Abstract
A kind of hexagonal torsional shear type bolt, including breach is cut in nut, screw rod, threaded portion, torsion haircut, shrinkage pool, torsion, the center line that above-mentioned nut, screw rod, threaded portion, torsion haircut, shrinkage pool, torsion cut breach is arranged on the same line；Described nut one end is connected with screw rod, and the nut other end is provided with polygon shrinkage pool；The major part of described screw rod is provided with screw thread, forms threaded portion；Described threaded portion end is connected to torsion haircut, and turning round haircut is polygon projection, and the polygon shrinkage pool shapes and sizes adaptation of polygon projection and nut, polygon projection can insert the shrinkage pool of nut smoothly；Described torsion haircut is provided with torsion with junction, threaded portion and cuts breach, and junction is inverted cone.The utility model provides the benefit that: bolt is in rundown process, when moment of torsion exceedes determination value, turns round haircut and falls from screw rod tip breakages, ensure that the appropriate level screwing, and keep bolt end surfacing.Turn round the post-rift bolt of haircut simultaneously, can continue to reuse.
Description
Technical field
The utility model belongs to metal fastenings field, relates to a kind of hexagonal torsional shear type bolt.
Background technology
Bolt as fastener application widely, is generally used in combination with nut or screw, but bolt makes
Used time rotation too tight, will damaged screw, be unfavorable for permanent fastening, rotation too loose, be easily caused again bolt and shake.
At present, torsional shear type bolt turns round, by arranging on bolt, the purpose that haircut reaches to apply properly to screw power, but turns round
It is not generally very smooth that haircut stays the section on bolt when fracture, at some to the strict place nothing of flatness requirement
Method uses.
Utility model content
The purpose of this utility model is to solve posed problems above, provides a kind of hexagonal torsional shear type bolt.
The technical solution of the utility model is such that
A kind of hexagonal torsional shear type bolt, including breach, above-mentioned spiral shell are cut in nut, screw rod, threaded portion, torsion haircut, shrinkage pool, torsion
Cap, screw rod, threaded portion, torsion haircut, shrinkage pool, torsion cut the center line setting of breach on the same line；
Described nut one end is connected with screw rod, and the nut other end is provided with polygon shrinkage pool；
The major part of described screw rod is provided with screw thread, forms threaded portion；
Described threaded portion end is connected to torsion haircut, and turning round haircut is polygon projection, polygon projection and nut polygon
Shape shrinkage pool shapes and sizes are adapted to, and polygon projection can insert the shrinkage pool of nut smoothly；Described torsion haircut is connected with threaded portion
Place is provided with torsion and cuts breach, and junction is inverted cone.
The utility model provides the benefit that: bolt is in rundown process, when moment of torsion exceedes determination value, turns round haircut from screw rod
Tip breakages falls, and ensure that the appropriate level screwing, and keeps bolt end surfacing.After turning round haircut fracture simultaneously
Bolt, can continue to reuse, simply lose the function guaranteeing torque range.

1. nut, 2. screw rod, 3. threaded portion, 4. turn round haircut, 5. shrinkage pool, 6. turn round and cut breach.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the utility model is described in further detail:
Embodiment 1
As shown in Figure 1, 2, 3, a kind of hexagonal torsional shear type bolt, including haircut the 4th, shrinkage pool is turned round in nut the 1st, screw rod the 2nd, threaded portion the 3rd,
5th, breach 6 is cut in torsion, and the center line of above-mentioned six features is arranged on the same line；
Described nut 1 one end is connected with screw rod 2, and nut 1 other end is provided with polygon shrinkage pool 5；
The major part of described screw rod 2 is provided with screw thread, forms threaded portion 3；
Described threaded portion 3 end is connected to torsion haircut 4, and turning round haircut 4 in the present embodiment is to wait hexagon projection, waits hexagon
The polygon shrinkage pool 5 shapes and sizes adaptation of projection and nut 1, turns round haircut 4 and can insert the shrinkage pool 5 of nut 1 smoothly；Described torsion
Haircut 4 and junction, threaded portion 3 are provided with torsion and cut breach 6, and junction is inverted cone.Turn round and cut the degree of depth of breach 6 and determine torsion and cut
The yield strengths of 4 fractures, the size according to required torque can arrange multiple torsional shear type bolts of seriation.
In use, a bolt of the present utility model is turned round the shrinkage pool 5 that haircut 4 is placed in another bolt to be screwed
In, another bolt to be screwed can be a kind of hexagonal torsional shear type bolt that the utility model is introduced, it is also possible to use interior hexagonal
Standard component bolt.Rotate torsion haircut 4 with interior hexagonal specific purpose tool by the shrinkage pool 5 of a kind of hexagonal torsional shear type bolt, screw and wait to revolve
Another tight bolt, when screwing moment of torsion and exceed certain value, torsion haircut 4 of the present utility model from threaded portion 3 tip breakages, this
Sample allows for bolt to be screwed and is in and suitably screws under power.
The present embodiment is only to further illustrate to of the present utility model, and is not a kind of restriction, all according to this patent
Technical scheme makees equivalent transformation, for example, grade hexagon is converted to quadrangle or other N limit shapes etc., each falls within the protection of this patent
Scope.
