Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to an intermediate column structure of a freezer. Background Technique

[0002] A freezer is an electrical appliance specifically used for freezing and storing food or other items that require a low-temperature environment; the main difference between it and a refrigerator is that a freezer is mainly used for freezing rather than refrigerating, and usually does not have a refrigerating chamber. The volume of a freezer is usually larger than that of a refrigerator, it can hold more things, and has a stronger load-bearing capacity.

[0003] The Chinese utility model patent with the publication number CN209085147U was published on July 9, 2019, and discloses a replaceable column freezer, which relates to the field of refrigeration equipment, including a cabinet body and a control panel arranged at the top of the cabinet body. A cabinet door is arranged at the front end of the cabinet body, a column is arranged between the cabinet doors, and the cabinet door is connected to the column or the cabinet body through a hinge. The cabinet body includes an integrally formed inner wall insulation layer. An irregular protrusion is arranged at the front end of the inner wall insulation layer near the cabinet door. A slot with the same shape as the irregular protrusion is arranged on the column, and the irregular protrusion and the matching slot can be in interference fit. It realizes the effect of improving the overall service life of the freezer by structurally improving the traditional integrally formed insulation cabinet body and making the cabinet body columns replaceable.

[0004] However, the above-mentioned disclosed solution has the following deficiencies: the columns in the prior art are made of a combination of multiple materials, which easily causes gaps. It is also necessary to use a foaming process to fill the cavity inside the column to improve the insulation effect, and the overall manufacturing process is complex and costly. Content of the Utility Model

[0005] The purpose of the utility model is to solve the technical problem that the columns in the prior art are made of a combination of multiple materials, which easily causes gaps, and it is also necessary to use a foaming process to fill the cavity inside the column to improve the insulation effect, and the overall manufacturing process is complex and costly, and to provide an intermediate column structure of a freezer.

[0006] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions;

[0007] An intermediate column structure of a freezer described in the utility model includes a vertical beam; an installation cavity is opened in the vertical beam; limiting clamping plates are symmetrically fixedly connected in the installation cavity; a heat-insulating material is inserted into the installation cavity; a heating wire is inserted into the limiting clamping plate; and a sheet metal panel is inserted into the limiting clamping plate.

[0008] Further, strengthening bars are symmetrically fixedly connected in the installation cavity.

[0009] Further, both ends of the sheet metal panel are folded 180 degrees.

[0010] Further, a groove is formed in the limit clamping plate corresponding to the heating wire.

[0011] Further, the sheet metal panel is made by bending a stainless steel plate.

[0012] A middle column structure of a freezer provided by the utility model has the following beneficial effects:

[0013] 1. Through the cooperation between the shape of the installation cavity and the thermal insulation material, the thermal insulation material made of ordinary thermal insulation foam is convenient to manufacture and install. Then, the heating wire is clamped in the limit clamping plate for heating, and the sheet metal panel and the vertical beam form a metal enclosure, which can resist moisture, increase the structural strength, reduce the steps of assembly, installation and foaming, improve the efficiency and reduce the cost; it solves the problems of many gaps, high processing difficulty and high material cost of the existing combined column.

[0014] 2. The utility model increases the structural strength of the vertical beam through the reinforcing strip, so that it can bear a greater weight without deformation, increases the load-bearing capacity, has a small deformation amount under the same weight, and is more stable during long-term use. During maintenance, the deformed reinforcing strip can be replaced, so that the deformation of the vertical beam can be simply repaired, and the problem of deformation can be solved at a small cost, solving the problem that the existing column needs to replace all the structures after deformation, resulting in high difficulty and high cost.

And during maintenance, the deformed reinforcing bars 4 can be replaced, so that the deformation of the vertical beam 1 can be simply repaired, thus solving the problem of large difficulty and high cost in replacing all the structures after the deformation of the existing columns.

[0026] Both ends of the sheet metal panel 7 are folded 180 degrees; during operation, by folding both ends of the sheet metal panel 7 by 180 degrees, when it is inserted into the gap between the vertical beam 1 and the limit clamping plate 3, the foldable part can be clamped, realizing self-locking insertion into the gap between the vertical beam 1 and the limit clamping plate 3, thus making it difficult to fall off and disengage from the gap between the vertical beam 1 and the limit clamping plate 3, so that the stability during long-term use is higher, solving the problem that the existing combined columns are prone to falling off for a long time.

[0027] A groove is provided in the limit clamping plate 3 corresponding to the heating wire 6; during operation, due to the groove, after the heating wire 6 is installed, it will not protrude from the surface of the limit clamping plate 3, so that the installation of the sheet metal panel 7 is not affected by interference.

[0028] The sheet metal panel 7 is made by bending a stainless steel plate; during operation, the sheet metal panel 7 made by bending a stainless steel plate is convenient for manufacturing and suitable for use in a humid environment, so it has a long service life and is stable.

[0029] Adopting the above scheme, when the utility model is in use, through the cooperation between the shapes of the installation cavity 2 and the heat preservation material 5, the heat preservation material 5 made of ordinary heat preservation foam is convenient for manufacturing and installation. Then, the heating wire 6 is clamped in the limit clamping plate 3 for heating.
