Description

Air spring Technical Field The application relates to the technical field of gas springs, in particular to a gas spring. Background The gas spring is an industrial fitting with functions of supporting, buffering, braking, height regulating and angle regulating, and is composed of pressure cylinder, piston rod, piston, sealing guide sleeve, filler (inert gas or oil-gas mixture), in-cylinder control element, out-cylinder control element (controllable gas spring) and joint. The existing gas spring travel distance is mainly determined by the length of a gas spring pressure cylinder, the gas spring is installed and used, when the travel of the gas spring needs to be changed, the two ends of the gas spring need to be disassembled, the gas spring is possibly positioned inside the equipment, so that the disassembly efficiency of the gas spring is low, and the adaptability of the gas spring is poor. Disclosure of utility model The utility model aims to overcome the defects and shortcomings of the prior art and provides a gas spring. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The sealing guide sleeve is sleeved and fixed at the opening end of the shell, the piston slides in the shell, one end of the moving rod is inserted and fixed in the piston, the other end of the moving rod is inserted and slides in the side wall of the sealing guide sleeve, a driving rod is inserted and slides in the side wall of the sealing guide sleeve, an adjusting block slides in the shell, the adjusting block is located on one side, close to the sealing guide sleeve, of the piston, and one end of the driving rod is arranged on one side of the adjusting block. Preferably, the driving rod is provided with a balancing stand at one end close to the piston, and the balancing stand is mounted on the side wall of the adjusting block. Preferably, the driving rod is composed of a plurality of rotating rods, the rotating rods are arranged in an arrangement mode, and two adjacent rotating rods are connected in a rotating mode. Preferably, a storage bag is arranged on the outer side wall of the shell, and the storage bag can be used for storing the rotating rod. Preferably, a connecting plate is arranged between two adjacent rotating rods, connecting rods are respectively arranged on the same sides of two ends of the connecting plate, the two connecting rods are respectively inserted into the side walls of the two adjacent rotating rods, inserting blocks are respectively arranged at two ends of the connecting plate, and inserting grooves for the inserting blocks to be inserted and fixed are formed in the side walls of the rotating rods. Preferably, the connecting rod is provided with a limiting block at one end far away from the connecting plate, and when the limiting block is mutually attached to the side wall of the rotating rod, the plug-in block is separated from the plug-in groove. Preferably, the outer end of the sealing guide sleeve is provided with a locking piece, the locking piece comprises a locking plate and a stirring bar, the stirring bar moves back and forth in the outer end of the sealing guide sleeve, the locking plate is arranged at one end of the stirring bar, and one end of the locking plate can be inserted between two adjacent rotating rods. In summary, the present application includes at least one of the following beneficial technical effects: 1. When the stroke of the gas spring is required to be regulated, connecting rods at two ends of the connecting plate are respectively inserted into the side walls at one ends of the two adjacent rotating rods, then the inserting blocks are inserted and fixed in the inserting grooves, so that the rotating rods are arranged in the same straight line, then the driving rods are pushed to drive the regulating blocks to slide in the shell, the distance between the regulating blocks and the sealing guide sleeve is changed, then the stirring strips are stirred to insert one end of the locking plate between the two adjacent rotating rods, so that the driving rods are locked and fixed, then when the piston moves in the shell, the moving distance of the piston can be changed under the limitation of the regulating blocks, and then the stroke distance of the gas spring is changed, so that the external requirement is met, the gas spring is not required to be disassembled, and the adaptability of the gas spring is improved; 2. After the drive rod pushes the piston, when the outer end of the drive rod is located outside the sealing guide sleeve, the connecting plate located outside the sealing guide sleeve moves, so that the plug block is separated from the plug groove, two adjacent rotating rods rotate, and then the outer end of the drive rod is placed in the storage bag, and the outer end of the drive rod can be prevented from affecting the gas spring.
