Description

Technical Field

[0001] This invention relates to the field of aseptic operating box technology, specifically a side-extending foldable aseptic operating box. Background Technology

[0002] The sterile operating box, also known as the plexiglass vacuum sterile operating box, is made of highly transparent colorless plexiglass. It is mainly used to conduct scientific experiments that isolate substances that are easily oxidized and deliquesced in atmospheric conditions from the air. It has a simple structure, is easy to use, has stable shape, is highly transparent, is resistant to chemical corrosion and climate change, and has good sealing performance. It can also shield and absorb alpha rays and low-energy beta rays emitted by radioactive materials.

[0003] Aseptic operation boxes come in various models. Based on their size, they can be divided into large, medium, and small aseptic operation boxes. Small aseptic operation boxes are commonly used in universities for experimental teaching.

[0004] The sterile operation box used for undergraduate teaching is generally 50*50 cm in size, which takes up a lot of space on the table, making it very inconvenient to conduct teaching operations and difficult to store or carry. Therefore, it does not meet the existing needs. To address this, we propose a side-extending foldable sterile operation box. Summary of the Invention

[0005] The purpose of this invention is to provide a side-extending foldable sterile operating box to solve the problems mentioned in the background art, such as the sterile operating box for undergraduate teaching generally having a volume of 50*50, which takes up a lot of space on the table, making it very inconvenient to carry out teaching operations, and also inconvenient to store or carry.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a side-extending foldable aseptic operating box, comprising an operating box body, telescopic sealing bellows fixed at both ends of the operating box body, a sealing end plate fixed at one end of the telescopic sealing bellows, an operating glove installed in the middle of the sealing end plate, a glove sealing ring fixed at the connection between the operating glove and the sealing end plate, and telescopic modules installed at both the front and rear of the telescopic sealing bellows.

[0007] The telescopic module includes four rotating links. A rotating connecting plate connects two adjacent rotating links. Positioning pins are fixed through both ends of each rotating link. The rotating links are rotatably connected to the main body of the operating box, the sealing end plate, or the rotating connecting plate via positioning pins. A fixing block is fixedly installed on each rotating connecting plate. Two rotationally symmetrical sliding connecting blocks are installed between two vertically opposite fixing blocks. A guide hole is opened through one end of each sliding connecting block. A guide link is slidably inserted into the middle of the guide hole. One end of the guide link passes through the guide hole and is fixed to the sliding connecting block. The other end of the guide link is fixed to the fixing block. The surfaces of the two sliding connecting blocks that contact each other are provided with mating grooves and fixed mating blocks. The mating block fixed on one sliding connecting block is inserted into the mating groove on the surface of another sliding connecting block. A limit hole is opened on one side of each mating block. A limit plug is slidably inserted into the inner side of the limit hole. The limit plug is slidably installed in the inner wall of the sliding connecting block. A limit spring is fixed between one end of the limit plug and the inner wall of the sliding connecting block.

[0008] Preferably, the end of the limiting plug facing the docking block is a hemispherical surface, the diameter of the hemispherical surface is the same as the diameter of the limiting plug, and the diameter of the limiting plug is the same as the inner diameter of the limiting hole.

[0009] Preferably, the limiting plug is made of magnetic metal material, and the magnetic attraction force of the magnet to the limiting plug is greater than the elastic force of the limiting spring.

[0010] Preferably, elastic ropes parallel to the guide rod are installed on both sides, and rotating connecting blocks are fixed at both ends of the elastic ropes. Two symmetrically distributed positioning holes are provided on the fixing blocks.

[0011] Preferably, the outer surface of one end of the rotary connecting block and the inner wall of the positioning hole are both provided with threads of the same direction and meshing, and the end of the rotary connecting block is screwed into the positioning hole through the threads.

[0012] Preferably, an air circulation disinfection system is installed on the inner wall of the main body of the control box. The air circulation disinfection system includes an air inlet disinfection box and an air outlet disinfection box, which are symmetrical to each other. An air inlet pipe is fixed to the top of the air inlet disinfection box, and an air outlet pipe is fixed to the top of the air outlet disinfection box. The tops of both the air inlet pipe and the air outlet pipe penetrate the shell of the main body of the control box and their ends are flush with the outer surface of the main body of the control box. An air inlet fan is installed inside the end of the air inlet pipe that is flush with the outer surface of the main body of the control box, and an exhaust fan is installed inside the end of the air outlet pipe that is flush with the outer surface of the main body of the control box.

[0013] Preferably, both the air inlet disinfection box and the air outlet disinfection box have movably installed maintenance doors on their surfaces. The bottom of the air inlet disinfection box has a rectangular array of multiple air inlets, and the bottom of the air outlet disinfection box has a rectangular array of multiple air outlets.

[0014] Preferably, both the air inlet disinfection box and the air outlet disinfection box are equipped with ultraviolet filters. The ultraviolet filter in the air inlet disinfection box draws in air from the air inlet pipe for disinfection and sterilization. The disinfected and sterilized air is discharged into the main body of the operating box through the air inlet. The ultraviolet filter in the air outlet disinfection box disinfects and sterilizes the gas that enters the air outlet disinfection box through the air outlet. The disinfected and sterilized gas is discharged through the air outlet pipe.

[0015] Preferably, a removable filter membrane is installed inside the end of the exhaust pipe where the exhaust fan is installed, and the filter membrane is used to adsorb and filter carbon dioxide.

[0016] Preferably, both the air inlet sterilization box and the air outlet sterilization box are made of opaque plastic shells.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention involves bringing two magnets close to the sliding connecting blocks at the front and rear of the telescopic sealing bellows. Upon approaching the sliding connecting blocks, the magnets magnetically attract the limiting plug inside the sliding connecting blocks, causing the limiting plug to enter the sliding connecting blocks and compress the limiting spring. When the limiting plug enters the sliding connecting blocks and completely disengages from the limiting hole, the connecting block loses its connection with the sliding connecting blocks, allowing the two sliding connecting blocks to separate. At this point, the two elastic ropes between the upper and lower fixed blocks elastically contract due to the loss of connection between the two sliding connecting blocks. The contracting elastic ropes cause the two fixed blocks to move closer together. During this process, the two horizontally rotating connecting rods move closer together until they are parallel and perpendicular to the ground. During this process, the sealing end plate moves closer to the end of the operating box body and compresses the telescopic sealing bellows, achieving the retraction and folding of the aseptic operating box, reducing its space occupation, and facilitating its storage, placement, and transport.

[0019] 2. This invention features slidable limiting plugs installed inside two sliding connecting blocks. These limiting plugs are connected to the inner walls of the sliding connecting blocks using limiting springs. A limiting hole is provided on one side of the mating block. After the mating block is inserted into the mating slot, the limiting plug is first squeezed into the sliding connecting block, compressing the limiting spring. After the mating block is fully inserted into the mating slot, the limiting plug aligns with the limiting hole. At this point, the limiting spring elastically returns to its original position and pushes the limiting plug into the limiting hole. The limiting hole restricts the position of the mating block inserted into the mating slot, ensuring that the mating block and the sliding connecting block are fixed together, preventing the two sliding connecting blocks from separating. This allows the two guide rods to be supported between the two fixed blocks, ensuring that the sealed end plate cannot be reset after unfolding, thus guaranteeing the stability and safety of the aseptic operating box during unfolding and use.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] like Figure 1 , Figure 8 and Figure 9 As shown, a side-extending foldable aseptic operating box includes an operating box body 1. Both ends of the operating box body 1 are fixed with telescopic sealing bellows 7. One end of the telescopic sealing bellows 7 is fixed with a sealing end plate 2. An operating glove 3 is installed in the middle of the sealing end plate 2. A glove sealing ring 4 is fixed at the connection between the operating glove 3 and the sealing end plate 2.

[0032] An air circulation disinfection system 6 is installed on the inner wall of the main body 1 of the control box. The air circulation disinfection system 6 includes an air inlet disinfection box 601 and an air outlet disinfection box 602, which are symmetrical to each other. An air inlet pipe 605 is fixed to the top of the air inlet disinfection box 601, and an air outlet pipe 606 is fixed to the top of the air outlet disinfection box 602. The tops of both the air inlet pipe 605 and the air outlet pipe 606 penetrate the shell of the main body 1 of the control box and their ends are flush with the outer surface of the main body 1 of the control box. An air intake fan is installed inside the end of the air inlet pipe 605 that is flush with the outer surface of the main body 1 of the control box. An air outlet fan is installed inside the end of the air outlet pipe 606 that is flush with the outer surface of the main body 1 of the control box. An exhaust fan is installed inside. Both the air intake disinfection box 601 and the air exhaust disinfection box 602 have movable maintenance doors 607 installed on their surfaces. The bottom of the air intake disinfection box 601 has a rectangular array of multiple air intake holes 603, and the bottom of the air exhaust disinfection box 602 has a rectangular array of multiple air exhaust holes 604. Outside air can be drawn into the main body of the operating box 1 through the air intake fan at the end of the air intake pipe 605 and the air intake holes 603 at the bottom of the air intake disinfection box 601, and the gas in the main body of the operating box 1 can be discharged through the exhaust fan at the end of the air exhaust pipe 606 and the air exhaust holes 604 at the bottom of the air exhaust disinfection box 602, thus realizing gas exchange inside the sterile operating box.

[0033] Both the intake disinfection box 601 and the exhaust disinfection box 602 are equipped with ultraviolet filters. The ultraviolet filter in the intake disinfection box 601 draws in the air through the intake pipe 605 for disinfection and sterilization. The disinfected air is then discharged into the main body 1 of the control box through the intake port 603. The ultraviolet filter in the exhaust disinfection box 602 disinfects the gas that enters the exhaust disinfection box 602 through the exhaust port 604. The disinfected gas is then discharged through the exhaust pipe 606. The end of the exhaust pipe 606, which is equipped with an exhaust fan, has a removable filter membrane installed inside. The filter membrane is used to adsorb and filter carbon dioxide, thus absorbing and filtering the emitted gas to ensure that the emitted gas is odorless and harmless.

[0034] Both the air intake disinfection box 601 and the air exhaust disinfection box 602 are made of opaque plastic shells to ensure that the ultraviolet light emitted by the ultraviolet filter inside the air intake disinfection box 601 and the air exhaust disinfection box 602 will not come into contact with the operator's skin during the process, thus avoiding damage to the operator from ultraviolet rays.

[0035] like Figures 1 to 7As shown, telescopic modules 5 are installed at both the front and rear of the telescopic sealing bellows 7. Each telescopic module 5 includes four rotating connecting rods 501. A rotating connecting piece 503 connects two adjacent rotating connecting rods 501. Positioning pins 502 are fixed through both ends of each rotating connecting rod 501. The rotating connecting rods 501 are rotatably connected to the operating box body 1, the sealing end plate 2, or the rotating connecting piece 503 via positioning pins 502. A fixing block 504 is fixedly installed on the rotating connecting piece 503. Two rotationally symmetrical sliding connecting blocks 509 are installed between two vertically opposite fixing blocks 504. One end of the sliding connecting block 509 has a guide hole 510. A guide rod 506 is slidably inserted into the middle of the guide hole 510. One end of the guide rod 506 passes through the guide hole 510 and is fixed to the sliding connecting block 509. The other end of the guide rod 506 is fixed to the fixing block 504. The surfaces of the two sliding connecting blocks 509 that come into contact with each other have mating grooves 511 and mating blocks 512 that are fixed thereon. The mating blocks 512 fixed on the sliding connecting block 509 are inserted into the mating grooves 511 on the surface of the other sliding connecting block 509. A limit hole 513 is provided on one side of the mating block 512. A limiting plug block 514 is slidably inserted into the inner side of the limiting hole 513. The limiting plug block 514 is slidably installed in the inner wall of the sliding connecting block 509. A limiting spring 515 is fixed between one end of the limiting plug block 514 and the inner wall of the sliding connecting block 509. Pulling the two sealing end plates 2 away from the main body 1 of the operating box causes the telescopic sealing bellows 7 to unfold from the retracted state. When the sealing end plates 2 move, they will drive the two adjacent left and right rotating connecting rods 501 to rotate around the axis of the positioning pin 502. At this time, the two rotating connecting rods 501 will change from a state perpendicular to the ground to a state perpendicular to the water. In the flat state, the sliding connecting block 509 fixed at the end of the guide rod 506 will slide on the outside of another guide rod 506 until the two adjacent rotating rods 501 are horizontal. At this time, the two sliding connecting blocks 509 will contact each other, the docking block 512 will be inserted into the docking slot 511, and the limiting plug 514 will be inserted into the limiting hole 513 due to the elastic force of the limiting spring 515, connecting the docking block 512 and the sliding connecting block 509 so that they cannot be separated, realizing the unfolding of the aseptic operation box, which can increase the volume of the aseptic operation box and better carry out experimental operations.

[0036] The end of the limiting plug 514 facing the mating block 512 is hemispherical, and the diameter of the hemispherical surface is the same as the diameter of the limiting plug 514. The diameter of the limiting plug 514 is the same as the inner diameter of the limiting hole 513. The limiting plug 514 is made of magnetic metal material. The magnetic attraction force of the magnet on the limiting plug 514 is greater than the elastic force of the limiting spring 515. The hemispherical surface at the end of the limiting plug 514 allows the end of the mating block 512 to be pressed against the hemispherical surface at the end of the limiting plug 514 when the mating block 512 is inserted into the mating slot 511, thus allowing the limiting plug 514 to enter the sliding connecting block. The internal compression of the limiting spring 515 within 509 allows the docking block 512 to smoothly enter the docking slot 511 without being obstructed by the limiting plug block 514. The magnet attracts the limiting plug block 514, which can separate the limiting plug block 514 from the limiting hole 513, causing the docking block 512 to lose connection with the sliding connecting block 509. The docking block 512 is separated from the sliding connecting block 509, allowing the two sliding connecting blocks 509 to separate from each other. The sealing end plate 2 can be pushed towards the main body 1 of the operating box, realizing the folding and storage of the aseptic operating box and reducing the space occupied by the aseptic operating box.

[0037] Both sides of the guide rod 506 are equipped with parallel elastic ropes 505. Rotary connecting blocks 507 are fixed to both ends of the elastic ropes 505. Two symmetrically distributed positioning holes 508 are provided on the fixing block 504. Threads with the same direction of rotation and meshing are provided on the outer surface of one end of the rotary connecting block 507 and the inner wall of the positioning hole 508. The end of the rotary connecting block 507 is screwed into the positioning hole 508 through the thread, thus fastening the rotary connecting block 507 and the fixing block 504. Block 504 will not easily separate. After the rotating connecting blocks 507 at both ends of the elastic rope 505 are connected to the two fixed blocks 504 respectively, and when the two sliding connecting blocks 509 lose connection, the elastic rope 505 can elastically contract to pull the two fixed blocks 504, so that the two fixed blocks 504 move closer to each other, and the two horizontal fixed blocks 504 change to be flush with each other and perpendicular to the ground. At this time, the sealing end plate 2 will move closer to the main body 1 of the operating box and compress the telescopic sealing bellows 7, realizing the folding and shrinking of the aseptic operating box.

[0038] Working principle: Pulling the two sealing end plates 2 away from the main body 1 of the operating box causes the telescopic sealing bellows 7 to unfold from the retracted state. When the sealing end plates 2 move, they will drive the two adjacent left and right rotating connecting rods 501 to rotate around the axis of the positioning pin 502. At this time, the two rotating connecting rods 501 will change from a state perpendicular to the ground to a horizontal state. At the same time, the sliding connecting block 509 fixed at the end of the guide connecting rod 506 will slide on the outside of the other guide connecting rod 506 until the two adjacent left and right rotating connecting rods 501 are horizontal. At this time, the two sliding connecting blocks 509 will contact each other, the docking block 512 will be inserted into the docking slot 511, and the limiting plug 514 will be inserted into the limiting hole 513 due to the elastic force of the limiting spring 515. The docking block 512 and the sliding connecting block 509 are connected and cannot be separated, realizing the unfolding of the aseptic operating box, which can increase the volume of the aseptic operating box and better conduct experimental operations.

[0039] When folding the aseptic operating box, simply bring both magnets close to the sliding connecting blocks 509 at the front and rear of the telescopic sealing bellows 7 simultaneously. As the magnets approach the sliding connecting blocks 509, they magnetically attract the limiting plug-in block 514 inside the sliding connecting block 509, causing the limiting plug-in block 514 to enter the sliding connecting block 509 and compress the limiting spring 515. When the limiting plug-in block 514 enters the sliding connecting block 509 and completely disengages from the limiting hole 513, the mating block 512 loses its connection with the sliding connecting block 509, allowing the two sliding connecting blocks 509 to separate. At this time, the two elastic ropes 505 between the upper and lower fixed blocks 504 contract elastically because the two sliding connecting blocks 509 lose connection. The contracting elastic ropes 505 will cause the two fixed blocks 504 to move closer to each other. During the process of moving closer, the two horizontal rotating rods 501 will move closer to each other until the two rotating rods 501 are parallel to each other and perpendicular to the ground. During this process, the sealing end plate 2 will move closer to the end of the operating box body 1 and compress the telescopic sealing bellows 7, so as to realize the shrinking and folding of the aseptic operating box, reduce the space occupied by the aseptic operating box, and facilitate the storage, placement and carrying of the aseptic operating box.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
