Description

Technical Field

[0001] The utility model relates to the technical field of luggage pull rods, in particular to a luggage pull rod with a steering compensation function. Background Art

[0002] Luggage trolleys are an indispensable part of modern travel luggage. The design of the trolley makes it easy to drag the suitcase, greatly reducing the burden of carrying heavy objects. The trolley is designed with single tube and double tube. The double tube trolley is usually more stable and durable, while the single tube trolley is relatively light. In addition to the basic dragging function, modern luggage trolleys also have the function of adjusting the height to accommodate users of different heights.

[0003] When the existing luggage pull rod is turned, the user's arm is required to provide a turning force. When turning, the weight of the luggage is all pressed on the user's arm. Frequent turning will cause soreness in the user's arm. Utility Model Content

[0009] Further preferably, a pull rod is fixedly connected to the top of the inner rod, and a handle is fixedly connected to one side of the bag body.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In the utility model, by installing the compensation component, the user drags the bag body to move it by pulling the pull rod. When turning is required, the user can move and press the button on the right side of the inner rod. The button is affected by the external force and squeezes the extrusion plate to move to one side, causing the spring to deform. At this time, the trigger rod will contact the trigger switch, and the electric wheel will turn synchronously, thereby realizing the compensation function. The user's arm does not need to provide all the steering force, avoiding arm pain caused by frequent turning.

[0012] In the utility model, by installing the adjustment component, the user holds the pull rod and applies force upward. The pull rod is affected by the external force and drives the inner rod to move upward. When the inner rod moves upward, it drives the rack to move upward. When the rack moves upward, it drives the gear to rotate on the rotating shaft 1, and at the same time drives the slider to slide in the slide groove, thereby adjusting the length of the inner rod 1.
