Abstract
The invention discloses an anti-loose threaded rod of a vehicle wheel. The threaded rod comprises a first nut, a first threaded rod body, a second threaded rod body, a third threaded rod body and a second nut, the first nut is movably connected to the first threaded rod body, the low end of the first threaded rod body is provided with a kidney-shaped notch and fixedly connected with the upper end of the second threaded rod body, the lower end of the second threaded rod body is fixedly connected with the upper portion of the third threaded rod body, the second threaded rod body is a cylinder, the upper end of the third threaded rod body is provided with one or more splines, and the second nut is movably connected to the third threaded rod body. By means of the anti-loose threaded rod of the vehicle wheel and through the mode, resistance after the anti-loose threaded rod after being stressed is increased through mechanical meshing between the nuts and the threaded rod bodies, thereby by means of the mechanically meshed structure, the anti-loose performance of the threaded rod is substantially improved, the production cost is lowered, and the using effect is better.
Description
Technical field
The present invention relates to wheel anti-loosening screw field, particularly relate to a kind of wheel anti-loosening screw.
Background technique
Anti-loosening screw originates from abroad, existing anti-loosening screw is attached on screw thread so that special engineering plastics are permanent, internal and external threads is made to tighten process, screw rod is extruded and produces powerful reaction force, substantially increase the frictional force between internal and external threads, provide the absolute resistance to vibration, but the anti-loosening screw complex manufacturing technology that this processing technology is made, and fabricating cost is higher.
Summary of the invention
The technical problem that the present invention mainly solves is to provide and a kind ofly makes screw rod have the wheel anti-loosening screw of anti-loosing effect by mechanical engagement.
For solving the problems of the technologies described above, the invention provides a kind of wheel anti-loosening screw, comprise: the first nut, first screw rod, second screw rod, 3rd screw rod and the second nut, described first nut is movably connected on described first screw rod, the lower end of described first screw rod is provided with a waist type breach, the lower end of described first screw rod is fixedly connected with the upper end of described second screw rod, the lower end of described second screw rod is fixedly connected with the top of described 3rd screw rod, described second screw rod is cylindrical body, the upper end of described 3rd screw rod is provided with at least one spline, described second nut is movably connected on described 3rd screw rod.
In a preferred embodiment of the present invention, described wheel anti-loosening screw also comprises the first pad, and described first pad is movably connected in the top of described waist type breach, and is positioned at the below of described first nut.
In a preferred embodiment of the present invention, described wheel anti-loosening screw also comprises the second pad, and described second pad is movably connected in the below of described spline, and is positioned at the top of described 3rd nut.
In a preferred embodiment of the present invention, described spline is four, and described spline circle distribution is on described 3rd screw rod.
The invention has the beneficial effects as follows: the resistance after wheel anti-loosening screw of the present invention is stressed by the mechanical engagement increase anti-loosening screw between nut and screw rod, thus the anti-loosening property of screw rod is increased substantially by the structure of mechanical engagement, reduce cost of production, using effect is better.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of wheel anti-loosening screw one of the present invention preferred embodiment.
Embodiment
Be clearly and completely described to the technological scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of wheel anti-loosening screw, comprise: the first nut 1, first screw rod 2, second screw rod 3, 3rd screw rod 4 and the second nut 5, described first nut 1 is movably connected on described first screw rod 2, the lower end of described first screw rod 2 is provided with a waist type breach 21, the lower end of described first screw rod 2 is fixedly connected with the upper end of described second screw rod 3, the lower end of described second screw rod 3 is fixedly connected with the top of described 3rd screw rod 4, described second screw rod 3 is cylindrical body, the upper end of described 3rd screw rod 4 is provided with at least one spline 41, described second nut 5 is movably connected on described 3rd screw rod 4.
When first nut 1 is fixedly connected with the first screw rod 2, the lower end due to the first screw rod 2 is provided with a waist type breach 21, makes screw rod anti-loosing effect better by this mechanical engagement.Same, the upper end of described 3rd screw rod 4 is provided with at least one spline 41, and described second nut 5 is movably connected on described 3rd screw rod 4, and spline 41 and the second nut 5 are by this mechanical engagement thus make screw rod anti-loosing effect better.
Described wheel anti-loosening screw also comprises the first pad 6, and described first pad 6 is movably connected in the top of described waist type breach 21, and is positioned at the below of described first nut 1.
Described wheel anti-loosening screw also comprises the second pad 7, and described second pad 7 is movably connected in the below of described spline 41, and is positioned at the top of described 3rd nut 5.
Described spline 41 is four, and described spline 41 circle distribution is on described 3rd screw rod 5.
Be different from prior art, resistance after wheel anti-loosening screw of the present invention is stressed by the mechanical engagement increase anti-loosening screw between nut and screw rod, thus the anti-loosening property of screw rod is increased substantially by the structure of mechanical engagement, reduce cost of production, using effect is better.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
