Specifically, as shown in fig. 1 to 6, the lifting foot stool of the present invention comprises a first supporting component 1, a second supporting component 2, a third supporting component 3, an adjusting component 4, a first hinge shaft 5, a second hinge shaft 6, a third hinge shaft 7, and a fourth hinge shaft 8; the first supporting component 1 and the second supporting component 2 are hinged through two first hinge shafts 5; the first end of third supporting component 3 and the top of first supporting component 1 are through articulated setting of two second articulated shafts 6, the top of second supporting component 2 sets up two third articulated shafts 7, the position that is close to third supporting component 3 second end is provided with two sliding trays 10, third articulated shaft 7 can slide in sliding tray 10, the one end of adjusting part 4 and third supporting component 3 are through articulated setting of two fourth articulated shafts 8, adjusting part 4 is provided with two tooth type grooves, third articulated shaft 7 passes sliding tray 10 and tooth type groove 9 in proper order. The tooth-shaped groove 9 is hinged with the third supporting component 3 through the fourth hinge shaft 8, when the tooth groove 91 of the tooth-shaped groove 9 is matched with the third hinge shaft 7, the tooth-shaped groove 9 can realize one-way or two-way locking of the third supporting component 3, the principle is that the tooth groove 91 of the tooth-shaped groove 9 is provided with a self-locking characteristic surface 93 which forms self-locking torque with the sliding groove 10, the self-locking characteristic surface 93 refers to a tooth groove 91 shape, the self-locking characteristic surface 93 is a shape, the self-locking characteristic surface 93 can be designed into one surface or two surfaces, and acting force and component force generated when the third hinge shaft 7 slides in the sliding groove and is abutted against the side wall of the tooth groove 91 can not overcome gravity and friction force of the adjusting. When the tooth grooves 91 of the tooth-shaped grooves 9 are separated from the third hinge shaft 7, the third hinge shaft 7 can freely slide in the sliding grooves 10, and when the sliding motive power generated by the third hinge shaft 7 is manually lifted up and down by the adjusting assembly 4, the first supporting assembly 1 and the second supporting assembly 2 swing due to gravity. The first supporting component 1, the second supporting component 2, the third supporting component and the third hinge shaft 7 form a slider-crank mechanism, when different tooth spaces 91 of the third supporting component 3 lock the third hinge shaft 7, the position (height) of the first hinge shaft 5 changes relative to the position of a central connecting line between the second hinge shaft 6 and the third hinge shaft 7, so that the third supporting component 3 changes in height relative to the first hinge shaft 5, and the height of the foot rest is increased or decreased.

Preferably, as shown in fig. 5 and 6, the tooth-shaped grooves 9 include a plurality of tooth grooves 91 and a rectangular groove 92, and the tooth grooves 91 communicate with the rectangular groove 92.

Preferably, as shown in fig. 1 and 2, the first support member 1 and the second support member 2 are frame structures. The first support component 1 and the second support component 2 can be assembled by square pipes, angle steel or other sectional materials. The existing section bar has good strength due to low cost, and can meet the strength requirement of the lifting foot rest.

Preferably, as shown in fig. 1, the first support member 1 and the second support member 2 are identical in structure.

Preferably, as shown in fig. 1, the width of the sliding groove 10 is larger than the diameter of the third hinge shaft 7.

Preferably, as shown in fig. 1, at least one reinforcing cross bar is arranged between two vertical bars of the first support assembly 1 and the second support assembly 2. The utility model discloses in set up two between two montants of first supporting component 1 and second supporting component 2 and strengthen the horizontal pole. The reinforced cross rod enables the lifting foot rest to have reinforced torsion resistance, and the stability and the reliability of the lifting foot rest are further improved.

On the other hand, the utility model also provides a lifting table, lifting table includes foretell lift foot rest and desktop, and the table is fixed on third supporting component 3.

The utility model discloses a concrete motion process: the power of the foot-lowering frame lifting is preferably manual lifting, manual pressing, the self weight of the assembly, lifting or pressing of the third supporting assembly 3, and meanwhile, the adjusting assembly 4 is manually stirred upwards to enable the tooth grooves 91 to be separated from the third hinge shaft 7 in an abutting mode, so that the tooth grooves 91 are not intersected with the sliding grooves 10, and the third hinge shaft 7 can freely slide in the sliding grooves 10. When the lifting force transmitted to the third supporting component 3 is greater than the self weight and the friction force of the whole component, the third supporting component 3 rises, the third hinge shaft 7 slides leftwards, when the lifting force transmitted to the third supporting component 3 is less than the self weight and the friction force of the whole component, the third supporting component 3 can descend, the third hinge shaft 7 slides rightwards, the first supporting component 1 and the second supporting component 2 swing downwards or upwards along with the rising or descending of the third supporting component 3, and the third supporting component 3 can slide rightwards or leftwards in the sliding groove 10 of the third supporting component 3 along with the upward or downward swinging of the first supporting component 1 and the second supporting component 2. When the adjusting assembly 4 is pulled downwards, an included angle is formed between the rectangular groove 92 of the adjusting assembly 4 and the sliding groove 10 after the rectangular groove 92 and the third hinge shaft 7 are abutted, the size of the included angle is changed by the position change of the third hinge shaft 7 in the sliding groove 10 in the manner of being abutted against the side wall of the tooth groove 91, when the positions of all the sections of the tooth grooves 91 of the third supporting assembly 3 are correspondingly abutted against the positions of all the sections of the sliding groove 10 of the third hinge shaft 7, the third hinge shaft 7 is abutted against a certain self-locking feature surface 93 of the side wall of the tooth groove 91 of the adjusting assembly 4, the self-locking feature surface 93 can prevent the third hinge shaft 7 from continuously sliding in the sliding groove 10, so that the height of the third supporting assembly 3 is locked, and the multi-section height change of the third supporting assembly 3 can be realized when the multi-section tooth grooves 91 of the adjusting assembly 4 and the third hinge shaft 7 are correspondingly abutted against the sliding groove 10, so that.

So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
