Description

Technical Field

[0001] This utility model relates to the field of security door technology, specifically a double-slanted security door designed to prevent bumps and injuries. Background Technology

[0002] Existing automatic sensor doors have the following main drawbacks in design and function:

[0003] 1. High risk of collision: Traditional automatic doors often have right-angled edges, which can easily cause pedestrians to bump into them during rapid opening and closing, especially in crowded places (such as hospitals and shopping malls), posing a significant safety hazard.

[0004] 2. Narrow exits: Existing automatic doors have limited opening angles and exit areas. Especially when passing at an angle, pedestrians are prone to rubbing against the door or door frame, affecting passage efficiency and failing to meet the needs of rapid evacuation in emergency situations.

[0005] 3. Inconvenient emergency passage: Most automatic doors rely entirely on electric power. Once the power is cut off or the system malfunctions, the door is difficult to open manually, which does not meet the safety requirements for fire evacuation and may delay escape or rescue in emergency situations.

[0006] Therefore, we propose a double-slanted safety door to prevent collisions and injuries. Utility Model Content

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a double-slanted safety door to prevent bumps and injuries, which has the following beneficial effects:

[0020] 1. This is a double-sloped safety door designed to prevent collisions and injuries. The door body is provided with a second sloping edge, and the door frame post is provided with a first sloping edge. The two form a smooth transition structure, which increases the exit area and significantly reduces the probability of collision when pedestrians pass at an angle. The edges of the door body adopt a rounded chamfer design to further avoid collisions caused by right-angled edges and improve passage safety.

[0021] 2. This type of double-sloped safety door is designed to prevent collisions and injuries. The second sloping side is fitted with a buffer rubber pad, which can absorb the impact force when the door closes, reduce collision noise, and protect the door and door frame posts, thus extending their service life. The worm gear is made of nylon composite material and is used in conjunction with a double-headed worm gear drive, which significantly reduces operating noise and is suitable for places with high requirements for quiet operation.

[0022] 3. This type of double-slanted safety door prevents collisions and injuries. The lead angle of the worm gear is greater than the friction angle, which makes the transmission system reversible. In the event of a power outage or emergency, pedestrians can manually push the door to drive the worm gear to reverse and open the door, thus meeting the requirements for fire evacuation.

[0023] 4. This double-sloping safety door, designed to prevent collisions and injuries, is driven by a worm gear mechanism. It has a large transmission ratio and runs smoothly, avoiding the vibration and noise problems associated with gear or belt drives. Attached Figure Description

The outer surfaces of one end of each set of rotating shafts 10 are fixedly connected to the outer surface of one end of the output shaft of the dual-output shaft motor 9 via the couplings. A worm gear 11 is fixedly installed on the outer wall of the end of the rotating shaft 10 away from the dual-output shaft motor 9. A worm wheel 12 is located on one side of the outer surface of the worm gear 11 and is fixedly installed on the outer wall of the upper part of the driven shaft 13. The lower outer surface of the driven shaft 13 is fixedly connected to the upper outer surface of the door body 3 near the door frame post 2.
