Stair balance adjuster

This creation is about a stair balance adjuster, especially a stair balance adjuster that uses a simple control mechanism to greatly improve convenience, safety and adjustment accuracy.

Ladder is one of the common tools used in today's society. Its types and styles are numerous. According to the material, it can be divided into bamboo, wood, steel or aluminum alloy. The common ladders include vertical ladders and folding ladders. However, the most important thing when using a ladder is the stability of the ladder legs, and it must be balanced against the anti-slip effect to avoid the problem of uneven sinking or sliding during use.

However, the use of ladders on a generally flat surface makes it easier to adjust the balance of the ladder. It is only necessary to pay attention to whether the ladder legs are stable and slip-proof. However, if the road is not flat or has an inclined angle, the vertical ladder and the folding ladder cannot be used. Use, or must rely on human support, but still high risk. Therefore, a regulator that maintains the balance of the stairs is created, thereby enabling the ladder to be used on a variety of different road surfaces.

The conventional stair adjuster has a base frame, a top frame portion and an adjusting mechanism. The top frame portion is pivotally connected to the base frame and is provided for receiving a stair. The base frame has a grounding mechanism to When the ground is connected, the adjusting mechanism is engaged with the top end of the base frame to adjust the state of its fixation and movement. When in use, the stairs are first locked to the stair adjuster and placed on the ground to be used. At this point, the stair adjuster will adjust itself to the angle of inclination of the ground, so that the stairs are balanced and the user can climb and use. However, such a stair adjuster does not have any The fixing mechanism is to ensure that the stair adjuster is clamped at a certain angle when climbing, and it is easy to cause displacement of the stair adjuster due to external force collision or unstable center of gravity during use, and the use of the stair adjuster safe question.
