At this time, the relative positions of the first cover 10 and the second cover 20 are called is the second position B; when the first cover 10 moves to the second position B, since at least one engaging portion 13 has a space 131, at least one fixing pin 14 is no longer pushed by the first cover 10 Then, by the pulling force provided by the elastic element 21 in the direction of the side wall, it is pressed against the space 131 of the at least one engaging portion 13 to complete the interlocking between the at least one fixing pin 14 and the at least one engaging portion 13 .

Wherein, at least one engaging portion 13 is preferably respectively adjacent to the two side walls of the first cover 10 provided with a plurality of buckle grooves 11, and at least one fixing pin 14 is provided adjacent to at least one engaging portion 13. The two sidewalls of the second cover 20 of the plurality of fastening portions 12 are, however, only for example and should not be limited thereto.

During the disassembly process, an external force will be applied from the side wall of the second cover 20 to the pressing portion 142 towards the inside of the second cover 20, and then the pressed pressing portion 142 will drive at least one fixing pin 14 to be buckled relative to each other. The direction displacement of part 12, that is to drive at least one fixing pin 14 out of the space 131 of at least one engaging part 13, so that at least one fixing pin 14 and at least one engaging part 13 are out of the buckled state; finally the first cover 10 slides from the second position B back to the first position A along the plurality of fastening portions 12 to complete the disassembly operation of the first cover 10 and the second cover 20 .

According to the aforementioned first embodiment, the utility model further proposes a second embodiment for further illustration. Please refer to Figure 6 to Figure 12; Figure 6 is the first side sectional view of the assembly of the first cover and the second cover of the buckle structure of the present invention; Figure 7 is the second side view of the buckle structure of the present invention The second side sectional view of the assembly of the first cover and the second cover of the embodiment; FIG. 8 is the third assembly of the first cover and the second cover of the second embodiment of the buckle structure of the present invention Side sectional view; FIG. 9 is a partial side sectional view of the adjustment member and part of the buckle structure of the utility model; FIG. 10 is a dismounted first cover of the second embodiment of the buckle structure of the present utility model Body and the second cover first disassembly side view; Fig. 11 is the first disassembly side view of the first cover and the second cover of the second embodiment of the buckle structure of the present utility model; Fig. 12 is the first disassembly side view of this utility model A top sectional view of the fixing pin seat of the buckle structure of the utility model.

In this embodiment, the buckle structure 1 may include at least one fixing pin seat 15, which are respectively adjacent to one side of the at least one fixing pin 14 opposite to the inclined surface 141; and at least one fixing pin seat 15 may have at least one slot 151, the side of at least one fixing pin 14 corresponds to at least one card slot 151 with at least one protrusion 143, and each protrusion 143 is movably fitted into each card slot 151, and at least one card slot 151 defines at least one fixed The displacement direction of the pin 14. In addition, at least one fixing pin 14 may have an adjustment hole 144 , and the second cover 20 is provided with an adjustment opening 22 corresponding to the adjustment hole (which may correspond to a cooling hole, a trumpet hole or other appearance holes provided on the second cover 20 ). However, the above are examples only, and are not limited thereto.

In the second embodiment, the process of assembling and disassembling the first cover 10 and the second cover 20 will be described in detail in the next paragraph.

During the assembly process, the first cover 10 slides from the first position A along the plurality of fastening parts 12, and pushes against the slope 141 of at least one fixing pin 14 during the sliding process, so as to drive at least one fixing pin 14 along the At least one slot 151 is displaced in a direction relative to the first cover 10, and at least one fixing pin 14 simultaneously compresses the elastic element 21, and the elastic element 21 also pushes at least one fixing pin 14 toward the first cover 10. elastic.

Next, when the first cover 10 moves from the first position A to the second position B, the positions of at least one engaging portion 13 and at least one fixing pin 14 will correspond to each other, and at least one engaging portion 13 has corresponding at least one fixing pin. The space 131 of the pin 14; thereby, when at least one fixed pin 14 is in the second position B, it will not be pushed by the first cover body 10, but can be pushed along the slot by means of the pushing elastic force provided by the elastic element 21 151 abuts against the space 131 of at least one engaging portion 13 , so that at least one fixing pin 14 engages with at least one engaging portion 13 .

Wherein, at least one engaging portion 13 is preferably adjacent to the other side wall of the opposite side wall of the first cover 10, and at least one fixing pin 14 is corresponding to the at least one engaging portion 13 adjacent to the opposite side wall of the second cover 20. The other side wall of side wall, however, this is only for example, should not be limited to this.
