Description

Technical Field

[0001] This invention belongs to the field of security gate technology, and in particular relates to a security gate with automatic disinfection and cleaning. Background Technology

[0002] A security gate is a detection device used to check whether people are carrying metal objects; it is also known as a metal detector. Metal detector security gates are mainly used in public places with high traffic, such as airports, train stations, and large conferences, to check for metal objects concealed on people's bodies.

[0003] Existing security gates, under prolonged use and high traffic volume, easily accumulate dust and germs. For example, Chinese utility model CN218816063U discloses a security gate that is easy to clean. A dual-axis motor drives a lead screw to rotate, causing the lead screw to move a long strip up and down, which in turn drives a brush to clean the main body of the security gate.

[0004] However, in the above-mentioned technical solutions, the brush can only move up and down, resulting in poor cleaning effect. It is difficult to completely remove stains and water stains, leading to poor cleaning results. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic disinfection and cleaning security gate. The cleaning mechanism drives the cleaning roller to move up and down, and the cleaning roller rotates to clean the security gate body, thus solving the problem of poor cleaning effect of existing security gates.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to an automatic disinfection and cleaning security gate, comprising two gate bodies, each rotatably connected to two lead screws, and a drive device fixedly connected to the lead screws; a rack is fixedly connected to one side of each gate body; both lead screws are fitted with nuts, and a cleaning mechanism is fixedly connected between the two nuts; the cleaning mechanism includes end plates respectively connected to the two nuts, side plates fixedly connected to the sides of each end plate, and the side plates are connected by a fixed plate, forming a U-shaped structure around the gate body, and a spray pipe is fixedly connected to the fixed plate; one end plate is rotatably connected to a drive gear meshing with the rack; a cleaning roller is rotatably connected between the side plates, and one end of the cleaning roller is driven by the drive gear, used to drive the cleaning mechanism up and down through the nuts, causing the cleaning roller to rotate and clean the surface of the security gate body.

[0008] As a preferred embodiment of the present invention, the lead screw is located inside the security gate body, the end plate penetrates through the side wall of the security gate body, and the upper ends of the two lead screws are connected in a transmission manner, wherein one lead screw is connected in a transmission manner to the driving device.

[0009] As a preferred embodiment of the present invention, the end plate is rotatably connected to a drive shaft, one end of which is connected to a driven gear meshing with the driving gear, and the other end is connected to the rotating shaft of the cleaning roller.

[0010] As a preferred embodiment of the present invention, the transmission ratio between the driving gear and the driven gear is greater than 1.

[0011] As a preferred embodiment of the present invention, both side plates are connected to mounting bases, and the rotating shafts at both ends of the sweeping roller are rotatably connected to the mounting bases respectively; one of the mounting bases is rotatably connected to a connecting shaft, one end of which is connected to the rotating shaft of the sweeping roller, and the other end is connected to a transmission shaft.

[0012] As a preferred embodiment of the present invention, the mounting base is slidably connected to the side plate, one end of the transmission shaft is a spline shaft structure, and the other end of the connecting shaft is a spline sleeve structure that mates with it; the mounting base is connected to a telescopic device, which is used to drive the mounting base to move through the telescopic device and adjust the distance between the cleaning roller and the surface of the security gate.

[0013] As a preferred embodiment of the present invention, a spring is fixedly connected between the mounting base and the fixing plate.

[0014] In a preferred embodiment of the present invention, the connecting shaft is connected to a worm gear, and the rotating shaft of the cleaning roller is connected to a worm wheel that meshes with the worm gear.

[0015] As a preferred embodiment of the present invention, when the cleaning mechanism moves from top to bottom, the cleaning roller contacts the surface of the security gate, and the linear velocity direction of the side of the cleaning roller in contact with the security gate is the same as the moving direction of the cleaning roller.

[0016] As a preferred embodiment of the present invention, when the cleaning mechanism moves from bottom to top, the cleaning roller does not come into contact with the security gate.

[0017] The present invention has the following beneficial effects:

[0018] This invention uses a lead screw to drive the cleaning mechanism to move up and down, and through the meshing of a drive gear and a rack, the cleaning mechanism drives the cleaning roller to move up and down while simultaneously rotating the cleaning roller. This allows the cleaning roller to clean the surface of the security gate. The rotation of the cleaning roller makes the removal of dirt and water stains on the surface of the security gate more thorough, thereby effectively improving the overall cleaning effect.

[0019] At the same time, disinfectant is sprayed through the fixed plate spray pipe, and the surface of the security gate is disinfected by the movement of the cleaning mechanism, thereby further improving the cleanliness of the security gate surface.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0035] Example 1

[0036] Please see Figure 1 and 2 As shown, the present invention is an automatic disinfection and cleaning security gate, comprising two security gate bodies 1, each security gate body 1 being rotatably connected to two vertically arranged lead screws 101, and a drive device 102 fixedly connected to the lead screws 101. A groove is provided on one side of the security gate body 1, and a rack 103 is fixedly connected in the groove. The rack 103 is arranged parallel to the lead screws 101.

[0037] like Figure 3 As shown, the lead screw 101 is located inside the security gate body 1. The side of the security gate body 1 has a slot corresponding to the position of the lead screw 101. The upper ends of the two lead screws 101 are connected by a synchronous belt or chain. One of the lead screws 101 is connected to the drive device 102. The drive device 102 is a motor, so that the two lead screws 101 can be driven to rotate synchronously by one motor.

[0038] like Figure 4 and 5 As shown, both lead screws 101 are fitted with lead nuts 107, and a cleaning mechanism 2 is fixedly connected between the two lead nuts 107. The cleaning mechanism 2 includes end plates 201 that are respectively connected to the two lead nuts 107. The end plates 201 penetrate the side wall of the security gate body 1 through slots. Side plates 202 are fixedly connected to the sides of the two end plates 201, and the two side plates 202 are connected by a fixing plate 203, so that the two side plates 202 and the fixing plate 203 form a U-shaped structure around the security gate body 1. The fixing plate 203 is fixedly connected to a spray pipe 4 by a ferrule. The spray pipe 4 is connected to a pump body through a hose, and is used to inject disinfectant into the spray pipe 4 through the pump body and spray it out in an atomized form, thereby achieving spray disinfection of the surface of the security gate body 1.

[0039] like Figures 6-9 As shown, one end plate 201 is rotatably connected to a drive gear 104 that meshes with a rack 103; a cleaning roller 3 is rotatably connected between the two side plates 202, and one end of the cleaning roller 3 is connected to the drive gear 104 for transmission.

[0040] The end plate 201 is rotatably connected to a drive shaft 105, one end of which is connected to a driven gear 106 meshing with a drive gear 104, and the other end is connected to the rotating shaft of the cleaning roller 3. Furthermore, both side plates 202 are connected to mounting bases 5, and the rotating shafts at both ends of the cleaning roller 3 are rotatably connected to the mounting bases 5 respectively.

[0041] Specifically, one of the mounting bases 5 is rotatably connected to a connecting shaft 501. One end of the connecting shaft 501 is connected to the rotating shaft of the sweeping roller 3, and the other end is connected to the transmission shaft 105. For example, a worm gear 504 is connected through the connecting shaft 501, and a worm wheel 505 that meshes with the worm gear 504 is connected to the rotating shaft of the sweeping roller 3. Through the meshing of the worm wheel 505 and the worm gear 504, the connecting shaft 501 drives the sweeping roller 3 to rotate.

[0042] During cleaning, the drive device 102 drives the two lead screws 101 to rotate, causing the lead screw nut 107 to drive the cleaning mechanism 2 to move up and down. During the movement, the drive gear 104 meshes with the rack 103, causing the drive gear 104 to drive the driven gear 106 to rotate, which in turn drives the cleaning roller 3 to rotate through the connecting shaft 501. Thus, the up and down movement of the cleaning mechanism 2 causes the cleaning roller 3 to rotate, and the cleaning mechanism 2 drives the cleaning roller 3 to move up and down, thereby cleaning the surface of the security gate 1. The rotation of the cleaning roller 3 makes the dirt and water stains on the surface of the security gate 1 more thoroughly cleaned, thus effectively improving the overall cleaning effect.

[0043] Meanwhile, the transmission ratio between the driving gear 104 and the driven gear 106 is greater than 1, which increases the rotational speed of the driven gear 106, thereby enabling the cleaning roller 3 to achieve a higher rotational speed, which is beneficial to improving the cleaning effect.

[0044] Example 2

[0045] Based on Example 1, such as Figure 4 and 8 As shown, the side plate 202 has a U-shaped cross-section. The mounting base 5 is slidably connected to the side plate 202. One end of the drive shaft 105 is a spline shaft structure, and one end of the connecting shaft 501 is a spline sleeve structure that mates with it. This allows the drive shaft 105 and the connecting shaft 501 to transmit power and move axially.

[0046] The mounting base 5 is connected to a telescopic device 502, which can be an electric cylinder or an electric push rod. The other end of the telescopic device 502 can be connected to the fixed plate 203 or the side plate 202. It is used to move the mounting base 5 through the telescopic device 502 to adjust the distance between the cleaning roller 3 and the surface of the security gate 1, so that the cleaning roller 3 can maintain good contact with the surface of the security gate 1, which is conducive to ensuring the cleaning effect.

[0047] Example 3

[0048] Based on Embodiment 2, a spring 503 is fixedly connected between the mounting base 5 and the fixing plate 203. By adding the spring 503, the gap between the components can be eliminated, making the movement of the mounting base 5 more stable.

[0049] Furthermore, when the cleaning mechanism 2 moves from top to bottom, the cleaning roller 3 contacts the surface of the security gate 1, and the linear velocity direction of the side of the cleaning roller 3 in contact with the security gate 1 is the same as the moving direction of the cleaning roller 3. That is, when the cleaning roller 3 moves downward, the rotation of the cleaning roller 3 itself will also sweep the stains and foreign objects on the surface of the security gate 1 downward, thereby improving the cleaning effect.

[0050] At the same time, when the cleaning mechanism 2 moves from bottom to top, the telescopic device 502 pulls the mounting base 5, causing the cleaning roller 3 to move away from the security gate body 1, so that the cleaning roller 3 does not contact the security gate body 1. At this time, when the lead screw 101 drives the cleaning mechanism 2 to move upward and reset, the cleaning roller 3 does not contact the security gate body 1, thereby avoiding the situation where the cleaning roller 3 flips over and easily brings foreign objects into the surface of the security gate body 1, so that each cleaning is from top to bottom, thus ensuring the cleaning effect.

[0051] In addition, the spray pipe 4 can spray disinfection when the cleaning roller 3 moves upward. On the one hand, it can disinfect the surface of the security gate 1 after cleaning, which can improve the disinfection effect. On the other hand, it can avoid the situation where the disinfectant is easily washed away during the cleaning process of the cleaning roller 3, which would affect the disinfection effect. Therefore, disinfection during the upward movement and reset of the cleaning roller 3 can effectively improve the disinfection effect on the surface of the security gate 1.
