Description

Rotary components mechanism is used in folding

Technical field

The utility model is related to a kind of folding rotary components mechanism.

Background technology

The engineering goods such as folding cart, generally require to use rotating mechanism, but existing mechanism is it cannot be guaranteed that the height of work Effect is carried out, it is necessary to further be improved.

The content of the invention

The purpose of this utility model is to provide a kind of rational in infrastructure, good folding rotary components of easy to use, effect Mechanism.

Technical solution of the present utility model is：

One kind folds and uses rotary components mechanism, it is characterized in that：Including fixture, fixture passes through first axle and upper rotating part Part is connected, and upper rotary part is in the form that can be rotated around first axle；Fixture is connected by the second axle with lower rotary part, backspin Rotation member is in the form that can be rotated around the second axle；Upper rotary shaft is on upper rotary part, and upper rotary shaft is in can be in upper rotating part The form rotated freely in the axis hole of part；Shaft is arranged on lower rotary part, and Shaft is in can be in lower rotation The form rotated freely in the axis hole of part；

Upper rotary part is connected with lower rotary part by connecting rod, and the rotary motion of upper rotary part can be driven by connecting rod The rotation of lower rotary part；

Under upper rotary part and lower rotary part coincidence status, the convex-concave surface that upper rotary shaft passes through both with Shaft Structure links together.

The utility model is rational in infrastructure, and easy to use, effect is good.

Embodiment

Include handrail 9, pedal, front-wheel 10, trailing wheel 11 using folding cart of the present utility model, the pedal is by front running board 12nd, bumper step 13 is constituted, and being in by rotating shaft between front running board, bumper step can be to the collapsible connection in bottom surface；Set on folding cart The utility model rotary components mechanism 14.

One kind is folded and uses rotary components mechanism, including fixture 1, and fixture is connected by first axle 2 with upper rotary part 3 Connect, upper rotary part is in the form that can be rotated around first axle；Fixture is connected by the second axle 4 with lower rotary part 5, lower rotation Part is in the form that can be rotated around the second axle；Upper rotary shaft is on upper rotary part, and upper rotary shaft 7 is in can be in upper rotary part Axis hole in the form that is rotated freely；Shaft 8 is arranged on lower rotary part, and Shaft is in can be in lower rotating part The form rotated freely in the axis hole of part；

Upper rotary part is connected with lower rotary part by connecting rod 6, and the rotary motion of upper rotary part can pass through connecting rod band The rotation of dynamic lower rotary part；

Apply in above-mentioned folding cart, fixture connects the front running board of dolly；Upper rotary shaft connects the handrail of dolly；Under Rotary shaft connects the front-wheel of dolly.

During folded state, upper rotary part and fixture are substantially vertical, upper rotary shaft then substantially parallel fixture, at this moment help Hand should be folded near upper pedal, and the axis direction of Shaft is substantially consistent with fixture direction, and front-wheel is located at pedal Front end.

Upper rotary part starts rotary expansion (rotation can also be driven by power), while being driven down by connecting rod Rotary part is rotated simultaneously.

During fully expanded position, upper rotary part is substantially parallel with fixture, upper rotary shaft then substantially vertical fixture, this When handrail should substantially vertical upper pedal, lower rotary part overlaps with the face of upper rotary part, the substantially vertical fixation of Shaft Part, while substantially vertical upper pedal, upper rotary shaft and Shaft coaxial line.

In the state of being fully deployed, upper rotary shaft and Shaft coaxial line and interconnection, upper rotary shaft and lower rotation Axle is linked together by both convex-concave surface structures, and rotary shaft can drive rotary shaft revolve simultaneously simultaneously in rotation Turn, you can to reach that rotating handrail drives the purpose of front-wheel rotation control direction.
