However, the existing JDG conduit connection methods are prone to generating gaps during the concrete pouring process, resulting in cement slurry seeping into the conduit, increasing the difficulty and cost of subsequent wire threading. Therefore, an improved connection mechanism is needed to solve this problem. Summary of the Utility Model

[0003] In order to solve the problems existing in the prior art, the utility model provides a JDG conduit connection mechanism, which combines a heat-shrinkable sleeve, a self-locking structure and a quick-locking device to prevent cement slurry from seeping into the conduit and improve the construction efficiency and sealing performance.

The inner side of the conduit interface is provided with a guide groove. A self-locking bolt and a spring mechanism are arranged on the guide groove. The self-locking bolt is connected with the spring mechanism. The locking mechanism is a buckle. The buckle is provided with a spring buckle and a locking buckle. The locking hook catches the outer wall of the JDG conduit under the action of the spring buckle.

[0006] As an improvement of the utility model, the heat-shrinkable sleeve is of a double-layer structure, with the outer layer being polyolefin and the inner layer being a waterproof adhesive layer.

[0007] As an improvement of the utility model, the inner wall of the heat-shrinkable sleeve is provided with grooves. Further, grooves can be opened on the JDG conduit so that the heat-shrinkable sleeve can be better embedded in these grooves during shrinkage, enhancing the fixing and sealing effects.

[0008] As an improvement of the utility model, a sealing ring is further provided on the conduit interface. The sealing ring is made of rubber or silica gel. When the JDG conduit is inserted into the connection sleeve, the sealing ring provides additional sealing protection to prevent cement slurry from entering the conduit.

[0011] The beneficial effects of the present utility model are as follows:

[0012] This application adopts a double-layer heat shrinkable sleeve design. The outer layer provides mechanical protection, and the inner layer melts and fills the gaps when heated to form a high seal, preventing cement slurry from seeping into the conduit. The combination of the guiding groove, self-locking pin and spring mechanism realizes the automatic locking of the conduit, ensuring the firm connection of the conduit, reducing the risk of loosening, and enhancing the safety and reliability of the connection. The groove design on the inner wall of the heat shrinkable sleeve increases the fitting area between the conduit and the connecting sleeve, further improving the stability and sealing performance of the connection. This application is also provided with a quick locking mechanism. Through the snap design, the quick installation and disassembly of the conduit are realized, with simple operation, improving the construction efficiency and reducing the labor cost.

[0020] Embodiment 1

[0021] A JDG conduit connection mechanism includes a heat shrinkable sleeve 1 and a locking mechanism. On both sides of the heat shrinkable sleeve 1, there are conduit interfaces 2. Inside the conduit interfaces 2, there are guide grooves 3. On the guide grooves 3, there are self-locking pins 4 and spring mechanisms 5. The self-locking pins 4 are connected to the spring mechanisms 5. The locking mechanism is a buckle 7. On the buckle 7, there are spring catches 8 and locking catches. The locking hook 9 catches the outer wall of the JDG conduit under the action of the spring catch 8. The heat shrinkable sleeve 1 is a double-layer structure. The outer layer 11 is made of polyolefin, and the inner layer 12 is a waterproof adhesive layer.

[0022] When connecting two JDG conduits, first insert the end of the conduit into the conduit interface 2 of the connection sleeve. The guide groove 3 guides the conduit to align with the self-locking pin 4. After the conduit is pushed in, the self-locking pin 4 pops out under the action of the spring mechanism 5 and snaps into the groove of the conduit, forming a firm locking connection. Then, put the double-layer heat shrinkable sleeve 1 outside the connection sleeve to cover the interfaces of the connection sleeve and the conduit. Use a hot air gun to heat the heat shrinkable sleeve 1 so that it shrinks and tightly adheres to the outer walls of the conduit and the connection sleeve. At the same time, the inner layer 12 of the waterproof adhesive layer melts and fills the gaps.

[0023] Embodiment 2

[0024] On the basis of Embodiment 1, the inner wall of the heat shrinkable sleeve 1 at the connection part is provided with grooves to improve the fixing and sealing performance of the conduit. A sealing ring 6 is provided on the conduit interface 2 to further enhance the sealing effect. The conduit is fixed at a predetermined position through the mounting holes 10 and bolts to ensure a stable connection.

[0025] Embodiment 3

[0026] According to the actual construction requirements, heat shrinkable sleeves 1 of different lengths can be selected. The recommended length is 8 cm to ensure sufficient coverage and sealing effect.

[0027] Specifically, the working process of the present utility model is as follows:

[0028] Install the connecting sleeve. First, ensure that the end of the conduit is clean and free of oil and grease. Then, slip the connecting sleeve over the ends of the two conduits, insert the end of the conduit into the connecting sleeve, and the guiding groove 3 guides the conduits to align with the self-locking pin 4. After the conduit is pushed in, the self-locking pin 4 pops out under the action of the spring mechanism 5 and snaps into the groove of the conduit, forming a firm locking connection. Use a hot air gun to heat the heat-shrinkable sleeve 1 so that it shrinks and tightly adheres to the outer walls of the conduit and the connecting sleeve. At the same time, the inner waterproof adhesive layer 12 melts and fills the gaps. Use the spring buckle 8 and the locking hook 9 on the buckle 7 to fix the connecting sleeve to the conduit to ensure a firm connection of the conduit.

[0029] Through the above work process, the utility model realizes efficient, safe and reliable JDG conduit connection, prevents cement slurry from seeping into the conduit, and improves the construction efficiency and sealing performance.

[0030] It should be noted that the drawings only illustrate the technical idea of the utility model, and the protection scope of the utility model cannot be limited by this shape. For those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and retouches can be made, and these improvements and retouches all fall within the protection scope of the claims of the utility model.
