Description

RELATED APPLICATIONS

The present patent document claims the benefit of priority to Patent Application No. 202422359239.X, filed September 26, 2024, and entitled “telescopic photo frame,” the entire contents of each of which are incorporated herein by reference.

BACKGROUND

1. Technical Field

The present disclosure relates to the technical field of photo frames, and in particular to a telescopic photo frame.

2. Background Information

General-purpose photo frames in the prior art are made based on common photo sizes, and the photo frames need to be customized for special sizes of photos or paintings.

To enhance the adaptability of photo frames to photos or paintings of different sizes, some manufacturers have developed telescopic and adjustable photo frames. Specifically, a length of frame borders of a photo frame is adjusted by retraction to adapt to photos or paintings of different sizes, with structural details as follows: Each of the frame borders is provided with a fixed frame and a telescopic frame, the fixed frame is provided with a plurality of adjustment holes, and the telescopic frame is provided with opening holes corresponding to the adjustment holes. Size adjustment is achieved by aligning the adjustment holes with the opening holes, and then fixing is performed by means of screws. However, this structure cannot achieve stepless adjustment, and still has deficiencies such as inadaptability to some sizes and difficulty of aligning the adjustment holes with the opening holes.

Additionally, another structure is as follows: The fixed frame and the telescopic frame are provided with matching slots, nuts are installed in the slots, and the slots of the fixed frame and the telescopic frame are clamped or pressed tightly through the cooperation of screws, gaskets, and nuts, which achieves the stepless adjustment. However, the slots of this structure are easily deformed, which results in jamming during telescopic adjustment. Additionally, indentations caused by gaskets are formed on the frame borders, thereby affecting the aesthetics.

Therefore, there is an urgent need for a telescopic photo frame that can solve one or more problems above.
