Abstract

The utility model discloses an anti-loosening locking thread screw relates to screw thread design field, including the screw rod body, first screw thread section has been seted up to the week side of screw rod body, the screw thread of first screw thread section has at least one orientation the bending of nut direction, this anti-loosening locking thread screw have realized that the fix with screw is in the metal sheet, especially fixed sheet metal prevents circling round, the inseparable locking of locking moving.

Description

Locking thread screw takes off

Technical Field

The utility model relates to a screw thread design field specifically is an anti-loosening locking thread screw.

Background

At present, when a steel structure enclosing product, a photovoltaic support, a metal structure, a metal shelf plate and a pedestrian floor are fixedly connected through a screw for a building, if a force application part is weak, a bolt is installed, the drawing force is insufficient, and in long-term application, particularly in the vibration process of structure use, the screw is easy to convolute and is pulled out, and even leads to complete loosening and failure.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an anti-loosening locking thread screw technique to solve current similar fastening product when using with sheet metal, the pulling force or the screw-out undersize lead to the problem that the fastening product became invalid.

In order to achieve the above object, the present invention provides the following technical solutions: including the screw rod body, first screw thread section has been seted up to the week side of screw rod body, the screw thread of first screw thread section has at least one orientation the bending of nut direction.

Preferably, the curved portion is a circular arc convex thread.

Preferably, the curved portion is a triangular convex thread.

Preferably, a second thread section is arranged on the peripheral side of the screw body, and the second thread section is a frosted surface.

Compared with the prior art, the utility model provides a pair of locking screw thread takes off, this product is because its adoption is the screw thread of protruding shapes such as lightning triangle-shaped or circular-arc, ensures the product installation back, in long-term application, is difficult for circling round and leads to the pine to take off to can great degree improve mechanical application performance.

Drawings

In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings needed to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments described in the present invention, and other drawings can be obtained by those skilled in the art according to these drawings.

Fig. 1 is a schematic view of an overall structure provided by an embodiment of the present invention.

Fig. 2 is a schematic view of an overall structure according to another embodiment of the present invention.

Description of reference numerals: 1. a screw body; 2. a first thread segment; 3. a second thread segment.

Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

Referring to fig. 2, an embodiment of the present invention provides an anti-loose locking threaded screw, including a screw body 1, a first thread section 2 is disposed on a peripheral side of the screw body 1, threads of the first thread section 2 have at least one bend facing a nut direction, and the number of the bends in each turn is at least one.

In one embodiment, the curved portion is a rounded convex thread.

In another embodiment, the curved portion is a triangular convex thread.

In another embodiment, the circumference of the screw body 1 is provided with a second thread section 3, and the second thread section 3 is a frosted surface.

The curved portion is a triangular raised thread which increases the stress between the thread and the product, thereby increasing the mechanical application performance.

During the use, use electric screwdriver with the rotatory nail of the spiral shell tail end of screw rod body in having the object of pre-forming the hole, the third screw thread on the screw rod body drives the screw rod body and gets into in the product, until the screw rod body bores in pre-forming completely can, when the product produces vibrations or drags, the frosting of second screw section or the flexion of first screw section increase and draw atress and reverse friction, avoid screw rod body reverse rotation, produce not hard up.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
