Abstract
The utility model discloses a brushless portable vibrator belongs to portable vibrator technical field, its involving vibrations stick, casing and arrange the casing in the motor, the motor be single -phase asynchronous motor, the output shaft of motor passes through the connector and is connected with the vibrting spear and drives the vibrting spear and move. The utility model discloses simple structure, the radiating effect is good, and output is big, long service life.
Description
Technical field
The utility model belongs to portable vibration device technical field, is specifically related to a kind of brushless portable vibration device.
Background technology
Portable vibration device is mainly used in power electric inconvenience, mixed earth vibrates less demanding rural area, along with the development of society, building houses of countryside requires more and more higher, and the consumption of steel concrete progressively increases, existing vibrator has the following disadvantages: 1, portable vibrator adopts series excited machine acceleration device, then connect vibrating head, power output is little, and large vibrating head cannot start, carbon brush in series excited machine easily weares and teares, application life is short, and carbon brush needs professional to change, and changes inconvenient; 2, existing portable vibration device carries out speed governing by gear drive, drive vibrating head motion by outer-hexagonal axle connector, outer-hexagonal axle connector is faced directly short easy to wear, skids once wearing and tearing easily cause vibrating head to be connected with output shaft, fault rate is high, and consumed energy; 3, existing portable vibration device casing adopts nylon structure, and in casing internal heat radiation, heat dispersion is poor, and when in motor, stator temperature progressively increases, casing can deform, stable poor, and uses inconvenient.
Utility model content
The utility model object is to provide the brushless portable vibration device that a kind of structure is simple, power output is large.
For achieving the above object, the utility model is by the following technical solutions: a kind of brushless portable vibration device, involving vibrations rod, casing and the motor that is placed in casing, described motor is monopole asynchronous motor, and the output shaft of motor to be connected with vibrating head by connector and to drive vibrating head to move.
Described casing is also provided with ventilation protective cover outward, and be provided with air intake and air outlet between described ventilation protective cover and casing, described air inlet is provided with heat emission fan.
Described ventilation protective cover adopts nylon plastic(s) to make.
Described heat emission fan is connected with the output shaft of motor.
Described connector is outer corner axle construction.
Compared with prior art, the beneficial effects of the utility model are:
1, the motor in the utility model is monopole asynchronous motor, non-carbonate structure, and power output is large, does not need gear drive speed governing, and output shaft directly drives vibrating head motion by connector, effectively reduces fault rate, long service life;
2, the casing in the utility model is also provided with ventilation protective cover outward, ventilation protective cover adopts nylon plastic(s) to make, softening point is high, heat-resisting, prevent the too high personnel of causing of shell temperature from scalding, be provided with air intake and air outlet between ventilation protective cover and casing, the output shaft of motor is also connected with heat emission fan, to casing outer surface heat radiation, radiating efficiency is high;
3, the connector in the utility model is outer corner axle construction, not easy to wear, is not easy to loosen.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
One is as shown in Figure 1 brushless portable vibration device, involving vibrations rod, casing 1 and the motor be placed in casing 1, casing 1 adopts aluminum alloy materials to make, perfect heat-dissipating; Casing 1 is outer is also provided with ventilation protective cover 2, and ventilation protective cover 2 adopts nylon plastic(s) to make, and it is high that nylon plastic(s) has softening point, heat-resisting, prevents the too high personnel of causing of shell temperature from scalding, plays a protective role; Ventilation protective cover 2 is provided with handle 6 and power switch 7, facilitates portable and operation, is provided with air intake 3 and air outlet 4 between casing 1 and ventilation protective cover 2, air intake 3 place is provided with heat emission fan 5, heat emission fan 5 is connected with the output shaft of motor, and heat emission fan 5 is for casing 1 surface radiating, and radiating efficiency is high; Motor in casing 1 is monopole asynchronous motor, non-carbonate structure, and power output is large, does not need gear drive speed governing, and the output shaft of motor to be also connected with vibrating head by connector and to drive vibrating head to move; Connector adopts outer corner axle construction, is not easy to loosen, effectively reduces fault rate, long service life; During use, switch on power, hold handle 6, turn on the power switch 7, now motor runs, and motor drives vibrating head vibration by motor output shaft; Now heat emission fan 5 is also rotated, and air is discharged from air outlet 4 enter the heat taking away casing 1 surface from air intake 3 after, and casing 1 surface temperature is reduced.The utility model structure is simple, perfect heat-dissipating, failure rate is low, long service life.
