Description

an electronic tape measure

technical field

The utility model relates to the field of measuring tapes, in particular to an electronic measuring tape.

Background technique

A tape measure is a commonly used length measuring tool in people's life and work. It can be rolled up manually or automatically for easy storage. Compared with the traditional tape measure, which requires manual reading of the value on the tape, there is currently an electronic tape measure with a sensor installed in the housing, which automatically recognizes the length of the tape being pulled out, and then displays it on the display screen, which can overcome the visual impact of manual reading. However, this kind of tape requires that the outlet of the tape on the casing should be close to the measurement point when measuring. In some places where the space is relatively small, it may not be possible to close the casing to the measurement point. Pull out a section of the tape, and use a part of it close to the measuring point. The value obtained from the sensor is greater than the actual value, and it can only be read manually.

Contents of the invention

The technical problem to be solved by the utility model is to provide an electronic tape measure, which can solve the problem that the existing electronic tape measure can only be read manually when the housing is limited by the space and cannot be close to the measurement point.

The utility model is realized through the following technical solutions:

An electronic tape measure, comprising a tape extending outward from a casing, the tape is provided with a code; it also includes a fingertip, the fingertip of the fingertip is provided with a micro switch and a code reading mechanism, the The finger cover is also provided with a control unit, a display screen, a communication module and a battery. When the control unit receives the switch signal from the micro switch, it reads the code through the code reading mechanism to obtain information, displays the information through the display screen, and Send to the receiving end through the communication module.

A further solution of the present utility model is that the fingertip is also provided with a USB interface, and the USB interface is connected to the communication terminal of the control unit and the charging input terminal of the battery; the charging is convenient, and the data can also be read through the data line, and the use convenient.

A further proposal of the utility model is that the joints of the finger cots are made of elastic sleeves; they can be bound on the fingers for positioning when worn to prevent falling off, and are convenient for knuckle movement, and can also be stretched to adapt to different finger lengths. Thick and thin people use.

A further solution of the utility model is that the micro switch and the code reading mechanism are arranged side by side along the nail of the finger, and the relative angle between the nail and the tape is easy to control, which is conducive to improving the accuracy of reading.

Compared with the prior art, the utility model has the following advantages:

After the tape is attached to the measuring point, press the micro switch on the fingertip to start the code reading mechanism to read the code at the corresponding position, which effectively overcomes the space limitation on the tape measure housing and improves the reading accuracy.

Detailed ways

A kind of electronic tape measure as shown in Figure 1 and Figure 2, comprises the tape 1 that extends outwards from the casing, and code 2 is arranged on the tape 1; Also includes finger cot 3, and described finger cot 3 preferably For the thumb, it includes the first knuckle cover, the joint part 11, and the second knuckle cover connected in sequence. The rear end of the second knuckle cover is also provided with the back of the hand display part. Both the knuckle cover and the display part of the back of the hand are made of plastic, wherein the second knuckle cover and the display part of the back of the hand are integrally injection molded, and the joint part 11 is made of an elastic sleeve, which can be made of rubber or elastic cloth. The two ends are glued on the outer wall or inner wall of the first knuckle cover and the second knuckle cover; the fingertip of the first knuckle cover is provided with a micro switch 4 and a code reading mechanism 5 side by side along the nail of the finger, The surface of the display part on the back of the hand is inlaid with a display screen 7 and a USB interface 10, and a control unit 6, a communication module 8, and a battery 9 are arranged inside, the micro switch 4, the code reading mechanism 5, the display screen 7, and the USB interface 10 , the communication module 8 and the battery 9 are respectively connected to the control unit 6; when the control unit 6 receives the switch signal sent by the micro switch 4, it reads the code 2 to obtain information through the code reading mechanism 5, and displays the information through the display screen 7, And the information is sent to the receiving end through the communication module 8, the battery 9 provides power for the system, and the USB interface 10 is used for the control unit 6 to connect the USB data line for data communication and to charge the battery 9.

In this embodiment, the control unit 6 uses a STC15W4K60S4 single-chip microcomputer, the communication module 8 uses a GSM A6 wireless communication module, the display screen 7 uses a MGLS12864T type, and the micro switch 4 uses a LAXXSCOM brand 6*6* The 4-pin switch of 7, the USB interface 10 uses the TELESKY brand USB female seat, the code reading mechanism 5 uses the probe of the existing point reading pen, the common CMOS camera for image recognition, and the induction electromagnetic coil , the code 2 on the ruler tape 1 adopts the type that matches the probe, for example: the code reading mechanism 5 adopts a CMOS camera, then the code 2 adopts a two-dimensional shallow code printed or engraved on the ruler tape 1; the code reading mechanism 5 adopts For the electromagnetic coil, the code 2 adopts the identification code printed by conductive ink under the surface of the non-metal ruler tape 1 .
