Abstract
The invention discloses an anti-theft and falling-resistant screw which comprises a first nut, a first threaded rod, a second threaded rod and a second nut. A through hole is formed in the first nut; a first inner thread is arranged in the through hole; a first outer thread matched with the first inner thread is arranged at the upper end of the first threaded rod; the first nut is movably connected with the first threaded rod through the first inner thread and the first outer thread; the second threaded rod is fixedly connected with the second nut; a protrusion is arranged on the lower portion of the first threaded rod; a second outer thread is arranged on the outer wall of the protrusion; a groove is formed in the upper portion of the second threaded rod; a second inner thread matched with the second outer thread is arranged inside the groove. In this way, the first threaded rod and the second threaded rod can be effectively prevented from getting loose through the anti-theft and falling-resistant screw, the falling-resistant performance is good, the anti-theft performance of the whole screw is improved, and the anti-theft effect and using effect are good.
Description
Technical field
The present invention relates to five metals manufacture field, particularly relate to a kind of antitheft resistance to fall screw.
Background technique
Existing resistance to fall screw be make special engineering resin be permanently adhered on thread with special technique, screw bolt and nut is made to reach the absolute resistance to vibrations and impact by extruding in locking process, thus play the problem preventing loosened screw, existing resistance to fall screw be all the connection mode that nut is connected with screw rod, do not have antitheft effect.
Summary of the invention
The technical problem that the present invention mainly solves be to provide a kind of resistance to fall better, the theftproof performance of performance better antitheft resistance to fall screw.
For solving the problems of the technologies described above, the invention provides a kind of antitheft resistance to fall screw, comprise: the first nut, first screw rod, second screw rod and the second nut, described first nut is provided with a through hole, the first internal thread is provided with in described through hole, the upper end of described first screw rod is provided with the first outside thread matched with described first internal thread, described first nut is flexibly connected by the first internal thread and the first outside thread with described first screw rod, described second screw rod is fixedly connected with described second nut, the bottom of described first screw rod is provided with a projection, the outer wall of described projection is provided with the second outside thread, the top of described second screw rod is provided with a cell body, the second internal thread matched with described second outside thread is provided with in described cell body.
In a preferred embodiment of the present invention, the outer wall of described first screw rod is coated with the first engineering resin.
In a preferred embodiment of the present invention, the outer wall of described second screw rod is coated with the second engineering resin.
In a preferred embodiment of the present invention, the height of described first engineering resin is more than or equal to the height of described second engineering resin.
In a preferred embodiment of the present invention, described first screw rod is identical with the external diameter of described second screw rod.
The invention has the beneficial effects as follows: the present invention antitheft resistance to fall screw effectively can prevent loosening of the first screw rod and the second screw rod, resistance to fall performance good, improve the theftproof performance of whole screw, good anti-theft effect, using effect is good.
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 be of the present invention antitheft resistance to fall the structural representation of screw one 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 antitheft resistance to fall screw, comprise: the first nut 1, first screw rod 2, second screw rod 3 and the second nut 4, described first nut 1 is provided with a through hole 11, the first internal thread is provided with in described through hole 11, the upper end of described first screw rod 2 is provided with the first outside thread 21 matched with described first internal thread, described first nut 1 is flexibly connected by the first internal thread and the first outside thread 21 with described first screw rod 2, described second screw rod 3 is fixedly connected with described second nut 4, the bottom of described first screw rod 2 is provided with a projection, the outer wall of described projection is provided with the second outside thread 22, the top of described second screw rod 3 is provided with a cell body, the second internal thread 31 matched with described second outside thread 22 is provided with in described cell body.
By the cooperation of the first outside thread 22 and the first internal thread, first nut 1 is fixedly connected with the first screw rod 2, by the cooperation of the second outside thread 22 and the second internal thread 31, first screw rod 2 is fixedly connected with the second screw rod 3, described second screw rod 3 is fixedly connected with described second nut 4, therefore, whole screw anti-theft is effective, easy to use.
The outer wall of described first screw rod 2 is coated with the first engineering resin 5.First engineering resin 5 effectively can prevent loosening of the first screw rod 2, uses the better effects if of screw.
The outer wall of described second screw rod 3 is coated with the second engineering resin 6.Second engineering resin 6 effectively can prevent loosening of the second screw rod 3, uses the better effects if of screw.
The height of described first engineering resin 5 is more than or equal to the height of described second engineering resin 6.
Described first screw rod is identical with the external diameter of described second screw rod.
Be different from prior art, the present invention antitheft resistance to fall screw effectively can prevent loosening of the first screw rod and the second screw rod, resistance to fall performance good, improve the theftproof performance of whole screw, good anti-theft effect, using effect is good.
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.
