Technical Field

[0001] The present invention relates to the technical field of outdoor awnings, in particular to a non-welded awning frame fixing structure for a louver awning.Background

[0002] 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.

[0003] 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.

Detailed Description

[0018] In order to make the technical means, creative features, objectives, and effects of the present utility model easy to understand, the present invention is further elaborated in combination with specific drawings.

[0019] It should be noted that all directional indications (such as up, down, left, right, front, rear...) in the embodiments of the present invention are only used to explain the relative positional relationship, movement conditions, and the like between components in a specific attitude (as shown in the accompanying drawings), and if the specific attitude changes, the directional indication also changes accordingly. In addition, the descriptions relating to 'first', 'second' and the like in the present utility model are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implying the numbers of technical features indicated. Thus, the features defined with the 'first' and 'second' may explicitly or implicitly include at least one of the features.

[0020] As shown in FIG. 1 to FIG. 10, the embodiment discloses a non-welded awning frame fixing structure for a louver awning, including a ring beam frame and leg tubes 2, where the ring beam frame includes at least three ring beams 1. In other preferred embodiments, four ring beams 1 may be available so as to form a square ring beam frame; five ring beams 1 may also be available so as to form a ring beam frame shaped like a Chinese character 'RI', and six ring beams 1 may also be available so as to form a ring beam frame shaped like a Chinese character 'MU'; and according to the requirements of the louver awning, corresponding extended settings may be carried out, and it is not limited to the corresponding shape specifications in the above embodiments. The non-welded awning frame fixing structure may also be a polygonal frame structure.

[0021] Ring beam splicing portions are provided at upper ends of the leg tubes 2, and the ring beam splicing portions are used to cooperate with the ring beams 1 for installation; and each of the ring beam splicing portions includes a splicing side wall 21, a clamp slot 22 formed on the splicing side wall 21, and at least one lateral notch 25, where end positions of the ring beams 1 are usually matched with the lateral notches 25 for installation. The specific structure is that each of the ring beams 1 includes a ring beam body 11 and an insert piece 16 fixed on a side wall of the ring beam body 11, and the insert piece 16 and the clamp slot 25 are used to hang the ring beam body 11 on the lateral notch 25 by means of mortise and tenon fit. The number of the lateral notches 25 is preferably two, which are arranged adjacent to each other. The two lateral notches 25 are usually symmetrically disposed along a diagonal line. The splicing side wall 21 corresponding to the individual lateral notch 25 is correspondingly provided with the clamp slot 22, an adjusting groove 23, and a fastening groove 24 in a matching manner. A position-limit clamp wall 26 is preferably disposed between the two adjacent lateral notches 25, and the position-limit clamp wall 26 is used to limit the installation position of the ring beam 1 to avoid the displacement of the ring beams 1 after being hanged. In addition, the hanging structure is used to make the bottom surface of ring beam 1 and the bottom edge of the lateral notch 25 contact with each other. The bottom edge of lateral notch 25 can provide a large bearing capacity for the ring beam 1, thus reducing the longitudinal stress between other components, and making the installation of all components more stable.

[0022] In one of the exemplary embodiments, the interior of each of the ring beam bodies 11 has a cavity structure, and also comprises an inner lining plate 4; and the inner lining plate 4 is embedded in the inner cavity of the ring beam body 11 and is provided with first alignment holes 41 and second alignment holes 42. In one of the exemplary embodiments, the second alignment holes 42 are located on both sides of the first alignment holes 41, which is a double-hole arrangement to facilitate the assembly of the inner lining plate 4, so that there is no need to carry out position alignment, and both the positive and negative sides can be used for installation in position. In other embodiments, it can be a single-hole arrangement; each of the inner lining plates 4 includes a transverse lining plate 45 and a vertical lining plate 44; the first alignment holes 41 and the second alignment holes 42 are both formed in the vertical lining plate 44, and a third alignment hole 43 is formed in the transverse lining plate 45; and a third fixing hole 14 is formed in the upper surface of the ring beam body 11, and the third alignment hole 43 and the third fixing hole 14 are correspondingly matched. In one of the embodiments, the cross section of the inner lining plate 4 has a L-shaped structure, and the transverse lining plate 45 and the vertical lining plate 44 are matched with each other at 90°. In another embodiment, the cross section of the inner lining plate 4 has a "[" structure, and the transverse lining plates 45 are disposed up and down. The structure is convenient for aligning with the inner cavity of the ring beam body 11, has better strength, and is convenient to assemble.

[0023] The structural arrangement of the built-in inner lining plate 4 is optimized, and the fixed installation of the ring beam body 11 and the insert piece 16 is more stable; and furthermore, the fixing strength of the part is strengthened, and the bearing capacity between the parts is improved.

[0024] In one of the exemplary embodiments, the non-welded awning frame fixing structure for a louver awning further includes sealing plates 3, each of the sealing plates 3 is provided with first sealing holes 31, fasteners passing through the first sealing holes 31, the third fixing holes 14, and the third alignment holes 43 allow the same to be fixed and matched to complete the integral fixation among the sealing plates 3, the ring beams 1, and the inner lining plates 4.
