Abstract
The utility model discloses a two-pulley-block driving device, which comprises a matched gear, a gear rack block, a winding wheel connected with the gear, a moving pulley block connected to the winding wheel and a connecting rod, wherein, both ends of which are respectively hinged at the moving pulley end of the moving pulley block and the edge of a drive wheel. The winding wheel is rotated by utilizing the up-down movement of the gear rack to drive the moving pulley end of the moving pulley block to move up and down. The drive wheel is driven to rotate through the connecting rod. The utility model has the advantage of great driving force by small man power. The two-pulley-block driving device can be widely used for transportation tools, such as baggage cars, transportation cars, etc.
Description
The utility model relates to a kind of sister block group actuating device.
In daily life, people are more employed to carry self-service car tool, as: baggage car, transport trolley etc. all are directly to be dragged by staff.When the thing that draws not for a long time, these car tools can also adapt to, in case pulling during weight, very effort.In existing Manpower driver, based on the strength of one's legs driving, but these actuating devices or can not be laborsaving, or complex structure, mechanism's heaviness is difficult to satisfy convenient, light and handy requirement.And some manual driving devices as are contained in shaking actuating device on disabled person's car, also are difficult to extensive utilization because of its complex structure, driving efficiency are low, especially can not be used for manpower transport's car tool.
The purpose of this utility model is to provide a kind of simple in structurely, and the driving efficiency height just can produce than large driving force with less manpower, thereby can be applicable to the actuating device on the legerity type manpower transport instrument.
Keystone configuration of the present utility model is: have in the housing and can go up, the pull bar of lower slider reaches and vertically arranged two reels of pull bar, reel is contained in the rotating shaft of housing, there is gear to cooperate in the rotating shaft with tooth bar on the pull bar, two reels are connected with an identical movable pulley group that is contained in the housing respectively by backguy, backguy one end is fixed on the housing, the other end oppositely is fixed on the reel respectively, two connecting rod one ends are hinged on the movable pulley end of movable pulley group respectively, the other end is respectively with to be installed on the housing two drive wheel edges hinged, and the hinge-point position on the drive wheel differs 180 degree, the centre of gration of the obstructed wheel of overdriving of connecting rod.
The utility model in use, the pulling catch bar, make the reel rotation, because backguy is oppositely fixing on two reels, so a reel is take-up, a reel is a unwrapping wire, and the movable pulley end of the reel pulling movable pulley group of take-up is up, and by pull bar, the pulling drive wheel rotates.Because the fixed position of pull bar on drive wheel differs 180 degree, the rotation of drive wheel is descending by the movable pulley end that another root pull bar drives movable pulley group correspondingly.When pressing down pull bar, the reel contrarotation is a reel take-up equally, another reel unwrapping wire is realized the rotation of drive wheel equally, and is identical if two connecting rods are walked around the direction of centre of gration of drive wheel, just can make one to draw the action of a pressure pull bar, drive drive wheel and rotate a circle.
The utility model adopts the movable pulley group, less external force can be changed into bigger propulsive effort, and simple in structure, and the driving efficiency height is specially adapted to the legerity type handbarrow that loading weight is loaded.
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is that scheme drawing is looked on a side drive wheel left side;
Fig. 3 is that scheme drawing is looked on the opposite side drive wheel right side.
As shown in Figure 1, the pull bar 2 that can slide up and down in the housing 1 of the present utility model reaches and vertically arranged two reels 3,3 ' of pull bar, reel is contained in the rotating shaft 4 of housing 1, there is gear 41 to cooperate in the rotating shaft 4 with tooth bar 21 on the pull bar 2, reel 3,3 ' is connected with an identical movable pulley group 6,6 ' that is contained in the housing 1 respectively by backguy 5,5 ', the movable pulley end can be connected with housing 1 by the form of feather key slide rail, the stability when moving in housing with assurance movable pulley end.Backguy 5,5 ' one end are fixed on the housing 1, the other end oppositely is fixed on respectively on the reel 3,3 ', two connecting rods 7,7 ' one ends are hinged on movable pulley group 6,6 ' movable pulley end respectively, the other end is hinged with two drive wheel 8,8 ' edges that are installed on the housing respectively, and the hinge-point position on the drive wheel differs 180 degree.The centre of gration of connecting rod 7,7 ' the obstructed wheel 8,8 ' of overdriving, draw one to press in the process of pull bar in order to make one, drive wheel rotates a circle, the direction that connecting rod 7,7 ' is walked around drive wheel 8,8 ' centre of gration is identical, shown in Fig. 2,3, because the view direction difference is so on figure, connecting rod 7,7 ' direction are opposite.
Can select pulley quantity, the arrangement of movable pulley in the utility model according to actual needs, this belongs to prior art.Provided a kind of simple movable sliding group form among Fig. 1, fixed pulley 61 or 61 ' and two movable pulley arranged side by side 62,63 or 62 ', 63 ' that is fixed on the housing 1 is promptly arranged, stay cord is walked around movable pulley, fixed pulley, movable pulley successively.The utility model in use can directly utilize drive wheel to drive, and also can steady job take turns 9 on live axle, drives other mechanical movements by blade wheel 9.
