DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] See also Figures 1 to 3 , is an anti-pinching corner connector provided in this embodiment, including an inner connecting piece 001 located on the inner side, an outer connecting piece 002 located on the outer side, and a top connecting piece 003 located above and used to connect the inner connecting piece 001 and the outer connecting piece 002; the inner connecting piece 001 is L-shaped, and rounded corners are set at the corners. It includes a first connecting piece 011 and a second connecting piece 012 that are perpendicular to each other, and outward-protruding rounded corners are set below the first connecting piece 011 and the second connecting piece 012. The rounded corner protrusions are provided in conjunction with the L-shaped structure of the inner connecting piece 001, which can effectively avoid the problem of pinching hands.

[0030] A first connecting end 010 and a second connecting end 020 are formed between the inner connecting piece 001 and the outer connecting piece 002. The extension lines of the centers of the first connecting end 010 and the second connecting end 020 are perpendicular to each other. The outer connecting piece 002 is L-shaped with rounded corners. It includes a third connecting piece 021 and a fourth connecting piece 022 that are perpendicular to each other. An inwardly concave arcuate groove 211 is provided below the third and fourth connecting pieces 021 and 022.

[0031] The top connecting piece 003 is arched upward near the first connecting end 010 and the second connecting end 020 to provide space for folding. Therefore, the upper end surface of the top connecting piece 003 is curved, and its connection with the inner connecting piece 001 and the outer connecting piece 002 is rounded to prevent scratching hands. Limiting steps 004 are provided below the top connecting piece 003 and at the first connecting end 010 and the second connecting end 020 to enhance the overall strength of the corner connector and to provide a limiting function. Two limiting steps 004 can be provided side by side: two side-by-side limiting steps 004 are provided below the top connecting piece 003 and at the opening of the first connecting end 010, and two side-by-side limiting steps 004 are provided below the top connecting piece 003 and at the opening of the second connecting end 020.

[0032] A reinforcement sheet 005 is also provided inside the inner connecting sheet 001, with a gap between the reinforcement sheet 005 and the inner connecting sheet 001. Specifically, the top of the reinforcement sheet 005 is fixedly connected to the inner side of the inner connecting sheet 001. The shape of the bottom of the reinforcement sheet 005 is consistent with that of the bottom of the inner connecting sheet 001, which improves the overall appearance and prevents problems such as scratching and pinching of hands. The reinforcement sheet 005 not only provides reinforcement, but also provides a certain degree of elasticity when the screws are tightened due to the gap, which prevents the screws from loosening.

[0033] A cylindrical tube 006 with a third connection end 030 is provided between the outer connecting piece 002 and the inner connecting piece 001. The outer side of the cylindrical tube 006 is located on the inner side wall of the outer connecting piece 002 and at the corner. A reinforcing rib 007 is provided between the inner connecting piece 001 and the cylindrical tube 006.

[0034] The inner connecting piece 001, the outer connecting piece 002, the top connecting piece 003, the reinforcing piece 005, the cylindrical tube 006 and the limiting step 004 in this embodiment are an integrated structure and are plastic parts, which are made of plastic material by injection molding.

[0035] See also Figures 1 to 4The present invention also provides a folding bed stand that utilizes an anti-pinch corner connector. The folding bed stand also includes a first connecting rod 081 and a second connecting rod 082 rotatably connected to the corner connector, and a third connecting rod 083 disposed on the corner connector. The first connecting rod 081 and the second connecting rod 082 are located at a first connecting end 010 and a second connecting end 020, respectively, and the third connecting rod 083 is embedded within the third connecting end 030. Due to the avoidance space set in the top connecting piece 003, there is enough space for the first connecting rod 081 and the second connecting rod 082 to rotate, avoiding the influence of small space on rotation. At the same time, for the purpose of connection, through holes are set on the first connecting rod 081 and the second connecting rod 082 for connecting with the corner connecting parts. Due to the setting of the avoidance space, the position of the through hole does not need to be too close to the end face of the first connecting rod 081 or the second connecting rod 082, thereby improving the firmness of the connection. At the same time, since the limiting steps 004 are set in the first connecting end 010 and the second connecting end 020, when the folding bed bracket is unfolded, the first connecting rod 081 and the second connecting rod 082 can be limited.

[0036] The folding bed bracket is provided with four corner connectors, and are located at the four corners of the rectangle. Any corner connector is provided with a first connecting rod 081, a second connecting rod 082 and a third connecting rod 083. Folding devices are provided between every two first connecting rods 081 and every two second connecting rods 082. By setting the folding device, the folding effect of the bracket is achieved. The folding device can directly adopt the existing folding structure, and the specific fixed installation method can also adopt the existing technology.

[0037] In summary, the corner connector of the present invention forms an L-shaped structure by arranging raised rounded corners on the first connecting piece and the second connecting piece of the inner connecting piece, which can avoid pinching hands; at the same time, the reinforcement piece provided can strengthen the overall structure and avoid problems such as loose screws.
