Abstract
The patent of the utility model relates to a bolt, including bolt head, screw rod and screw, bolt head and screw rod connect into a whole, and terminal surface one side that the bolt head was kept away from to the screw rod has a round platform type shrinkage pool and a screw hole, and the screw has threaded rod, round platform type boss and interior hexagonal bolt head, cooperatees with the bolt screw rod. Bolt screws up the back, carries out threaded connection with screw and bolt screw rod for that section screw rod that bolt kept away from the bolt head slightly expands, thereby reaches locking purpose.
Description
Technical field
The utility model relates to technical field of fastening, is specifically related to a kind of bolt.
Background technique
Bolt, by bolt head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, needs and nut screw connection, for being fastenedly connected two parts with through hole.This Connecting format is called that bolt connects.As nut is screwed off from bolt, can make again these two parts separately, therefore bolt connection belongs to removably connect.
And when bolt be connected to be given a shock for a long time time, there will be loosening between nuts and bolt, thus cause nut and bolt falling, the nut that prevents that the screw rod that some bolt adopts in the market inserts latch and so near the position of bottom comes off, but this just causes latch easily to be lost, and each installation all needs first to be taken off by latch, extremely bothers.
Bolt coordinates with the tapped hole on nut or machine the effect played and be connected fastening component usually.In practical application, occur sometimes using nut to coordinate with bolt and tapped hole on machine falls short of and cannot ensure the locking situation of bolt.
Model utility content
The technical problems to be solved in the utility model is, provides a kind of owing to still can prevent the bolt loosened when the tapped hole on machine falls short of and nut cannot be used to coordinate with bolt.
Technical solution of the present utility model is, there is provided a kind of bolt with following structure: comprise bolt head, screw rod and screw, the top of described screw rod is fixedly connected with bolt head, screw is connected with screw flight, and screw rod has hole away from the end face of bolt head, and screw has boss, bolt head is hexagonal structure, the hole of screw rod is followed successively by tapped hole, round platform nibs from screw rod end face, and screw has truncated cone shape boss, and the truncated cone shape boss of screw is larger than the round platform nibs of described screw rod.
After adopting above structure, compared with prior art, the utility model bolt has the following advantages: when after screwing bolts, by screw precession screw rod, now because the truncated cone shape boss of screw is a bit larger tham the round platform nibs of screw rod, produce extruding, screw rod produces deformation, slight expansion, and the elastic force utilizing screw expansion to bring prevents loosening of bolt, therefore, the utility model bolt tapped hole tried out on machine falls short of and nut cannot be used to loosen with the bolt under the occasion such as bolt coordinates.
Accompanying drawing explanation
Fig. 1 is that the master of the utility model bolt looks sectional structure schematic diagram.
Fig. 2 is the perspective view of the utility model bolt.
Embodiment
Below in conjunction with specific embodiment, the utility model is further described, but does not limit the invention to these and specifically implement to be described further the utility model bolt below in conjunction with the drawings and specific embodiments:
As depicted in figs. 1 and 2, in this embodiment, the utility model bolt comprises bolt head 1, screw rod 2 and screw 7, bolt head 1 and screw rod 2 connect into an entirety, screw 7 is threaded with screw rod 2, wherein, screw rod 2 has round platform nibs 4 and tapped hole 3 away from the end face of bolt head 1 side, and screw 7 has slightly large truncated cone shape boss 6.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
