The utility model relates to a positioning structure of a sliding seat, in particular to a structure in which a sliding part can be moved up and down and positioned by using a lead screw.

Background technique

China Taiwan New Patent No. 588843 discloses a special elevator for LCD screens. It is provided with an opening on the surface of the wall cabinet or table body to accommodate the elevator containing the LCD screen. There is a lead screw at both ends of the elevator. Make it link a straddling platform between the two lead screws, the straddle platform is used to place the LCD screen, and the elevator also includes a set of belts set in the two lead screws, so that the belt set can When the operation is started, the LCD screen is hidden inside the opening on the wall cabinet or the table body, and when the electrical switch is activated to cause the belt set to move, the straddling platform and the LCD screen are exposed on the wall cabinet or the table body. The opening is provided for use, so that when the liquid crystal screen is hidden, it does not take up any space at all and has a beautiful visual effect.

The transmission and positioning of the above-mentioned lifting structure is to use the belt set to drive the two lead screws, which mainly lies in the storage of the whole set of LCD screens, so the structure is different from the general liquid crystal screen lifting structure using constant force springs.

In addition, the adjustable lifting support device disclosed in Taiwan Model Patent No. M348460 is composed of an outer tube, an inner tube, springs with at least a certain force, a base and a support seat. A base is fixed at the bottom of the outer tube, and an inner tube is sheathed on the top thereof. The two ends of the spring with at least a certain force are respectively arranged on the top edge of the outer tube and the bottom of the inner tube, and the supporting seat is pivotally arranged on the top of the inner tube. Its front is further connected with a supported object. At least one pair of outer walls of the inner tube is preset with an outer tube slider corresponding to the inner wall of the outer tube, and an inner tube slider is provided at a position opposite to the appearance sliding key, and the outer and inner tube sliders are sleeved to form a slide rail structure. In this way, the weight of the supported object is offset by the rebound force of the constant force spring, so that the user can conveniently adjust the height of the inner tube relative to the outer tube.

The positioning of the above lifting structure is to use the constant force spring to provide a resistance to resist the gravity of the supported object. Assuming that the weight of the supported object is W, and the elastic force system of the constant force spring is F, when W is greater than F, the outer tube will down to a balanced state, and when F is greater than W, the outer tube will rise to another balanced state. Therefore, if a user has adjusted the height of the lifting base according to his preference and viewing angle, when the supported object is erected on it On the supporting seat, it is very possible that the height of the outer tube cannot reach the height that the user originally hoped to achieve because the weight of the supported object is greater or less than the elastic force of the constant force spring, causing more troubles for the user in use.

In view of this, the present inventor aimed at the many defects and inconveniences caused by the imperfect structural design of the above-mentioned shoe body, and deeply conceived, and actively researched and improved the trial production to develop and design this creation.
