[0002] A gas analyzer is a device that uses sensors to detect the various gas components and contents in the air. When in use, air is drawn into the detection chamber inside the instrument, and then the air is detected using the sensors inside the detection chamber. However, during long-term use, the sensors are prone to aging and damage, so they need to be regularly maintained and calibrated.

[0003] The traditional method is to pass standard gas into the analyzer, and the various air components and content of the standard gas are known. By comparing the analyzer test data with the actual data, it is possible to understand whether the analyzer has a fault. The existing detection process usually uses a connecting pipe to connect the calibration equipment to the analyzer, and then inject standard gas into the analyzer through the calibration equipment. The installation process is relatively cumbersome, and the release process is prone to leakage. At the same time, the operation is inconvenient, and it is not convenient to perform continuous batch calibration of multiple analyzers. For this purpose, a gas analyzer calibration device is specially provided to solve the above problems. Utility Model Content

[0007] Preferably, a display screen and a control switch are fixedly mounted on the top surface of the calibration frame, and the control switch is used to control the opening and closing of the gas cylinder.

[0008] Preferably, a sliding groove is provided on the inner wall of the bottom end of the lifting support member, and anti-slip blocks are fixedly provided on both sides of the lifting seat, and the anti-slip blocks are slidably connected in the sliding groove.

[0009] Preferably, a positioning hole is provided on the lower surface of the lifting seat, and the top end of the lifting spring is movably inserted into the positioning hole.

[0010] Preferably, the fixed latch member includes L-shaped support blocks slidably arranged inside the two ends of the lifting seat, and racks are fixedly arranged on opposite sides of the two groups of L-shaped support blocks.

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0020] The embodiment of the present application solves the problem that the existing detection process lacks a dedicated calibration instrument by providing a gas analyzer calibration device. Usually, the gas cylinder is connected to the analyzer to release the gas, which is prone to leakage during the release process. At the same time, the operation is inconvenient and it is not convenient to perform continuous batch calibration of multiple analyzers.

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] The embodiment of the utility model discloses a gas analyzer calibration device.

The inner bottom of the calibration frame 1 is provided with a lifting support member 6, and the lifting support member 6 includes;

[0024] The lifting seat 61 and the lifting spring 64 are arranged at the bottom of the lifting seat 61. The lifting seat 61 and the lifting spring 64 are vertically slidably arranged at the inner bottom of the calibration frame 1. A fixed latch part 65 is arranged inside the lifting seat 61, and the two ends of the fixed latch part 65 are against the upper surface of the bottom end of the calibration frame 1.

[0025] Press the lifting seat 61 downward to compress the lifting spring 64. At this time, plug the gas analyzer under the gas outlet 5, and then move the lifting seat 61 upward so that the fixed latch 65 is stuck on the upper surface of the bottom end of the calibration frame 1 to support the gas analyzer, thereby facilitating the continuous calibration and testing of multiple gas analyzers. It is easy to operate and less likely to cause gas leakage.

[0026] A display screen 3 and a control switch 4 are fixedly installed on the top surface of the calibration frame 1. The control switch 4 is used to control the opening and closing of the gas cylinder 2. Solenoid valves are respectively provided between the gas cylinder 2 and multiple gas outlets 5 for injecting standard gas into the corresponding gas outlets 5 of the gas cylinder 2.

[0027] A sliding groove 7 is provided on the inner wall of the bottom end of the lifting support 6, and anti-slip blocks 62 are fixedly provided on both sides of the lifting seat 61. The anti-slip blocks 62 are slidably connected to the sliding groove 7 to prevent the lifting seat 61 from deflecting and slipping when sliding up and down.

[0028] A positioning hole 63 is formed on the lower surface of the lifting seat 61 , and the top end of the lifting spring 64 is movably inserted into the positioning hole 63 to prevent the lifting spring 64 from deflecting.

[0029] The fixed latch member 65 includes an L-shaped support block 651 slidably arranged inside the two ends of the lifting seat 61, and a rack 652 is fixedly arranged on the opposite sides of the two groups of L-shaped support blocks 651. A connecting gear 653 is rotatably arranged inside the lifting seat 61, and the two sides of the connecting gear 653 are respectively engaged with the two groups of racks 652. A sliding shaft 654 is fixedly provided on the end of the connecting gear 653 away from the L-shaped support block 651. A return spring 655 is movably sleeved on the outer surface of the sliding shaft 654, and the end of the sliding shaft 654 is movably inserted into the inside of the L-shaped support block 651 on the opposite side.

[0030] In actual use, by pressing the L-shaped support block 651 on one side, the L-shaped support block 651 drives the connecting gear 653 to rotate through the rack 652, thereby driving the other set of L-shaped support blocks 651 to move synchronously to the middle through the rack 652 on the other side, and shrinking into the inside of the lifting seat 61, so that the two sets of L-shaped support blocks 651 can be quickly retracted when in use. When in use at the same time, the two sets of L-shaped support blocks 651 support from both sides, which is more stable and firm.
