Description

Technical Field

[0001] The utility model relates to the technical field of bags and suitcases, in particular to a trolley case. Background Art

[0002] A trolley case is a suitcase with a trolley and wheels. It is widely used because of its convenience. At the same time, trolley cases are also divided into single-tube trolleys and double-tube trolleys because of the trolley on the case. The tube of the trolley is also divided into square tubes and round tubes, which are convenient for dragging while walking, greatly reducing the burden. Trolley cases can be carried by hand or dragged. The wheels of the trolley cases we usually use are basically located at the bottom of the case, but modern people have designed a new form of trolley case, which is designed into a cylindrical shape, and the wheels are completely wrapped outside the case. This roller design allows this trolley case to better adapt to different terrains, such as directly pulling the case to go up and down stairs easily.

[0003] For example, the authorization announcement number "CN205884913U" is a trolley case, which saves energy when going up and down stairs, and the small wheels on the case do not cause inconvenience when pulling the case. However, when placing the trolley case on the luggage rack of a vehicle, if one side of the small wheels on the case is accidentally placed on the luggage rack, the small wheels on the case will reduce friction, causing the trolley case to slide, posing a safety hazard; the small wheels on the case take up space, causing the luggage to be stacked unevenly when stacking.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-4 A trolley case includes a trolley case body 1, and both sides of the lower surface of the trolley case body 1 are provided with multiple hidden grooves 2 for accommodating rollers 14. The inner walls of the multiple hidden grooves 2 are provided with first fixed blocks 3, and the outer surfaces of the multiple first fixed blocks 3 are sleeved with first rotating blocks 4. The surfaces of the multiple first rotating blocks 4 are provided with first through holes 5, and the inner walls of the first through holes 5 are connected with the first fixed blocks 3 by interference fit. The friction between the first fixed blocks 3 and the inner walls of the first through holes 5 can make the first rotating blocks 4 rotate to a specified position. The lower ends of the multiple first rotating blocks 4 are provided with first connecting blocks 6, and the lower ends of the multiple first connecting blocks 6 are provided with conversion blocks 7. The multiple conversion blocks 7 are provided with conversion cavities 8 inside, and the multiple conversion cavities 8 are provided with limit blocks 9 inside, so that the limit blocks 9 can rotate inside the conversion cavities 8, so that the rollers 14 can achieve the effect of universal wheels. A second connecting block 10 is provided on the lower surface of the multiple limit blocks 9, the lower ends of the multiple second connecting blocks 10 penetrate the lower inner wall of the conversion cavity 8 and are provided with a second fixed block 11, the surfaces of the multiple second fixed blocks 11 are provided with a second through hole 12, the insides of the multiple second through holes 12 are provided with a second rotating block 13, and rollers 14 are provided at both ends of the multiple second rotating blocks 13, and the rollers 14 can rotate along the inner wall of the second through hole 12.

[0020] The intersections of adjacent surfaces of the suitcase body 1 are provided with first reinforcement strips 15. The first reinforcement strips 15 play a role in reinforcing the suitcase body 1, and prevent the intersections of adjacent surfaces from colliding with walls and stairs when the suitcase is used to go upstairs.

[0021] The upper and lower surfaces of the trolley case body 1 are both provided with a plurality of second reinforcement strips 16. The second reinforcement strips 16 can play a role in reinforcing the trolley case and also play a role in preventing slipping.

[0022] A plurality of anti-skid bumps 17 are disposed on the surfaces of the second reinforcement strips 16 on one side away from the luggage body 1. The anti-skid bumps 17 further enhance the friction between the luggage and the contacted surface.

[0023] The inner walls of the multiple hidden grooves 2 are provided with groove reinforcement blocks 18. The groove reinforcement blocks 18 play a role in reinforcing the hidden grooves 2.

[0024] A plurality of covering blocks 19 are provided on the surface of the trolley case body 1, and the plurality of covering blocks 19 correspond to the hidden grooves 2 one by one. The covering blocks 19 are arranged on the side of the hidden grooves 2, and a first pasting block 20 is provided on the surface of the covering block 19 close to the hidden grooves 2. A plurality of second pasting blocks 21 are provided on the surface of the trolley case body 1, and the plurality of second pasting blocks 21 correspond to the plurality of first pasting blocks 20 one by one. When the rollers 14 are hidden, the first pasting blocks 20 and the second pasting blocks 21 are pasted, and the covering blocks 19 play a role in shielding dust and making the appearance beautiful.

[0025] Working principle: When the suitcase is carried upstairs, the first adhesive block 20 is separated from the second adhesive block 21 by first lifting the cover block 19, and then the roller 14 is rotated along the first fixed block 3, so that the roller 14 can roll on the stairs, saving the user's physical strength. By rotating the roller 14, the first rotating block 4 is rotated along the first fixed block 3, and the roller 14 is hidden in the hidden groove 2. When the suitcase is placed on the luggage rack of a vehicle, friction is generated between the surface of the case and the luggage rack, so that the suitcase will not slide, ensuring the safety of the suitcase; the roller 14 carried by the case is hidden in the hidden groove 2, does not take up space, and does not cause the suitcases to be stacked in an untidy manner.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
