Since one end of the limiting plate is hingedly connected with the plug-in block, the limiting plate can be flipped over after being penetrated out of the penetrating groove. The anti-flipping component arranged between the blocking plates can prevent the blocking plate from rotating in the opposite direction after being flipped over in the direction close to the blocking plate, so that the limiting plate can more stably limit the plug-in block from being pulled out of the penetrating groove.

[0014] Preferably, the anti-flipping component comprises a first magnet embedded on the side wall of the blocking plate away from the decorative plate and a second magnet arranged on the limiting plate and capable of being attracted to the first magnet.

[0015] With the above scheme, the second magnet arranged on the limiting plate can be attracted to the first magnet of the blocking plate fan after the limiting plate is penetrated out of the penetrating groove and rotated, thereby reducing the probability of automatic flipping of the limiting plate and making the limiting of the decorative plate by the limiting plate more stable.

[0016] Preferably, an accommodation groove for accommodating the limiting plate penetrated through the penetrating groove and rotated is arranged on the end of the blocking plate away from the decorative plate, and the first magnet is embedded in the accommodation groove.

[0017] With the above scheme, the accommodation groove arranged on the blocking plate can accommodate the limiting plate after the limiting plate is flipped over, thereby reducing the probability of the second magnet on the limiting plate being separated from the first magnet on the blocking plate due to accidental touch by the operator and making the limiting of the decorative plate by the limiting plate more stable.

[0018] Preferably, the end of the limiting plate away from the bottom of the accommodation groove is flush with the side wall of the blocking plate away from the decorative plate when the limiting plate is accommodated in the accommodation groove.

[0019] With the above scheme, when the limiting plate is accommodated in the accommodation groove, the end of the limiting plate away from the bottom is flush with the end of the blocking plate away from the decorative plate, thereby improving the overall aesthetics of the limiting plate when it is accommodated in the accommodation groove and further reducing the probability of accidental touch of the limiting plate by the operator, making the limiting of the decorative plate by the limiting plate more stable.

[0020] Preferably, the end of the blocking plate away from the decorative plate is provided with an operation groove for facilitating the operator to flip over the limiting plate accommodated in the accommodation groove.

[0021] With the above scheme, the operation groove arranged on the blocking plate can facilitate the operator to rotate the limiting plate to separate it from the accommodation groove.

[0022] The utility model discloses a blocking plate is arranged on hinge body, and the blocking plate can abut with the lateral wall of the decorative plate when the decorative plate horizontally slides to the specified position on the hinge body, thereby limiting the movement of the decorative plate along the horizontal direction, and the vertical anti -drop component arranged between the decorative plate and the hinge body can reduce the probability of the vertical drop of the decorative plate from the hinge body, and the horizontal anti -drop component arranged between the decorative plate and the blocking plate can reduce the probability of the horizontal drop of the decorative plate from the hinge body, thereby realizing the installation between the decorative plate and the blocking plate, and the installation between the decorative plate and the hinge body only needs to horizontally install the decorative plate to the hinge body and limits the position of the decorative plate through the horizontal anti -drop component and the vertical anti -drop component, and the assembly between the decorative plate and the blocking plate can be realized, thereby making the installation between the decorative plate and the blocking plate more convenient and fast.
