Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a gas testing control device. Background Art

[0002] Before gas is bottled and transported, a gas test control device is needed to test the quality of the gas. The existing gas test device is easy to disassemble, but it is difficult to ensure the internal sealing of the device after the measurement is completed. After the test is completed, the gas will leak from the device and be inhaled by the staff, causing damage to their health. For example, the patent announcement number is CN 219533004 A gas property testing device recorded in U's patent relates to the field of gas property testing technology, including a shielding cover, wherein an operating table is arranged inside the shielding cover. When it is necessary to disassemble the full hard tube, the pull plate is pulled at this time, and the pull plate will drive the clamping rod to move, so that the clamping rod is moved out of the through hole of the second conical head, so that the clamping rod no longer limits the second conical head. At this time, the connecting round tube can be taken out to complete the disassembly. When it is necessary to install the connecting round tube, the first conical head of the connecting round tube is pressed against the arc groove opened by the flange. At this time, the connecting round tube is pressed so that the first conical head enters the groove opened by the flange. At this time, the connecting round tube is rotated to drive the second conical head to move. When the second conical head enters the groove opened by the flange, it will resist the clamping rod. When the clamping rod enters the through hole of the second conical head, the second conical head can be limited. At this time, the flange and the connecting round tube can be stabilized. The existing technology is easy to disassemble, and there is no need to disassemble and assemble the entire device. However, after the measurement is completed, the gas inside the device is easy to leak, which can easily cause damage to the health of the staff.

[0003] Based on this, a gas test control device is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

Detailed implementation manners

[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0024] Embodiment 1

[0025] In one embodiment, as Figures 1 - 5 shown, a gas test control device includes a detection seat 1. A pair of connecting frames 2 are arranged on both sides of the bottom end of the detection seat 1. A bolt 3 is arranged on the surface of one end of the connecting frame 2. A connecting block 4 is arranged on the upper surface of the detection seat 1. The other end of the connecting block 4 is provided with an air valve 5. The transmission speed of the extracted gas is controlled by the air valve 5. The air valve 5 is connected to a detection instrument 6. The detection instrument 6 is used to perform a small amount of extraction test on the gas to be inspected. A plurality of assembly mechanisms are arranged at the bottom end of the detection seat 1. A gas storage mechanism 8 is arranged below the detection seat 1.

[0026] In one embodiment, as Figure 4As shown in the figure, the assembly mechanism includes a fixing component 71 fixedly connected to the bottom end of the detection base 1. The other end of the fixing component 71 is provided with a sealing component 74, and the other end of the sealing component 74 is provided with a reset component 75. The fixing component 71 is correspondingly arranged with the connecting block 4. The fixing component 71 includes a fixing sleeve 711 fixedly connected to the bottom end of the detection base 1. An internal thread 712 is provided at the lower end inside the fixing sleeve 711. A connecting component 73 is provided below the fixing sleeve 711. The other end of the fixing sleeve 711 is provided with a connecting sleeve 72. The connecting component 73 includes a connecting head 731 arranged below the fixing sleeve 711. An external thread 732 is provided at the lower end surface of the connecting head 731. One end of the connecting head 731 away from the fixing sleeve 711 is provided with an adapter block 733. When the user needs to perform gas detection, the connecting head 731 can be inserted into the fixing sleeve 711, and then the connecting head 731 is rotated to make the external thread 732 and the internal thread 712 cooperate and connect, so as to fix the gas delivery pipe 83 at the other end of the connecting head 731 to the bottom end of the detection base 1.

[0027] In one embodiment, as Figure 4 and Figure 5 shown, the sealing component 74 includes a sealing block 741 slidably connected inside the fixing sleeve 711. The size of the sealing block 741 is the same as that of the fixing sleeve 711. The other end of the sealing block 741 is provided with a limiting block 742. The limiting block 742 is slidably connected inside the connecting sleeve 72. The reset component 75 includes a limiting plate 751 fixedly connected inside the connecting sleeve 72. An air hole 753 is opened at the central position of the limiting plate 751. One end of the limiting plate 751 close to the limiting block 742 is connected with a reset spring 752. The other end of the reset spring 752 is fixedly connected to one end surface of the limiting block 742. When the connecting head 731 is connected to the fixing sleeve 711, the top end of the connecting head 731 will push the sealing block 741. At this time, the reset spring 752 is compressed, and the gas can smoothly enter the air valve 5 through the air hole 753 for detection. After the detection is completed, the connecting head 731 is rotated and removed from the inside of the fixing sleeve 711. At this time, the reset spring 752 is reset, and the sealing block 741 fits with the inner wall of the fixing sleeve 711 to ensure the airtightness inside the device and prevent the residual leakage of dangerous gases after gas detection from damaging the body of the user.

[0028] Embodiment 2

[0029] The difference from Embodiment 1 is that, as Figure 1 and Figure 2 shown, the gas storage mechanism 8 includes a gas tank 81 arranged below the detection base 1. A control valve 82 is arranged on the surface of the gas tank 81. The output end of the control valve 82 is fixedly connected with a gas delivery pipe 83. The gas delivery pipe 83 is connected to one end of the adapter block 733. The user controls the gas inside the gas tank 81 to enter the detection mechanism through the gas delivery pipe 83 through the control valve 82 for detection.

[0030] The above embodiment discloses a gas test control device. Among them, the transmission speed of the extracted gas is controlled by the gas valve 5, and a small amount of the gas to be tested is extracted and tested by the detection instrument 6. When the user needs to perform gas detection, the connector 731 can be inserted into the fixed sleeve 711, and then the connector 731 is rotated so that the external thread 732 and the internal thread 712 are engaged and connected, achieving the purpose of fixing the gas pipeline 83 at the other end of the connector 731 to the bottom end of the detection seat 1. The connection is firm. When the connector 731 is connected to the fixed sleeve 711, the top end of the connector 731 will push the sealing block 741, and at this time, the return spring 752 is compressed, and the gas can smoothly enter the gas valve 5 through the air hole 753 for detection. After the detection is completed, the connector 731 is rotated and removed from the inside of the fixed sleeve 711. At this time, the return spring 752 is reset, and the sealing block 741 fits against the inner wall of the fixed sleeve 711, ensuring the tightness inside the device and preventing the residual leakage of dangerous gases after gas detection from damaging the body of the user.

[0031] As described above, the above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered within the protection scope of the present disclosure.
