[0004] Therefore, the utility model aims at providing a convenient installation's PCB board, which solves the problems in the background art.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A convenient installation's PCB board, including PCB board main part, the upper surface four corners of PCB board main part are all provided with square groove, the inside of multiple square grooves is all clamped with square block, the middle part of multiple square blocks is all provided with through hole, the inside of through hole is fixedly provided with positioning pipe, the lower end of positioning pipe extends to the lower of PCB board main part, the inner wall of positioning pipe is provided with internal thread, the end of positioning pipe away from square block is provided with abutting mechanism.

[0007] Preferably, the abutting mechanism includes a tapered pipe and a support pad, the tapered pipe is fixedly arranged at the end of the positioning pipe away from the square block, two support pads are respectively fixedly arranged on the outer walls of the two sides of the tapered pipe, and a strip-shaped groove is formed on the two side surfaces of the tapered block and between the two support pads.

[0008] Preferably, the tapered pipe is made of flexible PVC material.

[0009] Preferably, the inner wall of the positioning pipe is coated with a wear-resistant coating.

[0010] Preferably, the plurality of support pads are rubber pads.

[0011] Preferably, the plurality of square blocks are fixedly bonded to the square grooves by hot melt adhesive.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] This invention achieves initial positioning of the PCB board body by inserting multiple tapered tubes and positioning tubes into corresponding mounting holes. Bolts are then threaded onto the internal threads of the positioning tubes. The lower ends of the bolts gradually move downwards into the tapered tubes. Once inside, the bolts press the two sides of the tapered tubes outwards along the center line of the groove, causing the support pads on both sides of the tapered tubes to move backwards. This results in the support pads pressing tightly against the inner walls of the mounting holes, thus completing the positioning and installation of the PCB board body. Precise hole alignment is not required during this process, significantly improving the installation efficiency of the PCB board body. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] This utility model discloses a PCB board that is easy to install.

[0023] Reference Figures 1-4A convenient PCB board includes a PCB board body 1. Square grooves 8 are formed at the four corners of the upper surface of the PCB board body 1. Multiple square blocks 2 are engaged within the interior of each square groove 8. The multiple square blocks 2 are bonded to the square grooves 8 with hot melt adhesive. Heating the hot melt adhesive allows the square blocks 2 to be removed from the square grooves 8, facilitating replacement when the tapered tube 5 and positioning tube 3 are damaged. A through hole is formed in the center of each of the multiple square blocks 2, and a positioning tube 3 is fixedly installed inside the through hole. The lower end of the positioning tube 3 extends to the bottom of the PCB board body 1. An internal thread 4 is formed on the inner wall of the positioning tube 3. The inner wall of the positioning tube 3 is coated with a wear-resistant coating to improve the wear resistance of the internal thread groove 4, ensuring a stable connection between the internal thread groove 4 and the bolt.

[0024] Reference Figures 1-4 The positioning tube 3 is provided with a clamping mechanism at the end away from the block 2. The clamping mechanism includes a tapered tube 5 and a support pad 6. The tapered tube 5 is fixedly set at the end of the positioning tube 3 away from the block 2. The tapered tube 5 is made of flexible PVC material and can deform smoothly when squeezed by bolts. The two support pads 6 are respectively fixedly set on the outer walls of the two sides of the tapered tube 5. The two sides of the tapered tube 5 and the two support pads 6 are provided with strip grooves 7. The multiple support pads 6 are all rubber pads, so that the support pads 6 can be stably clamped to the inner wall of the mounting hole.

[0025] In this invention, during use, multiple tapered tubes 5 and positioning tubes 3 are inserted into the corresponding mounting holes to complete the initial positioning of the PCB board body 1. Then, bolts are threaded onto the internal threads 4 of the inner wall 3 of the positioning tube. The lower end of the bolt gradually moves downward into the tapered tube 5. After the bolt enters the tapered tube 5, it will press the two sides of the tapered tube 5 outward with the strip groove 7 as the center line. This causes the two sides of the tapered tube 5 to move the support pads 6 on both sides in opposite directions, thereby making the support pads 6 on both sides abut against the inner wall of the mounting hole, thus completing the positioning and installation of the PCB board body 1. During this process, there is no need for precise hole alignment, which can greatly improve the installation efficiency of the PCB board body 1.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
