Abstract
The utility model discloses a carbon dioxide laser tube. The carbon dioxide laser tube comprises a tube body which is made of quartz glass and has two open ends. The two ends of the tube body are both provided with cooling sleeves made of ceramic. The laser tube is characterized in that the side wall of a mounting chamber is provided with multiple annular grooves which are arranged in a coaxial manner, and annular rubber loops are arranged inside the annular grooves. When the carbon dioxide laser tube is switched between a use state and a non-use state, the cooling sleeves and the tube body can expand with heat and contract with cold, and such deformation may cause squeezing on colloid or separation from the colloid. At the moment, the multiple annular rubber loops arranged inside the annular grooves can have a good buffer effect on the deformation. When the cooling sleeves and the tube body are heated, the annular rubber loops are squeezed and contracted; and when the cooling sleeves and the tube body are cooled, the annular rubber loops restore to the original shapes. The annular rubber loops can always be adhered on the colloid and the cooling sleeves so that cracks between the colloid and the cooling sleeves and tube body can be prevented effectively.
