Description
Technical field
The utility model relates to a kind of test pencil, specifically a kind of safe bent test pencil.
Background technology
Test pencil is a kind of electrician tool, whether be chargedly used in test wires, the test pencil of prior art only has measuring voltage function usually, on-off function and miniature straight screwdriver 3 kinds of functions, and electrician is in routine inspection and simple maintenance debugging efforts, often also need to use screwdriver, small flashlight, electrician's knife, the instruments such as lettering pen, in routine work, often come and go working site because leaving behind certain instrument above, make troubles to work, special in high-altitude and operation in narrow space, use multiple types of tools that inconvenience can be caused to put and carry, sometimes also to drop generation casualty accident because of instrument high-altitude, existing test pencil contact can not bend, and the object sometimes will measured in turning is very inconvenient, the general principle of test pencil is that detection end touching is by measuring point, operating personnel grips hand-held housing, touch is exposed on the end face of handheld housing body afterbody outside test pencil bar simultaneously, take human body as earth conductor, after forming loop, indicator indicates according to conduction situation, but, be that earth conductor also exists potential safety hazard, if false touch high-voltage charged body with human body, to electric shock accidents be caused, jeopardize personal safety, for above problem, need to propose new technical scheme.
Utility model content
The purpose of this utility model is to provide a kind of structure simple, use safety, and contact part can bending, and it is more convenient to measure; Have the bent test pencil of the safety of test pencil, lettering pen, torch and electrician's knife function concurrently, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A safe bent test pencil, comprises housing, and described housing forward end is provided with contact, and described contact comprises copper wire bundle conductor wire, and one end of copper wire bundle conductor wire is connected with measurement electronic component, and the other end stretches out housing and is coated with carbon fiber high tenacity insulating materials; Described housing forward end is provided with annular LED lamp, and housing front is provided with display, indicator lamp and LED switch; Described back side of shell is provided with the blade support of band blade chute, blade holder is provided with in blade chute, described blade holder is provided with the blade of band fixing hole, and blade holder slides setting in blade chute, and blade holder is flexibly connected with blade chute; Described housing afterbody is connected with conduction foot piece, and conduction one end of foot piece is fixedly connected with the afterbody of housing, and the other end wriggles and extends to free end, and free end end is exposed wire, and conduction foot piece mid portion is coated with insulating outer layer; Described housing side is provided with storage trough, and opposite side is provided with lettering pen.
As further program of the utility model: the nib of described lettering pen is contrary with the sensing of contact, the end of lettering pen is provided with battery case, is placed with dry cell in battery case.
As the utility model further scheme: described display comprises voltage display and temperature indicator, described voltage display and temperature indicator are noctilucence display.
As the utility model further scheme: be placed with backup electrode and luminous tube in described storage trough.
As the utility model further scheme: the electrical connection of described LED switch, annular LED lamp, display, indicator lamp and measurement electronic component is all electrically connected with the dry cell in battery case.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, and the carbon fiber high tenacity insulating materials that contact part is arranged and copper wire bundle conductor wire have toughness, flexible, conveniently the electronic device of some corners is measured; Annular LED lamp energy convenient operation personnel work under dim environment, and display screen adopts noctilucence material, energy convenient operation personnel reading under dark surrounds and strong light environment; Housing afterbody has additional conduction foot piece, operating personnel only by natural low potential objects such as conduction foot piece contact bodies of wall, need make power supply, test pencil, body of wall form galvanic circle, can either effectively measure, electric current can be avoided again by human body, thus ensure the safety of operator; Lettering pen, ring-type LED group and electrician's knife are combined with test pencil bulk junction cleverly, the utility model is made to have the function of lettering pen torch, electrician's knife and test pencil concurrently, lettering pen in use facilitates the timely record of staff, can change in time when the backup electrode placed in storage trough and luminous tube are convenient to break down, to save time and laborsaving.
