Description

Technical Field

[0001] This utility model relates to a pipe connection device, specifically a water supply and drainage pipe connector. Background Technology

[0002] The core function of pipe connectors is to achieve reliable pipe connections. They mainly connect two adjacent pipe sections into a whole, ensuring the normal flow of water in water supply and drainage pipes.

[0003] Existing pipe connectors include rubber sealing liners, but these liners are all smoothly designed. The smooth rubber liner makes surface contact with the outer wall of the pipe, and the seal relies on the uniform transmission of overall pressure. However, the pipe joint (the gap where two pipes meet) is the core area with the highest risk of leakage. Smooth liners cannot effectively concentrate pressure at this location, easily leading to insufficient sealing due to pressure dispersion.

[0004] In addition, if the pipe has minor diameter deviations (such as manufacturing errors), uneven outer walls, or slight ellipticity, or if the smooth inner lining does not fit well with the pipe, gaps may easily appear in some areas, leading to an increased risk of leakage. Utility Model Content

[0005] The main purpose of this utility model is to provide a water supply and drainage pipe connector that solves the problems of insufficient sealing reliability and poor adaptability of existing smooth inner lining connectors.

[0006] To achieve the above objectives, this utility model provides a water supply and drainage pipe connector, comprising: A ring-shaped metal shell, comprising an upper shell and a lower shell, wherein one end of the upper shell and the lower shell are hinged together, and the other end of the upper shell and the lower shell are fixedly connected by fasteners; The inner wall of the rubber sealing liner is fitted to the inner wall of the metal shell. The middle part and both sides of the inner wall of the rubber sealing liner are provided with protrusions. The protrusion in the middle part of the rubber sealing liner is pressed against the connection of the two water supply and drainage pipes.

[0007] Preferably, the fasteners include bolts and nuts, with the bolts and nuts being screwed together.

[0008] More preferably, the free end of the upper shell is provided with an upper connecting plate, and the upper connecting plate is provided with an upper through hole; The free end of the lower housing is provided with a lower connecting plate, and the lower connecting plate is provided with a lower through hole; One end of the bolt passes through the upper through hole and the lower through hole in sequence before being screwed onto the nut.

[0009] Preferably, the free end of the upper shell is provided with multiple tooth grooves, and the free end of the lower shell is provided with teeth that match the tooth grooves, and the teeth can fill the tooth grooves.

[0010] Preferably, the rubber sealing liner is composed of a first arc-shaped liner and a second arc-shaped liner joined together.

[0011] Preferably, the curvature of the first arc-shaped inner lining is greater than that of the second arc-shaped inner lining.

[0012] More preferably, the first arc-shaped inner lining has an opening, and the second arc-shaped inner lining is fastened to the opening.

[0013] The beneficial effects of this utility model are as follows: 1. Enhances pressure concentration and fit Under the clamping force of the metal shell, the raised structure of the rubber sealing liner will produce a larger local deformation than that of the smooth liner (when the raised part is compressed, the stress is concentrated at the top of the raised part), which makes the clamping force of the middle raised part on the interface gap stronger and the fit of the raised parts on both sides to the outer wall of the pipe tighter, thus solving the problem of "pressure dispersion and local loose connection" of the smooth liner.

[0014] 2. Multiple seals enhance sealing reliability. The raised section in the middle of the rubber sealing liner forms a "main sealing line" against the interface gap, while the raised sections on both sides form "auxiliary sealing lines" against the outer wall of the pipe, thus creating a "triple sealing defense." Even if the main seal experiences minor wear due to long-term use, the auxiliary seals can still prevent media leakage and reduce the risk of leakage.

[0015] 3. Adapt to pipeline errors When there are slight diameter deviations or unevenness on the outer wall of the pipe, the protrusion can achieve a tight fit by adjusting its own compression. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1 As shown, this embodiment provides a water supply and drainage pipe connector, including a metal shell 100 and a rubber sealing liner 200. Both the metal shell 100 and the rubber sealing liner 200 are annular. The rubber sealing liner 200 is fitted inside the metal shell 100, and the outer wall of the rubber sealing liner 200 is fitted against the inner wall of the metal shell 100. The rubber sealing liner 200 is fitted onto the outside of the water supply and drainage pipe. By tightening the metal shell 100, the rubber sealing liner 200 is pressed tightly against the outside of the water supply and drainage pipe, thereby achieving a seal between two adjacent water supply and drainage pipes.

[0021] Specifically, in this embodiment, such as Figure 1 , Figure 4 and Figure 5 As shown, the metal casing 100 includes an upper casing 110 and a lower casing 120. One end of the upper casing 110 and the lower casing 120 are hinged together by a pivot 130, and the other end of the upper casing 110 and the lower casing 120 are fixedly connected by fasteners. Preferably, in this embodiment, the fasteners include bolts and nuts, and the bolts and nuts are screwed together.

[0022] Specifically, in this embodiment, the free end of the upper housing 110 is provided with an upper connecting plate 111, and the upper connecting plate 111 is provided with an upper through hole 1111. The free end of the lower housing 120 is provided with a lower connecting plate 121, and the lower connecting plate 121 is provided with a lower through hole 1211. One end of the bolt passes through the upper through hole 1111 and the lower through hole 1211 in sequence and is screwed to the nut, thereby achieving a fixed connection between the upper housing 110 and the lower housing 120 through the cooperation of the bolt and the nut.

[0023] In addition, in this embodiment, the free end of the upper housing 110 is provided with a plurality of grooves 112, and the free end of the lower housing 120 is provided with teeth 122 that match the grooves 112, and the teeth 122 can fill into the grooves 112. In this way, the interlocking structure achieves the effect of strengthening the connection stability.

[0024] In this embodiment, as Figures 1 to 3 As shown, the rubber sealing liner 200 has protrusions 212 in the middle and on both sides. The protrusions 212 in the middle of the rubber sealing liner 200 are pressed against the connection of the two water supply and drainage pipes.

[0025] In this embodiment, the rubber sealing liner 200 is formed by splicing a first arc-shaped liner 210 and a second arc-shaped liner 220. Preferably, the curvature of the first arc-shaped liner 210 is greater than that of the second arc-shaped liner 220. An opening 211 is provided in the first arc-shaped liner 210, and the second arc-shaped liner 220 is fastened onto the opening 211. During installation, the first arc-shaped liner 210 can be first fitted onto the outer end of the water supply and drainage pipe, then the second arc-shaped liner 220 can be installed at the opening 211 of the first arc-shaped liner 210, and finally the upper shell 110 and lower shell 120 can be closed, thus facilitating the installation of the rubber sealing liner 200.

[0026] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
