[0016] 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: a waterproof and sealed indoor electrical conduit connection device, including a pipe body 1, a sealing ring 2, an elastic support 3, an outer cover 4, a positioning and locking mechanism 5, and a snap-fit ​​block 6. The pipe body 1 has internal threads at both ends for connecting to the electrical conduit. The sealing ring 2 consists of an outer sealing ring 2a and an inner sealing ring 2b, forming a two-layer structure, respectively installed at both ends of the pipe body 1. The inner end of the outer sealing ring 2a is tightly fitted to the interior of both ends of the pipe body 1, and the inner sealing ring 2b is located inside the outer sealing ring 2a, with the two connected by the elastic support 3. The positioning and locking mechanism 5 is located on both sides of both ends of the pipe body 1 for tightly locking the sealing ring 2. The outer cover 4 covers the outer side of the positioning and locking mechanism 5. The device is connected to the pipe body 1 via snap-fit ​​blocks 6. The internal threads at both ends of the pipe body 1 ensure a secure connection with the electrical conduit. Once installed, the elastic support 3 provides necessary cushioning when the external environment changes or is subjected to vibration, effectively absorbing and dispersing energy and preventing the sealing components from loosening due to vibration. The outer sealing ring 2a fits tightly against the inside of the pipe body 1, forming the first line of defense against moisture intrusion. Simultaneously, the inner sealing ring 2b further enhances the waterproof performance. This double-layer design significantly improves the overall waterproof sealing effect. The positioning and locking mechanism 5 is located at both ends of the pipe body 1, tightly locking the sealing components to ensure a high degree of sealing even under fluctuating external conditions. The outer casing 4 not only provides an additional protective barrier for the internal components, preventing interference from external substances, but also ensures the integrity and stability of the entire device. Overall, this device effectively solves the problem of leakage caused by the aging and failure of sealing materials due to connection methods in existing technologies. It also improves vibration resistance, reduces the risk of cable damage, short circuits, or power outages, and eliminates potential safety hazards, thus ensuring long-term stability and safety. Both the outer sealing ring 2a and the inner sealing ring 2b are circular structures with an outer diameter slightly smaller than the inner diameter of the tube body 1. This structure allows the outer sealing ring 2a and the inner sealing ring 2b to accommodate slight dimensional differences while providing effective sealing, ensuring good adaptability and elasticity. The support member 3 is composed of multiple spring steel sheets, which are distributed in a fan shape between the outer sealing ring 2a and the inner sealing ring 2b. This structure allows the spring steel sheets to effectively absorb and disperse external pressure or vibration when the device is subjected to such forces. Furthermore, due to the fan-shaped distribution of the spring steel sheets, they provide uniform support force in different directions, ensuring proper spacing and tight contact between the outer sealing ring 2a and the inner sealing ring 2b. This maintains a good sealing effect even under irregular pressure distribution or slight installation deviations. The positioning and locking mechanism 5 includes two clamping arms 5a. A threaded cylinder 5b is welded and fixed to the middle of the outer wall of each clamping arm 5a. A positioning pin 5c is inserted inside the threaded cylinder 5b.Furthermore, the ends of the tube body 1 are symmetrically provided with threaded holes that match the structure of the positioning pin 5c. The clamping arm 5a has an overall arc-shaped structure, and the inner end of the clamping arm 5a is connected to the ends of the tube body 1 via a hinge. This clamping arm 5a can rotate at the end of the tube body 1 via the hinge to adjust the opening and closing degree until pressure is applied and it fits against the outer wall of the outer end of the sealing ring 2. The positioning pin 5c passes through the threaded cylinder 5b and is screwed into the threaded hole on the tube body 1 to complete the limiting and locking of the sealing ring 2, ensuring a better contact between the sealing ring 2 and the tube body 1. The locking blocks 6 are evenly welded and fixed to the outer walls of both ends of the pipe body 1 to ensure a tight fit and effectively prevent any possible loosening or displacement. The inner end of the outer cover 4 is provided with several locking grooves that match the structure of the locking blocks 6. This structure allows the locking blocks 6 to be firmly embedded in the locking grooves by aligning them with the locking grooves on the outer cover 4, pressing gently, and tightening with bolts. This creates a tight connection, facilitating quick installation and disassembly, and providing additional safety by preventing the outer cover 4 from loosening or falling off due to accidental impacts or vibrations.

[0018] Working principle: When using this waterproof and sealed indoor electrical conduit connection device, firstly, align the internal threads at both ends of the pipe body 1 with the electrical conduit to be connected and tighten them to ensure the stability of the basic connection. Then, install the outer sealing ring 2a and the inner sealing ring 2b of the sealing ring 2 at both ends of the pipe body 1. In this way, the sealing ring 2 forms the first line of defense through the outer sealing ring 2a, while the inner sealing ring 2b further enhances the waterproof performance. The elastic support 3 can provide necessary cushioning when the external environment changes or is subjected to vibration. Then, the clamping arm 5a on the positioning and locking mechanism 5 is connected by a hinge. Rotate the pipe body 1 at both ends along the opening so that its inner side presses against the outer side of the sealing ring 2. Then, use the positioning screw 5c to pass through the threaded cylinder 5b and screw it into the threaded holes symmetrically arranged at both ends of the pipe body 1 to lock the sealing ring 2. After that, cover the outer cover 4 on the outside of the positioning and locking mechanism 5, so that the snap-fit ​​groove provided around the inner end of the outer cover 4 is aligned with the snap-fit ​​blocks 6 evenly distributed on the outer walls of both ends of the pipe body 1, and press gently until the two are firmly joined. In this way, the entire device not only realizes the stable connection between the electrical conduits, but also provides an additional protective barrier for the internal components, thereby completing a series of tasks.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
