Description

Technical Field

[0001] The utility model relates to the technical field of advertising machine splicing machine bases, in particular to a fast-splicing advertising machine which is easy to move. Background Art

[0002] A splicing advertising machine is an advertising display device that automatically splices multiple advertising contents and generates a coherent and complete advertising display. The splicing advertising machine is mainly composed of liquid crystal units, control circuits, drive circuits and other parts. The liquid crystal unit is usually placed in two parallel glass substrates and is composed of TFT (thin film transistor) and color filters. The control circuit and drive circuit are responsible for controlling the polarization of liquid crystal molecules and the refraction of light to achieve the display of images. The working principle of the splicing advertising machine is based on liquid crystal display technology. When the electrodes in the splicing advertising machine generate an electric field, the liquid crystal molecules are distorted, and the light passing through them is refracted regularly, then filtered through the filter layer and displayed on the screen. By controlling the polarization state of the liquid crystal molecules, precise control of each pixel can be achieved, resulting in a clear and delicate image.

[0003] Traditional splicing advertising machines are pre-spliced ​​during installation, and after debugging, a large screen is formed to solve the installation and other problems caused by a whole screen.

[0028] The rotating side of the clamping block 12 is connected to the top surface of the splicing base 11 through a torsion hinge, and the top surface of the clamping block 12 is initially flush with the top surface of the splicing base 11. After the clamping block 12 rotates upward, the torsion hinge generates a downward restoring force, so that the clamping block 12 can fit the docking device 2 tightly.

[0029] Furthermore, the docking device 2 includes a sliding block 21 , a clamping groove 22 , a push-pull block 23 and a connecting rod 24 , and a long hole is opened on the side wall of the splicing base 11 .

[0030] The side wall of the sliding block 21 is connected to one end of the connecting rod 24 , and the other end of the connecting rod 24 passes through the long hole on the side wall of the splicing base 11 to connect to the push-pull block 23 . The top surface of the sliding block 21 is provided with the clamping groove 22 .

[0031] The push-pull block 23 has a screw hole at its end surface opposite to the connecting rod 24. Figure 3 and Figure 4 As shown, Figure 4 The docking device 2 is in a specified position state. When the docking device 2 is in this position, the positioning hole provided on the side wall of the splicing base 11 corresponds to the screw hole of the push-pull block 23.

[0032] When it is not needed in normal times, the docking device 2 can be pushed into the splicing base 11, and the outer side surface of the docking device 2 is flush with the side surface of the splicing base 11. Figure 7 This design can reduce the floor space occupied when the advertising machine of the present application is used alone.

[0033] Furthermore, the lifting device 3 includes a rotating cylinder 31 , a screw rod 32 and a gear ring 33 .

[0040] Working principle:

[0041] The staff pushes the push-pull block 23 to push the entire docking device 2 to the specified position, and positions the screw holes of the push-pull block 23 with the positioning holes of the splicing base 11 through bolts. At this time, the advertising machine of this application is pushed to bring the two advertising machines that need to be spliced ​​closer.

[0042] During splicing, the sliding block 21 of one of the advertising machines is inserted into the docking port of the splicing base 11 of the other advertising machine, the card block 12 of the other advertising machine is lifted up, the card block 12 is returned to the normal position due to the hinge force, and the card block 12 is engaged in the engaging groove 22. The docking of the display screen 41 is completed by aligning the socket 412 of one of the advertising machines with the plug 411 of the other advertising machine, so that the display screens 41 on the two advertising machines are connected.

[0043] When disassembling, it is only necessary to push the block 12 upwards and pull out the docking device 2 of one of the advertising machines.
