Abstract
The utility model relates to an infinitely-extending straight ruler which comprises a ruler plate. A sliding groove parallel to the ruler edge with scale lines is formed in the ruler plate, and a guiding block capable of sliding is connected to the sliding groove in a clamped mode. The guiding block of the infinitely-extending straight ruler enables the ruler plate to move in an attached, parallel and smoothly extending mode, and an infinitely-extending straight line can be drawn through the short straight ruler. The infinitely-extending straight ruler has the advantages of being small in size, saving the manufacturing cost, being used for replacing a long ruler to be used and being practical.
Description
Technical field
The utility model relates to a kind of ruler, especially relates to a kind ofly can infinitely extending continuously the ruler of picture straight line.
Background technology
Existing ruler exists the limitation of length, and draw one needs mobile ruler connect the continuation setting-out than ruler long straight line also, and owing to having moved ruler, the extended line drawn is difficult to connect into straight line with former straight line, and drawing quality is affected.
Summary of the invention
The purpose of this utility model is for existing deficiency, provides a kind of and can infinitely extend continuously the ruler that draws straight line.
The utility model solves the technical scheme that its technical problem adopts: a kind of unlimited extension ruler, comprise the chi plate, and described chi plate is provided with a chute paralleled with the chi limit of graduation mark, and the chute clamping is guiding block slidably.
Described chi plate two ends are provided with the barrier plate to downward-extension, make the chi limit of clamping guiding block form " recessed " shape, and guiding block is limited in " recessed " shape.
The utility model is provided with a guiding block on the chi plate, and guiding block makes the chi plate by developing the capable movement of postponing, and makes short and small ruler draw the straight line of unlimited prolongation.The utility model has the advantages that volume is little, manufacturing cost is economized, and substitutes long ruler and uses, very practical.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and the embodiments, the utility model is described in further detail.
The specific embodiment
As shown in the figure, a kind of unlimited extension ruler, comprise chi plate 1, Yi Bian chi plate 1 indicates graduation mark 11, the another side of chi plate 1 is provided with the chute 12 paralleled with the chi limit that indicates graduation mark, and chute 12 clampings are guiding block 2 slidably.Be provided with the barrier plate 13 to downward-extension at the two ends of chi plate 1, make the chi limit of clamping guiding block 2 form " recessed " shape, guiding block 2 is limited in " recessed " shape.
During operation, after painting article one straight line, pin guiding block 2, chi plate 1, by pasting the parallel movement of postponing of guiding block 2, then is drawn to the straight line extended continuously, until reach Len req.
