Description

Table lifting structure

The invention relates to a table lifting structure, in particular to a table leg inner tube which can move smoothly up and down in a hollow outer tube synchronously, so as to conveniently adjust the table combined with the table leg inner tube The height of the board achieves the purpose of being suitable for different users to use, and it has more practical efficiency characteristics in its overall application.

Press, people often use all kinds of tables in daily life. All kinds of tables are generally for people to put various items on them for dining, office, learning and other activities, making all kinds of tables in People occupy an extremely important position in life, which can be said to be an indispensable necessity in people's lives.

Due to the different usage habits and height differences of different users, various types of tables are not suitable for every different user. Therefore, some people have developed a table height adjustment structure for the table board Air pressure rods are respectively arranged between the table legs on both sides, so that when controlling the rise and fall of the air pressure rod, the purpose of adjusting the use height of the table board can be achieved, so that the table can be suitable for different users.

However, although the above table height adjustment structure can achieve the expected effect of adjusting the use height of the table board, it has also been found in its actual use because it is provided with air pressure rods between the two sides of the table board and the table legs to use The lifting and lowering of the air pressure bar adjusts the height of the table board, and the general position of the table legs must take into account the position of the user's feet and the user's habits, so that the table legs are not set at the middle position on both sides of the table board, resulting in In the process of driving the table board to adjust the height, the air bar is easy to be skewed and the movement is not smooth. In addition, the movement of the air bar on both sides can not achieve the simultaneous movement adjustment, and it will also cause the table board to use the height During the adjustment process, the movement is not smooth, which makes the structure very inconvenient in operation and use, so that there is still room for improvement in the overall design of the structure.
