Description

Manual section adjustment of the desk

This creation is about a manual segmented-adjustable lift table, especially a kind that not only makes its overall structure easier and more convenient, but also can effectively reduce the production cost, reduce the burden on users, and can accurately know the use of The height value of the table top and bottom movement adjustment, and in its overall implementation and use, it is an innovative designer of manual section adjustment of the lifting table that increases the practical performance characteristics.

Press, due to the different usage habits and height differences of different users, all kinds of tables are not suitable for every different user. Therefore, some manufacturers have developed the table between the table top and the table legs on both sides of the table. There are air pressure rods respectively to control the rise and fall of the air pressure rods to adjust the height of the table board; however, for this type of structural design, the position of the feet of the general table must be taken into account and the user's usage habits must be considered. , so that the table legs are not set in the middle of the two sides of the table board, so that the air pressure rod is prone to deflection and unsmooth movement during the process of driving the table board to adjust the height. In addition, the movement of the air pressure rods on both sides cannot be To achieve synchronous movement adjustment, it will also cause the table board to move unsmoothly during the height adjustment process.

Therefore, the creator has developed a kind of "table lifting structure" announced on September 1, 2018 No. I662919, which mainly includes the table board, the table legs and the lifting adjustment structure; among which: the table board, its in The bottom ends of the two sides are combined with the table legs at the corresponding positions; the bottom ends of the table legs are provided with a foot seat, a hollow outer tube is assembled on the foot seat, and at least one side of the hollow outer tube is provided with a foot seat. The guide rail, and the two sides of the hollow outer tube that are different from the guide rail are respectively provided with corresponding guide tooth slots and pulley slots, and an inner tube is movably sleeved in the hollow outer tube. The table board is combined; the lifting adjustment structure is respectively sleeved with air pressure rods in the inner tubes of the two table legs, and a guide slide is provided on the outer side of the inner tube corresponding to the guide rail of the hollow outer tube The two sides of the guide slide are equidistantly arranged to form arcs corresponding to the number of phases in contact with the guide rail, and a guide gear is pivoted on the guide tooth slot of the hollow outer tube, and the inner tube corresponds to the guide gear. The guide gear is provided with a guide rack, so that the guide gear is meshed with the guide rack, and a pulley is pivoted on the pulley of the hollow outer tube, and the pulley is in contact with the inner tube.

In addition, the creator has also developed a "Lifting Table Structure" No. M590389 announced on February 11, 2020, which mainly includes a table board, table legs and a lifting control device; among which: the table board is on both sides of the table board. The bottom end is combined with the table foot at the corresponding position; the table foot is provided with a foot seat at the bottom end, a hollow outer tube is assembled on the foot seat, and a hollow inner tube is movably sleeved in the hollow outer tube. A lower guide seat is fixed at the bottom end of the hollow inner tube, and the outer edge of the lower guide seat is provided with a corresponding lower guide pulley, so that the lower guide pulley and the inner edge of the hollow outer tube abut against the upper end of the hollow outer tube is combined and fixed with an upper guide seat, and the inner edge of the upper guide seat is provided with a corresponding upper guide pulley, so that the upper guide pulley is in contact with the outer edge of the hollow inner tube By contacting, the top of the hollow inner tube is combined with the table board; the lifting control device is respectively sleeved with a pneumatic rod in the hollow inner tube of the two table legs, and the bottom end of the pneumatic rod is assembled with It is fixed on the bottom of the hollow outer tube, the upper end of the pneumatic rod is assembled and fixed on the upper end of the hollow inner tube, and a control part is arranged on the top of the pneumatic rod.

However, regardless of the above-mentioned "table lift structure" or "lift table structure" in its actual implementation, it is found that this type of structure has the following disadvantages:

1. These structures are all attached to the inner tube of the two table legs with air pressure rods, so as to use the air pressure rods to drive the table board to rise and fall to adjust the height of use, and the setting of the air pressure rods not only makes the overall structure better. It is complicated and the device cost is higher, and it is relatively incapable of effectively reducing the overall manufacturing cost.
