Description

Technical Field

[0001] The utility model relates to the technical field of trolley cases, in particular to a center-mounted trolley case. Background Art

[0002] A trolley case is a type of luggage, which includes a luggage body, a telescopic handle and wheels at the bottom of the luggage. It is widely used because of its convenience in use. Suitcases have a long history, from wooden boxes and large leather suitcases that are only used to hold clothes to portable suitcases and trolley cases of various shapes today. However, during the use of current trolley cases, the telescopic handle used to drag the trolley case is usually set on one side of the case body. This arrangement of the telescopic handle makes the trolley case not stable and smooth when pushed, especially when the trolley case is loaded with heavier items, it is more inconvenient to pull it at this time. In addition, when there are only stairs, the user needs to manually carry the case upstairs, which is inconvenient to use. Therefore, we propose a mid-mounted trolley case to solve the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, a center-mounted trolley case proposed in an embodiment of the utility model comprises a left case body 1, a giving groove 13 for facilitating pulling out the handle 4 is provided on the top of the left case body 1, and after the handle 4 is reset, it can be conveniently pulled out for use next time, a trolley seat 2 is fixed inside the groove arranged in the left case body 1, two telescopic pull rods 3 are fixed on the top of the trolley seat 2, and the top of the two telescopic pull rods 3 is fixed with the handle 4, and a sponge cover 12 for enhancing hand comfort is fixed on the surface of the handle 4, so that the user can make the hand feel more comfortable when holding the handle 4 to drag the trolley case, a right case body 5 is arranged on one side of the left case body 1, and the left case body 1 and the right case body 5 are connected by two The metal frame 6 is connected and fixed, and a climbing auxiliary component 7 is provided on one side wall of the left box body 1. Two universal self-locking wheels 8 are installed at the bottom of the left box body 1 and the right box body 5. When using this trolley case, the telescopic rod 3 is arranged in the middle of the whole trolley case, so that when the box body is pulled, the deviation of the box body when it is pushed can be avoided. When carrying the trolley case to climb the stairs, after the telescopic rod 3 of the box body is pulled out, the box body can be tilted. When it is tilted, the climbing auxiliary component 7 contacts the stairs, and the user can drag it along the stairs, thereby facilitating the transportation of the box body and avoiding damage to the towed box body.
