Description

Technical Field

[0001] The utility model relates to the technical field of gas spring production equipment, in particular to a gas spring multi-station inflation device. Background Art

[0002] A gas spring is a device that uses compressed gas to generate elastic force and is mainly used in industrial machinery, automobiles, aviation and other fields. It mainly consists of a piston rod, a piston, a sealing guide sleeve, a filler, a pressure cylinder and a joint. The pressure cylinder is a closed cavity filled with an inert gas or an oil-gas mixture. The pressure inside the cavity is several times or even dozens of times higher than atmospheric pressure. Gas springs have different structures and types. They have the advantages of adjustable size, high reliability, light weight and long service life, and are widely used. When used for a long time, the inflation pressure of the gas spring needs to be checked regularly to ensure that it is within the standard pressure range.

[0003] Patent publication number "CN217761854U" discloses a "multi-station inflation device for gas springs". The design includes a frame; a loading mechanism, which is arranged on the frame and has a loading box, a pushing block located at the bottom of the loading box, and a first cylinder that drives the pushing block to move. The loading box is used to carry a horizontally placed gas spring, and an opening is provided at the bottom of the loading box to accommodate the passage of the gas spring. The top of the pushing block is sequentially provided with a plurality of grooves for accommodating gas springs, and the grooves are used to receive gas springs from the loading box; an inflation mechanism, which is located on one side of the feeding mechanism and has an inflation head, a pressing block, and a second cylinder that drives the pressing block close to or away from the inflation head. The inflation head is provided with a plurality of inflation ports, and the pressing block is provided with a plurality of pressing rods opposite to the inflation ports, and the pressing rods press the pushed-out gas spring toward the inflation port. This device realizes automatic inflation of the gas spring, but lacks the free disassembly and regulation of the inflation device. The rubber ring of the inflation component is prone to aging after long-term use and needs to be replaced. In addition, when inflating the gas spring, the inflation pressure must be accurately controlled. If the inflation is too high or too low, the performance of the gas spring will be reduced and even the gas spring will be damaged.

[0004] To this end, the utility model provides a gas spring multi-position inflation device to solve the above problems. Utility Model Content
