Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a rigid circuit board. Background Technique

[0002] On a rigid circuit board, a non-conductive substrate can enhance the strength of the board and endow it with strength and stiffness. The rigid circuit board provides good support for components and good thermal resistance.

[0003] During the assembly of the circuit board, ideally, there is no deviation in the position between the circuit board and the reserved mounting seat on the mounting surface, and the assembly can be carried out smoothly. However, due to manufacturing errors, the accuracy of the circuit board can be controlled, but the manufacturing accuracy of the mounting base surface cannot be well controlled. As a result, during the installation process, there is a position deviation between the mounting holes on the circuit board and the reserved holes on the mounting base surface, making the circuit board not firmly fixed and prone to damage.

[0004] Therefore, we propose a rigid circuit board to solve the existing problems. Content of the Utility Model

[0005] The purpose of the utility model is to propose a rigid circuit board for the problems existing in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a rigid circuit board, including a board body and a sleeve. An installation hole is provided on the board body. The sleeve is rotatably arranged in the installation hole. An upper ring is provided at the upper end of the sleeve. A slider is movably arranged in the upper ring through a driving component. An installation bolt is movably inserted on the slider.

[0007] Preferably, a lower ring is provided at the lower end of the sleeve. The upper ring and the lower ring respectively contact the upper and lower surfaces of the board body.

[0008] Preferably, the driving component is composed of a screw rod, a slider and a cap block. The screw rod is rotatably installed in the upper ring. The slider is threadedly installed on the screw rod.

[0009] Preferably, the cap block is fixed at one end of the screw rod protruding from the upper ring, and a notch is provided on the upper ring. The inner diameter of the notch is larger than the diameter of the cap block.

[0010] Preferably, a through hole adapted to the installation bolt is provided on the slider. The installation bolt is movably inserted on the through hole.

[0011] Preferably, there are four installation holes in total, and the positions of the four installation holes are arranged in a rectangular array on the board body.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] During the use of the rigid circuit board of the present utility model, mounting hole structures with large inner diameters can be opened at the four corner positions of the rigid circuit board body, and various sleeve structures can be rotatably arranged on the mounting holes;

[0014] During the actual installation process, when there is a deviation between the position of the mounting bolt and the position of the reserved hole on the mounting base surface, the mounting bolt can be manually straightened to prevent deflection, and then the screw is manually rotated. Under the principle of the lead screw, the slider can drive the mounting bolt to move on the screw, thereby changing the position of the mounting bolt in the sleeve;

[0015] Meanwhile, during this process, the sleeve can be manually rotated to make the sleeve rotate in the mounting hole, thereby further adjusting the position and orientation of the mounting bolt until the position of the mounting bolt is aligned with the position of the reserved hole on the mounting base surface. Finally, the mounting bolt can be screwed into the reserved hole on the mounting base surface;

[0016] In the present utility model, through the cooperation of mechanical structures, the position of the mounting bolt can be adjusted within a small range on the rigid circuit board, thereby eliminating installation errors. Brief Description of the Drawings
