[0028] See also Figure 1-6 , a disassembled data model for statistics, comprising a model base 1, a disassembled assembly structure 2 is arranged on the top of the model base 1;

[0029] The disassembly and assembly structure 2 includes a slot seat 201 opened on the top of the model base 1, a positioning platform 202 is clamped on the inner side of the slot seat 201, a worm 203 is internally rotatably connected to the positioning platform 202, a threaded screw 204 is internally rotatably connected to the positioning platform 202, a translation seat 205 is slidably connected to the top of the positioning platform 202, a tripod 206 is provided on the top of the translation seat 205, a model display board 207 is provided on the front of the tripod 206, and a positioning block 208 is magnetically connected to the front of the model display board 207.

[0030] Furthermore, the model base 1 is composed of a first base 101 and a second base 102 which are spliced ​​together. A protrusion structure is arranged on the right side of the first base 101, and a groove adapted to the protrusion is arranged on the left side of the second base 102. Pin hole grooves which are mutually penetrating structures are arranged inside the protrusion and the groove, and the internal threads of the two pin hole grooves are connected with a pin shaft rod 3.

[0031] Specifically, the protrusion structure on the right side of the first base 101 and the groove structure on the left side of the second base 102 are spliced ​​together, and then the pin shaft rod 3 is inserted into the pin hole groove that passes through the protrusion and the groove, so as to fix the first base 101 and the second base 102, and then assemble them into a model base 1.

[0032] Furthermore, a circular hole is provided on the inner bottom wall of the slot seat 201, and a magnet is fixedly installed inside the circular hole. The positioning platform 202 includes a foot seat 2021 which is clamped with the inner side of the slot seat 201, and a metal block with a cylindrical structure is fixedly connected to the bottom of the foot seat 2021. The metal block is plugged into the circular hole and is magnetically connected to the magnet. A pad 2022 is fixedly connected to the top of the foot seat 2021. There are two pads 2022, and a rotating shaft 4 is fixedly installed on the right side of one of the pads 2022, and the left side of the other pad 2022 is rotatably connected to the outer side of the rotating shaft 4.

[0033] Specifically, the foot 2021 of the positioning platform 202 is plugged into the circular hole on the inner side of the slot seat 201 through a metal block, and the slot seat 201 and the positioning platform 202 are assembled by magnetic attraction between the metal block and the magnet sheet. The left and right side pads 2022 are rotatably connected through the rotating shaft 4, thereby ensuring the rotation and folding effect of the side pads 2022.

[0034] Furthermore, a rotating wheel is coaxially fixed to the front end of the worm 203, one end of the threaded screw 204 is fixedly connected to the worm wheel 5, the outside of the worm 203 is meshed with the worm wheel 5, two slide grooves are provided on the top of the pad 2022, the bottom of the translation seat 205 is connected to the external thread of the threaded screw 204 through the slide groove, and a mounting groove is provided on the top of the translation seat 205, a plurality of screw hole structures are provided on the inner side of the mounting groove, and the support bracket 206 is clamped with the inner side of the mounting groove through a bolt structure.

[0035] Specifically, each pad 2022 is rotatably connected to two threaded screws 204. The rotating wheels on the two pads 2022 are rotated to drive the worm 203 respectively. The worm 203 is engaged with the worm wheel 5, so that the two threaded screws 204 in each pad 2022 rotate synchronously, and the threaded screw 204 is used to drive the translation seat 205 to move left and right.

[0036] Furthermore, there are two support legs 206, and a folding member 6 is provided on the opposite side of the two support legs 206. The folding member 6 includes bearing seats 601 movably installed on the opposite side of the two support legs 206, wherein the inner side of one of the bearing seats 601 is rotatably connected to two first connecting rods 602, and the inner side of the other bearing seat 601 is rotatably connected to two second connecting rods 603.

[0037] Specifically, first stretch the first connecting rod 602 and the second connecting rod 603 on both sides, adjust the expansion distance of the support frame 206 according to the distance between the two translation seats 205, then match the support frame 206 with the installation slot on the top of the translation seat 205, and use a bolt structure to clamp and fix the support frame 206 to the inner side of the installation slot.

[0038] Furthermore, the two second connecting rods 603 are fixedly connected with positioning ring pieces 604 at one end facing the two first connecting rods 602, and one end of the two first connecting rods 602 is rotatably connected to the two positioning ring pieces 604 respectively, and the two positioning ring pieces 604 are both hollow structures.

[0039] Specifically, when the first connecting rod 602 and the second connecting rod 603 are stretched or contracted, the upper and lower positions of the two positioning ring pieces 604 will change.

[0040] Furthermore, the model display panel 207 is a panel structure consisting of four panels hinged to each other, wherein a first positioning groove 7 is provided on the back of one of the panels, a plurality of equally spaced socket structures are provided on the inner side of the first positioning groove 7, and positioning rods 8 adapted to the sockets are inserted on the inner sides of the two positioning ring pieces 604.

[0041] Specifically, the four panels of the model display board 207 are spread out, and the screw holes on the two panels are fixed to the screw hole surfaces on the two support brackets 206 by screws. At this time, the first positioning groove 7 on the back of one of the panels is aligned with the two positioning ring pieces 604, and then the two positioning ring pieces 604 are inserted through the positioning rod 8 and fixed to the inner side of the first positioning groove 7, thereby limiting the expansion angle of the first connecting rod 602 and the second connecting rod 603, and preventing the two support brackets 206 from continuing to move after the distance between them is adjusted.

[0042] Furthermore, three second positioning grooves 9 are opened on the front of each panel and are evenly distributed. A magnetic strip is fixedly connected to the inner side of each second positioning groove 9. The positioning block 208 is an iron structure, and a rope 10 is tied to the outer side of the positioning block 208.

[0043] Specifically, one step of displaying statistical data is to draw a data change trend graph. By adjusting each positioning block 208 at different heights in the second positioning slot 9, the positioning block 208 is adsorbed and positioned with the magnetic strip, and the zigzag trend of the rope 10 is coordinated to display the data change trend.

[0044] In summary, the principle of using the separable data model for statistics is: docking the convex structure of the first base 101 with the concave structure of the second base 102, passing the pin shaft rod 3 through the pin hole grooves of the first base 101 and the second base 102, fixing the connection part of the first base 101 and the second base 102, so as to splice and form the model base 1, and the reverse order can be used to disassemble the model base 1;

[0045] The foot 2021 of the positioning platform 202 is clamped on the inner side of the groove seat 201 through the magnetic attraction effect of the metal block and the magnet sheet, and the positioning platform 202 and the model base 1 are assembled. Then the worm 203 is rotated, and the worm gear 5 structure on the threaded screw 204 is engaged by the worm 203. The threaded screw 204 is used to drive the translation seat 205 to move left and right to adapt to the distance between the two supporting legs 206. Then, the supporting legs 206 are installed with the mounting groove on the top of the translation seat 205 through the bolt structure. When disassembling the branching legs 206 and the positioning platform 202, the operation can be performed in the opposite order.

[0046] Then stretch the first connecting rod 602 and the second connecting rod 603 between the supporting legs 206 to expand them, fix the two panels on the model display board 207 to the two supporting legs 206 respectively through the screw structure, and then insert the positioning rod 8 into the two positioning ring pieces 604 to fix the expanded position of the first connecting rod 602 and the second connecting rod 603 to the inner side of the first positioning groove 7, so as to prevent the problem that the position of the supporting legs 206 continues to change due to the influence of the connecting rods on both sides after being fixed. When disassembling the branching legs 206 and the model display board 207, the operations can be carried out in the reverse order.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
