Description

Technical Field

[0001] This utility model relates to the field of notch filter technology, and in particular to a split-type notch filter. Background Technology

[0002] A notch filter is a specific type of filter mainly used to remove or greatly attenuate components of a specific frequency from a signal, that is, to eliminate the "notch" of a specific frequency. Notch filters have wide applications in fields such as communications, signal processing, and control engineering.

[0003] A split-type notch filter is a special type of notch filter design. Its main feature is that the notch filter tube and the grounding wire are manufactured separately and then combined together by a press-fitting process. Compared with the traditional one-piece notch filter that is made by turning part of the material on a rod to obtain the same shape, this design is easier to manufacture, makes it easier to control the dimensional accuracy of the grounding wire and the notch filter tube, and allows the use of different materials, thereby reducing production costs.

[0004] Currently, most common split-type notch filters are assembled using a crimping process. However, this assembly method has certain drawbacks. Because the crimping process makes disassembly difficult, if either the notch filter conductor or the grounding wire is damaged, the entire filter needs to be replaced, which undoubtedly increases the cost of use and makes it impractical. Therefore, we propose a split-type notch filter. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Currently, most common split-type notch filters are assembled using a crimping process. However, this assembly method has certain drawbacks. Because the crimping process makes disassembly difficult, if either the notch filter conductor or the grounding wire is damaged, the entire filter needs to be replaced, which undoubtedly increases the cost of use and makes it impractical.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A split-type notch filter includes a tube body, and a grounding wire is installed inside the tube body;

[0008] The pipe body has symmetrical mounting grooves on its left and right sides, and a side plate is slidably connected inside the mounting groove. A fixing ring is threadedly connected to the outer periphery of the pipe body near the bottom.

[0009] A reinforcing component is fitted around the periphery of the grounding conductor near the bottom.

[0010] As a preferred embodiment of this utility model, the tube body is a hollow barrel-shaped structure with an open top and a circular groove at the bottom, and the grounding wire is slidably connected inside the circular groove.

[0011] The technical advantage of adopting the above-mentioned further solution is that by sliding the grounding wire to the circular groove, the grounding wire can be quickly fixed to the bottom of the pipe body, improving the ease of use.

[0012] As a preferred embodiment of this utility model, the outer periphery of the tube body and the side plate are provided with threaded grooves near the bottom to facilitate the rotation of the fixing ring.

[0013] The technical effect of adopting the above-mentioned further solution is that the fixed ring can be rotated to the periphery of the pipe body and the side plate by opening the threaded groove, thereby fixing the side plate and preventing the side plate from detaching from the installation groove during use, thus improving the stability of use.

[0014] As a preferred embodiment of this utility model, limit strips are symmetrically welded to the front and back of the side plate, and the limit strips are slidably connected to the mounting groove.

[0015] The technical effect of adopting the above-mentioned further solution is that the sliding connection between the limiting strip and the mounting groove can limit the side plate during the up-and-down sliding, prevent it from shifting, make the installation process of the side plate more stable, and improve the ease of use.

[0016] As a preferred embodiment of this utility model, anti-slip stripes are engraved on the outer side of the side plate near the top.

[0017] The technical effect of adopting the above-mentioned further solution is that the anti-slip stripes make it easier to pull the side panel out of the mounting groove, thus improving the ease of use.

[0018] As a preferred embodiment of this utility model, the reinforcing component includes a nut, which is threadedly connected to the periphery of the grounding wire near the bottom, and a pressure plate is sleeved above the nut and located on the periphery of the grounding wire.

[0019] The technical effect of adopting the above-mentioned further solution is that the nut can be used to clamp and fix the grounding wire at the inner bottom of the pipe, making the connection between the grounding wire and the pipe more secure. The pressure plate can be used to press the nut to prevent it from loosening.

[0020] As a preferred embodiment of this utility model, the bottom of the nut has a frosted surface structure at the contact point with the bottom of the tube.

[0021] The technical effect of adopting the above-mentioned further solution is that the design of the frosted surface can increase the friction between the nut and the bottom of the tube, preventing the nut from loosening during use.

[0022] As a preferred embodiment of this utility model, the pressure plate has a circular structure, and its left and right sides extend outward and are inserted between the bottom of the mounting groove and the side plate.

[0023] The technical effect of adopting the above-mentioned further solution is that the extension of the left and right sides of the pressure plate can fix the pressure plate with the mounting groove, preventing it from sliding up and down during use.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] In this invention, by designing the pipe body and grounding wire, when removing the grounding wire from the pipe body, the fixing ring is rotated to disengage it from the side plate, the side plate is pulled out from the mounting groove, and the pressure plate is slid upwards to slide out from the outside of the grounding wire. Then, the nut is rotated with a tool to remove it from the outside of the grounding wire, and finally the grounding wire is pulled out from the circular groove, thus completing the removal of the grounding wire from the pipe body. Compared with the traditional riveting process, there is no need to replace the whole thing, which greatly improves practicality and effectively reduces the cost of use. Attached Figure Description

[0035] Example 1:

[0036] like Figure 1-4 As shown, this utility model provides a technical solution: a split-type notch filter, including a tube body 1, a grounding wire 2 installed inside the tube body 1, mounting grooves 101 symmetrically opened on the left and right sides of the tube body 1, a side plate 102 slidably connected inside the mounting groove 101, a fixing ring 103 threadedly connected to the outer periphery of the tube body 1 near the bottom, and a reinforcing component 201 sleeved on the outer periphery of the grounding wire 2 near the bottom.

[0037] Example 2:

[0038] like Figure 1-4As shown, the tube body 1 is a hollow barrel-shaped structure with an open top and a circular groove 104 at the bottom. The grounding wire 2 is slidably connected inside the circular groove 104. Through the sliding connection between the grounding wire 2 and the circular groove 104, the grounding wire 2 can be quickly fixed to the bottom of the tube body 1, improving ease of use. The outer periphery of both the tube body 1 and the side plate 102 near the bottom has threaded grooves for rotating the fixing ring 103. These threaded grooves allow the fixing ring 103 to be rotated to the outer periphery of the tube body 1 and the side plate 102, thereby fixing the side plate 102 and preventing... To prevent the side plate 102 from detaching from the mounting groove 101 during use and improve stability, limit strips 1021 are symmetrically welded to the front and back of the side plate 102. These limit strips 1021 are slidably connected to the mounting groove 101, thus limiting the side plate 102 during vertical sliding and preventing it from shifting. This makes the installation process of the side plate 102 more stable and improves ease of use. Anti-slip stripes 1022 are engraved on the outer side of the side plate 102 near the top. 1022 facilitates the removal of the side plate 102 from the mounting slot 101, improving ease of use. The reinforcing component 201 includes a nut 2011, which is threaded onto the outer periphery of the grounding wire 2 near the bottom. A pressure plate 2012 is fitted above the nut 2011 and around the grounding wire 2. The nut 2011, in conjunction with the inner bottom of the tube body 1, clamps and fixes the grounding wire 2, making the connection between the grounding wire 2 and the tube body 1 more secure. The pressure plate 2012 can press down on the nut 2011 to prevent... If it becomes loose, the bottom of the nut 2011 has a frosted surface at the contact point with the bottom of the tube 1. The frosted surface design can increase the friction between the nut 2011 and the bottom of the tube 1, preventing the nut 2011 from becoming loose during use. The pressure plate 2012 has a circular structure, and its left and right sides extend outward and are inserted between the bottom of the mounting groove 101 and the side plate 102. The extension of the pressure plate 2012 on the left and right sides can allow the side plate 102 to cooperate with the mounting groove 101 to fix the pressure plate 2012 and prevent it from sliding up and down during use.

[0039] The working process of this utility model is as follows: When disassembling and using a split-type notch filter, firstly rotate the fixing ring 103 to make it spiral downwards and detach from the periphery of the side plate 102. Pull the side plate 102 upwards to separate it from the mounting groove 101. Then push the pressure plate 2012 upwards and remove it from the periphery of the grounding wire 2. Use a tool to rotate the nut 2011 to make it spiral upwards on the periphery of the grounding wire 2 and separate the nut 2011 from the grounding wire 2. Finally, pull the grounding wire 2 out from the inside of the circular groove 104 to complete the entire disassembly process. Compared with the traditional riveting process, when either the tube body 1 or the grounding wire 2 is damaged, there is no need to replace the whole thing, which greatly improves practicality and effectively reduces the cost of use.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
