Description

Technical Field

[0001] The utility model relates to the technical field of cable routing, in particular to a cable tie for penetrating a wall. Background Art

[0002] When wiring cables, they often need to pass through Figure 2 The typical method for threading cables through the wall shown in the figure is to drill holes directly into the wall. This method bundles the wires, which is not conducive to heat dissipation and also carries the risk of damaging the cable sheath during the threading process. To avoid this risk, an insulating tube is usually inserted into the hole before threading the cables in bundles. However, the bundled method does not dissipate heat easily, causing the cable sheath to age more easily. Furthermore, leakage can easily cause fires. Utility Model Content

[0003] The utility model provides a wall-penetrating cable tie to address the deficiencies of the prior art and the adverse effects of bundled cable threading. In addition, the utility model is convenient for storing cables and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A cable tie for wall penetration includes a central column that is penetrated through a wiring hole on a wall. The central column is provided with a plurality of wiring holes, and cables are respectively penetrated through the wiring holes. A first hole is provided at the center of the central column, and a second hole is provided at the other end of the first hole. The diameter of the first hole is larger than the diameter of the second hole. When threading the cables, the cables are passed through each wiring hole to improve the heat dissipation effect and avoid safety problems caused by cable leakage.

[0006] In order to fix the two ends of the wire on the middle column and to stably restrain the wire, a disc is provided at each end of the middle column. The outer circumference of the disc is opened with multiple wire threading grooves. A restraint sleeve is installed on the inner wall of the disc. The restraint sleeve is provided with a restraint hole. A notch is provided on the outer circumference of the restraint sleeve. The projection of the notch is located at the wire threading groove. The restraint sleeve is made of rubber, and the outer circumference of the restraint sleeve is a conical structure. The inner end of the outer circumference of the restraint sleeve is the small end. The restraint sleeve is passed through the two ends of the wire threading hole. The restraint sleeve is wrapped around the outer circumference of the cable due to its shrinkage characteristics, thereby fixing the cable.

[0007] In order to facilitate the fixing operation of the disc and the cable, an inner rod with a diameter matching the first hole is passed through the first hole, and screws are provided at both ends of the inner rod. One of the screws is passed through the second hole, and the discs are respectively sleeved on both ends of the screws. Nuts are provided at the outer ends of the screws, and the nuts are located on the outside of the discs. One of the discs is first fixed by tightening one of the nuts, and then the other nut is tightened under the condition that the inner rod is fixed.

[0008] Furthermore, in order to improve the insulation effect, the center column is made of ceramic.

[0009] Furthermore, in order to fix the center column in the wiring hole, the center column is fixed in the wiring hole through a polyurethane filling material.

[0010] Furthermore, in order to facilitate the contraction of the restraining sleeve to restrain the cable, the two ends of the wire threading hole are conical structures, and the inner end of the conical structure on the wire threading hole is the small end, and the outer periphery of the conical structure on the restraining sleeve is tightly attached to the inner periphery of the conical structure on the wire threading hole.

[0011] Furthermore, in addition to using the above method to fix the center column, the center column can also be fixed in the following way: a round table is provided at each end of the center column, a mounting plate is provided on the round table, a center hole is opened on the mounting plate, the round table is passed through the center hole, and the mounting plate is installed on the wall by bolts. The outstanding feature of this fixing method is that it is easy to install and convenient for later maintenance and other operations.

[0012] Furthermore, in order to facilitate construction and installation, a groove is provided on the outer circumference of the truncated cone, and a convex portion is provided on the inner circumference of the central hole, and the convex portion is inserted into the groove.

[0013] Furthermore, in order to facilitate the movement of the disc in a predetermined direction, a plurality of guide rods are provided on the disc, and the guide rods are passed through the central column.

[0014] Furthermore, in order to facilitate the storage of cables, a plurality of winding rods are installed on the mounting plate, and the cables can be wound on the winding rods.

[0015] Furthermore, in order to protect the cables, a rectangular frame is installed on the mounting plate, and an end plate is installed on the outer end of the rectangular frame by screws, and a plurality of external connection slots are opened on the end plate.

[0016] The advantages of the above technical solution are:

[0017] When the cables pass through the wall, the utility model separates and fixes the cables separately, thereby facilitating heat dissipation of the cables and stably fixing and restraining the cables. BRIEF DESCRIPTION OF THE DRAWINGS
