Description

Technical Field

[0001] This invention relates to the field of filter technology, and in particular to a device for fixing internal coils in a filter. Background Technology

[0002] A filter is a frequency-selective device that allows specific frequency components of a signal to pass through while significantly attenuating other frequency components. This frequency selection property of filters can be used to filter out interference noise or perform spectrum analysis. In other words, any device or system that allows specific frequency components of a signal to pass through while significantly attenuating or suppressing other frequency components is called a filter. A filter is a device that filters waves. "Wave" is a very broad physical concept; in the field of electronics, "wave" is narrowly defined to specifically refer to the process describing the fluctuations in the values ​​of various physical quantities over time. This process, through the action of various sensors, is converted into a time function of voltage or current, called the time waveform of various physical quantities, or simply a signal. Because the independent variable time takes continuous values, it is called a continuous-time signal, also commonly referred to as an analog signal. A filter is a filtering circuit composed of capacitors, inductors, and resistors. Filters can effectively filter out specific frequency points or frequencies other than those in a power supply line, obtaining a power signal of a specific frequency, or eliminating a power signal with a specific frequency. However, in the production and processing of filters in the prior art, it is inconvenient to fix the internal coils after winding, which makes the coils prone to scattering after winding. This not only reduces work efficiency but also causes inconvenience to users and fails to meet people's actual production and processing needs for filters. Summary of the Invention

A central partition is provided between the two upright plates, and a winding roller is provided between the central partition and the adjacent upright plate. Through holes are provided on the central partition and on the two upright plates at positions corresponding to the ends of the winding rollers. A long threaded rod is inserted into the cavity of the through hole on the central partition, and the two ends of the long threaded rod pass through corresponding through holes on the two upright plates.

[0007] Furthermore, the extraction slot on the upright plate is connected to the C-shaped movable slot, and the extraction slot is located above the C-shaped movable slot.

[0008] Furthermore, the limiting component includes a strip-shaped base, with a transverse threaded rod that matches the C-shaped movable groove fixedly connected to the end of the strip-shaped base.

[0009] Furthermore, the outer diameter of the transverse threaded rod is consistent with the width of the extraction slot, and the transverse threaded rod is movably inserted into the corresponding extraction slot.

[0010] Furthermore, an anti-slip washer is fixedly connected to the side of the annular pressure plate near the corresponding upright plate, and the anti-slip washer is in contact with the outer wall of the upright plate.

[0011] Furthermore, the pressing mechanism includes a U-shaped frame adapted to the strip base. A circular slot is formed through the top surface of the U-shaped frame, and a matching vertical threaded rod is inserted into the circular slot. A sleeve is fitted around the outer periphery of the top end of the vertical threaded rod, and the inner wall of the sleeve has a threaded groove that cooperates with the vertical threaded rod. The sleeve and the vertical threaded rod are connected by a thread. A fixing rod is provided at the bottom end of the vertical threaded rod, and a fixed rod is connected to the bottom end of the fixing rod. The bottom end of the fixing rod is also connected to a telescopic spring adapted to the positioning protrusion. An outer movable cylinder is movably sleeved on the outer periphery of the bottom end of the fixing rod. A top pressing block is fixedly connected to the bottom end of the outer movable cylinder. Multiple limiting sliders are evenly connected to the outer periphery of the bottom end of the fixing rod. A vertical limiting groove is vertically opened on the side wall of the inner cavity of the outer movable cylinder at a position corresponding to each limiting slider, and each limiting slider is movably set in its corresponding vertical limiting groove.

[0012] Furthermore, one end of the telescopic spring is sleeved on the outer periphery of the positioning protrusion, and this end of the telescopic spring is fixedly connected to the bottom end of the fixed rod.

It not only allows people to quickly fix the wound coil inside the filter, effectively preventing the wound coil from becoming tangled, but also improves work efficiency, makes it convenient for people to use, and meets people's actual production and processing needs for filters.

[0017] When fixing the wound coil, the horizontal threaded rod moves in the C-shaped movable groove, allowing it to adjust the orientation of the pressure block. After the pressure block is adjusted, the vertical threaded rod moves it horizontally to the end of the copper wire. Once the pressure block is horizontally adjusted, the sleeve on the vertical threaded rod is tightened to fix its position. This allows the pressure block to be precisely adjusted to the desired end of the copper wire. Then, under the action of the telescopic spring, the outer movable cylinder moves the pressure block and presses down on the end of the copper wire, thus quickly fixing the wound coil and effectively preventing it from becoming tangled, making it convenient for users.

The sleeve 12 and the vertical threaded rod 11 are connected by a thread. A fixing rod 8 is provided at the bottom end of the vertical threaded rod 11, and a positioning protrusion 21 is connected to the bottom end of the fixing rod 8.

[0041] The specific working principle and usage method of this invention are as follows:

[0042] This invention provides a device for fixing internal coils in a filter. In use, the copper wire to be fixed is wound around the outer circumference of a take-up roller 3. After the copper wire is wound, the transverse threaded rod 15 moves in a C-shaped movable groove, allowing it to adjust the orientation of the pressure block 10. Once the orientation of the pressure block 10 is adjusted, the nut B18 on the transverse threaded rod 15 is tightened. Then, the vertical threaded rod 11 drives the pressure block 10 to move laterally, allowing it to move again towards the copper wire. At the end, after the top pressure block 10 has been adjusted laterally, the sleeve 12 on the vertical threaded rod 11 is tightened to fix the position of the top pressure block 10. This allows the top pressure block 10 to be precisely adjusted to the desired end of the copper wire. Subsequently, under the action of the telescopic spring 22, the outer movable cylinder 9 drives the top pressure block 10 to move and press and fix the end of the copper wire, thereby achieving rapid fixation of the wound coil and effectively preventing the wound coil from becoming tangled, making it convenient for users. When the outer movable cylinder 9 moves vertically, the vertical limiting groove limits the movement of the limiting slider 20, ensuring that the outer movable cylinder 9 will not detach from the fixing rod 8 during vertical movement. When the take-up roller 3 needs to be disassembled for replacement or repair, first unscrew the two nuts A5 on one end of the long threaded rod 4, and then pull the long threaded rod 4 out from inside the two take-up rollers 3. This allows the take-up roller 3 to be quickly removed from between the vertical plate 1 and the middle partition 2, making it convenient for workers to replace or repair the take-up roller 3.
