[0009] Furthermore, a disassembly and replacement assembly is provided on one side of the PCB board body. The disassembly and replacement assembly includes a copper sheet body, and a slot is provided on the top of the copper sheet body.

[0010] Furthermore, a copper sheet connector is provided at the upper end of the slot, a locking block is connected to the bottom of the copper sheet connector, and screws are inserted into both sides of the interior of the copper sheet body.

[0011] Furthermore, a nut is attached to the surface of the screw.

[0013] 1. In this utility model, when installing the PCB board body, the bottom end of the hand-tightening bolt can be installed and fixed with the threaded hole on the equipment by rotating the hand-tightening bolt. The design of the hand-tightening bolt can also prevent the PCB board body from being damaged due to excessive force.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1 - Figure 3 As shown, this utility model provides a high-strength PCB board that is easy to assemble and disassemble, including a PCB board body 1. Both sides of the PCB board body 1 are provided with easy-to-assemble and disassemble components 2. The easy-to-assemble and disassemble components 2 include mounting holes 201. The inner wall of the mounting holes 201 is provided with a reinforcing structure 205. The top surface of the PCB board body 1 is provided with six sets of sleeves 202. A hand-tightening bolt 203 is inserted into the inside of the sleeve 202. A limit block 204 is fixedly connected to the surface of the hand-tightening bolt 203. The top surface of the PCB board body 1 is provided with a signal shielding layer 4. The inner wall of the sleeve 202 is in contact with the outer surface of the limit block 204. The limit block 204 is cylindrical in shape. The position of the hand-tightening bolt 203 is the same as the position of the threaded hole on the equipment. The reinforcing structure 205 is made of metal.

[0023] The effect achieved in Embodiment 1 is that, when installing the PCB board body 1, the bottom end of the hand-tightening bolt 203 on the PCB board body 1 is first aligned with the threaded hole on the equipment, and then the hand-tightening bolt 203 is rotated clockwise so that the hand-tightening bolt 203 can enter the threaded hole for connection and fixation. The design of the limiting block 204 can prevent the hand-tightening bolt 203 from being lost. When disassembly is required, the hand-tightening bolt 203 is reversed so that the hand-tightening bolt 203 can be removed from the threaded hole of the equipment. There is no need to use the installation function, which is convenient and quick. The reinforcing structure 205 is integrally formed with the PCB board body 1 to disperse stress. The signal shielding layer 4, made of copper foil or conductive polymer coating, can cover critical lines, reduce electrical interference, and reduce signal transmission error rate.

[0024] Example 2, as Figure 1 and Figure 4 As shown, a disassembly and replacement assembly 3 is provided on the outside of one side of the PCB board body 1. The disassembly and replacement assembly 3 includes a copper sheet body 301. A slot 302 is provided on the top of the copper sheet body 301. A copper sheet connector 303 is provided at the upper end of the slot 302. A locking block 304 is connected to the bottom of the copper sheet connector 303. Screws 305 are inserted into both sides of the inside of the copper sheet body 301. Nuts 306 are connected to the surface of the screws 305.

[0025] The effect achieved by embodiment 2 is that when installing the PCB board body 1 in different scenarios, the copper sheet connector 303 can be replaced according to the actual situation. When replacing, the nut 306 can be removed. The nut 306 can be selected whether to install it according to the actual situation. Then, the screw 305 is removed from the locking block 304 of the current copper sheet connector 303. At this time, the locking block 304 of the new copper sheet connector 303 is inserted into the slot 302 and then fixed by the screw 305. This makes it convenient to connect with different devices. For multiple models of products sharing the same PCB substrate, only the copper sheet needs to be replaced to adapt to different specifications, reducing mold and material costs.

[0026] Working principle: When installing the PCB board body 1, the bottom end of the hand-tightening bolt 203 can be fixed to the threaded hole on the equipment by rotating the hand-tightening bolt 203. The design of the hand-tightening bolt 203 can also prevent the PCB board body 1 from being damaged due to excessive force. The design of the hand-tightening bolt 203 inside the sleeve 202 makes disassembly and assembly very convenient, improving the ease of use. When installing the PCB board body 1 in different scenarios, the copper sheet connector 303 can be replaced according to the actual situation to facilitate connection with different equipment. For multiple models of products sharing the same PCB substrate, only the copper sheet needs to be replaced to adapt to different specifications, reducing mold and material costs.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
