[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0025] A standardized, single-person-operable wire-feeding device, such as... Figures 1 to 4 As shown, it includes a main frame 1, an n-shaped frame 2, a wire fixing plate 3, a wire fixing ring 4, a wire fixing hole 5, a through joint 6, an elastic line 7, an ink cartridge 8, and a handle 9.
[0026] like Figure 5 As shown, the main frame 1 includes a U-shaped main rod 101, and bent connecting rods 102 are connected to both ends of the U-shaped main rod 101.
[0027] The main frame 1 has symmetrical n-shaped frames 2 at both ends, and the bent connecting rod 102 is fixedly connected to the lower end of the side rod of the n-shaped frame 2.
[0028] The inner side of the n-shaped frame 2 is fixed with a wire fixing plate 3 and the outer side is bent with a wire fixing ring 4. The wire fixing plate 3 has a wire fixing hole 5. The side wall of the wire fixing plate 3 has a through joint 6 that communicates with the wire fixing hole 5. An elastic wire 7 is installed between the wire fixing holes 5 of the wire fixing plate 3. The two ends of the elastic wire 7 are fixed to the wire fixing ring 4. One end of the elastic wire 7 is threaded through an ink cartridge 8. The ink cartridge 8 is located at the lower end of one of the n-shaped frames 2.
[0029] A handle 9 is provided in the middle of the U-shaped main rod 101.
[0030] Both the main frame 1 and the n-shaped frame 2 are made of φ4 high-strength steel bars.
[0031] The main frame 1 is 500mm long; the n-shaped frame 2 is 100mm long and 30mm high.
[0032] The bending connecting rod 102 is 100mm long, with bends at 80mm above and 20mm below, and the horizontal section of the bend is 50mm long.
[0033] The radius of the fixed ring 4 is 5mm.
[0034] The dimensions of the cable tray 3 are 10mm × 10mm × 1.5mm.
[0035] The radius of the wire fixing hole 5 is 0.25mm.
[0036] The width of seam 6 is 0.2mm.
[0037] The wire fixing plate 3 is made of steel sheet. The steel sheet is cut at an angle of 45 degrees upward from the wire fixing hole 5 to the edge of the steel sheet to form a through joint 6. The wire fixing hole 5 and the through joint 6 are sufficient to allow the wire to pass through.
[0038] The four corners of the wire fixing plate 3 are provided with rounded chamfers.
[0039] The elastic line 7 uses the standard white thread commonly used for elastic lines.
[0040] The ink cartridge 8 uses a plastic bottle with a cap. There is a hole near the bottom of the bottle, the size of which is just enough to thread a wire. Toner is added inside.
[0041] Handle 9: Weld steel bars on-site or purchase ready-made stainless steel handles, the size of which is suitable for an adult male to hold with one hand.
[0042] To ensure user experience and safety, all right-angled and sharp parts are curved with an radius of 5mm to effectively prevent scratches during use.
[0043] The materials, specifications, and dimensions listed above can be adjusted according to actual circumstances and are not fixed. However, all must be designed to ensure safe use after processing and manufacturing.
[0044] On-site implementation:
[0045] Step 1: Infrared positioning preparation:
[0046] Set up the infrared level device stably, turn it on and adjust it to level, and accurately project the horizontal and vertical lines onto the areas where the lines need to be laid.
[0047] Step 2: Preparing to inscribe the elastic line 7:
[0048] Add toner to cartridge 8 in advance, pull the elastic line 7 in the fixed hole 5 out from the seam 6, and slide cartridge 8 along the elastic line 7 from right to left. If the color is light, slide it back and forth several times to apply ink to the elastic line 7. After applying ink, put cartridge 8 back on the elastic line 7 below the n-shaped frame 2.
[0049] Step 3: Placement of the wire feeding device:
[0050] Hold handle 9, place the processed device on the wall / board, and align the inked elastic line 7 with the horizontal / vertical line to be drawn.
[0051] Step 4: Marking the lines:
[0052] Grip handle 9 firmly with one hand and apply slight pressure to ensure the device does not move easily. Pull the elastic line 7 up about 2cm from the middle with the other hand, then release the elastic line 7. The line release is complete. If the line distance is long, the device can be moved multiple times, and the above steps can be repeated to complete the line release.
[0053] Step 5: Remove the device and repeat the above steps to lay the wire at the next section where wire needs to be laid.
