Description
Technical field
The utility model relates to a kind of measure that prevents bolt, nut or pin unauthorized intervention, particularly a kind of antitheft securing means.
Background technique
In the prior art, the fastening piece (for example screw, bolt) with screw thread is extensively used as fastening connection piece in fields such as traffic, chemical industry, machineries.For example: being fastenedly connected of being fastenedly connected of automotive oil tank technology flap, car plate, the line of electric force tower advance or being fastenedly connected or the like of outbound port needs to adopt special fastening means prevent that the various device property is stolen.But because above-mentioned securing means only need adopt common tool just can arbitrarily be disassembled at short notice, anti-theft feature is poor.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of antitheft securing means of making equipment stolen of being difficult for is provided.
The purpose of this utility model can realize through following scheme.
Antitheft securing means, comprise threaded fastener, its structure outline is, also comprises a kind of fastening seat and a kind of antitheft plug of inner hollow, the one port embedding of fastening seat contain the threaded fastener termination and by threaded fastener with have case member to be fastenedly connected, antitheft plug is fixed in the another port of fastening seat.
Above-mentioned protected object in the case member is arranged can be the various device property, or anti-theft opening apparatus relevant with the various device property, switch, terminal box or the like need prevent stolen object.
Threaded fastener is threaded connectors such as a kind of screw, bolt, double-screw bolt, nut.
Like this; compare the fastening means that directly fastener threads is connected on the case member housing; the utility model is because of the embedding of threaded fastener termination being contained in fastening seat core and by threaded fastener fastening seat being fastenedly connected in having on the case member; and threaded fastener is blocked by antitheft plug; then if the protected object of usurping in the case member by the dismounting threaded fastener needs to destroy earlier fastening seat or antitheft plug; because fastening seat is by threaded fastener and have the housing of case member to be fastenedly connected; so the behavior of usurping is difficult to carry out, so antitheft effectiveness is strong.
And then with the existing antitheft type fastening screw (ZL03236926.3 that tears open, January 14 2004 day for announcing) compare, the utility model also has unexpected effect, promptly has disguise at the link position that the threaded fastener on the case member is arranged, be difficult for being found, and then just can not dismantled arbitrarily by the robber; And the utility model really need opened advancing or during outbound port, can not destroying the screw threads for fastening structure of case member, thereby practical.
The utility model can be according to the known size of existing threaded connector and the fastening seat and the antitheft plug of series matching corresponding size have supporting with it fastening seat and antitheft plug with convenient different threaded connector.
Further be
Antitheft plug is with the affixed mode of fastening seat or for drive fit is connected, or is to weld.
Also be
Antitheft plug is a kind of cone plug, and antitheft plug is identical with fastening seat inner chamber tapering.
Antitheft plug with fastening seat the upper-end surface after affixed lower than the upper-end surface of fastening seat, or flush with the upper-end surface of fastening seat.
Like this, antitheft plug is difficult for being adopted the mode of gripping to destroy in short-term by the robber.
The purpose of this utility model also can realize through following scheme.
Also comprise a kind of cover body, fastening seat and the welding of cover body outer circumferential face, or fastening seat and cover body integrally casting.
Like this, not very firm equipment when relating to for example deciphering this external casings such as final controlling element or switch with this antitheft fastener application, then can adopt these equipment sealing covers are gone in the cover body to protect.
At this moment, the quantity with the affixed fastening seat of cover body is at least two.
Described fastening seat is a kind of steel seat.
Antitheft plug is a kind of steel plug.
Cover body is a kind of steel cage.
Certainly adopt other firm material can also make this fastening seat, antitheft plug and cover body.
In sum, the utility model has following advantage compared to prior art: the behavior of usurping that makes the robber dismantle threaded fastener is difficult to carry out, and is found easily, antitheft effectiveness is strong, and has disguise, is difficult for being found by the robber, can not destroy the screw threads for fastening structure, install and implement conveniently, practical.
