Description

Technical Field

[0001] The utility model belongs to the technical field of voice broadcast terminals, and particularly relates to a voice broadcast terminal convenient for installation. Background Art

[0002] When installing a voice broadcast terminal, it is often installed on the installation surface by means of screw fixation, welding or glue bonding. The traditional screw fixation method usually requires tools such as screwdrivers and wrenches to tighten the screws. The installation process is relatively cumbersome, and during the tightening process, the installation panel may be damaged or fixed unstably due to improper force control. Welding fixation usually requires equipment such as a welding machine, with relatively high operation technical requirements. And once the welding is completed, if replacement or movement is needed, the original welding points may need to be damaged, which is not flexible enough. Using glue or other adhesives for fixation is a simple and quick fixation method, but it may not be applicable to all materials, and it may not be stable enough in an environment with vibration or temperature changes, and may age and fall off over time.

[0003] Fixation methods such as hooks and buckles have emerged. They may require multiple components to be used in cooperation, and the installation process may be relatively complex, and they may not be reliable enough in an environment with large forces or vibrations. Elastic pins such as spring pins can provide a certain fixing and connecting function, but they may not be convenient enough in occasions that require frequent disassembly, and there may be a risk of falling off.
