[0002] An electronic wiring harness is a bridge of communication between two or more isolated electronic circuits, which enables the flow of current and realizes the functions of various electronic components. It is an indispensable component in various electrical and electronic equipment. During the processing of electronic wiring harnesses, transport carts are generally used to carry and transport the wiring harnesses.

[0003] According to a transport cart for wire harness processing with publication number CN212074105U, the transport cart includes a transport cart body, the transport cart body includes an adjustment mechanism and a fixing mechanism, the adjustment mechanism is arranged on the top of the transport cart body, the fixing mechanism is arranged on both sides of the transport cart body, and baffles are arranged at the bottom of the adjustment mechanism relative to both sides of the transport cart body, and an armrest is arranged on one side surface of the adjustment mechanism.

[0004] The above patent mentions the technical content that the fixing mechanism is arranged on both sides of the transport cart body. The wire harness is placed through the fixing mechanism on both sides of the transport cart body, and then the wire harness is transported. Since the wire harness is composed of metal wires, rubber sleeves, metal connectors and sheaths, it is heavy. When the wire harness on one side of the transport cart body is removed, the wire harness on the other side is too heavy, making it difficult for the transport cart to maintain balance. Therefore, the wire harness transport cart is prone to tipping over, affecting the transported wire harness. Utility Model Content

[0007] Preferably, both sides of the two groups of movable seats are connected with brackets through rotating shafts, a group of connecting shafts is inserted and sleeved between each two groups of brackets, and the bottom ends of the two groups of connecting shafts are provided with supporting wheels.

[0008] Preferably, the bottom end of the base is located on the outside of the second connecting frame and is equipped with four sets of wheels via bolts, and the bottom end of the base is located on one side of the servo motor and is equipped with a power supply via bolts.

[0009] Preferably, both ends of the support plate are welded with a hanging bracket, and the outer wall of the support plate is welded with a protective plate on the outer side of the hanging bracket.

[0010] Preferably, an axle seat is welded to the top of the fixed plate, and the axle seat is connected to the first connecting frame through a rotating shaft. A handle is sleeved through the interior of the first connecting frame, and a sliding groove is provided on the inner side of the first connecting frame. A sliding frame extending to the outside of the first connecting frame is provided on the inner side of the sliding groove.

[0011] Preferably, the inner side of the slide is connected with a connecting rod via a rotating shaft, the outer wall of the bottom end of the connecting rod is sleeved with a connecting pipe welded to a fixing plate, and the bottom end of the connecting rod is located inside the connecting pipe and a spring is arranged.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the harness transport cart is stably supported, the servo motor and the bidirectional threaded rod drive the moving seat to move, so that the distance between the two groups of moving seats is gradually shortened, and the moving seat drives the bracket and the connecting shaft to move through the rotating shaft, and the bracket and the connecting shaft drive the supporting wheel to move to the outside of the transport cart. The bracket, the connecting shaft and the supporting wheel increase the force surface between the transport cart and the ground, thereby stably supporting the transport cart to prevent the transport cart from tipping over due to the excessive weight of the single-sided wire harness, thereby achieving the role of protecting the transport cart.

[0014] 2. When the wire harness transport cart is feeding, the first connecting frame is rotated downward with the axle seat as the axis through the handle, the handle drives the slide to rotate, the slide pushes the connecting rod to descend through the rotating shaft, the connecting rod pushes the spring to compress and deform, the handle and the first connecting frame are rotated downward, so that the height of the handle is easy to adjust, which is convenient for users of different heights and body shapes to use, and at the same time, it is convenient for the operator to pull the wire harness transport cart to move through the handle, the first connecting frame, the axle seat and the fixed plate, thereby effectively preventing the wire harness transport cart from hindering the operator's cart action.
