Abstract
The utility model relates to a lengthening ruler, comprising a ruler plate, wherein the ruler plate comprises a first middle ruler, a second middle ruler, a first edge ruler and a second edge ruler; two ends of the first middle ruler and the second middle ruler in a length direction are respectively provided with an upper clamping groove and a lower clamping groove; one end of the first edge ruler in the length direction is provided with an upper clamping groove; one end of the second edge ruler in the length direction is provided with a lower clamping groove; when the rulers are mounted and connected, the upper clamping groove of the first middle ruler and the lower clamping groove of the second middle ruler are matched and connected through a rotating shaft; the lower clamping groove of the first middle ruler and the upper clamping groove of the first edge ruler are matched and connected through the rotating shaft; and the upper clamping groove of the second middle ruler and the lower clamping groove of the second edge ruler are matched and connected through the rotating shaft. With the adoption of the lengthening ruler disclosed by the utility model, when the lengthening ruler is carried, two edge ruler plates are rotated along the rotating shaft to be stored and folded so that the lengthening ruler is convenient to carry and the occupied space is small; when the lengthening ruler is actually used, the two edge ruler plates are rotated out along the rotating shaft, so as to lengthen the use length of the ruler; and when the lengthening ruler is used for drawing, the drawing is not limited by the length of the ruler.
Description
Technical field
The utility model relates to a kind of ruler, relates in particular to a kind of ruler that can extend, and belongs to stationery study article technical field.
Background technology
At present, the ruler that generally uses can be because the length of ruler own be restricted when measuring or draw, if excessive increase ruler size inevitably can cause ruler to use and carry the inconvenience aspect the preservation actual.
The utility model content
The utility model purpose is for the deficiency that overcomes prior art a kind of ruler that can extend to be provided, and has avoided the actual deficiency of using and carrying the preservation aspect.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of lengthening chi, comprise the chi plate, and said chi plate comprises chi in the chi in first, second, the first limit chi, the second limit chi; In said first in the chi and second two ends of chi length direction be respectively equipped with draw-in groove, lower bayonet slot; One end of the said first limit chi length direction is provided with draw-in groove; One end of the said second limit chi length direction is provided with lower bayonet slot; When said installation connects, in first in the last draw-in groove and second of chi the lower bayonet slot of chi be connected through rotating shaft; In said first the last draw-in groove of the lower bayonet slot of chi and the first limit chi through rotating shaft be connected; The lower bayonet slot of the last draw-in groove of chi and the second limit chi is connected through rotating shaft in said second.
Preferably, in said first in the chi, second chi, the first limit chi, chi two ends, second limit be provided with chamfering.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The lengthening chi of the utility model scheme connects each independent chi plate through rotating shaft.When carrying with both sides chi plate along rotating shaft rotation take in, fold, easy to carry, it is little to take up room; When reality is used, both sides chi plate is spun out along rotating shaft, the use length of lengthening ruler makes when drawing, and does not receive the ruler length restriction as much as possible.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the three-dimensional structure diagram of the lengthening chi of the utility model;
Accompanying drawing 2 is the deployed condition structure chart of the lengthening chi of the utility model;
Accompanying drawing 3 is the lengthening chi deployed condition cutaway view of the utility model;
Wherein: 1, chi in second; 2, chi in first; 3, the second limit chi; 4, the first limit chi; 5, go up draw-in groove; 6, lower bayonet slot; 7, rotating shaft; 8, chamfering.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Accompanying drawing 1,2,3 is the described a kind of lengthening chi of the utility model, comprises the chi plate, and said chi plate comprises in first in the chi 2, second chi 1, the first limit chi 4, the second limit chi 3; In said first in the chi 2 and second two ends of chi 1 length direction be respectively equipped with draw-in groove 5, lower bayonet slot 6; One end of the said first limit chi, 4 length directions is provided with draw-in groove 5; One end of the said second limit chi, 3 length directions is provided with lower bayonet slot 6; When said installation connects, in first in the last draw-in groove 5 and second of chi 2 lower bayonet slot 6 of chi 1 be connected through rotating shaft 7; The last draw-in groove 5 of the lower bayonet slot 6 of chi 2 and the first limit chi 4 is connected through rotating shaft 7 in said first; The lower bayonet slot 6 of the last draw-in groove 5 of chi 1 and the second limit chi 3 is connected through rotating shaft 7 in said second; Chi 1 in the chi 2, second in said first, the first limit chi 4, the second limit chi, 1 two ends are provided with chamfering 8.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The lengthening chi of the utility model scheme connects each independent chi plate through rotating shaft.When carrying with both sides chi plate along rotating shaft rotation take in, fold, easy to carry, it is little to take up room; When reality is used, both sides chi plate is spun out along rotating shaft, the use length of lengthening ruler makes when drawing, and does not receive the ruler length restriction as much as possible.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
