[0022] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0023] Example one

[0024] Please refer to Figures 1-5 The protection device for preventing elevator from opening door by mistake of the embodiment comprises an elevator door frame 1 and two mounting frames 3.

[0025] Elevator door frame 1: As a fixed part of the elevator, the elevator door frame 1 not only constitutes the appearance frame of the elevator landing door, but also provides a stable support foundation for the mounting frame 3 and the baffle 2. It is the installation support of the entire protection device, which ensures the close combination of the device and the elevator.

[0026] Mounting frame 3 (two): The two mounting frames 3 are symmetrically installed on one side of the elevator door frame 1, which not only serves as the sliding track of the baffle 2, but also bears the driving assembly, ensuring that the baffle 2 can move smoothly and accurately in the horizontal direction. The design of the mounting frame 3 makes the protection device easily adapt to elevator door frames of different sizes, improving the versatility and flexibility of the device.

[0027] Baffle 2 (one in each mounting frame): The baffle 2 is a key component for preventing elevator from opening door by mistake, which can slide out from one side of the elevator door frame 1 under the push of the driving assembly, completely blocking the opening part of the elevator landing door. When the elevator car does not arrive, the existence of the baffle 2 effectively prevents the opening of the landing door, thereby ensuring the safety of passengers.

[0028] Driving assembly (one on the top of each mounting frame): The driving assembly is the power source for the movement of the baffle 2, which can accurately control the movement of the baffle 2 in the horizontal direction of the mounting frame 3 after receiving the signal from the control switch. The design of the driving assembly ensures that the movement of the baffle 2 is both fast and stable, which is the core component for realizing the safety control of the elevator landing door.

[0029] Control switch (one on the side wall of one side mounting frame): The control switch is the "brain" of the entire protection device, connected with the elevator system, responsible for receiving the instructions of the elevator system and sending signals to the two driving assemblies according to the instructions. The precise control of the control switch ensures that the baffle 2 moves at the right time, thereby realizing the safety locking and unlocking of the elevator landing door.

[0030] Two installation frames 3 are symmetrically installed on one side of the elevator door frame 1, the inside of each installation frame 3 is slidably connected with a baffle 2, and the top of each installation frame 3 is connected with a driving assembly for driving the baffle 2 to move horizontally along the installation frame 3, and the side wall of the installation frame 3 on one side is connected with a control switch for electrical connection with the two driving assemblies.

[0031] Embodiment two

[0032] Please refer to Figures 1-5 As shown in the figure, the baffle 2 of the protective device for preventing the elevator from being opened by mistake in this embodiment is provided with a plurality of through grooves 5 on one side, and the installation frame 3 is bolted and fixedly connected with the side wall of the elevator door frame 1. Specifically, by providing the plurality of through grooves 5 on one side of the baffle 2, the weight of the baffle 2 is reduced, the cost is reduced, and the pressure on the moving structure is also reduced, thereby ensuring the normal operation of the structure.

[0033] A sliding groove 7 is formed in the bottom of the inner cavity of the installation frame 3, and a sliding plate 13 adapted to the sliding groove 7 is fixedly connected to the bottom of the baffle 2, and the length of the sliding plate 13 is the same as that of the baffle 2. Specifically, by providing the sliding groove 7 in the bottom of the inner cavity of the installation frame 3 and the sliding plate 13 fixedly connected to the bottom of the baffle 2, the stable sliding of the baffle 2 in the installation frame 3 is realized. The matching design of the sliding plate 13 and the sliding groove 7 ensures the stability and accuracy of the baffle 2 during movement, avoiding potential safety hazards caused by shaking or deviation.

[0034] A guide groove 12 is formed in the bottom of each side of the baffle 2, and a guide plate 8 adapted to the guide groove 12 is fixedly connected to the inside of each side of the installation frame 3. Specifically, by providing the guide groove 12 in the bottom of each side of the baffle 2 and the guide plate 8 fixedly connected to the inside of each side of the installation frame 3, the stability and guidance of the baffle 2 during movement are further enhanced. The matching design of the guide groove 12 and the guide plate 8 can ensure that the baffle 2 always maintains the correct direction during movement, avoiding the phenomena of jamming or damage caused by deviation from the track.

[0035] Embodiment three

[0036] Please refer to Figures 1-5 As shown in the figure, the top end of the installation frame 3 is provided with a top groove 9, and the top of the installation frame 3 is connected with a mounting bracket 4. Specifically, by bolted and fixedly connecting the installation frame 3 with the side wall of the elevator door frame 1, and providing the top groove 9 at the top end of the installation frame 3 and the mounting bracket 4 connected therewith, the stability and firmness of the installation frame 3 and the baffle 2 inside are ensured. This installation method is simple and reliable, facilitating the quick installation and disassembly of the device, while ensuring the stability and durability of the device during long-term use.

[0037] The gear plate 10 is rotatably connected in the mounting frame 4, a driving motor 11 for driving the gear plate 10 to rotate is arranged on one side, the top of the baffle 2 is connected with the toothed plate 6, the gear plate 10 is connected with the toothed plate 6 through the engagement of the clamping teeth, specifically, the driving assembly is arranged through the gear plate 10 rotatably connected in the mounting frame 4, the driving motor 11 arranged on one side, the toothed plate 6 connected with the top of the baffle 2 and the engagement of the gear plate 10 and the toothed plate 6, so that the precise control of the driving assembly on the baffle 2 is realized. When the driving motor 11 is started, the baffle 2 can be smoothly driven to move along the horizontal direction of the mounting frame 3 through the engagement transmission of the gear plate 10 and the toothed plate 6, so that the movement precision and response speed of the baffle 2 are ensured.

[0038] The scheme has the following working process:

[0039] When the elevator normally operates to the specified floor and prepares to open the door, the elevator system first activates the signal connected with the control switch, and the control switch sends instructions to the driving assembly arranged on the top of the two mounting frames 3. After receiving the signal, the driving assembly is started, and the baffle 2 is smoothly moved along the horizontal direction of the mounting frame 3 through the internal mechanical structure, such as the driving motor 11 and the gear plate 10. The driving motor 11 drives the gear plate 10 to rotate, and the gear plate 10 is engaged with the toothed plate 6 on the top of the baffle 2 through the clamping teeth, so that the precise transmission control is realized. During the movement of the baffle 2, the slide plate 13 fixed at the bottom of the baffle 2 slides along the sliding groove 7 at the bottom of the inner cavity of the mounting frame 3, and at the same time, the guide grooves 12 on the two sides of the baffle 2 are tightly matched with the guide plates 8 in the mounting frame 3, so that the stability and accuracy of the movement of the baffle 2 are ensured. When the baffle 2 completely covers the opening part of the elevator landing door, the elevator landing door is effectively locked, and the misopening situation is prevented. When the elevator car arrives and stops stably, the control switch sends a signal again, and the driving assembly operates reversely, and drives the baffle 2 to smoothly slide back to the inside of the mounting frame 3 along the original path through the same transmission mechanism, so that the passengers can normally enter and exit the elevator.
