Description

Technical Field

[0001] This utility model belongs to the field of door curtain technology, specifically relating to a novel contactless sliding door curtain. Background Technology

[0002] A door curtain is a curtain-like item used to cover doorways, isolate spaces, or serve a decorative purpose.

[0003] Existing sliding door curtains consist of two parts: a fixed curtain and a movable curtain. To avoid interference during opening and closing, the fixed and movable curtains need to be staggered. However, this staggering requires a sealing mechanism between them, which must fit snugly against both the fixed and movable curtains. This results in the movable curtain experiencing significant resistance from the sealing mechanism during movement, leading to higher energy requirements for movement and increased noise due to pressure on the sealing mechanism. Therefore, this application proposes a novel contactless sliding door curtain. Utility Model Content

[0004] The purpose of this utility model is to provide a novel contactless sliding door curtain to solve the problem of the fixed door curtain and the movable door curtain being staggered in the background art. However, if the two are staggered, a corresponding sealing mechanism needs to be set between them, and the sealing mechanism needs to be in contact with the fixed door curtain and the movable door curtain. This results in the movable door curtain being subject to more resistance from the sealing mechanism when it moves.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel contactless sliding door curtain, including a door frame, wherein a fixed door curtain and a movable door curtain are provided at the door frame, wherein two fixed door curtains are provided and are symmetrically distributed on two parallel sides of the door frame, and two movable door curtains are provided and are symmetrically distributed about the center line of the door frame. The movable door curtain is provided with a telescopic unit connected to the movable door curtain and a traveling unit connected to the telescopic unit for driving the telescopic unit to move in a direction parallel to the fixed door curtain. The door frame has at least two states, including an open state and a closed state. When the door frame is in the open state, the movable door curtain and the fixed door curtain are staggered front and back. When the door frame is in the closed state, the movable door curtain and the fixed door curtain are aligned left and right and front and back.

[0006] Preferably, the top and bottom of the movable door curtain are provided with detachable mounting frames.

[0007] Preferably, the direction in which the traveling unit moves the movable curtain is perpendicular to the direction in which the telescopic unit moves the movable curtain.

[0008] Preferably, the movable door curtain is provided with a slant plate, one end of which is movably connected to the movable door curtain, and the other end of which is movably connected to the traveling unit.

[0009] Preferably, one end of the telescopic unit is movably connected to the traveling unit, and the other end of the telescopic unit is movably connected to the inclined plate via a connecting shaft, the connecting shaft being located at the middle position of the inclined plate.

[0010] Preferably, the traveling unit includes a track distributed parallel to the fixed curtain, a slider that slides with the track, a threaded rod that is threadedly connected to the slider, and a power motor that is drivenly connected to the threaded rod.

[0011] Preferably, the power motor and the threaded rod are connected by a coupling.

[0012] Preferably, the traveling unit is provided with a guide rod connected to the movable door curtain and a guide seat that slides with the guide rod and is mounted on the traveling unit.

[0013] Preferably, an auxiliary plate is provided at the bottom of the door frame, and a gap is provided between the auxiliary plate and the fixed door curtain, the gap being greater than or equal to the thickness of the movable door curtain.

[0014] Preferably, the auxiliary plate has an angled structure on the side away from the door frame that is inclined away from the side of the fixed door curtain.

[0015] Beneficial effects: This utility model provides a novel contactless sliding door curtain. The telescopic unit moves the movable door curtain back and forth, allowing it to be staggered or aligned left and right. The traveling unit moves the movable door curtain left and right, aligning it left and right or separating it to open and close the door frame. This eliminates the need for manual opening and closing, saving effort. When the movable door curtain is closed, it is aligned left and right and back and forth, requiring only sealing gaskets at its edges. During the lateral movement of the traveling unit, the sealing gaskets do not contact the fixed door curtain, resulting in less resistance. The telescopic unit moves the movable door curtain a shorter distance, minimizing the relative displacement between the sealing gaskets and the fixed door curtain. This makes the entire movement more effortless and reduces noise caused by bending of the sealing gaskets. The movable door curtain fits tightly with the fixed door curtain and with the two movable door curtains, providing good door frame closure and effectively isolating internal and external temperatures.

It should be noted that there are two fixed door curtains 2, and the two fixed door curtains 2 are symmetrically distributed on two parallel sides of the door frame 1. There are two movable door curtains 3, and the two movable door curtains 3 are symmetrically distributed with respect to the center line of the door frame 1.

[0020] Since the movable door curtain 3 needs to be moved frequently, in order to avoid damage to the movable door curtain 3 due to frequent friction between the movable door curtain 3 and the door frame 1, detachable mounting frames 4 are provided at the top and bottom of the movable door curtain 3.

[0021] In order to enable the opening and closing of the door frame 1, a telescopic unit 6 is provided at the movable door curtain 3 to drive the movable door curtain 3 to move, and a traveling unit 8 is provided to drive the telescopic unit 6 to move in a direction parallel to the fixed door curtain 2. The direction in which the traveling unit 8 drives the movable door curtain 3 to move is perpendicular to the direction in which the telescopic unit 6 drives the movable door curtain 3 to move.

[0022] Through the cooperation of components such as telescopic unit 6 and inclined plate 5, the door frame 1 can have at least two states, including an open state and a closed state. When the door frame 1 is in the open state, the movable door curtain 3 and the fixed door curtain 2 are staggered front and back. When the door frame 1 is in the closed state, the movable door curtain 3 and the fixed door curtain 2 are aligned left and right and front and back.

The button is connected to the controller. After the button is pressed, the controller can make the traveling unit 8 and the telescopic unit 6 run according to the corresponding steps through the PLC program. Since there are few operation steps and the traveling mode is relatively simple, it is generally not necessary to set up corresponding sensors or other structures. Of course, for safety, corresponding sensors can also be set at the two ends of the telescopic unit 6 moving the movable door curtain 3, and at the point where the movable door curtain 3 reaches the open state of the door frame 1. The sensors can be proximity switches.

[0027] In order to make the movable curtain 3 move more smoothly back and forth, a guide rod 9 connected to the movable curtain 3 and a guide seat 10 slidably engaged with the guide rod 9 and installed on the travel unit 8 are provided at the travel unit 8.

[0028] It should be noted that an auxiliary plate 11 is provided at the bottom of the door frame 1. There is a gap between the auxiliary plate 11 and the fixed door curtain 2. The gap is greater than or equal to the thickness of the movable door curtain 3. The side of the auxiliary plate 11 away from the door frame 1 is provided with an angled structure that is inclined away from the side away from the fixed door curtain 2. When the movable door curtain 3 enters the gap, the two are in a gap fit relationship.

[0029] In summary, this utility model embodiment provides a novel contactless sliding door curtain. The telescopic unit 6 can drive the movable door curtain 3 to move back and forth, allowing the movable door curtain 3 to be staggered back and forth or aligned left and right. The traveling unit 8 can drive the movable door curtain 3 to move left and right, allowing the movable door curtain 3 to be aligned left and right or to separate left and right, realizing the opening and closing of the door frame 1. The door frame 1 can switch between open and closed states, eliminating the need for manual opening and closing of the door frame 1, thus saving effort. Furthermore, when the movable door curtain 3 is closed, it is aligned left and right and back and forth. The movable door curtain 3 fits tightly with the fixed door curtain 2 and the two movable door curtains 3, resulting in a better closing effect of the door frame 1 and the ability to insulate against internal and external temperatures.
