Opening frame and box matching structure of food refrigeration display cabinet

Abstract

An opening frame and box matching structure of a food refrigeration display cabinet belongs to the technical field of refrigerating devices. An opening frame comprises an opening frame body, and a box slot is formed in the opening frame body. The box comprises a box body, and the box body comprises an inner container, a casing and a foaming heat insulation layer. The matching structure is characterized in that an opening frame matching fold side is bended on one side of the fold side of the casing facing the opening frame body, the opening frame matching fold side is bended to form an inclined fold side in the direction backing to the foaming heat insulation layer, the inclined fold side is bended to form a clamping leg limit fold side towards one side of the opening frame matching fold side backing to the foaming heat insulation layer, and a slot is formed in the space between the clamping leg limit fold side and the opening frame matching fold side. One side of the opening frame body facing the casing fold side is bended to form a casing matching fold side, and one side of the casing matching fold side facing an opening frame embedding leg cavity is bended to form an opening frame embedding leg. The structure effectively prevents foaming materials from escaping to the external from a gap between the casing matching fold side and the casing fold side. The assembly is simplified, the operation intensity is light, the assembly efficiency is high, stress is even, and the whole combination effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of refrigeration devices, and in particular relates to a cooperation structure between an opening frame and a box body of a food refrigerated display cabinet. Background technique [0002] Since food refrigerated display cabinets not only have the function of keeping food cold and fresh, but also have the advantage of displaying food to customers, they are widely used in shopping malls, supermarkets, restaurants and even public places (such as stations and airports). The food refrigerated display cabinet usually consists of upper, middle and lower parts. The upper part is a light box, which is used for advertising, the middle part is the cabinet body, which is the part of the refrigerator box, which is used to refrigerate all kinds of food, and the lower part is the host of the refrigeration system. Such as the location of the compressor, and it is shielded by the lower trim. [0003] As known in the indus...

Problems solved by technology

[0005] above by image 3 The matching structure between the mouth frame and the box body of the food refrigerated display cabinet shown has the following technical problems: First, because the box slot 11 of the mouth frame body 1 is fitted (mated) with the edge of the shell 22 or There are more or less gaps, that is to say, there is an irreversible gap between the mating parts of the shell and the box slot 11, so during the foaming process, the foam material constituting the foam insulation layer 23 will escape from the gap to the outside , resulting in poor sealing and heat preservation of the mouth frame body 1. When the food refrigerated display cabinet is in use, dew condensation occurs on the mouth frame body 1 and energy saving is lost; secondly, in order to artificially prevent the foaming material from The position where the box slot 11 of the mouth frame body 1 is mated with the housing 22 escapes to the outside world, so after the housing 22 is mated with the box slot 11, an adhesive tape is pasted on the mating position, and the adhesive tape The gap is blocked, so it causes troublesome operation, which not only increases the work intensity of the workers, but also wastes the adhesive tape as an auxiliary material; third, because the structure of the mouth frame body 1 is unreasonable, it needs to be assembled with the box body 2 piece by piece , thus not only affecting the overall assembly effect, but also low work efficiency; Fourth, since the mouth frame body 1 needs to be assembled piece by piece, it is difficult to ensure the uniform force effect of the assembled mouth frame body 1, for example, there is a risk of arching
