Abstract
Description
Technical Field
[0001] This utility model belongs to the field of thread reel technology, specifically relating to a paper thread reel that is easy to assemble. 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 consists of a cylindrical shaft and two annular retainers fixed to both ends of the shaft.
[0003] Currently, the shaft and retainer are usually fixed with glue and cannot be disassembled. Manufacturers typically assemble them before shipping, which requires a large storage space during transportation, resulting in high transportation costs and inconvenience for individual sellers. In actual use, when the retainer of the existing paper thread reel deforms and affects its use, the entire paper thread reel must be replaced, which is costly. During replacement, the cable wound on the shaft also needs to be transferred to the new paper thread reel, which is time-consuming and labor-intensive. Summary of the Invention
[0004] In order to overcome the shortcomings of the prior art, this utility model provides a paper thread reel that is more convenient for buyers to assemble themselves than the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a paper thread reel that is easy to assemble, comprising a shaft cylinder and an annular baffle. The shaft cylinder is sheet-shaped and includes a starting part, an ending part, and a connecting part. The connecting part is disposed between the starting part and the ending part, and the connecting part has at least three pieces. Indentations are provided at the connection points of adjacent connecting parts, the connection points of the starting part and the connecting part, and the connection points of the ending part and the connecting part. A T-shaped insertion end is provided on the surface of the connecting part facing the baffle. The baffle has a insertion hole for the insertion end to pass through and form a limiting hole. A T-shaped locking end is provided on the surface of the starting part and / or the ending part facing the baffle. The baffle has a locking hole for the locking end to pass through and form a limiting hole.
[0006] Using the above solution, the shaft cylinder remains in a flat state during transportation and storage, requiring less space compared to existing technologies. During use, the shaft cylinder is bent by indentation, and the engagement of the insertion end and insertion hole, as well as the engagement of the locking end and locking hole, keeps the shaft cylinder and the retaining plate relatively fixed, maintaining the cylindrical shape of the shaft cylinder.
[0007] If the baffle plate deforms due to impact during use, affecting its operation, the old baffle plate can be removed and replaced with a new one. When replacing, there is no need to transfer the cable wound on the shaft, making the replacement convenient.
[0008] As a further feature of this utility model, both the starting part and the ending part are provided with locking ends on the surfaces facing the baffle, and the locking ends on the starting part and the ending part are simultaneously inserted into the same locking hole.
[0009] The above solution ensures the stability of the shaft cylinder during actual use.
[0010] As a further feature of this utility model, a T-shaped fixing end is provided on the side of the end portion away from the connecting portion, and a fixing hole is provided on the starting portion for the fixing end to pass through and form a limiting position.
[0011] The above solution facilitates shaft forming and easy fixing of the shaft and baffle. It prevents the starting or ending part from warping, ensuring the normal use of this utility model.
[0012] As a further feature of this utility model, the insertion end includes a long insertion end and a short insertion end, which are spaced apart on different connecting parts. The periphery of the insertion hole for the long insertion end to be inserted is provided with a limiting hole for the long insertion end to be bent and inserted.
[0013] The above solution makes the baffle and shaft cylinder more secure.
[0014] As a further feature of this utility model, the inner edge of the baffle is provided with an annular protrusion, and there is a gap between the outer wall of the protrusion and the inner wall of the shaft cylinder; when the long insertion end is inserted into the limiting hole, the end of the long insertion end away from the connecting part is located between the protrusion and the shaft cylinder.
[0015] Using the above method, when winding cables, the shaft is usually sleeved on the rotating shaft, and the presence of the protrusion makes it convenient for the rotating shaft to be sleeved on the rotating shaft.
[0016] As a further feature of this invention, the inner wall of the protrusion is cylindrical.
[0017] The above solution allows for better fitting onto the rotating shaft.
[0018] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

[0027] Specific embodiments of this utility model are shown in the accompanying drawings.
[0028] A paper thread reel that is easy to assemble includes a shaft cylinder 1 and an annular baffle 2. The shaft cylinder 1 is sheet-shaped and includes a starting part 11, an ending part 12, and a connecting part 13. The connecting part 13 is disposed between the starting part 11 and the ending part 12. There are at least three connecting parts 13. In this embodiment, the shaft cylinder 1 includes seven connecting parts 13. Indentations 14 are provided at the connection points of adjacent connecting parts 13, the connection points of the starting part 11 and the connecting part 13, and the connection points of the ending part 12 and the connecting part 13.
[0029] Adjacent connecting portions 13 are respectively provided with a T-shaped long insertion end 15 and a T-shaped short insertion end 16. Both the long insertion end 15 and the short insertion end 16 are provided on the surface of the connecting portion 13 facing the baffle 2. The baffle 2 is provided with an insertion hole 21 for the long insertion end 15 or the short insertion end 16 to pass through and form a limit. Both the starting portion 11 and the ending portion 12 are provided with a T-shaped locking end 17 on the surface facing the baffle 2. The baffle 2 is provided with a locking hole 22 for the locking end 17 to pass through and form a limit. The locking end 17 on the starting portion 11 and the locking end 17 on the ending portion 12 are simultaneously inserted into a locking hole 22.
[0030] The shaft cylinder 1 is in a flat state during transportation and storage, requiring less space compared to existing technologies. In use, the shaft cylinder 1 is bent by the indentation 14, and then the shaft cylinder 1 and the retaining plate 2 are kept relatively fixed by the cooperation of the long insertion end 15, the short insertion end 16 and the insertion hole 21, and the locking end 17 and the locking hole 22, and the shaft cylinder 1 is kept in a cylindrical shape.
[0031] If the baffle 2 is deformed due to impact during use, the old baffle 2 can be removed and replaced with a new baffle 2. When replacing, there is no need to transfer the cable wrapped on the shaft cylinder 1, making the replacement convenient.
[0032] Both the starting part 11 and the ending part 12 are provided with locking ends 17 to keep the shaft cylinder 1 stable during actual use.
[0033] A T-shaped fixing end 18 is provided on the side of the end portion 12 away from the connecting portion 13, and a fixing hole 19 is provided on the starting portion 11 for the fixing end 18 to pass through and form a limiting hole. The fixing end 18 and the fixing hole 19 cooperate to facilitate the forming of the shaft cylinder 1 and to facilitate the fixing of the shaft cylinder 1 and the baffle 2. This prevents the starting portion 11 or the end portion 12 from tilting up, ensuring the normal use of this utility model.
[0034] In this embodiment, the long insertion end 15 and the short insertion end 16 are spaced apart, and the width a of the connecting portion 13 with the long insertion end 15 is greater than the width b of the connecting portion 13 with the short insertion end 16. The insertion hole 21 for inserting the long insertion end 15 is surrounded by a limiting hole 23 for inserting the long insertion end 15 after bending. This makes the baffle 2 and the shaft cylinder 1 more securely fixed.
[0035] The inner edge of the baffle 2 is provided with an annular protrusion 24, and there is a gap between the outer wall of the protrusion 24 and the inner wall of the shaft cylinder 1. When the long insertion end 15 is inserted into the limiting hole 23, the end of the long insertion end 15 away from the connecting part 13 is located between the protrusion 24 and the shaft cylinder 1. The inner wall of the protrusion 24 is cylindrical. When winding cables, the shaft cylinder 1 is usually sleeved on the rotating shaft. The presence of the protrusion 24 makes it convenient for the rotating shaft to be sleeved on the rotating shaft.
[0036] 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.
