Description

Technical Field

[0001] The utility model belongs to the technical field of food refrigeration devices, and in particular relates to a food sample refrigeration storage device. Background Art

[0002] The main purpose of refrigerating food samples is to extend the shelf life of food and inhibit the growth and reproduction of microorganisms by lowering the temperature, thereby slowing down the spoilage process of food.

[0003] The Chinese patent with announcement number CN218895559U discloses a refrigerator for storing food samples, including a refrigerator body and a cabinet door rotatably connected to the side of the refrigerator body, the side of the refrigerator body is connected to an assembly plate, and the side of the assembly plate is rotatably connected to a U-shaped movable frame, the two vertical inner walls of the movable frame are connected to two vertical linear motors, and a support plate is connected between the moving parts of the two vertical linear motors; two holes are provided on the top and side of the support plate, two of which are plugged into rods, and the sides of the two rods are connected to the support frame, and the inner cavity of the support frame is provided with multiple conveying rollers, which are rotatably connected to the support frame through a rotating shaft, and the rotating shaft of the middle conveying roller passes through the support frame and extends to the outside of the support frame.

[0004] However, in actual use, when the height is high, the presence of the support frame will hinder the user from pushing the sample or sample tray into the refrigerator, and due to the undulations between the conveyor rollers, the sample bag and the like are at risk of being clamped by the gap between the two conveyor rollers. That is, although the above solution can lift the sample, it will hinder the staff from delivering the sample into the refrigerator. Utility Model Content

[0005] The utility model aims to provide a food sample refrigeration storage device to solve the above-mentioned problem that the existing refrigeration device may hinder staff from putting samples into the refrigeration cabinet.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a food sample refrigeration storage device, comprising

[0007] The refrigerator has a mounting column fixed to the side wall, and a mounting frame is rotatably mounted on the mounting column;

[0008] A lifting assembly is installed in the installation frame;

[0009] A placement plate is installed on the lifting assembly;

[0010] The driving assembly includes a first linear pair and a driving plate. The first linear pair is fixed on the placement plate. The driving plate is installed on the movable end of the first linear pair. The driving plate is in sliding contact with the placement plate.

[0011] The principle and effect of this technical solution:

[0012] 1. By arranging the first linear pair and the driving plate on the placement plate, the user can place the sample or sample box on the placement plate at a lower position, and then lift the placement plate to a specified height through the lifting assembly. The first linear pair can then drive the driving plate to move to abut against and push the sample or sample box placed on the placement plate into the refrigerator. In this way, the sample moves more smoothly and does not require manual pushing, making it more convenient to use. In addition, the first linear pair blocks the side edges, thereby limiting the sample from falling off from the side during the pushing process, thereby ensuring the reliability of the sample entering the refrigerator.

[0013] 2. By setting the mounting columns and mounting frames, the placement plate and drive assembly can be adjusted in position according to the usage of the refrigeration device, thereby meeting the purpose of storage and use without conflict.

[0014] The utility model is further configured as follows: the lifting assembly includes a second linear pair and a lifting plate, the second linear pair is installed on the inner wall of the installation frame, the lifting plate is installed on the movable end of the second linear pair, and the placement plate is installed on the lifting plate.

[0015] The principle and effect of this technical solution: through the setting of the second linear pair and the lifting plate, the height of the placement plate can be adjusted by controlling the lifting of the lifting plate by the second linear pair, so that the placement plate can be in multiple positions to correspond to refrigeration planes of different heights in the refrigerator.

[0016] The utility model is further configured as follows: a mounting groove is provided on the lifting plate, a rotating seat is fixed on the placement plate, the rotating seat is rotatably installed in the mounting groove, and a limiting component is installed at the bottom of the lifting plate, and the limiting component is used to limit the position of the placement plate.

[0017] The principle and effect of this technical solution: through the setting of the installation groove and the rotating seat, the placement plate can be rotated by the coordinated rotation of the rotating seat and the installation groove, that is, the state of the placement plate can be changed without the need to disassemble and assemble the placement plate relative to the lifting plate, which makes it more convenient to use, and the angle of the placement plate is limited by the limiting component, so that the placement plate can maintain a stable working state.

[0018] The utility model is further configured as follows: the limiting assembly includes a vertical rod and a support rod, the vertical rod is fixed to the bottom of the lifting plate, and the two ends of the support rod are detachably connected to the vertical rod and the placement plate respectively.

[0019] The principle and effect of this technical solution: by fixing the vertical rod to the bottom of the lifting plate, the vertical rod and the lifting plate form a whole, and when the length of the support rod and the placement plate is determined, there is only one triangle between the vertical rod, the support rod and the placement plate, that is, under the premise that the vertical rod is stable, the support rod is movable, and the placement plate rotates around one side, the support rod can still form a stable support for the placement plate, so that the placement plate can bear heavy objects without deflection, and the diagonal support rod can withstand greater gravity, and when not in use, the support rod can be disassembled and assembled by disassembly, at this time the triangle restriction is released, and the placement plate can be folded freely.

[0020] The utility model is further configured as follows: connecting plates are rotatably mounted on both ends of the mounting post, a connecting post is fixed on one end of the connecting plate away from the mounting post, and the connecting post is inserted into the mounting frame.

[0021] The principle and effect of this technical solution: through the arrangement of the upper and lower connecting plates and the connecting columns, the installation frame can be rotated 270 degrees around the installation columns by extending the connecting plates, so that the installation frame can face the side of the refrigerator compartment when in use, and can be rotated to the side wall for hidden storage when not in use. The connecting plates and connecting columns also play the role of positioning and supporting the installation frame.

[0022] The utility model is further configured as follows: positioning holes are respectively opened on the adjacent two side walls of the installation column, a through hole is opened on the side wall of the installation frame, a positioning rod is inserted into the through hole, and the end of the positioning rod extends into the positioning hole.

[0023] The principle and effect of this technical solution: the setting of the two positioning holes, the through hole and the positioning rod allows the user to restrict the installation frame to the installation column by plugging and unplugging the positioning rod, and by arranging the through hole and the positioning hole on the side wall, it is convenient for the user to operate the positioning rod, that is, to control the rotation of the installation frame, which is more convenient and quick to use.

[0024] The utility model is further configured as follows: universal wheels are installed at the bottom of the installation frame.

[0025] The principle and effect of this technical solution: The setting of the universal wheel can support the installation frame, thereby reducing the force of the installation frame on the installation column, making the installation frame more stable when rotating around the installation column.

[0040] As attached Figure 1-5 As shown, the present invention discloses a food sample refrigeration storage device, comprising a refrigerator 101, a lifting assembly, a mounting frame 301, a placement plate 501, and a drive assembly. A mounting post 201 is fixed to the side wall of the refrigerator 101 near the door. Connecting plates 202 are rotatably mounted on the upper and lower ends of the mounting post 201. The ends of the connecting plates 202 extend beyond the mounting posts 201, and a connecting post 203 is fixed to the end of the connecting plate 202 away from the mounting posts 201. The connecting post 203 is inserted into the mounting frame 301. The extension of the connecting plates 202 allows the mounting frame 301 to rotate around the mounting posts 201 while also allowing the connecting posts 203 to rotate, thereby allowing the mounting frame 301 to rotate 270 degrees. Universal wheels 304 are mounted on the bottom of the mounting frame 301. The connecting plates 202 can also support the mounting frame 301.

[0041] Positioning holes 204 are defined on the adjacent side walls of mounting post 201. A through-hole 302 is defined on the side wall of mounting frame 301. Positioning rods 303 are inserted into through-holes 302, with the ends of positioning rods 303 extending into positioning holes 204. When connecting plate 202 is rotated 90° and mounting frame 301 is rotated 270°, positioning holes 204 align with through-holes 302. Inserting positioning rods 303 now constrains mounting frame 301 and mounting post 201.

[0042] The lifting assembly includes a second linear pair 401 and a lifting plate 402. The second linear pair 401 is installed on the inner wall of the installation frame 301 (the second linear pair 401 is installed on both the left and right vertical walls). The lifting plate 402 is installed on the movable end of the second linear pair 401. A mounting groove 403 is provided on the lifting plate 402. A rotating seat 502 is fixed on the placement plate 501. The rotating seat 502 is rotatably installed in the mounting groove 403. A limiting assembly is installed at the bottom of the lifting plate 402. The limiting assembly includes a vertical rod 601 and a support rod 602. The vertical rod 601 is fixed to the bottom of the lifting plate 402. The two ends of the support rod 602 are detachably connected to the vertical rod 601 and the placement plate 501 respectively.

[0043] Among them, the connection method between the support rod 602 and the vertical rod 601 and the placement plate 501 can be a method of bolt insertion, nut limiting and use of the connection seat, which is a commonly used detachable connection method and is only briefly described here.

[0044] The driving assembly includes a first linear pair 701 and a driving plate 702. The first linear pair 701 is fixed on the placement plate 501 (one group is arranged in pairs, and the driving plate 702 is installed between the two first linear pairs 701). The driving plate 702 is installed at the movable end of the first linear pair 701, and the driving plate 702 is in sliding contact with the placement plate 501.

[0045] The control ends of the first linear pair 701 and the second linear pair 401 can be a remote controller or a control panel installed on the side wall of the refrigeration chamber, both of which are currently commonly used commercial products and will not be described in detail here.

[0046] The specific implementation process is as follows:

[0047] When in use, first open the cabinet door of the refrigerator 101, then pull the positioning rod 303 to release the restriction of the positioning rod 303 on the mounting frame 301 and the mounting column 201, and then rotate the mounting frame 301 so that the mounting frame 301 is rotated to the corresponding refrigerating chamber of the refrigerator 101. Then, the staff lifts the placement plate 501 and rotates the placement plate 501 around the lifting plate 402 until the placement plate 501 is in a horizontal state, and then connects the two ends of the support rod 602 to the placement plate 501 and the vertical rod 601 respectively. At this time, the position of the placement plate 501 is fixed, and then the food sample or sample box is placed on the placement plate 501 (between the first linear pair 701 and the driving plate 702). Then, the second linear pair 401 is used to drive the placement plate 501 to rise to the specified height, and then the first linear pair 701 can be used to drive the driving plate 702 to move, thereby pushing the sample into the refrigerating chamber of the refrigerator 101.

[0048] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions or features in the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
