Abstract

The utility model relates to a three-image turning display device which comprises a body (1), a panel (2), a panel end frame (3) with a shaft, a crank arm (4), a connecting rod (5), a driving gear, a motor, and a speed reducer. The key technology is that a machine intermittent mechanism is driven by the motor and the speed reducer to repeat a ' turning-displaying' motion at a stable speed. The utility model which is particularly suitable for transmitting message and pictures in the public places can be widely used for renewal of generation of the existing billboard.

Description

Three-image auto-turning display device

The utility model relates to a kind of billboard, belongs to advertisement, information, picture transmission equipment, is applicable in various public places and transmits advertisement, information and various pictures.

An existing display board or single fixed image is only arranged, or adopt large screen television, the cost height, the operation fees of maintenance are big, are difficult for promoting.Transmit information with the computer billboard, also have the cost height, the demonstration amount is few, can not transmit deficiencies such as picture.

The purpose of this utility model is to improve above-mentioned technical deficiency part, and provides a kind of three-picture automatic overturn display device, with relative very cheap price and running cost, increases the quantity of transmission information, and multi-picture is provided, and automatic flip displays.

Task of the present utility model is finished by following approach: in the inside of the automatic overturn display device of three-picture, by the power drive mechanism of forming by curved arm rod mechanism, mechanical indexing mechanism, steady arm, motor and speed reduction unit etc., adopt this physical construction, make the display board that a single fixed image is only arranged realize unmanned, automatically upset regularly, rapidly,, multi-picture is provided, increases the quantity of transmission information.

The utility model has the following drawings:

Fig. 1 is the utility model front elevation (also being the accompanying drawing of specification digest), and wherein 1 is the display device body, the 2nd, and the panel monomer.

Fig. 2 is the utility model schematic rear view, and wherein 1 is body, the 3rd, and the panel end frame of tape spool, the 5th, connecting rod, the 6th, follower gear, the 7th, driving gear, the 8th, upper transfer gear, the 9th, lower transmissioning gear, the 10th, synchronous cog belt, the 11st, motor and speed reduction unit, the 12nd, middle riser, the 13rd, left riser, the 14th, the bearing pin of band steady arm.

Fig. 3 is that synoptic diagram is looked on the utility model left side, and wherein 1 is body, the 2nd, and the panel monomer, the 3rd, the panel end frame of tape spool, the 4th, crank arm, the 5th, connecting rod, the 6th, follower gear, the 7th, driving gear, the 8th, upper transfer gear, the 9th, lower transmissioning gear, the 10th, synchronous cog belt, the 11st, motor and speed reduction unit, the 12nd, middle riser, the 14th, the bearing pin of band steady arm.

The utility model will be described in further detail in conjunction with the embodiment that provides in the above accompanying drawing:

Display device front as shown in Figure 1 is a rectangular configuration, body (1) is an angle iron frame, sheet iron is covered on the surface, some independently panel monomers (2) are suppressed by sheet iron, its number is more than one, can be some right, its cross section be an equilateral triangle, and the length of side in its cross section can equal the centre distance in two panel monomers (2) cross section.

The utility model schematic rear view as shown in Figure 2, the number of connecting rod (5) is a pair of, one end of connecting rod (5) is contained on the bearing pin (14) of band steady arm, and be connected with follower gear (6), follower gear (6) is formed mechanical indexing mechanism with driving gear (7), driving gear (7) is a partial gear, when its constant speed is rotated continuously, will realize intermittently rotating with the follower gear (6) of its engagement.The bearing pin (14) of band steady arm be a pair of, and steady arm is that cup head is cylindrical, and back dress cylindrical helical compression spring is when follower gear (6) rotation played the role of positioning during intermittence.Upper transfer gear (8) is connected with key with driving gear (7) is coaxial, is contained between middle riser (12) and the left riser (13).Lower transmissioning gear (9) is with motor and speed reduction unit (11) is coaxial is connected with key.With synchronous cog belt (10) engaged transmission, accurately transmit between upper transfer gear (8) and the lower transmissioning gear (9) with rotating speed and the power that guarantees the output of motor and speed reduction unit (11).

The utility model left side is as shown in Figure 3 looked synoptic diagram and is approximate triangular structure of right angle, the axle head of the panel end frame (3) of tape spool connects crank arm (4), the cross section of the panel end frame (3) of tape spool is an equilateral triangle, its kernel of section overlaps with the kernel of section of panel monomer (2), and with the axle the center overlap.Crank arm (4) for dumb-bell shape, its number is more than one, can be some right, and its number can equal the number of panel monomer (2).Connecting rod (5) front is strip, on some holes of matching with crank arm (4) are arranged, the centre distance in per two holes equals the centre distance in two panel monomers (2) cross section.Connecting rod (5) connects and drives some cranking arm (4) to be done the plane and rotatablely moves synchronously.One end of connecting rod (5) is contained on the bearing pin (14) of band steady arm, and is connected with follower gear (6), follower gear (6) and intermittently engagement of driving gear (7).The material of synchronous cog belt (10) can be a urethane rubber, workplace becomes the teeth groove of profile of tooth and upper transfer gear (8) and lower transmissioning gear (9) to make engaged transmission, strength layer by band bears load, constant with the nodel line length that guarantees band, so do not slide relatively therebetween, transmission efficiency can reach 99.8%.

During the utility model work, motor and speed reduction unit (11) drive lower transmissioning gear (9), lower transmissioning gear (9) drives upper transfer gear (8) by synchronous cog belt (10), upper transfer gear (8) is synchronous with driving gear (7), driving gear (7) and intermittently engagement of follower gear (6), follower gear (6) is passed to connecting rod (5) with mechanical geneva motion, connecting rod (5) drives the panel end frame (3) of some tape spools by some cranking arm (4), thereby drive some panel monomers (2), realize the automatic flip displays of three-picture.

The utility model can be widely used in the technological transformation of existing fixation of advertisement plate.
