An adjustable-pitch resonator

Abstract

This utility model discloses an adjustable-gap resonator, relating to the field of microwave radio frequency technology. It includes a fixed base with a groove along its axis. A bidirectional lead screw, driven to rotate by a rotary motor, is located within the groove of the fixed base. One end of the bidirectional lead screw has a large gear. The outer wall of the large gear has an adjustment component on one side of the fixed base for fine adjustment. The outer wall of the bidirectional lead screw has two sets of opposing threaded ribs. A mounting seat, movable within the groove of the fixed base, is located on the outer wall of the bidirectional lead screw. A resonant column is located on the top surface of the mounting seat. The rotation of the bidirectional lead screw mounted on the fixed base, driven by the rotary motor, causes the mounting seat and the resonant column to move along the direction of the groove in the fixed base, adjusting the gap between the two sets of resonant columns to achieve different frequency transmissions. When the movement is inaccurate, the adjustment component can be manually rotated to drive the large gear to rotate, achieving fine adjustment through a small-to-large rotation.

Description

Technical Field

[0001] This utility model relates to the field of microwave radio frequency technology, and in particular to an adjustable-pitch resonator. Background Technology

[0002] Resonators are widely used in many electronic devices such as communications, radar, and electronic warfare, and their performance directly affects the operation of these devices. Traditional resonators typically employ a fixed structure design, and once their resonant frequency is determined, it is difficult to adjust during use.

[0003] However, when using existing adjustable-gap resonators, the position of the resonator can be adjusted significantly by sliding rails. When the frequency transmission is unclear, adjusting the gap through the equipment will result in the gap being too large or too small, requiring multiple calibrations. Therefore, an adjustable-gap resonator is needed. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-gap resonator, which solves the problem in the prior art where the resonator position cannot be precisely adjusted, resulting in repeated adjustments.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable pitch resonator, comprising a fixed base with a groove along its axis, wherein a bidirectional lead screw that can be driven to rotate by a rotary motor is provided in the groove of the fixed base, one end of the bidirectional lead screw is provided with a large gear, and the outer wall of the large gear is provided with an adjustment component that can be finely adjusted on one side of the fixed base.

[0006] Preferably, the outer wall of the bidirectional lead screw is provided with two sets of opposing threaded ribs.

[0007] Preferably, the outer wall of the bidirectional lead screw is provided with a mounting seat that moves within the groove of the fixed base, and the top surface of the mounting seat is provided with a resonant column.

[0008] Preferably, the cross-section of the mounting base is T-shaped.

[0009] Preferably, one side of the fixed base is provided with a dustproof shell that encloses the large gear for protection.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The rotating motor drives the bidirectional lead screw mounted on the fixed base to rotate, which in turn moves the mounting base and the resonant column along the direction of the groove in the fixed base. The distance between the two sets of resonant columns can be adjusted to achieve transmission of different frequencies. When the movement is not precise, the adjustment component can be manually rotated to drive the large gear to rotate, so as to achieve fine adjustment by using a small gear to drive a large gear.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model relates to an adjustable-pitch resonator, such as... Figure 1-3 As shown, the device includes a fixed base 1 with a groove inside along the axial direction, a bidirectional lead screw 2 installed along the axial direction of the groove in the fixed base 1, the outer wall of the bidirectional lead screw 2 being rotatably connected to the fixed base 1, a bearing being installed at the connection between the fixed base 1 and the bidirectional lead screw 2, allowing the bidirectional lead screw 2 to rotate inside the fixed base 1, and one end of the bidirectional lead screw 2 being fixedly connected to the output end of a rotary motor 3 to drive the bidirectional lead screw 2 to rotate actively.

[0018] Furthermore, the outer wall of the bidirectional lead screw 2 is provided with two sets of opposing threaded ribs, and the outer wall of the bidirectional lead screw 2 is fitted with a mounting seat 4. The interior of the mounting seat 4 is provided with a threaded groove that matches the bidirectional lead screw 2. A resonant column 5 is installed on the top surface of the mounting seat 4. The lower end of the resonant column 5 is screwed to the mounting seat 4, and the resonant column 5 can be screwed to disassemble and install it. There are two sets of mounting seats 4 and resonant columns 5, and the two sets of mounting seats 4 and resonant columns 5 are symmetrically distributed about the midpoint of the bidirectional lead screw 2.

[0019] Furthermore, a dust cover 6 is installed on one side of the fixed base 1. The dust cover 6 is connected to the fixed base 1 by bolts. An adjustment component 7 is located inside the dust cover 6 on one side of the fixed base 1. A large gear 8 that works with the adjustment component 7 is fixedly connected to the outer wall of the other end of the bidirectional lead screw 2. The adjustment component 7 and the large gear 8 work together to adjust the position of the resonant column 5, mainly for fine adjustments.

[0020] Among them, such as Figure 3 As shown, the adjustment assembly 7 includes a pinion 701, a rotating shaft 702, and a turntable 703. The pinion 701 is sleeved on the outer wall of the rotating shaft 702. The outer wall of the rotating shaft 702 is fixedly connected to the inner wall of the pinion 701. The turntable 703 is fixedly connected to the outer wall of the rotating shaft 702 on one side of the pinion 701. The outer wall of the pinion 701 meshes with the outer wall of the large gear 8. By controlling the turntable 703, the rotating shaft 702 and the pinion 701 are rotated, thereby causing the large gear 8 to drive the bidirectional lead screw 2 to rotate, thus achieving the purpose of adjusting the spacing of the resonant columns 5.

[0021] In practical use: the bidirectional lead screw 2 mounted on the fixed base 1 is driven to rotate by the rotary motor 3, which drives the mounting base 4 and the resonant column 5 to move along the direction of the groove opened on the fixed base 1. The distance between the two sets of resonant columns 5 can be adjusted to achieve transmission of different frequencies. When the movement is not precise, the adjustment component 7 can be manually rotated to drive the large gear 8 to rotate, so as to achieve the purpose of fine adjustment by using a small rotation to drive a large rotation.
