[0034] Referring to Figures 1 to 8 , the folding side table comprises a table board 1, a table leg 2 and a stand 3; the table board 1 is positioned on the stand 3, and a hand control angle adjuster 10 is arranged between the bottom of the table board 1 and the upper end of the stand 3, so as to support the table board 1 in an open state to a state of being folded on the side of the stand 3; the table leg 2 is rotatably positioned at the lower end of the stand 3 through a rotating shaft, and a pedal unlocking mechanism 20 is arranged between the table leg 2 and the stand 3, so as to keep the table leg in an open supporting state and a folded position on the side of the stand.

[0035] As Figure 6 and Figure 7, hand control angle adjuster 10 and foot pedal unlocking mechanism 20, both including angle disc 4 and lock pin 5, and spring 6 and flap 7, lock pin 5 always maintains the tendency to lock angle disc 4 under the action of spring 6; flap 7 is positioned on connecting bracket 11 and connecting bracket seat 21 of table leg corresponding to the shaft, flap 7 has swing part 71 and driving part 72, swing part 71 is linked with lock pin 5, and can drive lock pin to release the locked state of lock pin to the notch 41 distributed on the arc edge of angle disc; spring cylinder is formed on the connecting bracket and the connecting bracket seat, and the end of the spring arranged in the spring cylinder abuts against the lock pin or the flap, always keeping the tendency of the lock pin entering the notch 41 of the angle disc in the locked state.

[0036] The above-mentioned flap 7 is linked with the lock pin 5, and has the following two structures:

[0037] In the drawing, the flap 7 and the lock pin 5 are in a split structure, the lock pin 5 is connected with a guide cylinder 51, and is symmetrically distributed in the radial direction of the guide cylinder 51; the outer diameter of the guide cylinder 51 is smaller than the inner diameter of the spring cylinder 61, and is inverted on the end of the spring 6, forming a piston-like action to ensure the smooth action of the lock pin 5; the swing part 71 of the flap can abut against the bottom of the guide cylinder 51 or be buckled on the surface of the lock pin 5 to drive the guide cylinder 51 to compress the spring 6.

[0038] Alternatively, the flap 7 and the lock pin 5 are in a connected structure, and are directly fixed on the swing part 71 of the flap, the end of the spring 6 abuts against the flap 7 or the lock pin 5, and a guide column capable of being inserted into the end of the spring 6 is arranged on the flap 7 or the lock pin 5, forming a constraint to the end of the spring 6.

[0039] Since the hand control angle adjuster 10 and the foot pedal unlocking mechanism 20 have the same principle, the above is the common part, and the differences will be described separately below.

[0040] As Figure 4 and Figure 6 The flap 7 corresponding to the hand control angle adjuster 10 is an L-shaped flap, the horizontal end is the swing part 71, and the vertical end is the driving part 72; the vertical driving part 72 is pulled by a brake wire 721, and the brake handle 722 of the brake wire is arranged at the edge of the bottom surface of the table top 1, which is convenient for hand grasping and releasing operation; the L-shaped flap corner is formed with a flap shaft 73, which is positioned in the shaft hole 111 of the connecting bracket 11, and the swing part 71 abuts against the bottom of the guide cylinder 51. The matched angle disc 4 has dense notches in addition to the corresponding notches 41 at the two angles of folding in place and opening to the horizontal state, so as to adjust the different inclinations of the table top 1 to meet the different needs of reading, writing or lecturing, and the design is more humanized, and the hand control angle adjuster 10 can be used to adjust the table top accurately with both hands.

[0041] If the flap 7 and the lock pin 5 are in a connected structure, the swing part 71 is directly fixed with the lock pin 5.

[0042] As Figure 5 And Figure 7 , the rocker 7 corresponding to the pedal unlocking mechanism 20 is a mouth-shaped rocker, the opening 711 can be sleeved outside the spring barrel 61, the driving part 72 extends out of the angle disc 4 and can be touched by the foot, and the pedal is used to realize the operation without bending over. More specifically, the mouth-shaped rocker is in a wave shape, the front end of the opening 711 is shaped into a rocker shaft 73, the two sides are shaped into C-shaped arching swing parts 71, and the rear end is shaped into a driving part 72 for the pedal; the rocker shaft 73 is arranged in the shaft groove 211 of the connecting bracket 21, and a shaft cover 212 is additionally arranged above the shaft groove 211; the swing part 71 is buckled on the surface of the lock pin 5 by means of the C-shaped arching, and drives the unlocking action downward. The matched angle disc 4 generally only needs to be correspondingly provided with two notches 41 when the table leg 2 is folded to the position and unfolded to the position, and other parts are kept smooth and arc-shaped, so that the lock pin 5 can slide along the arc-shaped surface with little resistance until it enters the notch 41 to realize self-locking; no matter the hand-controlled angle adjuster 10 or the pedal unlocking mechanism 20, the external force only completes the unlocking action, and the self-locking is completed by the spring 6 and maintained in the locked state.

[0043] If the rocker 7 and the lock pin 5 are in a connected structure, that is, the swing part 71 is fixed to the lock pin 5 by means of the C-shaped arching, and the unlocking action can be driven downward.

[0044] Referring to Figure 2 And Figure 8 , the stand 3 is in a telescopic structure, including an inner column 31, an outer column 32 and a controllable gas spring 33 for driving the telescopic movement, and the control handle 331 of the controllable gas spring 33 is arranged at the edge of the bottom surface of the table top 1, so that the hand can be conveniently held to operate.

[0045] The inner column 31 and the outer column 32 are shaped with two or more than two pairs of arc-shaped sliding grooves 34 in the telescopic direction, a plurality of ball bearings 35 are arranged in the arc-shaped sliding grooves 34, and the movement gap between the inner column 31 and the outer column 32 is maintained by the ball bearings 35; the ball bearings 35 are provided with a support 36, the support 36 is shaped with a row of round holes 361 from a steel sheet, and the distance between the ball bearings 35 is maintained by the round holes 361 on the support.

[0046] Further, the supports 36 on the adjacent two or three arc-shaped sliding grooves 34 of the inner column 31 are in a connected structure, as Figure 8 , shaped from a steel sheet or plastic, the supports 36 at the edges are in an inverted folding structure, the ball bearings 35 on the inverted folding supports 36 at the two edges form a tight positioning on the inner column 31; the adjacent round holes 361 of the support 36 are provided with a anti-falling baffle 362, the anti-falling baffles 362 are uniformly arranged on the outer side of the inverted folding supports 36, that is, inwardly clamped on the inner column 31, so as to facilitate assembly and maintain stability during use.
