Anti-shaking commodity shelf for renting and selling machine

Abstract

The invention discloses an anti-shaking commodity shelf for a renting and selling machine. The shelf comprises a frame body, two groups of chain wheels are arranged on two sides of the frame body; a chain is arranged on each group of chain wheels; a first guide groove and a second guide groove are formed in outer sides of the two groups of chain wheels correspondingly. Each of the first guide groove and the second guide groove is composed of a semi-arc groove, a smooth transition arc groove and a vertical groove. Semi-arc grooves are located in the two ends, vertical grooves are located in middle, and smooth transition arc grooves are located between the semi-arc grooves and the vertical grooves. The centers of semi-arc grooves of the first guide groove and the second guide groove and thecenters of the chain wheels are respectively eccentric up and down and left and right; eccentric distances are X, suspension frames are rotatably arranged on the chains, positioning arms are rotatablyarranged on the suspension frames, guide wheels are arranged at ends of the positioning arms, the guide wheels are matched with the first guide groove and the second guide groove, the length of the positioning arms is X, and the two corresponding positioning arms are perpendicular to each other.

Problems solved by technology

[0002] Chinese patent 2019205126324 is a new type of circular mobile bookshelf book vending machine applied by the applicant on April 16, 2019, which includes a circular book shelf, which does not solve the problem of shaking caused by the offset of the center of gravity of the book shelf

[0003] Chinese patent 2019205126343 is a circular storage rack that the applicant applied for on April 16, 2019. Guide rails are used to solve the problem of preventing the rack from shaking due to the offset of the center of gravity. It is relatively simple to set guide rails to limit the running track and avoid shaking. structure, but setting guide rails will affect other components when the arc is bent, for example: setting the guide rail inside the sprocket is not easy to fix, and setting the chain outside the sprocket will block the operation of the storage table

The above problems are solved, but it requires high machining accuracy, otherwise there will still be slight shaking in the arc track

Moreover, since the positioning arm is directly installed on the chain, the passing radius is small, and a large distance is required between the cargo baskets, otherwise the cargo baskets will interfere with each other when cornering, making it impossible to corner
