Description

Technical Field

[0001] This utility model relates to the field of trolley technology, specifically a novel multifunctional automatic sterilization trolley for barrier applications. Background Technology

[0002] A handcart is a transport vehicle that is pushed and pulled by human power. It is the ancestor of all vehicles. Although the material handling technology of handcarts has been continuously developed, handcarts are still used as an indispensable transport tool. Handcarts are widely used in production and daily life because they are inexpensive, easy to maintain, convenient to operate, and lightweight. They can work in places where motor vehicles are inconvenient to use and are very convenient for transporting lighter items over short distances.

[0003] Existing SPF-grade laboratories have different usage needs for each laboratory, requiring staff to move between different experimental breeding rooms over a period of time. When the trolleys enter different experimental rooms, the wheels come into contact with the ground, posing a serious biosafety hazard. Currently, before pushing the trolleys into different rooms, staff use a disinfectant sprayer to spray the wheels for disinfection. However, the spraying is not thorough and the method is inconvenient. Utility Model Content

[0022] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0023] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0024] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a novel multifunctional automatic sterilization trolley for barrier applications.

[0025] Example 1:

[0026] Combination Figure 1-Figure 5 As shown, this utility model provides a novel multifunctional automatic sterilization trolley for barrier applications, comprising a frame 1, a push frame 3 fixed to one side of the frame 1, and four symmetrically arranged connecting seats a21 fixed to the bottom side of the frame 1. Connecting seats b22 are rotatably connected to the connecting seats a21, and the connecting seats a21 and b22 are fixed with bolts. A universal wheel 23 is fixed to the bottom side of the connecting seat b22, and a roller 24 is fixed to the bottom side of the universal wheel 23. The bottom side of the universal wheel 23 is located at the roller 24. A mounting cover 25 is fixed to the upper end of the 4. Multiple symmetrically arranged brushes 26 are fixed to the inner wall of the mounting cover 25. The mounting cover 25 is suspended and fitted onto the upper outer wall of the roller 24. The contact surfaces of the brushes 26 and the wheel are in contact with each other. Multiple symmetrically arranged support platforms 9 are fixed to the bottom side of the frame 1. A mounting frame 51 is fixed to the two adjacent side walls of the push frame 3. Two symmetrically arranged guide rails 52 are fixed to one side wall of the mounting frame 51. The outer walls of the two guide rails 52 slide together. A liquid tank 53 is connected to the liquid tank 53 via a hinge. A cover plate 59 is rotatably connected to the top side of the liquid tank 53. A handle 510 is fixed to one side of the liquid tank 53. A connecting pipe 54 is connected to the bottom side of the liquid tank 53. A threaded groove 55 is opened on the outer side wall of the connecting pipe 54. A round hole 56 is opened on the bottom side of the mounting frame 51. A locking nut 57 is threadedly engaged with the bottom end of the connecting pipe 54 through the round hole 56. A flow controller 58 is threadedly connected to the outer side wall of the connecting pipe 54. The bottom end of the conveying pipe 4 is connected to the top end of the conveying pipe 4. Multiple symmetrically arranged lifting frames 8 are fastened to the outer wall of the conveying pipe 4. The top side of the lifting frame 8 is fixedly connected to the bottom side of the frame 1. The end of the conveying pipe 4 away from the flow controller 58 is connected to the main pipe 71. Both ends of the main pipe 71 are connected to the output pipe 72. Both ends of the output pipe 72 are fixed with atomizing nozzles 73. The atomizing nozzles 73 are located in the cavity on one side of the mounting cover 25 and are located at the upper end of the roller 24.

[0027] The working principle and usage process of this utility model are as follows: When it is necessary to disinfect the wheels, firstly, the flow controller 58 is activated. Then, the disinfectant flows through the liquid tank 53 into the connecting pipe 54, and then through the connecting pipe 54 into the flow controller 58. The disinfectant is pressurized by the flow controller 58 and discharged into the delivery pipe 4. Through the delivery pipe 4, the disinfectant is discharged into the main pipe 71. In the main pipe, the disinfectant is pressurized by the flow controller 58 and then flows into the output pipe 72. Finally, it is sprayed onto the roller 24 through the atomizing nozzles 73 connected at both ends of the output pipe 72. Then, the pusher 3 is pushed, and the pusher 3 simultaneously moves the frame 1 and the wheel assembly 2. When the roller 24 rotates, it can be disinfected around its circumference. At the same time, the surface of the roller 24 is in contact with the mounting cover. When the brush 26 inside 25 contacts and rubs, it completes the disinfection of one circle of roller 24. When it is necessary to disassemble and clean roller 24, first start the four support platforms 9. When the bottom of the support platform 9 contacts the ground, the bottom of the support platform 9 continues to rise until the four rollers 24 leave the ground. Then stop the operation of the support platform 9, then unscrew the bolts connecting the connecting seat a21 and the connecting seat b22, and then remove the wheels. Then the rollers 24 and the mounting cover 25 can be cleaned. When it is necessary to clean the liquid tank 53, first unscrew the flow controller 58 from the outer wall of the connecting pipe 54, then unscrew the locking nut 57, and then lift the handle 510 upward to move the liquid tank 53 upward on the outer wall of the guide rail 52 until the liquid tank 53 is separated from the pipe. Then the liquid tank 53 can be cleaned.

[0028] It should be noted that the liquid storage component 5, the pipeline, and the delivery pipe 4 allow for continuous disinfection and cleaning of the roller 24, thus preventing cross-contamination of organisms when the roller 24 enters different rooms and effectively improving the disinfection effect of the roller 24. The support platform 9 makes it easier to lift the trolley, facilitating the disassembly, cleaning, or replacement of the wheel assembly 2. The mounting cover 25 and brush 26 further enhance the disinfection effect of the roller 24. The connecting seats a21 and b22 are secured with bolts, allowing for convenient disassembly, replacement, or cleaning of the wheel assembly 2. The mounting frame 51 and guide rail 52 improve the efficiency of the liquid tank 53 during entry. The installation frame is designed to facilitate easy installation and effectively limit the installation position of the liquid tank 53. The connecting pipe 54, threaded groove 55, and locking nut further enhance the firmness of the liquid tank 53. The flow controller 58 can control the flow rate of the liquid according to the disinfection requirements of each laboratory, thereby achieving the disinfection requirements of the roller 24. The cover plate 59 can effectively prevent the disinfectant from splashing out of the liquid tank 53. The handle 510 makes it easier to remove the liquid tank 53 from the installation frame 51. The atomizing nozzle 73 can further improve the disinfection effect of the roller 24 and effectively prevent liquid accumulation on the ground due to excessive flow. The lifting frame 8 can effectively prevent the delivery pipe 4 from getting tangled due to the pipe being suspended.
