[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figures 1-3 This embodiment provides a safety protection device for rail transit platform screen doors, including a door frame 1, a screen door 2 installed on the inner side of the door frame 1, and a protective plate 23 installed on the screen door 2 to buffer the impact force received by the screen door. The protective plate 23 and the screen door 2 are the same size and can be opened and closed simultaneously. In use, this rail transit platform screen door safety protection device installs the protective plate 23 on the outer surface of the screen door 2. When the screen door 2 is impacted, the impact force is applied to the protective plate 23, which buffers the impact force, thus providing good protection for the screen door 2 and preventing the tempered glass screen door 2 from shattering under external impact, which could pose a safety hazard to passengers.

[0025] In this embodiment, as Figure 1 As shown, a protective rubber pad 3 is fixedly installed on the bottom of the outer side of the door frame 1 on the ground. A groove 31 is provided on the bottom edge of the outer side of the two shielding doors 2 on the ground. Pressure sensors 32 are symmetrically embedded at both ends of the bottom inner side of the groove 31. An entry / exit pedal 33 made of rubber material is installed on the top of the groove 31. The top of the entry / exit pedal 33 is flush with the top of the protective rubber pad 3. The protective rubber pad 3 and the rubber entry / exit pedal 33 can play a good anti-slip role and prevent passengers from slipping when entering or exiting in rainy or snowy weather.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, the entry / exit pedal 33 presses against the pressure sensor 32. The pressure sensor 32 and the alarm 11 are linked and controlled by a switch. When pressure is applied to the entry / exit pedal 33 when the platform screen door 2 is closed, the alarm 11 will automatically start. When the platform screen door 2 is open, the alarm 11 will not start. Thus, when the platform screen door 2 is closed, it can provide an alarm to passengers who cross the safety line and prevent safety accidents.

[0027] In this embodiment, as Figure 3 As shown, springs 24 are installed at the four corners and the center of the inner side of the protective plate 23. An I-shaped stainless steel edging 21 is installed on the shielding door 2. Dampers 22 are installed at the four corners and the center of the outer side of the stainless steel edging 21. The springs 24 are connected to the stainless steel edging 21, and one end of the damper 22 is connected to the protective plate 23. The damper 22 is located inside the springs 24. Therefore, the protective plate 23 can prevent the shielding door 2 from being directly impacted. At the same time, the protective plate 23 can buffer the impact force, thereby providing effective protection for the shielding door 2.

[0028] Working principle: When this rail transit platform screen door safety protection equipment is in use, the protective pad 3 and the rubber entry / exit pedal 33 provide good anti-slip effect, preventing passengers from slipping when entering or exiting in rainy or snowy weather. When the platform screen door 2 is closed, if a passenger stands on the entry / exit pedal 33 and squeezes the pressure sensor 32, the alarm 11 will sound an alarm, alerting passengers who have crossed the safety line and preventing safety accidents. When an external force impacts the protective plate 23, the protective plate 23 can prevent the platform screen door 2 from being directly impacted, and at the same time, the protective plate 23 can buffer the impact force, thus activating an effective protective function for the platform screen door 2, preventing the risk of the tempered glass platform screen door 2 shattering due to external impact and causing safety hazards to passengers.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
