[0002] Steel is an iron material; plastic refers to plastics. The plastic in steel-plastic composite pipes is generally high-density polyethylene. Steel-plastic composite pipes are a new type of composite pipe material. Steel-plastic composite pipes have higher pressure bearing capacity than ordinary plastic pipes and are more convenient to install and construct. Therefore, they are increasingly widely used in engineering projects and can be used for the transportation of oil and natural gas, industrial and mining pipes, drinking water pipes, drainage pipes, etc.

[0003] In the prior art, after the pipes are buried underground or embedded in the wall, due to the light weight of the pipe fittings and the integrated pipeline, they are easily affected by the tension of the pipeline and the pressure of the covering layer, causing position changes, affecting the direction of the pipeline design and bringing inconvenience to the construction. At the same time, since the production process of the pipes is relatively simple, pipes with antibacterial function in the inner layer are also used in the market, but ordinary pipe fittings without antibacterial function are still used for connection, which will affect the antibacterial effect of the entire pipeline system. Therefore, it is urgent to design a steel-plastic composite pipe fitting with antibacterial and anti-slip functions to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a steel-plastic composite pipe fitting with antibacterial and anti-slip functions to solve the problem raised in the above-mentioned background technology that due to the light weight of the pipe fitting and the pipeline being connected as one, it is easy to be affected by the tension of the pipeline and the pressure of the covering layer to cause position change, affecting the direction of the pipeline design and bringing inconvenience to the construction. At the same time, since the production process of the pipe is relatively simple, the pipe with antibacterial function in the inner layer is also used in the market, but ordinary pipe fittings without antibacterial function are still used for connection, which will affect the antibacterial effect of the entire pipeline system.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting up anti-slip reinforcement ribs, the strength of the main body of the pipe can be increased, and the contact area between the pipe and the covering can be increased, so that when large-diameter pipes are buried, the bonding degree between the pipe and the covering can be increased, so that the pipe is not easy to shift, which is convenient for better construction. At the same time, by setting up the nano-antibacterial layer, the growth and reproduction of Escherichia coli and Staphylococcus aureus can be inhibited, thereby ensuring the cleanliness and sanitation of the entire pipeline system. By setting up the limit support, it can play a role in limiting the connection, and can also reduce the overall weight of the pipe and reduce the use of raw materials.

[0015] 2. By setting the baffle, the fluid will not cause direct impact on the inner wall of the inner cavity pressure-bearing layer when passing through the turning point of the inner cavity pressure-bearing layer, which can avoid the inner wall of the inner cavity pressure-bearing layer from being ruptured due to excessive impact, and can achieve protection of the inner cavity pressure-bearing layer, which is beneficial to extend the service life of the pipe fittings. By setting the spring, the impact can be alleviated to a certain extent when the baffle is impacted, thereby reducing the damage to the baffle and the inner cavity pressure-bearing layer caused by the impact.

[0024] The surface of the outer cavity pressure-bearing layer 1 is provided with an anti-slip mechanism, and the anti-slip mechanism includes anti-slip reinforcement ribs 2, and the anti-slip reinforcement ribs 2 are fixedly connected to the surface of the outer cavity pressure-bearing layer 1. The surface of the outer cavity pressure-bearing layer 1 is fixedly connected with a first metal skeleton reinforcement layer 21, and the surface of the inner cavity pressure-bearing layer 11 is fixedly connected with a second metal skeleton reinforcement layer 22. The inner wall of the outer cavity pressure-bearing layer 1 is fixedly connected with a limited support 23, and the inner wall of the inner cavity pressure-bearing layer 11 is provided with a nano-antibacterial layer 24, and the nano-antibacterial layer 24 is formed by a nano-silver antibacterial agent. Through the setting of the nano-antibacterial layer 24, the inner cavity pressure-bearing layer 11 has antibacterial and antibacterial functions, which can effectively kill or inhibit the growth and reproduction of Escherichia coli and Staphylococcus aureus.

[0025] Furthermore, the anti-skid reinforcement ribs 2 are evenly distributed in a circular array on the surface of the outer cavity pressure-bearing layer 1, and the first metal skeleton reinforcement layer 21 and the second metal skeleton reinforcement layer 22 are respectively arranged in a circular shape on the surfaces of the outer cavity pressure-bearing layer 1 and the inner cavity pressure-bearing layer 11. Through the arrangement of the anti-skid reinforcement ribs 2, the contact area and strength between the outer cavity pressure-bearing layer 1 and the earth and sand can be increased during underground construction.

[0026] Furthermore, one end of the limiting support 23 is fixedly connected to the outer cavity pressure-bearing layer 1, and the other end of the limiting support 23 is fixedly connected to the inner cavity pressure-bearing layer 11. Through the setting of the limiting support 23, it can play a limiting role when the pipe and the pipe fitting are socket-connected, and at the same time it can also reduce the overall weight of the pipe fitting, reduce the use of raw materials, and reduce costs.

[0027] Furthermore, a protective mechanism is provided on the inner side of the inner cavity pressure-bearing layer 11, and the protective mechanism includes a fixed block 3, which is fixedly connected to the inner wall of the inner cavity pressure-bearing layer 11, and a first movable rod 31 is movably connected to the surface of the fixed block 3, and a second movable rod 32 is movably connected to the surface of the first movable rod 31, and a baffle 33 is movably connected to the end of the second movable rod 32 away from the first movable rod 31, and a spring 34 is fixedly connected to the surface of the second movable rod 32.

[0031] When the fluid flows on the inner side of the inner cavity pressure-bearing layer 11 and passes through the turning point of the inner cavity pressure-bearing layer 11, it will impact the baffle 33. The setting of the baffle 33 can prevent the fluid from directly impacting the inner wall of the inner cavity pressure-bearing layer 11 when passing through the turning point, thereby protecting the inner cavity pressure-bearing layer 11. At the same time, the impact on the baffle 33 will cause the second movable rod 32 and the first movable rod 31 to move, and then the spring 34 will be deformed, and the spring 34 can absorb the impact force to a certain extent.
