Abstract

The utility model discloses a straight scale with a telescopic scale port. The straight scale is relevant to a measuring tool, the straight scale is convenient to use and is easy to operate, and a knife edge different needs not to be reserved. The straight scale comprises an elongated scale body, wherein a longitudinal through notch is arranged in the scale body near one side of a scale edge. One narrow edge of the telescopic scale port with an I-shaped cross section is arranged in the notch, and the wide edge and other parts of the telescopic scale port with the I-shaped cross section are exposed from the scale port edge of the scale body. A plurality of spring holes are arranged on the groove bottom of the notch, and compression springs arranged in the spring holes are arranged between the telescopic scale port and the groove bottom of the notch. Stopping blocks are plugged at two ends of the notch.

Description

The ruler of band shrinkage-rule mouth

Technical field:

The utility model is relevant with measurer, specifically is meant the ruler of band shrinkage-rule mouth.

Background technology:

The glass of monoblock cut out divide the less shape of share into and need use ruler; The chi body material of the ruler that the processed glass place of extensively seeing is used has plastics, metal, wooden; Be shaped as strip, when using operation generally with left hand by measure the position confirmed good back then the right hand hold the rod glass cutter and be close to the line of chi limit because the rod glass cutter is more special formed; There is the spacing distance of a 2-3mm in its blade point carpenters square limit; Therefore point of a knife is not exactly Bian Kou position but the 2-3mm slightly outward of this strip ruler in the scribing position of glass surface, and the limit mouth of ruler all is whole one with respect to the chi body, can not relatively move; So it is poor to reserve this edge of a knife when the usual way of people is the measurement before sanction is drawn; Or add deduct, the amount that particularly is placed on glass when ruler is crossed on one side or a sideline judge who did not measure when drawing or add deduct and need conscientiously add up to, and is easy to sometimes make mistakes; Though but it is but far not straightforward that this kind way people are accustomed to; If can operation tool do some on such as ruler improve let the operator again with the glass cutter of this rod cut out when cutting a piece of glass as with as the thin sword sheet accurately with straightforward and need not to consider again that what edge of a knife is poor, be undoubtedly a big improvement direction, also be that people particularly cut out the operator who cuts a piece of glass and extremely hope.

Summary of the invention:

The purpose of the utility model is to provide a kind of new technical scheme of ruler promptly with the ruler of shrinkage-rule mouth, and it can solve above-mentioned inconvenience.

Theing contents are as follows of the utility model technical scheme: it comprises the chi body of strip; In chi body, be processed with the notch of vertical perforation near chi limit one side; Device has cross section to be one side, narrow limit of the shrinkage-rule mouth of I shape in the notch, and the broadside of shrinkage-rule mouth and other part are exposed from the chi limit of chi body; On the bottom land of notch, be processed with several spring holes, device has compressing spring in the spring hole, in the shutoff of the two ends of notch sprue is arranged.

The beneficial effect of the utility model is that measurement is straightforward, and it is poor to need not to reserve the edge of a knife.

Description of drawings:

Fig. 1 is the vertical view of the ruler of band shrinkage-rule mouth.

Fig. 2 is the viewgraph of cross-section of the ruler of band shrinkage-rule mouth.

Fig. 3 is the viewgraph of cross-section of the ruler duty of band shrinkage-rule mouth.

Among each figure, 1 is the chi body, and 2 is sprue, and 3 is the shrinkage-rule mouth, and 4 is compressing spring, and 5 is notch.

The specific embodiment:

Like Fig. 1, shown in Figure 2; The chi body 1 of strip be processed with the notch 5 of vertical perforation near chi limit one side, the cross section of notch is the bundle degree of lip-rounding, bundle is one side mouthful towards chi mouth limit; Device has cross section to be one side, narrow limit of the shrinkage-rule mouth 3 of I shape in the notch; Cross section is broadside and other part of the shrinkage-rule mouth of I shape and exposes from the chi limit of chi body, and is as shown in Figure 2, but above also mint-mark go out length scale and numeral; On the bottom land of notch 5, be processed with several spring holes; Respectively install a compressing spring 4 in each spring hole; Compressing spring protrudes from a spring hole part (placing between the bottom land of shrinkage-rule mouth and notch); The glass cutter point of a knife that shrinkage-rule mouth 3 horizontal elasticity activities are designed to rod has sprue to prevent the longitudinally-moving of shrinkage-rule mouth in the shutoff of the two ends of notch simultaneously to the promptly about 2.5mm of distance of cutter head one side (also promptly arrive the chi limit, chi limit with ruler fits together because cutter head one side is actually).So the ruler civilian dress of the design's band shrinkage-rule mouth is put and is finished, and like Fig. 1, shown in Figure 2, the cross section of shrinkage-rule mouth 3 is an I shape; Its narrower one side embeds in the notch 5, on widthwise, controlled by notch, and the elastic force of the compressing spring at the bottom of the notch can make it under no external force effect, be in the most outside position all the time; Extruding shrinkage-rule mouth 3 such as the glass cutter cutter head after the extruding that receives lateral external forces just compresses compressing spring 4 left, one side impel the chi limit that is close to chi body 1 of its broad, the distance that obviously this moment, the shrinkage-rule mouth laterally moved from right to left is exactly the distance of the glass cutter point of a knife of rod to the chi limit; As shown in Figure 3; The position of the glass point of a knife line size that needs of the finished product that cuts a piece of glass of cutting out that gets of initial amount just need not to consider or added deduct edge of a knife difference like this, and is straightforward; Simple and practical, convenient and swift.

Claims

1. ruler with the shrinkage-rule mouth; It comprises the chi body of strip; It is characterized in that in chi body, being processed with the notch of vertical perforation near chi limit one side; Device has cross section to be one side, narrow limit of the shrinkage-rule mouth of I shape in the notch, and cross section is broadside and other part of the shrinkage-rule mouth of I shape and exposes from the chi mouth limit of chi body; On the bottom land of notch, be processed with several spring holes, the compressing spring of device places between the bottom land of shrinkage-rule mouth and notch in the spring hole, in the shutoff of the two ends of notch sprue is arranged.
