Detailed Description

The invention will be further described with reference to the drawings and the following examples, but the scope of the invention is not limited thereto.

As shown in fig. 1 and 2, the luggage case comprises a case body 1 and universal wheels 4, wherein the case body 1 comprises a luggage case cover 2 and a pull rod 3; the bottom of the box body 1 is provided with a groove 6, a universal wheel 4 is arranged in the groove 6, and the universal wheel 4 can be folded and then placed in the groove 6.

As shown in fig. 3 and 4, the connecting piece 5 is installed in the groove 6, the connecting piece 5 comprises a straight round pipe and a semicircular pipe, the straight round pipe and the semicircular pipe are arranged perpendicularly, the straight round pipe of the connecting piece 5 is connected with the bottom of the groove 6, a guide groove is formed in the straight round pipe of the connecting piece 5, a pin 10 is slidably installed in the guide groove, the pin 10 is installed on the connecting shaft 9 of the universal wheel 4, the universal wheel 4 can integrally move up and down along the guide groove, the universal wheel can also rotate along with the pin 10, and when the universal wheel 4 is positioned at the tail end of the guide groove, the universal wheel 4 rotates around the pin 10, so that the connecting shaft 9 is positioned in the semicircular. The fixing and positioning device is used for fixing the universal wheel 4 in the groove 6 after being folded.

The fixed positioning device is a magnetic fixing device, and the universal wheel 4 can be adsorbed in the groove 6 after being folded through magnetism. The magnetic fixing device comprises at least one pair of a first magnet 7-1 and a second magnet 7-2, the universal wheel 4 and the groove 6 are respectively provided with the first magnet 7-1 and the second magnet 7-2, and the first magnet 7-1 and the second magnet 7-2 can be adsorbed together after the universal wheel 4 is folded, so that the universal wheel 4 is fixed in the groove 6.

As the first magnet 7-1 and the second magnet 7-2 can cause the magnetism to be reduced due to the magnetic attenuation or dust adhered on the surface of the magnets in the process of dragging the luggage case in the using process, the fixed positioning device is an elastic locking device, as shown in fig. 6, the elastic locking device comprises a steel ball 8-2 and a spring 8-1, a threaded hole is arranged on the connecting shaft 9, one end of the threaded hole 8 is a taper hole, the steel ball 8-2 is placed in the taper hole, the other end of the threaded hole is provided with a plug, and the spring 8-1 is arranged between the steel ball 8-2 and the plug and used for enabling the steel ball 8-2 to protrude out of the taper hole; the connecting piece 5 is provided with a limiting hole 8-3, and the connecting shaft 9 rotates in the connecting piece 5 instead, so that the steel ball 8-2 is clamped in the limiting hole 8-3.

In order to prevent the universal wheel 4 from moving up and down in the guide groove in the normal walking process, a magnet 11 is arranged in the connecting piece 5 and used for adsorbing the connecting shaft 9 of the universal wheel 4 which is not in a folded state.

The working process is as follows:

as shown in fig. 7, the pin 10 is positioned at the uppermost end in the guide groove, and the connecting shaft 9 of the universal wheel 4 is attracted by the magnet 11; at the moment, the universal wheels 4 are exposed out of the grooves and can freely rotate at three hundred sixty degrees, so that the normal walking of the luggage case is realized. As shown in fig. 8 and 9, the connecting shaft 9 is moved downward along the guide groove by an external force, when the pin 10 is located at the lowest end in the guide groove, the connecting shaft 9 can be turned over around the pin 10 into the semicircular tube, and the first magnet 7-1 and the second magnet 7-2 can be attracted together, so that the universal wheel 4 is fixed in the groove 6. Meanwhile, the steel ball 8-2 is clamped in the limiting hole 8-3 by rotating in the connecting piece 5 through the connecting shaft 9. Like this through making the universal wheel fold and receive in the suitcase bottom, realize that the suitcase receives great impact and causes the damage because of the universal wheel in handling. Meanwhile, the universal wheels can be folded before twisting, so that the physical strength is saved.

The connecting piece 5 is not arranged at the center of the upper surface of the universal wheel 4, but is deviated to one side to ensure the stability of the luggage case in the pushing process.

When taking a subway, the universal wheels can be folded at the bottom of the luggage case, so that rolling friction is changed into sliding friction, and the luggage case is prevented from moving under the influence of inertia. When taking a subway, the friction plates are arranged around the groove 6, so that the sliding friction force can be increased, and the bottom of the luggage case can be protected.

The embodiment is a preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and any obvious improvement, replacement or modification which can be made by those skilled in the art without departing from the essence of the present invention belongs to the protection scope of the present invention.
