Description

exhibition display device

Technical Field

The invention relates to the technical field of machinery, in particular to an exhibition display device.

Background

The exhibition display device structure sheet of the prior art is common in style, difficult to attract the eyes of customers and needs improvement.

Disclosure of Invention

The invention aims to provide exhibition display devices to solve the problems that the exhibition display device in the prior art is simple in structure , common in style and difficult to attract the eyes of customers.

In order to solve the above technical problems, an embodiment of the present invention provides exhibition display devices, including a disk, a driving shaft is disposed in the center of the disk, a support is disposed on the driving shaft, six support arms are uniformly distributed on the support along the circumferential direction, the six support arms are equal in length, a slide rail is disposed at an eccentric position on the disk, six slide blocks are disposed on the slide rail, a crank is rotatably disposed at an outer end of each support arm, an outer end of each crank is rotatably disposed on a slide block through a rotating shaft, a display board is vertically disposed on the rotating center of the crank, the six display boards are disposed in parallel, an eccentric distance between the slide rail and the disk is equal to the length of the crank, two adjacent display boards form pairs and are provided with stabilizer bars, a connecting line of centers of the cranks corresponding to the two adjacent display boards is set as a crank connecting line, the stabilizer bars are parallel to the crank and are not coincident.

And lightening holes are formed in the disc and used for balancing the balance weight of the eccentric sliding rail.

The drive shaft is driven by motor to rotate the bracket.

The technical scheme of the invention has the following beneficial effects:

when the drive rod rotates, the exhibition display device of the invention always keeps directions of the display boards, and six display boards can temporarily hold the same things or different things, so the exhibition display device has novel structural design, can attract the eyeballs of customers and has practicability.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 4, an embodiment of the invention provides exhibition display devices, which include a disc 1, a driving shaft 2 is disposed in the center of the disc 1, a support frame 3 is disposed on the driving shaft 2, six support arms 4 are uniformly distributed on the support frame 3 along the circumferential direction, the six support arms 4 are equal in length, a sliding rail 5 is disposed at an eccentric position on the disc 1, six sliding blocks 6 are disposed on the sliding rail 5, an outer end portion of each support arm 4 is rotatably disposed with a crank 7, an outer end of each crank 7 is rotatably disposed on a sliding block 6 through a rotating shaft 8, a display plate 9 is vertically disposed upward from a rotation center of the crank 7, the crank 7 is fixed to the display plate 9, the six display plates 9 are disposed in parallel, a distance between the sliding rail 5 and the disc 1 is equal to a length of the stabilizing rod 7, two adjacent crank display plates 9 form a pair of the stabilizing rod and are provided with , a connecting line between centers of the cranks corresponding to the two adjacent display plates 9 is crank connecting lines, the stabilizing rod 10 is parallel to the crank connecting lines and is not overlapped in the vertical direction, a length of.

The disc 1 is provided with lightening holes 11, and the lightening holes 11 are used for balancing the balance weight of the eccentric slide rail, so that the center of gravity of the whole display device is distributed on the axis of the driving shaft.

The driving shaft 2 is driven by motor (not shown) to rotate the bracket 3.

When the driving shaft rotates to drive the support and the support arm to rotate, the display board connected with the crank always keeps in directions, the crank, the support arm, the sliding block and the sliding rail form a parallelogram mechanism, and the stabilizer bar is arranged to increase the stability of the crank and the sliding block in the movement process and overcome the dead point position of the mechanism.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.

Claims

The exhibition display device of kinds, a serial communication port, including the disc, the disc center is equipped with the drive shaft, be equipped with the support in the drive shaft, the support has six support arms along circumference equipartition, six support arms are isometric, eccentric department is equipped with the slide rail on the disc, be equipped with six sliders on the slide rail, every the outer tip rotation of support arm is equipped with crank, every on slider is located through the pivot rotation in articulate outer end, the vertical upwards of articulate rotation center is equipped with the show board, six show board parallel arrangement, the eccentric distance of slide rail and disc equals articulate length, and two adjacent show boards become pairs and are equipped with stabilizer bars, and the line at the crank center that two adjacent show boards correspond is established to crank line, parallel and the vertical direction nonconformity with the stabilizer bar line, the length of support arm equals the radius of slide rail.
2. The exhibitions display device of claim 1, wherein said disk is provided with lightening holes for balancing the counterweights of the eccentric slide rails.
