Description
Technical field
The utility model relates to a kind of anti-theft meter connecting pipe, belongs to technical field of pipeline connection.
Background technique
At present, the nut major part that gas meter connects is ordinary couplings, and is directly exposed to the external world, and people adopt conventional instrument both can butt joint to carry out tightening or unclamping, and is easy to, by the dismounting of people's malice, increase potential safety hazard to safe gas.
Summary of the invention
For solving the problem, the utility model provides a kind of structure simple, anti-theft meter connecting pipe easy to use.
The technological scheme that the utility model adopts for its problem of solution is:
A kind of anti-theft meter connecting pipe, comprise joint, flange and connect the corrugated flexible hose of described joint and flange, described flange outer sleeve is equipped with one-way rotation nut body; Described one-way rotation nut body comprises overcoat and is inlaid in described overcoat, free to rotate inner sleeve nut; On the wall of described overcoat, radially direction is provided with mounting hole, and the outer wall of described inner sleeve nut is provided with the groove corresponding with described mounting hole; Be slidably fitted with the slide block that can snap in or depart from described groove in described mounting hole, the end described slide block being positioned at described groove side is provided with towards the inclined-plane of inner sleeve nut rotational direction.
Preferably, the bottom on described inclined-plane and the perpendicular distance at its top are greater than the degree of depth of described groove.
Preferably, described one-way rotation nut body also comprises and is positioned at described mounting hole, makes described slide block keep snapping in the elastic component of described groove.
Preferably, described mounting hole is through hole, and the external port of mounting hole is provided with the sprue of blocking mounting hole.
Preferably, the outer surface of described flange is provided with a circle boss, the end face of described overcoat is provided with the circle lip part be connected on described boss.
Further, described inner sleeve nut is connected to the inner side of described lip part.
Further, the end described flange being positioned at inner sleeve nut interior is provided with seal washer.
Preferably, described one-way rotation nut body is provided with multiple, and the axle center of winding orchid is evenly arranged.
Preferably, the cross section of described mounting hole and groove is polygonal.
Preferably, described overcoat is regular polygon.
The beneficial effects of the utility model are: the utility model structure is simple, easy to use, and when overcoat rotates to the direction of inner sleeve nut screwing clamping, slide block is connected between mounting hole and groove, thus makes overcoat drive inner sleeve nut to rotate together, and inner sleeve nut is tightened.When overcoat rotates to the direction that inner sleeve nut is unscrewed, the inclined-plane of slide block abuts with the port of groove, the port of groove moves along slope driving slide block to overcoat side, until slide block leaves groove completely, overcoat is lost the active force to inner sleeve nut, cannot drive inner sleeve nut rotation, inner sleeve nut cannot be unscrewed, thus reaches antitheft object.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is internal structure schematic diagram of the present utility model;
Fig. 2 is the front section view of one-way rotation nut body of the present utility model;
Fig. 3 is the side sectional view of one-way rotation nut body of the present utility model.
In figure: 1, joint; 2, flange; 3, corrugated flexible hose; 4, overcoat; 5, inner sleeve nut; 6, mounting hole; 7, groove; 8, slide block; 9, inclined-plane; 10, elastic component; 11, sprue; 12, boss; 13, lip part; 14, seal washer.
Embodiment
A kind of anti-theft meter connecting pipe as shown in accompanying drawing 1 to 3, comprise joint 1, flange 2 and connect the corrugated flexible hose 3 of described joint 1 and flange 2, corrugated flexible hose 3 outer ring is provided with protecting cover protection.One-way rotation nut body is set with outside described flange 2.Described one-way rotation nut body comprises overcoat 4 and is inlaid in described overcoat 4, free to rotate inner sleeve nut 5, and described overcoat 4 can be regular polygon, and spanner easy to use tightens overcoat 4 and inner sleeve nut 5.On the wall of described overcoat 4, radially direction is provided with mounting hole 6, and the outer wall of described inner sleeve nut 5 is provided with the groove 7 corresponding with described mounting hole 6; Be slidably fitted with the slide block 8 that can snap in or depart from described groove 7 in described mounting hole 6, the end described slide block 8 being positioned at described groove 7 side is provided with towards the inclined-plane 9 of inner sleeve nut 5 rotational direction.
When overcoat 4 rotates to the direction that inner sleeve nut 5 is tightened, slide block 8 is connected between mounting hole 6 and groove 7, thus makes overcoat 4 drive inner sleeve nut 5 to rotate together, and inner sleeve nut 5 is tightened.When overcoat 4 rotates to the direction that inner sleeve nut 5 is unscrewed, the inclined-plane 9 of slide block 8 abuts with the port of groove 7, the port of groove 7 promotes slide block 8 and moves to overcoat 4 side along inclined-plane 9, until slide block 8 leaves groove 7 completely, overcoat 4 is lost the active force to inner sleeve nut 5, inner sleeve nut 5 cannot be driven to rotate, and inner sleeve nut 5 cannot be unscrewed, thus reaches antitheft object.
The described bottom on inclined-plane 9 and the perpendicular distance at its top are greater than the degree of depth of described groove 7, and the port of groove 7 can contact with inclined-plane 9, to make slide block 8 can be promoted by the port of groove 7, and then to mounting hole 6 one Slideslip.Certainly, can also abut with the top on inclined-plane 9 by the raised structures arranged higher than bottom surface in the bottom of groove 7, the bottom on inclined-plane 9 is stretched out from the port of groove 7.
Described one-way rotation nut body also comprises and is positioned at described mounting hole 6, makes described slide block 8 keep snapping in the elastic component 10 of described groove 7.When overcoat 4 rotates along the direction that inner sleeve nut 5 is tightened, slide block 8 is connected to all the time between mounting blocks and groove 7 under the active force of elastic component 10.
Described mounting hole 6 is through hole, the external port of mounting hole 6 is provided with the sprue 11 of blocking mounting hole 6, and sprue 11 can be fixed on the external port of mounting hole 6 by welding or bonding mode, when needs make overcoat 4 and inner sleeve nut 5 separates, sprue 11 can be destroyed, slide block 8 is taken out.
The outer surface of described flange 2 is provided with a circle boss 12, the end face of described overcoat 4 is provided with the circle lip part 13 be connected on described boss 12, described inner sleeve nut 5 is connected to the inner side of described lip part 13, prevents flange 2 and inner sleeve nut 5 from deviating from from one end of overcoat 4.The end described flange 2 being positioned at inner sleeve nut 5 inside is provided with seal washer 14, prevents gas from going out from the slot leakage between inner sleeve nut 5 and flange 2.
Described one-way rotation nut body is preferably provided with multiple, and the axle center of winding orchid 2 is evenly arranged, and to increase the tangential forces between overcoat 4 and inner sleeve nut 5, and can ensure mechanism's uniform force.
Described mounting hole 6 is polygonal with the cross section of groove 7, and the cross section of slide block 8 is also consistent with mounting blocks, groove 7, and anti-limited slip block 8 rotates in mounting blocks, and then inclined-plane 9 is shifted, and affects the regular event of mechanism.Certainly, guiding groove or guide protrusions can also be set respectively in mounting blocks, groove 7 and on slide block 8.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
