Description

Technical Field

[0001] This utility model relates to the field of absorption limiter technology, and in particular to an absorption limiter. Background Technology

[0002] An absorptive limiter is a device used in the field of radio technology, primarily for limiting signal amplitude and protecting receivers from damage caused by high-power signals. Its basic structure includes a bridge circuit, a first limiting module, a second limiting module, a first load module, and a second load module. The input ports of the bridge circuit are the input ports of the absorptive limiter, and the isolation ports are the output ports. The coupled output port of the bridge circuit is connected to the input terminal of the first limiting module, and the through output port is connected to the input terminal of the second limiting module. The output terminal of the first limiting module is connected to the input terminal of the first load module, and the output terminal of the second limiting module is connected to the input terminal of the second load module. Both load modules are grounded.

[0003] Currently, when installing an absorber limiter, bolts are usually used to fix it directly through the mounting holes on the absorber limiter itself. This fixing method is very cumbersome. If the absorber limiter is damaged, multiple bolts need to be removed before it can be taken out for repair, which greatly reduces the repair efficiency. Therefore, we propose an absorber limiter. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Currently, when installing an absorber limiter, bolts are typically used to fix it directly through the mounting holes on the absorber limiter itself. This fixing method is very cumbersome. If the absorber limiter is damaged, multiple bolts need to be removed before it can be taken out for repair, which greatly reduces repair efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An absorptive limiter includes a mounting mechanism, wherein the limiter body is mounted on the top of the mounting mechanism;

[0007] The mounting mechanism includes a base, a bottom plate at the top of the base, a slot on the front of the base, a rod slidably connected inside the slot, the top of the rod being fixed to the front of the bottom plate, and an internal groove near the front and right side of the base, where a fixing component is installed.

[0008] As a preferred embodiment of this utility model, mounting holes are provided at the top of the base near the four corners.

[0009] The technical effect of adopting the above-mentioned further solution is that the base can be fixed to the outer casing with bolts through the mounting holes, preventing the base from loosening during use and improving the stability of use.

[0010] As a preferred embodiment of this utility model, a knob is rotatably connected to the right side of the base near the front and on the back of the fixing component, and the outer periphery of the knob protrudes towards the front to the right side of the fixing component with a protrusion.

[0011] The technical effect of adopting the above-mentioned further solution is that by rotating the knob, the protrusion part can be rotated to the right end of the slide rod, which can limit the slide rod and prevent it from disengaging from the inside of the groove, thereby improving the stability of use.

[0012] As a preferred embodiment of this utility model, an anti-slip pad is adhered to the top of the base plate.

[0013] The technical effect of adopting the above-mentioned further solution is that the anti-slip pad can increase the friction between the limiter body and the base plate, making the installation of the limiter body more stable.

[0014] As a preferred embodiment of this utility model, the inner wall of the slot is coated with a ceramic coating.

[0015] The technical effect of adopting the above-mentioned further solution is that the ceramic coating has excellent wear resistance, corrosion resistance and high temperature resistance, which can make the sliding between the slot and the plug smoother, thereby reducing friction and increasing the service life of the plug.

[0016] As a preferred embodiment of this utility model, the insertion rod is made of L-shaped metal, and a circular groove is formed on the left side of the insertion rod, extending through the right side.

[0017] As a preferred embodiment of this utility model, the fixing component includes a slide rod, which is slidably connected inside the built-in groove. One end of the slide rod near the left side passes through the slot and is slidably connected inside the circular groove. A fixing block is welded to the right side of the slide rod. Springs are symmetrically arranged on the left side of the fixing block near the top and bottom. The two ends of the springs are fixedly connected to the built-in groove and the fixing block, respectively.

[0018] The technical effect of adopting the above-mentioned further solution is that after the knob and the slide bar are disengaged, the slide bar can be pushed to the right by the spring, thereby disengaging the slide bar from the circular groove, which facilitates the disassembly of the limiter body.

[0019] As a preferred embodiment of this utility model, the slide bar is made of stainless steel with a smooth surface.

[0020] The technical effect of adopting the above-mentioned further solution is that stainless steel has high corrosion resistance, and the service life of the slide rod can be improved by using a stainless steel slide rod.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] In this invention, by designing the mounting mechanism and the limiter body, the knob is turned to disengage it from the sliding rod, and the spring pushes the sliding rod out of the groove, releasing the fixing of the insertion rod. Finally, the limiter body is pushed forward, and the base plate and insertion rod can be removed together for maintenance. Compared with the traditional fixing method, this greatly improves the convenience of operation and effectively improves maintenance efficiency. Attached Figure Description

[0032] Example 1:

[0033] like Figure 1-4 As shown, this utility model provides a technical solution: an absorption type limiter, including an installation mechanism 1, a limiter body 2 is installed at the top of the installation mechanism 1, the installation mechanism 1 includes a base 101, a base plate 102 is provided at the top of the base 101, a slot 103 is provided on the front of the base 101, a rod 104 is slidably connected inside the slot 103, the top of the rod 104 is fixed to the front of the base plate 102, and an internal groove 105 is provided inside the base 101 near the front and right side, and a fixing component 106 is installed inside the internal groove 105.

[0034] Example 2:

[0035] like Figure 1-4As shown, mounting holes 1011 are provided at the top of the base 101 near the four corners. Bolts can be used to fix the base 101 to the outer casing through the mounting holes 1011 to prevent loosening during use and improve stability. A knob 1012 is rotatably connected to the right side of the base 101 near the front and on the back of the fixing component 106. The outer periphery of the knob 1012 protrudes forward to the right side of the fixing component 106 and has a protrusion. By rotating the knob 1012, its protrusion rotates to the slide bar 1. At the right end of 061, the slide bar 1061 can be limited to prevent it from detaching from the circular groove 1041, thus improving stability. An anti-slip pad is adhered to the top of the base plate 102, which increases the friction between the limiter body 2 and the base plate 102, making the installation of the limiter body 2 more stable. The inner wall of the slot 103 is coated with a ceramic coating, which has excellent wear resistance, corrosion resistance, and high-temperature resistance, enabling smoother sliding between the slot 103 and the insertion rod 104, thereby reducing friction. The effect is to improve the service life of the insertion rod 104. The insertion rod 104 is made of L-shaped metal. A circular groove 1041 is opened from the left side to the right side of the insertion rod 104. The fixing component 106 includes a slide rod 1061, which is slidably connected inside the built-in groove 105. The end of the slide rod 1061 near the left side passes through the slot 103 and is slidably connected inside the circular groove 1041. A fixing block 1062 is welded to the right side of the outer periphery of the slide rod 1061. Springs 1063 are symmetrically arranged on the left side of the fixing block 1062 near the top and bottom. The two ends of the spring 1063 are fixedly connected to the built-in groove 105 and the fixing block 1062, respectively. After the knob 1012 disengages from the slide bar 1061, the spring 1063 can push the slide bar 1061 to the right, thereby disengaging the slide bar 1061 from the circular groove 1041, which facilitates the disassembly of the limiter body 2. The slide bar 1061 is made of smooth stainless steel, which has high corrosion resistance. The use of stainless steel for the slide bar 1061 can improve its service life.

[0036] The working process of this utility model is as follows: When disassembling and repairing an absorber-type limiter, first rotate the knob 1012 90° to disengage the part with the protrusion from the right end of the slide rod 1061. Under the action of the spring 1063, the fixing block 1062 will be pushed, causing the fixing block 1062 to slide the slide rod 1061 to the right, thereby pulling the left end of the slide rod 1061 out of the inside of the circular groove 1041, releasing the fixation of the insertion rod 104. Finally, push the limiter body 2 forward to pull the insertion rod 104 out of the slot 103. The base plate 102 and the insertion rod 104 can then be taken out together for repair. Compared with the traditional fixing method, this greatly improves the convenience of operation and effectively improves the repair efficiency.

[0037] 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.
