Abstract
The utility model relates to an anti -theft fastener, characterized by, including the bolt, the bolt passes to -be -installed object spare, still includes antitheft nut, and the antitheft nut overcoat has the sleeve, a sleeve end position open structure, and open the bottom surface of the other end has the through -hole, and the bolt passes the through -hole, antitheft nut clamp sleeve's in the sleeve bottom surface is fixed the sleeve on to -be -installed object spare. The utility model discloses simple structure, the installation of being convenient for. And lower cost. All unable effective dismouting of instrument such as commonly used spiral shell sword, spanner, pliers, hammer can effectual preventions criminal be dismantled, can ensure own convenient dismantlement simultaneously again, and not detachable drawback is once only assembled in the release.
Description
Technical field：
This utility model is related to a kind of anti-theft fastening piece.
Background technology：
Some objects are out of doors etc. unattended local when installing, and often occur to install the stolen phenomenon of object, thus making
Become larger both directly and indirectly various losses.Some prevent stolen scheme is often that welding, disposable assembling etc. cannot be torn open
The method unloaded, can cause object artificially to have a mind to also cannot be smoothed out when changing, or pay very big cost.
Utility model content：
For solving the deficiency in above-mentioned technical problem, the purpose of this utility model is, provides one kind can overcome above-mentioned
Defect, meets the anti-theft fastening piece of theft-proof requirement.
Anti-theft fastening piece provided by the utility model, is characterized in that, including bolt, bolt passes through installs object, also wraps
Include anti-theft nut, be cased with sleeve, sleeve one end position Open architecture outside anti-theft nut, the bottom surface of the other end has through hole, bolt
Through through hole；It is provided with pad, the thickness of pad is more than the bottom thickness of sleeve, pad between anti-theft nut and installation object
External diameter is less than the diameter of a circle of sleeve bottom perforate.
The cylinder type that sleeve blocks for bottom surface, the through-hole diameter of bottom surface is less than the internal diameter of sleeve.
It is provided with pad, the thickness of pad is more than the bottom thickness of sleeve, pad between anti-theft nut and installation object
External diameter is less than the diameter of a circle of sleeve bottom perforate.
The tubular internal diameter of sleeve is more than the external diameter of anti-theft nut, and the total height of sleeve is more than pad and anti-theft nut is superimposed
Thickness.
Described anti-theft nut outer surface has groove, and groove is special-shaped slot.
Anti-theft nut is furnished with kit, and described kit is rod-like structure, is provided with the top of shaft-like mechanism
It is adapted outer male structure with anti-theft nut outer surface groove；Rod-like structure is hollow structure；The internal diameter of rod-like structure is more than outside bolt
The external diameter of screw thread, the external diameter of rod-like structure is less than the internal diameter of sleeve.
The beneficial effects of the utility model are：
1st, structure is simple, is easily installed.Cost is relatively low；2nd, the instrument such as conventional spiral shell knife, spanner, pliers, hammer all cannot
Effectively dismount, can effectively stop offender from being dismantled, oneself convenient dismounting can be ensured simultaneously again, exempt disposable
The drawbacks of assemble non-dismountable.
Brief description
Below in conjunction with the accompanying drawings and embodiment is described in further detail to this utility model：
Fig. 1 is this utility model Structure explosion diagram；
Fig. 2 is this utility model mounting structure schematic diagram；
In figure, 1, bolt；2nd, object is installed；3rd, pad；4th, sleeve；5th, anti-theft nut；6th, kit.
Specific embodiment
Theft-proof device for fasteners as shown in Figure 1, including bolt 1, pad 3, anti-theft nut 5, sleeve 4, kit 6,
Above article are to be linked in sequence, can be according to the matching requirements quantity combination in any of object.
The cylinder type that sleeve 4 blocks for bottom surface, there is individual through hole bottom surface, and through-hole diameter is less than the internal diameter of sleeve 4.
The thickness of pad is more than the bottom thickness of sleeve, and the external diameter of pad is less than the diameter of a circle of sleeve bottom perforate.This
Plant structure design, so that anti-theft nut is compressed simply by pad and object is installed, sleeve will not be fixed, sleeve can be free
Rotate and do not stress, will not occur to rotate the situation of anti-theft nut by turnbarrel, so that anti-theft nut can only be passed through supporting
Instrument is being operated.Sleeve can be protected anti-theft nut to exempt from external force and destroy.
The tubular internal diameter of sleeve 4 is more than the external diameter of anti-theft nut 5, and the total height of sleeve 4 is more than pad 3 and anti-theft nut 5
Superimposed thickness.After installing object and anti-theft fastening piece fastening, pad and anti-theft nut may be embodied in sleeve inner, sleeve
Can rotate freely and not stress.
Anti-theft nut 5 outer surface has special-shaped slot, can be a word, cross or vee gutter, can be with kit 6
Match.
Kit 6 is rod-like structure, is provided with adaptable with anti-theft nut outer surface groove outer on the top of shaft-like mechanism
Male structure；Rod-like structure is hollow structure；The internal diameter of rod-like structure is more than the externally threaded external diameter of bolt 1, the external diameter of rod-like structure
Internal diameter less than sleeve 4.
Specific work process：
Bolt 1 is passed through and installs after object 2, sleeve 4, pad 3, anti-theft nut 5 are assembled in order, then uses supporting work
Tool 6 is inserted in bolt, is fastened anti-theft nut 5 with its outer male structure or backs out, and reaching can antitheft and dismountable purpose.Permissible
Fixed demand according to fixation part arbitrarily increases and decreases cooperation.
Above-mentioned case study on implementation is only for understanding this utility model example, and is not to this utility model embodiment party
The restriction of formula.To belonging to the obvious change that spirit of the present utility model amplified out or change still in this utility model
Protection domain in.
