When the cross-country trolley case is in use, the left supporting arm and the right supporting arm are turned outwards by 90 degrees, and after the lock rods and the lock holes lock the supporting arms, the box is enabled to walk up and down the stairs or get through the waterlogged road surfaces through the auxiliary pulleys; when the left supporting arm, the right supporting arm, the left auxiliary pulley and the right auxiliary pulley are stored in a groove in a backplate of the box, the box can slide through the main pulleys.
Description
Technical field
The present invention relates to a kind of draw-bar box, especially by arranging one group of telescopic auxiliary pulley on casing, thus helping casing stair activity and the cross-country trolley case by ponding road surface.
Background technology
At present, known draw-bar box due to the diameter of its pulley less, therefore neither facilitating going upstairs and going downstairs again not by the road surface of ponding.
Summary of the invention
In order to overcome existing draw-bar box neither facilitating going upstairs and going downstairs again not by the deficiency on ponding road surface, the invention provides a kind of cross-country trolley case, this cross-country trolley case by arranging one group of telescopic auxiliary pulley on casing, thus helps casing stair activity and the road surface by ponding.
The technical solution adopted for the present invention to solve the technical problems is: the present invention includes pull bar, casing, auxiliary pulley, head pulley, dynamic rotating shaft, control lever, supporting arm, groove, locking bar, determine rotating shaft, lockhole, waist hole and spring.Supporting arm is column construction, longitudinal central axis line along supporting arm offers centre bore, the post jamb of supporting arm offers the waist hole be communicated with centre bore, and upper lower shaft hole is opened in the two ends up and down of supporting arm respectively, and upper lower shaft hole is parallel to each other and simultaneously perpendicular to the longitudinal central axis line of supporting arm.Determine the back-end location that rotating shaft is connected to bottom half, the left and right spindle nose determining rotating shaft is connected to left and right head pulley, left and right supporting arm is connected with the left and right axle journal determining rotating shaft respectively by lower shaft hole, on the left and right axle journal determining rotating shaft, circumferentially face all offers several lockholes, and the position of lockhole is corresponding with the centre bore of supporting arm.In the centre bore of left and right supporting arm, be sequentially set with locking bar and spring all from bottom to top, the waist hole that the termination, left and right of control lever is each passed through on the supporting arm of left and right is connected with the locking bar in supporting arm.The left and right axle journal of dynamic rotating shaft is connected with the upper shaft hole of left and right supporting arm respectively, and left and right auxiliary pulley is connected on the left and right spindle nose of dynamic rotating shaft.The backboard of casing is provided with the groove matched with left and right supporting arm, dynamic rotating shaft, control lever and left and right auxiliary pulley.In using, left and right locking bar is driven to move backward along the centre bore of supporting arm by control lever, releasing locking bar and lockhole are to the locking of left and right supporting arm, again left and right supporting arm, dynamic rotating shaft, control lever and left and right auxiliary pulley are outwards turned over and turn 90 degrees, after left and right supporting arm locks by locking bar and lockhole under the action of the spring, pull casing by pull bar again, now casing is namely by auxiliary pulley stair activity or the road surface by ponding.When smooth ground is slided, locking bar and lockhole is removed to the locking of left and right supporting arm by control lever, by left and right supporting arm reverse flip 90 degree, left and right supporting arm, dynamic rotating shaft, control lever and left and right auxiliary pulley is made to be collected in the groove on casing backboard, pull casing by pull bar again, now namely casing slides by head pulley.
The invention has the beneficial effects as follows, by arranging one group of telescopic auxiliary pulley on casing, thus helping casing stair activity and the road surface by ponding.
