As shown in fig. 1-3, the locking fixing device of the outdoor folding table according to the present embodiment includes a locking fixture block 4, where the locking fixture block 4 includes an upper fixture plate 41, the upper fixture plate 41 is hinged on a side surface of the table frame 1, a front end of the upper fixture plate 41 is an upper fixture plate arc head 411, two sides of a rear end of the upper fixture plate 4 are arc-shaped, a locking sloping plate 42 is provided at a bottom end of the upper fixture plate 41, and a C-shaped clamping groove 43 is provided on an inner side surface of the locking sloping plate 42;

the C-shaped clamping groove 43 is matched with an arc clamping head 313 arranged at the upper part of the outer side surface of the supporting plate leg 31 of the table supporting frame 3; the supporting plate leg 31 is hinged on the table frame 1; the top of the supporting plate leg 31 is arc-shaped, a clamping block arc groove 312 is formed between the top of the supporting plate leg 31 and the arc clamping head 313, and the clamping block arc groove 312 is matched with the upper clamping plate arc head 41.

Further, the top ends of the support plate legs 31 are arc-shaped to form support plate leg arc-shaped heads 311; the bottom ends of the support plate legs 31 are square in shape.

Further, the end surface of the upper clamping plate 41 between the C-shaped clamping groove 43 and the clamping plate arc-shaped head 41 is an arc-shaped surface.

Further, the bottom end of the locking sloping plate 42 is arc-shaped.

In the design, a plurality of rectangular frame plates 2 are arranged on the top surface of the table frame 1 to form a table top. The two sides of the table frame 1 are respectively hinged with a table supporting frame 3, so that the table frame can be folded. A locking and fixing device is arranged at the joint of the table support frame 3 and the table frame 1, so that the table support frame 3 and the table frame 1 can form a lock catch conveniently.

In the design, the upper clamping plate 41 of the locking clamping block 4 is provided with a locking clamping block shaft hole 44, the locking clamping block shaft hole 44 is provided with a first rotating shaft, and the first rotating shaft is connected with the table frame 1 to form a hinge.

In the design, two ends of the table frame 1 are respectively hinged with a table supporting frame 3. Two support plate legs 31 of the table support frame 3 are respectively connected with two ends of one end of the table frame 1, and a horizontal plate can be arranged between the two support plate legs 31, so that the table support frame 3 in an H shape is formed.
