Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a detachable anti-detachment socket joint for drainage and sewage pipes.
[0004] To solve the first technical problem mentioned above, the technical solution adopted by this utility model is as follows: a socket joint for drainage and sewage pipes to prevent detachment, comprising: a socket provided on one end of a drainage and sewage pipe and a socket provided on the corresponding end of another drainage and sewage pipe; the specific structure of the socket includes: a socket installation section connected to the corresponding drainage and sewage pipe, a socket splicing section with a diameter larger than the socket installation section, and a socket connecting section connecting the socket installation section and the socket splicing section, wherein the socket splicing section is located near its end. At least two operating windows are provided circumferentially at the port. The splicing section of the socket has obliquely arranged locking feet on the side wall of the operating window near its port. The specific structure of the socket includes: a splicing section and a splicing installation section that connects the splicing section to the corresponding drainage and sewage pipe. The splicing section is provided with several splicing annular bosses that mate with the inner wall of the splicing section of the socket. Furthermore, a sealing groove is formed between at least two adjacent splicing annular bosses, and a sealing ring is provided in the sealing groove.
[0005] As a preferred embodiment, in the aforementioned anti-detachment socket joint for drainage and sewage pipes, the socket splicing section has a tapered locking part with a smaller inner end and a larger outer end near its port, and all operating windows are arranged circumferentially on the tapered locking part.
[0006] As a preferred embodiment, in the aforementioned anti-detachment socket joint for drainage and sewage pipes, the angle between the clamping foot and the center line of the socket is controlled between 40 and 52°, and correspondingly, the angle between the tapered clamping part and the center line of the socket is controlled between 15 and 22°.
[0007] As a preferred embodiment, in the aforementioned anti-detachment socket joint for drainage and sewage pipes, the tapered snap-fit part has a reinforcing protrusion on its outer side facing the operating window, and the end walls of the reinforcing protrusion extend beyond the corresponding end walls of the corresponding operating window at both ends in the circumferential direction.
[0008] As a preferred embodiment, in the aforementioned anti-detachment socket joint for drainage and sewage pipes, the socket has at least three annular bosses, forming two sealing grooves.
[0009] As a preferred embodiment, in the aforementioned anti-detachment socket joint for drainage and sewage pipes, the socket connection section is tapered.
[0010] As a preferred embodiment, in the aforementioned anti-detachment socket joint for drainage and sewage pipes, a tapered socket connection section is provided between the socket splicing section and the socket installation section.
[0011] As a preferred embodiment, in the aforementioned anti-detachment socket joint for drainage and sewage pipes, a plurality of socket annular bosses are provided on the socket splicing section.
[0012] As a preferred embodiment, in the aforementioned anti-detachment socket joint for drainage and sewage pipes, the drainage and sewage pipe is a corrugated pipe.
[0013] As a preferred embodiment, in the aforementioned anti-detachment socket joint for drainage and sewage pipes, the corrugated pipe is a steel-reinforced polyethylene spiral corrugated pipe.
[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model opens an operation window on the splicing section of the socket and sets the locking foot on the side wall of the splicing section near the port. When disassembling, you only need to use a tool to pry the locking foot outward from the annular boss of the splice through the operation window to separate the splice and the socket and separate the two drainage and sewage pipes. The operation is very convenient.
[0016] 2. This utility model provides a tapered locking part near the end of the splice section of the socket, increasing the angle between the locking foot and the center line of the drainage and sewage pipe to a suitable angle, so that the locking foot can reliably act on the corresponding annular protrusion of the spigot, thereby effectively preventing the spigot from slipping out of the socket.
[0017] 3. The conical snap-fit part of this utility model has a reinforced protrusion on its outer side facing the operation window, which ensures the connection strength between the snap-fit foot and the conical snap-fit part, so that the snap-fit foot can act more reliably on the corresponding socket annular protrusion and prevent the socket from slipping out of the socket.
[0018] 4. This utility model provides at least three annular protrusions on the spigot assembly section, thereby forming two sealing grooves and further improving the sealing performance between the spigot and the socket.
[0019] 5. This utility model provides a spigot connection section between the spigot splicing section and the spigot installation section. This allows the spigot to be connected to the drainage and sewage pipe without needing to modify the size of the spigot splicing section or the structure of the socket. This greatly simplifies the design of the corresponding mold.
[0020] 6. This utility model greatly increases the strength of the socket by setting an annular boss on the splicing section of the socket, making the connection between the spigot and the socket more reliable. Attached Figure Description

[0033] The following describes in detail, with reference to the accompanying drawings, a specific implementation scheme for an anti-detachment socket joint for drainage and sewage pipes according to this utility model.
[0034] Example 1:
[0035] like Figures 1 to 5 As shown, the first type of splicing structure of this utility model is used for the anti-detachment socket joint of drainage and sewage pipes, including: a joint set at one end of a steel strip reinforced polyethylene spiral corrugated pipe 2. Figure 3 The socket 32 on the left end of the middle) and the corresponding end of the other steel strip reinforced polyethylene spiral corrugated pipe 1 ( Figure 3 Socket 31 on the right end of the middle port; such as Figure 5 As shown, the specific structure of the socket 31 includes: a socket installation section 311 connected to the right end of the steel-reinforced polyethylene spiral corrugated pipe 1; a socket splicing section 315 with a diameter larger than that of the socket installation section 311; and a socket connecting section 313 connecting the socket installation section 311 and the socket splicing section 315. The socket connecting section 313 is conical. The socket splicing section 315 has a conical snap-fit part 317 with a smaller inner end and a larger outer end near its end. To simplify the mold design (without core pulling), four operating windows 3171 are symmetrically opened on the conical snap-fit part 317. The conical snap-fit part 317 is located on its outer side ( Figure 6On the right side of the operating window 3171, a reinforcing protrusion 319 is provided. The end walls of the reinforcing protrusion 319 extend beyond the corresponding end walls of the corresponding operating window 3171 in the circumferential direction. A tapered locking part 317 is located on the side of the operating window 3171 near its port. Figure 6 On the right side wall of the socket 31, obliquely arranged retaining feet 318 are provided downward and inward. The angle β between the retaining feet 318 and the center line of the socket 31 is controlled between 40 and 52°. Correspondingly, the angle α between the tapered retaining part 317 and the center line of the socket 31 is controlled between 15 and 22°. The spigot 32 includes: a spigot splicing section 325, a spigot installation section 321 connected to the steel strip reinforced polyethylene spiral corrugated pipe 2, and a spigot connecting section 323 connecting the spigot splicing section 325 and the spigot installation section 321. The spigot connecting section 323 is tapered. The spigot splicing section 325 is provided with a joint that connects with the socket 31. The inner walls of the splicing section 315 of the socket are fitted with a first socket annular boss 3251, a second socket annular boss 3252, a third socket annular boss 3253, a fourth socket annular boss 3254, a fifth socket annular boss 3255, and a sixth socket annular boss 3256. Sealing grooves are formed between the first socket annular boss 3251 and the second socket annular boss 3252, and between the third socket annular boss 3253 and the fourth socket annular boss 3254, respectively. Sealing rings 33 are provided in the sealing grooves. The splicing section 315 of the socket 31 is provided with four socket annular bosses 3151 as reinforcing ribs.
[0036] In practical applications, Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The socket 31 in the anti-detachment socket joint is directly connected to the corresponding port of the steel strip reinforced polyethylene spiral corrugated pipe 1 during injection molding. Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The socket 32 in the anti-detachment socket joint is directly connected to the corresponding port of the steel-reinforced polyethylene spiral corrugated pipe 2 during injection molding; and Figure 4 The socket and spigot of the anti-detachment socket joint shown are both independent plastic parts, which are heat-fused together with the corresponding pipe fittings during installation.
[0037] Example 2:
[0038] like Figures 7 to 9 As shown, the second type of anti-detachment socket joint for drainage and sewage pipes described in this utility model is the same as the structure in Embodiment 1, except that a wider annular reinforcing edge 310 is provided on the outside of the tapered snap-fit part 317, and will not be described again here.
[0039] In practical applications, Figure 7 and Figure 8 The socket 31 in the anti-detachment socket joint is directly connected to the corresponding port of the steel strip reinforced polyethylene spiral corrugated pipe 1 during injection molding. Figure 7 and Figure 8 The socket 32 in the anti-detachment socket joint is directly connected to the corresponding port of the steel-reinforced polyethylene spiral corrugated pipe 2 during injection molding; and Figure 9 The socket and spigot of the anti-detachment socket joint shown are both independent plastic parts, which are heat-fused together with the corresponding pipe fittings during installation.
[0040] During actual installation, simply insert the spigot 32 on the steel-reinforced polyethylene spiral corrugated pipe 2 directly into the socket 31 on the steel-reinforced polyethylene spiral corrugated pipe 1. For disassembly, simply use a tool to pry the retaining clip 318 outward from the sixth spigot annular boss 3256 through the operating window 3171 to separate the spigot 32 and socket 31, thus separating the two steel-reinforced polyethylene spiral corrugated pipes 1 and 2. The operation is very convenient.

[0042] like Figure 10 As shown, the third type of anti-detachment socket joint for drainage and sewage pipes described in this utility model differs from that in Embodiment 1, except for the socket installation section and spigot installation section used for connecting with ordinary pipe fittings. Figure 4 The independent anti-detachment sockets shown have the same structure, so they will not be described again here.
[0043] Example 4:
[0044] like Figure 11 As shown, the fourth type of anti-detachment socket joint for drainage and sewage pipes described in this utility model differs from that in Embodiment 2, except for the socket installation section and spigot installation section used for connecting with ordinary pipe fittings. Figure 9 The independent anti-detachment sockets shown have the same structure, so they will not be described again here.
