[0025] See also Figure 1-5The utility model provides a technical solution: a double-layer grille ventilation door, comprising a door frame 1, a moving assembly 2 for driving the grille ventilation door to move is provided at the top of the door frame 1, the moving assembly 2 is mounted on the wall through fasteners, the bottom end of the door frame 1 is provided with a limiting assembly 3 for improving the stability of the grille ventilation door when it moves, anti-collision blocks 4 are provided on both sides of the door frame 1, a steel plate 5 is fixedly welded to the bottom end of the inner cavity of the door frame 1, a grille plate 6 is provided at the top end of the steel plate 5, the other end of the grille plate 6 is fixedly connected to the inner side of the door frame 1, two groups of grille plates 6 are provided, and stainless steel protective nets 7 are provided on both sides of the door frame 1, one end of the stainless steel protective net 7 is fixedly connected to the top end of the steel plate 5, and one end of the stainless steel protective net 7 is fixedly connected to the inner wall of the door frame 1;

[0026] When opening the grille door, start the moving component 2 to drive the grille door to move. During movement, the limit component 3 at the bottom is used to limit the front and rear directions of the grille door to avoid shaking back and forth during movement. The stainless steel protective net 7 can be set to protect the grille to prevent damage caused by external collisions. The setting of two groups of grilles increases the protective effect of the grille ventilation door, thereby improving the safety protection effect of the grille ventilation door on the facility and increasing the service life of the grille ventilation door.

[0027] The moving component 2 includes an electric slide rail 21, which is located at the top of the door frame 1. The electric slide rail 21 is fixed to the wall by expansion bolts. A pulley 22 is provided on the electric slide rail 21. The bottom end of the pulley 22 is fixedly connected to a connecting seat 23. The bottom end of the connecting seat 23 is fixedly connected to the top of the door frame 1. Starting the electric slide rail 21 drives the pulley 22 to move, so that the pulley 22 drives the door frame 1 to move through the connecting seat 23, thereby realizing the opening or closing operation of the double-layer grille ventilation door.

[0028] The limiting assembly 3 includes a support seat 31, which is arranged at the bottom end of the door frame 1. A cavity is opened inside the support seat 31, and the support seat 31 is provided with an anti-collision plate 32. The other end of the support seat 31 is provided with an anti-collision strip 33. The bottom end of the double-layer grille ventilation door is limited by the cooperation of the anti-collision plate 32 and the anti-collision strip 33 on the support seat 31, thereby preventing the double-layer grille ventilation door from shaking back and forth when moving, thereby improving the stability of the double-layer grille ventilation door when moving.

[0029] The anti-collision strip 33 is located in the inner cavity of the support seat 31. The surface of the anti-collision strip 33 is provided with anti-collision bumps, and there are five groups of anti-collision bumps. Through the setting of the anti-collision bumps, when the bottom end of the door frame 1 contacts the anti-collision bumps, the contact force is dispersed and transmitted through the five groups of anti-collision bumps, thereby improving the protective effect of the anti-collision bumps on the bottom end of the door frame 1.

[0030] The bottom end of the anti-collision plate 32 is bolted with a support block 8, which is located in the inner cavity of the support seat 31. The support block 8 is in an I-shape. Through the cooperation between the support block 8 and the anti-collision plate 32, the anti-collision plate 32 can be easily plugged in, which facilitates the later maintenance of the anti-collision plate 32.

[0031] Limiting frames 9 are provided on the upper and lower sides of the door frame 1. One group of limiting frames 9 is fixed to the wall by expansion bolts, and the other group of limiting frames 9 is installed in the inner cavity of the support seat 31. Through the setting of the limiting frames 9, the upper and lower ends of the door frame 1 are limited again, thereby improving the stability of the door frame 1 during movement.

[0032] The surface of the wall is bolted with a mounting plate 10 by expansion bolts, and the inner wall of the mounting plate 10 is bolted with a limiting block 11. The height of the mounting plate 10 is equal to the height of the anti-collision block 4. Through the cooperation of the mounting plate 10 and the limiting block 11, the distance between the door frame 1 and the wall is limited to avoid collision between the double-layer grille ventilation door and the wall when moving.

[0033] During specific use: when the double-layer grille ventilation door moves, the electric slide rail 21 is started to drive the pulley 22 to move, so that the pulley 22 drives the door frame 1 to move through the connecting seat 23, thereby realizing the opening or closing operation of the double-layer grille ventilation door. When moving, the bottom end of the door frame 1 is limited by the anti-collision plate 32 and the anti-collision strip 33 on the bottom end support seat 31, and the upper and lower ends of the door frame 1 are limited by two sets of pulleys 22, thereby improving the stability of the double-layer grille ventilation door during movement. Through the setting of the stainless steel protective net 7, the grille plate 6 in the double-layer grille ventilation door is protected to prevent the grille plate 6 from colliding with the outside world. Through the setting of the two sets of grille plates 6, when one set of grille plates 6 is damaged, the other set of grille plates 6 can still be used in combination, thereby improving the safety protection effect of the grille ventilation door on the facility and improving the service life of the grille ventilation door.
