DETAILED DESCRIPTION

[0027] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-9 The utility model provides a technical solution: a telescopic platform is arranged inside the refrigerator body 1, including:

[0029] A sealing door 21 is provided on one side of the refrigerator body 1;

[0030] A supporting device is provided inside the refrigerator body 1;

[0031] The double-layer conveying mechanism is arranged at the upper end of the supporting device and is used to convey the sample box 3.

[0032] It should be noted that when working, the sealed door 21 is opened, the sample box 3 is placed on the double-layer conveying mechanism, and then the power equipment is turned on to drive the double-layer conveying mechanism to move on the supporting device, driving the sample box 3 to move inside the refrigerator body 1. Through the design of the double-layer conveying mechanism, the automatic conveyance of the sample box 3 is realized. The design of the double-layer structure also makes full use of the internal space of the refrigerator and improves space utilization. The design of the sealed door 21 effectively reduces the number and time of opening the refrigerator door, thereby reducing the impact of the external environment on the internal temperature of the refrigerator, maintaining the stability of the sample storage environment, and ensuring the safety and effectiveness of the sample.

[0033] In one embodiment, the double-layer conveying mechanism includes a first transmission frame 25 provided on a supporting device and a second transmission frame 26 provided on an upper end of the first transmission frame 25 . The first transmission frame 25 is connected to the second transmission frame 26 via a power member 27 .

[0034] This design, see Figure 2-8 The double-layer design makes more efficient use of the internal space of the refrigerator body 1. The layered layout of the first transmission rack 25 and the second transmission rack 26 can significantly increase the transmission distance of the sample box 3 without increasing the external size of the refrigerator. The first transmission rack 25 serves as the bottom transmission platform, firmly supporting the entire double-layer conveying mechanism and ensuring the stability of the sample box 3 during the transmission process. The second transmission rack 26 is connected to the first transmission rack 25 through the power piece 27, realizing the fast and accurate transmission of the sample box 3 between the two layers.

[0035] In one embodiment, the supporting device includes a base frame 22 fixed inside the refrigerator body 1, a slide rail 221 fixed to the upper end of the base frame 22, a side frame 23 fixed to the upper end of the base frame 22 for supporting the power part 27, and a bracket 24 arranged at the upper end of the base frame 22 for supporting the first transmission frame 25, and the bracket 24 is slidably set on the slide rail 221.

[0036] This design, see Figure 3-8 The bottom frame 22 serves as the cornerstone of the entire supporting device and is firmly fixed inside the refrigerator body 1, providing a solid supporting foundation for the upper structure and ensuring the stability and reliability of the double-layer conveying mechanism during operation. There are two slide rails 221, so that the bracket 24 can slide freely and stably thereon, which provides a smooth trajectory for the movement of the first transmission rack 25, which not only improves the transmission efficiency, but also makes the transmission process smoother and reduces the noise and wear caused by friction and vibration. The side frame 23 is used to be connected to the power part 27 to ensure the stability and efficiency of power transmission. The bracket 24 serves as the direct supporting component of the first transmission rack 25. Its sliding setting on the slide rail 221 makes the supporting structure adjustable, and the position of the first transmission rack 25 can be adjusted according to actual needs.

[0037] In one embodiment, the first transfer rack 25 includes a first conveying plate 251 fixed to the upper end of the bracket 24, a guide rail 252 fixed to the upper end of the first conveying plate 251, and a slider 253 slidably arranged on the guide rail 252. The lower end of the first conveying plate 251 is provided with a fixing groove 25102 for fixing the bracket 24.

[0038] This design, see Figure 5-8 The first conveyor plate 251 is fixed to the upper end of the bracket 24, and the power member 27 drives the first conveyor plate 251 to slide on the slide rail 221, ensuring the stable support of the entire conveyor rack in the refrigerator body 1. This design effectively prevents shaking and displacement during the transmission process, providing a solid guarantee for the safe transmission of samples. The introduction of the guide rail 252 provides a precise sliding track for the slider 253, so that the second conveyor rack 26 can move smoothly along the guide rail 252, thereby improving the accuracy and efficiency of the transmission.

[0039] In one embodiment, the second transfer rack 26 includes a second conveying plate 261 fixed to the upper end of the slider 253 and a connecting rack 262 fixed to the upper end of the second conveying plate 261 and connected to the sealing door 21. The second conveying plate 261 is provided with an installation groove 26101 at the position of the slider 253, and the upper end of the second conveying plate 261 is provided with a placement groove 26102 for placing the sample box 3.

[0040] This design, see Figure 5-8 The second conveyor plate 261 is firmly fixed to the upper end of the slider 253 through the mounting groove 26101, ensuring the stability and accuracy of the second conveyor rack 26 during the sliding process. The guide rail 252 is provided with two groups, which can effectively prevent the second conveyor plate 261 from shaking and deflecting during the transmission process, thereby ensuring the safety of the sample. The connecting frame 262 tightly connects the second conveyor plate 261 with the sealing door 21, so that when the sealing door 21 is opened or closed, the second conveyor rack 26 can move accordingly, thereby realizing the quick removal and placement of the sample box 3. This design improves the convenience of operation and reduces the possibility of the sample being exposed to the external environment. The design of the placement groove 26102 provides a clear placement position for the sample box 3, so that the samples can be arranged in an orderly and neat manner on the second conveyor plate 261.

[0041] In one embodiment, the power member 27 includes a motor 271 fixed to the upper end of the first conveying plate 251, a rotating shaft 2711 fixed to the power output end of the motor 271 and passing through the first conveying plate 251, a first gear 272 sleeved on the rotating shaft 2711, a second gear 273 provided at the lower end of the first conveying plate 251 away from the first gear 272, and a gear belt 274 sleeved on the first gear 272 and the second gear 273. The gear belt 274 is fixedly connected to the side frame 23. The side of the gear belt 274 close to the second conveying plate 261 is connected to the second conveying plate 261 via a fixing frame 254. The fixing frame 254 is fixedly connected to the gear belt 274 via a fixing block 2541. A limiting groove 25101 for movement of the fixing frame 254 is provided at a position of the first conveying plate 251 corresponding to the fixing frame 254.

[0042] This design, see Figure 4-8 The motor 271 serves as a power source, and the rotating shaft 2711 transmits the power of the motor 271 to the first gear 272, and then to the second gear 273 through the gear belt 274. The gear belt 274 is fixedly connected to the side frame 23. When the motor 271 drives the gear belt 274 to rotate clockwise, the first conveying plate 251 moves to the side close to the bottom frame 22. Since the other side of the gear belt 274 is fixedly connected to the second conveying plate 261 through the fixing frame 254, the second conveying plate 261 can also be driven to move to the side close to the bottom frame 22. When the motor 271 drives the gear belt 274 to rotate counterclockwise, the first conveying plate 251 moves to the side close to the bottom frame 22. 1 moves toward the side away from the bottom frame 22, and drives the second conveying plate 261 to move toward the side away from the bottom frame 22, thereby pushing the sealed door 21 out of the refrigerator body 1, so that the sample box 3 on the second conveying plate 261 can be taken. This gear transmission mechanism not only has high transmission efficiency, but also can maintain the stability and continuity of power, ensuring the smooth operation of the double-layer conveying mechanism. By controlling the speed and direction of the motor 271, the moving speed and direction of the gear belt 274 can be precisely controlled, thereby achieving precise displacement control of the second conveying plate 261 and the sample box 3. This design improves the accuracy and efficiency of sample transmission.

[0043] In a specific embodiment, a moving block 275 is provided at the upper end of the first conveying plate 251, and the second gear 273 is sleeved on the moving block 275. A mounting block 277 is provided at the upper end of the first conveying plate 251, and an adjusting bolt 276 is threadedly connected to the mounting block 277. The adjusting bolt 276 is rotatably connected to the moving block 275 on the side close to the moving block 275.

[0044] This design, see Figure 7 ,as well as Figure 8, turn the adjusting bolt 276 to adjust the distance between the moving block 275 and the mounting block 277, and then adjust the distance between the second gear 273 and the first gear 272, and tighten the gear belt 274.
