The present invention relates to a gas spring assembly structure for a counter balance. The gas spring assembly structure for a counter balance comprises: first and second rotary joints (10, 20) connected to links (Not drawn) arranged in both sides and performing a relatively rotational motion; a gas spring (30) arranged between the first and second rotary joints (10, 20), and having a cylinder (31) connected to the first joint (10) and a rod (32) connected to the second joint (20); and an auxiliary connector (40) for assisting the connection between the gas spring (30) and the first and second rotary joints (10, 20). Thus, the present invention can rapidly correspond to an assembly work because it does not need to have a gas charging and discharging device required when the gas spring and the first and second rotary joints are assembled and disassembled. Also, the present invention can protect the gas spring by charging the gas spring with a constant pre-pressure in the assembly work; thereby preventing damage to the gas spring and extending the service life of the gas spring. Also, the present invention can make the maintenance and repair of gas good by preventing the work for unnecessarily discharging and charging the gas in the disassembly work. |
