Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laboratory storage cabinets, in particular to a storage cabinet dedicated to a biosafety laboratory. Background Art
[0002] Biosafety laboratories, also known as biological laboratories, are biological laboratories and animal laboratories that can avoid or control the hazards of harmful biological factors being operated through protective barriers and management measures to meet biosafety requirements. As the requirements for quality control become more and more stringent, the demand for constant temperature and humidity environments is increasing, and the application areas are becoming wider and wider.
[0003] The existing biosafety laboratory dedicated storage cabinets can be set according to the temperature of the environment required by the culture dish when in use. However, due to the different culture conditions required by the organisms in different culture dishes, the culture dishes under different culture conditions cannot be uniformly placed in the cabinet for uniform culture. Therefore, the use of the cabinet has certain limitations. During the culture, multiple storage refrigerators are needed, or the subsequent culture of different organisms can be carried out after a culture cycle is completed, which greatly increases the experimental cycle. At the same time, if the sealing film of the culture dish is damaged during use, it is easy to affect the internal environment of the entire locker, which is not conducive to subsequent use and experiments.

Both ends of the bottoms of the basic cabinet 1 and the movable cabinet 2 are fixedly connected with connecting plates 5. The connecting plates 5 are inserted into the corresponding accommodating grooves 4 and fit with the inner walls thereof. The connecting plates 5 and the accommodating grooves 4 are threadedly connected with locking bolts 6. The locking bolts 6 penetrate the corresponding cabinet body to facilitate fixing the connecting plates 5 in the accommodating grooves 4.
[0027] A box door 7 is provided on one side of the outside of the basic cabinet 1 and the movable cabinet 2, and a number of partitions 8 are provided inside the basic cabinet 1 and the movable cabinet 2. Installation strips are fixedly connected on both sides of the inner walls of the basic cabinet 1 and the movable cabinet 2, and sliding grooves 11 corresponding to the installation strips are provided at both ends of the partition 8 to facilitate the disassembly and installation of the partition 8.
[0028] An incubator 10 is provided between two adjacent partitions 8, and corresponding limiting grooves 9 are opened on the top and bottom of several partitions 8. The limiting grooves 9 have an isosceles trapezoidal cross-section and a wide-mouth design, which facilitates the rapid insertion of the incubator 10 into the limiting grooves 9, reduces the limitations and difficulty of insertion, and facilitates better use. The incubator 10 is located in the limiting grooves 9 between two adjacent partitions 8.
[0029] An embedded handle 12 is provided on the outside of the incubator 10, a top cover 13 is provided on the top of the incubator 10, a slot 14 corresponding to the top cover 13 is opened on the top of the incubator 10, and a sealing ring is fixedly connected to the edges around the bottom of the top cover 13. After the biological culture dish is placed in the incubator 10, the top cover 13 is covered on the incubator 10 to facilitate its closure.
[0030] Two gas interfaces 15 are provided on one side of the incubator 10 away from the embedded handle 12 , and gas supply interfaces 16 corresponding to the two gas interfaces 15 are provided on one side of the basic cabinet 1 and the movable cabinet 2 away from the cabinet door 7 .
[0031] The gas interface 15 includes a fixed cylinder 151 which is fixedly connected to the incubator 10, a limiting ring 152 is fixedly connected to the inner wall of the fixed cylinder 151, a nozzle 153 is slidably connected to the inner wall of the limiting ring 152, a plurality of air holes 154 are provided around the nozzle 153, a fixing ring 155 is fixedly connected to the end of the nozzle 153, a spring 156 is fixedly connected between the fixing ring 155 and the limiting ring 152, a sealing ring 157 is fixedly connected to the inner wall of the nozzle 153, a bracket 158 is fixedly connected to the inner wall of the sealing ring 157, and a ejector pin 159 is fixedly connected at the center of the bracket 158.
[0032] The air supply interface 16 includes an air pipe 161, an annular groove 162 is formed on the inner wall of the air pipe 161, and a sphere 163 is disposed inside the annular groove 162. The end of the air pipe 161 is inserted into the nozzle 153, and the end of the air pipe 161 is correspondingly matched with the sealing ring 157 and the end of the fixing tube 151. Each incubator 10 has two air pipes 161, and the two air pipes 161 are connected to the external fresh air system, which is convenient for supplying and exhausting cold air in the incubator 10, and ensuring that the incubator 10 has a temperature environment that meets the requirements of the culture dish experiment.
[0033] When in use, the culture dish is placed in the incubator 10 , and after the top cover 13 is covered on the incubator 10 , it is placed in the limiting groove 9 between the two partitions 8 .
[0034] Each incubator 10 corresponds to two air supply interfaces 16. In the initial state, one of the air supply interfaces 16 in the basic cabinet 1 and the movable cabinet 2 is connected to an external air conditioner to facilitate the supply of cold air. Under the pressure of the cold air flow, the ball 163 is located at one end of the annular groove 162 to block the air pipe 161, thereby blocking the cold air. When there is no incubator 10 connected, it is convenient to close the air pipe 161. The other air supply interface 16 is connected to the external filtered fresh air system for exhaust. Therefore, when the two air supply interfaces 16 are connected to the incubator 10, a complete air flow loop can be formed (Note: the air supply interface 16 used for exhaust does not contain the ball 163).
[0035] As the incubator 10 is gradually inserted into the limiting groove 9, the gas interface 15 at the end of the incubator 10 gradually docks with the gas supply interface 16, the air pipe 161 is inserted into the fixed cylinder 151, the end of the air pipe 161 abuts against the fixed ring 155, compresses the spring 156, and at the same time gradually pushes the nozzle 153 out of the fixed cylinder 151, so that the air hole 154 is connected to the internal environment of the incubator 10. In the initial state, the ejector pin 159 abuts against the ball 163, so that the ball 163 is separated from the notch of the annular groove 162. At this time, the external cold air can enter the nozzle 153 along the air pipe 161, and then spray out from the air hole 154, enter the incubator 10, and be discharged through another air supply interface 16 after circulation, so as to provide a suitable environment for the culture dish.
[0036] Regarding the temperature control in the incubator 10 in this device, it can be monitored by existing technical means such as a temperature sensing module, and the cold air intake of the air pipe 161 can be adjusted accordingly. Since the specific temperature control here is not the main innovation of this device, it will not be elaborated here.
[0037] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
