Technical Field
The invention relates to the technical field of nuts and screws, in particular to a novel never-falling nut and screw connecting structure.
Background
Nut, screw rod commonly used at present are used for connecting between the mechanical parts and the fixed indispensable important part of device, and bolt, nut fastener are with very convenient, but the nut is connected the back with the screw rod, if be in for a long time under the shock condition, connect easy emergence not hard up, appear the pine and take off, and then cause the incident, consequently, the connection structure of a novel never drop nut and screw rod of present design solves nut, screw rod and connects and take place not hard up problem because of vibrations.
Disclosure of Invention
The invention aims to solve the defects in the prior art and provides a novel connection structure of a nut and a screw which never fall off.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a novel connection structure of nut and screw rod never drops, includes nut, screw rod, still includes the elastic spirochaeta, the outer wall align to grid of elastic spirochaeta is equipped with outer barb, the inner wall align to grid of elastic spirochaeta is equipped with interior barb, the thorn point opposite direction of outer barb and interior barb, be equipped with on the inner wall of nut with elastic spirochaeta complex nut internal thread, be equipped with on the outer wall of screw rod with the outer silk of elastic spirochaeta complex screw rod, the thorn point opposite direction of interior barb and the direction of rotation of nut, the thorn point direction of outer barb is the same with the direction of rotation of nut.
As a further improvement of the invention, the inner thread of the nut is of a semicircular concave structure matched with the elastic spiral body, and the outer thread of the screw is of a semicircular concave structure matched with the elastic spiral body.
As a further improvement of the invention, the section of the elastic spiral body is of a circular structure, the heights of the outer barbs and the inner barbs are equal, and the heights of the outer barbs and the inner barbs are greater than the radius length of the section of the elastic spiral body.
As a further improvement of the invention, the outer barbs and the inner barbs are elastic.
As a further improvement of the invention, the outer barbs and the inner barbs are bored out of the surface of the elastic spiral body.
The invention has the beneficial effects that:
1. when the vibration happens, the nut can only rotate along the outer barb, and the screw rod can only rotate along the inner barb, so that the nut and the screw rod rotate in opposite directions, and the nut and the screw rod generate a locking effect.
2. When vibrations make nut and screw rod rotate the relative displacement that produces when too big, elasticity spiral body can spill in the nut, avoids excessive locking to lead to the screw rod fracture, and is safer.
The nut and the screw rod can rotate in opposite directions when the vibration occurs, so that the nut and the screw rod can generate a locking effect, the nut and the screw rod are not easy to loosen, and the screw rod can be broken due to over locking, so that the nut and the screw rod are safer.

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.
Referring to fig. 1-6, a novel connection structure of a nut and a screw never falling off comprises a nut 1, a screw 6 and an elastic screw 3, wherein outer barbs 4 are uniformly arranged on the outer wall of the elastic screw 3, inner barbs 5 are uniformly arranged on the inner wall of the elastic screw 3, the directions of the outer barbs 4 and the prick tips of the inner barbs 5 are opposite, the outer barbs 4 and the inner barbs 5 are bored out on the surface of the elastic screw 3, a nut inner wire 2 matched with the elastic screw 3 is arranged on the inner wall of the nut 1, a screw outer wire 7 matched with the elastic screw 3 is arranged on the outer wall of the screw 6, the rigidity of the outer barbs 4 and the inner barbs 5 is higher than that of the nut 1 and the screw 6, when the nut 1 and the screw 6 are connected, grooves are formed on the nut inner thread 2 and the screw outer thread 7, the pricking tip direction of the inner barb 5 is opposite to the rotation direction of the nut 1, and the pricking tip direction of the outer barb 4 is the same as the rotation direction of the nut 1.
In the invention, the nut inner wire 2 is in a semicircular concave structure matched with the elastic spiral body 3, and the screw rod outer wire 7 is in a semicircular concave structure matched with the elastic spiral body 3.
The cross-section of elasticity spirochaeta 3 is circular structure, and outer barb 4 and interior barb 5 highly equal, and outer barb 4 and the radius length of the cross-section that highly is greater than elasticity spirochaeta 3 of interior barb 5, and outer barb 4 all has elasticity with interior barb 5, can produce certain deformation for when nut 1 is connected with screw rod 6, the interior silk 2 of nut is connected inseparabler with the outer silk 7 of screw rod, makes nut 1 tighter with the 6 spiro couplings of screw rod.
When the elastic screw body 3 is used, the elastic screw body 3 is screwed into the nut 1, one end of the elastic screw body 3 is propped against the last wire of the inner wire 2 of the nut and then stops, then the nut 1 with the elastic screw body 3 inside is screwed onto the screw rod 6, when vibration occurs, the nut 1 can only rotate along the outer barb 4, the screw rod 6 can only rotate along the inner barb 5, and then the nut 1 and the screw rod 6 rotate in opposite directions, so that the nut 1 and the screw rod 6 generate a locking effect; when the relative displacement generated by the rotation of the nut 1 and the screw 6 is overlarge due to vibration, the elastic screw body 3 can leak out of the nut 1, and the screw 6 is prevented from being broken due to over-locking.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
