The specific embodiment
Below by specific embodiment, the present invention is further described in detail.
A kind of handle arm structure of transport trolley, comprise control arm 1 and Brake Block 2, control arm 1 below is provided with cam 4, cam 4 is rotating to be connected on Brake Block 2, Brake Block 2 inside are provided with a micro-switch 3, and described cam 4 and described micro-switch 3 cooperatively interact, when control arm 1 is depressed into certain angle, thereby cam 4 rotates to trigger and is arranged on the micro-switch 3 on Brake Block 2, plays the effect to transport trolley brake.
The outer rim of cam 4 one sides is respectively equipped with the first groove 41, projection the 43 and second groove 42, the first grooves 41 and the second groove 42 to the center of circle depression of cam, and the middle not part of depression forms projection 43.Micro-switch 3 is controlled braking and the release of vehicle, it comprises roller 31, pressing plate 32, button 33 and Switch main body 34, roller 31 is located on pressing plate 32 and is corresponding with the first groove 41, projection 43 and second groove 42 positions of cam, pressing plate 32 is hinged on Switch main body 34, and button 33 is located at Switch main body 34 surfaces.
Be illustrated in figure 2 the structural representation of the utility model initial condition.Under control arm 1 initial condition, the roller 31 of micro-switch 3 is positioned at the first groove 41 of cam 4, and pressing plate 32 is in extended configuration, and micro-switch does not trigger, and transport trolley is in normal motoring condition.Be illustrated in figure 3 the structural representation of braking state of the present utility model.Control arm presses down certain angle, and now roller 31 is positioned at protruding 43 places, and projection 43 presses down the pressing plate 32 of micro-switch, thereby triggers micro-switch, provides signal to vehicle, car brakeing brake.Be illustrated in figure 4 the structural representation that the utility model control arm presses down.Control arm presses down, and roller 31 is positioned at the second groove 42, and pressing plate 32 is in extended configuration, and micro-switch does not trigger, and micro-switch restPoses.
In addition, the invention is not restricted to above-mentioned embodiment, as long as within not exceeding scope of the present invention, can take variety of way to implement the present invention.
