DETAILED DESCRIPTION

[0025] In order to further understand the utility model content, characteristics and efficacy of the utility model, the following examples are cited, and the drawings are described in detail as follows.

[0026] As Figures 1 to 6 The utility model discloses a kind of automatic wiping disinfecting door handle structures provided in the embodiment, including door panel 1, door panel 1 is provided with handle rotating shaft 2, handle rotating shaft 2 is provided with door handle 3, door panel 1 is fixedly installed with the frame 4 located at the outside of handle rotating shaft 2, the top of frame 4 is fixedly installed with liquid storage box 5, the bottom of liquid storage box 5 is fixedly communicated with elastic hose 30, the other end of elastic hose 30 is fixedly connected with square box 31, square box 31 is fixedly sleeved on door handle 3, the right side of square box 31 is provided with pressing liquid outlet end 32, the outer surface of door handle 3 is movably sleeved with sponge ring 6, rack 7 is movably installed in the inner wall bottom of frame 4, bottom hole 8 is set on rack 7 bottom in frame 4, sponge ring 6 and rack 7 are connected by telescopic component between, rack 7 and handle rotating shaft 2 are connected by transmission component between, rack 7 and frame 4 are also connected by elastic component.

[0027] Further, the transmission assembly comprises a missing tooth gear 9 fixedly installed on the handle rotating shaft 2, a circular shaft 10 rotatably connected to the frame 4, a first gear 11 and a second gear 12 fixedly sleeved on the outer surface of the circular shaft 10, the first gear 11 is in meshing connection with the missing tooth gear 9, and the rack 7 is connected with the second gear 12 through the gear assembly.

[0028] When a person presses the door handle 3 to open the door, the handle rotating shaft 2 and the missing tooth gear 9 are driven to rotate, so that the missing tooth gear 9 drives the circular shaft 10 and the second gear 12 to rotate together.

[0029] Further, the gear assembly comprises a first fixed gear 13 and a second fixed gear 14, both of which are rotatably connected to the frame 4, the first fixed gear 13 is in meshing connection with the second gear 12, the second fixed gear 14 is in meshing connection with the rack 7, a through hole 15 is formed in the frame 4, a rotating shaft 16 is movably installed in the through hole 15, a driving shaft gear 17 is fixedly sleeved on the rotating shaft 16, and the driving shaft gear 17 is in meshing connection between the first fixed gear 13 and the second fixed gear 14.

[0030] When a person presses the door handle 3 to open the door and drives the second gear 12 to rotate, the first fixed gear 13, the driving shaft gear 17 and the second fixed gear 14 are driven to rotate together. Due to the rotation of the second fixed gear 14, the rack 7 moves to the left. Since the driving shaft gear 17 is movably installed in the through hole 15 through the rotating shaft 16, and the through hole 15 is arranged in an inclined manner, when the driving shaft gear 17 needs to transmit power by rotating, under the rotating action of the first fixed gear 13 and the second fixed gear 14, the driving shaft gear 17 maintains the meshing state with the first fixed gear 13 and the second fixed gear 14, so that the rotating shaft 16 is kept at the bottom of the through hole 15 cavity. When the subsequent rack 7 moves to the right without transmitting power by rotating the driving shaft gear 17, under the rotating action of the first fixed gear 13 or the second fixed gear 14, the driving shaft gear 17 drives the rotating shaft 16 to move obliquely upward along the inner wall of the through hole 15, so that the driving shaft gear 17 temporarily separates from the meshing state with the first fixed gear 13 and the second fixed gear 14. After the subsequent rack 7 returns to the original position, the driving shaft gear 17 drives the rotating shaft 16 to move obliquely downward along the inner wall of the through hole 15 to return to the original position under the action of gravity, and the meshing state with the first fixed gear 13 and the second fixed gear 14 is restored.

[0031] Further, the telescopic assembly comprises a telescopic rod 18 fixedly installed at the bottom of the rack 7, the telescopic end of the telescopic rod 18 extends to the lower side of the frame 4 through the bottom hole 8, the telescopic end of the telescopic rod 18 is hingedly connected with a connecting rod 19, and the sponge ring 6 is arranged on the connecting rod 19.

[0032] When the rack 7 moves to the left, the sponge ring 6 can be driven to move to the left through the telescopic rod 18 and the connecting rod 19, so that the sponge ring 6 can contact and press the liquid outlet end 32 to obtain the disinfectant.

[0033] Further, the outer surface of the sponge ring 6 is sleeved with a check ring 20, and the check ring 20 is hinged between the connecting rod 19.

[0034] Through the design of the check ring 20, the contact area of the disinfectant on the sponge ring 6 with air can be reduced, so that the volatilization of the disinfectant is reduced under the premise of ensuring the disinfection effect, and the waste of the disinfectant is reduced.

[0035] Further, the elastic assembly comprises a square plate 21 fixedly installed on the inner wall of the frame 4, the square plate 21 is fixedly connected with a return spring 22, and the other end of the return spring 22 is fixedly connected to the rack 7.

[0036] Further, the inner wall of the frame 4 is fixedly installed with a cylinder 23 located to the left of the rack 7, the left end of the rack 7 is fixedly installed with a circular ring 25, the left side of the inner wall of the cylinder 23 is fixedly connected with a first spring 24, and the other end of the first spring 24 is fixedly connected to the circular ring 25.

[0037] Through the setting of the first spring 24 and the return spring 22 as a normal state, when the rack 7 moves to the left, the first spring 24 and the return spring 22 can be compressed, so that the elastic force can be stored, and the subsequent rack 7 drives the sponge ring 6 to move to the right to wipe the door handle 3.

[0038] Further, the inner wall of the frame 4 is rotatably connected with a buckle 26 located below the circular ring 25, the inner wall of the frame 4 is fixedly installed with a bottom plate 27 located below the buckle 26, the buckle 26 and the bottom plate 27 are fixedly connected with a second spring 28, the top of the handle shaft 2 is fixedly installed with a flange 29, and the flange 29 abuts against the bottom of the buckle 26.

[0039] When people rotate the door handle 3, the handle shaft 2 drives the flange 29 to rotate, at this time, due to the elastic force of the second spring 28, the left end of the buckle 26 is upwardly rotated, and when the rack 7 drives the circular ring 25 to compress the first spring 24 to move to the left, the left end of the buckle 26 can clamp the circular ring 25 to store the elastic energy of the first spring 24, so that when the handle shaft 2 drives the flange 29 to rotate to return to the original position, the buckle 26 can be released from the limiting of the circular ring 25, and then the rack 7 drives the sponge ring 6 to move to the right to wipe the door handle 3 for disinfection under the elastic force of the first spring 24.
