Description

Technical Field

[0001] This utility model relates to the field of magnetic ring fixing technology, and in particular to a fixing device for magnetic rings. Background Technology

[0002] With the development of electronic technology, especially the trend of miniaturization, integration and high performance of electronic devices, the requirements for electromagnetic compatibility inside electronic devices are getting higher and higher. The performance and stability of magnetic rings have a huge impact on the normal operation of the entire device.

[0003] When faced with magnetic rings of different sizes or shapes, traditional fixing devices may not be convenient for automatically adjusting the fixing force and method, requiring manual intervention, which increases the complexity and uncertainty of operation and has low adaptability. In addition, existing devices may use simple rubber pads or springs for buffering, which have limited buffering effect and poor protection effect in complex vibration environments or large impact forces, reducing the service life of the device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fixing device for magnetic rings.

[0005] This utility model is achieved using the following technical solution: a fixing device for a magnetic ring, comprising a housing, a sliding shell slidably connected inside the housing, a top plate fixedly connected to the top of the housing, and further comprising:

[0006] The fixing mechanism includes a sliding block fixedly connected inside the top plate, a limiting block slidably connected inside the sliding block, and a protective sleeve provided on the top of the limiting block;

[0007] A buffer mechanism, comprising a limiting rod fixedly connected to the inner wall of the housing, wherein a spring is provided on the outside of the limiting rod.

[0008] As a further improvement to the above solution, a servo motor is fixedly connected to the bottom inner wall of the housing, a threaded rod is fixedly connected to the output end of the servo motor, a moving block is threadedly connected to the outside of the threaded rod, and a first connecting rod is rotatably connected to the inside of the moving block.

[0009] Through the above technical solution, the servo motor provides a power source for fixing the magnetic ring, and the power is transmitted by the threaded rod, the moving block and the first connecting rod.

[0010] As a further improvement to the above solution, a first rotating block is fixedly connected to the bottom of the limiting block, a fixing rod is fixedly connected to the top of the limiting block, and a protective sleeve is fixedly connected to the outside of the fixing rod.

[0011] The above technical solution allows the first rotating block, the limiting block, and the fixing rod to move the protective sleeve, thereby fixing the magnetic ring.

[0012] As a further improvement to the above solution, the threaded rod is rotatably connected to the bottom of the sliding block, the first connecting rod is rotatably connected between the first rotating block and the moving block, and the first rotating block is slidably connected inside the sliding block.

[0013] Through the above technical solution, the first link ensures the rationality and stability of the connection and movement between various components, so that the power transmission starting from the servo motor can accurately and stably drive the protective sleeve to fix the magnetic ring.

[0014] As a further improvement to the above solution, a second rotating sleeve is fixedly connected to the bottom of the sliding shell, a second connecting rod is rotatably connected inside the second rotating sleeve, a sliding sleeve is slidably connected to the outside of the limiting rod, and a fixed sleeve is fixedly connected to the end of the limiting rod away from the outer shell.

[0015] As a further improvement to the above solution, a spring is fixedly connected to the outside of the fixed sleeve, a support plate is fixedly connected to the outside of the fixed sleeve, and a damper is fixedly connected to the top of the support plate.

[0016] The above technical solution involves connecting a spring and a support plate to the outside of the fixed sleeve, with a damper connected to the top of the support plate. This allows the force to be transmitted to the spring and damper during vibration and impact, providing a key structural foundation for reducing vibration amplitude and absorbing vibration.

[0017] As a further improvement to the above solution, the spring is fixedly connected between the sliding sleeve and the fixed sleeve, the damper is fixedly connected to the bottom of the sliding shell, and the second connecting rod is rotatably connected between the second rotating sleeve and the sliding sleeve.

[0018] The above technical solution clarifies the connection relationship between the components during the buffering process, ensuring the effective transmission of force during vibration and impact, thereby achieving the functions of reducing vibration and protecting the magnetic ring and the device.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention uses a servo motor to drive a threaded rod to rotate, which in turn causes the first connecting rod to slide the first rotating block. This causes the first rotating block to move the limiting block, which in turn moves the fixing rod. Finally, the protective sleeve moves outward to contact the magnetic ring, thus fixing the magnetic ring. This ensures that the magnetic ring is in a stable position within the device, preventing it from moving arbitrarily during subsequent operations, testing, or use. It can also accommodate magnetic rings of various sizes, improving the adaptability of the device.

[0021] This invention transmits force to the top plate and then to the sliding shell via a sliding block. The sliding shell drives the second rotating sleeve at the bottom to move, ultimately causing the sliding sleeve to slide and compress the spring on the limiting rod. At the same time, the sliding shell transmits force to the damper. A series of structures transmit force to the spring and the damper, thereby reducing the vibration amplitude, absorbing vibration, reducing the impact of vibration on the device, making the fixation more stable, protecting the magnetic ring from damage by vibration impact, and extending the service life of the device and the magnetic ring.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5 A magnetic ring fixing device according to this embodiment includes a housing 1, a sliding shell 11 slidably connected inside the housing 1, and a top plate 12 fixedly connected to the top of the housing 1. It also includes:

[0032] The fixing mechanism 2 includes a sliding block 209 fixedly connected inside the top plate 12. A limit block 206 is slidably connected inside the sliding block 209. A protective sleeve 208 is provided on the top of the limit block 206.

[0033] The buffer mechanism 3 includes a limiting rod 304 fixedly connected to the inner wall of the outer shell 1, and a spring 306 is provided on the outside of the limiting rod 304.

[0034] A servo motor 201 is fixedly connected to the bottom inner wall of the outer casing 1. A threaded rod 202 is fixedly connected to the output end of the servo motor 201. A moving block 203 is threadedly connected to the outside of the threaded rod 202. A first connecting rod 204 is rotatably connected inside the moving block 203.

[0035] The bottom of the limiting block 206 is fixedly connected to a first rotating block 205, the top of the limiting block 206 is fixedly connected to a fixing rod 207, and the outside of the fixing rod 207 is fixedly connected to a protective sleeve 208.

[0036] The threaded rod 202 is rotatably connected to the bottom of the sliding block 209, the first connecting rod 204 is rotatably connected between the first rotating block 205 and the moving block 203, and the first rotating block 205 is slidably connected inside the sliding block 209.

[0037] The bottom of the sliding shell 11 is fixedly connected to a second rotating sleeve 301. The inside of the second rotating sleeve 301 is rotatably connected to a second connecting rod 302. The outside of the limiting rod 304 is slidably connected to a sliding sleeve 303. The end of the limiting rod 304 away from the outer shell 1 is fixedly connected to a fixing sleeve 305.

[0038] A spring 306 is fixedly connected to the outside of the fixed sleeve 305, a support plate 307 is fixedly connected to the outside of the fixed sleeve 305, and a damper 308 is fixedly connected to the top of the support plate 307.

[0039] Spring 306 is fixedly connected between sliding sleeve 303 and fixed sleeve 305, damper 308 is fixedly connected to the bottom of sliding shell 11, and second connecting rod 302 is rotatably connected between second rotating sleeve 301 and sliding sleeve 303.

[0040] The implementation principle of a magnetic ring fixing device in this embodiment is as follows: Before use, the device is placed in a suitable position. At this time, the magnetic ring can be placed on the top of the sliding block 209. Then, the servo motor 201 can be started to drive the threaded rod 202 to rotate clockwise at the bottom of the sliding block 209. Since the moving block 203 is threaded to the outside of the threaded rod 202, when the threaded rod 202 rotates clockwise, the moving block 203 moves upward and drives the first connecting rod 204 to rotate. The first connecting rod 204 drives the first rotating block 205 to slide inside the sliding block 209, thereby causing the first rotating block 205 to drive the limiting block 206 to move. Then, the limiting block 206 drives the fixing rod 207 to move, and finally drives the protective sleeve 208 to move outward and contact the magnetic ring to fix the magnetic ring.

[0041] After being fixed, if vibration or impact occurs, the sliding block 209 will transmit the force received to the sliding shell 11 through the top plate 12, causing the sliding shell 11 to slide inside the outer shell 1. This will drive the second rotating sleeve 301 at the bottom of the sliding shell 11 to move, causing the second rotating sleeve 301 to drive the second connecting rod 302 to move, thereby causing the sliding sleeve 303 to slide on the limiting rod 304 and compress the spring 306, so that the force is transmitted to the spring 306, thereby reducing the vibration amplitude. At the same time, the sliding shell 11 will transmit the force to the damper 308 to absorb the vibration, reduce the impact of vibration on the device, and make the fixation more stable.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
