Utility model content
The utility model is mainly for the problems referred to above, the portable ruler of provide a kind of length that can extend ruler, reduce to take up room, be easy to carry, can be connected with rubber, avoiding rubber to lose falling.
The purpose of this utility model is mainly achieved by following proposal: a kind of portable ruler, comprise and be with graduated chi plate, also comprise mainboard, one end of mainboard is provided with articulated joint, and described chi plate comprises first chi and second chi, and first chi is positioned at the upper end of mainboard, second chi is positioned at the lower end of mainboard, first chi and second chi and articulated joint are hinged, and mainboard middle part is provided with slip draw-in groove, is provided with the rubber slide block being slidably connected with the draw-in groove that slides in slip draw-in groove.Chi plate comprises first chi and second chi, and first chi is positioned at the upper end of mainboard, and second chi is positioned at the lower end of mainboard, and first chi and second chi are hinged by articulated joint, and the scale on the scale on first chi and second chi is continuous.In the time that the length of first chi cannot meet measurement demand, first chi and second chi to be rotated around articulated joint, rotation is to first chi and second chi to being connected into whole piece ruler, and now, first chi is located on the same line with second chi and is vertical with mainboard.Mainboard middle part arranges slip draw-in groove, and rubber slide block is set in slip draw-in groove, and rubber slide block can slide along slip draw-in groove, in the time that rubber slide block does not need to use, rubber slide block is slid into mainboard middle part, can prevent that rubber from losing or leak band while carrying.In the time that rubber slide block need to use, rubber slide block is slid into mainboard one end away from articulated joint, just erasable person's handwriting.First chi and second chi can splice and extend measures length, and is convenient to folding carrying, and reduces to take up room.
As preferably, described slip draw-in groove is T-slot, and the section of rubber slide block is " protruding " font, rubber slide block and slip draw-in groove matched in clearance.Slip draw-in groove is T-slot, the section of rubber slide block is " protruding " font, and rubber slide block and slip draw-in groove matched in clearance guarantee that rubber slide block can slide in slip draw-in groove, and slip draw-in groove can carry out rubber slide block spacingly, prevent that rubber slide block from coming off in slip draw-in groove.
As preferably, first described chi and second chi are all L-shaped.First chi and second chi are all L-shaped, when rotation docking, can be spliced into a complete straight line, avoid occurring error.
As preferably, the bottom land of the slip draw-in groove on described mainboard is provided with several for drawing the through hole of figure.The bottom land of the slip draw-in groove on mainboard is provided with several for drawing the through hole of figure, and through hole can be made into the conventional geometries such as circle, ellipse, square, rectangle, is convenient to children and draws figure.
As preferably, described mainboard is connected with articulated joint one.Mainboard is connected with articulated joint one, avoids articulated joint and mainboard fracture, strengthens structural strength, avoids articulated joint to rock and occurs measure error.
Therefore, portable ruler of the present utility model possesses following advantage: 1, chi plate comprises first chi and second chi, and first chi is positioned at the upper end of mainboard, and second chi is positioned at the lower end of mainboard, first chi and second chi are hinged by articulated joint, and the scale on the scale on first chi and second chi is continuous.In the time that the length of first chi cannot meet measurement demand, first chi and second chi are rotated around articulated joint, rotation to first chi and second chi to being connected into whole piece ruler, now, first chi is located on the same line with second chi and is vertical with mainboard, mainboard middle part arranges slip draw-in groove, rubber slide block is set in slip draw-in groove, rubber slide block can slide along slip draw-in groove, in the time that rubber slide block does not need to use, rubber slide block is slid into mainboard middle part, while carrying, can prevent that rubber from losing or leak band, in the time that rubber slide block need to use, rubber slide block is slid into mainboard one end away from articulated joint, just erasable person's handwriting.First chi and second chi can splice and extend measures length, and is convenient to folding carrying, and reduces to take up room; 2, slip draw-in groove is T-slot, the section of rubber slide block is " protruding " font, and rubber slide block and slip draw-in groove matched in clearance guarantee that rubber slide block can slide in slip draw-in groove, and slip draw-in groove can carry out rubber slide block spacingly, prevent that rubber slide block from coming off in slip draw-in groove; 3, first chi and second chi are all L-shaped, when rotation docking, can be spliced into a complete straight line, avoid occurring error.
