[0002] A signal is a physical quantity that represents a message. For example, an electrical signal can represent different messages through changes in amplitude, frequency, and phase. There are two types of electrical signals: analog signals and digital signals. Signals are tools for carrying messages and are the carriers of messages. According to their actual uses, signals include television signals, radio signals, radar signals, communication signals, etc.; according to their time characteristics, there are deterministic signals and random signals.

[0003] The outer shell of the signal acquisition device generally has ventilation holes for heat dissipation. When the device is not in use, the ventilation holes are exposed to the outside. In this way, dust particles in the external air can easily pass through the ventilation holes into the inside of the shell and accumulate inside, which will affect the operation of the internal electronic devices. Therefore, an electronic signal acquisition device is proposed. Utility Model Content

[0022] Reference Figure 1 and Figure 6 An electronic signal acquisition device comprises a collector box body 1, a fixed block 3, a connecting rod 4, a strip rod 5, a connecting plate 6 and a cover plate 10. The bottom of both sides of the collector box body 1 are symmetrically installed with fixed blocks 3. There are four groups of fixed blocks 3. A connecting rod 4 is installed between every two groups of fixed blocks 3. The connecting rod 4 is symmetrically provided with strip rods 5. The top of the strip rod 5 is slidably connected with the connecting plate 6, and the cover plate 10 is installed on the strip rod 5.

[0023] There are two groups of connecting rods 4, which are installed on both sides of the collector box 1 near the bottom through fixing blocks 3. There are four groups of strip rods 5, which are symmetrically arranged on the connecting rods 4. The bottom of the strip rods 5 is provided with through holes matched with the connecting rods 4. Limit blocks 7 are symmetrically installed on the connecting plate 6. The limit blocks 7 are disengaged when the connecting plate 6 slides on the strip rods 5. The top of the strip rod 5 is provided with a sliding groove matched with the connecting plate 6, and the connecting plate 6 is slidably connected to the connecting plate 6 through the sliding groove.

[0024] A heat dissipation fan 8 is installed on the inner wall of one side of the collector box body 1, and ventilation holes 9 are evenly arranged on the other side of the collector box body 1. The cover plate 10 is installed between the two groups of strip rods 5. A display screen 2 is installed on the front of the collector box body 1. A rubber ring 11 is installed on the side of the cover plate 10 close to the collector box body 1, and the cover plate 10 is located on both sides of the collector box body 1 and fits. The cover plate 10 fits the rubber rings 11 on both sides of the collector box body 1 and is tightly pressed against the collector box body 1, so that the cover plate 10 and the collector box body 1 are sealed, and the heat dissipation fan 8 and the ventilation holes 9 are covered to prevent dust from entering the interior of the collector box body 1;
