Technical Field

The invention relates to the technical field of luggage cases, in particular to a waterproof luggage case convenient to drag.

Background

Luggage, also known as traveling case and trolley case, is a case that is carried when going out for placing articles, which is one type of luggage. Usually, the luggage case is used for placing clothes, personal care products and souvenirs required by the journey.

The luggage case generally adopts a pull rod and roller structure at the present stage, namely, when the luggage case is used, the pull rod is pulled out from the groove, then the luggage case is pulled by pulling the pull rod, however, when the luggage case is used in the rainy weather frequent in summer, when large accumulated water is generated on the road surface, the pulling resistance is large, and the bottom of the luggage case is soaked in water for a long time, so that the service life of the luggage case is influenced, and simultaneously the problem that the articles in the luggage case are easy to enter water is solved.

Disclosure of Invention

The invention aims to solve the problems that in the prior art, when water is accumulated on a road surface, a trunk is difficult to drag, and water is easy to enter articles in the trunk, and provides a waterproof trunk convenient to drag.

In order to achieve the purpose, the invention adopts the following technical scheme: a waterproof luggage case convenient to drag comprises a case body, wherein two wheel cavities are formed in the bottom of the case body, two symmetrical side faces of the wheel cavities are respectively provided with a connecting groove, a sliding block with the size matched with the connecting groove is connected in a sliding mode in each connecting groove, a rotating shaft is inserted in the centers of the two sliding blocks together, a roller wheel located in each wheel cavity is sleeved outside the rotating shaft, a liquid storage cavity is formed in the part, located between the two wheel cavities, of the case body, a through hole is formed in the bottom of the liquid storage cavity in a penetrating mode, a permeable membrane is connected to the through hole in a sealing mode, a sealing plate is fixedly connected to the inner wall of the liquid storage cavity in a sealing mode, a sliding plate which is connected to the side wall of the liquid storage cavity in a sealing mode;

an air flow channel is formed in the rotating shaft and penetrates through the sliding blocks at two ends of the rotating shaft, two side walls of the box body are fixedly connected with an air bag respectively, air inlets penetrating through the connecting grooves are formed in the air bag and the liquid storage cavity respectively, the size of each air inlet is matched with that of the air flow channel, an electromagnetic valve is hermetically connected to each air inlet, a conductive layer electrically connected with the sliding block is arranged in each electromagnetic valve, one side, close to each air inlet, of each sliding block is electrically connected with an external battery, and evaporated liquid with a lower boiling point is filled in each liquid storage cavity;

each connecting groove is fixedly connected with an electromagnet at the bottom, a permanent magnet is arranged at the top of each connecting groove, and the sliding block is provided with magnetism which is opposite to the same pole of the electromagnet when the electromagnet is electrified and opposite to the opposite pole of the permanent magnet

In the waterproof luggage case convenient to drag, a groove is formed at the joint of the sealing plate and the spring, and the fixed end of the spring is fixedly connected to the bottom of the groove.

Compared with the prior art, the invention has the advantages that:

1. according to the luggage case, the side wall of the case body is provided with the air bag, when the luggage case is in normal use, the air bag is in a contraction state, the roller is positioned at the bottom of the wheel cavity, the luggage case is driven to move through the roller, and the air bag can prevent the external water splashing effect when the luggage moves;

2. when water accumulates on the ground and the height of the accumulated water is large, in the prior art, the position of the roller is fixed, so that the lower part of the luggage case is partially immersed into the water, on one hand, the luggage case is hard to move due to the resistance of the water, on the other hand, the object in the luggage case is affected with damp due to the long-term immersion of the luggage case, and the like;

3. when the sliding plate is used, when the accumulated water is high, water enters the liquid storage cavity through the permeable membrane and exerts upward thrust on the sliding plate, when the sliding plate is used, the accumulated water outside and the liquid storage cavity form a communication effect, so that the sliding plate is moved upwards to the height same as the external water level by water pressure, when the water level is higher than the height of the sealing plate, the sliding plate exerts pressure on the sealing plate, and the sealing plate is made of a memory metal material and has a pressure-heat effect, namely, heat is released when the sealing plate is pressed, so that evaporated liquid in the liquid storage cavity is evaporated, and meanwhile, the sliding plate is communicated with a circuit of the electromagnet through a battery, so that the sliding block is lifted by magnetic repulsion force, and;

4. when the roller wheel contracts upwards, the sliding blocks at the two ends of the rotating shaft of the roller wheel are positioned at the high ends of the connecting grooves and are attracted by the permanent magnets, the roller wheel completely contracts into the wheel cavity, the two ends of the airflow channel are communicated with the air inlet in a matched mode, the sliding blocks are communicated with the electromagnetic valve when ascending to the position of the air inlet, at the moment, the air pressure in the liquid storage cavity is large, gasified evaporated liquid gas enters the air bag through the airflow channel, the air bag expands under the action of the gas, the size is increased, the buoyancy between the air bag and water is improved, the box body floats in the water, and people can move the luggage box only by using small force;

5. after moving down when the water level, when being less than the closing plate height, under the spring action, the slide breaks away from the connection with the closing plate, the closing plate will not be stressed this moment, and memory metal material's closing plate will absorb the heat to the stock solution chamber this moment, and make stock solution intracavity temperature drop, stock solution chamber atmospheric pressure reduces this moment, gas makes the evaporation gas reentrant the stock solution intracavity at reverse negative pressure effect in the gasbag, and the liquefaction is stored for the evaporation, and produce the magnetic attraction to the slider under the uncharged state of the electro-magnet that breaks away from the connection, make the downward resultant force that the slider received be greater than the appeal of permanent magnet, make the slider be in the least significant end again and be connected with the permanent magnet, the gyro wheel releases again this moment, make can normally drag the suitcase.
