Abstract
The utility model relates to a ruler, particularly to a telescopic ruler. The telescopic ruler comprises a main ruler and an auxiliary ruler which are parallel with each other, wherein a limited post is arranged at one end of the main ruler and in the position close to the end thereof; a separation blade is fixedly arranged on the top end of the limited post; a strip-shaped hole is formed on the auxiliary ruler; the limited post of the main ruler is placed in the strip-shaped hole of the auxiliary ruler; and the auxiliary ruler is in sliding fit with the main ruler through the limited post. The utility model overcomes the use limitation caused by the length restriction of the prior ordinary ruler, can be conveniently carried and placed, and has the advantages of simple and reasonable structure, low cost, long service life and little possibility of deformation.
Description
Technical field
The utility model relates to a kind of ruler, particularly a kind of telescopic ruler.
Background technology
The normally used ruler of people mostly is single chi at present, in use, often because of the ruler length restriction, causes and uses limitation.As doing ruler long, certainly will give again and carry and placement is made troubles.Though some telescopic rulers designs in some technical literatures, also occurred, but still existed shortcomings such as structure relative complex, cost height, fragile, distortion.
The utility model content
Technical problem to be solved in the utility model provides a kind of telescopic ruler to overcome the deficiencies in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: telescopic ruler, form with secondary chi 2 by the main scale 1 that is parallel to each other, wherein main scale 1 one end proximal ends are provided with limited post 3, limited post 3 tops are installed with catch 4, offer bar hole 5 on the secondary chi 2, limited post 3 on the main scale 1 places in the bar hole 5 of secondary chi 2, and secondary chi 2 is slidingly matched by limited post 3 and main scale 1.
Described main scale 1 also offers the groove 6 that secondary chi bottom can be embedded with respect to secondary chi 2 shapes.
The scale of described main scale 1 is terminal corresponding with the scale top of secondary chi 2.
The obtained technological progress of the utility model is: overcome the use that existing common ruler causes by length restriction and limited to, be easy to carry again simultaneously and settle, that the utility model also has is simple and reasonable, cost is low, long service life and on-deformable advantage.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is that the utility model A-A is to view.
Fig. 3 is that the utility model B-B is to view.
The specific embodiment
The utility model is described in further detail below with reference to drawings and Examples: as Fig. 1,2, shown in 3, telescopic ruler, form with secondary chi 2 by the main scale 1 that is parallel to each other, wherein main scale 1 one end proximal ends are provided with limited post 3, limited post 3 places by a nut and is fixed on the main scale 1, limited post 3 top screw threads have connected catch 4, offer bar hole 5 on the secondary chi 2, limited post 3 on the main scale 1 places in the bar hole 5 of secondary chi 2, secondary chi 2 is slidingly matched by limited post 3 and main scale 1, described main scale 1 also offers the groove 6 that secondary chi bottom can be embedded with respect to secondary chi 2 shapes, and the scale of described main scale 1 is terminal corresponding with the scale top of secondary chi 2.
