The first spring telescopic column 9 is installed on both sides of the upper end of the front surface of the metal display board 3, and the front side of the metal display board 3 is provided with a hoisting platform 10 There are fixed bearings 11 installed on both sides of the inner surface of the Yi-shaped lifting platform 10, and a rotating shaft 12 is provided on one side of the fixed bearing 11. One end of the rotating shaft 12 is inserted into the fixed bearing 11, and a second spring telescopic column 13 is installed on the outer surface of the rotating shaft 12. , transmission gear 14 is installed on the rotating shaft 12, rack 15 is installed on the two ends of the front side surface of metal display board 3, transmission gear 14 and rack 15 are meshed with each other, and the problem that it mainly solves is: when calligraphy shaft 40 is hung up Afterwards, the calligraphy shaft 40 is fixed by the first spring telescopic column 9 and the second spring telescopic column 13, and the rotating motor 21 is started to rotate, and the rotating screw rod 22 drives the U-shaped lifting platform 10 to lift, and the connection between the tooth bar 15 and the transmission gear 14 Mesh, rotate and open the calligraphy shaft 40, the calligraphy shaft can be opened automatically by wireless and manual, easy to use, and this device completes multiple tasks through a rotating motor 21, saving electric energy,

The invention of the present application also lies in the structural design of the fixing mechanism. In this device, in conjunction with accompanying drawing 4, the fixing mechanism includes multiple groups of connecting columns 27 fixedly installed on both ends of the front side surface of the support platform 2, and each group of connecting columns 27 is provided with two and are respectively located on both sides of the metal display board 3, a connecting ring 28 is installed on the front side surface of the connecting column 27, an elastic rope 29 is connected between the two connecting rings 28, and a tapered stopper 30 is installed on the outer surface of the Yi-shaped lifting platform 10. , the outer surface of the tapered block 30 has a plurality of square grooves 31, and the support wheels 32 are installed in the square grooves 31. The main problem to be solved is: after the calligraphy shaft 40 is opened, in order to prevent the calligraphy shaft 40 from shaking, It needs to be fixed. When the U-shaped lifting platform 10 moves, the elastic rope 29 is first propped up by the tapered stopper 30, and the elastic rope 29 is transferred to the other side of the U-shaped lifting platform 10, and the calligraphy shaft 40 is fixed.

This application is also provided with a moving mechanism, a holding mechanism, and a control mechanism. When in use, the position of the device can be adjusted through the universal wheels 33 and the pushing handrails 35 in the moving mechanism, which is convenient for calligraphy observation. The correspondence between the information label 44 and the identification plate 42 is convenient to find the corresponding calligraphy axis, and can be picked and placed quickly. The device can be remotely controlled to start by the remote controller 47 in the control mechanism, which is easy to use. The specific working steps are as follows:

The first step, placement: move the device to a suitable position by pushing the armrest 35 and the universal wheel 33, lock the brake pad 34, fix the device, and find the corresponding calligraphy axis that needs to be observed according to the information label 44 40, and take it out, when putting it back, you can quickly locate the calligraphy shaft 40 by the corresponding label on the identification plate 42, and put it back to its original position, after the calligraphy shaft 40 is taken out, hang the suspension line 41 On the hook 7, the shaft at the upper and lower ends of the calligraphy shaft 40 is respectively placed between the first spring telescopic post 9 and the second spring telescopic post 13, and the calligraphy shaft is passed through the first spring telescopic post 9 and the second spring telescopic post 13. 40 is fixedly placed. In the process, this device can quickly find and place the corresponding calligraphy axis 40, and the position can be adjusted to facilitate better observation of calligraphy.

The second step, opening and closing: the user stands at a distance, uses the remote controller 47 to issue instructions, and the controller 46 controls and starts the rotating motor 21 to rotate, and the rotating screw 22 below it is driven by the coupling 25 on the rotating motor 21 Rotate, and make transmission wheel 23 rotate, carry out transmission by transmission belt 24, make another transmission wheel 23 rotate, thereby make two rotating screw rods 22 rotate in the same direction between screw rod bearings 17, pass threaded hole 26 and rotating screw rod 22 The threaded connection drives the U-shaped elevating platform 10 to move downwards. Since the transmission gear 14 is meshed with the rack 15, the rotating shaft 12 is driven to rotate in the fixed bearing 11, so that the second spring telescopic column 13 rotates accordingly, and in the 匚When shaped lifting platform 10 descends, drive calligraphy shaft 40 lower ends to rotate and calligraphy shaft 40 is opened, and when opening, because calligraphy shaft 40 just begins outer diameter big, when rotating shaft 12 rotates one week, the calligraphy shaft 40 rotates out There are many paper surfaces, and the calligraphy shaft 40 is temporarily in a loose state. With the opening of the calligraphy shaft 40, its outer diameter gradually decreases. When the shape lifting platform 10 descended to the lowest point, the calligraphy shaft 40 was just fully opened, and the relatively tight state was taken out. When the calligraphy shaft 40 was opened, the hook 7 stretched the telescopic spring 8 and moved. When the calligraphy shaft 40 was opened, along with Tensile force moves, prevents calligraphy shaft 40 from being torn apart, and after observation is finished, start rotating motor 21 to reverse, and drive 匚-shaped lifting platform 10 to rise, thereby make rotation shaft 12 reverse, and calligraphy shaft 40 is packed up, here During the process, this device can automatically open or close the calligraphy shaft 40 by changing the rotation direction of the rotating motor 21, which is more convenient to use.

The third step, fixing: when the 匚-shaped lifting platform 10 rises or falls, contact the elastic cord 29 through the tapered stopper 30, prop up the elastic cord 29 to the outside, and pass the rotation of the support wheel 32 to facilitate the elastic cord 29 Through, after this elastic cord 29 passes through first tapered stopper 30, another tapered stopper 30 slowly puts down the propped up elastic cord 29, and the open position of calligraphy shaft 40 is fixed, in this process In this way, it is convenient to fix the calligraphy axis 40 to prevent shaking and avoid damage to the calligraphy axis 40 .

The above-mentioned technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention, and some changes that those skilled in the art may make to certain parts reflect the principles of the present invention and fall within the protection scope of the present invention.
