After the locking sleeve 7 is unlocked, the movable rod 41 and the connecting piece 42 slide relative to the upper connecting rod 21, the lower end of the connecting piece 42 drives the first linkage rod 61 to slide, the first linkage rod 61 pulls the second linkage rod 62 to move, one end of the second linkage rod 62 pulls the front wheel assembly 5 to rotate and approach the lower connecting rod 22, meanwhile, the first linkage rod 61 also pushes the third linkage rod 63 to move transversely, the opening 632 of the third linkage rod 63 is aligned with the cross rod 13 in the moving process of the third linkage rod 63, at the moment, the third linkage rod 63 is not subjected to other pulling forces, therefore, when the opening 632 of the third linkage rod 63 is aligned with the cross rod 13, the third linkage rod 63 can automatically separate from the cross rod 13 through self weight, at the moment, the first linkage rod 61 and the second linkage rod 62 can move along with the connecting piece 42, then the lower connecting rod 22 is pulled upwards, the front wheel assembly 5 is pulled to move upwards when the lower connecting rod 22 moves upwards, and the connecting piece 42 moves downwards under the driving of the upper connecting rod 21, and the two are matched to enable the first linkage rod 61 to move downwards and pull the second linkage rod 62 to rotate, so that the front wheel assembly 5 is close to the lower connecting rod 22.
As shown in fig. 1, a handle assembly 8 is rotatably connected to the top of the supporting frame 1 about a fifth axis E. The handle assembly 8 facilitates pushing by a user. The supporting frame 1 and the hand push handle assembly 8 are locked through the quick locking structure, when the foldable shopping cart is folded, the hand push handle assembly 8 rotates around a fifth axis E relative to the supporting frame 1, the height of the foldable shopping cart is changed, the size of the foldable shopping cart after being folded is the smallest, and the occupied space is smaller compared with the existing foldable shopping cart.
As shown in fig. 3, the handle assembly 8 includes a support rod 81 rotatably connected to the support frame 1, a laterally extending handle 82 is rotatably connected to the support rod 81, a locking device 83 is disposed between the handle 82 and the support rod 81 for locking the handle 82 and the support rod 81, and an L-shaped support frame 821 is further disposed on the handle 82 for abutting against the support rod 81 after 90 ° turnover. When the L-shaped supporting frame 821 is abutted against the supporting bar 81 after the push bar 82 is turned over by 90 degrees, the push handle assembly 8 can be used as a walking aid for the support of the old or the handicapped. The locking device 83 may be a quick-fit screw and hole arrangement or a spline arrangement.
As shown in fig. 2, the pulley assembly 11 includes a wheel support frame 111 rotatably connected to the support frame 1, and a plurality of wheels 112 are disposed on the wheel support frame 111. When the foldable shopping cart climbs stairs, the wheels 112 are rubbed by the stairs to drive the wheel support frame 111 to rotate, and when the wheel support frame 111 rotates, the other wheel 112 contacts with the previous step or the next step, so that the foldable shopping cart is more labor-saving when climbing stairs.
As shown in fig. 2, a window 900 is formed between the upper connecting rod 21 and the lower connecting rod 22 and the movable frame 4 when the foldable shopping cart is unfolded. When the foldable shopping cart is used, a shopping bag is generally sleeved on the surrounding frame 2, objects in the shopping bag can be extruded outwards from the window 900 when the objects are more, and compared with the existing shopping cart, the foldable shopping cart can prevent the objects in the shopping bag from being crushed or damaged due to the extrusion of the objects in the shopping bag and the rod pieces of the surrounding frame.
As shown in fig. 4, the supporting frame 1 is rotatably connected with a supporting net rack 23 which can be drawn close to the lower connecting rod 22 when the foldable shopping cart is unfolded, the supporting net rack 23 is formed by connecting a plurality of rod members, a yielding groove 24 which can yield for the connecting piece 42 is arranged between the supporting net rack 23 and the lower connecting rod 22, and the supporting net rack 23 is further provided with a positioning groove 231 which can respectively position each front wheel assembly 5. The abdicating groove 24 can abdicating the connecting sheet 42, so that the connecting sheet 42 can slide and can not lean against the supporting net rack 23, the supporting net rack 23 is formed by welding metal rod pieces and is used for supporting articles, although the friction resistance between the front wheel assembly 5 and the lower connecting rod 22 can prevent the front wheel assembly 5 from transversely sliding, the positioning groove 231 can lock the upper part of the front wheel assembly 5, and the front wheel assembly 5 is prevented from shaking.
As shown in fig. 8, the supporting net rack 23 is provided with a first inclined sliding surface 232, and the connecting sheet 42 is provided with a pressing block 421 which can press the first inclined sliding surface 232 to make the supporting net rack 23 and the lower connecting rod 22 tightly contact when the foldable shopping cart is unfolded. When the foldable shopping cart is unfolded, the jacking block 421 jacks the first inclined sliding surface 232 of the support net rack 23 to make the support net rack 23 tightly attached to the lower connecting rod 22, so as to avoid a gap between the support net rack 23 and the lower connecting rod 22 and further avoid the support net rack 23 from rotating randomly.
