Description

Technical Field

[0001] The utility model relates to the technical field of sample display cabinets, in particular to a sample display cabinet for cryopreservation bags and EVA film materials. Background Art

[0002] With the continuous development of scientific research and medical technology, many biological samples and medical supplies need to be stored and displayed in a low-temperature environment to ensure their activity and effectiveness. For example, samples such as cryopreservation bags and EVA film materials are widely used in the fields of scientific research, medicine, and bioengineering. In order to display the characteristics and usage effects of these samples, display cabinets have become an important device. However, traditional display cabinets are mostly used in normal temperature environments, and for the display of samples that need to be stored at low temperatures, existing display cabinets often fail to meet their special requirements.

[0003] Currently, the display cabinets on the market usually can only provide one display environment and cannot take into account the two needs of normal temperature and low temperature. At the same time, during low-temperature display, frost is likely to accumulate on the inner wall of the display cabinet, which will affect the display effect and appearance of the samples after long-term use. In addition, due to the lack of an intelligent control system in traditional display cabinets, operators cannot detect the storage temperature in a timely manner and need to manually defrost frequently, increasing the workload and the risk of errors. Therefore, there is an urgent need for an improved display cabinet design that can effectively display samples in normal temperature and low-temperature environments and has the characteristics of automation and intelligence, improving the display effect and operation convenience.

[0030] In order to more clearly explain the overall concept of the present utility model, the following will be described in detail by way of examples in combination with the accompanying drawings of the specification.

[0031] Embodiment 1

[0032] As Figures 1-6As shown in the figure, the utility model provides a technical solution: a cryopreservation bag and an EVA film sample display cabinet, including: a display cabinet body 1, one side of the inner wall of the display cabinet body 1 is fixedly connected with a partition 8, a conventional display part inner cavity 9 is arranged on one side of the partition 8, and a low-temperature resistant display part inner cavity 10 is arranged on the other side of the partition 8. A temperature sensor 11 is fixedly connected to one side of the inner wall of the display cabinet body 1, and the temperature sensor 11 is arranged on one side of the inner wall of the low-temperature resistant display part inner cavity 10. A fixing plate 12 is fixedly connected to the bottom end of the inner wall of the display cabinet body 1, and a mounting plate 13 is fixedly connected to one side of the inner wall of the display cabinet body 1. The fixing plate 12 is correspondingly connected to the mounting plate 13. A hydraulic rod 14 is fixedly connected to one side of the inner wall of the display cabinet body 1. The bottom end of the hydraulic rod 14 is fixedly connected to the outer wall of the upper end of the fixing plate 12, and the side wall of the hydraulic rod 14 is fixedly connected to one side of the mounting plate 13. The upper end of the hydraulic rod 14 is fixedly connected with a defrosting mechanism 15. Second chutes 16 are provided on both the display cabinet body 1 and one side of the partition 8. Brackets 17 are arranged in both the conventional display part inner cavity 9 and the low-temperature resistant display part inner cavity 10, and the brackets 17 are used to place samples. For the setting position of the brackets 17, specifically in the conventional display part inner cavity 9, a bracket 17 is fixedly connected to the upper end of the mounting plate 13, or a bracket 17 can also be installed on the side wall of the conventional display part inner cavity 9; specifically in the low-temperature resistant display part inner cavity 10, brackets 17 can be installed on both the bottom plate or the side wall of the low-temperature resistant display part inner cavity 10. The brackets 17 are made of polytetrafluoroethylene and are transparent in color;

[0033] The defrosting mechanism 15 includes a sliding plate 151 slidably connected to one side of the inner wall of the display cabinet body 1. A defrosting layer 152 is arranged on the outer wall of the sliding plate 151. Sliders 153 are fixedly connected to both outer walls of the sliding plate 151. The second chutes 16 provided on both the display cabinet body 1 and one side of the partition 8 are correspondingly connected and are slidably connected to the sliders 153 provided on one side of the sliding plate 151.

[0034] In this embodiment, a display cabinet body 1 is designed. In the middle of one side of the inner wall of the display cabinet body 1, a partition 8 is fixedly connected, which can divide the inner wall of the display cabinet body 1 into two partitions: a normal display part inner cavity 9 and a low-temperature resistant display part inner cavity 10. The normal display part inner cavity 9 is set at room temperature, while the low-temperature resistant display part inner cavity 10 is set at low temperature. A liquid nitrogen adding device can be used to add liquid-phase nitrogen into the low-temperature resistant display part inner cavity 10 to maintain its internal temperature at a required level. Therefore, samples with different requirements can be displayed. A temperature sensor 11 is installed inside the inner wall of the display cabinet body 1, and the temperature sensor 11 is correspondingly connected to the low-temperature resistant display part inner cavity 10, which can play a monitoring role to prevent the cold air of the liquid-phase nitrogen filled in the low-temperature resistant display part inner cavity 10 from diffusing and resulting in a temperature that does not meet the usage requirements. On one side of the inner wall of the display cabinet body 1 and at the bottom end of the low-temperature resistant display part inner cavity 10, a fixing plate 12 is fixedly connected. An installation plate 13 is correspondingly connected to the upper end of the fixing plate 12, and the installation plate 13 is fixedly connected to one side of the inner wall of the display cabinet body 1. Since the low-temperature resistant display part inner cavity 10 is filled with liquid-phase nitrogen for preservation, after a long time, the liquid-phase nitrogen will diffuse cold air outward, causing frost to form on the inner wall of the display cabinet body 1, which will affect the display effect. For this reason, a sliding plate 151 is provided on one side of the inner wall of the low-temperature resistant display part inner cavity 10. A hydraulic rod 14 is fixedly connected to the lower end of the sliding plate 151. The hydraulic rod 14 is fixed by the fixing plate 12 and the installation plate 13. Sliders 153 are fixedly connected to both sides of the sliding plate 151, and the sliders 153 are slidably connected to a second chute 16 opened on the inner wall of the low-temperature resistant display part inner cavity 10. Therefore, when the hydraulic rod 14 is started, the hydraulic rod 14 will drive the sliding plate 151 to slide on one side of the inner wall of the low-temperature resistant display part inner cavity 10 through the sliders 153. At this time, a defrosting layer 152 provided on the outer wall of the sliding plate 151 will act on the inner wall of the display cabinet body 1, thereby clearing the frost formed on the inner wall of the display cabinet body 1 and avoiding affecting its display effect. The sliders 153 are slidably connected to the second chute 16, which enables the sliding plate 151 to slide stably during defrosting and prevents it from shifting. A support 17 is connected to the upper end of the installation plate 13. The support 17 can support the sample and then conduct the display. Since the support 17 is in a liquid-phase nitrogen environment, it is made of polytetrafluoroethylene material, which can maintain its toughness at the temperature of liquid nitrogen, will not become brittle, and has excellent chemical stability and will not react with liquid nitrogen.

[0035] Embodiment 2

[0036] As Figures 1-3As shown in the figure, a temperature control display 2 is fixedly connected to the outer wall on one side of the display cabinet body 1. A first sealing layer 3 is provided on the inner wall on one side of the upper end of the display cabinet body 1. A first sliding groove 4 is opened on one side of the first sealing layer 3. A pull-out plate 5 is slidably connected to one side of the inner wall of the first sliding groove 4. Both the display cabinet body 1 and the pull-out plate 5 are made of transparent and orange materials. The lower end of the pull-out plate 5 is correspondingly connected to the inner cavities 9 and 10 of the conventional display part and the low-temperature resistant display part provided on the inner wall of the display cabinet body 1. A pulling block 6 is fixedly connected to the upper end of the pull-out plate 5. A second sealing layer 7 is fixedly connected to the outer wall on one side of the pull-out plate 5. Both the first sealing layer 3 and the second sealing layer 7 are made of rubber materials. The second sealing layer 7 provided on the outer wall on one side of the pull-out plate 5 is correspondingly connected to the first sealing layer 3 provided on the inner wall on one side of the upper end of the display cabinet body 1.

[0037] In this embodiment, by designing a temperature control display 2 fixedly connected to the outer wall on one side of the display cabinet body 1, the temperature control display 2 can play a role in regulating the temperature. And a first sealing layer 3 is provided on the inner wall on one side of the upper end of the display cabinet body 1. A first sliding groove 4 is opened on one side of the first sealing layer 3. A pull-out plate 5 is slidably connected to the inner wall of the first sliding groove 4. And the pull-out plate 5 is correspondingly connected to the inner cavities 9 and 10 of the conventional display part and the low-temperature resistant display part opened in the display cabinet body 1. Therefore, it can play a role in covering. And a second sealing layer 7 is provided on one side of the pull-out plate 5. The second sealing layer 7 can be correspondingly connected to the first sealing layer 3. Both the first sealing layer 3 and the second sealing layer 7 are made of rubber materials (such as fluororubber), which can still maintain a certain elasticity in a low-temperature environment. Therefore, it has a certain sealing performance, avoiding the leakage of the cold air of the liquid-phase liquid nitrogen filled in the inner cavity 10 of the low-temperature resistant display part, resulting in the inability to maintain a stable temperature inside it, and then causing damage to its samples. And a pulling block 6 is fixedly connected to the outer wall on the upper end of the pull-out plate 5. The pulling block 6 can be toggled to drive the pull-out plate 5 to slide to one side on the inner wall of the first sliding groove 4, and then perform the operation of shielding and sealing. In this device, both the display cabinet body 1 and the pull-out plate 5 are made of orange transparent materials, and the samples inside the display cabinet body 1 can be directly observed from the outside.

[0038] Working principle:

[0039] Such as Figures 1-6As shown, the samples to be displayed are placed in the conventional display part cavity 9 and the low-temperature display part cavity 10 opened in the display cabinet body 1 according to the needs, and the samples are placed on the bracket 17. The liquid nitrogen adding device is used to add liquid nitrogen into the low-temperature display part cavity 10 to maintain the interior at a temperature that meets the requirements. When the product is placed in the low-temperature display part cavity 10 filled with liquid nitrogen, the temperature in the low-temperature display part cavity 10 can be controlled according to the temperature sensor 11 and the temperature control display 2 provided on the outer wall of the display cabinet body 1 to avoid the diffusion of the liquid nitrogen cold air in the low-temperature display part cavity 10, resulting in its temperature not meeting the use requirements. After long-term use, frost will form inside the low-temperature display part cavity 10, that is, the inner wall of the display cabinet body 1, which will affect the display effect. In response to this, the hydraulic rod 14 can be started, and the hydraulic rod 14 will drive the sliding plate 151 to slide on one side of the inner wall of the low-temperature resistant display cavity 10 through the slider 153. At this time, the defrosting layer 152 provided on the outer wall of the sliding plate 151 will act on the inner wall of the display cabinet body 1, thereby clearing the frost formed on the inner wall of the display cabinet body 1, thereby avoiding affecting its display effect. After the display sample is placed, the pull block 6 can be moved to slide the pull plate 5 to one side along the inner wall of the first slide groove 4. At this time, the second sealing layer 7 and the first sealing layer 3 will be connected correspondingly. Since the first sealing layer 3 and the second sealing layer 7 are both made of rubber material, they have a certain sealing performance, thereby avoiding the leakage of liquid nitrogen cold air filled in the low-temperature resistant display cavity 10, resulting in the inability to maintain a stable internal temperature, and then causing damage to the sample.

[0040] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
