For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The following is a further detailed description of a spring-assisted sliding bridge sealing door of the present invention in conjunction with the accompanying drawings.

[0027] Combined with Figure 1-7 , the present invention is introduced in detail.

[0028] A sliding bridge sealed door with spring assist comprises a door leaf 1, a door frame 2, a slideway 3, a spring guide assembly 4, a sliding shaft 5, a guide shaft and a decorative plate 6. The door leaf 1 is provided with a door handle 7 for easy manual operation; the door frame 2 is wrapped with a decorative plate 6 to improve the aesthetics; the slideway 3 is arranged on one side of the door frame 2 to guide the sliding of the door leaf 1; the spring guide assembly 4 is arranged on the other side of the door frame 2, opposite to the slideway, to provide assist for the door leaf 1.

[0029] The slideway 3 includes an inclined slideway 8 and a flat slideway 9, which are smoothly connected. The design of the inclined slideway 8 enables the door leaf 1 to be opened with the help of the force of the spring guide assembly 4 at the initial opening stage, thereby reducing the initial opening force; the flat slideway 9 ensures the stability of the door leaf 1 during the subsequent sliding process.

[0030] The spring guide assembly 4 is composed of a vertical guide shaft 10, a horizontal guide shaft 11 and a spring sliding assembly 12. The vertical guide shaft 10 is fixed to both sides of the door frame 2 to provide support for the horizontal guide shaft 11; the two ends of the horizontal guide shaft 11 are respectively slidably connected with the two vertical guide shafts 10 to form a stable horizontal sliding track; the spring sliding assembly 12 is sleeved on the horizontal guide shaft 11 to provide assistance to the door leaf 1 through the elastic force of the spring.

[0031] The spring sliding assembly 12 includes a first slider 13, a spring 14 and a second slider 15. The first slider 13 and the second slider 15 are both sleeved on the horizontal guide shaft 11 and can slide freely along the horizontal guide shaft; the spring 14 is sleeved on the horizontal guide shaft 11, and the two ends are respectively connected to the first slider 13 and the second slider 15 to form an elastic connection. When the door leaf 1 is subjected to external thrust or internal spring force, the spring sliding assembly 12 can slide along the horizontal guide shaft 11, thereby driving the door leaf 1 to open or close.

[0032] In order to further improve the assistance and stability, the spring sliding components 12 in the present invention can be arranged in two or more rows in parallel, so that the door leaf 1 is more evenly stressed during the opening and closing process and the operation is smoother.

[0033] The specific implementation process of the sliding bridge sealing door with spring assist of the present invention is as follows:

[0034] When opening the door leaf 1, lift the handle on the door leaf 1 by hand. Because the spring 14 has a certain elastic force, the door leaf 1 can be moved without too much force. The slideway 3 has an inclined slideway 8 and a flat slideway 9. In the inclined sliding stage, the door leaf 1 can be easily slid by lifting the handle by hand with the help of the elastic force of the spring 14. In the flat slideway 9 stage, the sliding shaft 5 rolls and slides in the slideway 3, with low friction and smooth movement. The spring 14 moves on the horizontal guide shaft 11.

[0035] When closing the door leaf 1, in the stage of the flat slideway 9, the handle is pushed, and the sliding shaft 5 rolls and slides in the slideway 3, with small friction and smooth movement. When the door leaf 1 moves to the inclined slideway 8, the door leaf 1 has a certain gravity, compresses the spring 14, and rotates the lock handle to lock the door leaf 1.

[0036] The spring-assisted sliding bridge sealing door of the present invention is installed at the end of the bridge and is a bridge maintenance sealing door. Because the spring 14 is used to assist the sliding on the slide 3, it is convenient to use, labor-saving, and highly safe, and has good sealing performance and good fire and moisture-proof effects.

[0037] The sealing door of the present invention has an innovative structure, strong practicability, is stable during the operation cycle, is safe and reliable in use, and has the advantages of high maintenance efficiency. It has a good market prospect and development space for the existing bridge sealing door technology.

[0038] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
