Description
Technical field
The utility model relates to a kind of bolt, and more particularly, it relates to the lock body anti-demounting bolt that a kind of efficiency of assembling is high.
Background technique
In order to ensure vehicle startup system safe and reliable operation and protection driver's personal safety, between automobile lock body and steering column, adopt anti-demounting bolt to be connected, existing lock body anti-demounting bolt is that the form by the nut that ruptures prevents that lock body is disassembled.The nut coming off after fastening completing becomes a kind of not available waste material, needs to spend regular hour and energy to remove to arrange these waste materials on assembling line, not only wastes material and has affected to a certain extent efficiency of assembling.
Chinese patent notification number CN101701596A, discloses a kind of anti-demounting bolt, has hexagon head and the body of rod, at the body of rod, near one end of hexagon head, is provided with fastener head, and fastener head is connected with hexagon head by thin neck section, and the diameter of thin neck section is less than the diameter of the body of rod.After bolt tightening, continue to strengthen screw-down torque, bolt is twisted off from thin neck section, hexagon head comes off, and only has fastener head exposed in the outside of link, because fastener head cannot twisting, so reach the object that bolt prevents dismounting.But the hexagon head coming off after fastening completing becomes a kind of not available waste material, on assembling line, need to spend regular hour and energy to remove to arrange these waste materials, not only waste material and affected to a certain extent efficiency of assembling.
Model utility content
The utility model has overcome the nut splitting away off after existing anti-demounting bolt is tightened and has become a kind of not available waste material, not only wasted material, and need to take time and arrange the deficiency that these waste materials affect efficiency of assembling, a kind of lock body anti-demounting bolt is provided, the nut splitting away off after bolt tightening can utilize again, and a nut can be used on a plurality of bolts, has not only saved material, and do not need to take time and arrange nut waste material, efficiency of assembling is high.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of lock body anti-demounting bolt, comprise double-screw bolt and nut, double-screw bolt and nut removably connect, and double-screw bolt upper end is provided with connecting head, connecting head upper-end surface is provided with annular connecting groove, in connecting groove, be provided with postive stop baffle, nut lower end surface is provided with the protruding connecting ring with connecting groove adaptation, and connecting ring is provided with the restraining groove with postive stop baffle adaptation, connecting ring is connected in connecting groove, and postive stop baffle is connected in restraining groove.
Nut when in use nut together with Stud connection, dismantling device is socketed on nut and rotating nut, because the postive stop baffle on double-screw bolt connects in spacing restraining groove on nut, so the rotation of the rotation of nut drive double-screw bolt, just can be by screwing up stud by extracting tool.After screwing up stud, axially extract nut, make nut separated with double-screw bolt, now just can not adopt general on the market extracting tool to carry out disassembling section to double-screw bolt.And the nut of extracting can be for other the dismounting operation of double-screw bolt, a nut can be used on a plurality of bolts.The nut that lock body anti-demounting bolt splits away off after tightening can utilize again, and a nut can be used on a plurality of bolts, has not only saved material, and does not need to take time and arrange nut waste material, and efficiency of assembling is high.
As preferably, the cylindrical structure of connecting head, annular connecting groove, connecting head, double-screw bolt three coaxially arrange, and connecting head and double-screw bolt are one-body molded.The one-body molded join strength of connecting head and double-screw bolt is good.
As preferably, nut comprises hexagon head and is connected to the attachment post of hexagon head lower end, and connecting ring is connected on the lower end surface of attachment post, hexagon head, attachment post, the moulding of connecting ring three in one.The nut intensity consisting of hexagon head and attachment post is good, is difficult for infringement, long service life in rundown process.
As preferably, restraining groove connects outer wall and the inwall of connecting ring, and postive stop baffle lower end is connected on the bottom surface of connecting groove, and the both sides of postive stop baffle are connected on the two side of connecting groove.Spacing reliable in the process that the restraining groove that this structure arranges and postive stop baffle rotate at nut.
As preferably, the diameter of connecting head is greater than the diameter of double-screw bolt, the diameter of attachment post and the equal diameters of connecting head.The diameter of connecting head is greater than the diameter of double-screw bolt, more laborsaving in tightening the process of double-screw bolt.
Compared with prior art, the beneficial effects of the utility model are: the nut that lock body anti-demounting bolt splits away off after tightening can utilize again, and a nut can be used on a plurality of bolts, has not only saved material, and do not need to take time and arrange nut waste material, efficiency of assembling is high.

Embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described specifically:
Embodiment: a kind of lock body anti-demounting bolt (referring to accompanying drawing 1), comprise double-screw bolt 1 and nut 2, double-screw bolt 1 and nut 2 removably connect.Double-screw bolt 1 upper end is provided with connecting head 3, and connecting head 3 upper-end surfaces are provided with annular connecting groove 4, the cylindrical structure of connecting head 3, and annular connecting groove 4, connecting head 3, double-screw bolt 1 three coaxially arrange, and connecting head 3 and double-screw bolt 1 are one-body molded.In connecting groove 4, be provided with postive stop baffle 5, nut 2 lower end surfaces are provided with the protruding connecting ring 6 with connecting groove 4 adaptations, and connecting ring 6 is provided with the restraining groove 7 with postive stop baffle 5 adaptations, and connecting ring 6 is connected in connecting groove 4, and postive stop baffle 5 is connected in restraining groove 7.Restraining groove 7 connects outer wall and the inwall of connecting ring 6, and postive stop baffle 5 lower ends are connected on the bottom surface of connecting groove 4, and the both sides of postive stop baffle 5 are connected on the two side of connecting groove 4.Nut 2 comprises hexagon head 8 and the attachment post 9 that is connected to hexagon head 8 lower ends, and connecting ring 6 is connected on the lower end surface of attachment post 9, hexagon head 8, attachment post 9, connecting ring 6 three in one moulding.The diameter of connecting head 3 is greater than the diameter of double-screw bolt 1, the equal diameters of the diameter of attachment post 9 and connecting head 3.
Nut when in use nut together with Stud connection, dismantling device 10 is socketed on nut and rotating nut (referring to accompanying drawing 2), because the postive stop baffle on double-screw bolt connects in spacing restraining groove on nut, therefore the rotation of nut drives the rotation of double-screw bolt, just can be by screwing up stud by extracting tool.After screwing up stud, axially extract nut, make nut separated with double-screw bolt, now just can not adopt general on the market extracting tool to carry out disassembling section to double-screw bolt.And the nut of extracting can be for other the dismounting operation of double-screw bolt, a nut can be used on a plurality of bolts.The nut that lock body anti-demounting bolt splits away off after tightening can utilize again, and a nut can be used on a plurality of bolts, has not only saved material, and does not need to take time and arrange nut waste material, and efficiency of assembling is high.
Above-described embodiment is a kind of preferably scheme of the present utility model, not the utility model is done to any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technological scheme that claim records.
