Description

Technical Field

[0001] The utility model mainly relates to the field of electronic components, and in particular to a fixing mechanism for a duplexer. Background Art

[0002] The duplexer is the main accessory of the duplex radio and repeater. Its function is to isolate the transmitting and receiving signals to ensure that both the receiving and transmitting can work normally at the same time. It is composed of two sets of bandpass filters with different frequencies to prevent the local transmitting signal from being transmitted to the receiver. The duplexer is a relatively special two-way three-terminal filter. The duplexer must not only couple the weak receiving signal, but also feed the larger transmitting power to the antenna, and require both to complete their functions without affecting each other. The general duplexer is composed of a spiral resonator cavity. Due to its high operating frequency and the large influence of distributed parameters, it is often made into a sealed sleeve. The general duplexer is composed of six band-stop filters (notch filters), each resonating at the transmitting and receiving frequencies.

[0003] In the invention patent application with application number CN202221543984.4, application publication date 2022.12.09, and name "A duplexer easy to install", it includes a duplexer body, a mounting mechanism, which is arranged on the side wall of the duplexer body, and the mounting mechanism includes a side plate, which is fixedly installed on the side wall of the duplexer body, an inner block, which is arranged inside the side plate, a fixed block, which is fixedly installed on the upper surface of the inner block, a threaded rod, which is fixedly installed on the upper surface of the fixed block, a knob, which is arranged at the upper end of the threaded rod, and a rubber ring is arranged at the bottom of the knob, a connecting block, which is fixedly installed on the right wall of the inner block, and a mounting plate, which is fixedly installed on the right wall of the connecting block, and a mounting hole is opened on the upper surface of the mounting plate. The device is arranged by the installer turning the knob to disengage the knob from the upper end of the threaded rod. At this time, the installer pushes the threaded rod to move the inner block along the moving opening, thereby driving the mounting plate to move, so that the installer can adjust the position of the mounting plate according to the position of the reserved hole for installing the duplexer, thereby improving the efficiency of duplexer installation and making the installation of the duplexer more convenient.

[0004] However, during the actual installation of the duplexer, the disassembly process is cumbersome and the installation is inconvenient. The use of rubber pads can also easily lead to heat dissipation difficulties for the duplexer. Utility Model Content

[0005] 1. Technical problems to be solved by the utility model:

[0006] The utility model provides a fixing mechanism for a duplexer, which is used to solve the problems that the disassembly process is complicated, the installation is inconvenient, and the use of rubber pads easily leads to heat dissipation difficulties for the duplexer.

[0007] 2. Technical solution:

[0008] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is: a fixing mechanism of a duplexer, including an air-spaced seat, a duplexer body on the surface of the air-spaced seat, joints are arranged on the surfaces of both ends of the duplexer body, a vent is arranged on the surface of the air-spaced seat, a lower supporting fork is installed at the bottom of the air-spaced seat, a disassembly device is arranged inside the air-spaced seat on one side of the lower supporting fork, and an upper fixing fork is fixedly connected to the top of the air-spaced seat.

[0009] Furthermore, the lower support forks and upper fixed forks are respectively provided in the same number at both ends of the spacer and in corresponding vertical positions. The duplexer body is installed on the surface of the spacer through the lower support forks and the upper fixed forks, and a traction top rod is provided on the surface of the spacer.

[0010] Furthermore, the lower support fork includes a mounting groove arranged on the outside of the spacer seat, a socket is arranged on one side surface of the mounting groove, a telescopic rod is movably connected to the lower end surface of the mounting groove, the telescopic rod is sleeved with a support spring inside the mounting groove, a limiting block is fixedly connected to the top surface of the telescopic rod, a traction hole is arranged on the surface of the limiting block, and an outward-turning plug block is fixedly connected to the bottom of the telescopic rod.

[0011] Furthermore, the number of the telescopic rod, the support spring, the limit block and the outward-turning plug block is consistent with that of the upper fixed fork, and the telescopic rod forms an elastic lifting structure on the surface of the installation groove through the support spring.

[0012] Furthermore, the disassembly device includes a positioning slider arranged on the surface of the mounting groove, a pushing block is slidably connected to the surface of the positioning slider, an annular groove body is fixedly connected to the surface of the mounting groove on the other side of the pushing block, an external hole is arranged on one side surface of the pushing block, and a push rod block is fixedly connected to the bottom of the pushing block.

[0013] Furthermore, the external connection hole and the traction hole are arranged on the same horizontal plane and are also at the same level as the plug hole. The external connection hole, the traction hole and the plug hole are interconnected by a traction push rod, and the limit block forms a lifting structure inside the installation groove through the movement of the push rod block.

[0014] 3. Beneficial effects:

[0015] The utility model has a reasonable design. When installing the duplexer, the buckle groove at the lower end of the duplexer buckles the outward-turned plug block in the lower supporting fork and then pulls it upward, driving the telescopic rod and the limit block above the outward-turned plug block to move upward, and then the buckle groove above the duplexer body is clamped on the surface of the lower supporting fork. Under the action of the supporting spring, the outward-turned plug block and the telescopic rod move downward, and the duplexer body is installed on the outer surface of the installation groove through the outward-turned plug block and the upper fixing fork. While the duplexer is quickly installed, the duplexer is cooled through the vents at the rear of the installation groove, thereby achieving the purpose of cooling while quickly installing.

[0016] When the duplexer needs to be disassembled, the traction push rod is inserted into the plug hole into the installation groove. The amount of the traction push rod inserted into the lower support fork is adjusted on the surface of the installation groove, thereby controlling the amount of movement of the lower support fork, pushing the push rod block to drive the push block to slide, and then controlling the traction push rod of the external hole on the surface of the push block to rise or fall on the surface of the annular groove body, and finally driving the limit block to rise and pull the outward-turned plug block to move upward, thereby releasing the lower connection of the duplexer and achieving the purpose of quick disassembly.
