[0002] Specialty gases refer to the general term for gases that meet specific purposes. They include not only single gases but also various mixed gases. There are many types of special gases, which are generally divided into electronic gases, standard gases, environmental protection gases, medical gases, welding gases and sterilization gases, etc. They are widely used in electronics, electricity, petrochemicals, non-ferrous metal smelting, medical research and food preservation.

[0003] Due to the characteristics of some special gases, they generally need to be tested and diluted according to specific needs before use, so that the special gases reach the standard concentration for subsequent use. At this time, a gas diluter is needed. A gas diluter is a device specifically used to test and dilute gases. It can set the concentration and flow rate of the gas. This device is more common in gas dilution work.

[0004] During use, the existing special gas diluter is generally provided with a height-adjustable bracket at the bottom. However, when operating the bracket, the staff is generally required to manually lift the body first, and then adjust the height of the bracket at the bottom of the device, which makes the operation more troublesome.

[0005] Therefore, it is necessary to provide a new diluter for special gas inspection to solve the above technical problems. Utility Model Content

[0031] It should be noted that the machine body 1 can be supported by the cooperation of the base plate 2 and the support frame 11. When the machine body 1 is used, the knob A27 is turned according to the height of the user, and the knob A27 is used to drive the driving wheel 26 to rotate. The driving wheel 26 drives the transmission wheel 23 to rotate by the belt 28. During the rotation of the transmission wheel 23, the screw 22 can be driven to rotate by the telescopic rod 24. When the screw 22 rotates, the machine body 1 can be lifted to adjust the upward viewing angle of the machine body 1. The telescopic rod 24 has a telescopic function, and its telescopic length can be changed with the extension length of the screw 22. When the machine body 1 is used, the knob A27 is turned in the opposite direction, and the driving wheel 26 rotating in the opposite direction is used to drive the transmission wheel 23 to reverse. At this time, the screw 22 can be retracted until the machine body 1 is in a horizontal state.

[0032] In the embodiments of the present invention, please refer to Figure 1 , Figure 6 and Figure 7 Two fixedly connected load-bearing frames 3 are provided on the top of the machine body 1, a rotatably connected winding rod 33 is provided between the load-bearing frames 3, and a threaded groove is provided on the winding rod 33, a fixed arc plate 31 is fixedly connected between the load-bearing frames 3, and a movable arc plate 32 is rotatably connected to the bottom of the fixed arc plate 31, the fixed arc plate 31 and the movable arc plate 32 are both located on the outside of the winding rod 33, a fixed frame 35 is fixedly connected to the top wall of the fixed arc plate 31, and a limiting frame 36 is rotatably connected to the fixed frame 35, a torsion spring 37 is provided at the connection between the limiting frame 36 and the fixed frame 35, a knob B34 for driving the winding rod 33 to rotate is provided on one side of the load-bearing frame 3, and a plurality of anti-slip grooves are provided on the knob B34.

[0033] It should be noted that: when the machine body 1 is not in use, the movable arc plate 32 can be opened, and then the limit frame 36 can be lifted. At this time, the limit frame 36 can tighten the torsion spring 37 during the rotation process, and one end of the air pipe is placed between the limit frame 36 and one end of the winding rod 33. Then, the limit frame 36 is loosened. At this time, the torsion spring 37 drives the limit frame 36 to reset. The limit frame 36 and the winding rod 33 can be used to temporarily clamp and fix one end of the air pipe. Then, the knob B34 is used to drive the winding rod 33 to rotate, and the remaining air pipe can be fixed. After winding, the movable arc plate 32 is closed. At this time, the fixed arc plate 31 and the movable arc plate 32 cooperate to form a cylindrical shape, which can serve as a handle of the body 1, so as to facilitate the picking up and moving of the body 1. When the body 1 is in use, the movable arc plate 32 is opened, and then the limit frame 36 is lifted. Then, one end of the air pipe is held and the air pipe is pulled. During the pulling process of the air pipe, the winding rod 33 can be driven to rotate, thereby completing the picking up of the air pipe. After that, the air pipe is used to connect the gas with the body 1 to carry out the gas inspection and dilution work.

[0034] The working principle of the special gas inspection diluter provided by the utility model is as follows:

[0035] First, place the machine body 1 and power it on, then open the movable arc plate 32, then lift the limit frame 36, then hold one end of the air pipe and pull the air pipe. During the pulling process, the air pipe can drive the reeling rod 33 to rotate, thereby completing the work of taking the air pipe. After closing the movable arc plate 32, use the air pipe to connect the machine body 1 with the gas, and then prepare for the gas inspection and dilution work;

[0036] Before the gas inspection and dilution work is performed, the knob A27 can be turned according to the height of the user, and the knob A27 can be used to drive the driving wheel 26 to rotate. The driving wheel 26 drives the transmission wheel 23 to rotate by using the belt 28. During the rotation of the transmission wheel 23, the screw 22 can be driven to rotate through the telescopic rod 24. When the screw 22 rotates, the body 1 can be driven to lift up and adjust the upward viewing angle of the body 1. After the adjustment is completed, the body 1 can be operated through the touch screen 12 to perform the gas inspection and dilution work, and the gas inspection and dilution results will be displayed on the touch screen 12;

[0037] After the gas test and dilution are completed, the body 1 is closed, the knob A27 is rotated in the opposite direction, and the driving wheel 26 rotating in the opposite direction is used to drive the transmission wheel 23 to reverse. At this time, the screw 22 can be retracted until the body 1 is in a horizontal state, and the air pipe is removed from the body 1, the movable arc plate 32 is opened, and then the limit frame 36 is lifted. At this time, the limit frame 36 can tighten the torsion spring 37 during the rotation process, and one end of the air pipe is placed between the limit frame 36 and one end of the winding rod 33, and then the limit frame 36 is released. At this time, the torsion spring 37 drives the limit frame 36 to reset, and the limit frame 36 and the winding rod 33 can be used to temporarily clamp and fix one end of the air pipe, and then the knob B34 is used to drive the winding rod 33 to rotate, and the remaining air pipe can be wound up, and then the movable arc plate 32 can be closed.
