Abstract
The utility model discloses a snap type efficient locking bolt which comprises a head and a screw. The screw comprises a threaded portion and a stud, the diameter of each external thread of the threaded portion is smaller than that of the stud, a draw bar is further arranged at the tail of the screw, and a fracture is formed between the draw bar and the screw. The snap type efficient locking bolt has the advantages that the snap type efficient locking bolt is light, and is good in anti-fatigue performance, high in assembly efficiency and particularly suitable for high-end fields of aerospace, aviation and the like with high requirements, the mounted stud can simultaneously bear longitudinal loading force and transverse loading force and is high in anti-loose performance,, and motorized single-side operation can be implemented.
Description
Technical field
The utility model relates to the technical field of fastening piece, more particularly relates to the technical field of bolt.
Background technique
Bolt is a kind of cylindrical threaded fastening piece of adapted nut.It is mainly by head with have externally threaded cylindrical body screw rod two-part and form, this screw portion be cylindric and diameter consistent, during use, to have externally threaded cylindrical body screw rod easily is set in the hole of two links, get final product with nut screwing clamping again, mount and dismount all very convenient, but it only can carry certain thrust load power, because existing bolt adopts iron to make mostly, its weight is bigger in addition.In high-end fields such as space flight and aviation, the bolt that needs can not only bear longitudinal loading power, and also requirement can be born certain lateral load force, and need alleviate himself weight to greatest extent.
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 bear the high lock bolt of the formula of breaking of vertical and horizontal loading force simultaneously.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
The high lock bolt of the formula of breaking is made up of head and screw rod, and described screw rod is made of screw thread and double-screw bolt two-part, and the external thread diameter of helical thread portion is less than the diameter of double-screw bolt part, and the afterbody of described screw rod also is provided with pull bar, is provided with fracture between this pull bar and the screw rod.
This bolt has been adopted titanium alloy material and has been made.
The external thread diameter of described helical thread portion is littler 1-4 millimeters than the diameter of double-screw bolt part.
Described pull bar is provided with annular slideproof tooth.
Described pull bar diameter is less than or equal to the external thread diameter of screw portion.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: this bolt adopts titanium alloy material to be made fully, in light weight, anti-fatigue performance is good, in use, the diameter in two link holes is slightly less than the diameter of screw portion double-screw bolt, be expressed in the hole of two links by the double-screw bolt of pull bar with screw portion, utilize the interference fit in screw rod and hole, make the bolt after installing to bear the vertical and horizontal loading force simultaneously, anti-loose ability is strong, it can realize motor-driven single face operation in addition, and the efficiency of assembling height 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.
Embodiment
By shown in Figure 1, the high lock bolt of the formula of breaking, formed by head 1 and screw rod, described screw rod is made of screw thread 2 and double-screw bolt 3 two-part, and the external thread diameter of screw thread 2 parts is advisable for little 1-4 millimeters than the diameter of double-screw bolt 3 parts, and the afterbody of described screw rod also is provided with pull bar 4, this pull bar 4 is provided with annular slideproof tooth 5, and these pull bar 4 diameters are less than or equal to outside thread 2 diameters of screw portion, are provided with fracture 6 between this pull bar 4 and the screw rod, and this bolt has been adopted titanium alloy material and has been made.In use, the diameter in two link holes is slightly less than the diameter of screw portion double-screw bolt 3, by pull bar 4 double-screw bolt 3 extruding types of screw portion are moved in the hole of two links, when pulling force acquires a certain degree, pull bar 4 can disconnect from fracture 6 with screw rod, thereby finishes the installation process of bolt, and this bolt has utilized the interference fit in screw rod and hole just, make the bolt after installing can bear the vertical and horizontal loading force simultaneously, anti-loose ability is strong.
Claims (5)
