Successive movable type multi-flip billboard

Abstract

The invention discloses a successive movable type multi-flip billboard, comprising a plurality of side-by-side regular square prisms (2), a frame (1) and an operation control driving device; wherein the regular square prisms moves in succession every time to overturn a picture. The device comprises a hinge link mechanism which is provided with a plurality of rockers (6) along the regular square prisms (2) and connecting rods (7) connecting the regular square prisms (2) with the rockers (6) in series by a hinge (9), the other end of each rocker (6) is connected with the frame (1) by a hinge (8), the rockers (6) and the connecting rods (7) at least comprises one rocker (6) connected with at least two connecting rods (7) in series between each two adjacent regular square prisms (2) connected in series, and the position of the regular square prism (2) moving into position previously can be locked by the regular square prism (2) which moves into position subsequently and the rocker (6). Thus, the regular square prisms (2) can not collide owning to out of control of positional accuracy.

Description

technical field [0001] The invention relates to a successively moving multi-faceted flip billboard, in particular to a successively moved multi-faceted flipped billboard which obtains a rotating space by a plurality of side-by-side regular square prisms moving successively in different directions each time. Background technique [0002] Such billboards or devices in the prior art are disclosed by the following patent documents. [0003] Chinese Patent Publication No. cn2627609y, the publication date is July 21, 2004. In the utility model specification, a "four-sided flip-screen display device" is disclosed. The crankshafts on the frame, a regular quadrangular prism positioned on each crankshaft, and corresponding power drive control devices (this type of device is not specifically provided in this specification). Wherein the shaft body of the free end of the crank of each crankshaft is connected with the central axis of a regular quadrangular prism above it, so that each re...

Problems solved by technology

[0004] Due to the need for the quality of picture splicing, the four-sided turning picture rotation display device completes each time the picture is turned over and replaced, the gap between the regular square prisms is very small, and the error of each regular square prism's own position after each movement will lead to The relative position error between it and the adjacent regular prism, thus, a small position error when each movement of each regular prism is completed, may cause it to collide with the adjacent regular prism

At the same time, due to the inertial effect, every time each regular prism moves, it will impact the corresponding parts or devices for stopping its movement and locking its position when its movement is completed, so that each regular prism The position accuracy of each movement is difficult to control, and the collision between the regular square prisms is inevitable, so that it happens frequently, which makes the whole device or billboard unusable

This is the technical bottleneck where such devices or billboards have not been effectively developed until now
