Description

Technical Field

[0001] The utility model belongs to the technical field of louver awnings and relates to a column connection structure of a louver awning. Background Art

[0002] The louver awning is a common tool in the existing technology and is used for sun protection and rain protection. It generally includes a horizontally arranged frame and a number of columns arranged at intervals along the circumference of the frame. Specifically, the frame is generally square or rectangular, and is hinged with a number of louvers connected together by a connecting rod mechanism. The number of columns is generally set to four, and they are set at the circumferential corners of the frame. The frame is supported by four columns, and the louver blades are flipped open and closed by a motor in combination with a connecting rod mechanism or a hand-cranked wheel in combination with a connecting rod mechanism.

[0003] Regarding the connection between each column and the frame, in order to ensure later repair and maintenance, the columns and frames are currently often assembled in a detachable connection method. Specifically, there are two types. First, corresponding threaded holes are opened on the upper end of the column and the frame, and the two are locked by screwing with screws through the threaded holes. Second, a buckle is generally provided at the upper end of the column, and a bayonet is opened on the frame. The two are detachably connected by sliding engagement, and the pre-tightening force between the buckle and the inner wall of the bayonet is used to ensure the stability of the connection between the column and the frame. Of course, the buckle can also be provided on the frame, and the bayonet is opened on the column.

[0004] Obviously, compared with screw connection, the structural stability of the connection by clip connection is worse, and when in use, it is inevitable that users will lean on or accidentally hit the column, which may cause the connection between the column and the frame to fail, and there are safety hazards in use. The current screw connection method also has certain disadvantages. Considering the cost, installation convenience and maintenance convenience, the columns currently used are generally made of lighter aluminum alloy square tubes with thinner wall thickness. Moreover, the force on the screw connection part itself has reached the limit at the beginning of installation. It should be noted that the use area of ​​the louver awning is generally outdoors, so it will be exposed to wind and sun for a long time. After long-term use, the column will continue to expand and contract due to the external temperature factor, which will inevitably cause the upper screw connection of the column to deform, and there is even a risk of breakage, which poses a safety hazard in use. Summary of the Invention

[0005] The purpose of the present invention is to solve the above problems in the existing technology and propose a column connection structure for a louver awning. The technical problem to be solved by the present invention is: how to improve the connection firmness between the column and the frame.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a column connection structure of a louver awning, the louver awning includes a horizontally arranged frame, characterized in that the upper end of the column side wall has a mounting portion, the connection structure includes screws and a plate-shaped reinforcement, the reinforcement is fixed to the inner side wall of the mounting portion, the corners of the frame are abutted against the reinforcement, there are multiple screws, which pass through the mounting portion and the reinforcement in sequence and are screwed and locked with the frame.

[0007] The present invention relates to a method for fastening the support frame to a frame structure, wherein the support frame is fixed to the support frame by screws, and the support frame is fixed to the support frame by screws. The present invention relates to a method for fastening the support frame to a frame structure, wherein the support frame is fixed to the support frame by screws, and ...

[0008] In the aforementioned louvered awning column connection structure, both the mounting portion and the reinforcement are L-shaped, and the side of the reinforcement facing away from the frame is welded to the inner wall of the mounting portion. By providing both the mounting portion and reinforcement as L-shaped plates, the contact area between the reinforcement and the inner wall of the mounting portion is ensured, ensuring weld security. Furthermore, the sidewall of the reinforcement facing the frame corner better conforms to the frame's outer contour, ensuring connection stability.

[0009] In the aforementioned louvered awning column connection structure, the reinforcement member has a plurality of first reinforcing ribs vertically disposed on one side of the reinforcement member facing the inner wall of the mounting portion. These first reinforcing ribs are spaced apart along the width of the reinforcement member, and the reinforcement member is welded to the inner wall of the mounting portion via these first reinforcing ribs. The provision of these first reinforcing ribs effectively enhances the structural strength of the reinforcement member, preventing deformation of the reinforcement member under stress during use. Furthermore, each first reinforcing rib abuts and is welded to the inner wall of the mounting portion, ensuring the reinforcement member's installation stability.

[0010] In the aforementioned louvered awning column connection structure, the column has three vertical positioning ridges along its inner edge, each extending to the two ends of the column. The upper end of one positioning ridge is located in the middle of the inner wall of the mounting portion, while the upper ends of the other two positioning ridges are located at the edges of the inner wall of the mounting portion. The side of the reinforcement facing away from the frame has three vertically extending elongated connecting ribs, which abut against each of the three positioning ridges. The three positioning ridges and the three connecting ribs cooperate to quickly align the reinforcement before welding, ensuring more convenient assembly of the reinforcement. The three positioning ridges also serve to enhance the overall structural strength of the column.

[0011] In the aforementioned louvered awning column connection structure, the reinforcement member has a plurality of vertically extending abutment ribs on the side facing the frame. These abutment ribs are positioned one-to-one with the first reinforcement ribs. The abutment ribs cooperate with the first reinforcement ribs to further enhance the structural strength of the reinforcement member and provide more stable support at the circumferential corners of the frame.

[0012] In the aforementioned louvered awning column connection structure, the reinforcement member has a plurality of second vertically arranged ribs on the side facing away from the frame. These second ribs are spaced apart across the width of the reinforcement member, and their height is less than that of the first ribs. The presence of these second ribs, combined with the coordination of the first ribs, the abutting ribs, and the second ribs, further enhances the structural strength of the reinforcement member.

[0013] Compared with the existing technology, the column connection structure of the louver awning has the following advantages:

[0014] An L-shaped plate-like reinforcement is fixed to the mounting portion of the column by welding. On the basis of improving the structural strength of the top of the column (i.e. the mounting portion), the reinforcement is abutted against the corners of the frame. Screws are used to pass through the mounting portion, the reinforcement and the frame in sequence, thereby ensuring the stability of the connection between the column and the frame.
