Description

Technical Field

[0001] The invention belongs to the technical field of temperature control boxes, and in particular relates to a temperature control observation box based on ice crystal microscopy. Background Art

[0002] The temperature control box uses temperature control technology and is generally used in scientific research to conduct temperature-controlled freezing microscopic observations. The temperature-controlled freezing microscopic observation system is a high-end scientific research equipment that can fix, fracture, and coat samples under low-temperature conditions and observe microscopic morphology under low-temperature conditions. The temperature-controlled freezing system used for ice crystal microscopic observation is a device specially designed to observe the microstructure of ice crystals under low-temperature conditions.

[0003] However, there are some problems with the existing technology: at present, when the temperature-controlled observation box is cooled down for ice crystal microscopy, cold air needs to be generated and discharged into the inside of the observation box. Due to the high density of cold air, it is easy to accumulate at the bottom of the observation box. Although the observation box has the function of air circulation to help the cold air to be active in the box, some of the cold air will still be trapped at the bottom of the observation box. This results in the inability to further accelerate the cooling and crystallization when the sample is placed on the freezing table, which cannot meet the current situation. Therefore, we propose a temperature-controlled observation box based on ice crystal microscopy. Summary of the invention

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Positioning assembly 4, there are multiple groups of positioning assembly 4, and the positioning assembly 4 and the extraction assembly 1 are arranged in pairs, the positioning assembly 4 is fixedly connected to the injection component 102, and the positioning assembly 4 is transmission-connected to the observation platform 2041, so that the extraction assembly 1 is fixedly arranged with the observation platform 2041 through the positioning assembly 4; like Figures 1 to 14 As shown, by designing that the positioning component 4 is fixedly connected to the injection component 102, the positioning component 4 can drive the injection component 102 to slide around the observation platform 2041 and fix it at different points to achieve the best crystallization pre-cooling treatment for different samples.

[0039] The lifting assembly 3 is provided with multiple groups, and the lifting assembly 3 is provided in pairs with the extraction assembly 1, the extraction head 101 is slidably connected with the injection component 102, the lifting assembly 3 is provided on the outside of the observation platform 2041, and the lifting assembly 3 is fixedly connected with the positioning assembly 4, and the end of the lifting assembly 3 is fixedly connected with the extraction head 101, so that the lower end of the extraction head 101 is close to or away from the injection component 102 through the lifting assembly 3.

[0040] like Figures 1 to 14 As shown, by the design of fixed connection between the end of the lifting component 3 and the extraction head 101, the height position of the extraction head 101 can be changed. Therefore, when different types of samples have different crystallization temperature points and the amount of cold air accumulated below the observation box 201 is different, at this time, the height position of the extraction head 101 can be adjusted to optimally extract the amount of cold air to the sample, thereby effectively and reasonably using the cold air.

[0041] Further, the extraction head 101 is composed of a conical tube 1011 and a plurality of groups of arc plates 1013, the conical tube 1011 is slidably connected to the injection component 102, and the outer side of the conical tube 1011 is fixedly connected to the lifting assembly 3, the plurality of groups of arc plates 1013 are arranged in a ring shape and are equidistant, and the plurality of groups of arc plates 1013 are rotatably installed around the lower end of the conical tube 1011, an adjustment mechanism is provided at the lower end of the conical tube 1011, and the plurality of groups of arc plates 1013 are movably connected to the adjustment mechanism, so that the plurality of groups of arc plates 1013 are moved closer to or farther from each other through the adjustment mechanism; like Figures 1 to 14 As shown, through the design of the conical tube 1011, the conical tube 1011 can cover a large area of ​​cold air by utilizing its own conical characteristics, thereby improving the efficiency of extracting cold air.

[0042] Specifically, Figure 12 to Figure 14 As shown, the adjustment mechanism includes a fixed column 1014 and a bearing column 1016, the fixed column 1014 is fixedly installed inside the conical tube 1011, and the bearing column 1016 is fixedly installed at the lower end of the fixed column 1014, a plurality of adjustment grooves are provided on the outer side of the bearing column 1016, and the adjustment grooves are arranged corresponding to the arc plate 1013, a driving groove is provided inside the bearing column 1016, the plurality of adjustment grooves are communicated with the inside of the driving groove, and the driving groove is rotatably connected with the driving bevel gear 16, the bearing column 1016 The lower end is rotatably connected with a conical head 1015, and the conical head 1015 is fixedly connected to the driving bevel gear 16, and one end of the inner part of multiple sets of adjustment grooves is rotatably connected with a driven bevel gear 17, and multiple sets of driven bevel gears 17 are meshingly connected with the driving bevel gear 16, and one end of multiple sets of driven bevel gears 17 is fixedly installed with an adjusting screw 18, and the outer side of the adjusting screw 18 is threadedly connected with a threaded sleeve 22, and one end of the threaded sleeve 22 is rotatably connected with a connecting seat 23, and the connecting seat 23 is slidably installed on the inner side of the arc plate 1013.

[0043] In summary, through the design of the adjustment mechanism, the angles of multiple groups of arc plates 1013 can be changed, and multiple groups of arc plates 1013 cooperate with each other to change the area of ​​the exhaust end of the conical tube 1011, so that the optimal exhaust area of ​​the conical tube 1011 can be adjusted according to the different requirements of the cold air extraction amount, thereby further improving the practicality of the conical tube 1011.

[0044] Furthermore, the injection component 102 includes a positioning shell 1021, a connecting tube 1022 and a sliding shell 1023. The conical tube 1011 is slidably sleeved on the outside of the connecting tube 1022. The sliding shell 1023 is fixedly installed on one side of the positioning shell 1021. A protective frame 5 is fixedly installed around the upper surface of the observation platform 2041. A plurality of sliding cavities are provided on the outside of the protective frame 5. The sliding cavities are arranged in pairs with the sliding shell 1023. The sliding shell 1023 is slidably installed inside the sliding cavity. It should be noted that a first sealing sleeve 1012 is commonly sleeved on the outer side of multiple groups of arc plates 1013, and a second sealing sleeve 1017 is commonly sleeved on the inner side of multiple groups of arc plates 1013, and the first sealing sleeve 1012 is fixedly sleeved on the outer side of the connecting pipe 1022, and the second sealing sleeve 1017 is fixedly installed around the inner wall of the connecting pipe 1022.

[0045] In summary, by designing the first sealing sleeve 1012 and the second sealing sleeve 1017, it can be ensured that after the angle of the arc plate 1013 is changed, the gap between the two adjacent groups of arc plates 1013 will not excessively affect the circulation of cold air.

[0046] like Figures 1 to 14 As shown, the sliding shell 1023 is slidably installed inside the sliding cavity. This design can effectively avoid collisions between multiple sets of sliding shells 1023.

[0047] Further, a avoidance groove is provided on one side of the sliding shell 1023, a first screw lifting mechanism 1025 is provided inside the avoidance groove, and the inside of the avoidance groove is connected to the injection head 1024 by the first screw lifting mechanism 1025, and a placement groove is provided on one side of the positioning shell 1021, one end of the connecting tube 1022 passes through the other side of the positioning shell 1021 to the inside of the placement groove, and a plurality of sections of telescopic tubes 1026 are provided between one end of the connecting tube 1022 and one end of the injection head 1024; like Figures 1 to 7 As shown, a multi-section telescopic tube 1026 is arranged between one end of the connecting tube 1022 and one end of the injection head 1024. When the injection head 1024 moves up and down, the multi-section telescopic tube 1026 can ensure the transmission of cold air. Compared with traditional hose transmission, the multi-section telescopic tube 1026 can avoid pipe bending and affect the transmission efficiency of cold air. Therefore, the use of the multi-section telescopic tube 1026 can more directly ensure the efficiency of cold air transmission.

[0048] It should be noted that the first screw lifting mechanism 1025 mentioned above adopts a screw lifting structure, and the structure using a screw for transmission lifting has become an existing mature technology. Those skilled in the art should know how to install and use the first screw lifting mechanism 1025. Therefore, the present invention will not be elaborated here.

[0049] Specifically, Figure 5 As shown, the two ends of the outer side of the injection head 1024 are fixedly installed with the first segment sleeves 7, and the ends of the two groups of first segment sleeves 7 that are away from each other are respectively fixedly installed at the two ends inside the avoidance groove, thereby sealing the avoidance groove and further preventing the generated cold air from entering the inside of the avoidance groove.

[0050] Furthermore, avoidance holes are provided at both ends of the lower outer side of the connecting tube 1022, and an exhaust fan 1028 is slidably connected to the lower end of the inner part of the connecting tube 1022, and a power button 1027 is provided at one end of the exhaust fan 1028, and one end of the power button 1027 passes through one set of the avoidance holes to the outer side of the connecting tube 1022, and a fastening bolt 15 is provided at the other end of the exhaust fan 1028, so that the exhaust fan 1028 and the connecting tube 1022 are fixed to each other by the fastening bolt 15, and the second segment sleeve 14 is provided at both ends of the outer side of the power button 1027 and the fastening bolt 15, and the second segment sleeve 14 is fixedly installed inside the avoidance hole; like Figures 11 to 14 As shown, by providing a power button 1027 at one end of the exhaust fan 1028, when the conical tube 1011 slides downward and squeezes the power button 1027, the exhaust fan 1028 can work. When the conical tube 1011 rises, the internal conical characteristics can avoid squeezing the power button 1027, so that the conical tube 1011 can be lowered to the optimal position, triggering the exhaust fan 1028 to work automatically, thereby realizing rapid extraction of cold air.

[0051] Secondly, through the design of the fastening bolts 15, the height position of the exhaust fan 1028 inside the connecting pipe 1022 can be changed, so that it can be adjusted accordingly according to the amount of cold air accumulated below the observation box 201 to achieve the optimal exhaust position.

[0052] It should be noted that, through the design of the second-section sleeve 14, when the exhaust fan 1028 is adjusted in height, the second-section sleeve 14 can effectively seal the avoidance hole, thereby ensuring the normal transmission and use of cold air.

[0053] Specifically, Figures 1 to 6 As shown, both ends of one side of the sliding shell 1023 are provided with receiving grooves, and the insides of the two groups of receiving grooves are rotatably connected with auxiliary cleaning components 6.

[0054] The auxiliary cleaning component 6 includes a cleaning scraper 601, the lower end of the cleaning scraper 601 is rotatably installed at the lower end of the storage groove, and a rotating rod 602 is fixedly installed at the lower end of the cleaning scraper 601, the rotating rod 602 passes through the outside of the sliding shell 1023 to the inside of the storage groove, and the rotating rod 602 is fixed to the sliding shell 1023 by bolts, and multiple groups of grooves are provided at both ends of one side of the cleaning scraper 601, and the multiple groups of grooves are arranged at equal intervals, and an ice-breaking head 603 is rotatably connected inside the groove, and the ice-breaking head 603 is arranged in a triangular shape, and the multiple groups of ice-breaking heads 603 on the same side are commonly fixedly connected with a rotating rod 604, and one end of the rotating rod 604 is located at the upper end of the cleaning scraper 601, and the rotating rod 604 is fixed to the cleaning scraper 601 by bolts.

[0055] Through the design of the cleaning scraper 601 and the ice-breaking head 603, when the sample ice crystals are microscopically finished, the cleaning scraper 601 can be rotated to a horizontal angle, and then the rotating rod 604 can be rotated to make the ice-breaking head 603 flip one hundred and eighty degrees, and then the sliding shell 1023 can be controlled to move through the adjustment component 4, so that the ice formed on the upper surface of the observation plate 2042 can be broken and cleaned, so as to assist the staff in cleaning the observation plate 2042, thereby further improving the practicality of the temperature-controlled observation box 201.

[0056] Further, the positioning assembly 4 includes a sleeve shell 401 and a positioning gear 403. The sleeve shell 401 is fixedly sleeved on the outside of the connecting tube 1022. A rotating groove is provided on one side of the sleeve shell 401. The positioning gear 403 is rotatably installed inside the rotating groove. A plurality of sets of tooth grooves are provided around the upper end of the outer side of the observation platform 2041, and the adjusting gear is meshed and connected with the tooth grooves, so that the positioning gear 403 is transmission-connected with the observation platform 2041 through the tooth grooves; a servo motor 404 is provided at the upper end of the rotating groove, and one end of the output shaft of the servo motor 404 is fixedly connected with the positioning gear 403. A start button 402 is provided at one end of the bottom of the sleeve shell 401, and the start button 402 is electrically connected with the servo motor 404, so that the start button 402 is used to control the switch of the servo motor 404; like Figures 1 to 10 As shown, through the design of the positioning gear 403 meshing with the tooth groove, the positioning gear 403 rotates, which can pass through the tooth groove to make the set shell 401 slide one circle on the outside of the observation platform 2041, thereby realizing the position change of the injection head 1024, so that the position of the injection head 1024 can be adjusted according to different samples, further improving the practicality of the observation box 201 for ice crystal microscopy.
