[0002] In the structural design of electronic products, it is often necessary to fix structural parts on the PCB, such as screen brackets on the PCB, light guides on the PCB, acoustic structural parts on the PCB, etc. At present, the commonly used solution is screw fixation. Screw fixation of structural parts mainly involves screwing from the back of the PCB. Because there is no pre-fixed structure, screwing from the back is difficult and often requires additional tooling for fixation, which increases the difficulty of the work. Summary of the Invention

[0004] The purpose of the utility model is achieved through the following technical measures: a structural part on a PCB, including a structural part body, the bottom of the structural part body is provided with a buckle along one of the diagonal directions, and a column is provided along the other diagonal direction, a screw hole is provided in the inner center of the column, and a screw positioning column is provided next to one of the columns.

[0005] As a further improvement of the above technical solution:

[0006] The buckle comprises a positioning column and a deformable buckle portion, and there is a gap between the positioning column and the deformable buckle portion.

[0007] The upper end portion of the deformable buckle portion is provided with a vertically arranged boss.

[0008] The bottom of the boss is a plane, and the side of the boss has a chamfer.

[0009] The corresponding surfaces of the positioning column and the deformable buckle portion are both flat surfaces.

[0010] The sides of the positioning post and the deformable buckle portion away from the gap are both arc-shaped surfaces, and the arc-shaped surface of the positioning post and the arc-shaped surface of the deformable buckle portion are on the same circumference.

[0011] Due to the adoption of the above technical solution, the advantages of the present invention compared with the prior art are: the present invention can pre-fix the structural part, ensure reliable positioning, facilitate screwing, and reduce the difficulty of work; during assembly, the positioning column is guided in the first through hole, and at the same time, the deformable buckle portion is deformed toward the positioning column; after assembly, the deformable buckle portion rebounds and clamps the PCB, and the diagonal distribution realizes the positioning of the structural part body; the screw positioning column enters the second through hole, and the screw passes through the third through hole and is threadedly connected to the screw hole on the column, thereby fixing the structural part.

[0022] like Figure 1-5 As shown, a structural component on a PCB includes a structural component body 1, and a buckle 2 is provided at the bottom of the structural component body 1 along one of the diagonal directions. The buckle 2 includes a positioning column 3 and a deformable buckle portion 4. The deformable buckle portion 4 is elastic and can be deformed. The corresponding surfaces of the positioning column 3 and the deformable buckle portion 4 are both flat. There is a gap 5 between the positioning column 3 and the deformable buckle portion 4. The surfaces of the positioning column 3 and the deformable buckle portion 4 away from the gap 5 are both arc-shaped surfaces. The arc-shaped surface of the positioning column 3 and the arc-shaped surface of the deformable buckle portion 4 are on the same circumference. The upper end of the deformable buckle portion 4 is provided with a vertically arranged boss 6, the bottom of the boss 6 is flat, and the side of the boss 6 has a chamfer 15.

[0023] The bottom of the structural body 1 is provided with columns 7 along another diagonal direction, and the inner center of the column 7 is provided with a screw hole 8. A screw positioning column 9 is provided next to one of the columns 7, and the PCB 14 is provided with a first through hole 10 for the buckle 2 to pass through, a second through hole 11 for the screw positioning column 9 to pass through, and a third through hole 12 for the screw 13 to pass through.
