Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of antenna coils that are resistant to breakage, specifically an antenna coil that is resistant to breakage. Background Technology
[0002] Two sets of unconnected coils wound around a ferrite rod constitute the antenna coil used in the device's input circuit. Coils can be classified as circular or flat coils depending on the shape of the ferrite rod. Ferrite rods are made of manganese-zinc ferrite and nickel-zinc ferrite materials. Manganese-zinc ferrite rods can only be used to receive medium-wave signals, while nickel-zinc ferrite rods are suitable for receiving short-wave signals. The two types of ferrite rods cannot interact with each other.
[0003] In use, the antenna coil has insufficient anti-breakage effect, which can easily lead to the breakage of the antenna coil. Therefore, it is necessary to protect the antenna coil from breakage. Hence, a breakage-resistant antenna coil is proposed to solve the above-mentioned problems. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a break-resistant antenna coil in response to the shortcomings of the prior art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a breakage-resistant antenna coil, including a protective frame, a coil roller disposed inside the protective frame, a lead-out frame fixedly connected to the side of the protective frame, a horizontal plate fixedly connected to the top of the protective frame, an opening and closing mechanism fixedly connected to the top of the horizontal plate, and a limiting mechanism fixedly connected inside the lead-out frame. The opening and closing mechanism includes a sliding groove, a slider, a first locking block, a rotating rod, a second locking block, and a fixing plate. The sliding groove is fixedly connected to the top of the horizontal plate, the slider is slidably connected inside the sliding groove, the first locking block is fixedly connected to the side of the slider, the fixing plate is fixedly connected to the side of the protective frame, the rotating rod is rotatably connected to the side of the protective frame, and the second locking block is fixedly connected to the rotating rod. The second locking block is installed to lock and limit the first locking block.
[0006] Preferably, a first spring is fixedly connected inside the slide groove, and the other end of the first spring is fixedly connected to the side of the slider. A cover plate is fixedly connected to the side of the slider. The first spring is installed to limit the sliding of the slider and provide contraction force.
[0007] Preferably, a second spring is fixedly connected to the top of the fixing plate, and the other end of the second spring is fixedly connected to the bottom of the second locking block. The second spring is installed to provide limiting support for the second locking block.
[0008] Preferably, the limiting mechanism includes a slot, which is opened inside the wire frame, and a plug rod is threaded into the slot.
[0009] Preferably, a handle is fixedly connected to the top of the insertion rod, a third spring is fixedly connected to the bottom of the insertion rod, and a limit block is fixedly connected to the other end of the third spring. The third spring is installed to elastically limit the limit block and prevent excessive force from damaging the antenna.
[0010] Preferably, the protective frame has two ventilation slots inside, located on the front and rear sides of the protective frame. These ventilation slots are used to ventilate the interior of the protective frame and prevent excessive moisture from hindering ventilation.
[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects:
[0012] 1. The antenna coil designed to prevent breakage uses a sliding groove, a slider, a first spring, a first locking block, a rotating rod, a second locking block, a fixing plate, and a second spring to cooperate. The opening and closing of the cover is achieved through the cooperation between the first locking block and the second locking block, making it easy to take out the coil. Furthermore, the protective frame protects the coil from breakage by preventing it from being broken due to external forces.
[0013] 2. This type of anti-breakage antenna coil, through the cooperation between the slot, the plug rod, the handle, the third spring, and the limiting block, can limit one end of the antenna by the limiting block at the bottom of the third spring, so as to avoid the antenna end from being severely rubbed against the inner wall of the wire frame and thus causing damage to the antenna outer skin.

[0023] Please see Figure 1-4One embodiment of this utility model is: a breakage-resistant antenna coil, including a protective frame 1, a coil roller 7 disposed inside the protective frame 1, a lead-out frame 2 fixedly connected to the side of the protective frame 1, a horizontal plate 3 fixedly connected to the top of the protective frame 1, an opening and closing mechanism 4 fixedly connected to the top of the horizontal plate 3, a limit mechanism 5 fixedly connected inside the lead-out frame 2, the opening and closing mechanism 4 including a slide groove 411, a slider 412, a first locking block 414, a rotating rod 415, a second locking block 416, and a fixing plate 417, the slide groove 411 fixedly connected to the top of the horizontal plate 3, the slider 412 slidably connected inside the slide groove 411, the installation of the slide groove 411 facilitates the sliding of the slider 412, the first locking block 414 is fixedly connected to the side of the slider 412, and the fixing plate 417 is fixedly connected to the side of the slider 412. A first spring 413 is fixedly connected to the side of the protective frame 1, and the other end of the first spring 413 is fixedly connected to the side of the slider 412. A cover plate 419 is fixedly connected to the side of the slider 412. The first spring 413 is installed to limit the sliding of the slider 412 and provide contraction force. A second spring 418 is fixedly connected to the top of the fixed plate 417. The other end of the second spring 418 is fixedly connected to the bottom of the second block 416. The second spring 418 is installed to limit and support the second block 416.
[0024] Working principle: The antenna coil is placed on the coil roller 7 inside the protective frame 1. The second locking block 416 is pulled down, which drives the rotating rod 415 to rotate. When the second locking block 416 moves downward, it compresses the second spring 418. Then the cover plate 419 is moved, and the cover plate 419 drives the slider 412 to slide on the slide groove 411. When the slider 412 moves, it drives the first spring 413 to stretch. When the slider 412 drives the first locking block 414 to the top of the second locking block 416, the second locking block 416 is released. Under the elastic force of the second spring 418, the second locking block 416 moves upward. In this way, the first locking block 414 limits the second locking block 416, realizing the convenient opening and closing of the cover plate 419, which makes it easy to take out the antenna coil inside the protective frame 1.
[0025] Please see Figure 1-4Based on the above embodiments, in another embodiment of this utility model, the limiting mechanism 5 includes a slot 511, which is opened inside the cable outlet frame 2. A rod 512 is threadedly connected inside the slot 511. The slot 511 facilitates the sliding connection of the rod 512 inside the slot 511. A handle 513 is fixedly connected to the top of the rod 512. The handle 513 is installed to facilitate the rotation of the rod 512. A third spring 514 is fixedly connected to the bottom of the rod 512. A limiting block 515 is fixedly connected to the other end of the third spring 514. The third spring 514 is installed to elastically limit the limiting block 515 to prevent excessive force from damaging the antenna. A ventilation slot 6 is opened inside the protective frame 1. There are two ventilation slots 6, which are opened on the front and rear sides of the protective frame 1. The ventilation slots 6 are used to ventilate the inside of the protective frame 1 to prevent excessive moisture inside from hindering ventilation.
[0026] Working principle: By rotating the handle 513, the handle 513 drives the insertion rod 512 to rotate. The insertion rod 512 rotates inside the slot 511. The insertion rod 512 rotates downward, driving the third spring 514 at the bottom of the insertion rod 512 to move downward. The third spring 514 drives the bottom limiting block 515 to move downward. The limiting blocks 515 on the upper and lower sides limit the antenna, preventing one end of the antenna from rubbing violently against the inner wall of the wire frame 2, which would damage the outer skin of the antenna.
[0027] This utility model provides a breakage-resistant antenna coil. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
