[0024] 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.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a protective device for indoor building decoration, including a plate 1, with an inner cavity 2 in the middle of the plate 1. A first rotating shaft 3 is rotatably mounted inside the plate 1 via bearings. A first lead screw 4 is installed inside the first rotating shaft 3. A movable plate 5 is fixed to the end of the first lead screw 4 through the interior of the first rotating shaft 3. A rubber anti-slip plate 6 is fixed to one side of the movable plate 5. A first bevel gear 7 is fixed to the end of the first rotating shaft 3 inside the inner cavity 2. A second... The second shaft 8 has a second bevel gear 9 fixed inside the inner cavity 2 at one end. The side of the second bevel gear 9 meshes with the side of the first bevel gear 7. The other end of the second shaft 8 has a mating groove 10 inside. A mating rod 11 is installed inside the mating groove 10. A first handle 12 is fixed outside the second shaft 8 at the end of the mating rod 11. The plate 1 has a sliding groove 19 inside. A sliding rod 20 is slidably installed inside the sliding groove 19. The end of the sliding rod 20 is fixedly connected to one side of the movable plate 5.

[0026] The top of the slide groove 19 is provided with an anti-detachment groove 21, and an anti-detachment rod 22 is slidably installed inside the anti-detachment groove 21. The end of the anti-detachment rod 22 is fixedly connected to one side of the top of the slide rod 20. Under the action of the anti-detachment groove 21 and the anti-detachment rod 22, the slide rod 20 and the slide groove 19 are guaranteed not to separate.

[0027] A full gear 13 is fixed to the outer wall of the second rotating shaft 8 outside the plate 1. A fixing plate 14 is fixed to the outer wall of the plate 1 above the full gear 13. A second lead screw 15 passes through the inside of the fixing plate 14. A toothed plate 16 is rotatably mounted on the lower end of the second lead screw 15 through a bearing. The bottom of the toothed plate 16 is engaged with the top of the full gear 13. A guide rod 18 is fixed to one side of the top of the toothed plate 16. The upper end of the guide rod 18 passes through the inside of the fixing plate 14. A second handle 17 is fixed to the upper end of the second lead screw 15. The fixing plate 14 and the second lead screw 15 are threaded together. The guide rod 18 and the fixing plate 14 are slidably connected. This ensures that the second rotating shaft 8 will not rotate when the bottom of the toothed plate 16 is engaged with the top of the full gear 13. This ensures that the distance between the two movable plates 5 after they move will not move, so that the two movable plates 5 can be fixed to the wall of the corridor.

[0028] The first rotating shaft 3, the first lead screw 4, the movable plate 5, the rubber anti-slip plate 6, and the first bevel gear 7 are all symmetrically distributed in twos about the central axis of the second bevel gear 9. The threads on the two first lead screws 4 are set in the same direction, and the first rotating shaft 3 and the first lead screw 4 are threadedly connected, which ensures that when the second bevel gear 9 rotates forward or reverses, the two movable plates 5 can move closer to each other or move further away from each other.

[0029] The docking groove 10 and the docking rod 11 are engaged and connected. Both the docking groove 10 and the docking rod 11 are designed as regular hexagonal structures when viewed from the front. This ensures that when the docking rod 11 rotates, it can drive the second rotating shaft 8 to rotate through the docking groove 10. This also ensures that after the docking rod 11 and the first handle 12 are removed, it is difficult for outsiders to rotate the second rotating shaft 8.

[0030] Working principle: When using this indoor building decoration protective device, the user first picks up the first handle 12, then inserts the connecting rod 11 on the first handle 12 into the connecting groove 10, and then rotates the first handle 12. The first handle 12 drives the second rotating shaft 8 and the second bevel gear 9 to rotate through the connecting groove 10 and the connecting rod 11. Since the second bevel gear 9 and the first bevel gear 7 are meshed, the second bevel gear 9 drives the two first bevel gears 7 to rotate in opposite directions. The two first bevel gears 7 cause the two first rotating shafts 3 to rotate in opposite directions. Since the threads on the two first lead screws 4 are set in the same direction, and the first rotating shafts 3 and the first lead screws 4 are threadedly connected, the two first lead screws 4 push the two movable plates 5 to move in opposite directions. At the same time, the movable plates 5 drive the sliding rod 20 in the sliding groove. The device moves internally until the rubber anti-slip pads 6 on the two movable plates 5 are in close contact with the sides of the corridor, thus fixing the protective device to the wall. Then, the second handle 17 is rotated, which drives the second lead screw 15 to rotate. Since the fixed plate 14 and the second lead screw 15 are threadedly connected, and the guide rod 18 and the fixed plate 14 are slidably connected, the second lead screw 15 drives the toothed plate 16 to move downward, so that the bottom of the toothed plate 16 engages with the top of the full gear 13, thus fixing the second rotating shaft 8 and preventing it from rotating. This also fixes the positions of the two movable plates 5 and the two rubber anti-slip pads 6, improving the stability of the protective device fixed to the corridor. Finally, the first handle 12 and the docking rod 11 are removed from the docking groove 10 to prevent outsiders from using the first handle 12 and the docking rod 11 to rotate the second rotating shaft 8.

[0031] 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.
