Abstract

The utility model discloses a travelling case which comprises a case body, a case cover, zippers, a side handle, a top handle, a draw bar and universal wheels, wherein a first roller plate and a second roller plate are arranged at the back of the case body, are identical structural parts, and comprise support plates, support side plates, a plurality of rolling bearings, rollers, first fixing ends and second fixing ends; one support side plate is arranged on each of the two sides of the surface of each support plate; the rolling bearings are arranged at the upper ends of the support side plates; the rollers are arranged on the rolling bearings by small rolling shafts, and form a roller plate structure; and the roller plates are vertically fixed at the back of the case body by the first fixing ends and the second fixing ends. According to the travelling case, the roller plate structure is additionally arranged at the back of the case, so that the case can roll close to the edge of a stair step, a person is not tired during stair climbing, and the case cannot be abraded easily; and in addition, the arranged roller plate structure does not occupy internal storage of the case, so that the capacity of the case body is not affected, and the case is more convenient to use.

Description

A kind of suitcase

Technical field

The utility model relates to case and bag technical field, specifically, is a kind of suitcase with climbing stairs roller plate structure.

Background technology

Along with the development of China's economic construction and the raising day by day of living standards of the people, the item such as public affair is gone on business, training and learning, strange land exchange, labor service is contracted, gone sightseeing is more and more, therefore, increasing to the demand of suitcase.That situation with traveling bag, snakeskin bag is fewer and feweri.The railway station of China various places, airport, long-distance bus station have a large amount of crowds to flow every day, and people can see panoramic chest and knapsack.For most of passengers, rod-pulling type luggage case has been indispensable article, on market, also has now various draw-bar boxes to select for people.But present draw-bar box still has some deficiency.For example, when people haul heavier draw-bar box and run into the stair that there is no elevator, (some present multilayer houses do not have elevator, and what live upstairs can only stair climbing), only has hand to carry or luggage case could be brought up to pickaback.Present draw-bar box does not have the function of corresponding stair climbing.At present, have a kind of " Three-wheel type " luggage carrier, it alternately can move as fulcrum by three wheels and alleviate people's burden on stairway step, but removes heavier luggage case or some difficulty with it.In fact people also seldom in draw-bar box again with " Three-wheel type " luggage carrier.

Utility model content

The purpose of this utility model is to address the above problem, a kind of suitcase with climbing stairs roller plate structure is provided, at the back side of chest, is provided with roller plate, the edge that makes described chest can paste stairway step rolls, in the time of upstairs, people can be very not tired, and chest can not wear and tear easily yet.

For achieving the above object, the utility model has been taked following technical scheme.

A suitcase, contains casing, case lid, slide fastener, side handle, top handle, pull bar and universal wheel, it is characterized in that, is provided with the first roller plate and second tin roller plate at the back side of described casing, described the first roller plate and second tin roller plate are identical structural member, contain gripper shoe, support side plate, rolling bearing, cylinder, the first stiff end and the second stiff end: the both sides on described gripper shoe face respectively arrange a support side plate, in the upper end of described support side plate, some rolling bearings are set, on rolling bearing in support side plate corresponding to both sides, by little roller bearing, cylinder is set, described cylinder forms roller plate structure, by described roller plate---comprise that the first roller plate and second tin roller plate are vertically fixed on the back side of described casing by the first stiff end and the second stiff end.

Further, described the second stiff end being to 90 ° curves inwardly and is fixed on the bottom surface of described casing.

Further, described the first roller plate and second tin roller plate are arranged on the position, middle and lower part of described box back surface, and roller plate extends to the bottom of described box back surface.

Further, the two ends of described the first roller plate and second tin roller plate are the gradient or arcuate structure.

The good effect of a kind of suitcase of the utility model is: at the back side of chest, increased roller plate structure, the edge that makes described chest can paste stairway step rolls, and in the time of upstairs, people can be very not tired, and chest can not wear and tear easily yet.In addition, because roller plate is arranged on the outside at the chest back side, do not take the internal memory of chest, thus the capacity of casing do not affected, as long as chest backboard is suitably reinforced.

The specific embodiment

Below in conjunction with accompanying drawing, provide the specific embodiment of a kind of suitcase of the utility model, still, enforcement of the present utility model is not limited to following embodiment.

Referring to Fig. 1.A suitcase, contains casing 1, case lid 2, slide fastener 3, side handle 4, top handle 5, pull bar 6 and universal wheel 9, and said structure part can adopt the structural member of existing chest.The utility model will be done: the first roller plate 7 and second tin roller plate 8 are set at the back side of described casing 1, make casing 1 back side have slidably structure.

Described the first roller plate 7 and second tin roller plate 8 are identical structural member, and they all contain gripper shoe 10, support side plate 11, rolling bearing 12, cylinder 13, the first stiff end 14 and the second stiff end 15(referring to Fig. 2).Described gripper shoe 10, support side plate 11, cylinder 13, the first stiff end 14 and the second stiff end 15 should adopt metal sheeting design part.Each arranges (welding) support side plate 11 both sides in 10 of described gripper shoes, in the upper end of described support side plate 11, some through holes are set, in described through hole, set rolling bearing 12, should make the skin of rolling bearing 12 corresponding with the upper end of described support side plate 11 fixing (spot welding), then on the rolling bearing 12 in support side plate 11 corresponding to both sides by little roller bearing setting (socket) cylinder 13, the limit of socket back roll 13 should exceed the upper end of support side plate 11, and described cylinder 13 can first be contacted with extraneous.The cylinder 13 consisting of some rolling bearings 12 forms roller plate structure.
