Both driving frames 4 are slidably arranged in the bracket 2. Two levers 5 are provided. Two levers 5 are provided. Both levers 5 are arranged on the valve 1. Both levers 5 are provided with sliding grooves. The driving rod 6 is slidably arranged in the two sliding grooves. The driving rod 6 is arranged between the two driving frames 4. Through the cooperation between the bracket 2, the pedal 3, the driving frame 4, the lever 5, the driving rod 6, the opening mechanism and the closing mechanism, the workers are taught to step on the pedal 3 to control the opening and closing of the water flow, without the need for the workers' hand contact, and it is not easy to affect the use of the people behind.
[0046] The opening mechanism is arranged in the bracket 2, and the opening mechanism corresponds to one of the pedals 3 and one of the driving frames 4, and is used to open the valve 1. The opening mechanism includes: a first slide bar 7, a first baffle plate 8, a first spring 9, a slide tube 10, a connecting rod 11, a slider 12 and a pressure rod 13. The first slide bar 7 is fixedly connected in the bracket 2, the driving frame 4 is slidably arranged on the first slide bar 7, the first baffle plate 8 is fixedly connected to the first slide bar 7, the first spring 9 is sleeved on the first slide bar 7, the first spring 9 is arranged between the first baffle plate 8 and the driving frame 4, the slide tube 10 is rotatably arranged in the bracket 2, and one end of the connecting rod 11 is slidably arranged in the slide tube 10. The other end of the connecting rod 11 is rotatably connected to the driving frame 4, the slider 12 is slidably set on the sliding tube 10, the pressure rod 13 is fixedly connected to the pedal 3, and the bottom end of the pressure rod 13 is rotatably connected to the slider 12. Specifically, the worker steps on the pedal 3 to press the pedal 3 downward. When the pedal 3 is pressed downward, the pressure rod 13 and the slider 12 are pressed downward. When the slider 12 is pressed downward, the sliding tube 10 and the connecting rod 11 are driven to swing downward. At this time, the connecting rod 11 slides in the sliding tube 10, and the slider 12 slides on the sliding tube 10, thereby driving the driving frame 4 to descend. When the driving frame 4 descends, it drives the driving rod 6 and the lever 5 to descend, thereby opening the valve 1 to allow water to flow out.
[0047] The closing mechanism is arranged in the bracket 2, and the closing mechanism corresponds to another pedal 3 and another driving frame 4, and is used to close the valve 1. The closing mechanism includes: a second slide bar 14, a second baffle plate 15, a second spring 16, a lifting rod 17, a lever 18 and a rotating shaft 19. The first spring 9 and the second spring 16 are respectively arranged at the upper and lower ends of the two driving frames 4. The second slide bar 14 is fixedly connected in the bracket 2, and the driving frame 4 is slidably arranged on the second slide bar 14. The second baffle plate 15 is fixedly connected to the second slide bar 14. The second spring 16 is arranged between the second baffle plate 15 and the driving frame 4. The top end of the lifting rod 17 is connected to the driving frame 4. Rotational connection, the lever 18 is rotatably set in the bracket 2, one end of the lever 18 is rotatably connected to the bottom end of the lifting rod 17, the rotating shaft 19 is rotatably set at the other end of the lever 18, the rotating shaft 19 contacts the pedal 3, and a rotating seat 23 is fixedly connected to the lever 18, and the rotating shaft 19 is rotatably connected in the rotating seat 23. Specifically, the worker steps on another pedal 3 to drive the rotating shaft 19 and the lever 18 to swing downward, and the lever 18 drives the lifting rod 17 to rise when it swings, and the lifting rod 17 drives the driving frame 4 to slide upward on the sliding rod when it rises, thereby driving the driving rod 6 to rise, thereby driving the lever 5 to swing upward, thereby closing the valve 1.
[0048] Among them, a guide assembly is arranged in the bracket 2, and the guide assembly includes: a guide frame 20, a guide rail 21 and a lifting block 22. There are two guide frames 20, and the two guide frames 20 are fixedly connected in the bracket 2. There are multiple guide rails 21, and every two adjacent guide rails 21 are respectively arranged in the two guide frames 20. There are two lifting blocks 22, and the two lifting blocks 22 are respectively slidably arranged in the two guide frames 20. The driving rod 6 is rotatably connected between the two lifting blocks 22. Specifically, the lifting block 22 slides in the guide frame 20, so as to guide and limit the driving rod 6 when it moves up and down.
[0049] In this embodiment, when a worker needs to wash his hands, the worker steps on the pedal 3 to press the pedal 3 downward. When the pedal 3 is pressed downward, the pressure rod 13 and the slider 12 are pressed downward. When the slider 12 is pressed downward, the slide tube 10 and the connecting rod 11 are driven to swing downward. At this time, the connecting rod 11 slides in the slide tube 10, and the slider 12 slides on the slide tube 10, thereby driving the driving frame 4 to descend. When the driving frame 4 descends, the driving rod 6 and the lever 5 are driven to descend, thereby opening the valve 1 to allow water to flow out. When the valve 1 needs to be closed, the worker steps on another pedal 3 to swing the rotating shaft 19 and the lever 18 downward. When the lever 18 swings, the lifting rod 17 is driven to rise. When the lifting rod 17 rises, the driving frame 4 slides upward on the slide rod, thereby driving the driving rod 6 to rise, thereby driving the lever 5 to swing upward, thereby closing the valve 1. When one pedal 3 responsible for opening is stepped on, the other pedal 3 is lifted up through a series of transmissions, so that the two pedals 3 are not easily affected by each other when stepped on.
[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
