Abstract: An improved brake structure of a tape measure mainly includes a pair of corresponding slide slots which are set at the inner side of one side of the upper housing and the lower housing of a tape measure, a pair of lodging troughs extended from the end portion, which are near the outlet of the tape, of the sliding slots, a pair of slide ways at both sides of the control part combined in slide slots to slide in the slide slots, a slide piece extended from the front end portion of the control part, a pair of lodging blocks extended from both sides of the center of the slide piece, and an inset hole set at the front end of the slide piece. The lodging blocks are hold to the upper edge of the lodging troughs. Below the slide slots of the enclosure, a position pair of columns is set at one side to be combined with a brake part. A guide piece of the brake part is inset into the inset hole at the front end of the slide piece. When the control part moves downward, the slide piece also moves downward to make the lodging blocks of the slide piece clipped into the lodging troughs of the enclosure and drive the brake part to turn in a certain angle such that the brake part holds to the surface of the tape to achieve the purpose of braking the tape.

Abstract translation: 卷尺的改进的制动结构主要包括一对相应的滑动槽，其设置在上壳体的一侧的内侧和卷尺的下壳体，从端部延伸的一对倒伏槽， 在滑动槽的出口附近，控制部分两侧的一对滑动导轨组合在滑动槽中，以在滑槽中滑动，从控制部分的前端部分延伸的滑动件 ，一对从滑块的中心的两侧延伸的倒伏块，以及设置在滑块前端的插入孔。 倒伏块保持在倒伏槽的上边缘。 在外壳的滑槽下方，将一对列设置在一侧以与制动部件组合。 制动部件的引导件插入到滑块前端的插入孔中。 当控制部分向下移动时，滑块还向下移动，使滑块的倒伏块夹在外壳的倒伏槽中，并驱动制动部分以一定角度转动，使得制动部分保持在表面 的磁带来达到制动磁带的目的。
