Fig. 1 is structural representation of the present utility model;
Among the figure: 1, base, 2, lid, 3, the base seal bar, 4, sense channel, 5, pressure head, 6, cavity, 7, thimble, 8, the thimble groove, 9, end cap, 10, spring, 11, the pressure head passage, 12, the thimble passage, 13, the pressure head sealing strip.
Embodiment
Below by specific embodiment the utility model lid leak-checking apparatus is described in further detail.
As shown in Figure 1, the lid leak-checking apparatus, comprise a base 1 that is used for placing required detection lid 2, be provided with base seal bar 3 in described base 1 and the lid 2 contacted positions, the base 1 that is arranged under the lid 2 is provided with sense channel 4, sense channel 4 is connected with the pressure transducer (not shown), the top of base 1 is provided with pressure head 5 moving up and down, the bottom of pressure head 5 is provided with the cavity 6 that matches with lid 2, be provided with venting channels in the pressure head 5, one end of venting channels connects cavity 6, the other end of venting channels connects the compressed air source (not shown), is provided with thimble 7 in the pressure head 5, when pressure head 5 is in pressed status, the lower edge of pressure head 5 is tightly connected mutually with base 1, and thimble 7 is inconsistent with lid 2.
As preferred version, be provided with thimble groove 8 in the described pressure head 5, the top of thimble 7 is T-shaped structure, the outer cover of thimble 7 is provided with the end cap 9 that fixes with pressure head 5, the top of thimble 7 is fastened in the thimble groove 8 by end cap 9, also be provided with spring 10 in thimble groove 8, the two ends of spring 10 are inconsistent with the top of the upper end of thimble groove 8 and thimble 7 respectively.Described venting channels comprises the pressure head passage 11 that is arranged in the pressure head 5 and the thimble passage 12 that is arranged in the thimble 7, and the two ends of pressure head passage 11 are bottom and the compressed air source of connecting ejector pin groove 8 respectively, and the two ends of thimble passage 12 are connecting ejector pin groove 8 and cavity 6 respectively.
As preferred version, be provided with pressure head sealing strip 13 in the lower edge of described pressure head 5.Thereby when pressure head 5 was in pressed status, the lower edge of pressure head 5 can be tightly connected mutually with base 1.Certainly, the Hermetical connecting structure between these pressure head 5 lower edge and the base 1 also can substitute with other Hermetical connecting structures commonly used, as sealing strip being arranged in the relevant position of base 1, all belongs to protection category of the present utility model.
Principle of work of the present utility model is: during use, the lid 2 of required detection is arranged on as shown in Figure 1 position, pressure head 5 presses down, the lower edge of pressure head 5 is tightly connected mutually with base 1, and make between the lower edge of lid 2 and the base 1 by thimble 7 and to be tightly connected, at this moment, the inner chamber of lid 2 is connected with pressure transducer by sense channel 4, thimble 7 is because inconsistent with lid 2, the top of thimble 7 is higher than pressure head passage 11, so that pressure head passage 11 is connected with thimble passage 12, pressurized air in the compressed air source enters in the cavity 6 of pressure head 5 by behind pressure head passage 11 and the thimble passage 12, increase along with cavity 6 Air pressure, have leak source such as lid 2, then pressurized air can enter from leak source the inner chamber of lid 2, and this moment, pressure transducer detected the rising of air pressure, represent that then there is leak source in this lid 2, belongs to unacceptable product.Can't detect the rising of air pressure such as pressure transducer, represent that then there is not leak source in this lid 2, belongs to certified products.After detection was finished, pressure head 5 rose, and thimble 7 is moved downward to the bottom in thimble 7 chambeies under the effect of spring 10, thereby pressure head passage 11 no longer is communicated with thimble passage 12, can prevent compressed-air actuated leakage in the compressed air source.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
