Abstract

The utility model discloses a two sided display apparatus with mechanism changing the pictures. Two groups of rotary columns with polygonal surfaces side by side forms two mutual reverse display surfaces. Each rotary column is connected with a dynamical system through an intermittent drive system. The utility model has simple and stable structure. The utility model can disseminate information toward two directions and increase information capacity simultaneously. The utility model can be free to maintain and run in long time.

Description

Two sided display apparatus with mechanism changing the pictures

The utility model relates to the variable picture mechanical display devices, relate in particular to can two-way demonstration variable picture machinery rotary-column type display device.

In the existing display device, fixedly advertisement, the billboard of single width of being generally commonly used, because it can only show a width of cloth picture regularly, capacity is little, and is dull inflexible, can not satisfy growing advertisement far away, propagate the needs of cause.Recently a kind of variable picture mechanical display devices of Chu Xianing, it mainly is made of motor, speed change intermittently-driving system and the faceted pebble rotary column constitutes more than one group indication mechanism.Arrange at each face of many faceted pebbles rotary column and the picture of different content to make it to show within a certain period of time certain combined picture.Behind one section official hour, each rotary column conversion display surface shows the picture of another content.This device can picture displayed be rich in innervation, and certain capacity is arranged.But, existing all be folk prescription to display frame, can only so just make this class display device seem inapplicable in positive display frame in many occasions, the quantity of information of being held is few.

The purpose of this utility model provides the variable picture machinery rotary-column type display device that a kind of twocouese shows.By mixing reliable kinematic train, make the reliability of device, and effect and all greatly raisings of information capacity.

The purpose of this utility model is achieved in that variable picture machinery rotary column two sided display device, and two groups of rotary columns are side by side arranged, and forms the mutual display surface dorsad of two width of cloth.Each rotary column is connected with power system by the intermittently-driving system.Said intermittently-driving system is by reducing gear, the Malta sheave intermittent motion mechanism that is connected with reducing gear, and the synchromesh gear group that driven by Malta sheave intermittent motion mechanism, each rotary column that the synchromesh gear group drives constitutes.The power of said intermittently-driving system output should make the rotary column per minute rotate 5～10 times.

The utility model will be further described below in conjunction with accompanying drawing.Fig. 1 is a principle schematic of the present utility model, and Fig. 2 is a structural representation of the present utility model.In the accompanying drawings, (1) is three faceted pebble rotary columns, and (2) are the synchromesh gear groups, and (3) are sheaves, and (4) are motor, and (5) are train of reduction gears, and (6) are bearings, and (7) are shells, and (8) are cranks, and (9) are locating wheels.With reference to the accompanying drawings, after motor (4) drives train of reduction gears (2), drive the crank (8) of Malta intermittent drive mechanism, drive sheave (3) again, sheave (3) drives synchromesh gear group (2), and each three faceted pebble rotary column (1) is rotated synchronously.Moving 360 ° of crank (8) revolution makes sheave (3) drive synchromesh gear group (2), drives 120 ° of each three faceted pebble rotary columns (1) rotations, i.e. faceted pebble of conversion, and the speed ratio that can change train of reduction gears (5) is determined.The two ends of each three faceted pebble rotary column (1) are bearing in respectively on the bearing (8), and are brisk to guarantee running, and the concave arc section that the convex arc section on the locating wheel (9) of their dependence Malta, location intermittent drive mechanism limits the sheave (3) that cooperates with it guarantees.Three faceted pebble rotary columns (1) are made by rolling " △ " aluminium alloy hollow section bar, to guarantee rigidity, accuracy and weight reduction, add brisk bearing, can guarantee to exempt from for a long time the maintenance operation.

The utility model has greatly improved information capacity, can diffuse information to both direction simultaneously, and is simple in structure firm, can guarantee to exempt from for a long time the maintenance operation.

Claims (3)

1, variable picture machinery rotary column two sided display device, dynamic system is characterized in that having two groups of many faceted pebbles rotary columns side by side, forms the mutual display surface dorsad of two width of cloth, and each rotary column is connected with power system by the intermittently-driving system.

2, variable picture machinery rotary column two sided display device according to claim 1, it is characterized in that said intermittently-driving system is by reducing gear, the Malta sheave intermittent motion mechanism that is connected with reducing gear, constituted by the synchromesh gear group that Malta sheave intermittent motion mechanism drives, each rotary column that the synchromesh gear group drives.

3, variable picture according to claim 1 machinery rotary column two sided display device is characterized in that the power of said intermittently-driving system output should make the rotary column per minute rotate 5～10 times.
