[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. The following embodiments are used to illustrate this utility model but should not be used to limit its scope.

[0021] The following is combined with Figures 1 to 5 This utility model describes a wire spool fixing structure, comprising: a rotating shaft 2, the first end of which is connected to a drive shaft 1; a left conical top 4, which is connected to the rotating shaft 2 near the drive shaft 1; a right conical top 5, which is connected to the rotating shaft 2 away from the drive shaft 1; and a wire spool 3, which includes two symmetrically arranged baffles and a wire winding post connected between the two baffles, the two baffles being respectively connected to the left conical top 4 and the right conical top 5, and a wire winding post having a cable wound on it.

[0022] Preferably, by setting a left conical top 4 and a right conical top 5, it is convenient to connect coils 3 of different specifications, thereby improving the replacement efficiency of coils 3. The left conical top 4 and the right conical top 5 can also effectively prevent axial movement of coils 3 during rotation, ensuring the stability of coil 3 operation. The taper of the left conical top 4 and the right conical top 5 enables coils 3 to produce a self-locking effect when fixed, eliminating the need for additional locking devices, further simplifying the structure and improving the convenience of operation.

[0023] In a preferred embodiment of the wire reel 3 fixing structure of this utility model, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a first flange 11 is provided at the end of the drive shaft 1; The rotating shaft 2 includes a second flange 21 and a shaft 22 connected to the second flange 21. The shaft 22 is threaded. The left conical top 4 has a first threaded hole, and the right conical top 5 has a second threaded hole. The first flange 11 is connected to the second flange 21. The left conical top 4 is screwed to the shaft 22 through the first threaded hole, and the right conical top 5 is screwed to the shaft 22 through the second threaded hole. A limit head 23 is provided on the shaft 22 away from the second flange 21 to facilitate the installation of limit caps and other structures connected to the limit head and the knurled part, thereby improving the connection stability between the right conical top and the rotating shaft.

[0024] Preferably, by providing the first flange 11 and the second flange 21, the connection between the drive shaft 1 and the rotating shaft 2 can be easily achieved, ensuring the stability and reliability of rotation. The threads on the shaft 22, and the first and second threaded holes on the left and right conical mandrels 4 and 5, allow the left and right conical mandrels 4 and 5 to be securely screwed onto the shaft 22, preventing loosening. The limiting head 23 effectively prevents the shaft 22 from detaching from the second flange 21 during rotation, further improving the stability and safety of the structure.

[0025] Furthermore, such as Figure 2 As shown, the left conical top 4 includes a first conical part and a first head, the first head corresponding to the first flange 11, and the baffle connected to the first conical part.

[0026] Preferably, the first head is positioned to facilitate contact and connection with the first flange 11, and the tapered surface of the first conical part can connect to various specifications of coils 3, improving the versatility and adaptability of the coil 3 fixing structure. In practical applications, coils 3 of different specifications can achieve a stable connection by mating with the tapered surface of the first conical part, without needing to replace the entire fixing structure, thereby reducing usage costs. The tapered design of the first conical part can also effectively disperse the stress generated by the coil 3 during rotation, extending the service life of the coil 3.

[0027] Specifically, such as Figure 2 As shown, the first head is provided with an anti-rotation ear 41, and the coil 3 is provided with a third threaded hole 31 corresponding to the position of the anti-rotation ear 41. The anti-rotation ear 41 is provided with a strip hole, and a bolt is passed through the strip hole and the third threaded hole 31 to connect the first head and the coil 3.

[0028] Preferably, by opening a strip hole on the anti-rotation lug 41 and then connecting it to the wire spool 3 with bolts, it is ensured that the wire spool 3 will not loosen due to vibration during rotation, and the connection strength between the wire spool 3 and the left conical top head 4 is also enhanced. The anti-rotation lug 41 effectively prevents the wire spool 3 from deviating during high-speed rotation and improves the overall stability. The strip hole also provides a certain adjustment space, allowing the bolt to be flexibly aligned with the third threaded hole 31 during installation, which simplifies the installation process, improves work efficiency, and facilitates the later maintenance and replacement of the wire spool 3, thereby reducing maintenance costs.

[0029] Preferably, two anti-rotation ears 41 are symmetrically arranged. The two anti-rotation ears 41 can evenly disperse the centrifugal force generated by the coil 3 when it rotates, effectively avoiding the coil 3 from becoming unbalanced or damaged due to excessive force on one side. The symmetrical arrangement of the anti-rotation ears 41 also makes the bolt connection more stable. Even in a high-speed rotating environment, it can ensure a tight connection between the coil 3 and the left conical top 4, without loosening or shifting, thereby extending the service life of the entire fixing structure.

[0030] Specifically, such as Figure 2 As shown, the right conical top head 5 includes a second conical part, a second head and a knurled part connected in sequence. The second conical part and the first conical part are correspondingly arranged. The knurled part corresponds to the limiting head 23. The coil 3 is connected to the second conical part.

[0031] Preferably, the corresponding arrangement of the second conical portion and the first conical portion ensures the coaxiality of the coil 3 during rotation, reducing vibration and noise caused by misalignment. The knurled portion prevents axial movement of the coil 3 and provides an operating surface for easy manual rotation or adjustment, making operation more convenient. The coil 3 is connected to the second conical portion, and the tight fit of the conical surfaces effectively transmits torque, ensuring the stability and reliability of the coil 3 during high-speed rotation.

[0032] Preferably, the knurled part is provided with two flat parts, which are symmetrically arranged. The flat parts on the knurled part facilitate the screwing of the right conical head 5 through the flat parts.

[0033] In one specific implementation, after selecting a reel 3 of the appropriate specification according to the cable length, the two flat parts are clamped with a wrench to unscrew the right conical head 5 from the rotating shaft 2. The reel 3 is then fitted onto the rotating shaft 2, and one baffle of the reel 3 is fitted onto the first conical part of the left conical head 4. The right conical head 5 is then screwed onto the rotating shaft 2, and another baffle of the reel 3 is fitted onto the second conical part of the right conical head 5 to connect the reel 3 to the left conical head 4 and the right conical head 5. The reel 3 is then rotated so that the third threaded hole 31 on the reel 3 aligns with the strip hole of the anti-rotation ear 41. A bolt is then inserted through the strip hole and the third threaded hole 31 to connect the first head and the reel 3, thereby fixing the reel 3 and the left conical head 4 in place.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
