[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A portable, multi-functional upright freezer, comprising:

[0007] Vertical freezer body;

[0008] Two cabinet doors, both of which are movably hinged to the inner surface of the vertical freezer body, and a fixed base and mounting frame are fixedly connected to the inner surface of the vertical freezer body.

[0009] The winding mechanism includes:

[0010] A storage slot is provided on one inner wall of the mounting frame. A winding rod is rotatably connected to the inner surface of the storage slot. A spacer plate is sleeved on the outer surface of the winding rod. The outer surfaces of the two spacers plate are fixedly connected to the inner surface of the storage slot.

[0011] Two first spiral springs are fixedly connected to the circumferential surface of the winding rod. One end of each first spiral spring is fixedly connected to one inner wall of the receiving groove. A blocking rope is provided on the circumferential surface of the winding rod.

[0012] A snap-fit ​​mechanism is provided inside the vertical freezer body and connected to the barrier rope to snap and fix the elongated barrier rope.

[0013] As a preferred embodiment of this utility model, the snap-fit ​​mechanism includes:

[0014] A sliding groove is formed on the inner wall of the other side of the mounting frame. A snap-fit ​​groove is formed on one side of the inner wall of the sliding groove. A sliding seat is slidably connected to the inner surface of the sliding groove. One end of the sliding seat is fixedly connected to one end of the barrier rope.

[0015] A lower pressure groove is formed at the upper end of the sliding seat. A lower pressure plate is slidably connected to the inner surface of the lower pressure groove. A lower pressure rod and a locking block are fixedly connected to the upper end of the lower pressure plate. The outer surface of the locking block and the inner surface of the locking groove are slidably connected.

[0016] An elastic component is disposed within a pressure groove to support and limit the sliding pressure plate.

[0017] As a preferred embodiment of this utility model, the elastic component includes:

[0018] Two limiting seats are fixedly connected to the lower inner wall of the lower pressure groove, and a limiting spring is sleeved on the outer surface of each of the two limiting seats.

[0019] As a preferred embodiment of this utility model, an installation shell is fixedly connected to the inner surface of the vertical freezer body, a rotating rod is rotatably connected to the inner surface of the installation shell, and two support seats are sleeved on the outer surface of the rotating rod. The outer surfaces of the two support seats and the inner surface of the installation shell are fixedly connected.

[0020] In a preferred embodiment of this utility model, a blocking curtain and two second spiral springs are fixedly connected to the circumferential surface of the rotating rod. One end of each of the two second spiral springs is fixedly connected to the inner wall of one side of the mounting shell, and a drop plate is fixedly connected to one end of the blocking curtain.

[0021] As a preferred embodiment of this utility model, the upper end of the fixed base is provided with multiple limiting grooves, and the inner surfaces of the multiple limiting grooves are slidably connected to limiting blocks, and the upper ends of the multiple limiting blocks are respectively fixedly connected to two handles.

[0022] As a preferred embodiment of this utility model, a pressure cap is fixedly connected to the upper end of the pressure rod.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. In this solution, by pulling the free end of the barrier rope, the winding rod rotates counterclockwise within the storage slot, simultaneously stretching the first spiral spring to store elastic potential energy. The barrier rope unfolds from the winding rod. As the barrier rope is pulled out, the sliding seat slides horizontally to the desired position within the sliding slot. The user presses the lower cap, which pushes the lower pressure plate to compress the limiting spring via the lower pressure rod, causing the locking block to descend and embed into the locking slot, locking the sliding seat position. The barrier rope remains stretched, thus blocking the items inside the freezer. During the movement of the upright freezer, the beverages and items placed inside are blocked and limited, solving the problem of slippage or falling during movement. This avoids damage and spillage to the surface of beverages and items, while also protecting the interior of the freezer from impacts that could cause cracks in the inner wall, thereby reducing the waste of resources and manpower.

[0025] 2. In this solution, by pulling down the drop plate, the blocking curtain is driven to unfold from the rotating rod. The rotating rod rotates counterclockwise and stretches the second spiral spring to store elastic potential energy. The blocking curtain hangs vertically down into the interior of the fixed base. Pulling the two handles fixes the drop block, thus preventing external sunlight from shining into the interior of the freezer. Attached Figure Description

At the same time, the first spiral spring 9 is stretched to store elastic potential energy, and the barrier rope 10 unfolds from the winding rod 7. As the barrier rope 10 is pulled out, the sliding seat 13 slides horizontally to the desired position in the sliding slot 11. The user presses down the cap 16, which pushes the lower pressure plate 17 through the lower pressure rod 15 to compress the limit spring 20, causing the locking block 18 to descend and embed into the locking slot 12, locking the sliding seat 1. At position 3, the barrier rope 10 remains stretched to prevent items inside the freezer from falling during movement or handling. Simultaneously, the user pulls down the drop plate 3, causing the barrier curtain 28 to unfold from the rotating rod 22. The rotating rod 22 rotates counterclockwise and stretches the second spiral spring 24 to store elastic potential energy. The barrier curtain 28 hangs vertically down into the fixed base 4. Pulling the two handles 25 fixes the drop plate 3, thus forming a physical separation layer, reducing cold air convection, and preventing external sunlight from shining into the freezer.
