[0002] Point gas detectors are instruments used to detect gas leaks and are usually installed in places where gas leaks may occur, such as chemical plants, oil depots, gas pipelines, etc. When gas leaks, the detector will immediately sound an alarm to remind relevant personnel to deal with it in time to avoid accidents. In order to ensure the accuracy of its measurement and the safety of users, point gas detectors need to be calibrated and tested before they are produced;
[0003] When calibrating and testing current gas detectors, it is necessary to plug the connecting pipes of the standard gas into the detection channel of the gas detector one by one. If the concentration displayed by the detector is inconsistent with the concentration of the standard gas, it can be corrected by adjusting the parameters of the detector or performing zero and span calibration. Since gas detector manufacturers produce a large number of detectors at one time, performing calibration and testing one by one will affect the factory efficiency of point-type gas detectors to a certain extent.

[0025] When calibrating and testing current gas detectors, it is necessary to plug the connecting pipes of the standard gas into the detection channels of the gas detectors one by one. If the concentration displayed by the detector is inconsistent with the concentration of the standard gas, it can be corrected by adjusting the parameters of the detector or performing zero point and span calibration. Since gas detector manufacturers produce a large number of detectors at one time, performing calibration and testing one by one will affect the factory efficiency of point-type gas detectors to a certain extent.

[0027] First, the specific structure of the storage component 2 is disclosed. The storage component 2 includes three storage slots 21 opened at the top of the detection platform 14. The three storage slots 21 are fixedly connected to the inside of the clamping capsule 22. The three clamping capsules 22 are opened inside the clamping compartment 23 for auxiliary storage of gas detectors. By using the three storage slots 21 opened at the top of the detection platform 14, and the clamping capsules 22 are installed inside the three storage slots 21, the three gas detectors can be clamped inside the clamping compartment 23 for simultaneous calibration and detection, which effectively improves the factory calibration efficiency of the gas detector.
[0028] Secondly, the specific structure of the access component 3 is disclosed. The access component 3 includes a four-way pipe 31 connected to the standard gas tank 15. The other end of the four-way pipe 31 is located inside the ventilation hood 11. The other end of the four-way pipe 31 is connected to the movable plate 32. Three extension sleeves 33 are fixedly connected to the bottom of the movable plate 32. The four-way pipe 31 is connected to the three extension sleeves 33, and the three extension sleeves 33 are aligned with the three clamping chambers 23. When it is necessary to transport gas to the gas detector clamped in the three detection clamping chambers 23, the movable plate 32 is moved toward the detection platform 14, driving the extension sleeve 33 to be sleeved on the top of the gas detector. Through the four-way pipe 31, the gas inside the standard gas tank 15 can be transported to the inside of the three gas detectors for calibration and detection, which effectively increases the number of one-time calibrations and then improves the factory efficiency of the gas detector.
[0029] Finally, the specific structure of the starting assembly 4 is disclosed. The starting assembly 4 includes a collar 41 fixedly connected to the side wall of the movable plate 32, a screw 42 is movably connected inside the ventilation hood 11, a starting slot 43 is provided inside the workbench 1, and one end of the screw 42 close to the workbench 1 is fixedly connected to the output shaft of the starting motor 44, the starting motor 44 is installed inside the starting slot 43, and the collar 41 is movably sleeved on the surface of the screw 42. When the gas detector needs to be connected to the gas calibration, the starting motor 44 is turned on to drive the screw 42 fixedly connected to the output shaft of the starting motor 44 to rotate inside the ventilation hood 11, so that the collar 41 sleeved on the surface of the screw 42 moves vertically inside the ventilation hood 11, so that the movable plate 32 is more convenient to move toward the detection platform 14, wherein the collar 41 fixedly connected to the other end of the movable plate 32 slides on the surface of the vertical pole, which effectively improves the sliding stability of the movable plate 32, thereby improving the accuracy of gas access to the gas detector.

When the gas detector needs to be connected to the gas calibration, the starting motor 44 is turned on to drive the screw rod 42 fixedly connected to the output shaft of the starting motor 44 to rotate inside the ventilation hood 11, so that the ring 41 sleeved on the surface of the screw rod 42 moves vertically inside the ventilation hood 11, so that the movable plate 32 can be more convenient to move toward the detection platform 14, and drive the extension sleeve 33 to be sleeved on the top of the gas detector. Through the four-way pipe 31, the gas inside the standard gas tank 15 can be transported to the inside of the three gas detectors for calibration and detection, which effectively increases the number of one-time calibrations and thereby improves the factory efficiency of the gas detector.
[0031] Considering the connection between the extension sleeve 33 and the gas detector when the standard gas is transported to the inside of the gas detector through the four-way pipe 31, in order to further improve the sealing between the extension sleeve 33 and the gas detector, Figure 5 As shown, sealing sleeves 5 are fixedly mounted on the inner walls of the three extension sleeves 33 .
[0032] The improvement lies in that: by setting the sealing sleeve 5 on the inner wall of the extension sleeve 33, when the extension sleeve 33 moves down to be connected to the top of the gas detector, the gap between the gas detector and the extension sleeve 33 can be filled by the sealing sleeve 5, effectively reducing the leakage during gas detection.
[0033] In summary, the working principle of the present invention is as follows: first, three storage slots 21 are provided on the top of the detection platform 14, and the inside of the three storage slots 21 are all equipped with clamping bags 22, so that the three gas detectors can be clamped inside the clamping compartment 23 for simultaneous calibration and detection. When the gas detector needs to be connected to the gas calibration, the starting motor 44 is turned on to drive the screw rod 42 fixedly connected to the output shaft of the starting motor 44 to rotate inside the ventilation hood 11, so that the collar 41 sleeved on the surface of the screw rod 42 moves vertically inside the ventilation hood 11, thereby making the movable plate 32 more convenient to Move toward the detection platform 14, drive the extension sleeve 33 to be connected to the top of the gas detector, and through the four-way pipe 31, the gas inside the standard gas tank 15 can be transported to the inside of the three gas detectors for calibration and detection, which effectively increases the number of one-time calibrations and then improves the factory efficiency of the gas detector. Through the sealing sleeve 5 set on the inner wall of the extension sleeve 33, when the extension sleeve 33 moves down to be connected to the top of the gas detector, the gap between the gas detector and the extension sleeve 33 can be filled by the sealing sleeve 5, which effectively reduces the leakage during gas detection.
