Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of preferred embodiment of the present utility model.
Detailed description of the invention
Being described in further detail this utility model presently in connection with drawings and Examples, these accompanying drawings are simplification
Schematic diagram, illustrates basic structure of the present utility model the most in a schematic way, and therefore it only shows the structure relevant with this utility model
Become.
As it is shown in figure 1, a kind of leak-checking apparatus, the top board 4 including multiple legs 2, being arranged on leg 2, backing plate 6 and control
Device 8, top board 4 is provided with cylinder 10, and backing plate 6 is positioned at the lower section of top board 4, and tested horn bulb is placed on backing plate 6, backing plate 6
On multiple installing hole 11 is set, multiple locating piece (not shown)s are fastened on tested horn bulb clamping on installing hole 11
Living, be provided with multiple column 12 between top board 4 and backing plate 6, column 12 is arranged with support plate 14, cylinder 10 is fixed with support plate 14,
Support plate 14 connects has closing component, closing component to include depression bar 16, the pressure head 18 being fixed on depression bar 16 free end, preferred head pressure
18 is cylindrical, and pressure head 18 connects trachea 20, and trachea 20 connects air pump 22, and trachea 20 is provided with pressure transducer 24,
It is fixed with cylindrical drum 26 on column 12, between cylindrical drum 26 and support plate 14, is provided with spring 28, so, support plate 14 band dynamic head 18
Cushioning effect can be played, it is to avoid pressure head 18 quickly presses to, during shell, shell is caused damage, it is ensured that the matter of shell when pressing to shell
Amount, cylinder 10, air pump 22, pressure transducer 24 are all connected with controller 8.
Being arranged with inverted T-shaped cylinder 30 on the preferred column of this utility model 12, inverted T-shaped cylinder 30 abuts with the upper end of spring 28, this
