The specific embodiment
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 more explicit defining.
From accompanying drawing 1 to accompanying drawing 2 structural representation as can be seen, present embodiment is that example illustrates this fold mechanism with a kind of children trolley.The go-cart vehicle frame of children trolley comprises that upper push-rod 1, top insert in the upper push-rod 1 from the bottom of upper push-rod 1 and the lower push-rod 2 that stretches of upper push-rod 1, the front-wheel support 17 that rotates and be connected with the bottom of lower push-rod 2 relatively in the present embodiment, be socketed in the sliding sleeve 5 on the upper push-rod 1 slidably, top is rotatably connected on the rear wheel support 3 on the sliding sleeve 5, front vehicle wheel is installed in the bottom of front-wheel support 17, and rear wheel is installed in the bottom of rear wheel support 3.The top of rear wheel support 3 is fixedly connected with a rear wheel support top connection 4, and this rear wheel support top connection 4 connects pin 16 by being automatically connected on the sliding sleeve 5 by a rear wheel support.
The top of lower push-rod 2 is provided with the moving locking device of relative position between restriction upper push-rod 1 and the lower push-rod 2, upper push-rod 1 is provided with removable and passes through the mobile tripper that the first hard trailing cable 10 is controlled the moving locking device releases, one end of the first hard trailing cable 10 fixes with mobile tripper and is connected with one first stop part 18 after the other end passes moving locking device movably, when lower push-rod 2 relative upper push-rods 1 stretch out, first stop part 18 offsets with the bottom of moving locking device, when lower push-rod 2 relative upper push-rods 1 shrank, first stop part 18 was away from moving locking device.
Moving locking device comprise the hole clipping that is arranged on the upper push-rod 1, can along lower push-rod 2 move radially and with upper push-rod 1 on hole clipping clamping separatably bayonet lock 14, can move axially and promote first sliding block 15 that bayonet lock 14 breaks away from hole clippings along lower push-rod 2.First sliding block 15 is provided with an inclined-plane 20, and this inclined-plane 20 matches with bayonet lock 14, and when moving on first sliding block 15, promote bayonet locks 14 by inclined-plane 20 and move and withdraw from hole clipping, thus the moving locking device release.
An end and first top shoe 8 that mobile tripper comprises first top shoe 8 that moves along its axis that is arranged on upper push-rod 1 inside, be arranged on upper push-rod 1 mobile release handle 7, the first hard trailing cables 10 outside and that fix with first top shoe 8 fix.Move when upwards spurring on mobile release handle 7, the first top shoes 8, drive on first sliding block 15 by the first hard trailing cable 10 and move, thus the release moving locking device, and upper push-rod 1 can slide relatively with lower push-rod 2.Because employing is unidirectional spacing the connection between the first hard trailing cable 10 and first sliding block 15, when upper push-rod 1 shrinks with lower push-rod 2 relative slips, be that upper push-rod 1 is during along lower push-rod 2 to lower slider, the first hard trailing cable 10 can move down thereupon, do not move but can not drive first sliding block 15, and the first hard trailing cable 10 can movement and deformation.
Be provided with the rotation lock device 13 that limits the two relative position between front-wheel support 17 and the lower push-rod 2, be provided with second sliding block 12 of movably also controlling rotation lock device 13 releases by soft trailing cable in the lower push-rod 2, upper push-rod 1 is provided with removable and drives the rotation tripper that second sliding block 12 moves by the second hard trailing cable 11, one end of the second hard trailing cable 11 fixes with the rotation tripper and is connected with one second stop part 19 after the other end passes rotation lock device movably, when lower push-rod 2 relative upper push-rods 1 stretch out, second stop part 19 offsets with the bottom of rotation lock device, when lower push-rod 2 relative upper push-rods 1 shrank, second stop part was away from rotation lock device.
Rotate tripper comprise be arranged on inner and second top shoe 9 that can move along its axis of upper push-rod 1, to be arranged on upper push-rod 1 outside and have a rotation unlock button 6 that second top shoe 9 is connected.Offer skewed slot 21 on second top shoe 9, rotate unlock button 6 and be provided with the projection that matches and be connected with this skewed slot 21, this projection can move in skewed slot 21, when pressing rotation unlock button 6, under the mating reaction of projection and skewed slot 21, second top shoe 9 is pushed and moves, thereby drives rotation lock device 13 releases by the second hard trailing cable 11 and second sliding block 12.And owing to also adopt unidirectional spacing the connection between the second hard trailing cable 11 and second sliding block 12, second trailing cable 11 can spur second sliding block 12 and move up, but when upper push-rod 1 during along lower push-rod 2 to lower slider, the second hard trailing cable 11 can move down thereupon, but can not drive second sliding block 12 and move, and the second hard trailing cable 11 can movement and deformation.
Second sliding block 12 is arranged on the below of first sliding block 15, and the second hard trailing cable 11 passes first sliding block 15 movably.
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.
