The specific embodiment
To understand in order technical characterictic of the present invention, purpose and effect being had more clearly, to contrast accompanying drawing at present and specify the specific embodiment of the present invention.
Extremely shown in Figure 4 like Fig. 1; A preferred embodiment for safety hook of the present invention; This antitheft hook comprises coupler body 100; Coupler body 100 comprises the main part 110 that is half-surrounded, and main part 110 is the opening 113 of main part 110 between having first terminal 111 and second terminal 112, the first terminal 111 and second terminal 112.For the equipment on the main part 100 that prevents to hang over hook is arbitrarily taken away; The antitheft hook also comprises safety cock sheet 200; Safety cock sheet 200 is used to seal the opening 113 of main part 110; First end 210 of safety cock sheet 200 is rotatably connected on first end 111 of main part 110, and second end 220 of safety cock sheet 200 is against the second terminal part below 112 of main part 110.In order to make safety cock sheet 200 keep the state of the opening 133 of sealing main part 110; This antitheft hook also comprises clamping screw 300; Clamping screw 300 is a heterotypic bolt, comprises screw rod 310 and special-shaped head 320, the screw 114 that first terminal 111 of main part 110 has over against safety cock sheet 200; Clamping screw 300 is installed in the screw 114, and the screw rod 310 of clamping screw 300 withstands safety cock sheet 200 makes safety cock sheet 200 keep the state of the opening 113 of sealing main part 110.Screw rod 310 withstands between first terminal 111 part that is rotationally connected of second end 220 and safety cock sheet 200 and main part 110 of safety cock sheet 200; When screwing clamping screw 300; Second end 220 of safety cock sheet 200 is pressed on the second terminal part below 112 of main part 110, and safety cock sheet 200 main part 110 relatively rotates.Because clamping screw 300 is a heterotypic bolt, only could bolt be screwed out by means of the adaptive specific purpose tool of this heterotypic bolt, because common people do not have specific purpose tool, thus the antitheft hook of not opening, thus make the antitheft hook have the effect of antitheft.
Further, in order better to play the effect of antitheft, in the present embodiment; The end of screw 114 has the counterbore 115 of the head 320 of ccontaining said clamping screw 300; The head 320 of clamping screw 300 submerges in the counterbore 115, like this during clamping screw 300 lockings, because head submerges in the counterbore 115; If not by specific purpose tool, at all can't turn clamping screw 300.In this enforcement, the special-shaped head 320 of clamping screw 300 has interior delthyrium 321, is provided with newel 322 in the interior delthyrium 321, and the professional screwdriver that must add centre bore by the triangle termination of correspondence could screw out clamping screw 300.It will be appreciated that special-shaped head 320 does not limit to the structure that adds newel with delthyrium, also can be other Practical deformation structures, and for example interior four directions, interior six side's lamp non-circular holes add structures such as newel.
In the present embodiment; In order to make the antitheft hook have the effect of common safety hook, first end 210 of safety cock sheet 200 is rotationally connected through bearing pin 230 and first terminal 111, is with torsion spring 400 on the bearing pin 230; When not locking clamping screw 300; Safety cock sheet 200 is under the effect of torsion spring 400, and its second end 200 is against on the main part 110, can prevent that the equipment that hangs on the hook from deviating from; And when needs were hung into equipment, second end 220 that only need push safety cock sheet 200 can be opened hook hanging equipment is gone into.In the present embodiment, torsion spring 400 is a torsion spring, and torsion spring 400 comprises by first torsion spring 410 of same steel wire coil coiled and second torsion spring 420; Two torsion springs, 420 parallel settings; The centre has connecting portion 401, and the both sides moment of torsion that the torsion spring structure makes is balanced, and elasticity is better.The location of torsion spring 400 for ease, first terminal 111 tools are provided with and are used to place draw-in groove 116, the first torsion springs 410 of torsion spring 400 and the connecting portion 401 of second torsion spring 420 is stuck in the draw-in groove 116.
In the present embodiment; Further; Because second end 220 swing of safety cock sheet 200 is opened the opening of hook, especially when safety cock sheet 200 is long, be provided with a spacing breach 221 in order to prevent at second end 220 of safety cock sheet 200; Spacing breach 221 is stuck on the second terminal part below 112 of main part 110, can make the anti-theft effect of hook better like this.
The coupler body 100 of antitheft hook of the present invention also comprises the standing screw 120 that is extended back and formed by first terminal 111 of main part 110; Rely on this standing screw 120 can antitheft hook be installed in the occasion that wall etc. needs to install the antitheft hook; Further; Can on standing screw 120, put the expansion sleeve (not shown), form expansion bolt, can make things convenient on the firm fixed wall.Fig. 5 promptly shows antitheft of the present invention and hangs over the sketch map on the wall.It will be appreciated that first terminal 111 also can extend back any suitable fixed structure, is not limited to the form of screw rod.
The coupler body 100 of hook of the present invention is processed by steel, and the outer surface of coupler body 100 is enclosed with nylon, can play etch-proof effect.
In antitheft of the present invention hook, the safety cock sheet is withstood the shape body of the opening that keeps the sealing hook by heterotypic bolt, need just can the turn heterotypic bolt by specific purpose tool, open hook.Because hook can not arbitrarily be opened, and can prevent that the equipment that hangs on the hook is stolen.Antitheft hook of the present invention has advantages such as simple in structure, that cost is low, theftproof performance is good.
Combine accompanying drawing that embodiments of the invention are described above; But the present invention is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of forms, these all belong within the protection of the present invention.
