[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0027] Examples, such as Figures 1-5As shown: This utility model provides a refrigerated cabinet for a spray painting device. The spray painting device is a spray gun (a) used to spray paint from a paint can onto the surface of a workpiece. It comes in two types: one with a lower can (a1) and the other with an upper can (a2). Both types of spray guns (a) have a hook (a3) ​​at their top. In the prior art, the hooks (a3) ​​of the two types of spray guns (a) face opposite directions. The structure includes a cabinet body (1) and a swing-mounted door (2) in front of the cabinet body (1). The inner side of the door (2) where it contacts the cabinet body (1) has a sealing ring. The refrigerated cabinet uses existing refrigerated cabinets or existing refrigeration technology. The operating temperature of the refrigerated cabinet is -150°C to 25°C. C. If the ultra-low temperature refrigeration technology of Guanya Constant Temperature GD-1100-E1-GYZ is adopted, the working temperature can be as low as -150°C. The inner walls on both sides of the cabinet 1 are provided with support steps 11. The support steps 11 are fitted with a placement rack 3 for placing and hanging objects. The placement rack 3 has a structure for hanging spray gun a, so that the hook a3 of spray gun a can be hung on the placement rack 3. At the same time, the spray gun a in the form of lower pot a1 can be placed directly on the placement rack 3. The cabinet 1 is also equipped with a storage tank b, which is used to hold and store the prepared paint liquid. The cabinet 1 or the cabinet door 2 is provided with a one-way valve group 4.

[0028] In this embodiment, the outer surfaces of the cabinet body 1 and the cabinet door 2 have an outer protective layer structure, which is a stainless steel layer or a coating anti-stick layer. In this embodiment, the coating anti-stick layer is a polytetrafluoroethylene layer. The inner surfaces of the cabinet body 1 and the cabinet door 2 have an inner protective layer structure, which is a stainless steel layer or a polytetrafluoroethylene layer, a polyethylene layer, a polypropylene layer, a polyvinyl chloride layer, or a polytetrafluoroethylene layer.

[0029] Specifically, the placement frame 3 includes a plate-shaped flat frame 31. The flat frame 31 is supported on both sides of the support step 11. A horizontal rib 313 is fixed on the flat frame 31. A slot 312 is opened on the flat frame 31. The slot 312 and the front edge of the flat frame 31 form a structure for suspending the spray gun a. In addition, the front edge of the flat frame 31 is provided with an upwardly inclined forward tilting frame 32. The forward tilting frame 32 is provided with a relief groove 311 pointing to the slot 312. The relief groove 311 extends inward from the edge of the forward tilting frame 32 and the inner side is located at the front edge of the flat frame 31. The forward tilting frame 32 and the relief groove 311 can restrict the items placed on the plate and the items suspended on the slot 312.

[0030] Furthermore, an adjusting seat 34 is slidably engaged within the slot 312. The adjusting seat 34 has a locking hole 341 at one end near the front edge of the flat frame 31. The adjusting seat 34 slides on the slot 312 to adjust the distance between the locking hole 341 and the front edge of the flat frame 31, thereby forming a structure for suspending the spray gun a based on the slot 312, thus adjusting the range of suspension of the spray gun a and making the spray gun a more stable.

[0031] In conjunction with this, the adjusting seat 34 is provided with a locking structure to fix the position of the adjusting seat 34 in the slot 312. Specifically, the top of the adjusting seat 34 is provided with a bolt part 342, and a locking nut 35 is threaded onto the bolt part 342. The adjusting seat 34 is fixed by clamping the locking nut 35 and the adjusting seat 34 in the slot 312.

[0032] Specifically, for the one-way valve assembly 4, negative pressure will be generated inside the cabinet during low-temperature freezing. Especially after the surface of the cabinet 1 is covered with a polytetrafluoroethylene layer, the airtightness of the cabinet door 2 and the cabinet 1 will be better. In order to balance the air pressure inside and outside the cabinet, the one-way valve assembly 4 includes a connecting pipe 41 that passes through the cabinet 1. An inner limiting platform 42 is fixedly provided on one side of the connecting pipe 41 inside the cabinet 1 to restrict the outward movement of the connecting pipe 41. A valve plate 43 is oscillating on the inner limiting platform 42. One end of the valve plate 43 is fixedly connected to the inner limiting platform 42. The valve plate 43 has space to swing inward toward the inside of the cabinet 1, so that the one-way valve structure is open in the direction toward the inside of the cabinet 1.

[0033] Furthermore, an adjusting cap 44 is nested on one side of the connecting pipe 41 outside the cabinet 1. Several inner openings 411 are regularly arranged on the side of the connecting pipe 41 outside the cabinet 1. The adjusting cap 44 has an outer opening 441 corresponding to the connecting pipe 41. It should be noted that the distance between adjacent inner openings 411 is greater than the diameter of the inner opening 411. The opening range of the connecting pipe 41 can be adjusted by aligning or intersecting the outer opening 441 on the adjusting cap 44 with the inner openings 411 of the connecting pipe 41. When a negative pressure is generated inside the cabinet 1, the cabinet door 2 will be pressed more tightly against the cabinet 1, thereby compressing the sealing ring. By adjusting the size of the opening of the connecting pipe 41 through the adjusting cap 44, the ease of opening the cabinet door 2 can be adjusted, making it more difficult or taking longer to open the cabinet door 2, thereby reducing the number of times the cabinet door 2 needs to be opened.

[0034] In this embodiment, a side limiting component 33 is movably provided on one side of the flat frame 31 for abutting against the inner wall of the cabinet 1. Specifically, the side limiting component 33 includes a guide part 331, a pressing part 332 and a locking pin 333. The guide part 331 is parallel to the horizontal rib 313. The locking pin 333 is fixedly installed on the guide part 331. The horizontal rib 313 is provided with an inclined inclined pressing groove 314. The guide part 331 is engaged with the inclined pressing groove 314 by the locking pin 333 and then movably engaged with the horizontal rib 313. The pressing part 332 is fixed at the end of the guide part 331 and faces the inner wall of the cabinet 1.

[0035] It should be noted that the horizontal height of the bottom end of the guide part 331 is lower than the horizontal height of the bottom end of the flat frame 31, and the distance between the top end of the inclined pressure groove 314 and the inner wall is less than the distance between the bottom end and the inner wall. The horizontal length of the inclined pressure groove 314 is greater than the gap between the flat frame 31 and the inner wall of the cabinet 1. This allows the bottom end of the guide part 331 to contact the support step 11. When the weight of the placement rack 3 drives the inclined pressure groove 314 to press the locking pin 333 downward, the guide part 331 will push the pressure part 332 against the inner wall of the cabinet 1, thereby locking the placement rack 3 with the cabinet 1 inside the cabinet 1. This prevents the placement rack 3 from being dragged and displaced when the spray gun a is picked up or put down, and also prevents the storage tank b placed on the placement rack 3 from tipping over.

[0036] In this embodiment, the spray gun a is removed from the air pipe, and the relief groove 311 of the spray gun a is inserted into the flat frame 31, so that the hook a3 is suspended on the slot 312 of the placement frame 3. Depending on the model, the size of the hook a3 may vary. At this time, the position of the adjusting seat 34 is moved to adjust the distance between the slot 341 and the front edge of the flat frame 31, so that the slot 341 forms a structure for the spray gun a to be suspended on the basis of the slot 312. This adjusts the range of suspension of the spray gun a to make the spray gun a more stable. As for the uncanned prepared paint liquid, it is poured into the storage tank b, and then the storage tank b is placed on the flat frame 31, so that it can be stored together with the spray gun a.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
