[0047] Further, the adjusting assembly comprises a supporting mechanism and a threaded rod, a sliding groove matched with the mounting rod 14 is arranged on the frame body, the threaded rod is threadedly connected with the frame body, one end of the threaded rod is connected with the mounting rod 14, the threaded rod drives the mounting rod 14 to move in the sliding groove when the threaded rod rotates, the supporting mechanism is arranged on the side frame one 1 for supporting the seat plate 15, and the length of the supporting mechanism can be adjusted. Further, the supporting mechanism comprises a supporting rod 10, a limiting block 11 and an adjusting seat 9, the adjusting seat 9 is arranged on the side frame one 1, the supporting rod 10 is movably arranged on the adjusting seat 9, one end of the supporting rod 10 is provided with a limiting rod 26, a plurality of limiting grooves 8 matched with the limiting rod 26 are arranged on the adjusting seat 9, and the limiting block 11 is arranged at the end of the supporting rod 10 away from the limiting rod 26. A clamping groove 22 matched with the supporting rod 10 is arranged on the seat plate 15.

[0048] In the above scheme, the specific process of adjusting the height of the seat plate is as follows: firstly, according to the needs of the user, the threaded rod is rotated to drive the mounting rod to move to the corresponding position on the frame body, and then the supporting rod is rotated to make the limiting rod at the lower end of the supporting rod clamped into the corresponding limiting groove on the adjusting seat, and the supporting rod is clamped into the clamping groove to support the seat plate.

[0049] It should be noted that, in order to ensure that the threaded rod can rotate normally, and at the same time prevent the lower end of the threaded rod from affecting the movement of the box body when the box seat is buckled with the box cover and contacted with the ground, the threaded rod is arranged to be composed of a threaded segment 13 and a rotating segment 16, the threaded segment 13 is threadedly connected with the frame body, one end of the threaded segment 13 is connected with the mounting rod 14, and the other end is hinged with the rotating segment 16, and a magnet 27 matched with the rotating segment 16 is arranged on the frame body at a position corresponding to the rotating segment 16. When the threaded rod is not used, the rotating segment can be folded to be attached to the lower end surface of the intermediate frame two and be attracted to the magnet 27.

[0050] In the embodiment, the box cover comprises an intermediate frame two 19 and side frames two 17 hinged on both sides of the intermediate frame two 19, and a folding groove 20 is arranged at the connection between the intermediate frame two 19 and the side frames two 17. It should be noted that, the side frame two is a right trapezoidal shape, and the intermediate frame two is a rectangular shape.

[0051] It should be noted that, in order to ensure that the threaded rod can rotate normally, and at the same time prevent the lower end of the threaded rod from affecting the movement of the box body when the box seat is buckled with the box cover and contacted with the ground, the threaded rod is arranged to be composed of a threaded segment 13 and a rotating segment 16, the threaded segment 13 is threadedly connected with the frame body, one end of the threaded segment 13 is connected with the mounting rod 14, and the other end is hinged with the rotating segment 16, and a magnet 27 matched with the rotating segment 16 is arranged on the frame body at a position corresponding to the rotating segment 16. When the threaded rod is not used, the rotating segment can be folded to be attached to the lower end surface of the intermediate frame two and be attracted to the magnet 27. Figure 5In the middle section, after the lid is folded, the lower rod is shorter than the upper rod, making the dulcimer stand unstable. Furthermore, the upper rod of the second side frame is shorter than the width of the dulcimer, thus it cannot properly support the instrument. Therefore, this design also includes two additional support frames, such as... Figure 11 As shown, the support frame 28 is trapezoidal and detachably connected to the side frame 17. A locking block 29 is provided at the upper end of the support frame 28. The support frame serves two purposes: firstly, it cooperates with the side frame 17 to provide auxiliary support; secondly, it increases the support area at the upper end of the dulcimer stand, allowing the dulcimer stand to hold the dulcimer well.

[0052] Specifically, the positioning method of the support frame and the second side frame is as follows: Figure 12 As shown, a limiting pin 31 is provided on the surface of the support frame 28 that mates with the side frame 27, and a fixing groove 32 is provided on the side frame 27 at the position corresponding to the limiting pin 31. The limiting pin has a convex cross-section, and the fixing groove specifically includes a circular hole and a rectangular groove. The diameter of the circular hole is larger than the width of the rectangular groove. The limiting pin enters the fixing groove through the rectangular hole and is then limited by the rectangular groove. Limiting holes are provided on both the support frame and the side frame 2, and pins 30 are inserted into these holes. After the support frame is installed, the pins 30 are inserted into the limiting holes to fix the support frame to the side frame 2.

[0053] To facilitate the movement of the box, several rolling wheels 12 are provided at the bottom of the box, several support blocks 6 are provided at the top of the box, and multiple handles 5 are also provided on the box.

[0054] Among them, a positioning groove is also provided at the upper end of the middle frame 2, and the display board 2 can be inserted into the positioning groove.

[0055] An auxiliary strap is also installed inside the case. When it is necessary to remove the dulcimer from the case, the auxiliary strap can be pulled to make the dulcimer protrude out of the case, and then the dulcimer can be taken out.

[0056] Specifically, positioning holes are provided on intermediate frame one, side frame one, intermediate frame two, and side frame two, such as... Figure 3 As shown, after the box base and box cover are fastened together, the rotation between the intermediate frame two and the side frame two is limited by inserting the two ends of the fixing nail 21 into the corresponding positioning holes on the intermediate frame two and the side frame two. The specific positions of the fixing nails are as follows: Figure 3 As shown; Figure 10 As shown, when the lid needs to be folded into a dulcimer stand, remove the fixing pins. After folding, insert both ends of the fixing pins into the corresponding positioning holes on the middle frame two and the side frame two to limit the rotation between the middle frame two and the side frame two. The specific positions of the fixing pins are as follows: Figure 10The folding and fixing of the box seat is as shown in Fig. 4. It is to be noted that the folding and fixing of the box seat is as described above and will not be described again here.

[0057] The above description is only for the best embodiments of the present application and should not be understood as limiting the claims. The present application is not limited to the above embodiments and the specific structure can be changed. Any changes within the protection scope of the independent claims of the present application are within the protection scope of the present application.
