[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides a technical solution:

[0028] See also Figures 1 to 4 A shielding door with automatic static removal comprises a door body 1, a pre-embedded shell 2 is arranged at the bottom end of the door body 1, and a protective mechanism 3 is arranged inside the pre-embedded shell 2; the protective mechanism 3 comprises a limiting groove 301, the limiting groove 301 is arranged at a position corresponding to the top of the pre-embedded shell 2 of the door body 1, a connecting block 302 is fixed to one end of the door body 1 that penetrates the limiting groove 301, a placement groove 304 is arranged at the center position of the bottom end of the pre-embedded shell 2, and a static elimination rod 306 is embedded at a position corresponding to the placement groove 304 on the upper part of the pre-embedded shell 2, and the placement groove A pressing block 303 is passed through the interior of 304, a spring 305 is installed between the pressing block 303 and the placement groove 304, a placement shell 307 is fixed to the front end of the embedded shell 2, and a warning light 308 is embedded on the top of the placement shell 307. The door body 1 forms a sliding structure with the embedded shell 2 through the connecting block 302, a sliding structure is formed between the connecting block 302 and the limiting groove 301, a sliding structure is formed between the pressing block 303 and the embedded shell 2, and an elastic structure is formed between the pressing block 303 and the placement groove 304 through the spring 305.

[0029] By adopting the above technical scheme, when the switch of the door body 1 is closed, the connecting block 302 can be driven to slide along the limiting groove 301 in the embedded shell 2, thereby pressing or releasing the pressing block 303, allowing the pressing block 303 to enter the placement groove 304, thereby opening and closing the static elimination rod 306 and the warning light 308. Before the door body 1 is opened, the static elimination rod 306 eliminates static electricity in the surrounding environment, and cooperates with the anti-static coating on the outer wall of the door body 1 to improve the quality of static elimination. When the door body 1 is not opened, the warning light 308 reminds pedestrians to avoid approaching and causing danger. The spring 305 facilitates the reset of the pressing block 303 after the door body 1 is opened and closed, thereby closing the static elimination rod 306 and the warning light 308.

[0030] Specifically, Figure 1 , Figure 5 and Figure 6 As shown, one side of the housing shell 307 at the front end of the embedded shell 2 is connected to a fixed shell 4, an end of the fixed shell 4 away from the embedded shell 2 is fixed with an extension shell 5, a trigger switch 7 is embedded on one side of the interior of the embedded shell 2, a resistance block 6 is fixed on one side of the outer wall of the connecting block 302, a safety mechanism 8 is arranged inside the fixed shell 4, the safety mechanism 8 includes a motor 801, the motor 801 is embedded in the interior of the fixed shell 4, a worm 802 is connected to the power output end of the motor 801, a worm wheel 803 is connected to one side of the outer wall of the worm 802, a rotating rod 804 is passed through the interior of the worm wheel 803, the safety mechanism 8 also includes a rotating block 806, the rotating block 806 is fixed to the outer wall of the rotating rod 804 that penetrates the end of the extension shell 5, and a baffle 805 is fixed on the top of the rotating block 806.

[0031] By adopting the above technical solution, when the door body 1 is fully opened, the resistance block 6 is driven by the connecting block 302 to resist the trigger switch 7, and the motor 801 is started. The rotation rod 804 is rotated through the transmission of the worm 802 and the worm wheel 803, so that the rotating block 806 drives the baffle 805 to enter the extension shell 5 to allow pedestrians to enter. When the door body 1 is closed, the resistance block 6 is away from the trigger switch 7, so that the motor 801 rotates in the opposite direction, allowing the baffle 805 to reset to prevent pedestrians from getting too close to the platform before entering the subway.

[0032] Working principle: When the door body 1 is switched on and off, it drives the connecting block 302 to slide along the limit groove 301 in the embedded shell 2. When the door body 1 is closed, the connecting block 302 contacts and presses the pressing block 303, and is retracted into the placement groove 304 by the spring 305, and contacts the switch of the static elimination rod 306 and the warning light 308 below, which has the effect of removing static electricity. At the same time, the warning light 308 reminds you not to approach. When the subway enters the station and the door body 1 is started, the connecting block 302 slides through the spring 305 to reset the pressing block 303, thereby disconnecting the static elimination rod 306 that has been completely eliminated, and closing the door body 1 at the same time. The warning light 308 is embedded in the housing 307, and the components of the safety mechanism 8 are assembled and supported through the fixed shell 4 and the extension shell 5. When the door body 1 is closed, the baffle 805 passes through the extension shell 5 to prevent pedestrians from approaching. When the door body 1 is opened and closed, the resistance block 6 fixed by the connecting block 302 touches the trigger switch 7, and the motor 801 is started, so that the rotating rod 804 drives the rotating block 806 through the transmission of the worm 802 and the worm wheel 803, so that the baffle 805 enters the extension shell 5 to allow pedestrians to enter. When the door body 1 is closed, the connecting block 302 is away from the trigger switch 7 and closes to reset the baffle 805.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
