Problems solved by technology

However, because vehicles such as buses accelerate, decelerate and start and stop from time to time, and the friction between the casters and the ground is small, the suitcases are often slippery on the bus and are not easy to carry.

Abstract

The invention discloses a traveling case with a negative pressure skid-preventing mechanism. The traveling case comprises a traveling case basic structure composed of a case box, a case cover, a pull rod and trundles, and a skid-preventing mechanism composed of a sucker, a draw tube, an air tube, a locking ball, a spring, an air bag and a deflation plug screw, wherein the skid-preventing mechanism is provided with a draw tube capable of moving up and down straightly on a pull rod fixing part, the air tube is installed in the draw tube, and the sucker is mounted at the lower end of the air tube. A movement locking mechanism is mounted on the side surface of the draw tube, the draw tube can move up and down after overcoming the force of the locking spring, and after the draw tube moves in place, the locking ball plays limiting and locking effects. According to the skid-preventing mechanism, the air bag and the air tube are matched in the sucker to form negative pressure, and the sucker is fixed on the ground by utilizing atmospheric pressure, and the traveling case is prevented from sliding on a bus or other vehicles. The deflation plug screw in the mechanism is used for balancing pressure inside and outside the sucker so that the sucker is moved away from the ground.

Description

technical field [0001] The invention belongs to the technical field of negative pressure, and mainly relates to a device for increasing friction by using atmospheric pressure. Background technique [0002] When traveling, it is often necessary to carry a trolley suitcase. The casters at the bottom of the suitcase are beneficial to reduce the friction between the suitcase and the ground, so that the suitcase can be pushed or dragged with less force. However, when carrying a suitcase to take a bus or other means of transportation, the suitcase is placed horizontally on the ground and takes up a lot of space, so generally the suitcase will be placed vertically on the ground. However, because vehicles such as buses can accelerate, decelerate and start and stop from time to time, and the friction between the casters and the ground is relatively small, the suitcase is often slippery on the bus and is not easy to carry. Contents of the invention [0003] The purpose of the prese...
