It has the function of entering, and it will have many grooves to facilitate the installation of other parts. The hollow treatment is used to reduce weight and facilitate assembly and disassembly.

Working and usage process:

When you need to open the door, use your feet to step on the foot pedal 107 on the side connected to the hook and exert downward force. The foot pedal 107 drives the foot gear 102 to rotate, and then the foot gear 102 drives the shaft gear 101 to rotate. The upper part of the shaft gear 101 The transmission shaft 201 also rotates under the rotation of the shaft gear 101. The transmission link 202 provided 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, driving the door panel 405 to surround the hinge base 205. The hinge 402 rotates, thereby opening the door panel 405. (At the same time, the rope 206 drives the door pin 302 to compress the door pin spring 301 under the pull of the transmission link 202, and moves the door pin 302 out of the door pin groove 306, so that the door panel 405 does not open when the door panel 405 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 blocks the hook 103, limiting the freedom of movement of the hook 103. Since the hook 103 is restricted movement, the pedal gear 102, the shaft gear 101 and the transmission shaft 201 are all restricted from rotating, and at this time the door panel 405 will be fixed. When a person passes the door panel and needs to close the door, stand on the opposite side of the foot pedal connected to the side with the hook, and lift the foot pedal upward with the instep of the foot. The foot pedal on the other side will move downward and press the spring. Press twice, the hook is released by the push-type elastic self-locking mechanism and the degree of freedom is restored. At this time, step on the foot pedal and push downward. The foot pedal drives the foot gear to rotate in the other direction, and then the foot gear drives the The shaft gear rotates, and the transmission shaft above the shaft gear also rotates under the rotation of the shaft gear. The transmission link provided on the transmission shaft rotates around the shaft gear and then transmits the force to the hinge base through the connecting support link, driving the door panel. Rotate around the hinge to close the door panel. During this process, the rope changes from a taut state to a relaxed state, and the door pin spring also changes from a compressed state to an elongated 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. The disc with words can show whether there is someone or no one.

This device can open and close the door through the pressing action of the foot. It also has elastic self-locking and indicating functions. It can complete a series of door entry and exit actions such as opening and closing the door with the foot. It can be used in hospitals, public toilets, hotels, restaurants and other places, thereby avoiding problems such as virus transmission and cross-infection caused by touching multiple hands in public places. Therefore, this device not only reduces the probability of infection due to direct hand contact with the door when the epidemic is severe, but also eliminates certain safety hazards and creates a safe and hygienic environment for people.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it. 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 can be equivalently replaced; and these modifications or substitutions do not deviate from the essence of the corresponding technical solutions from the technical solutions of the embodiments of the present invention. scope.
