Description
Technical Field
[0001] This invention relates to the field of power system conductor installation, and more specifically, to a portable safety construction tool that integrates insulated wire harness fixing and lighting. Background Technology
[0002] In current power systems, the wiring connections for devices such as electricity meters and switches typically use a fixed sequence of multiple wires as a group. However, in actual construction work, such as equipment replacement and maintenance, the following problems exist: The wire sequence is prone to error; manual operation can easily reverse the wire sequence, leading to reverse metering, incorrect phase sequence, and other problems, causing economic disputes between users and power supply companies; there is a risk of wire strand cross-strands, as multi-strand or flexible wires are prone to cross-stranding during operation, causing short circuits and arc discharges, seriously threatening the safety of workers; construction efficiency is low, as traditional tools are difficult to use quickly to secure wire bundles in confined spaces or at night, and the lack of precise lighting further prolongs the work time; and there are numerous safety hazards, as issues such as wire bundle swaying or lack of compaction can cause wires to detach, leading to equipment failure or electric shock accidents. These problems urgently require an integrated and intelligent construction tool to improve safety, efficiency, and ease of operation. Summary of the Invention
[0003] To address the problems existing in the prior art, the purpose of this invention is to provide a portable safety construction tool that integrates insulated wire harness fixing and lighting. It can securely fix the wire harness through limiting devices, and improve the convenience of wire harness installation by controlling all limiting devices with one hand through a pull rod. Furthermore, the expander can adjust individual limiting devices, increasing the flexibility of the device in fixing the wire harness.
[0004] To solve the above problems, the present invention adopts the following technical solution.
[0005] A portable safety construction tool integrating insulated wire harness fixing and lighting includes a handle, two brackets are installed on the side of the handle, and a hollow shell is installed at the end of the two brackets away from the handle. Multiple limiting devices are installed in the middle of the hollow shell, and a first crossbar and a second crossbar are slidably connected in the middle of the hollow shell. The first crossbar has multiple first sliding holes in its middle section, and a first transmission rod is hinged to the end of the first crossbar near the grip. The second crossbar has multiple second sliding holes in its middle section, and a second transmission rod is hinged to the end of the second sliding hole near the grip. A support block is hinged to the ends of the first and second transmission rods near the grip. The first and second crossbars are distributed in upper and lower layers in the middle of the hollow shell. A spring telescopic rod is installed at one end of the two brackets that are close to each other. A top block is installed at the end of the spring telescopic rod. A connecting rod is installed between the two top blocks. A pull rod is installed at the end of the connecting rod that is close to the handle. Hooks are rotatably connected to both ends of the pull rod. The limiting device includes a column installed in the middle of a hollow shell. A first clamping plate and a second clamping plate are rotatably connected to the outer end of the column. A first locking rod is installed at the upper end of the first clamping plate, and a second locking rod is installed at the lower end of the second clamping plate. A pressure plate is installed at the end of the first and second clamping plates away from the first locking rod. An arc-shaped plate is installed at the end of the pressure plate away from the first and second clamping plates. A slot is formed at the end of the two pressure plates that are close to each other. A through hole is formed in the middle of the support rod below the two slots. The first locking rod slides inside the first sliding hole, and the second locking rod slides inside the second sliding hole. The limiting device securely fixes the wire harness, and the pull rod allows for one-handed control of all limiting devices, improving the convenience of wire harness installation. Furthermore, the expander can adjust individual limiting devices, increasing the flexibility of the device in fixing the wire harness.
[0006] Furthermore, a support rod is installed at the outer end of the column, and a retaining ring is installed at the end of the support rod, so that the wire harness can be pre-locked in the retaining ring, which facilitates the pre-fixation of the wire harness.
[0007] Furthermore, an insulating sheet is installed on the upper end of the arc-shaped plate, and the column is located in the middle of the hollow shell, so that the wire harness can be fixed with the assistance of the insulating sheet, and the limiting device can be fixed through the column.
[0008] Furthermore, the first crossbar and the first transmission rod are hinged together by a first hinge, and the second crossbar and the second transmission rod are hinged together by a second hinge, so that the first transmission rod can drive the first crossbar to move through the first hinge, and the second transmission rod can drive the second crossbar to move through the second hinge.
[0009] Furthermore, the spring telescopic rod includes a housing, a push rod is slidably connected to the middle of one end of the housing, and a compression spring is placed in the middle of the housing, so that the spring telescopic rod can drive the pull rod to move away from the gripping rod through the top block, thereby enabling the limiting device to perform a clamping operation on the wire harness.
[0010] Furthermore, an expander is detachably connected to the outside of the hollow shell. The expander includes a rotating rod with a knob installed at the upper end and an elliptical block installed at the outer end. A baffle is installed at the outer end of the rotating rod below the elliptical block, so that the two pressure plates can be separated to both sides by the expander, thereby temporarily freeing the single wire harness from the control of the limiting device.
[0011] Furthermore, the diameter of the baffle is larger than the diameter of the through hole, and the elliptical block can be inserted into the middle of the slot, so that the expander can be engaged in the middle of the through hole, and the elliptical block can limit the expander by being engaged in the middle of the slot.
[0012] Furthermore, the distance between the two slots is between the lengths of the major and minor axes of the elliptical block, allowing the elliptical block to enter between the two slots, and the elliptical block can rotate to move the two pressure plates to the sides.
[0013] Furthermore, two annular protrusions are provided at the outer end of the column, and the two annular protrusions are located on the upper and lower sides of the first clamping plate and the second clamping plate, respectively. An LED light source is installed at the end of the hollow shell away from the bracket, so that the first clamping plate and the second clamping plate are not easily displaced, and the device can be illuminated by the light source when the wire harness is limited.
[0014] Compared with the prior art, the advantages of this invention are: (1) Improve the convenience of wire harness fixing: Enables one-handed operation. By pulling the lever at the handle, the opening and closing of the clamps of all limit devices can be controlled simultaneously without individual adjustment, greatly simplifying the fixing process. Equipped with a snap ring structure, the wire harness can be pre-fixed in the snap ring to avoid wire harness displacement during construction and further reduce the difficulty of operation.
[0015] (2) Enhanced operational flexibility: Supports independent adjustment of a single wire harness. With the help of an expander, the clamps of the specified limit device can be opened to temporarily remove the single wire harness from control, making it convenient to make local adjustments or replacements to the wire harness. The clamp spacing of the limit device can be adaptive through structural linkage, which can adapt to wire harnesses of different specifications without the need for frequent tool or accessory replacements.
[0016] (3) Ensure construction safety: It has insulation protection function. The arc plate of the limit device is equipped with an insulating sheet, which can effectively isolate the wire harness and the metal parts of the tool and reduce the risk of electric shock. It integrates lighting function. The hollow shell end is equipped with an LED light source, which can provide lighting in the dim construction environment and avoid operational errors or safety hazards caused by poor vision.

[0022] Example 1 This embodiment illustrates the structure of the device and its beneficial effects: Please see Figure 1-11 A portable safety construction tool integrating insulated wire harness fixing and lighting includes a handle 1, two brackets 2 are installed on the side of the handle 1, a hollow shell 3 is installed at the end of the two brackets away from the handle 1, multiple limiting devices 4 are installed in the middle of the hollow shell 3, and a first crossbar 5 and a second crossbar 9 are slidably connected in the middle of the hollow shell 3. The first crossbar 5 has multiple first sliding holes 6 in the middle, and the first transmission rod 8 is hinged to the end of the first crossbar 5 near the grip rod 1. The second crossbar 9 has multiple second sliding holes 10 in the middle, and the second transmission rod 12 is hinged to the end of the second sliding hole 10 near the grip rod 1. The first transmission rod 8 and the second transmission rod 12 are hinged to the end of the grip rod 1. The support block 13 is hinged to the end of the first transmission rod 8 and the second transmission rod 12 near the grip rod 1. Two supports 2 are fitted with spring telescopic rods 14 at their close ends. A top block 15 is fitted at the end of the spring telescopic rod 14. A connecting rod 16 is fitted between the two top blocks 15. A pull rod 17 is fitted at the end of the connecting rod 16 that is close to the handle 1. Hooks 18 are rotatably connected to both ends of the pull rod 17. An expander 19 is detachably connected to the outside of the hollow shell 3. The limiting device 4 includes a column 401, with a first clamping plate 402 and a second clamping plate 412 rotatably connected to the outer end of the column 401. A first locking rod 406 is installed on the upper end of the first clamping plate 402, and a second locking rod 407 is installed on the lower end of the second clamping plate 412. A pressure plate 408 is installed on the end of the first clamping plate 402 and the second clamping plate 412 away from the first locking rod 406. An arc-shaped plate 410 is installed on the end of the pressure plate 408 away from the first clamping plate 402 and the second clamping plate 412. A slot 409 is opened at the end of the two pressure plates 408 that are close to each other. A through hole 405 is opened in the middle of the support rod 403 located below the two slots 409.
[0023] Please see Figure 3-5A support rod 403 is installed at the outer end of the column 401, and a retaining ring 404 is installed at the end of the support rod 403, so that the wire harness can be pre-locked in the retaining ring 404 for pre-fixation of the wire harness. The first retaining rod 406 corresponds to the first sliding hole 6, and the second retaining rod 407 corresponds to the second sliding hole 10, so that the first crossbar 5 can drive the first retaining rod 406 to move through the first sliding hole 6, and the second crossbar 9 can drive the second retaining rod 407 to move through the second sliding hole 10. An insulating sheet 411 is installed on the upper end of the arc plate 410, and the column 401 is located in the middle of the hollow shell 3, so that the wire harness can be fixed with the assistance of the insulating sheet 411, and the limiting device 4 can be fixed through the column 401.
[0024] Please see Figure 3-7 The first crossbar 5 and the first transmission rod 8 are hinged together by the first hinge 7, and the second crossbar 9 and the second transmission rod 12 are hinged together by the second hinge 11. This allows the first transmission rod 8 to drive the first crossbar 5 to move via the first hinge 7, and the second transmission rod 12 to drive the second crossbar 9 to move via the second hinge 11. The spring telescopic rod 14 includes a housing 1401. A push rod 1402 is slidably connected to the middle of one end of the housing 1401, and a compression spring 1403 is placed in the middle of the housing 1401. This allows the spring telescopic rod 14 to drive the pull rod 17 to move away from the grip rod 1 via the top block 15, thereby enabling the limiting device 4 to clamp the wire harness.
[0025] Please see Figure 3-8 The expander 19 includes a rotating rod 1901, with a knob 1902 mounted on its upper end. An elliptical block 1903 is mounted on the outer end of the rotating rod 1901, and a baffle 1904 is mounted on the outer end of the rotating rod 1901 below the elliptical block 1903. This allows the two pressure plates 408 to be separated to both sides by the expander 19, thereby temporarily freeing a single wire harness from the control of the limiting device 4. The diameter of the baffle 1904 is larger than the diameter of the through hole 405, and the elliptical block 1903 can be engaged in the middle of the slot 409, allowing the expander 19 to be engaged in the middle of the through hole 405. The elliptical block 1903 can limit the expander 19 by engaging in the middle of the slot 409. The distance between the two slots 409 is between the major and minor axes of the elliptical block 1903, allowing the elliptical block 1903 to enter between the two slots 409. The elliptical block 1903 can also rotate to move the two pressure plates 408 to the sides. Two annular protrusions are provided at the outer end of the column 401, located on the upper and lower sides of the first clamping plate 402 and the second clamping plate 412, respectively. An LED light source is installed at the end of the hollow shell 3 away from the bracket 2, preventing the first clamping plate 402 and the second clamping plate 412 from shifting, and ensuring the device is illuminated when limiting the wire harness.
[0026] Example 2 This embodiment illustrates the working principle of the device: When installing wire harnesses in a power system, select a suitable arc plate 410 according to the wire harness size. Hold the handle 1 and pull rod 17 with one hand, bringing them close together. Rotate the hook 18 so that it hooks onto the outside of the handle 1. At this time, the pull rod 17 is limited by the hook 18, and no external force needs to be applied to the pull rod 17. During the movement of the pull rod 17 towards the handle 1, the pull rod 17 drives the support block 13 to move through the connecting rod 16. The support block 13 drives the hinged first transmission rod 8 and second transmission rod 1. 2. Movement: The first transmission rod 8 drives the first crossbar 5 to move laterally, and at the same time, the second transmission rod 12 drives the second crossbar 9 to move laterally. The first crossbar 5 drives the first locking rod 406 to move through the first sliding hole 6, and the second crossbar 9 drives the second locking rod 407 to move through the second sliding hole 10, so that the first clamping plate 402 and the second clamping plate 412 open, the two pressure plates 408 move away from each other, so that the two arc plates 410 separate, and all the wire harnesses to be installed are respectively inserted into the middle of the retaining ring 404 for pre-fixation; Remove the hook 18 from the outside of the grip 1. Under the action of the spring telescopic rod 14, the pull rod 17 moves away from the grip 1. At this time, the first transmission rod 8 and the second transmission rod 12 drive the first crossbar 5 and the second crossbar 9 to move in the same direction, so that the first clamping plate 402 and the second clamping plate 412 close. At this time, the two pressure plates 408 drive the two arc plates 410 to clamp and limit the wire harness, while the insulating sheet 411 provides auxiliary limit for the wire harness. When a single wire harness needs to be adjusted independently, the expander 19 is removed from the hollow housing 3, the rotating rod 1901 is inserted into the middle of the through hole 405, and the elliptical block 1903 and the two slots 409 are positioned at the same height by the baffle 1904. The knob 1902 is rotated so that the two ends of the long axis of the elliptical block 1903 are inserted into the middle of the slot 409. At this time, the two pressure plates 408 are deformed by the elliptical block 1903, so that the two arc plates 410 no longer limit the wire harness. The wire harness is then adjusted. After the wire harness is adjusted, the expander 19 is removed from the middle of the through hole 405, the pressure plates 408 are reset, and the arc plates 410 limit the wire harness again. When the ambient light is low, the LED light source is turned on to illuminate the work area. The wire harness can be securely fixed by the limiting device 4, and all limiting devices 4 can be controlled with one hand by the pull rod 17, which improves the convenience of wire harness installation. Furthermore, the expander 19 can adjust individual limiting devices 4, increasing the flexibility of the device in fixing the wire harness.
[0027] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
