By adopting technique scheme, on described acorn nut, claw is set, to prevent that it from being screwed out, antitheft, the structural strength that kept six square nuts not only, double thread produces and destroys, and aspect assembling, only needing that normal method is installed uses, very convenient, and claw does not have too large requirement to machining accuracy; Claw is arranged on the hole wall of described counterbore, keeps the structure of acorn nut outside; The elasticity that breach can make blade tooth is set, makes claw there is larger coupling mechanism force, and the energy quantity of breach and the quantity of blade tooth equate, clamping force is uniformly distributed; Described claw towards six square nut axle center and cap direction arrange, after acorn nut screws, claw can prop up the screw thread of bolt, prevents that acorn nut from being screwed out; Meanwhile, the Assurance of Size claw of restriction blade tooth does not affect the normal use of described acorn nut when playing anti-theft function; In addition, evanohm has high strength and corrosion resistance, and the alloy forming with iron and nickel is commonly called as stainless steel, in plated surface one deck nickel chromium triangle coating of described six square nuts, in the time of preventing from turning round and round tight acorn nut, skids, and can also strengthen its mission life-span; Aluminum alloy material has very high plasticity, and intensity is high, density is little, good corrosion resistance, by aluminum alloy material, forms claw processing, easily manufactured, guarantees the working life of described claw.
The utility model is further set to: described cap top is provided with for the nested inner hexagonal hole of inner hexagon spanner.
By adopting technique scheme, at top, inner hexagonal hole is set, environment at some narrow spaces, can be according to actual conditions, change different instruments and screw acorn nut, when particularly the radial space of the surrounding of acorn nut is not enough to support that open-end wrench uses, can utilize axial space, use inner hexagon spanner.
The utility model is further set to: the outer surface of described six square nuts is provided with the anti-skidding lines perpendicular to the axis of six square nuts.
By adopting technique scheme, in the side of bolt head, anti-skidding lines is set, prevent that acorn nut from skidding when hand is twisted, and strengthens operator's hand and the friction between bolt head.
The utility model is further set to: described six square nuts comprise internal thread, and described internal thread is provided with locking nylon ring near one end of block.
By adopting technique scheme, after described acorn nut and bolt screw, nylon ring has the effect of tightening, and prevents that acorn nut from getting loose.
Accompanying drawing explanation
Fig. 1 is the utility model anti-theft capped nut embodiment's structural representation;
Fig. 2 is the utility model anti-theft capped nut embodiment's schematic diagram.
Reference character: 1, six square nuts; 11, internal thread; 2, block; 21, inner hexagonal hole; 22, anti-skidding lines; 3, claw; 31, blade tooth; 32, breach; 4, counterbore; 5, locking nylon ring.
Embodiment
Referring to figs. 1 through Fig. 2, the embodiment of the utility model anti-theft capped nut is described further.
As shown in Figure 1 to Figure 2, a kind of acorn nut, comprises six square nut 1 and caps, also comprises the claw 3 for preventing that six square nuts 1 from being screwed out.Claw 3 is set on described acorn nut, to prevent that it from being screwed out, antitheft, the structural strength that kept six square nuts 1 not only, double thread does not produce and destroys, and aspect assembling, only need that normal method is installed and use, very convenient, meanwhile, 3 pairs of machining accuracies of claw do not have too large requirement.
Described six square nuts 1 are provided with the counterbore 4(coaxial with it away from one end of cap and it should be noted that herein, and the degree of depth of counterbore 4 will guarantee that six square nuts 1 leave enough positions internal thread 11 is set), claw 3 is arranged on the hole wall of described counterbore 4.Claw 3 is arranged on the hole wall of described counterbore 4, keeps the structure of acorn nut outside.
Described claw 3 comprises some blade tooths 31, between every two adjacent blade tooths 31, all forms breach 32, and the quantity of described breach 32 equates with the quantity of blade tooth 31; Described claw 3 towards six square nut 1 axle center and cap direction arrange.The elasticity that breach 32 can make blade tooth 31 is set, makes claw 3 there is larger coupling mechanism force, and the quantity of energy breach 32 equates with the quantity of blade tooth 31, and clamping force is uniformly distributed; Meanwhile, described claw 3 towards six square nut 1 axle center and cap direction arrange, after acorn nut screws, claw can prop up the screw thread of bolt, prevents that acorn nut from being screwed out.
Described cap top is provided with for the nested inner hexagonal hole 21 of inner hexagon spanner.Inner hexagonal hole 21 is set at top, at the environment of some narrow spaces, can be according to actual conditions, change different instruments and screw acorn nut, when particularly the radial space of the surrounding of acorn nut is not enough to support that open-end wrench uses, can utilize axial space, use inner hexagon spanner.
The outer surface of described six square nuts 1 is provided with the anti-skidding lines 22 perpendicular to the axis of six square nuts 1.Anti-skidding lines 22 is set in the side of bolt head, prevents that acorn nut from skidding when hand is twisted, and strengthens operator's hand and the friction between bolt head.
The surface of described six square nuts 1 is coated with nickel chromium triangle coating.Evanohm has high strength and corrosion resistance, and the alloy forming with iron and nickel is commonly called as stainless steel, in plated surface one deck nickel chromium triangle coating of described six square nuts 1, in the time of preventing from turning round and round tight acorn nut, skids, and can also strengthen its mission life-span.
Described six square nuts 1 comprise internal thread 11, and described internal thread 11 is provided with locking nylon ring near one end of block 2.After described acorn nut and bolt screw, nylon ring has the effect of tightening, and prevents that acorn nut from getting loose.
Described claw 3 consists of aluminum alloy material.Aluminum alloy material has very high plasticity, and intensity is high, density is little, good corrosion resistance, by aluminum alloy material, forms claw 3 processing, easily manufactured, guarantees the working life of described claw 3.
The above makes preferred implementation of the present utility model, does not depart from for the person of ordinary skill of the art under the prerequisite of the utility model principle, can also make some modification and improvement, and these also should be considered as protection domain of the present utility model.
