A pay-off device for electrical installations

Abstract

This utility model relates to the field of cable laying technology and discloses a cable laying device for power installation. A conductor assembly is provided on the outer side of the base, and a placement assembly is installed on the top of the base. This utility model works by inserting one end of the cable into the conductor ring and then pulling that end of the cable. The cable pulls the rotating shaft at one end of the fixing plate through the conductor ring, causing it to rotate inside the fixing base. The telescopic spring is compressed, and the rotating shaft causes one end of the eccentric block to disengage from the outer side of the support base. The cable then pulls the placement plate and cable roller to rotate, thus enabling orderly cable laying. When not laying cables, the telescopic spring drives the rotating shaft at one end of the fixing plate to rotate and reset inside the fixing base, causing the eccentric block to abut against the outer side of the support base. This provides a limiting brake to the placement plate, preventing the cable roller on the placement plate from continuing to rotate due to inertia, avoiding the problem of cable tangling on the cable roller, and improving the practicality of the device.

Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, specifically a cable laying device for power installation. Background Technology

[0002] Electric wires and cables are wire products used to transmit electrical (magnetic) energy, information, and realize electromagnetic energy conversion. They are mainly composed of conductors, insulation layers, shielding layers, and sheaths, and material costs account for 80-90%. They are divided into five categories: bare wire products, power cables, electrical equipment wires and cables, communication cables and optical fibers, and winding wires. The model name uses letter combinations to indicate material characteristics, such as ZC-YJV22 representing a flame-retardant Class C cross-linked polyethylene insulated steel tape armored cable.

[0003] Traditional cable reel devices can lay cables in an orderly manner during use, but when the cable pulling stops, the reel continues to rotate due to inertia, causing the cables to scatter and pile up. If the loose cables become tangled, they need to be manually reorganized, which is inconvenient. Therefore, a cable laying device for power installation is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a cable laying device for power installation, so as to solve the problem of the traditional cable roller laying device mentioned in the background art. Although it can complete the orderly laying of cables during use, when the cable is stopped, the roller will continue to rotate due to inertia, causing the cables to pile up loosely. If the loose cables get tangled, they need to be manually reorganized, which is quite inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire-laying device for power installation, comprising... A base, wherein a wire assembly is provided on the outer side of the base, and a placement assembly is installed on the top of the base; The conductor assembly includes a fixed base, a rotating shaft, and a fixed plate. The fixed base is fixedly connected to the outside of the base, the rotating shaft is rotatably connected to the inside of the fixed base, one end of the fixed plate is fixedly sleeved on the outside of the rotating shaft, and a conductor ring is movably connected to the top of the other end of the fixed plate. One end of the rotating shaft extends to the top of the fixed base and is fixedly sleeved with an eccentric block. Four evenly distributed support legs are fixedly connected to the outside of the fixed base, and a fixed block is fixedly connected to one side of one of the support legs. A telescopic spring is fixedly connected between the fixed block and the fixed plate.

[0006] Preferably, the outer side of the eccentric block is provided with a rubber protrusion, and the eccentric block is located between two of the legs.

[0007] Preferably, each of the four legs is fixedly connected to a connecting seat at one top end, and a roller is connected to the inner side of the connecting seat via a shaft.

[0008] Preferably, the placement assembly includes a rotating cylinder and a support base. The rotating cylinder is rotatably connected to the top center of the base via a bearing, and the support base is fixedly sleeved on the outside of the rotating cylinder. A placement plate is installed on the top of the support base.

[0009] Preferably, the top of the support base is fixedly connected to a positioning column, and the bottom of the placement plate is provided with a positioning hole.

[0010] Preferably, the positioning hole and the positioning post are matched, and the positioning post is inserted into the positioning hole.

[0011] Preferably, a limiting post is inserted into the top of the aforementioned rotating drum, and the limiting post is threadedly connected to the inside of the rotating drum.

[0012] Preferably, each of the four legs is fitted with a foot at one bottom end, and the eccentric block abuts against the outer side of the support base.

[0013] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects: This invention involves inserting one end of a cable into the inside of a wire ring, then pulling that end of the cable to move it. The cable, through the wire ring, pulls the rotating shaft at one end of the fixed plate to rotate inside the fixed base. The telescopic spring is compressed by the force, and the rotating shaft drives one end of the eccentric block to disengage from the outside of the support base. The cable then pulls the placement plate and cable roller to rotate, thus enabling orderly cable release. When no cable is being released, the telescopic spring drives the rotating shaft at one end of the fixed plate to rotate and reset inside the fixed base, causing the eccentric block to abut against the outside of the support base. This provides a limiting brake to the placement plate, preventing the cable roller on the placement plate from continuing to rotate due to inertia, avoiding the problem of cable tangling on the cable roller, and improving the practicality of the device.

[0019] Example Please see Figure 1-5 This utility model provides a technical solution: a wire laying device for power installation, including a base 1, a wire assembly is provided on the outside of the base 1, and a placement assembly is installed on the top of the base 1.

[0020] By setting up the wire assembly, the cable roller on the placement plate 16 can be prevented from continuing to rotate due to inertia, avoiding the problem of cables becoming scattered and tangled on the cable roller, thus improving the practicality of the device. The wire assembly includes a fixed base 2, a rotating shaft 3, and a fixed plate 4. The fixed base 2 is fixedly connected to the outside of the base 1, the rotating shaft 3 is rotatably connected to the inside of the fixed base 2, one end of the fixed plate 4 is fixedly sleeved on the outside of the rotating shaft 3, and the other end of the fixed plate 4 is movably connected to the top of a wire ring 5. One end of the rotating shaft 3 extends to the top of the fixed base 2 and is fixedly sleeved with an eccentric block 6. Four evenly distributed support legs 10 are fixedly connected to the outside of the fixed base 2, and one side of one of the support legs 10 is fixedly connected to a fixed... A telescopic spring 8 is fixedly connected between the fixed block 7 and the fixed plate 4. By inserting one end of the cable into the inside of the wire ring 5 and then pulling the cable end to move it, the cable pulls the rotating shaft 3 at one end of the fixed plate 4 to rotate inside the fixed seat 2 through the wire ring 5. The telescopic spring 8 is compressed by the force, and the rotating shaft 3 drives one end of the eccentric block 6 to disengage from the outside of the support seat 14. The cable pulls the placement plate 16 and the cable roller to rotate, so that the cable can be laid out in an orderly manner. When no cable is laid out, the telescopic spring 8 drives the rotating shaft 3 at one end of the fixed plate 4 to rotate and reset inside the fixed seat 2, so that the eccentric block 6 abuts against the outside of the support seat 14, which can limit and brake the placement plate 16.

[0021] The outer side of the eccentric block 6 is provided with rubber protrusions 9. When braking, the rubber protrusions 9 on the outer side of the eccentric block 6 abut against the outer side of the support seat 14, which can increase the friction between the eccentric block 6 and the support seat 14 and ensure the braking effect of the support seat 14. The eccentric block 6 is located between two of the support legs 10.

[0022] To make pulling the cable easier, each of the four support legs 10 is fixedly connected to a connecting seat 11 at one end. The inner side of the connecting seat 11 is connected to a roller 12 via a shaft. When the cable roller is placed on the placement plate 16, the connecting seat 11 and the roller 12 support the placement plate 16, which also makes pulling the cable easier.

[0023] The placement assembly facilitates the placement of cable rollers. The placement assembly includes a rotating drum 13 and a support base 14. The rotating drum 13 is rotatably connected to the top center of the base 1 via a bearing. The support base 14 is fixedly sleeved on the outside of the rotating drum 13. A placement plate 16 is installed on the top of the support base 14. A limiting post 18 is inserted into the top of the rotating drum 13. The limiting post 18 is threaded into the inside of the rotating drum 13. When using the device, the limiting post 18 must first be rotated in the opposite direction so that one end of the limiting post 18 is disengaged from the inside of the rotating drum 13, facilitating the placement of the cable roller. At this time, the cable roller is placed on the top of the placement plate 16, and the roller is sleeved on the outside of the rotating drum 13. Then, one end of the limiting post 18 is screwed into the inside of the rotating drum 13 to prevent the cable roller from disengaging from the top of the placement plate 16 during rotation, thus limiting the cable roller.

[0024] To facilitate the disassembly and storage of the device, a positioning post 15 is fixedly connected to the top of the support base 14, and a positioning hole 17 is provided at the bottom of the placement plate 16. The positioning hole 17 matches the positioning post 15, and the positioning post 15 is inserted into the positioning hole 17. When the device needs to be stored, the placement plate 16 is removed from the support base 14, which facilitates the separate handling and storage of the device. At the same time, during installation, the placement plate 16 is placed on the outside of the rotating cylinder 13, and the positioning post 15 inserted into the positioning hole 17 can limit the placement plate 16. A foot is installed at the bottom of each of the four legs 10, and the eccentric block 6 abuts against the outside of the support base 14. The foot can support the device.

[0025] The working principle or structural principle is as follows: When using the device, the limiting post 18 must first be rotated in the opposite direction so that one end of the limiting post 18 is disengaged from the inside of the rotating drum 13, facilitating the placement of the cable roller. At this time, the cable roller is placed on top of the placement plate 16, and the roller is sleeved on the outside of the rotating drum 13. Then, one end of the limiting post 18 is screwed into the inside of the rotating drum 13 to prevent the cable roller from disengaging from the top of the placement plate 16 during rotation, thus limiting the cable roller. By inserting one end of the cable into the inside of the wire ring 5 and then pulling the cable end to move it, the cable pulls the rotating plate 4 at one end through the wire ring 5. Shaft 3 rotates inside the fixed base 2, and the telescopic spring 8 is compressed by the force. The rotating shaft 3 then drives one end of the eccentric block 6 to disengage from the outside of the support base 14. At the same time, when the fixed plate 4 cannot move, the cable pulls the placement plate 16 and the cable roller to rotate, so that the cable can be laid out in an orderly manner. When the cable does not move, the telescopic spring 8 drives the rotating shaft 3 at one end of the fixed plate 4 to rotate and reset inside the fixed base 2, so that the eccentric block 6 abuts against the outside of the support base 14, which can limit and brake the placement plate 16, preventing the cable roller on the placement plate 16 from continuing to rotate due to inertia, and avoiding the problem of the cable on the cable roller becoming scattered and tangled.
