[0023] Reference Figure 1-4 A hanging chart device comprises a movable base 1, an adjusting component 2 is arranged on the top of the movable base 1, the adjusting component 2 comprises a shaft sleeve 21, a suspension component 3 is movably installed on the top of the shaft sleeve 21, the suspension component 3 comprises a movable shaft 32 rotatably installed on the top of the shaft sleeve 21, two hanging plates 31 are symmetrically connected on both sides of the movable shaft 32, a plurality of clamping components 36 are inserted in the guide groove at the bottom end of the hanging plate 31, the clamping component 36 comprises a slider 361, a fixing plate 363 is connected to the bottom end of the slider 361, and a U-shaped plate 364 is inserted through the through groove on the top side of the fixing plate 363, a clamping plate 366 is connected to the end of the U-shaped plate 364, a reset spring 365 is connected to the bottom end of the U-shaped plate 364, and the end of the reset spring 365 is connected and fixed to the fixing plate 363.

[0024] Two pulleys 362 are symmetrically mounted on the left and right sides of the bottom of the slider 361 , and the pulleys 362 abut against the inner wall of the guide groove of the hanging plate 31 .

[0025] Insertion plates 35 are inserted on the left and right sides of the hanging plate 31 , and arc grooves are formed on both sides of the insertion plates 35 .

[0026] A connecting plate 33 is connected to the center of the bottom end of one of the hanging plates 31 , and a threaded pin 34 is inserted into the front side of the connecting plate 33 through a threaded hole, and the end of the threaded pin 34 is inserted into the surface of the sleeve 21 through a positioning groove.

[0027] A vertical shaft 22 is inserted into the bottom end of the shaft sleeve 21 through a through slot, and the bottom end of the vertical shaft 22 is connected and fixed to the movable base 1 .

[0028] An insertion shaft 24 is inserted through a through hole on the bottom side of the sleeve 21, and a clamping block 23 is connected to the left side of the insertion shaft 24. The clamping block 23 is inserted into the side of the vertical shaft 22 through a clamping groove. A connecting plate 25 is connected to the right side of the insertion shaft 24, and a support spring 26 is sleeved on the surface of the insertion shaft 24.

[0029] The top of the clamping block 23 is designed as an arc structure, and the inner wall of the shaft sleeve 21 is provided with a movable groove adapted to the clamping block 23 .

[0030] The guide groove design of the hanging plate 31 can facilitate the installation of the slider 361 on the hanging plate 31. When the slider 361 moves, it can drive the pulley 362 to rub and roll on the inner wall of the guide groove of the hanging plate 31 to ensure the smoothness of the movement of the slider 361. The plug plate 35 is buckled on both sides of the hanging plate 31 to quickly close the guide groove of the hanging plate 31. At the same time, the arc-shaped groove design of the plug plate 35 can facilitate the gripping and plugging of the plug plate 35. When the hanging plate 31 is rotated and placed horizontally on the top of the shaft sleeve 21, the threaded pin 34 can be rotated and moved in the threaded hole of the connecting plate 33, and the threaded pin 34 can be controlled to be inserted in the positioning groove of the shaft sleeve 21 to ensure the stability of the hanging plate 31 placed horizontally on the top of the shaft sleeve 21. The shaft sleeve 21 moves on the surface of the vertical shaft 22, which can facilitate the shaft sleeve 2 1 is lifted and lowered to meet the size requirements of the economic trend chart. When the shaft sleeve 21 is pulled up, the shaft sleeve 21 can drive the block 23 to move, so that the arc surface of the block 23 is forced to move outward in the slot of the vertical shaft 22, ensuring the convenience of the shaft sleeve 21 on the surface of the vertical shaft 22. When the shaft sleeve 21 moves up to a suitable position, the rebound force of the support spring 26 can drive the connecting plate 25 to move, so that the connecting plate 25 pushes the plug shaft 24 to control the block 23 to be inserted into the slot of the vertical shaft 22, ensuring the stability of the shaft sleeve 21 after adjustment. The curved arc structure design of the block 23 can facilitate the block 23 to move out of the slot of the vertical shaft 22. The movable groove design on the inner wall of the shaft sleeve 21 can facilitate the block 23 to move and be embedded in the movable groove of the shaft sleeve 21.

[0031] Working principle: According to the attached Figure 3 With attached Figure 4As shown, during use, the slider 361 can be slid in from one side of the hanging plate 31 so that the slider 361 is inserted into the slide groove of the hanging plate 31. At this time, the installation can be completed by buckling the plug plate 35 on the side of the hanging plate 31, and the economic trend chart is placed between the fixed plate 363 and the clamping plate 366. The elastic force of the reset spring 365 pushes the U-shaped plate 364 so that the U-shaped plate 364 can move in the through groove of the fixed plate 363. The movement of the U-shaped plate 364 can drive the clamping plate 366 to move, thereby facilitating the clamping and hanging of the economic trend chart.

[0032] Secondly, according to the attached Figure 1 With attached Figure 2 As shown, when displaying a larger-sized economic trend chart, the side of the sleeve 21 can be held and lifted up, and the force at the bottom end of the slot of the sleeve 21 can squeeze the block 23, so that the block 23 is forced to push the plug shaft 24 to move, and the plug shaft 24 can drive the connecting disk 25 to move, and then stretch the support spring 26 to deform. When the sleeve 21 is raised to a suitable height, the elastic force of the support spring 26 can push the connecting disk 25 to move, and the connecting disk 25 can cooperate with the plug shaft 24 to push the block 23 to be inserted into the slot of the vertical shaft 22, and then the sleeve 21 can be self-locking and fixed.
