[0002] The design concept behind the push-type hood lock is to increase the safety of the car and prevent the hood from accidentally opening while driving. This locking device is designed to ensure that the hood is tightly closed to prevent it from accidentally opening due to vibration or other factors while driving. In the automotive industry, the safety of the hood is crucial because an unsecured hood may cause serious danger to the driver and other road users. Therefore, the hood locking device is one of the integral parts of vehicle design.

[0003] However, most of the existing hoods need to enter the cab and then use a corresponding wrench to open the hood. Therefore, in order to improve the safety and convenience of the car, relevant personnel can open the hood without entering the cab, and protect the safety of the driver and other road users, a push-type hood lock that is convenient for fixing and sealing the hood is proposed.
