Description

Technical Field

[0001] This utility model relates to the field of satellite technology, and in particular to a satellite down-frequency converter that is easy to combine and use. Background Technology

[0002] As a core infrastructure for modern communication, remote sensing, navigation and other fields, satellites have profoundly changed human life and production. Currently, there are more than 7,000 satellites in orbit around the world, covering various types such as communication satellites, meteorological satellites and remote sensing satellites. With the development of satellite technology, the demand for multiple satellites to work together is increasing, such as satellite constellation networking, to provide more stable and wider signal coverage. This places higher demands on ground receiving equipment. Among them, the satellite downconverter, as a key device in the satellite signal receiving system, has the function of converting the high-frequency signals transmitted by the satellite into intermediate frequency signals that the receiver can process.

[0003] Traditional satellite frequency downconverters use rigid housings and lack effective internal cushioning. When exposed to external impacts and vibrations, components are easily loosened, solder joints detach, or even physically damaged. Furthermore, traditional connection methods are cumbersome, and disassembly and repair are time-consuming. Traditional downconverters also struggle to be compatible with multiple frequency bands, failing to meet users' needs for simultaneous reception of multiple frequency bands and satellite signals. While current market downconverters are designed with modular structures, each module handling specific frequency bands, allowing users to freely combine modules to achieve simultaneous reception of multiple frequency bands, their self-protection remains too rudimentary. External impacts and other factors can damage and dislodge internal components. Additionally, traditional fixed-mount methods involve numerous disassembly steps and are time-consuming during replacement and repair. Utility Model Content

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, firstly, when an external force pushes the circular plate, the circular plate causes the protective sleeve to move downward, thereby causing the medium spring at the bottom to be squeezed and deformed to absorb part of the force. At the same time, it causes the annular perforated plate to move downward. Since the circular hole on the annular perforated plate allows the support column at the bottom to pass through, the large spring on the outer wall of the support column is squeezed and deformed to absorb the force. The two buffer areas complete the buffering of the force.

[0022] 2. In this utility model, after the outer shell 2 is placed into the groove of the installation area, the handle is turned to drive the screw 1 to move downward. Then, the balls on both sides of the bottom of the screw 1 squeeze the small spring and move downward on the inner wall of the outer shell 2. When the abutment reaches the bottom of the outer shell 2, the balls are just in the groove. With the help of the small spring, the balls are popped out and stuck in the groove of the installation area, thus fixing them. Attached Figure Description

[0037] Please see the appendix Figure 1 - Appendix Figure 2 A ring-shaped support plate 17 is firmly fixed to the outer wall of the buffer sleeve 3. A connecting rod 20 is fixed to the top of the outer wall of the ring-shaped support plate 17 by a strong connection. Multiple such connecting rods 20 are all fixedly connected to the top of the connecting sleeve 11. In addition, a screw 18 is installed in the top area of ​​the ring-shaped support plate 17 by a threaded connection. The outer wall of multiple screws 18 is tightly connected to the corresponding nuts 19 by a threaded connection. A friction ring 22 is firmly fixed to the bottom of the base 1. A return spring 23 is installed between two adjacent friction rings 22 by a fixed connection to ensure the normal operation and reset function of the device.

[0038] Specifically, the outer wall of the buffer sleeve 3 is firmly connected to the annular support plate 17, the top of which is firmly connected to the connecting rod 20.

The bottom of the base 1 is fixedly connected to the friction ring 22, and the adjacent friction rings 22 are fixedly connected to the reset spring 23 to maintain the reset function.

[0039] Working principle: When an external force is encountered, it acts on the circular plate 10. Since the circular plate 10 is connected to the protective sleeve 9, the external force pushes the protective sleeve 9 downward. Then, the medium spring 8 connected to the bottom of the protective sleeve 9 moves downward together. During the movement, the medium spring 8 contacts the annular perforated plate 6 and is squeezed, absorbing part of the external force and forming the first buffer area. It then pushes the annular perforated plate 6 to continue moving downward. Then, the circular hole 7 on the annular perforated plate 6 is the same size as the support column 5 at the bottom of the annular perforated plate 6. When the annular perforated plate 6 moves downward, the support column 5 passes through it and squeezes the large spring 4 on the outer wall of the support column 5, deforming it to absorb the remaining force and forming the second buffer area. Through the two layers of buffering, the external force is weakened to the point that it cannot affect the internal equipment, thus avoiding equipment damage.

[0040] When installing the frequency reducer, simply align the groove 202 at the bottom of the base 1 with the groove in the installation area, and then rotate the handle 208. The handle 208 will drive the screw 204 to move downward along the threaded groove 203 on the inner wall of the outer casing 201. After the abutment 205 at the top of the screw 204 touches the ground inside the base 1, the balls 207 on both sides of the screw 204 are squeezed due to the small space inside the outer casing 201 during the movement. When the abutment 205 touches the groove, the balls 207 on both sides move to the groove 202 on both sides of the outer casing 201. Then, with the help of a small spring 206, the balls 207 are ejected and fixed in the groove in the installation area, thus realizing the quick installation of the VC bellows cutting tool. The feature is that a friction ring 22 is fixedly connected to the bottom of the base 1, and a return spring 23 is fixedly connected between the adjacent friction rings 22.
