[0001] The utility model relates to the technical field of couplers, in particular to a novel microstrip coupler for a wireless intercom system. Background Art

[0002] Couplers are a common passive device in microwave system circuits and are widely used in mobile communication terminals, base stations, radars and other equipment. Microcouplers include directional couplers, power dividers and various microwave branching devices. These different types of couplers are designed according to their specific functions and application requirements. They play an indispensable role in modern communication technology. Whether in power distribution in microwave systems or signal transmission in optical communications, microcouplers are key components to ensure signal quality and system performance.

[0003] However, the following problems still exist in actual use:

[0004] (1) When the existing micro coupler is in use, the wires connected to the device are mostly connected to it by plugging, which may cause the wires to loosen when the device is impacted by the external environment, resulting in low practicality of the device in actual use.

[0005] (2) When the existing micro coupler is in use, the cover plate on the top is fixedly connected to the shell by nuts, which makes the later inspection and maintenance of its internal parts more complicated, resulting in the problem that the existing micro coupler is less convenient to use.

[0006] For this reason, the utility model introduces a novel microstrip coupler for a wireless intercom system. Utility Model Content

[0008] The utility model provides the following technical solution: a novel microstrip coupler for a wireless intercom system, comprising: a device body, both ends of the device body are provided with plug-in conduits, the outer surface of the plug-in conduit is provided with a clamping mechanism, the clamping mechanism comprises a fixed frame, a rotating shaft, a rotating arm and an extrusion roller, the bottom of the fixed frame is fixedly installed with the outer surface of the plug-in conduit, the outer surfaces at both ends of the rotating shaft are rotatably connected with the inner wall of the fixed frame, the inner wall of the rotating arm is fixedly connected with the outer surface of the rotating shaft, and the two ends of the extrusion roller are rotatably connected with the inner wall of one end of the rotating arm.

[0009] Preferably, a sealing mechanism is provided inside the device body, and the sealing mechanism includes a connecting block, a rotating block, a limiting shaft and a linkage shaft, one side of the connecting block is fixedly installed on the inner wall of the device body, the side surface of the rotating block is fitted with the other side of the connecting block, the outer surface of the limiting shaft is rotatably connected to the inner wall of the rotating block, the outer surface of one end of the limiting shaft is fitted with the inner wall of the connecting block, and one end of the linkage shaft is fixedly connected to the inner wall of the rotating block.

[0010] Preferably, a telescopic spring is fixedly connected to the inner wall of the outer surface of the plug-in catheter, one end of the telescopic spring is fixedly connected to an extrusion block, the bottom of the extrusion block is slidably connected to the bottom of the inner wall of the plug-in catheter, and both ends of the extrusion block are fixedly connected to extension rods.

[0011] Preferably, connecting frames are fixedly installed on both sides of the device body, the inner wall of the connecting frame is rotatably connected to a connecting arm rod, and the inner wall of one end of the connecting arm rod is in contact with the outer surface of the extension rod.

[0012] Preferably, a sealing cover plate is fixedly connected to the top of the rotating block, the outer surface of the sealing cover plate is fitted with the inner wall of the device body, the bottom of the sealing cover plate is fixedly connected to an auxiliary support block, and the side of the auxiliary support block is fixedly connected to the side of the top of the rotating block.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The novel microstrip coupler of the wireless intercom system is provided with a clamping mechanism. When in use, the wire is first inserted into the inside of the plug-in conduit, and then the multiple groups of connecting arm rods are rotated to release the limit on the extension rod, and then the extrusion block connected to one end of the telescopic spring is pushed to move along the trajectory of the inner wall of the outer surface of the plug-in conduit under the elastic force of the telescopic spring, and during the movement of the extrusion block, the inclined surface on the top of the extrusion block will squeeze the extrusion roller, thereby controlling one end of the rotating arm rod to lift and the other end of the rotating arm rod to drop, so that the other end of the rotating arm rod clamps the outer surface of the wire plugged in the plug-in conduit to stabilize it, effectively solving the problem that in actual use, the wires connected to the device are mostly connected to it in a plug-in manner, which causes the device to loosen when it is impacted by the external environment, thereby causing the device to have low practicality in actual use. The wires connected to the device can be further reinforced during the entire operation process, thereby preventing the device from loosening when it is impacted by the outside, thereby improving the stability of the device during operation, thereby greatly improving the practicality of the device.

[0016] 2. The novel microstrip coupler of the wireless intercom system is provided with a sealing mechanism. When it is necessary to repair and inspect the parts inside the main body of the device during use, the lifting handle is pulled upward to drive the sealing cover plate and the rotating block connected to the bottom of the sealing cover plate to move upward together, and when the limit shaft in the inner wall of the rotating block contacts the top of the inner wall of the connecting block, the lifting handle is flipped backward to control the sealing cover plate to rotate backward. At the same time, when the sealing cover plate rotates, the bottom end of the rotating block connected to the bottom thereof and the linkage shaft connected to the inner wall of the bottom end thereof will move to the other end of the inner wall of the connecting block, thereby realizing the rapid opening of the sealing cover plate, effectively solving the problem that in actual use, the cover plate on the top of the device is fixedly connected to the subject by a nut, which leads to a cumbersome process for the later inspection and maintenance of its internal parts, thereby causing the existing micro coupler to be less convenient in use. The sealing cover plate can be conveniently opened and closed during the entire operation process, thereby facilitating the later inspection and maintenance of the electronic components inside the sealing cover plate, thereby greatly improving the convenience of the device.
