Abstract

A retractable traveling wheel device for a trolley case comprises a base plate, connecting shafts, a transmission rod, a motor, a battery and traveling wheels. The connecting shafts are in bilateral parallel arrangement on two lower sides of the base plate, the traveling wheels are arranged at front and rear ends of the connecting shafts, the transmission rod is horizontally arranged on the innerupper portion of the base plate, the motor is vertically arranged on the front lower side of the transmission rod in the base plate, and the battery is arranged on one side of the motor in the base plate. The base plate is in a rectangular shell structure, and four lower corners of the base plate are provided with traveling wheel grooves uniformly. By adoption of the technical scheme, the retractable traveling wheel device has advantages that due to arrangement of the traveling wheels on the rotary connecting shafts, electric lifting of the traveling wheels is realized, sliding of the trolleycase in placement is avoided while scratching damages of the traveling wheels in a transporting process are reduced, strength of the trolley case is evidently improved, and convenience is brought to auser.

Description

technical field [0001] The invention relates to the field of bag manufacturing, and discloses a telescopic traveling wheel device for a trolley suitcase. Background technique [0002] The trolley case is a necessity for frequent business trips. It is deeply loved by everyone for its convenience and safety. For the convenience of walking and dragging, the existing trolley case is usually provided with two or four universal walking wheels at the bottom of the case. It is very convenient, but the use of universal walking wheels is connected to each other. People on business trips often take high-speed rail, airplanes and other means of transportation. During transportation, due to the prominent universal walking wheels of the trolley case, the wheels are very easy to be damaged during transportation. The light ones are scratched and crooked, and the heavy ones are directly damaged and cannot be used. On the contrary, it brings great inconvenience to the use. There are dangers ...
