Utility Model Content

[0003] The technical problem solved by this utility model is to provide an integrated shopping cart frame to improve the smoothness and flatness of the frame surface.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an integrated shopping cart frame, including a bottom load-bearing structure and a side push-pull structure. The bottom load-bearing structure is equipped with rollers. The bottom of the side push-pull structure is connected to the bottom load-bearing structure. The top of the side push-pull structure is equipped with a handle. The bottom load-bearing structure adopts an integrated structure. The side push-pull structure and the handle adopt an integrated structure. The bottom of the side push-pull structure is connected to the bottom load-bearing structure through a triangular connector. The connector passes upward from the bottom of the bottom load-bearing structure through the triangular connector and connects to the bottom of the side push-pull structure.

[0005] The bottom load-bearing structure can be formed by bending pipes, with the first and last ends welded together, and then ground smooth. Alternatively, the bottom load-bearing structure can be formed by welding multiple sections of pipe together, with adjacent sections welded together, and then ground smooth.

[0006] The side push-pull structure can be formed by bending tubing. The side push-pull structure is U-shaped as a whole, and the two ends are connected to the bottom load-bearing structure through triangular connectors.

[0007] The triangular connector not only connects the bottom load-bearing structure to the side push-pull structure, but also provides stable support for the side push-pull structure.

[0008] The connector passes upwards from the bottom of the bottom load-bearing structure through the triangular connector and connects to the bottom of the side push-pull structure. The connector is hidden in the frame, which helps to make the frame surface smooth and flat, as well as aesthetically pleasing.

[0009] The side push-pull structure uses tubular fittings. A connecting block is embedded at the bottom of the side push-pull structure. The connecting block has a connecting hole. The upper end of the triangular connector has a connecting protrusion. The triangular connector has a connecting through hole from bottom to top. The connecting through hole passes through the connecting protrusion. The connector passes through the connecting through hole from bottom to top and connects with the connecting hole.

[0010] The bottom load-bearing structure features a bent structure, and the bottom of the triangular connector conforms to and cooperates with this bent structure. In this way, the triangular connector can be stably mounted on the bottom load-bearing structure, contributing to the stability of the entire frame.

[0011] Alternatively, the side push-pull structure is provided with a pin hole in which a pin fits. The pin passes through the connecting block and fixes the connecting block in the side push-pull structure.

[0012] The roller seat has embedded studs, and the bottom load-bearing structure has a connecting seat with threaded holes for screwing the studs. The connecting seat can be fixed to the bottom of the bottom load-bearing structure by welding, and the roller seat can be directly installed on the bottom load-bearing structure by screwing the studs into the threaded holes, making installation and disassembly convenient.

[0013] As an improvement, the side push-pull structure is equipped with a reinforcing member, which can be fixed to the side push-pull structure by welding.

[0014] This utility model has the following technical effects:

[0015] First, the bottom load-bearing structure, as well as the side push-pull structure and handlebars, all adopt an integrated structure, which helps to improve the smoothness and flatness of the frame surface and is also aesthetically pleasing.

[0016] Secondly, the triangular connector connects the bottom load-bearing structure and the side push-pull structure, making the frame stable as a whole; the triangular connector connects the bottom load-bearing structure and the side push-pull structure through a hidden connector, making the frame surface smooth and flat, and also aesthetically pleasing.

[0017] Third, the rollers are installed at the bottom of the load-bearing structure using a screw connection, making installation and disassembly convenient. Attached Figure Description
