[0030] The utility model is described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-3As shown, an aluminum bracket for an LED screen that is easy to maintain includes a support base 10 and a support frame 1 installed on the top of the support base 10, the support frame 1 includes a plurality of aluminum support bars formed by aluminum material, the plurality of aluminum support bars are vertically spliced ​​into the support frame 1, the aluminum support bars are formed with adjustment grooves 13 along the length direction, the adjustment grooves 13 are slidably installed with a plurality of connection blocks 14 connected to the screen, at least one of the connection blocks 14 is installed with a suction cup 15 for adsorbing the back of the screen, at least one of the connection blocks 14 is installed with an embedding block 16 that can be embedded into the back of the screen.

[0032] The support base 10 and the support frame 1 made of aluminum can be lightweight and reduce weight; when the support frame 1 is connected to the screen, the position of the connection block 14 can be moved according to the model of different screens, so that the suction cup 15 and the embedded block 16 can be connected to the corresponding position of the screen to achieve multi-point support, and the embedded block 16 can further improve the connection stability with the suction cup 15, and it is easy to disassemble and convenient to replace the screen;

[0033] A hinge assembly 2 is provided on the top of the support base 10, and the hinge assembly 2 includes a hinge seat 21 movably supported by one of the aluminum support bars. A longitudinal guide bar 3 is installed at the bottom of the support frame 1, and the support base 10 is provided with a longitudinal guide sleeve 30 for guiding the longitudinal guide bar 3 to move; the angle of the support frame 1 can be adjusted by the hinge assembly 2. During adjustment, the longitudinal guide bar 3 installed on the support frame 1 can move longitudinally along the longitudinal guide sleeve 30 to change the angle of the support frame 1, thereby adjusting the angle of the screen.

[0034] Specifically, there are four aluminum support bars, which are divided into two long aluminum profiles 11 of the same length and two short aluminum profiles 12 of the same length. The two long aluminum profiles 11 of the same length are parallel to each other, and the two short aluminum profiles 12 of the same length are parallel to each other. The long aluminum profile 11 and the short aluminum profile 12 are vertically spliced. The support frame 1 after vertical splicing has better structural stability, and the support stability of the screen can be further improved.

[0035] Preferably, the long aluminum profile 11 and the short aluminum profile 12 are vertically spliced ​​by welding, which can further increase the structural stability.

[0036] The hinge assembly 2 also includes a movable seat 22 installed at the bottom of one of the long aluminum profiles 11, a protrusion block 24 is installed at the bottom of the movable seat 22, and the hinge seat 21 is formed with a concave hinge groove 23. The protrusion block 24 can rotate in the hinge groove 23. By swinging the support frame 1, the movable seat 22 installed at the bottom of one of the long aluminum profiles 11 can rotate in the hinge groove 23 through the protrusion block 24, thereby realizing the angle adjustment of the support frame 1.

[0037] Preferably, the hinge groove 23 is installed with a hinge shaft 25, and the protrusion block 24 is formed with a movable hole 26 coaxially matched with the hinge shaft 25, so that the protrusion block 24 can swing around the hinge shaft 25; through the rotational cooperation between the hinge shaft 25 and the movable hole 26, the protrusion block 24 can swing around the hinge shaft 25, and the stability is further improved when adjusting the angle.

[0038] Preferably, the longitudinal guide bar 3 is installed with a sliding seat 31, and the sliding seat 31 is installed with a transverse sliding block 32, wherein one of the short aluminum profiles 12 is laterally formed with a transverse sliding groove 33 for the transverse sliding block 32 to slide laterally, and when the angle of the support frame 1 changes, the longitudinal guide bar 3 will slide along the longitudinal guide sleeve 30 accordingly, and since the support frame 1 moves in an arc trajectory when swinging, the position of the transverse sliding block 32 located on the longitudinal guide bar 3 will change, and the transverse sliding groove 33 laterally formed on the short aluminum profile 12 can be used for the transverse sliding block 32 to slide laterally, thereby ensuring that the longitudinal guide bar 3 remains connected to the support frame 1 when moving in the vertical direction.

[0039] Preferably, the sliding seat 31 is installed with a connecting bolt 34, the transverse sliding block 32 is formed with a connecting hole 35 connected to the connecting bolt 34, and the transverse sliding block 32 is formed with a sliding inclined surface 36 that slides with the transverse sliding groove 33, and the sliding inclined surface 36 can improve the sliding stability of the transverse sliding block 32.

[0040] The side wall of the longitudinal guide strip 3 is longitudinally formed with a longitudinal sliding groove 27 along the length direction, and the longitudinal guide sleeve 30 is installed with a longitudinal guide block 37 that slides with the longitudinal sliding groove 27, and the longitudinal guide block 37 is installed with a friction bolt 38, and the friction bolt 38 is installed with a friction block 39 that frictionally cooperates with the groove wall of the longitudinal sliding groove 27. When the angle of the support frame 1 reaches a preset angle, the friction bolt 38 is rotated to make the friction block 39 frictionally cooperate with the longitudinal sliding groove 27. At this time, the longitudinal guide strip 3 can be prevented from moving, and the support for the support frame 1 is maintained.

[0041] In addition, since the screen is relatively large, the above-mentioned support can only support the area near the edge of the screen, and the support stability needs to be further improved. For this purpose, the long aluminum profile 11 is slidably installed with a second support member for supporting the screen. The second support member includes a side sliding groove 17 formed along the length direction of the side wall of the long aluminum profile 11. The side sliding groove 17 is slidably installed with a side sliding block 18. The side sliding block 18 is connected to a support plate 19 that fits the back of the screen. The support plate 19 can support the middle area of ​​the back of the screen, further increase the support area, and further improve its support stability.

[0042] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.

[0043] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
