Description

Parallel lifting mechanism

Technical Field

The utility model relates to an elevating system technical field particularly, relates to a parallel elevating system.

Background

In work or study, people have a demand for lifting adjustment of articles such as tables, chairs, furniture and the like, and particularly for tables which are frequently used in daily life, for example, the table top is required to be adjusted to different suitable positions and heights. Especially for children, due to the difference of individual height and arm length, and the consideration of different purposes of drawing and learning, the requirements of the learning table can be adjusted to meet the use requirements of children, the prior art solves the problems by lifting the table top, but the realization mode can only realize lifting adjustment, but can not simultaneously adjust the position and can not realize the function of parallel lifting;

and the motion part still has the transmission of adopting lead screw and complicated rhombus extension subassembly, and stability is difficult to control, and the structure is complicated moreover, makes whole desk heavy, and the installation is dismantled inconveniently, and more importantly children experience is relatively poor, can't in time adjust to suitable angle.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a parallel elevating system, its specific scheme is as follows:

a parallel lifting mechanism comprises a cross shaft bracket, mounting seats are arranged at two ends of the cross shaft bracket, an upper arm and a forearm are mounted on the mounting seats, the upper arm and the forearm are connected by a joint structure, wherein,

a first cylinder is arranged in the upper arm; a second cylinder is arranged in the front arm; a pair of connecting discs is arranged in the joint structure; a plurality of guide posts are arranged between the pair of connecting discs, and the two guide posts are respectively fixedly connected with the pair of connecting discs;

the fixed end of the first cylinder is hinged with the mounting seat, and the telescopic end of the first cylinder is connected to the guide pillar;

the telescopic end of the second cylinder is hinged to the guide pillar, the fixed end of the second cylinder is connected with the desktop, and the first cylinder and the second cylinder are connected to different guide pillars to form a parallel lifting mechanism.

Furthermore, the number of the guide columns is three, and the guide columns are uniformly distributed by taking the circle center of the connecting disc as the center.

Furthermore, the connecting line of the connecting points of the guide post and the connecting disc is in an equilateral triangle shape.

The utility model has the advantages of that:

the utility model discloses a double cylinder design in upper arm and the forearm, the cylinder and the articulated design of guide pillar, the position selection design of guide pillar, the quick adjustment desktop displacement of being convenient for carries out position adjustment when realizing the desktop height control, reaches the lift effect of parallel four sides form.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a parallel lifting mechanism comprises a cross shaft support 1, wherein mounting seats 6 are arranged at two ends of the cross shaft support 1, an upper arm 3 and a forearm 4 are mounted on the mounting seats 6, the upper arm 3 and the forearm 4 are connected through a joint structure 5, and a first air cylinder 301 is arranged in the upper arm 3; a second cylinder 401 is arranged in the front arm 4; a pair of connecting discs 501 are arranged in the joint structure 5; a plurality of guide posts 502 which are respectively fixedly connected with the pair of connecting discs 501 are arranged between the pair of connecting discs 501; the fixed end of the first cylinder 301 is hinged with the mounting seat 6, and the telescopic end is connected to the guide post 502; the telescopic end of the second cylinder 401 is hinged on the guide post 502, the fixed end is connected with the table top 2, and the first cylinder 301 and the second cylinder 401 are connected on different guide posts 502 to form a parallel lifting mechanism.

In order to meet the use requirements of different strokes and different displacement requirements, the number of the guide columns 502 is three, and the guide columns are uniformly distributed by taking the circle center of the connecting disc 501 as the center. The connecting line of the connecting points of the guide post 502 and the connecting disc 501 is in an equilateral triangle shape. The first cylinder 301 and the second cylinder 401 can be connected by selecting two different guide posts at will. Under the drive of the first cylinder 301 and the second cylinder 401, the upper arm 3 and the front arm 4 can be extended, retracted and rotated to different degrees, so as to drive the desktop to realize the design requirement of parallel lifting.
