Abstract
The utility model discloses a double thread fastening device. The utility model comprises a bolt (1), the bolt (1) consists of a bolt head (2) and a thread section (3); the thread section (3) is provided with a double thread; the outer surface of the thread section (3) is provided with four to six grooves (5) along the axial direction. Compared with the prior art, the double thread fastening device of the utility model has high strength, convenient assembly and disassembly, and strong connecting reliability, can be widely used in the mechanical industry and has good application prospect.
Description
Technical field
The utility model relates to a kind of double thread screw securing means, belongs to technical field of fastening.
Background technique
Bolt, nut are to use fastening piece very widely, but it has himself inevitable shortcoming: 1, be given a shock in long-term the use, bolt and nut will unclamp gradually and come off, and it is unreliable to connect; 2, only depend on and be threaded, join strength is low.
The model utility content
The purpose of this utility model is: a kind of intensity height is provided, and installation and removal are convenient, and the double thread screw securing means that connection reliability is strong is to overcome the deficiencies in the prior art.
The utility model is to constitute like this:
It comprises bolt 1, and bolt 1 is made up of bolt head 2 and thread section 3; Thread section 3 is provided with double thread screw; Be provided with 4～6 grooves 5 at thread section 3 outer surfaces along axial direction.
Aforesaid double thread screw securing means, bolt head 2 is a cone shape, being provided with a cross section in the bottom of bolt head 2 is square or orthohexagonal slotted hole 4.
Above-mentioned double thread screw securing means is provided with a slotted hole 6 away from an end of bolt head 2 along axial direction at thread section 3; Slotted hole 6 is provided with a groove 7; In slotted hole 6, be provided with a special-shaped spring 8, and one section surface of exposing thread section 3 by groove 7 of special-shaped spring 8.
Above-mentioned double thread screw securing means, on bolt 1, be with a lining 9, end at lining 9 is provided with a cylindrical boss 10, be provided with a through hole 11 at boss 10 upper edge axis, the outside diameter of boss 10 is than the little 1～3mm of diameter of attachment hole on the connected piece, and the diameter of through hole 11 is less than the maximum diameter of bolt head 2 and greater than bolt 1 diameter; Being provided with a cross section at the other end of lining 9 is square or orthohexagonal shrinkage pool 12.
Above-mentioned double thread screw securing means also is with a snap ring 13 on bolt 1; Identical and the snap ring 13 of the outer shape of snap ring 13 and shrinkage pool 12 can embed in the shrinkage pool 12; Snap ring 13 is provided with a through hole 14, is provided with 1 boss 15 that can snap in the groove 5 in through hole 14 at least.
The helical pitch of double thread screw is big, can shorten installation, take-down time greatly.But the shrinkage pool 12 on snap ring 13 inlay bushers 9, the boss 15 on the snap ring 13 can embed the groove 5 of thread section 3 outer surfaces, have so just limited the rotation of bolt 1, and it is loosening to make whole device be difficult for.Abnormity spring 8 can be connected the motion of back restriction nut at nut with bolt 1, avoid it to come off.In the process that is screwed into nut of bolt 1, lining 9 is extruded into is close to connected piece, can play the effect of stay bolt head 2, the intensity of the whole device of increasing.Advantages such as owing to adopted technique scheme, double thread screw securing means of the present utility model has the intensity height, and installation and removal are convenient, and connection reliability is strong can be widely used in mechanical industry, and good prospects for application is arranged.During installation, lining 9 is inserted in the mounting hole of connected piece, the opposite side of bolt 1 from connected piece inserted the through hole 11 of lining 9, the groove 5 of snap ring 13 along thread section 3 is pushed in the shrinkage pool 12 of lining 9, when special-shaped spring 8 is pressed into slotted hole 6 nut is screwed into thread section 3, inserts with screw-driver and fix bolt 1, fastening nut in the slotted hole 4 and be extruded into until lining 9 and be close to connected piece.During dismounting,, can unclamp this device with fixing bolt 1 in the screw-driver insertion slotted hole 4, screwing off nut.
