Technical Field
[0001] The utility model relates to a secondary biological clean safety cabinet, belonging to the field of biological safety cabinets. Background Art
[0002] A biological clean safety cabinet is a negative pressure filtration exhaust cabinet composed of a cabinet body, a glass door, casters, a fan, a liquid collection tank, a filter, a control panel, an ultraviolet lamp and a lighting lamp, and is widely used in the fields of medical and health, disease prevention and control, food hygiene, environmental monitoring, biological laboratories, etc.
[0003] After the biological clean safety cabinet is used, it needs to be regularly overhauled and maintained by staff. However, the existing glass door usually slides inside the surface of the cabinet body, resulting in very inconvenient disassembly and overhaul, which is very troublesome and greatly reduces the maintenance efficiency of the biological safety cabinet. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is as follows: to provide a secondary biological clean safety cabinet, which solves the problem that after the biological clean safety cabinet is used, it needs to be regularly overhauled and maintained by staff. However, the existing glass door usually slides inside the surface of the cabinet body, resulting in very inconvenient disassembly and overhaul, which is very troublesome and greatly reduces the maintenance efficiency of the biological safety cabinet.
[0005] The technical problem to be solved by the utility model is achieved by the following technical solutions: a secondary biological clean safety cabinet includes a cabinet body and a glass door. The glass door slides on the surface of the cabinet body. Support columns are respectively arranged at both ends of the cabinet body. Sliding grooves for the glass door to slide are opened on both support columns. A clamping member for restricting the sliding of the glass door is fixed at the top of the support column. The clamping member includes a fixed box. Moving blocks are slidably connected to both sides of the fixed box through elastic members. A clamping plate one and a clamping plate two are integrally formed on the two moving blocks respectively. A clamping cavity for clamping the glass door is formed between the clamping plate one and the clamping plate two. A driving structure for driving the two moving blocks to move synchronously is further arranged in the fixed box. A storage structure for placing articles is arranged on the cabinet body. In this embodiment, the elastic member is a spring.
[0006] By adopting the above technical solution, when maintaining and repairing the glass door and disassembling the glass door, first, the staff uses the driving structure to drive the two moving blocks to move in opposite directions respectively. At the same time, the spring is compressed by the pressure of the moving block to generate elastic force. The movement of the moving block drives the separation of the two attracting magnets, so that both the clamping plate I and the clamping plate II are separated from the glass door, so that the glass door is disengaged from the clamping action of the clamping plate I and the clamping plate II. Then, the staff disassembles the baffle, and then slides the glass door downward along the chute until the glass door slides out of the chute, and the glass door can be disassembled for maintenance. The disassembly process is very convenient and simple, greatly improving the maintenance efficiency of the biological safety cabinet.
[0007] Among them, the setting of the clamping plate makes it that when the staff needs to open the glass door and slide the glass door upward for experiments, under the clamping action of the clamping plate I and the clamping plate II, the glass door is not easy to slide down when the staff does not hold the glass door. Among them, rubber strips are bonded to the opposite sides of the two clamping plates. The rubber strips increase the friction between the glass door and the clamping plate, making the glass door less likely to slide within the clamping plate, so that the experiment can be successfully completed.
[0008] The present utility model is further provided that: opposite ends of the two moving blocks are respectively provided with magnets with opposite magnetic polarities.
[0009] By adopting the above technical solution, the setting of the magnets makes the clamping effect of the clamping plate I and the clamping plate II on the glass door more remarkable.
[0010] The present utility model is further provided that: the driving structure includes a driving block slidably connected in the fixed box and located between the two moving blocks. The driving block is provided with a plurality of inclined surfaces. One ends of the two moving blocks are respectively provided with guiding surfaces that cooperate with the inclined surfaces. One end of the driving block away from the moving blocks is provided with a moving rod for sliding the driving block, and the fixed box is provided with a card slot through which the moving rod passes out.
[0011] By adopting the above technical solution, when disassembling the glass door by using the driving structure, first, the staff pushes the moving rod along the card slot towards the direction of the glass door. The movement of the moving rod drives the driving block to move. At the same time, the inclined surface fits with the guiding surface, and under the guiding action of the guiding surface, the two moving blocks move away from the glass door. As the moving blocks move, the two attracting magnets are separated, thereby driving the separation of the clamping plate I and the clamping plate II, enabling the staff to easily disassemble the glass door from the cabinet body.
[0012] The present utility model is further provided that: a fixing plate is fixed above the support column, and an embedding groove for the glass door to slide is opened at the bottom of the fixing plate.
[0013] By adopting the above technical solution, when the glass door is in the closed state, the setting of the fixed plate makes a sealed state formed between the glass door and the cabinet body, preventing the pollution of the outside air to the inside of the biological safety cabinet, and the setting of the slot makes the glass door able to continue to slide upward.
[0014] The utility model is further arranged as follows: The storage structure includes a box cover fixed on the cabinet body. The bottom of the box cover is slidably connected with a storage box through a sliding structure. The sliding structure includes sliders integrally formed on both sides of the storage box, and sliding rails for the sliders to slide are fixed on both sides of the bottom of the box cover.
[0015] By adopting the above technical solution, the storage box is provided for placing disinfection items. When the staff needs to use disinfection items, the staff only needs to pull the handle to make the slider slide in the sliding rail, and then the storage box can be opened to obtain the required disinfection items.
[0016] The beneficial effect of the utility model is that when maintaining and overhauling the glass door and disassembling the glass door, first, the staff uses the driving structure to drive the two moving blocks to move away from the glass door respectively. As the two attracting magnets are separated, the clamping plate I and the clamping plate II are both separated from the glass door, so that the glass door is disengaged from the clamping action of the clamping plate I and the clamping plate II. Then, the staff disassembles the baffle plate, and then slides the glass door downward along the chute until the glass door slides out of the chute, and then the glass door can be disassembled for maintenance. The disassembly process is very convenient and simple, greatly improving the maintenance efficiency of the biological safety cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner
[0024] In order to clearly understand the technical means, creative features, achieved purposes and functions of the present utility model, the present utility model will be further described below with reference to specific drawings.
[0025] As Figure 2 , Figure 3 and Figure 4 shown, a secondary biological clean safety cabinet includes a cabinet body 1 and a glass door 2. The glass door 2 slides on the surface of the cabinet body 1. Support columns 19 are respectively arranged at both ends of the cabinet body 1. Sliding grooves 20 for the glass door 2 to slide are opened on both support columns 19. A clamping member for restricting the sliding of the glass door 2 is fixed at the top of the support column 19. The clamping member includes a fixed box 3. Moving blocks 6 are slidably connected to both sides of the fixed box 3 through elastic members. A first clamping plate 4 and a second clamping plate 5 are integrally formed on the two moving blocks 6 respectively. A clamping cavity 21 for clamping the glass door 2 is formed between the first clamping plate 4 and the second clamping plate 5. A driving structure for driving the two moving blocks 6 to move synchronously is further arranged in the fixed box 3. A storage structure for placing articles is arranged on the cabinet body 1. In this embodiment, the elastic member is a spring 7.
[0026] Wherein, opposite ends of the two moving blocks 6 are respectively provided with magnets 18 with opposite magnetic polarities.
[0027] In addition, a baffle 25 is clamped below the glass door 2. The baffle 25 is detachably connected to the cabinet body 1. Two bolts 27 are arranged on the baffle 25. Clamping holes 26 for the bolts 27 to insert are opened on the cabinet body 1.
[0028] When maintaining and overhauling the glass door 2 and disassembling the glass door 2, first, the staff use the driving structure to drive the two moving blocks 6 to move away from each other. At the same time, the spring 7 is compressed by the pressure of the moving block 6 to generate elastic force. The movement of the moving block 6 drives the separation of the two attracting magnets 18, so that both the clamping plate one 4 and the clamping plate two 5 are separated from the glass door 2, so that the glass door 2 is disengaged from the clamping action of the clamping plate one 4 and the clamping plate two 5. Then, the staff disassemble the baffle 25, and then slide the glass door 2 downward along the chute 20 until the glass door 2 slides out of the chute 20, and the glass door 2 can be disassembled for maintenance. The disassembly process is very convenient and simple, greatly improving the maintenance efficiency of the biosafety cabinet.
[0029] When the glass door 2 needs to be reinstalled on the cabinet body 1 after maintenance and overhaul, first, the staff place the glass door 2 in the chute 20, and at the same time the glass door 2 is between the clamping plate one 4 and the clamping plate two 5. Then slide the glass door 2 upward along the chute 20 until the glass door 2 is completely installed in the chute 20. Subsequently, remove the force of the driving structure on the moving block 6, and at the same time several springs 7 release elastic force in the direction of approaching each other. The elastic force makes the two moving blocks 6 move in the direction of approaching each other, thereby driving the clamping plate one 4 and the clamping plate two 5 to approach, so that the glass door 2 can be firmly installed on the cabinet body 1 by the clamping plate one 4 and the clamping plate two 5, and the installation of the glass door 2 can be completed. The operation process is very convenient, saving time and effort.
[0030] Among them, the setting of the magnet 18 makes the clamping effect of the clamping plate one 4 and the clamping plate two 5 on the glass door 2 more significant.
[0031] In addition, the setting of the clamping plate makes that when the staff need to open the glass door 2 and slide the glass door 2 upward for experiments, under the clamping action of the clamping plate one 4 and the clamping plate two 5, the glass door 2 is not easy to slide down when the staff do not hold the glass door 2. Among them, rubber strips 22 are bonded to the opposite sides of the two clamping plates. The rubber strips 22 increase the friction between the glass door 2 and the clamping plate, making the glass door 2 less likely to slide in the clamping plate one 4 and the clamping plate two 5, so that the experiment can be successfully completed.
[0032] As Figure 3 and Figure 4 shown, the driving structure includes a driving block 8 slidably connected in the fixed box 3 and located between the two moving blocks 6. A number of inclined surfaces 10 are provided on the driving block 8. One ends of the two moving blocks 6 are both provided with guiding surfaces 9 that cooperate with the inclined surfaces 10. One end of the driving block 8 away from the moving block 6 is provided with a moving rod 11 for sliding the driving block 8, and a card slot 12 through which the moving rod 11 passes is opened on the fixed box 3.
[0033] When disassembling the glass door 2 using the driving structure, first, the staff pushes the moving rod 11 along the slot 12 towards the glass door 2. The movement of the moving rod 11 drives the movement of the driving block 8. At the same time, the inclined surface 10 fits with the guiding surface 9, and under the guiding action of the guiding surface 9, the two moving blocks 6 move away from the glass door 2. As the moving blocks 6 move, the two attracting magnets 18 are separated, thereby driving the separation of the clamping plate one 4 and the clamping plate two 5, enabling the staff to easily disassemble the glass door 2 from the cabinet body 1, and the operation process is very simple.
[0034] As Figure 6 shown, a fixing plate 23 is fixed above the support column 19, and a slot 24 for the sliding of the glass door 2 is provided at the bottom of the fixing plate 23.
[0035] When the glass door 2 is in the closed state, the setting of the fixing plate 23 makes the glass door 2 and the cabinet body 1 form a sealed state, preventing the pollution of the outside air to the inside of the biological safety cabinet. The setting of the slot 24 enables the glass door 2 to continue to slide upward.
[0036] As Figure 5 shown, the storage structure includes a box cover 13 fixed to the cabinet body 1. The bottom of the box cover 13 is slidably connected with a storage box 14 through a sliding structure. The sliding structure includes sliders 15 integrally formed on both sides of the storage box 14, and sliding rails 16 for the sliding of the sliders 15 are fixed on both sides of the bottom of the box cover 13.
[0037] Among them, a handle 17 for sliding the storage box 14 is provided on the storage box 14.
[0038] The setting of the storage box is used to place disinfection items. When the staff needs to use disinfection items, the staff only needs to pull the handle 17 to make the slider 15 slide in the sliding rail 16, and then the storage box 14 can be opened to obtain the required disinfection items, which is very convenient.
[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present invention. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
