Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, wherein like component numbers represent like components. It is obvious that the embodiments to be described below are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

It is also to be understood that the terminology used in the description of the embodiments of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the embodiments of the invention. As used in the description of the embodiments of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

Referring to fig. 1-3, the present invention provides a locking screw, which includes a screw head and a screw tail, wherein the screw head is connected to the screw tail, the screw head includes two surfaces, the screw tail is disposed on one surface of the screw head, and the other surface of the screw head is disposed with a hole. Specifically, a thread structure is arranged on the circumferential side of the tail part of the screw, the locking screw is driven into the screw hole along the thread structure in the screw hole through the thread structure at the tail part of the screw and the thread structure in the screw hole, and the locking screw is stabilized through friction force between threads.

In addition, the center line of the screw tail part and the surface connected with the screw head part are arranged in an acute angle mode, namely, the center line of the screw tail part and the normal line of the surface of the screw head part form an included angle, when the screw tail part drills in along the direction of the screw hole, when the screw head part contacts the aluminum alloy plate, the screw tail part continues to drill in the screw hole, part of the screw head part continues to drill in the aluminum alloy plate until the screw tail part completely enters the aluminum alloy plate, the contact area of the screw hole and the screw is larger than that of the screw tail part, and part of the screw head part is increased (as shown in figure 3), so that the contact area between the anti-loosening screw and the aluminum alloy plate is increased, and loosening is prevented.

The tail part of the screw vertically enters the aluminum alloy plate, when the tail part of the screw completely enters the aluminum alloy plate, the check screw is continuously rotated, so that part of the head part of the check screw is rotated into the aluminum alloy plate, the contact area between the check screw and the aluminum alloy plate is increased, the fastening degree of the check screw is improved, and the situations that the check screw slides and is not tightly clamped on the aluminum alloy plate are avoided; meanwhile, the aluminum material, the aluminum alloy and other materials which are easy to deform are driven into the screw, the surface near the screw can be prevented from deforming, part of the screw head enters the plate, the plate can deform at the position of the screw head, the deformation of the whole plate is reduced, and the integrity of the plate is ensured.

In particular, the angle a between the line of the screw head surface and the centre line of the screw tail is 65-80 deg..

The screw tail comprises a thread ridge, and the angle of the thread ridge is less than or equal to 50 degrees. It can be appreciated that the distance between the threads is reduced, which results in a denser thread and a tighter bite between the screw tail and the screw hole.

The jack is any one of hexagon, straight line type or cross. The jack is used for inserting of screwdriver, through the rotation of screwdriver, makes in the screw afterbody drills into the screw according to the trend of screw thread, and the shape diversification of jack can increase and let its use more convenient, can satisfy the matching use of different screwdrivers, improves the convenient degree that the user used.
