TECHNICAL FIELD

[0001] The present application relates to the field of pipe materials, in particular to a double socket pipe connecting structure. BACKGROUND

[0002] Pipe materials are necessary materials for building engineering. In order to facilitate transportation, the length of each pipe material cannot be too long, and needs to be connected on site. In the related art, the pipe material is usually directly connected by socket and socket, which does not have a anti-disengagement structure and is easy to disengage. Moreover, the pipe material is usually a circular structure, which is easy to roll and difficult to transport and install. SUMMARY

[0003] Therefore, the present application provides a double socket pipe connecting structure, which has anti-disengagement capability and good pipe stability.

[0004] In order to achieve the above purpose, the present application realizes the following technical scheme:

[0005] A double socket pipe connecting structure, characterized in that: it comprises at least two pipe materials and a connecting pipe piece connected between the two pipe materials, the pipe material comprises a pipe body and two socket ends fixedly arranged at both ends of the pipe body, the connecting pipe piece comprises two oppositely fixed socket ends, the socket ends are used for receiving the socket ends, the socket ends are fixedly provided with anti-disengagement parts, the socket ends are provided with anti-disengagement grooves, and the anti-disengagement parts are used for entering the anti-disengagement grooves to form clamping joints with the anti-disengagement grooves.

[0006] The double socket pipe connecting structure of the present application has two socket ends, and the anti-disengagement parts are arranged on the socket ends. Moreover, the connecting pipe piece has two socket ends, and the anti-disengagement grooves are arranged in the socket ends. After the pipe materials are connected, a clamping joint structure is formed, which has anti-disengagement capability. Moreover, the pipe material is a double socket structure, and the connecting pipe piece is a double socket structure. When installed, it is not necessary to distinguish which end of the pipe material is a socket or a socket. Direct connection can be achieved, and on-site installation is more convenient.

[0007] In some embodiments, the pipe body is a corrugated pipe, the outer shape radial section of the wave crest of the pipe body is a regular octagon, the corners of the regular octagon are arc transitions, the socket ends each comprise a clamping section, the outer shape radial section of the clamping section is a regular quadrilateral, the corners of the regular quadrilateral are arc transitions, the planes where the four edges of the clamping section are located are coincident with or parallel to the planes where the four edges of the wave crest of the pipe body are spaced apart, the four corners of the clamping section are protruded from the other four edges of the wave crest of the pipe body, and the anti-disengagement grooves are arranged on the inner walls of the four corners of the clamping section.

[0008] The pipe body of the pipe is an octagon, and the clamping section of the socket end is a quadrilateral, so that the pipe has four surfaces as placement planes, facilitating transportation and installation.

[0009] In some embodiments, the socket end further comprises an inlet section integrally connected with the clamping section and located close to the port, the anti-disengagement part is an anti-disengagement wave integrally formed on the spigot end, the clamping section is provided with a slit at each of the four corners, the slit communicates the anti-disengagement groove and the outer wall of the clamping section in the radial direction and extends to the port of the inlet section in the axial direction, so that the inlet section and the clamping section can be radially expanded when the spigot end is inserted into the socket end, so that the anti-disengagement wave enters the anti-disengagement groove and is clamped therein. The socket end can automatically expand when the spigot end is inserted, facilitating the anti-disengagement wave to enter the corresponding position and improving the installation efficiency. Moreover, the structure does not require a separate accessory, and the anti-disengagement wave is directly formed on the spigot end, so that the pipe has good mechanical properties.

[0010] In some embodiments, the anti-disengagement wave is a tapered wave, the outer shape of the tapered wave close to the port side of the spigot end is smaller, and the outer shape of the tapered wave away from the port side of the spigot end is larger. The tapered wave facilitates the insertion of the spigot end.

[0011] In some embodiments, the socket end further comprises a sealing section integrally connected with the clamping section for cooperating with a sealing ring to seal.

[0012] In some embodiments, the double-spigot pipe connection structure further comprises a sealing ring fixedly arranged on each spigot end, the spigot end is provided with a sealing mounting wave crest or a sealing mounting wave valley for clamping the sealing ring, and the connecting pipe fitting further comprises a limiting small wave arranged at the connection between the two socket ends and protruding into the pipe, and one end of the two sealing rings abuts against the two side portions of the limiting small wave, respectively. In this structure, two separate sealing rings are required in the connecting pipe fitting for installation. The sealing ring needs to be installed on the spigot end first, and then the two spigot ends are connected. In this structure, the sealing ring is relatively simple to install.

[0013] In some embodiments, the connecting pipe further comprises a clamping wave provided at the joint of the two socket ends and protruding into the pipe, the double socket pipe connecting structure further comprises a sealing ring installed in the clamping wave, and an inner ring of the sealing ring is integrally provided with a protruding ring protruding inward, the two socket ends abut against the axial two sides of the sealing ring, and the protruding ring is located at the joint of the two socket ends and extends into the pipe of the socket end. The inner diameter of the protruding ring is smaller than the inner diameter of the socket end. In this structure, only one sealing ring is needed to be installed in one connecting pipe. Moreover, the sealing ring is directly installed in the connecting pipe, and the sealing ring is further provided with the protruding ring which extends into the pipe of the socket end. Therefore, when the cable is arranged, the cable usually only contacts the protruding ring and does not contact the port position of the socket end, and because the protruding ring is relatively soft, the risk of cable scratch can be reduced.

[0014] In some embodiments, the socket end is further integrally provided with a sealing conical wave for pressing the sealing ring, the sealing conical wave has a smaller outer shape near the port side of the socket end and a larger outer shape away from the port side of the socket end. The sealing conical wave can press and extrude the sealing ring in a conical surface, so that the compression force is larger and the sealing performance is good. In order to further improve the sealing performance, the sealing section can also be provided in a conical structure.

[0015] In some embodiments, the anti-extraction part is an anti-extraction piece which is separately installed on the socket end, and the anti-extraction piece comprises a folding blade with elasticity. When the socket end is inserted into the socket end of another pipe, the folding blade enters the anti-extraction groove in a radial folding and shrinking manner, and then the folding blade is automatically reset into the anti-extraction groove to form a clamping connection. The folding blade can be pressed and folded, so that when the pipe is inserted, the folding blade can be pushed to the anti-extraction groove to form a clamping connection, thereby reducing the installation difficulty of the pipe.

[0016] In some embodiments, the socket end is provided with an anti-extraction installation groove for installing the anti-extraction piece, and the anti-extraction piece is clamped in the anti-extraction installation groove. The anti-extraction installation groove is used for clamping the anti-extraction piece. Preferably, the anti-extraction installation groove is provided in a circular shape, the anti-extraction piece is provided in an arc shape with two halves, and the anti-extraction piece is locked in the anti-extraction installation groove by a bolt or a buckle. Alternatively, the anti-extraction piece can be provided in a C-shaped structure and clamped in the anti-extraction installation groove through a gap.

[0017] From the above technical solutions, the present application has at least the following advantages and positive effects:

[0018] The application discloses a double-plug pipe connecting structure, wherein the pipe has two plug ends, and a anti-disengagement part is arranged on the plug end; the connecting pipe has two socket ends, and an anti-disengagement groove is arranged in the socket end; and the pipe can form a clamping structure after being connected, and has the anti-disengagement capability.

[0030] The pipe body 11 of the pipe 1 adopts the regular octagon, and the clamping section 21 of the socket end adopts the regular quadrilateral, so that the pipe 1 has four planes as placing planes, thereby being convenient for transportation and being easier to be fixed and installed. The anti-disengagement groove 211 is arranged on the four corners of the quadrilateral, which is to form the clamping connection of the anti-disengagement groove 211 and the anti-disengagement part and to specially select the placing plane.
