Chorus platform for prior art lacks safety lock, has the problem of certain potential safety hazard, the utility model proposes a kind of chorus platform, can prevent the guardrail rotational angle in use of chorus platform, lose protective effect.
The technical solution of the utility model is achieved in that
A kind of chorus platform, comprise main support, described main support is connected with some pedal supports by pivot, the top movable of described main support is hinged with guardrail, described pedal support is provided with pedal, be provided with fastening devices between described main support and described guardrail, described fastening devices comprises the fixed pin holes be arranged on described main support and described guardrail and the night bolt be arranged in fixed pin holes.
Further, the bottom surface of described main support is provided with wheel, and described wheel is provided with brake gear.
Further, equal rational height adjusting device on the supporting leg on described first floor pedal support and described wheel.
Further, described main support is provided with gag lever post, described gag lever post is arranged on the front of described main support pivot hole, and described gag lever post rear surface is equal with the distance of pedal support pivot hole with described pedal support soffit with the distance of described pivot hole.
Further, the supporting leg of described pedal support is provided with plastic casing-pipe.
The beneficial effects of the utility model: by arranging fixed pin holes and night bolt on main support and guardrail, make guardrail can not rotate when using state, and then ensure that the security function of guardrail; And by arranging gag lever post on main support, pedal support can not be rotated when folded state, collision; And by arranging the wheel of brake device in main support bottom surface, laborsaving, convenient when chorus platform entirety is carried.
