[0001] This utility model belongs to the field of cable laying technology, and in particular relates to a cable laying anti-loosening component. Background Technology

[0002] When various power transmission lines or communication lines are erected (taking cables strung between two utility poles as an example), their middle sections droop with a certain curvature. Especially in remote rural areas, utility poles may tilt due to farm work or geological changes. In this case, the drooping curvature of the cable increases, which may affect agricultural production and transportation. Although document CN107947059B, "A Lifting Mechanism for a Communication Cable Support Pole," discloses a structure that can lift the cable to adjust its slack, its structure is relatively complex and cannot adjust the cable slack on its own. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a cable rack anti-slack component with a simple structure that can adjust the cable tension itself.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A cable tray anti-slack component includes a frame, an inlet groove wheel, an outlet groove wheel, a counterweight groove wheel, and a clamping component. The frame is a vertically arranged strip frame with openings on the front and rear sides. The clamping component is located on the left or right side of the frame. The inlet groove wheel and the outlet groove wheel are both horizontally arranged in the upper inner part of the frame in the left-right direction, and the outlet groove wheel is located in front of the inlet groove wheel. The counterweight groove wheel is horizontally arranged in the frame in the left-right direction and is located below the inlet groove wheel and the outlet groove wheel. The counterweight groove wheel is vertically slidably connected to the inner walls on both sides of the frame. The cable enters the frame from the upper rear side and passes through the inlet groove wheel, the counterweight groove wheel, and the outlet groove wheel in a U-shape to exit forward out of the frame.

[0005] The beneficial effects of the above technical solution are as follows: the cable anti-slackening component can be installed on the utility pole, and the cable can be passed through the anti-slackening component. At this time, the counterweight groove wheel will slide down under the action of gravity to make the cable tensioned, and the cable can also pull the counterweight groove wheel up under the action of external force to buffer.

[0006] The above technical solution also includes two protective plates. The protective plates are installed at the lower ends of the front and rear openings of the frame. The rear protective plate and the frame form an inlet hole, and the front protective plate and the frame form an outlet hole. The cable passes through the inlet hole into the frame and through the outlet hole to exit the frame.

[0008] The above technical solution includes multiple clamping components, which are vertically spaced and arranged on the same side of the frame.

[0009] The beneficial effect of the above technical solution is that it makes the cable tray anti-loosening component more stable when assembled on the utility pole.

[0010] In the above technical solution, the coupling component is horizontally arranged, and its coupling hole is vertically continuous.

[0011] The beneficial effect of the above technical solution is that its structure is simple.

[0012] In the above technical solution, the counterweight grooved wheel is slidably connected to the frame through a counterweight block.

[0013] The beneficial effect of the above technical solution is that it enables the counterweight grooved wheel to use the counterweight block as the mounting carrier, and at the same time, it tends to move downward under the gravity of the counterweight block.

[0014] The inlet groove wheel, outlet groove wheel, and counterweight groove wheel in the above technical solution are all plastic parts.

[0015] The beneficial effect of the above technical solution is that it can reduce the weight of the entire cable tray anti-loosening component.

[0016] The vertical length of the frame in the above technical solution is 0.5-1m.

[0017] The beneficial effect of the above technical solution is that it allows the frame to provide a tension allowance of approximately 1-2m for the cable.

[0018] The counterweight in the above technical solution is a U-shaped seat. The counterweight is vertically arranged in the frame body, and its two side groove walls are vertically slidably connected to the inner walls of the two sides of the frame body. The counterweight groove wheel is horizontally arranged in the counterweight in the left-right direction and is rotatably connected to the groove walls on both sides of the counterweight.

[0019] The advantages of the above technical solution are that it has a simple structure and makes the counterweight grooved wheel installed in the frame body with good stability.

[0020] The above technical solution also includes an elastic element, which is vertically arranged in the frame body and located below the counterweight. The two ends of the elastic element are respectively connected to the lower end of the counterweight and the lower inner end of the frame body. The elastic force of the elastic element is used to drive the counterweight to move downward.

[0021] The beneficial effect of the above technical solution is that the elastic element applies a downward pulling force to the counterweight, thereby improving the tensioning effect of the entire cable rack anti-slack component on the cable.

[0022] The elastic element in the above technical solution is a spring.

[0023] The advantages of the above technical solution are that it has a simple structure and a small size. Attached Figure Description

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0029] like Figures 1-3As shown, this embodiment provides a cable tray anti-slack component, including a frame 1, an inlet grooved wheel 2, an outlet grooved wheel 3, a counterweight grooved wheel 4, and a clamping member 5. The frame 1 is a vertically arranged strip frame with openings on the front and rear sides. The clamping member 5 is located on the left or right side of the frame 1. The inlet grooved wheel 2 and the outlet grooved wheel 3 are both horizontally arranged in the upper inner part of the frame 1 along the left-right direction, with the outlet grooved wheel 3 located in front of the inlet grooved wheel 2. The counterweight grooved wheel 4 is horizontally arranged in the left-right direction inside the frame 1 and located at the inlet grooved wheel 2. Below the guide wheel 2 and the lead wheel 3, and with the counterweight wheel 4 vertically slidingly connected to the inner walls on both sides of the frame 1, the cable 6 enters the frame 1 from the rear top and passes through the guide wheel 2, the counterweight wheel 4 and the lead wheel 3 in a U-shape to pass forward out of the frame 1. In this way, the cable anti-slackening component can be installed on the utility pole. At the same time, the cable passes through the cable anti-slackening component. At this time, the counterweight wheel will slide down under the action of gravity to make the cable taut. Under the action of external force, the cable can also pull the counterweight wheel upward to buffer.

[0030] The above technical solution also includes two protective plates 7. The protective plates 7 are installed at the lower ends of the front and rear openings of the frame 1. The rear protective plate 7 forms an inlet hole 8 between itself and the frame 1, while the front protective plate 7 forms an outlet hole 9 between itself and the frame 1. The cable 6 passes through the inlet hole 8 into the frame 1 and exits through the outlet hole 9 to the outside of the frame 1. This allows the protective plates to partially cover and protect the open sides of the frame, preventing birds from nesting inside. In this embodiment, the protective plates can be installed on the frame using screws. The protective plates on the corresponding open sides of the frame only have holes (forming inlet and outlet holes) exposed at the top for cables to pass through.

[0031] In this embodiment, both the frame and the protective plate can be made of rigid plastic, while the clamping components can be U-shaped clamps or ferrules.

[0032] The above technical solution provides multiple clamping members 5, which are vertically spaced and arranged on the same side of the frame 1. This makes the cable tray anti-slackening component more stable when assembled on the utility pole. The clamping member 5 is horizontally arranged and its clamping hole is vertically through, which makes its structure simple.

[0033] In the above technical solution, the counterweight grooved wheel 4 is slidably connected to the frame 1 via the counterweight block 10, so that the counterweight grooved wheel uses the counterweight block as a mounting carrier and tends to move downward under the gravity of the counterweight block. The counterweight block can be a cast iron part or a lead block.

[0034] The inlet groove wheel 2, outlet groove wheel 3 and counterweight groove wheel 4 in the above technical solution are all plastic parts, which can reduce the weight of the entire cable rack anti-slack component.

[0035] The vertical length of the frame 1 in the above technical solution is 0.5-1m, so that the frame can provide a tension allowance of approximately 1-2m for the cable.

[0036] The counterweight 10 in the above technical solution is a U-shaped seat. The counterweight 10 is vertically arranged in the frame 1, and its two side groove walls are vertically slidably connected to the inner walls of the two sides of the frame 1. The counterweight groove wheel 4 is horizontally arranged in the counterweight 10 in the left-right direction and is rotatably connected to the groove walls on both sides of the counterweight 10. Its structure is simple and makes the counterweight groove wheel have good stability when installed in the frame.

[0037] In this embodiment, the inner walls on both sides of the frame are vertically provided with slide rails 12 corresponding to the counterweights. At this time, the counterweights are directly slidably connected to the frame through the two slide rails.

[0038] The above technical solution also includes an elastic element 11, which is vertically arranged inside the frame 1 and located below the counterweight 10. The two ends of the elastic element 11 are respectively connected to the lower end of the counterweight 10 and the lower inner end of the frame 1. The elastic force of the elastic element 11 is used to drive the counterweight 10 to move downward. In this way, the elastic element applies a downward pulling force to the counterweight, thereby improving the tensioning effect of the entire cable rack anti-slack component on the cable. Preferably, the elastic element 11 is a spring, which has a simple structure and small size.

[0039] By using this cable slack prevention component, the cable between the two utility poles can be kept taut (at which point the cable sags less), maintaining a small sway even in windy weather, while preventing the cable from being damaged by excessive swaying.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
