Description

Table lifting structure

The present invention relates to a table lifting structure, in particular to a table that allows the inner tube of the table foot to move synchronously and unbiasedly in the hollow outer tube to facilitate adjustment of the table combined on the inner tube of the table leg. The height of the board is an innovative designer of the table lifting structure that is suitable for different users to use, and which has more practical functions in its overall application.

Press, people often use a variety of tables in their daily lives. All kinds of tables are generally used for people to put various items on them for dining, office, study and other activities, so that a variety of tables are in People occupy a very important position in life and can be said to be an indispensable necessity in people's life.

Due to the different usage habits and height differences of different users, various types of tables cannot be applied to each different user. Therefore, the manufacturer has developed a table height adjustment structure for the table of the table. A gas pressure bar is respectively arranged between the legs of the two sides, so that when the rise and fall of the gas pressure bar are controlled, the purpose of adjusting the height of the table can be adjusted, so that the table can be applied to different users.

However, although the above-mentioned table height lifting adjustment structure can achieve the expected effect of adjusting the height of the table board, it is also found in its actual implementation, because it is provided with a gas pressure bar between the two sides of the table board and the table legs to utilize The rise and fall of the gas pressure bar adjusts the height of the table, and the position of the general table legs is such that the position of the user's feet and the user's habits must be taken into consideration, so that the table legs are not disposed at the middle of both sides of the table, resulting in During the process of height adjustment of the table, the air pressure bar is easy to be deflected and the movement is not smooth. The movement of the air pressure bar on both sides can not achieve the synchronous movement adjustment, which also causes the table to be used at the height. During the adjustment process, there is a situation in which the movement is not smooth, which makes the structure extremely inconvenient in operation and use, so that the structure still has room for improvement in the overall design.
