[0002] Cables, as a common item in power transmission, can transmit current from one end to the other. When laying cables, brackets are usually used to support them.

[0003] Currently, when using brackets to support cables, the brackets and cable sidewalls are usually installed and fixed together. Then, the cable is laid out. After the cable is laid out, it is placed on the bracket. Then, the cable is pulled to the next bracket and laid on the next bracket. The above operation is repeated to achieve the effect of supporting the cable.

[0004] However, when the cable is moved towards the next support, the cable surface will rub against the previous support, resulting in scratches that can easily damage the cable sheath.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0017] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] A cable laying bracket, such as Figures 1-6 As shown, the system includes a support body 1 with several grooves 16. A rotating wheel 2 is rotatably connected to each groove 16. Several rubber strips 3 are fixedly connected to the support body 1 to secure the cable to the rotating wheel 2. The rubber strips 3 and the support body 1 are interlocked by a snap-fit ​​assembly. When supporting the cable, the cable is placed on the rotating wheel 2 of the support body 1, and then the cable is pulled, causing the rotating wheel 2 to rotate. The rotating wheel 2 reduces friction between the cable and the support body 1, thereby reducing the possibility of scratches on the cable surface and improving the protection of the cable. After the cable is laid, the rubber strips 3 are pulled to cover the cable, and the cable and the support body 1 are interlocked by the snap-fit ​​assembly, thus achieving the effect of fixing the cable and the support body 1 together and preventing the cable from detaching from the support body 1.

[0020] Furthermore, the side wall of the rotating wheel 2 is fitted with a rubber layer 14, which can further improve the protection effect of the rotating wheel 2 on the cable. At the same time, the rubber layer 14 can also provide insulation, further improving the safety of the support. The rotating wheel 2 is provided with a guide groove 15 for the cable to slide. When the cable moves on the rotating wheel 2, the guide groove 15 can prevent the cable from swaying left and right on the rotating wheel 2, and can also prevent the cable from detaching from the rotating wheel 2 during movement, thus improving the stability of the cable during movement.

[0021] like Figures 1-6 As shown, the snap-fit ​​assembly includes a rotating rod 4 rotatably connected to the bracket body 1, a limiting rod 5 fixedly connected to the rotating rod 4, and a plurality of strip-shaped grooves 6 for the limiting rods 5 to insert into the rubber strip 3. When the limiting rods 5 and the strip-shaped grooves 6 interlock, the rubber strip 3 and the limiting rods 5 snap together. When snapping the rubber strip 3 and the bracket body 1 together, the rubber strip 3 covers the cable and abuts against the cable. Then, the limiting rods 5 are inserted into the strip-shaped grooves 6 on the rubber strip 3, and then the limiting rods 5 are rotated so that the limiting rods 5 and the strip-shaped grooves 6 are interlocked. At this time, the limiting rods 5 and the strip-shaped grooves 6 cannot be separated, thus achieving the effect of snapping the rubber strip 3 and the bracket body 1 together. When it is necessary to separate the two, simply rotate the limiting rods 5 again to keep the limiting rods 5 and the strip-shaped grooves 6 in the same direction, and then apply a pulling force to the rubber strip 3 to pull it off the limiting rods 5, thereby achieving the effect of separating the two.

[0022] like Figures 1-6 As shown, rotating blocks 7 are fixedly connected to both sides of the rotating wheel 2. The side wall of the groove 16 is provided with a sliding groove 8 for the rotating block 7 to slide. Several limiting teeth 9 are fixedly connected to the bottom of the sliding groove 8. Several limiting slots 10 arranged in a ring array are provided on the side wall of the rotating block 7 for the limiting teeth 9 to insert into. A rotating ring 11 is rotatably connected to the rotating block 7. The rotating ring 11 and the bottom of the groove 16 are connected by a spring 12. When the spring 12 is in its natural state, the limiting teeth 9 and the limiting slots 10 are separated from each other. A connecting plate 13 is fixedly connected to the side wall of the rotating ring 11. The two ends of the spring 12 are connected to the connecting plate 13 and the bottom of the groove 16, respectively, which further limits the connection between the spring 12 and the connecting plate 13 and can reserve enough space for the spring 12 to deform, so that the spring 12 can deform.

[0023] When the rubber strip 3 covers the cable, pressure is applied to the cable through the rubber strip 3, and the pressure is transmitted to the rotating wheel 2. The rotating wheel 2 drives the rotating block 7 to move downward along the slide groove 8. The rotating block 7 also drives the rotating ring 11 to move in the same direction, causing the spring 12 between it and the groove 16 to deform and compress. When the limiting tooth 9 on the rotating block 7 is inserted into the limiting groove 10, the rotating block 7 cannot rotate due to the influence of the limiting tooth 9, which in turn prevents the rotating wheel 2 from rotating. Then the rubber strip 3 and the bracket body 1 are interlocked. At this time, the cable is clamped by the rubber strip 3 and the rotating wheel 2, which further improves the fixing effect of the cable on the bracket body 1.

[0024] The working principle of this utility model is as follows: When supporting the cable, the cable is placed on the rotating wheel 2 of the bracket body 1. Then, the cable is pulled, causing the rotating wheel 2 to rotate. The rotating wheel 2 reduces friction between the cable and the bracket body 1, thereby reducing scratches on the cable surface and improving cable protection. After the cable is laid, the rubber strip 3 is pulled, transmitting pressure to the rotating wheel 2, which drives the rotating block 7 to move downward along the slide groove 8. The rotating block 7 also drives the rotating ring 11 to move in the same direction, so that the spring between it and the groove 16... When deformation and compression occur, and the limiting tooth 9 on the rotating block 7 is inserted into the limiting groove 10, the rotating block 7 cannot rotate due to the influence of the limiting tooth 9, which in turn prevents the rotating wheel 2 from rotating. Then, the limiting rod 5 is inserted into the strip groove 6 on the rubber strip 3, and then the limiting rod 5 is rotated so that the limiting rod 5 and the strip groove 6 are intersected. At this time, the limiting rod 5 and the strip groove 6 cannot be separated. At this time, the cable is clamped by the rubber strip 3 and the rotating wheel 2, thereby achieving the effect of fixing the cable and the bracket body 1 to each other and preventing the cable from detaching from the bracket body 1.

[0025] Experiments have shown To further verify the beneficial effects of this utility model, the following comparative experiment was conducted.

[0026] Experimental conditions: Experimental group: The cable laying bracket of this utility model was used.

[0027] Control group: Commercially available traditional grooved mounting brackets without rotating wheels were used.

[0028] Experimental cable: VV type 4x185mm² power cable.

[0029] Experimental Method: Under the same load (50kg vertical pressure), a force gauge was used to drag the cable horizontally at a speed of 0.5 m / s, moving it 10 meters on the support. The average dragging force required was recorded. After dragging, the surface wear of the cable-support contact area was observed using a 10x magnifying glass.

[0030] Experimental results:

[0031] Experimental conclusion: As can be seen from the above comparative experiments, this utility model transforms the sliding friction of the cable during movement into rolling friction by rotating wheel 2, which greatly reduces the pulling force required for dragging and significantly reduces wear on the cable sheath, proving that it has outstanding substantive features and significant progress.

All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
