AI Technical Summary
The open design of existing bed frames allows external dust to enter and accumulate inside the frame, increasing the difficulty of cleaning. Furthermore, the dust cover is prone to wear and tear, affecting its service life and health.
A retractable dust cover is installed at the opening of the bed frame. The dust cover changes its size according to the size of the opening to ensure a sealing effect, and its size decreases when it is closed to facilitate folding and extend its service life.
It effectively prevents dust accumulation, reduces cleaning workload, extends the service life of the dust cover, and improves the user experience.

Abstract
Claims
1. A bed frame with a dustproof cover, comprising a frame body (1) and a support plate assembly disposed on the frame body (1), the support plate assembly comprising a fixed part fixedly connected to the frame body (1) and a movable part movable relative to the fixed part, characterized in that, A retractable dustproof cover is connected between the movable part and the corresponding edge of the frame (1). The dustproof cover can switch between a retracted state and an unfolded state. When the dustproof cover is in the unfolded state, it can be stretched and deformed in conjunction with the movable part and completely cover the opening formed between the movable part and the corresponding edge of the frame (1).
2. The bedstead with a dust cover preventing shield according to claim 1, wherein, The top and bottom edges of the dust cover are fixed to the corresponding edges of the movable part and the frame (1), respectively. When the dust cover is switched to the unfolded state, it can be stretched out by pulling and completely cover the opening.
3. The bed frame with a dust cover according to claim 2, characterized in that, The frame (1) includes a surrounding panel (4), and the bottom edge of the dust cover is bent upward to form a downward flange (2). The downward flange (2) is attached to the inner wall of the surrounding panel (4) to limit the displacement of the bottom edge of the dust cover.
4. The bed frame with a dust cover according to claim 3, characterized in that, The bottom edge of the enclosure (4) is fitted to the ground.
5. The bed frame with a dust cover according to claim 2, wherein, The top edge of the dustproof cover is bent inward to form an upturned edge (3). The upturned edge (3) is attached to the bottom surface of the corresponding edge of the movable part and fixed by fasteners to eliminate the gap between the top edge of the dustproof cover and the movable part.
6. The bedstead with a dust cover according to any one of claims 1-5, characterized in that, The fixed part consists of a lumbar support plate (5) and a hip support plate (6) placed in front and behind. The movable part includes a back support plate (7) that swings and connects to the front edge of the lumbar support plate (5), a thigh plate (8) that swings and connects to the rear edge of the hip support plate (6), and a calf plate (9) that swings and connects to the rear edge of the thigh plate (8). The dust cover includes a front cover (10) that cooperates with the back support plate (7) and a rear cover (11) that cooperates with the thigh plate (8) and the calf plate (9).
7. The bed frame with a dust cover according to claim 6, characterized in that, The front cover (10) is an integral structure, including a square front part (12) and a triangular front side part (13) disposed on both sides of the front part (12). The front part (12) spans between the front edge of the bed frame and the front edge of the back support plate (7). The front side part (13) spans between the front side edge of the bed frame and the side edge of the back support plate (7). The back support plate (7) swings around the front edge of the waist support plate (5) and drives the front cover (10) to block the corresponding opening.
8. The bed frame with a dust cover according to claim 7, characterized in that, The rear cover (11) is an integral structure, including a square rear part (15) and rear side parts (14) on both sides of the rear part (15). The rear part (15) spans between the rear edge of the lower leg plate (9) and the rear edge of the bed frame. The rear side parts (14) span between the side edges of the thigh plate (8) and the lower leg plate (9) and the rear side edge of the bed frame. The thigh plate (8) swings with the rear edge of the buttock support plate (6) as the center. The lower leg plate (9) swings with the rear edge of the thigh plate (8) as the center, so as to drive the rear cover (11) to block the corresponding opening.
9. The bed frame with a dust cover according to claim 8, characterized in that, The top edge of the rear side (14) includes a front straight segment (16) and a rear straight segment (17) that are placed front and rear respectively. The front straight segment (16) is attached to and fixed to the side edge of the thigh plate (8) and moves in conjunction with it. The rear straight segment (17) is attached to and fixed to the side edge of the calf plate (9) and moves in conjunction with it.
10. The bed frame with a dust cover according to claim 9, wherein, The front straight section (16) is low in the front and high in the back, and the front end of the front straight section (16) is set close to the rear edge of the buttock support plate (6) to cooperate with the swing of the thigh plate (8); or, the rear end of the rear straight section (17) is flush with the top edge of the rear part (15).
