Description

Technical Field

[0001] This utility model relates to a cable protection device, and more particularly to a zipper sleeve for wrapping cables, belonging to the field of cable management technology. Background Technology

[0002] In various electrical equipment and wiring scenarios, cable protection and organization are crucial. Traditional cable protection methods, such as using ordinary conduits or wrapping tape, have many shortcomings. Conduit installation is relatively complex, and it is difficult to re-thread cables during later maintenance and adjustments; while wrapping tape is easy to install, it offers limited protection for cables and does not facilitate cable sorting and organization.

[0003] Some existing zipper sleeves have revealed numerous problems during practical use. For example, their closure structure is not robust enough; under prolonged use or external pulling, the zipper head may detach or the sleeve body may separate, failing to effectively protect the internal cables. Furthermore, existing zipper sleeves have limited capacity to accommodate a certain number of cables and adapt to different cable specifications, failing to meet increasingly complex wiring needs. Additionally, they lack ease of use; the zipper head design may not be ergonomic, resulting in a poor user experience and increased difficulty in operation. Therefore, a new type of zipper sleeve is needed to address these issues. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a zipper sleeve. Through a unique structural design, it improves the reliability of sleeve closure, enhances cable capacity, and improves operational convenience, effectively solving the problems existing in the practical use of current zipper sleeves. This utility model specifically includes the following technical solutions:

[0005] A zipper sleeve for wrapping cables, the main body of which is made of flexible material, includes: a tube body, one side of which has an umbrella-shaped insert along the tube body direction, and the other side of which has a groove matching the insert along the tube body direction; a first guide strip in the same direction as the insert strip near the tube body; and a second guide strip in the same direction as the groove near the tube body; a zipper head, which has a handle and a C-shaped slot below the handle; the distance between the two ends of the slot is adapted to the distance between the two guide strips when the insert strip and the groove are closed; the zipper head slides through the slot and the guide strip, thereby driving the insert strip to insert into the groove to close the tube body; the tube body has several corrugated strips, which are used to give the zipper sleeve a certain degree of contractility to accommodate more cables.

[0006] Furthermore, the corrugated strips are symmetrically distributed on both sides near the point where the insert and the groove close together.

[0007] Furthermore, the corrugated strips are evenly distributed on the surface of the tube, and the height difference between the crests and troughs of the corrugated strips is between 5 mm and 25 mm, so as to better realize the shrinkage of the zipper sleeve and the cable capacity.

[0008] Furthermore, the cross-sections of the first and second guide strips are adapted to the contact surfaces at both ends of the zipper head to enhance the guiding stability of the guide strips on the zipper head.

[0009] Furthermore, the zipper pull handle is ergonomically designed with an anti-slip texture on its surface, and the curvature of the handle matches the angle of finger grip, making it convenient for users to operate the zipper pull and improving the comfort of use.

[0010] Furthermore, the inner ends of the groove are chamfered along its length, and the chamfers engage with the corners of the insert to prevent the insert from accidentally coming out of the groove and improve the reliability of the tube closure.

[0011] Furthermore, the insert and groove are made of an enhanced flexible material, which has higher wear resistance than the flexible material of the tube body, thus extending the service life of the insert and groove mating structure.

[0012] The advantages of this utility model compared to the prior art are as follows:

[0013] 1. The tube body is closed by incorporating inserts and grooves, along with a zipper pull. In particular, the chamfered edges at both ends of the groove interlock with the corners of the insert, effectively preventing the insert from accidentally dislodging within the groove. This significantly improves the reliability of the tube closure and ensures stable protection for the internal cables.

[0014] 2. The corrugated strips on the tube body give the zipper sleeve a certain degree of flexibility, allowing it to be adjusted to accommodate more cables according to their quantity and specifications.

[0015] 3. The insert and groove are made of reinforced flexible material, which effectively extends the service life of the insert and groove mating structure, reduces damage caused by opening and closing or stress, and lowers maintenance costs and replacement frequency.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] In this implementation plan, directional terms such as "upper," "lower," "left," "right," "front," and "rear" are defined relative to the orientation of the structure as shown in the attached drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the structure.

[0023] like Figure 1-3 The zipper sleeve of this embodiment of the present invention has a tube body 1 with an umbrella-shaped insert 7 on one side along the tube body direction and a groove 6 matching the insert 7 on the other side along the tube body direction. A first guide strip 8, aligned with the insert 7, is located near the insert 7 on the tube body 1, and a second guide strip 9, aligned with the groove 6, is located near the groove 6 on the tube body 1. The zipper head 5 has a handle 4, and a C-shaped slot 3 is located below the handle 4. The distance between the two ends of the slot 3 is adapted to the distance between the two guide strips when the insert 7 and the groove 6 are closed. The zipper head 5 slides through the slot 3 in cooperation with the guide strips, thereby driving the insert 7 to insert into the groove 6 to close the tube body 1.

[0024] The tube body 1 is provided with several corrugated strips 2, which are used to give the zipper sleeve a certain degree of contractility to accommodate more cables. The corrugated strips 2 are symmetrically distributed on both sides near the closure point of the insert 7 and the groove 6. The corrugated strips 2 are evenly distributed on the surface of the tube body 1, and the height difference between the crests and troughs of the corrugated strips 2 is between 5 mm and 25 mm, so as to better realize the contractility of the zipper sleeve and the cable capacity.

[0025] The cross-sections of the first guide bar 8 and the second guide bar 9 are adapted to the contact surfaces at both ends of the zipper head 5 to enhance the guiding stability of the guide bar on the zipper head 5. The handle 4 of the zipper head 5 adopts an ergonomic design, with an anti-slip texture on its surface, and the curvature of the handle 4 matches the angle of finger grip, making it convenient for users to operate the zipper head 5 and improving the comfort of use.

[0026] The groove 6 has chamfers at both ends along its length, which engage with the corners of the insert 7 to prevent the insert 7 from accidentally dislodging from the groove 6 and improve the reliability of the tube body 1 closure. The insert 7 and the groove 6 are made of a reinforced flexible material, which has higher wear resistance than the main flexible material of the tube body 1, extending the service life of the mating structure of the insert 7 and the groove 6.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
