Description

Technical Field

[0001] This utility model relates to the field of lead tube socket technology, and in particular to a tensile-resistant lead tube socket assembly. Background Technology

[0002] The lead wire socket assembly is a guide device used when a wire enters an underground pipeline. The lead wire socket assembly provides a convenient and fast lead wire introduction operation when introducing wires into the pipeline.

[0003] However, in most existing lead-in connector assemblies, after the lead-in connector enters the pipe, the installed wire needs to be connected and fixed to the other end of the connector before the wire is pulled. This is usually done by wrapping or knotting the wire to the connector body. This method is relatively cumbersome when connecting the connector to the wire; excessive winding makes subsequent wire removal inconvenient, while insufficient winding makes the wire prone to detachment during pulling. Therefore, it is necessary to propose a tensile-resistant lead-in connector assembly to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a tensile-resistant lead wire socket assembly to solve the problem mentioned in the background art: usually, after the lead wire socket assembly is installed in the pipeline, it is necessary to connect and fix the installed wire to the other end of the lead wire socket assembly and then pull the lead wire. In most cases, the wire is usually fixed by winding or knotting it to the surface of the lead wire socket assembly. This method is relatively cumbersome when connecting the lead wire socket assembly and the wire. If too much wire is wound, it will cause inconvenience for subsequent wire disassembly. If too little wire is wound, it is easy for the wire to fall off when pulling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tensile strength lead tube seat assembly, comprising a lead tube seat assembly, the lead tube seat assembly including a guide structure and a fixing structure, the fixing structure including a second fixing sleeve, a connecting sleeve, a threaded sleeve and a limiting sleeve, the side of the second fixing sleeve being fixedly connected to the side of the connecting sleeve, the inside of the connecting sleeve being threadedly connected to the outside of the threaded sleeve, the inside of the threaded sleeve being rotatably connected to the outside of the limiting sleeve, and the inside of the limiting sleeve having a pressure groove;

[0006] The side of the connecting sleeve is provided with a limiting structure, which includes a fixing plate and a limiting block. The outside of the fixing plate is fixedly connected to the outside of the connecting sleeve, and the inside of the fixing plate is slidably connected to the outside of the limiting block.

[0007] Preferably, the guide structure includes a lead wire guide, a connecting block, a pulley, and a first fixing sleeve. One side of the lead wire guide is rotatably connected to the side of the connecting block, and the other side of the lead wire guide is fixedly connected to the side of the first fixing sleeve. The connecting block and the pulley are rotatably connected via a rotating shaft.

[0008] Preferably, a spring is fixedly connected to the side of the first fixing sleeve, and one end of the spring is fixedly connected to the side of the second fixing sleeve.

[0009] Preferably, the groove is arc-shaped, and there are multiple grooves.

[0010] Preferably, a limiting groove is formed inside the threaded sleeve, and the limiting groove is inserted into the limiting block.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] By combining the fixing and limiting structures, when the lead wire guide of the guide structure passes through the pipe and the installed wire needs to be fixed to the fixing structure during the use of the lead wire socket assembly, the wire can first be passed through the inside of the threaded sleeve and the limiting sleeve, bent and suspended at the pressure groove, and then the threaded sleeve is placed inside the connecting sleeve. Rotating the threaded sleeve will cause the limiting sleeve to move, making the top of the limiting sleeve in close contact with the inside of the connecting sleeve, thereby limiting and fixing the wire suspended on the surface of the limiting sleeve, which facilitates quick and easy fixing of the wire. Furthermore, the limiting block can be used to further limit and fix the threaded sleeve, avoiding the problem of wire loosening due to slippage between the threaded sleeve and the limiting sleeve, thus further improving the stability of the wire fixing.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figures 1-3 The diagram illustrates a tensile-resistant lead wire socket assembly, comprising a lead wire socket assembly, a guide structure, and a fixing structure. The guide structure includes a lead wire guide head 1, a connecting block 2, a pulley 3, and a first fixing sleeve 4. One side of the lead wire guide head 1 is rotatably connected to the side of the connecting block 2, and the other side of the lead wire guide head 1 is fixedly connected to the side of the first fixing sleeve 4. The connecting block 2 and the pulley 3 are rotatably connected via a pivot. During use, the guide structure can be placed inside the pipe, and the pulley 3 can be used to reduce the friction between the lead wire guide head 1 and the inside of the pipe, thereby improving the passage of the lead wire guide head 1.

[0019] In addition, the fixing structure includes a second fixing sleeve 6, a connecting sleeve 7, a threaded sleeve 8, and a limiting sleeve 13. The side of the second fixing sleeve 6 is fixedly connected to the side of the connecting sleeve 7. The inside of the connecting sleeve 7 is threadedly connected to the outside of the threaded sleeve 8. The inside of the threaded sleeve 8 is rotatably connected to the outside of the limiting sleeve 13. A pressure groove 9 is opened inside the limiting sleeve 13. A spring 5 is fixedly connected to the side of the first fixing sleeve 4. One end of the spring 5 is fixedly connected to the side of the second fixing sleeve 6. The pressure groove 9 is arc-shaped, and there are multiple pressure grooves 9. When the guide head 1 of the guide structure passes through the pipe, and it is necessary to fix the installed wire to the fixed structure, the wire can first be passed through the inside of the threaded sleeve 8 and the limiting sleeve 13, and the wire can be bent and suspended at the pressure groove 9. Then, the threaded sleeve 8 is placed inside the connecting sleeve 7. Rotating the threaded sleeve 8 will cause the limiting sleeve 13 to move, so that the top of the limiting sleeve 13 is in close contact with the inside of the connecting sleeve 7, thereby limiting and fixing the wire suspended on the surface of the limiting sleeve 13, which facilitates the quick limiting and fixing of the wire.

[0020] Finally, a limiting structure is provided on the side of the connecting sleeve 7. The limiting structure includes a fixing plate 11 and a limiting block 12. The outside of the fixing plate 11 is fixedly connected to the outside of the connecting sleeve 7, and the inside of the fixing plate 11 is slidably connected to the outside of the limiting block 12. A limiting groove 10 is opened inside the threaded sleeve 8, and the limiting groove 10 is inserted into the limiting block 12. The limiting block 12 can be inserted into the limiting groove 10 to facilitate the limiting and fixing of the threaded sleeve 8, avoiding the problem of the thread slipping between the threaded sleeve 8 and the connecting sleeve 7 and causing the line to loosen, further improving the stability of the line fixing.

[0021] Working principle: During the use of the lead wire socket assembly, the guide structure is first placed inside the pipe. The pulley 3 is used to reduce the friction between the lead wire guide 1 and the inside of the pipe, thereby making the lead wire guide 1 more passable. After the lead wire guide 1 of the guide structure passes through the pipe, when it is necessary to fix the installed wire to the fixing structure, the wire can first be passed through the inside of the threaded sleeve 8 and the limiting sleeve 13. The wire is bent and suspended at the pressure groove 9. Then, the threaded sleeve 8 is placed inside the connecting sleeve 7. Rotating the threaded sleeve 8 will cause the limiting sleeve 13 to move, so that the top of the limiting sleeve 13 is in close contact with the inside of the connecting sleeve 7, thereby limiting and fixing the wire suspended on the surface of the limiting sleeve 13. This facilitates quick limiting and fixing of the wire. Then, the limiting block 12 can be inserted into the limiting groove 10 to limit and fix the threaded sleeve 8, avoiding the problem of the wire loosening due to slippage between the threaded sleeve 8 and the connecting sleeve 7, and further improving the stability of the wire fixing.
