Detailed description of the invention
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
with reference to accompanying drawing 1 to accompanying drawing 9, in the present embodiment, it comprises the trolley rack 2 that the go-cart body 1 of wheel 3 is installed, is removably connected and is also provided with wheel 3 with go-cart body 1, on go-cart body 1, be provided with connecting pin 4, sliding pin 5 slidably, on trolley rack 2, offer the U-lag 6 matching with connecting pin 4 and plug separatably, the sliding pin hole 7 of matching and being connected separatably with sliding pin 5.
sliding pin 5 moves by the cam mechanism driving being arranged on go-cart body 1.Cam mechanism comprises and is fixedly connected on go-cart body 1 and has the first cam 10 of the first helical surface 11, be fixedly connected with sliding pin 5 with the first cam 10 the second cam 12, the second cams 12 that are connected and have the second helical surface 13 of matching with the first helical surface 11 that rotate.In the present embodiment, the second cam 12 is by rotating and be connected between sliding pin 5 and the first cam 10, and its concrete structure is: the first cam 10 center has a through hole 15, and sliding pin 5 passes this through hole 15, and rotates and be connected with this through hole 15.
on trolley rack 2, be fixedly installed a positioning block 18, sliding pin hole 7 is opened on this locating piece 18.On go-cart body 1, be also fixedly installed a block 16, on block 16, offer a hole 17.Cam mechanism has two kinds of mode of operations, when cam mechanism is during at the first mode of operation, the first helical surface 11 and the second helical surface 13 fit, sliding pin 5 plugs with the hole 17 on block 16, if now sliding pin 5 is connected with sliding pin hole 7, locating piece 18 is between block 16 and the first cam 10, and block 16 can play the effect that sliding pin 5 and sliding pin hole 7 are not departed from; When cam mechanism is during at the second mode of operation, the second cam 12 rotates, the first helical surface 11 and the second helical surface 13 relative slidings make the second cam 12 drive sliding pin 5 to move, and sliding pin 5 is separated with the hole 17 on block 16, now sliding pin hole 7 can be separated or be connected with sliding pin 5.
