Description

Light nonmetal pedal for opening door by foot

Technical Field

The invention relates to the technical field of sliding doors, in particular to a light nonmetal pedal for opening a door.

Background

The transmission route is the process that pathogens are discharged from the infection source to the outside of the body and reach and invade new susceptible people through a certain transmission mode. Contact propagation is generally classified into direct contact propagation and indirect contact propagation. In public places, the contact of susceptible people with daily necessities polluted by excrement or secretion of infectious sources, such as hand-opening sliding doors, also becomes a common transmission way, and the foot door opening device can prevent virus transmission to a great extent. In biological/chemical laboratory and other places, the foot door opener can prevent others from contacting the residual of toxic reagent.

The patent publication No. CN210032975U, "a foot door opener", proposes a foot door opener, which includes a fixed shell and a pedal plate, wherein the pedal plate is slidably connected to the fixed shell, and a rebounder matched with the pedal plate is disposed on the fixed shell, and the pedal plate can be pushed to slide through the rebounder. The fixed shell is arranged at a proper position of the door body according to requirements, and the door body is convenient to step on by feet; the pedal plate is connected with the fixed shell in a sliding mode, so that the pedal plate can stretch out and draw back. The pedal can be pushed out for use through the rebounder according to the requirement; after use, the pedal is pushed back to prevent the pedal from being exposed outside. The metal material is easy to prepare by adopting a stamping process, and although the manufacturing cost is controlled to a certain extent by the technology, the production period of the stamping die is long, about 3 months, and the requirement on cargo supply in an emergency state cannot be met.

At present, for a sliding door in a public place, reinstallation of an automatic door or an electric foot door opener is not practical, mainly because the cost of replacing the door is high and a circuit system needs to be rebuilt. Therefore, there is an urgent need to develop a low-cost door opening device.
