[0018] In order to make the utility model patent purpose, technical scheme and advantage more clearly clear, the following is combined with drawing and example, and the utility model is further detailedly explained.It should be understood that the specific embodiment described here is only used to explain the utility model, and is not used to limit the utility model.

[0019] In order to explain the technical scheme described in the utility model, the following is explained by specific embodiment.

[0020] For the convenience of explanation, only part relevant to the embodiment of the utility model is shown.

[0021] Combined Figures 1-3 As shown in the figure, the logistics goods trolley framework includes bottom frame 1, and a pair of connecting seats 2 are rotatably arranged on the front and back of the bottom frame 1, walking wheels 3 are arranged on each connecting seat 2, a pair of turning assemblies are rotatably arranged on the front and back of the bottom frame 1, the turning assembly includes linkage seat 41 rotatably arranged on the bottom frame, a pair of push-pull rods 42 are rotatably arranged on the linkage seat 41, and the other end of the push-pull rod 42 is rotatably provided with connecting plate 43, the connecting plate 43 is fixed on the connecting seat 2 of the same side, and linkage rod 44 is rotatably arranged between the front and back linkage seats 41.

[0022] The logistics goods cart is a common tool for short-distance transportation of goods, and its performance directly affects the overall efficiency of logistics operation. The cart frame is an important part of the whole cart, which includes a chassis, the chassis is the basic support structure of the whole cart, a pair of connecting seats are rotatably arranged at the front and rear of the chassis, and a walking wheel is arranged on each connecting seat. The walking wheel can rotate relative to the chassis to realize the movement of the cart and provide a basis for the turning of the cart.

[0023] A pair of frames 5 are arranged on the chassis 1, and a cart box (not shown in the figure) is arranged on the frames 5. The cart box is used to carry goods, and the frames can enhance the structural strength of the chassis and improve the carrying capacity of the cart.

[0024] As a specific structure, as shown in Figures 1-2 and Figure 4 The front linkage seat 41 is provided with a connecting plate 6, the connecting plate 6 is provided with a traction seat 8 through a locking bolt 7, the traction arm 9 is rotatably arranged on the traction seat 8, the traction arm 9 is provided with a round hole, the back of the traction arm 9 on the traction seat 8 is provided with a locking seat 10, the round hole is inserted with a latch 11, the latch 11 passes through the locking seat 10, and the rear linkage seat 41 is provided with a C-shaped fixing seat 12. The fixing seat 12 is provided with a fixing shaft (obscured in the figure).

[0025] Before the cart frame is used to transport goods, the whole cart is connected with the towing vehicle through the traction arm, and the towing vehicle moves while towing the cart frame. When it is needed to fix the traction arm at the towing position of the towing vehicle, the latch is removed first, and then the traction arm can be rotated up and down and fixed on the towing vehicle. The other linkage seat is provided with a C-shaped fixing seat, and the fixing seat is provided with a fixing shaft. The fixing shaft can be used to connect with other components, and further enhance the functionality of the cart.

[0026] When the traction arm is installed at the towing position of the towing vehicle, if the towing vehicle drives straight with the cart, the walking wheels normally roll under the driving of the chassis. If the cart needs to turn during normal driving, the traction arm applies a turning force, and the traction arm drives the traction seat and the front linkage seat to rotate. The rotation of the front linkage seat is transmitted to the connecting seat through the push-pull rod, so that the connecting seat rotates, thereby realizing the turning of the walking wheels. The linkage rod between the front and rear linkage seats ensures the coordination of the turning of the front and rear pairs of walking wheels, so that the cart can turn smoothly.

[0027] Figure 2 In the specific structure, a pair of limiting slots 14 are arranged on the chassis 1 opposite to the linkage seat 41, and a pair of limiting columns 15 are arranged on the linkage seat 41, and the limiting columns 15 are located in the corresponding limiting slots 14.

[0028] In the structure, the cooperation of the limiting slot and the limiting column limits the rotation range of the linkage seat, avoids excessive rotation of the linkage seat, and guarantees the stability and safety of the trolley when turning.

[0029] In addition, as Figure 1 In the structure, the cooperation of the limiting slot and the limiting column limits the rotation range of the linkage seat, avoids excessive rotation of the linkage seat, and guarantees the stability and safety of the trolley when turning.

[0030] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
