CN201688782U - Counting tapeline - Google Patents

Abstract

A counting tapeline consists of a counter, a wire spool, a wire and a hook. The wire spool is connected with the counter through a roller, the wire is wound on the wire spool, one end of the wire is fixed on the wire spool while the other end is connected with the hook, and the counter is a miniature five-figure gear driving counter. During measurement, the wire is released to drive the wire spool to rotate so as to drive the counter to record rotation data of the wire spool, and the diameter of the wire spool is fixed so that the length of a rotation circle of the wire spool can be determined, thereby realizing a length measurement function through reading of the counter. As the counting tapeline adopts the thin winding wire rather than a wide tape with scales, the length of the wire capable of being wound on the wire spool is greatly larger than that of a tape capable of being wound in a common tapeline box. The counter and the wire spool of the counting tapeline can be combined, the length of the wire on the wire spool can be recorded through the counter, and then longer distances can be measured. In addition, the counting tapeline is convenient in operation and accurate in measurement.

Description

The numeration tape measure

Technical field:

The utility model relates to physical field, relates in particular to length-measuring appliance, particularly a kind of numeration tape measure.

Background technology:

In the prior art, the tape measure kind is a lot, and traditional leather measuring tape, steel tape are arranged, and also has multifunction flexible rule of subsidiary level meter, counter, compass, torch or the like.Conventional tape measure is made up of shell, spool and the belt, the steel band that have a standard scale, and multifunction flexible rule is to realize one-object-many-purposes by additional function, there is no change on measuring method.Need to measure long apart from the time, in surveying such as engineering, need to measure distance usually greater than 100 meters, existing tape measure does not possess and not have so big range, so can't use.Though laser range finder can be measured longer distance, can only measure air line distance, not the energy measurement length of curve.

Summary of the invention:

The purpose of this utility model is to provide a kind of numeration tape measure, and described this numeration tape measure will solve in the prior art the little and technical matters of the longer distance of energy measurement not of tape measure range.

This numeration tape measure of the present utility model, constitute by register, wire spool, coiling and hook, be provided with an input roller bearing in the described register, wherein, described wire spool is arranged on the described input roller bearing, described wire winding ring is on wire spool, and an end of coiling is fixed on the wire spool, and described hook is connected on the other end of coiling.

Further, described register is miniature five-digit number gear drive counter.

Further, the annular U type groove is set on the excircle of described wire spool, described coiling is arranged in the described U type groove.

Further, the wire spool center of circle is 16.65cm to the distance of U type groove bottom land.

Further, described coiling is wire or formal wire.

Principle of work of the present utility model is: during measurement, discharge coiling, coiling drives wire spool and rotates, and then drive register record length data, because the diameter of wire spool is certain, so its length of rotating a week knows, such as when the wire spool radius is 16.65cm, its distance that circles is 1 meter, thereby realizes the function of linear measure longimetry by the reading of register.Owing to use the wide tape measure carefully wind the line rather than to have scale, thus wire spool can around line length be much higher than the tape measure that can curl in the ordinary tape measure box.

The utility model and prior art are compared, and its effect is actively with tangible.The utility model combines register with wire spool, write down the length that winds the line on the wire spool by register, and then can measure long distance, and is easy to operate, measures accurately.

Description of drawings:

Fig. 1 is the structural representation of numeration tape measure of the present utility model.

Embodiment:

Embodiment 1:

As shown in Figure 1, numeration tape measure of the present utility model, by register 1, wire spool 2, coiling 3 with link up with 4 and form, being provided with input roller bearing 5, wire spool 2 in the register 1 is connected with register 1 by input roller bearing 5, coiling 3 is surrounded on the wire spool 2, one end of coiling 3 is fixed on the wire spool 2, and the other end of coiling 3 is connected with hook 4, and hook 4 is used for fixing measures the source.

Further, register 1 is miniature five-digit number gear drive counter.

Further, wire spool 2 excircles are provided with annular U type groove 21, coiling 3 is arranged in the U type groove 21, wire spool 2 centers of circle are 16.65cm to the distance of U type groove 21 bottom lands, at this moment, the length that wire spool 2 circles is 1 meter, and the product by the reading on the register and this length value just can obtain measured lengths.

Further, coiling 3 is wire or formal wire, can also be other wear-resisting, durable rigid line or flexible cords such as ceramic thread.

In an embodiment of the present utility model, the numeration tape measure is when measuring, by winding the line 3 release, driving wire spool 2 rotates, and then drive register 1 record length data, because the diameter of wire spool 2 is certain, so its length of rotating a week knows, thereby realizes the function of linear measure longimetry by the reading of register 1.Owing to use the wide tape measure carefully wind the line rather than to have scale, thus wire spool can around line length be much higher than the tape measure that can curl in the ordinary tape measure box.
