Abstract

The present invention provides a measuring tape with the self-locking type braking mechanism which can reduce the impact upon stopping the tape while winding up the tape having pulled out, is excellent in keeping the tape in the halting condition, and can reduce the resistance upon pulling out the tape. The brake operation means at least comprises a brake operation button operable from an outside of a housing, a braking roller formed of a elastic material connected to the brake operation button for applying a potential energy to a tape in braking direction via leaf spring. The braking roller is wedged between an upper surface of the tape coming out of a rotation drum and a predetermined member above the tape to apply the brake to the tape.

Description

technical field

[0001] The invention relates to a tape measure, which has a brake mechanism in an automatic locking mode, and the brake mechanism can make the pulled-out tape automatically stop at the pulled-out position. Background technique

[0002] In the prior art, the brake of the tape on the measuring tape is mostly used in the following way, that is, after the tape is pulled out from the casing, the brake is operated to stop the tape at the pulled-out position. Wherein, the ruler tape brake also adopts the automatic locking mode, and when adopting this mode, the ruler tape can be automatically stopped at the position after it is pulled out from the housing.

[0003] This automatic locking method has the following form, that is, the tape is stopped by braking the rotating reel that is endowed with potential energy along the rewinding direction of the tape; Insert a stopper between the surface of the tape wound on the rotating reel to stop the tape. The method of inse...
