一种电路板的防尘装置
摘要：
本发明公开了一种电路板的防尘装置，包括电路板安装箱，所述电路板安装箱的底端固定安装有安装架，安装架的顶端固定安装有电路板本体，电路板安装箱的一侧开设有两个出风口，且电路板安装箱靠近出风口的一侧内壁上固定安装有安装壳，安装壳的一侧内壁上固定安装有旋转电机，旋转电机的输出轴固定安装有齿轮，安装壳的两侧内壁上分别滑动安装有竖直设置的第一齿条和第二齿条，第一齿条和第二齿条均与齿轮相啮合，安装壳的顶端与底端均开设有开口，第一齿条和第二齿条分别通过两个开口延伸至安装壳的外部，且第一齿条的顶端固定安装有第一遮挡板。本发明结构巧妙，防尘效果好的同时兼具良好的散热性，电路板使用寿命长。
摘要（英）：

The invention discloses a dust-proof device for circuit boards, which comprises a circuit board installation box. An installation frame is fixedly installed at the bottom of the circuit board installation box. A circuit board body is fixedly installed on the top of the installation frame. The circuit board installation box is provided with two air outlets in one side. An installation shell is fixedly installed on one inner wall of the circuit board installation box near the air outlets. A rotating motor is fixedly installed on one inner wall of the installation shell. A gear is fixedly installed on the output shaft of the rotating motor. A first rack and a second rack which are vertically arranged are installed in a sliding manner on two inner walls of the installation shell. The first rack and second rack are meshed with the gear. The installation shell is provided with openings in the top and bottom respectively. The first rack and the second rack extend to the outside of the installation shell through the two openings respectively. A first shield plate is fixedly installed on the top of the first rack. The dust-proof device for circuit boards has an ingenious structure, has botha good dust-proof effect and good heat dissipation performance, and contributes to long service life of circuit boards.
