Description
Technical field
The utility model relates to a kind of pointer multimeter, is specifically related to a kind of waterproof construction applied on pointer multimeter.
Background technology
Pointer multimeter is aesthetic in appearance generous, low price, measure range extensively, use simple, easy to carry, obtain the generally use of country facilities, unit, school and individual.Be applicable to the use of the field measurements such as electrician, electric equipment, electronic device, the requisite survey instrument of electric appliances service industry especially, be also applicable to the use of school's relevant speciality as teaching.
At present, pointer multimeter is hard plastic case, and crash resistance can be very poor, easily breaks; Nor there is protection against the tide, water resistance, easily make moist, and dust easily enters multimeter inside, affect the normal use of multimeter, shorten the serviceable life of multimeter.
Utility model content
The purpose of this utility model is to provide a kind of pointer multimeter, has waterproof, shatter-resistant and resist to fall function, thus ensures the stable performance of multimeter, increases the service life.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of pointer multimeter, comprises gauge outfit, switch, circuit board and watchcase, and described watchcase comprises front watchcase and rear watchcase; Described front watchcase adopts PC rigid plastic one-body molded; Described rear watchcase is provided with the waterproof construction with the surrounding edge interference fit of described front watchcase, and described waterproof construction comprises the periphery sides and interior surrounding edge made by TPU flexible glue, and the surrounding edge of described front watchcase embeds in the gap between described periphery sides and interior surrounding edge; The left and right sides of the outside surface of described front watchcase is arranged with the anti-skidding striped of some projections.
Preferred: the backboard of described rear watchcase comprises the central backboard adopting PC rigid plastic to make, and with described periphery sides and interior surrounding edge integrated TPU periphery backboard.
Preferably, described peripheral backboard and described central backboard adopt dual molding process to be combined as a whole.
Preferred: described gauge outfit, switch and circuit board are all fixedly mounted in described front watchcase; The central backboard of described rear watchcase is provided with battery cavities.
Preferred: described rear watchcase is fixed by screw and described front watchcase.
Preferred: the corner of described front watchcase and described rear watchcase is all rounded down.
The utility model has following beneficial effect: front watchcase adopts PC rigid plastic one-body molded, there is intensity high, dimensionally stable, on-deformable advantage, the waterproof construction of rear watchcase adopts TPU flexible glue to make, and with front watchcase interference fit, because TPU flexible glue has excellent elasticity, small distortion can be produced when interference fit, to make up some uneven part of front watchcase surrounding edge, thus form the water-proof wire sealed after front watchcase is combined with rear watchcase, thus water droplet and dust is prevented to enter in multimeter; The position that rear watchcase is made up of TPU flexible glue, plays buffer action when multimeter falls, thus makes that multimeter is anti-to be fallen; Anti-skidding striped can strengthen the friction force holding multimeter, prevents multimeter landing from hand, plays the effect of shatter-resistant.
Accompanying drawing explanation
Fig. 1 is the inner structure schematic diagram of front watchcase in the utility model;
Fig. 2 is the inner structure schematic diagram of rear watchcase in the utility model;
Fig. 3 is front watchcase Facad structure schematic diagram of the present utility model.
Embodiment
As shown in Figure 1 to Figure 3, a kind of pointer multimeter, comprises gauge outfit, switch, circuit board and watchcase, and described watchcase comprises front watchcase and rear watchcase; Described front watchcase adopts PC rigid plastic one-body molded; Described rear watchcase is provided with the waterproof construction with surrounding edge 1 interference fit of described front watchcase, and described waterproof construction comprises the periphery sides 2 and interior surrounding edge 3 made by TPU flexible glue, and the surrounding edge 1 of described front watchcase embeds in the gap between described periphery sides 2 and interior surrounding edge 3; The left and right sides of the outside surface of described front watchcase is arranged with the anti-skidding striped 6 of some projections.
In technique scheme, front watchcase adopts PC rigid plastic one-body molded, there is intensity high, dimensionally stable, on-deformable advantage, the waterproof construction of rear watchcase adopts TPU flexible glue to make, and with front watchcase interference fit, because TPU flexible glue has excellent elasticity, small distortion can be produced when interference fit, to make up some uneven part of front watchcase surrounding edge 1, thus form the water-proof wire sealed after front watchcase is combined with rear watchcase, thus prevent water droplet and dust to enter in multimeter; The position that rear watchcase is made up of TPU flexible glue, plays buffer action when multimeter falls, thus makes that multimeter is anti-to be fallen; Anti-skidding striped 6 can strengthen the friction force holding multimeter, prevents multimeter landing from hand, plays the effect of shatter-resistant.
Preferred: the backboard of described rear watchcase comprises the central backboard 4 adopting PC rigid plastic to make, and backboard peripheral with the integrated TPU of interior surrounding edge 3 with described periphery sides 2.Rear watchcase adopts soft or hard glue to combine, the peripheral backboard of TPU can strengthen buffer action, improve the crash resistance energy of multimeter, the central backboard 4 that PC rigid plastic is made, Stability Analysis of Structures, not yielding, thus when preventing hand-held multimeter, be pressed into the components and parts of multimeter inside, if whole rear watchcase all adopts TPU flexible glue to make, so, the components and parts of multimeter inside during hand-held multimeter, will be pressed into.
Preferably, described peripheral backboard and described central backboard 4 adopt dual molding process to be combined as a whole, and combine more firm, and improve the water resistance of multimeter between peripheral backboard and central backboard 4.
Preferred: described gauge outfit, switch and circuit board are all fixedly mounted in described front watchcase; The central backboard 4 of described rear watchcase is provided with battery cavities 5.Traditional pointer multimeter is fixedly installed in table by battery, and loading and unloading battery is very inconvenient, and battery cavities is arranged on central backboard by the utility model, and battery can put into battery cavities from the outside surface of central backboard 4, and loading and unloading battery is very convenient.
Preferred: described rear watchcase is fixed by screw and described front watchcase.Being fixed by screw, waterproof effect is better.
Preferred: the corner of described front watchcase and described rear watchcase is all rounded down.Fillet not only makes multimeter good looking appearance, prevents from scratching, and adopts round-corner transition, and sealing property is better.
