Abstract

The present invention relates to a safe and reliable earth brake of which the fixing pedal rod and fixing releasing fixing pedal rod are not crossed. Even the finger or article, etc. enters the space between the fixing pedal rod and the fixing releasing fixing pedal, the finger or article is not clamped with strong force. The earth brake comprises the following components: a bracket part which isprovided with a plate-shaped support part at the upper end and is offset upwards and is elastic; the fixing pedal rod which has an approximate V-shape and is articulated on the bracket part by a first pin and simultaneously gets across the bracket part extending frontwards and backwards; a fixing releasing pedal rod which is parallely installed at the outside of fixing pedal rod and has a back side that is articulated inside the supporting part through a second pin; and a connecting sheet which is positioned between the second pin and the fixing pin. The back side of fixing pedal rod is installed with a fixing pin which can engage with the bracket part, and the front side is installed with a pedal part.

Description

technical field [0001] The present invention relates to an improvement of a floor brake for fixing a wheelbarrow equipped with a wheel portion such as casters at a desired position. Background technique [0002] In the past, the ground brake, for example, as shown in No. 53-52767, includes: a cylindrical bracket; a pressure rod lifting body that can be lifted coaxially with respect to the cylindrical bracket; A compression spring that biases the lifting body of the pressing rod upward; a shaft protruding outward from the shaft end that is arranged transversely to the above-mentioned bracket; a locking pedal rod that is freely swingably connected around the above-mentioned shaft, and has a The pedal part has the first pin parallel to the above-mentioned axis at the other end, and also includes a ㄑ-shaped arm formed between the above-mentioned pedal part and the first pin; The second pin is arranged parallel to the first pin through the bearing receiving piece at the bottom; ...
