Description

Lifting table structure

This creation relates to a lifting table structure, in particular, it not only allows the table board to move smoothly up and down without deflection to adjust the use height, so as to achieve the purpose of being suitable for different users to use, and is composed of the overall structure The design is simpler, which makes it more convenient for the combination of the design, and the innovative designer of the lifting table structure to increase the practical efficiency of the overall implementation.

Press, people often use all kinds of tables in daily life, and due to the different usage habits and height differences of different users, all kinds of tables are not suitable for every different user, so there are The industry has developed a table height adjustment structure, which is equipped with air pressure rods between the table board of the table and the legs of the two sides, so that when the pressure bar is controlled to rise and fall, the height of the table board can be adjusted. The purpose is to make the table suitable for different users.

However, this type of structural design uses the lifting and lowering of the air pressure bar to adjust the height of the table board. Since the position of the general table legs must take into account the user's feet and user habits, the table legs are not set on the table board The middle position of the two sides causes the air pressure rod to easily deflect and move smoothly during the height adjustment of the table board. In addition, the movement of the air pressure rods on both sides can not achieve synchronous movement adjustment, which will also cause The table board may not move smoothly during the height adjustment process.

Therefore, the creator has developed a "table lifting structure" No. 1071117593, which was applied for and approved on May 23, 2018. It mainly includes a table board, table legs and lifting adjustment structure; among them: the table The board is combined with the table legs at corresponding positions on the bottom ends of the two sides; the table legs are provided with a foot seat at the bottom end, and a hollow outer tube is arranged on the foot seat, and at least one of the hollow outer tubes A guide rail is provided inside the side, and on the two sides of the hollow outer tube different from the guide rail, corresponding guide tooth slots and pulley slots are respectively penetrated, and a movable sleeve is provided in the hollow outer tube with an inner tube. The top of the inner tube is combined with the table board; the lifting adjustment structure is provided with an air pressure rod in each of the two inner tubes of the table legs, and the guide rail corresponding to the hollow outer tube is provided outside the inner tube There is a guide slideway, the guide slideway is equidistantly arranged on both sides to form an arc portion corresponding to the number of phases to contact the guide rail, and the guide slot of the hollow outer tube is provided with a guide gear and a guide gear. A guide rack is provided on the inner tube corresponding to the guide gear, so that the guide gear meshes with the guide rack, and a pulley is slotted on the pulley slot of the hollow outer tube, and the pulley is in contact with the inner tube.

However, although the above-mentioned "table lifting structure" can achieve the expected effect of adjusting the height of the use of the table board, it is also found in its actual implementation that the structure is provided with a guide rail inside the hollow outer tube, and a corresponding guide rail is provided on the inner tube There is a guide chute, and there is a meshing guide gear and the guide rack between the hollow outer tube and the inner tube, and at the same time, a pulley is provided in the hollow outer tube to contact the inner tube, resulting in a more overall design The complexity is not only relatively inconvenient in terms of its combination, but also increases the probability of damage and manufacturing costs, so that the structure still has room for improvement in the overall design.
