The device can be installed according to Fig. 9 In the manner described above, multiple outer frames 4 are connected end to end through the first connecting component 7 and the second connecting component 8 to form a surrounding structure to adapt to different usage scenarios for displaying financial data information.

[0035] In this embodiment, the connecting plate 2 and the movable frame 1 are rotatably connected, and the fixed shafts 3 are symmetrically distributed on both sides of the connecting plate 2. The outer wall of the fixed shaft 3 and the inner wall of the through hole 5 are in contact with each other. The rotatably installed connecting plate 2 is convenient for subsequent folding and storage, and the fixed shaft 3 can be inserted into the through hole 5 so as to support and use the entire device.

[0036] In this embodiment, the through holes 5 are arranged on both sides of the diagonal corners of the outer frame 4. The positions and number of the through holes 5 correspond to the positions and number of the fixed shafts 3. The two through holes 5 distributed at the diagonal positions of the outer frame 4 can be arranged according to Figure 1 In this way, the screen is stored in the device after being kept in a relative position, and finally the fixed shaft 3 is inserted into the through hole 5, making the device easier to carry.

[0037] In this embodiment, the first connecting component 7 includes a first outer bushing 701 fixedly connected to the left side and upper side of the outer frame 4, a first connecting shaft 702 is slidably installed in the first outer bushing 701, a docking block 703 is fixedly provided on the first connecting shaft 702, a first connecting ring 704 is welded on the first outer bushing 701, and the first outer bushing 701 allows the first connecting shaft 702 to slide so that the left side of the subsequent outer frame 4 can be docked with the remaining outer frames 4, and the docking position can be adjusted as needed.

[0038] In this embodiment, the first outer bushings 701 are evenly spaced on the outer frame 4, and a first spring 705 is fixedly connected between the middle first outer bushing 701 and the first connecting shaft 702. The first spring 705 enables the left side of the outer frame 4 to remain in a tensioned state when docking with the adjacent outer frame 4, thereby enhancing the overall stability of the device.

[0039] In this embodiment, the second connecting component 8 includes a second outer sleeve 801 fixedly connected to the right side and lower side of the outer frame 4, a second connecting shaft 802 is slidably installed in the second outer sleeve 801, and the second connecting shaft 802 is provided with a mounting groove 803 for docking with the docking block 703. A second connecting ring 804 is fixedly connected to the second outer sleeve 801, and the second connecting shaft 802 can slide inside the second outer sleeve 801, so as to facilitate the subsequent docking of the right side of the outer frame 4 with the left side of the adjacent outer frame 4.

[0040] In this embodiment, the second outer bushings 801 are evenly spaced on the outer frame 4, and a second spring 805 is fixedly connected between the second outer bushing 801 in the middle position and the second connecting shaft 802. The second spring 805 keeps the right side of the outer frame 4 in a tensioned state after docking, and facilitates the subsequent automatic resetting of the second connecting shaft 802.

[0041] In this embodiment, the inner wall of the mounting groove 803 and the outer wall of the docking block 703 are in contact with each other. The docking block 703 is in the shape of a spherical segment. The docking block 703, the first connecting shaft 702 and the second connecting shaft 802 are all made of rubber. The first connecting shaft 702 forms a snap-fit ​​structure through the docking block 703 and the mounting groove 803 and the second connecting shaft 802. Through the snap-fit ​​structure on the device, after the docking block 703 is docked with the mounting groove 803, the first connecting shaft 702 and the second connecting shaft 802 maintain a flexible snap-fit ​​state. The docking block 703 made of rubber can be detached after the tension between the first connecting shaft 702 and the second connecting shaft 802 reaches a certain level, thereby conveniently switching the display mode of the display device.

[0042] In this embodiment, the connecting grooves 10 are evenly spaced on the heat dissipation shell 6, and the periphery of the heat dissipation shell 6 is a mesh structure. When the device is in the air-cooling process, after the cold air blows into the connecting grooves 10 of the heat dissipation shell 6, the gas carrying the heat can be discharged by the mesh structure on the periphery of the heat dissipation shell 6, thereby allowing the device to form a heat dissipation duct while ensuring the heat dissipation effect.

[0043] In this embodiment, the diameter of the third outer bushing 16 decreases from top to bottom, the third outer bushing 16 forms a rotating structure with the screw 14 through the convex ring 20, the third outer bushing 16 and the slider 17 abut against each other, the slider 17 forms a sliding structure with the screw 14 and the third outer bushing 16 and the docking rod 11, the first connecting ring 704 and the second connecting ring 804 are both provided with a first convex pattern 21 on the inner side, the slider 17 is provided with a second convex pattern 22 on the outer side, the position of the slider 17 corresponds to the position of the first connecting ring 704 and the second connecting ring 804, the slider 17 is made of rubber, and when the device rotates the screw 14, such as Figure 8 As shown, when the screw 14 is screwed downward, it drives the third outer bushing 16 to move downward through the convex ring 20. The outer wall of the third outer bushing 16 can push the slider 17 to the outside of the device. The second convex groove 22 on the outer side of the slider 17 can press against the first convex groove 21 on the inner wall of the first connecting shaft 702 and the second connecting shaft 802, so that the slider 17 and the first connecting shaft 702 and the second connecting shaft 802 are kept in a tightened state, so that the device can keep the angle between the two adjacent screens unchanged after adjusting the angle.

[0044] It should be noted that the present invention is a portable financial data analysis and display device. First, Figure 1-Figure 5 As shown, the mobile frame 1 and the connecting plate 2 on the device are used to support four outer frames 4. When in use, the four outer frames 4 can be taken out from the fixed shaft 3, and the through hole 5 is used to connect the fixed shaft 3 with the outer frame 4. Figure 4 and Figure 5 In the manner described above, the four outer frames 4 are connected horizontally and vertically by the first connecting component 7 and the second connecting component 8. When connecting, as shown in FIG. Figure 3-Figure 7As shown, the docking block 703 on the first connecting shaft 702 and the mounting groove 803 on the second connecting shaft 802 are docked. Since the docking block 703 is made of rubber and is a spherical segment structure, after the docking block 703 is completely installed in the mounting groove 803, the first connecting shaft 702 and the second connecting shaft 802 maintain a flexible engagement state. Since the first connecting shaft 702 and the second connecting shaft 802 are made of rubber, the first connecting shaft 702 and the second connecting shaft 802 on the first connecting component 7 and the second connecting component 8 between the two adjacent outer frames 4 can be bent, and the first spring 705 and the second spring 805 will be compressed, so that a certain angle is formed between the two adjacent outer frames 4, so that the device can adjust the angles between multiple outer frames 4 and the display screen 9 to adapt to different display needs. The first spring 705 and the second spring 805 facilitate the subsequent resetting of the first connecting shaft 702 and the second connecting shaft 802.

[0045] like Figure 2-Figure 5 , Figure 8 and Fig. 9 As shown, after the device has adjusted the display mode, the adjacent outer frame 4 is fixed, as shown in FIG. Figure 8 As shown, the second connection block 15 is rotated to drive the screw rod 14 to screw into the first connection block 13. When the screw rod 14 is screwed downward, it will drive the third outer bushing 16 to move downward through the convex ring 20. Since the diameter of the third outer bushing 16 decreases from top to bottom, the outer wall of the third outer bushing 16 can gradually push the slider 17 to the outside of the docking rod 11, and the slider 17 slides on the docking rod 11 through the slide groove 18 and the convex rod 19. The second convex pattern 22 on the outer side of the slider 17 can press against the first convex pattern 21 on the inner wall of the first connecting shaft 702 and the second connecting shaft 802, so that the slider 17 and the first connecting shaft 702 and the second connecting shaft 802 are kept in a tightened state, so that the device can keep the angle unchanged after adjusting the angle between the two adjacent screens. Fig. 9 In the manner described above, multiple display screens 9 and outer frames 4 are spliced ​​into a surrounding structure to realize the surrounding display of financial data information. When cooling the display screen 9, cold air is blown into the connecting groove 10 of the heat dissipation shell 6 by an external fan, and the mesh structure outside the heat dissipation shell 6 discharges the gas carrying heat, thereby forming a heat dissipation air duct.

[0046] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
