Abstract
The utility model relates to an up-down blackboard. The existing blackboards are easy to swing, deflect and jam when the blackboards move up and down. The utility model has the structure that a vertical guide rail is respectively arranged at both sides of two pieces of blackboards which are not in the same plane, the left and the right of the guide rail are provided with flanges, the four corners of each blackboard face are respectively and fixedly provided with a guide wheel combination composed of two guide wheels, and the left and the right ends of the cross beam above the blackboard face are respectively provided with a left pulley and a right pulley. The left side of the blackboard is provided with a left rope which is arranged on the left pulley, both ends of the left rope are respectively and fixedly connected with two pieces of blackboard faces, and the right side of the blackboard has the same structure with the left side. The two guide wheels of the guide wheel combination are separately contacted with the left and the right flanges of the corresponding guide rails. The utility model has the advantage that the utility model is not easy to swing, deflect and jam when moving up and down.
Description
But the utility model is a kind of blackboard of two boards face vertical lift.
Granted publication number has been announced a kind of " multifunctional lifting blackboard " for the Chinese patent literature of CN2163077Y, be characterized on the reverse side of blackboard or easel, being fixed with cylindricality guide rail perpendicular to horizontal plane, correspondingly, on the easel and the blackboard reverse side be fixed with directive wheel, the balanced controls that blackboard need be made up of pulley, counterweight rope and mass.The shortcoming of its used suspension lifting device be blackboard in lifting process, easily produce rock, deflection and being stuck.
The purpose of this utility model provide in a kind of lifting process the plate face can not produce rock, deflection and jammed blackboard movable up and down.
Structure of the present utility model is: two adjacent to each other but not the blackboard panel in same plane set up perpendicular to horizontal plane, the place ahead of every blackboard panel or both sides, rear are provided with a vertical guide rail, about every guide rail itself flange is arranged, be fastened with a guide wheel combination of forming by two guide wheels on four angles of every blackboard panel, the rotating shaft of two guide wheels is in same horizontal plane and is parallel to each other in the guide wheel combination, the blackboard panel top is provided with the entablature of a level, the left end of entablature is provided with a left chain wheel and right-hand member is provided with a right pulley, there is a left side rope that is held on the left chain wheel on the left side of blackboard, the two ends of left side rope are fastening with two blackboard panels respectively, there is a right side rope that is held on the right pulley on the right of blackboard, the two ends of right rope are also fastening with two blackboard panels respectively, two guide wheels in each guide wheel combination respectively with respective track on a left side, right flange contact.
When the utility model uses, movingly make a blackboard panel to rising or when descending when the end user touches with have gentle hands because the affecting of left side rope and right rope, another piece blackboard panel will be synchronously to descending or to rising, thereby do not hide mutually.Not only because the gravitational equilibrium of two blackboard panels, thereby lifting is laborsaving, and every blackboard panel all has two guide wheels for four jiaos, so the plate face moves steadily unobstructed in the lifting process.
Compare with prior art, advantage of the present utility model just be in the lifting process plate face can not produce rock, deflection and being stuck.
