Abstract

The invention discloses a safety catch used for an air-conditioning cover plate of train, which comprises the train air-conditioning cover plate and a train air conditioner rack. The invention is characterized in that the safety catch also comprises two parts of a safety buckle component and a safety ring component, the safety buckle component is arranged on the train air-conditioning cover plate, the safety ring component is arranged on the corresponding position of the train air conditioner rack, the safety buckle component can be automatically buckled with the safety ring component when the train air-conditioning plate is closed. The safety buckle component comprises a safety buckle, a connecting rod, a pedestal and a spring. The safety ring component comprises a safety ring, an installation seat and a shaft. The invention has the advantages of simple structure, reliability and easy operation; the cover plate is automatically locked when the cover plate is closed so that the security of the cover plate can be ensured during the train operation; under the condition that the air-conditioning cover plate is unlocked, the safety catch is capable of preventing the air-conditioning cover plate from flying out, so that more effective guarantee for security of train air-conditioning is added during the train operation.

Description

technical field [0001] The invention discloses a safety lock for a train air-conditioning cover plate, and in particular relates to sheet metal structures of air-conditioning systems such as trains, subways, and trains. Background technique [0002] At present, in order to facilitate maintenance, the cover plate structure of the train air conditioning system is basically fixed by hinges and cam locks. Therefore, to lock the cover plate, each rotary cam lock needs to be manually rotated, so there is a certain risk of missed lock. With the development of China's railways and urban rails, the requirements for the safety performance of trains are getting higher and higher, so the necessity of the existence of safety locks has also been paid more and more attention. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a safety lock for the train air-conditioning cover plate, which can automatically lock the cover plate...
