[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] Example:

[0025] Please combine Figure 1-Figure 5 A digital display screen quick-installation device of the present embodiment is installed on the digital display screen 1. The digital display screen 1 is placed in the cavity of the placement frame 3, and the front and rear surfaces of the placement frame 3 are provided with a plurality of linearly distributed positioning holes 32. A mask 2 is clamped on the top of the placement frame 3, and a plurality of linearly distributed curved portions 22 are provided on the front and rear sides of the bottom of the mask 2. A positioning pin 23 is provided in the curved portion 22. A circular hole is formed by passing through the curved portion 22 from front to back. An annular groove is provided on the positioning pin 23, and it is rotatably installed in the circular hole through the annular groove. The positioning pin 23 is inserted into the positioning hole 32. When the positioning pin 23 is completely separated from the positioning hole 32, the thickness of the curved portion 22 contacts the digital display screen 1, and the positioning pin 23 can be rotated so that the deflection block 25 rotates accordingly.

[0026] The length and width of the outer surface of the mask 2 are completely consistent with the length and width of the outer surface of the placement frame 3. The mask 2 can completely overlap with the outer surface of the placement frame 3, thereby improving the viewing experience.

[0027] A contact frame plate 24 with a rectangular structure is arranged around the lower end of the mask 2. The outward surface of the contact frame plate 24 contacts the inner wall of the placement frame 3, and there is a 3-5mm gap between the inner wall of the contact frame plate 24 and the inner wall of the mask 2. The inner wall of the contact frame plate 24 contacts the side of the digital display screen 1, which is used to limit the digital display screen 1, and at this time, there is a certain gap between the bent portion 22 and the digital display screen 1.

[0028] The front and rear surfaces of the mask 2 are integrally formed with a plurality of equally spaced thickened insert plates 21, the outwardly facing surface of the thickened insert plates 21 being flush with the outer surface of the mask 2, and the thickened insert plates 21 are designed to have sufficient thickness to be connected to the bent portion 22 by screws;

[0029] A plurality of evenly distributed insertion notches 31 are provided above the front and rear surfaces of the placement frame 3 , and a plurality of thickened plug plates 21 are correspondingly plugged into the insertion notches 31 .

[0030] A plurality of evenly distributed installation notches are provided on the front and rear sides of the contact frame plate 24, and the bent portion 22 is placed in the installation notches, and the bent portion 22 is fixed to the inner side of the thickened plug plate 21 by screws. The bent portion 22 is modularly designed to facilitate its replacement. When it is damaged, the entire mask 2 can be used by replacing the bent portion 22;

[0031] There is a 2-3mm gap between the inner surface of the bent portion 22 and the inner surface of the contact frame plate 24. The bent portion 22 can be pressed inward to bend a certain distance so that the positioning pin 23 can be disconnected from the positioning hole 32, thereby facilitating the disassembly of the mask 2.

[0032] A plug-in slot 33 is formed on the placement frame 3 by cutting away a portion of the placement frame 3. The plug-in slot 33 is connected to the plug-in notch 31 and the positioning hole 32.

[0033] A deflection block 25 is provided above the outward side of the locating pin 23, and the deflection block 25 is placed in the insertion groove 33. After the locating pin 23 is disengaged from the locating hole 32, the deflection block 25 is also disengaged from the insertion groove 33. At this time, the deflection block 25 can be rotated a certain angle so that the deflection block 25 is placed behind the locating hole 32, which can block the locating pin 23 and prevent the locating pin 23 from returning to the locating hole 32, thereby facilitating the contact locking of multiple locating pins 23 in sequence.

[0034] The implementation principle of a digital display screen quick-install device in the embodiment of the present application is as follows: when installing, the mask 2 is placed above the placement frame 3, and the positioning pin 23 is located on the inner wall of the placement frame 3 (the deflection block 25 is vertically facing upward at this time), and the mask 2 is pressed downward as a whole. The curved portion 22 is made of plastic, which has a certain elasticity, so that the positioning pin 23 can be placed on the inner wall of the placement frame 3 and slide down along the inner wall. When the positioning pin 23 coincides with the positioning hole 32, the curved portion 22 is subjected to the inward force disappearing and returning to its original state. The positioning pin 23 is clamped into the positioning hole 32 under the action of the curved portion 22, and then fixed;

[0035] When disassembling, use your fingers to press the positioning pin 23 inwards and make the positioning pin 23 disengage from the positioning hole 32, and the deflection block 25 will then disengage from the insertion slot 33. At this time, the curved portion 22 is in contact with the digital display screen 1, so that it will not continue to move backward. Then, the positioning pin 23 is deflected by a certain angle, and the deflection block 25 is placed behind the positioning hole 32, which can block the positioning pin 23 and prevent the positioning pin 23 from returning to the positioning hole 32. After multiple positioning pins 23 are disengaged from the positioning holes 32 in turn, the mask 2 can be removed upwards;

[0036] By providing a plurality of bendable bending portions 22 under the mask 2, and providing positioning pins 23 on the bending portions 22, which can be snapped into the positioning holes 32 of the placement frame 3, the mask 2 and the placement frame 3 can be quickly installed and removed without using related tools such as screwdrivers, thereby improving convenience;

[0037] By setting a thickened plug plate 21 under the mask 2 and connecting the bent portion 22 to the thickened plug plate 21 by screws, the overall modular design is convenient for replacement. When the mask 2 is damaged, the entire mask 2 can be used by replacing the bent portion 22.

[0038] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
