[0002] Pulse width modulation is an analog control method that modulates the bias of the transistor base or MOS tube gate according to the change of the corresponding load to achieve a change in the conduction time of the transistor or MOS tube, thereby changing the output of the switching regulated power supply. This method can keep the output voltage of the power supply constant when the operating conditions change. It is a very effective technology for controlling analog circuits using digital signals from microprocessors. It is widely used in many fields from measurement and communication to power control and conversion.

[0003] When an existing klystron amplifier is damaged and needs repair, since the device housing is usually connected to the device with specific screws, specific disassembly tools are required for disassembly. The disassembly process is cumbersome and it is inconvenient for workers to open the housing and replace or repair the internal electronic components. Utility Model Content

[0011] Preferably, the vertical cross-sections of the limiting plate and the rotating plate are both L-shaped structures.

[0012] The technical effects and advantages of this utility model are:

[0013] In the utility model, the staff slides the outer shell to the top of the bottom plate and places it on the top of the frame plate, and then the staff rotates the rotating plate to one side to rotate on the surface of the rotating column, so that the rotating plate pulls the spring to store force. When the staff moves the position of the rotating plate to the top of the limit plate, the staff releases the force generated by the spring, causing the spring to rebound and pull the rotating plate to move, so that the bottom of the rotating plate is inserted into the inner wall of the limit plate, thereby limiting the position of the outer shell to the top of the bottom plate, realizing rapid installation of the outer shell, so that the staff can remove the outer shell and open the protection of the shell on the bottom plate, thereby repairing the main body substrate inside the shell, and facilitating the staff to disassemble or install the shell.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0021] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, the utility model provides a technical solution: a pulse width modulation type klystron amplifier, comprising a base plate 1, a main body substrate 2 is fixedly connected to the top of the base plate 1, a mounting plate 3 is installed at the front end of the base plate 1, a frame plate 4 is installed at the rear end of the mounting plate 3, a limit plate 5 is fixedly connected to the rear end of the base plate 1, a shell 6 is installed at the top of the base plate 1, a rotating column 7 is fixedly connected to the rear end of the shell 6, a rotating plate 8 is rotatably connected to the surface of the rotating column 7, an extension plate 9 is fixedly connected to the rear end of the shell 6, an arc rod 10 is fixedly connected to one side of the rotating plate 8, a spring 11 is fixedly connected to the bottom of the extension plate 9, and the other end of the arc rod 10 is fixedly connected to the surface of the spring 11. The staff can rotate the shell 6. It slides to the top of the bottom plate 1 and is placed on the top of the frame plate 4. The staff then rotates the rotating plate 8 to one side and rotates it on the surface of the rotating column 7, so that the rotating plate 8 pulls the spring 11 to store force. When the staff moves the position of the rotating plate 8 to the top of the limit plate 5, the rotating plate 8 is released and the force generated by the spring 11 is released, so that the spring 11 rebounds and pulls the rotating plate 8 to move, so that the bottom of the rotating plate 8 is inserted into the inner wall of the limit plate 5, thereby limiting the position of the shell 6 to the top of the bottom plate 1, realizing rapid installation of the shell 6, so that the staff can remove the shell 6 and open the protection of the shell 6 on the bottom plate 1, thereby repairing the main substrate 2 inside the shell 6, making it convenient for the staff to disassemble or install the shell 6.

[0022] Reference Figure 3 As shown, in this embodiment: a slide groove 12 is opened in the middle of the rotating plate 8, and the surface of the spring 11 is slidably connected to the inner wall of the slide groove 12. The sliding connection between the slide groove 12 and the spring 11 is achieved through the sliding connection of the staff, and the position of the rotating plate 8 and the rotating column 7 is moved at the center. At the same time, the spring 11 is set with the rotating column 7 as the center, so that when the rotating plate 8 rotates and moves, it can move on the surface of the spring 11, and the moving trajectory of the rotating plate 8 is restricted, so that the plug-in of the rotating plate 8 and the limit plate 5 is accurate enough to prevent the position of the rotating plate 8 from being offset from the limit plate 5 when rotating.

[0023] Reference Figure 3 As shown, in this embodiment: a threaded hole 13 is provided at one end of the shell 6, and a threaded rod 14 is threadedly connected to the inner wall of the threaded hole 13. When the staff inserts the rotating plate 8 into the limiting plate 5, the threaded rod 14 is screwed to the right side of the rotating plate 8 through the threaded hole 13, and the rotating plate 8 is abutted, so that the threaded rod 14 limits the position of the rotating plate 8 within the limiting plate 5, thereby preventing the device from being vibrated and causing the arc rod 10 to loosen, causing the rotating plate 8 to separate from the limiting plate 5.

[0024] Reference Figure 3As shown, in this embodiment: a rounded corner 15 is provided at one end of the limit plate 5. By providing the rounded corner 15 on one side of the limit plate 5, the end of the rotating plate 8 that contacts the limit plate 5 is rounded and smooth. When the rotating plate 8 contacts the limit plate 5, the rotating plate 8 can slide into the limit plate 5 more easily due to the characteristics of the rounded corner 15, thereby improving the smoothness of the operation of the assembly and making it easier for the staff to rotate the plate 8 and plug it into the limit plate 5.

[0025] Reference Figure 4 and Figure 5 As shown, in this embodiment: both ends of the top of the base plate 1 are fixedly connected to the guide rails 16, and both ends of the bottom of the shell 6 are fixedly connected to the plug plates 17. When the staff installs the shell 6 on the top of the base plate 1, the staff slides the plug plates 17 into the bottom of the guide rails 16, so that the guide rails 16 limit the position of the shell 6 on the top of the base plate 1, thereby preventing the position of the shell 6 from loosening and shifting after the base plate 1 is connected to the shell 6.

[0026] Reference Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment: an acrylic glass plate 18 is installed on the top of the shell 6. The transparent nature of the acrylic glass plate 18 allows the staff to directly observe the operating status of the main body substrate 2 inside the shell 6 through the acrylic glass plate 18, which is convenient for the staff to observe the status inside the shell 6. The staff can observe the operating status of the main body substrate 2 without disassembling the shell 6, which is convenient for the staff to inspect the main body substrate 2 and promptly discover and repair any operating failure of the main body substrate 2.

[0027] Reference Figure 3 and Figure 5 As shown, in this embodiment: the vertical cross-sections of the limit plate 5 and the rotating plate 8 are both L-shaped structures. Through the L-shaped structure setting of the limit plate 5 and the rotating plate 8, the rotating plate 8 and the limit plate 5 can fit tightly at an angle when connected, and at the same time cannot move backward and separate, making the operation of the component more clever and simple, and convenient for staff to operate.

[0028] Working principle: The staff slides the shell 6 to the top of the bottom plate 1 and places it on the top of the frame plate 4, and then the staff rotates the rotating plate 8 to one side to rotate on the surface of the rotating column 7, so that the rotating plate 8 pulls the spring 11 to store force. When the staff moves the position of the rotating plate 8 to the top of the limit plate 5, the rotating plate 8 is released and the force generated by the spring 11 is released, so that the spring 11 rebounds and pulls the rotating plate 8 to move, so that the bottom of the rotating plate 8 is inserted into the inner wall of the limit plate 5, thereby limiting the position of the shell 6 to the top of the bottom plate 1, realizing the rapid installation of the shell 6, so that the staff can remove the shell 6 and open the protection of the shell 6 on the bottom plate 1, thereby repairing the main body substrate 2 inside the shell 6, which is convenient The staff disassembles or installs the shell 6, and the staff slides the connection with the spring 11 through the staff slide groove 12, and moves the position center of the rotating plate 8 and the rotating column 7. At the same time, the spring 11 is set with the rotating column 7 as the center, so that when the rotating plate 8 rotates and moves, it can move on the surface of the spring 11, and limit the movement trajectory of the rotating plate 8, so that the insertion of the rotating plate 8 and the limit plate 5 is accurate enough to prevent the rotating plate 8 from deviating from the position of the limit plate 5 when rotating. When the staff inserts the rotating plate 8 into the limit plate 5, the threaded rod 14 is screwed to the right side of the rotating plate 8 through the threaded hole 13, and the rotating plate 8 is abutted, so that the threaded rod 14 limits the position of the rotating plate 8 within the limit plate 5, thereby preventing the device from being affected. The vibration causes the arc rod 10 to loosen, causing the rotating plate 8 to separate from the limit plate 5. The rounded corner 15 opened on one side of the limit plate 5 makes the end of the rotating plate 8 in contact with the limit plate 5 rounded and smooth. When the rotating plate 8 contacts the limit plate 5, the rotating plate 8 can slide into the limit plate 5 more easily through the characteristics of the rounded corner 15, thereby improving the smoothness of the operation of the assembly and facilitating the staff to rotate the plate 8 and plug the limit plate 5. When the staff installs the shell 6 on the top of the base plate 1, the staff slides the plug plate 17 into the bottom of the guide rail 16, so that the guide rail 16 limits the position of the shell 6 on the top of the base plate 1, thereby preventing the position of the shell 6 from loosening and deviating after the base plate 1 is connected to the shell 6. 6, the acrylic glass plate 18 is transparent so that the staff can directly observe the operating status of the main body substrate 2 inside the shell 6 through the acrylic glass plate 18, which is convenient for the staff to observe the internal status of the shell 6, so that the staff can observe the operating status of the main body substrate 2 without removing the shell 6, which is convenient for the staff to inspect the main body substrate 2 and timely discover and repair the main body substrate 2 when it fails. The L-shaped structure of the limit plate 5 and the rotating plate 8 makes it possible for the rotating plate 8 and the limit plate 5 to fit tightly when they are connected at an angle, and cannot move backward and separate, making the assembly operation more clever and simple, and convenient for the staff to operate.
