Description

Technical Field

[0001] This utility model belongs to the field of low-voltage engineering wiring technology, and in particular relates to a low-voltage engineering wiring device. Background Technology

[0002] Low-voltage electrical engineering is a category of electrical applications. Electrical applications can be divided into two categories according to the strength of the power transmission: high-voltage and low-voltage. The electricity used in buildings and building complexes generally refers to low-voltage AC below 220V / 50Hz, which mainly provides electrical energy to people.

[0003] Existing low-voltage wiring systems cannot measure cable length. Since cable layout requires controlling cable length to ensure accurate and aesthetically pleasing routing, it is necessary to measure the cable before wiring to select the appropriate length, which increases the number of steps and reduces work efficiency.

[0004] When it is necessary to cut the wires, workers need to use other tools to do the cutting work. Moreover, after the wires are cut, they tend to retract back into the wiring device due to inertia. Therefore, a low-voltage engineering wiring device is proposed. Summary of the Invention

[0005] The purpose of this utility model is to provide a wiring device for low-voltage engineering to solve existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a low-voltage wiring device, comprising a device housing, a base plate, and two sets of fixing plates symmetrically arranged on the upper surface of the base plate. A servo motor is mounted on one side of each of the two sets of fixing plates, and a rotating shaft is rotatably connected between the two sets of fixing plates. Rollers are inserted through the circumference of the rotating shaft, and both ends of the rotating shaft pass through both sides of the fixing plates. A roller counter is mounted on one side of each of the two sets of fixing plates. A power supply is located on the upper surface of the base plate. Two sets of support plates are symmetrically arranged on the upper surface of the base plate, and a positioning roller shaft is rotatably connected between the two sets of support plates. The system is equipped with two sets of mounting plates. A first telescopic rod is symmetrically arranged on opposite surfaces of the two sets of mounting plates. An arc-shaped clamp is located at one end of each first telescopic rod. An anti-slip pad is provided on the inner wall of the arc-shaped clamp. Two sets of pull rods are arranged on the periphery of the arc-shaped clamp. A wire-cutting device is located on the upper surface of the base plate. The wire-cutting device includes an electric telescopic rod. A cutting blade is located at the output end of the electric telescopic rod. A blade holder is located inside the wire-cutting device. A wire outlet hole is opened on one side of the wire-cutting device. A support frame is located on one side of the wire-cutting device. A cleaning cylinder is inserted into the support frame. A brush is provided on the inner wall of the cleaning cylinder.

[0008] A door panel is hinged to the upper surface of the device housing, a caster wheel is provided on the bottom surface of the base plate, a control panel is provided on one side of the device housing, the caster wheel has a self-locking structure, and a push handle is provided on the upper surface of the device housing.

[0009] The power supply is electrically connected to the control panel, the roller counter, the servo motor, and the electric telescopic rod. The control panel receives and processes the signals emitted by the roller counter. One end of the rotating shaft is fixedly connected to the output end of the servo motor, and the other end of the rotating shaft is rotatably connected to the roller counter.

[0010] The first telescopic rod includes a push rod, a hollow rod, and a spring. The push rod and the hollow rod are slidably connected. The spring is sleeved on the periphery of the push rod and the hollow rod. One end of the spring is fixedly connected to one end of the push rod, and the other end of the spring is fixedly connected to one end of the hollow rod.

[0011] The servo motor drives the rotating shaft to rotate, which in turn causes the cable on the roller to start being released. The roller counter detects the number of rotations of the roller and sends a signal to the control panel. The control panel calculates the approximate length based on the circumference of the roller through a pre-set program. When the appropriate length is reached, the servo motor stops, achieving the effect of quickly releasing the target length of cable during wiring, saving the steps of measuring the cable and improving work efficiency.

[0012] This utility model has the following beneficial effects:

[0013] This invention involves winding the cable to be laid onto the surface of a roller. When laying begins, a servo motor is activated, driving a rotating shaft to release the cable from the roller. A roller counter detects the number of rotations and sends a signal to the control panel. The control panel, through a pre-programmed sequence, calculates the approximate length based on the roller's circumference. When the appropriate length is reached, the servo motor stops, achieving rapid cable release of the target length during cabling. This saves on cable measurement steps and improves work efficiency. A cutting device is also included; once the appropriate cable length is reached, an electric telescopic rod is activated, driving a cutting blade to cut the cable, achieving rapid cutting to the target length.

[0014] Meanwhile, the positioning roller can center the cable during the wiring process, avoiding friction and increasing cable loss. At the same time, it is inevitable to temporarily change the wiring position during construction, but at this time the cable surface is covered with dust. By setting a cleaning cylinder, the brush in the cleaning cylinder will clean the cable surface when the cable is retrieved.

[0015] By setting a first telescopic rod with a spring sleeved on its periphery and an arc-shaped clamp at the output end of the first telescopic rod, a pull rod is set on the periphery of the arc-shaped clamp. The cable can be inserted by pulling the pull rod and then secured by the compression of the first telescopic rod. At the same time, the anti-slip pads set on the inner wall of the arc-shaped clamp can further increase the friction between the arc-shaped clamp and the surface of the cable, thus avoiding the problem that the cable will easily retract under the action of inertia after being cut.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A rotating shaft 22 is rotatably connected between the two sets of fixing plates 21. Rollers 23 are inserted through the circumference of the rotating shaft 22. Both ends of the rotating shaft 22 pass through both sides of the fixing plates 21. A roller counter 3 is arranged on one side of each of the two sets of fixing plates 21. A power supply 4 is arranged on the upper surface of the base plate 12. Two sets of support plates 6 are symmetrically arranged on the upper surface of the base plate 12. A positioning roller shaft 61 is rotatably connected between the two sets of support plates 6. Two sets of mounting plates 7 are provided, and first telescopic rods 8 are symmetrically arranged on opposite surfaces of the two sets of mounting plates 7. An arc-shaped clamping plate 81 is provided at one end of the first telescopic rod 8, and an anti-slip pad 82 is provided on the inner wall of the arc-shaped clamping plate 81. Two sets of pull rods 83 are provided on the periphery of the arc-shaped clamping plate 81. A wire cutting device 9 is provided on the upper surface of the base plate 12. The wire cutting device 9 includes an electric telescopic rod 91, and a cutting blade 92 is provided at the output end of the electric telescopic rod 91. A blade holder 93 is provided inside the wire cutting device 9. A wire outlet hole is opened on one side of the wire cutting device 9. A support frame 10 is provided on one side of the wire cutting device 9. A cleaning cylinder 101 is inserted inside the support frame 10, and a brush 102 is provided on the inner wall of the cleaning cylinder 101.

[0028] Furthermore, a door panel is hinged to the upper surface of the device housing 1, a caster wheel 5 is provided on the bottom surface of the base plate 12, a control panel 11 is provided on one side of the device housing 1, the caster wheel 5 has a self-locking structure, and a push handle is provided on the upper surface of the device housing 1.

[0029] Furthermore, the power supply 4 is electrically connected to the control panel 11, the roller counter 3, the servo motor 2, and the electric telescopic rod 91. The control panel 11 receives and processes the signals emitted by the roller counter 3. One end of the rotating shaft 22 is fixedly connected to the output end of the servo motor 2, and the other end of the rotating shaft 22 is rotatably connected to the roller counter 3.

[0030] Furthermore, the first telescopic rod 8 includes a push rod, a hollow rod, and a spring. The push rod and the hollow rod are slidably connected. The spring is sleeved on the periphery of the push rod and the hollow rod. One end of the spring is fixedly connected to one end of the push rod, and the other end of the spring is fixedly connected to one end of the hollow rod.

[0031] Furthermore, servo motor 2 drives rotating shaft 22 to rotate, and rotating shaft 22 drives the cable on roller 23 to start being released. Roller counter 3 detects the number of revolutions of roller 23 and sends a signal to control panel 11.

When the appropriate length is released, servo motor 2 stops, achieving the effect of quickly releasing the target length of cable during wiring, saving the steps of measuring the cable, and improving work efficiency.

[0032] It should be noted that this utility model involves winding the cable to be laid around the surface of the roller 23. When laying begins, the servo motor 2 is started, which drives the rotating shaft 22 to rotate. The rotating shaft 22 then causes the cable on the roller 23 to be released. The roller counter 3 detects the number of rotations of the roller 23 and sends a signal to the control panel 11.

[0033] Meanwhile, during the wiring process, the positioning roller 61 can center the cable and avoid friction that increases cable loss. At the same time, it is inevitable to temporarily change the wiring position during construction, but at this time the cable surface is covered with dust. By setting up the cleaning cylinder 101, the brush 102 inside the cleaning cylinder 101 will clean the cable surface when the cable is recycled.

[0034] By setting a first telescopic rod 8, with springs sleeved on its circumference, and an arc-shaped clamping plate 81 at the output end of the first telescopic rod 8, and a pull rod 83 on its circumference, the cable can be inserted by pulling the pull rod 83 and then secured by the compression of the first telescopic rod 8. At the same time, the anti-slip pads 82 on the inner wall of the arc-shaped clamping plate 81 can further increase the friction between the arc-shaped clamping plate 81 and the surface of the cable, avoiding the problem that the cable will easily retract under the action of inertia after being cut.
