Please refer to the third to fourth figure. The anti-loose screw structure is mainly used in the field of assembling solar panels 101, photovoltaic modules or greenhouse engineering equipment. The anti-loose screw structure has a screw 10 and a nut 20 The nut 20 has an inner screw hole 21, and the screw 10 includes a head portion 11, a neck portion 12 and a tooth portion 13 having a rotating portion for holding a rotating tool. 111, extending downwardly from the head portion 11 to form a neck portion 12, the neck portion 12 further extending downward to form a threaded portion 13 formed by a processing machine, wherein the tooth portion 13 has a cusp The end 131 and the flat end 132 are used to guide the screw 10 into the inner screw hole 21 of the nut 20. The cusp end 131 has the same outer diameter as the flat end 132, by the flat The tooth end 132 abuts against the wall surface of the inner screw hole 21 to prevent the screw 10 and the nut 20 from being loosened due to vibration.

The principle of operation of the present invention is actually explained. First, the operator puts the screw 10 into the groove of an aluminum extruded frame strip 102, and holds the head 11 through a rotating tool; the solar panel 101 is mounted on the aluminum extrusion. After the support surface of the frame strip 102, the solar panel is pressed by an upper pressing piece 103, and then locked to the tooth portion 13 of the screw 10 by a nut 20, and the operator screwes the nut 20 through the cusp end 131. The flat end 132 has the same outer diameter of the ridge as the cusp end, so that the flat end 132 has a large contact area, in other words, a larger locking force, and the screw 10 and the nut 20 can be locked together. Therefore, the fixing device 100 of the solar panel 101 is erected outdoors, and it is less likely to be loosened even in the case of vibration.

In the above embodiment, the rotating portion 11 can be a quadrilateral structure and can be slid in the groove of the aluminum extruded frame strip 102; the above-mentioned rotating portion 111 is designed as a quadrilateral shape in the following advantages: (1) adding a head The contact area of the portion 11 with the aluminum extruded frame strip 102, the structure of the fixing device 100 for providing the solar panel 101 is more stable; (2) the conventional screw structure heads are all made into a hexagonal shape, because the contact area is not large, the hexagonal shape The rotating portion may instead expand the groove of the aluminum extruded frame strip 102 to cause deformation. Therefore, another advantage of the rotating portion 111 of the present invention being designed as a quadrilateral is to prevent deformation of the aluminum extruded frame strip 102. Further, the rotating portion may be provided in a quadrangular structure such as a square, a rectangle or a diamond.

Please refer to the third to ninth drawings, which are the way to prevent the loose screw structure from being manufactured, including:

Step 1: The wire 202 is placed in a straightening machine 201 straight.

Step 2: The aforementioned steel wire 202 is placed in the cutter 203 to be quickly cut to form a plurality of steel bars 205.

Step 3: The aforementioned steel strip 205 is placed in a processing machine 204 to form a steel strip 205 structure having a head portion 11.

Step 4: The steel strip 205 having the head portion 11 is arranged through a vibrating mechanism. Then, the steel strip 205 having the head portion 11 is sequentially placed into a mold 206 having a toothed portion 13 formed below the mold 206. The deeper cusp end 131 forms a tamper-proof screw structure.

Considering the durability of the screw 10, the creation manufacturing process further includes a step five: cleaning the surface of the anti-loose screw structure to form a durable anti-loose screw structure.

Through the screw structure manufactured by the above process, the screw can only be locked into the aluminum extruded frame strip 102 through a rotating tool (such as a hand tool or an electric screwdriver), and the flat end 131 abuts against the screw hole 21 in the nut 20. The wall surface cannot overcome the locking force without using the rotating tool, so that the vibration can be overcome and the screw can be prevented from being loosened, so that the fixing device 100 of the solar panel 101 is more stable.
