Technical Field

[0001] The present application relates to the technical field of argon arc welding, and in particular to an adjustable eye protection device for an argon arc welding machine. Background Art

[0002] Argon arc welding machine is a machine that uses argon arc welding, which uses high voltage breakdown to start the arc. Argon arc welding is tungsten inert gas shielded arc welding, which refers to a welding method that uses industrial tungsten or active tungsten as an infusible electrode and inert gas as protection, referred to as TIG. It is generally used for welding thin plates of 6 to 10 mm and single-sided welding of thick plates and double-sided forming of the bottom welding. Commonly used welding machines include the domestic YC-150 manual tungsten inert gas arc welding.

[0003] When using the argon arc welding machine, the operator needs to wear goggles to protect the eyes. Traditional eye protection devices generally install protective glasses on a mask and then wear them on the head to achieve the purpose of protection. However, due to the presence of filter lenses, workers cannot easily observe the status of the welding workpiece when wearing them. They need to frequently remove the eye protection device, which is cumbersome to operate and reduces the worker's work efficiency in welding the workpiece.

[0004] Therefore, a kind of eye protection device that can conveniently adjust the position of filter lens is needed. Utility Model Content

[0005] In order to conveniently adjust the position of the filter lens during welding operations.

[0007] Optionally, one end of the inner wall of the telescopic outer tube is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to one end of the telescopic inner rod.

[0008] Optionally, the outer surface of the top of the push plate is inclined, and the inclined surfaces at both ends of the top of the push plate are symmetrically arranged.

[0009] Optionally, the inner wall in the middle of the limit block is slidably connected to the outer surface in the middle of the limit rod, and one end of the limit rod is fixedly connected to one side of the protective mask.

[0010] Optionally, grooves are formed at both ends of one side of the limit plate, and the inner walls of the grooves at both ends of one side of the limit plate are slidably connected to the outer surface of one side of the limit bar, and the top and bottom outer surfaces of the limit plate are slidably connected to the bottom and top outer surfaces of the limit bar respectively.

[0011] Optionally, the outer surface of one side of the limiting slide plate is slidably connected to the inner wall of the middle part of the limiting slide groove, and the other side of the limiting slide groove is fixedly connected to one side of the protective mask.

[0015] 2. The utility model, through the cooperation between the pressing rod and the limit plate, adjusts the position of the groove on one side of the limit plate under the limit bar, and can control whether the groove on one side of the limit plate can slide on the outer surface of one side of the limit bar. The position of the limit plate can be controlled to prevent the filter lens from moving randomly during welding work, causing the workers' eyes to be damaged by the welding arc.

[0024] The following is combined with Figure 1-6 This application is described in further detail.

[0025] The present application discloses an adjustable eye protection device for a argon arc welding machine. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, it includes a protective mask 1, one side of the protective mask 1 is fixedly connected to one end of the telescopic outer tube 2 through a fixing plate, the inner wall of the other end of the telescopic outer tube 2 is slidably connected to the outer surface of one end of the telescopic inner rod 3, the other end of the telescopic inner rod 3 is rotatably connected to the middle inner wall of the pulley 4 through a connecting frame, the middle outer surface of the pulley 4 is slidably connected to the top outer surface of the push plate 5, the bottom of the push plate 5 is fixedly connected to the top of the limit block 6, the bottom of the limit block 6 is fixedly connected to one end of the slide rod 7 through a fixing frame, the middle outer surface of the slide rod 7 is slidably connected to the middle inner wall of the limit plate 8, and one end of the limit plate 8 The fixing frame is fixedly connected to one end of the pressing rod 9, the middle outer surface of the pressing rod 9 is slidably connected to the middle inner wall of the limiting slide 10, and one side of the limiting slide 10 is fixedly connected to one end of the filter lens 11. The pressing rod 9 drives the outer surface of one side of the limiting slide 10 to slide in the middle inner wall of the limiting slide groove 12, so that the limiting slide 10 drives the filter lens 11 to move up and down, and the position of the filter lens 11 is adjusted, so that the position of the filter lens 11 can be conveniently adjusted, and the filter lens 11 can be removed from the eyes of the workers without removing the eye protection device.

[0026] See also Figure 4 One end of the inner wall of the telescopic outer tube 2 is fixedly connected to one end of the spring 16, and the other end of the spring 16 is fixedly connected to one end of the telescopic inner rod 3. Through the setting of the spring 16, the telescopic inner rod 3 can be pushed downward in time to drive the push plate 5 to reset.

[0027] See also Figure 6The outer surface of the top of the pushing plate 5 is inclined, and the inclined surfaces at both ends of the top of the pushing plate 5 are symmetrically arranged. By the inclined arrangement of the outer surface of the top of the pushing plate 5, the pulley 4 can drive the telescopic inner rod 3 to move up and down when the pushing plate 5 moves laterally, changing the state of the spring 16. The symmetrical arrangement of the inclined surfaces at both ends of the top of the pushing plate 5 can enable the pushing plate 5 to drive the telescopic inner rod 3 to move upward when it starts to move laterally, no matter in which direction the pushing plate 5 moves laterally.

[0028] See also Figure 2 The inner wall in the middle of the limit block 6 is slidably connected to the outer surface in the middle of the limit rod 15, and one end of the limit rod 15 is fixedly connected to one side of the protective mask 1. The inner wall in the middle of the limit block 6 slides on the outer surface in the middle of the limit rod 15, and the movement trajectory of the push plate 5 can be fixed by the limit block 6, thereby improving the stability of the push plate 5 when moving.

[0029] See also Figure 5 Both ends of one side of the limit plate 8 are provided with grooves, and the inner walls of the grooves at both ends of one side of the limit plate 8 are slidably connected to the outer surface of one side of the limit bar 14, and the top and bottom outer surfaces of the limit plate 8 are slidably connected to the bottom and top outer surfaces of the limit bar 14 respectively. By setting the grooves at both ends of one side of the limit plate 8, when the limit plate 8 starts to move horizontally, no matter in which direction it moves, the grooves on one side of the limit plate 8 can move under the limit bar 14 and align with it, so that the limit plate 8 will not be blocked by the limit bar 14 and can move up and down smoothly.

[0030] See also Figure 3 The outer surface of one side of the limiting slide 10 is slidably connected to the inner wall of the middle part of the limiting slide groove 12, and the other side of the limiting slide groove 12 is fixedly connected to one side of the protective mask 1. By sliding the outer surface of one side of the limiting slide 10 in the inner wall of the middle part of the limiting slide groove 12, the moving trajectory of the filter lens 11 can be fixed by the limiting slide 10, thereby improving the stability of the filter lens 11 when moving.

[0031] See also Figure 6 There are two pressing rods 9, one end of the two pressing rods 9 is fixedly connected to the two ends of the limit plate 8 through two fixing frames, the outer surfaces of the other ends of the two pressing rods 9 are slidably connected to the inner walls of the two ends of the protective shell 13, and one side of the protective shell 13 is fixedly connected to one side of the protective mask 1. Through the arrangement of the two pressing rods 9, the worker can easily press the pressing rod 9 to adjust the position of the filter lens 11 regardless of whether he uses his left hand or his right hand.

[0032] The implementation principle of an adjustable eye protection device for an argon arc welding machine in the embodiment of the present application is as follows: by pressing the pressing rod 9, the outer surface of the middle part of the pressing rod 9 slides inside the inner wall of the middle part of the limiting slide plate 10, so that the pressing rod 9 drives the limiting plate 8 to move laterally through the fixing frame, and the position of the groove on one side of the limiting plate 8 is adjusted so that the lower part of the limiting strip 14 is aligned with it when the groove on one side of the limiting plate 8 moves. When the limiting plate 8 moves laterally, the limiting block 6 will be driven to move laterally through the sliding rod 7, so that the inner wall in the middle part of the limiting block 6 slides on the outer surface in the middle part of the limiting rod 15. When the limiting block 6 moves laterally, it will drive the pushing plate 5 to move laterally. The inclined outer surface of the top of the pushing plate 5 will drive the telescopic inner rod 3 to move upward through the pulley 4, so that the telescopic inner rod 3 is inserted into the telescopic outer tube 2, and the spring 16 is squeezed to push the pressing rod 9 to move upward, so that the outer surface of one side of the limiting slide plate 10 is in the limiting slide groove 12 The filter lens 11 is completely removed from the eyes of the worker, and the pressure on the pressing rod 9 is released. The spring 16 releases the thrust, pushing the telescopic inner rod 3 to move downward, so that the pulley 4 drives the pushing plate 5 to move horizontally for resetting, driving the limiting plate 8 to move horizontally, so that the groove of the limiting plate 8 is moved away from the top of the limiting strip 14, and then the limiting strip 14 limits the position of the limiting plate 8, and the worker can conveniently observe the state of the welding workpiece. When welding is needed again, pressing the pressing rod 9 and pulling the pressing rod 9 to move downward can drive the filter lens 11 to move downward, so that the filter lens 11 returns to the eyes of the worker again.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
