Abstract

The invention discloses a gas spring. The gas spring comprises a cylinder body of a sealing structure. The cylinder body is internally provided with a cavity and a piston rod slidably connected into the cavity, a boss is fixedly connected to the lower end of the piston rod, and the area of the upper end of the boss is smaller than that of the lower end of the boss. Gas guiding grooves are formed in the cylinder body in the axial direction of the cylinder body and comprise the first gas guiding groove and at least one second gas guiding groove. The first gas guiding groove is formed in the end,away from the piston rod, of the cylinder body, the length of the first gas guiding groove and the length of each second gas guiding groove are both greater than the thickness of the boss, and the two ends of the first gas guiding groove and the two ends of each second gas guiding groove communicate with the cavity. According to the gas spring, multiple gas guiding grooves can be formed in the gas spring according to the needs, gas springs with multiple strokes can be provided, thus multiple supporting balance points can be provided, different working requirements are met, and the applicability of the gas spring is improved.

Description

technical field [0001] The invention relates to the technical field of gas springs, in particular to a gas spring and a cab side door using the gas spring. Background technique [0002] The application of gas springs on forklifts is very common. They are used on the hood, box cover, and side doors. Traditional gas springs only have one stroke. When it is necessary to realize the secondary opening angle of the side door, some mechanical structures are often added, which makes the installation complicated. , which not only increases the cost, but also is not very convenient to operate. [0003] Due to the very compact structure of the electric forklift, some parts and components such as batteries and motors are mostly arranged under the interior of the cab. In order to facilitate maintenance and battery hoisting and replacement, the opening angle of the cab side door is required to be greater than 90°. After the side door is opened, it will rebound due to gravity or external...
