Description

Technical Field

[0001] This utility model relates to the field of biological sample refrigeration technology, specifically a biological sampling and culture refrigeration device. Background Technology

[0002] When detecting beneficial or harmful microorganisms in soil, the collected soil samples are processed, and the resulting pure microbial cultures need to be refrigerated to inhibit microbial growth, maintain their activity and characteristics, and facilitate subsequent detection of microbial species, quantity, and function. Therefore, a refrigeration device is required.

[0003] A Chinese patent with authorization announcement number CN220554690U discloses a temporary sample cold storage device, including a cold storage box; a placement plate is movably arranged inside the cold storage box, and placement holes are spaced apart on the placement plate; an adjustable-size first refrigeration space is provided in the inner wall of a second refrigeration component, and a temperature sensor is provided in the first refrigeration space; a clamping mechanism includes a first clamping member disposed on the inner wall of the placement hole; by setting an adjustable-size first refrigeration space, the size of the first refrigeration space can be adjusted according to the amount of sample in the test tube, thereby reducing the space required for refrigeration by the refrigeration unit, facilitating the rapid attainment of the temperature required for sample cold storage, shortening the refrigeration time, and realizing rapid sample cold storage.

[0004] However, the above-mentioned device still has some problems. In practical applications, it is not convenient to limit and clamp sample tubes of different radius sizes. When the refrigerator is moved or shaken slightly, the sample tubes are easy to lose balance and tip over, and the soil samples will spill out, resulting in sample loss and affecting the subsequent detection and analysis of the soil samples. Therefore, a biological sampling and culture refrigeration device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a biological sampling, culture and refrigeration device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A biological sampling and culturing refrigeration device of this utility model includes a refrigeration box. A tray is fitted inside the top of the refrigeration box. Four through slots are equidistantly arranged inside the tray. Four rectangular slots are equidistantly arranged inside the tray, each communicating with one of the through slots. A guide rod is fixedly connected between the two sides of each rectangular slot. Five sliding blocks are slidably installed inside each rectangular slot. Each sliding block has a rod hole inside, and the sliding block is slidably installed on the outside of the guide rod through the rod hole. A compression spring is fixedly connected between every two sliding blocks inside each rectangular slot. The compression springs are all sleeved on the outside of the guide rod. The compression springs have relatively low elasticity. An installation block is installed on one side of each sliding block. Arc-shaped grooves are formed on both sides of the installation block. Rubber pads are fitted on the inner walls of the arc-shaped grooves, enabling the limiting and clamping of sample tubes of the same length but different radii, improving the stability of the sample tubes during refrigeration and preventing tipping.

[0007] Preferably, the top side of the tray located on one side of the through slot is fitted with a cover plate by a hinge and a sealing ring. A fixing buckle is installed on the outer side of the cover plate, and a stabilizing pad made of rubber is fitted on the inner wall of the cover plate. The fixing buckle facilitates the opening and closing of the cover plate. The rubber stabilizing pad enables the top surface of the test tube to be sealed, and the cover plate of a certain through slot can be opened individually to take out and put in the sample test tube, reducing the loss of cold air and ensuring the stability of the refrigeration environment.

[0008] Preferably, the refrigerator has symmetrical grooves on both sides, and five damping rods are fixedly installed between the two sides of each groove. A sliding plate is slidably installed inside the groove at the middle end of each damping rod. A buffer spring is fixedly connected to the top and bottom sides of the sliding plate and the top and bottom sides of the groove, respectively. The buffer springs are respectively sleeved on the outside of the damping rods. The support plate is fixedly installed between the two sliding plates, which can effectively buffer vibration during the refrigerator being subjected to external impact or transportation, and protect the internal sample tubes from damage.

[0009] Preferably, a partition is installed at the bottom of the refrigerator, and several through holes are equally spaced inside the partition. Several thermoelectric cooling plates are equally spaced inside the bottom side of the refrigerator. A movable door is installed on one side of the refrigerator, located on the side of the thermoelectric cooling plate, through a hinge and a sealing ring. The through holes facilitate air circulation, the thermoelectric cooling plates provide a cooling source for the refrigerator, and the movable door facilitates maintenance and repair of the cooling components. This realizes the cooling and refrigeration functions inside the refrigerator, ensuring the preservation temperature of the samples.

[0010] Preferably, the top side of the refrigerator is fitted with a sealing door via a hinge, and a handle is installed at the top edge of the sealing door. The outside of the refrigerator is fitted with a handle via a pin, which facilitates opening and closing the sealing door, thereby facilitating the handling of test tubes. The handle also makes it convenient to lift and move the device.

[0011] Preferably, a control panel is installed on one side of the refrigerator, and the control panel is electrically connected to the electrical components inside the device for operating and controlling the electrical components inside the device, thereby realizing the start and stop control of the thermoelectric cooling plate.

[0012] The advantages of this utility model are:

[0013] 1. When sample test tubes of the same length but different radii are placed in the through groove of the tray, the test tubes will squeeze the mounting block, and the sliding block will slide on the guide rod in the rectangular groove. A compression spring with a small elasticity is installed between the sliding blocks in each rectangular groove. When the sliding block slides under force, the compression spring is compressed. The position of the mounting block is adjusted according to the size of the test tube, so that the rubber pad on the inner wall of the arc groove fits tightly against the test tube, thereby achieving the limiting clamping of test tubes of different sizes.

[0014] 2. When the refrigeration device is subjected to external impact or vibration during transportation, the vibration is transmitted to the tray, and the tray drives the sliding plate to move in the groove. At this time, the buffer spring plays a buffering role and absorbs the vibration energy, while the damping rod restricts the movement of the sliding plate to prevent it from shaking excessively, thereby effectively buffering the vibration and protecting the internal sample tubes from damage.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-4 As shown, a biological sampling and culturing refrigeration device includes a refrigeration box 1. A tray 2 is fitted inside the top of the refrigeration box 1. Four through slots 3 are equidistantly arranged inside the tray 2. Four rectangular slots 4 are equidistantly arranged inside the tray 2, each communicating with one of the through slots 3. A guide rod 5 is fixedly connected between the two sides of each rectangular slot 4. Five sliding blocks 6 are slidably installed inside each rectangular slot 4. Each sliding block 6 has a rod hole inside it, and the sliding block 6 is slidably installed on the outside of the guide rod 5 through the rod hole. A compression spring 7 is fixedly connected between every two sliding blocks 6 inside each rectangular slot 4. The compression springs 7 are all sleeved on the outside of the guide rod 5, and the compression springs 7 have relatively low elasticity. An mounting block 8 is installed on one side of each sliding block 6. Arc-shaped slots 9 are formed on both sides of each mounting block 8, and rubber pads are fitted on the inner walls of the arc-shaped slots 9.

[0024] The top side of the tray 2, located on one side of the through groove 3, is fitted with a cover plate 10 via hinges and sealing rings. A fixing buckle 11 is installed on the outer side of the cover plate 10, and a stabilizing pad 12, made of rubber, is fitted on the inner wall of the cover plate 10. In practical applications, this structure is not convenient for clamping and limiting sample tubes of different radii. When the refrigerator 1 is moved or slightly shaken, the sample tubes easily lose balance and tip over, spilling soil samples and causing sample loss, which affects subsequent processing of the soil samples. According to the test analysis, when sample tubes of the same length but different radii are placed in the through groove 3 of the tray 2, the test tubes will squeeze the mounting block 8. Since the mounting block 8 is connected to the sliding block 6, the sliding block 6 slides on the guide rod 5 in the rectangular groove 4. A compression spring 7 with a small elasticity is installed between the sliding blocks 6 in each rectangular groove 4. When the sliding block 6 is subjected to force and slides, the compression spring 7 is compressed. The position of the mounting block 8 is adjusted according to the size of the test tube so that the rubber pad on the inner wall of the arc groove 9 fits tightly against the test tube, thereby achieving the limiting clamping of test tubes of different sizes.

[0025] After the test tubes are placed, the operator can close the corresponding cover plate 10 by fixing buckle 11 as needed. The rubber stabilizing pad 12 on the inner wall of the cover plate 10 seals the top surface of the test tube, further securing the test tube. When it is necessary to take out or put in a sample test tube in a certain through slot 3, the corresponding cover plate 10 can be opened separately without opening the entire refrigerator 1. Since only a single cover plate 10 is opened, compared with opening the entire refrigerator 1, the loss of cold air can be greatly reduced, ensuring the stability of the cold storage environment inside the refrigerator 1.

[0026] Please see Figure 1 , 2 As shown in Figure 5, the refrigerator box 1 has symmetrical grooves 13 on both sides. Five damping rods 14 are fixedly installed between the two sides of each groove 13. A sliding plate 15 is slidably installed at the middle end of each damping rod 14 inside the groove 13. A buffer spring 16 is fixedly connected to the top and bottom sides of the sliding plate 15 and the top and bottom sides of the groove 13. The buffer spring 16 is respectively sleeved on the outside of the damping rod 14. The support plate 2 is fixedly installed between two sliding plates 15.

[0027] The bottom of the refrigerator box 1 is equipped with a partition 17, and the partition 17 has several through holes 18 equidistantly opened inside. The bottom side of the refrigerator box 1 is equipped with several thermoelectric cooling plates 19 equidistantly. A movable door 20 is installed on one side of the refrigerator box 1, located on the side of the thermoelectric cooling plate 19, through a hinge and a sealing ring.

[0028] The top side of the refrigerator 1 is fitted with a sealing door 21 via a hinge, and a handle 22 is installed at the top edge of the sealing door 21. The outside of the refrigerator 1 is fitted with a handle 23 via a pin, and a control panel 24 is installed on one side of the refrigerator 1. During operation, when detecting beneficial or harmful microorganisms in the soil, the collected soil samples are processed, and the resulting pure microbial cultures need to be refrigerated to inhibit the growth of microorganisms, maintain their activity and characteristics, and facilitate subsequent detection of the types, quantities, and functions of microorganisms. Therefore, a refrigeration device is required. When the refrigeration device is subjected to external impact or vibration during transportation, the vibration is transmitted to the tray 2, and the tray 2 drives the sliding plate 15 to move within the groove 13. At this time, the buffer spring 16 plays a buffering role, absorbing the vibration energy, and the damping rod 14 restricts the movement of the sliding plate 15 to prevent it from shaking excessively, thereby effectively buffering the vibration and protecting the internal sample tubes from damage.

[0029] When refrigerating soil sample tubes, the thermoelectric cooling plate 19 is powered on via the control panel 24, and cooling is achieved using the Peltier effect. The generated cold air circulates inside the refrigerator 1 through the through-hole 18, thereby regulating the temperature inside the refrigerator 1 to meet the temperature requirements for sample preservation. The movable door 20 on one side of the refrigerator 1 is opened when maintenance and repair of the thermoelectric cooling plate 19 and other refrigeration components are required, ensuring the normal operation of the refrigeration system, maintaining a stable low-temperature environment inside the refrigerator 1, and ensuring that the sample tubes are preserved at a suitable temperature. The specific model of the thermoelectric cooling plate 19 is LHP-1800CPV.

[0030] When it is necessary to refrigerate soil sample tubes, the operator first lifts the refrigeration device using handle 23 and moves it to a suitable position. Then, the operator holds handle 22 to open the sealing door 21 and places the sample tube into the through slot 3 of tray 2. After placement, the operator closes cover 10 and sealing door 21 in sequence. When it is necessary to remove the sample tube, the operator opens sealing door 21 again using handle 22, finds the corresponding through slot 3 according to the sample number, opens the corresponding cover 10 using the fixing buckle 11, removes the sample tube, and then closes cover 10 and sealing door 21 to complete a complete process of sample refrigeration and retrieval.

[0031] Working principle: When it is necessary to refrigerate soil sample tubes, first lift the refrigeration device by the handle 23 and move it to the appropriate position. Then, hold the handle 22 to open the sealing door 21 and put the sample tubes into the through groove 3 of the tray 2. When sample tubes of the same length and different radius sizes are placed in the through groove 3 of the tray 2, the tubes will squeeze the mounting block 8. Since the mounting block 8 is connected to the sliding block 6, the sliding block 6 slides on the guide rod 5 in the rectangular groove 4. A compression spring 7 with a small elasticity is installed between the sliding blocks 6 in each rectangular groove 4. When the sliding block 6 is subjected to force and slides, the compression spring 7 is compressed. Adjust the position of the mounting block 8 according to the size of the tube so that the rubber pad on the inner wall of the arc groove 9 fits tightly against the tube, thereby achieving the limiting clamping of tubes of different sizes. After placement, close the cover plate 10 and the sealing door 21 in sequence.

[0032] Operators can close the corresponding cover plate 10 by fixing buckle 11 as needed. The rubber stabilizing pad 12 on the inner wall of the cover plate 10 seals the top surface of the test tube and further fixes the test tube. When it is necessary to take out or put in a sample test tube in a certain through slot 3, the corresponding cover plate 10 can be opened separately without opening the entire refrigerator 1. Since only a single cover plate 10 is opened, compared with opening the entire refrigerator 1, the loss of cold air can be greatly reduced, ensuring the stability of the cold storage environment inside the refrigerator 1.

[0033] When the refrigeration unit is subjected to external impact or vibration during transportation, the vibration is transmitted to the tray 2. The tray 2 drives the sliding plate 15 to move in the groove 13. At this time, the buffer spring 16 plays a buffering role and absorbs the vibration energy, while the damping rod 14 restricts the movement of the sliding plate 15 to prevent it from shaking excessively, thereby effectively buffering the vibration and protecting the internal sample tubes from damage.

[0034] When refrigerating soil sample tubes, the thermoelectric cooling plate 19 is powered on by the control panel 24, and the Peltier effect is used to achieve cooling. The generated cold air circulates inside the refrigerator 1 through the through hole 18, thereby regulating the temperature inside the refrigerator 1 to meet the temperature requirements for sample preservation. The movable door 20 on one side of the refrigerator 1 is opened when it is necessary to maintain and repair the thermoelectric cooling plate 19 and other cooling components to ensure the normal operation of the refrigeration system, maintain a stable low temperature environment inside the refrigerator 1, and ensure that the sample tubes are preserved at a suitable temperature.

[0035] When it is necessary to remove the sample tube, the operator opens the sealing door 21 again through the handle 22, finds the corresponding through slot 3 according to the sample, opens the corresponding cover plate 10 through the fixing buckle 11, takes out the sample tube, and then closes the cover plate 10 and the sealing door 21 to complete a complete process of sample refrigeration and retrieval.
