| description | The utility model relates to a speed locker with an automatic unlocking function, which solves the problem that the maintenance cost after an earthquake is greatly increased due to the fact that the speed locker in the prior art needs to be replaced after the earthquake each time. End covers are arranged at the two ends of the cylinder body, a pressure relief end cover is arranged between the end covers, a closed locking cavity is defined by the pressure relief end cover and the cylinder body, a pressure relief valve and a one-way valve are arranged on the pressure relief end cover, the locking cavity is filled with flowing media, and a piston extends into the locking cavity through a piston rod to reciprocate along the axis of the piston. The pressure relief end cover and the cylinder body form a closed pressure relief cavity, and the multiple pressure relief valves and the multiple one-way valves are sequentially distributed on the pressure relief end cover at equal intervals.
