Description

Technical Field

[0001] The present application relates to the field of winding reels, and in particular, to a composite winding reel. Background Art

[0002] Winding reels are used to wind or store materials, such as paper, wires, ropes, fabrics, etc. It plays the role of facilitating storage, transportation and saving storage space.

[0003] In the related art, a Chinese patent with the authorization announcement number CN203392637U discloses a wire winding reel, which includes a winding roller and retaining discs fixedly installed at both ends of the winding roller. The two ends of the winding roller are frustum cones with a diameter gradually increasing from the inside to the outside, and the maximum diameter of the frustum cone is slightly smaller than that of the retaining disc. A positioning snap ring protruding outward is provided on the outer side of one of the retaining discs, and a card slot corresponding to the positioning snap ring is provided on the outer side of the other retaining disc.

[0004] During production, the winding roller and the two retaining discs are usually integrally formed by die injection molding. According to the sizes of winding reels with different specifications, different specifications of injection molds need to be prepared, and then injection molding processing is carried out. However, when injecting some winding reels with larger volumes, corresponding large-sized molds are required, which have higher requirements for processing technology and are not convenient for production, so improvement is needed. Summary of the Utility Model

[0005] In order to improve the problem that it is not convenient to produce winding reels of different sizes, the present application provides a composite winding reel.

[0006] The composite winding reel provided by the present application adopts the following technical solution:

[0007] A composite winding reel includes a cylinder and two discs. The cylinder is located between the two discs, and the two ends of the cylinder correspond to the discs one by one. An installation hole is provided on the side wall of the disc close to the cylinder, and the installation hole is coaxial with the disc. The end of the cylinder is coaxially inserted into the corresponding installation hole, and the outer wall of the cylinder is threadedly connected to the inner wall of the installation hole.

[0008] By adopting the above technical solution, during production, the cylinder and the two discs with corresponding sizes are injection molded by a mold. Then, one end of the cylinder is inserted into the installation hole of one of the discs, and the cylinder is screwed to make the outer wall of the cylinder threadedly connected to the inner wall of the installation hole, so as to fix the cylinder and the disc. Subsequently, the other disc is sleeved on the other end of the cylinder, that is, the cylinder is inserted into the installation hole of the disc, and then the disc is screwed to fix the cylinder and the other disc, realizing the assembly of the whole winding reel. After that, only the cylinder and the disc with corresponding sizes need to be produced and then assembled to obtain winding reels of different sizes, which is more convenient than directly producing the whole winding reel.

[0009] Optionally, a limiting ring is provided in the mounting hole. The limiting ring is coaxial with the disc, and one side of the limiting ring away from the central axis of the disc can contact the inner wall of the cylinder.

[0010] By adopting the above technical solution, after the cylinder is inserted into the mounting hole, the disc is located between the limiting ring and the inner wall of the mounting hole. After the cylinder is threadedly connected to the disc, at this time, the limiting ring abuts against the inner wall of the cylinder, playing a limiting role, so that the cylinder cannot perform eccentric movement in the mounting hole, thereby making the cylinder not easily deviate or tilt, and increasing the stability of the cylinder installed on the disc.

[0011] Optionally, a rubber ring is provided on one side of the limiting ring away from the central axis of the cylinder, and the rubber ring can abut against the inner wall of the cylinder.

[0012] By adopting the above technical solution, after the cylinder is inserted into the mounting hole, the rubber ring is deformed by extrusion. Then, the cylinder is screwed, so that the cylinder slides on the rubber ring. The rubber ring plays a protective role, so that the cylinder is not easily worn, and the service life of the cylinder is prolonged.

[0013] Optionally, a ring groove is formed on the inner wall of the cylinder, and the rubber ring can be inserted into the ring groove.

[0014] By adopting the above technical solution, after the cylinder is inserted into the mounting hole, the cylinder is screwed, so that the cylinder continuously penetrates into the mounting hole until the ring groove moves to the position of the rubber ring. At this time, the rubber ring loses the extrusion of the side wall of the cylinder, so it recovers its deformation and is inserted into the ring groove. The rubber ring abuts against the inner wall of the ring groove, playing a limiting role, so that the cylinder is not easily removed from the mounting hole, and the stability of the cylinder inserted into the mounting hole is increased.

[0015] Optionally, a cavity is formed in the rubber ring, and a spring is provided in the cavity. The spring is used to push the rubber ring away from the central axis of the disc.

[0016] By adopting the above technical solution, after the rubber ring is inserted into the ring groove, the spring increases the elastic force of the rubber ring, so that the rubber ring needs to be subjected to greater pressure to deform, thereby making the rubber ring not easily removed from the ring groove, and further increasing the stability of the cylinder inserted into the mounting hole.

[0017] Optionally, a plurality of reinforcing ribs are provided on the side of the disc away from the cylinder, and the plurality of reinforcing ribs are arranged radially with the center of the disc as the center.

[0018] By adopting the above technical solution, the reinforcing ribs improve the stability of the disc structure, so that the disc is not easily bent and deformed.

[0019] Optionally, a plurality of positioning holes are formed through the disc, and a plurality of fixing holes are formed in the end wall of the cylinder. The plurality of fixing holes correspond to the positioning holes one by one. A screw is inserted through the positioning hole. One end of the screw can be inserted into the fixing hole, and the screw is threadedly connected to the inner wall of the fixing hole.

[0020] By adopting the above technical solution, after the cylinder is inserted into the mounting hole and threadedly connected to the disc, the fixing holes on the cylinder move to align with the positioning holes. Then, the screw is rotated so that the screw is inserted into the fixing hole and threadedly connected to the cylinder, so that the screw will not separate from the cylinder. And the screw is located in the positioning hole, so that the screw cannot move around the central axis of the disc, so that the cylinder cannot rotate, that is, the cylinder will not rotate out of the mounting hole, increasing the stability of the cylinder mounted on the disc.

[0021] Optionally, a limiting block is fixed to one end of the screw away from the cylinder, and the limiting block can abut against the side of the disc away from the cylinder.

[0022] By adopting the above technical solution, after the screw is inserted into the fixing hole and threadedly connected to the cylinder, the limiting block abuts tightly against the side wall of the disc, so that the screw cannot move, increasing the stability of the connection between the screw and the disc, thereby increasing the stability of the connection between the cylinder and the disc. At the same time, the limiting block can also be used as a handle to provide a force application part for the hand, facilitating the screwing of the screw.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. During production, the corresponding-sized cylinder and two discs are injection-molded using a mold. Then, one end of the cylinder is inserted into the mounting hole of one of the discs, and the cylinder is screwed so that the cylinder is threadedly connected to the inner wall of the mounting hole, realizing the fixation of the cylinder to the disc. Subsequently, the other disc is sleeved on the other end of the cylinder, that is, the cylinder is inserted into the mounting hole of the disc, and then the disc is screwed so that the cylinder is fixed to the other disc, realizing the assembly of the entire winding disc. After that, only the corresponding-sized cylinder and disc need to be produced and then assembled to obtain winding discs of different sizes, which is more convenient than directly producing the integral winding disc;

[0025] 2. When the cylinder is inserted into the mounting hole, the disc is located between the limiting ring and the inner wall of the mounting hole. After the cylinder is threadedly connected to the disc, at this time, the limiting ring abuts against the inner wall of the cylinder, playing a limiting role, so that the cylinder cannot perform eccentric movement in the mounting hole, so that the cylinder is not easily offset and tilted, increasing the stability of the cylinder mounted on the disc.

[0030] The following will Figures 1-3 further elaborate on the present application in conjunction with the attached

[0031] The embodiment of the present application discloses a composite winding reel. Referring to Figure 1 and Figure 2 , the composite winding reel includes a cylinder 10 and two discs 20. The two discs 20 are arranged oppositely. Mounting holes 21 are provided on one side of the two discs 20 close to each other. The mounting holes 21 are coaxial with the discs 20. The cylinder 10 is located between the two discs 20. The two ends of the cylinder 10 correspond to the discs 20 one by one. The end of the cylinder 10 is coaxially inserted into the corresponding mounting hole 21. The outer wall of the cylinder 10 is threadedly connected with the inner wall of the mounting hole 21, or directly adhesively fixed, to realize the assembly of the entire winding reel.

[0032] Among them, the cylinder 10 and the disc 20 are both independent, so as to implement segmented production. That is, hereafter, only the cylinder 10 and the disc 20 with corresponding sizes need to be produced, and then assembled to obtain winding reels of different sizes, which is more convenient than directly producing the whole winding reel.

[0033] Referring to Figure 1 and Figure 3 , to increase the stability of the cylinder 10 inserted into the mounting hole 21, a limiting ring 30 is fixed on the inner wall of the mounting hole 21. The limiting ring 30 is coaxial with the disc 20. When the cylinder 10 is inserted into the mounting hole 21, the cylinder 10 is located between the limiting ring 30 and the inner side wall of the mounting hole 21. A rubber ring 40 is fixed on the side of the limiting ring 30 away from the central axis of the cylinder 10. The rubber ring 40 can abut against the inner wall of the cylinder 10. An annular groove 11 is provided on the inner wall of the cylinder 10. The rubber ring 40 can be inserted into the annular groove 11.

[0034] After the cylinder 10 is inserted into the mounting hole 21, the rubber ring 40 is deformed under extrusion. Then, the cylinder 10 is rotated and screwed, causing the cylinder 10 to slide on the rubber ring 40. The rubber ring 40 plays a protective role, making the cylinder 10 not easily worn and extending the service life of the cylinder 10. When the annular groove 11 moves to the position of the rubber ring 40, at this time, the rubber ring 40 loses the extrusion of the side wall of the cylinder 10, so it restores its deformation and is inserted into the annular groove 11. The rubber ring 40 abuts against the inner wall of the annular groove 11, playing a limiting role, making the cylinder 10 not easily removed from the mounting hole 21 and increasing the stability of the cylinder 10 inserted in the mounting hole 21.

[0035] Refer to Figure 1 and Figure 3 , to increase the stability of the rubber ring 40 inserted into the annular groove 11, a cavity 41 is provided in the rubber ring 40. A spring 42 is arranged in the cavity 41. The end of the spring 42 is fixed to the inner wall of the cavity 41. The spring 42 is used to push the rubber ring 40 in the direction away from the central axis of the disc 20. The spring 42 increases the elastic force of the rubber ring 40, making the rubber ring 40 require a greater pressure to deform, so that the rubber ring 40 is not easily removed from the annular groove 11, further increasing the stability of the cylinder 10 inserted in the mounting hole 21.

[0036] Refer to Figure 1 and Figure 3 , after the cylinder 10 is installed on the disc 20, in order to prevent the cylinder 10 from rotating and rotating out of the mounting hole 21, a number of positioning holes 22 are penetrated through the disc 20. A number of fixing holes 12 are provided on the end wall of the cylinder 10. The number of fixing holes 12 corresponds to the positioning holes 22 one by one. A screw 60 is inserted through the positioning hole 22. One end of the screw 60 can be inserted into the fixing hole 12, and the screw 60 is threadedly connected to the inner wall of the fixing hole 12. A limiting block 61 is fixed to the end of the screw 60 away from the cylinder 10. When the screw 60 is inserted into the fixing hole 12 and threadedly connected to the inner wall of the fixing hole 12, the limiting block 61 abuts tightly against the disc 20.

[0037] After the cylinder 10 is inserted into the mounting hole 21 and threadedly connected to the disc 20, the fixing hole 12 on the cylinder 10 moves to align with the positioning hole 22. Then, the screw 60 is rotated, causing the screw 60 to be inserted into the fixing hole 12 and threadedly connected to the cylinder 10, so that the screw 60 will not separate from the cylinder 10. And the screw 60 is located in the positioning hole 22, making the screw 60 unable to move around the central axis of the disc 20, so that the cylinder 10 cannot rotate, that is, the cylinder 10 will not rotate out of the mounting hole 21, increasing the stability of the cylinder 10 installed on the disc 20.

[0038] Meanwhile, the limiting block 61 abuts against the side wall of the disc 20, making the screw 60 unable to move, increasing the stability of the connection between the screw 60 and the disc 20, and thus increasing the stability of the connection between the cylinder 10 and the disc 20. At the same time, the limiting block 61 can also be used as a handle to provide a force application part for the hand, facilitating the screwing of the screw 60.

[0039] Referring Figure 1 and Figure 3 , a plurality of reinforcing ribs 50 are fixed on the side of the disc 20 away from the cylinder 10, and the plurality of reinforcing ribs 50 are arranged radially with the center of the disc 20 as the center. The reinforcing ribs 50 improve the structural stability of the disc 20, making the disc 20 not easily bend and deform.

[0040] The implementation principle of a composite winding disc in an embodiment of the present application is as follows: during production, the cylinder 10 and two discs 20 with corresponding dimensions are injection-molded using a mold. Then, one end of the cylinder 10 is inserted into the mounting hole 21 of one of the discs 20, and the cylinder 10 is screwed to make the cylinder 10 threadedly connected to the inner wall of the mounting hole 21, realizing the fixation of the cylinder 10 and the disc 20. Subsequently, the other disc 20 is sleeved on the other end of the cylinder 10, that is, the cylinder 10 is inserted into the mounting hole 21 of the disc 20, and then the disc 20 is screwed to fix the cylinder 10 and the other disc 20, realizing the assembly of the entire winding disc. After that, only the cylinder 10 and the disc 20 with corresponding dimensions need to be produced and then assembled to obtain winding discs of different sizes, which is more convenient than directly producing an integral winding disc.

[0041] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
