Description

Technical Field

[0001] The utility model belongs to the technical field of light box cover plates, and in particular relates to a novel door light box cover plate structure. Background Art

[0002] At present, most of the refrigeration equipment involving air-cooled glass doors, such as frozen display cabinets and vertical freezers, have integral glass doors. For vertical air-cooled frozen display cabinets, especially those with the evaporator at the top of the cabinet, the front of the top of the cabinet is generally treated as a foaming structure to ensure energy efficiency and other reasons. In the context of this cabinet structure, the front appearance structure is traditionally three-stage, i.e., the upper light box structure, the middle glass door body, and the lower front cover structure. However, with the upgrading and iteration of products, the traditional three-stage appearance structure has gradually lost the favor of consumers. The current common new appearance structure is a two-stage structure, i.e., a glass door body plus a lower front cover structure. This appearance structure is mostly used in refrigerated cabinets with open cabinet structures (structures without an insulation layer at the top front of the cabinet), and the glass door is still integral, fully covering the front opening of the cabinet. For the above two-stage display cabinet, the door light box cover is generally fixed with all screws, and the LED light strip is fixed by designing several bumps on the back of the door light box cover, and the bumps are connected to the round holes on the light strip; however, the door light box cover is fixed with all screws, which increases the working hours and is not beautiful overall. The LED light strip is fixed by the bump-on-round hole method, which has high requirements for mold design. Utility Model Content

The left, right and upper outer circles of the door light box cover body 1 have a total of 8 notches, which are door body shell claw clearance notches 3, and a number of screw holes 4 are provided near the left, right and upper outer circle notches. The screw holes in this patent are countersunk screw fixing holes or pan head screw fixing holes.

[0036] like Figure 3 , 4As shown in Figure 6, the support buckle structure 5, the wire fixing card structure 6 and the card slot structure 7 are arranged on the back side of the door light box cover body 1, and the support buckle structure 5 is connected to the LED light strip 13; the support buckle structure 5 and the wire fixing card structure 6 are located in the middle of the door light box cover body 1, and the wire fixing card structure 6 is located on both sides of the support buckle structure 5, and the card slot structure 7 is located at one end of the door light box cover body 1 close to the door body 14.

[0037] The support buckle structure 5 is divided into two rows by the transverse ribs 9, and each row is provided with N groups of support buckles, and each group of support buckles includes two T-shaped ribs 51 and two support buckle inverted buckle structures 52; the T-shaped ribs 51 are arranged horizontally and inverted on the door light box cover body 1, and the T-shaped ribs 51 of each row are parallel and located at the same height; the support buckle inverted buckle structures 52 are arranged on one side of the T-shaped ribs 51, and are staggered. The LED light bar 13 is connected to the support buckle structure 5, and there is a matching gap between the LED light bar 13 and the T-shaped ribs 51 and the support buckle inverted buckle structures 52. The support buckle structure 5 is used to realize the fixation of the LED light bar 13 on the door light box cover body 1, involving the fixation of the three directions of up and down, left and right, and front and back. This support buckle structure 5 only involves the fixation of the LED light bar 13 in the up and down and front and back directions. In the up and down directions, the lower support and the upper buckle are realized by the T-shaped ribs 51 of the support buckle structure 5 and the support buckle inverted buckle structure 52. For the front and rear directions, it is achieved by arranging T-shaped ribs 51 and supporting buckle inverted buckle structures 52 in a row; in each group of supporting buckles, the T-shaped ribs 51 can be exactly the same, while the supporting buckle inverted buckle structures 52 are relatively staggered, and the front and rear fixation of the LED light strip 13 is achieved by the relatively staggered supporting buckle inverted buckle structures 52.

[0038] The height of the T-shaped rib 51 is the fixed height of the LED light strip 13 on the door light box cover body 1, the upper end face 512 of the T-shaped rib is a plane, the length of the T-shaped rib transverse rib 511 is close to or greater than or equal to the width of the LED light strip 13, and the length of the vertical rib below the T-shaped rib 51 can be made longer if the mold allows.
