[0006] As a further improvement to the above scheme, two limit blocks are provided, and the two limit blocks are symmetrically arranged around the center of the combined rod. Two limit blocks are provided, and the two limit blocks are symmetrically arranged around the center of the limit seat.
[0007] As a further improvement to the above solution, two limiting grooves are provided, and the two limiting grooves are symmetrically arranged around the center of the combined rod. Two combined connecting rods are provided, and the two combined connecting rods are symmetrically arranged around the center of the combined rod.
[0008] The above technical solution involves installing the combined connecting rod into the limiting groove opened in the combined rod, then inserting the limiting rod into the combined connecting rod to connect the combined rod and the combined connecting rod. Then, the T-shaped slider is installed into the T-shaped sliding groove opened in the combined connecting rod, thereby installing the LCD screen onto the front of the combined connecting rod via the T-shaped slider.
[0009] As a further improvement to the above solution, a clearance groove is provided on the left side of the limiting block, a spring is fixedly connected to the inner wall of the limiting block, the left side of the spring is fixedly connected to the right side of the adjusting rod, a rotating rod is rotatably connected to the inner wall of the limiting block, and the outer wall of the rotating rod contacts the inner wall of the clearance groove.
[0010] As a further improvement to the above solution, the rotating rod is fixedly connected to the upper and lower limit blocks on the front side, the outer wall of the adjusting rod is fixedly connected to the outer wall of the upper and lower limit blocks, the limit block one has a limit groove two on the top right side, and the limit block one has a left and right limit blocks fixedly connected to the top left side.
[0011] As a further improvement to the above solution, the inner wall of the limiting groove two is provided with left and right limiting blocks two. The end of the left and right limiting blocks two away from the limiting groove two is fixedly connected to the bottom right side of the limiting block two. A limiting groove three is opened on the bottom left side of the limiting block two.

The outer wall of the rotating rod two is rotatably connected to the inner wall of the limiting block two.
[0013] Through the above technical solution, the bottom of the limiting block 2 is aligned with the top of the limiting block 1, and then the left and right limiting blocks 2 on the bottom right side of the limiting block 2 are inserted into the limiting groove 2 on the top right side of the limiting block 1, thereby limiting the left and right sides of the limiting block 1 and the limiting block 2. When the limiting block 2 slides down, the upper and lower limiting blocks 2 inside the limiting block 2 rotate around the rotating rod 2, causing the adjusting rod 2 to slide along the inside of the clearance groove 2. At the same time, the upper and lower limiting blocks 2 press down on the upper and lower limiting blocks, causing the upper and lower limiting blocks to rotate around the rotating rod 2.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention connects the combined rod and the combined rod by installing the combined connecting rod into the limiting groove, and then inserting the limiting rod into the combined connecting rod. A T-shaped slider is then installed into the T-shaped sliding groove of the combined connecting rod, allowing the LCD screen to be mounted on the front of the combined connecting rod via the T-shaped slider. Simultaneously, a buffer rubber is fixedly connected to the outer wall of the LCD screen to cushion the impact between the LCD screens, preventing damage caused by collisions due to vibration. This combination connection method is simple and has a wide range of applications.
[0016] This invention aligns the bottom of the second limiting block with the top of the first limiting block, and then inserts the left and right limiting blocks of the second limiting block (bottom right side) into the limiting groove (top right side) of the first limiting block, thereby limiting the left and right sides of the first and second limiting blocks. As the second limiting block slides downwards, the upper and lower limiting blocks inside it rotate around the rotating rod, causing the adjusting rod to slide along the clearance groove. Simultaneously, the upper and lower limiting blocks press down on the upper and lower limiting blocks, causing them to rotate around the rotating rod, and simultaneously the upper and lower limiting blocks drive the adjusting rod to slide along the clearance groove. The clearance groove slides, and then the left and right limit blocks on the top left of limit block one are engaged in the limit groove three on the bottom left of limit block two. When the top of limit block one and the bottom of limit block two are fully engaged, under the reaction force of the spring and spring two, the spring pulls the adjusting rod, causing the adjusting rod to drive the upper and lower limit blocks to rotate along the rotating rod. At the same time, spring two pulls the adjusting rod two to rotate around the rotating rod two, thereby causing the upper and lower limit blocks and upper and lower limit blocks two to engage limit block one and limit block two, so that limit block one and limit block two cannot be separated without the adjustment rod being manually moved.

[0031] There are two limiting grooves 7, which are symmetrically arranged around the center of the combined rod 6. There are two combined connecting rods 9, which are symmetrically arranged around the center of the combined rod 6.
[0032] The left side of the limiting block 3 has an avoidance groove 14. A spring 15 is fixedly connected to the inner wall of the limiting block 3. The left side of the spring 15 is fixedly connected to the right side of the adjusting rod 16. A rotating rod 17 is rotatably connected to the inner wall of the limiting block 3. The outer wall of the rotating rod 17 contacts the inner wall of the avoidance groove 14.
[0033] The rotating rod 17 is fixedly connected to the upper and lower limit blocks 18 on the front. The outer wall of the adjusting rod 16 is fixedly connected to the outer wall of the upper and lower limit blocks 18. The upper right side of the limit block 13 has a limit groove 19.

[0034] The inner wall of the limiting groove 21 is provided with left and right limiting blocks 21.

A rotating rod 25 is fixedly connected to the outer wall of the upper and lower limiting blocks 26. The outer wall of the rotating rod 25 is rotatably connected to the inner wall of the limiting block 24.
[0036] The implementation principle of a splicing LCD display with a combined structure in this application embodiment is as follows: By aligning the bottom of the second limiting block 4 with the top of the first limiting block 3, and then inserting the left and right limiting blocks 21 on the bottom right side of the second limiting block 4 into the limiting groove 19 on the top right side of the first limiting block 3, the left and right sides of the first limiting block 3 and the second limiting block 4 are limited. When the second limiting block 4 slides downward, the upper and lower limiting blocks 26 inside the second limiting block 4 rotate around the rotating rod 25, causing the adjusting rod 24 to slide along the clearance groove 22. At the same time, the upper and lower limiting blocks 26 press down on the upper and lower limiting blocks 18, causing the upper and lower limiting blocks 18 to rotate around the rotating rod 17. Simultaneously, the upper and lower limiting blocks 18 cause the adjusting rod 16 to slide along the clearance groove 14. Then, the left and right limiting blocks 20 on the top left side of the first limiting block 3 are engaged with the bottom left side of the second limiting block 4. Inside the limiting groove 27 on the side, when the top of limiting block 3 and the bottom of limiting block 4 are fully engaged, under the reaction force of spring 15 and spring 23, spring 15 pulls the adjusting rod 16, causing the adjusting rod 16 to drive the upper and lower limiting blocks 18 to rotate along the rotating rod 17. At the same time, spring 23 pulls the adjusting rod 24 to rotate around the rotating rod 25, thereby causing the upper and lower limiting blocks 18 and upper and lower limiting blocks 26 to lock the limiting blocks 3 and 4, preventing the limiting blocks 3 and 4 from separating without manual external force to move the adjusting rod. This allows connecting rod 2 and connecting rod 25 to be connected through limiting blocks 3 and 4. Then, connecting rod 25 drives the combined rod 6 and connecting rod 3 28, allowing the display bracket to be spliced in multiple layers as needed, increasing the product's flexibility and practicality. After the support frame is assembled, the combined connecting rod 9 is... The LCD screen 12 is installed into the limiting groove 7 of the combination rod 6, and then the limiting rod 8 is inserted into the combination connecting rod 9, thereby connecting the combination rod 6 and the combination connecting rod 9. Then, the T-shaped slider 11 is installed into the T-shaped sliding groove 10 of the combination connecting rod 9, thereby installing the LCD screen 12 onto the front of the combination connecting rod 9 through the T-shaped slider 11. At the same time, the outer wall of the LCD screen 12 is fixedly connected with a buffer rubber 13 to provide cushioning between the LCD screens 12, preventing the LCD screens 12 from colliding due to vibration and causing damage. This combination connection method is simple and has a wide range of applications.
