Abstract
The utility model relates to an interface anti-theft connecting device of water and gas gauge tables, which comprises a mobile connecting body and a screw cap, wherein one end of the mobile connecting body is provided with a screw to be connected with the screw cap, and the other end of the mobile connecting body is provided with a flange, the lateral surface of the screw cap is provided with at least a boss, a positioning pin inserting hole which is extended into the mobile connecting body is arranged in the boss, a positioning pin is mounted in the positioning pin inserting hole, and the mobile connecting body is provided with at least two positioning pin non-return teeth, a bushing counterbore is arranged on the orifice of the positioning pin inserting hole, a bushing is arranged in the bushing counterbore, and a spring is arranged between a positioning pin and a bushing. The utility model has the advantages of simple structure, convenient implementation and excellent anti-theft effect, which can not be detached by a user under the circumstance without damaging a connecting screw cap of a screw-connected hole of a gauge table.
Description
Technical field
The utility model relates to gas, level meter scale interface link, particularly a kind of water, the antitheft coupling arrangement of gas measurement table interface.
Background technology
The gauging table of existing piped gas, rock gas or water is to receive in the pipeline by the mouth that is spirally connected, and its mouth that is spirally connected is connected with pipeline by a nut and one section screw nipple.Because of there not being reliable anti-theft measure, gauging table is easy to be disassembled privately by the certain user, or the rotating speed that will show of taking an improper hand slows down, reach theft and use the purpose of coal gas, rock gas or water, this situation often is difficult for being found by the staff of air feed, water supply department, not only cause very big economic loss, also exist potential safety hazard simultaneously to administrative authority.For solving the problem of this respect, have plenty of the making stealingproof sleeve, gauging table is closed; The employing line lead sealing that has connects together nut and the pipeline that gauging table is spirally connected on the mouth, rotates to prevent nut.But above antitheft mode or cost are too high, and certain difficulty perhaps is installed, and the user is difficult to accept, and perhaps juggle things easily and do not stay sharp trace, do not reach antitheft purpose.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of water, the antitheft coupling arrangement of gas measurement table interface, and is simple in structure, and it is convenient to implement, and good anti-theft effect makes the user be spirally connected under the situation of mouthful coupling nut not destroying gauging table, can't dismantle.
For solving above-mentioned prior art problems, the utility model adopts following scheme: a kind of water, the antitheft coupling arrangement of gas measurement table interface, comprise loose joint body and the nut that is threaded with the loose joint body, described pane is provided with at least one boss, be provided with the register pin jack that feeds the loose joint body in the boss, in the register pin jack register pin is housed, at least offer two register pin stoppers on the loose joint body, described register pin jack aperture is provided with edge cover counterbore, be provided with the edge cover in the edge cover counterbore, be provided with spring between described register pin and the edge cover.
As preferably, the end that described loose joint body is provided with screw thread is provided with sealing gasket.Prevent to leak.
As preferably, described boss is one.
As preferably, described register pin stopper is four that uniform ring is established.
The utility model is owing to adopt technique scheme, when installing with gauging table, it is the same installing with articulation with common nut, when nut and gauging table approximately are connected to two teeth, anti-theft feature just begins to work, and nut can only screw and can not unscrew this moment, under gravity and spring force effect, the register pin leading portion enters in the stopper, the nut anglec of rotation≤180 °.The user is spirally connected under the situation of mouthful coupling nut not destroying gauging table, can't dismantle gauging table, has reached antitheft purpose.It is simple in structure, and cost is lower, is convenient to implement.

Embodiment
As Fig. 1 to Fig. 4, a kind of water, the antitheft coupling arrangement of gas measurement table interface, comprise loose joint body 1 and nut 2, described loose joint body 1 one ends are provided with screw thread and are connected with nut 2, loose joint body 1 other end is provided with flange, described nut 2 sides are provided with a boss 3, be provided with the register pin jack 4 that feeds loose joint body 1 in the boss 3, register pin 5 is housed in the register pin jack 4, uniform ring is provided with four register pin stoppers 6 on the loose joint body 1, described register pin jack 4 apertures are provided with edge cover counterbore 7, are provided with edge cover 8 in the edge cover counterbore 7, are provided with spring 9 between described register pin 4 and the edge cover 8.Described edge cover 8 can adopt rivet tightly, reducing or other glue is fixed in the edge cover counterbore 7, prevents that register pin 5 from dropping out.The end that described loose joint body 1 is provided with screw thread is provided with sealing gasket 10.Prevent to leak.
Can earlier register pin 5 and spring 9 be put in the register pin jack 4 of nut 2 before dispatching from the factory, will inlay cover 8 and arrive in the edge cover counterbore 7 by riveted and fixed.During installation, general as long as be spirally connected in the air inlet of gauging table this coupling arrangement mouthful is installed, mouthful common nut can be installed and the loose joint body get final product and give vent to anger to be spirally connected at the gas measurement table, certain two ends are installed this product simultaneously and can be reached better effect.The inlet, outlet of gas measurement table are spirally connected mouthful operated by rotary motion on its end face, during installation, the thread segment of loose joint body 1 is passed from nut 2 and connect with pipeline, and the flange face of loose joint body 1 is aimed at the gas measurement table mouth that is spirally connected, and nut 2 are tightened get final product.Under spring 9 elastic force effects, register pin 5 leading portions fall on the loose joint body 1 in the register pin stopper 6, make nut 2 anglecs of rotation less than 180 °, and like this, the user is spirally connected under the situation of mouthful coupling nut 2 not destroying gauging table, just can't dismantle.Even after installing, register pin 5 leading portions fail to fall into just in the register pin stopper 6 on the loose joint body 1, as long as the user is a little during rotating screw cap 2 certain angles, register pin 4 hypomeres just can fall in the register pin stopper 6 in spring 5 elastic force effects, realize the non-dismountable of nut, reached antitheft purpose.It is antitheft that the technical solution of the utility model not only can be used for the gauging table of coal gas, rock gas or water, also can be used for the antitheft of other gases such as heating installation, level meter scale.
