In addition, electrical instruments are usually installed in electrical cabinets or at higher positions. The structure in the comparative literature needs to be placed on the ground for use, which is not conducive to convenient operation by the operator.

[0006] In order to solve the above problems, an auxiliary wiring device for installing an electrical instrument is proposed. Utility Model Content

[0029] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0030] like Figure 1-Figure 5 As shown, the present embodiment provides an auxiliary wiring device for installing an electrical instrument, comprising a base plate 1, suction cup foot pads 2 are threadedly installed at the four corners of the bottom of the base plate 1, a telescopic support column 3 is threadedly installed at the top of the base plate 1, an inclined support frame 6 is welded and fixed to the top of the telescopic end of the telescopic support column 3, a top plate 7 is fixed to the top of the inclined support frame 6 through a slot, a supporting vertical plate 8 is welded on the top plate 7, a stripping mechanism 9 is arranged on the supporting vertical plate 8; the stripping mechanism 9 comprises a rotating disk 901 which is fixed to the top of the supporting vertical plate 8 for limited rotation, a threading hole 908 is opened in the center of the rotating disk 901, and two symmetrical holes are opened on the bottom of the rotating disk 901 There is a guide groove 911, in which a blade holder 905 is slidably arranged, and an arc blade 909 is embedded on the blade holder 905; the outer sides of the blade holder 905 are internally threadedly connected with a bidirectional threaded screw 906, one end of the bidirectional threaded screw 906 is provided with a circuit integrated board 11, and a return line is provided inside the circuit integrated board 11. The return line passes through the blade holder 905 and is electrically connected to the two groups of arc blades 909 respectively. The arc blades 909 are made of conductive material, and the bidirectional threaded screw 906 is rotatably installed on the bottom of the rotating disk 901 through a hanging plate, and the circuit integrated board 11 is located on one side of the outer wall of one group of hanging plates.

[0031] In the above structure, the suction cup foot pad 2 can be stabilized on the side of the operator's body by stepping on it, or fixed inside the electrical cabinet, in a position convenient for operation; the bidirectional threaded screw 906 carries a blade machine that can flexibly adjust the position to adapt to cables of different sizes. After the arc blade 909 cuts off the cable sheath and contacts the copper core, it connects the loop line. The loop current signal is detected by the current sensor in the controller and stops the control unit, immediately stopping the skin cutting motor 910 to avoid damage to the copper core. Compared with traditional wire strippers, which are not accurately operated by manual labor and are easy to damage the copper core, the structure of this device has the function of protecting the cable.

[0032] A controller 4 is detachably mounted on one side of the outer wall of the telescopic support column 3. The controller 4 has a built-in battery. A control line group 5 is led out from the top of the controller 4. The controller 4 is a PLC programmable type controller 4. The controller 4 can start the electrical equipment according to the setting based on the trigger signal.

[0033] The control line group 5 is connected to the internal lines of the circuit integrated board 11. In addition to the loop line, the circuit integrated board 11 also encapsulates other lines such as the power supply line, signal line and control line in the control line group 5. The controller 4 applies a weak current to the loop line, and the loop line has a load inside the controller 4, which has a safety protection function, and the conducted current will not cause harm to the human body.

[0034] A transmission assembly 912 is nested at the other end of the bidirectional threaded screw 906. The transmission assembly 912 consists of a pulley and a belt. A skin cutting motor 910 is installed on the outside of one of the pulleys. After being driven by the belt, the bidirectional threaded screw 906 can rotate synchronously. The skin cutting motor 910 is electrically connected to the control line group 5. The skin cutting motor 910 is located on the outer wall side of another group of hanging plates.

[0035] A driving tooth groove 902 is formed on the outer wall of the rotating disk 901, and a driving gear 903 is meshed on the outside of the driving tooth groove 902. A circular cutting motor 904 is connected to the bottom of the driving gear 903 through an axis. The circular cutting motor 904 is electrically connected to the control line group 5. The circular cutting motor 904 is controlled by the controller 4 and can only drive the rotating disk 901 to rotate 180° to prevent the line from winding. After rotating 180°, the circular cutting motor 904 reverses and resets the rotating disk 901.

[0036] The circular cutting motor 904 is detachably fixed on the top plate 7 , and a center hole aligned with the threading hole 908 is opened in the inner wall of the top plate 7 .

[0037] A hollow cylinder 10 arranged around the central hole is fixed at the bottom of the top plate 7, and a switch button 907 is also arranged on the top of the rotating disk 901. The switch button 907 is connected to the control line group 5, and the operation of the skin cutting motor 910 is controlled by the controller 4.

[0038] The working principle of the device: When the device is in use, the controller 4 is powered by a battery.

[0039] According to the position of the electrical instrument, the height of the peeling mechanism 9 is adjusted by the telescopic support column 3 so that it is located at a height that is convenient for the user to operate. The bottom is fixed to the ground by the suction cup foot pad 2 to maintain the stability of the device operation.

[0040] The wire to be stripped is inserted into the threading hole 908, and the position of the wire stripping is located between the arc blades 909. The other fingers of the same hand or another hand press the switch button 907 to notify the controller 4 to start the skin cutting motor 910 to drive the bidirectional threaded screw 906 to rotate. The two sets of blade holders 905 carry the arc blades 909 to move towards each other and cut into the cable. After the arc blades 909 contact the copper core, the internal circuit line of the circuit integrated board 11 is connected, and the loop current signal is transmitted to the monitor in the controller 4. The monitor notifies the controller 4 to stop the skin cutting motor 910 and start the circular cutting motor 904 at the same time. The circular cutting motor 904 cuts 180° along the outer wall of the cable. The two arc blades 909 disconnect the cable outer skin, and then the circular cutting motor 904 drives the arc blade 909 to reset. The operator pulls out the cable upward through the tripping effect of the arc blade 909 to separate the broken skin. When using it again, press the switch button 907 to start the skin cutting motor 910 to adjust the opening of the arc blade 909 to adapt to the cutting of different cables.

[0041] When the above structure is adopted, there is no need to place the stripping device back and forth, which reduces the operation steps, improves the wiring efficiency, and does not require manual rotation of the stripping device. The operating position is adjustable, which is convenient for the operator's actual operation, reduces the need to bend down, and saves physical strength.

[0042] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
