ° with respect to the second plate 403.

For example, in some embodiments, see fig. 6, the reinforcement 4 is an arc-type reinforcement.

For example, in some embodiments, see fig. 7, the reinforcement 4 is an m-type reinforcement.

In some preferred embodiments, the metal reinforcement belt loops 3 have a thickness of 0.5mm to 0.7mm and a width of 2.8cm to 3.2 cm; the height of the reinforcement 4 is 1mm-1.5mm (the height of the reinforcement 4 refers to the difference in radial distance between the point where the radial distance between the reinforcement 4 and the center of the metal reinforcement belt loop 3 is the largest and the point where the radial distance is the smallest). Within the size range, the capacity of bearing external load at the joint of the socket part 1 and the socket part 2 can be effectively improved, so that the joint is not easy to separate and break, and the smoothness of inserting the socket part 2 into the socket part 1 is ensured.

Preferably, the distance between the metal reinforcement belt loops 3 closest to the end of the socket 1 and the end of the socket 1 is 4cm-5 cm. In the process of inserting the spigot portion 2 into the socket portion 1, due to the extrusion effect of the inserted portion, the outer diameter of the root position of the spigot portion 2 becomes large, so that the end of the socket portion 1 is required to have better deformation performance, otherwise, the root of the spigot portion 2 is difficult to insert into the socket portion 1, so that the insertion is not in place, if the metal reinforcing band ring 3 is arranged too close to the end of the socket portion 1, the deformation performance of the end of the socket portion 1 is poor, so that the socket portion 2 is difficult to insert in place, and if the metal reinforcing band ring 3 is arranged too far away from the end of the socket portion 1, when the connecting part bears external load, the metal reinforcing band ring 3 and the end of the socket portion 1 are easy to break at the position between the metal reinforcing band ring 3 and the end of the socket portion 1. Within this size range, the problem that the socket portion 2 is difficult to insert in place due to an excessively small distance and the improvement effect of the external load bearing capability of the joint between the socket portion 1 and the socket portion 2 is poor due to an excessively large distance can be avoided.
