Description

Technical Field

[0001] The utility model relates to the technical field of traffic safety facilities, in particular to a double-layer protective shielding door structure. Background Art

[0002] BRT bus stops are usually equipped with a safety screen door on one side to separate passengers from road vehicles before the bus arrives at the stop, thus preventing passengers from mistakenly entering the bus area and causing safety accidents.

[0003] In the prior art, the door body of a safety shielding door is usually an integrated frame structure, which is usually a single-layer structure. If the glass in the frame is accidentally broken during use, the protective effect of the shielding door will be greatly reduced. At the same time, it is more cumbersome to replace the glass in the later stage. The safety door is usually an electronic lock, and the shielding door must be frequently opened and closed during each movement. Failure of the electronic lock will cause the safety shielding door to lose its effect. For this reason, we propose a double-layer protective shielding door structure. Utility Model Content

[0027] The movement of the sliding mounting strip 34 is limited by the sliding groove 2 38, and the tempered glass is installed and fixed by the two tempered glass mounting grooves 33 in the sliding door mounting frame 31. The tempered glass is installed from the upper end of the sliding door mounting frame 31. After installation, the sliding door mounting frame 31 is fixed to the sliding mounting strip 34 by the fixing bolts 35, and the sliding wheel 32 under the sliding door mounting frame 31 reduces the friction of the sliding door mounting frame 31 when moving along the sliding groove 1 37, thereby facilitating installation and movement.

[0028] The sliding door unit 3 also includes an infrared emitter 36 and an infrared receiver 39. Two tempered glass mounting slots 33 are defined on the inner side of the sliding door mounting frame 31. The infrared emitter 36 is fixedly connected to the inner right end of the door frame 1, while the infrared receiver 39 is fixedly connected to the right end of the sliding door mounting frame 31. The infrared emitter 36, infrared receiver 39, and motor 43 work together to activate the motor 43 when a person passes by while the sliding door mounting frame 31 is moving. This prevents injury to pedestrians and provides a safety feature.

Two tempered glass mounting grooves 33 within a sliding door mounting frame 31 are used to install and secure the tempered glass. The tempered glass is installed from the upper end of the sliding door mounting frame 31. After installation, the sliding door mounting frame 31 is secured to the sliding mounting bar 34 using fixing bolts 35. Sliding wheels 32 below the sliding door mounting frame 31 reduce friction during movement along the first sliding groove 37, thereby facilitating installation and movement. An infrared emitter 36 and an infrared receiver 39 prevent pedestrians from passing through the sliding door mounting frame 31 during movement, thereby providing a safety feature. A mounting base 41 secures a limit plate 44 and a motor mounting bracket 42. The motor mounting bracket 42 limits the position of a motor 43. The motor 43 drives a worm 45 to rotate, and the worm 45 and the transmission mechanism drive the sliding door mounting frame 31 to move, thereby opening and closing the door. The position-limiting bracket 46 limits the position of rotating shaft 1 47, which in turn secures the worm gear 48. The cooperation between rotating shaft 2 49 and worm 45 allows the sliding door mounting frame 31 to self-lock after opening and closing, preventing anyone from tampering with the door panel. Rotating shaft 2 49 rotates gear 410, which in turn moves rack 411, which in turn moves the sliding door mounting frame 31, thereby achieving the purpose of opening and closing the door. The sliding door mounting frame 31 is concealed and protected by the door guard 2.

[0034] It is worth noting that the input end of the motor 43 disclosed in the above embodiment is electrically connected to the output end of the external power supply through an external PLC controller. The motor 43 adopts a servo motor, and the external PLC controller controls the operation of the motor 43 using a method commonly used in the prior art.
