Description

Technical Field

The present utility model relates to the technical field of outdoor awnings, in particular to a non-welded awning frame fixing structure for a louver awning.

Background

Outdoor awnings have various structural styles, and can be either used as folding awnings for folding storage, or used as fixed awnings directly placed in outdoor courtyards or parks. As one of the fixed awnings, the louver awning has a top face adopting a louver structure, and a linkage mechanism enables a louver to be turned over, so that a function of shading or opening is realized. The louver awning is popular with consumers because of its advantage of light adjustment.
A awning frame structure in existing louver awnings on the market is usually formed by installing a ring beam and leg tubes which are fixed with each other. In the existing design, an end of a component in the ring beam or the leg tube is usually welded with a fixed connecting component in a matching manner, and the connecting component is used to complete the abutted fit with the ring beam or the leg tube. This type of structure has the following disadvantages that: 1. the welded components are prone to failure during long-term use, especially the welding positions of the connecting components are usually main stress positions, resulting in a high requirement for welding; 2. in order to improve aesthetics of appearance, the welding positions usually need to be polished, so that welding fixation is higher in cost for product manufacturing; and 3. the welding fixation is a non-detachable fixed structure, resulting in the relatively large overall awning frame, which easily causes the specifications of individual components to exceed a limit, and thus increases the product logistics cost and packaging cost.
