[0024] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1-2 As shown, a screw filling auxiliary protective cover for a PCB board is used for screw filling of a PCB board, comprising a transparent plate body 1, and a limiting structure 2 is arranged around the transparent plate body 1. The limiting structure 2 is detachably connected to the transparent plate body 1, and the limiting structure 2 is used to fix the transparent plate body 1 and the mounting shell of the PCB board, and fix the relative position between the transparent plate body 1 and the PCB board. Through holes 3 are arranged on both sides of the transparent plate body 1 for the convenience of the staff to hold it.

[0026] A plurality of guide holes 4 are provided in the middle of the transparent plate body 1, and a guide tube 5 extending downward is provided in the guide hole 4. The guide tube 5 is detachably installed in the guide hole 4. The guide hole 4 is located directly above the screw hole of the PCB board. The guide tube 5 is used to guide the screw from the guide hole 4 to the screw hole of the PCB board, and the inner diameter of the guide tube 5 is slightly larger than the radius of the screw nut, so that the screw can reach the screw hole conveniently and accurately, thereby simplifying the process.

[0027] The coordinate system of the guide holes 4 on the transparent plate 1 is the same as the coordinate system of the screw holes on the PCB, which is used to match the distribution of the guide holes 4 on the transparent plate 1 with the distribution of the screw holes on the PCB, so that the intervals between adjacent guide holes 4 are the same as the intervals between adjacent screw holes. The distribution of the guide holes 4 includes the respective screw holes on all PCBs, so that a protective cover can be used for the screw installation process of all types of PCBs. In order to better install the screws, the coordinate system scale is marked on the transparent plate 1, and the coordinates are marked around the screw holes of the PCB. The staff only needs to know the coordinates of the screw holes, and then install the guide tube 5 on the wire hole corresponding to the coordinates on the transparent plate 1, and then fix the transparent plate 1 to the PCB to install the bolts.

[0028] like Figure 3 As shown, the top of the guide tube 5 is provided with an outer edge structure 6, and the guide hole 4 is provided with an inner concave structure 7 that fits with the outer edge structure 6, so as to realize the detachable connection between the guide tube 5 and the transparent plate body 1. The lower outer side of the guide tube 5 may be provided with an external thread. When the guide tube 5 is installed in the wire hole, it is fixed by a nut structure 8 at the bottom of the transparent plate body 1 to ensure the stability of the guide tube 5 installed in the transparent plate body 1. The external structure of the guide tube 5 has a uniform size, and a variety of inner diameter sizes of the guide tube 5 are set according to different screw radii to meet the installation guide of screws of different sizes.

[0029] The top of the limiting structure 2 is connected to the transparent plate body 1 by a fastening bolt 9, so that the limiting structure 2 and the transparent plate body 1 are detachably connected. Since the sizes of PCB boards vary, in order to make the present technology applicable to PCB boards of all sizes, the limiting structure 2 needs to be adjustable, such as Figure 4 As shown, one way is that the fastening bolt 9 of the limiting structure 2 passes through the guide hole 4, so that the limiting structure 2 can be detachably fixed to the transparent plate body 1, but in this structure, the distance adjustment of the limiting structure 2 cannot be finely adjusted, and the size can only be adjusted at intervals. Therefore, a movable pressing plate 10 that can move inward is provided on the pressing side of the limiting structure 2, and the movable pressing plate 10 is connected to the limiting structure 2 through the adjusting bolt 11. When in use, the limiting structure 2 is first fixed to the most suitable limiting hole, and then the adjusting bolt 11 is used to press the movable pressing plate 10 against the mounting shell of the PCB board to achieve fine adjustment of the limiting structure 2. Another way is to provide a groove for the fastening bolt 9 to move on the transparent plate body 1, and the fastening bolt 9 moves in the groove to achieve position adjustment of the limiting structure 2.

[0030] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
