Description

Technical Field

[0001] This utility model relates to the field of brushless fan lead wire technology, and in particular to a brushless fan lead wire structure. Background Technology

[0002] In modern industry and daily life, brushless fans are widely used in ventilation, heat dissipation, air purification, equipment cooling and other fields due to their advantages such as high efficiency, energy saving, long life and convenient maintenance. The lead wire of the brushless fan is an important component that connects the fan to the external power supply and control system. The rationality of its structural design directly affects the performance and reliability of the fan.

[0003] Existing brushless fan lead wire structures typically use simple perforations to lead the wires out, lacking effective sealing and securing measures. During long-term use, dust, moisture, and other impurities can easily enter the fan through the gap between the lead wire and the perforation, leading to problems such as aging of the lead wire insulation and short circuits. This severely affects the normal operation of the fan and shortens its service life. Therefore, to solve this problem, we propose a new brushless fan lead wire structure. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a brushless fan lead wire structure that can tightly wrap the lead wire, prevent dust, moisture and other impurities from entering the take-up box, ensure good sealing performance and extend the service life of the lead wire, and improve the stability of the brushless fan operation. At the same time, the limiting sleeve, through the cooperation of the limiting plate and the limiting groove, moves only in a straight line along the axial direction within the positioning sleeve, ensuring that the lead wire will not deviate during the clamping process, making the clamping operation more precise and efficient.

[0005] This utility model also provides a brushless fan lead wire structure as described above, including a body, a take-up box fixedly installed on one side of the body, a wire through hole opened on one side of the take-up box, a fixing sleeve threadedly connected inside the wire through hole on one side of the take-up box, a sealing ring fixedly installed at one end of the fixing sleeve, a support plate fixedly installed inside the take-up box, a compression sleeve fixedly installed on one side of the support plate, a sealing sleeve fixedly installed inside the compression sleeve, a fixing plate fixedly installed on one side of the body, a positioning sleeve fixedly installed inside the fixing plate, a limit sleeve movably installed inside the positioning sleeve, mounting grooves opened on both sides of the limit sleeve, a fixing ring fixedly installed inside the mounting groove, a positioning shaft movably installed inside the fixing ring, a limit ring fixedly installed outside the positioning shaft, a spring fixedly installed below the limit ring, and a clamping plate fixedly installed below the positioning shaft.

[0006] According to the brushless fan lead wire structure of this utility model, the fixed sleeve has a first external thread on its outer side and an internal thread on its inner side.

[0007] According to the brushless fan lead wire structure of this utility model, the extrusion sleeve has a second external thread on its outside and multiple through grooves on its inside.

[0008] According to the brushless fan lead wire structure of this utility model, the spring is disposed outside the positioning shaft, and one end of the spring is fixedly connected to the fixing ring.

[0009] According to the present invention, a brushless fan lead wire structure is provided, wherein a limiting plate is fixedly installed on both sides of the inside of the positioning sleeve, a limiting groove is provided inside the limiting sleeve, and one end of the limiting plate extends into the inside of the limiting groove.

[0010] According to the brushless fan lead wire structure of this utility model, the limiting sleeve can only move linearly along the axial direction within the positioning sleeve through the cooperation of the limiting plate and the limiting groove.

[0011] According to the brushless fan lead wire structure of this utility model, the extrusion sleeve is threadedly connected to the fixed sleeve, and the through groove of the extrusion sleeve will undergo elastic deformation.

[0012] According to the brushless fan lead wire structure of this utility model, the outer diameter of the limiting ring is larger than the inner diameter of the fixed ring, and it prevents the positioning shaft from coming out of the fixed ring.

[0013] Beneficial effects:

[0014] 1. The brushless fan lead wire structure of this technical solution features a first external thread on the outside of the fixing sleeve that facilitates connection with the wire through hole thread of the take-up box, achieving a stable installation. The internal internal thread can mate with the second external thread of the compression sleeve. By rotating the compression sleeve, the internal groove undergoes elastic deformation. Combined with the sealing sleeve, it can tightly wrap the lead wire, preventing dust, moisture, and other impurities from entering the take-up box, ensuring good sealing performance, extending the service life of the lead wire, and improving the stability of the brushless fan operation.

[0015] 2. The clamping structure, consisting of a limiting sleeve, a fixing ring, a positioning shaft, a spring, and a clamping plate, utilizes the elastic force of the spring to apply pressure to the lead wire, achieving adaptive clamping for lead wires of different thicknesses. When the lead wire thickness changes, the positioning shaft can move within the fixing ring, and the spring can compress or extend to adjust the position and pressure of the clamping plate, ensuring stable and reliable fixation of the lead wire. At the same time, the limiting sleeve, through the cooperation of the limiting plate and the limiting groove, moves only linearly along the axial direction within the positioning sleeve, ensuring that the lead wire will not deviate during clamping, making the clamping operation more precise and efficient.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-5This utility model discloses a brushless fan lead wire structure, comprising a body 1 for easy fixing and collection of the lead wire. A take-up box 2 is fixedly installed on one side of the body 1 for easy collection of the lead wire. A wire through hole is opened on one side of the take-up box 2, and a fixing sleeve 3 is threadedly connected inside the wire through hole on one side of the take-up box 2. The fixing sleeve 3 can compress a compression sleeve 6. A sealing ring 4 is fixedly installed at one end of the fixing sleeve 3 for sealing. A support plate 5 is fixedly installed inside the take-up box 2 for supporting the compression sleeve 6. The compression sleeve 6 is fixedly installed on one side of the support plate 5 for compressing a sealing sleeve 7. The sealing sleeve 7 is fixedly installed inside the compression sleeve 6 for tightly wrapping the lead wire. A fixing plate 8 is fixedly installed on one side of the body 1 for easy installation of a positioning sleeve. 9. A positioning sleeve 9 is fixedly installed inside the fixing plate 8. The positioning sleeve 9 facilitates the movement of the limiting sleeve 10. The limiting sleeve 10 is movably fitted inside the positioning sleeve 9. The limiting sleeve 10 facilitates the fixing of the lead wire. The limiting sleeve 10 has mounting grooves 11 on both sides inside. The mounting grooves 11 facilitate the operation of the positioning shaft 13. A fixing ring 12 is fixedly installed inside the mounting groove 11. The fixing ring 12 limits the positioning shaft 13. The positioning shaft 13 is movably fitted inside the fixing ring 12. The positioning shaft 13 allows the clamping plate 16 to move. A limiting ring 14 is fixedly installed outside the positioning shaft 13. The limiting ring 14 prevents the positioning shaft 13 from moving excessively. A spring 15 is fixedly installed below the limiting ring 14. The elastic effect of the spring 15 allows the positioning shaft 13 to return to its original position. A clamping plate 16 is fixedly installed below the positioning shaft 13. The clamping plate 16 fixes the lead wire.

[0026] Specifically, the fixed sleeve 3 has a first external thread 17 on its outside and an internal thread on its inside. The internal thread of the fixed sleeve 3 facilitates compression, which in turn compresses the sleeve 6.

[0027] Specifically, the extrusion sleeve 6 has a second external thread 18 on its outside and multiple through grooves on its inside, through which the extrusion sleeve 6 can undergo elastic deformation.

[0028] Specifically, the spring 15 is located outside the positioning shaft 13, and one end of the spring 15 is fixedly connected to the fixing ring 12. The elastic effect of the spring 15 can drive the positioning shaft 13 to move.

[0029] Specifically, a limiting plate 19 is fixedly installed on both sides of the inside of the positioning sleeve 9, and a limiting groove 20 is opened inside the limiting sleeve 10. One end of the limiting plate 19 extends into the inside of the limiting groove 20. When the limiting plate 19 moves inside the limiting groove 20, the limiting groove 20 can limit the limiting plate 19.

[0030] Specifically, the limiting sleeve 10, through the cooperation of the limiting plate 19 and the limiting groove 20, can only move linearly along the axial direction within the positioning sleeve 9. When it can only move linearly along the axial direction within the positioning sleeve 9, it can prevent the limiting sleeve 10 from deviating from the movement trajectory.

[0031] Specifically, the extrusion sleeve 6 is threadedly connected to the fixed sleeve 3. The through groove of the extrusion sleeve 6 will undergo elastic deformation. When the extrusion sleeve 6 undergoes elastic deformation, it can compress the sealing sleeve 7 to seal.

[0032] Specifically, the outer diameter of the limiting ring 14 is larger than the inner diameter of the fixing ring 12, and it prevents the positioning shaft 13 from coming out of the fixing ring 12. Preventing the positioning shaft 13 from coming out of the fixing ring 12 facilitates the operation of the positioning shaft 13.

[0033] Working Principle: When installing the lead wire, first pass the lead wire through the wire through hole on one side of the take-up box 2. The fixing sleeve 3 is threadedly connected to the wire through hole of the take-up box 2 by the first external thread 17 on its outside, thus being firmly installed on the take-up box 2, providing a foundation for subsequent operations. After the fixing sleeve 3 is installed, since it has an internal thread, the second external thread 18 on the outside of the compression sleeve 6 can cooperate with it. By rotating the compression sleeve 6, it moves into the fixing sleeve 3. At this time, the multiple through grooves inside the compression sleeve 6 will undergo elastic deformation. The sealing sleeve 7 inside the compression sleeve 6 tightly wraps the lead wire, and together with the sealing ring 4 at one end of the fixing sleeve 3, a double sealing structure is formed, which effectively prevents dust, moisture and other impurities from entering the take-up box 2, ensuring good sealing performance, extending the service life of the lead wire, and improving the stability of the brushless fan operation. The lead wire passes through the positioning sleeve 9 and the limiting sleeve 10. The limiting sleeve 10, through the cooperation of the limiting plate 19 inside the positioning sleeve 9 and its own limiting groove 20, can only move linearly along the axis within the positioning sleeve 9. Inside the limiting sleeve 10, the fixing ring 12 is installed in the mounting groove 11, and the positioning shaft 13 is movably fitted inside the fixing ring 12. The outer diameter of the limiting ring 14 outside is larger than the inner diameter of the fixing ring 12 to prevent the positioning shaft 13 from coming out. The spring 15 is fitted outside the positioning shaft 13, and one end is fixedly connected to the fixing ring 12 and can be compressed or extended. When the limiting sleeve 10 moves linearly along the axis within the positioning sleeve 9, it can squeeze the positioning shaft 13, causing the positioning shaft 13 to move within the fixing ring 12. The spring 15 is compressed or extended, automatically adjusting the pressure of the clamping plate 16 on the lead wire, realizing adaptive clamping for lead wires of different thicknesses. At the same time, the axial linear movement characteristics of the limiting sleeve 10 ensure that the lead wire will not deviate during the clamping process, making the clamping operation more precise and efficient.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
