Adjustable middle beam draw bar connecting structure for display refrigerator

Abstract

The invention discloses an adjustable middle beam draw bar connecting structure for a display refrigerator. The adjustable middle beam draw bar connecting structure comprises a refrigerator inner container, a refrigerator shell, an opening and a middle beam draw bar. The refrigerator shell is mounted on the outer side of the refrigerator inner container, refrigerator fillers are arranged between the refrigerator shell and the refrigerator inner container, the opening is fixedly formed in the refrigerator inner container and the refrigerator shell, two ends of the middle beam draw bar are respectively fixed onto two inner side walls of the opening, and a glass door is arranged on the opening. The adjustable middle beam draw bar connecting structure is characterized in that external threads are arranged at the ends of the middle beam draw bar, and the ends of the middle beam draw bar penetrate the inner side walls of the opening from the front surfaces of the inner side walls of the opening and are locked on the opening by fasteners with threaded holes. Compared with the prior art, the adjustable middle beam draw bar connecting structure has the advantages that the adjustable middle beam draw bar connecting structure is simple and reasonable, the matching size of the opening can be adjusted, accordingly, problems in actual usage and assembly can be solved, and the adjustable middle beam draw bar connecting structure is firm.

Description

technical field [0001] The invention relates to an adjustable center beam pull rod connection structure for displaying a refrigerator. Background technique [0002] At present, with the improvement of people's living standards, various large-scale commercial refrigerated and frozen display cabinets have also entered major supermarkets and stores. The cabinet body of this kind of display cabinet is generally relatively large, and the insulation layer of the cabinet body will be deformed under the action of a long-term cold and hot environment. In most cases, it will bulge to both sides of the cabinet body, commonly known as "big belly". , causing the gap between the upper glass door body and the cabinet mouth to become larger, causing air-conditioning to leak out. Severe deformation even makes the upper glass fall under the cabinet mouth, causing the product to not be used normally. The above situation has been a long-term problem for sellers and manufacturers, and it is al...
