Description

Technical Field

[0001] The utility model relates to the technical field of steel wire skeleton polyethylene composite pipes, in particular to a steel wire skeleton polyethylene composite pipe. Background Art

[0002] The wire mesh skeleton polyethylene composite pipe is a new type of pipe with a mesh skeleton formed by spirally winding high-strength steel wire as the reinforcement, high-density polyethylene (HDPE) as the matrix, and high-performance HDPE modified adhesive resin to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene, so that it has higher pressure resistance. At the same time, the composite pipe has excellent flexibility and is suitable for long-distance buried water supply and gas pipeline systems. The fittings used in the wire mesh skeleton polyethylene composite pipe are polyethylene electric fusion fittings. When connecting, the heating element inside the fittings is used to melt the outer plastic layer of the pipe and the inner plastic layer of the fittings, so that the pipe and the fittings are reliably connected together.

[0003] However, when existing wire mesh skeleton polyethylene composite pipes are buried and connected, most of them use the heating element inside the pipe fitting to melt the outer plastic of the pipe with the inner plastic of the pipe fitting to reliably connect the pipe and the fitting together. However, such a connection is a fixed connection, which is time-consuming and affects the installation efficiency. In addition, this connection method makes the pipes merge into one, which improves the sealing performance. However, during the subsequent inspection and maintenance of the pipes, the pipes cannot be quickly disassembled, which affects the maintenance efficiency. Therefore, we proposed a wire mesh skeleton polyethylene composite pipe to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 The utility model provides a technical solution: a steel wire skeleton polyethylene composite pipe, comprising a first connecting pipe 1, a first connecting sleeve 2, a first card slot 3, a second connecting pipe 4, a second connecting sleeve 5, a threaded groove 6, a first rotating shaft 7, a clamping ring 8, a second rotating shaft 9, a spring 10, a limit rod 11, a threaded rod 12, a connecting rod 13 and a connecting block 14, the first connecting pipe 1 is connected to the first connecting sleeve 2, and the first connecting sleeve 2 is provided with a first card slot 3, and the first card slot 3 is connected to the second connecting sleeve 5, and the second connecting sleeve 5 is connected to the first connecting sleeve 5. A second connecting pipe 4 is connected, a first rotating shaft 7 is provided on the first connecting sleeve 2, and a clamping ring 8 is connected to the outside of the first rotating shaft 7, and a threaded groove 6 is provided in the first connecting sleeve 2, a second rotating shaft 9 is provided at the bottom of the first connecting sleeve 2, and a limiting rod 11 is provided on the second rotating shaft 9, and a spring 10 is provided at the front end of the limiting rod 11, a threaded rod 12 is connected in the threaded groove 6, and a connecting block 14 is connected to the outside of the threaded rod 12, and a connecting rod 13 is connected to the connecting block 14, and the connecting rod 13 is connected to the clamping ring 8.

[0022] The first connecting tube 1 forms a connecting structure with the second connecting sleeve 5 on the second connecting tube 4 through the first groove 3 on the first connecting sleeve 2, thereby connecting the first connecting tube 1 and the second connecting tube 4. At the same time, an airtight gasket is arranged at the connection to avoid leakage problems, and the cross-section of the second connecting sleeve 5 is "T"-shaped, which is convenient for subsequent extrusion of the second connecting sleeve 5 to improve the tightness of the airtight gasket, and the outer ring of the second connecting sleeve 5 is a conical structure, so that when the clamping ring 8 is pressed down, the second connecting sleeve 5 is more tightly connected to the first connecting sleeve 2.

[0023] The clamping ring 8 forms a movable structure with the first connecting sleeve 2 via the first rotating shaft 7 , so that the clamping ring 8 can be driven to rotate on the first connecting sleeve 2 via the connecting rod 13 .

[0024] The limiting rod 11 forms a rotating structure at the bottom of the first connecting sleeve 2 through a spring 10 and a threaded rod 12, and the end of the limiting rod 11 is arranged at the threaded groove 6 on the lower side of the first connecting sleeve 2, so that the limiting rod 11 can be rotated at the bottom of the first connecting sleeve 2 by being squeezed by the end threaded rod 12, and can be reset by the spring 10 when no force is applied, and the limiting rod 11 is "L"-shaped, so that the bottom of the second connecting sleeve 5 can be limited by rotation.

[0025] The connecting block 14 and the threaded rod 12 are fixedly connected, so that the connecting block 14 drives the connecting rod 13 connected through the rotating shaft to move, and the connecting rod 13 forms a movable structure with the threaded rod 12 through the connecting block 14, so that the clamping ring 8 connected to the bottom through the rotating shaft is driven to open and close through the movement of the threaded rod 12.

[0026] A through hole is provided on the surface of the second connecting sleeve 5 , and the through hole is on the same horizontal line as the thread groove 6 in the first connecting pipe 1 , so that when the threaded rod 12 moves up and down, the second connecting sleeve 5 placed in the first connecting sleeve 2 can be limited to a certain position.

[0027] Working principle: When using the steel wire skeleton polyethylene composite pipe, first, manually lift the second connecting pipe 4 through an engineering machine, and then push the second connecting pipe 4 so that the "T"-shaped second connecting sleeve 5 at the front end of the second connecting pipe 4 is inserted into the first card groove 3 in the first connecting sleeve 2 of the front first connecting pipe 1. At the same time, before docking, align the position of the hole at the front end of the second connecting sleeve 5 with the position of the threaded rod 12;

[0028] Then, the threaded rod 12 on the outside of the first connecting tube 1 is rotated so that the threaded rod 12 drives the connecting block 14 and the connecting rod 13 connected by the rotating shaft to move downward, thereby driving the connecting rod 13 to close downward through the clamping ring 8 connected by the rotating shaft, so that the clamping ring 8 squeezes the protrusions on the outside of the connected first connecting sleeve 2 and the second connecting sleeve 5, thereby completing the fixation between the first connecting sleeve 2 and the second connecting sleeve 5, making the first connecting sleeve 2 and the second connecting sleeve 5 connected more tightly, and while the threaded rod 12 moves downward, the threaded rod 12 passes through the threaded groove 6 on the first connecting sleeve 2 and penetrates the front section of the second connecting sleeve 5, and finally squeezes the end of the limiting rod 11 at the bottom of the first connecting sleeve 2. Through the squeezing of the threaded rod 12, the front section of the limiting rod 11 is lifted by the second rotating shaft 9, so that the protrusions at the front end clamp all the protrusions in the second connecting sleeve 5, thereby realizing the limitation of the second connecting sleeve 5, which makes the first connecting tubes 1 tightly connected, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
