Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the functions of the invention easy to understand, the invention is further explained by combining the specific embodiments.

As shown in fig. 1 to 5, an outdoor display screen comprises a display screen box 1, a display screen 2, a main motor 3, a turbine 4, a bracket 5 and a curtain protection box 6; display screen 2 is located display screen case 1 and rather than sliding connection, 3 fixed connection of main motor are on the bottom plate of display screen case 1, and the output shaft keyed joint of main motor 3 has connecting rod 30, fixedly connected with worm 32 on the connecting rod 30, worm 32 and the meshing of turbine 4, turbine 4 rotates and connects on 1 interior curb plate of display screen case, and 4 interior threaded connection that go back of turbine has telescopic strut 40, telescopic strut 40's outer end fixed connection is at the 2 backs of display screen, support 5 is equipped with four groups and all fixed connection on the curb plate of display screen case 1, and support 5 sliding connection has branch 50, branch 50 passes through connecting plate 51 fixed connection at the 2 backs of display screen. The main motor 3 and the auxiliary motor 7 are servo motors, when the display screen 2 is used, the main motor 3 is started, the main motor 3 drives the worm 32 to rotate positively to drive the turbine 4 to rotate positively, the turbine 4 rotates positively to screw out the telescopic support column 40, and the display screen 2 is pushed out, so that the front surface of the display screen 2 is flush with the front surface of the display screen box 1. When the display screen 2 is used (for example, when no person is in the night), the main motor 3 is started, the main motor 3 reversely rotates to drive the worm 32 to reversely rotate so as to drive the turbine 4 to reversely rotate, the turbine 4 reversely rotates to screw the telescopic support 40 in, and then the display screen 2 is pulled back. In the above process, the rod 51 will slide in and out along the bracket 5 following the display screen 2, and the bracket 5 and the rod 51 function to keep the display screen 2 stable.

Preferably, the curtain protection box 6 is fixedly connected to the top of the display screen box 1, the bottom of the curtain protection box 6 is fixedly connected with a curtain protection box bottom plate 60, a curtain protection notch 61 is formed in the curtain protection box bottom plate 60, an auxiliary motor 7, a main roller shutter roller 8, an auxiliary roller shutter roller 80 and a curtain protection 9 are further arranged in the curtain protection box 6, an output shaft of the auxiliary motor 7 is connected with the main roller shutter roller 8 through a belt, the main roller shutter roller 8 and the auxiliary roller shutter roller 80 are both rotatably connected with the curtain protection box 6, and the curtain protection 9 is wound on the main roller shutter roller 8 and the auxiliary roller shutter roller 80. When the display screen 2 is used, before the main motor 3 is started, the auxiliary motor 7 rotates forwards to drive the main roller shutter roller 8 to rotate forwards to wind and store the protective curtain 9, and the protective curtain 9 is retracted upwards to expose the display screen 2. When the display screen 2 is used (for example, when no person is in the night), after the display screen 2 retracts, the auxiliary motor 7 is started, the auxiliary motor 7 reversely rotates to drive the main roller shutter roller 8 to reversely rotate, the protective curtain 9 is discharged, the protective curtain 9 falls downwards, and finally the display screen 2 is covered.

Preferably, the connecting rod 30 is rotatably connected to the inner side plate of the display screen box 1 through a connecting rod bracket 31. The connecting rod bracket 31 serves to maintain the stability of the connecting rod 30.

Preferably, the lower end of the protective curtain 9 passes through the protective curtain notch 61 and is fixedly connected to the bearing rod 90, the two side walls of the display screen box 1 are provided with bearing rod grooves 10, and the two ends of the bearing rod 90 are located in the bearing rod grooves 10 and are in sliding connection. The bearing bar 90 at the bottom of the curtain 9 is used to keep the curtain 9 stable and not flying with the wind.

Preferably, a strut groove 52 is formed in the bracket 5, and the strut 50 is located in the strut groove 52 and slidably connected thereto. The bracket 5 is arranged in the support rod groove 52 and can only slide in and out along the support rod groove 52, so that the bracket 5 is limited and maintained stably, and the stability of the display screen 2 during extension and retraction is further maintained.

The specific implementation mode and principle are as follows:

when the display screen 2 is used, before the main motor 3 is started, the auxiliary motor 7 rotates forwards to drive the main roller shutter roller 8 to rotate forwards to wind and store the protective curtain 9, and the protective curtain 9 is retracted upwards to expose the display screen 2; and then the main motor 3 is started, the main motor 3 rotates forwards to drive the worm 32 to rotate forwards so as to drive the turbine 4 to rotate forwards, the turbine 4 rotates forwards to screw out the telescopic support column 40, and the display screen 2 is pushed out, so that the front surface of the display screen 2 is flush with the front surface of the display screen box 1.

When the display screen 2 is used well (for example, late at night, when the typhoon rainstorm is blown or the midday sunlight is strong, there is no pedestrian in these time points often outdoors, the display screen 2 does not need to be used either), the main motor 3 is started first, the main motor 3 drives the worm 32 to rotate reversely and then drives the turbine 4 to rotate reversely, the turbine 4 rotates reversely to advance the telescopic strut 40, and then the display screen 2 is pulled back, after the display screen 2 retracts, the auxiliary motor 7 is started again, the auxiliary motor 7 drives the main roller shutter roller 8 to rotate reversely to release the protective curtain 9, the protective curtain 9 falls downwards, and finally the display screen 2 is covered.

When the display screen 2 is not used, the display screen 2 is completely retracted into the display screen box 1 and covered by the protective curtain 9, so that the display screen 2 is fully protected.

Based on the above, the utility model discloses simple structure, it is nimble to use, can protect the display screen through setting up the display screen case, still sets up the flexible motor of drive display screen, stretches out when making the display screen use, not time spent withdrawal improves the protection effect, and sets up the protection curtain that can go up and down and further protects the display screen, avoids it to receive the wind and rain to drench and sunshine insolate.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
