Technical Field

[0001] The utility model relates to the technical field of welder protection, in particular to a protection mechanism for a CO2 welder. Background Technique

[0002] A CO2 welder is used in welding. The CO2 welder is a short name, and its full name is a carbon dioxide shielded welding machine. The CO2 welder has the characteristics of simple operation, easy arc ignition and stable arc. At the same time, it has a large adjustment range of voltage and current, and the penetration depth and weld seam are easy to control. The existing CO2 welder does not have a protection function. Since most CO2 welders work in a harsh environment, they are very likely to be accidentally hit by high-altitude objects. Due to the very large weight of the vertically descending object, it will affect the CO2 welder, and in severe cases, it will cause damage to the CO2 welder.

[0003] According to a protection mechanism for a welding machine disclosed in the Chinese patent document with the publication number CN210755776U, by setting the cooperation of a welding machine body, a groove, a positioning box, a first spring, a bracket, a pulley, a top cover, a limiting groove, a second spring, a through hole and a handle, the problem that the existing welding machine does not have a protection function is solved.

[0004] However, the above device can only protect the upper end of the welder and cannot protect the control panel of the welder. During the process of electric welding, there will be many sputtered sparks, and these sparks falling on the control panel of the welder are likely to cause damage to the control panel of the welder. For this reason, a protection mechanism for a CO2 welder is proposed. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The present invention provides a technical solution: As Figures 1 to 5 shown, in this embodiment, a protection mechanism for a CO2 welder includes a welder body 1. A protective top plate 2 is arranged above the welder body 1. The protective top plate 2 is movably connected to the welder body 1 through a buffer mechanism. A heat dissipation window 15 is arranged at the rear end of the welder body 1. A control panel 3 is arranged at the front end of the welder body 1. A protective front plate 4 is arranged at the front end of the control panel 3. A movable plate 13 is fixedly installed at the upper end of the protective front plate 4. Frame 11s are respectively arranged on both sides of the control panel 3. Both frame 11s are fixedly connected to the welder body 1. Movable grooves 12 are respectively opened at one ends of the two frame 11s close to each other. Both ends of the movable plate 13 are respectively slidably connected in the two movable grooves 12.

[0023] Among them, the buffer mechanism is composed of four buffer components. The four buffer components are symmetrically distributed in pairs on both sides of the welder body 1. The buffer component is composed of a fixing piece 6, a spring 8, a slide block 9 and a connecting rod 10. The fixing piece 6 is fixedly connected to the outer wall of the welder body 1. The fixing piece 6 is arranged vertically. A chute 7 is opened inside the fixing piece 6. A slide block 9 is slidably installed in the chute 7. A spring 8 is fixedly connected between the bottom of the slide block 9 and the bottom of the inner cavity of the chute 7. A connecting rod 10 is fixedly installed at the upper end of the slide block 9. The upper end of the connecting rod 10 slidably penetrates through the fixing piece 6 and is fixedly connected to the bottom of the protective top plate 2.

[0024] When an object falls from above the welder body 1, it will land on the protective top plate 2. The spring 8 connected to the bottom of the slide block 9 can buffer the impact received by the protective top plate 2, thereby avoiding damage to the welder body 1.

[0025] Among them, the movable plate 13 has elastic properties, and the thickness of the movable plate 13 is greater than the thickness of the movable groove 12.

[0026] With such a setting, after the movable plate 13 is embedded in the movable slot 12, since the thickness of the movable plate 13 is greater than that of the movable slot 12, the movable plate 13 will be squeezed and deformed, and the expansion force generated when the movable plate 13 restores its deformation will fix the movable plate 13 in the movable slot 12, ensuring that the movable plate 13 will not slide in the movable slot 12 without external force, thus preventing the front protection plate 4 from moving randomly without external force.

[0027] Among them, four universal wheels 5 are provided at the bottom of the welding machine body 1, and the four universal wheels 5 are distributed at the four corner positions of the bottom of the welding machine body 1.

[0028] The provided universal wheels 5 facilitate the handling and movement of the welding machine body 1.

[0029] Among them, a handle 14 is fixedly connected to the bottom of the front protection plate 4.

[0030] The provided handle 14 facilitates the movement of the front protection plate 4.

[0031] The present utility model provides a protection mechanism for a CO2 welding machine, and the specific working principle is as follows:

[0032] When an object falls from above the welding machine body 1, it will land on the top protection plate 2. The spring 8 connected to the bottom of the slider 9 can buffer the impact received by the top protection plate 2, thus preventing the welding machine body 1 from being damaged. When welding, move the front protection plate 4 upward to cover the control panel 3, preventing the sputtered sparks from falling on the control panel 3 during welding and causing damage to the control panel 3. When using the control panel 3, just move the front protection plate 4 downward. Since the movable plate 13 has elastic properties and the thickness of the movable plate 13 is greater than that of the movable slot 12, the movable plate 13 will be squeezed and deformed in the movable slot 12, and the expansion force generated when the movable plate 13 restores its deformation will fix the movable plate 13 in the movable slot 12, ensuring that the movable plate 13 will not slide in the movable slot 12 without external force, thus preventing the front protection plate 4 from shaking without external force. The provided universal wheels 5 facilitate the handling and movement of the welding machine body 1.

[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
