Description
Technical field
The utility model relates to a kind of rod-pulling type suitcase.
Background technology
In the prior art, the bottom of rod-pulling type suitcase is provided with trailing wheel, affects pull bar that suitcase is walked on the level land.But when the user need be with suitcase along travelling up or down a flight of stairs, because trailing wheel suffered resistance on ladder is bigger, and suitcase was subjected to serious collision on ladder, and the user often need mention casing, brings inconvenience to the user.
Summary of the invention
The utility model purpose provides a kind of rod-pulling type suitcase, and the user can easily tractive walking on ladder.
For achieving the above object, the technical solution adopted in the utility model is: a kind of rod-pulling type suitcase, comprise casing, rotationally be arranged at the bottom of described casing at least one pair of trailing wheel, be arranged on the pull bar of the front portion of described casing, the bottom of described casing also is provided with at least one pair of front-wheel, described trailing wheel is pivotally connected on the casing by rear wheel support, described front-wheel is pivotally connected on the casing by front-wheel support, and described front-wheel and trailing wheel upper edge outer circumference surface are surrounded with crawler belt.
Because the technique scheme utilization, the utility model compared with prior art has following advantage: front-wheel is set up in the front portion at casing, and crawler belt is around the outer circumference surface setting of trailing wheel and front-wheel, when on ladder, walking, direct stayed pole, crawler belt just can slide on ladder, and is laborsaving and convenient.
Description of drawings
Accompanying drawing 1 is a main cutaway view of the present utility model;
Wherein: 1, casing; 2, pull bar; 3, crawler belt; 4, front-wheel; 5, front-wheel support; 6, trailing wheel; 7, rear wheel support; 8, front apron; 9, backboard;
The specific embodiment
Referring to accompanying drawing 1, a kind of rod-pulling type suitcase, comprise casing 1, rotationally be arranged at the bottom of described casing 1 at least one pair of trailing wheel 6, be arranged on the pull bar 2 of the front portion of described casing 1, the bottom of described casing 1 also is provided with at least one pair of front-wheel 4, described trailing wheel 6 is pivotally connected on the casing 1 by rear wheel support 7, described front-wheel 4 is pivotally connected on the casing 1 by front-wheel support 5, and described front-wheel 4 is surrounded with crawler belt 3 with trailing wheel 6 upper edge outer circumference surfaces.Crawler belt 3 is around the trailing wheel 6 outer circumference surface setting with front-wheel 4, when on ladder, walking, and direct stayed pole 2, crawler belt 3 just can slide on ladder, and is laborsaving and convenient.And in order to adapt to the inclination characteristics of ladder, the diameter of described front-wheel 4 is less than the diameter of trailing wheel 6, and the bottom of front-wheel 4 is higher than the bottom of trailing wheel 6.Crawler belt 3 forms domatic between front-wheel 4 and trailing wheel 6, can make things convenient for moving of crawler belt 3.
Referring to accompanying drawing 1, come off on trailing wheel 6 for preventing crawler belt 3, have the backboard 9 that is positioned at trailing wheel 6 both sides on the described rear wheel support 7, described backboard 9 retainings are in the both sides of crawler belt 3.And, having the front apron 8 that is positioned at front-wheel 4 both sides on the described front-wheel support 5 for prevent that crawler belt 3 from coming off on front-wheel 4, described front apron 8 retainings are in the both sides of crawler belt 3.By the barrier effect of backboard 9 with front apron 8, crawler belt 3 moves between baffle plate, the trouble in the time of can avoiding using.
And crawler belt 3 also can be avoided being displaced sideways by alternate manner, and for example: the both sides of described trailing wheel 6 have the radially back back-up ring of projection, and described back back-up ring retaining is in the both sides of crawler belt 3, and back back-up ring can replace backboard 9 to use.The both sides of described front-wheel 4 have the radially preceding back-up ring of projection, and described preceding back-up ring retaining is in the both sides of crawler belt 3, and preceding back-up ring also can replace front apron 8 to use.
