Abstract
The utility model discloses an antitheft connector of gas meter belongs to the instrument field, including the connecting pipe and with one of which end screw thread connection's nut, the one end of connecting pipe is provided with the external screw thread, and the other end is provided with the sealing washer, uniformly spaced counter sink has been seted up to nut circumference on the surface, set up the type type hole that is located the counter sink below on the connecting pipe, and the downthehole lower extreme of type is provided with the inflation cover, be provided with the bolt in the counter sink on the nut, and the lower extreme of bolt is located the inflation cover. The utility model discloses make the nut more firm with being connected of connecting pipe, effectual nut and the connecting pipe avoided drops, also can effectually prevent revealing and stealing of gas simultaneously.
Description
Technical field
The utility model belongs to instrument field, in particular to a kind of theftproof joint of gas meter, flow meter.
Background technology
The effect of usual gas meter connector by nut, connecting pipe and gas meter, flow meter is coupled together, but it is quick detachable to be threaded, and gas leakage and theft phenomenon often can occur, bring serious loss, also threatened the life security of resident simultaneously to air feed enterprise.
Utility model content
The purpose of this utility model is the theftproof joint providing a kind of gas meter, flow meter, to solve the problem.
For realizing the utility model object, the technical scheme adopted is: a kind of theftproof joint of gas meter, flow meter, the nut comprising connecting pipe and be threaded with its one end, one end of described connecting pipe is provided with external thread, the other end is provided with O-ring seal, and in described nut surface, circumference offers evenly spaced counter sink; Described connecting pipe offers the type nibs be positioned at below counter sink, and the lower end in type nibs is provided with expansion sleeve; Be provided with bolt in counter sink on described nut, and the lower end of bolt is positioned at expansion sleeve.
Further, the counter sink on described nut is at least 3.
The beneficial effects of the utility model are, first by nut, connecting pipe is tightened, now on nut, offer counter sink, connecting pipe offers the type nibs be positioned at below counter sink, and the lower end in type nibs is provided with expansion sleeve, now bolt is arranged in the counter sink of nut, and the lower end of bolt is fixedly fastened in expansion sleeve, make expansion sleeve together with being bolted to, due to the expansion of expansion sleeve, therefore the connection of nut and connecting pipe is more firm, nut and connecting pipe is effectively avoided to come off, also effectively can prevent leakage and the theft of combustion gas simultaneously.
Accompanying drawing explanation
Fig. 1 is the cut-open view of the theftproof joint of the gas meter, flow meter that the utility model provides;
Fig. 2 is the partial enlarged drawing of part A in Fig. 1;
Mark and corresponding parts title in accompanying drawing:
1, connecting pipe, 11, type nibs, 111, expansion sleeve, 2, nut, 21 counter sinks, 3, O-ring seal, 5, expansion bolt, 7, bolt.
Embodiment
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1, Fig. 2 show the theftproof joint of the gas meter, flow meter that the utility model provides, the nut 2 comprising connecting pipe 1 and be threaded with its one end, one end of described connecting pipe 1 is provided with external thread, and the other end is provided with O-ring seal 3, and described nut 2 on the surface circumference offers evenly spaced counter sink 21; Described connecting pipe 1 offers the type nibs 11 be positioned at below counter sink 21, and the lower end in type nibs 11 is provided with expansion sleeve 111; Bolt 7 is provided with in counter sink 21 on described nut 2, and the lower end of bolt 7 is positioned at expansion sleeve 111, now the lower end of bolt 7 is fixedly fastened in expansion sleeve 111, expansion sleeve 111 and bolt 7 are fixed together, due to the expansion of expansion sleeve 111, what therefore nut 2 was connected with connecting pipe 1 is more firm, effectively avoids nut 2 and connecting pipe 1 to come off, also effectively can prevent leakage and the theft of combustion gas simultaneously.Counter sink 21 on described nut 2 is at least 3, and the distribution of counter sink 21 is more even, makes nut 2 more firm with the connection of connecting pipe 1.
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.
