DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 5 The waterproof structure of the intelligent outer box of the elevator includes a frame 1 and an outer box body 4. A through groove 9 is opened on one side of the frame 1. The first frame 7 and the second frame 8 are fixed in the through groove 9 by bolts. A sealing strip 6 is bonded between the first frame 7 and the second frame 8. A first fixing block 3 is welded on both sides of the outer box body 4. An installation groove 2 is opened inside the first fixing block 3. The installation groove 2 is fixed to the frame 1 by bolts. A avoidance groove 11 is opened on one side of the outer box body 4. The third frame 10 is in close contact with the sealing strip 6. A circuit cover 12 is provided in the third frame 10, and the circuit cover 12 passes through the through slot 9. The third frame 10 on the back of the outer box body 4 is in close contact with the sealing strip 6, and then the bolts are fixed in the mounting slot 2 and fixed to the frame 1 to connect and fix the outer box body 4 to the frame 1. The outer box body 4 and the frame 1 are sealed by the cooperation of the first frame 7, the second frame 8, the sealing strip 6 and the third frame 10.

[0024] In the present invention, it should be noted that the outer walls of the outer box body 4 on both sides are bonded with guide rails 14, and a sliding cover 16 is slidably connected to the guide rails 14. The sliding cover 16 can block the outer box body 4, thereby protecting the outer box body 4. A spring piece 13 is welded inside the guide rail 14, and a slot 17 is provided at both ends of the sliding cover 16, and the spring piece 13 is snapped into the slot 17. The sliding cover 16 is pushed upward to move it along the guide rail 14 until the spring piece 13 is snapped into the slot 17, thereby fixing the position of the sliding cover 16. The inner walls on both sides of the sliding cover 16 are fixed with blocking blocks 18 by bolts, and the outer walls on both sides of the outer box body 4 are fixed with second fixing blocks 15 by bolts, and the second fixing blocks 15 are fixed with second fixing blocks 15 by bolts. The fixed block 15 is in contact with the blocking block 18. Through the cooperation of the second fixed block 15 and the blocking block 18, the sliding cover 16 moves upward to make the blocking block 18 move upward and contact the second fixed block 15, thereby limiting the height of the sliding cover 16 to prevent the sliding cover 16 from separating from the outer box body 4. The bottom inner wall of the sliding cover 16 is fixed with a scraper 19 by bolts. The scraper 19 is in contact with the side of the outer box body 4. The sliding cover 16 moves to make the scraper 19 scrape off dust and impurities on the outer box body 4. A top cover 5 is fixed to the outer wall of one side of the frame 1 by bolts, and the top cover 5 is located above the outer box body 4. The top cover 5 can block the outer box body 4 and the top of the sliding cover 16 to achieve a rainproof effect.

[0025] Working principle: The third frame 10 on the back of the outer box body 4 is in close contact with the sealing strip 6, and then the bolts are fixed to the mounting groove 2 and the frame 1 to connect and fix the outer box body 4 and the frame 1. The outer box body 4 and the frame 1 are sealed by the cooperation of the first frame 7, the second frame 8, the sealing strip 6 and the third frame 10. When the outer box body 4 needs to be protected, push the sliding cover 16 downward to move it downward along the guide rail 14 until it completely covers the outer box body 4.

[0026] Furthermore, the terms "installed," "disposed," "connected," and "socketed" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.
