[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] See also Figures 1 to 6 The utility model provides a technical solution: a double-layer 3-tray thermal insulation cabinet, including a cabinet body 1, an upper thermal insulation chamber 2 and a lower thermal insulation chamber 3 are provided in the cabinet body 1, two upper trays 4 are provided in the upper thermal insulation chamber 2, the upper thermal insulation chamber 2 provides thermal insulation temperature for the food on the upper tray 4, the lower thermal insulation chamber 3 is provided with a lower tray 5 and a slag receiving tray 6 located below the lower tray 5, the lower thermal insulation chamber 3 provides thermal insulation temperature for the food on the lower tray 5, and two types of food with different thermal insulation temperature requirements are placed in the upper thermal insulation chamber 2 and the lower thermal insulation chamber 3 respectively, which is convenient for classified insulation.

[0027] Support plates 11 are provided at the rear on both sides of the cabinet body 1, and the support plates 11 serve as support beams. Transparent glass is provided on the cabinet body 1 to enclose the upper insulation cavity 2 and the lower insulation cavity 3, so as to facilitate the display of food on the upper tray 4 and the lower tray 5.

[0028] Further, the side of the support plate 11 is provided with transverse insertion grooves 111 which are located in the upper heat preservation cavity 2 and are uniformly distributed along the height direction. The side of the support plate 11 is provided with sliding grooves 112 which are distributed upwards and downwards and are located on one side of the uniformly distributed transverse insertion grooves 111. The sliding grooves 112 are close to the inside. The positioning bolt 7 is slidably connected to the sliding grooves 112. The positioning bolt 7 is screwed with the locking nut 8. When the locking nut 8 is screwed, the positioning bolt 7 is locked on the support plate 11. When the locking nut 8 is loosened, the positioning bolt 7 can easily slide upwards and downwards along the sliding grooves 112. The bottom of the upper tray 4 is fixedly connected with a supporting shaft 41 which is close to one end. The both ends of the supporting shaft 41 extend into the transverse insertion grooves 111 and are detachably connected. The upper tray 4 is rotatably connected with the transverse insertion grooves 111 through the supporting shaft 41. The bottom of the upper tray 4 is in contact with the positioning bolt 7. The inclination angle of the upper tray 4 can be adjusted by adjusting the position of the positioning bolt 7. The height of the upper tray 4 can be adjusted by replacing the supporting shaft 41 and the different transverse insertion grooves 111. This arrangement facilitates the more comprehensive display of food on the upper tray 4.

[0029] The sliding groove 112 is a T-shaped groove structure. The positioning bolt 7 is a T-shaped bolt and the large end of the positioning bolt 7 is located in the sliding groove 112. When the locking nut 8 is screwed, the positioning bolt 7 is pressed and fixed on the support plate 11.

[0030] In this embodiment, one end of the transverse insertion groove 111 is in communication with the side of the support plate 11 which is away from the upper heat preservation cavity 2. This arrangement facilitates the replacement of the supporting shaft 41 with other transverse insertion grooves 111. That is, when the supporting shaft 41 slides outward, it can slide out of the transverse insertion groove 111. The upper tray 4 is connected with the lamp holder 9 through the groove-shaped hanging bracket 42. The bottom of the lamp holder 9 is provided with a light bar. The detachable connection between the lamp holder 9 and the upper tray 4 facilitates the disassembly and cleaning of the upper tray 4. The bottom of the upper heat preservation cavity 2 and the top of the lower heat preservation cavity 3 are provided with lamp holders 9. The lamp holders 9 are used for illuminating the food in the upper heat preservation cavity 2 and the lower heat preservation cavity 3.

[0031] Further, the cabinet 1 is provided with an upper heat preservation cotton 101 which separates the lower heat preservation cavity 3 and the upper heat preservation cavity 2. The upper part of the upper heat preservation cotton 101 is provided with a heating pipe 102. The heating pipe 102 heats the upper heat preservation cavity 2 after being electrified. The bottom of the lower heat preservation cavity 3 is provided with a lower heat preservation cotton 103. The upper part of the lower heat preservation cotton 103 is provided with a heating pipe 102. The heating pipe 102 heats the lower heat preservation cavity 3 after being electrified. The lamp holder 9 in the lower heat preservation cavity 3 is fixedly connected with the bottom of the upper heat preservation cotton 101.

[0032] In this embodiment, the bottom of the upper heat preservation cavity 2 is fixedly provided with a support plate 31 which penetrates the lower heat preservation cotton 103. The slag receiving tray 6 is located above the heating pipe 102 and the bottom of the slag receiving tray 6 is in abutment with the support plate 31. The inner wall of the upper heat preservation cavity 2 is fixedly connected with a cushion 32 which is used for lifting the lower tray 5. This facilitates the direct taking and placing of the lower tray 5 and the slag receiving tray 6.

[0033] Furthermore, a control panel 104 is provided at the bottom of the rear side of the cabinet 1. The control panel 104 is electrically connected to the heating tube 102 and the lamp holder 9. A temperature control switch module for adjusting the temperature and a plug connected to an external power cord are provided on the control panel 104.

[0034] In this embodiment, a double door 105 is provided on the rear side of the cabinet body 1, which is opposite to the lower insulation chamber 3 and the upper insulation chamber 2 respectively. Transparent glass is provided inside the double door 105. The double door 105 adopts a common hinged shaft rotation opening and closing structure. After the double door 105 is opened, it is convenient to operate the upper tray 4, the lower tray 5 and the slag receiving tray 6.

[0035] Working principle: During use, when the tilt angle of the upper tray 4 needs to be adjusted, manually lift the upper tray 4, then loosen the locking nut 8, slide the positioning bolt 7 up and down, so that the upper tray 4 can be in a position to fully display the food thereon, and then tighten the locking nut 8. At this time, the position of the positioning bolt 7 is fixed and supports the upper tray 4, and then the insulation temperature in the upper insulation chamber 2 and the lower insulation chamber 3 is adjusted through the temperature control switch module on the control panel 104, and the upper insulation chamber 2 and the lower insulation chamber 3 are separately kept warm at different temperatures.

[0036] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
