Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a desktop lifting device, including: the base 1, the lifting structure 2 and the desktop 3 are arranged in sequence;
the lifting structure 2 comprises a first plate 201, a second plate 202 and a third plate 203 which are sequentially arranged, the first plate 201 and the second plate 202 are oppositely arranged, a first end of the first plate 201 and a first end of the second plate 202 are both pivotally connected with the base 1, a second end of the first plate 201 is pivotally connected with the table top 3 through a first rotating shaft 4, a second end of the second plate 202 and a first end of the third plate 203 are both pivotally connected with the table top 3 through a second rotating shaft 5, and a second end of the third plate 203 is slidably arranged in a guide rail on the base 1, so that the lifting structure 2 and the table top 3 have a first state and a second state;
in the first state, the second end of the third plate 203 moves towards the second plate 202, so that the included angle between the second plate 202 and the third plate 203 is a first included angle, and the tabletop moves away from the base 1; in the second state, the second end of the third plate 203 moves away from the second plate 202, so that the included angle between the second plate 202 and the third plate 203 is a second included angle, the tabletop 3 moves close to the base 1, and the first included angle is smaller than the second included angle.
Wherein, the theory of operation of the embodiment of the present invention can be seen in the following expression:
in the first state, the second end of the third plate 203 moves towards the second plate 202, and at the same time, the first rotating shaft 4 and the second rotating shaft 5 rotate, so that the first plate 201, the second plate 202 and the third plate 203 can be driven to rotate, the table top 3 moves away from the base 1, when the second end of the third plate 203 moves to the first position, referring to fig. 2-5, an included angle between the second plate 202 and the third plate 203 can be a first included angle, and at this time, the height corresponding to the table top 3 is a first height; in the second state, the third end of the third plate 203 moves away from the second plate 202, and at the same time, the first rotating shaft 4 and the second rotating shaft 5 rotate, so as to drive the first plate 201, the second plate 202 and the third plate 203 to rotate, the table top 3 moves near the base 1, when the second end of the third plate 203 moves to the second position, referring to fig. 6-9, the included angle between the second plate 202 and the third plate 203 can be a second included angle, and the height corresponding to the table top 3 at this time is a second height.
It should be noted that the direction of the arrows in fig. 2 and 6 may be used to indicate the moving direction of the table top 3.
It should be noted that the first included angle is smaller than the second included angle, and the first height is greater than the second height. For example: the value of the first included angle may be 45 degrees, and the value of the second included angle may be 180 degrees or 175 degrees. The second height minus the height of the base 1 may be the thickness of the table top 3, i.e., the table top 3 abuts the base 1 when the table top 3 is at the second height, as shown in figures 6-9. The height of the base 1 can be the height of the highest point of the base 1, and the height of the table top 3 is the height of the upper surface of the table top 3.
