How to solve the above-mentioned existing problems and deficiencies is a direction in which the applicant and the related manufacturers engaged in the industry are keenly interested to research and improve.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned shortcomings, the inventor of the present invention has to search relevant data, evaluate and consider in many ways, and design a structure of a rolling door speed reducer with increased safety by using a technology of an impeller and a planetary gear through continuous trial and modification based on years of experience accumulated in the industry.

The utility model discloses a main aim at: the planetary gear is realized by using a power driving piece, a transmission piece and a rotating disc, and the safety in use is improved by matching with an impeller piece.

To achieve the above object, the present invention provides a structure of a rolling door speed reducer, including: the device comprises a shell, a power component connected with one side of the shell, a power driving piece positioned in the shell and connected with the power component, a plurality of driving pieces arranged in the shell and meshed with the power driving piece, a linkage disc arranged in the shell and used for pivoting the driving pieces, a rotating disc movably arranged in the shell, an inner meshing part arranged on the inner side of the rotating disc and used for meshing the driving pieces, an outer meshing part arranged on the outer side of the rotating disc, a transmission rod body pivoted on the shell and meshed with the outer meshing part, an impeller piece arranged on the transmission rod body, an impeller shell arranged on the outer side of the impeller piece, a water inlet part arranged on the impeller shell and corresponding to the impeller piece in position, and a water outlet part arranged on the side of the water inlet part, wherein one side of the linkage disc, which is far away from the driving pieces, is connected with a rolling door.

By adopting the structure, the power driving piece, the transmission piece and the rotating disc can form a structure similar to a planetary gear, and during normal use, the power driving piece can be driven by the power assembly to rotate, and the rotating disc positioned at the outermost side can not rotate at the moment, so that the transmission piece can rotate clockwise or counterclockwise along the power driving piece, when each transmission piece rotates along the power driving piece, the linkage disc can be driven to rotate, and the rolling door can also be driven by the linkage disc to rotate, so that the rolling door can be folded and unfolded.

When the sudden situation occurs inside and the power assembly cannot be controlled, water can be pumped into the impeller shell through the water inlet part, the water flows through the shape of the impeller shell to impact the impeller piece, and then the water flows out through the water outlet part to drive the impeller piece to rotate. Therefore, when the power component can not be used due to the sudden situations such as fire, power failure and the like, the rolling door can be opened through the impeller piece, and the use safety can be improved.

By adopting the technical scheme, the problem of poor safety in use of the existing rolling door can be solved.
