[0002] The airtightness test of security cameras is conducted by using a security camera airtightness tester. The principle is: the security camera placed in the sealed cavity is inflated through a pressure valve, and the air pressure value is determined according to the volume of the space in the sealed cavity; when the security camera airtightness tester reaches the standard value, the gas source is cut off to ensure that the constant air pressure in the sealed cavity is stable for a period of time; after the air pressure is stable, the test phase begins, and the pressure sensor of the security camera airtightness tester records the current pressure value in real time; after a period of testing, the real-time pressure value in the sealed cavity will be recorded according to the test time of the sample standard; the pressure difference between the two pressure values ​​is compared, and the intelligent leakage detection system of the security camera airtightness tester is analyzed and calculated to determine whether the product has leakage. Its purpose is to detect whether the waterproof performance and sealing performance of the sample meet the qualified standards.

[0003] At present, when performing an airtight test on a security camera, the airtightness of the security camera shell can only be tested by using the principle of air pressure. It is impossible to effectively mark the leaking parts of the security camera shell. As a result, when personnel repair the security camera shell, they need to find the leaking points of the security camera shell before they can repair the security camera shell, which increases the labor burden of the personnel. Based on this, an airtight test device and method for a security camera are proposed. Summary of the invention

When the magnetic plate 29 is separated from the position of the magnetic block 31, the magnetic block 31 will suddenly slide inwards under the action of the second spring 33, and push the knocking ball 35 to knock on the shell 2 through the connecting rod 32. At this time, the knocking ball 35 will vibrate. The vibration generated by the knocking ball 35 will make the vibration ring 36 vibrate, thereby driving the air blowing pipe 18 to vibrate. When the exhaust pipe 26 on this side stops taking in air, the slide plate 28 will reset under the action of the first spring 30, thereby driving the magnetic plate 29 to reset, so that the magnetic block 31 slides outwards under the adsorption of the magnetic plate 29, and then the knocking ball 35 is separated from the shell 2 through the connecting rod 32. The impact of birds under normal use of the outer shell 2 is simulated, and the force of the knocking ball 35 is smaller than the force of the external bird impact. When the outer shell 2 is squeezed by the specified air pressure, the knocking can further promote the airtight detection of the outer shell 2. If the outer shell 2 leaks when it is knocked by the knocking ball 35 under the condition of specified air pressure, the airtightness of the surface outer shell 2 does not meet the production requirements. At the same time, when the knocking ball 35 knocks on the outer shell 2, it can cause the outer shell 2 to vibrate slightly, and the dust blown down by the air pipe 18 is shaken off the outer shell 2. The vibration generated by the knocking ball 35 when knocking will be transmitted to the air pipe 18 along the vibration ring 36, and the dust and other impurities attached to the outer surface of the air pipe 18 will be cleaned off, so as to prevent the dust and other impurities from adhering to the air pipe 18 and causing the dust and other impurities to scratch the outer shell 2, thereby affecting the aesthetics of the outer shell 2, thereby improving the cleaning quality of the outer shell 2 and ensuring the quality of the airtight detection of the outer shell 2.
