| description | The invention relates to the technical field of gas springs, in particular to a gas spring with a triple protection function, which comprises a cylinder barrel, a plunger rod, a limiting sleeve, a cylinder barrel base and an inflation valve, an overspeed protection structure is arranged at the bottom of the plunger rod, and an overpressure protection structure and an overtravel protection structure are respectively arranged on two sides of the cylinder barrel base. When the nitrogen spring rebounds abnormally and rapidly, the overspeed protection structure at the bottom of the plunger rod works, when the internal pressure of the nitrogen spring rises due to the fact that the temperature in the nitrogen spring is too high or sundries enter the nitrogen spring, the overpressure protection structure starts to work, and when the nitrogen spring exceeds the maximum allowable use stroke in use, the overpressure protection structure stops working. The plunger rod is overpressed to enable the overtravel protection st |
