[0017] In the drawing: verification rod body 1, lockable movable joint 2, detection gas funnel 3, air hose 4, standard gas tank 5, carrier gas joint 6, gas alarm instrument 7, signal connection line 8, signal port 9, data display 10. DETAILED DESCRIPTION

[0018] As shown in Figure 1 and 2 , the gas alarm instrument verification system, the verification system comprises a verification rod body 1 and a standard gas tank 5, the verification rod body 1 is a hollow rod body, the verification rod body 1 is provided with a lockable movable joint 2, one end of the verification rod body 1 is provided with a carrier gas joint 6, and the other end of the verification rod body 1 is provided with a detection gas funnel 3.

[0019] When verifying, the carrier gas joint 6 is connected with the gas to be verified, the verification gas is led to the gas alarm instrument 7 at the high or low position of the detection gas funnel 3 through the rod body, and then whether it is accurate is judged through the data on the gas alarm instrument 7, and the direction of the rod body can be adjusted through the lockable movable joint 2.

[0020] The above-mentioned verification rod body 1 is provided with an air hose 4, and the two ends of the air hose 4 are connected with the detection gas funnel 3 and the carrier gas joint 6 respectively.

[0021] The air hose 4 makes the gas channel not affected by the adjustment of the lockable movable joint 2, and can prevent gas leakage.

[0022] The above-mentioned lockable movable joint 2 is provided with a plurality of lockable movable joints 2 on the verification rod body 1.

[0023] The above-mentioned carrier gas joint 6 is detachably connected with the standard gas tank 5.

[0024] The gas in the standard gas tank 5 is used to verify the gas alarm instrument 7.

[0025] The above-mentioned verification system further comprises a data display 10, and the data display 10 is connected with the gas alarm instrument 7 to be verified through a signal connection line 8 and a signal port 9.

[0026] As shown in Figure 4As shown, in the preferred embodiment, the data display 10 is fixed to the end of the verification rod 1 for easy carrying and viewing.

[0027] The data from the gas alarm 7 can be transmitted to the inspection personnel via the data display 10, allowing for remote viewing when it is inconvenient to check the gas alarm 7.

[0028] Example 1:

[0029] like Figure 2 and 3 The diagram shows the connection between the data display and the signal port. Data transmission and exchange are performed via the RS485 communication protocol. The data display has a 7-segment digital display used to show the detection data of the gas alarm 7. Data exchange is performed with the RS485 communication chip via three signal lines: R1, T1, and W1.
