Mortise structures 24 are provided on both sides in the width direction of the notch 22, and tenon structures 25 corresponding to the mortise structures 24 are provided on both sides in the width direction of the pressing block member 23.
[0028] It can be understood that by stacking a number of BT boards flat in sequence at intervals with sulfur-free paper in the box body 10, fixing the cover plate component 21 on the box body 10 through the buckle assembly 30, putting the pressing block component 23 into the notch 22 and making the tenon structures 25 on both sides in the width direction of the pressing block structure 23 correspond to the mortise structures 24 on both sides in the width direction of the notch, so that the pressing block structure 23 moves towards the BT board in the notch 22 until it abuts against the BT board at the top inside the box body 10, so that the BT board inside the box body 10 is fixed and flattened by the self-weight of the pressing block structure 23. Furthermore, after the BT board is completely cured and shaped by the long-baking glue, it will no longer warp and deform, reducing the process difficulty and solving the quality hidden danger at the same time, facilitating the cutting of the subsequent board pasting process, and avoiding the bad risks such as chip dark cracks.
[0029] Furthermore, the buckle assembly 30 includes a connecting seat 31 threadedly connected to the cover plate component 21, a buckle structure 32 hinged to the connecting seat 31, and an elastic structure 33 elastically connecting the connecting seat 31 and the buckle structure 32.
[0030] Furthermore, on the side of the connecting seat 31 away from the box body 10, there is a first spring groove 311 for elastically connecting the elastic structure 33, and through holes 312 for hinging the buckle structure 32 are arranged on both sides of the connecting seat 31.
[0031] Furthermore, the buckle structure 32 includes a fixing member 321, a protruding portion 322 provided on the side of the fixing member 321 facing the connecting seat 31, and a second spring groove 323 provided above the protruding portion 322 for elastically connecting the elastic structure 33. A connecting rod 324 is fixedly connected to the protruding portion 322, and the connecting rod 324 is rotatably arranged in the through hole 312.
[0032] Furthermore, a hook structure 325 is provided at one end of the fixing member 321 away from the second spring groove 323, and a card slot 14 for connecting the hook structure 325 is provided on the side of the bottom of the box body 10 away from the hinge structure 11.
[0033] It can be understood that when the cover plate component 21 is fixed to the box body 10 by the buckle assembly 30, by swinging the fixing member 321 away from the box body 10 to disengage the hook structure 325 from the card slot 14, and then lifting the cover plate component 21, the box body 10 can be opened; when it is necessary to fix the cover plate component 21 to the box body 10 by the buckle assembly 30, by swinging the fixing member 321 away from the box body 10 to move the hook structure 325 away from the card slot 14, and the second spring groove 323 squeezes the elastic structure 33, after the cover plate component 21 is abutted against the top of the box body 11, the fixing member 321 is released, and the hook structure 325 is connected and fixed in the card slot 14 by the tension of the elastic structure 33.
[0034] Furthermore, an abutting assembly 40 for pushing the pressing block component 23 is provided on the top of the connecting seat 31. The abutting assembly 40 includes a support rod 41 threadedly connected to the top of the connecting seat 31, a connecting screw rod 42 threadedly connected to one end of the support rod 41 away from the connecting seat 31, and a push block structure 43 threadedly connected to the connecting screw rod 42.

[0035] Furthermore, the cross-sectional area of the push block structure 43 is smaller than that of the notch 23, and the push block structure is 43 I-shaped.
[0036] It can be understood that after the BT board is placed in the box body 10, by rotating the connecting screw rod 42 counterclockwise, the push block structure 43 moves axially towards the pressing block component 23 until it abuts against the pressing block component 23 to fix the pressing block component 23 against the BT board on the inner top of the box body 10, so that the BT board in the box body 10 is further fixed and flattened by the push block structure 23; after the BT board completes long baking, by rotating the connecting screw rod 42 clockwise, the push block structure 43 moves axially away from the pressing block component 23, thereby releasing the BT board fixed by the pressing block component 23.
[0037] Furthermore, a stop structure 26 is provided at the bottom of the mortise structure 24.
[0038] It can be understood that by providing the stop structure 26, the push block structure 23 is prevented from falling into the box body 10.
[0039] Furthermore, a plurality of ventilation holes 12 are opened on the outer side of the box body 10, and an overflow glue groove 13 is arranged around the ventilation holes 12 at the bottom of the box body 10.
[0040] It is understandable that by providing the ventilation holes 12, the air convection inside the box body 10 is increased, and by providing the glue overflow groove 13, it can prevent the epoxy glue extruded when the pushing block structure 23 flattens the BT board from overflowing randomly.
[0041] Furthermore, a buffer layer 27 is provided on the side of the pressing block component 23 facing the BT board, and the buffer layer 27 is square.
[0042] It is understandable that by providing the buffer layer 27, it can play a buffering and protecting role when the pushing block structure 23 abuts against the BT board, avoiding damage to the BT board.
[0043] In summary, for the fixture for preventing warping of the BT board in the above embodiments of the present invention, a plurality of BT boards are stacked flatly at intervals in the box body in sequence using sulfur-free paper, the cover plate component is fixed on the box body through the buckle assembly, and the pressing block component is placed in the notch, and the tenon structures on both sides in the width direction of the pressing block structure correspond to the mortise structures on both sides in the width direction of the notch, so that the pressing block structure moves towards the BT board in the notch until it abuts against the BT board at the top inside the box body, so that the BT board inside the box body is fixed and flattened by the self-weight of the pressing block structure. Furthermore, after the BT board is completely cured and shaped by the long-baking glue, it will no longer warp and deform, reducing the process difficulty and solving the quality hidden danger at the same time, facilitating the cutting of the subsequent board pasting process, and avoiding adverse risks such as chip dark cracks.
