Description

Horizontal bar on door

Technical Field

The utility model belongs to the technical field of body-building apparatus, in particular to horizontal bar on door.

Background

When the horizontal bar on the door is used, the fixing heads at two ends are tightly propped against the door to fix the horizontal bar. With the improvement of living standard and the attention on fitness training, the use of horizontal bars on doors is more and more popular.

The safety performance of the horizontal bar on the door during use mainly depends on the tight pushing relation between the fixing heads on the two sides and the door, and the horizontal bar on the door is fixed between the door frames by using friction force and provides upward supporting force for people; in the training process, because the people need carry out continuous action in the pull-up process, the downward force that the horizontal lever piece received on the door constantly changes, when the atress is the biggest, the maximum power that the member received can greatly exceed human self weight, and the power that increases suddenly probably surpasss the frictional force between horizontal bar and the door and makes horizontal bar on the door be difficult to rely on frictional force to continue to fix on the door to lead to danger.
