Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement pipe products, specifically a cement pipe with a steel ring joint. Background Technology
[0002] Cement pipes, also known as cement pressure pipes or reinforced concrete pipes, can be used as drainage pipes in urban construction infrastructure. They can discharge sewage, flood control and drainage, as well as water supply pipes in some special factories and mines and farm wells. Sewer pipes are pipes used to discharge sewage or rainwater, and are used to collect and discharge domestic wastewater generated in cities and industrial wastewater generated in industries.
[0003] Cement pipes lack steel ring joints at both ends during use, resulting in poor strength at the joints between pipes and making them prone to breakage. Utility Model Content
[0004] The purpose of this utility model is to provide a cement pipe with a steel ring joint to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cement pipe with a steel ring joint, comprising a pipe body, both ends of which are fixedly fitted with steel fixing rings, the steel fixing rings having multiple insertion holes, each insertion hole having a locking screw inserted into it, both ends of the locking screws being threaded with fixing nuts, the steel fixing rings comprising a base material layer, an anti-corrosion layer fixedly connected to the outside of the base material layer, and a protective layer fixedly connected to the outside of the anti-corrosion layer.
[0006] Preferably, a sealing ring is fixedly connected to one side of the outer wall of the steel fixing ring.
[0007] Preferably, the plurality of sockets are equidistant from each other.
[0008] Preferably, the anti-corrosion layer is a PEEK resin corrosion-resistant coating.
[0009] Preferably, the protective layer is a modified silane coating.
[0010] Preferably, the fixing nut is a hexagonal nut.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This cement pipe with a steel ring joint is assembled by fitting a steel fixing ring onto the end of the pipe body, ensuring the adjacent steel fixing rings fit snugly, then inserting a locking screw into the connected socket, and finally securing it by screwing a fixing nut onto both ends of the locking screw. The steel fixing ring is corrosion-resistant due to the anti-corrosion layer on the outside of the base material layer, and the outer protective layer prevents the steel fixing ring from being attacked by chlorides. This invention adds a steel fixing ring, giving the pipe body connection an explosion-proof function, and the external protective coating of the steel fixing ring prevents wear and tear during use, thereby extending the service life of the steel fixing ring.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] Please see Figure 1-3 This utility model provides an embodiment of a cement pipe with a steel ring joint, comprising a pipe body 1, with steel fixing rings 2 fixedly fitted at both ends of the pipe body 1. The steel fixing rings 2 have multiple insertion holes 3, each containing a locking screw 4. Both ends of the locking screw 4 are threaded with fixing nuts 5. The steel fixing ring 2 includes a base material layer 6, with an anti-corrosion layer 7 fixedly connected to the outside of the base material layer 6, and a protective layer 8 fixedly connected to the outside of the anti-corrosion layer 7. Specifically, the steel fixing rings 2 are fitted onto the ends of the pipe body 1, and during assembly, adjacent steel fixing rings 2 are fitted together. Then, the locking screws 4 are inserted into the connected insertion holes 3, and the fixing nuts 5 are screwed onto both ends of the locking screws 4 to achieve fixation. The anti-corrosion layer 7 on the outside of the base material layer 6 provides corrosion resistance, and the outer protective layer 8 prevents the steel fixing rings 2 from being attacked by chlorides.
[0021] In this embodiment, a sealing ring 9 is fixedly connected to one side of the outer wall of the steel fixing ring 2 to increase the sealing effect at the connection; the multiple insertion holes 3 are equidistantly arranged; the anti-corrosion layer 7 is a PEEK resin corrosion-resistant coating; the protective layer 8 is a modified silane coating; and the fixing nut 5 is a hexagonal nut.
