[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Referring to Figures 1 - 5 , a heat-insulating free anti-collision door structure includes a door body 1, an inner frame 2 and an outer frame 3. The inner frame 2 includes a first main frame 4 and a first connecting portion 5, and the first connecting portion 5 is connected to one end of the main frame.

[0026] The outer frame 3 includes a second main frame 6 and two second connecting portions 7. The two second connecting portions 7 are respectively located at both ends of the second main frame 6. A plurality of hole bodies 8 corresponding to the first connecting portion 5 are provided on the first main frame 4.

[0027] Both the first main frame 4 and the second main frame 6 are in an L shape.

[0028] Three hole bodies 8 are provided, and the three hole bodies 8 are equidistantly arranged on the same horizontal line with a spacing of 25 mm.

[0029] The door body 1 is adapted to the outer frame 3.

[0030] When this heat-insulating free anti-collision door is installed on the cold storage panel wall, the inner frame 2 and the outer frame 3 can be installed together. The position of the second connecting portion 7 can be adjusted to be connected to different hole bodies 8 by stretching the distance between the inner frame 2 and the outer frame 3, so as to adapt to cold storage panel walls with three thicknesses of 50 / 75 / 100 mm (as Figure 4 shown), which can reduce and increase production costs and improve installation efficiency. When the thickness of the polyurethane wall panel 15 is greater than 100 mm, only the outer frame needs to be installed alone. First, use aluminum blind rivets to fix the door opening edge banding on the polyurethane wall panel 15, and then use self-tapping screws to fix the aluminum alloy outer frame to the door opening edge banding (as Figure 5 shown).

[0031] In this embodiment, both the first connecting portion 5 and the second connecting portion 7 are arranged in a "concave" shape. A connecting member 9 is movably penetrated through the depths of the concave portions of the first connecting portion 5 and the second connecting portion 7, and a cover plate 10 is embedded on the outer sides of the first connecting portion 5 and the second connecting portion 7. The connecting member 9 is a self-tapping screw, and a hidden nail design is adopted. The self-tapping screws cannot be seen on the front, back, and side of the door frame, and the surfaces of the door panel and the door frame are smooth and clean, preventing dirt accumulation.

[0032] In this embodiment, one of the second connecting portions 7 is arranged opposite to the first connecting portion 5, and the second connecting portion 7 and the first connecting portion 5 are respectively installed on both sides of the wall panel 15 through the connecting member 9, and the other second connecting portion 7 is connected to the hole body 8 through self-tapping screws.

[0033] In this embodiment, the door body 1 includes a polyurethane door panel 11 and a door leaf 12 arranged outside the polyurethane door panel 11. The door panel is produced by a polyurethane foaming process. The overall strength of the door panel is relatively large, with good airtightness and good heat insulation performance. Transverse ribs are provided on the inner wall of the door leaf 12, and the transverse ribs are embedded in the polyurethane door panel 11. The transverse ribs are embedded in the polyurethane foam, playing a very good role in fixed connection and improving the overall strength of the door panel. The material of the door leaf 12 is aluminum alloy. A chute 13 is provided on the door leaf 12, and a sealing strip 14 is slidably arranged in the chute 13, which is convenient for the installation of the sealing strip 14 (compared with the prior art where the sealing strip 14 of the door panel needs to be fixed with a pressing strip and rivets). The other end of the sealing strip 14 abuts against the outer frame 3.

[0034] Embodiment 2

[0035] The difference between this embodiment and Embodiment 1 lies in:

[0036] As Figure 6 shown, in this embodiment, the heat-insulating free anti-collision door is installed on the civil engineering wall. The connecting piece 9 is an expansion screw. In this embodiment, only the outer frame 3 needs to be installed without the inner frame 2. The outer frame 3 is fixed on the civil engineering wall with nylon expansion bolts on the front or side of the outer frame 3. The top of the nylon expansion bolt is an aluminum alloy cover plate 10, and the nylon expansion bolts cannot be seen on the front and side of the outer frame 3.

[0037] The present utility model provides a heat-insulating free anti-collision door, which is customized for the food processing industry and is suitable for installation in a food processing workshop with low temperature and high humidity. It can be installed on both the cold storage board wall and the civil engineering wall, solving the industry problem that traditional heat-insulating free anti-collision doors are not applicable to food processing workshops.

[0038] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
