Abstract
Description
Technical Field
[0001] This utility model relates to a winding device, specifically a shock-resistant power filter, belonging to the field of power filter technology. Background Technology
[0002] Generally speaking, a power filter is a filter circuit composed of capacitors, inductors, and wire-wound resistors. The wire-wound resistors are made by winding nickel-chromium wire, manganese-copper wire, or constantan wire around a ceramic tube. The ceramic tubes are divided into cylindrical and annular structures. When winding the cylindrical structure, the wire will be evenly wound around the surface of the ceramic tube through the winding assembly to form a cylindrical structure. The tightness of the winding is closely related to the performance of the power filter.
[0003] Existing power filter resistor winding devices, such as the winding device and winding cart disclosed in CN210312903U, can effectively reduce the overall weight and volume of the device, and improve winding efficiency and quality while reducing the difficulty of use. However, this technical solution and current winding assemblies often require a guiding structure to guide the wire during winding. The guiding structure is generally linked by a screw, which requires a motor to continuously drive it to rotate. While the motor is rotating in both directions, there is a certain pause in the winding operation, which results in the overall winding resistor not being tight enough and easily producing gaps. The power filter will generate a certain amount of vibration during operation, and the vibration will cause the winding resistor to vibrate synchronously, thus leading to damage to the winding resistor. Utility Model Content
[0004] This utility model addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the purpose of this utility model is to overcome the aforementioned shortcomings in existing technologies by proposing a shock-resistant power filter.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A shock-resistant power filter includes a power filter housing, a capacitor, a resistor, an inductor, and a winding assembly. The capacitor, resistor, and inductor are all disposed inside the power filter housing, and wire is tightly wound on the resistor. The winding assembly is used to wind the wire on the resistor, and the winding assembly includes a frame, a transmission rod, and a guide module. The transmission rod is rotatably connected to the top side of the frame, and the guide module is disposed on the frame.
[0007] Furthermore, the guide module includes linkage components and limit components;
[0008] The linkage assembly includes a drive turntable, a linkage rod, a driven turntable, and a track. The linkage rod is rotatably connected to the other side of the top of the frame. The drive turntable and the driven turntable are respectively fixed to one end of the transmission rod and the linkage rod, and a resistor is snapped into the other end of the linkage rod. The track is connected between the drive turntable and the driven turntable.
[0009] The limit assembly is connected to the transmission rod.
[0010] Preferably, the limiting assembly includes a guide seat, a limiting slot, a sliding rod, a limiting sleeve, and a positioning pin;
[0011] The limiting slot is set on the transmission rod and has an X-shaped structure. A through hole is provided through the guide seat. The transmission rod is located in the through hole. The sliding rod is rotatably connected to the inner wall of the through hole of the guide seat and is locked in the limiting slot. Its height is greater than the depth of the limiting slot. The limiting sleeve is slidably nested on one end of the limiting sleeve and has a positioning hole provided through it. The positioning pin is slidably elastically connected to the slot on the transmission rod by a spring and is locked in the positioning hole.
[0012] Preferably, a guide rod is horizontally fixed on the frame, and the guide rod passes through a guide hole provided on the guide seat.
[0013] Preferably, the inner wall of the guide hole on the guide seat is provided with balls, and the balls are connected to the guide rod in a rolling manner.
[0014] Preferably, a throttle is provided at one end of the transmission rod.
[0015] Preferably, a support plate is fixed to the top of the guide seat, and a guide pulley is provided on the top of the support plate.
[0016] The beneficial effects of this utility model are as follows: the transmission rod rotates and drives the linkage rod synchronously through the track, which in turn drives the resistance ceramic tube connected to it to rotate, thereby causing the wire to be wound on its surface. At the same time as the transmission rod rotates, the sliding rod slides within the limiting slot, thereby driving the guide seat to move and guide the wire, so that it can be wound evenly and avoid accumulation. When it moves to one end of the limiting slot, under the influence of the X-shaped structure slot, the sliding rod rotates and changes its direction of movement, causing the guide seat to move in the opposite direction. The setting of the guide module makes the wire on the resistor more tightly wound during winding, thereby effectively preventing the winding resistor from vibrating and being damaged.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example 1, such as Figures 1 to 5 As shown, a shock-resistant power filter includes a power filter housing 101, a capacitor 102, a resistor 103, an inductor 104, and a winding assembly. The capacitor 102, resistor 103, and inductor 104 are all disposed inside the power filter housing 101, and wire is tightly wound on the resistor 103. The winding assembly is used to wind the wire on the resistor 103, and the winding assembly includes a frame 105, a transmission rod 2, and a guide module. The transmission rod 2 is rotatably connected to the top side of the frame 105, and the guide module is disposed on the frame 105.
[0025] Furthermore, the guide module includes linkage components and limit components;
[0026] The linkage assembly includes an active turntable 6, a linkage rod 7, a driven turntable 8, and a track 9. The linkage rod 7 is rotatably connected to the other side of the top of the frame 105. The active turntable 6 and the driven turntable 8 are respectively fixed to one end of the transmission rod 2 and the linkage rod 7, and a resistor 103 is snapped into the other end of the linkage rod 7. The track 9 is connected between the active turntable 6 and the driven turntable 8.
[0027] The limiting component is connected to the transmission rod 2;
[0028] The limiting assembly includes a guide seat 4, a limiting slot 12, a sliding rod 13, a limiting sleeve 14, and a positioning pin 15;
[0029] The limiting slot 12 is set on the transmission rod 2 and has an X-shaped structure. A through hole is provided through the guide seat 4. The transmission rod 2 is located in the through hole. The sliding rod 13 is rotatably connected to the inner wall of the through hole of the guide seat 4 and is limited and locked in the limiting slot 12. Its height is greater than the depth of the limiting slot 12. The limiting sleeve 14 is slidably nested and connected to one end of the limiting sleeve 14, and a positioning hole is provided through it. The positioning pin 15 is slidably elastically connected to the slot provided on the transmission rod 2 by a spring and is limited and locked in the positioning hole.
[0030] In this component, the transmission rod 2 rotates and drives the linkage rod 7 synchronously via the track 9. The rotation of the linkage rod 7 then drives the resistance ceramic tube connected to it to rotate, causing the wire to wind around its surface. Simultaneously, the sliding rod 13 slides within the limiting slot 12, thereby moving the guide seat 4 to guide the wire, ensuring even winding and preventing accumulation. When it moves to one end of the limiting slot 12, the sliding rod 13 rotates and changes its direction of movement under the influence of the X-shaped slot, causing the guide seat 4 to move in the opposite direction. The guide module ensures that the wire on the ceramic tube can be wound more tightly, effectively preventing vibration of the winding resistance and thus avoiding damage.
[0031] Example 2, as Figures 1 to 5 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:
[0032] A guide rod 3 is horizontally fixed on the frame 105. The guide rod 3 passes through the guide hole provided on the guide seat 4. The guide rod 3 limits the guide seat 4 and prevents the guide seat 4 from rotating during movement.
[0033] The inner wall of the guide hole on the guide seat 4 is provided with balls, and the balls are connected to the guide rod 3 in a rolling manner. The balls reduce the friction between the guide seat 4 and the guide rod 3, and prevent the guide seat 4 from being unable to move due to excessive friction.
[0034] A handle 5 is provided at one end of the transmission rod 2, which allows the operator to quickly drive the transmission rod 2 to rotate by using the handle 5.
[0035] A support plate 10 is fixed to the top of the guide seat 4, and a guide pulley 11 is provided on the top of the support plate 10 to guide the wound wire.
[0036] Working process: First, connect and lock the resistor 103 to the linkage rod 7; second, fix one end of the wire to the ceramic tube and position it in the slot on the guide pulley 11; then, drive the transmission rod 2 to rotate through the throttle 5, and drive the linkage rod 7 and the resistor ceramic tube connected to it to rotate through the track 9, so that the wire is wound on its surface, and while the transmission rod 2 rotates, the sliding rod 13 slides within the limiting slot 12, thereby driving the guide seat 4 to move and guide the wire; finally, when it moves to one end of the limiting slot 12, under the influence of the X-shaped structure slot, the sliding rod 13 rotates and changes its direction of movement, causing the guide seat 4 to move in the opposite direction until the resistor winding is completed.
[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
