Abstract

The invention relates to the technical field of microwave devices, in particular to a seal ring for a cabinet type microwave device door, the seal ring is a two-layer structure comprising a base layer and a surface layer, the base layer of the seal ring comprises the following components by weight percent: 95%-99% of silicone rubber and 1%-5% of modified auxiliary, the surface layer of the seal ring comprises the following components by weight percent: 30%-34% of silicon rubber, 0.5%-1% of modified auxiliary, 64%-68% of composite magnetic material and 0.1%-0.5% vulcanizing agent. Compared with the prior art, the cabinet type microwave device door can be closed by self-absorption, the switch is free and easy, and the structure is novel and simple, has self-absorption force and can effectively ensure the sealing property of the microwave device door, enhance the safety of the use, lead the use to be very portable and achieve the purpose of easy switching, thereby realizing good sealing property and being firm and durable.

Description

[technical field] [0001] The invention relates to the technical field of microwave equipment, in particular to a sealing ring for a door of a cabinet type microwave equipment. [Background technique] [0002] At present, the structure of the existing cabinet-type microwave equipment door sealing ring is relatively complex and bulky, and most of them adopt hard combination methods such as buckle type or hook type. Leakage is a major safety hazard. [0003] In order to maintain the tightness of the door sealing ring of cabinet microwave equipment for a long time, it is urgent to improve the structure of the device to enhance the safety and convenience of microwave equipment. [Content of the invention] [0004] The object of the present invention is to solve the above-mentioned shortcomings and provide a door seal ring for cabinet microwave equipment, which has a simple structure, is easy to use, self-priming and closes, and has good sealing performance. [0005] In order to...
