Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of luggage pull rod, specifically to a polyethylene composite luggage pull rod. BACKGROUND

[0002] The luggage pull rod is an important component of the luggage, which is a metal pipe connecting the box body and the bottom pulley of the box, usually in the back or side of the luggage. The pull rod has multi-section telescopic function, and the user can extend or retract the pull rod to the appropriate height according to the need, and easily push and pull the luggage through the pulley system. It mainly plays the role of supporting and pulling in the luggage, making the luggage more convenient in the process of carrying. Defects: at present, the pull rod usually needs to be pressed by the user before it can be retracted, but if the luggage is too much and the hand is not convenient, the process of pressing the pull rod down will cause inconvenience. In order to solve the above-mentioned defects, the existing technology (application number: 202122041948.X, granted announcement date: 2022-01-14 of Chinese patent) discloses a luggage pull rod capable of automatic reset. The function rods slide in the corresponding function sleeves, which is convenient to pull out the function rods when using the luggage, and convenient to store when not using the luggage. The supporting spring can provide a pushing force to the clamping rod towards the function rod. When the length of the function rod is adjusted, the clamping rod can be inserted into the corresponding clamping groove, which is convenient to use the function rod and prevents the function rod from being retracted into the function sleeve. The user can control the foot plate to move towards the ground, and at this time the two clamping rods can be pulled out of the clamping groove by using the traction rope. If the function rod does not receive a pulling force away from the function sleeve, the function rod can return to the function sleeve under the action of gravity, and the clamping rod continues to resist between the function rods under the action of the elastic force of the supporting spring, so as to prevent the function rod from sliding out of the function sleeve during use.

[0003] The existing technology is to pull out the function rod and move the luggage by the function rod, but when pulling the luggage, the user needs to bear part of the weight of the luggage due to the inclined state of the luggage, which makes it more laborious to drag the luggage. Moreover, after long-term use, the surface of the luggage pull rod is worn and deformed, which causes the luggage pull rod to be unable to extend and retract smoothly, thereby affecting the use. Therefore, we propose a polyethylene composite luggage pull rod to solve the above problems. UTILITY MODEL CONTENTS
