The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantages and features of the invention 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 more explicit defining.
From accompanying drawing 1 to accompanying drawing 11 structural representation as can be seen, the utility model provides the commutation children trolley, it comprises the go-cart vehicle frame, be installed in seat pocket 24 on the go-cart vehicle frame, be installed in front vehicle wheel 5 and the rear wheel 6 of go-cart vehicle frame below.
Go-cart vehicle frame in the present embodiment comprise strut 2 that front-wheel support 3 that the go-cart vehicle frame comprises that also top is connected and rear wheel support 4, the front vehicle wheel 5 that is installed in front-wheel support 3 bottoms, the rear wheel 6 that is installed in rear wheel support 4 bottoms, an end be connected the front-wheel support 3 top other ends and be connected with seat pocket 24, can before and after rotate and have a push rod 1 of former and later two control positioies at least.When push rod 1 during at first control position, push rod 1 relative strut 2 draws in, and when push rod 1 during at second control position, push rod 1 relative push rod 1 is opened.
The lower end of front-wheel support 4 is rotatably connected to preceding attaching parts 11, the first rotating shafts 12 with preceding slot 10 by first rotating shaft 12 and roughly vertically arranges.The lower end of front-wheel support 4 also is provided with the preceding latch 9 of pegging graft separatably with preceding slot 10 movably, and front vehicle wheel 5 is installed on the preceding attaching parts 11.The lower end of rear wheel support 4 is rotatably connected to rear connectors 16, the second rotating shafts 17 with back slot 15 by second rotating shaft 17 and roughly vertically arranges.The lower end of rear wheel support 4 also is provided with the back latch 14 of pegging graft separatably with back slot 15 movably, and rear wheel 6 is installed on the rear connectors 16.
The go-cart vehicle frame is provided with first trailer coupling and second trailer coupling.First trailer coupling is connected with back latch 14 and drives back latch 14 and moves, and second trailer coupling is connected with preceding latch 9 and drives preceding latch 9 and moves.
Front-wheel support 3 is provided with preceding latch 9 is applied the front spring 8 that power plugs itself and preceding slot 10.
Rear wheel support 4 is provided with back latch 14 is applied the rear spring 13 that power plugs itself and back slot 15.
First trailer coupling comprise setting be arranged on movably slide block 19, an end on the strut 2 be connected with slide block 19 first trailing cable 18 that the other end is connected with back latch 14, be arranged on the inclined-plane 22 that matches with slide block 19 on the push rod 1, slide block 19 can be arranged on the inside of strut 2 movably along strut 2 length directions, and offer one on the strut 2 along the waist hole that its length direction arranges, slide block 19 has the projection 21 that stretches out this waist hole and move in the waist hole.Strut 2 is provided with slide block 19 is applied the stage clip 20 that power makes it move up along strut 2 length directions.When push rod 1 during at first control position, push rod 1 relative strut 2 draws in, and inclined-plane 22 offsets with projection 21, and then promotes slide block 19 and move down along strut 2 length directions, and after back latch 14 inserts under the effect of rear spring 13 in the slot 15, thereby rear wheel 6 locks; When push rod 1 turns to second control position, push rod 1 relative strut 2 is opened, inclined-plane 22 is separated with projection 21, stage clip 20 promotes slide block 19 and moves up along strut 2 length directions, and drive back latches 14 by first trailing cable 18 and move and make it to be separated with back slot 15, thereby rear wheel 6 releases.
Second trailer coupling comprises that the runner 23 that is arranged on the push rod 1, an end connect second trailing cable 7 that the other end that is connected with runner 23 is connected with preceding latch 9, have distance between the connection of second trailing cable 7 and runner 23 and the turning cylinder of runner 23, namely the connection of second trailing cable 7 and runner 23 is not on the turning cylinder of runner 23.When push rod 1 turns at first control position from second control position, runner 23 rotates and drives second trailing cable 7, and then latch 9 moves and makes it to be separated with preceding slot 10 before driving, thus front vehicle wheel 5 releases; When push rod 1 turned to second control position, runner 23 rotated and discharge second trailing cable 7, slot 10 before preceding latch 9 inserts, thereby front vehicle wheel 5 releases under the effect of front spring 8.
From said structure is described as can be seen, evolution by push rod 1 drives first trailer coupling and the preceding latch 9 of second trailer coupling control and back latch 14 simultaneously, thereby realize the locking and unlocking control to directive texture on front vehicle wheel 5 and the rear wheel 6, the directed conversion of four-wheel is realized by push rod 1 commutation fully, need not other operations.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed within the protection domain of the present utility model.
