Technical Field
[0001] This invention relates to the field of transfer window technology, and more particularly to a sterilizable transfer window for biological laboratories. Background Technology
[0002] To facilitate the safe disposal of laboratory waste, many laboratories are equipped with pass-through windows for disinfection. However, repeated opening and closing of these windows by laboratory personnel can contaminate the handles and potentially pollute the laboratory environment. Summary of the Invention
[0003] The present invention aims to address the shortcomings of the prior art by providing a sterilizable transfer window for biological laboratories.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a biological laboratory sterilizable transfer window, comprising a rectangular box body, with doors hinged at both ends of the box body, magnetic buckles that cooperate with each other on the inner surface of the doors and the ends of the box body, a sealing ring that seals with the box body on the inner surface of the doors, glass in the middle of the doors, and a handle on the opposite side of the hinged edge of the doors. The handle is an inverted "L" shape, with the horizontal part of the handle fixed to the door and the vertical part facing downwards. A handle sterilization mechanism is provided below the handle. The handle sterilization mechanism includes a tank body, with a pressing plate inside the tank body, a sealing ring that seals with the side wall of the tank body on the outer periphery of the pressing plate, a perforation on the bottom surface of the tank body, a tank cover on the top surface, a pressing cylinder below the tank body, the cylinder rod of the pressing cylinder passing through the perforation and fixed to the pressing plate, multiple spray holes on the tank cover, the tank cover being hinged to the tank body, and both the tank body and the pressing cylinder being fixed to the doors.
[0005] Preferably, a sealing cap is provided above the can lid, and a sealing ring is provided on the lower surface of the sealing cap to seal with the can lid, and the sealing cap is hinged to the can lid.
[0006] Preferably, it further includes a switching mechanism for driving the can lid switch and driving the cap to move relative to the can lid.
[0007] Preferably, the switching mechanism includes a vertical control shaft driven by a motor, disposed on one side of the tank body, a polygonal-shaped locking block fixedly sleeved on the upper part of the control shaft, vertical rotating rings connected to one side of the tank lid and the other side of the sealing lid, the inner wall of the rotating ring having a polygonal cross-section that matches the locking block, the locking block passing through the rotating ring, the length of the locking block being greater than the distance between the two rotating rings, and a lifting mechanism for driving the motor to lift.
[0008] Preferably, the lifting mechanism includes an "L"-shaped connecting rod located below the motor. The upper end of the connecting rod is fixedly connected to the motor housing, and the lower end is provided with a horizontal limiting plate. A through hole is provided on the limiting plate, through which the cylinder rod of the extrusion cylinder passes. A retaining ring is fixedly sleeved on the cylinder rod of the extrusion cylinder. The outer diameter of the retaining ring is smaller than the diameter of the through hole but larger than the diameter of the through hole. The retaining ring is located above the through hole. A spring is sleeved on the vertical part of the connecting rod. The upper end of the spring is fixedly connected to the motor, and the lower end is fixedly connected to the tank body. When the retaining block intersects with the rotating ring of the tank cover, the spring is in a compressed state. When the extrusion plate moves to fit against the lower end of the tank body, the retaining ring fits against the limiting plate, and the retaining block intersects with both rotating rings. When the retaining ring disengages from the limiting plate, the retaining block intersects with the rotating ring of the sealing cap but not with the rotating ring of the tank cover.
[0009] The beneficial effects of this invention are: by setting a container for disinfectant under the handle, the handle is disinfected in real time under the action of the squeezing plate, thus reducing the chance of contamination. Attached Figure Description

[0015] The following will describe in detail, with reference to the accompanying drawings, embodiments of the present invention. Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0017] like Figure 1 and Figure 2As shown, the present invention includes a rectangular box 1, with boxes 2 hinged at both ends of the box 1. Magnetic snaps that cooperate with each other are provided on the inner surface of the boxes 2 and the ends of the box 1. A sealing ring that seals with the box 1 is provided on the inner surface of the boxes 2. A glass 3 is provided in the middle of the boxes 2. A handle 4 is provided on the opposite side of the hinged edge of the boxes 2. The handle 4 is an inverted "L" shape, with its horizontal part fixed to the boxes 2 and its vertical part facing downwards. A handle disinfection mechanism 5 is provided below the handle 4. The handle disinfection mechanism 5 includes a container. The tank body 5-1 has an extrusion plate 5-2 inside it. A sealing ring is provided on the outer periphery of the extrusion plate 5-2 to seal the side wall of the tank body 5-1. A perforation 5-13 is opened on the bottom surface of the tank body 5-1, and a tank cover 5-4 is provided on the top surface. An extrusion cylinder 5-5 is provided below the tank body 5-1. The cylinder rod of the extrusion cylinder 5-5 passes through the perforation 5-13 and is fixedly connected to the extrusion plate 5-2. Multiple spray holes are opened on the tank cover 5-4. The tank cover 5-4 is hinged to the tank body 5-1. Both the tank body 5-1 and the extrusion cylinder 5-5 are fixedly connected to the door 2.
[0018] The present invention has a transfer window with a container 5-1 for storing disinfectant liquid below the handle 4 which is easily contaminated. The lid 5-4 of the container 5-1 can be opened and closed and can spray disinfectant liquid. The lifting and lowering of the squeezing plate 5-2 is controlled by the squeezing cylinder 5-5. When the disinfectant liquid in the container 5-1 is squeezed by the squeezing plate 5-2, the liquid is sprayed out from the spray hole of the lid 5-4. The container 5-1 is directly opposite the handle 4, and the handle 4 is an inverted "L" shape, which facilitates the thorough disinfection of the handle 4 and reduces the possibility of disinfection dead corners.
[0019] The present invention takes into account that the disinfectant liquid in the tank 5-1 may be volatile. Therefore, a cap 5-3 is provided above the tank cover 5-4, and a sealing ring is provided on the lower surface of the cap 5-3 to seal with the tank cover 5-4. The cap 5-3 and the tank cover 5-4 are hinged together.
[0020] like Figure 3 and Figure 4As shown, to prevent contamination of the tank body 5-1 by the opening and closing of the disinfectant container and the cap 5-3, a switching mechanism is also included to drive the opening and closing of the cap 5-4 and to drive the cap 5-3 to move relative to the cap 5-4. The switching mechanism includes a vertical control shaft 5-9 driven by a motor 5-10 on one side of the tank body 5-1. A polygonal locking block 5-8 is fixedly sleeved on the upper part of the control shaft 5-9. Vertical rotating rings 5-7 are connected to both one side of the cap 5-4 and one side of the cap 5-3. The inner wall of the rotating ring 5-7 has a polygonal cross-section that matches the locking block 5-8. The locking block 5-8 passes through the rotating ring 5-7, and the length of the locking block 5-8 is greater than the distance between the two rotating rings 5-7. The mechanism also includes a lifting mechanism for driving the motor 5-10 to move up and down. The lifting mechanism includes an "L"-shaped connecting rod 5-12 located below the motor 5-10. The upper end of the connecting rod 5-12 is fixed to the housing of the motor 5-10, and the lower end is provided with a horizontal limit. Position plate 5-14 has a through hole 5-15. The cylinder rod of extrusion cylinder 5-5 passes through the through hole 5-15. A retaining ring 5-6 is fixedly sleeved on the cylinder rod of extrusion cylinder 5-5. The outer diameter of retaining ring 5-6 is smaller than the diameter of through hole 5-13 but larger than the diameter of through hole 5-15. Retaining ring 5-6 is located above through hole 5-15. A spring 5-11 is sleeved on the vertical part of connecting rod 5-12. The upper end of spring 5-11 is connected to motor 5-10. The lower end is fixed to the tank body 5-1. When the locking block 5-8 intersects with the rotating ring 5-7 of the tank cover 5-4, the spring 5-11 is in a compressed state. When the pressing plate 5-2 moves to fit with the lower end of the tank body 5-1, the locking ring 5-6 fits with the limiting plate 5-14 and the locking block 5-8 intersects with both rotating rings 5-7. When the locking ring 5-6 disengages from the limiting plate 5-14, the locking block 5-8 intersects with the rotating ring 5-7 of the sealing cover 5-3 but does not intersect with the rotating ring 5-7 of the tank cover 5-4.
[0021] Under normal circumstances, under the action of spring 5-11, the locking block 5-8 is located inside the rotating ring 5-7 of the cap 5-3. The motor 5-10 drives the opening and closing of the cap 5-3. The lifting and lowering of the squeezing plate 5-2 has no effect on the limiting plate 5-14. When it is necessary to inject disinfectant into the tank 1, the squeezing plate 5-2 is moved to the lower end of the tank 1 to provide space for the injection and outflow of disinfectant. At this time, the locking ring 5-6 is in contact with the limiting plate 5-14 and moves down a certain distance, driving the locking block 5-8 into the rotating ring 5-7 of the cap 5-4. The motor 5-10 simultaneously drives the cap 5-4 and the cap 5-3 to open and close together.
[0022] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other occasions without modification, are all within the protection scope of the present invention.
