[0035] In this embodiment, the mounting base 301 facilitates the installation and distribution of the warning light 302, so that the warning light 302 is distributed at the top position of the entrance and exit of the elevator shaft 101. The warning light 302 can provide a lighting warning operation in the event of a fault, which is beneficial to remind passengers to pay attention to safety, thereby effectively improving the prompt effect. A protective cover 303 is installed at the bottom of the mounting base 301 and is arranged on the outside of the warning light 302, which is beneficial to provide protection for the warning light 302 when transporting large objects, avoiding direct squeezing on the warning light 302 to cause damage, and saving the cost of use. The sealing ring 304 is arranged on the outside of the protective cover 303 to improve the sealing after installation, thereby ensuring the use effect.
[0036] Example 3: Figures 2-7 As shown, guide rail frames 102 are provided at the four inner corners of the elevator shaft 101, and the guide rail frames 102 are distributed on the outside of the elevator car 103. An upper track 104 for opening and closing the elevator door is fixedly installed on the top of one side of the inner wall of the elevator shaft 101, and a lower track 105 for opening and closing the elevator door is fixedly installed on the bottom of one side of the inner wall of the elevator shaft 101. Electric side push telescopic rods 106 are provided on both sides of the inner wall of the elevator shaft 101, and the output ends of the electric side push telescopic rods 106 are connected to the elevator safety door 107.

Lateral rollers 108 are symmetrically installed on the top of the elevator, and translation rollers 109 are symmetrically installed on the bottom of the elevator safety door 107. The lateral rollers 108 are movably installed on the inner side of the elevator door opening and closing upper track 104, and the translation rollers 109 are movably installed on the inner side of the elevator door opening and closing lower track 105. Slots are opened through the front of the elevator shaft 101 and the elevator car 103. A rotating column is provided between the lateral rollers 108 and the elevator safety door 107, and a support seat is provided between the translation rollers 109 and the elevator safety door 107.
[0037] In this embodiment, the guide rail frame 102 facilitates the installation and lifting and lowering guidance of the elevator car 103, thereby improving the operation stability. The elevator door opening and closing upper track 104 facilitates the provision of an installation guide position for the lateral roller 108, so that the top position of the elevator safety door 107 ensures smooth opening and closing operation. The elevator door opening and closing lower track 105 facilitates the provision of an installation support position for the translation roller 109, and facilitates the stable rolling movement operation of the translation roller 109 on the inner side of the elevator door opening and closing lower track 105, thereby improving the operation stability of the elevator safety door 107 during the opening and closing process. The electric side push telescopic rod 106 cooperates with the controller for electronically controlled telescopic adjustment, so that the elevator safety door 107 can be pulled or pushed to achieve flexible opening and closing operations, effectively improving the convenience of use and ensuring the stability of use.
[0038] In the application, the elevator door safety protection device is used first to set the elevator car 103 on the inner side of the elevator shaft 101, which facilitates people to take the elevator and achieve the effect of conveniently going up and down the stairs. The elevator safety door 107 is arranged at the entrance and exit of each floor of the elevator shaft 101, which can provide protection and prevent falling from the building and other situations, improve the protection effect, ensure safety, and facilitate the installation of the structure of the safety protection component on the opposite side of the two elevator safety doors 107, which improves the stability of the operation. The guide rail frame 102 facilitates the installation and lifting guide of the elevator car 103, improves the stability of the operation, and facilitates the installation and guide of the lateral roller 108 on the upper track 104 of the elevator door opening and closing, which ensures the stable opening and closing operation of the top of the elevator safety door 107. The lower track 105 of the elevator door opening and closing facilitates the installation and support of the translation roller 109, which facilitates the stable rolling movement of the translation roller 109 on the inner side of the lower track 105 of the elevator door opening and closing, thereby improving the stability of the operation of the elevator safety door 107 during opening and closing. The electric side push telescopic rod 106 cooperates with the controller to perform electric control expansion adjustment, which can pull or push the elevator safety door 107 to achieve flexible opening and closing operation, effectively improve the convenience of use, and ensure the stability of use.
[0039] By symmetrically installing the infrared receiving strip 202 on the inner side of the embedding groove 110 and fixing the infrared receiving strip 202 through the installation strip 201, the stability is ensured, and a plurality of infrared emission modules 203 are uniformly distributed on the infrared receiving strip 202, which is conducive to emitting infrared rays through the infrared emission modules 203 and receiving the emitted infrared rays through the infrared receiving strip 202. When an obstacle enters the sensing area, the infrared light is blocked, and the infrared receiver outputs a corresponding signal to the control module, thereby realizing the operation of quickly stopping the further closing of the elevator safety door 107. The infrared receiving strip 202 and the infrared emission module 203 are double-layered, which is conducive to providing multiple protection and improving the use effect and detection accuracy. The extrusion strip 204 is arranged in the middle part of the inner side of the embedding groove 110, i.e. the position between the two infrared receiving strips 202, and the extrusion strip 204 is in a convex state when the elevator safety door 107 is opened. Thus, if the position of the extrusion strip 204 is pressed during the closing process of the elevator safety door 107, the reset spring 206 will be compressed, and the guide block 205 will move on the connecting plate 207, causing the extrusion of the mounting rod 210 to the position of the pressure sensor 209. When the pressure sensor 209 senses the pressure, it will send a corresponding signal to the control module, causing the elevator safety door 107 to stop closing. At the same time, the electric side-pushing telescopic rod 106 pulls the elevator safety door 107 to open, and the reset spring 206 pushes the extrusion strip 204 back to its original position under the condition of no pressure, releasing the pressure detection. This effectively avoids the situation where the elevator safety door 107 causes harm to the human body when it is closed, effectively improving the safety during use. In addition, the electric telescopic rod 208 is arranged at the side of the connecting plate 207 and the inner side of the embedding groove 110. Through the electric telescopic rod 208, the extrusion strip 204 can be pulled back and retracted to the inside of the embedding groove 110 when the elevator safety door 107 is close to the closed state, avoiding the situation of misoperation caused by the convex state, to ensure the complete operation of the elevator safety door 107.
[0040] The installation seat 301 facilitates the installation and distribution of the warning light 302, so that the warning light 302 is distributed at the top position of the entrance of the elevator shaft 101. The warning light 302 can provide lighting warning operation in case of failure, which is conducive to reminding passengers to pay attention to safety, thereby effectively improving the prompting effect. The protective cover 303 is installed at the bottom of the installation seat 301 and is arranged outside the warning light 302, which is conducive to providing protection for the warning light 302 when large objects are carried, avoiding direct extrusion on the warning light 302 and causing damage, and saving the use cost. The sealing ring 304 arranged outside the protective cover 303 can improve the sealing performance after installation, thereby ensuring the use effect.
