Description

Technical Field

[0001] The utility model relates to the field of signal transmission devices, in particular to a wireless signal transmission device. Background Art

[0002] The wireless signal transmission device is the core equipment for wireless transmission. Its working principle is mainly based on the physical principle of free propagation of electromagnetic radiation. The device converts the signal to be transmitted into electromagnetic waves and radiates them into the air through the antenna. At the receiving end, the device uses the antenna to receive the electromagnetic waves and restores them to the original signal.

[0003] For example, a wireless signal transmission device with application number CN202320834506.7 specifically discloses a base plate, a protective cover is installed on the top of the base plate, a mounting opening is opened in the middle of one end of the protective cover, a clamping hole is opened at the top of the base plate corresponding to the mounting opening, an L-shaped clamping plate is installed inside the clamping hole, and limit blocks are symmetrically arranged on both sides of the top of the base plate inside the protective cover, a "J"-shaped clamping plate is installed between the two symmetrically arranged limit blocks, a limit spring is equidistantly installed on one side of the inner wall of the "J"-shaped clamping plate, and one end of the limit spring is connected to the inner wall of the protective cover.

[0004] The angle of the signal transmitter of the existing wireless signal transmission device cannot be adjusted. Due to the fixed angle, the transmitter may not be able to cover all areas that need to be covered, especially those in the direction of the transmitter's non-optimal transmission angle. This may cause signal blind spots or weak signal areas, affecting the reliability and stability of wireless communication. For this reason, we propose a wireless signal transmission device.
