When the flip plate is fully opened upward, the pressure value in the disinfection tank 31 reaches a peak value. At this time, the pressure valve 36 is opened, and the disinfectant in the disinfection tank 31 enters the through hole of the vertical plate through the conduit 34. At this time, the vehicle passes through the device. During the passage of the vehicle, the vehicle is disinfected through the spray hole 40 to reduce the vehicle from bringing external viruses into the garage; the one-way valve 33 has a one-way guiding function. The pressure valve 36 and the one-way valve 33 are both prior art and will not be described in detail here. The damping spring 38 here is used to limit the stroke of the piston 41 driven by the top column 37 to move to the pressurized pipe, thereby controlling the pressure of the pressurized pipe.

[0032] The one-way locking component includes a placement box 10 fixedly connected to the right vertical plate 5. The inner side of the placement box 10 is hollow and an open groove is opened on the lower side. A ratchet 20 is arranged on the upper inner side of the placement box 10, and the ratchet 20 is fixedly connected to the rotating shaft 13 on the right side. A stepped shaft 21 is rotatably connected to the lower inner side of the placement box 10, and an adjusting plate 22 is fixedly arranged on the middle side of the stepped shaft 21. Paddles 23 are arranged on the front and back sides of the adjusting plate 22. The lower side of the paddle 23 is rotatably connected to the placement box 10, and the spatial position between the two paddles 23 contacts the adjusting plate 22. The top of the right paddle 23 is meshed with the ratchet 20. The ends of the two paddles 23 away from each other are fixedly connected with a telescopic spring 25, and the other sides of the telescopic springs 25 are fixedly connected to the inner wall of the placement box 10. A servo motor 17 is connected to the right end of the stepped shaft 21, and the outer side of the servo motor 17 is fixedly connected to the placement box 10. A hollow protective shell 11 is fixedly connected to the outer side of the placement box 10, and the servo motor 17 is located in the protective shell 11.

[0033] When the rotating shaft 13 is rotated in the forward direction, the rotating shaft 13 on the right side rotates during the forward rotation of the flip plate 7, driving the ratchet 20 to rotate. Since the ratchet 20 is meshed with the right baffle, the rotating shaft 13 on the right side can achieve unidirectional rotation, which can effectively prevent the active motor power from disappearing and the flip plate 7 from losing external force and moving downward, causing damage to the passing vehicles below. The tension spring plays a damping role in preventing the paddle 23 from moving away from the ratchet 20, so that the right baffle is in contact with the ratchet 20 during the rotation of the ratchet 20. Meshing connection. When the servo motor 17 is turned on, the servo motor 17 drives the stepped shaft 21 to reverse, and the stepped shaft 21 mobilizes the adjustment plate 22 to rotate, so that the right end face of the adjustment plate 22 is in contact with the right end face of the baffle on the left, and then the baffle on the left is meshed and connected with the ratchet 20. At the same time, the baffle on the right is subjected to a pressure in the right direction, so that the baffle on the right moves to the right and disengages from the ratchet 20. At this time, the direction of the one-way locking of the rotating shaft 13 is changed to prevent the risk of accidental injury caused by human force applied to the flip plate 7.

[0034] The upper end of the paddle 23 is provided with an oblique groove, and the lower part of the paddle 23 is rotatably connected to a short shaft 24, and the left end of the short shaft 24 is fixedly connected to the placement box 10. The front end surface of the adjustment plate 22 is trapezoidal, and the rear end surface of the adjustment plate 22 is flat-cut. The contact area between the rear end surface of the adjustment plate 22 and the rear side paddle 23 is greater than the contact area between the front end surface of the adjustment plate 22 and the front side paddle 23. By setting a T-shaped adjustment plate 22, the two ends of the adjustment plate 22 respectively abut against one side of the two paddles 23, so that the two paddles 23 are separated and engaged with the ratchet 20, thereby changing the direction of the one-way locking of the rotating shaft 13.

[0035] A limit rod 19 is fixedly arranged on the right side of the stepped shaft 21, and blocking columns 18 are arranged on the front and rear sides of the limit rod 19, and the blocking columns 18 are fixedly connected to the right end surface of the placement box 10, and the limit rod 19 and the blocking column 18 are both located inside the protective shell 11. The fixed arrangement of the limit rod 19 and the stepped shaft 21 facilitates the synchronous rotation of the limit rod 19 and the stepped shaft 21, and the blocking column 18 is used to limit the rotation angle of the limit rod 19, thereby limiting the rotation angle of the stepped shaft 21.

[0036] The upper and lower ends of the vertical plate 5 are respectively fixed with a first top rod and a second top rod, and the upper rear end of the support plate 3 is fixed with a third top plate 4. The first top plate 2, the second top plate 6 and the third top plate 4 are all provided with assembly holes. The two first top plates 2 and the third top plates 4 are fixed to the position of the wall top, and the two second top plates 6 are fixed to the position of the ground by passing locking screws through the assembly holes.

[0037] The end of the pull rod 9 away from the sleeve 29 is fixedly connected with a short rod 28, and a through groove 30 is opened in the middle side of the T-shaped slider 26. The short rod 28 is located in the through groove 30 and is rotatably connected to both sides of the through groove 30. The T-shaped slider 26 is driven by the pull rod 9 to move freely in the support plate 3, thereby facilitating the free flipping of the flip plate 7.

[0038] The horizontal plate 1, the turning plate 7, the vertical plate 5 and the supporting plate 3 are all made of stainless steel, which can reduce the corrosion of rainwater and increase the service life of the device.

[0039] When the present invention is in use, firstly, the upper and lower sides of the vertical plate 5 are fixed on both sides of the wall position of the garage door, and the rear end of the support plate 3 is fixed to the top of the garage wall. When the vehicle enters or exits the garage, by turning on the power motor 14, the power motor 14 drives the rotating shaft 13 to rotate in the forward direction, the rotating shaft 13 drives the rotating arm 12 to rotate, and the two rotating arms 12 drive the flip plate 7 to flip upward. The sliding component is connected to the flip plate 7, so that the upper side of the flip plate 7 slides along the front and rear sides of the support plate 3, and then the upper side position of the two vertical plates 5 moving the flip plate 7 is made so that the angle between the front end surface of the flip plate 7 and the lower end surface of the support plate 3 is less than 15 degrees, thereby opening the flip plate 7, which is convenient for vehicles to pass through the device. In the process of the flip plate 7 rising and opening, due to the connection between the one-way locking component and the rotating shaft 13, the rotating shaft 13 is limited to rotate in the forward direction. By the same principle, when the power motor 14 is turned on in the reverse direction, the one-way locking component is adjusted, and the rotating shaft 13 is rotated at this time, so as to facilitate the flip plate 7 to flip and move downward, so that the flip plate 7 is restored to its original state, thereby closing the garage.
