Description
Technical field
The present invention relates to a kind of anti-loose anti-theft auxiliary connection, especially a kind of nut, packing ring and bolt of comprising, nut and bolt wire connection, packing ring is between nut and bolt head; The bottom surface that described nut contacts with packing ring is to form helical teeth that constitute, that have center screw bottom surface, radial a plurality of wedge shapes inclined-plane by its peripheral angles top of middle mind-set; Described packing ring and supporting nut surface of contact be, the anti-loose anti-theft auxiliary connection of the pitch face of the band mesopore that matches with described helical teeth bottom shape.
Background technique
The theft preventing method that the fastening piece link is commonly used mostly is the brill sky greatly and wears pin, the anti-revolution of nut fluting dress retaining needle roller, and the unit bolt nut draw-bore is assembled the back and is beaten methods such as tenon, and there is the operating procedure complexity in these class methods, and product structure is also complicated, defect of high cost; For solving this class problem, Chinese patent literature CN2675931 discloses a kind of safety attachment, form by supporting nut, nut and bolt, it is characterized in that: nut is an abnormity nut 1, be that it has regular hexagon periphery 7, the bottom surface that contacts with nut 2 is form helical teeth that constitute, that have center screw bottom surface, radial six wedge shape inclined-planes 8 by its peripheral angles top of middle mind-set, and the end face of this nut to be the dome 6 of sealing; Nut is an abnormity nut 2, be to be in its upper and lower surfaces with the supporting nut 1 or the surface of contact of bolt 5, with the suitable hollow pitch face 14 in helical teeth bottom surface that constitute, that have center screw, radial six the wedge shape inclined-planes of abnormity nut 18, and with link 4 contacted another sides be circular planes, on this plane, has the vertical sharp bar 9 of single wedge surface by middle mind-set edge trend, single wedge surface direction of point bar 9 is in the front end that screws direction, and the periphery of nut 2 is the circle edge with non-axisymmetric loading and unloading notch 10; Bolt is a special shaped screw bolt, and promptly it has dome shape bolt head 11, and the bottom surface of the position, connecting part of this bolt head and screw rod is, has the disk 13 by the vertical sharp bar 9 of single wedge surface of middle mind-set edge trend, and single wedge surface direction of sharp bar 9 is in the front end that screws direction; Or the bolt head of this bolt is hexagon bolt head 12, and the bottom surface of the position, connecting part of this bolt head and screw rod is, with the hollow pitch face 14 of abnormity nut 2 adaptive, have helical teeth bottom surfaces 15 that radial six wedge shape inclined-planes constitute.Its advantage is to use in, the frequent environment of vibratory impulse big in difference variation can not get loose, and circumference nut edge is shaped on non-axisymmetric loading and unloading notch and has antitheft effect, and the hexagon nut of sealing dome can prevent that rainwater from invading and avoid corrosion.But there is the problem of three aspects in this safety attachment, the one, and the helical teeth surface of contact of this fastening piece discloses insufficient, when helical teeth surface of contact area was too small, during anti-nutting, the pitch face of nut can damage, and the thread of bolt can not damage, and nut can withdraw from the same old way; The 2nd, the helical teeth angle of nut is not required, if the helical teeth angle too small, thread can not damage, nut can withdraw from the same old way; If the helical teeth angle is excessive, then packing ring can rotate together along with nut, together withdraws from; The 3rd, the helical teeth bottom surface is divided into six parts, then every part of equal portions area is little, and nut withdraws from easily.
Summary of the invention
The technical problem that the present invention solves is to overcome above-mentioned shortcoming, and a kind of torsional type anti-loose anti-theft bolt connect sets of anti-loose anti-theft better effects if is provided.
Technological scheme of the present invention is: add a profile gasket between the nut on the bolt, the bottom surface of nut is designed to the helical teeth bottom surface, the one side that packing ring is relative with the nut bottom surface is designed to the pitch face that matches with the nut bottom surface, according to the mechanics parallelogram law, lift angle when the angle of inclination of nuts and washers more than or equal to screw thread, and when the area of contact of nut and pad is equal to or greater than the area of contact of bolts and nuts, when applying opposite force to nut, screw thread and bolt part screw thread will be turned round and cut distortion, and can not swing offset and withdraw from, to reach antitheft purpose.
A kind of torsional type anti-loose anti-theft bolt connect sets provided by the present invention comprises nut, packing ring and bolt, nut and bolt wire connection, and packing ring is between nut and bolt head; The bottom surface that described nut contacts with packing ring is to form helical teeth that constitute, that have center screw bottom surface, radial a plurality of wedge shapes inclined-plane by its peripheral angles top of middle mind-set; Described packing ring and supporting nut surface of contact are, the pitch face of the band mesopore that matches with described helical teeth bottom shape, the angle of inclination of nuts and washers is greater than the lift angle of screw thread, and the angle of inclination is the 6-9 degree, and the helical teeth bottom surface of nut and the pitch face of packing ring are divided into 3-5 part; The area of the area of the helical teeth bottom surface of nut and the pitch face of packing ring is all greater than the developed area of thread.
Described optimum tilt angle is 8 degree.
The best of the helical teeth bottom surface of described nut and the pitch face of packing ring is divided into 4 parts.
Anti-skid rack by middle mind-set edge directive is arranged on the described packing ring one side relative with the bolt head bottom surface.
Anti-skid rack A by directive edge, center is arranged in described bolt head bottom surface.
Described nut is five sides, six sides or all directions nut.
The diameter of described packing ring is less than contact with it diameter of portion of nut.
The present invention is owing to adopted the lift angle of the angle of inclination of nuts and washers greater than screw thread, and the angle of inclination is the 6-9 degree, the structure that the helical teeth bottom surface of nut and the pitch face of packing ring are divided into 3-5 part, behind clockwise fastening nut, during another mistake hour hands swivel nut, the screw thread of screw bolt and nut can be subjected to the power of two different amount, the screw thread desire can take place upwards, and the downward displacement of inclination flank of tooth desire, a pair of like this contradiction power when the area of the pitch face of the area of the helical teeth bottom surface of nut and packing ring during all greater than the developed area of thread, can make the distortion of screw thread generation retrospective and produces stripped thread, then nut can revolve, and reaches antitheft better purpose.
