Description

A kind of electrical equipment supporting base

Technical field

The utility model relates to a kind of electrical equipment supporting base, and it is used for household electric appliance are provided support function.

Background technique

Household electric appliance such as television set be fixed with dual mode, a kind of is wall-hanging, and a fixing frame promptly is set on wall, and the fixed hole of television set by the back side is arranged on this fixing frame; Another kind of ground type is exactly that television set props up by a supporting base and stays on floor or the platen.With reference to figure 3 and Fig. 4, known ground type television set supporting base comprises fixing frame 1 ', POM plate 2 ', movable frame 3 ' and coupling shaft 4 ' etc., described fixing frame 1 ' is used for being fastenedly connected with the television set back side, fixing frame 1 ' is connected with POM plate 2 ' and movable frame 3 ' successively by coupling shaft 4 ', by nut 41 ' and 4 ' the sealed connection of coupling shaft, described fixing frame 1 ' can be relative to rotating along horizontal plane with movable frame 3 ', described movable frame 3 ' is provided with curve bath 31 ', curve bath 31 ' the corresponding position on described fixing frame 1 ' and the movable frame 3 ' is provided with limited post 11 ', thereby when fixing frame 1 ' rotates with respect to movable frame 3 ' along continuous straight runs, limited post 11 ' moves in curve bath 31 ' and is used to limit the angle that fixing frame 1 ' rotates with respect to movable frame 3 ', thereby when television set or other electrical equipment were placed on the table top by supporting frame, television set can be done the rotation of several angle with respect to table top.The deficiency of this kind supporting base is: when people want to change the screen of TV set angle, need rotate television set with hand, the fixing frame 1 ' on its supporting base is realized with respect to movable frame 3 ' rotation, use quite inconvenience.

The model utility content

The purpose of this utility model provides a kind of electrical equipment that can make easily and rotates electrical equipment supporting base at any angle along horizontal plane.

The technological scheme that the utility model adopted is such: a kind of electrical equipment supporting base, comprise pedestal, fixing frame, friction plate and whirligig, described whirligig comprises motor, speed reducer, actuation gear, ring gear and electric control system, described motor is located on the fixing frame, the rotating shaft of speed reducer and motor is in transmission connection, actuation gear is located at the speed reducer output terminal, ring gear be located on the pedestal and with the setting of actuation gear engagement driving, seat is wiped sheet and is located on the pedestal, whirligig and fixing frame prop up by friction plate and stay at the pedestal top, electric control system comprises signal transmitter, signal receiver and control circuit, signal receiver is electrically connected with control circuit, and control circuit is electrically connected the forward and reverse that are used to control motor by relay with motor coil.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: launching by signal transmitter just changes or reverse signal, signal receiver receive just change or reverse signal after just changeing or reverse relay adhesive or disconnection by control circuit control, thereby control the motor forward and reverse indirectly, the forward and reverse of motor show that fixing frame is relative to pedestal rotating along horizontal plane, the operator need not with hand rotational fixation frame, the i.e. rotation of remote controlled fixing frame like this.
