Technical Field

[0001] The utility model belongs to the technical field of protective devices and relates to a protective device for a carbon dioxide laser tube. Background Art

[0002] A CO2 laser tube is a gas laser that uses CO2 gas as the working substance. The discharge tube is usually made of glass or quartz material and is filled with CO2 gas and other auxiliary gases.

The protective device is configured to place the carbon dioxide laser tube on one side of a mounting device, and then rotate a fixing device so that the fixing device and the mounting device limit and fix the carbon dioxide laser tube. The fixing device and the mounting device are then connected and fixed by tightening screws. A fluff protection gasket 1 is installed on one side of the inner wall of the mounting device, and a fluff protection gasket 2 is installed on one side of the inner wall of the fixing device.

One side of the slider 14 is fixedly connected with a slide rod 15, and the other end of the slide rod 15 slides through the fixed block 17.

[0050] A positioning rod 26 is fixedly connected to one side of a rectangular block 20 away from the pull ring 22 , a positioning cylinder 25 is fixedly connected to the inner wall of the housing 1 , and the positioning rod 26 is slidably connected to the inside of the positioning cylinder 25 .

[0051] Working principle:

[0052] When in use, the box cover 2 is opened, the carbon dioxide laser tube 5 is placed on a plurality of fixed half rings 8 , and the left end of the carbon dioxide laser tube 5 is connected to the laser emitting seat 4 .

[0053] The rotating half ring 9 is rotated from right to left in sequence to rotate toward the top of the CO2 laser tube 5. The rotating half ring 9 drives the second fixed cylinder 24 to rotate, so that the connecting shaft rotates in the first fixed cylinder 23 and twists the torsion spring 11, so that the torsion spring 11 generates torque.

[0054] The rotating half ring 9 drives the block 12 to rotate, so that the bottom end of the block 12 passes through the through hole of the fixed half ring 8. The inclined surface end at the bottom of the block 12 presses the inclined surface of the card plate 13, so that the card plate 13 slides to the side away from the block 12, thereby pushing the slider 14 and the connecting plate 18 to slide to the side close to the fixed block 17, and compressing the first spring 16, so that the slide bar 15 slides through the fixed block 17.

[0055] When the inclined surface end at the bottom of the block 12 slides to the bottom of the card plate 13, the inclined surface end of the block 12 no longer presses the card plate 13, and the first spring 16 pushes the slider 14 to slide the card plate 13 to the top of the inclined surface end at the bottom of the block 12, and the slider 14 slides to the side of the inclined surface end at the bottom of the block 12 to fix the block 12. Then, the rotating half ring 9 is fixed on the top of the CO2 laser tube 5, and the purpose of protecting the CO2 laser tube 5 is achieved by the cooperation of the fixed half ring 8 and the rotating half ring 9.

[0056] When the block 12 moves downward, it pushes the card plate 13, so that when the connecting plate 18 slides toward the side close to the fixed block 17, the connecting plate 18 drives the pull rope 19 to move together. The pull rope 19 has a small elasticity, so when one of the connecting plates 18 slides, the pull rope 19 located between the two connecting plates 18 will be slightly deformed, and will not affect the fixing effect of the remaining connecting plates 18 on the block 12.

[0057] Then, the CO2 laser tube 5 can be fixed by rotating the half ring 9 in turn. After fixing, the box cover 2 is fixed to the top of the housing 1 to seal the CO2 laser tube 5 in the housing 1. When in use, the heat dissipation plate 3 can be used for ventilation and heat dissipation.

[0058] When the CO2 laser tube 5 needs to be removed, the box cover 2 is first opened. The pull ring 22 is pulled to the right of the housing 1 to drive the pull rope 19 to slide, so that the two rectangular blocks 20 slide to the right in the housing 1, and the rectangular block 20 at the right end will compress the second spring 21. The rectangular block 20 at the left end will stretch the second spring 21, and the positioning rod 26 will slide in the positioning cylinder 25 at the same time.

[0059] Since the pull rope 19 will be slightly deformed, after the deformation, the pull rope 19 will drive the multiple connecting plates 18 to slide toward the side close to the fixed block 17, so that the slider 14 slides toward the side of the fixed block 17, and the slide bar 15 slides inside the fixed block 17 and compresses the first spring 16. The clamping plate 13 leaves the top of the bottom inclined surface end of the clamping block 12, and the slider 14 leaves one side of the bottom inclined surface end of the clamping block 12.

[0060] The clamping plate 13 no longer restricts the clamping block 12 , and the rotating half ring 9 rotates toward the outside of the fixed half ring 8 under the action of the torsion spring 11 , so that the rotating half ring 9 automatically leaves the carbon dioxide laser tube 5 .

[0061] The pull ring 22 is released, and under the action of the two second springs 21 , the pull rope 19 is pulled to slide to the left, and at the same time, one end of the positioning rod 26 slides into the positioning tube 25 .

[0062] When the pull rope 19 moves, it drives the connecting plate 18 to slide. At the same time, under the action of the elastic force of the first spring 16, the slider 14 and the clamping plate 13 slide to the side away from the fixed block 17 until they return to the initial state. At this time, the carbon dioxide laser tube 5 can be taken out.

[0063] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
