Description
技术领域technical field
本实用新型涉及气弹簧设备技术领域，尤其是涉及一种多功能气弹簧。The utility model relates to the technical field of gas spring equipment, in particular to a multifunctional gas spring.
背景技术Background technique
气弹簧主要由缸筒、缸筒内的活塞、活塞杆以及阀杆等组成，缸筒内贮有气体或贮有油气混合物。由于活塞占居了缸筒内的容积，故而利用活塞杆的横截面积小于活塞的横截面积从而产生的压力差来实现活塞杆的运动。现有气弹簧行程固定，同时其活塞杆的伸出速度也固定不变，就限制了气弹簧的使用场合，降低了气弹簧的使用效率。The gas spring is mainly composed of a cylinder, a piston in the cylinder, a piston rod and a valve stem, etc., and gas or an oil-gas mixture is stored in the cylinder. Since the piston occupies the volume in the cylinder, the movement of the piston rod is realized by using the pressure difference generated by the cross-sectional area of the piston rod being smaller than that of the piston. The stroke of the existing gas spring is fixed, and the stretching speed of the piston rod is also fixed simultaneously, which limits the use occasions of the gas spring and reduces the use efficiency of the gas spring.

上述多功能气弹簧在运用时，根据需要选择气弹簧的伸出速度，由于作用在无杆腔的压力和作用在有杆腔内的压力相同，而无杆腔和有杆腔的面积不同，根据公式可以得到面积大，则作用力大气弹簧的伸出速度就慢，反之气弹簧的伸出速度就快，而第一活塞杆3和第二活塞杆5的横截面面积部不同，所以第一活塞杆3和第二活塞杆5的伸出速度就不同，根据需要选择气弹簧的伸出速度，同时根据需要选择伸出长度，第一活塞杆3和第二活塞杆5同时伸出时，其行程最大，而在不需要最大行程时，可以选择第一活塞杆3通过第一定位套7固定在缸筒1上，使得第二活塞杆5伸出缸体，或者也可以选择第二活塞杆5通过第二定位套9固定在缸筒1上，使得第一活塞杆3伸出缸体，多重搭配选择，方便使用者使用。When the above-mentioned multifunctional gas spring is in use, the stretching speed of the gas spring should be selected according to the needs. Since the pressure acting on the rodless cavity is the same as the pressure acting on the rod cavity, and the areas of the rodless cavity and the rod cavity are different, According to the formula, it can be obtained that the larger the area, the slower the stretching speed of the active air spring, and the faster the stretching speed of the gas spring, and the cross-sectional areas of the first piston rod 3 and the second piston rod 5 are not the same, so the first piston rod 3 and the second piston rod 5 have different cross-sectional areas, so the second The extension speeds of the first piston rod 3 and the second piston rod 5 are different. The extension speed of the gas spring is selected according to the needs, and the extension length is selected according to the needs. When the first piston rod 3 and the second piston rod 5 are extended at the same time , its stroke is the largest, and when the maximum stroke is not required, the first piston rod 3 can be selected to be fixed on the cylinder barrel 1 through the first positioning sleeve 7, so that the second piston rod 5 extends out of the cylinder body, or the second piston rod can be selected. The piston rod 5 is fixed on the cylinder barrel 1 through the second positioning sleeve 9, so that the first piston rod 3 extends out of the cylinder body, and multiple collocation options are convenient for users to use.
