Abstract

The utility model discloses a joint of gas table, including the connecting pipe, rather than threaded connection's nut, the nut is located to have seted up a plurality of spouts with connecting pipe screw -thread fit, and the nut is fixedly connected with elasticity toper lug in the spout, the outer disc that the connecting pipe stretched into the tip in the nut is equipped with the annular arch, the spout of connecting pipe nut after the installation corresponds the position and is equipped with the fixed slot, is equipped with the rectangle piece in the fixed slot, and the rectangle piece cooperatees with the fixed slot of the spout of nut and connecting pipe respectively and is connected, and the end of rectangle piece is equipped with the arch, and the arch is blocked and is established between elasticity toper lug and annular arch, the ring channel has been offered to the bellied outer disc of annular, is equipped with the sealing ring in the ring channel, and the sealing ring matches with the nut inner wall. This joint of gas table theftproof nature is good, prevents effectively that the private from tearing the gas table open, avoids the potential safety hazard.

Description

A kind of joint of gas meter, flow meter
Technical field
The utility model relates to instrument field, in particular to a kind of 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 joint providing a kind of gas meter, flow meter, to solve the deficiencies in the prior art.
For realizing the utility model object, the technical scheme of employing is:
A joint for gas meter, flow meter, comprises connecting pipe, and the nut be threaded with it, is characterized in that, described nut and connecting pipe threaded engagement place offer multiple chute, and nut is connected with elastic cone projection at chute internal fixtion; The periphery of the end that described connecting pipe stretches in nut is provided with annular protrusion; The chute correspondence position of described connecting pipe nut is after mounting provided with pickup groove, rectangular block is provided with in pickup groove, rectangular block respectively with the chute of nut and the pickup groove of connecting pipe in mating connection, the end of rectangular block is provided with projection, and projection is fastened between elastic cone projection and annular protrusion; The periphery of described annular protrusion offers ring groove, is provided with sealing ring in ring groove, and sealing ring matches with nut inwall.
Further, multiple chute distributes along nut even circumferential.
The beneficial effects of the utility model are,
By being provided with rectangular block at the threaded engagement place of nut and connecting pipe, nut or connecting pipe cannot be rotated respectively, make both be separated, the projection of rectangular block is fastened between elastic cone projection and annular protrusion simultaneously, effectively avoid manually rectangular block being extracted out, realize dismounting nut and connecting pipe.This gas meter connector anti-theft is good, effectively prevents private from tearing gas meter, flow meter open, avoids potential safety hazard.
Accompanying drawing explanation
Fig. 1 is the structural representation of the joint of the gas meter, flow meter that the utility model provides;
Fig. 2 is the structure for amplifying schematic diagram of B.
Embodiment
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
The joint of Fig. 1-2 is shown a kind of gas meter, flow meter that the utility model provides, comprising: connecting pipe 1, nut 2, chute 3, rectangular block 5, sealing ring 6, elastic cone projection, projection and annular protrusion 4.Described connecting pipe 1 is threaded with nut 2; Described nut 2 offers multiple chute 3 with connecting pipe 1 threaded engagement place, and nut 2 is connected with elastic cone projection 7 at chute 3 internal fixtion; The periphery of the end that described connecting pipe 1 stretches in nut 2 is provided with annular protrusion 4; Chute 3 correspondence position of described connecting pipe 1 nut 2 is after mounting provided with pickup groove, rectangular block 5 is provided with in pickup groove, rectangular block 5 respectively with the chute 3 of nut 2 and the pickup groove of connecting pipe 1 in mating connection, the end of rectangular block 5 is provided with projection, and projection is fastened between elastic cone projection 7 and annular protrusion 4; The periphery of described annular protrusion 4 offers ring groove, is provided with sealing ring 6 in ring groove, and sealing ring 6 matches with nut 2 inwall.Multiple chute 3 distributes along nut 2 even circumferential.
By being provided with rectangular block 5 at nut 2 and the threaded engagement place of connecting pipe 1, nut 2 or connecting pipe 1 cannot be rotated respectively, make both be separated, the projection of rectangular block 5 is fastened between elastic cone projection 7 and annular protrusion 4 simultaneously, effectively avoid manually rectangular block 5 being extracted out, realize dismounting nut 2 and connecting pipe 1.This gas meter connector anti-theft is good, effectively prevents private from tearing gas meter, flow meter open, avoids potential safety hazard.
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.
