Description

Technical Field

[0001] The utility model relates to the technical field of laser projection equipment, and more specifically, to a laser projection equipment. Background Art

[0002] In the existing technology, laser projection equipment, as an advanced display technology, is widely used in home theaters, business presentations, education and other fields. However, the existing laser projection equipment has certain limitations in fixing and connecting, which limits its convenience and flexibility.

[0003] Specifically, existing laser projection equipment often needs to rely on complex mounting brackets or hoisting systems for fixed installation. These installation methods usually require professional technicians to operate, involving precise adjustment of the projection equipment and modification of the installation environment. During the installation process, it may be necessary to drill holes and screw in the wall or ceiling, which not only increases the complexity of the installation, but may also damage the interior decoration. In addition, the installed projection equipment is often difficult to adjust the position. Once fixed, its position and angle are difficult to change, which brings inconvenience to the user's flexible adjustment during use.

[0004] On the other hand, existing laser projection equipment also has problems when connecting to external devices. Many projection devices need to be connected to external devices such as computers, game consoles, audio systems, etc. through a series of cables and interfaces. These connection processes can be cumbersome and prone to errors, especially for non-professionals. Moreover, the layout and hiding of cables is also a challenge. Too many cables not only affect the aesthetics of the interior, but also may cause safety hazards such as tripping. Utility Model Content
