Description

Standable gauge wheel

The present invention relates to a metering device characterized by a mechanical method, and more particularly to a standable range wheel capable of stabilizing an upright position.

A distance measuring wheel is a device for measuring the distance on the ground. It is often used in the scene of a traffic accident and is used to measure the length of the track, or to measure the length of the line when the road marking is carried out. Or it can be applied in various fields such as pipeline layout, land measurement, construction engineering, and interior decoration.

The distance measuring wheels sold on the market can be generally divided into a measuring wheel with a single rotating wheel and a measuring wheel with a double rotating wheel. The measuring wheel with a single rotating wheel is usually on the rear side of the measuring wheel or the rotating wheel. The opposite side is provided with a support frame, so that the measuring wheel with a single rotating wheel can be placed upright for convenient storage and access;

Compared with a measuring wheel with a single rotating wheel, a measuring wheel with a double rotating wheel has better balance characteristics because it has two rotating wheels; however, the measuring wheel with double rotating wheels still cannot stand independently. Still relying on the support such as the wall to stand upright, and relying on the support wheel with the double-rotor, the angle between the grip and the support will change the two wheels once the angle between the grip and the support is slightly changed. Rotating to cause the gauge wheel with double wheels to fall.

In order to solve the existing measuring wheel with a double revolver, it cannot stand independently and must rely on the support to be placed upright. The present invention provides a standable distance measuring wheel which is provided with a supporting member on the lower surface of the mounting seat to abut against the ground, so that the measuring wheel with the double rotating wheel can be independently and erected for the purpose of Creation is more convenient in storage and access.
