Abstract
The utility model discloses an obstacle-crossing type draw-bar box, which is provided with crawler transmission mechanisms on the back of the box body, so that the box body can be drawn on the flat ground, and can go up and down stairs. An upper driving wheel is connected with an upper end head of a jointing seat through a wheel shaft; a lower driving wheel is connected with a lower end head of the jointing seat through the wheel shaft; a supporting strip is arranged between the upper driving wheel and the lower driving wheel and connected with the jointing seat through a plurality of pins; a driving belt is sleeved on the upper driving wheel, the supporting strip and the lower driving wheel; and the upper driving wheel, the supporting strip, the lower driving wheel, the driving belt and the jointing seat form one crawler transmission mechanism. A plurality of crawler transmission mechanisms are connected to the back of the box body through the jointing seat. When going upstairs, a drawbar can be used for drawing the box body to go forward; when the crawler transmission mechanisms on the back of the box body are in contact with the steps, the box body can move upwards along the steps through the operation of the driving belt. When going downstairs, the drawbar can be used for pushing the box body to go forward, and the box body can move down along the steps through the operation of the driving belt.
Description
Technical field
The utility model relates to a kind of draw-bar box, especially the crawler belt transmission mechanism can be set through the back side at casing, thereby casing can be slided and obstacle crossing type draw-bar box that can stair activity on the level land.
Background technology
Therefore at present, known draw-bar box is not provided with the auxiliary drive gear that stair activity is used, and can only on the level land, slide and is not easy to stair activity.
Summary of the invention
In order to overcome that existing draw-bar box can only slide on the level land and the deficiency that is not easy to stair activity; The utility model provides a kind of obstacle crossing type draw-bar box; This obstacle crossing type draw-bar box can be provided with the crawler belt transmission mechanism through the back side at casing, thereby casing can be slided and can easily stair activity on the level land.
The utility model solves the technical scheme that its technical problem adopted: the utility model comprises pull bar, casing, connection seat, driving-belt, roller, bearing pin, support strip, goes up drive, lower driving wheel and wheel shaft.Connecting seat is rectangular box body structure; In connecting seat, be provided with drive, support strip and lower driving wheel; Last drive is connected the upper end that connects seat through wheel shaft; Lower driving wheel is connected the lower end that connects seat through wheel shaft, and support strip is arranged between drive and the lower driving wheel and through some bearing pins and is connected with the connection seat, and driving-belt is a loop configuration; Driving-belt is sleeved on drive, support strip and the lower driving wheel, and last drive, support strip, lower driving wheel, driving-belt and connection seat are formed the crawler belt transmission mechanism jointly.Several crawler belt transmission mechanisms are through connecting the back side that seat is connected casing, and the traffic direction of driving-belt is consistent with the traffic direction of bottom half roller in the crawler belt transmission mechanism.When on the level land, using, through pull bar pulling casing, casing slides on the ground through roller and moves ahead.When going upstairs, move ahead through pull bar pulling casing, when the crawler belt transmission mechanism of box back surface contacted with marking time of stair, casing can move up along marking time of stair through the operation of driving-belt.When going downstairs, promote casing through pull bar and move ahead, when the roller of bottom half rolled out the platform of stair, the crawler belt transmission mechanism of box back surface can contact with marking time of stair, and casing just can move down along marking time of stair through the operation of driving-belt.
The beneficial effect of the utility model is, the crawler belt transmission mechanism can be set through the back side at casing, thereby casing can be slided and can easily stair activity on the level land.
