Description

Technical Field

[0001] The utility model belongs to the technical field of safety doors, and in particular relates to a visual anti-collision safety door for large-scale factories. Background Art

[0002] Large factories often have large entrances, with numerous people, vehicles, and equipment entering and exiting. Therefore, conventional doors are larger than conventional doors. Currently, commonly used factory doors are bifold, which is convenient to open, but they occupy a large area inside the factory or at the entrance, making them prone to collisions with equipment or personnel inside, causing damage to them or posing a safety threat. Furthermore, conventional doors offer limited visibility outside, making them difficult to open in a timely manner when vehicles or personnel need to pass through, making them inconvenient. Utility Model Content

[0003] In response to the problems existing in the prior art, the utility model provides a visual anti-collision safety door for large-scale factories, which specifically includes the following contents:

[0004] A visual anti-collision safety door for a large factory building includes two telescopic door panels, multiple elastic anti-collision devices, and multiple rollers. The two telescopic door panels are respectively arranged on opposite sides of a door frame. The telescopic door panels include a first door panel, a second door panel, and a third door panel arranged in parallel in sequence. Each door panel includes a front face and a back face. The back face of the first door panel is rotatably connected to the door frame via multiple hinges. In this way, the door retracts inward when opened and will not hit people or objects outside the door.

[0005] The front of the second door panel is rotatably connected to the front of the first door panel via multiple hinges; the front of the third door panel is rotatably connected to the front of the second door panel via multiple hinges; the sum of the widths of the first door panel and the third door panel is not greater than the width of the second door panel; the purpose of this arrangement is to enable the second door panel to fold outward and the third door panel to fold inward when the door is opened. At this time, the first door panel and the third door panel are just folded and stored on the same side of the second door panel. The three door panels overlap and shrink together, reducing the horizontal and vertical space occupied when the door is opened, avoiding collisions with people or objects, and being safer and more reliable.

[0006] An elastic anti-collision device is provided on the side of each door panel facing its rotation direction; because the door panels are easily hit by other door panels or people or objects during rotation when they are rotated and folded along the hinges, an elastic anti-collision device is provided on the side facing its rotation direction to reduce damage and safety hazards caused by collisions.

[0007] Each door panel is equipped with rollers at the bottom. When the door needs to be opened, the door panels are pushed to the sides between the two telescopic door panels. The rollers on the two door panels then roll to the sides, driving the door panels to rotate along the hinges and then fold together to open the door. The rollers make door opening more labor-saving.

[0008] The second door panel is provided with an anti-collision perspective window, which enables people inside or outside the door to grasp the situation on the other side, prevents collision when opening the door, and improves safety.

[0009] Furthermore, the elastic anti-collision device is an elastic anti-collision block, an elastic anti-collision strip, or an elastic anti-collision layer covering the door panel. Furthermore, the elastic anti-collision block, elastic anti-collision strip, or elastic anti-collision layer is made of elastic cushioning material. Because door panels rotate and fold along hinges, they are prone to colliding with other door panels or people or objects during rotation. Therefore, using elastic cushioning material to form an elastic anti-collision device on the side facing the rotation can reduce damage and safety hazards caused by collisions.

[0010] Furthermore, the distance between the bottom of the anti-collision window and the bottom of the second door panel is 0.8-1.0m, and the distance between the top of the anti-collision window and the bottom of the anti-collision window is 0.3-0.5m. Furthermore, the width of the anti-collision window is 0.3-0.5m. The height and width are designed based on the height and sight angle of an adult, making it easier to observe what is happening outside the door within a certain range.

[0011] Furthermore, in order to improve the strength and durability of the door, the telescopic door panel is generally made of metal material, and can also be made of wood material when necessary.

[0012] Beneficial effects of the utility model:

[0013] (1) The visual anti-collision safety door for large factories disclosed in the present invention includes two retractable door panels, multiple elastic anti-collision devices, and multiple rollers.

The front of the second door panel is rotatably connected to the front of the first door panel through multiple hinges; the front of the third door panel is rotatably connected to the front of the second door panel through multiple hinges; the sum of the widths of the first door panel and the third door panel is not greater than the width of the second door panel; the purpose of this arrangement is to make the second door panel fold outward and the third door panel fold inward when the door is opened. At this time, the first door panel and the third door panel are just folded and stored on the same side of the second door panel. The three door panels overlap and shrink together, reducing the horizontal and vertical space occupied when the door is opened, avoiding collisions with people or objects, and being safer and more reliable.

[0014] (2) Each door panel of the visual anti-collision safety door for large factories disclosed by the utility model is provided with an elastic anti-collision device on one side facing the direction of rotation, which can reduce the damage and safety hazards caused by collisions.
