Working and using process:

When you need to open the door, step on the foot pedal 107 on the side connected with the hook with your feet and press down, the foot pedal 107 drives the pedal gear 102 to rotate, then the pedal gear 102 drives the shaft gear 101 to rotate, and the upper part of the shaft gear 101 The transmission shaft 201 also rotates under the rotation of the shaft gear 101, and the transmission link 202 arranged on the transmission shaft 201 rotates around the transmission shaft 201 and then transmits the force to the hinge base 205 through the connecting support link 203, and drives the door panel 405 to surround the The hinge 402 rotates, so that the door panel 405 is opened (at the same time, the rope 206 drives the door pin 302 to compress the door pin spring 301 under the pulling of the transmission link 202, and the door pin 302 is moved out of the door pin slot 306, so that the door panel 405 does not open when it is opened. will be restricted). During this process, the hook 103 fixedly connected to the bottom of the foot pedal 107 moves to the lowest point, and the push-type elastic self-locking mechanism 105 locks the hook 103 to limit the freedom of movement of the hook 103. Since the hook 103 is restricted When moving, the pedal gear 102, the shaft gear 101 and the transmission shaft 201 are all restricted from rotating, and the door panel 405 will be fixed at this time. When people pass through the door, they need to close the door, stand on the opposite side of the foot pedal connected to the hook, lift the foot pedal up with the instep, and the foot pedal on the other side will move down to press the spring. Press the second time, the hook is released by the push-type elastic self-locking mechanism to restore the degree of freedom. At this time, step on the pedal with your foot and press down, the pedal drives the pedal gear to rotate in the other direction, and then the pedal gear drives When the shaft gear rotates, the transmission shaft on the upper part of the shaft gear also rotates under the rotation of the shaft gear, and the transmission link set on the transmission shaft rotates around the shaft gear and transmits the force to the hinge base through the connecting support link to drive the door panel. Rotate around the hinge to close the door panel. During this process, the rope is converted from a taut state to a slack state, and the door pin spring is also converted from a compressed state to an extended state. When the door is closed, the door pin enters. In the door pin slot, when the door pin is inserted into the door pin slot, the block will be pushed up, driving the disc to rotate, and the disc with words can display the status of someone or no one.

This device can realize the opening and closing of the door through the pressing action of the foot, and at the same time has the functions of self-locking and indicating, and a series of actions such as opening and closing the door can be completed with the foot. It can be used in hospitals, public toilets, hotels, restaurants. and other places, so as to avoid problems such as virus transmission and cross-infection caused by hand-to-hand contact in public places. Therefore, the device not only reduces the probability of infection due to direct contact with the door when the epidemic is severe, but also can eliminate certain safety hazards and create a safe and hygienic environment for people.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: The technical solutions described in the foregoing embodiments can still be modified, or some or all of the technical features thereof can be equivalently replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present invention. scope.
