Abstract
The invention relates to the technical field of fastening accessories, in particular to a never-loosening self-locking threaded connection structure, which can conveniently perform loosening prevention treatment on a screw body by arranging a plurality of groups of loosening prevention teeth on the screw body, effectively prevent the screw body from loosening after long-term use, improve the fastening effect of the screw body and improve the practicability and reliability; the anti-loosening screw comprises a screw body, wherein multiple groups of anti-loosening teeth are uniformly arranged on the upper surface of a thread on the screw body in an inclined mode.
Description
Technical Field
The invention relates to the technical field of fastening accessories, in particular to a never-loosening self-locking threaded connection structure.
Background
As is well known, the existing threaded connecting piece is directly connected with an object in a threaded manner when in use, and the threaded connecting piece is easy to loosen after being used for a long time due to the smooth surface of the upper thread of the threaded connecting piece, so that the threaded connecting piece cannot be fastened and connected with the object for a long time.
Disclosure of Invention
In order to solve the technical problems, the invention provides the never-loosening self-locking threaded connection structure which is convenient for loosening prevention treatment of the screw body by arranging the plurality of groups of loosening prevention teeth on the screw body, effectively prevents the screw body from loosening after long-term use, improves the fastening effect of the screw body, and improves the practicability and reliability.
The invention relates to a never-loosening self-locking threaded connection structure, which comprises a screw body, wherein a plurality of groups of anti-loosening teeth are uniformly and obliquely arranged on the upper surface of a thread on the screw body, and the oblique directions of the plurality of groups of anti-loosening teeth are opposite to the rotating direction of the thread on the screw body; with the clockwise screw in external object of screw rod body in and fasten the connection to it, multiunit locking tooth and external object internal contact, because the direction of multiunit locking tooth all inclines and with the screw rod body on the screw thread revolve to opposite, multiunit locking tooth can't carry out anticlockwise rotation in external object inside, thereby make the screw rod body can't carry out anticlockwise rotation on external object, and then carry out locking processing to the screw rod body, effectively prevent to take place not hard up phenomenon after the screw rod body uses for a long time, improve the spiral shell dress fastening effect of screw rod body, improve practicality and reliability.
According to the self-locking threaded connection structure which can never loosen, the thread on the screw body is rotated in the positive direction.
The invention relates to a permanent non-loosening self-locking threaded connection structure, wherein the rotation direction of threads on a screw rod body is reverse rotation.
According to the non-loosening self-locking threaded connection structure, the nut is arranged on the screw rod body in a threaded mode, the thread turning direction in the nut is positive rotation, the lower surface of the thread on the nut is uniformly provided with multiple groups of anti-loosening teeth with the same structure in an inclined mode, and the inclined directions of the multiple groups of anti-loosening teeth are opposite to the thread turning direction in the nut.
According to the self-locking threaded connection structure which can never loosen, the nut is arranged on the screw rod body in a threaded mode, the thread turning direction in the nut is in a reverse turning mode, multiple groups of anti-loosening teeth with the same structure are evenly arranged on the lower surface of the thread on the nut in an inclined mode, and the inclined directions of the multiple groups of anti-loosening teeth are opposite to the thread turning direction in the nut.
Compared with the prior art, the invention has the beneficial effects that: with the clockwise screw in external object of screw rod body in and fasten the connection to it, multiunit locking tooth and external object internal contact, because the direction of multiunit locking tooth all inclines and with the screw rod body on the screw thread revolve to opposite, multiunit locking tooth can't carry out anticlockwise rotation in external object inside, thereby make the screw rod body can't carry out anticlockwise rotation on external object, and then carry out locking processing to the screw rod body, effectively prevent to take place not hard up phenomenon after the screw rod body uses for a long time, improve the spiral shell dress fastening effect of screw rod body, improve practicality and reliability.

FIG. 2 is a partially enlarged schematic view of the screw body of FIG. 1;
FIG. 3 is a schematic view of the screw body of the present invention in a reverse rotation state;
in the drawings, the reference numbers: 1. a screw body; 2. anti-loosening teeth; 3. and a nut.
Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
As shown in fig. 1 to 3, in the never-loosening self-locking threaded connection structure of the invention, during operation, the screw body 1 is screwed into an external object clockwise and fastened, the multiple sets of anti-loosening teeth 2 are in contact with the internal part of the external object, because the multiple sets of anti-loosening teeth 2 are inclined in directions opposite to the screwing direction of the threads on the screw body 1, the multiple sets of anti-loosening teeth 2 cannot rotate anticlockwise in the external object, so that the screw body 1 cannot rotate anticlockwise on the external object, and further the screw body 1 is subjected to anti-loosening treatment, thereby effectively preventing the loosening phenomenon after the screw body 1 is used for a long time, improving the screwing fastening effect of the screw body 1, and meanwhile, by arranging the nut 3 which is matched with the screw body 1 for use, effectively enhancing the anti-loosening effect of the screw body 1 and the nut 3, and improving the practicability and reliability.
According to the never-loosening self-locking threaded connection structure, according to actual requirements, a plurality of groups of anti-loosening teeth can be obliquely arranged on the lower surface of the thread on the screw body, the oblique directions of the plurality of groups of anti-loosening teeth are opposite to the rotating direction of the thread, and the anti-loosening self-locking threaded connection structure can also be matched with a nut of a corresponding structure for use.
The mounting mode, the connecting mode or the setting mode of the self-locking threaded connection structure which can never loosen is a common mechanical mode, and the self-locking threaded connection structure can be implemented as long as the beneficial effects of the self-locking threaded connection structure can be achieved.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
