[0023] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] According to an embodiment of the present utility model, a square tube quick connection fastener is provided.

[0025] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-5 As shown, a square tube quick connection fastener according to an embodiment of the present invention includes a fastener 1 and a square tube 2. The square tube 2 is provided with an array, and the array square tube 2 is connected by the fastener 1. The fastener 1 is provided with a fixing block 3, a positioning block 4 and a limit block 5. The fixing block 3 is connected to the top of the limit block 5, the positioning block 4 is bent at the side of the limit block 5, and is arranged in the opposite direction to the fixing block 3 to form a locking cavity. The fixing block 3 is connected to the upper end of one group of square tubes 2, and the other group of square tubes 2 is installed in the locking cavity. The fixing block 3, the positioning block 3 and the limit block 5 are provided with an array mounting hole 6.

[0026] In one embodiment, the fastener 1 is an integrally formed component.

[0027] In one embodiment, the square tube 2 is sized to match the locking cavity. The size of the square tube 2 to be connected is appropriately determined. This facilitates installation and fit of the square tube 2. Fastening the square tube 2 to the square tube 2 with fasteners such as bolts enhances connection reliability. The square tube 2 can be made of aluminum alloy, stainless steel, or ordinary carbon steel, depending on the specific application scenario. The square tube 2 has a square or rectangular shape.

[0028] In one embodiment, the fixing block 3 is connected to the limiting block 5 by bending, the fixing block 3 is perpendicular to the upper end of the limiting block 5, and the edges of the fixing block 3 and the limiting block 5 are provided with arc angles.

[0029] In one embodiment, the positioning blocks 4 are provided in three groups, and the three groups of positioning blocks 4 are bent and welded together by laser welding. Laser welding can ensure welding quality, reduce welding deformation, and make the connection between the positioning blocks 4 firm and smooth in appearance.

[0030] In one embodiment, a through hole 51 is formed in the center of the stop block 5. The stop block 5 serves as the basic supporting part of the entire fastener 1 and has a rectangular shape.

[0031] Working principle: When connecting the square tubes 2, first place one group of square tubes 2 on the back of the limit block 5 so that it fits with the fixed block 3. It can be preliminarily fixed by inserting bolts into the mounting holes 6 of the fixed block 3. Then, align the other group of square tubes 2 with the locking cavity formed by the positioning block 4 on the side of the limit block 5 and insert it. Due to the angle of the positioning block 4 and the connection relationship with the limit block 5, the square tubes 2 can smoothly enter the locking cavity along the predetermined direction, and after being inserted into place, they are restricted by the inner wall of the locking cavity and will not fall out easily. The fastener 1 is an integrally formed component that firmly connects the two groups of square tubes 2 together. The connection operation is performed using bolts and other connectors through the mounting holes 6 opened on the positioning block 4. When disassembly is required, just remove the bolts and then pull out the square tube 2 from the corresponding position. The operation is simple and convenient, and the fastener 1 is reusable, which reduces the cost of use.

[0032] In the present invention, unless otherwise clearly stipulated and limited, the terms "install", "set", "connect", "fix", "screw" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
