[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, as Figures 1-3 As shown, a bracket for installing power cables includes a frame 1 consisting of a vertical connecting part and a horizontal supporting part. The top of the supporting part of the frame 1 is provided with several spaced support grooves 2. The inner wall of the support grooves 2 is uniformly provided with support cones 3. The support cones 3 are made of flexible material and are arranged in a centripetal shape on the inner wall of the support grooves 2, so that the end of each support cone 3 can be vertically supported between the cable and the support groove 2 to support the cable. At the same time, the support cones 3 can deform under pressure.

[0022] The top of the support groove 2 is covered by a cover 4. The support groove 2 is a semi-circular groove with an upward opening. The cover 4 is an arched shell that matches the support groove 2, ensuring that the channel between the support groove 2 and the cover 4 for the cable to pass through is circular. The bottom sides of the cover 4 are provided with outwardly extending connecting ears, which contact the support end of the frame 1 through the connecting ears. The connecting ears are provided with connecting holes, and the cover 4 and the frame 1 can be connected by bolts. The cover 4 and the support groove 2 form a channel for the power cable to pass through.

[0023] The inner wall of the casing 4 is provided with several anti-slip pieces 5 spaced apart. The anti-slip pieces 5 are made of flexible material. There is a gap between two adjacent anti-slip pieces 5, so that there is enough space between the adjacent anti-slip pieces 5 to ensure that the anti-slip pieces 5 will not affect each other when deformed. The main body of the anti-slip piece 5 is a semi-ring piece. The semi-ring piece is wavy from one side to the other side. The wavy direction of the adjacent anti-slip pieces 5 is the same, which increases the overall length of the anti-slip piece 5 and leaves a stretch margin when the anti-slip piece 5 is deformed. This avoids the anti-slip piece 5 from tearing due to self-stretching during the deformation process. It can also increase the area of ​​the anti-slip piece 5, so that the contact surface between the deformed anti-slip piece 5 and the cable is increased. The distance between adjacent anti-slip pieces 5 is greater than the thickness of the anti-slip piece 5.

[0024] Working principle: when the support is used near the end of the cable, first fix the frame body 1 at the required position, then place the cable inside the supporting groove 2, then cover the cover 4 on the top of the supporting groove 2, and ensure that the anti-skid piece 5 on the inner wall of the cover 4 is waved towards the opposite direction of the overhead direction of the cable, at this time the anti-skid piece 5 on the inner wall of the cover 4 is in contact with the cable, and the cover 4 and the frame body 1 are connected by bolts, in this process the cover 4 and the frame body 1 are gradually fitted, the anti-skid piece 5 on the inner wall of the cover 4 is gradually extruded and deformed, and is bent to the opposite side of the overhead direction of the cable under the action of the wave shape, at the same time the cable is extruded downward to the supporting cone 3, at this time the upper and lower sides of the cable are limited by the anti-skid piece 5 and the supporting cone 3 respectively, and are not in direct contact with the frame body 1 and the cover 4, when the cable shakes, the anti-skid piece 5 and the supporting cone 3 can block the cable from rubbing against the frame body 1, and the bending direction of the anti-skid piece 5 can ensure that the cable will not slide outward when subjected to the overhead direction tension.

[0025] Example 2, as shown in Figure 1 、 2 , 4, and the difference from example 1 is that the anti-skid piece 5 is arranged at both ends of the inner wall of the cover 4 and is uniformly distributed, and a gap is left between the anti-skid pieces 5 arranged at both ends of the cover 4, and the wave-shaped part of the anti-skid pieces 5 on both sides of the gap is opposite, when the support is used between the two ends of the cable, i.e. the overhead position, the operation steps are the same as those of example 1, but when the anti-skid piece 5 is extruded, the anti-skid pieces 5 at both ends of the inner wall of the cover 4 are bent and deformed to both sides under the action of the wave shape, so that when the middle part of the erected cable is subjected to tension in any direction and shakes, the corresponding anti-skid piece 5 tightens the cable, ensuring the stability of the position of the cable.

[0026] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
