Description

Technical Field

[0001] The utility model relates to the technical field of LED screen transportation, in particular to a protective device for LED screen transportation which is easy to install. Background Art

[0002] In the 1970s, the earliest GaP and GaAsP homojunction red, yellow, and green low-luminous efficiency LEDs began to be used for indicator lights, digital and text displays. Since then, LEDs have entered a variety of application fields, including aerospace, aircraft, automobiles, industrial applications, communications, consumer products, etc., covering all sectors of the national economy and thousands of households. By 1996, the sales of LEDs in the world had reached several billion US dollars.

[0003] LED arrays can replace incandescent lamps with a power of less than 150W. For many applications, incandescent lamps use filters to obtain red, orange, green and blue, while ultra-high brightness LEDs can obtain the same colors. In recent years, ultra-high brightness LEDs made of AlGaInP and InGaN materials combine multiple (red, blue, green) ultra-high brightness LED chips together to obtain various colors without filters. Including red, orange, yellow, green, and blue, its luminous efficiency has now exceeded that of incandescent lamps and is approaching that of fluorescent lamps.

[0004] The existing LED screen transportation protection devices on the market that are easy to install have weak functionality during use. During the transportation protection of the LED screen, the traditional transportation protection device does not protect the inside of the screen tightly enough, resulting in dust. When the screen is in use, the display is not clear or even damaged.

[0005] Therefore, it is necessary to provide a protective device for transporting LED screens that is easy to install to solve the above technical problems. Utility Model Content

A placement plate 8 is provided above the receiving plate 1 and on the opposite side of the two mounting plates 2. The outer walls of the two screws 3 are threadedly connected to the inner wall of the sleeve 5, so that the protective cover 6 fixedly connected to the sleeve 5 and the outer wall of the sleeve 5 can be driven up and down when the screw 3 rotates.

[0023] Multiple placement grooves 9 for placing LED screens are provided on both sides of the outer wall of the placement plate 8, and multiple rotating shafts 10 are integrated on both sides of the outer walls of the multiple placement grooves 9. The outer walls of the multiple rotating shafts 10 are rotatably connected with clips 11 for fixing and limiting the LED screen. The rotation of the clips 11 can conveniently fix the LED screen inside the placement groove 9.

[0024] Cotton pads 12 are arranged inside the multiple placement grooves 9 to provide buffering protection for the LED screen. A first gear 13 for rotation is arranged at the bottom axis of the two screws 3.

[0030] Compared with the related art, the LED screen transportation protection device provided by the utility model which is easy to install has the following beneficial effects:

[0031] The traditional LED screen transportation protection device which is easy to install has weak functionality during operation. In the process of transporting and protecting the LED screen, dust appears inside the screen due to insufficient protection. When the screen is used, the display is unclear or even damaged. In this device, when the LED screen is placed in the placement slot 9, the motor 16 is turned on. The output shaft of the motor 16 is fixedly connected with a rotating rod 17. The outside of the rotating rod 17 is fixedly connected with two second gears 18, thereby driving the two second gears 18 to rotate. The outer walls of the two second gears 18 are meshed with the outer walls of the first gear 13. Two screws 3 are fixedly connected at the axis of the two first gears 13. The outer walls of the two screws 3 are provided with sliding sleeves 5. The opposite side of the outer walls of the two sliding sleeves 5 is fixedly connected with a protective cover 6. Therefore, the first gear 13 drives the two screws 3 to rotate and then drives the protective cover 6 fixedly connected with the sliding sleeve 5 to rise and fall.
