Suitcase with rotatable retractable draw bar

Abstract

The invention relates to the field of suitcase products and in particular relates to a suitcase with a rotatable retractable draw bar. The suitcase comprises a case body which is horizontally arranged, wherein the case body is provided with a case body groove; outer pipes are embedded into the case body groove; an inner pipe is embedded into each outer pipe; one end of each inner pipe is connectedwith an inner pipe handle; each inner pipe handle is provided with a convex bag; a groove is formed in in one side of each inner pipe handle; an outer pipe handle covers each outer pipe. The invention aims at providing the suitcase with the rotatable retractable draw bar and common problems of the retractable draw bar that a retractable process is hindered and the inner space of the case body isoccupied can be effectively solved; the outer pipes are arranged at the part of the case body groove, so that the problem that the retraction of the retractable draw bar is hindered, caused by the fact that the retractable draw bar is excessively squeezed by objects in the case body to be deformed, is improved; the convex bags on the two inner pipe handles are tightly combined with the groove to realize dual protection, and interlocking is formed under linear power of the inner pipes, so that the suitcase is more convenient to use.

Description

technical field [0001] The invention relates to the field of travel case products, in particular to a travel case with a rotatable telescopic pull rod. Background technique [0002] At present, the trolleys of products such as suitcases or toolboxes on the market all use telescopic tie rods hidden inside the box body. The tube body of the tie rod in this solution protrudes inside the box body, occupying a large part of the internal space, and when the items are placed After the box body is squeezed, the tube will be deformed, the expansion and contraction of the pull rod will be blocked, causing dysfunction, shortening the service life of the pull rod to a certain extent, and also affecting the actual use experience of the suitcase or toolbox. The pull rod adopts the up and down telescopic method. Forcible force will cause the pull rod to be easily stuck. The average user will continue to use brute force, which will only make the pull rod more and more stuck. At the same tim...

Problems solved by technology

[0002] At present, the pull rods of products such as suitcases or tool boxes on the market all use telescopic pull rods hidden inside the box body. The tube body of the pull rod protrudes inside the box body, occupying a large part of the internal space Many, after the box body is squeezed, the tube will cause deformation, and the stretching of the pull rod will block, causing dysfunction, shortening the service life of the pull rod to a certain extent, and also affecting the actual use experience of the suitcase or toolbox. The traditional The pull rod is stretched up and down. Forcible force will cause the pull rod to be easily stuck. Ordinary users will continue to use brute force, which will only make the pull rod get stuck more and more. At the same time, when the suitcase or toolbox is impacted or collided , will inevitably cause different degrees of damage to the telescopic rod. The telescopic rod is easy to produce radians, bends, and deformations during the collision process, which further affects the telescopic process of the rod and shortens the service life of the rod, effectively preventing the rod from being blocked during the telescopic process. , has become a problem that the telescopic rod needs to be solved
