Abstract
The invention discloses a hydraulic spring lock, which comprises a lock body, a lock cylinder and a plectrum and is provided with a hydraulic spring device. The working principle of the hydraulic spring lock is as follows: a hydraulic spring is arranged on the lock body, is sealed and movably fit in a hydraulic cavity of the lock body, is popped out under the action of hydraulic oil and enters into the common spring hole of the lock cylinder, so that the lock cylinder can nor rotate and the lock can not be unlocked; when unlocking the lock, a key is inserted into the lock cylinder to press the common spring back to the common spring hole, the common spring overcomes the hydraulic pressure of the hydraulic spring to press the hydraulic spring back into the guide hole of the lock body, the lock cylinder can rotate, and the plectrum of the lock cylinder unlocks the lock. The hydraulic spring lock is not provided with a spring, thus overcoming the defect that the lock is easy to rust when using a spring outdoors; the elasticity of the hydraulic spring is softer than a spring, thus improving the quality of the spring lock.
