[0019] like Figs. 1 to 4 As shown, a new type of protective structure for a refrigeration unit and the refrigeration unit include a base 1. The base 1 is made of high-strength carbon steel and has a rectangular plate structure. Rubber shock-absorbing pads are provided at the four corners of the bottom to effectively buffer the vibration generated during the operation of the unit and prevent displacement.

[0020] The top of the base 1 is equipped with a refrigeration device 2. The main body of the refrigeration device 2 is an integrated unit of core components such as compressor, condenser, and evaporator encased in a metal shell. The shell is made of high-quality aluminum alloy, which has good heat dissipation and corrosion resistance.

[0021] The front of the refrigeration equipment 2 is hinged with a door 3. The door 3 is made of thick stainless steel plate with a frosted surface. Its shape matches the outline of the front opening of the refrigeration equipment 2. It is a double-opening design and is equipped with a sealing strip. Its sturdy material can resist external impact. When closed, the sealing strip fits tightly against the edge of the equipment to prevent dust and moisture from entering, creating a clean and dry environment for internal components, reducing the failure rate, and making it convenient for operators to open the equipment for debugging, inspection and maintenance.

[0023] The upper portion of the refrigeration equipment 2 is provided with a supporting plate 6, which is mainly punched and formed by thick steel plate and has a rectangular plate structure, and the inner wall clamping groove is accurately designed according to the shape and size of the protective cover 7 and is tightly clamped with the protective cover 7 to provide horizontal support and circumferential limiting for the protective cover 7, so as to ensure accurate and stable protection.

[0024] The inner wall of the supporting plate 6 is clamped with the protective cover 7, which is made of transparent polycarbonate plastic by injection molding, has moderate thickness, high strength and good light transmission, and the top arc design is beneficial to the sliding of foreign matters.

[0025] The inside of the supporting plate 6 is provided with a through groove one 9, and the inside of the protective cover 7 is provided with a through groove two 10.

[0026] The lower portion of the supporting plate 6 is provided with a fixing mechanism 8.

[0027] The fixing mechanism 8 includes two fixed plates 801 fixedly connected to the bottom surface of the supporting plate 6, which are cut and formed by firm steel plate to provide stable support and accurate installation position for the rotation of the rotating shaft 802.

[0028] The inner wall of the fixed plate 801 is rotatably connected with the rotating shaft 802, which is a stainless steel material optical shaft, flexible in rotation and good in corrosion resistance.

[0029] The outer surface of the rotating shaft 802 is fixedly connected with two connecting plates 803, which enhance the structural stability and uniformity of force transmission, so that the positioning plate 806 moves stably and accurately.

[0030] The two ends of the rotating shaft 802 are fixedly connected with one pressing handle 804, which is provided with an arc-shaped recess and conforms to the ergonomic design, so as to be convenient for operation.

[0031] The outer surface of the rotating shaft 802 is sleeved with two torsional springs 805, one end of which is fixedly connected with the outer surface of the fixed plate 801, and the other end of which is fixedly connected with the outer surface of the connecting plate 803, the torsional spring 805 is made of high-elasticity alloy material, the pre-tightening force is accurately adjusted, and in normal state, the elastic force of the torsional spring 805 maintains the positioning plate 806 penetrating through the through groove one 9 and the through groove two 10 to lock the protective cover 7, so as to ensure the protection to be stable; when the protective cover 7 is replaced, the pressing handle 804 overcomes the elastic force of the torsional spring 805 to rotate the rotating shaft 802 and drive the positioning plate 806 to separate from the through groove one 9 and the through groove two 10, so as to realize quick and convenient replacement, effectively improve the equipment maintenance efficiency, reduce the maintenance cost and downtime, and ensure the timely recovery of the protection function.

[0032] The outer surface of the rotating shaft 802 is fixedly connected with the positioning plate 806, and one end of the positioning plate 806 away from the rotating shaft 802 penetrates through the through groove one 9 and the through groove two 10 and extends into the inside of the protective cover 7.

[0033] The upper portion of the refrigeration equipment 2 is provided with a buffer mechanism 5.

[0034] The buffering mechanism 5 comprises a limiting cylinder 501 fixedly connected to the upper surface of the refrigeration device 2, which is processed from a steel pipe, the inner wall of which is finely ground to ensure smooth sliding of the moving column 502, and the outer part can be reinforced with a rib plate to enhance the structural strength.

[0035] The moving column 502 is slidably connected to the inner wall of the limiting cylinder 501, and one end of the moving column 502 is fixedly connected to the bottom surface of the supporting plate 6. The moving column 502 is a solid alloy steel column, and one end thereof is stably welded to the supporting plate 6 to transmit impact force.

[0036] The other end of the moving column 502 is fixedly connected to the elastic member 503, and the end of the elastic member 503 away from the moving column 502 is fixedly connected to the inner wall of the limiting cylinder 501. The elastic member 503 is a high-strength spiral spring, and the elastic coefficient thereof is accurately matched with the weight and impact characteristics of the unit. When the protective cover 7 is impacted by external force, the impact force is transmitted to the moving column 502 through the supporting plate 6, so that the moving column 502 rapidly slides downward in the limiting cylinder 501 to compress the elastic member 503. The spring deformation absorbs energy to buffer and dampen, greatly reducing the damage of impact to the refrigeration device 2, and protecting the equipment and internal precision components.

[0037] Working principle: when in operation, the refrigeration device 2 normally operates to realize the refrigeration function, the box door 3 is convenient for operation and maintenance, the ventilation net 4 ensures the air circulation between the inside and outside, helps heat dissipation, and maintains the stable environment of the equipment. When the protective cover 7 is impacted by external force, the impact force is transmitted to the supporting plate 6 through the protective cover 7, the moving column 502 in the buffering mechanism 5 slides downward in the limiting cylinder 501, the elastic member 503 deforms to absorb energy and dampen, thereby protecting the refrigeration device 2 below. In the fixing mechanism 8, the torsional spring 805 makes the positioning plate 806 normally inserted into the through slot one 9 and the through slot two 10, so that the positioning of the protective cover 7 can be realized. When the protective cover 7 needs to be replaced, the pressing handle 804 is pressed downward to drive the rotating shaft 802, the connecting plate 803 and the positioning plate 806 to rotate clockwise, and at the same time, the torsional spring 805 deforms. At this time, the positioning plate 806 is separated from the through slot one 9 and the through slot two 10, so that the positioning of the protective cover 7 can be released. The protective cover 7 can be taken off from the supporting plate 6 by pulling it forward or backward, then a new cover is inserted into the supporting plate 6, the pressing handle 804 is released, the torsional spring 805 is reset and inserted into the through slot one 9 and the through slot two 10, so that the protective cover 7 can be quickly disassembled, which saves time and effort and improves the maintenance and replacement efficiency of the protective cover 7.
