A limit hole 111 is provided at the position, and the rotation locking assembly 7 passes through the rotation hole 152 and the limit hole 111 to lock the protective sleeve 15 and the storage slot 11 at 90 degrees. The left and right inner walls of the storage slot 11 are provided with slide grooves 16 along the length direction, and a slide bar 17 passing through the protective sleeve 15 is slidably connected between the two slide grooves 16. A storage bag 3 with a zipper 19 is provided on the side of the storage bag 2 away from the stretching rod 4, and the storage bag 3 can be turned inside and wrap the support frame 1. After the stretching rod 4 is laid flat and shortened, the stretching rod 4 and the protective sleeve 15 can be stored in the storage slot 11. In the process of pushing the storage slot 11, the slide bar 17 on the protective sleeve 15 slides in the slide groove 16. The slide bar 17 and the slide groove 16 cooperate to play a fixing and guiding role, which increases the connection firmness between the stretching rod 4 and the support frame 1 and the stability of the stretching rod 4 storage process.

[0033] The rotation locking assembly 7 includes a connecting tube 74 passing through the two rotating holes 152, a second spring 73 arranged inside the connecting tube 74, two ends of the second spring 73 abutting against the second pin 72, and a second button 71 passing through the limiting hole 111 and abutting against the second pin 72. The connecting tube 74 is provided with a second spring 73 and a second pin 72. When the second pin 72 is clamped between the protective sleeve 15 and the receiving groove 11 under the influence of the elastic force of the second spring 73, the stretching rod 4 is locked at 90 degrees relative to the supporting frame 1. When the second button 71 is pressed to completely press the second pin 72 into the connecting tube 74, the constraint between the protective sleeve 15 and the receiving groove 11 is released, and the stretching rod 4 can be rotated relative to the supporting frame 1, and then the stretching rod 4 is laid flat and placed into the receiving groove 11 to complete the storage of the stretching rod 4. The whole process is simple to operate and easy to implement.

[0034] The lower surface of the front end of the carrier 1 is symmetrically fixedly connected with two fixing frames 12, one side of the fixing frame 12 is provided with a wheel bracket 5, a rotating shaft 13 passes through the fixing frame 12 and the wheel bracket 5 and makes the fixing frame 12 and the wheel bracket 5 rotatably connected, the wheel bracket 5 is fixed to the fixing frame 12 by rivets, a sleeve 14 is provided in the rotating shaft 13, one end of the sleeve 14 is closed, and the other end of the sleeve 14 passes through the rotating shaft 13, and a hinge locking component 9 is provided in the sleeve 14 to lock the wheel bracket 5 and the carrier 1 at 90 degrees. The wheel bracket 5 is rotatably connected with the carrier 1, which facilitates the fitting of the moving wheel 8 with the carrier 1, and plays a storage effect, and the hinge locking component 9 is provided to keep the moving wheel 8 upright, which is convenient for keeping the shopping cart stable.

[0035] The hinge locking assembly 9 includes a first spring 93 placed in the sleeve 14, one end of the first spring 93 abuts against the inner wall of the rotating shaft 13, the other end of the first spring 93 abuts against the first pin 92, and the first button 91 passes through the fixing frame 12 and abuts against the first pin 92. The first spring and the first pin are installed in the sleeve. When the first pin is clamped between the fixing frame 12 and the rotating shaft 13 under the influence of the elastic force of the first spring, the wheel bracket 5 and the moving wheel 8 are locked at 90 degrees relative to the supporting frame 1. When the first button 91 is pressed to completely press the first pin 92 into the sleeve, the constraint between the rotating shaft 13 and the fixing frame 12 is released, and the wheel bracket 5 can rotate relative to the supporting frame 1, thereby rotating the moving wheel 8 close to the lower end of the supporting frame 1, and completing the storage of the moving wheel 8.

[0036] The rear end side wall of the storage slot 11 is rotatably connected with a support leg 6, and a placement block 18 is fixedly connected to the lower surface of the carrier frame 1 near the support leg 6, and a ball is installed on the placement block 18. When the support leg 6 is in an upright state, the ball extends from the placement block 18, which has a certain limiting effect on the rotation of the support leg 6, which is convenient for keeping the shopping cart stable. When the support leg 6 needs to be stored, the ball can be squeezed into the placement block 18 by slightly rotating the support leg 6. The structure is simple and easy to operate.

[0037] The upper end of the inner side wall of the storage bag 3 is symmetrically fixedly connected with a hand strap 10. The storage bag 3 is turned inside out and wraps the entire folded shopping cart. The hand strap 10 is arranged on the upper end of the storage bag 3, which is convenient for users to carry after storing the shopping cart.

[0038] The mechanical principle of the folding and storage of the moving wheel 8 is as follows: when the moving wheel 8 is opened and the shopping cart is in a moving state, the first pin 92 in the sleeve 14 in the hinge locking assembly 9 automatically pops out, and the first button 91 is lifted up to lock the moving wheel 8. That is, the moving wheel 8 always remains in an upright state. At this time, the moving wheel 8 is just in a vertical state with the carrier frame 1, and the moving wheel 8 rolls along the ground to drive the shopping cart to move. When the moving wheel 8 needs to be folded, the first button 91 is pressed, and the first spring 93 is compressed to retract the first pin 92 into the sleeve 14. At this time, the moving wheel 8 is close to the bottom surface of the carrier frame 1 and is in a folded and stored state. The moving wheel 8 and the wheel bracket 5 are folded and fit on the bottom surface of the carrier frame 1. This design makes it easier to open and fold the moving wheel 8.

[0039] The mechanical principle of the folding and storage of the stretching rod 4 is as follows: when the stretching rod 4 is to be pulled up and erected, the stretching rod 4 is first stretched and lifted, the compression spring embedded in the multi-section pull rod pops up, the positioning pin pops out, and the length of the stretching rod 4 is locked. When the stretching rod 4 and the protective sleeve 15 are upright and perpendicular to the carrier frame 1, the second pin 72 pops out from the connecting tube 74 and is clamped between the protective sleeve 15 and the storage groove 11 to complete the locking of the protective sleeve 15 and the storage groove 11. When the stretching rod 4 and the protective sleeve 15 are retracted, the specific implementation is to press the second button 71, the second spring 73 is squeezed, and the second pin 72 is pushed back to the connecting tube 74 to separate the protective sleeve 15 from the storage groove 11. At this time, the stretching rod 4 is laid flat and pushed parallel to the storage groove 11 in the carrier frame 1 to complete the storage.

[0040] The mechanical principle of the folding and storage of the support leg 6 is as follows: when the support leg 6 is in an upright state, the ball protrudes from the placement block 18, which limits the rotation of the support leg 6 to a certain extent, thereby facilitating the stability of the shopping cart. When the support leg 6 needs to be stored, the ball can be squeezed into the placement block 18 by simply turning the support leg 6 with a little force. At this time, the support leg 6 can be rotated and fit into the lower surface of the support frame 1.

[0041] After the stretching rod 4, the moving wheels 8 and the supporting legs 6 are folded and stored, the user needs to lie the storage bag 2 down on the supporting frame 1, and fold the storage bag 2 toward the lower end of the supporting frame 1, unzip the zipper 19 on the storage bag 3, and fold the storage bag 3 reversely to wrap the entire supporting frame 1. At this time, the shopping cart is stored into a handbag-like structure, which is convenient for the user to carry or store, solving the problem that the existing shopping cart is very inconvenient to carry and occupies a large amount of storage space.
