Abstract
The utility model relates to a drive device used in advertising lamp box to conduct picture switch. The utility model comprises a lamp box frame, a picture board, and a baffle grid plate, which is characterized in that: the baffle grid plate is arranged on a slideway, the baffle grid plate has a drag rod, the top end of the drag rod has two upright posts, an eccentric cam hugs closely between two upright posts, in addition, the eccentric cam is connected with a motor fixed on the lamp box frame. The picture board has a drag rod, the picture board is arranged on the slideway, and the baffle grid plate is fixed on the lamp box frame. The upright posts of the drag rod are sheathed with a bearing at tangent places of the eccentric cam. The utility model has the advantages that the entire switch device can retain stable and continuous switching in the process of lamp box operation, simplifying the drive structure, as well as reducing the power of the drive motor.
Description
Technical field
The utility model relates to a kind of drive unit, and particularly a kind of advertising lamp box that is used for carries out the drive unit that picture switches.
Background technology
At present along with rapid economy development, advertisement also extend into every field, and owing to can arrange that in the zone, downtown area the position of advertisement is very limited, therefore in order in the finite space, only to increase clutter possibly, occurred to utilize mechanical hook-up in an advertising lamp box, to switch the advertising lamp box of several advertisement pictures, this kind advertising lamp box mainly is that the grid that blocks that utilizes a slice to be arranged on before the picture is selected picture point on the picture, if the picture of arranged alternate multi-picture point in order on picture, then block grid and just picture can be switched as long as move, in each demonstration, width of cloth during in the display frame several are drawn, existing switching-driving device is to adopt the drive unit of electronic circuit control driven by motor one nested structure complexity, and rely on numerous positioning limit switches to finish the switching of picture, because people's vision is very responsive, therefore work as the picture point relative position that blocks on grid and the picture deviation is arranged slightly, will produce the error of demonstration, influence the correct demonstration of picture, existing switching driving device is the course of work in an interrupted stage in each the switching simultaneously, in order just to need bigger power by the heavier grid that blocks of drive ratio, at the big noise of the generation in service of entire equipment, and whole lamp box is in order to hold switching driving device, the thickness of lamp box will strengthen, current driving mode has increased the manufacturing cost of product greatly in a word, has also reduced the reliability that product is in operation.
Summary of the invention
The purpose of this utility model is to solve in the prior art utilizing stepper motor to drive the screw mandrel rotation to block grid in to lamp box and drive the existing the problems referred to above of image switching, provide a kind of advertising lamp box that is used for to carry out the drive unit that picture switches.A kind of advertising lamp box that is used for of the utility model design carries out the drive unit that picture switches, comprise Lamp case frame, pictute plate, block flase floor, it is characterized in that: block flase floor and be arranged on the slideway, block flase floor one pull bar is arranged, two root posts are arranged on the top of pull bar, be glued with an offset cam in the middle of two root posts, offset cam has a motor that is fixed on the Lamp case frame to connect.Pull bar is arranged on the pictute plate, and pictute plate is arranged on the slideway, blocks flase floor and is fixed on the Lamp case frame.Column on the pull bar is being with bearing with the tangent place of offset cam.Described offset cam is oval.The edge of described offset cam is made of some groups of cambered surfaces, and every group of cambered surface is the cumulative cambered surface of one section radius and one section with cumulative radius is that the arc surface of radius is formed.The edge of described offset cam is made of some groups of cambered surfaces, every group of cambered surface be one section radius decrescence cambered surface and one section be that the arc surface of radius is formed with radius decrescence.The utility model has the advantages that can be in the operation process of lamp box, and whole switching device shifter held stationary switches continuously, has simplified drives structure, has reduced the power of drive motor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is the local plan structure synoptic diagram that amplifies of Figure 1A of the present utility model,
Embodiment
Comprise Lamp case frame 1, pictute plate 2 among the figure, block flase floor 3, it is characterized in that: block flase floor 3 and be arranged on the slideway 4, block flase floor 3 pull bar 5 is arranged, two root posts 6 are arranged on the top of pull bar 5, be glued with an offset cam 7 in the middle of two root posts 6, offset cam 7 has a motor shaft 8 that is fixed on the Lamp case frame 1 to connect.Also can fixedly block flase floor 3, and pull bar 5 is arranged on pictute plate 2, pictute plate 2 is arranged on the slideway 4.Column 6 on the pull bar 5 is being with bearing 9 with offset cam 7 tangent places.Described offset cam 7 is oval, and offset cam 7 also can be that the edge is made of some groups of cambered surfaces, and every group of cambered surface is the cumulative cambered surface of one section radius and one section with cumulative radius is that the arc surface of radius is formed.Offset cam 7 also can be that the edge is made of some groups of cambered surfaces, every group of cambered surface be one section radius decrescence cambered surface and one section be that the arc surface of radius is formed with radius decrescence.In concrete the use, can save electronic control circuit, remove positioning switch and limit switch, motor directly is set at rotation, when motor shaft 8 drives offset cam 7 rotations, during the convex surface of offset cam 7 in two edge columns, offset cam 7 promotes to move behind the column 6, and bearing holder (housing, cover) 9 can be reduced friction on column 6, rotation along with offset cam 7, blocking flase floor 3 slowly moves, in moving the picture on the pictute plate 2 being switched demonstration according to this, be the cumulative cambered surface of one section radius and one section with cumulative radius as offset cam 7 is that the arc surface of radius is formed, and then the cumulative cambered surface of radius will be blocked flase floor 3 and be promoted to show another width of cloth pictures, subsequently one section with radius decrescence be radius arc surface then offset cam 7 no longer promote to move behind the column 6, this picture can keep, and meets that picture is once switching after the cumulative cambered surface section of offset cam 7 radiuses again, and runs into offset cam 7 when oval, then in image switching, whole lamp box presents slowly at the conversion picture.
