Abstract
The utility model relates to a kind of diaphragm gas meter upper cover with anti-corrosion structure, comprise body, on front side of body, mounting groove is set, reading display device is set in mounting groove, arrange the convex edge of assembling around reading display device, reading display device is connected with mounting groove by anti-corrosion structure.Diaphragm gas list structure is simple, and easy to use, production cost is low.The setting of anti-corrosion structure, is isolated from the outside screw, avoids the dust blocking at screw place as much as possible, the more important thing is the corrosion avoiding screw as much as possible.
Description
Technical field
The present invention relates to gas meter, flow meter technical field, particularly relate to a kind of diaphragm gas meter upper cover with anti-corrosion structure.
Background technology
Diaphragm gas meter comprises, housing, reading display device is fixed with on front side of this case top lid, this reading display device is all generally be fixed by screws in the mounting groove on front side of upper cover, and screw generally all exposes, and gas meter, flow meter is generally all exposed in unlimited environment, therefore, screw place is easily blocked by dust, and produces corrosion phenomena, unfavorable for follow-up inspection operation.
Summary of the invention
For the problems referred to above that prior art exists, it is simple that the object that wood is invented is to provide a kind of structure, easy to use, production cost is low, can also prevent the diaphragm gas meter upper cover with anti-corrosion structure of the screw generation corrosion phenomena for fixing reading display device as much as possible simultaneously.
For achieving the above object, the present invention adopts following technical scheme: a kind of diaphragm gas meter upper cover with anti-corrosion structure, comprise body, described bodies top arranges air intake opening and gas outlet, described bodies top and between described air intake opening and gas outlet, gas-flow is set to arrow, on front side of described body, mounting groove is set, reading display device is set in described mounting groove, the convex edge of assembling is set around described reading display device, described reading display device is connected with mounting groove by anti-corrosion structure, anti-corrosion structure has: the first mounting hole, it is arranged in four bights of described mounting groove, the top, outer end of described first mounting hole arranges permanent magnet, second mounting hole, it is arranged in four bights of described convex edge, and with described first mounting hole one_to_one corresponding, described second mounting hole is closing in taper, capping, it is made up of ferrous material, and described capping is rounded, and cross section is closing in taper, and described closure base portion arranges breach, and described capping is arranged in the oral area of described second mounting hole, and the top of top and described second mounting hole is hinged, first mounting hole coordinates with the second mounting hole and forms pilot hole, arrange trip bolt in described pilot hole, in order to be connected with mounting groove the convex edge of reading display device, capping closes, the bottom of permanent magnet absorption capping, the oral area of capping and pilot hole forms closed structure.
As optimization, in the middle part of described capping, threaded hole is set, in described threaded hole, arranges the screw be made up of elastomeric material.
Compared to existing technology, the present invention has following beneficial effect: the diaphragm gas list structure that the utility model provides is simple, and easy to use, production cost is low.Be arranged on the first mounting hole on mounting groove and be arranged on the second mounting hole formation pilot hole on the convex edge of reading display device, trip bolt is arranged in pilot hole, closure hinge is connected to the top of the second mounting hole, during use, the top of pilot hole seals by capping, thus screw is isolated from the outside, avoid the dust blocking at screw place as much as possible, the more important thing is the corrosion avoiding screw as much as possible.
Accompanying drawing explanation
Fig. 1 is the stereographic map of the diaphragm gas meter upper cover with anti-corrosion structure.
Fig. 2 is the cut-open view that Figure 1A-A locates.
Fig. 3 is the front view of capping.
In figure, reading display device 2, mounting groove 3, permanent magnet 31, air intake opening 11, gas outlet 12, capping 4, trip bolt 5.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further details.
See accompanying drawing 1 to Fig. 3, a kind of diaphragm gas meter upper cover with anti-corrosion structure, comprise body, described bodies top arranges air intake opening 11 and gas outlet 12, described bodies top and between described air intake opening 11 and gas outlet 12, gas-flow is set to arrow, mounting groove 3 is set on front side of described body, reading display device 2 is set in described mounting groove, described reading display device 2 surrounding arranges the convex edge 21 of assembling, described reading display device 2 is connected with mounting groove 3 by anti-corrosion structure, anti-corrosion structure has: the first mounting hole, it is arranged in four bights of described mounting groove 3, the top, outer end of the first mounting hole arranges permanent magnet 31, second mounting hole, it is arranged in four bights of described convex edge 21, and with described first mounting hole one_to_one corresponding, described second mounting hole is closing in taper, capping 4, it is made up of ferrous material, and capping 4 is rounded, and cross section is closing in taper, arranges breach bottom described capping 4, and this breach is convenient to the instruments such as screwdriver and is pushed capping aside.Described capping 4 is arranged in the oral area of described second mounting hole, and the top of top and described second mounting hole is hinged; First mounting hole coordinates with the second mounting hole and forms pilot hole, arrange trip bolt 5 in described pilot hole, in order to be connected with mounting groove 3 convex edge 21 of reading display device, capping 4 closes, permanent magnet 31 adsorbs the bottom of capping 4, and capping 4 forms closed structure with the oral area of pilot hole.
During use, first reading display device 2 is arranged in mounting groove 3, the first mounting hole one_to_one corresponding on four the second mounting holes on 21 4 jiaos, the convex edge of reading display device and mounting groove 3 four angles, screw 5 is arranged in the pilot hole of the first mounting hole and the second mounting hole formation, the top of pilot hole seals by capping 4, screw is isolated from the outside, avoids the dust blocking at screw place as much as possible, the more important thing is the corrosion avoiding screw as much as possible.Because capping 4 is made up of ferrous material, under the attraction of permanent magnet, capping 4 can be enclosed in the top of pilot hole better.
As optimization, in the middle part of described capping 4, threaded hole is set, in described threaded hole, arranges the screw be made up of elastomeric material.After Long-Time Service, negative pressure can be formed in pilot hole and cannot push capping aside, the screw be made up of elastomeric material can be unclamped, can subsequent job be carried out.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
