In a preferred aspect of the present invention, the protection platform is provided with a foot protector for protecting a foot of a passenger on a side away from the elevator-side bracket.

In the present invention, it is preferable that the toe guard includes a base connected to the protection table and a collision table located on a side away from the protection table, and an arc-shaped buffer groove is provided between the base and the collision table.

Preferably, the pedal body comprises a plurality of pedals and a plurality of sunken anti-skidding grooves, and the plurality of the anti-skidding grooves are positioned between the adjacent pedals.

Preferably, a vent hole is formed in the anti-slip groove.

Preferably, an air suction device is provided below the pedal body.

Preferably, the air suction device comprises a fan protection frame, a rotating shaft positioned in the fan protection frame, and a plurality of fan blades connected with the rotating shaft.

In conclusion, the invention has the following beneficial effects:

1. the protective table can keep the user's feet away from the dangerous area where the feet are easily clamped.

2. The upper end face of the protection platform adopts an inclined design and has a guiding function.

3. The protection platform can rise under the effect of rising the device to keep the outward appearance uniformity of whole footboard body when not using, cooperation sensor technology rises when using, and science and technology degree and integration degree are high.

4. The air suction device can accelerate air flow and is favorable for heat dissipation.

FIG. 2 is a schematic view of another angle of FIG. 1;

FIG. 3 is a schematic view of a protective table and a foot protector body;

fig. 4 is a schematic view of a suction device.

In the figure:

1. the pedal comprises a pedal body, 11, a pedal body, 12, an anti-skidding groove, 2, a protection table, 21, a slope, 3, a foot protection body, 31, a bottom table, 32, a collision table, 33, a buffer groove, 4, a lifting bottom table, 5, an air suction device, 51, a ventilation hole, 52, a rotating shaft, 53, fan blades, 54 and a fan protection frame.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.

Embodiment 1, a pedal body 1 is attached to a step using a mounting link, moving forward and upward with a conveyor. The installation connecting piece, the step, the transmission device and the like are the same as those in the prior art, large changes are not needed, and detailed description is not needed here, and the invention aims at improving the pedal body 1.

As shown in fig. 1, the pedal body 1 is transversely disposed and includes a plurality of pedals 11, an anti-slip groove 12 is disposed between adjacent pedals 11, the anti-slip groove 12 is recessed toward a lower portion, and a ventilation hole 51 is disposed on a plate body in the anti-slip groove 12 for facilitating ventilation.

Protection stands 2 are provided on both sides of the step body 1, i.e., at positions close to the supports on the elevator-side end. The protection platform 2 comprises a slope 21 which is arranged in an inclined manner, and the inclined direction of the slope 21 is the horizontal direction and gradually descends downwards according to the direction close to the middle part of the pedal body 1, namely, the direction far away from the elevator side end bracket which is not shown in the drawing. Due to the existence of the protection platform 2, particularly the inclined guiding arrangement mode of the slope 21, the foot of the user can be far away from the bracket at the side end of the elevator along the direction of the slope 21 in the process of stepping down, so that the probability of foot clamping caused by the fact that the foot of the user is too close to the gap between the pedal body 1 and the bracket at the side end of the elevator is reduced to a certain extent.

In some high-grade places, the use mode of matching the inductor with the jacking device can be adopted. For example, a sensor is arranged at a position of the pedal body 1 close to the elevator side end bracket, such as an infrared sensor, and senses that the foot of the human body is at the position, so that the protection platform 2 ascends, and the foot of the human body is naturally pushed open transversely in the ascending process due to the slope 21.

The concrete structure can be provided with a lifting bottom platform 4, a jacking device, such as a gas rod and other parts, is arranged on the lifting bottom platform, after receiving signals of a sensor, a control device controls the gas rod to jack, and the upper end of the gas rod is connected with the protection platform 2.

As shown in fig. 2 and 4, the present invention further includes a suction device 5 to increase the heat dissipation of the device. Because the lower part of the pedal body 1 is provided with a plurality of mechanical parts, the pedal body has larger heat productivity after long-time work, and is not beneficial to the operation of equipment. The air suction device 5, for example, a motor, drives the rotating shaft 52 to rotate, and the fan blades 53 rotate along with the rotating shaft, so as to accelerate the air flow and facilitate heat dissipation.
