Abstract

The utility model relates to a band tape, which comprises a band tape box and a band tape belt which is arranged in the band tape box, wherein, the band tape belt can be flexed from a band tape box opening of the side part of the band tape box. The utility model is characterized in that a rolling wheel is arranged at the position of the band tape box opening of the band tape box, the telescopic direction of a rotating shaft of the rolling wheel is parallel to the telescopic direction of the band tape belt, the rolling wheel is rotationally embedded in a groove at the side wall of the band tape box through a pin shaft, the outer edge thereof is extended outside the groove, the root part of the groove at the side wall of the band tape box is provided with a long and narrow hole, a pen core of which the tail part is mutually supported and pushed by a spring is arranged in the hole, and the head part of the pen core is always pushed with the periphery of the rolling wheel under the action of the spring. Because the utility model is provided with the rolling wheel which can be rolled in one side direction, the rolling wheel can be rolled on the measured object by the way at the side moving measuration time, and meanwhile, a coloring material on the pen core is attached at the edge of the rolling wheel through the friction between the pen core and the rolling wheel, and the surface of the measured object automatically leaves a rolling mark as a marker through the rolling wheel rolling. If the utility model uses the rolling wheel with the materials, such as diamond grain, etc., the utility model can simultaneously be used for cutting glass or tiles at the measuring time.

Description

Tape measure

Technical field

The utility model relates to a kind of tape measure, relates in particular to a kind of tape measure of being convenient to be displaced sideways measurement, more relates to a kind of tape measure that can mark when measuring.

Background technology

Tape measure has become one of indispensable instrument of staff of a lot of industries as a kind of survey instrument that is easy to carry about with one, existing tape measure generally is made of chi box and chi band, in the chi box chi tape wrapping in a wheel hub on, the bending tongue piece of chi band head then is stuck in outside the ruler box mouth.According to existing tape measure structure, the traverse measurement that it is suitable for the flexible direction of chi band also is that the user can draw the chi band edge to measure in the limit, but need be displaced sideways the occasion of measurement at some, with regard to underaction, cut the parallel edges of glass, be exactly like this around the arc measuring in the fixing center of circle etc. as sanction.On the other hand, often need be when measuring at the length place that measures mark in addition, by existing tape measure, the user must use a mark separately, and when practical application, often not on hand.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of tape measure of being convenient to be displaced sideways measurement at above-mentioned prior art present situation.

Another technical matters to be solved in the utility model is that a kind of tape measure that can mark when measuring is provided at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: tape measure includes the chi box and is positioned at its chi band, the chi band can go out flexible from the ruler box mouth of chi box sidepiece, it is characterized in that the chi box is provided with a roller in the position of its ruler box mouth, the rotating shaft of this roller is parallel with the flexible direction of chi band.

Described roller can be embedded in the groove of chi box sidewall rotationally by a bearing pin, and its outer rim is exposed to outside the groove.

Above-mentioned tape measure in use, serve as a mark needing mark slightly firmly to press down to stay an impression on the surface of testee with roller, but better, be that root of notch at described chi box sidewall has a long and narrow hole, the pen core that one afterbody is offseted by a spring-loaded is set in this hole, and the head of pen core then offsets with the periphery of roller under the effect of spring all the time;

Described pen core can pencil-lead or other pigmentable pen cores.

Groove and long and narrow hole on the above-mentioned chi box sidewall can directly be processed on the chi box, also described roller, pen core and spring thereof can be installed in one earlier and have in the pedestal of groove and long and narrow hole, then pedestal are fixed on the ruler box mouth position of chi box.

Compared with prior art, but the utility model is owing to be provided with the roller of a side rolling, therefore when being displaced sideways measurement, this roller can be taken advantage of a situation and be rolled on testee, simultaneously, friction between pen core and the roller sticks to the roller edge with the coloring material on it, and the rolling by roller stays roller marks automatically and serves as a mark on the surface of testee.If select the roller of material such as emery for use, then when measuring, also can be used to glass-cutting or ceramic tile.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1, shown in Figure 2, be embodiment one of the present utility model, include chi box 1 and the chi band 2 that is positioned at it, chi band 2 can go out flexible from the ruler box mouth of chi box 1 sidepiece, chi box 1 has a groove 11 in the sidewall locations of its ruler box mouth, be embedded with a U type metal liner frame 5 in it, described roller 3 promptly is sandwiched between two sidewalls of this metal liner frame 5 and can rotates to it, its outer rim is exposed to outside the described groove 11, bearing pin 4 runs through the center pit of roller 3, and its two ends are run through respectively and embedded chi box wall after the support holes corresponding on two sidewalls of described metal liner frame 5 and fix.

As shown in Figure 3, be embodiment two of the present utility model, different with embodiment one is, groove 11 roots at described chi box sidewall also have a long and narrow blind hole 12, in this hole 12, be provided with a pencil-lead 6 and a spring 7 certainly outside to inside, the root of pencil-lead 6 and spring 7 offset, and the head of pencil-lead 6 then offsets with the periphery of roller 3 under the effect of spring 7 all the time.

As shown in Figure 4, be embodiment three of the present utility model, different with embodiment two is, described roller 3, pencil-lead 6 and spring 7 thereof are installed in the pedestal 8 with groove 81 and long and narrow hole 82, then this pedestal 8 are fixed on the ruler box mouth position of chi box 1 by side bonding, front screw 8 fixing modes.In the present embodiment, this pedestal 8 adopts metal materials, therefore need not to be provided with U type metal liner frame in its groove 81 again, and its long and narrow hole 82 is a through hole, and 7 compressions when mounted of spring also are against its root on the step of chi box 1 sidewall relevant position.
