In the bottom of the main body of the rolling cart 1 is a first mounting groove 11 provided recessed, the folding bike frame 3 in the first assembly groove 11 installed. The folding bike frame includes 3 a folding seat 31 , a folding arm 32 and a quick assembly mechanism 33 , with the folding seat on the lower surface 31 a second mounting groove 34 is provided recessed, and wherein the folding arms 32 provided in a number of 2 and each rotatable by a rotating shaft at the two ends of the second mounting groove 34 are arranged, and wherein the quick-mounting mechanism 33 at one end portion of the folding arm 32 is arranged; when unfolding the folding arm protrudes 32 out at both ends of the folding seat; when folding is the folding arm 32 in the second mounting groove 34 hidden; being the front wheels 4th on the quick-assembly mechanism 33 are arranged, and wherein the rear wheels 5 separately on the two sides of the stern of the base body 1 of the rolling cart are arranged; and wherein on the front part of the base body 1 of the rolling car a mounting block 12 is arranged protruding, and wherein on the mounting block 12 a first socket 13 in the vertical direction (height direction of the base body 1 of the rolling cart) is provided, and wherein on the mounting block 12 a second socket 14th from left to right (in the longitudinal direction of the body 1 of the rolling cart) is provided and extends to the interior of the base body 1 of the rolling cart extends; and being on the mounting block 12 a bolt hole 15th from front to back (in the width direction of the body 1 of the rolling cart) is provided, which through the first socket 13 goes and an overlaid section with the second socket 14th having, and wherein on the handle 6th a locking hole 61 is provided and wherein the handle 6th switchable in the first socket 13 and the second socket 14th is arranged, and being by a bolt 7th the bolt hole 15th and the locking hole 61 are connected to each other. When the folding bike frame 3 is unfolded is the handle 6th in the first socket 13 inserted, being through the bolt 7th the handle 6th attached, now it's a rolling cart for the kids. After folding the folding bike frame 3 becomes the handle 6th at the same time in the second socket 14th plugged in, now it's like a suitcase that can be dragged, and parents can drag the suitcase with one hand.

As in 1 to 3 shown is in the body 1 of the rolling cart, in one embodiment, has a storage cavity 16 provided, the seat cushion 2 with the front part of the main body 1 of the rolling car is articulated, and wherein the rear of the main body of the rolling cart is attached by a locking buckle. This will open and lock the seat cushion 2 realized. There are many structures for the locking buckle and belong to the state of the art; it is not explained in detail here. The storage box 16 can take the front wheels 4th at the same time some portable objects can be picked up.

As in 1 to 9 shown, includes the quick-mount mechanism 33 in one embodiment a connecting shaft 331 , a plug-in block 332 , an insulation sleeve 333 and a locking block 334 , the connecting shaft 331 firmly on the folding arm 32 is arranged, the two can be connected to one another by welding, in addition, they can be designed as a one-piece structure. At one end of the connecting shaft 331 a mounting hole is recessed, which is designed as a cuboid structure, wherein a continuous guide hole is provided at two ends of the mounting hole, and wherein the locking block 334 is slidably disposed in the guide hole at the two ends, and wherein the insulating sleeve 333 is arranged in the mounting hole and fixedly connected to the mounting hole, and wherein the plug-in block 332 a block body that fits into the inner hole of the insulation sleeve 335 and a magnet disposed at the end portion of the block body 336 comprises, and wherein the plug-in block 332 in the insulation sleeve 333 is inserted, and which is the locking block 334 is a magnet, and where the locking block 334 protrudes from the guide hole when the magnet 336 and the locking block 334 have a same magnetic pole; and wherein the locking block 334 is hidden in the guide hole with opposite magnetic poles. This includes the front wheel 4th a connecting section 41 and a rolling section 42 , where the rolling section 42 rolling through a bearing with the connecting section 41 is connected, and wherein the connecting portion 41 with the quick assembly mechanism 33 connected is. At the connecting section 41 a through-hole is axially provided, a communication hole in the through-hole 43 provided when the front wheel 4th with the quick assembly mechanism 33 connected is the locking block 334 in the connecting hole 43 plugged in. When installing the front wheel 4th becomes the plug-in block 332 plugged in so that the plug-in block 332 and the locking block 334 have opposite magnetic poles on the two sides, the locking block 334 is hidden in the guide hole, then the front wheel is attached to the connecting shaft 331 on top, the locking block also corresponds 334 with the connecting hole 43 in the front wheel 4th , the plug-in block 332 is pulled out and inserted after turning 180 ° so that the plug-in block 332 and the locking block 334 have the same magnetic pole on both sides, the locking block 334 is pushed out of the guide hole and into the connecting hole 43 of the front wheel 4th plugged in for quick assembly of the front wheel 4th complete; When dismantling, only the magnetic pole of the plug-in block should be used 332 changed to the locking block 334 tighten so that the locking block 334 is hidden in the guide hole, this allows the front wheel 4th be dismantled. After the front wheel 4th into the connecting shaft 331 was nested, the connection hole may 43 cannot be observed, so assembly is inconvenient, but under the effect of the principle that magnets with the same pole repel each other, the magnetic pole of the plug-in block can 332 can be changed by the front wheel 4th is nested so that the locking block 334 is pushed out, now is the locking block 334 on the inner wall of the through hole of the front wheel 4th attached, only the position of the front wheel should be 4th adjusted until a “click” is heard, meaning the locking block 334 in the connecting hole 43 of the front wheel 4th is plugged in.

As in 1 to 9 shown, forms the magnet 336 in the above embodiment a clearance fit with the insulating sleeve 333 , the block body 335 with the insulation sleeve 333 fits tight. The block body is preferred 335 made of plastic, since the plastic can be easily compressed compared to metal, the plug-in block 332 be plugged in more easily.

As in 1 to 9 shown includes the locking block 334 in one embodiment, a locking block body 337 and a locking portion 338 , wherein the locking portion 338 on the lock block body 337 and formed as a step-like structure, and wherein the guide hole is a step-like hole mating with the lock block, and wherein it is the lock block body 337 is a magnet. Under the action of the fit between the guide hole formed in a stepped structure and the insulating sleeve 333 it will ensure that the locking block is 334 located in the guide hole and not from the connecting shaft 331 replaces. The guide hole is preferably designed in the structure of a cuboid hole.

As in 1 to 9 is shown on a side wall of the connecting shaft 331 a positioning surface 339 arranged, the through hole of the front wheel 4th with the connecting shaft 331 fits. Namely, in the through hole there is one with the positioning surface 339 matching surface, when the two surfaces are in contact, it will ensure that the locking block 334 with the connecting hole 43 corresponds.

As in 1 to 9 shown is the connecting shaft 331 in a preferred embodiment made of plastic. The isolation sleeve 33 can also be made of plastic, this can reduce the influence on the magnet; of course, other materials that are not attracted by the magnet can also be used.

As in 1 to 9 shown is on the inner wall of the second mounting groove 34 in one embodiment a mounting hole 37 provided, the mounting hole 37 the position of the locking block on the folding arm located at a folding point 32 corresponds. When the folding arm 32 is on the folding point, the locking block 334 unloaded and in the mounting hole 37 inserted, this allows the lock between the folding arm 32 and the folding seat 31 to be completed.
