Description
Technical field
The utility model relates to gas meter, flow meter technical field, specifically a kind of anti-theft gas meter.
Background technology
Along with the development of science and technology, natural gas uses widely industry, business and civilian being obtained for.But some businessmans are under interests drive, privately gas meter, flow meter is overlapped, wherein mostly being the tracheae private of taking off meter connector receives on the pipeline oneself built, the pipeline of putting up in disorder carries out accounting management in Shi Bu aspect gas company on the one hand, the more important thing is that these pipelines do not have safety guarantee, and easily occur reveal thus cause security incident.
Utility model content
The utility model aims to provide a kind of anti-theft gas meter, by providing protection to gas meter connector part, to solve the problem.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of anti-theft gas meter, is characterized in that: comprise gas meter, flow meter, meter connector containment vessel, the meter connector be connected on shell of gas meter; Described meter connector containment vessel comprises the chassis be weldingly fixed on gas meter, flow meter, chassis has the jack of meter connector, offers annular groove in the middle part of jack, be connected with baffle plate in annular groove; Baffle plate is divided into elastic plate and leveling board, and leveling board is provided with hooked scarf; Meter connector containment vessel also comprises the tubular meter connector protective cover be connected in jack, and protective cover excircle is welded with inverted cone fixture block; Be provided with the microswitch controlling air valve and open and close in described gas meter, flow meter, microswitch is connected with Hall element by circuit; Be provided with connecting link bottom described protective cover, connecting link end is provided with can through the permanent magnetism circle of Hall element.
Further, described chassis excircle has adjustment hole.
Further, leveling board slot is offered above described adjustment hole.
The beneficial effects of the utility model are:
One, the utility model in use; the protective cover of tubular is inserted in jack, in downslide process, inverted cone fixture block extruding elastic plate; leveling board is made to insert in leveling board slot; after passing through elastic plate, extruding force disappears, and elastic plate drives leveling board to reset; block inverted cone fixture block; thus make protective cover block, meter connector can cover by protective cover, effectively prevents from privately dismantling.When dismantling, need specific purpose tool to stretch into from adjustment hole, the hooked scarf precipitation flat board caught on leveling board is thought in slot mobile, and elastic plate is not at the main inverted cone fixture block of card, and protective cover could take out.
Two, be provided with the microswitch controlling air valve and open and close in gas meter, flow meter, microswitch is connected with Hall element by circuit; Being provided with bottom described protective cover can through the permanent magnetism circle of Hall element; only have when permanent magnetism circle is through Hall element; microswitch just can be triggered; thus connection gas meter, flow meter; once there be people privately to take protective cover apart; permanent magnetism circle departs from the some position signal interruption of Hall element microswitch, closes gas meter voluntarily, reaches the object preventing from stealing gas.
Accompanying drawing explanation
Fig. 1 is the anti-theft gas meter structural representation that the utility model provides.
Fig. 2 is the close-up schematic view at I place in Fig. 1.
Fig. 3 is the close-up schematic view at J place in Fig. 1.
Mark in figure: 1 be gas meter, flow meter, 2 be chassis, 3 be meter connector, 4 be protective cover, 5 be adjustment hole, 6 be leveling board slot, 7 be elastic plate, 8 be leveling board, 9 be hooked scarf, 10 be inverted cone fixture block, 11 be Hall element, 12 be permanent magnetism circle, 13 for connecting link.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of anti-theft gas meter, is characterized in that: comprise gas meter, flow meter 1, meter connector 3 containment vessel, the meter connector 3 be connected on gas meter, flow meter 1 shell; Described meter connector 3 containment vessel comprises the chassis 2 be weldingly fixed on gas meter, flow meter 1, chassis 2 has the jack of meter connector 3, offers annular groove in the middle part of jack, be connected with baffle plate in annular groove; Baffle plate is divided into elastic plate 7 and leveling board 8, leveling board 8 is provided with hooked scarf 9; Meter connector 3 containment vessel also comprises tubular meter connector 3 protective cover 4 be connected in jack, and protective cover 4 excircle is welded with inverted cone fixture block 10; Be provided with the microswitch controlling air valve and open and close in described gas meter, flow meter 1, microswitch is connected with Hall element 11 by circuit; Be provided with connecting link 13 bottom described protective cover 4, connecting link 13 end is provided with can through the permanent magnetism circle 12 of Hall element 11.Described chassis 2 excircle has adjustment hole 5.Leveling board 8 slot 6 is offered above described adjustment hole 5.
The utility model in use; be inserted in jack by the protective cover 4 of tubular, in downslide process, inverted cone fixture block 10 extrudes elastic plate 7; leveling board 8 is made to insert in leveling board 8 slot 6; after passing through elastic plate 7, extruding force disappears, and elastic plate 7 drives leveling board 8 to reset; block inverted cone fixture block 10; thus make protective cover 4 block, meter connector 3 can cover by protective cover 4, effectively prevents from privately dismantling.When dismantling, need specific purpose tool to stretch into from adjustment hole 5, the hooked scarf 9 precipitation flat board 8 caught on leveling board 8 is thought in slot mobile, and elastic plate 7 is not at the main inverted cone fixture block 10 of card, and protective cover 4 could take out.Be provided with the microswitch controlling air valve and open and close in gas meter, flow meter 1, microswitch is connected with Hall element 11 by circuit; Being provided with bottom described protective cover 4 can through the permanent magnetism circle of Hall element 11; only have when permanent magnetism circle is through Hall element 11; microswitch just can be triggered; thus connect gas meter, flow meter 1; once there be people privately to take protective cover 4 apart; permanent magnetism circle departs from the some position signal interruption of Hall element 11 microswitch, closes gas meter voluntarily, reaches the object preventing from stealing gas.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
