Description
Technical Field
[0001] This utility model belongs to the technical field of food testing sample preservation devices, and particularly relates to a food testing sample preservation device. Background Technology
[0002] Food testing refers to the process of systematically analyzing and testing food samples to ensure food safety and quality, and compliance with relevant regulations and standards. Food sample preservation devices are used to store and protect samples during food testing. In summary, the existing technology has the following problems: Food sample preservation cabinets, as a type of food testing sample preservation device, serve a refrigeration function to ensure samples maintain their original state during testing. However, the cabinet frames are typically fixed with bolts, which restricts sample placement and makes it difficult to properly store samples of different sizes and shapes. This can lead to situations where samples are too large to fit or too small, wasting space and hindering space utilization. Furthermore, existing food sample preservation cabinets lack components for convenient adjustment of the cabinet frame spacing. Therefore, this paper proposes a food testing sample preservation device to solve these problems. Utility Model Content
[0003] To address the problems existing in the prior art, this utility model provides a food testing sample preservation device. It features a food sample preservation cabinet with the advantage of easily adjustable shelf spacing, solving the problem that existing food sample preservation cabinets, while serving a refrigeration function to ensure samples maintain their original state during testing, typically use bolts to fix the cabinet shelves. This fixed shelf design restricts sample placement, making it difficult to properly preserve samples of different sizes and shapes. This can lead to situations where oversized samples cannot be placed or undersized samples waste space, hindering space utilization. Furthermore, existing food sample preservation cabinets lack components for easily adjustable shelf spacing.
[0004] This utility model is implemented as follows: a food testing sample preservation device includes a food sample preservation cabinet and several cabinet frames. The cabinet frames are movably connected to the inner cavity of the food sample preservation cabinet. Two movable frame frames are fixedly connected to the left and right sides of the inner cavity of the food sample preservation cabinet. An adjustable frame shell is movably connected to the inner cavity of the movable frame frame. Several support plates are provided in the inner cavity of the food sample preservation cabinet. An adjustment device is provided in the inner cavity of the adjustable frame shell.
[0005] As a preferred embodiment of this utility model, the adjusting device includes two adjusting fixing blocks. The two adjusting fixing blocks have opposite sides that penetrate through the adjusting frame shell and extend to the outer side of the inner cavity of the adjusting frame shell. The adjusting fixing blocks have adjusting holes on their surfaces, and springs are fixedly connected to the inner cavities of the adjusting holes. By setting the adjusting device, when the spacing of the cabinet rack needs to be adjusted according to the height of the food to be stored, the adjusting device has the function of adjusting the height of the cabinet rack.
[0006] As a preferred embodiment of this utility model, the inner cavity of the adjustment frame housing is fixedly connected to two adjustment plates that cooperate with the adjustment hole. The surface of the adjustment plate is movably connected to the inner cavity of the adjustment hole, and the surface of the spring is fixedly connected to the surface of the adjustment plate. By setting the adjustment plate, when the adjustment block moves, it will drive the adjustment hole to move along the surface of the adjustment plate. The cooperation between the adjustment hole and the adjustment plate has a limiting effect on the movement position of the adjustment block.
[0007] In a preferred embodiment of this invention, each of the two adjusting plates is fixedly connected to an extrusion plate on one side opposite to the other. The inner cavity of the adjusting frame housing is movably connected to two figure-eight extrusion frames that cooperate with the extrusion plates. The inner cavity of the figure-eight extrusion frames is movably connected to the surface of the extrusion plates. The side of the figure-eight extrusion frames away from the adjusting fixing block penetrates the adjusting frame housing and extends to the outer side of the inner cavity of the adjusting frame housing. By setting the extrusion plates and the figure-eight extrusion frames, when the figure-eight extrusion frames move, they can generate extrusion force on the extrusion plates. The two extrusion plates subjected to the extrusion force can drive the adjusting fixing block to move.
[0008] As a preferred embodiment of this utility model, the inner cavity of the adjustment frame shell is fixedly connected to a positioning plate that works in conjunction with the figure-eight extrusion frame. The surface of the positioning plate is movably connected to the inner cavity of the figure-eight extrusion frame. By setting the positioning plate, the figure-eight extrusion frame is pulled, causing it to move along the surface of the positioning plate. The positioning plate restricts the movement of the figure-eight extrusion frame.
[0009] As a preferred embodiment of this utility model, the front and rear sides of the inner cavity of the movable frame are provided with adjustment and fixing grooves that cooperate with the adjustment and fixing blocks. The surface of the adjustment and fixing block contacts the inner cavity of the adjustment and fixing groove. There are several adjustment and fixing grooves, which are evenly distributed on the front and rear sides of the inner cavity of the movable frame. By setting the adjustment and fixing grooves, when the frame is moved to the appropriate position, the figure-eight squeezing frame is released, and the restoring force generated by the spring returning to its shape will drive the adjustment and fixing block to be inserted into the inner cavity of the adjustment and fixing groove. The cooperation between the adjustment and fixing block and the adjustment and fixing groove has a limiting effect on the position of the frame.
[0010] In a preferred embodiment of this invention, the front and rear sides of the adjustment rack housing are fixedly connected to limiting displacement blocks, and the left and right sides of the inner cavity of the food sample storage cabinet are fixedly connected to two limiting displacement frames that cooperate with the limiting displacement blocks. The surface of the limiting displacement block is movably connected to the inner cavity of the limiting displacement frame, the surface of the support plate is fixedly connected to the surface of the limiting displacement block, and the top of the support plate contacts the bottom of the cabinet. By setting the limiting displacement blocks and limiting displacement frames, when the adjustment rack housing moves, it will drive the limiting displacement blocks to move along the inner cavity of the limiting displacement frames. The cooperation of the limiting displacement blocks and limiting displacement frames has a limiting effect on the movement position of the adjustment rack housing.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model solves the problem of existing food sample storage cabinets, which are a type of food testing sample storage device, have a refrigeration function to ensure that the samples maintain their original state during the testing process. The cabinet frame of the food sample storage cabinet is usually fixed with bolts. The fixed cabinet frame makes it impossible to place samples flexibly. Samples of different sizes and shapes cannot be stored properly. It is easy to have the phenomenon that the sample is too large to be placed or the sample is too small to be placed, which wastes space and makes it difficult to make full use of space. However, the existing food sample storage cabinets used for food testing sample storage do not have a component for convenient adjustment of the spacing of the cabinet frame.
[0013] 2. This utility model, by setting an adjustment device, will drive two adjusting blocks to move closer to each other when the pressing column plate moves. When the adjusting blocks move, the adjusting hole will move along the surface of the adjusting plate. At the same time, the force generated when the adjusting blocks move will cause the spring to undergo elastic deformation. The restoring force generated by the spring returning to its shape will drive the adjusting blocks to be inserted into the inner cavity of the adjusting groove. The adjustment device has the function of adjusting the height of the cabinet. Attached Figure Description

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0021] like Figures 1 to 4 As shown in the figure, the present invention provides a food testing sample preservation device, including a food sample preservation cabinet 1 and several cabinet frames 2. The cabinet frames 2 are movably connected to the inner cavity of the food sample preservation cabinet 1. Two movable frame frames 3 are fixedly connected to the left and right sides of the inner cavity of the food sample preservation cabinet 1. An adjustable frame shell 4 is movably connected to the inner cavity of the movable frame frame 3. Several support plates 5 are provided in the inner cavity of the food sample preservation cabinet 1. An adjusting device 6 is provided in the inner cavity of the adjustable frame shell 4.
[0022] refer to Figure 4 The adjusting device 6 includes two adjusting fixing blocks 601. The two adjusting fixing blocks 601 have opposite sides that penetrate through the adjusting frame shell 4 and extend to the outside of the inner cavity of the adjusting frame shell 4. The surface of the adjusting fixing block 601 is provided with an adjusting hole 602, and a spring 603 is fixedly connected to the inner cavity of the adjusting hole 602.
[0023] The above solution is adopted: by setting the adjustment device 6, when the spacing of the cabinet 2 needs to be adjusted according to the height of the food to be stored, the adjustment device 6 has the function of adjusting the height of the cabinet 2.
[0024] refer to Figure 4 The inner cavity of the adjustment frame housing 4 is fixedly connected to two adjustment plates 7 that cooperate with the adjustment hole 602. The surface of the adjustment plate 7 is movably connected to the inner cavity of the adjustment hole 602, and the surface of the spring 603 is fixedly connected to the surface of the adjustment plate 7.
[0025] The above solution is adopted: by setting the adjustment plate 7, when the adjustment fixing block 601 moves, it will drive the adjustment hole 602 to move along the surface of the adjustment plate 7. The cooperation between the adjustment hole 602 and the adjustment plate 7 has a limiting effect on the movement position of the adjustment fixing block 601.
[0026] refer to Figure 4Each of the two adjusting plates 7 has a pressing plate 8 fixedly connected to one side of the opposite side. The inner cavity of the adjusting frame 4 is movably connected to two figure-eight pressing frames 9 that cooperate with the pressing plate 8. The inner cavity of the figure-eight pressing frame 9 is movably connected to the surface of the pressing plate 8. The side of the figure-eight pressing frame 9 away from the adjusting fixing block 601 passes through the adjusting frame 4 and extends to the outside of the inner cavity of the adjusting frame 4.
[0027] The above scheme is adopted: by setting the extrusion column plate 8 and the figure-eight extrusion frame 9, when the figure-eight extrusion frame 9 moves, it can generate extrusion force on the extrusion column plate 8. The two extrusion column plates 8 subjected to extrusion force can drive the adjustment fixing block 601 to move.
[0028] refer to Figure 4 The inner cavity of the adjustment frame 4 is fixedly connected to a positioning plate 10 that works with the figure-eight extrusion frame 9, and the surface of the positioning plate 10 is movably connected to the inner cavity of the figure-eight extrusion frame 9.
[0029] The above solution is adopted: by setting a positioning plate 10; pulling the figure-eight extrusion frame 9, the figure-eight extrusion frame 9 moves along the surface of the positioning plate 10. The positioning plate 10 restricts the movement position of the figure-eight extrusion frame 9.
[0030] refer to Figure 3 The front and rear sides of the inner cavity of the movable frame 3 are provided with adjustment fixing grooves 11 that cooperate with the adjustment fixing block 601. The surface of the adjustment fixing block 601 contacts the inner cavity of the adjustment fixing groove 11. There are several adjustment fixing grooves 11, which are evenly distributed on the front and rear sides of the inner cavity of the movable frame 3.
[0031] The above solution is adopted: by setting the adjustment fixing groove 11, when the adjustment frame shell 4 moves to the appropriate position, the figure-eight squeezing frame 9 is released, and the restoring force generated by the spring 603 returning to its shape will drive the adjustment fixing block 601 to be inserted into the inner cavity of the adjustment fixing groove 11. The cooperation between the adjustment fixing block 601 and the adjustment fixing groove 11 has a limiting effect on the position of the adjustment frame shell 4.
[0032] refer to Figure 2 Limited displacement blocks 13 are fixedly connected to the front and rear sides of the adjustment frame shell 4. Two limited displacement frames 12 that cooperate with the limited displacement blocks 13 are fixedly connected to the left and right sides of the inner cavity of the food sample storage cabinet 1. The surface of the limited displacement block 13 is movably connected to the inner cavity of the limited displacement frame 12. The surface of the support plate 5 is fixedly connected to the surface of the limited displacement block 13. The top of the support plate 5 is in contact with the bottom of the cabinet frame 2.
[0033] The above scheme is adopted: by setting the displacement limiting block 13 and the displacement limiting frame 12, when the adjustment frame shell 4 moves, it will drive the displacement limiting block 13 to move along the inner cavity of the displacement limiting frame 12. The cooperation of the displacement limiting block 13 and the displacement limiting frame 12 has a limiting effect on the movement position of the adjustment frame shell 4.
[0034] The working principle of this utility model:
[0035] When using the food sample storage cabinet 1 for food testing samples, if the spacing of the cabinet rack 2 needs to be easily adjusted, the user first pulls the two figure-eight squeezing frames 9 to opposite sides. As the figure-eight squeezing frames 9 move, they exert squeezing force on the squeezing plates 8. The two squeezing plates 8, subjected to this force, will move closer together. This movement of the squeezing plates 8 will also cause the two adjusting blocks 601 to move closer together. The movement of the adjusting blocks 601 will cause the adjusting holes 602 to move along the surface of the adjusting plate 7. Simultaneously, the force generated by the movement of the adjusting blocks 601 causes the spring 603 to elastically deform. When the adjusting blocks 601 disengage from the adjusting groove 11... When the adjustment frame 4 is fully moved into the inner cavity of the adjustment frame 4, pull the adjustment frame 4 to the top or bottom. When the adjustment frame 4 moves, it will drive the displacement limiting block 13 to move along the inner cavity of the displacement limiting frame 12. At the same time, when the displacement limiting block 13 moves, it will drive the support plate 5 to move. When the support plate 5 moves to the appropriate height, release the two figure-eight squeezing frames 9. The restoring force generated by the spring 603 returning to its shape will drive the adjusting fixing block 601 to be inserted into the inner cavity of the adjusting fixing groove 11. The cooperation of the adjusting fixing block 601 and the adjusting fixing groove 11 has a limiting effect on the position of the adjustment frame 4 and the support plate 5. Then, place the cabinet 2 on the support plate 5. At this time, the distance between the food sample storage cabinet 1 used for food testing sample storage and the cabinet 2 is conveniently adjusted.
[0036] In summary, this food testing sample preservation device, through the coordinated use of the adjustment device 6, adjustment fixing block 601, adjustment hole 602, spring 603, and adjustment fixing groove 11, solves the problem that existing food sample preservation cabinets, which are a type of food testing sample preservation device, have a refrigeration function to ensure that the samples maintain their original state during the testing process. These cabinets typically use bolts to fix the cabinet frame, which prevents flexible sample placement and makes it difficult to properly preserve samples of different sizes and shapes. This can lead to situations where samples are too large to fit or too small, resulting in wasted space and difficulty in fully utilizing space. Furthermore, existing food testing sample preservation cabinets lack components for convenient adjustment of the cabinet frame spacing.
