[0002] With the rapid development of people's living needs and technological progress, the demand for carbon dioxide shielded welding machines is increasing. Carbon dioxide shielded welding machine is short for carbon dioxide shielded welding machine. The input voltage of low-power carbon dioxide shielded welding machine is generally 220V AC, and high-power uses 380V AC power supply. The output voltage is generally 12-36V. It is mainly used for low-carbon steel, low-alloy high-strength steel, with high welding productivity, and can be used for welding thin plates and medium-thick plates.

[0003] When the existing two-protection welding machines are in use, the knobs for adjusting the voltage and current on the surface mostly lack a protective structure. It is easy to touch the knobs by mistake during the two-protection welding process, resulting in inaccurate voltage and current. Inappropriate voltage and current will also affect the welding effect. In addition, when the existing welding machines are not in use, most of the cables connecting the circuits are disassembled, and the unused joints are directly exposed to the outside, which makes it easy for foreign matter such as water to come into contact with the joints, which not only affects the use but also easily leads to safety hazards.

Both sides of the surface of the two-protection welding machine body 1 are fixedly connected with a connecting frame 2, and one side of the connecting frame 2 is provided with a mounting groove 3, and the inner wall of the mounting groove 3 is slidably connected with a sliding block 5, and the surface of the sliding block 5 is fixedly connected with an upper blocking plate 6, and the upper blocking plate 6 can block the upper part of the surface of the two-protection welding machine body 1, so as to block the buttons and the display screen on the surface of the two-protection welding machine body 1, so as to prevent the two-protection welding machine from accidentally touching the buttons and the display screen when in use and affecting the welding, and a positioning groove 4 is provided on one side of the inner cavity of the mounting groove 3, and the surface of the sliding block 5 is slidably connected with the inner wall of the positioning groove 4, under this action, the upper blocking plate 6, it limits itself under the cooperation of weight, so that it will not move easily. The sliding block 5 is designed as a cylinder. The surface of the sliding block 5 is slidably connected with the inner wall of the positioning groove 4 and the mounting groove 3. The shape of the sliding block 5 can make it move inside the mounting groove 3 and the positioning groove 4 without being affected, so that when the staff adjusts the numerical value through the button and the display screen, the upper blocking plate 6 can slide inside the mounting groove 3 through the sliding block 5, so that the sliding block 5 can move to the top of the second protection welding machine body 1, and no longer block the button and the display screen, so as to avoid the upper blocking plate 6 always blocking the button and the display screen and affecting the normal use of the second protection welding machine body 1. The other side of the inner cavity of the mounting groove 3 is fixedly connected with a magnet 13. The material of the sliding block 5 is iron, and the magnetic The iron 13 is used in conjunction with the sliding block 5, under which the sliding block 5 can be limited, so that the upper blocking plate 6 will not move easily when the staff adjusts the parameters. Two places on one side of the upper blocking plate 6 are fixedly connected with tension springs 7, and the other end of the tension spring 7 is fixedly connected with a lower blocking plate 8. Under the action of the lower blocking plate 8, the joints on the surface of the two-protection welding machine body 1 can be blocked to prevent foreign matter and water from entering the inside of the joints when the two-protection welding machine body 1 is not in use and affecting the normal use of the two-protection welding machine body 1. In addition, with the cooperation of the tension spring 7, the staff can fit the lower blocking plate 8 with the upper blocking plate 6 when it does not move, and the joints will not be blocked, so as to prevent the lower blocking plate 8 from affecting the normal wiring of the two-protection welding machine body 1 when in use. One side of the blocking plate 8 is slidably connected to one side of the upper blocking plate 6, under which the lower blocking plate 8 can be more stable when moving. Two places on one side of the upper blocking plate 6 are provided with connecting grooves 11, and two places on one side of the lower blocking plate 8 are fixedly connected with connecting blocks 12. The surface of the connecting block 12 is slidably connected to the inner wall of the connecting groove 11, under which the lower blocking plate 8 can be guided when it moves, so that it can be more stable when moving. The cross-sectional shapes of the connecting groove 11 and the connecting block 12 are both T-shaped designs, under which the connecting block 12 cannot be separated from the inside of the connecting groove 11, thereby improving the stability of the lower blocking plate 8 when in use. An auxiliary mechanism 9 is provided on one side of the connecting frame 2, and the auxiliary mechanism 9 can assist the lower blocking plate 8 in moving.Thereby, the auxiliary mechanism 9 is more stable when moving, and the lower blocking plate 8 can be limited to reduce its range of motion, thereby improving the protection effect of the joint. A positioning mechanism 10 is provided on one side of the lower blocking plate 8, and the positioning mechanism 10 can fix the lower blocking plate 8, so that the lower blocking plate 8 can always block the joint when the two-protection welding machine body 1 is not in use, thereby improving the use effect of the two-protection welding machine body 1.

[0022] The auxiliary mechanism 9 includes a guide block 91, one side of which is fixedly connected to the surface of the lower blocking plate 8, and a guide groove 92 is provided on one side of the connecting frame 2. The inner wall of the guide groove 92 is slidably connected to the surface of the guide block 91, under this action, the lower blocking plate 8 can be guided when it moves, making it more stable when moving, and the lower blocking plate 8 can also be limited to reduce its range of movement. The inner wall of the guide groove 92 is provided with a movable groove 93, and the inner wall of the movable groove 93 is slidably connected to the surface of the guide block 91. Under this action, when the lower blocking plate 8 needs to be adjusted, the guide block 91 can be separated from the inside of the guide groove 92 to avoid the guide block 91 being unable to separate from the inside of the guide groove 92 and affecting the adjustment of the upper blocking plate 6. The movable groove 93 is an arc-shaped design, and the center of the movable groove 93 is at the same center as the center of the sliding block 5. Under this action, the guide block 91 can be smoother when moving.

[0023] The positioning mechanism 10 includes a connecting rod 101, one end of which is rotatably connected to the surface of the lower blocking plate 8, a positioning frame 102 is fixedly connected to the surface of the connecting rod 101, and a clamping frame 103 is fixedly connected to the surface of the second welding machine body 1. The positioning frame 102 and the clamping frame 103 are both L-shaped structures. The positioning frame 102 and the clamping frame 103 are used in conjunction with each other. Under this action, the connecting rod 101 can be rotated to make the positioning frame 102 and the clamping frame 103 clamped with each other, so as to limit the lower blocking plate 8.
