The utility model provides an LED display screen protection frame which comprises:

referring to fig. 1, an inclined support plate 3 is arranged at the top of a protective ceiling 1, an eva elastic sponge 4 is arranged at the side of the inclined support plate 3 with higher inclined point, and a sliding piece 5 is arranged at the upper side of the inclined support plate 3;

in consideration of the condition that articles fall from the protective ceiling 1 so that the falling front side causes secondary collision on a screen, the top structure of the protective ceiling 1 is optimized in the prior art;

referring to fig. 1, an inclined support plate 3 is disposed on the upper side of a protective ceiling 1, and an eva elastic sponge 4 is disposed on the highest position of the inclined support plate 3, when a falling object is present, the eva elastic sponge 4 is located at a high position and contacts with the falling object before the falling object;

however, when the eva elastic sponge 4 is designed, the inclined surface intersecting the inclined support plate 3 is also designed in synchronization, so that the dropping object moves toward the inclined surface of the eva elastic sponge 4 and the inclined arc of the inclined support plate 3;

referring to fig. 1, considering that a blocking condition occurs during the falling, two sets of sliding members 5 are arranged on the inclined surface of the falling to push the falling to move in an inclined direction;

the inclined radian of the two groups of sliding parts 5 is the same as that of the inclined supporting plate 3, and the two groups of sliding parts are synchronously arranged to move to one side, so that the falling objects are pushed to move forwards;

for the installation of two sides of the sliding piece 5, the sliding piece 5 is embedded on the upper side of the inclined supporting plate 3, one sliding piece 5 consists of six circular shafts, two sides of each circular shaft are connected with the inner side wall embedded in the inclined supporting plate 3 through a rotating shaft, and the gap phase difference between each circular shaft is smaller, so that the situation that the branches and leaves falling from the gap are blocked is reduced;

referring to fig. 2-5, a supporting framework 6 is fixedly connected to the bottom of the protective ceiling 1, a movable block 7 is arranged at the bottom of the supporting framework 6, and a long rod 8 is arranged at the bottom of the movable block 7;

the two side supporting structures in the prior art are designed to be mutually movable, so that when the top is struck by a falling object, the movable block 7 and the long rod 8 are caused to form movement, and the impact frequency of the synchronous structure of the display screen is slowed down;

six connecting rods 9 are synchronously designed around the inserting end of the movable block 7, so that stability is improved when the movable block 7 is positioned in the long rod 8 to move;

meanwhile, in order to meet the working requirements of resetting and shock absorption when the movable block 7 and the long rod 8 move, a resetting spring 10 is arranged on each connecting rod 9, and the upper side and the lower side of the resetting spring 10 are connected with the movable block 7 and the long rod 8, so that the structure of the movable block is understood by referring to fig. 5;

six damping springs 11 which are symmetrical to the connecting rod 9 are arranged at the bottommost position of the inner cavity of the long rod 8, the damping springs 11 shake up and down due to collision when the movable block 7 is positioned in the long rod 8 and transmit weighing force to the long rod 8, the damping springs 11 achieve collision between the two, and the display screen 2 is connected with the long rod 8 through the mounting piece 13, so that the display screen 2 is also involved when the long rod 8 is stressed, and the situation that the display screen 2 is impacted and has shatter is relieved by the operation between the damping springs 11 and the reset spring 10;

wherein in the connection between the long rod 8 and the movable block 7, a connecting rod 9 is arranged for controlling the movement of a return spring 10, and simultaneously, the stability of the connection of the long rod 8 and the movable block 7 can be maintained;

referring to fig. 2-3, an inner hole 12 is formed at the symmetrical position of the lower sides of the six groups of connecting rods 9, so that the inner part of the inner hole 12 is made of wear-resistant plastic, thereby reducing the noise generated when the connecting rods 9 collide downwards.

In the utility model, the working steps of the device are as follows:

1. firstly, a protective shielding body is formed by a display screen 2 which is shielded from the upper side to the lower side of a protective ceiling 1, and when an object falls down to the protective ceiling 1, the protective shielding body contacts an eva elastic sponge 4, so that certain impact noise is relieved;

2. secondly, according to the gradient design of the inclined supporting plate 3, falling objects are promoted to fall to the rear side of the display screen 2, and auxiliary movement is carried out through the sliding piece 5 in the falling process, so that the falling objects are removed;

3. then, during the falling period, the movable block 7 is positioned on the long rod 8 to move up and down, and the gravity applied to the display screen 2 on the long rod 8 by the movable block 7 is slowed down by matching the reset spring 10 and the damping spring 11, so that the display screen 2 is prevented from being cracked;

4. finally, when the movable block 7 moves inside the long rod 8, the connecting rod 9 on the movable block 7 can also be located inside the long rod 8 to move up and down to maintain stability between the two, and an inner trap hole 12 is formed in the moving bottom of the connecting rod 9 to avoid large impact sound when the connecting rod 9 is located at the lower side for impact.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be appreciated by persons skilled in the art that the present utility model is not limited to the embodiments described above, but is capable of numerous variations and modifications without departing from the spirit and scope of the utility model as hereinafter claimed.
