Description

Technical Field

[0001] The utility model relates to the field of cold storages, and particularly relates to a modular fresh-keeping cold storage. Background Art

[0002] A cold storage is a kind of refrigeration equipment. A cold storage refers to an equipment that creates an environment with a temperature or humidity different from that outdoors by artificial means, and is also a constant temperature and humidity storage equipment for items such as food, liquids, chemicals, medicines, vaccines, and scientific experiments. Cold storages are usually located near transportation ports or the place of origin.

[0003] A fresh-keeping cold storage is a low-temperature warehouse used for storing and preserving various foods (such as fruits, vegetables, meats, etc.). It delays food spoilage and extends its fresh-keeping period by controlling the temperature and humidity inside the warehouse.

[0004] In the prior art, a Chinese utility model patent with the publication number "CN218821199U" and the patent name "A modular spliced cold storage" discloses a cold storage. The patent records a technical solution that "the cold storage main body is formed by sequentially connecting multiple splicing modules, which is convenient for flexibly controlling the length of the cold storage, and the flexibility and application range are greatly improved; since the splicing modules are connected to each other by bolts and nuts, it is convenient for operation, and it is also convenient to add / remove splicing modules, further improving the flexibility".

[0005] However, in the actual use process of this technical solution, due to no sealing measures being taken for the cold storage after modular splicing, the sealing performance of the modular cold storage during use is poor, and cold air leakage is likely to occur, affecting the fresh-keeping effect. At the same time, when the modular cold storage is assembled together by bolts and nuts, the operation is relatively cumbersome, which brings inconvenience to the combined splicing operation of the modular fresh-keeping cold storage, and further affects the assembly efficiency of the modular fresh-keeping.

[0006] Therefore, to solve the above technical problems, the utility model proposes a modular fresh-keeping cold storage. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figure 1 - Figure 4As shown in the figure, a modular fresh-keeping cold storage includes a left storage body 1, a right storage body 2 and an intermediate storage body 4. On the outer side walls of the left storage body 1 and the right storage body 2, there are respectively fixedly connected with storage doors 3. Between the left storage body 1 and the right storage body 2, a number of intermediate storage bodies 4 are fixedly connected through a connecting mechanism 5. And the connecting mechanism 5 includes a connecting frame 9, a concave seat 12, a screw rod 15, a concave plate 18 and a connecting rod 21. On the front and rear walls of the connecting frame 9, there are respectively fixedly connected with a set of upper and lower symmetric concave seats 12. And the screw rod 15 is movably connected in the concave opening of the concave seat 12 through the rotating rods 16 at both ends. The concave plate 18 is movably connected with the screw rod 15 through the screw holes 19 on the top surface. And the concave plate 18 is also movably connected with the concave seat 12 through the sliding strips 20 on both sides of the inner wall of the concave opening. The connecting rod 21 is fixedly connected to both sides of the top surface of the concave plate 18.

[0024] As Figure 2 shown, on the opposite side walls of the left storage body 1 and the right storage body 2 and on the left and right side walls of the intermediate storage body 4, there are respectively fixedly installed pressing frames 6. The pressing frames 6 provided on the left storage body 1, the right storage body 2 and the intermediate storage body 4 are used to cooperate with the rubber sealing frame strips 11 in the sealing grooves 10 on both sides of the connecting frame 9;

[0025] As Figure 2 shown, on the front and rear walls of the left storage body 1 and the right storage body 2 and on the left and right sides of the front and rear walls of the intermediate storage body 4, there are respectively fixedly installed a set of upper and lower symmetric fixing blocks 7. And on the top surface of the fixing blocks 7, there are provided fixing holes 8. Through the fixing holes 8 provided on the fixing blocks 7 installed on the left storage body 1, the right storage body 2 and the intermediate storage body 4, after the connecting rod 21 is inserted into the fixing holes 8, the left storage body 1 and the intermediate storage body 4, the right storage body 2 and the intermediate storage body 4, and between the intermediate storage bodies 4 can be quickly connected and fixed together;

[0026] As Figure 3 shown, on the left and right side walls of the connecting frame 9, there are respectively provided sealing grooves 10 corresponding to the pressing frames 6. And in the grooves of the sealing grooves 10, there are fixedly installed rubber sealing frame strips 11. When the pressing frames 6 are embedded into the sealing grooves 10 and extrude the rubber sealing frame strips 11 in the sealing grooves 10, it can ensure the sealing performance of the assembled modular fresh-keeping cold storage during use, and avoid the leakage of cold air at the connection parts and reduce the fresh-keeping effect on the materials;

[0027] As Figure 3 and Figure 4 shown, on the front and rear walls of the connecting frame 9, there are respectively fixedly installed a set of upper and lower symmetric concave seats 12. And on the top surface and the bottom surface of the front concave opening of the concave seat 12, there are respectively provided rotating holes 13. On the left and right side walls of the concave seat 12, there are also respectively provided sliding grooves 14. Through the rotating holes 13 provided on the concave seat 12, the rotating rods 16 can realize the rotation operation in the rotating holes 13. And the provided sliding grooves 14 can enable the sliding strips 20 to slide in the sliding strips 20;

[0028] As Figure 3 and Figure 4 shown, rotating rods 16 are fixedly installed at the upper and lower ends of the screw rod 15 respectively, and the rotating rods 16 are movably installed in the rotating holes 13. A knob 17 is fixedly installed at the bottom end of the lower rotating rod 16. A threaded hole 19 is formed in the top surface of the concave plate 18, and the concave plate 18 is threadedly connected to the screw rod 15 through the threaded hole 19. Slide bars 20 are also fixedly installed on the left and right sides of the inner wall of the rear notch of the concave plate 18 respectively, and the slide bars 20 are movably installed in the sliding grooves 14. A set of left and right symmetric connecting rods 21 are also fixedly installed on the top surface of the concave plate 18, and the connecting rods 21 are inserted and installed in the fixing holes 8. By rotating the knob 17, the screw rod 15 is driven to rotate through the rotating rod 16, so that the concave plate 18 moves along the screw rod 15 through the threaded hole 19, and the slide bars 20 slide in the sliding grooves 14. Until the connecting rods 21 are inserted into the fixing holes 8, the left storage body 1 and the middle storage body 4, the middle storage body 4 and the middle storage body 4, and the middle storage body 4 and the right storage body 2 can be quickly connected and fixed together, and by increasing or decreasing the middle storage body 4, a fresh-keeping cold storage with different length dimensions can be assembled and combined in a modular manner.

[0029] It should be noted that the present utility model is a modular fresh-keeping cold storage. The connecting frame 9 is placed between the left storage body 1 and the middle storage body 4, between the middle storage body 4 and the middle storage body 4, and between the middle storage body 4 and the right storage body 2. After the pressing frames 6 installed on the opposite side walls of the left storage body 1 and the left and right side walls of the middle storage body 4 are respectively inserted into the sealing grooves 10 opened on the left and right side walls of the connecting frame 9, the knobs 17 on the opposite side walls of the concave seats 12 installed above and below the front and rear side walls of the connecting frame 9 are rotated in sequence. The knob 17 will drive the rotating rods 16 installed at the upper and lower ends of the screw rod 15 to rotate in the rotating holes 13 opened on the top surface and the bottom surface of the front concave opening of the concave seat 12, and the rotating rod 16 will drive the screw rod 15 to rotate, so that the concave plate 18 moves in the opposite direction along the screw rod 15 through the screw holes 19 opened on the top surface. When moving, the sliding strips 20 installed on the left and right sides of the inner wall of the rear concave opening of the concave plate 18 will slide in the sliding grooves 14 opened on the left and right side walls of the concave seat 12 until the connecting rods 21 installed on the left and right sides of the top surface of the concave plate 18 are inserted into the fixing holes 8 installed on the top surface of the fixing block 7. After the knob 17 can no longer be rotated, several middle storage bodies 4 can be connected and fixed between the left storage body 1 and the right storage body 2 and combined into an integral fresh-keeping cold storage. When the fresh-keeping cold storage is in use, since the pressing frame 6 is located in the sealing groove 10 and cooperates with the rubber sealing strip 11 installed in the sealing groove 10, the airtightness of the fresh-keeping cold storage during use can be ensured, and the problem of cold air leakage at the connection parts between the left storage body 1, the right storage body 2 and the middle storage body 4 can be avoided. Thus, by adding or deleting the middle storage body 4 between the left storage body 1 and the right storage body 2, a fresh-keeping cold storage with different length dimensions can be modularly combined to achieve the purpose of meeting the actual use requirements, which not only achieves the purpose of facilitating the assembly of the modular cold storage, but also improves the assembly efficiency of the modular fresh-keeping cold storage.

[0030] In summary, the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components therein can be replaced with equivalents, or some of the technical features can be equivalently replaced. All should be included within the protection scope of the present utility model within the spirit and principle of the present utility model.
