Trunk draw-bar trolley capable of realizing high-intensity folding

Abstract

The invention discloses a trunk draw-bar trolley capable of realizing high-intensity folding. The trunk draw-bar trolley comprises a fixed base, first pulleys and second pulleys, wherein first clamp grooves in reverse T shapes are formed in two side surfaces of the fixed base; a telescopic base is sleeved and connected to the inner side of the fixed base; one end of a rotating shaft is fixedly provided with a fixing block; a second clamp groove is formed in in one side surface of an vertical block; an H-shaped clamp block is arranged at one side of the second clamp groove; one end of the vertical block is fixedly provided with a connecting block; a telescopic block is fixedly arranged at the inner end of a fixed sleeve; the top end of the telescopic block is fixedly connected with an armrest. The vertical block, the connecting block and the fixed sleeve are made of titanium alloy materials; meanwhile, the load bearing capability of components of the vertical block, the fixed sleeve andthe like can be effectively enhanced by using the H-shaped structural design of the vertical block, the connecting block and the fixed sleeve; the easy bending and deformation can be prevented, so that the service life of the trunk draw-bar trolley is effectively prolonged; the practicability of the trunk draw-bar trolley is enhanced.

Description

technical field [0001] The invention relates to a trolley, in particular to a luggage trolley capable of being folded with high strength. Background technique [0002] As we all know, when carrying suitcases, it is often necessary to use a trolley for transportation, but because the strength of the trolley is not strong enough, and the pressure bearing capacity is not strong, it is easy to cause the trolley to break during the use of the trolley, making the trolley unable to continue to use However, the trolleys used in the market generally cannot be folded, so that the trolleys need to occupy a large amount of area when they are stored, which makes it inconvenient to use and store the trolleys. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a high-strength folding luggage trolley, which can enhance the strength of the present invention and prolong the service life of th...
