Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Example 1:

[0021] Please see Figure 1 As shown, this utility model provides an LED display positioning fixture, including a left clamping frame 1 and a right clamping frame 2. Side shielding frames 10 are installed on the outer ends of the top of both the left clamping frame 1 and the right clamping frame 2. A connecting frame 5 is fixedly installed at the bottom of the left clamping frame 1. An adjustment groove 6 is laterally opened in the middle of the connecting frame 5. A locking slider 7 is slidably installed at the bottom of the adjustment groove 6. A first adjustment knob 8 is threadedly installed at the bottom of the locking slider 7. Positioning connecting plates 9 are bolted to both sides of the bottom of the left clamping frame 1 and the right clamping frame 2. A support frame 11 is fixedly installed at the outer end of the bottom of the connecting frame 5. A support base 12 is fixedly installed at the bottom of the support frame 11. A telescopic column is snapped onto the bottom of the support base 12, and a support sleeve 13 is sleeved on the lower end of the telescopic column. A second adjustment knob 14 is threaded through the right side of the support sleeve 13. The locking end of the second adjustment knob 14 is tightly connected to the surface of the telescopic column.

[0022] This technical solution, through the combination of adjusting groove 6, locking slider 7 and first adjusting knob 8, allows for flexible adjustment of the distance between left clamping frame 1 and right clamping frame 2, adapting to LED displays of different sizes, greatly improving the versatility of the fixture, meeting diverse production needs. The side shielding frame 10 can limit the lateral movement of the display screen, and together with the top clamping plate 17, it can effectively prevent the display screen from shifting laterally during processing, ensuring positioning accuracy and improving product processing quality. At the same time, the support frame 11, support base 12, telescopic column and support sleeve 13 set at the bottom of the connecting frame 5, together with the second adjusting knob 14, not only provide stable support for the fixture, but also allow for height fine adjustment according to the actual use scenario, ensuring that the fixture remains stable under different working conditions, enhancing the applicability and stability of the fixture.

[0023] Example 2:

[0024] Based on Embodiment 1, this utility model is as follows: Figure 3 As shown, the bottom sides of the left clamping frame 1 are fixedly installed with limiting horizontal plates 3. The right end of the limiting horizontal plate 3 extends to the bottom of the right clamping frame 2 and is slidably connected to the limiting seat 4. The top of the limiting seat 4 is connected to the bottom of the right clamping frame 2, and the locking end of the first adjusting knob 8 is fastened to the bottom of the limiting seat 4.

[0025] Adopting such Figure 1 The technical solution shown features a sliding engagement between the limiting horizontal plate 3 and the limiting seat 4, allowing the two clamping frames to move only in a straight line in the horizontal direction during adjustment. This avoids the possible offset or wobbling that can occur with traditional sliding structures, ensuring that the clamping center is always aligned and significantly improving positioning accuracy. The first adjustment knob 8 acts directly on the bottom of the limiting seat 4, allowing the operator to lock or release the clamp with one hand by rotating the knob, without the need for additional tools. This greatly shortens adjustment time and improves production efficiency. Since the limiting horizontal plate 3 and the limiting seat 4 are a continuous sliding structure, the clamping distance can be infinitely adjusted. Compared with the traditional hole positioning method, this method can more accurately adapt to displays of different sizes, reducing the cost of fixture replacement due to specification differences.

[0026] Secondly, in the technical solution, a base 15 is fixedly installed at the bottom of the support sleeve 13, and a limiting block is fixedly installed on the outside of the telescopic column inside the support sleeve 13. The outside of the limiting block is in close contact with the inside of the support sleeve 13 and is slidably connected. A screw 16 is installed through the top of the side shield 10, and a pressure plate 17 is rotatably installed at the lower end of the screw 16. A rubber pad is glued to the bottom of the pressure plate 17. In addition, the outside of the pressure plate 17 is in sliding contact with the inner wall of the side shield 10.

[0027] Its adoption is as follows Figure 1The technical solution shown has a limiting block on the outside of the telescopic column that slides in close contact with the inside of the support sleeve 13, ensuring that the telescopic column will not detach from the support sleeve 13 when adjusting the height, thus ensuring the normal operation of the height adjustment function. At the same time, the limiting block can guide the telescopic column, making the height adjustment process smoother and more precise. By rotating the screw 16, the downward pressure of the clamping plate 17 can be flexibly controlled to achieve precise clamping of LED displays of different thicknesses. The clamping force can be adjusted as needed to meet diverse positioning requirements. The rubber pad bonded to the bottom of the clamping plate 17 has good elasticity and anti-slip properties, which can increase the friction with the surface of the display screen to prevent the display screen from sliding, and also avoid scratches, indentations and other damage to the surface of the display screen during the clamping process, ensuring that the appearance and performance of the display screen are not affected.

[0028] Example 3:

[0029] This utility model is shown in Figure 1. Figure 4 As shown, a sliding rod is fixedly installed at the bottom of the connecting frame 5 and outside the adjusting groove 6. The end of the locking slider 7 is engaged with the surface of the sliding rod and is installed laterally. The left clamping frame 1 and the right clamping frame 2 are symmetrically arranged, and the internal placement of the left clamping frame 1 and the right clamping frame 2 are both set on the same horizontal plane.

[0030] Using the above technical solution, the slide bar and the adjusting groove 6 form a double guiding structure, so that the locking slider 7 can only move in a straight line in the horizontal direction during the sliding process, avoiding the lateral displacement that may occur in the traditional single track structure, and ensuring the synchronization of the left and right clamping frames.

[0031] The working principle of this utility model is as follows: First, according to the width of the LED display screen, loosen the first adjustment knob 8 so that the locking slider 7 and the connecting frame 5 are in an active state. Then, move the right clamping frame 2 laterally and drive the limiting seat 4 to move on the surface of the limiting horizontal plate 3 so that the right side shielding frame 10 is locked at the end of the display screen and clamped. After the adjustment is completed, tighten the first adjustment knob 8 to fix it. Then, rotate the upper screw 16 to drive the pressing plate 17 to move down and use the bottom rubber pad to press the display screen longitudinally. At the same time, the side shielding frame 10 restricts the lateral movement of the display screen to achieve precise positioning.

[0032] When height adjustment is required, loosen the second adjustment knob 14, slide the telescopic column up and down to adjust the height of the support base 12, and tighten the second adjustment knob 14 after the fixture reaches the appropriate working height.
