[0016] As a further preferred embodiment, the wheel mounting seat 4 includes a forward wheel seat 41 and a locking wheel seat 42. The wheel assembly 3 includes a forward wheel 31 and a locking wheel 32. The forward wheel seat 41 has a first insertion seat 411 at its front end and a through wheel pin hole 412 at its rear end. The forward wheel 31 is rotatably mounted to both ends of the forward wheel seat 41 via a wheel pin. The locking wheel seat 42 includes a brake base 421, a brake paddle 422, and a wheel pin 423. The brake base 421 has a rivet hole 4211 for rotatably connecting with the brake paddle 422, a wheel pin hole 4212 for mounting the wheel pin 423 along its thickness direction, two sets of locking holes 4213 spaced apart, and a second insertion seat 4214. The brake paddle 422... The system includes a paddle body 4221 and a pressure plate 4222 located at the rear end of the paddle body 4221. The front end of the paddle body 4221 is provided with a mounting hole 42211 and a locking protrusion 42212, and the lower end is provided with a locking rod 42213. A rivet 424 is inserted between the rivet hole 4211 and the mounting hole 42211 to enable the brake paddle 422 to rotate on the brake base 421. The locking protrusion 42212 can be embedded in any set of locking holes 4213. The wheel pin 423 is rotatably assembled in the wheel pin hole 4212. The locking wheel 32 is rotatably sleeved on both ends of the wheel pin 423, and its inner side is provided with multiple sets of snap-fit ​​grooves 321 arranged in a ring array. The locking rod 42213 can be inserted into any set of adjacent snap-fit ​​grooves 321.

[0017] Specifically, in the brake structure design of the locking wheel seat 42, two sets of locking holes 4213 cooperate with the locking protrusion 42212 of the brake paddle 422 to accurately position the start and stop position of the brake paddle; at the same time, the multiple sets of locking grooves 321 in the annular array on the inner side of the locking wheel 32 can ensure that the locking rod 42213 of the brake paddle can be quickly inserted into the adjacent locking groove to lock, regardless of the rotation angle of the wheel. This is suitable for loading heavy objects or parking on slopes, as it can completely lock the wheel, prevent the bag cart from accidentally sliding, and improve the safety of use.

[0018] As a further preferred embodiment, both the first plug-in socket 411 and the second plug-in socket 4214 are provided with locking paddles 51, and the lower ends of the first support rod 121 and the second support rod 122 are provided with mounting posts 61.

The locking slots 62 are correspondingly provided with the locking paddles 51 to achieve locking.

[0019] Specifically, the locking lever 51 inside the first connector 411 and the second connector 4214, together with the mounting post 61 at the lower end of the first / second support rod 121 / 122 and the locking slot 62, form a "locking upon insertion and unlocking upon levering" structure. During installation, simply align the mounting post 61 with the connector and insert it. The locking lever 51 will automatically engage with the locking slot 62 under its own elasticity, without the need for additional tools. During disassembly, simply move the locking lever 51 to unlock the mounting post, making disassembly and assembly simple.

[0020] As a further preferred embodiment, a lateral support bracket 7 is also included, which is rotatably connected to the support bracket 12.

[0021] Specifically, the lateral support bracket 7 is rotatably connected to the support bracket 12. When unfolded for use, the lateral support bracket can be extended outwards to form a support together with the base bracket 11 and the support bracket 12. When the bag cart is loaded with irregular heavy objects or subjected to force on one side, the lateral support bracket can distribute the lateral pressure and prevent the cart frame from tipping over due to uneven force. The lateral support bracket 7 can be folded inwards around the connection point with the support bracket 12. When folded, it can be joined with the support bracket 12 and completely fit the main body of the cart frame 1 without adding extra volume to the folded bag cart.
