Preferably, described valve hole is located at the bottom, rear end of described housing.
Preferably, air inlet place of described valve cock is provided with filter.
Preferably, described filter comprises the coarse filtration net that sets gradually from outside to inside, thin screen pack and spongy layer.
For solving above-mentioned second technical problem, technical scheme of the present invention is: a kind of video camera leak detection method may further comprise the steps:
A. determine to meet the standard camera of setting the IP degree of protection, give the housing inner chamber inflation of described standard camera by the valve cock of described standard camera, until reaching air pressure U1, the valve cock of described standard camera is connected to pressure test device, air pressure to the housing inner chamber of described standard camera detects, the air pressure that measures the housing inner chamber of described standard camera drops to the time T of U2 from U1, is set to be the standard time;
B. by the valve cock of video camera to be measured the housing inner chamber of described video camera to be measured is inflated, until reaching air pressure U1, the valve cock of described video camera to be measured is connected to pressure test device, air pressure to the housing inner chamber of described video camera to be measured detects, and the air pressure that measures the housing inner chamber of described video camera to be measured drops to the time T 1 of U2 from U1;
C. time T 1 and standard time T are compared, if T1 more than or equal to T, then video camera to be measured is qualified, if T1 less than T, then video camera to be measured is defective.
After having adopted technique scheme, the invention has the beneficial effects as follows:
Because bottom, the rear end of the housing of video camera of the present invention has the valve hole that is communicated with described housing inner chamber and described outside, described valve hole is equipped with valve cock.Therefore when it being leaked hunting detection, determine to meet the standard camera of setting the IP degree of protection earlier, give the housing inner chamber inflation of described standard camera by the valve cock of described standard camera, until reaching air pressure U1, the valve cock of described standard camera is connected to pressure test device, air pressure to the housing inner chamber of described standard camera detects, and the air pressure that measures the housing inner chamber of described standard camera drops to the time T of U2 from U1, is set to be the standard time; Valve cock by video camera to be measured is inflated the housing inner chamber of video camera to be measured, until reaching air pressure U1, the valve cock of described video camera to be measured is connected to pressure test device, air pressure to the housing inner chamber of described video camera to be measured detects, and the air pressure that measures the housing inner chamber of described video camera to be measured drops to the time T 1 of U2 from U1; Time T 1 and standard time T are compared, if T1 more than or equal to T, then video camera to be measured is qualified, if T1 less than T, then video camera to be measured is defective.
To sum up, video camera of the present invention, can adopt the detection of leaking hunting of its method that detects gas leakage, when it being leaked hunting detection, can not cause damage to video camera because of water inlet, therefore can pursue platform to every batch of video camera checks its dustproof and waterproof quality, and it is qualified to determine whether every video camera seals.Having solved present video camera leaks hunting and detects the problem that can only inspect by random samples.
