Abstract
The utility model relates to a connecting part which solves the problem that after repeatedly shocked and extended, the common bolt is easily loosened, and has the advantages of convenient assembly and disassembly, and repeated use. The looseness preventing bolt comprises a nut and a screw rod, wherein a nut looseness preventing ratchet wheel is arranged in the cavity of the nut; a ratchet wheel pressing spring is sheathed on the column body of the nut looseness preventing ratchet wheel; and the screw rod is screwed into one end of the nut and is provided with a screw rod ratchet wheel engaged with nut ratchet wheel gears. The column body of the nut looseness preventing ratchet wheel is a quadrangular or other prisms; the upper end of the column body of the nut looseness preventing ratchet wheel is provided with a disassembling inclined plane; and the ratchet wheel pressing spring is arranged between the upper end of the upper cavity of the nut, and the nut ratchet wheel gears.
Description
One, technical field
The utility model relates to a kind of connected element, is specifically related to a kind of bolt that has been used for connection, fastening effect, is meant a kind of reusable anti-loosening bolt especially.
Two, background technique
Existing plain bolt just is provided with internal and external threads on nut and screw rod, thereby play fastening, interconnect function, if to screw rod repeated stock and stretching, nuts and bolt will become flexible, at the position important to some, that the space is little, often adopt welding or become flexible preventing, but adopt welding or gluing later dismounting is brought inconvenience with mighty bond bonding bolt, and the bolt that disassembles can not reuse, and causes waste.
Three, model utility content
The purpose of this utility model provides a kind of reusable anti-loosening bolt, and existing plain bolt is subjected to repeated stock and the loosening easily problem that stretches to solve, and easy accessibility, and is reusable.
For achieving the above object, the technological scheme that the utility model adopted is:
A kind of reusable anti-loosening bolt comprises nut and screw rod, and it is characterized in that: described nut intracavity is provided with the nut anti-looseness ratchet, is with the ratchet holddown spring on the cylinder of nut anti-looseness ratchet; The end that described screw rod screws in nut is provided with and the intermeshing screw rod hook tooth of nut hook tooth.
The cylinder of above-mentioned nut anti-looseness ratchet is quadrangular or other prism.
The cylinder upper end of above-mentioned nut anti-looseness ratchet is processed with the dismounting inclined-plane.
Above-mentioned ratchet holddown spring is arranged between nut epicoele lower end and the nut hook tooth.
The utility model is a kind of reusable anti-loosening bolt, under the abominable service condition of repeated stock and stretching, can not become flexible, and can be for convenience detach, reuse, with low cost.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein, 1-dismounting socket, 2-nut anti-looseness ratchet, 3-ratchet holddown spring, 4-nut hook tooth, 5-nut, 6-screw rod hook tooth, 7-screw rod.
Five, embodiment:
Referring to Fig. 1, a kind of reusable anti-loosening bolt, comprise nut 5 and screw rod 7, nut 5 is processed with epicoele and cavity of resorption, epicoele is prismatic, cavity of resorption is cylindrical, be provided with the nut anti-looseness ratchet 2 of nut hook tooth 4 in the chamber, the upper end cylinder of nut anti-looseness ratchet 2 is with ratchet holddown spring 3, ratchet holddown spring 3 is collapsible or stretch to realize compressing or loosening between nut 5 epicoele lower ends and nut hook tooth 4, the cylinder body shape of nut anti-looseness ratchet 2 is consistent with cavity shape on the nut, and the cylinder upper end of nut anti-looseness ratchet 2 is processed with the dismounting inclined-plane.Nut 5 epicoeles are processed with dismounting socket 1, and the end that screw rod 7 screws in nut 5 is provided with screw rod hook tooth 6, and screw rod hook tooth 6 can be meshing with each other with nut hook tooth 4 and be in the same place.
Anti-loosening principle of the present utility model is: the upper end cylinder body shape of nut anti-looseness ratchet is identical with cavity shape on the nut and insert among the nut epicoele, in epicoele, can restriction itself rotate, when screw rod 7 screws in nut, after being meshing with each other, nut hook tooth 4 and screw rod hook tooth 6 just can not screw out in the other direction, and under the pressing of ratchet holddown spring 3, realize anti-loosening purpose.
During dismounting, bar type instrument is headed into dismounting socket 1, under the effect on dismounting inclined-plane, nut anti-looseness ratchet 2 moves upward and throws off screw rod hook tooth 6, realizes that nut bolt breaks away from.
