Abstract
Description
Technical Field
[0001] This utility model belongs to the field of duplexer technology, and specifically relates to a duplexer that is easy to install. Background Technology
[0002] As a key component in wireless communication systems, the duplexer plays a crucial role in signal separation and combining. In wireless communication equipment, it cleverly distinguishes between transmitted and received signals within the same frequency band, allowing simultaneous and non-interfering operation of transmission and reception functions, significantly improving the spectrum utilization and overall performance of the communication equipment. Traditionally, duplexers are connected to the device body via soldering or by securing them with numerous screws. Soldering involves directly soldering the duplexer's pins to the circuit board, a relatively secure method that ensures the duplexer won't easily loosen during operation. Screw securing involves drilling holes in the duplexer's casing and mounting bracket, then using screws to fix the duplexer in place for stable installation. However, disassembly is extremely difficult when the device malfunctions and the duplexer needs repair. Each screw must be unscrewed individually with a screwdriver, and rusted or stripped screws further complicate disassembly. Utility Model Content

[0028] This specific embodiment is a duplexer that is easy to install, and its structural diagram is shown below. Figure 1 As shown, it includes a duplexer body 1 and a mounting plate 6. The mounting plate 6 is located at the bottom of the duplexer body 1. A connecting block 5 protrudes from the bottom of the duplexer body 1. The connecting block 5 and the mounting plate 6 can be detachably connected.
[0029] Reference Figure 1 , Figure 2 The mounting plate 6 has a mounting hole 4 near the side inside. A drive rod 3 is slidably installed in the mounting hole 4. A drive block 8 is fixed to the part of the drive rod 3 located deep inside the mounting hole 4. A first spring 7 is installed on the drive block 8 and is fixedly connected to the inner wall of the mounting hole 4. A pressing block 9 is fixedly connected to the rod body of the drive rod 3 located inside the mounting hole 4. A movable block 13 is provided on the sliding path of the pressing block 9. A locking rod 12 is fixedly connected to the other side of the movable block 13 and is locked and fixed to the connecting block 5.
[0030] Reference Figure 2 , Figure 3 , Figure 4 The inner wall of the mounting plate 6 has a movable hole 15 through which the locking rod 12 slides. The side wall of the connecting block 5 has a locking hole 14 adapted to the locking rod 12. The end of the locking rod 12 away from the locking hole 14 is fixedly connected to the movable block 13, and a fixing ring 10 is fixedly fitted onto the outer wall of the end of the locking rod 12 near the movable block 13. A second spring 11 is fixedly connected to the side of the fixing ring 10 away from the movable block 13, and the other side of the second spring 11 is fixedly connected to the inner wall of the mounting plate 6. The second spring 11 is fitted onto the outside of the locking rod 12. A mounting block 2 protrudes from the outer wall of the mounting plate 6. Both the movable block 13 and the pressing block 9 are arc-shaped structures, and their arc surfaces are in contact with each other.
[0031] Working principle: The mounting plate 6 is located at the bottom of the duplexer body 1. A connecting block 5 protrudes from the bottom of the duplexer body 1, which is used to achieve a detachable connection with the mounting plate 6. The outer wall of the mounting plate 6 is provided with a mounting block 2. Before installation, standard fasteners such as bolts can be used to firmly fix the mounting plate 6 to the pre-set position of the wireless communication device body through the mounting block 2, providing a stable foundation for the subsequent installation of the duplexer body 1.
[0032] After the mounting plate 6 is fixed, the duplexer body 1 is installed. First, press the drive rod 3 to disengage the pressing block 9 from the movable block 13. At this time, the second spring 11 extends, causing the locking block to retract along the movable hole 15 toward the interior of the mounting plate 6, bringing the connecting block 5 at the bottom of the duplexer body 1 closer to the mounting plate 6. As the connecting block 5 gradually approaches the mounting plate 6, it will press the locking rod 12. When the connecting block 5 moves to the corresponding position, release the pressure on the drive rod 3. At this time, the pressing block 9 is subjected to the restoring force of the first spring 7 and begins to press the movable block 13. The locking rod 12 at the other end of the movable block 13 engages in the locking hole 14, thereby achieving the locking and fixing of the connecting block 5 and the mounting plate 6, completing the installation of the duplexer body 1. At this time, the duplexer can normally undertake the task of signal separation and combining in the wireless communication system.
[0033] When a wireless communication device malfunctions and requires inspection, replacement, or maintenance of the duplexer, the duplexer body 1 needs to be removed from the mounting plate 6. The operator simply needs to push the drive rod 3, which is installed inside the mounting hole 15 near the side of the mounting plate 6. When the drive rod 3 is pushed, it moves the drive block 8 within the mounting hole 15, simultaneously compressing the first spring 7 to store elastic potential energy.
[0034] During the movement of the drive rod 3, the pressing block 9, which is fixed to the rod body inside the mounting hole 15, moves accordingly. Because the pressing block 9 contacts the arc-shaped surface of the movable block 13, the movement of the pressing block 9 causes misalignment with the movable block 13. After the pressing block 9 is no longer in place, the second spring 11 pops out, and the movable block 13 drives the locking rod 12 to move into the mounting plate 6. As the locking rod 12 moves, it gradually exits from the locking hole 14 of the connecting block 5. When the locking rod 12 is completely out of the locking hole 14, the locking connection between the connecting block 5 and the mounting plate 6 is released. At this point, the operator can easily remove the duplexer body 1 from the mounting plate 6 for subsequent maintenance, replacement, and other operations. After maintenance, the duplexer body 1 is reinstalled onto the mounting plate 6 according to the above installation process to restore normal operation of the equipment.
[0035] All technical features in this embodiment can be freely combined according to actual needs.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
