[0029] The inside of the frame 2 is separated into a first cavity 22 and a second cavity 23 through a crossbar 21, and a writing board 3 is rotatably connected in each of the first cavity 22 and the second cavity 23. It should be noted that in the embodiment, the first cavity 22 and the second cavity 23 are both provided as rectangular cavities, so as to facilitate the placement of a rectangular writing board 3. After the frame 2 is rotated, horizontal and vertical statistical display of the rectangular writing board 3 can be realized, thereby improving the applicability of data writing and display. Of course, the provision of two writing boards 3 can also facilitate the comparison between different data, so as to further optimize the intuitive reference in the data statistical process.

[0030] The locking structure 4 is provided between the writing board 3 and the frame 2, a vertical rod 5 is fixedly installed above the base 1, and a rotating assembly 6 is provided between the vertical rod 5 and the crossbar 21.

[0031] As a preferred, in order to realize the convenient movement of the whole device, the bottom of the base 1 is provided with a roller 11 in the embodiment, and specifically, the roller 11 in the embodiment is provided in a matrix of four, so as to realize the stability support and convenient movement of the whole base 1 through the design of the four rollers 11.

[0032] In some embodiments, the locking structure 4 comprises at least one stop frame 41 rotatably connected to the side of the frame 2 through a pin shaft and a torsional spring. The torsional spring is used to realize the resetting ability of the stop frame 41 after rotation. As known by those skilled in the art, the two ends of the torsional spring can be connected to the frame 2 and the stop frame 41 respectively, and the specific connection mode is a conventional means for those skilled in the art, which will not be described here.

[0033] The stop frame 41 has a first arm 411 and a second arm 412 which stop at both sides of the writing board 3 respectively.

[0034] In particular, in use, the stop frame 41 is in the initial state, and the first arm 411 and the second arm 412 stop at both sides of the writing board 3 respectively, so that the writing board 3 is stopped and positioned, and the writing board 3 cannot rotate in this position, so as to achieve the purpose of stable display. Of course, the writing board 3 in the embodiment has a double-sided writable structure, and when it is necessary to switch the writing surface, the stop frame 41 is rotated, and the first arm 411 and the second arm 412 are separated from both sides of the writing board 3, so that the writing board 3 can be rotated and switched.

[0035] Further, the rotating assembly 6 in the embodiment comprises a U-shaped frame 61 which is rotationally connected with the vertical rod 5, and the back end of the horizontal rod 21 is fixedly provided with a shaft rod 62, and the shaft rod 62 is rotationally connected with the U-shaped frame 61.

[0036] On the basis of the above embodiment, two abutting rods 51 are further arranged at the lower side of the vertical rod 5 in the embodiment, and the two abutting rods 51 are used for abutting the long side rod and the short side rod of the frame 2 respectively, that is, two abutting rods 51 are used for abutting the two side rods of the frame 2 in the embodiment, and the design purpose is to abut and support the bottom of the frame 2 through the abutting rod 51 when the frame 2 rotates, so as to guarantee the horizontal display effect of the frame 2.

[0037] In a preferred embodiment, the inner side of the U-shaped frame 61 in the utility model is fixedly provided with a locking ring 63, and the inner side of the locking ring 63 is circumferentially provided with a plurality of clamping grooves 64.

[0038] The outer side of the shaft rod 62 is movably connected with a positioning bead 65, and the positioning bead 65 is clamped with the clamping groove 64. Of course, the outer side of the shaft rod 62 is provided with a through hole in the embodiment, and the positioning bead 65 is movably inserted into the through hole, and the diameter of the positioning bead 65 is greater than the inner diameter of the through hole, so as to avoid the positioning bead 65 from falling out of the through hole.

[0039] Specifically, in order to control the position of the positioning bead 65 and achieve the purpose of unlocking, the inner side of the shaft rod 62 is movably inserted with an unlocking rod 66 in the embodiment, and the end of the unlocking rod 66 is fixedly connected with a spring 67 between the inner hole of the shaft rod 62.

[0040] The unlocking rod 66 is provided with an inner recess 68, and the outer side of the positioning bead 65 is separated from the clamping groove 64 when the positioning bead 65 slides to the inner recess 68.

[0041] In summary, when the horizontal and vertical display switching of the two writing boards 3 is needed, the unlocking rod 66 is pressed first, and the unlocking rod 66 moves inward along the axial direction of the shaft 62 until the inner recess 68 and the positioning bead 65 are opposite, at this time, the positioning bead 65 moves along the arc surface of the inner recess 68 and is separated from the clamping groove 64 on the locking ring 63, in this state, the shaft 62 on the horizontal rod 21 and the U-shaped frame 61 are not locked, and the entire frame 2 can be rotated freely until the horizontal and vertical switching is completed, then the pressing on the unlocking rod 66 is released, at this time, the unlocking rod 66 moves outward, and the outer flat surface of the unlocking rod 66 pushes the positioning bead 65 outward to make the positioning bead 65 clamped into the clamping groove 64 to complete the position locking of the shaft 62;

[0042] Of course, when the writing surface of the writing board 3 needs to be switched, the entire frame 2 is rotated to the upper side through the rotation of the U-shaped frame 61 and the vertical rod 5 to avoid the interference of the vertical rod 5 to the rotation of the writing board 3, then the stop frame 41 is rotated, the first arm 411 and the second arm 412 are separated to the two sides of the writing board 3, and the writing board 3 can be rotated to change the surface.

[0043] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
