[0028] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, an edge protection embedded splicing LED display screen of the present invention includes an upper shell 1, a lower shell 2, an LED display screen 4, and a cross beam 3. A plurality of upper shells 1 and lower shells 2 are provided, and the upper shells 1 and the lower shells 2 are fixedly connected to each other through hinge members. After the upper shells 1 and the lower shells 2 are opened, they are both clamped and fixed on the cross beam 3. Adjacent upper shells 1 are detachably connected. A plurality of LED display screens 4 are provided and are respectively arranged in the openings of the upper shells 1 and the lower shells 2. Grooves 24 are provided on the top surfaces of the lower shells 2. Positioning portions 21 protrude from the inner wall surfaces of the grooves 24. Limiting channels 25 are formed between both ends of the positioning portions 21 and the grooves 24. Limiting plates 17 are provided inside the grooves 24. One side of each limiting plate 17 extends to the outside and bends upward to form a connecting plate fixed to the upper shell 1. Limiting portions 19 for tightly pressing the upper shell 1 and the lower shell 2 are protruded from the other side surfaces of the limiting plates 17 opposite to the limiting channels 25.

[0029] In this embodiment, thickening portions 13 protrude from the bottom surfaces inside the upper shells 1. Assembly grooves 9 with openings at the lower ends and both sides are formed inside the thickening portions 13. The upper shells 1 are sleeved on the cross beam 3 through the assembly grooves 9. Connection grooves are provided on the back surfaces of the upper shells 1 opposite to the assembly grooves 9. The inner side surfaces of the connecting plates are closely arranged against the back surfaces of the upper shells 1. Connecting portions 18 protrude from the inner side surfaces of the connecting plates opposite to the connection grooves. The connecting portions 18 are inserted into the connection grooves. The top surfaces of the lower shells 2 are in contact with the bottom surfaces of the cross beam 3.

[0030] In this embodiment, a plurality of mounting portions 11 protrude from the inner wall surfaces of the upper shell 1 and the lower shell 2. Through holes 23 are provided at the centers of the mounting portions 11. One end of each through hole 23 expands outward to form a hidden groove 14 communicating with the outside. Screw holes are provided on the back surface of the LED display screen 4 corresponding to the through holes 23. Fixing bolts 15 are provided in the through holes 23. The bolt rod portions of the fixing bolts 15 are threadedly connected to the screw holes. The bolt heads of the fixing bolts 15 are arranged inside the hidden grooves 14 and are in contact with the inner wall surfaces of the hidden grooves 14. The width of the bolt heads is greater than the inner diameter of the through holes 23. First compression springs 12 are sleeved on the bolt rod portions. One end of each first compression spring 12 is mounted on the mounting portion 11, and the other end is in contact with the back surface of the LED display screen 4. Among them, the LED display screen is fixed in the upper shell and the lower shell by fixing bolts. After the fixing bolts are unscrewed, the LED display screen can be directly taken out of the upper shell and the lower shell, which facilitates disassembly, replacement, and stability of the LED display screen, and increases convenience.

[0031] In this embodiment, a plurality of positioning rods 22 are mounted on one side of the positioning portion 21 facing the limiting plate 17. Positioning holes are provided on the side surface of the limiting plate 17 corresponding to the positioning rods 22. One end of each positioning rod 22 is inserted into the positioning hole. Second compression springs (not shown) are sleeved on the positioning rods 22. One end of each second compression spring is mounted on the positioning portion 21, and the other end is mounted on the limiting plate 17.

[0032] In this embodiment, rectangular grooves 5 are provided on one side surface of the upper shell 1. Slots 8 are provided on the bottom surfaces of the rectangular grooves 5. Rectangular portions 6 protrude from the other side surface of the upper shell 1. Insert portions 7 protrude from the bottom surfaces of the rectangular portions 6. The rectangular portions 6 between adjacent upper shells 1 are inserted into the rectangular grooves 5, and the insert portions 7 are inserted into the slots 8. An avoidance space is formed between the top surface of the rectangular portion 6 and the top surface of the rectangular groove 5 for the rectangular portion 6 to move upward and the insert portion 7 to move out of the slot 8.

[0033] Among them, when splicing adjacent upper shells, the rectangular portion needs to be aligned with the adjacent rectangular groove. After the upper shell moves in the direction of the cross beam, the rectangular portion can be inserted into the rectangular groove. After the upper shell moves downward and is sleeved on the cross beam, the insert portion can be inserted into the slot, so that adjacent upper shells are spliced together, increasing the tightness between adjacent LED display screens.

[0034] In this embodiment, a plurality of buffer blocks are mounted on the screen of the LED display screen 4. The buffer blocks are all made of transparent silicone material. When the LED display screens approach each other, the buffer blocks come into contact first, avoiding extrusion between the screens, preventing damage to the screens due to pressure, increasing safety, and since the buffer blocks are made of transparent silicone, it does not affect the viewing of the content on the screen.

[0035] In this embodiment, the widths of the assembly grooves 9 are all matched with the thickness of the cross beam 3, and the heights of the assembly grooves 9 are all matched with the height of the cross beam 3, which increases the matching degree between the assembly grooves and the cross beam, avoids the shaking of the upper shell, and increases the stability after installation.

[0036] In this embodiment, a buffer space for the LED display screen 4 to retreat is formed between the back surface of the LED display screen 4 and the installation part 11; both the upper shell 1 and the lower shell 2 are made of metal materials, which increases the firmness and also enables the upper shell and the lower shell to play a supporting role and achieve a fixing effect.

[0037] During installation, the upper shell and the lower shell can be opened around the hinge in the middle, making the upper shell vertical and the lower shell horizontally arranged, and the two are in an "L" - shaped structure. At this time, the assembly groove at the lower end of the upper shell is in an open state, enabling the upper shell to be directly sleeved on the cross beam through the assembly groove. After sleeving, the lower shell can be pulled outwards again until the upper shell and the lower shell are straight. After the lower shell is opened, the top surface of the lower shell can squeeze the cross beam, fixing the upper shell and the lower shell on the cross beam in a clamping manner, increasing the stability.

[0038] Among them, in order to prevent the lower shell from closing inwards, the connecting plate can be pulled outwards so that the connecting plate is located behind the upper shell. After releasing the connecting plate, the second compression spring can drive the connecting plate to move towards the upper shell through its rebound until the connecting part is inserted into the connecting groove of the upper shell, connecting the upper shell and the lower shell, preventing the lower shell from closing inwards by itself, and facilitating the installation of the LED display screen.

[0039] After the LED display screen is installed, since a buffer space for the LED display screen to retreat is formed between the LED display screen and the installation part, when the front of the LED display screen is impacted, the LED display screen can move backward along the inner wall of the upper shell or the lower shell. The movement of the LED display screen can squeeze the first compression spring, and the rebound of the first compression spring can play a buffering role, increasing the safety of the LED display screen and reducing the probability of screen damage.

[0040] Among them, when not in use, the connecting plate can be pulled outwards so that the connecting part on the connecting plate is pulled out from the connecting groove of the upper shell. After losing the connection of the connecting plate, the lower shell can close inwards. After the lower shell is removed from below the cross beam, the upper shell can be directly taken off the cross beam upwards, facilitating disassembly.

[0041] Moreover, the upper shell and the lower shell can be closed. During the closing process, the LED display screens will be squeezed first. After being pressed, they can retract into the interior of the upper shell and the lower shell. As the upper shell and the lower shell continue to close, finally, the upper shell and the lower shell can touch each other, sealing the LED display screen inside the upper shell and the lower shell, effectively covering it, avoiding being impacted by the outside world, and also facilitating transportation and storage.

[0042] Wherein, after the upper shell and the lower shell are completely closed, since the second compression spring was in a stretched state before, the second compression spring can drive the limit plate and the limiting portion to move leftward until the limiting portion extends out of the limiting channel and abuts against the end face of the upper shell. Through the limiting portion, the upper shell and the lower shell can be tightly abutted, so that the upper shell and the lower shell cannot be opened around the hinge, which increases the sealing effect and also facilitates the closing operation.

[0043] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
