[0002] According to relevant national regulations, cables laid vertically or at an angle greater than 45° in cable tunnels, cable trenches, or electrical shafts must be secured to each bracket. When laid horizontally, fixing points should be provided at both ends, on both sides of bends, and every 5 to 10 meters. For cables with large cross-sections, thermal expansion and contraction generate significant forces when the ambient temperature and load current fluctuate. If these forces are concentrated in a single area, they can damage the cable. The purpose of cable fixtures is to distribute the weight of the cable and the thermal forces generated by thermal expansion and contraction to the various fixtures, thereby protecting the cable from mechanical damage.

[0003] Cables are generally fixed using cable ties and fixing clips. Fixing with cable ties has the advantage of convenient construction, but also has the following disadvantages: cable ties have low mechanical strength and are prone to aging, and may not be able to achieve complete fixation in actual operation; cable ties may cause damage or breakage due to improper use; cable ties are at risk of breaking under prolonged stress, causing electrical failures. Fixing with fixing clips requires drilling holes in the cable bracket, which can easily form burrs and scratch the cable's protective layer. In addition, to reduce construction costs, cable trenches and cable shafts generally have limited space, making the installation of cable fixing devices time-consuming and labor-intensive, causing inconvenience to construction and invisibly increasing labor costs.

[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figures 1 to 4 The figure shows a quick-install cable fixing device of the present invention, which includes a base 1 and an upper cover 2. The base 1 is clamped on the cable bracket 3 and is fastened to the cable bracket 3 by a first bolt 4. The base 1 and the upper cover 2 are detachably connected. A first groove 11 is provided on the base 1, and a second groove 21 is correspondingly provided on the upper cover 2. The first groove 11 and the second groove 21 enclose an accommodating space for the cable 7 to pass through. A clamping component 5 is provided in the second groove 21 to fix the cable 7 in the accommodating space.

[0030] like Figure 4As shown, the base 1 is mounted on the cable support 3 and fastened to the cable support 3 via a first bolt 4. In this embodiment, the base 1 is a rectangular parallelepiped structure. A rectangular through-slot 12 is provided on one side of the base 1 for the cable support 3 to engage. The first bolt 4 is threadedly connected to the bottom of the base 1, and the top of the first bolt 4 extends into the through-slot 12. Generally, the cable support 3 is an L-shaped angle steel. One of the flanges of the cable support 3 is inserted into the through-slot 12, and then the first bolt 4 is rotated so that its top abuts against the cable support 3 to fasten the base 1 to the cable support 3. Preferably, the size of the through-slot 12 is slightly larger than or equal to the size of the flange of the cable support 3, making it easier to insert the base 1 into the cable support 3. Moreover, the connection between the base 1 and the cable support 3 via the through-slot 12 eliminates the need to drill holes in the cable support 3, which prevents the formation of burrs that could scratch the cable protective layer. At the same time, the installation between the base 1 and the cable support 3 is simple and convenient, saving time and effort.

[0031] like Figure 1 and Figure 2 As shown, the base 1 and the upper cover 2 are detachably connected. Specifically, the base 1 and the upper cover 2 are detachably connected via a third bolt 6. A first groove 11 is provided on the base 1. The first groove 11 is in an arc-shaped structure and opens upward. An arc-shaped bushing 13 is fixed in the first groove 11. The inner diameter of the bushing 13 is adapted to the outer diameter of the cable 7 to support the bottom of the cable 7. A second groove 21 is correspondingly provided on the upper cover 2. The second groove 21 is also in an arc-shaped structure and opens downward. The first groove 11 and the second groove 21 form an accommodating space for the cable 7 to pass through. A threaded hole 22 is vertically provided on the upper cover 2. The threaded hole 22 is located directly above the bottom of the second groove 21. The central axis of the threaded hole 22 is in the same plane as the central axis of the second groove 21, and the bottom of the threaded hole 22 is connected to the bottom of the second groove 21.

[0032] A clamping assembly 5 is provided in the second groove 21 to secure the cable 7 within the accommodation space. The clamping assembly 5 includes a second bolt 51. The upper portion of the second bolt 51 is threadedly engaged with the threaded hole 22 in the upper cover 2. The bottom of the second bolt 51 extends into the second groove 21. The bottom of the second bolt 51 is rotatably connected to an arc-shaped clamping sleeve 53 via a retaining spring 52. The clamping sleeve 53 is located in the second groove 21. The inner diameter of the clamping sleeve 53 is adapted to the outer diameter of the cable 7. The clamping sleeve 53 clamps the top of the cable 7 and cooperates with the bushing 13 that supports the bottom of the cable 7 to clamp the cable 7.

[0033] like Figure 3As shown, the second bolt 51 is provided with a first retaining groove 511. In this embodiment, the cross-sectional shape of the first retaining groove 511 is arcuate. The clamping sleeve 53 is provided with a second retaining groove 531 and a third retaining groove 532. The second retaining groove 531 and the third retaining groove 532 are both located directly above the top of the clamping sleeve 53. The second retaining groove 531 is located near the outer wall of the arc-shaped clamping sleeve 53 and corresponds to the first retaining groove 511. The retaining spring 52 is located in the groove formed by the first retaining groove 511 and the second retaining groove 531. The second retaining groove 531 is located outside the third retaining groove 532. The bottom end of the second bolt 51 is located within the third retaining groove 532, which is located near the inner wall of the arc-shaped clamping sleeve 53. The cross-sectional shapes of the second retaining groove 531 and the third retaining groove 532 are rectangular, but are not limited to this. The first clamping groove 511 and the second clamping groove 531 are correspondingly arranged and a clamping spring 52 is installed in the groove enclosed by them. The clamping spring 52 connects the lower part of the second bolt 51 to the upper part of the clamping sleeve 53, so that the clamping sleeve 53 and the second bolt 51 are in a relative rotation relationship.

[0034] Because the second bolt 51 is threadedly connected to the upper cover 2, when the second bolt 51 is rotated, the second bolt 51 moves downward in the vertical direction. Since the clamping sleeve 53 is rotationally connected to the second bolt 51, it does not rotate with the second bolt 51, but only moves downward synchronously with the downward movement of the second bolt 51 until the inner wall of the clamping sleeve 53 abuts the outer wall of the cable 7 and clamps the cable 7. When it is necessary to release the cable 7, the second bolt 51 is rotated in the opposite direction to move it upward in the vertical direction, which drives the clamping sleeve 53 below it to move upward with it until the inner wall of the clamping sleeve 53 separates from the top of the cable 7, thereby releasing the cable 7.

[0035] It is important to note that in this embodiment, the cable 7 is completely secured and clamped by the combined action of the bushing 13 provided on the base 1 and the clamping sleeve 53 provided on the upper cover 2. Furthermore, to prevent damage to the cable 7 during clamping, the clamping sleeve 53 and bushing 13 are both made of a polymer material with a certain hardness, preferably hard rubber or resin, but this is not limiting. Any material with elasticity, high hardness, and wear resistance will be acceptable, thereby significantly reducing damage to the cable and lowering the risk of electrical failure.

[0036] When fixing the cable 7, the quick-install cable fixing device of the present invention first clamps the through groove 12 of the base 1 on the flange of the cable holder 3, and rotates the first bolt 4 provided at the bottom of the base 1 to fasten the base 1 to the cable holder 3, and by rotating the third bolt 6, the upper cover 2 and the base 1 are fastened together. At this time, the size of the accommodating space enclosed by the first groove 11 of the base 1 and the second groove 21 of the upper cover 2 is larger than the outer diameter of the cable 7, which is convenient for the cable 7 to pass through the accommodating space. After all the cables 7 have passed through the accommodating space and have been laid, rotate the second bolt 51 on the top of the upper cover 2, so that the second bolt 51 moves downward in the vertical direction and drives the clamping sleeve 53 at its lower part to move downward synchronously until the inner wall of the clamping sleeve 53 abuts against the top of the cable 7 and finally works together with the bushing 13 to clamp the cable 7.

[0037] Although the present invention discloses preferred specific embodiments to achieve the above-mentioned objectives, it is not intended to limit the structural features of the present invention. Any person skilled in the art should know that within the technical spirit of the present invention, any easily conceivable changes or modifications are possible and are all covered by the scope of the patent application of the present invention.
