DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figure 1-4 The utility model provides a technical solution: a high-precision and conveniently installed RF DC power supply structure, comprising a structural body 1, an RF DC power supply 7 is arranged inside the structural body 1, and fixing holes 18 are opened on both sides of the upper and lower ends of the structural body 1;

[0026] The structure body 1 further comprises a sliding cavity 2, which is provided on both sides of the upper and lower ends of the interior of the structural body 1, a sliding rod 4 is slidably arranged inside the sliding cavity 2, and one end of the sliding rod 4 extends to the outside of the sliding cavity 2, and L-shaped plates 5 are arranged on both sides of the structural body 1, and the L-shaped plates 5 are connected to one end of the sliding rod 4 located outside the sliding cavity 2;

[0027] It also includes a transmission cavity 8, which is opened at the upper end of the structural main body 1. A threaded rod 9 is rotatably installed at the middle position inside the transmission cavity 8. The external thread of the threaded rod 9 is connected to a lifting plate 10. Both sides of the lower end of the lifting plate 10 are adhered and fixed with connecting blocks 12. A storage groove 19 is opened at the bottom of the transmission cavity 8. One end of the connecting block 12 penetrates and extends to the inside of the storage groove 19, and the connecting block 12 is slidably matched with the storage groove 19.

[0028] When in use, the L-shaped plate 5 is pulled to make the slide bar 4 drive the L-shaped plate 5 to move synchronously. At this time, the reset spring 3 will be stretched, and the RF DC power supply 7 is placed in the front end of the structural main body 1 and the L-shaped plate 5 is released. Under the elastic action of the reset spring 3, the L-shaped plate 5 will move in the direction of the RF DC power supply 7, and the front end of the L-shaped plate 5 will limit the front end of the RF DC power supply 7. At the same time, the L-shaped plate 5 will drive multiple fixing blocks 6 to squeeze one side of the RF DC power supply 7, so that the RF DC power supply 7 can be moved toward the middle position of the structural main body 1, and finally the RF DC power supply 7 can be clamped and fixed in the middle position of the structural main body 1, so that there is no need for manual alignment and installation, and the installation position of the RF DC power supply 7 can be well guaranteed to be centered, thereby improving the installation accuracy.

[0029] See also Figure 4 , a return spring 3 is provided inside the sliding cavity 2, and the sliding rod 4 and one end inside the sliding cavity 2 are connected to the sliding cavity 2 through the return spring 3, and the elastic action of the return spring 3 enables the L-shaped plate 5 to drive the fixing block 6 to limit and fix the RF DC power supply 7;

[0030] See also Figure 1 , Figure 2 and Figure 4 A rotating shaft 14 is disposed at the upper end of the threaded rod 9, and one end of the rotating shaft 14 extends to the outside of the transmission cavity 8. A knob 15 is disposed at one end of the rotating shaft 14 located outside the transmission cavity 8. The knob 15 is disposed to facilitate rotation by the user;

[0031] See also Figure 2 and Figure 4 A protective cover 16 is provided on the outside of the knob 15, and the protective cover 16 is connected to the structural body 1 through a hinge. A magnetic iron sheet 17 is adhered and fixed to one side of the lower end of the protective cover 16 and one side of the upper end of the structural body 1. The provision of the magnetic iron sheet 17 can firmly fix the protective cover 16 on the upper end of the structural body 1;

[0032] See also Figure 2 and Figure 4 A lower pressing plate 13 is disposed inside the storage groove 19, and the lower pressing plate 13 is adhered and fixed to one end of the connecting block 12 located inside the storage groove 19. The storage groove 19 can store the lower pressing plate 13 to avoid affecting the use;

[0033] See also Figure 1 and Figure 3 The inside of the L-shaped plate 5 is bonded and fixed with five equally spaced fixed blocks 6. The equally spaced distribution of the fixed blocks 6 can avoid large-area contact with the RF DC power supply 7, thereby ensuring the heat dissipation effect of the RF DC power supply 7;

[0034] See also Figure 4Guide rods 11 are bonded and fixed on both sides of the transmission cavity 8. The guide rods 11 all penetrate the lifting plate 10, and the guide rods 11 are slidably matched with the lifting plate 10. The guide rods 11 can limit the axial position of the lifting plate 10, so that the rotation of the lifting plate 10 is converted into vertical movement up and down.

[0035] Working principle: When in use, the structural body 1 can be first installed on the wall through the fixing holes 18 at the upper and lower ends thereof, and the L-shaped plate 5 on one side is pulled. The movement of the L-shaped plate 5 will drive the slide bar 4 to slide synchronously inside the slide cavity 2, and the sliding of the slide bar 4 will stretch the reset spring 3. The RF DC power supply 7 is placed in the front end of the structural body 1. After the L-shaped plate 5 is loosened, under the elastic action of the reset spring 3, the slide bar 4 will move toward the direction of the RF DC power supply 7 inside the slide cavity 2, thereby driving the L-shaped plate 5 to move synchronously, and the front end of the L-shaped plate 5 will limit the front end of the RF DC power supply 7. When the L-shaped plate 5 moves, it will drive multiple fixing blocks 6 to move synchronously, squeezing one side of the RF DC power supply 7, thereby moving the RF DC power supply 7 toward the middle position of the structural body 1. Since the specifications of the reset springs 3 on both sides are the same, their elastic forces are also equal, and finally the RF DC power supply 7 can be clamped and fixed at the middle position of the structural body 1, so that there is no need for manual alignment and installation, and the installation position of the RF DC power supply 7 can be well ensured to be centered. The installation accuracy is improved. After the alignment of the RF DC power supply 7 is completed, the protective cover 16 can be opened to rotate the knob 15. The knob 15 will drive the rotating shaft 14 to rotate, and the rotating shaft 14 will drive the threaded rod 9 to rotate. The threaded rod 9 will drive the lifting plate 10 to rotate synchronously. Since the two sides of the lifting plate 10 are slidably matched with the guide rod 11, the lifting plate 10 will be axially limited. The rotation of the lifting plate 10 will be converted into vertical movement up and down. The lifting plate 10 will synchronously drive the lower pressing plate 13 to move through the connecting block 12, so that the lifting plate 10 can move downward. When the RF DC power supply 7 is moved, the lower pressure plate 13 will be moved out of the storage groove 19 to clamp and fix the upper end of the RF DC power supply 7, so that the RF DC power supply 7 can be firmly fixed in the structural body 1, ensuring the firmness after installation. After the installation is completed, the protective cover 16 can be closed without turning the knob 15, so that the protective cover 16 covers the outside of the knob 15, and the protective cover 16 is firmly fixed to the upper end of the structural body 1 through the magnetic adsorption between the magnetic iron sheets 17, avoiding the fixing effect of moving the lower pressure plate 13 due to accidental touching of the knob 15.
