Abstract
The utility model discloses a kind of theftproof joint, including nut and tamper housing；The tamper housing includes the housing split of two semi-annular shapes, and the both ends of the housing split are equipped with lug, is axially arranged with mounting hole along housing split on the lug；The two sides splicing that the housing split is placed on the nut forms circular tamper housing；Pass through fixed pin locked between the lug of housing split described in two.The connector can play antitheft effect, while can also be utilized again.
Description
Technical field
The utility model is related to technical fields such as tap water meter, gas meter, flow meters, more particularly to a kind of theftproof joint.
Background technology
The meter connector that every profession and trade generally uses at present, nut and fittings body connect one complete meter connector of composition.This
Kind structure has any shortcoming, and the meter connector of this structure can be dismounted arbitrarily, particularly gas meter, flow meter field, arbitrarily dismounts or arrogates to oneself
From dismounting meter connector, gas, gas leakage and the table violating the regulations stolen is triggered to have damage.Patent No. 200520132680.9 discloses one
The disposable theftproof joint of kind, the meter connector connect into complete meter connector by housing and nut and fittings body.Under the housing
Portion end is a circular groove, and housing inner sleeve nut, nut lower end outer is a circular groove, put in circular groove different in nature retainer ring by nut and
Housing is stuck.The structure can achieve the purpose that prevention arbitrarily or dismount without authorization, solve gas industry because arbitrarily or without authorization
Gas, leakage and table tool damage are stolen caused by dismounting meter connector.But it is such to be designed as disposable structure, it is needed when dismantling nut
Housing is caught broken, causes the waste of material, and intermediate bellows is also eliminated.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of theftproof joint, which can play antitheft effect,
It can also be utilized again simultaneously.
The technical solution of the utility model is to provide a kind of theftproof joint having following structure, including nut and
Tamper housing；The tamper housing includes the housing split of two semi-annular shapes, and the both ends of the housing split are equipped with
Lug is axially arranged with mounting hole on the lug along housing split；The housing split is placed on the both sides of the nut
It is spliced to form circular tamper housing；Pass through fixed pin locked between the lug of housing split described in two.
After more than structure, the theftproof joint of the utility model compared with prior art, has the following advantages：
Since the tamper housing of the theftproof joint of the utility model includes the housing split of two semi-annular shapes, described in two
Housing split lug between by fixed pin locked, antitheft effect can be played by tamper housing, during dismounting, as long as logical
Can just fixed pin be removed by crossing specific purpose tool, will not damage tamper housing, which can reuse.
As an improvement, the outer surface of the nut is equipped with annular recess, the inner wall of the housing split is equipped with
Protrusion, the protrusion are stretched into the groove.After adopting the structure, tamper housing rotation will not drive spiral shell
Mother's rotation can effectively act as the effect of tamper.
As an improvement, the mounting hole is stepped hole, after two housing split splicings, the spliced shape of mounting hole is
The structure of big at both ends and small in middle.Simple in structure after adopting the structure, tamper effect is preferable.
As an improvement, the fixed pin includes plunger and pin rod, the plunger is connected to one end of the pin rod,
The pin rod is axially arranged with cross crotch along it, and the other end of the pin rod is equipped with barb.After adopting the structure, structure letter
Single, tamper effect is preferable.

Specific embodiment
It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in Figures 1 to 8, the theftproof joint of the utility model includes nut 1 and tamper housing 2；Outside the tamper
Set 2 includes the housing split 201 of two semi-annular shapes, and the both ends of the housing split 201 are equipped with lug 202, described
It is axially arranged with mounting hole 203 along housing split 201 on lug 202；The housing split 201 is placed on the two of the nut 1
Side is spliced to form circular tamper housing 2；It is locked between the lug 202 of housing split 201 described in two by fixed pin 3.
The outer surface of the nut 1 is equipped with annular recess 101, and the inner wall of the housing split 201 is equipped with convex
204 are played, the protrusion 204 is stretched into the groove 101.
The mounting hole 203 is stepped hole, and after two housing splits 201 are spliced, 203 spliced shape of mounting hole is
The structure of big at both ends and small in middle.The fixed pin 3 includes plunger 301 and pin rod 302, and the plunger 301 is connected to described
Pin rod 302 one end, the pin rod 302 is axially arranged with cross crotch 303 along it, and the other end of the pin rod 302 is equipped with
Barb 304.
The theftproof joint assembling process of the utility model is as follows：Nut 1 is attached with gas meter, flow meter or tap water meter,
Then two housing splits 201 are respectively sleeved in the both sides of nut 1, led between the lug 202 of housing split 201 and lug 202
The fixed pin 3 is crossed to be fixedly connected.
