Description

Technical Field

[0001] The invention relates to a three-dimensional display curtain wall, belonging to advertising equipment. Background Art

[0002] The existing matrix advertising machine consists of multiple telescopic units, with a display screen set in front of the telescopic unit. Each telescopic unit is driven by a motor to telescope forward and backward. However, the current advertising machine has the following disadvantages: 1. The motor must rotate right to move forward and reverse to retract. When the display screen displays the picture, the visual surface is facing straight ahead. The telescopic effect cannot be clearly seen from a distance, and the three-dimensional sense is poor.

[0003] A flip-board advertising machine is a device that is composed of many drawing boards with fixed pictures in a horizontal and vertical combination. The pictures are usually two or three, and only two to three pictures can be displayed. To change the picture content, all the slides of the device need to be replaced, which has high operating costs and low advertising returns. Summary of the invention

[0004] The present invention provides a three-dimensional display curtain wall, which realizes a certain angle change while the display screen is telescopically changed, presenting a more beautiful wave change effect.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] The three-dimensional display curtain wall includes a rectangular flap with a display screen on the side thereof. The flap is fixed to a vertical curtain wall frame through a hinge axis in the middle position. A plurality of flaps are arranged side by side horizontally and vertically to form a curtain wall. A deflection mechanism is also provided between the flap and the curtain wall frame. The deflection mechanism drives the flap to swing around the hinge axis, and the swinging range is parallel to the curtain wall frame or perpendicular to the curtain wall frame.

[0007] Preferably, the flap is hinged at the front end of the telescopic box, the telescopic box is arranged on the curtain wall frame, the telescopic box is provided with a telescopic drive mechanism and multiple sets of guide pulleys, the telescopic drive mechanism drives the telescopic box to extend and retract, and the deflection mechanism and the telescopic drive mechanism use the same motor as a power source.

[0008] Preferably, the deflection mechanism includes a motor retraction, a rotating eccentric wheel retraction is arranged at the output end of the motor retraction, a swing guide rod retraction is arranged at the end of the rotating eccentric wheel retraction, the front end of the swing guide rod retraction is hinged to the rear part of the flap, and the hinge point is located on the retraction side of the hinge shaft.

[0009] Preferably, the linear telescopic drive mechanism retracts into a scissors-type telescopic mechanism, the front end of the scissors-type telescopic mechanism is hinged to one end of the telescopic swing rod, the other end of the telescopic swing rod is hinged to the retraction of the rotating eccentric wheel, and the hinge point of the telescopic swing rod on the retraction of the rotating eccentric wheel is coaxial with the hinge point of the retraction of the swing guide rod.

[0010] Preferably, the front end face of the telescopic box body is retracted with two parallel support plates, the retraction length of the support plates is greater than the arc radius swept by the flap when it retracts and rotates, both ends of the hinge axis of the flap are arranged on the support plates, the swing range of the flap is between the two support plates, the retraction position of the swing guide rod is hinged to the flap retraction is in the middle of the retraction of the two parallel support plates, the front end face of the telescopic box body is provided with a swing groove, the motor retraction is arranged inside the retraction of the telescopic box body, and the swing guide rod retracts through the swing groove.

[0011] Preferably, both ends of the retracted swing guide rod are provided with obtuse angle bends, and the two bends are located on the same side of the retracted middle portion of the swing guide rod.

[0012] Preferably, the scissor-type telescopic mechanism is replaced by one of a screw-nut mechanism, a rack-and-pinion mechanism, an electric cylinder, and a synchronous belt mechanism.

[0013] The advantages of the present invention are:

[0014] Using a flip motor to rotate in one direction, the display screen can be extended and retracted at the same time, and the screen can swing between 90 degrees or other angles, making the visual three-dimensional sense stronger;

[0015] The screen can stretch and swing to show a wave-like effect, enhancing the attractiveness of the content on the display.

[0016] The device uses a motor to drive the extension and retraction, and at the same time passes through an eccentric wheel, a connecting rod and a cross mechanism to achieve extension and retraction and drive the screen to change its angle. The existing matrix retractable advertising machine directly adds a flap mechanism, and the manufacturing cost is low. BRIEF DESCRIPTION OF THE DRAWINGS
