Abstract
The utility model relates to the technical field of fasteners, in particular to a bolt capable of preventing vibration and falling. Including bolt body and nut, the bolt body includes bolt head and shank of bolt, the shank of bolt includes a plurality of threaded rods that lean out the setting, and the interval sets up between every threaded rod, and wholly constitutes cone structure, the diameter at cone structure top and the internal diameter phase-match of nut, and the diameter of cone structure bottom is greater than the internal diameter of nut. The bolt body is simple in structure and low in manufacturing cost, the nut can be firmly fixed on the bolt body by the outward tension of the outward inclined threaded rod without auxiliary fixing of other external parts, and vibration falling can be effectively prevented.
Description
Technical Field
The utility model relates to the technical field of fasteners, in particular to a bolt capable of preventing vibration and falling.
Background
At present, the fixed mode of spare part in the product is mostly for the bolt lock attaches, but along with in transportation and the continuous use, the phenomenon that vibrations pine take off appears in the mode ubiquitous of bolt fastening, and these not hard up bolts can make the connection of product spare part not hard up, cause the serious consequence of product inefficacy or even casualties.
Therefore, a bolt for preventing vibration and falling off is provided for solving the problems.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to a bolt for preventing vibration and falling off, so as to solve the problems mentioned in the background art.
In order to achieve the purpose, the utility model provides the following technical scheme: a bolt capable of preventing vibration and falling comprises a bolt body and a nut, wherein the bolt body comprises a bolt head and a bolt rod, the bolt rod comprises a plurality of threaded rods which are obliquely arranged outwards, the threaded rods are arranged at intervals and integrally form a conical structure, the diameter of the top of the conical structure is matched with the inner diameter of the nut, and the diameter of the bottom of the conical structure is larger than the inner diameter of the nut;
further, the inclined angle of the threaded rod is 3-5 degrees;
further, the outer surface of the cone structure is provided with a thread matched with the nut;
further, the number of the threaded rods is 2 or 4.
Compared with the prior art, the utility model has the beneficial effects that:
the bolt body is simple in structure and low in manufacturing cost, the nut can be firmly fixed on the bolt body by the outward tension of the outward inclined threaded rod without auxiliary fixing of other external parts, and vibration falling can be effectively prevented.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a schematic view of a threaded nut according to the present invention;
in the figure: 1-bolt body, 2-bolt head, 3-bolt rod and 4-threaded rod.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: a bolt capable of preventing vibration and falling comprises a bolt body 1 and a nut, wherein the bolt body 1 comprises a bolt head 2 and a bolt rod 3, the bottom of the bolt head 2 is connected with the top of the bolt rod 3, the bolt rod 3 comprises a plurality of threaded rods 4 which are obliquely arranged outwards, the threaded rods 4 are arranged at intervals and integrally form a cone structure, the diameter of the top of the cone structure is matched with the inner diameter of the nut, the diameter of the bottom of the cone structure is larger than the inner diameter of the nut, the bottom of each threaded rod 4 is pressed inwards to be placed into the nut when the bolt is used, then the nut is screwed upwards to a required position, the nut can be firmly fixed on the bolt body 1 through the outward tension of the threaded rods 4, and the nut cannot fall off even if violent vibration occurs;
further, the inclined angle of the threaded rod 4 is 3-5 degrees;
further, the outer surface of the cone structure is provided with a thread matched with the nut;
further, the number of the threaded rods 4 is 2 or 4.
The bolt body 1 is simple in structure and low in manufacturing cost, the nut can be firmly fixed on the bolt body 1 by the outward tension of the outward inclined threaded rod 4, and the bolt body can be effectively prevented from shaking and falling off without the auxiliary fixation of other external parts.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
