Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-6, the present invention provides a technical solution:
example 1:
as shown in fig. 1 and fig. 2, a specimen exhibition stand with lifting and rotating functions comprises a stand body 1 and a rotary lifting device 2 arranged in the stand body 1,
the rotary lifting device 2 comprises a driving motor 3, a lead screw 4, a display plate 5 matched with the lead screw 4, two limiting rods 6, a rotating disc 7 and a rotating cylinder 8, wherein the lead screw 4 is vertically arranged, and the bottom end of the lead screw 4 is connected with an output shaft of the driving motor 3; the display plate 5 is arranged on the screw rod 4, and two mounting holes for two limiting rods 6 to pass through are formed in the display plate 5; the two limiting rods 6 are respectively arranged in the two mounting holes, and the top ends of the two limiting rods 6 are respectively connected with the bottom surface of the rotating disc 7; a rotating hole is formed in the center of the rotating disc 7, one end of the rotating cylinder 8 is fixedly connected with the inner top surface of the exhibition cover 15 of the exhibition stand body 1, and the other end of the rotating cylinder 8 extends into the rotating hole; (wherein the limiting rod 6 and the mounting hole can slide relatively.)
And a locking mechanism 9 for limiting the relative rotation of the rotating disc 7 and the rotating cylinder 8 is arranged on the rotating cylinder 8.
The working principle is as follows: when the exhibition stand is in normal use, the locking mechanism 9 is not in action, namely, the rotating disc 7 can rotate relative to the rotating cylinder 8. At this moment, the driving motor 3 drives the screw rod 4 to rotate, the screw rod 4 drives the display board 5 on the screw rod to rotate, the specimen placed on the display board 5 rotates along with the screw rod, and then the function of specimen rotating display is realized.
When the height of the specimen needs to be raised or lowered, the rotating disc 7 and the rotating cylinder 8 are connected through the locking mechanism 9, at the moment, the rotating disc 7 cannot rotate relative to the rotating cylinder 8 due to the effect of the locking mechanism 9, and then the limiting rod 6 on the rotating disc 7 cannot rotate relatively. At the moment, the display board 5 moves along the axis of the screw rod 4 under the action of the screw rod 4 and the limiting rod 6, and the specific control of the rising or falling of the display board 5 is realized by controlling the positive and negative rotation of the driving motor 3. When the display board 5 ascends or descends, the specimen on the display board ascends or descends, and then the functions of specimen lifting display and height position adjustment are achieved. After the height adjustment is finished, the locking mechanism 9 is released, and the display board 5 rotates under the action of the driving motor 3.
The platform of the utility model has the functions of specimen rotary display and lifting adjustment, can display the specimen comprehensively, in multiple directions and at multiple angles, and has better observation effect; the lifting and rotating functions are realized by one motor, the structure is simple, the production cost is reduced, and the using effect is better.
Further, as shown in fig. 2, the locking mechanism 9 includes two power columns 10, two first return springs 11, two second return springs 12 and two locking columns 13, two connecting holes 14 for the power columns 10 to slide are provided on the extending cover 15, the power columns 10 are connected with the connecting holes 14 in a sliding fit manner, the top ends of the power columns 10 extend upward to extend out of the extending cover 15, the bottom ends of the power columns 10 are provided with first inclined planes, the first return springs 11 are sleeved outside the power columns 10, and two ends of the first return springs 11 are respectively fixedly connected with the power columns 10 and the extending cover 15;
the side wall of the rotating cylinder 8 is provided with two opposite sliding holes 16, the two locking columns 13 are respectively arranged in the sliding holes 16, and the ends, close to each other, of the two locking columns 13 are respectively provided with a second inclined surface matched with the first inclined surface; the second return spring 12 is sleeved outside the locking column 13, and two ends of the second return spring 12 are respectively fixedly connected with the locking column 13 and the hole wall of the sliding hole 16;
and two locking holes 17 corresponding to the two sliding holes 16 are formed in the rotating disc 7.
When the rotating disc 7 and the rotating hole need to be locked, the power column 10 is pressed downwards, and when the power column 10 descends, the first inclined surface at the lower end of the power column acts on the second inclined surface. The power column 10 continues to descend, the locking columns 13 move towards the two ends far away from each other under the action of the first inclined surface and the second inclined surface, and then extend into the locking holes 17 through the sliding holes 16, and at the moment, the relative rotation of the rotating disc 7 and the rotating cylinder 8 is limited by the locking columns 13. When the limitation needs to be removed, the power column 10 is released, the power column 10 and the locking column 13 are reset under the action of the first return spring 11 and the second return spring 12 respectively, and the limitation removal is completed at the moment.
Furthermore, the hole wall of the sliding hole 16 is provided with a sliding groove, and the locking column 13 is provided with a sliding block in sliding fit with the sliding groove. The purpose of setting up spout and slider is in order to guarantee that locking post 13 direction of motion is only and do not take place the upset, and then guarantees that first inclined plane and second inclined plane can correspond all the time. (not shown in the figure)
Further, the sliding groove is a T-shaped groove or a dovetail groove. So set up and can avoid the slider to break away from the spout, further guarantee the stability of locking post 13 motion.
