Together with the embodiments of the present utility model, they are used to explain the present utility model, and do not constitute a limitation to the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0022] As Figure 1 , Figure 2 and Figure 3 shown, a detachable assembled circuit board proposed by the present utility model includes a circuit board main body 1. Mounting holes 101 are provided at the four corners of the circuit board main body 1. It further includes a splicing component 2 and a mounting component 3. The splicing component 2 is arranged on the front and back sides of the circuit board main body 1. The splicing component 2 includes a splicing block 201 and a splicing groove 203. The splicing block 201 and the splicing groove 203 are connected by plugging and sliding. Mounting components 3 are provided on the mounting holes 101 at the four corners of the circuit board main body 1. The mounting component 3 includes a mounting bolt 301 and a mounting bottom block 304. The mounting bolt 301 is rotatably connected to the mounting hole 101, and the mounting bolt 301 is slidably connected to the mounting bottom block 304.

[0023] As Figure 1 , Figure 3 and Figure 6 shown, the splicing component 2 further includes a sliding plate 205 and a spring 207. A limiting hole 202 is opened on the splicing block 201. A limiting guiding column 204 is fixedly arranged inside the splicing groove 203. The limiting guiding column 204 is slidably connected to the sliding plate 205 and penetrates through the sliding plate 205. Limiting convex blocks 206 are fixedly arranged on both sides of the sliding plate 205. The limiting convex blocks 206 and the limiting holes 202 are movably fitted. The upper end of the spring 207 is fixedly connected to the upper part of the inner side of the splicing groove 203. The lower end of the spring 207 is fixedly connected to the upper part of the sliding plate 205. The spring 207 is sleeved outside the limiting guiding column 204.

[0024] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the mounting component 3 further includes a screw 307. A limiting block 303 is fixedly provided at the lower end of the mounting bolt 301. A sliding groove 305 is formed inside the mounting base block 304. The limiting block 303 and the sliding groove 305 are vertically slidably connected. A sector-shaped limiting groove 306 is formed at the bottom of the sliding groove 305. The limiting block 303 and the limiting groove 306 are radially slidably connected. The screw 307 and the lower end of the mounting base block 304 are threadedly connected for mounting and fixing the mounting base block 304. Limiting plates 302 are fixedly provided at the upper end and the middle of the mounting bolt 301 for restricting the position of the mounting bolt 301 and preventing the sliding of the mounting bolt 301 from affecting the mounting and fixing effect of the circuit board main body 1.

[0025] During specific use, when multiple circuit board main bodies 1 need to be spliced, the splicing block 201 is aligned with the splicing groove 203 and inserted. At this time, the splicing block 201 exerts an upward thrust on the limiting convex block 206, and at the same time drives the sliding plate 205 to move upward against the spring 207. When the limiting convex block 206 reaches above the limiting hole 202, it slides down along the limiting hole 202. At this time, the spring 207 exerts a downward pressure on the sliding plate 205, and the splicing of the connected circuit board main bodies 1 can be quickly completed.

[0026] When the circuit board main body 1 needs to be installed, first use the screw 307 to fix the mounting base block 304 on the mounting base plate. Align the limiting block 303 at the lower end of the mounting bolt 301 with the sliding groove 305 at the upper part of the mounting base block 304 and insert it. When the limiting block 303 reaches the bottom of the sliding groove 305, rotate the mounting bolt 301 to screw the limiting block 303 into the limiting groove 306 to complete the installation of the circuit board main body 1. The mounting base block 304 can be pre-installed to facilitate the subsequent installation of the circuit board main body 1. The installation is convenient and there is no need to install and fix it with the screw 307, avoiding damaging the mounting hole 101 and the circuit board main body 1.

[0027] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the present invention, they should all fall within the protection scope of the present invention.
