[0017] 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 implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0018] Example

[0019] See also Figure 1-4 , as shown in the figure: This embodiment is a preferred implementation of the technical solution, a radio frequency amplifier, including a radio frequency amplifier body 12 and a mounting assembly for mounting the radio frequency amplifier body 12; the mounting assembly includes a bottom plate 1, a combined housing 5 movably arranged on the upper side of the bottom plate 1, an "L"-shaped support member 9 fixed below the inner side wall of the combined housing 5, an adjustment knob 7 arranged at the middle position of the upper side edge of the combined housing 5, and a positioning disk 10 fixed to the inner end of the adjustment knob 7; the radio frequency amplifier body 12 is located inside the combined housing 5; a conical frame 8 is fixed in the middle of the lower side of the bottom plate 1, a base 14 is fixed at the bottom of the conical frame 8, and the top opening of the conical frame 8 corresponds to the middle opening of the bottom plate 1;

[0020] It should be noted that: in the RF amplifier involved in the present application, by adding an installation component to the outside of the RF amplifier body 12, the RF amplifier body 12 is convenient for loading and unloading, and external protection of the RF amplifier body 12 can be achieved. The heat dissipation channel provided in the installation component facilitates the heat dissipation of the RF amplifier body 12, which has great practical value. When used specifically, the position of the combined housing 5 is adjusted, and the ends of the RF amplifier body 12 are placed on the "L"-shaped support members 9 inside the combined housing 5, and then the combined housing 5 is pushed closer to each other until they collide. At this time, the combined housing 5 and the RF amplifier body 12 automatically cooperate, and then the position of the positioning disk 10 is adjusted by adjusting the knob 7 until the positioning disk 10 conflicts with the upper side of the RF amplifier body 12.

[0021] Among them Figure 1 As shown, a mounting sleeve 4 is fixed to the middle of the lower edge of the side of the combined housing 5, a guide rod 3 is sleeved inside the mounting sleeve 4, an ear seat 2 is fixed to the end of the guide rod 3, and the ear seat 2 is fixed to the upper side of the bottom plate 1;

[0022] It should be noted that the ear seat 2 is used to install and fix the guide rod 3, and the guide rod 3 limits the combined shell 5 through the mounting sleeve 4. When the combined shells 5 approach or move away from each other, the mounting sleeve 4 moves linearly along the guide rod 3, and there is a certain damping effect between the mounting sleeve 4 and the surrounding side of the guide rod 3, so that the combined shell 5 maintains a fixed relative position when not pushed or pulled by external force. A spring reset structure can also be installed between the mounting sleeve 4 and the ear seat 2 to assist in resetting the combined shell 5, which will not be described in detail here.

[0023] Among them Figure 2 and Figure 3 As shown, the bottom side of the combined housing 5 is hollowed out to provide an air inlet grille 11, and the side of the combined housing 5 is provided with an air outlet grille 6; a semi-arc notch is provided in the middle of the combined housing 5, and the terminal 13 of the RF amplifier body 12 matches the semi-arc notch; the lower side of the RF amplifier body 12 is fitted with the horizontal branch of the "L"-shaped support member 9, and the upper side of the RF amplifier body 12 is in contact with the positioning disc 10;

[0024] It should be noted that: the combined housing 5 is symmetrically arranged outside the end of the RF amplifier body 12. When the two combined housings 5 ​​are assembled with the RF amplifier body 12, the horizontal branch of the "L"-shaped support member 9 supports the bottom of the RF amplifier body 12, and the vertical branch of the "L"-shaped support member 9 separates the side of the RF amplifier body 12 from the inner wall of the combined housing 5 to ensure air circulation inside the combined housing 5. The positioning disk 10 limits the upper side of the RF amplifier body 12 to prevent the RF amplifier body 12 from shaking inside the combined housing 5. At the same time, when the two combined housings 5 ​​are assembled with the RF amplifier body 12, the semi-arc notches arranged in the middle of the two combined housings 5 ​​are combined to form a circular hole structure, which is wrapped around the outside of the terminal 13.

[0025] Among them Figure 4 As shown, the circumference of the conical frame 8 is hollowed out, and a fan is provided in the upper end of the conical frame 8;

[0026] It should be noted that the hollowing out of the circumference of the conical frame 8 allows external airflow to enter the conical frame 8 to form airflow when the fan is started. The fan serves as a heat dissipation structure of the RF amplifier body 12. The fan is a relatively conventional structure at present. The specific model and size are determined according to actual usage requirements, and no restrictive description is made here.
