Abstract
The invention discloses a lengthening ruler. The lengthening ruler comprises ruler plates, 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 length directions of the first middle ruler and the second middle ruler are respectively provided with an upper neck and a lower neck; one end of the length direction of the first edge ruler is provided with an upper neck, and a lower neck is formed in one end of the length direction of the first edge ruler; in the process of installation and connection, the upper neck of the first middle ruler is connected with the lower neck of the second middle ruler in a matched mode through a spindle; the lower neck of the first middle ruler is connected with the upper end of the first edge ruler in a matched mode through the spindle; and the upper neck of the second middle ruler is connected with the lower neck of the second edge ruler in a matched mode through the spindle. The lengthening ruler enables the two sides ruler plates to be convenient to rotatably accommodate, fold, and bring along the spindle when the lengthening ruler is carrying, and the occupied space is small; in practical use, the lengthening ruler enables the two sides ruler plates to rotate outside along the spindle, lengthens using length of the ruler, and is not subject to length restriction of the ruler when drawing pictures.
Description
Technical field
The present invention relates to a kind of ruler, relate in particular to a kind of ruler that can lengthen, belong 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 inconvenience aspect preservation actual.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of ruler that can lengthen, and avoided the actual deficiency of using and carrying the preservation aspect.
Technical solution of the present invention is achieved in that a kind of lengthening chi, comprises the chi plate, and described chi plate comprises chi in chi in first, second, first side chi, Second Edge chi; In described first in chi and second two ends of chi length direction be respectively equipped with draw-in groove, lower bayonet slot; One end of described first side chi length direction is provided with draw-in groove; One end of described Second Edge chi length direction is provided with lower bayonet slot; When described installation connects, in first in the upper draw-in groove and second of chi the lower bayonet slot of chi be connected by rotating shaft; In described first the upper draw-in groove of the lower bayonet slot of chi and first side chi by rotating shaft be connected; In described second, the lower bayonet slot of the upper draw-in groove of chi and Second Edge chi is connected by rotating shaft.
Preferably, chi in chi, second in described first, first side chi, Second Edge chi two ends are provided with chamfering.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Lengthening chi of the present invention connects each independent chi plate by rotating shaft.When carrying with both sides chi plate along rotating shaft rotation take in, fold, easy to carry, take up room little; When reality is used, both sides chi plate is spun out along rotating shaft, lengthen the use length of ruler, make when drawing, be not subjected to as much as possible the ruler length restriction.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the three-dimensional structure diagram of lengthening chi of the present invention;
Accompanying drawing 2 is the deployed condition structure chart of lengthening chi of the present invention;
Accompanying drawing 3 is lengthening chi deployed condition cutaway view of the present invention;
Wherein: 1, chi in second; 2, chi in first; 3, Second Edge chi; 4, first side chi; 5, upper draw-in groove; 6, lower bayonet slot; 7, rotating shaft; 8, chamfering.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1,2,3 is a kind of lengthening chi of the present invention, comprises the chi plate, and described chi plate comprises in first chi 1, first side chi 4, Second Edge chi 3 in chi 2, second; In described first in 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 described first side chi 4 length directions is provided with draw-in groove 5; One end of the long 3 degree directions of described Second Edge chi is provided with lower bayonet slot 6; When described installation connects, in first in the upper draw-in groove 5 and second of chi 2 lower bayonet slot 6 of chi 1 be connected by rotating shaft 7; In described first the upper draw-in groove 5 of the lower bayonet slot 6 of chi 2 and first side chi 4 by rotating shaft 7 be connected; In described second, the upper draw-in groove 5 of chi 1 is connected by rotating shaft 7 with the lower bayonet slot 6 of Second Edge chi 3; Chi 1 in chi 2, second in described first, first side chi 4, Second Edge chi 1 two ends are provided with chamfering 8.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Lengthening chi of the present invention connects each independent chi plate by rotating shaft.When carrying with both sides chi plate along rotating shaft rotation take in, fold, easy to carry, take up room little; When reality is used, both sides chi plate is spun out along rotating shaft, lengthen the use length of ruler, make when drawing, be not subjected to as much as possible the ruler length restriction.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and be implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
