Description

Technical Field

[0001] This utility model relates to the field of street light wire fixing technology, specifically a wire fixing device. Background Technology

[0002] Streetlights are lighting fixtures that provide illumination to roads. They consist of a lamp, wires, a light source, a pole, and an arm. During the installation of the wires inside the pole, a fixing device is needed to secure the wires.

[0003] A Chinese patent with authorization announcement number CN 215892200 U discloses a connecting wire fixing device for solar street lights, relating to the field of solar street lights. Addressing the problem that existing solar street light connecting wires are prone to breakage from their internal mainboard, leading to malfunctions, the patent proposes the following solution: It includes a wire-fixing ring and a fixing plate. The fixing plate is installed inside the wire-fixing ring, and connecting plates arranged in a circular array are connected between the fixing plate and the wire-fixing ring. A driving component is installed on the front of the fixing plate, and a limiting groove arranged in a circular array is formed on the front of the fixing plate. A driven component is movably installed within the limiting groove. This invention has a novel structure, and the device can achieve synchronous adjustment of the positioning plate, positioning and protecting the solar street light connecting wires to prevent them from detaching from the internal mainboard. Simultaneously, it allows multiple strands of the connecting wires to pass through the wire-fixing ring, avoiding excessive wire dispersion, making it suitable for widespread use.

[0004] Existing fixing devices typically place multiple wires in a common conduit during the fixing process inside the light pole, which may cause signal interference and result in poor wire isolation. Therefore, a wire fixing device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a wire fixing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a wire fixing device, including a lamp post. A placement groove is provided inside the lamp post, and a fixing plate is fixedly installed on the inner wall of the placement groove. Multiple pipe holes and multiple plate grooves are opened on the fixing plate. A limiting ring is placed in each plate groove, and a protective tube is fixedly installed on the inner wall of the limiting ring. A sliding groove is symmetrically opened on the inner wall of the protective tube, and a first wire fixing component is placed inside the protective tube. Two connecting rods are installed on the bottom side of the first wire fixing component. The first wire fixing component includes a fixing ring, and two sliders are symmetrically installed on both sides of the fixing ring. The sliders are assembled in the sliding grooves, and threaded holes are opened on the side walls of the fixing ring. The device is internally equipped with a screw, one end of which is fitted with a knob, and the other end of which is rotatably connected to a clamp. Two rod holes are formed on the side wall of the fixing ring, and guide rods are fitted into these holes. The guide rods are fixed to the conductor via a first and a second fixing component. The first fixing component, the two connecting rods, and the second fixing component are then placed inside the protective tube. A slider on the first fixing component slides within a groove until the second fixing component contacts the positioning ring inside the protective tube. At this point, the conductor is fixed inside the protective tube. The protective tube is then placed inside the tube hole, achieving isolated placement of the conductor. This structure can isolate power lines and signal lines, preventing signal interference caused by shared placement of power lines and signal lines, and improving the isolation of the conductor.

[0007] A second wire-fixing component is fixedly installed on the bottom side of the two connecting rods. The second wire-fixing component has the same structure as the first wire-fixing component. A positioning ring is fixedly installed on the inner wall of the protective tube. The positioning ring is located at the bottom end of the protective tube. A wire is placed inside the second and first wire-fixing components. The wire extends to the bottom of the protective tube. An inspection port is opened on the side wall of the lamp post. A sealing plate is installed on the outer wall of the lamp post at the inspection port. An installation plate is installed on the bottom side of the lamp post. A lamp arm is installed at the top of the lamp post. A light source is installed on the lamp arm. The wire is clamped by the first and second wire-fixing components. The wire will not be suspended in the air. Therefore, the wire at the top of the lamp post will not be damaged by gravity, thus protecting the wire and improving its protective performance.

[0008] The advantages of this utility model are:

[0009] 1. This utility model uses a first and a second wire-fixing component to fix the wire. Then, the first wire-fixing component, two connecting rods, and the second wire-fixing component are placed inside a protective tube. The slider on the first and second wire-fixing components slides in the groove until the second wire-fixing component contacts the positioning ring inside the protective tube. At this point, the wire is fixed inside the protective tube. Then, the protective tube is placed inside the tube hole, thus achieving isolated placement of the wire. This structure can isolate power lines and signal lines, avoiding signal interference caused by the co-location of power lines and signal lines, and improving the isolation of the wire.

[0010] 2. This utility model clamps the wire with the first and second wire-fixing components, so the wire will not be suspended in the air. Therefore, the wire located at the top of the lamp post will not be damaged by gravity, thus protecting the wire and improving its protective performance. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-4As shown, a wire fixing device includes a lamp post 1, a placement groove 2 inside the lamp post 1, a fixing plate 3 fixedly installed on the inner wall of the placement groove 2, multiple pipe holes 4 and multiple plate grooves 5 on the fixing plate 3, a limiting ring 6 placed in the plate groove 5, a protective tube 7 fixedly installed on the inner wall of the limiting ring 6, symmetrical sliding grooves 8 on the inner wall of the protective tube 7, a first wire fixing component placed inside the protective tube 7, two connecting rods 9 installed on the bottom side of the first wire fixing component, the first wire fixing component including a fixing ring 10, two sliders 11 symmetrically installed on both sides of the fixing ring 10, the sliders 11 being assembled in the sliding grooves 8, and threaded holes on the side wall of the fixing ring 10. A screw 12 is fitted into the threaded hole. A knob 13 is installed at one end of the screw 12, and a clamping plate 14 is rotatably connected to the other end of the screw 12. Two rod holes are opened on the side wall of the fixing ring 10, and guide rods 15 are fitted into the rod holes. During operation, the existing fixing device usually places multiple wires 18 in a common conduit when fixing the wires 18 in the lamp post 1, which may cause signal interference and result in poor isolation of the wires 18. By placing the wires 18 in the fixing ring 10 of the first and second fixing components 16, a 30-50cm slack is required for the lower end of the wires 18 of the second fixing component 16 for future maintenance. Then, rotating the knob 13 on the first wire-fixing component causes the screw 12 to rotate. The screw 12 causes the clamping plate 14 to move horizontally, pressing the wire 18 against the inner wall of the fixing ring 10, thus achieving a fixed connection between the first wire-fixing component and the wire 18. Similarly, rotating the knob 13 on the second wire-fixing component 16 causes the clamping plate 14 on it to press the wire 18 against the inner wall of the fixing ring 10, thus achieving a fixed connection between the second wire-fixing component 16 and the wire 18. The first wire-fixing component, the two connecting rods 9, and the second wire-fixing component 16 are an integral structure. The first wire-fixing component, the two connecting rods 9, and the second wire-fixing component 16 are then placed inside the protective tube 7, with the slider on top... 11 slides within the groove 8 until the second wire fixing component 16 contacts the positioning ring 17 inside the protective tube 7, thus placing the first wire fixing component, the two connecting rods 9, and the second wire fixing component 16. At this point, the wire 18 is fixed inside the protective tube 7. Then, the protective tube 7 is placed inside the tube hole 4, and the limiting ring 6 on it is locked in the plate groove 5, thus placing the protective tube 7 inside the lamp post 1. Similarly, the above steps are repeated to place multiple wires 18 inside the lamp post 1, thus achieving the isolated placement of the wires 18. This structure can isolate power lines and signal lines, avoiding signal interference caused by the co-placement of power lines and signal lines, and improving the isolation of the wires 18.

[0020] Please see Figure 5As shown, a second wire fixing component 16 is fixedly installed on the bottom side of the two connecting rods 9. The second wire fixing component 16 has the same structure as the first wire fixing component. A positioning ring 17 is fixedly installed on the inner wall of the protective tube 7. The positioning ring 17 is located at the bottom end of the protective tube 7. A wire 18 is placed inside the second wire fixing component 16 and the first wire fixing component. The wire 18 extends to the bottom of the protective tube 7. An inspection port 19 is opened on the side wall of the lamp post 1. A sealing plate 20 is installed on the outer wall of the lamp post 1 at the inspection port 19. An installation plate 21 is installed on the bottom side of the lamp post 1. A lamp arm 22 is installed at the top of the lamp post 1. A light source 23 is installed on the lamp arm 22. During operation, the existing fixing device, in the process of fixing the wire 18 inside the lamp post 1, is prone to damaging the insulation layer under the action of gravity because the wire 18 is suspended for a long time, resulting in poor protection for the wire 18. The conductor 18 is fixedly installed within the first fixing member, two connecting rods 9, and second fixing member 16. The first fixing member, two connecting rods 9, and second fixing member 16 are placed inside the protective tube 7. At this time, the first fixing member and the second fixing member 16 clamp the conductor 18, and the conductor 18 will not be suspended in the air. Therefore, the conductor 18 located at the top of the lamp post 1 will not be damaged by gravity, thus protecting the conductor 18. When the operator is inspecting the conductor 18, it is difficult for the operator to control the pulling force on the conductor 18. Since the first fixing member and the second fixing member 16 clamp the conductor 18, the conductor 18 will not be displaced and will not be pulled at the top of the conductor 18, thus protecting the conductor 18 and improving its protective performance.

[0021] Working principle: In existing fixing devices, multiple wires 18 are usually placed in a common conduit during the fixing process of the light pole 1, which may cause signal interference and result in poor isolation of the wires 18. By placing the wires 18 inside the fixing ring 10 of the first fixing component and the second fixing component 16, a 30-50cm slack is required at the lower end of the wires 18 of the second fixing component 16 for future maintenance. Then, the knob 13 on the first fixing component is rotated, which drives the screw 12 to rotate. The screw 12 drives the clamping plate 14 to move horizontally, and the clamping plate 14 presses the wires 18 against the inner wall of the fixing ring 10, thus achieving a fixed connection between the first fixing component and the wires 18. Similarly, Rotating the knob 13 on the second wire fixing component 16 causes the clamp 14 to press the wire 18 against the inner wall of the fixing ring 10, thus fixing the second wire fixing component 16 and the wire 18. The first wire fixing component, the two connecting rods 9, and the second wire fixing component 16 are an integral structure. Then, the first wire fixing component, the two connecting rods 9, and the second wire fixing component 16 are placed inside the protective tube 7, and the slider 11 on it slides within the groove 8 until the second wire fixing component 16 contacts the positioning ring 17 inside the protective tube 7, thus placing the first wire fixing component, the two connecting rods 9, and the second wire fixing component 16. At this point, the wire 18 is fixed inside the protective tube 7. Then, the protective tube 7 is placed inside the tube hole 4, and its... The limiting ring 6 is engaged within the slot 5, allowing the protective tube 7 to be placed inside the lamp post 1. Similarly, by repeating the above steps, multiple wires 18 are placed inside the lamp post 1, achieving isolated placement of the wires 18. This structure isolates power lines and signal lines, preventing signal interference caused by shared placement of power lines and signal lines, and improving the isolation of the wires 18. Existing fixing devices, when fixing the wires 18 inside the lamp post 1, are prone to damaging the insulation layer under gravity due to the wires 18 being suspended for extended periods, resulting in poor protection for the wires 18. By fixing the wires 18 within the first fixing component, two connecting rods 9, and the second fixing component 16, the first fixing component... The first and second wire-fixing components 16 are placed inside the protective tube 7. At this time, the first and second wire-fixing components 16 clamp the wire 18, and the wire 18 will not be suspended in the air. Therefore, the wire 18 located at the top of the lamp post 1 will not be damaged by gravity, thus protecting the wire 18. When the operator is inspecting the wire 18, it is difficult for the operator to control the pulling force on the wire 18. Since the first and second wire-fixing components 16 clamp the wire 18, the wire 18 will not be displaced and will not be pulled at the top of the wire 18, thus protecting the wire 18 and improving the protection of the wire 18.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
