[0002] In the field of biosafety protection, ultraviolet disinfection is widely used in the disinfection process of biosafety cabinets due to its high efficiency and residue-free characteristics. The disinfection effect of ultraviolet disinfection lamps is closely related to the distance between them and the items to be disinfected. Different types and sizes of items have different requirements for the disinfection distance.

[0003] Currently, most biosafety cabinets on the market use fixed installations for their ultraviolet (UV) disinfection lamps. Once the position is determined, it cannot be adjusted. When dealing with different items to be disinfected, it is impossible to flexibly adjust the distance between the UV lamp and the items according to actual needs. If the distance is too large, the intensity of UV radiation will be weakened, making it difficult to achieve the ideal disinfection effect. This may result in some items not being thoroughly disinfected, posing a biosafety hazard. If the distance is too small, on the one hand, the UV radiation may be too concentrated, causing damage to some sensitive items. On the other hand, the items may block the light, resulting in insufficient disinfection of the surrounding area. Utility Model Content

[0023] Furthermore, the spring 63 ensures tight contact and reliable fixation between the card plate 62 and the card slot 61, making operation simple and convenient, and effectively improving the stability and safety of the entire device.

[0024] Please see Figure 1-4 An expansion panel 7 is fixedly connected to the top rear side of the card plate 62, and the expansion panel 7 is located on top of the spring 63.

[0025] Furthermore, by adding panel 7, the contact area between the operator and the pallet 62 can be increased, making it easier and more convenient to adjust the position of the pallet 62, thus improving the ease of operation. Especially in the case of frequent adjustments, it can effectively reduce operator fatigue and improve work efficiency.

[0026] Please see Figure 1-4 A stabilizing frame 8 is fitted on the top of the surface of the winding wheel 5, and the bottom of the stabilizing frame 8 is fixedly connected to the top of the biosafety cabinet body 1.

[0027] Furthermore, by setting the stabilizer 8, the radial sway of the winding wheel 5 during rotation can be effectively limited, ensuring that the winding wheel 5 is always in a stable working state. This ensures that the winding and unwinding process of the pull rope 4 is smooth and orderly, avoiding problems such as the pull rope 4 getting tangled, worn, or the lifting plate 2 tilting due to the sway of the winding wheel 5. This extends the service life of the device and enhances the stability of the overall structure.

[0028] Please see Figure 1-4 A handle 9 is fixedly connected to the top of the reel 5, and the handle 9 is located on the top of the biosafety cabinet body 1.

[0033] Furthermore, by setting the reinforcing block 11, the firmness of the connection between the pull rope 4 and the lifting plate 2 can be enhanced. By increasing the contact area of ​​the connection part, the tension of the pull rope 4 on the top of the lifting plate 2 is dispersed, avoiding the problem of damage to the connection point at the top of the lifting plate 2 due to long-term stress on the pull rope 4. This ensures that the pull rope 4 can stably drive the lifting plate 2 to rise and fall, improves the load-bearing capacity and reliability of the entire connection structure, and ensures the safe and stable operation of the device.

[0034] The specific implementation process of this utility model is as follows: When in use, first place the items inside the biosafety cabinet body 1, turn on the ultraviolet disinfection lamp 3, different items need different distances from the ultraviolet disinfection lamp 3, and adjust the height of the ultraviolet disinfection lamp 3.

[0035] Push the back of the card plate 62 downwards to flip it over, compressing the spring 63 on the back of the card plate 62. The front of the card plate 62 flips upwards, separating the card slot 61 on the front of the card plate 62. The winding wheel 5 loses its positioning effect. Rotate the handle 9, which drives the winding wheel 5 to rotate. The winding wheel 5 unwinds the pull rope 4, and the bottom of the pull rope 4 gradually descends. The lifting plate 2 and the ultraviolet disinfection lamp 3 also descend accordingly. When the ultraviolet disinfection lamp 3 is adjusted to a suitable distance from the item, stop rotating the winding wheel 5 and reset the card plate 62.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
