When the tension of the tension spring 401 makes the first slider 402c-1 slide in the first upper straight groove 104c and the second slider 402c-2 slide in the second upper straight groove 105c, the arc surface 402b-2 abuts against the clamping block 201d, the protection plate 402a deflects, the arrangement of the lifting groove 104g can make the protection plate 402a deflect by taking the axis of the second slider 402c-2 as the rotation axis until the clamping groove 402b-1 and the clamping block 201d are clamped, and locking of the sliding cover 201 is completed, if the sliding cover 201 is drawn, the clamping block 201d and the clamping groove 402b-1 are clamped, the protection cover 402 slides together, and the protection cover 402 cannot slide towards the sliding rail 102 because the sliding cover 201 is positioned between the sliding rail 102 and the protection cover 402, so that the sliding cover 201 cannot slide out, dislocation of the electric core seat 103 and the electric core plate 202 can be avoided, and communication of a circuit is ensured.
When the smoke audible and visual alarm 300 is disassembled, the protection plate 402a is rotated to deflect by taking the axle center of the second sliding block 402c-2 as the rotation axle center, so that the clamping groove 402b-1 and the clamping block 201d lose clamping, and the sliding cover 201 can be pulled out at the moment, and the disassembly of the smoke audible and visual alarm 300 is completed.
It should be noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present invention may be modified or substituted without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered in the scope of the claims of the present invention.
