Abstract
The utility model discloses an automatic lifting device of a rack of a liquid crystal display, comprising a base and a fixing plate. The automatic lifting device is characterized in that: a rack lifting mechanism is arranged between the base and the fixing plate; the rack lifting mechanism is connected with a bidirectional motor; the bidirectional motor is connected with an integrated plate; the integrated plate is connected with an upper sensor, a lower sensor and a relay. According to the rack lifting mechanism disclosed by the utility model, one end of the rack is connected with the fixing plate while the other end thereof is inserted into a rack sleeve; the rack sleeve is connected with the base by a support rod. The automatic lifting device has benefit that a user can regulate height of the liquid crystal display in front of a computer, so that the head of the user can move along with the display, thus protecting the neck of the user to be healthy.
Description
Technical field
The utility model relates to a kind of tooth bar apparatus for automatically lifting, particularly a kind of tooth bar apparatus for automatically lifting that is used for liquid crystal display.
Background technique
At present, the supporting frame of liquid crystal display on the market has two kinds, and a kind of is highly nonadjustable fixing support rack, but another kind is the fixing support rack of manual adjustment height.Nonadjustable fixing support rack is highly fixed, and this fixing support rack sees that for a long time screen is unfavorable to the neck of human body, can cause neck injury.But the fixing support rack of manual adjustment, though adjustable height, in using, neck is still motionless relatively, the long-term use also can be caused neck injury.
Summary of the invention
The purpose of this utility model is the tooth bar apparatus for automatically lifting that a kind of liquid crystal display will be provided, and people can be according to demand when using computer, and arbitrarily the height of lifting liquid crystal display makes people's neck be in the most comfortable state.
The utility model is to realize like this, the tooth bar apparatus for automatically lifting of described liquid crystal display, it comprises base, fixed plate, it is characterized in that: be provided with the tooth bar elevator mechanism between base and the fixed plate, the tooth bar elevator mechanism is connected with either-rotation motor, either-rotation motor is connected with integration plate, and integration plate is connected with upper and lower sensor, relay.
Tooth bar elevator mechanism described in the utility model, an end of its tooth bar is connected with fixed plate, and the other end of tooth bar inserts the tooth bar overcoat, and the tooth bar overcoat is connected with base through strut.
The beneficial effects of the utility model are, people are before computer, and the height of regulator solution crystal display makes head with the display device activity automatically, and neck is played a role in health care.
