Description

Technical Field

[0001] This utility model relates to the field of gas detection and calibration technology, and in particular to a carbon monoxide detection alarm calibration device. Background Technology

[0002] A carbon monoxide detector alarm is a device specifically designed to detect the concentration of carbon monoxide in the air. When the carbon monoxide concentration exceeds a set safety value, the alarm will emit an audible and visual alarm signal to remind people to take appropriate measures to avoid carbon monoxide poisoning accidents. To ensure the accuracy of the alarm, a calibration device is usually used to calibrate it. Users should note that a carbon monoxide detector alarm calibration device is a device used to ensure that the carbon monoxide detector alarm accurately measures the carbon monoxide concentration. It compares the alarm reading with the actual concentration of a standard gas, thereby adjusting the alarm's measurement accuracy to ensure that it responds accurately within a safe range.

[0003] Currently, most carbon monoxide detection alarm calibration devices are used when carbon monoxide is a toxic gas that is colorless and odorless. It is stored in a storage bottle. If the storage bottle is damaged during the detection process and leakage occurs, it can easily be inhaled by staff, leading to poisoning and injury.

[0004] Therefore, how to design a carbon monoxide detection alarm calibration device that protects workers and prevents carbon monoxide leaks is a technical problem that technicians need to solve. Utility Model Content

By using an arc-shaped cover and a spherical cover in cooperation, the storage bottle can be wrapped. When the airbag compresses the arc-shaped cover and the spherical cover, the problem mentioned in the background art is effectively solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carbon monoxide detector alarm calibration device, comprising a connecting frame, two storage bottles and two protective sleeves, wherein the two protective sleeves are respectively disposed on both sides of the connecting frame, and the front end face of the connecting frame is provided with a detector alarm calibration structure;

[0007] Both of the inner walls of the sheaths are provided with a set of airbags, and each set of airbags is connected to a set of sealing components to wrap and seal the corresponding storage bottle to prevent gas from leaking out and affecting the accuracy of the detection alarm calibration results.

[0008] It also includes:

[0009] Two sets of filling components are set on corresponding sheaths to pump air into the two sets of airbags, causing them to expand and enabling the compression sealing components to move towards the center and fit tightly against the storage bottle.

[0010] Preferably, the sealing assembly includes two arc-shaped covers disposed on each group of airbags, each arc-shaped cover having a spherical cover rotatably disposed on it, and both the arc-shaped covers and the spherical covers having a sealing layer disposed on them and tightly fitting against the surface of the storage bottle.

[0011] Preferably, the filling component includes a compression balloon and a connector disposed on the inner wall of the sheath, wherein the output end of the connector is connected to the balloon, and the output end of the compression balloon passes through the sheath and is connected to the connector.

[0013] Preferably, one end of each of the two springs is connected to the inner wall of the groove, and the other end is connected to the limiting sleeve.

[0014] Preferably, the connecting frame is provided with a connecting valve, the input ends on both sides of the connecting valve are connected to two storage bottles, and the output end of the connecting valve is connected to the calibration structure of the detection alarm.

[0015] Preferably, the two storage bottles contain equal volumes of carbon monoxide gas and air, respectively.

[0016] Preferably, the spherical cover rotates upwards by an angle of 0 to 45 degrees.
