Problems solved by technology

[0006] It can be seen from the above comparative documents that people usually do not use tension springs or torsion springs to close the door in the prior art, but simply use mechanical force to realize the opening and closing of the door body. However, what the present invention relates to is a large-scale The refrigerator has a large door body, and it is difficult for people to switch the door body by pure mechanical force when using it. After continuous experimental research, the technicians of the present invention finally developed an automatic door closing system suitable for large freezer doors.

Abstract

The automatic shut-off structure for large refrigerator door to be set in the upper and / or lower part of the door includes one connector and one hinge axis connected to the connector. The connector has one rectangular first support wall with one central through hole and one second support wall; and the hinge axis has one end passing through the central through hole and the other end socketed with one upper hinge and one spring before fixed through one spring end plug. The present invention has one cam with inclined surface and one spring set to one end of the cam, and when two slanted bosses move relatively, the cam will extrude the spring and the door with great weight is pulled back by the deformed spring to close.

Description

technical field [0001] The invention relates to an automatic closing structure for a door, in particular to an automatic closing structure for a glass door used in a freezer, which belongs to the spare parts of the door body. Background technique [0002] The door body of refrigeration appliances such as refrigerators or freezers will forget to close the door or the door body will not be closed properly due to the negligence of the user when using it, which will cause the cold air in the refrigerator or freezer to leak out, which will increase the power consumption of the whole machine and make it worse. Seriously, it will also cause the food in the box to deteriorate and go bad. Its door body of existing upright freezer generally needs to be closed by manpower, and such operation is strenuous, and sometimes door body also can close not tight, makes cooling capacity loss, has influenced freezing or refrigeration effect. Some vertical freezers use tension springs or torsion ...
