DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions of the present utility model will be further described in detail below with reference to the accompanying drawings:

[0023] Refer to Figure 1 - Figure 4As shown in the figure, the present utility model provides a technical solution: a safety protection door device for a construction elevator shaft, including an elevator main body 1, a protection door main body 2 is installed at the front end of the elevator main body 1, installation boxes 3 are installed on both sides of the elevator main body 1, two buckles 4 are slidably connected inside the installation boxes 3, elastic springs 5 are fixed on the opposite surfaces of the buckles 4, an installation plate 6 is installed at the rear end of the protection door main body 2, two card slots 7 are formed on the surface of the installation plate 6, sliding sleeves 8 are fixed at the top and bottom of the installation boxes 3, slots 9 are formed at the top and bottom of the installation boxes 3, sliding rods 10 are slidably connected inside the sliding sleeves 8 and the slots 9, and one end of the sliding rod 10 far away from the installation box 3 is fixedly connected with a push-pull plate 11. When installing the protection door main body 2 of the elevator, the staff must follow precise steps to ensure safety and stability. First, they focus on the positioning of the card slots 7, which is a key step in aligning with the corresponding buckles 4 on the elevator main body 1. Once the card slots 7 are accurately aligned with the buckles 4, the staff can perform the buckling operation, which will make the protection door main body 2 closely combine with the elevator main body 1. At this time, the elastic springs 5 begin to play their role, and the elastic force they store will be released after the buckling operation is completed, so that the buckles 4 can be firmly fixed in the card slots 7, ensuring the firmness and reliability of the protection door main body 2. However, even if the installation process is successfully completed, there may be a situation where the protection door main body 2 needs to be repaired during the use of the elevator. In this regard, the staff is fully prepared. They will operate the push-pull plate 11 to press it inward, and this action will cause the sliding rod 10 to move and push against the buckles 4 and the card slots 7, thus releasing their limit. Once the limit is released, the protection door main body 2 can be easily disassembled from its original position for necessary repair or replacement. This design of quick installation and disassembly takes into account the actual operation needs of the staff, greatly reducing their labor intensity and improving work efficiency.

[0024] Referring to Figure 3 As shown in the figure, in this implementation scheme: first sliding grooves 12 are formed on both sides inside the installation box 3, first sliding blocks 13 are fixed on both sides of the buckle 4, and the first sliding blocks 13 are slidably connected inside the first sliding grooves 12. Through the arrangement of the first sliding grooves 12 and the first sliding blocks 13, the buckle 4 can move more stably inside the installation box 3, thereby improving the stability of the buckle 4 buckling into the card slot 7.

[0025] Referring to Figure 4 As shown in the figure, in this implementation scheme: second sliding grooves 14 are formed at the front and rear ends inside the sliding sleeve 8, second sliding blocks 15 are fixed at the front and rear ends of the sliding rod 10, and the second sliding blocks 15 are slidably connected inside the second sliding grooves 14. Through the arrangement of the second sliding grooves 14 and the second sliding blocks 15, a stable limiting effect can be formed when the sliding rod 10 moves inside the sliding sleeve 8, preventing excessive pulling and causing detachment, which affects normal use.

[0026] Refer to Figure 4 As shown, in this implementation: A first return spring 16 is slidably connected to the surface of the sliding rod 10. One end of the first return spring 16 close to the push-pull plate 11 is fixedly connected to the push-pull plate 11, and the other end of the first return spring 16 away from the push-pull plate 11 is fixedly connected to the sliding sleeve 8. Through the setting of the first return spring 16, the push-pull plate 11 can be driven by the elastic force of the first return spring 16 to quickly reset the sliding rod 10 after the pressing is completed, facilitating the next use.

[0027] Refer to Figure 5 - Figure 7 As shown, in this implementation: Two moving rails 17 are installed at the rear end of the protection door main body 2. A traction block 18 is slidably connected inside the moving rail 17. The rear end of the traction block 18 is fixedly connected to a moving plate 19. A connecting plate 20 is installed at the rear end of the protection door main body 2. A threaded rod 21 is threadedly connected inside the connecting plate 20. A limiting groove 22 is provided on one side of the moving plate 19 close to the threaded rod 21. When a failure occurs in the protection door main body 2 and the staff cannot go out, the threaded rod 21 is screwed out of the limiting groove 22 to release the limit of the moving plate 19. At this time, the moving plate 19 is pulled upward to form a small door through which the staff can pass, so that the protection door main body 2 has an emergency exit when a failure occurs, improving the safety of the staff during work.

[0028] Refer to Figure 6 As shown, in this implementation: Third sliding grooves 23 are provided on both sides inside the moving rail 17. Third sliding blocks 24 are fixed on both sides of the traction block 18. The inside of the third sliding groove 23 is slidably connected to the third sliding block 24. Through the setting of the third sliding groove 23 and the third sliding block 24, a limiting effect can be formed during the pulling process of the moving plate 19, thereby improving the pulling stability of the moving plate 19.

[0029] Refer to Figure 6 As shown, in this implementation: A second return spring 25 is installed at the top of the traction block 18. The top of the second return spring 25 is fixedly connected to the inside of the moving rail 17. Through the setting of the second return spring 25, after the staff goes out from the moving plate 19, the elastic force of the second return spring 25 is released to drive the moving plate 19 to quickly bounce back, so as to achieve the quick reset of the moving plate 19 after use.

[0030] Working principle: When installing the main body 2 of the elevator protection door, the staff must follow precise steps to ensure safety and stability. First, they focus on the positioning of the card slot 7, which is a crucial step in aligning with the corresponding buckle 4 on the elevator main body 1. Once the card slot 7 is accurately aligned with the buckle 4, the staff can perform the buckling operation, which will tightly combine the main body 2 of the protection door with the elevator main body 1. At this time, the elastic springs 5 start to play their role. The elastic force they store will be released after the buckling operation is completed, enabling the buckle 4 to be firmly fixed in the card slot 7, ensuring the firmness and reliability of the main body 2 of the protection door. However, even if the installation process is successfully completed, there may be situations where the main body 2 of the protection door needs to be repaired during the use of the elevator. In this regard, the staff is fully prepared. They will operate the push-pull plate 11 to press it inward. This action will cause the sliding rod 10 to move and push against the buckle 4 and the card slot 7, thus releasing their limit. Once the limit is released, the main body 2 of the protection door can be easily disassembled from its original position for necessary repairs or replacements. This quick installation and disassembly design takes into account the actual operation needs of the staff, greatly reducing their labor intensity and improving work efficiency. Through the setting of the first chute 12 and the first slider 13, the buckle 4 can move more stably inside the installation box 3, thereby enhancing the stability of the buckle 4 when it is buckled into the card slot 7. Through the setting of the second chute 14 and the second slider 15, a stable limiting effect can be formed when the sliding rod 10 moves inside the sliding sleeve 8, preventing excessive pulling and causing detachment, which may affect normal use. Through the setting of the first return spring 16, after the pressing of the push-pull plate 11 is completed, the first return spring 16 can drive the sliding rod 10 to quickly reset due to its elastic force, facilitating the next use. When a failure of the main body 2 of the protection door causes the staff to be unable to get out, the threaded rod 21 is screwed out of the limit slot 22 to release the limit of the moving plate 19. At this time, when the moving plate 19 is pulled upward, a small door that allows the staff to pass through can be formed, so that the main body 2 of the protection door has an emergency exit when a failure occurs, enhancing the safety of the staff during work. Through the setting of the third chute 23 and the third slider 24, a limiting effect can be formed during the pulling process of the moving plate 19, thereby enhancing the pulling stability of the moving plate 19. Through the setting of the second return spring 25, after the staff goes out from the moving plate 19, the elastic force of the second return spring 25 is released to drive the moving plate 19 to quickly bounce back, thus achieving the quick reset of the moving plate 19 after use.
