Abstract
The utility model discloses a dismounting preventing gas meter connector. The connector comprises a connecting tube and a screw cap, wherein the screw cap can be rotationally connected with the lower end of the connecting tube; a sealing ring is arranged on the lower end surface of the connecting tube; external threads are arranged at the upper end of the connecting tube; the screw cap comprises an outer sleeve and an inner sleeve; the outer sleeve is sleeved outside the inner sleeve; internal threads are arranged on the cavity of the inner sleeve; an annular groove is formed in the outer peripheral wall of the inner sleeve; a plurality of insertion slots are uniformly distributed in the outer peripheral wall of the inner sleeve positioned in the annular groove; a plurality of inclined plane grooves are uniformly distributed in the inner peripheral wall of the outer sleeve; an elastic steel disc which is bent into a right angle is inserted into each insertion slot; the other end of the elastic steel disc is propped against the interior of the inclined plane groove; a first annular clamping groove is formed at the lower part of the outer peripheral wall of the inner sleeve; a clamping spring is clamped in the first annular clamping groove; a second annular clamping groove corresponding to the first annular clamping groove is formed at the lower part of the inner peripheral wall of the outer sleeve; the clamping spring is also positioned in the second annular clamping groove. The connector can effectively prevent the phenomenon that people casually dismount the screw cap on the connecting tube to cause gas leakage and gas stealing.
Description
Technical field:
The utility model relates to a kind of joint, is specifically a kind of anti-demolition diaphragm gas meter connector.
Background technology:
At present, gas meter connector all comprises a connecting pipe conventionally, nut of the rotating connection in connecting pipe lower end, by the internal thread on nut, connecting pipe is tightened on gas meter, flow meter, above this structure can be random by general spanner dismounting nut, the generation ，Gei air feed enterprise of usually causing leakage combustion gas and theft combustion gas phenomenon brings loss.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of and can effectively prevent that people from arbitrarily dismantling the caused leakage combustion gas of nut and the anti-demolition diaphragm gas meter connector of stealing combustion gas phenomenon on connecting pipe.
Technical solution of the present utility model is, a kind of anti-demolition diaphragm gas meter connector with following structure is provided, comprise connecting pipe and nut, the rotating lower end that is connected to connecting pipe of nut, the lower surface of connecting pipe is provided with O-ring seal, the upper end of connecting pipe is provided with external thread, wherein, nut comprises jacket and inner sleeve, overcoat is enclosed within the outside of inner sleeve, the inner chamber of inner sleeve is provided with internal thread, the periphery wall of inner sleeve is provided with annular groove, be positioned on the periphery wall of inner sleeve of annular groove and be evenly equipped with a plurality of slots, on the internal perisporium of overcoat, be evenly equipped with a plurality of inclined plane grooves corresponding with slot, the degree of depth of each inclined plane groove all reduces gradually along the direction that screws of internal thread, in each slot, be all inserted with a rectangular elastic steel sheet of bending, the other end of elastic steel sheet withstands in inclined plane groove, the periphery wall bottom of inner sleeve is provided with the first annular slot, in the first annular slot, card has jump ring, the internal perisporium bottom of overcoat is provided with second annular slot corresponding with the first annular slot, jump ring is positioned at the second annular slot simultaneously.
Adopt after above structure, compared with prior art, the utility model anti-demolition diaphragm gas meter connector has the following advantages: when connecting pipe being tightened on gas meter, flow meter by nut, rotary sleeve, by elastic steel sheet, can drive inner sleeve to be tightened on gas meter, flow meter, when contrary direction is again during rotary sleeve, Elastic Steel sector-meeting produces in the inclined plane groove that is out of shape and puts from outward and skids off, thereby can not drive inner sleeve to rotate, in other words, by the nut overcoat rotating on the utility model anti-demolition diaphragm gas meter connector, only connecting pipe is tightened on gas meter, flow meter, and can not again connecting pipe be spun down from gas meter, flow meter, therefore, the utility model anti-demolition diaphragm gas meter connector can effectively prevent that people from arbitrarily dismantling the caused leakage combustion gas of nut on connecting pipe and stealing the phenomenon of combustion gas.
Accompanying drawing explanation:
Fig. 1 is that the master of the utility model anti-demolition diaphragm gas meter connector looks sectional structure schematic diagram;
Fig. 2 is the exploded structural representation of inner sleeve and elastic steel sheet in the utility model anti-demolition diaphragm gas meter connector;
