[0025] Please see Figure 1-3 The present invention provides a connection mechanism 98, which includes a first fixing frame 30, a second fixing frame 40 and a connecting member 50. The first fixing frame 30 and the second fixing frame 40 are slidably connected to two sides of the connecting member 50, respectively.

[0026] The connecting member 50 includes a first connecting section 51, a second connecting section 53 and a third connecting section 52 which are arranged in a straight line and connected end to end in sequence. The first connecting section 51 and the third connecting section 52 are respectively pivoted at the two ends of the second connecting section 53. Specifically, the two ends of the second connecting section 53 are respectively provided with a first pivoting portion and a second pivoting portion. An end of the first connecting section 51 close to the second connecting section 53 is pivoted to the first pivoting portion, and an end of the third connecting section 52 close to the second connecting section 53 is pivoted to the second pivoting portion. The first connecting section 51 and the third connecting section 52 can be rotated relative to the second connecting section 53 so that the first connecting section 51 and the third connecting section 52 are in a folded state or in a flat state. Specifically, when the first connecting section 51 and the third connecting section 52 are in a folded state, the first connecting section 51 and the third connecting section 52 are respectively rotated around the first pivoting portion and the second pivoting portion to the same side of the second connecting section 53, and the first connecting section 51 and the third connecting section 52 are oppositely and symmetrically arranged at the two ends of the second connecting section 53. When the first connecting section 51 and the third connecting section 52 are in a flat state, the first connecting section 51 and the third connecting section 52 rotate around the first pivot portion and the second pivot portion respectively until they are on the same straight line as the second connecting section 53. The rotation angle range of the first connecting section 51 and the third connecting section 52 relative to the second connecting section 53 is 0-95°.

[0027] Please see Figure 5 and 6The first connecting section 51 is in the shape of a rod. The first connecting section 51 includes a top wall 502 and a side wall 501 enclosed by the top wall 502. The top wall 502 has a first limiting surface on the side facing the first fixing frame 30. The first limiting surface is partially arched toward the first fixing frame 30 along the length direction to form an arched portion 5021. The corresponding position of the first fixing frame 30 has an adaptive second limiting surface. The first limiting surface and the second limiting surface are slidably fitted to limit the first connecting section 51 from rotating relative to the first fixing frame 30. The side wall 501 includes an arched first side wall 5011, two plane second side walls 5012 connected to both sides of the first side wall 5011, and the two ends of the top wall 502 are connected to the two second side walls 5012. The shape of the first through hole 32 is adapted to the first connecting section 51. The structure of the third connecting section 52 is substantially the same as that of the first connecting section 51, which will not be described in detail. A positioning member 531 is provided on the second connecting section 53. Specifically, the positioning member 531 is formed by protruding outward from the outer wall of the second connecting section 53. The positioning member 531 is arranged at the middle position of the second connecting section 53. The second positioning portion 511 and the third positioning portion 512 are arranged at intervals on the first connecting section 51. In the present embodiment, two positions spaced apart on the outer wall of the first connecting section 51 are respectively recessed inwards to form the second positioning portion 511 and the third positioning portion 512. The third positioning portion 512 is closer to the second connecting section 53 than the second positioning portion 511. The fifth positioning portion 521 and the sixth positioning portion 522 are arranged at intervals on the third connecting section 52. In the present embodiment, two positions spaced apart on the outer wall of the third connecting section 52 are respectively recessed inwards to form the fifth positioning portion 521 and the sixth positioning portion 522. The sixth positioning portion 522 is closer to the second connecting section 53 than the fifth positioning portion 521.

[0028] Please see Figure 4 The first fixing frame 30 includes a first fixing plate 31, a first protruding portion 34 protruding toward the back of the first fixing plate 31 along the width direction of the first fixing plate 31, and a first through hole 32 is provided in the first protruding portion 34. The first through hole 32 is used to accommodate the connecting member 50 and provide a movable space for the sliding of the connecting member 50. The first fixing frame 30 protrudes toward the first through hole 32 along the inner wall of the first through hole 32 to form a first positioning portion 321 that is limitedly matched with the second positioning portion 511 and the third positioning portion 512. The material of the first positioning portion 321 is plastic.

[0029] The second fixing frame 40 includes a second fixing plate 41, a second protruding portion 44 protruding toward the back of the second fixing plate 41 along the width direction of the second fixing plate 41, and a second through hole 42 is provided in the second protruding portion 44. The second through hole 42 is used to accommodate the connecting member 50 and provide a movable space for the sliding of the connecting member 50. The second fixing frame 40 protrudes toward the second through hole 42 along the inner wall of the second through hole 42 to form a fourth positioning portion 421. The material of the fourth positioning portion 421 is plastic.

[0030] When the first fixing frame 30 and the second fixing frame 40 are spliced ​​together (see Figure 1 ), the first positioning portion 321 of the first fixing frame 30 is limitedly matched with the third positioning portion 512 of the first connecting section 51, and the fourth positioning portion 421 of the second fixing frame 40 is limitedly matched with the sixth positioning portion 522 of the third connecting section 52, so that the first fixing frame 30 and the second fixing frame 40 are fixed relative to the first connecting section 51 and the third connecting section 52, respectively. Specifically, since the material of the first positioning portion 321 and the fourth positioning portion 421 is plastic, the first positioning portion 321 and the fourth positioning portion 421 are respectively released from the limited matching of the third positioning portion 512 and the sixth positioning portion 522 when they are in the assembled state; when the first positioning portion 321 and the fourth positioning portion 421 and the connecting member 50 are not in the assembled state, they are squeezed by the third positioning portion 512 of the first connecting section 51 and are in a static friction state with the connecting member 50.

[0031] The first fixing frame 30 and the second fixing frame 40 can slide in opposite directions along the connecting member 50 to be separated by a preset distance (see FIG. Figure 2 ), the first positioning portion 321 of the first fixing frame 30 is limitedly matched with the second positioning portion 511 of the first connecting section 51, and the fourth positioning portion 421 of the second fixing frame 40 is limitedly matched with the fifth positioning portion 521 of the third connecting section 52, so that the first fixing frame 30 and the second fixing frame 40 are fixed relative to the first connecting section 51 and the third connecting section 52 respectively. It is also convenient for the first fixing frame 30 and the second fixing frame 40 to rotate relative to the second connecting section 53 so that the first connecting section 51 and the third connecting section 52 are in a folded state (see Figure 3 ).

[0032] When the first fixing frame 30 and the second fixing frame 40 are folded in half, part of the first connecting section 51 and part of the third connecting section 52 are respectively received in the first through hole 32 and the second through hole 42. When the first fixing frame 30 and the second fixing frame 40 are in a spliced ​​state, the first connecting section 51 and the third connecting section 52 are respectively completely received in the first through hole 32 and the second through hole 42, and half of the second connecting section 53 along the length direction is received in the first through hole 32, and the other half along the length direction is received in the second through hole 42.

[0033] The first fixing frame 30 is slidably connected to the connecting member 50 from the first connecting section 51, and the second fixing frame 40 is slidably connected to the connecting member 50 from the third connecting section 52. Specifically, the first fixing frame 30 can slide from the first connecting section 51 to the second connecting section 53, and the second fixing frame 40 can slide from the third connecting section 52 to the second connecting section 53, and the travel of the first fixing frame 30 and the second fixing frame 40 is limited by the positioning member 531. When the first fixing frame 30 slides from the first connecting section 51 to the middle position of the second connecting section 53 and the second fixing frame 40 slides from the third connecting section 52 to the middle position of the second connecting section 53, the positioning member 531 is used to prevent the first fixing frame 30 and the second fixing frame 40 from continuing to slide in a direction approaching each other. At this time, the first fixing frame 30 and the second fixing frame 40 are in a state of being spliced ​​together (please refer to Figure 1 ).

[0034] When the first fixing frame 30 and the second fixing frame 40 receive a large external force and move in a direction away from each other so that the first positioning portion 321 of the first fixing frame 30 is disassembled from the second positioning portion 511 of the first connecting section 51 and / or the fourth positioning portion 421 of the second fixing frame 40 is disassembled from the fifth positioning portion 521 of the third connecting section 52, the first fixing frame 30 and the second fixing frame 40 have the risk of being disassembled from the first connecting section 51 and the third connecting section 52 respectively. In order to avoid the occurrence of such a risk, the connecting mechanism 98 further includes a first blocking portion 513, a second blocking portion 523, a third blocking portion 33 and a fourth blocking portion 43. The first blocking portion 513 and the second blocking portion 523 are closer to the ends of the first fixing frame 30 and the second fixing frame 40 that are separated from each other than the second positioning portion 511 and the fifth positioning portion 521. The first blocking portion 513 and the second blocking portion 523 are one of a protrusion and a limiting groove, and the third blocking portion 33 and the fourth blocking portion 43 are the other of the protrusion and the limiting groove. In this embodiment, the two ends of the first connecting section 51 and the third connecting section 52 that are separated from each other are protruded downward to form a first blocking portion 513 and a second blocking portion 523, and corresponding positions of the first fixing frame 30 and the second fixing frame 40 are provided with limiting grooves to form the third blocking portion 33 and the fourth blocking portion 43. When the first positioning portion 321 of the first fixing frame 30 is disassembled from the second positioning portion 511 of the first connecting section 51 and / or the fourth positioning portion 421 of the second fixing frame 40 is disassembled from the fifth positioning portion 521 of the third connecting section 52, the first blocking portion 513 and the second blocking portion 523 cooperate with the third blocking portion 33 and the fourth blocking portion 43, respectively, to prevent the first fixing frame 30 and the second fixing frame 40 from being disassembled from the first connecting section 51 and the third connecting section 52, respectively.

[0035] Please see Figure 7-9The present invention also provides a splicing handwriting board 99, including a connecting mechanism 98, a first handwriting board 10 and a second handwriting board 20, wherein the connecting mechanism 98 includes a first fixing frame 30, a second fixing frame 40 and a connecting member 50, and the backs of the first handwriting board 10 and the second handwriting board 20 are fixed to the first fixing frame 30 and the second fixing frame 40. When the first fixing frame 30 and the second fixing frame 40 are in a splicing state, the first handwriting board 10 and the second handwriting board 20 remain spliced; when the first fixing frame 30 and the second fixing frame 40 are in a folded state, the fronts of the first handwriting board 10 and the second handwriting board 20 are in contact with each other. In this embodiment, the number of the connecting mechanisms 98 is two, and the two connecting mechanisms 98 are arranged at intervals between the first handwriting board 10 and the second handwriting board 20. The connecting mechanism 98 has been described above and will not be repeated here.

[0036] In the above-mentioned spliced ​​handwriting board 99, when the first connecting section 51 and the third connecting section 52 are in a folded state, the first fixing frame 30 and the second fixing frame 40 are folded in half; when the first connecting section 51 and the third connecting section 52 are in a flat state, the first fixing frame 30 and the second fixing frame 40 can slide relative to each other along the connecting member 50 to be spliced ​​together, or can slide in the opposite direction along the connecting member 50 to be separated, thereby avoiding exposing the liquid crystal film of the spliced ​​handwriting board 99 to the outside world, and avoiding damage caused by collision between the liquid crystal module and the outside world during transportation.
