Abstract
The utility model discloses a locking-tight nut mainly comprising a locking part and a drive part. The locking part and the drive part form a whole and axial through holes communicated with each other are formed in the locking part and the drive part. A break is formed between the locking part and the drive part. A polyhedron is disposed on the outer surface of the drive part. The inner through hole of the locking part is provided with a thread. The inner side of an opening of the locking part is provided with an accommodating groove. The locking-tight nut has the advantages that the nut is all made of titanium alloy, and accordingly the weight of the locking-tight nut is low, fatigue resistance is fine and locking performance is high; the locking-tight nut is especially suitable for the high-end fields such as aerospace having high requirements.
Description
Technical field
The utility model relates to the technical field of fastening piece, more particularly relates to the technical field of nut.
Background technique
Nut is a kind of fastening piece of cylinder shape belt tapped hole of fitted bolt use.During use, to have externally threaded cylindrical body screw rod earlier easily is set in the hole of two links, tighten at bolt with nut again and get final product, mount and dismount all very convenient, and can use repeatedly, but its employed power when tightening of plain nut is decided on the operator now, therefore, little when big during its screwing force, will produce many potential safety hazards when in high-end fields such as space flight and aviation, using, because existing nut adopts iron to make mostly, its weight is bigger, also is not suitable for using in high-end fields such as space flight and aviation in addition.
The model utility content
The purpose of this utility model provides a kind of in light weight in order to solve above-mentioned deficiency exactly, and anti-loose ability is strong, and anti-fatigue performance is good, the efficiency of assembling height, and can effectively control the high locking nut of screwing force.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
A kind of high locking nut, it mainly is made of lock portion and drive part, described lock portion and drive part are a whole and inner axial hole that connects that offers, between this lock portion and drive part, be provided with fracture, described drive part outer surface is provided with polyhedron, interior side through hole at this lock portion offers screw thread, is provided with capaciting material groove in the opening inboard of this lock portion.
Described lock portion and drive part adopt titanium alloy material to be made.
The polyhedron of described drive part outer surface is hexahedron.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: this nut adopts titanium alloy material to be made fully, in light weight, anti-fatigue performance is good, anti-loose ability is strong, in use, by turning drive part, lock portion and drive part will rotate on lock bolt simultaneously, when screwing force acquires a certain degree, drive part will disconnect at incision position with lock portion, tightens action thereby finish, not only the efficiency of assembling height, and the big I of screwing force in when assembling effectively controls, and is particularly suitable for using the field at high-end high requests such as space flight and aviations.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right TV structure schematic representation of Fig. 1.
Embodiment
By illustrated in figures 1 and 2, a kind of high locking nut, it mainly is made of lock portion 1 and drive part 2, described lock portion 1 and drive part 2 adopt titanium alloy material to be made, lock portion 1 and drive part 2 are a whole and inner axial hole 3 that connects that offers, between this lock portion 1 and drive part 2, be provided with fracture 4, so that when screwing force reaches certain value, disconnect the neat fracture surface of formation from this fracture 4, described drive part 2 outer surfaces are provided with hexahedron 5, conveniently turn by instrument in use, interior side through hole at this lock portion 1 offers screw thread 6, opening inboard at this lock portion 1 also is provided with capaciting material groove 7, in order to hold the unnecessary material that pushes out when lock bolt assembles, also is beneficial to locking nut simultaneously and matches with lock bolt.
