Description

Technical Field

[0001] The utility model relates to the field of containers, in particular to a container refrigeration machine sealing plate structure. Background Art

[0002] The market has different demands for refrigeration units. Sometimes, refrigeration units are installed directly in containers at the refrigeration factory, which results in the refrigeration unit opening being exposed. If the container is not protected during transportation, pollutants such as rain, dust, and garbage will be blown into the interior of the container during inclement weather. To avoid this, the location where the refrigeration unit is installed needs to be sealed with a plate. The existing solution generally uses rivets on the front frame to fix the sealing plate to the container, which can easily cause certain damage to the container, affecting the container's thermal insulation performance and, in turn, the overall customer experience. At the same time, the existing solution uses 1.2mm thick color-coated steel plates to resist deformation of the flat plate, which is relatively heavy and expensive. Summary of the Invention

[0003] The purpose of the utility model is to provide a container refrigeration machine sealing plate structure to solve the problems raised in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a container refrigeration machine sealing plate structure, comprising a sealing plate and a Z-shaped connector, the periphery of the sealing plate being fixed to the front frame of the container by a plurality of spaced-apart Z-shaped connectors, the depth dimension of the Z-shaped connector being smaller than the foaming thickness of the front frame, one side of the Z-shaped connector being connected to the sealing plate by rivets, and the other side being snapped onto the front frame with a smaller depth dimension, and the sealing plate being tightened to the front frame by means of extrusion force.

[0005] Preferably, the Z-shaped connector includes a first vertical portion, a horizontal portion, and a second vertical portion connected in sequence, and the distance between the first vertical portion and the second vertical portion is the depth dimension of the Z-shaped connector; the front frame includes an outer side surface of the box, an inner side surface of the frame, and an inner side surface of the box, and the distance between the outer side surface of the box and the inner side surface of the box is the foaming thickness of the front frame; the sealing plate, the inner side surface of the frame and the inner side surface of the box form a Z-shaped structure, the second vertical portion and the sealing plate are connected by rivets, and the angle between the horizontal portion and the first vertical portion is snapped to the angle between the inner side surface of the frame and the inner side surface of the box.

[0006] Preferably, the sealing plate is square, and all four sides have bent edges, and the bent edges are perpendicular to the body of the sealing plate.

[0007] Preferably, the sealing plate is a color steel plate with a thickness of 0.7 mm.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The present invention utilizes the Z-shaped structure formed between the front frame and the cover plate of the container, and adopts a Z-shaped connector to fix the cover plate to the front frame, avoiding drilling holes in the front frame, ensuring the thermal insulation performance of the front frame, and making the exterior more beautiful; at the same time, the depth of the Z-shaped connector is slightly smaller than the foam thickness of the front frame, thereby generating a certain amount of extrusion, making it easy to tighten the cover plate to make it fit closely to the front frame while the Z-shaped connector is snapped onto the front frame.

[0018] The present invention discloses a container refrigeration machine sealing plate structure, comprising a sealing plate 1 and a Z-shaped connector 2. The periphery of the sealing plate 1 is fixed to the front frame 3 of the container by a plurality of Z-shaped connectors 2 arranged at intervals. Figures 1 to 3 , the specific structure is as follows:

[0019] Combine Figure 4 The Z-shaped connector 2 includes a first vertical portion 21, a horizontal portion 22 and a second vertical portion 23 that are sequentially connected and integrally formed. The first vertical portion 21 and the second vertical portion 23 are both perpendicular to the horizontal portion 22, and the transition between the three is arc-shaped.

[0020] The present invention does not improve the container and its front frame 3. The related structures all adopt the existing technology. The specific structure of the front frame 3 is not described in detail in this embodiment. Only the three-side structure of the frame is used as auxiliary explanation. Figure 5 The front frame 3 includes an outer side 31, an inner side 32, and an inner side 33. The outer side 31 is the side of the front frame 3 facing the outside of the box, and the inner side 33 is the side of the front frame 3 facing the inside of the box. Both the outer side 31 and the inner side 33 are perpendicular to the inner side 32. The transition between the outer side 31 and the inner side 32 is arc-shaped, while the transition between the inner side 33 and the inner side 32 is at a right angle.

[0021] The sealing plate 1, the inner side surface 32, and the inner side surface 33 of the box form a Z-shaped structure that corresponds exactly to the shape of the Z-shaped connector 2. The distance between the first vertical portion 21 and the second vertical portion 23 is the depth of the Z-shaped connector 2, and the distance between the outer side surface 31 and the inner side surface 33 is the foam thickness of the front frame 3. The depth of the Z-shaped connector 2 is less than the foam thickness of the front frame 3.

[0022] When the two Z-shaped structures mate, the Z-shaped connector 2 exerts a compressive force on the sealing plate 1 and the front frame 3. The second vertical portion 23 of the Z-shaped connector 2 is connected to the sealing plate 1 via rivets, running nearly parallel to the sealing plate 1. The horizontal portion 22 is in direct contact with the inner side surface 32 of the frame, and the first vertical portion 21 is in nearly parallel contact with the inner side surface 33 of the box. This ensures that the angle between the horizontal portion 22 and the first vertical portion 21 is locked to the angle between the inner side surface 32 of the frame and the inner side surface 33 of the box. Based on this structure, the Z-shaped connector 2 is fixed to the sealing plate 1 on one side, while the other side, with its smaller depth dimension, is locked to the front frame 3, relying on the compressive force to pull the sealing plate 1 tight against the front frame 3.

[0023] The cover 1 is typically constructed of color-coated steel sheet in a square shape. To reduce its thickness and weight, this embodiment features four bent edges 11. These edges are perpendicular to the body of the cover 1 and face the exterior of the box. These edges increase the strength of the cover 1, making it resistant to deformation. They also reduce the thickness of the color-coated steel sheet to 0.7mm, resulting in a lighter weight and lower cost. Silicone gel 5 is bonded to the seam between the bent edges 11 and the exterior surface 31 of the front frame 3, providing a seal.

[0024] To meet the requirements of use, a single-sided insulating tape 4 is bonded to the side of the sealing plate 1 that contacts the front frame 3, and a single-sided insulating tape 4 is bonded to the side of the Z-shaped connector 2 that contacts the sealing plate 1, that is, a single-sided insulating tape 4 is bonded to the square ring contact portion of the sealing plate 1 facing the front frame 3, and a single-sided insulating tape 4 is bonded to the second vertical portion 23 of the Z-shaped connector 2.

[0025] The general implementation process of the above structure is as follows: first, stick the single-sided insulating tape 4 on the sealing plate 1 and the end of the Z-shaped connector 2, then the staff outside the box positions the sealing plate 1 to the appropriate position, and then the staff inside the box fixes the Z-shaped connector 2 on the sealing plate 1 with rivets, and at the same time snaps the Z-shaped connector 2 to the front frame 3, and finally installs multiple Z-shaped connectors 2 in sequence according to the steps of riveting first and then snapping.

[0026] In summary, the utility model uses the Z-shaped structure formed between the front frame 3 of the box and the closing plate 1, and uses a Z-shaped connector 2 to rely on the extrusion force to tighten the closing plate 1 to the front frame 3. This method does not require rivets on the front frame 3 and will not cause damage to the box. It has a certain aesthetic appeal and also ensures the thermal insulation performance of the front frame 3; at the same time, bending at each end of the closing plate 1 can increase the strength of the closing plate 1 and resist deformation, thereby reducing the thickness of the closing plate 1, making it lighter, and reducing costs and labor intensity.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
