Problems solved by technology

[0002] As known, refrigerators are widely used as storage containers for storing food or objects with low-temperature storage requirements in homes, hotels, and hospitals. However, most of the handles on the doors of refrigerators are fixed structures. The corresponding magnet on the body is used as a door stopper for closing the door. After each use, the door needs to be pushed tightly to completely close the door and the cabinet body. Only the sealing strip embedded on the door and the cabinet body can play a role in preventing the loss of cold air. Purpose; but many people close the refrigerator after using it, and leave without confirming whether the door is completely closed, causing a large wave of cold air to be lost, and eventually causing food to deteriorate or melt
[0003] There are a variety of electromagnetic devices on the market to close the door by induction, but due to the impact of durability, after many years of use, it usually happens that the door cannot be pulled or the button of the electric device cannot be pressed; this is because the door handle of the refrigerator is restricted. Due to the following special requirements, that is, the handle should be supported by easy and labor-saving opening. If the door of the refrigerator is opened, the refrigerator door can only be opened under very difficult conditions; that is to say, it is obviously not suitable to use mechanical locks; When the magnet strip is used as a door stopper, usually when the magnet is closed, the refrigerator door will be sucked in the closed position, which is not only caused by the locking force of the magnetic seal, but also mainly by the high adsorption caused by the vacuum caused by air cooling caused by force, making it extremely inconvenient to use

Abstract

The invention discloses an automatic door-closing rotary-screwing type handle of a magnetic-attraction refrigerator and relates to a handle of a refrigerator door. A screw of a rotary-screwing handle (8) penetrates through a fixed ring, an adjusting spring (6) and a ring in sequence and is locked by a nut (2); two ends of a return spring (15) are respectively connected with the outer end of a J-shaped spring seat and the other end of a C-shaped seat; a powerful magnet B arranged on the C-shaped seat faces to one side of a door frame of a box body (18); and the plate wall of the door frame of the box body, which corresponds to the powerful magnet B, is provided with a powerful magnet A (16). The automatic door-closing rotary-screwing type handle disclosed by the invention has the advantages that by utilizing the closed structure of the powerful magnet A and the powerful magnet B, the closed refrigerator door can not generate cold-air outflow; and when being opened, the refrigerator door is opened easily by utilizing the principle that the opening and closing of the powerful magnet A and the powerful magnet B are carried out by rotary screwing.
