Description

An easy-to-extend luggage pull rod with multi-section sleeve rods

technical field

The utility model relates to the technical field of pull rods for bags, in particular to an easy-to-stretch pull rod for bags with multi-section sleeve rods.

Background technique

The pull rod on the luggage is a functional part of the luggage, which is used to drag the luggage to move. At present, the common trolleys of luggage on the market are specially equipped with a trolley sleeve fixed on the luggage. The trolley can be stretched and retracted in the trolley sleeve, which is convenient for hiding when not in use. The improvement of the structure of the luggage pull rod mostly focuses on the automatic pop-up device of the pull rod, the positioning device and the arbitrary adjustment of the height of the pull rod, so as to adapt to users of different heights.

For example, Chinese patent CN2379008 discloses a pull rod device for a suitcase, which consists of a base, an outer rod and a pull rod. The base is provided with a receiving groove for assembling the outer rod. A seat is pivoted with a bolt at the end, and a spring is arranged on the block seat, which is accommodated in the outer rod and is compressed by the tension rod; the handle seat is provided with a receiving groove, and a dial hole is provided on one side of the receiving groove , there is a hook hole on the side of the storage tank, and the hook hole corresponds to the dial hole; a hook seat is arranged on the side of the handle seat, and a spring against a hook is provided inside, and the hook corresponds to the holding hole. The hook hole is hooked with the handle, and the hook is provided with a dial that can be moved to make the hook break away from the handle, and the dial is corresponding to the dial hole. The pull rod device is positioned stably, can automatically pop up to a certain height, and is convenient to use. But because the pull rod has only one joint, the height of the pull rod is fixed and cannot be adjusted as required to suit people of different heights, thus bringing inconvenience to the puller.

For this reason, Chinese patent CN202154210 discloses a kind of luggage pull rod that is easy to expand and contract, including handle, inner pull rod, outer pull rod and connecting rod, the handle is fixed on the top of the inner pull rod, the connecting rod is fixed on the top of the outer pull rod, and the inner pull rod It includes a first inner pull rod and a second inner pull rod nested in each other, the bottom of the first inner pull rod and the top of the second inner pull rod are provided with engaging components that cooperate with each other, and the top of the handle is provided with a spring button that controls the engaging components . The pull rod has two internal pull rods, so that the structure of the pull rod can be adjusted. However, the spring-controlled snap-in component makes this solution only have two inner tie rods, which cannot fully meet the user’s requirement for adjusting the length of the tie-rod, and the spring-controlled snap-in component is extremely prone to failure, making the use of the pull rod extremely difficult.
