Description

Technical Field

[0001] This utility model relates to the field of plastic reel technology, specifically a stable plastic reel. Background Technology

[0002] Cable reels are commonly used for winding and storing cables, wires, or other types of wires. Their main function is to facilitate the transportation, storage, and use of wires, preventing tangling and damage. Traditional cable reels are mostly made of materials such as metal, wood, or ordinary plastics. With the development of materials science, the plastics industry has seen the emergence of various new high-performance plastics. These plastics are not only lightweight and corrosion-resistant, but also possess good toughness and strength. The development of sturdy plastic cable reels is mainly to overcome the shortcomings of traditional reels, improve their performance and service life, and reduce the overall weight of the reels by using new plastic materials, making transportation and handling easier. These new plastics also have better impact resistance, able to withstand greater external forces, and prevent breakage.

[0003] However, existing technologies still have significant shortcomings, such as:

[0004] In existing technologies, plastic is often used instead of metal to manufacture spools. Plastic spools are lightweight and practical, but they can withstand less force and lack stability compared to metal spools. Therefore, we propose a stable plastic spool. Utility Model Content

[0005] The purpose of this invention is to provide a stable plastic reel to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sturdy plastic reel includes a circumferential portion and a central portion. The central portion has a support cavity inside. A central post is fixedly mounted on one of the circumferential portions, and a slot for the central post to extend into the inner side of the other circumferential portion is provided. The central post extends into the support cavity. The circumferential portion and the central portion are connected by connecting bolts.

[0008] The support cavity is provided with a number of support components for supporting the central part. The support components are spaced apart, and the spacing between the support components decreases sequentially from the circumference to the center of the central part.

[0009] Preferably, the support assembly includes several sleeves mounted on the central column, and several support plates are movably disposed on the inner wall of the support cavity, with the support plates in adjacent support assemblies being staggered.

[0010] The arc of the support plate is the same as the circumference arc of the support cavity, the arc length of the support plate is not less than one-eighth of the circumference of the support cavity, the width of the support plate is not less than 20 centimeters, and the support plate and the column sleeve are connected by a number of support rod assemblies.

[0011] Preferably, the support rod assembly includes a central rod and two side rods, the two side rods being symmetrically arranged about the central rod as an axis of symmetry, and the angle between the side rods and the central rod being thirty degrees.

[0012] Preferably, the number of the support components is odd and not less than 3 sets.

[0013] Preferably, a number of connecting rods are provided between the side rod and the center rod, and the connecting rods are spaced further apart in sequence along the direction toward the column sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The support components ensure the support effect of the center and the overall stability of the coil. At the same time, the distribution of the support components from the center to both sides from dense to comb-like reduces manufacturing costs and provides good support for the parts far from the circumference.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A sturdy plastic reel includes a circumferential portion 1 and a central portion 2. The central portion 2 has a support cavity 3 inside. A central post 4 is fixedly mounted on one of the circumferential portions 1, and a slot 5 is opened on the inner side of the other circumferential portion 1 for the central post 4 to extend into. The central post 4 extends into the support cavity 3. The circumferential portion 1 and the central portion 2 are connected by a connecting bolt 6.

[0027] The central part 2 is the winding part of the line. Two circular parts 1 are provided on both sides. The radius of the circular parts 1 is larger than that of the central part 2. The central part 2 is hollow and has a support cavity 3 inside. A central column 4 that can extend into the support cavity 3 is fixedly connected to the circular part 1. A slot 5 is opened on the other circular part 1. After the central column 4 is inserted into the slot 5, both ends of the central column 4 are supported and can be used as the force points of the support component.

[0028] The support cavity 3 is provided with a number of support components for supporting the central part 2. The support components are spaced apart, and the spacing between the support components decreases sequentially from the circumferential part 1 to the center of the central part 2. The number of support components is odd and not less than 3 sets. In this embodiment, there are 5 sets of support components. The middle set is located at the center of the support cavity 3, and the remaining 4 sets are located on both sides of the middle set. Considering that the force of the central part 2 closer to the circumferential part 1 will be distributed and supported by the circumferential part 1, the weakest part of the central part 2 is the area far away from the two circumferential parts 1. Therefore, the support components in this area should be more densely arranged, while the support components closer to the circumferential part 1 should be sparsely arranged without affecting the support effect, and at the same time, it can save manufacturing costs.

[0029] The support assembly includes several sleeves 7 mounted on the central column 4. Several support plates 8 are movably disposed on the inner wall of the support cavity 3. The support plates 8 in adjacent support assemblies are staggered. The curvature of the support plate 8 is the same as the circumferential curvature of the support cavity 3. The arc length of the support plate 8 is not less than one-eighth of the circumference of the support cavity 3. The width of the support plate 8 is not less than 20 centimeters. Several reinforcing ribs 12 are disposed on the inner wall of the support cavity 3 between adjacent support plates 8. The length of the reinforcing ribs 12 is the same as the width of the support plate 8. Several support rod assemblies connect the support plates 8 and the sleeves 7. This document discloses one possible implementation of the support assembly structure. The sleeves 7 can be disposed on the central column 4 in two ways: one is a fixed disposal, and the other is a sliding disposal.

[0030] Example 1: Fixed setting; This case does not need much description. It is for a specific model of coil that needs to be mass-produced. First, the column sleeve 7 is adjusted to a suitable position, and then it can be mass-produced in a fixed manner. In this setting, the support plate 8 can also be fixedly set on the inner wall of the support cavity 3.

[0031] Example 2: The column sleeves are slidably configured. This configuration is mainly to address a situation in production where the length of the central part 2 of the production coil is not fixed, but the diameter of the support cavity 3 inside the central part 2 is fixed. One side of the circumferential part 1 can be removed, and multiple sets of column sleeves 7 can be fitted onto the central column 4 depending on the specific situation. Of course, the number of column sleeves 7 is the same as the number of support components. The sliding between the column sleeves 7 and the central column 4 is a damped sliding mechanism, which can be fixed after sliding or rotating to a certain point. This is a damping configuration well known to those skilled in the art, and will not be elaborated here. This allows for appropriate adjustment of the number and position of the support components to meet more production needs. In this case, the reinforcing rib 12 can serve as a limiting device for the sliding of the support piece 8. Of course, the reinforcing rib 12 is to ensure the strength of the central part 2 at the interval of the support piece 8, not just to limit the sliding of the support piece 8.

[0032] The support plates 8 on adjacent support components are staggered, which means that the support plates 8 on multiple sets of support components can support the axial or radial position of the inner wall of the support cavity 3, and all the support plates 8 will not support the same axial or radial position of the inner wall of the support cavity 3. The staggered arrangement provides better support.

[0033] The support rod assembly includes a central rod 9 and two side rods 10. The two side rods 10 are symmetrically arranged about the central rod 9 as the axis of symmetry. The angle between the side rods 10 and the central rod 9 is 30 degrees. Several connecting rods 11 are arranged between the side rods 10 and the central rod 9. The connecting rods 11 increase in intervals along the direction toward the column sleeve 7. The two ends of the central rod 9 and the side rods 10 are fixedly connected to the support plate 8 and the column sleeve 7, respectively. The arrangement of the central rod 9 and the side rods 10 forms a support triangle, which can ensure better support for the support plate 8, that is, better support for the central part 2.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
