Description

Technical Field

[0001] The utility model relates to the technical field of support rod connection, in particular to a support rod connection structure. Background Art

[0002] Currently, projection screens are divided into hard screens and soft screens, and there are several different ways to install the two. Taking the hard screen of a 100-inch anti-glare screen as an example, the hard screen is directly bonded to a flat honeycomb aluminum plate or other metal plate, and the whole is packaged and shipped. This structure is inconvenient to transport and install. For example, it is difficult to use elevators to transport in high-rise residential buildings. Taking the soft screen of a hot-melt PVC screen as an example, one way is to install a lifting reel directly on the screen and hang the soft screen, but the flatness of the screen cannot be guaranteed when using this installation method.

[0003] During installation and use, the existing support rod connection is easy to slip because the support rod is not mechanically fixed, causing the curtain frame to deform during installation and use, and the curtain to wrinkle, affecting the customer experience; since the support rod is not easy to install and disassemble, it has a certain adverse effect on people's use process, which also affects the customer experience. In order to solve the shortcomings of the existing technology, we propose a support rod connection structure. Utility Model Content
