Description

Technical Field

[0001] This utility model relates to the field of luggage technology, specifically to a convenient luggage. Background Technology

[0002] A suitcase, also known as a travel case or rolling suitcase, is usually used to store clothing, personal care products, and souvenirs needed for a trip.

[0003] A search revealed that patent application CN201921871858.X discloses a portable compressible suitcase, comprising an outer box and an inner box. Both the outer and inner boxes are square structures made of rigid materials and have a leather layer on the outside. The outer box is hollow inside, forming an outer chamber with an opening at the top. The inner box fits into the outer chamber through the opening. The inner box is also hollow inside, forming an inner chamber with an opening on the side. A double door is hinged to the opening at the hinge. A movable pull rod is mounted on the outer box on the side opposite to the double door. The pull rod is mounted on a pull rod base, which is fixed to the outer box. A baffle is provided at the top of the inner box, the size of which matches the size of the outer box. Casters are provided at the bottom of the outer box.

[0004] Although this portable compressible suitcase is more convenient to use because it has an inner compartment that can move up and down, it is still somewhat inconvenient to use. To retrieve items from the inner compartment, the inner compartment must be pulled out from the outer compartment and then secured by inserting a positioning pin into a positioning hole before the double doors of the inner compartment can be opened.

[0005] Therefore, we propose a convenient and easy-to-use suitcase. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a convenient suitcase that solves the problem that the existing device requires the inner box to be pulled out from the inside of the outer box in order to retrieve the items, which is quite troublesome to use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a convenient suitcase, comprising a main body, a connecting frame hinged to the opening of the main body via a first hinge, a main cover connected to the connecting frame via a second hinge, the main body and the connecting frame being locked together by a first mechanical lock fixedly installed on the side of the connecting frame, the connecting frame and the main cover being locked together by a second mechanical lock fixedly installed on the side of the main cover, a secondary body fixedly installed on the side of the main body away from the connecting frame, a secondary cover hinged to the opening of the secondary body via a third hinge, and the secondary cover and the secondary body being locked together by a third mechanical lock fixedly installed on the side of the secondary cover.

[0008] Preferably, the main cover is embedded inside the second hinge, and the size of the main cover matches that of the second hinge. Embedding the main cover inside the second hinge facilitates the opening and closing of the main cover and also helps the main cover to seal the opening of the second hinge.

[0009] Preferably, a lifting handle is fixedly installed in the middle of the top surface of the main body, and a rubber sleeve is fitted in the middle of the lifting handle. The lifting handle facilitates lifting the main body, and the rubber sleeve can increase the friction between the lifting handle and the human hand, preventing the hand from slipping out when holding the lifting handle.

[0010] Preferably, the secondary housing is located in the middle of the side of the main housing, and a movable pull rod is fixedly installed on the top surface of the secondary housing. The movable pull rod allows the main housing to be adapted to people of different heights, and it is also convenient to push or pull the main housing.

[0011] Preferably, four omnidirectional wheels are fixedly installed at the four corners of the main box. The omnidirectional wheels can move the main box forward by rolling on the ground, which reduces the physical exertion when using the main box.

[0012] Preferably, the corners of the main body are all rounded. The rounded corner design can prevent the corners of the main body from coming into contact with the human body during use, thus avoiding injury.

[0013] This utility model provides a convenient suitcase. It has the following advantages:

[0014] 1. This convenient suitcase allows you to place frequently used items such as power banks, data cables, and wallets inside the secondary compartment. When you need to access the items inside the secondary compartment, you can simply open the third mechanical lock to lift the secondary cover and easily retrieve the items inside.

[0015] 2. This user-friendly suitcase allows the main lid to be opened separately by unlocking the second mechanical lock, or the connecting frame and the main lid to be opened simultaneously by unlocking the first mechanical lock. Since the direction in which the main lid is opened separately is opposite to the direction in which the main lid and the connecting frame are opened simultaneously, it is convenient for users with different dominant hands to open the main suitcase from two directions. When the main suitcase needs to be opened, there is no need to deliberately adjust the orientation of the main suitcase, reducing the user's operation steps and improving the convenience of using the main suitcase.
