Description

Technical Field

[0001] This utility model belongs to the field of automatic doors, and specifically relates to a sliding drive folding automatic door. Background Technology

[0002] Automatic doors are doors that open and close automatically through sensors or control systems. They are mainly used in public places to improve passage efficiency and convenience. Traditional automatic doors mainly include swing-type and rotary-type doors. Traditional automatic doors have obvious disadvantages in terms of space occupation, mainly because they require a large range of motion when opening, which can easily obstruct pedestrian flow or occupy usable area. The disadvantage of traditional automatic doors in terms of space occupation mainly stems from their movement mode. Swing-type automatic doors rotate outward or inward around the door hinge when opening, requiring a large fan-shaped area for the door leaf to swing. If installed in narrow passages or densely populated areas, they may obstruct pedestrian passage or collide with surrounding facilities. Therefore, we hope to design a sliding-driven folding automatic door to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sliding drive folding automatic door to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a sliding drive folding automatic door, comprising: a door frame, wherein the upper end of the door frame is provided with a sliding mechanism for sliding the door leaf, and the sliding mechanism is provided with a folding mechanism for folding the door leaf;

[0005] The translation mechanism includes a mounting plate, which is fixedly connected to the front side of the door frame. A drive motor is provided on the mounting plate, and a pulley is fixedly connected to the output shaft of the drive motor. A pulley is also provided on the upper left side of the door frame, and a transmission belt is fixedly sleeved on the outer side of both pulleys.

[0006] The upper end of the door frame is fixedly connected to a slide rail, and two sets of sliders are slidably sleeved on the outer side of the slide rail. Each set of sliders is fixedly connected to a support block. By setting a translation mechanism, the door leaf slides horizontally along the slide rail, reducing the radius occupied by door leaf one and door leaf two when they are opened front and back.

[0007] In a preferred embodiment, the upper surface of the support block on the right is provided with anti-slip teeth that engage with the transmission belt. A fixing block for holding the transmission belt is connected to the support block by screws. The fixing block is used to fix the transmission belt to the support block, thereby driving the slider to move.

[0008] In a preferred embodiment, the upper surface of the support block on the left is in contact with the transmission belt, and the lower side of the fixing block on the left is also fixedly connected with anti-slip teeth. After the anti-slip teeth on the lower side of the fixing block on the left are engaged with the transmission belt, they are fixedly connected to the support block by screws.

[0009] In a preferred embodiment, the folding mechanism includes a first door leaf and a second door leaf, which are hinged together. By setting up the folding mechanism, the horizontal space occupied by the folding door after it is opened is reduced.

[0010] In a preferred embodiment, the upper end of the door leaf is fitted with a fixed shaft via a bearing, the fixed shaft is fixedly connected to the slide rail, and the lower end of the door leaf is hinged to the door frame.

[0011] In a preferred embodiment, the upper end of the second door leaf is fitted with a connecting shaft via a bearing, and the other end of the connecting shaft is fixedly connected to the slider.

[0013] In a preferred embodiment, the lower end of the second door leaf is fixedly connected to a second slider for improving the stability of opening and closing the lower end of the door.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. By setting up a translation mechanism, the transmission belt drives the slider to move on the slide rail through the support block. The slider further drives the second door leaf to move, so as to realize the horizontal sliding displacement of the second door leaf along the slide rail, thereby reducing the space radius occupied by the first and second door leaves due to opening in the front and rear, and ultimately reducing the occupation of the fan-shaped area when the door is opened.

[0016] 2. By setting up a folding mechanism, the second door leaf folds together with the first door leaf, reducing the horizontal space occupied by the door leaf after it is opened. Attached Figure Description

[0026] Please see Figures 1-3 As the first embodiment of this utility model:

[0027] A sliding-driven folding automatic door includes: a door frame 1, a sliding mechanism 2 for sliding the door leaf is provided at the upper end of the door frame 1, and a folding mechanism 3 for folding the door leaf is provided on the sliding mechanism 2.

[0028] The translation mechanism 2 includes a mounting plate 21, which is fixedly connected to the front side of the door frame 1. A drive motor 22 is provided on the mounting plate 21, and a pulley 23 is fixedly connected to the output shaft of the drive motor 22. A pulley 23 is also provided on the upper left side of the door frame 1. A transmission belt 24 is fixedly sleeved on the outer side of both pulleys 23.

[0029] A slide rail 25 is fixedly connected to the upper end of the door frame 1. Two sets of sliders 26 are slidably sleeved on the outer side of the slide rail 25. Support blocks 27 are fixedly connected to both sets of sliders 26. By setting the translation mechanism 2, the door leaf slides horizontally along the slide rail 25, reducing the radius occupied by the door leaf 31 and the door leaf 32 when they are opened in the front and back.

[0030] The upper surface of the right support block 27 is provided with anti-slip teeth 28, which are engaged with the transmission belt 24. A fixing block 29 for holding the transmission belt 24 is connected to the support block 27 by screws. The transmission belt 24 is fixedly connected to the support block 27 by the fixing block 29, thereby driving the slider 26 to move.

[0031] The upper surface of the left support block 27 is in contact with the transmission belt 24, and the lower side of the left fixing block 29 is also fixedly connected with anti-slip teeth 28.
