Abstract
An anti-slipping bolt comprises a bolt head portion 1, a screw 3 and an oblique cone section 2 located at the upper end of the screw 3. The anti-slipping bolt is characterized in that the oblique cone section 2 is arranged between the bolt head portion 1 and the screw 3, the obliquity of the oblique cone section 2 is 2 degrees-3 degrees. Due to the fact that the oblique cone section 2 with the 2 degrees-3 degrees obliquity is arranged between the bolt head portion 1 and the screw 3, in the process that the bolt is fastened, the screw 3 can be prevented from over-deeply entering a blind hole of a part through the oblique cone section 2, excessive torsion can be effectively avoided, and therefore the bolt is prevented from slipping.
Description
Technical field
The utility model relates to a kind of bolt, relates in particular to a kind of anti-slip thread bolt.
Background technique
Bolt is a kind of very common connected element, is mainly used in fastening between the various parts mechanically.The fastening piece that connects with bolt, nut on the automobile is a lot, should guarantee that it has enough pretightening forces, but can not overtorquing.If overtorquing will make link produce permanent deformation under the effect of external force on the one hand; To make on the other hand bolt produce tensile set, pretightening force descends on the contrary, even causes slide fastener or the phenomenon that fractures.This defective that prior art exists is worth on the expensive equipment at some may bring very huge loss, therefore, solve this defective and will just seem very important.
Summary of the invention
The purpose of this utility model is to address the above problem, and a kind of anti-slip thread bolt is provided, and the utility model is to be achieved through the following technical solutions:
A kind of anti-slip thread bolt comprises bolt head and screw rod, and the oblique conical section that is positioned at the screw rod upper end, and it is characterized in that: be provided with oblique conical section between described bolt head and the screw rod, the gradient of described oblique conical section is 2～3 °.
The beneficial effects of the utility model are: be 2～3 ° oblique conical section owing to be provided with gradient between bolt head and screw rod, effectively avoid the excessive bolt stripped thread that causes of torsion in the process of clamping bolt.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1-bolt head, 2-oblique conical section, 3-screw rod.
Embodiment
The utility model is described in further detail in conjunction with Fig. 1:
A kind of anti-slip thread bolt comprises bolt head 1 and screw rod 3, and the oblique conical section 2 that is positioned at screw rod 3 upper ends, it is characterized in that: be provided with oblique conical section 2 between described bolt head 1 and the screw rod 3, the gradient of described oblique conical section 2 is 2～3 °.Be 2～3 ° oblique conical section 2 owing to be provided with gradient between bolt head 1 and screw rod 3, in the process of bolton, oblique conical section 2 can be avoided the excessively dark blind hole that enters part of screw rod 3, effectively avoids torsion excessive, thereby has avoided bolt stripped thread to occur.
Claims (1)
