Description

Technical Field

[0001] This utility model relates to the technical field of elevator foot protection plates, specifically an elevator foot protection plate protective device. Background Technology

[0002] Elevator foot guards are one of the main safety devices for elevators. When an elevator malfunctions and traps a person above the landing level, the person is likely to fall into the elevator shaft when exiting the elevator. Elevator foot guards are fixed to the car sill bracket located at the front of the car floor, reducing the distance between the car floor and the landing sill, effectively preventing people from accidentally falling into the elevator shaft when exiting the elevator.

[0003] The existing foot guards are fixedly installed at the bottom of the car. For cases where the pit is shallow, the length of the foot guards needs to be shortened to prevent them from colliding with the pit. This would affect the protective function of the foot guards and would not comply with relevant regulations.

[0004] In related technologies, please refer to Chinese Patent No. CN221587771U, which specifically discloses an elevator foot guard. This elevator foot guard, when in use, incorporates a sliding plate. When the elevator reaches the bottom station, the sliding plate comes into contact with the pit and receives an upward force, causing it to slide upwards along a track, thereby reducing the overall height of the foot guard. When the elevator moves upwards, the sliding plate returns to its original position under the action of a spring. Its structure is simple and easy to use.

[0005] The applicant found shortcomings in the use of the aforementioned elevator foot guard: Although the sliding plate can be extended and adjusted to better ensure the usable area of ​​the elevator foot guard and increase the safety of protection, there are still shortcomings in actual use: For example, the sliding plate does not have a good reinforcement structure after it is extended, and the protection and support of the sliding plate is mainly provided by rollers and guide rods for a very small area, which reduces the stability of the sliding plate protection support. At the same time, the surface of the sliding plate is attached to the bottom of the fixed plate, and the surface of the sliding plate does not have a good anti-slip structure, which poses a safety hazard.

[0006] In view of this, this technical solution proposes an elevator foot protection device to better solve the problems mentioned above. Utility Model Content

[0008] Both sides of the fixed plate are provided with sliding grooves, and the sliding grooves are provided with rollers for limiting and driving the sliding plate.

[0009] The sliding plate is provided with a bending part, and the fixing plate is provided with an extension part on one side of the bending part. A positioning plate is fixed on the side of the sliding plate away from the bending part, and a reinforcing plate is fixed between the positioning plate and the bending part. A reinforcing guide sleeve is fixed on the extension part, and the reinforcing guide sleeve is movably inserted into the bending part. A reinforcing adjustment rod is slidably provided inside the reinforcing guide sleeve, and the outer end of the reinforcing adjustment rod is fixedly connected to the positioning plate. Limit grooves are provided on both sides of the inside of the fixing plate. A reinforcing limiting plate is fixed at the matching position between the sliding plate and the limiting groove and is slidably provided inside the limiting groove.

[0010] The fixed plate has an internal movable groove, and the surface of the fixed plate is provided with anti-slip protrusion one. The surface of the sliding plate is provided with anti-slip protrusion two that can be stored inside the movable groove.

[0011] In a preferred embodiment, the sliding plate and the bending portion are an integral structure, and the bending portion and the extension portion are disposed opposite to each other.

[0012] In a preferred embodiment, a guide rod is mounted on the extension, and the guide rod is movably inserted into the bend.

[0013] In a preferred embodiment, a spring is sleeved on the guide rod located inside the bent portion and the extension portion, with one end of the spring fixed to the extension portion and the other end of the spring fixed to the bent portion.

[0014] In a preferred embodiment, the reinforcing plate is fixed to the surface of the sliding plate, and there are at least four reinforcing plates.

[0015] In a preferred embodiment, the second anti-slip protrusion is higher than the depth of the movable groove, and both the first and second anti-slip protrusions are equidistant.

[0016] In a preferred embodiment, the reinforcing limiting plate and the sliding plate have the same length, and the reinforcing limiting plate is adapted to the limiting groove.

[0017] In a preferred embodiment, the top of the fixing plate is provided with a pivot for rotating the fixing plate at the bottom of the elevator car.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: this technical solution strengthens and improves upon the problems existing in the prior art, increases the stability of the sliding plate protective support during use, and provides a second anti-slip protrusion that can be stored and used on the sliding plate, further enhancing the anti-slip effect of the sliding plate during use. Based on the two effects mentioned above, it is better to ensure that there are fewer safety hazards.

[0019] 1. In this utility model, a reinforcing plate is fixed between the bending part and the positioning plate for reinforcement.

A reinforcing adjusting rod is slidably arranged inside the reinforcing guide sleeve, and the reinforcing adjusting rod is fixed to the positioning plate, which can better reinforce and protect the sliding plate. Finally, limit grooves are provided on both sides inside the fixed plate, and a reinforcing limit plate for fixed connection with the sliding plate is slidably installed inside the limit groove, which can further reinforce and protect the sliding plate. The above-mentioned structures all reinforce and protect the sliding plate, increasing the stability of the sliding plate in use.

[0020] 2. In this utility model, a movable groove is provided inside the fixed plate, and an anti-slip protrusion is provided on the sliding plate. The anti-slip protrusion ensures the anti-slip rubber on the surface of the sliding plate. At the same time, when the sliding plate moves, the anti-slip protrusion can be automatically stored in the movable groove, without affecting the normal extension and retraction of the sliding plate.
