[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the following further elaborates the present utility model in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative labor all fall within the protection scope of the present invention.

[0022] The following describes the specific embodiments of the present utility model in conjunction with the drawings.

[0023] Embodiment 1

[0024] As Figures 1-5 shown, a sealing connector for a perforated mesh steel strip composite pipe includes a perforated mesh steel strip composite pipe 1. An inner pipe 5 is inserted into the end of the perforated mesh steel strip composite pipe 1. Sealing sleeves 6 in contact with the perforated mesh steel strip composite pipe 1 are sleeved at both ends of the inner pipe 5. Connecting pipes 2 wrapped around the outside of the perforated mesh steel strip composite pipe 1 are sleeved at both middle ends on the outside of the inner pipe 5. Connecting sleeves 4 are arranged at the ends of the two connecting pipes 2 and on the outside of the inner pipe 5. A plurality of inserting rods 3 connected to the perforated mesh steel strip composite pipe 1 are arranged on the outside of the connecting pipes 2.

[0025] The perforated mesh steel strip composite pipe 1 includes an inner layer 11, a perforated mesh steel layer 12 and an outer layer 13 sequentially sleeved on the outside of the inner layer 11.

[0026] The cross-section of the sealing sleeve 6 is L-shaped, and the sealing sleeve 6 is connected to the end face and the inner side of the perforated mesh steel strip composite pipe 1.

[0027] The number of the inserting rods 3 is at least three. A threaded hole is arranged on the outside of one end of the connecting pipe 2. The inserting rod 3 passes through the threaded hole of the connecting pipe 2 and is connected to the perforated mesh steel strip composite pipe 1.

[0028] Threads are arranged on the outside of the other end of the connecting pipe 2. Thread grooves are arranged at both inner ends of the connecting sleeve 4. The connecting sleeve 4 is sleeved on the outside of the other end of the connecting pipe 2. The two thread grooves of the connecting sleeve 4 are symmetrically arranged, and the two connecting pipes 2 are symmetrically arranged.

[0029] The lengths of the inner layer 11 and the perforated mesh steel layer 12 are greater than the length of the outer layer 13. This spacing mainly exposes the through holes of the perforated mesh steel layer 12, so that the inserting rods 3 can pass through the connecting pipes 2 and be inserted into the through holes of the perforated mesh steel layer 12. The length of the inner pipe 5 inserted into the inside of the inner layer 11 is greater than the spacing between the inner layer 11, the perforated mesh steel layer 12 and the outer layer 13. A step is arranged at the inner side of one end of the connecting pipe 2. One end of the connecting pipe 2 is wrapped around the outside of the perforated mesh steel layer 12 and the outer layer 13. This structure is used to improve the strength of the end of the perforated mesh steel strip composite pipe 1 and avoid the low strength caused by the lack of the outer layer 13 in the perforated mesh steel strip composite pipe 1. Among them, after installation, functional glue such as waterproof glue can be coated between the connecting pipe 2 and the outer layer 13 to avoid leakage between the connecting pipe 2 and the perforated mesh steel strip composite pipe 1.

[0030] A slide bar is provided on the outer side of the middle part of the inner tube 5, and a slide groove adapted to the slide bar of the inner tube 5 is provided on the inner side of the other end of the connecting tube 2. The cooperation between the slide bar and the slide groove enables the connecting sleeve 4 to move toward the middle part of the connecting sleeve 4 when the connecting sleeve 4 rotates, thereby generating a pulling force that involves the mesh steel belt composite pipe 1.

[0031] A connecting column and a sleeve are arranged on the outside of the connecting sleeve 4. This structure can be used to connect the steel pipe and the steel column, so that it drives the connecting sleeve 4 to rotate, thereby driving the distance between the two connecting pipes 2 to decrease.

[0032] Working principle:

[0033] When in use, one end of the outer layer 13 is cut off so that the length of the mesh steel layer 12 and the inner layer 11 is greater than the outer layer 13, so that the mesh steel layer 12 is exposed on the outside, the connecting sleeve 4 is sleeved on the outside of the inner tube 5, and the two connecting pipes 2 are respectively sleeved on the two ends of the inner tube 5, so that the slide groove is connected to the slide bar of the inner tube 5, and the end part of the connecting pipe 2 is threadedly connected to the connecting sleeve 4, and then the sealing sleeve 6 is sleeved on the two ends of the inner tube 5, and the inner tube 5 drives the sealing sleeve 6 to be inserted into the inner side of the mesh steel belt composite pipe 1 , so that the sealing sleeve 6 and the inner tube 5 are sealed, and at the same time, the connecting pipe 2 is sleeved on the outside of the inner tube 5 and the mesh steel strip composite pipe 1, and the plug-in rod 3 is twisted to make the end of the plug-in rod 3 inserted into the inner side of the through hole of the mesh steel layer 12, and then the connecting sleeve 4 is rotated by the tool to make the connecting pipe 2 drive the mesh steel layer 12 to move toward the middle of the inner tube 5, so that the inner layer 11 of the mesh steel strip composite pipe 1 and the end of the mesh steel layer 12 are connected to the sealing sleeve 6, so that the inner tube 5 and the mesh steel strip composite pipe 1 are further sealed, thereby improving the sealing effect.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model.
