The following examples are given for the detailed implementation and specific operation of the present invention, but the scope of the present invention is not limited to the following examples.
As shown in fig. 1 and 2, an exhibition cabinet for entrepreneurship propaganda comprises a transparent cabinet body 10 and a box body 20 installed at the bottom in the cabinet body 10, wherein a circular exhibition stand 40 is arranged above the box body 20 in the cabinet body 10, the exhibition stand 40 comprises an outer ring 41, an inner disc 42 coaxially and rotatably arranged on the inner wall of the outer ring, and a positioning device 44 arranged on the inner disc 42, and the outer ring 41 is fixed on the inner wall of the cabinet body 10 through at least two symmetrical telescopic springs 43; the driving device 30 is installed in the box body 20, a driving end of the driving device 30 penetrates through the top of the box body 20 and is fixedly connected with one side of the bottom of the inner disc 42 and drives the inner disc 42 to rotate, and the driving end of the driving device 30 can be lifted to adjust the inner disc 42 to incline to the other side to realize angle adjustment.
The driving device 30 comprises a hydraulic cylinder 31 fixed at the bottom of the cabinet body 10 and a rotating motor 33 fixed on the telescopic end above the hydraulic cylinder 31; one side of the bottom of the inner disc 42 is connected to the driving end of the rotating motor 33 through a connecting portion 34, and the connecting portion 34 is non-linear.
The connecting portion 34 includes a first vertical portion 341 connected to a driving end of the rotating electrical machine 33, an inclined portion 342, and a second vertical portion 343 vertically fixed to one side of the bottom of the inner disc 42, the inclined portion 342 is connected between the first vertical portion 341 and the second vertical portion 343, the bottom of the rotating electrical machine 33 is further fixed with the fixing plate 32, and the fixing plate 32 is fixedly connected to the telescopic end of the hydraulic cylinder 31. Specifically, start rotating electrical machines 33, rotatory through connecting portion 34, connecting portion 34 drives inner disc 42 coaxial rotation in outer ring 41, if want to carry out the angular adjustment of stand, when the stand rotated to suitable angle, closed rotating electrical machines 33, start hydraulic cylinder 31, drive connecting portion 34 upwards jack-up or descend one side of inner disc 42 downwards for inner disc 42 inclines to the opposite side.
The first vertical portion 341, the inclined portion 342 and the second vertical portion 343 are integrally formed, and the structural stability of the entire connecting portion 34 is increased by the integral forming.
As shown in fig. 3, the extension spring 43 is fixed on the inner wall of the cabinet 10 by a fixing block 431; the inner wall of the outer ring 41 is provided with a sliding groove 411, the outer wall of the inner disc 42 is provided with a protrusion 422 corresponding to the sliding groove 411, and the inner disc 42 is clamped into the sliding groove 411 through the protrusion 422 and is slidably arranged in the outer ring 41. Since the extension spring 43 has a certain elastic space, the height of the inner tray inclined up and down is between the maximum extension length and the minimum compression length of the extension spring 43. In order to ensure the normal adjustment of the angle, the height of the first vertical portion 341 is not less than the up-down inclined height of the inner disc.
