Problems solved by technology
The scroll wheel of the distance measuring pen is small and thin, it is used to measure the map, and it cannot measure long distances
The wheel of the distance measuring wheel is large and the accuracy is low. It is used to measure roads or super long distances. The product is foldable but it is still too large. Compared with the distance measuring pen, it is obvious to carry
Neither measuring tool is suitable for measuring corners, depths, heights and lengths where the product cannot touch
There is also a problem with the measurement method. After the measurement, there is a slight angle between the axis of the connecting rod and the roller, and there will be an error in the measured value.

Embodiment
[0037] The circumference of the roller 1 is 30mm. When the roller 1 rolls a circle, the first conversion gear 2 rotates a circle, and the pinion of the third conversion double gear 4 has the same number of teeth as the first conversion gear 2. Therefore, the second conversion gear When 3 shifts to the third conversion double gear 4, the third conversion double gear 4 also rotates one turn, and the transmission ratio of the pinion gear of the fourth conversion double gear 5 and the large gear of the third conversion double gear 4 is 1:3, then The fourth conversion double gear 5 rotates 3 times, through the conversion of the fifth conversion gear 6, the sixth conversion gear 7 drives the nearest millimeter counting gear 8 to rotate 3 times, and then drives the centimeter counting through the conversion of the decimal gear 11 The gear 8 rotates 3 / 10 circle, and the number display is 3, which is 3cm. When the measurement is over, press the reset button 9, and the reset button 9 co...

The portable distance-measuring wheel of the present invention belongs to the technical field of measuring tools; the technical problem to be solved is to provide a portable distance-measuring wheel that is easy to use, quickly cleared, and has a wide measurement range; the technical solution adopted is: the first conversion gear and The second conversion gear meshes, the second conversion gear meshes with the pinion gear of the third conversion double gear, the large gear of the third conversion double gear meshes with the pinion gear of the fourth conversion double gear, the large gear of the fourth conversion double gear, the third conversion double gear The six conversion gears are all meshed with the fifth conversion gear, and multiple decimal gears and multiple counting gears are arranged at intervals; a reset button is connected to the shaft on which the decimal gear is installed, and the reset button protrudes from the hole opened on the shell. A reset shift fork is also connected, and reset cams are arranged on the plurality of counting gears, and the reset shift fork cooperates with the reset cam; a telescopic rod is installed on the outer side of the shell, and the present invention is especially suitable for measuring indoors during decoration. size.
Description
technical field [0001] The invention relates to a portable distance-measuring wheel, which belongs to the technical field of measuring tools. Background technique [0002] At present, there are two kinds of tools for measuring with a roller: a distance measuring pen and a distance measuring wheel. The small and thin scroll wheel of the distance measuring pen is used to measure the map and cannot measure long distances. The distance measuring wheel has a large scroll wheel and low accuracy. It is used to measure roads or ultra-long distances. The product is foldable but still too large. Compared with the distance measuring pen, it is obvious to carry. Neither measuring tool is suitable for measuring corners, depths, heights and lengths where the product cannot touch. In addition, due to the problem of the measurement method, there will be errors in the measurement value if there is a slight angle between the axis of the connecting rod and the roller after the measurement. ...
