[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a new type of protective device for ladle argon pipeline, including a lower shell 1, a mounting block 2 is slidably connected to the upper surface of the lower shell 1, an upper shell 3 is slidably connected to the upper surface of the lower shell 1, a mounting box 4 is fixedly connected to one side of the outer wall of the lower shell 1, a telescopic rod 5 is fixedly connected inside the mounting box 4, a spring 6 is sleeved on the outer wall of the telescopic rod 5, a sliding plate 7 is fixedly connected to one end of the telescopic rod 5, a clamping block 8 is fixedly connected to one side of the outer wall of the sliding plate 7, a mounting plate 9 is fixedly connected to one side of the outer wall of the upper shell 3, a plug post 10 is fixedly connected to the lower surface of the mounting plate 9, and a clamping assembly 11 is arranged on the inner wall of the plug post 10; the clamping assembly 11 includes a spring 2 1101, the spring 2 1101 is slidably connected to the inner wall of the plug post 10, and both ends of the spring 2 1101 are fixedly connected to the clamping block 2 1102;

[0024] Specifically, the core of the mechanical structure lies in the design of block 1 8 and block 2 1102. These two blocks play a role of fixing and connecting in the equipment. Among them, block 2 1102 is closely connected with spring 2 1101. When block 2 1102 is pressed, spring 2 1101 will shrink, so that block 2 1102 can be retracted into the inside of the plug column 10. This design not only simplifies the disassembly process, but also makes the maintenance of the equipment more convenient. Block 1 8 is closely related to the mounting plate 9. When the mounting plate 9 moves inside the mounting box 4, block 1 8 will move with it, thereby driving the telescopic rod 1 5 to move. This chain reaction enables the sliding plate 7 to drive block 1 8 to shrink, thereby providing space for the passage of the argon gas pipeline. In equipment that requires frequent replacement of argon gas pipelines, the staff first presses block 2 1102 to shrink spring 2 1101 and retract block 2 1102 into the inside of the plug column 10. Then, they pull the upper shell 3 to detach the mounting plate 9 from the inside of the mounting box 4. At this time, the block 8 moves with the movement of the mounting plate 9, driving the movement of the telescopic rod 5, so that the sliding plate 7 drives the block 8 to shrink. Finally, the staff puts the new argon gas pipeline through the lower shell 1 to complete the replacement process.

[0025] Reference Figure 1 and Figure 3 , a left-right symmetrical telescopic rod 2 12 is fixedly connected to the top of the inner wall of the upper shell 3, and a spring 3 13 is sleeved on the outer wall of the telescopic rod 2 12; the lower end of the spring 3 13 is fixedly connected to an arc plate 14, and the upper end of the spring 3 13 is fixedly connected to the top of the inner wall of the upper shell 3; an adjusting screw 18 is threadedly connected to the inside of the upper shell 3, and a clamping plate 19 is rotatably connected to the lower surface of the adjusting screw 18; a handle 20 is fixedly connected to the upper surface of the adjusting screw 18, and the adjusting screw 18 is arranged in the middle of the upper shell 3; a telescopic rod 3 15 is fixedly connected to the bottom of the inner wall of the lower shell 1, and a spring 4 16 is sleeved on the outer wall of the telescopic rod 3 15, and an arc plate 2 17 is fixedly connected to the upper surface of the telescopic rod 3 15; a sealing sleeve 21 is arranged between the lower shell 1 and the upper shell 3, and a gooseneck tube 22 is fixedly connected to one side of the outer wall of the sealing sleeve 21;

[0026] Specifically, first, the device uses the gooseneck tube 22 to make the direction of the argon pipeline adjustable at will. The design inspiration of the gooseneck tube 22 comes from the neck of the goose in nature. With its unique flexibility and curvature, the argon pipeline can easily adapt to various complex working environments. Next, the device provides stable support for the argon pipeline through the close combination of the upper shell 3 and the lower shell 1. In this process, the clever cooperation of the telescopic rod 2 12 and the spring 3 13 plays a key role. Together, they push the argon pipeline to abut against the outer wall of the arc plate 2 17 to ensure the stability of the pipeline. In order to further enhance the stability of the argon pipeline, the device also cleverly uses the cooperation of the telescopic rod 3 15 and the spring 4 16. The cooperation of the two not only enhances the firmness of the pipeline fixation, but also effectively reduces the influence of external factors such as vibration and temperature changes on the pipeline. Finally, the device rotates the adjustment screw 18 inside the upper shell 3 by turning the handle 20, thereby realizing the precise adjustment of the clamping plate 19. The resistance of the clamping plate 19 enables the argon gas pipeline to be firmly fixed, ensuring its stability and safety during operation.

[0027] Working principle: When the protective device is needed to protect the argon gas pipeline, the second card block 1102 is pressed to shrink the second spring 1101, thereby achieving the effect of facilitating the card block 1102 to retract into the inside of the plug column 10. At this time, the upper shell 3 is pulled to make the mounting plate 9 detach from the inside of the mounting box 4. At this time, the card block 18 will move through the movement of the mounting plate 9, thereby achieving the effect of driving the telescopic rod 15 to move, so that the sliding plate 7 drives the card block 18 to shrink. At this time, the argon gas pipeline is passed through and placed in the lower shell 1;

[0028] Secondly, by passing the argon pipeline through the gooseneck tube 22, the direction of the pipeline can be adjusted at will through the gooseneck tube 22. At this time, by installing the upper shell 3 on the outer wall of the lower shell 1, the argon pipeline is pushed against the outer wall of the arc plate 2 17 through the cooperation of the telescopic rod 2 12 and the spring 3 13, and then the telescopic rod 3 15 and the spring 4 16 cooperate to further stabilize the argon pipeline. At this time, by turning the handle 20, the adjusting screw 18 is rotated inside the upper shell 3, so as to achieve the effect of making the clamping plate 19 contact the argon pipeline and fix it.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can 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 should be included in the protection scope of the present invention.
