Description

Technical Field

[0001] The utility model relates to the field of luggage accessories, and particularly relates to a luggage pull rod which can prevent deformation. Background Art

[0002] A pull rod luggage, also known as a trolley case, is a kind of luggage with a pull rod and rollers. It is widely loved by people because of its convenient use. The pull rod usually includes rod bodies which are arranged oppositely and parallel to each other. Each rod body includes an outer rod and an inner rod telescopically arranged in the outer rod. A holding handle is connected between one ends of the tops of the inner rods. The outer rod is hidden in the box body. When in use, after pulling out the inner rod, hold the holding handle by hand and tow the luggage. However, when not towing, if the inner rod is not reset and stored, the inner rod is always exposed to the external environment. Once the luggage is overturned or dropped from a height and the pull rod is impacted, the inner rod is liable to deform and cannot be used normally. Summary of the Invention

[0003] The technical problem to be solved by the utility model is aimed at the deficiencies of the above-mentioned prior art,

[0004] and provides a luggage pull rod which can prevent deformation to prevent deformation from affecting normal use.

[0005] To achieve the above object, the utility model provides the following technical solution: a luggage pull rod which can prevent deformation, including rod bodies which are arranged oppositely and parallel to each other. Each rod body includes an outer rod and an inner rod telescopically arranged in the outer rod. A holding handle is connected between one ends of the tops of the inner rods. The feature is that: the inner rod includes an upper end part, an elastic part and a lower end part which are arranged in sequence from top to bottom. The elastic part has elasticity. The elastic part is fixedly connected with the upper end part and the lower end part respectively. The holding handle is arranged between one ends of the two upper end parts far away from the elastic part. A limiting device for preventing the lower end part from coming out is arranged between the lower end part and the outer rod.

[0006] A further setting of the utility model is that: a plugging groove which is adaptively plugged with the elastic part is coaxially opened at one end below the upper end part and one end above the lower end part. Two ends of the elastic part are respectively plugged in the corresponding plugging grooves. The upper end part and the lower end part are respectively transversely provided with positioning holes passing through the plugging grooves and the elastic part. A positioning rod is arranged in the positioning holes.

[0007] A further setting of the utility model is that: two ends of the elastic part placed in the plugging groove part and the inner wall of the plugging groove are fixed by glue.

[0008] A further setting of the present utility model is as follows: on the outer surface of one end below the upper end portion, upper mounting grooves are oppositely provided; on the outer surface of one end above the lower end portion, lower mounting grooves are oppositely provided; one upper mounting groove corresponds to one lower mounting groove; a support plate is connected between each corresponding upper mounting groove and lower mounting groove; magnets are embedded in both the upper mounting groove and the lower mounting groove; adsorption blocks adsorbed to the magnets are respectively provided at both ends of the support plate; and the thickness of the support plate is less than the depth of the lower mounting groove or the upper mounting groove.

[0009] A further setting of the present utility model is as follows: the limiting device includes limiting blocks oppositely arranged on the inner wall of the outer rod; the upper end portion and the side wall of the lower end portion are provided with adapted sliding grooves; and limiting ridges are provided at the bottom of the sliding grooves.

[0010] For the present utility model with the above characteristics: when the inner rod is impacted, the elastic part deforms to absorb the impact force, and after the elastic part deforms, it returns to its original state, so that the inner rod maintains its original state. The support plate is embedded in the upper mounting groove and the lower mounting groove through the magnet and the adsorption block to support part of the elastic part, which is convenient for towing. Since the support plate is installed by magnetic adsorption, when it is impacted, the support plate falls off, and the elastic part deforms to absorb the impact force. After the elastic part resets, the dropped support plate can be put back to the predetermined position again.

[0011] The beneficial effect of the present utility model is that the elastic part deforms to absorb the impact force, and after the elastic part deforms, it returns to its original state, so that the inner rod maintains its original state and prevents the inner rod from deforming.

[0012] The present utility model will be further described in detail below with reference to the drawings and embodiments. Description of the Drawings
