[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The LED display screen with an adjustable bracket is provided with a support beam, a base and an elastic limiter. When the height of the display screen needs to be adjusted, the user only needs to easily pull the handle. The movement of the handle indirectly drives the support beam to slide inside the base. During the sliding process, after the elastic limiter is restrained by an external force, the spring exerts its elastic deformation, and the limit block slides inside the movable groove. When the height adjustment is completed, the spring recovers its deformation and squeezes the limit block back into the limit groove, thereby realizing self-locking between the support beam and the base. When adjusting the height, the height adjustment of the display screen can be completed by pulling the handle. The operation process is extremely convenient and effortless. The self-locking performance of the elastic limiter can also ensure that the height of the display screen is firmly locked after the adjustment is completed.

[0015] 2. Through the setting of the locking rod, when the display screen is adjusted and self-locking is achieved, the knob is manually rotated, and the knob drives the locking rod to rotate synchronously. By adjusting the rotation direction of the locking block, the locking block can be abutted between the two sets of limit blocks to achieve secondary locking of the limit blocks. In this way, the influence of the display screen's own weight and the situation in which the height cannot be fixed due to the change of the elastic limit piece on its own can be avoided. Through the secondary fixation of the locking rod, the relative position between the support beam and the base will remain stable, ensuring that the height adjustment of the display screen is in a reliable locked state.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 As shown, the utility model provides an implementation mode: an LED display screen with an adjustable bracket, comprising a display screen 1, a support beam 3, an elastic limiter 5 and a locking rod 6, a mounting plate 2 is bolted to the back side of the display screen 1, a support beam 3 is welded to the other side of the mounting plate 2 through a connecting block, a plurality of groups of elastic limiters 5 are movably mounted on the lower end of the inner part of the support beam 3, a locking rod 6 for changing the position of the elastic limiter 5 is rotatably mounted inside the support beam 3, a base 7 is slidably mounted on the outer side of the support beam 3, and a placement table 8 is welded to the lower end of the base 7.

[0024] Furthermore, the support beam 3 is composed of a hollow column 31 and a limit column 32. The hollow column 31 is welded to the other side of the mounting plate 2 through a connecting block. The limit column 32 is welded to the lower end of the hollow column 31, and the hollow column 31 is connected to the inside of the limit column 32 through penetration. The locking rod 6 is installed through the inside of the hollow column 31 and the limit column 32.

[0025] Furthermore, a connecting seat 311 is welded to the upper end of the hollow column 31, and a hole is opened inside the connecting seat 311, and the hole passes through the interior of the hollow column 31. A bearing 312 is fixedly installed on the inner side of the connecting seat 311, and the locking rod 6 is rotatably installed inside the hollow column 31 through the bearing 312. When the knob 61 is manually rotated, the locking rod 6 will be driven to rotate synchronously inside the hollow column 31.

[0026] Furthermore, guide blocks 321 are welded on both the front and rear sides of the limit column 32, and guide grooves 71 for the guide blocks 321 to slide are provided on both the front and rear sides of the base 7. When the support beam 3 slides inside the limit column 32, the guide blocks 321 on both sides of the support beam 3 slide in the guide grooves 71. Multiple groups of movable grooves 322 are evenly and equidistantly provided on the left and right sides of the limit column 32. The movable grooves 322 are used to limit the position of the limit block 51. A sliding groove 323 is provided inside the limit column 32 and on the inner side of the two groups of movable grooves 322.

[0027] Furthermore, two groups of support beams 3 are installed, and connecting rods 4 are welded to the inner upper ends of the two groups of support beams 3. Handles 41 are screwed to the upper ends of the connecting rods 4. When the overall height of the display screen 1 needs to be adjusted, the display screen 1 can be moved by pulling the handle 41.

[0028] Furthermore, the elastic limit member 5 includes a limit block 51, a connecting pin 52 and a spring 53. The limit block 51 is movably installed inside the movable groove 322. The position of the limit block 51 corresponds to that of the movable groove 322. A plurality of limit grooves 72 for limiting the movement of the limit block 51 are evenly spaced on both sides of the inner side of the base 7. The inner sides of the two groups of limit blocks 51 are clamped by the connecting pin 52 to hold the spring 53. The elastic deformation of the spring 53 can squeeze the limit block 51 inside the limit groove 72. When the support beam 3 is moved by an external force, the elastic deformation of the inner side of the limit block 51 is The spring 53 will be elastically compressed, and the limit block 51 will slide out of the limit groove 72. After the adjustment is completed, the spring 53 restores its deformation and squeezes the limit block 51 into the limit groove 72 to achieve self-locking between the support beam 3 and the base 7. Slide blocks 54 sliding in the slide groove 323 are welded on both sides of the limit block 51. When the limit block 51 slides in the movable groove 322, the slide blocks 54 on both sides of the limit block 51 slide in the slide groove 323. The slide groove 323 provides a sliding path for the slide block 54 to avoid the slide block 54 from running off.

[0029] Furthermore, a knob 61 is welded on the upper end of the locking rod 6, and a marker rod 611 is welded on the lower end of the knob 61. The direction of the marker rod 611 is parallel to the long side of the locking block 62, so that the operator can judge the internal state of the locking block 62 according to the direction of the marker rod 611 when rotating the knob 61. The locking block 62 is welded on the outer side of the area of ​​the locking rod 6 located inside the limiting column 32. In the adjustment state, the long side of the locking block 62 abuts against the front and rear sides of the limiting column 32, and in the non-adjustment state, the long side of the locking block 62 abuts against the inner sides of the two groups of limiting blocks 51. The long side of the locking block 62 can squeeze the limiting blocks 51 on both sides, which can ensure the stability of the position of the display screen 1, and the locking block 62 is installed in the middle of the upper and lower groups of springs 53 in the single group of elastic limiting components 5. When the locking block 62 rotates, the position of its spring 53 will not affect the rotation of the locking block 62.

[0030] Working principle: First, move the LED display screen with an adjustable bracket to the working position. In the first step, when using the display screen 1, the placement table 8 can be placed on a relatively flat ground. In the second step, the height of the display screen 1 can be adjusted according to the use requirements. First, manually rotate the knob 61, and the knob 61 drives the locking rod 6 to rotate, and rotate the direction of the benchmark 611 to the vertical state of the display screen 1. At this time, the inner side of the limit block 51 loses the restriction of the locking block 62. In the third step, manually pull the handle 41 to drive the support beam 3 to move through the connecting rod 4. When the support beam 3 is restrained by external force, the limit block 51 will automatically retract into the movable groove 322 and disengage from the limit groove 72. At this time, the support There is no limit assembly between the beam 3 and the base 7, so the support beam 3 can drive the display screen 1 to slide through the mounting plate 2. In the fourth step, after the adjustment is completed, the limit block 51 is elastically squeezed by the spring 53 and squeezed into the limit groove 72, thereby realizing the self-locking of the relative position of the support beam 3 and the base 7. In the fifth step, in order to further ensure that the position of the display screen 1 is fixed, the knob 61 is manually rotated to make the benchmark 611 and the display screen 1 parallel. At this time, the long side of the locking block 62 on the outside of the locking rod 6 will abut against the inner side of the limit block 51. Through the auxiliary fixation of fixed locking, the position of the display screen 1 is made more stable, thereby completing the use process of the LED display screen with an adjustable bracket.
