Abstract

The invention discloses a modular three-face turning in the ad domain, which comprises the following parts: motor, upper frame, lower frame, triangular prism rotated by locating shaft between upper and lower frames, bearing seat fixed at corresponding left and right sides in the lower frame, common gear shaft among bearing seats rotatably, wherein the gear shaft connects the motor, which connects the triangular prism through mould unit with cabinet; the gear-pulling wheel is set in the cabinet rotatably with gear connecting the gear shaft; the pulling wheel of the gear-pulling wheel connects cam which is fixed at the bottom of the triangular prism; the driving element can be assembled into a mould unit, which is driven by gear shaft to change element through fetching the destroyed element without repeated labor with convenient maintenance.

Description

Module three-surface

Technical field

The present invention relates to a kind of advertising equipment, relate in particular to a kind of module three-surface.

Background technology

It is important displaying medium in the present domestic outdoor advertising that three faces turn over, because its three pictures can be moved picture certainly, has innervation, economical and practical, at home widespread usage.But, the greatest problem that three faces turn over existence is that drive mechanism is unreasonable, a lot of stepping wheels of dress (referring to Fig. 3, Fig. 4) on the transmission shaft in the machine lower frame, and these stepping wheels all are to be made by plastic material, as easy as rolling off a log distortion, aging, wearing and tearing, in a single day the stepping wheel damages, and needs during replacing stepping wheels all on the transmission shaft is all pulled down, reinstall after the replacing one time, maintenance is trouble very again.

Summary of the invention

The module three-surface that the purpose of this invention is to provide a kind of convenient for maintaining.

For achieving the above object, the technical solution used in the present invention is:

A kind of module three-surface, comprising motor, upper side frame, lower frame, be rotatably installed with tri-prismoid relatively by locating shaft between upper side frame and the lower frame, it is characterized in that: correspondence is installed with bearing seat about in the lower frame, be rotatably installed with elongated gear shaft between the bearing seat relatively, gear shaft is connected with drive of motor; Gear shaft is in transmission connection by module assembly and tri-prismoid, module assembly is rotatably installed with the tooth thumb wheel relatively comprising cabinet is arranged in the cabinet, the gear of tooth thumb wheel is that gear drive is connected with gear shaft, the thumb wheel of tooth thumb wheel is connected with cam, and cam is fixedly mounted on the bottom of tri-prismoid.

The present invention is assembled into a module assembly with actuated element, drives with a rooted tooth wheel shaft, only needs when changing original paper taking off of damaging be need not to carry out the duplication of labour, and is easy to maintenance.

Embodiment

Below in conjunction with the drawings and specific embodiments the present invention is further described:

A kind of module three-surface, as shown in Figure 1 and Figure 2, comprising motor 8, upper side frame 1, lower frame 6, be rotatably installed with tri-prismoid 3 relatively by locating shaft 2 between upper side frame 1 and the lower frame 6, correspondence is installed with bearing seat 4 about in the lower frame 6, be rotatably installed with elongated gear shaft 7 between the bearing seat 4 relatively, gear shaft 7 is connected for chain drive with motor 8; Gear shaft 7 is in transmission connection by module assembly 5 and tri-prismoid 3, module assembly 5 is comprising cabinet 51 is arranged, be rotatably installed with tooth thumb wheel 52 in the cabinet 51 relatively, the gear 53 of tooth thumb wheel 52 is connected for gear drive with gear shaft 7, the thumb wheel 54 of tooth thumb wheel 52 is connected with cam 55, and cam 55 is fixedly mounted on the bottom of tri-prismoid 3.

Gear shaft among the present invention adopts X alloy to make, tooth thumb wheel in the module assembly adopts plastic nylon to make, all elements in the cabinet almost do not have damage in 10 years, during the assembling of module assembly and lower frame, only need that module assembly is aimed at U type lower frame and press downwards and get final product.Changing original paper only needs taking off of damaging only needed one minute, need not to carry out the duplication of labour.

During machine operation among the present invention, the driven gear axle rotates, and the tooth thumb wheel in the gear shaft driver module assembly, the cam through module assembly inside turn to and drive tri-prismoid (picture) and rotate, and three faces of realizing turn over the dynamic effect of automatic upset.Gear shaft is fixedly mounted in the lower frame by bearing seat, and locating shaft is fixedly mounted in the upper side frame, can be apart from unanimity when making several arrangements of tri-prismoid.

Embodiment recited above is described preferred implementation of the present invention; be not that design of the present invention and scope are limited; under the prerequisite that does not break away from design concept of the present invention; common engineering technical personnel make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
