Description
Technical field
The utility model relates to a kind of articles for daily use, especially relates to a kind of hand pulling type travel suitcase stair-climbing mechanism.
Background technology
People when being with bigger article if desired, usually can using and pull suitcase when trip.Pull suitcase and saved many muscle power on the road, but when stair activity, just must mention suitcase and could continue to move ahead for people, if the article in the suitcase are bigger, just need to consume a large amount of muscle power, run into user's strength condition of limited, even just because can't move ahead.The defective of comparatively giving prominence to before therefore traditional hand pulling type suitcase still has in this respect.Defective when going upstairs in order to solve this hand pulling type suitcase, people had once thought deeply the whole bag of tricks.As application number is that 200710013227.X discloses a kind of crawler type suitcase, the inner bottom surface of casing is double-deck bottom surface, two ends are provided with support in the space between two bottom surfaces, support is provided with pulley, the tank floor two ends are provided with two openings, and crawler belt passes opening and walks around pulley and be located on the interior outer bottom of casing.In the time of upstairs, suitcase is gone upstairs by the slip of pulling force and crawler belt.This design needs crawler belt longer, and is relatively heavier, and in use, and so user's pulling chest of need possessing a person is can be very tired.Application number is that 200320100094.7 patent of invention discloses a kind of suitcase, and its casing is provided with pedestal, and this pedestal is fixed on a side of casing, and the outer rim of this pedestal is provided with groove, is movably set with pulley on this pedestal, has set up crawler belt on this pulley.This design is owing to the installation of crawler belt is fixed, so when not needing to go upstairs, it is bigger to rub in the pulling chest process, relatively effort.And owing to its angle is fixed, so the incompatible needs of the stair of multiple differing heights up and down.
During again owing to stair activity, the general designed stair-climbing mechanism of suitcase all can cause chest that certain jolting arranged, so the shock resistance to this mechanism has proposed higher requirement,, all this or similar means are not carried out feasible improvement having retrieved relevant patent.
Summary of the invention
The utility model mainly is that to solve the shock resistance of stair-climbing mechanism of the existing suitcase that pulls stair activity of existing in prior technology not enough, problem also attractive in appearance inadequately, disclose a kind of simple in structure, the stair-climbing mechanism of good looking appearance, suitcase easy to assembly.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of stair-climbing mechanism of suitcase; comprise the rolling mechanism of being located at the casing rear side; the back side lower part that it is characterized in that described casing is provided with several grooves; and there is a trough-shaped housing adaptive with it respectively; rolling mechanism is located in the trough-shaped housing; described rolling mechanism comprises wheel box and some trundles or crawler belt; be provided with the protection rib around the box mouth of wheel box, the edge of trundle or crawler belt exceeds the box mouth of wheel box.The groove with on the casing of trough-shaped housing matches, feasible integral body is more attractive in appearance, rolling mechanism is located in this trough-shaped housing, and the suffered concussion of this rolling mechanism passes to trough-shaped housing earlier, makes casing and be loaded on the concussion that the article in the casing are subjected to and greatly reduce.The length of trough-shaped housing and is provided with trundle or crawler belt on this length in 15-35 centimetre scope, make it to reach certain angle pulling to support when going upstairs, and can make tourelle and two step smooth transitions up and down.The width of protection rib is slightly larger than the thickness of cell wall, and trough-shaped housing is played a protective role, and also trundle or crawler belt, Athey wheel is played a protective role simultaneously.
As preferably, the turning cylinder of described trundle is located on two lateral box walls of wheel box, and the edge of trundle exceeds 0.2-2 centimetre in wheel box mouth.The wheel box becomes the direct support section of trundle, and the impact that is subjected to when making wheel work is just passed on the trough-shaped housing by the transition of wheel box, and trough-shaped housing has also been played protective effect.Simultaneously, this design has also made things convenient for the assembling of this mechanism.
As preferably, the turning cylinder of described Athey wheel is located on the both sides cell wall of wheel box, and the Athey wheel outside is provided with crawler belt, and the outside of crawler belt exceeds 0.2-2 centimetre in wheel box mouth.The fluctuation that the advantage of crawler belt is further to reduce to pull casing when going upstairs has realized that real stepless difference goes upstairs.
As preferably, described trundle single or plurality of rows in each takes turns box is staggered.Being staggered trundle can be so that tourelle contacts with step when moving upward, and it is less to fluctuate, and makes when using more stable.
As preferably, the groove of side lower part has two behind the described casing, is located at two inferior horns at casing rear portion respectively, and the edge of trough-shaped housing has alar part, and alar part is respectively with two jiaos of parcels.Alar part can form a triangular taper, matches with two jiaos of casing, has reached the protective effect to casing.
As preferably, described protection rib adopts plastic cement, metal or elastomeric material, and the width of protection rib is greater than the thickness of wheel box wall, and about wheel box wall symmetry.And the protection rib also can use other current material.
As preferably, described take turns box oral area two sides be shaped as straight shape, beveled or circular arc.
The beneficial effect that brings of the present utility model is, this installed this mechanism pull suitcase or other handcraft can spur in the process of going upstairs stably, and easy to use, profile is succinctly attractive in appearance.
