Description

Technical Field

[0001] This utility model relates to the field of cable sleeve technology, specifically to a cable protection sleeve that is easy to install. Background Technology

[0002] Cable conduits, also known as protective conduits or tubing, are pipes used in electrical installations to protect wires and cables, allowing them to be inserted and replaced. Common types include corrugated protective conduits, which have a slit or notch on their surface to allow multiple cables to be inserted through the notch. However, during the insertion process, the notch usually needs to be manually widened, which carries the risk of cutting fingers. Alternatively, forcibly inserting the cable along the notch risks cutting the cable sheath. Therefore, those skilled in the art propose a cable protection conduit that is easier to install.

The disclosures of various publications, patents, and published patent specifications cited herein are incorporated herein by reference in their entirety. The technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0027] Examples, see attached instruction manual Figure 1 - Appendix Figure 4 As shown;

[0028] A preferred technical solution for an easy-to-install cable protection sleeve includes the following:

[0029] It includes a corrugated protective sleeve 1, with a cable inlet 3 opened inside the outer surface of the corrugated protective sleeve 1, and an installation port expansion piece 2 fixedly connected to both the front and rear ends of the outer ring of the corrugated protective sleeve 1.

[0030] The installation port expansion component 2 includes two arc-shaped pull strips 21 fixed on the left and right sides of the outer ring of the corrugated protective sleeve 1, and a hook 22 fixed on the top end of the arc-shaped pull strip 21 and inserted into the cable insertion port 3. A traction component 23 is fixedly connected to the bottom end of the arc-shaped pull strips 21 that are close to each other.

[0031] The traction assembly 23 includes an inner rotating ring 231 fixed to the bottom end of the left arc-shaped traction bar 21 and an outer rotating ring 233 fixed to the bottom end of the right arc-shaped traction bar 21, and a pivot pin 232 passes through and rotates between the inner rotating ring 231 and the outer rotating ring 233.

[0032] Both the inner rotating ring 231 and the outer rotating ring 233 have protrusions 235 fixedly connected to their top outer rings. Both the inner rotating ring 231 and the outer rotating ring 233 have a pinching plate 234 fixedly connected to their bottom outer rings. The end of the protrusion 235 that is away from the inner rotating ring 231 and the outer rotating ring 233 is fixedly connected to the bottom end of the arc-shaped traction strip 21.

[0033] The inner surface of the arc-shaped pull strip 21 is fixedly connected to the outer ring surface of the corrugated protective sleeve 1 by adhesive. The inner surface of the hook 22 is fixedly connected to the inner cavity side wall of the cable insertion port 3, and the hooks 22 have a spacing of 0.5cm-1.5cm between each other, which is used to allow the cable to be inserted into the inner cavity of the corrugated protective sleeve 1. The inner rotating ring 231 and the outer rotating ring 233 have shaft holes for the shaft pin 232 to pass through at the internal axis position.

[0034] Both ends of the pin 232 are fixedly connected to limit blocks, and the surfaces of the limit blocks that are close to each other are in contact with the surfaces of the inner rotating ring 231 and the outer rotating ring 233 that are far apart from each other. The arc-shaped pull strips 21 are all set in a left-right mirror symmetry with the axis of the pin 232 as the base point. The inner rotating ring 231 and the outer rotating ring 233 are all set in a front-back mirror symmetry with the axis of the pin 232 as the base point. The kneading plates 234 are all set in a left-right mirror symmetry with the axis of the pin 232 as the base point. Several anti-slip grooves are opened on the outer surface of the kneading plates 234.

[0035] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0036] Before cable installation, pinch the pinching plate 234 with your index finger and thumb. As the pinching plate 234 moves closer together, the inner rotating ring 231 and the outer rotating ring 233 rotate along the shaft pin 232, and the protrusions 235 move away from each other. This makes the two arc-shaped pull strips 21 move away from each other. Since the hook 22 is hooked inside the cable inlet 3, the cable inlet 3 expands outward and the space becomes larger.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
