Description

Technical Field

[0001] This utility model belongs to the field of thread reel technology, specifically relating to a paper thread reel that facilitates thread winding. Background Technology

[0002] A paper spool is a cable storage and support device made primarily of paper material. It is mainly used for winding wires, cables, 3D printing filaments, and connecting terminals, and is characterized by its environmental friendliness and lightweight design. A paper spool typically includes a cylinder, a retaining plate, and a plug.

[0003] When winding cables onto a paper reel, the cable end needs to be secured to the reel. Factories typically use winding machines with clamps to hold the cable end in place. However, winding machines are limited to fixed locations, making them inconvenient to move and costly, unsuitable for individual buyers with small order volumes. Individual buyers usually wind cables manually, requiring them to hold the cable end and release it after a certain number of turns, which is cumbersome. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, this utility model provides a paper thread reel that is convenient for manual winding.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a paper thread reel for easy winding, comprising two baffles, two plugs, and two cylinders. The two plugs each include a limiting part and a mating part. The limiting part abuts against the side of the baffle facing away from the cylinder. The mating part passes through the baffle and is press-fitted with the inner wall of the cylinder. The outer wall of the cylinder has a mating cavity extending to the inner wall of the cylinder. The outer wall of the mating part has a groove opposite to the mating cavity. A fixing block press-fitted with the groove is provided in the groove. The fixing block has a limiting groove on its surface facing the bottom of the groove. The side of the fixing block away from the bottom of the groove protrudes from the groove, and the protruding part press-fitted with the mating cavity.

[0006] Using the above solution, the fixing block and the shaft cylinder are separately configured during transportation or storage. When winding is required, the end of the cable is embedded in the limiting groove, so that the end of the cable is interference-fitted with the groove. Then, the fixing block is embedded in the groove, so that the fixing block is interference-fitted with both the groove and the mating cavity, thereby fixing the end of the cable to the shaft cylinder and facilitating subsequent winding.

[0007] The fixing blocks are set independently, and fixing blocks with different limit groove shapes can be used according to the shape of the cable end to achieve a better fixing effect.

[0008] As a further feature of this invention, the size of the groove is larger than the size of the mating cavity, and the two opposite side walls of the fixing block are provided with limiting ends, which are embedded in the groove and form a limiting relationship with the inner wall of the shaft cylinder.

[0009] Using the above solution, after the fixing block is embedded in the groove, the limiting end forms a limiting position with the inner wall of the shaft cylinder, which can achieve a better limiting effect.

[0010] The fixing block and the limiting end are preferably set as an integral part.

[0011] As a further feature of this utility model, the shaft cylinder is provided with a guide groove that communicates with the limiting groove. The guide groove extends circumferentially along the shaft cylinder, and the depth of the guide groove gradually increases from the side away from the limiting groove to the side close to the limiting groove.

[0012] Using the above scheme, the depth of the guide groove refers to the distance from the opening of the guide groove to the bottom of the groove along the radial direction of the shaft cylinder.

[0013] After the cable end is interference-fitted with the limiting groove, a small section of the cable protruding from the limiting groove is interference-fitted with the guide groove to facilitate subsequent winding and prevent the cable from being bent, ensuring the normal use of the cable end.

[0014] As a further feature of this invention, the opening of the guide groove facing the limiting groove is smaller than the opening of the limiting groove facing the guide groove.

[0015] The above method achieves a better fixation effect.

[0016] As a further feature of this invention, the bottom of the limiting groove is inclined, and the side of the bottom of the limiting groove furthest from the guide groove is inclined toward the axis of the shaft cylinder.

[0017] Using the above method can ensure that the cable will not be bent.

[0018] As a further feature of this invention, the mating cavity is located on the side of the shaft cylinder near one of the baffles.

[0019] The above method facilitates wire winding.

[0020] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] Specific embodiments of this utility model are shown in the accompanying drawings.

[0027] A convenient paper thread reel includes two baffles 1, two plugs 2, and two cylinders 3. The two baffles 1 are annular, and the two plugs 2 include a limiting part 21 and a mating part 22. The limiting part 21 abuts against the side of the baffle 1 facing away from the cylinder 3. The mating part 22 passes through the baffle 1 and is press-fitted with the inner wall of the cylinder 3. The outer wall of the cylinder 3 is provided with a mating cavity 31 extending to the inner wall of the cylinder 3. The outer wall of the mating part 22 is provided with a groove 23 opposite to the mating cavity 31. The groove 23 is provided with a fixing block 4 press-fitted with the groove 23. The fixing block 4 is provided with a limiting groove 41 on the surface facing the bottom of the groove 23. The side of the fixing block 4 away from the bottom of the groove 23 protrudes from the groove 23, and the protruding part is press-fitted with the mating cavity 31.

[0028] In this invention, the fixing block 4 and the shaft cylinder 3 are separately configured for transportation or storage. When winding is required, the end of the cable is inserted into the limiting groove 41, so that the end of the cable is press-fitted with the groove 23. Then, the fixing block 4 is inserted into the groove 23, so that the fixing block 4 is press-fitted with both the groove 23 and the mating cavity 31, thus fixing the end of the cable to the shaft cylinder 3, which facilitates subsequent winding. The fixing block 4 is set independently, and fixing blocks 4 with different shapes of limiting groove 41 can be used according to the shape of the cable end to achieve a better fixing effect.

[0029] The size of the groove 23 is larger than the size of the mating cavity 31. Limiting ends 42 are provided on the opposite side walls of the fixing block 4. The limiting ends 42 are embedded in the groove 23 and form a limiting position with the inner wall of the shaft cylinder 3. After the fixing block 4 is embedded in the groove 23, the limiting ends 42 form a limiting position with the inner wall of the shaft cylinder 3, achieving a better limiting effect. In this embodiment, the fixing block 4 and the limiting ends 42 are integrally formed.

[0030] The shaft cylinder 3 is provided with a guide groove 32 that communicates with the limiting groove 41. The guide groove 32 extends circumferentially along the shaft cylinder 3, and the depth of the guide groove 32 gradually increases from the side away from the limiting groove 41 to the side closer to the limiting groove 41. The depth of the guide groove 32 refers to the distance from the opening of the guide groove 32 to the bottom of the groove along the radial direction of the shaft cylinder 3. After the end of the cable is interference-fitted with the limiting groove 41, a small section of the cable protruding from the limiting groove 41 is interference-fitted with the guide groove 32 to facilitate subsequent winding and prevent the cable from being bent, ensuring the normal use of the cable end.

[0031] The opening of the guide groove 32 facing the limiting groove 41 is smaller than the opening of the limiting groove 41 facing the guide groove 32. This results in a better fixing effect.

[0032] The bottom of the limiting groove 41 is inclined, with the side of the bottom of the limiting groove 41 away from the guide groove 32 tilting towards the axis of the shaft cylinder 3. This ensures that the cable will not be bent.

[0033] The mating cavity 31 is located on the side of the shaft cylinder 3 near one of the retaining plates 1. This facilitates winding.

[0034] This utility model is not limited to the specific embodiments described above. Those skilled in the art can implement this utility model using other specific embodiments based on the content disclosed in this utility model. Any simple changes or modifications made to the design structure and concept of this utility model will fall within the protection scope of this utility model.
