Signal generator having protection function and convenient to clean and capable of performing ventilation and heat dissipation

Abstract

The invention relates to a signal generator having a protection function and convenient to clean and capable of performing ventilation and heat dissipation. The signal generator comprises a main body;a protection mechanism is arranged on the main body; a ventilation mechanism is arranged at two sides of the main body; the ventilation mechanism comprises a ventilation hole, an installation plate,a ventilation plate and two fixed components; the fixed component comprises a fixed ring, an insertion rod, a movable plate, a pull line, a fixed plate, a pull ring, two springs and two pull hooks; the protection mechanism comprises a protection plate, a rotary component and two protection components; and the protection component comprises a lateral plate, an insertion ring, a threaded pipe, a screw and a rotary rod. According to the signal generator having the protection function and convenient to clean and capable of performing ventilation and heat dissipation disclosed by the invention, heat dissipation and cooling can be conveniently carried out through the ventilation mechanism; the insertion rod is inserted into or separated from the fixed ring, so that the ventilation plate is assembled and disassembled conveniently; the ventilation plate is conveniently cleaned; furthermore, a display screen and a control key on the main body are isolated from the outside through the protectionmechanism; damage can be prevented; and thus, the protection function of the signal generator is realized.

AI Technical Summary

Problems solved by technology

[0003] In order to facilitate the ventilation and heat dissipation inside the signal generator and make the circuit components in the signal generator work at a suitable ambient temperature, the signal generator is usually equipped with cooling holes for ventilation, but after long-term operation, the cooling holes are easy to accumulate Dust blocks the heat dissipation holes, resulting in poor air circulation inside the signal generator, thereby reducing the heat dissipation performance of the device. Not only that, the display screen and control buttons on the signal generator are directly set outside, although it is convenient for observation and operation. However, at the same time, the display screen and control buttons are exposed and easily damaged by extrusion or other sharp objects during use or transportation, thereby reducing the practicability of the existing signal generator
