Embodiment
The utility model proposes a kind of device of realizing the sinusoidal vertical vibration test of baby carrier, to satisfy in standard EN 13209-1:2004 of European Union and the test request of EN 13209-2:2005 for baby carrier, need be under loading condition to baby carrier, implementing frequency is 2 hertz, and amplitude is the test request of the vertical sinusoidal vibration of 120mm.
As shown in Figure 1, this device comprises: motor 1, this motor 1 external power supply and gauge tap; With the drive mechanism that motor 1 rotating shaft is connected, this drive mechanism comprises: driving belt is or/and transmission gear, or even each transformation into itself's combination of driving belt and transmission gear, and reducer casing 2; This reducer casing 2 by moving belt or/and transmission gear connects an eccentric wheel 3 that is used for power conversion is become circular motion; This eccentric wheel connects the sinusoidal motion that the movement locus that is used for eccentric wheel 3 converts the sinusoidal motion of vertical direction to and produces structure 4, and this sinusoidal motion produces structure 4 and connects and drive the 5 pairs of Baby carriers of metal dummy that hang Baby carriers to carry out frequency be that 2 hertz, amplitude are the test of the vertical sinusoidal vibration of 120mm; Be arranged on sinusoidal motion and produce the infrared induction counter 6 that structure one side is used to write down vibration number.
In conjunction with Fig. 2 and shown in Figure 3, sinusoidal motion produces structure 4 and comprises: base 41; Be vertically set on two guide rails 42 on the base 41; Be arranged on two slide blocks 43 between the guide rail 42, this slide block 43 has a horizontal groove 432; Be embedded in the horizontal groove 432 of slide block 43 and be arranged on the cam 31 that is provided with on the eccentric wheel 3.Wherein, cam 31 is 60mm apart from the radius in eccentric wheel 3 centers of circle, can do the uniform circular motion that radius is 60mm around eccentric wheel 3 centers of circle, and circular motion amplitude up and down is 120mm just; Simultaneously, the length of the horizontal groove 432 that this cam 32 is embedded into just also is that 120mm. passes through the fixing of two side rails 42, and slide block 43 can only be limited in vertical direction and carry out sinusoidal motion up and down.
Therefore, after starting power supply, motor 1 rotates, and by reducer casing 2 and drive mechanism power is passed to eccentric wheel 3 and makes it carry out uniform circular motion, produce the motion feature that structure 4 is utilized eccentric wheel 3 by sinusoidal motion then, change into the sinusoidal vibration of vertical direction by guide rail 42.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
