[0029] Figure 1 This is a schematic diagram of the structure of the present invention. Figure 1 ;

[0030] Figure 2 This is a schematic diagram of the structure of the present invention. Figure 2 . Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Example 1:

[0033] Please see Figure 1-2 This utility model provides a technical solution:

[0034] A refrigeration sealing structure for cold storage includes a door frame mounting plate 2, a long plate 1 installed on one side of the door frame mounting plate 2, and a short plate 3 installed on the other side. In order to realize the linkage of the structure, a driving structure is installed on the inner side of the long plate 1 to drive the movement of the entire structure. In order to facilitate the operation of the structure, the driving structure is connected to an external crank 4, and the movement is realized by rotating the crank.

[0035] To achieve stability during transmission, at least three sets of linkage structures are provided at the bottom of the door frame mounting plate 2. The driving structure is hinged to the linkage structure close to itself through the linkage rod 8 to drive the linkage structure. The linkage structures are linked together through the long rod 11 to achieve mutual cooperation. A fixing structure is installed on the inner side of the short plate 3, and the fixing structure is connected to the linkage structure close to itself through the short rod 13.

[0036] The door frame mounting plate 2, long plate 1, and short plate 3 are all made of stainless steel, which maintains strength and stability during long-term use and is not easily damaged.

[0037] like Figure 1 As shown:

[0038] The drive structure consists of a mounting bracket 5, a crankshaft 6, and a triangular connecting ear 7. The mounting bracket 5 is fixed to the inside of the long plate 1. In order to achieve drive, one end of the crankshaft 6 is connected to the crank 4, one end of the triangular connecting ear 7 is inserted into the mounting bracket 5, and the other end of the crankshaft 6 is passed through the mounting bracket 5 and the triangular connecting ear 7, and the three are hinged together.

[0039] When the crankshaft 6 rotates, it drives the mounting bracket 5 and the triangular connecting lug 7 to rotate accordingly, and the other end of the triangular connecting lug 7 is hinged to the connecting rod 8. When the crankshaft 6 rotates, it drives the connecting rod 8 to move.

[0040] like Figure 1 As shown:

[0041] The linkage structure consists of a top frame 9 and a vertical rod 10. For easy installation, the top frame 9 is fixed to the bottom of the door frame mounting plate 2. The top frame 9 is hinged to one end of the vertical rod 10. The vertical rod 10 near the linkage rod 8 is hinged to the linkage rod 8 to enable mutual rotation between the components.

[0042] At the same time, the vertical rods 10 are hinged together by long rods 11, connecting the linkage structures to achieve a linkage effect.

[0043] like Figure 1-2 As shown:

[0044] A stabilizing frame 12 is hinged to one side of the vertical rod 10 for connecting the door body. The fixing structure consists of a side reinforcing frame 51, a top reinforcing frame 91, and an auxiliary vertical rod 101. For easy installation, the side reinforcing frame 51 is fixed to the inside of the short plate 3, and the top reinforcing frame 91 is fixed to the bottom of the door frame mounting plate 2.

[0045] Meanwhile, the auxiliary vertical rod 101 is hinged to the side reinforcement frame 51 and the top reinforcement frame 91 respectively. In order to achieve the overall linkage, the short rod 13 is hinged to the auxiliary vertical rod 101.

[0046] Operating principle:

[0047] When crank 4 rotates, it drives the triangular connecting lug 7 and connecting rod 8 to rotate through crank shaft 5. Connecting rod 8 drives the long rod 11 connected to it to move, retracting or pushing forward.

[0048] Since the stabilizer 12 is connected to the door, the stabilizer 12 connected to the vertical rod 10 drives the door to retract or push forward, which can achieve a tight seal with the sealing strip on the door, realize the opening and closing of the cold storage door, and prevent cold air from escaping.

[0049] Its specific principle is as follows:

[0050] The key fulcrum and drive point of the linkage mechanism are fixed to the door leaf to form a rigid transmission system. The crank and its shaft are vertically installed at a specific position on the door leaf (usually near the door edge) through a sturdy frame or bushing. This installation point forms the fixed fulcrum (point O) for the rotation of the linkage, ensuring that the rotation is stable with the door leaf as the reference.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
