Abstract
An antitheft connecting fastener comprises a bolt, a nut and a socket wrench for fastening, and is characterized by also comprising a pair of pads between the bolt and the nut and a sheath which is sleeved on the pads and has a waterproof cover. The sheath is a cylindrical structure body, which is provided with threads at one end and with a circular baffle plate at the other end. One side of the pads is equipped with a circular boss, the diameter of which is smaller than the inner diameter of the baffle plate. The diameter of the pads is larger than the inner diameter of the baffle plate. One side of the waterproof cover is in threaded connection with the sheath, and the other side is provided with a boss. The socket wrench consists of a socket and a handle fixedly connected on the socket. The socket is a tubular structure body in coincidence with the nut or the bolt in shape. The antitheft connecting fastener of the utility model, which has the characteristics of simple structure, novel design, convenient utilization and significant antitheft effect, can be used repeatedly and be widely applied to various engineering environments.
Description
Technical field
The utility model relates to a kind of connection fastening means, is specifically related to a kind of antitheft connection fastening piece.
Background technique
At present, particularly highway limit adequate and systematic service facility, all kinds of environmental monitoring facility, off-shore structure facility etc. are because unattended for many public good equipment, and often to subject to artificial dismounting destroyed because of fastening piece, caused serious economy loss to country.Existing various antitheft connection fastening piece is perhaps processed and is installed complexity and is disposable product, can't dismantle and reuse; Perhaps lack the protection to its bolt head and nut, the robber can touch bolt and nut easily, still can unscrew nut with some common instruments.Existing in a word antitheft connection fastening piece exists and uses inconveniently, and shortcoming such as anti-theft effect is not obvious does not have a kind of simple to operately at present as yet, and anti-theft effect significantly connects fastening piece.
Summary of the invention
The purpose of this utility model provides a kind of simple to operate, antitheft connection fastening piece of outstanding effect, is applied on the unserviced facility to overcome the deficiencies in the prior art.
The utility model comprises screw bolt and nut, and a kind of antitheft connection fastening piece comprises it is characterized in that the socket wrench of bolt, nut and fastening usefulness also comprising a pair of pad between the screw bolt and nut, and be nested with the sheath that has waterproof cover on pad; Described sheath is the threaded tubular structure body of an end, and this tubular structure body the other end has circular baffle plate; Described pad one side has circular boss, and the diameter of boss is less than the inner diameter of above-mentioned baffle plate, and the diameter of pad is greater than the inner diameter of baffle plate; Described waterproof cover one side is threaded with sheath, and opposite side is provided with plush copper.
Consider and be convenient to processing and fabricating and use that the bolt head of bolt and the profile of nut can be processed into identical abnormity, as are processed into nonstandard shapes such as large semi-circular, pentagon, can prevent to utilize conventional instrument to dismantle, and have increased theftproof performance.
The shape of above-mentioned plush copper or pothole is convenient to operation and is got final product, as regular hexagon or square etc.
The special sleeve spanner of this antitheft connection fastening piece is a sleeve and is fixed in handle on this sleeve, described sleeve is the tubular body structure that matches with nut or bolt shape, promptly the shape of cross section of this tubular structure intracoelomic cavity is identical with the shape of nut or bolt head, and the outer diameter of tubular body structure is less than the inner diameter of sheath.
Consider anticorrosion and strengthen protection screw bolt and nut; be processed with screw thread in the outer end of sheath and waterproof cover be installed by screw thread; can in sheath, irritate lubricant grease and get rusty, both can increase attractive in appearancely, can protect nuts and bolt effectively again to prevent bolt or nut.
Above-mentioned pad is tightened because of bolts and nuts and is fixed, be nested with the sheath on the pad can about idle running, thereby external force can't be acted directly on bolt head and the nut, must use special sleeve spanner could dismantle this fastening piece, so sheath has played reliable anti-theft effect.
The utlity model has simple in structure, novel in design, easy to use, characteristics such as anti-theft effect is obvious, it utilizes the sheath that is enclosed within on the pad to solve the antitheft problem of standard fasteners dexterously, has avoided the robber to contact with the effective of bolt and nut, play anti-theft effect significantly, in addition the utility model also solved present part theftproof bolt nut can't reusable shortcoming, have reusable characteristics, and can be widely used in all kinds of engineering-environments.

Embodiment
Shown in Fig. 1～6, the utility model comprises the socket wrench 10 of bolt 7, nut 5 and fastening usefulness, it is characterized in that also comprising a pair of pad 6 between bolt 7 and the nut 5, and is nested with the sheath that has waterproof cover 12 on pad 6; Described sheath 2 is the threaded tubular structure bodies of an end, and this tubular structure body the other end has circular baffle plate 9; Described pad 6 one sides have circular boss 8, and the diameter of boss 8 is less than the inner diameter of above-mentioned baffle plate 9, and the diameter of pad 6 is greater than the inner diameter of baffle plate 9; Described waterproof cover 1 one sides are threaded with sheath 2, and opposite side is provided with plush copper 13.
Shown in Fig. 3,5, consider and be convenient to processing and fabricating and use that the bolt head of bolt 7 can be processed into identical abnormity with the profile of nut 5, as is processed into nonstandard shapes such as large semi-circular, pentagon, can prevent to utilize conventional instrument to dismantle, increase theftproof performance.
As shown in Figure 2, the shape of above-mentioned plush copper 13 or pothole is convenient to operation and is got final product, as regular hexagon or square etc.
As shown in Figure 7, the special sleeve spanner 10 of this antitheft connection fastening piece is a sleeve 11 and is fixed in handle 12 on this sleeve 11, described sleeve 11 is the tubular body structures that match with nut 5 or bolt 7 shapes, promptly the shape of cross section of this tubular structure intracoelomic cavity is identical with the shape of nut 5 or bolt 7 bolt heads, and the outer diameter of tubular body structure is less than the inner diameter of sheath 2 bodies.
As shown in Figure 1, 2, when treating fitting and B, A treats that fitting 4 needs be connected when fastening, at first install pad 6 and sheath 2 successively on bolt 7, and pad 6 has the one side of boss 8 towards A link 3; Pass A link 3 and B link 4 with bolt 7 then; Side at B link 4 is nested with another sheath 2 on the termination of bolt 7 with pad 6 successively, and pad 6 has the one side of boss 8 towards B link 4; Nut 5 is installed at last and is pulled 10 hand-tight admittedly with sleeve, screw in sheath 2 screwed ends with waterproof cover 1 again and promptly finished above two connections for the treatment of fitting fastening.For anticorrosion and strengthen anti-theft effect, can in sheath 2, irritate lubricant grease, can prevent that bolt 7 or nut 5 from getting rusty and be difficult for opening.
When only being connected with nut or bolt when being connected to double-screw bolt with screw---a need protect an end, when the other end need not to protect, also can adopt the utility model.On double-screw bolt, overlap upper jacket 2, pad 6 and nut 5 when double-screw bolt is connected with nut successively, use socket wrench 10 fastening then, in sheath 2, irritate lubricant grease again and cover waterproof cover 1 promptly finished connect fastening.When bolt is connected with screw, earlier on bolt 7, be nested with pad 6 and sheath 2 successively, then bolt 7 be screwed into screw and fastening, sheath 2 in, irritate lubricant grease again and cover waterproof cover 1 that promptly to have finished connection fastening with socket wrench 10.
