Description

Support structure with tilt lock

technical field

The utility model relates to a support structure, in particular to a support structure with an oblique locking function.

Background technique

Flat panel monitors, such as LCD monitors, LCD TVs or plasma TVs, etc., have gradually replaced traditional picture tube (CRT) monitors due to their advantages of light weight, thinness and no radiation. Since liquid crystal and plasma monitors have viewing angle limitations, they are generally provided with at least one rotating shaft structure between them and the base, so that the monitor has the function of adjusting the elevation angle relative to the base.

However, this method cannot provide the monitor's lifting and forward and backward movement functions, that is, the CN 1244852C patent case "monitor with improved tilting structure" (corresponding to the U.S. No. 6,822,857 patent case) as an example, the upper and lower ends of the connecting component are pivotally connected to a main bracket and a base through a main hinge and a base hinge respectively, and the ends of the two auxiliary connecting components are respectively connected to the A supporting structure is formed between the main hinge at the upper end of the connecting component and the base hinge at the lower end; the two auxiliary connecting components can convert the rotational movement of the connecting component relative to the base into the movement of the monitor connected to the main bracket. Tilt movement. In order to support the weight of the monitor, the support structure usually has a torsion spring between the base and the connecting assembly, so that the reaction force of the torsion spring can be offset against the weight of the monitor, so that the user can easily Adjust the height and tilt of the monitor.

The support structure is generally applied to a vertical type. If it is used in a suspended type, the torsion spring cannot support the weight of the monitor horizontally, so that the monitor is pivoted by the main hinge. It is supported by the torsion force formed by the lock between the upper ends of the connecting components. And in order to form the inclination angle positioning function of this main bracket and the connection assembly, as the "positioning structure of the support frame" of the No. M310569 patent case of Taiwan Patent Announcement of China is an example, it is at the upper end of a first support arm and a second support A fixed shaft is horizontally pivoted at the lower end of the arm; in addition, a positioning combination is sleeved on the fixed shaft and is located between the first and second support arms. The positioning combination has a first elastic piece and a second elastic piece. The first and second elastic pieces are combined and fixed to the first and second supporting arms respectively, and at least one first and second positioning portions are arranged around the adjoining surfaces of the first and second elastic pieces at corresponding intervals. Wherein, when the first and second positioning parts are implemented, each can be a bump, or a bump and a groove, so that when the second support arm rotates relative to the first support arm, the second elastic piece can be moved along the The rotation of the first elastic piece makes the protrusions of the first and second positioning parts abut against each other, or the protrusions fall into the grooves, thereby forming a positioning relationship.

However, this case only provides the tilt angle positioning function between the main bracket and the connecting component, but the positioning function is not equivalent to the locking function, that is, if the weight of the monitor is greater than the interference torque of the two protrusions, or greater than the protrusion If the fastening torque with the groove, the positioning function will be lost. The locking function is to form a lock between the main bracket and the connecting component, so that the main bracket can no longer rotate relative to the connecting component, so as to form an oblique locking effect, that is, when the main bracket of the supporting structure is relative to the upper end of the connecting component When rotating to a preset angle of inclination, it can automatically form a lock to prevent the main bracket from being disengaged from the connecting component due to excessive load, thereby losing the function of stagnant positioning. Therefore, how to provide a combination between the main bracket and the connecting component The tilting locking device is a difficult problem that the related industry needs to overcome urgently.

In view of this, the applicant of the present utility model has been engaged in the design, production and sales of rotating shafts and monitor support structures for many years, and has devoted himself to research in order to overcome the lack of only positioning functions between the main bracket and the connecting components of the existing support structures. After repeated experiments and tests, the "support structure with tilt locking function" of the utility model was developed.
