Abstract
The utility model provides a gas meter for preventing gas from being stolen, which comprises an upper shell, a lower shell, an adnexal shell and a counter cover, wherein the upper shell is provided with a magnet steel hole; the adnexal shell is provided with a transmission hole corresponding to the magnet steel hole; magnet steel is riveted on the magnet steel hole; a transmission mechanism is in rigid connection with a driving gear through a magnetic core; a driven gear engaged with the driving gear is in rigid connection with a counter; points between the adnexal shell and the upper shell are in welded connection; a driving hole of the adnexal shell is folded toward one side of the upper wall to form an edge fold; and the circumference edge of the magnetic hole of the upper shell and the wall of the upper shell relative to the edge fold are sunken toward the inside of the upper shell to form a groove, and the edge fold is embedded in the groove to form an overlap part. The gas meter solves the problem that metering of the gas meter is attacked through the gap of the contact surface of the adnexal shell and the upper shell, and realizes gas-theft preventing function of the gas meter; moreover, the gas meter has the advantages of simple structure and good anti-theft performance, the prior manufacturing technique maintenance, and easy manufacture, thereby facilitating the quality improvement of manufacturers and reducing the cost.
Description
Technical field
The utility model relates to a kind of gas meter, flow meter of mechanical mechanism, specifically is a kind of anti-theft gaseous gas meter, flow meter.
Background technology
Diaphragm gas meter is a kind of gas meter, flow meter of physical construction, and along with the development of society, people constantly improve it and improve, but the theftproof performance that should show is relatively poor, is each manufacturer and gas company urgent problem always; Though it is antitheft that the method that has has solved, can not solve Welding Problems, the increase cost is not stinted by the producer that therefore has, and increases accessory and operation and solves.
The upper shell of gas meter, flow meter and attached housing are that the mode by spot welding is connected, this mode work efficiency height, and cost is low, good reliability.Because therefore upper shell and attached housing, can not guarantee that the mating surface of two parts is definitely smooth, has the slit between them all by punching stretch forming.
The driving hole of the attached housing of common gas meter, flow meter does not have flange, is a plane, and also not indentation is a plane around the magnet steel hole of upper shell; After both cooperate, with thin metal by slit directtissima gear train easily just.The metrical information of gas meter movement is delivered to magnetic core (magnetic core and gear train transmit by magnetic field) by gear train, and magnetic core and driving gear are rigidly connected, and follower gear and counter are rigidly connected; Transmission by main driven gear is reflected in metrical information on the counter, and as the data of concluding the business.In order to realize stealing gas, general most convenient and least detectable way are attacked above-mentioned part exactly.
Gas meter, flow meter is to have been encapsulated by the movement of metal shell with metering, and the structure of metering is delivered on the counter by gear train, obtains the quantity that combustion gas is used.Therefore the movement of gas meter, flow meter is to be not easy under attackly, but the gear train sum counter externally, is subjected to artificial attack easily, thereby destroy the normal metering of gas meter, flow meter, realizes stealing gas.
Attacking gear train the simplest and easy of gas meter, flow meter and not allowing detectable way is exactly by the upper shell of gas meter, flow meter and the slit between the attached housing, with hard and thin metal, pass the slit up to gear train, even driving gear or follower gear, make the said mechanism can't operate as normal.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective, and a kind of simple in structure, anti-theft gaseous gas meter, flow meter that theftproof performance is good is provided.
For achieving the above object, the technical scheme that is adopted is: a kind of anti-theft gaseous gas meter, flow meter, comprise upper shell, lower house, the counter cover that is welded in the attached housing on the upper shell and is fixed in attached hull outside, one side of described upper shell offers the magnet steel hole, attached housing offers and the corresponding driving hole in magnet steel hole, magnet steel is riveted on the magnet steel hole of upper shell, place the gear train in the upper shell to pass motion to magnetic core by magnetic field, magnetic core is rigidly connected with placing the driving gear in the attached housing, with the follower gear of driving gear engagement with place the counter in the counter cover to be rigidly connected, the slit that exists between described attached housing and the upper shell surface of contact welds together, junction between counter cover and the attached housing is provided with a lead sealing at least, driving hole on the described attached housing forms a flanging to upper shell one rollover folding, described flanging was embedded in to cooperate in this groove and constituted a lap along being recessed to form a groove with the corresponding housing wall of this flanging enclosure interior that makes progress the magnet steel hole of upper shell week.
The length of described attached housing upper hem is less than the degree of depth of upper shell upper groove.The certain angle of formation between the plane, magnet steel hole of attached housing upper hem and upper shell, described angle are 0 °＜angle＜180 °.The plane contact that has guaranteed attached housing plane and upper shell is good, makes both spot welding respond well, not can because of both contact bad when making spot welding electric current puncture upper shell, cause gas meter, flow meter gas leakage or form potential safety hazard.
The utility model has thoroughly solved the problem of attacking the gas meter, flow meter metering by the slit of attached housing and upper shell surface of contact, realized the anti-theft gaseous function of gas meter, flow meter, it is simple in structure, theftproof performance is good, keep original production technology constant, easily manufacture, be beneficial to manufacturer and improve quality, reduce cost.
