Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] Example 1

[0023] The problem to be solved is that existing monitor stand angle adjustment methods are cumbersome and do not make it easy for testers to understand the value of the monitor's adjustment angle, thus affecting the staff's ability to adjust different angles to test the monitor.

[0024] The solution is as follows: An angle-adjustable display screen test bracket includes a device body 1. The device body 1 includes a first rotating mounting base 2, a second rotating mounting base 3, a display screen bracket 4, and a rear connecting block 5. The first rotating mounting base 2 and the second rotating mounting base 3 are distributed horizontally at equal intervals. The display screen bracket 4 is installed at the front end between the first rotating mounting base 2 and the second rotating mounting base 3. The rear connecting block 5 is fixed to the rear end of the front end between the first rotating mounting base 2 and the second rotating mounting base 3 by screws. The display screen bracket 4 has a U-shaped structure and includes a horizontal block 17, a first vertical block 18, and a second vertical block 19. The vertical block 19, the first vertical block 18, the second vertical block 19 and the horizontal block 17 are smoothly transitioned and integrally formed. The first vertical block 18 and the second vertical block 19 are located at the top left end and top right end of the horizontal block 17, respectively. The top of the first rotating mounting base 2 and the second rotating mounting base 3 are both fixed with electronic digital display angle rulers 6 by screws. The measuring end of the electronic digital display angle ruler 6 is provided with a connecting hole 7. The connecting hole 7 is fixed with a connecting rod 8. The connecting rod 8 has a Z-shaped structure. The two sets of electronic digital display angle rulers 6 are connected to the outside of the first vertical block 18 and the second vertical block 19, respectively, through the connecting rod 8.

[0025] Analysis of the above: The first rotating mounting base 2 and the second rotating mounting base 3 provide the mounting foundation for the display screen bracket 4, and the connecting block 5 enhances the stability of the connection between the two. The first vertical block 18, the second vertical block 19, and the horizontal block 17 of the display screen bracket 4 are integrally formed, ensuring structural stability. When the display screen bracket 4 rotates, the measuring end of the electronic digital display angle ruler 6 rotates through the Z-shaped connecting rod 8. The electronic digital display angle ruler 6 (labeled 6) can accurately measure and display the rotation angle of the first vertical block 18 and the second vertical block 19 in real time, thereby reflecting the angle change of the display screen. When it is necessary to adjust the angle of the display screen, the display screen bracket 4 can be rotated directly, and the electronic digital display angle ruler 6 will display the angle value simultaneously, which facilitates precise control and adjustment of the angle. The concave structure and integral molding design of the display screen bracket 4 improve the overall structural stability and load-bearing capacity. The setting of the electronic digital display angle ruler 6 realizes the digital and precise measurement of the angle, which is more intuitive and accurate than the traditional angle measurement method. The Z-shaped connecting rod 8 can flexibly transmit rotation information, ensuring the accuracy of angle measurement.

[0026] Example 2:

[0027] Please see Figure 1-3 This utility model provides a technical solution based on Embodiment 1: the first rotating mounting base 2 and the second rotating mounting base 3 are both rectangular in shape. The bottom of the first rotating mounting base 2 and the second rotating mounting base 3 is provided with a rubber bonding pad 15. The top front end of the first rotating mounting base 2 and the second rotating mounting base 3 is provided with a damping bearing seat 9. The top of the damping bearing seat 9 is provided with an arc head 11. The surface of the damping bearing seat 9 is provided with a bearing mounting hole 10. The sides of the first rotating mounting base 2 and the second rotating mounting base 3 are provided with a reinforcing groove 13. The reinforcing groove 13 is trapezoidal in shape. The reinforcing groove 13 is provided with a reinforcing block 14. The reinforcing block 14 is triangular in shape. The top of the first rotating mounting base 2 and the second rotating mounting base 3 is provided with a plurality of sets of mounting holes 12. The sides of the first rotating mounting base 2 and the second rotating mounting base 3 are provided with a set of assembly holes 16.

[0028] Analysis of the above: The rectangular structures of the first rotating mounting base 2 and the second rotating mounting base 3 provide stable support. The rubber mat 15 at the bottom increases friction with the placement surface, preventing the bracket from sliding. The bearing in the damping bearing seat 9 is installed through the bearing mounting hole 10. The rotating bearing 20 of the display bracket 4 cooperates with the bearing mounting hole 10. During rotation, the damping bearing seat 9 provides appropriate resistance, making the rotation smoother and avoiding sudden changes in angle. The triangular reinforcing block 14 in the reinforcing groove 13 enhances the structural strength of the mounting base and prevents deformation. The ruler fixing hole 12 is used to fix the electronic digital display angle ruler 6, and the assembly hole 16 facilitates connection with the rear connecting block 5. The combination of the trapezoidal reinforcing groove 13 and the triangular reinforcing block 14 greatly enhances the structural strength and deformation resistance of the mounting base while reducing weight.

[0029] Example 3:

[0030] Please see Figure 1-3 Based on Embodiment 1, this utility model provides a technical solution: the first vertical block 18 and the second vertical block 19 are provided with weight-reducing slots 22 inside, and the surfaces of the first vertical block 18 and the second vertical block 19 are provided with a plurality of groups of heat dissipation holes 23 distributed in a row at equal intervals. The heat dissipation holes 23 are rectangular in shape. The sides of the first vertical block 18 and the second vertical block 19 are respectively provided with rod holes 26 and a set of display screen locking holes 24. The front left and right sides of the first vertical block 18 and the second vertical block 19 are provided with a plurality of groups of side support blocks 25.

[0031] Analysis of the above: The weight-reducing slots 22 inside the first vertical block 18 and the second vertical block 19 reduce the overall weight without affecting the structural strength. The ventilation holes 23 allow airflow, helping the display screen mounted on the bracket to dissipate heat and preventing overheating from affecting test results. The rod holes 26 are used to connect the connecting rod 8, the display screen locking holes 24 are used to fix the display screen to the bracket, and the side support blocks 25 provide lateral support for the display screen, enhancing the fixing effect. When installing the display screen, it is fixed with screws or other screws through the display screen locking holes 24. The side support blocks 25 can be adapted to fit the display screen size. When testing a display screen that generates significant heat, the ventilation holes 23 allow for natural ventilation. If higher heat dissipation is required, external cooling equipment can be used to enhance the heat dissipation effect through the ventilation holes. When it is necessary to reduce the overall weight of the bracket, the weight-reducing slots 22 already serve their purpose, requiring no additional operation.

[0032] Example 4:

[0033] Please see Figure 1-3Based on Embodiment 1, this utility model provides a technical solution: both the left and right ends of the transverse block 17 are provided with rotating bearings 20, the outer end of the rotating bearing 20 is provided with several sets of locking threads 21, the rotating bearing 20 passes through the bearing mounting hole 10 and is fixed by locking nuts and several sets of washers.

[0034] Analysis of the above: The rotating bearings 20 at both ends of the horizontal block 17 pass through the bearing mounting holes 10 of the first rotating mounting base 2 and the second rotating mounting base 3, and are fixed by locking threads 21, locking nuts, and washers, allowing the display screen bracket 4 to rotate flexibly around the rotating bearings 20 to achieve angle adjustment. The rear connecting block 5 is connected to the first rotating mounting base 2 and the second rotating mounting base 3 through the assembly hole 16, enhancing the overall structural stability of the device. The structural groove 27 reduces the weight of the rear connecting block 5 while enhancing its structural strength. The fixing hole 28 is used to fix the entire device to other platforms, and the rubber bonding pad 15 at the bottom also serves as an anti-slip device. When adjusting the display screen angle, the display screen bracket 4 is rotated, and the rotating bearings 20 allow for smooth rotation. After adjusting to the desired angle, the locking threads 21 and locking nuts are used to tighten and fix it.

[0035] Example 5:

[0036] Please see Figure 1-3 The present invention provides a technical solution based on embodiment one: the rear connecting block 5 is also provided with assembly holes 16 at both ends, the rear connecting block 5 is provided with fixing holes 28 at the four corners of the top, the rear connecting block 5 is provided with several sets of structural grooves 27 at the top, the structural grooves 27 are in a cross shape, and the bottom of the rear connecting block 5 is also provided with rubber bonding pads 15.

[0037] Analysis of the above content: When it is necessary to fix the entire device on the test platform, it can be fixed through the fixing hole 28 of the rear connecting block 5. To enhance the overall stability of the device, check whether the connection between the rear connecting block 5 and the rotating mounting base is firm.
