The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of simple in structure, processing ease, the combined type anti-theft screw that combines with multi-functional packing ring of Chang'an, screw satisfactory for result admittedly for a long time are provided.
The technological scheme that provides according to the utility model, described combined type anti-theft screw, comprise bolt head, nut and matrix packing ring, nut, bolt head adopt cylindrical or are truncated cone, truncated cone and band be the shirt rim down, the truncated cone angle is less than 35 degree, and following shirt rim diameter is equal to or greater than the bolt head diameter.
The lower end, shirt rim is provided with 2-8 locking tooth under the described truncated cone, the locking tooth crown left, angle less than 70 the degree.Described nut one end is provided with 2-8 locking tooth, the locking tooth crown left, angle less than 70 the degree.
Described bolt head, nut end face be provided with 2-6 equal portions, the central angle number of degrees be 60-180 °, by all equidistant be processed into rotary, reverse along circle inclined-plane fastening teeth, fastening teeth all is the fan shape, the reverse incline of fastening teeth is inside or outward-dipping, and the inclined-plane of angle in length and breadth of every reverse incline is not more than 30 degree.
Described multi-functional matrix packing ring is the bottle cap shape, and periphery highly is lower than nut or bolt head side height; Matrix packing ring diameter is greater than or equal to nut, bolt head diameter.The antirattle spring sheet that the outside perk of 1-3 sheet is arranged in the bottom design of matrix packing ring, the antirattle spring sheet is opened counterclockwise or is laterally opened, be provided with the retaining sheet of the inside perk of 2-5 sheet simultaneously in the bottom of matrix packing ring, retaining sheet is opened clockwise, its direction should be opposite with the locking tooth direction, and retaining sheet span and locking tooth are complementary.
Compared with the prior art the utility model has the following advantages:
1, simple and reasonable for structure, certain scientific and technological content is arranged;
2, processing ease advances then and tightens, and moves back then nature, and fastening performance is good;
3, the screw moulding is special, and has shield not have lance, and screw and multi-functional packing ring mutually combine, and consolidates Chang'an for a long time, and anti-theft effect is very good;
4, adopt above-mentioned this design concept, can also process various screw and derived product with same feature.Antitheft function is not only arranged, and also have certain anti-fake effect;
5, be convenient to promote the use of, can be widely used in military affairs, national defence, electric power, telecommunications, railway, highway communication, the long-term permanent communal facility of indoor and outdoor and the antitheft place of all needs.To creating harmonious society, be of great practical significance.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, comprise bolt head 1, cylindrical body nut 2, matrix packing ring 3, fastening teeth 4,5, locking tooth 6,7, antirattle spring sheet 8, retaining sheet 9, following shirt rim 10 etc.
One, is material with the round steel directly, is processed into cylindrical body nut 2 or is truncated cone, and have shirt rim 10 down; The shirt rim diameter is protruded greater than nut, bolt head diameter less than 30 degree in bolt head 1 truncated cone angle, and nut, bolt head profile pattern can be general; Simultaneously for playing better anti-theft effect, be provided with at lower end, bolt head shirt rim and nut one end face and be provided with 2-8 the impartial locking tooth 6,7 that in order, tilts to low up time by height, crown left, the angle degree is less than 70 degree.Two, adopt the fastening mode of enforcement on the cylinder end face, promptly be provided with fastening teeth 4,5 at bolt head 1 top end and nut 2 one end faces.Be divided into the 2-6 equal portions according to the screw circumferential size, central angle is the 60-180 degree, becomes rotary according to all equidistant in surface Machining then, and reverse fastening teeth 4,5 along the circle clinohedral is the fan shape.Every part of inwardly (center) or outwards (periphery) inclination of reverse incline simultaneously, the angle inclined-plane is not more than 30 degree in length and breadth.Only advance not move back when this fastening pattern is used, effect is splendid.Three, prepare multi-functional matrix packing ring 3, be the bottle cap shape, played effect firm, shockproof, that escort.Periphery highly is lower than nut 2 or bolt head 1 periphery height; Diameter is greater than nut 2, bolt head 1, and benefit is to have protected screw, has increased the destruction difficulty.The characteristics of multi-functional matrix packing ring 3 are: be provided with the antirattle spring sheet 8 of the outside perk of 1-3 sheet in its bottom, antirattle spring sheet 8 is (counterclockwise) unlatching left, also looks actual conditions and laterally opens.The retaining sheet 9 of the inside perk of design 2-5 sheet, retaining sheet 9 be (clockwise) unlatching to the right, and its direction should be opposite with locking tooth 6 or locking tooth 7.Require: retaining sheet 9 spans must be complementary with locking tooth 6 or locking tooth 7, the angle palpus opposing parallel that retaining sheet 9 and locking tooth 6 or locking tooth 7 tilt, guarantee that retaining sheet 9 interlocks with locking tooth 6 or locking tooth 7 when fastening and implement completely, give full play to the antitheft effect of its retaining.In this multi-functional matrix packing ring 3 practical operations also can with bolt head 1 supporting using simultaneously.
The utlity model has the working principle of only advancing not move back, structure is ingenious, if the corresponding fastened tools of preparation, but with regard to easy manipulation.In case fastening, Song Bukai, constantly stubborn, unshakable, the burglar can only hope it heave a sigh.
