Description

Technical Field

[0001] This utility model relates to the field of anti-collision strip technology, specifically to an anti-rebound sliding door anti-collision strip. Background Technology

[0002] Sliding doors are widely used in homes and offices due to their space-saving and aesthetically pleasing advantages. However, existing sliding door anti-collision strips generally suffer from poor anti-rebound performance. Traditional anti-collision strips are mainly made of elastic materials, which only provide simple cushioning and cannot effectively prevent the sliding door from rebounding. When the sliding door hits the anti-collision strip, due to inertia, the door is prone to rebound, making it impossible to close completely and affecting the user experience. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides an anti-rebound sliding door anti-collision strip that can clamp the sliding door when it is closed, using friction to slow it down and prevent the sliding door from rebounding.

[0004] This utility model discloses an anti-rebound sliding door anti-collision strip, including a base plate. The base plate has symmetrically arranged clamping structures on both sides. Each clamping structure includes a side plate, a first elastic piece, a connecting plate, and a connector. The side plates are arranged on both sides of the base plate and are perpendicular to each other. A first elastic piece is arranged along the length of the side plate on the side closest to the base plate, protruding towards the side away from the side plate. One side of the first elastic piece is sealed to the side of the side plate away from the base plate. A connecting plate is arranged along the length of the first elastic piece on the other side, sealingly connecting to the first elastic piece. The connecting plate is fixedly connected to the side plate via a connector. A second elastic piece is arranged between the two clamping structures, protruding towards the side away from the base plate. Both sides of the second elastic piece are sealed to the corresponding connecting plates on both sides. The base plate, side plate, first elastic piece, connecting plate, and second elastic piece form a closed annular structure. Sealing elements are provided at both ends of the annular structure for sealing.

[0005] The principle of the above technical solution is as follows: the base plate is fixed on the door frame. When the sliding door hits the anti-collision strip, the first elastic sheet first contacts the sliding door and decelerates the sliding door through friction. When the sliding door hits the second elastic sheet, it deforms under force, further buffering the impact. At the same time, the air pressure inside the annular structure increases after the second elastic sheet is compressed, which causes the first elastic sheet in the clamping structure on both sides to bulge further, thereby further clamping the sliding door and using friction to further decelerate the sliding door. When the sliding door completes deceleration, the clamping force of the first elastic sheet on the sliding door reaches its maximum, thus using the friction of the first elastic sheet on the sliding door to prevent it from rebounding.

[0006] Preferably, the connector is strip-shaped, and its length is shorter than that of the side plate. One side of the connector is fixed to the side plate, and the other side of the connector is fixed to the connecting plate. This design can effectively fix the connecting plate to the side plate without affecting the flow of internal airflow.

[0007] The anti-rebound sliding door anti-collision strip obtained by this utility model has the following beneficial effects: when the sliding door hits the anti-collision strip, the first elastic piece first contacts the sliding door and initially decelerates the sliding door through friction; subsequently, the sliding door hits the second elastic piece, causing it to deform under force, further buffering the impact force. At the same time, after the second elastic piece is compressed, the air pressure inside the annular structure increases, pushing the first elastic piece in the clamping structure on both sides to bulge further, thereby enhancing the clamping force on the sliding door, and further decelerating and preventing the sliding door from rebounding by using friction.

[0012] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0013] Example 1:

[0014] like Figure 1 , 2As shown in Figures 3 and 4, this utility model discloses an anti-rebound sliding door anti-collision strip, including a base plate 7. Clamping structures are symmetrically arranged on both sides of the base plate 7. Each clamping structure includes a side plate 1, a first elastic piece 4, a connecting plate 5, and a connector 6. The side plates 1 are arranged on both sides of the base plate 7 and are perpendicular to each other. A first elastic piece 4 is arranged along the length of the side plate 1 on the side closest to the base plate 7. The first elastic piece 4 protrudes towards the side away from the side plate 1. One side of the first elastic piece 4 is sealed to the side of the side plate 1 away from the base plate 7. A connecting plate 5 is arranged along the length of the first elastic piece 4 on the other side. The connection between the connecting plate 5 and the first elastic piece 4 is sealed. A connecting piece 6 is provided between the connecting plate 5 and the side plate 1. The connecting piece 6 is strip-shaped and its length is shorter than that of the side plate 1. One side of the connecting piece 6 is fixed to the side plate 1, and the other side of the connecting piece 6 is fixed to the connecting plate 5. A second elastic piece 2 is provided between the two clamping structures. The second elastic piece 2 protrudes towards the side away from the bottom plate 7. Both sides of the second elastic piece 2 are sealed to the corresponding connecting plates 5 on both sides. The bottom plate 7, the side plate 1, the first elastic piece 4, the connecting plate 5 and the second elastic piece 2 form a closed ring structure. Sealing pieces 3 are provided at both ends of the ring structure for sealing.

[0015] The principle of the above technical solution is as follows: the base plate 7 is fixed on the door frame. When the sliding door hits the anti-collision strip, the first elastic piece 4 contacts the sliding door and decelerates the sliding door through friction. When the sliding door hits the second elastic piece 2, it deforms under force, further buffering the impact. At the same time, the air pressure inside the annular structure increases after the second elastic piece 2 is compressed, which causes the first elastic piece 4 in the clamping structure on both sides to bulge further, thereby further clamping the sliding door and using friction to further decelerate the sliding door. When the sliding door completes deceleration, the clamping force of the first elastic piece 4 on the sliding door reaches its maximum, thus using the friction of the first elastic piece 4 on the sliding door to prevent it from rebounding.
