Abstract
Description
Technical Field
[0001] This utility model relates to the field of resonant rod technology, specifically a resonant rod with a bottom pressing structure. Background Technology
[0002] The resonant rod is an indispensable component in aerospace, broadcasting, and communication base station equipment. Also known as a vibrator, reflector, resonator, or resonant column, it is primarily used in filter products. Its key dimensions, such as diameter and fillet radius, directly affect the product's performance indicators. As a crucial component in aerospace, broadcasting, and communication base station equipment, it plays a vital role in ensuring the stability and quality of communication signals. Resonant rods are typically made from 45# round steel. This material undergoes special treatment to reduce hardness and improve machinability. During manufacturing, the material is first treated, then repeatedly extruded and drawn into a blind-hole cylinder. Finally, the length of the resonant rod is machined. The dimensions and roughness of the stretched resonant rod are completely consistent, exhibiting high density and a low coefficient of expansion, while also reducing costs. As an important electronic component, the resonant rod plays a vital role in filters and communication base station equipment. With continuous technological advancements and innovations, its performance and application scope are expected to further expand.
[0003] In existing technologies, resonant rods are usually fixed by direct fixing. When there are tolerances between the resonant rod connections, mismatch and unstable connections may occur. To address this problem, we propose a resonant rod with a bottom pressing structure. Utility Model Content
[0004] The purpose of this invention is to provide a resonant rod with a bottom pressing structure to solve the problems existing in the prior art as described in the background section.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A resonant rod with a bottom pressing structure includes a resonant rod body and a base. A connecting seat is fixedly connected to the lower end of the resonant rod body. Two arc-shaped grooves are provided through the base. Two pressing devices are fixedly connected to the lower end of the connecting seat at the corresponding positions. A limit device is provided through the bottom of each of the two arc-shaped grooves.
[0007] Preferably, the crimping device includes two connecting columns fixedly connected to the lower end of the connecting seat, and an arc-shaped plate is fixedly connected to the lower end of each of the two connecting columns. The shape and size of the arc-shaped plate match the size of the arc-shaped groove.
[0008] Preferably, the base is composed of two layers, with two limiting posts fixedly connected to the upper end of the lower layer.
[0009] Preferably, the limiting device includes a limiting groove that extends through the bottom of the arc-shaped groove, and the limiting post at the corresponding position is located in the limiting groove, the position of the limiting post corresponding to the position of the arc-shaped plate.
[0010] Preferably, the inner size of the two arc-shaped grooves is twice the size of the opening of the two arc-shaped grooves.
[0011] Preferably, thickened rods are fitted onto the sidewalls of the two limiting posts located within the arc-shaped grooves.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In this invention, by setting up a pressing device and a limiting device to cooperate with each other, the connection between the resonant rod and the base is achieved by the snap-fit of the arc plate and the arc groove. The limiting post on one side can play a limiting role. The limiting post can be fitted with thickened rods of different thicknesses. When there is a tolerance between the snap-fit of the connecting seat and the base, the thickness of the limiting post can be changed to make the connecting post and the arc plate snap-fit tightly, reducing shaking.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Reference Figure 1-4A resonant rod with a bottom pressing structure includes a resonant rod body 1 and a base 3. A connecting seat 2 is fixedly connected to the lower end of the resonant rod body 1. Two arc-shaped grooves are provided through the base 3. Two pressing devices are fixedly connected to the lower end of the connecting seat 2 at corresponding positions. The pressing device includes two connecting posts 5 fixedly connected to the lower end of the connecting seat 2. Arc-shaped plates 7 are fixedly connected to the lower end of the two connecting posts 5. The shape and size of the arc-shaped plates 7 match the size of the arc-shaped groove opening. The size of the two arc-shaped grooves is twice the size of the opening of the two arc-shaped grooves. The arc-shaped plates 7 can also rotate and move inward when they enter the arc-shaped grooves, which facilitates docking.
[0020] The base 3 is composed of two layers 4. Two limiting posts 6 are fixedly connected to the upper end of the lower layer 4. Limiting devices are provided through the bottom of the two arc-shaped grooves. The limiting devices include limiting grooves that are provided through the bottom of the arc-shaped grooves. The limiting posts 6 at the corresponding positions are located in the limiting grooves. The positions of the limiting posts 6 correspond to the positions of the arc-shaped plates 7. Thickened rods are fitted on the side walls of the two limiting posts 6 located in the arc-shaped grooves. The thickened rods can increase the thickness of the limiting posts 6 in the arc-shaped grooves and can be adjusted according to the deviation of the shaking to reduce shaking.
[0021] In this invention, when the resonant rod body 1 is pressed together, the positions of the connecting seat 2 and the base 3 are aligned, and the two arc-shaped plates 7 at the lower end are aligned with the positions of the two arc-shaped grooves respectively. The two arc-shaped plates 7 are pressed into the two arc-shaped grooves and rotated, so that one end of the two arc-shaped plates 7 can enter the interior of the arc-shaped grooves respectively, while the corresponding limiting grooves will be exposed on the other side. At this time, after the two layer plates 4 overlap each other, the corresponding limiting posts 6 can protrude from the two limiting grooves respectively and limit the arc-shaped plates 7. According to the shaking of the arc-shaped plates 7, different thickened rods can be selectively fitted on the limiting posts 6 to make the arc-shaped plates 7 fit tightly.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
