[0038] Embodiment 1:

[0039] This embodiment provides a pedal-operated door handle, including:

[0040] A base 1, with a limiting surface 8 provided at the bottom of the base 1, and a limiting hole 9 provided on the limiting surface 8;

[0041] A handle 2, including a handle 21 and a connecting portion 22 connected to the handle 21. The connecting portion 22 is rotatably connected to the base 1, and a gear 10 is provided on the connecting portion 22;

[0042] A traction plate 3, with its top inserted into the limiting hole 9. A rack 11 is provided at the top of the traction plate 3, the bottom of the rack 11 abuts against the limiting surface 8, and the gear 10 is meshed with the rack 11;

[0043] A limiting plate 4, located below the base 1. A first limiting groove 12 is provided at the top of the limiting plate 4, and the lower end of the traction plate 3 is slidably arranged in the first limiting groove 12;

[0044] A first pedal 5, with its top hinged to the top of the limiting plate 4;

[0045] A connecting plate 6, with both ends respectively hinged to the lower end of the traction plate 3 and the bottom of the first pedal 5;

[0046] A second pedal 7, arranged at the bottom of the limiting plate 4, and a bending portion 71 is provided on the side of the second pedal 7 away from the limiting plate 4.

[0047] In this technical solution, the base 1 may include a bottom plate and a protective cover. The bottom plate can be fixed to the door panel by using screws, and the protective cover can be fixed to the bottom plate by using screws. The gear 10 and the rack 11 are arranged inside the protective cover, and the protective cover is used to cover the gear 10 and the rack 11 for protection.

[0048] The handle 2 is a conventional contact-type handle 2. The connecting portion of the handle 2 is connected to the lock core, and the door lock can be opened by rotating the handle 2. A torsion spring 18 can be arranged between the lock core and the handle 2. After the door is opened by rotating the handle 2, the handle 2 can rotate in the reverse direction and automatically reset. The handle 21 can be a long-strip-shaped handle 21 bent and connected to the connecting portion 22, or a spherical handle 21 connected to the front side of the connecting portion 22.

[0049] The traction plate 3 is a plate body with a long-strip-shaped structure. The traction plate 3 is vertically arranged and kept parallel to the surface of the door panel. The rack 11 and the traction plate 3 can be connected by using screws, which is convenient for disassembling and replacing the rack 11 or the traction plate 3.

[0050] The bottom of the rack 11 abuts against the limiting surface 8, and the limiting surface 8 is used to limit the lifting height of the rack 11 to prevent the rack 11 from disengaging from the limiting hole 9 when the handle 2 or the gear 10 is damaged.

[0051] The limiting plate 4 can be installed at the bottom of the door panel with screws. The first limiting groove 12 is used to limit and guide the bottom of the traction plate 3 to ensure that the traction plate 3 slides up and down on the limiting plate 4.

[0052] The top of the first pedal 5 is hinged to the top of the limiting plate 4. The two ends of the connecting plate 6 are respectively hinged to the lower end of the traction plate 3 and the bottom of the first pedal 5. By moving the traction plate 3 up and down, the connecting plate 6 pushes and pulls the first pedal 5 to rotate.

[0053] The second pedal 7 can be bent and connected to the bottom of the limiting plate 4, and the bent part 71 can be bent and connected to the front side of the second pedal 7.

[0054] When opening the door by hand, as Figure 1 shown, you can directly hold the handle 21 and rotate it clockwise to open the door lock, and then pull or push it outwards or inwards to open the door.

[0055] When opening the door with the foot, as Figure 1 shown, first push the first pedal 5 forward with the toe. The first pedal 5 rotates towards the door panel, thereby causing the connecting plate 6 to rotate. The top of the connecting plate 6 pushes the traction plate 3 upwards. While the traction plate 3 moves upwards, it causes the rack 11 to move upwards. The rack 11 drives the gear 10 to move clockwise, and further drives the handle 2 to rotate clockwise, thereby opening the door lock.

[0056] While pushing the first pedal 5 forward with the toe, place the sole of the foot on the second pedal 7, and the sole abuts against the bent part 71. The bent part 71 can increase the friction between the sole of the shoe and the second pedal 7. The foot can push or pull the door forward or backward through the bent part 71 to open the door.

[0057] After the door is opened, move the foot away from the first pedal 5. At this time, the handle 2 is automatically rotated counterclockwise and reset under the action of the torsion spring 18 on the lock core. Then, the gear 10 rotates counterclockwise to drive the rack 11 to move downwards, the traction plate 3 moves downwards, and the connecting plate 6 causes the first pedal 5 to rotate in the reverse direction and reset for the next time to apply pressure to the first pedal 5 to open the door.

[0058] The utility model presses on the first pedal 5 to move the rack 11 upwards, drives the gear 10 to rotate, and thus opens the door. It not only has stable operation and strong reliability, but also can improve the service life of the utility model.
