Referring to fig. 1 to 6, the simple folding table of the present invention includes a table plate 10, supporting legs 20 and a bracket 30 connected between the table plate and the supporting legs, wherein the table plate 10 and the supporting legs 20 can be independently folded relative to the bracket 30. The support 30 is i-shaped and includes a vertically disposed support rod 31, an upper cross rod 32 connected to the upper end of the support rod 31, and a lower cross rod 33 connected to the lower end of the support rod. The upper cross bar 32 is located at the rear of the bottom surface of the table top 10, and the table top 10 can be turned around the upper cross bar 32. Two ends of the upper cross bar 32 are symmetrically provided with two locking plates 34, a plurality of locking holes 35 are arranged on the locking plates 34 at intervals along an arc track, and the table further comprises a locking bar 40 which is movably arranged at the bottom of the table 10 and is used for being inserted into the locking holes 35. The desk plate 10 can be horizontally placed, or can be turned downwards to be vertically folded or can be obliquely downwards placed, the locking rod 40 is pulled out, so that the desk plate 10 can be turned over, the angle of the desk plate 10 can be adjusted, and after the desk plate is adjusted to a desired position, the locking rod 40 is inserted into the locking hole 35 again to lock the desk plate 10. The support foot 20 is rotatably connected to the lower cross bar 33 and can be rotatably switched between at least a horizontal position (in a standing state) and a vertical position (in a folded state), and of course, the support foot 20 may be inclined. And a locking mechanism capable of locking the support foot 20 at least in the horizontal and vertical positions. There is no diagonal bracing between the table board 10 and the supporting legs 20, so that the table board has a larger moving space and a simpler structure.

The supporting legs 20 are two and symmetrically connected to both ends of the lower cross bar 33. The bottom cross bar 33 is a hollow bar, the ends of the supporting feet 20 are inserted into the bottom cross bar 33, and each supporting foot 20 can independently rotate relative to the bottom cross bar 33. The supporting legs 20 are L-shaped, and the two supporting legs 20 and the lower cross bar 33 form a U-shaped frame. So that the support feet 20 do not interfere with the user's foot placement. And two blocking head sleeves 50, wherein the blocking head sleeves 50 are sleeved on the lower cross bar 33 and cover the connecting positions of the supporting legs 20 and the lower cross bar 33.

The locking mechanism comprises a pin 61 arranged on the supporting foot 20 and a plurality of clamping grooves 62 arranged at intervals along the periphery of the opening of the lower cross bar 33, and the pin 61 is transversely inserted into the clamping grooves 62 to lock the supporting foot 20. The number and location of the slots 62 can be designed based on the angle of inclination that the support foot 20 is intended to lock. The locking mechanism further includes a tension spring 63 disposed in the lower cross bar 33, wherein the tension spring 63 inwardly tensions the two support legs 20, so that the pin 61 is inserted into the slot 62. When the supporting foot 20 needs to be folded, the supporting foot 20 is pulled to the direction that the pin 62 exits the slot 62 against the elastic force of the tension spring 63. The unlocking operation is simple.

The table board 10 is provided with a receiving groove 11 corresponding to the locking plate 34, and the top surface of the receiving groove 11 protrudes upward from the top surface of the table board 10.

When unlocking is desired, locking bar 40 is moved laterally inwardly against the force of spring 14 by pulling handle 42 laterally inwardly.

The table plate 10 comprises a lower bottom plate 10-1 and an upper surface plate 10-2, wherein the lower bottom plate 10-1 is an injection molding plate and has better strength, so that the mounting seat 12 and the limiting block 13 can be better arranged. Two pivoting bases 15 are symmetrically arranged on the left and right sides of the bottom surface of the desk plate 10, two ends of the upper cross bar 32 are respectively pivoted on the two pivoting bases 15, and the pivoting bases 15 are also arranged on the lower base plate 10-1. The upper panel 10-2 is a plastic-absorbing panel, and has the advantages of thin thickness, light weight and good flatness. The front edge of the upper panel 10-2 is provided with an upwardly convex rib 16.

The supporting rod 31 is of a telescopic structure so as to conveniently adjust the height of the table board 10.

The rear side of the locking plate 34 is provided with a vertically arranged connecting plate 36, and the connecting plate 36 is provided with a hanging hole 37. Preferably, the connecting plate 34 is located further back than the supporting rod 31 or is flush with the back surface of the supporting rod 31, so that a gap between the folding table and the wall surface after the folding table is hung on the wall surface can be eliminated.

Referring to fig. 7 and 8, since the two locking plates 34 are provided with hanging holes 37 at the rear sides thereof, the folding table can be hung on a screw of a wall surface by using the hanging holes 37, as shown in fig. 7, the supporting legs 20 are retracted, the table plate 10 is unfolded, and the folding table can be used for hanging on a wall. As shown in fig. 8, when not in use, the desk board 10 and the supporting legs 20 can be folded and then hung on the wall surface for storage.
