Description

Technical Field

[0001] This utility model relates to the field of mobile phone holder technology, and in particular to a built-in structure for a dual-center-point rotating bracket. Background Technology

[0002] The main function of a phone stand is to provide stable support and a convenient user experience. The stand can be adjusted in angle and height to help users find the best viewing position, reduce fatigue, and improve the convenience, comfort, and safety of phone use, making it suitable for various scenarios. Dual-center-point rotating stands, with two rotation centers—one for horizontal rotation and the other for vertical rotation—allow for multi-directional adjustment, making their use more flexible. However, most existing dual-center-point rotating stands are one-piece structures, which are difficult to assemble, have high production costs, and make it difficult to replace some parts, affecting the stand's practicality. Furthermore, the stands lack a self-locking mechanism, making it easy for them to unfold on their own due to inertia after folding, impacting the user experience. Therefore, designing an internal structure for dual-center-point rotating stands is essential. Utility Model Content

[0003] The purpose of this invention is to provide a built-in structure for a dual-center-point rotating bracket to address existing defects.

[0011] This utility model provides an internal structure for a dual-center-point rotating bracket, which has the following advantages: A clamping plate connected by a U-shaped bracket rotatably connects the fixing plate to the bottom of the mounting frame, forming the rotational support for the entire structure. The first shaft connects to the connecting ring, forming the rotational support for the first support plate. Simultaneously, the second shaft connects to the second flip plate, forming the rotational structure for the second support plate. The entire structure, along with the circular holes on the fixing plate, can be installed on the dual-center-point rotating bracket. The overall structure is simple, easy to assemble, and has low manufacturing costs. It also facilitates the replacement of some parts, improving the practicality of the bracket. After installation, the fixing plate is pressed tightly against the locking plane at the bottom of the first shaft, preventing the first shaft from rotating. After the bracket is folded up, the self-locking plane on the connecting ring fits against the locking plane, achieving the self-locking function of the bracket and preventing it from unfolding on its own due to inertia after folding, thus improving the user experience.
