Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The first embodiment is as follows:

as shown in fig. 1-4, the present embodiment provides a locking type folding shopping cart, which comprises a basket 1, a handle 2, a front vertical rod 3, a rear vertical rod 4, a rear wheel 5 and a locking buckle 6.

The two ends of the handle 2 are respectively connected to a rear vertical rod 4, a rear wheel 5 is installed at the lower end of the rear vertical rod 4, and the rear wheel 5 is a triangular wheel.

The basket 1 comprises a plurality of ring bodies, the ring bodies 11 are hinged to the rear vertical rod 4, and the ring bodies 11 are also hinged to the front vertical rod 3 so as to be capable of linkage; basket 1 comprises a basket bottom 12; the ring body 11 positioned at the lowermost position is a bottom ring 110, and the basket bottom 12 includes the bottom ring 110.

A connecting rod assembly is also arranged below the basket bottom 12; the link assembly includes a front support bar 71 having one end hinged to a middle portion of the side bars 110a of the bottom ring 110, a rear support bar 72 hinged to a middle portion of the front support bar 71, the rear support bar 72 being mounted to the rear vertical bars 4 by a mounting shaft 73, the mounting shaft 73 being connected between the two rear vertical bars 4.

The end part of the front supporting rod 71 is also provided with a front wheel 8, and the front wheel 8 is a universal wheel.

The two front support rods 71 are connected through a connecting rod 74, the connecting rod 74 is a U-shaped connecting rod, and two ends of the U-shaped connecting rod are correspondingly installed on hinge shafts 75 of the front support rods 71 and the rear support rods 72 on the left and right sides.

In this embodiment, the basket bottom 12 includes a plurality of cross bars 121, the locking buckle 6 is mounted on the U-shaped link, and includes a shaft 61 and a hook 62, the shaft 61 is parallel to the cross bars 121, the hook 62 can hook one of the cross bars 121, and when the foldable shopping cart is in the unfolded state, if the front vertical bar 3 is moved upwards to cause the foldable shopping cart to have a tendency of being folded, the position of the U-shaped link where the shaft 61 is mounted and the cross bar 121 hooked by the hook 62 have a tendency of being separated, and under the action of the hook 62, the separation tendency can be prevented, so that the U-shaped link is locked with the basket bottom 12.

Similarly, in other embodiments, the locking buckle 6 may be mounted on the front support rod 71 or the rear support rod 72.

In addition, the number of the locking buckles 6 can be two, and the connecting rod assembly and the basket bottom 12 can be respectively locked by the two locking buckles 6 when the folding shopping cart is in a folded state and in an unfolded state during locking, that is, when one locking buckle 6 acts on the folded shopping cart in the unfolded state, the other locking buckle 6 acts on the folded shopping cart in the folded state. When the foldable shopping cart is in a folded state, if the front vertical rod 3 is moved downwards to cause the foldable shopping cart to have a tendency of unfolding, the position of the connecting rod assembly where the shaft part 61 is installed and the cross rod part 121 hooked by the hook part 62 (the cross rod part 121 can be the same cross rod part 121 as described above, or different cross rod parts 121) have a separation tendency, and the separation tendency can be prevented under the action of the hook part 62, so that the locking of the U-shaped connecting rod and the basket bottom 12 is realized.

Example two:

as shown in fig. 5 to 8, in the present embodiment, only one locking buckle 6 is disposed on the rear supporting rod 72, and at least two cross rods 121 are provided, and the two cross rods 121 are respectively used for being hooked by the locking buckle 6 in the folded state and the unfolded state.

In addition, the front vertical rod 3 and the bottom ring 110 are separately arranged, when the volume of the articles to be placed on the folding shopping cart is too large, the basket 1 cannot be installed, so that the front vertical rod 3 and the bottom ring 110 can be separated, and then the articles can be placed on the basket bottom 12, as shown in fig. 3 and 7.

In this embodiment, the lower end of the front vertical rod 3 is provided with an insertion buckle 31, and the insertion buckle 31 is detachably inserted and clamped on the bottom ring 110.
