Description

Technical Field

[0001] The utility model relates to the technical field of protection of a main control board of a digital broadcasting power amplifier device, in particular to an adjustable protection device. Background Art

[0002] Digital broadcasting refers to the encoding, modulation, transmission and other processing of digitized audio signals, video signals, and various data signals in a digital state. At the same time, digital broadcasting is also different from the traditional AM and FM broadcasting technology. It transmits digital signals through ground transmission stations to achieve the purpose of broadcasting and data information transmission.

[0003] The main control board of the existing digital broadcasting power amplifier device is generally directly fixed and installed inside the protective shell, which has the protective effects of dust and touch protection. However, in the existing installation of the main control board, the four corners of the main control board need to be fixedly connected by fixing parts. The installation process is relatively cumbersome and time-consuming, and it is not convenient to disassemble the main control board for maintenance. Moreover, the position of the main control board of the existing digital broadcasting power amplifier device is relatively fixed after being installed, which is not convenient for adjustment. The bottom of the main control board after installation is in contact with the installation position, which makes the air permeability of the main control board poor, affecting the heat dissipation. Moreover, after the main control board installed at the bottom end of the protective shell is disassembled, the maintenance personnel need to put their hands into the protective shell for disassembly. After the hands are put into the protective shell, the field of vision is blocked, so it is very inconvenient to disassemble the main control board. For this reason, we propose an adjustable protective device. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0021] See also Figure 1-4 The utility model provides a technical solution: an adjustable protective device, including a protective box 1, a mounting cover 2 is installed on the top of the protective box 1, a support adjustment mechanism 3 is arranged at the bottom of the inner wall of the protective box 1, and a clamping mechanism 4 is symmetrically arranged on the top of the support adjustment mechanism 3, and a main control board 5 is arranged between the two clamping mechanisms 4. Through the setting of the support adjustment mechanism 3, it not only plays a supporting role, but also can adjust the height of the support plate 8.

[0022] It should be noted that when the utility model is installing the main control board 5, the installation cover 2 is opened, and then the rotating block 12 is rotated to rotate the bidirectional screw 6. The two sliding blocks 7 are connected to the threads at both ends of the bidirectional screw 6, so that the two sliding blocks 7 move away from each other, and the support plate 8 is raised under the support of the adjusting rod 10. When the support plate 8 is raised to the top of the inside of the protection box 1, the two clamping mechanisms 4 are located outside the protection box 1. At this time, the adjusting screw 17 is loosened, and the distance between the two clamping plates 13 is adjusted to adapt to the size of the main control board 5. After adjustment, the adjusting screw 17 is tightened again to make the fixing plate 16 press against the top of the inner wall of the slide groove 15, so that the position of the clamping plate 13 is fixed, and the slide bar 20 is pulled up to move the two ends of the main control board 5. The two ends are respectively clamped between the positioning pressure plate 19 and the placement plate 18 on the two holding plates 13, so that the position of the main control board 5 is fixed, thereby realizing the installation of the main control board 5. After the installation is completed, the rotating block 12 is rotated in the opposite direction to make the two sliding blocks 7 approach each other, and the supporting plate 8 is moved down under the action of the adjusting rod 10, so that the main control board 5 is placed inside the protective box 1, and the setting of the connecting groove 11 makes the bottom and top middle areas of the main control board 5 in a suspended state, which increases the air permeability of the main control board 5 and is more conducive to the heat dissipation of the main control board 5 (the protective box 1 is also provided with relevant devices for the heat dissipation of the main control board 5). When the main control board 5 needs to be repaired, the supporting plate 8 is also controlled to rise, and then the sliding rod 20 is pulled up to directly remove the main control board 5.

[0023] The supporting and adjusting mechanism 3 comprises a bidirectional screw 6, a sliding block 7 and a supporting plate 8. The bottom ends of the two inner walls of the protective box 1 corresponding to the two inner walls are rotatably connected with the bidirectional screw 6 through bearings, and the ends of the bidirectional screw 6 pass through the protective box 1 and are fixedly connected with a rotating block 12. The two ends of the bidirectional screw 6 are symmetrically threadedly connected with the sliding blocks 7, and the top of the sliding block 7 is rotatably connected with an adjusting rod 10. A supporting plate 8 is slidably connected in the protective box 1, and both ends of the bottom of the supporting plate 8 are fixedly connected with mounting blocks 9. The ends of the two adjusting rods 10 are rotatably connected with the two mounting blocks 9 respectively. Through the setting of the supporting and adjusting mechanism 3, not only a supporting function is played, but also the height of the supporting plate 8 can be adjusted. When installing or removing the main control board 5, the support plate 8 can be controlled to be located at the top position inside the protective box 1, so that the holding mechanism 4 is located outside the protective box 1. During the installation and removal of the main control board 5, there is no need to put your hands into the interior of the protective box 1, and there is no obstruction of the line of sight, which greatly facilitates the installation and removal of the main control board 5.

[0024] It should be noted that, when adjusting, the rotating block 12 is rotated to rotate the bidirectional screw 6, and the two sliding blocks 7 are threadedly connected to the two ends of the bidirectional screw 6 to move away from each other. Under the support of the adjusting rod 10, the support plate 8 is raised, thereby realizing the height adjustment of the main control board 5.

[0025] The bottom ends of the two inner walls of the protective box 1 are symmetrically fixed with positioning rods 23, and horizontal positioning holes are symmetrically opened on both sides of the sliding block 7. The positioning rods 23 are slidably connected in the positioning holes, and the sliding block 7 is slidably connected to the outside of the positioning rods 23 to limit the sliding block 7 and ensure the stable sliding of the sliding block 7 in the horizontal direction.

[0026] The holding mechanism 4 includes a holding plate 13, and a vertically reverse connecting groove 11 is opened at the top center of the support plate 8. The setting of the connecting groove 11 makes the bottom and top middle areas of the main control board 5 suspended, which increases the air permeability of the main control board 5 and is more conducive to the heat dissipation of the main control board 5 (related devices for heat dissipation of the main control board 5 are also provided on the protective box 1).

[0027] A holding plate 13 is symmetrically arranged on the top of the support plate 8, and a convex plate 14 is integrally connected to the bottom end of the holding plate 13. The convex plate 14 is slidably connected to the top of the support plate 8. A vertical sliding hole is opened on the top of the holding plate 13, and a sliding rod 20 is slidably connected in the sliding hole. A positioning pressure plate 19 is fixedly connected to the bottom of the sliding rod 20. A spring 21 is sleeved between the positioning pressure plate 19 and the holding plate 13 on the outer side of the sliding rod 20. A placement plate 18 is arranged on the bottom end of the holding plate 13 away from the convex plate 14. The end of the main control board 5 is located between the positioning pressure plate 19 and the placement plate 18, which is convenient for the installation of the main control board 5. By pulling up the sliding rod 20, the two ends of the main control board 5 are respectively clamped between the positioning pressure plates 19 and the placement plates 18 on the two holding plates 13, so that the position of the main control board 5 is fixed, thereby realizing the installation of the main control board 5.

[0028] A slide groove 15 is symmetrically provided in the support plate 8, a limit groove 22 is provided on the top of the support plate 8, and the limit groove 22 is communicated with the inside of the slide groove 15, an adjusting screw 17 is provided on the top of the convex plate 14, and the bottom end of the adjusting screw 17 is slidably connected in the limit groove 22, one end of the adjusting screw 17 located in the slide groove 15 is threadedly connected to the fixing plate 16, and the corresponding two inner walls of the fixing plate 16 are in contact with the corresponding two inner walls of the slide groove 15.

[0029] It should be noted that when the horizontal sliding adjustment of the clamping plate 13 is required, the adjusting screw 17 is rotated, and the fixed plate 16 is slidably set in the slide groove 15 through cooperation. The threaded connection between the fixed plate 16 and the adjusting screw 17 causes the fixed plate 16 to move downward, and the fixed plate 16 is out of contact with the top of the inner wall of the slide groove 15, so that the convex plate 14 can slide on the support plate 8, thereby realizing the adjustment of the position of the tooth plate 13. After the adjustment is completed, tighten the adjusting bolt 17 so that the fixed plate 16 is fixed tightly to the top of the inner wall of the slide groove 15 again, so that the position of the convex plate 14 is fixed.

[0030] The thickness of the fixing plate 16 is smaller than the height of the sliding groove 15 , so that the fixing plate 16 can slide horizontally and move vertically inside the sliding groove 15 .
