Description

Technical Field

[0001] This utility model relates to the field of isolator cavities for microwave communication, and in particular to an anti-loosening structure for isolator cavities for microwave communication. Background Technology

[0002] The isolator cavity for microwave communication is a key component of a microwave isolator, used to house and protect internal microwave components and enable specific functions. It is typically a relatively enclosed metal structure that provides a stable operating environment for internal ferrite, coupler, and other components, providing electromagnetic shielding to reduce the impact of external electromagnetic interference on internal components and signal transmission, while preventing internal microwave signal leakage. Its structural design must meet both good electromagnetic performance requirements and consider heat dissipation and anti-loosening needs. Through optimized internal support and clamping mechanisms, it ensures stable operation of components under various conditions, guaranteeing the normal operation of the microwave communication system.

[0003] Currently, cavities are usually fixed with bolts. However, the cavities vibrate during operation, which may cause the bolts to loosen, leading to cavities becoming loose and unable to function properly. In addition, the current cavities lack internal component fixation, which makes the internal components prone to loosening during operation and affecting their normal function.

[0004] In response to this technical problem, this application proposes an anti-loosening structure for the cavity of an isolator used in microwave communication. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-loosening structure for the cavity of an isolator used in microwave communication. This structure aims to prevent the bolts used to fix the cavity from loosening, thereby preventing the cavity from loosening during operation, improving the cavity's robustness, and securing the components to prevent them from loosening during cavity operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A microwave communication isolator cavity anti-loosening structure includes a mounting plate, a cavity is provided on the top side of the mounting plate, two fixing plates are fixedly connected to the left and right sides of the cavity, bolts are provided inside the fixing plates, and the bolts pass through the fixing plates and the mounting plates from top to bottom. Anti-loosening components are provided at the four corners of the top side of the mounting plate to prevent the bolts from loosening. The inner wall of the cavity is connected to clamps for fixing the internal components of the cavity through an adjustment component, and the position of the clamps is adjusted by the adjustment component.

[0008] Furthermore, the anti-loosening component includes round rods fixedly connected to the four corners of the top side of the mounting plate, with a metal plate fixedly connected to the top of the round rods and a sliding rod slidably connected to the middle of the metal plate.

[0009] Furthermore, a plug rod is fixedly connected to the bottom end of the slide rod, a washer is fixedly connected to the top end of the bolt, the plug rod passes through the washer and the mounting plate from top to bottom, and a pull ring is fixedly connected to the top end of the slide rod.

[0010] Furthermore, a spring is fitted on the outer wall of the slide rod, with one end of the spring connected to the bottom side of the metal plate and the other end of the spring connected to the top of the insert rod.

[0011] Furthermore, the adjustment assembly includes multiple telescopic rods fixedly connected to the inner wall of the cavity, and multiple bidirectional screws rotatably connected inside the cavity. The outer wall of each bidirectional screw is threaded with two slide blocks, which are slidably connected to the inner wall of the cavity.

[0012] Furthermore, the clamp plate is sequentially fixedly connected to two rotating seats, which are adjacent to the slide via a connecting rod. One end of the connecting rod is rotatably connected to the middle of the rotating seat, and the other end of the connecting rod is rotatably connected to the middle of the slide.

[0013] Furthermore, the end of the telescopic rod is fixedly connected to one side of the clamping plate, and the top of the bidirectional screw is fixedly connected to a rotating handle, which is rotatably connected inside the cavity.

[0014] Furthermore, mounting blocks for fixing the mounting plate to the equipment are fixedly connected at each of the four corners of the mounting plate, and a cover plate for sealing the cavity is inserted into the top side of the cavity.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, a spring is used to press the insertion rod against the gasket and the mounting plate, so that the insertion rod firmly fixes the gasket and the mounting plate, thereby preventing the bolts used to fix the cavity from loosening, thus preventing the cavity from loosening during operation and improving the firmness of the cavity.

[0017] 2. In this utility model, the slide block is driven to slide up and down by a bidirectional screw, so that the rotating block moves back and forth under the action of the connecting rod, thereby pushing the clamping plate to move back and forth, thus fixing the component and preventing the component from loosening when it is working in the cavity.

A cavity 2 is provided on the top side of the mounting plate 1. Two fixing plates 12 are fixedly connected to the left and right sides of the cavity 2. Bolts 11 are provided inside the fixing plates 12. The bolts 11 pass through the fixing plates 12 and the mounting plate 1 from top to bottom. By passing the bolts 11 through the fixing plates 12 and the mounting plate 1, the cavity 2 is fixed to the mounting plate 1. The inner wall of the cavity 2 is connected to a clamping plate 14 for fixing the internal components of the cavity 2. Round rods 7 are fixedly connected to the four corners of the top side of the mounting plate 1. The top of the round rods 7 is fixedly connected to a metal plate 5. The middle of the metal plate 5 is slidably connected to... A sliding rod 9 is connected to a bottom end of the sliding rod 9, and a pin 10 is fixedly connected to the top end of the bolt 11. A washer 3 is fixedly connected to the top end of the bolt 11. The pin 10 passes through the washer 3 and the mounting plate 1 from top to bottom. The bolt 11 is fixed by inserting the pin 10 into the washer 3 and the mounting plate 1, thereby preventing the bolt 11 from loosening. A pull ring 13 is fixedly connected to the top end of the sliding rod 9. The sliding rod 9 is slid by pulling the pull ring 13, thereby causing the pin 10 to disengage from the washer 3 and the mounting plate 1. A spring 8 is sleeved on the outer wall of the sliding rod 9. One end of the spring 8 is connected to the bottom side of the metal plate 5, and the other end of the spring 8 is connected to the top end of the pin 10. The spring 8 is used to press the pin 10 against the washer 3 and the mounting plate 1.

[0026] Reference Figure 1 , Figure 3 and Figure 4 Multiple telescopic rods 20 are fixedly connected to the inner wall of cavity 2. Multiple bidirectional screws 18 are rotatably connected inside cavity 2. Two slides 17 are threadedly connected to the outer wall of the bidirectional screws 18. The slides 17 are slidably connected to the inner wall of cavity 2. The slides 17 are slidable by the bidirectional screws 18. Two rotating seats 16 are fixedly connected to clamping plate 14 in sequence. The rotating seats 16 and the slides 17 are adjacent to each other by connecting rod 19. One end of connecting rod 19 is rotatably connected to the middle of rotating seat 16, and the other end of connecting rod 19 is rotatably connected to the middle of slide 17. The slides 17 are moved up and down by connecting rod 19. When sliding, the rotating seat 16 is pushed to move back and forth, thereby causing the clamping plate 14 to move back and forth. The end of the telescopic rod 20 is fixedly connected to one side of the clamping plate 14. The telescopic rod 20 further secures the clamping plate 14 more firmly without affecting the back and forth movement of the clamping plate 14. The top of the bidirectional screw 18 is fixedly connected to the handle 15, which is rotatably connected inside the cavity 2. The handle 15 is used to rotate the bidirectional screw 18. Mounting blocks 4 for fixing the mounting plate 1 to the equipment are fixedly connected at the four corners of the mounting plate 1. A cover plate 6 for sealing the cavity 2 is inserted into the top side of the cavity 2.

[0027] Working principle: First, place the mounting plate 1 on the surface of the device where the cavity 2 needs to be installed. Then, pass the screw through the mounting block 4 and transmit it into the device. Turn the nut onto the screw to fix the mounting plate 1 to the device surface. Next, place the cavity 2 on the mounting plate 1. Then, pull the pull ring 13 to disengage the insertion rod 10 from the mounting plate 1. Then, pass the bolt 11 through the fixing plate 12 and the mounting plate 1 to fix the cavity 2 to the mounting plate 1. Finally, release the pull ring 13 to allow the insertion rod 10 to insert into the washer 3 and the mounting plate 1 under the action of the spring 8. Secure bolt 11 to prevent it from loosening. After the cavity 2 is fixed, remove cover plate 6 from the cavity 2. Then place the required components into the cavity 2 and position them between the front and rear clamping plates 14. Then rotate handle 15 to rotate double screw 18, thereby causing slide 17 to slide. Under the action of connecting rod 19, when slide 17 slides up and down, it will push rotating base 16 to move back and forth, thereby causing clamping plate 14 to move back and forth until the components are fixed, thus preventing the components from loosening when the cavity 2 is working.
