The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As depicted in figs. 1 and 2, a kind of mobile pharos that the embodiment of the present invention provides, can be used for the fields such as outdoor emergency illumination.Above-mentioned mobile pharos comprises car body 1, illuminace component 2 and liftable elevating lever 3, elevating lever 3 is rotationally connected with on car body 1, illuminace component 2 is connected in elevating lever 3, and illuminace component 2 can slide up and down under elevating lever 3 effects, and can change direction of illumination with synchronous rotation of elevating lever 3.
Particularly, as shown in Figures 2 and 3, on car body 1, be rotatably connected to connecting rod 4, between connecting rod 4 and elevating lever 3, apart arrange, between connecting rod 4 and described elevating lever 3, be provided with power-assisted transmission apparatus, power-assisted transmission apparatus comprises gear wheel 51 and pinion 52, and the diameter of gear wheel 51 is greater than the diameter of pinion 52; Gear wheel 51 is fixed on elevating lever 3, and pinion 52 is fixed on connecting rod 4; Gear wheel 51 can be located on elevating lever 3 roots by fixed cover, and pinion 52 can fixedly be fixedly arranged on connecting rod 4 roots.Pinion 52 directly meshes with gear wheel 51, or pinion 52 is engaged in gear wheel 51 by gear train, is connected with the rotating disk 63 for driving connecting rod 4 and can rotating relative to car body 1 on connecting rod 4.Operating personnel can be by rotating rotating disk 63 to drive connecting rod 4 rotations, and connecting rod 4 can drive the rotations such as illuminace component 2 on elevating lever 3 and elevating lever 3 by power-assisted transmission apparatus.Mobile pharos provided by the present invention, it is by adopting pinion 52 that diameter is less as driving gear, adopt gear wheel 51 that diameter is larger as driven gear, gearratio between pinion 52 and gear wheel 51 is greater than the ratio of input speed and output speed in the so-called gearratio ，Zhi of 1(mechanism).Gearratio is larger, and output speed is slower, torsion is larger.When driving gear is than driven gear hour, driven gear turns slowlyer than driving gear, and gear pair works to slow down, increase moment of torsion.The pinion 52 that for example number of teeth is 12 drives the gear wheel 51 that the number of teeth is 24.If the driving gear that the number of teeth is 12 rotates with the moment of torsion of 10 (N.m), the driven gear that the number of teeth is 24 often turns around, and the driving gear that the number of teeth is 12 will take two turns.The driving torque of driven gear is just many one times like this.Now the moment of torsion of driven gear is 20(N.m).Like this, pinion 52 just can drive gear wheel 51 rotations by less power, thereby has reached the effect of power-assisted, thereby has improved operating personnel's operating efficiency, has reduced operating personnel's labour intensity, and product is used very convenient.During concrete application, diameter, the number of teeth of gear wheel 51, pinion 52 can be determined according to actual conditions, as long as the diameter of gear wheel 51 is greater than the diameter of pinion 52.
