Description

Technical Field

[0001] The utility model belongs to the technical field of leakage, and in particular relates to an electrical maintenance leakage detection device. Background Art

[0002] Electricity has become an indispensable energy source for our lives. "Leakage" is caused by a certain potential difference between the electrical appliance casing and the live wire of the mains and the ground after they are connected for some reason. The best way to detect leakage is to touch the charged body with a test pen. If the neon bulb lights up and then goes out immediately, it proves that the charged body carries static electricity. If it stays on for a long time, it is definitely a leakage.

[0003] At present, electric pens are mainly divided into pen type and screwdriver type. Compared with the pen type electric pens, the screwdriver type electric pens can not only detect the on-off status of the circuit to help electricians to troubleshoot circuit faults, but also be used as a screwdriver to repair electrical appliances. However, the flat-blade screw head and the rotating rod connected thereto of the screwdriver type electric pens in the prior art have a simple structure. When repairing electrical appliances, they can only turn the flat-blade screws, and the function is relatively simple. Utility Model Content

DETAILED DESCRIPTION

[0026] The utility model will now be described in further detail with reference to the accompanying drawings.

[0027] like Figure 1-7 , an electrical maintenance leakage detection device, comprising a handle 1, the handle 1 is an engineering plastic transparent handle 1, a metal conductive tube 6, a current sensing neon bulb 5 and a metal spring 7 are sequentially slid inwardly inserted into the inner cavity of the handle 1, a pure copper sensing pen cap 3 is arranged on the top of the metal spring 7, the conductive tube 6 and the lower end of the current sensing neon bulb 5 are in contact and connected, the upper end of the current sensing neon bulb 5 and the lower end of the metal spring 7 are squeezed and contacted, and the upper end of the metal spring 7 is squeezed and contacted and installed on the lower end of the sensing pen cap 3, that is, the metal conductive tube 6, the current sensing neon bulb 5 and the metal spring 7 are sequentially connected and can conduct electricity. The metal spring 7 in the present application is in a compressed state, and the current sensing neon bulb 5 and the conductive tube 6 are pushed by their own elastic force to be stably squeezed and installed in the inner cavity of the handle 1.

[0028] The induction pen cap 3 is threadedly installed on the top of the rotary handle 1. A slotted screw groove is arranged on the upper end of the induction pen cap 3 in this embodiment. The induction pen cap 3 is used for conducting electricity. An induction pen holder 2 is arranged between the top of the rotary handle 1 and the induction pen cap 3. A detachable rotary rod 4 is inserted and pulled out at the end of the rotary handle 1. A spiral spring metal cover 8 is fixedly installed on the lower end opening of the conductive tube 6. The conductive tube 6 and the spiral spring metal cover 8 are elastically clamped between the rotary rod 4 and the current sensing neon bulb 5. The spiral spring metal cover 8 is in a plane state in a natural state without force. When the multifunctional rotary rod 4 is inserted from below, the upper end of the multifunctional rotary rod 4 is inserted into the lower end inner cavity of the conductive tube 6, thereby pushing the center of the spiral spring metal cover 8 to protrude upward, thereby connecting the circuit between the conductive tube 6 and the multifunctional rotary rod 4.

[0029] In this embodiment, the rotating rod 4 includes a slotted screw head 46, which is fixedly mounted on one end of the rotating rod 4. The rotating rod 4 also includes a cross screw head 45 or a metal tube 50 or a cutter 48. Figure 5-7The cross screw head 45, the metal tube 50, and the cutter 48 are all made of conductive metal, which can assist in detecting the on-off status of the circuit and help electricians to troubleshoot circuit faults. On this basis, the cross screw head 45 can also turn the cross screw. A metal pen core 47 is embedded in the metal tube 50, which can also help electricians record or mark the detection status. The cutter 48 can assist electricians in prying open the outer casing of the electrical appliance or cutting the wire. An inner arc cutting blade 49 is also provided on one side of the end of the cutter 48. The inner arc cutting blade 49 is used to assist electricians in stripping the outer skin of the wire. The cross screw head 45 or the metal tube 50 or the cutter 48 is fixedly installed at the other end.

[0030] In this embodiment, a regular hexagonal column 41 is coaxially fixedly installed on the periphery of the rotating rod 4, and an inner hexagonal column groove that is interlocked with the regular hexagonal column 41 is provided at the end of the rotating handle 1. The regular hexagonal column 41 is arranged in the inner hexagonal column groove. The regular hexagonal column 41 is made of low-elasticity rubber. The low-elasticity rubber can ensure that there is sufficient friction between the regular hexagonal column 41 and the inner wall of the inner hexagonal column groove in the regular hexagonal column 41, so that the detachable multifunctional rotating rod 4 can be stably installed in the inner hexagonal column groove, and fixing blocks 42 are fixedly installed at both ends of the regular hexagonal column 41.

[0031] A plurality of anti-skid patterns 43 and annular grooves 44 are provided on the outer wall of the fixing block 42. The plurality of anti-skid patterns 43 and annular grooves 44 are mainly used to make the outer wall of the fixing block 42 rough, which is conducive to pulling the rotating rod 4 out of the inner hexagonal column groove. When the regular hexagonal column 41 in the rotating rod 4 is inserted into the inner hexagonal column groove, the slotted screw head 46 or the cross screw head 45 or the metal tube 50 or the cutter 48 at the top of the rotating rod 4 will be inserted into the conductive tube 6 and squeezed into contact with the spiral spring metal cover 8. One fixing block 42 is stuck in the rotating handle 1, and the other fixing block 42 is arranged on the outside of the rotating handle 1.

[0032] The utility model fixes two slotted screw heads 46 or cross screw heads 45 or metal tubes 50 or cutters 48 with different functions at both ends of the rotary rod 4, so that the rotary rod 4 has the functions of screwing the slotted screws or cross screws or recording, marking or cutting, opening the housing of an electrical appliance, and stripping wires in addition to the original conductive function, thereby increasing the use of the electric pen.

[0033] Embodiment 2:

The inner hexagonal cartridge 9 is inserted into the inner ring of the metal spring 7. A metal pen core 10 is installed in the inner hexagonal cartridge 9 for plugging and unplugging, so that the electric pen has the function of recording and marking.
