Description

Anti-loose screw forming mold

The present invention relates to a anti-loose screw forming mold, which is mainly used in a screw forming mold used in the field of solar panel, photoelectric engineering or greenhouse equipment engineering, and a cusp end is provided at the bottom end of the mold at five to nine teeth, at the cusp end The upper end has a flat end, and the flat end has a facet, whereby the screw manufactured by the present invention forms a flat end for introducing into a nut, and the flat end of the flat teeth is fastened to the wall surface of the screw hole of the nut. The structure makes the screws and nuts not loose due to vibration and wind blowing.

Please refer to the first and second figures, which are fixing devices (100) of the solar panel (101). The structure is characterized in that the aluminum extruded frame strip (102) is first fixed on a base, and then two or more sets of solar energy are used. The plate (101) fixes the solar panel (101) to the aforementioned aluminum extruded frame strip (102) through screws, nuts and an upper pressing piece (103).

Since the fixing device (100) of the solar panel (101) is installed in an outdoor space, there may be wind, rain, earthquake, etc., which cannot be avoided. It can be understood that when a vibration occurs, the nut will gradually loosen. The solar panel (101) or the photoelectric module may be tilted, the fixing device (100) may be deformed or even cause problems such as collapse of the solar panel (101) fixed module, short circuit, and the like.

In the case of industrial vibration, the object can be tightened by spring washers, adhesives, etc. to prevent the screws from loosening; however, in the field of solar panels (101) or photovoltaic modules, the accuracy and level are required. And when the locking solar panel (101) may cause uneven locking force if the spring washer is used, it may also cause the deformation or collapse of the fixing device (100) of the solar panel (101).

Therefore, in order to solve the above problems, the present invention provides a mold capable of preventing the loosening of a screw, and the screw produced by the same can be fastened in the nut to prevent the solar panel fixing device from collapsing and deforming.

The purpose of the present invention is to provide a anti-loose screw forming mold which is assembled on a screw forming machine, which is provided with a pointed end and a flat end, and the screw is passed through the mold to form a flat tooth segment. The structure has a micro-planar structure, and the screw and the nut are fastened by the plane topping into the inner screw hole of a nut.

The structure that can achieve the above object is a rectangular solid with two shapes symmetrical, which can define a first mold core and a second mold core; and the first mold core and the second mold core Forming on a screw forming machine and forming a forming passage for the material to pass between the first mold core and the second mold core, the first mold core and the second mold core surface are provided with a plurality of tooth grooves, The gullet can define a pointed end and a flat end, and the cussing end is disposed at a bottom edge of the first mold core and the second mold core, and the tooth groove cross section of the flat tooth end is V-shaped, and the flat tooth end The tooth groove of the flat tooth end is arranged in an inverted trapezoidal shape, and the material passes through the forming channel to form a anti-loose screw.

Therefore, according to the technical means of this creation, the brief descriptions of the functions that can be obtained by this creation are as follows: 1. The screw structure manufactured by the creation is mainly provided with a sharp tooth segment, a flat tooth segment, and an assembly person in the tooth portion of the screw. By screwing the screw through a turning tool, it can be screwed tightly into the screw hole of the nut, and then the top of the flat tooth portion is abutted against the wall surface of the screw hole in the nut, and the screw and the nut are not separated even if there is vibration. 2. The tip of the screw provides the inner screw hole of the guide screw to the nut. Then the area of the flat end is slightly larger than the inner screw hole. The more the screw locks into the screw hole of the nut, the greater the locking force. Therefore, the vibration is used. In this case, the nut is not loosened, and the structural strength of the solar panel is improved.

In order to enable your review committee to have a better understanding and recognition of the characteristics and characteristics of the case, the following preferred examples are listed below with the following description:

Referring to Figures 3 to 4, the creation of the anti-loose screw forming mold is a rectangular body of two shapes symmetrical, which can define a first mold core (10) and a second mold core (20); The first mold core (10) and the second mold core (20) are assembled on a screw forming machine and formed between the first mold core (10) and the second mold core (20). Providing a forming passage through which a material passes, the first mold core (10) and the surface of the second mold core (20) are provided with a plurality of tooth grooves (11, 21), and the tooth grooves (11, 21) can define a a cusp end (111, 211) and a flat end (112, 212), the cusp end (111, 211) is disposed at a bottom edge of the first mold core (10) and the second mold core (20), The trough (11, 21) of the flat end (112, 212) has a V-shaped cross section, and the flat end (112, 212) is disposed above the cusp end (111, 211), the flat end ( The slots (11, 21) of 112, 212) are inverted trapezoids, and the material passes through the forming passage to cut out the ridges to form a anti-loose screw.

Please refer to Figures 5 to 8 to illustrate the manufacturing method of a loose-proof screw structure:

Step 1: Place the wire (202) in a straightening machine (201) straight.

Step 2: The aforementioned steel wire (202) is placed in a 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.

Step 4: The steel strip (205) having the head is arranged through a vibration mechanism, and then the steel strip (205) having the head is sequentially placed in the screw forming machine, and the steel strip (205) passes through the first The molding channel between the mold core (10) and the second mold core (20) is relatively linearly moved back and forth between the first mold core (10) and the second mold core (20) in the steel strip (205) The surface of the tooth is pulled out by the first mold core (10) and the second mold core (10) with a deeper tooth end (111, 211), above the pointed end (111, 211) There are pairs of flat ends (112, 212) to form a loose-proof screw structure.

Considering the durability of the screw, the creation manufacturing process further includes a step five: the surface of the anti-loose screw structure is cleaned 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, an electric screwdriver), and the screw hole of the nut is fixed by the flat tooth top. The wall surface cannot overcome the locking force without using the rotating tool, so the vibration can be overcome and the screw can be prevented from loosening, so that the fixing device (100) of the solar panel (101) is more stable.

In summary, the composition of this creation has not been seen in the publications or public use, and it is in line with the requirements of the new patent application, so please ask the Bureau to identify the patent, and grant the patent as soon as possible.
