Description

Technical Field

[0001] This utility model relates to the field of luggage technology, and in particular to a luggage handle assembly. Background Technology

[0002] A rolling suitcase is a type of luggage equipped with a pull handle and wheels. It is widely used due to its convenience. Rolling suitcases are further categorized by the pull handle: single-tube and double-tube handles are available. The handle tubes also come in square and round shapes to facilitate dragging while walking, greatly reducing the burden. Rolling suitcases can be carried by hand or pulled. While the wheels of most rolling suitcases are located at the bottom, modern designs have created a new type of rolling suitcase with a cylindrical shape and wheels entirely encased on the outside. This roller design allows the suitcase to better adapt to different terrains; for example, it can be easily pulled up and down stairs.

[0003] The pull rod is one of the core components of a suitcase. Chinese patent CN220937089U discloses a suitcase pull rod assembly, including a bracket, a truss, a telescopic rod, and a cover assembly. The truss is fixedly connected to the surface of the bracket, the telescopic rod is slidably connected to the inner wall of the bracket, a handle is fixedly connected to the surface of the telescopic rod, and a button is provided on the surface of the handle. The cover assembly is located on the side surface of the handle and includes a positioning frame, which is fixedly connected to the side surface of the handle. A rotating hole is opened on the side surface of the positioning frame, and a rotating shaft is rotatably connected to the inner wall of the rotating hole. A protective cover plate is fixedly connected to the surface of the rotating shaft, and a gripping block is fixedly connected to the side surface of the protective cover plate. This utility model, by setting the cover assembly and auxiliary components, can cover and protect the button of the pull rod assembly, thereby reducing the problem of accidental button activation and unlocking of the locking mechanism when the user holds the pull rod assembly, and further improving the stability of the pull rod assembly in use.

[0004] When people use rolling suitcases, they often carry small bags to store personal items. The aforementioned patent has a single function and cannot hang and store these small bags, causing people to have to hold the handle with one hand and lift the small bags with the other, which is quite inconvenient. Therefore, in view of the above situation, there is an urgent need to develop a multifunctional luggage handle component that can easily hang small items to improve the overall carrying capacity, in order to overcome the shortcomings of current practical applications and meet current needs. Utility Model Content

[0005] The purpose of this utility model is to provide a luggage handle assembly to solve the problems mentioned in the background art.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A luggage handle assembly includes a lower handle, an upper handle, a connecting sleeve, a hooking mechanism, a limiting pin, and a pushing mechanism. The upper handle is slidably mounted inside the lower handle, extending to its exterior. Two limiting pins penetrating the lower handle are installed inside the upper handle. A compression spring is fixed to one end of each limiting pin, and the compression spring is fixedly installed inside the upper handle. The limiting pins slide in contact with the lower handle and the upper handle, respectively. The lower handle passes through two connecting sleeves, which are welded to the lower handle. A hooking mechanism is installed at the top interior of the upper handle. A pushing mechanism is installed on the lower handle, opposing the two limiting pins. The hooking mechanism includes a fixed rod, a rotating sleeve, a hooking ring, a clamping screw, and a lever. The fixed rod is welded to the top interior of the upper handle. A rotating sleeve is rotatably connected to the outside of the fixed rod. A hooking ring is welded to the front of the rotating sleeve. A clamping screw that presses against the fixed rod is installed on the rotating sleeve. Multiple levers are fixed to the upper end of the clamping screw.

[0008] Preferably, the lower rod body, upper rod body, and connecting sleeve are all made of aluminum alloy.

[0009] Preferably, both ends of the connecting sleeve are provided with mounting holes for screws to pass through.

[0010] Preferably, the pushing mechanism includes a connecting rod, a sliding sleeve, an operating push plate, and a thrust rod. The connecting rod is welded and fixed to the lower rod body. Two sliding sleeves are slidably installed on the connecting rod. An operating push plate is fixed on the upper side of each sliding sleeve. A thrust rod is fixed at the upper end of each operating push plate. The thrust rod is aligned with a limiting pin.

[0011] The beneficial effects of this utility model are as follows: When using this bag handle assembly, if small items need to be carried, the lever is turned by hand to rotate the clamping screw, loosening it. Then, the rotating sleeve and hook ring are rotated, causing the hook ring to rotate to the front of the upper handle. Small items can then be hung on the hook ring. When not in use, the hook ring is rotated back into the upper handle, reducing the overall volume occupied. Additionally, pushing the operating push plate by hand moves the push rod, pushing the limit pin into the lower handle. Then, pressing the upper handle down retracts it. In summary, this utility model offers multiple functions, facilitating the hanging of small items and improving overall carrying capacity. Attached Figure Description
