The testing device 6 is placed on the positioning plate 7, and the testing tube 61 is limited and fixed by the positioning plate 7. The sliding plate 8 is pushed to push the testing device 6 on the positioning plate 7 into the protective shell 2. The workbench 1 and the protective shell 2 form a relatively closed space.

[0017] The outer surface of the protective shell 2 is fixedly connected with a fixing column 5, and the outer surface of the fixing column 5 is rotatably connected with a hook 4. The upper surface of the workbench 1 is slidably connected with a sliding plate 8, and the upper surface of the sliding plate 8 is fixedly connected with a positioning plate 7, and the upper surface of the sliding plate 8 is slidably connected with a sliding block 9, and the inner surface of the sliding block 9 is fixedly connected with a fixing device 10. The inner surface of the positioning plate 7 contacts the outer surface of the detection tube 61, and the inner surface of the detection tube 61 is threadedly connected with the outer surface of the gas meter 64 through the fixing hole 66, and is connected to the external ventilation pipe through the slot on the protective shell 2. The ventilation The tube is connected to the inflation tube 63. At this time, the door panel 3 is closed, and the hook 4 on the movable fixing column 5 is used to make the hook 4 hang on the door panel 3. At this time, the door panel 3, the protective shell 2 and the workbench 1 form a relatively closed space. The detection tube 61 is inflated through the inflation tube 63. The gas fills the ventilation groove 65 in the detection tube 61 and flows to each valve 62 to be detected. The inflation rate is controlled by observing the gas meter 64. When an unqualified valve 62 to be detected is detected, the valve 62 to be detected will be collapsed by the airflow, and the collapsed valve 62 to be detected will collide with the inner wall of the protective shell 2.

[0018] The fixing device 10 includes a push plate 101, the outer surface of the push plate 101 is fixedly connected to a guide cylinder 102, the inner surface of the guide cylinder 102 is slidably connected to a double-headed push rod 103, the inner surface of the guide cylinder 102 is slidably connected to a magnetic rod 104, the outer surface of the magnetic rod 104 is slidably connected to a magnetic slider 105, the outer surface of the magnetic slider 105 is rotatably connected to a rotating plate 106, the end of the rotating plate 106 away from the magnetic slider 105 is slidably connected to the inner surface of the push plate 101, a limiting block 107 is arranged on the outside of the magnetic rod 104, and the magnetic rod 104 is slidably connected to the inner surface of the push plate 101. 4 is fixedly connected with a compression spring 108, a return spring 109 is arranged below the compression spring 108, the end of the rotating plate 106 away from the magnetic slider 105 is slidably connected with the inner surface of the push plate 101, the end of the compression spring 108 away from the magnetic rod 104 is fixedly connected with the inner surface of the push plate 101, one end of the return spring 109 is fixedly connected with the outer surface of the limit block 107, the other end of the return spring 109 is fixedly connected with the outer surface of the double-headed push rod 103, the outer surface of the magnetic slider 105 is slidably connected with the inner surface of the push plate 101 The outer surface of the limit block 107 is fixedly connected to the inner surface of the positioning plate 7, and the outer surface of the push plate 101 is fixedly connected to the inner surface of the sliding block 9. The push plate 101 approaches the positioning plate 7 until it contacts the positioning plate 7. In the process of the push plate 101 approaching the positioning plate 7, the magnetic rod 104 in the guide cylinder 102 contacts the double-headed push rod 103. Compared with the compression spring 108 that pushes the magnetic rod 104, the reset spring 109 is more difficult to be compressed. Since compressing the reset spring 109 requires a greater force Therefore, the compression spring 108 is compressed under the extrusion of the push plate 101 and the double-headed push rod 103. Before the compression spring 108 is compressed, the magnetic slider 105 is at a relatively slender position of the magnetic rod 104. When the magnetic rod 104 is pushed to squeeze the compression spring 108, the magnetic slider 105 is moved out by the magnetic rod 104, and the magnetic slider 105 lifts the rotating plate 106. At this time, the magnetic slider 105, the rotating plate 106 and the push plate 101 form a triangle, and cooperate with the limit block 107 to limit the movement of the limit block 107 in the direction of the test device 6.

[0019] Working principle:

[0020] When in use, the valve 62 to be tested is twisted into the test tube 61, and the gas meter 64 is installed in the fixing hole 66 of the test tube 61. The test device 6 is placed on the positioning plate 7, and the test tube 61 is fixed by the positioning plate 7. The sliding plate 8 is pushed to push the test device 6 on the positioning plate 7 into the protective shell 2. The workbench 1 and the protective shell 2 form a relatively closed space. The ventilation pipe from the outside is connected through the slot on the protective shell 2. The ventilation pipe is connected to the inflation pipe 63. At this time, the door panel 3 is closed, and the movable fixing column 5 is moved. The hook 4 on the door panel 3 is hooked on the hook 4. At this time, the door panel 3, the protective shell 2 and the workbench 1 form a relatively closed space. The detection tube 61 is inflated through the inflation tube 63. The gas fills the ventilation groove 65 in the detection tube 61 and flows to each valve 62 to be detected. The inflation rate is controlled by observing the gas meter 64. When an unqualified valve 62 to be detected is detected, the valve 62 to be detected will be collapsed by the airflow, and the collapsed valve 62 to be detected will collide with the inner wall of the protective shell 2 to protect the external testers.

[0021] A fixing device 10 is provided. When the sliding block 9 is pushed to fix the position of the test device 6, the push plate 101 approaches the positioning plate 7 until it contacts the positioning plate 7. In the process of the push plate 101 approaching the positioning plate 7, the magnetic rod 104 in the guide cylinder 102 contacts the double-headed push rod 103. Compared with the compression spring 108 that pushes the magnetic rod 104, the reset spring 109 that pushes the double-headed push rod 103 is more difficult to be compressed. Since compressing the reset spring 109 requires a greater force, the compression spring 108 is compressed under the pressure of the push plate 101 and the double-headed push rod 103. Before the compression spring 108 is not compressed, the magnetic slider 105 is in a relatively slender position of the magnetic rod 104. When the magnetic rod 104 is pushed to squeeze the compression spring 108, the magnetic slider 105 is moved out by the magnetic rod 104. The magnetic slider 105 lifts up the rotating plate 106. At this time, the magnetic slider 105, the rotating plate 106 and the push plate 101 form a triangle, and cooperate with the limit block 107 to limit the movement of the limit block 107 in the direction of the test device 6. When the door panel 3 is closed, the door panel 3 limits the movement of the limit block 107 away from the test device 6, so that the sliding block 9 stably clamps the test device 6 and prevents it from being moved by the reaction force of the airflow. When it is necessary to release the fixation, press the head extending from the bottom of the double-headed push rod 103 so that the double-headed push rod 103 no longer squeezes the magnetic rod 104. The magnetic rod 104 is pushed by the compression spring 108 after being squeezed, so that the slender position is again fitted with the magnetic slider 105. The magnetic slider 105 that falls back into the push plate 101 pulls the rotating plate 106 to fit the push plate 101, so that the fixing device 10 no longer fixes the position of the sliding block 9.
