Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figs. 1-5, billboard connecting rod type transmission mechanism is turned on a kind of two sides, including prism 1, is connected to 1 lower end of prism
Crank 2 and be set to the lower section of prism 1 and by the perforative support frame 3 in the vertical portion of the crank 2,2 lower end of crank connects
Connecting rod 4 made of metallicl magnetic material are connected to, described 4 one end of connecting rod is connected with driving wheel 5, and the connecting rod 4, driving wheel 5 are equal
It is set to inside support frame 3, and on 3 inner wall of support frame of 4 two sides of the connecting rod, is additionally provided with magnet 6；The driving wheel 5
The internal diameter of diameter and the support frame 3 is adapted；The length of the lower end horizontal part of the L shape crank 2 and the driving wheel 5
Radius is equal；By magnet for the repulsion of metallicl magnetic material and the combination of attraction, so that connecting rod 4 is along transmission
Wheel 5 moves back and forth in support frame, and the movement of connecting rod 4 drives crank 2 to rotate, and the rotation of crank 2 drives prism 1 to rotate,
To realize the effect of turn-over, the running of transmission mechanism is effectively realized, solves existing motor-driven drive mechanism
The problem that system structure is complicated, components are more, effectively saves energy loss, reduces assembling and maintenance difficulties.
As second embodiment, on the basis of example 1, crank 2 and the connection type of connecting rod 4 are improved,
It is specific as follows:
Crank 2 is designed L-shaped, the upper end vertical portion of L shape crank 2 connects through 3 upside framework of support frame and prism 1
It connects, is fixedly installed detent block 21 on the downside of the end of the lower end horizontal part of L shape crank 2,21 lower end surface of detent block is provided with spiral shell
