[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.
[0025] Depend on Figure 1 and Figure 2 As shown, it is a structural schematic diagram of the radio frequency interface bracket in this embodiment, including a base 1, a support plate 2 and a height extension bracket 3. The support plate 2 is slidably installed in the base 1, and the height extension bracket 3 is installed on the side of the base 1.
[0026] In use, the base 1 is placed on a predetermined platform, and then the attenuator or adapter to be supported is installed on the surface of the support plate 2. With the calibration and limitation of the height extension frame 3, the attenuator or adapter is installed inside the base 1 in a posture parallel to the base 1. The structure of the height extension frame 3 and the support plate 2 are coordinated to flexibly adjust the installation height of the attenuator or adapter, thereby providing stable support and positioning for the attenuator or adapter.
[0027] From the appendix Figure 3 As shown, it is a structural schematic diagram of the height extension frame 3 in this embodiment. The height extension frame 3 includes extension rod type A 31 and extension rod type B 32. Extension rod type A 31 is installed on the side of the base 1, and extension rod type B 32 is installed on the other side of the base 1. Extension rod type A 31 and extension rod type B 32 are symmetrically arranged about the center of the base 1.
[0028] During use, extension rods A-type 31 and B-type 32 are installed on both sides of the base 1 to provide support and limit the installation of the bearing plate 2, allowing the bearing plate 2 to slide vertically up and down along the inner wall of extension rods A-type 31 and B-type 32, ensuring that the attenuator or adapter is in a parallel state during installation, which facilitates stable connection between the attenuator or adapter and the line.
[0029] From the appendixFigure 3 As shown, it is a structural schematic diagram of the height extension frame 3 in this embodiment. The height extension frame 3 also includes a motion groove 33. The inner walls of the extension rod type A 31 and extension rod type B 32 are provided with motion grooves 33 that cooperate with the sliding of the bearing plate 2. In use, the side of the bearing plate 2 fits against the motion groove 33 to assist the bearing plate 2 in sliding up and down stably.
[0030] From the appendix Figure 3 and Figure 4 As shown, it is a structural schematic diagram of the height extension frame 3 in this embodiment. The height extension frame 3 also includes a connecting protrusion 34 and a fixing recess 35. The connecting protrusion 34 is installed on the upper surface of the extension rod A-type 31 and the extension rod B-type 32. There are four sets of connecting protrusions 34. The bottom ends of the extension rod A-type 31 and the extension rod B-type 32 are provided with fixing recesses 35 for insertion into the connecting protrusions 34.
[0031] When multiple sets of bearing plates 2 need to be installed or the height of the bearing plate 2 itself needs to be further adjusted during use, another set of separate extension rods A type 31 and B type 32 are selected. By connecting the protrusion 34 and fixing the recess 35, the connection between multiple sets of extension rods A type 31 and extension rods B type 32 is completed, extending the length of the original height extension frame 3, which facilitates the installation of multiple sets of bearing plates 2 or the movement of the bearing plate 2 to the target height.
[0032] From the appendix Figure 3 As shown, the base 1 has an installation groove on its surface for mounting the support plate 2, which facilitates the fit between the support plate 2 and the inner wall of the base 1 during use, ensuring the stability of the base 1 and the support plate 2 during use.
[0033] From the appendix Figure 5 As shown, it is a structural schematic diagram of the support plate 2 in this embodiment. The support plate 2 includes a main board 21 and an adapter block 22. The main board 21 is slidably installed in the mounting groove, and the adapter block 22 is symmetrically installed on both sides of the main board 21. The adapter block 22 is slidably connected to the motion groove 33.
[0034] During use, the attenuator or adapter is placed on the upper surface of the motherboard 21, and with the help of the adapter blocks 22 on both sides, the attenuator or adapter on the surface of the motherboard 21 is limited and calibrated to ensure the stability of the attenuator or adapter in subsequent use.
[0035] From the appendix Figure 5As shown, this is a structural schematic diagram of the support plate 2 in this embodiment. The support plate 2 also includes a fixing screw 23 and a fixing nut 24. The fixing screw 23 is installed on the side of the adapter block 22, and the fixing nut 24 is threaded on the outside of the fixing screw 23. In use, the fixing screw 23 is slid between the extension rod A type 31 and the extension rod B type 32. When the main board 21 moves to the target height, the fixing nut 24 is used to move along the thread on the outside of the fixing screw 23, pressing against the side walls of the extension rod A type 31 and the extension rod B type 32, thereby locking the position of the main board 21 itself.
[0036] From the appendix Figure 2 As shown, the height extension bracket 3 has a lifting slot inside that slides with the fixing screw 23. This allows the fixing screw 23 to flexibly adjust its height during use. The lifting slot can also limit the position of the fixing screw 23, ensuring the accuracy of the overall position of the motherboard 21 during installation.
[0037] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
