The first side end 213 of the guiding side plate 21 clings to the inner side wall of the basin 2, the second side end 214 thereof is exposed as a yielding structure of the fastening seat 20, the direction extending outward from the second side end 214 is a yielding direction, and the yielding direction is 90 ° to the guiding direction. Preferably, the leading-in direction and the yielding direction are approximately perpendicular (approximately perpendicular means approximately 90 degrees, and a certain angle deviation range is allowed, for example, the deviation is within a range of 5 degrees), the angle is large, false triggering can be effectively avoided, and interference is small. Of course, the angle between the receding direction and the introducing direction is not limited to this, and may be 45 ° or 60 ° with respect to each other.

More specifically, in this embodiment, the basin 2 has two opposite inner side walls, and the two hidden locking fixtures are respectively located on the two opposite inner side walls of the basin 2, that is, the two locking seats 20 of the hidden locking fixtures are respectively located on the two opposite inner side walls of the basin 2, and the two locking connectors 10 are respectively located on the wall surface 1 and correspond to the two locking seats 20. Thus, the second side ends 214 of the two clamping seats 20 are also oppositely arranged. When the wash basin 2 is dismounted, as shown in fig. 6, the wash basin 2 is swung left and right, and when the wash basin swings left, the clamping seat 20 on the left side moves left, and the clamping connector 10 on the left side is separated from the second side end 214 of the clamping seat 20; when swinging to the right, the right clamping seat 20 moves to the right, and the right clamping connector 10 is separated from the second side end 214 of the clamping seat 20; because the elastic support arm 11 has a certain elasticity, the elastic support arm 11 will not be broken as long as the swing amplitude satisfies the elastic deformation range of the elastic support arm 11 during the process of swinging left and right. In this way, complete and complete disengagement can be achieved.

Of course, in other embodiments, if the first side end 213 and the second side end 214 of the clamping seat 20 are exposed, they can be used as an abdicating structure for the clamping head 10 to disengage. Or, the yielding structure and the introducing structure are at other angles, such as 45 degrees and 60 degrees, etc., and the yielding structure and the introducing structure can be moved outwards by inclining the angle direction, so long as the yielding structure can be moved out along the yielding structure.

More specifically, the second side end 214 of the abdicating structure is further provided with a limiting step 24 in a protruding manner, and the limiting step 24 is configured to prevent the clamping connector 10 from being separated from the second side end 214 in the clamping process (i.e. the process of moving to the second end 212 through the first end 211 of the guide side plate 21), and only under the action of applying a sufficient external force, the elastic arm 11 of the clamping connector 10 and the clamping protrusion 12 thereon can cross the limiting step 24 and be separated from the clamping seat 20. Ensuring smooth clamping.

During installation, the basin 2 is close to the wall surface 1, the clamping connector 30 is guided in along the guiding direction through the guiding structure to realize clamping matching with the clamping seat 40. When needing to dismantle, change the moving direction of basin 2, joint 30 follows through the structure of stepping down under the joint state the direction of stepping down steps down and breaks away from joint seat 40 realizes the separation, can realize complete demolising, need not destroy mounting structure. Simultaneously, because joint and joint seat have the leading-in direction and the direction of stepping down that the angle is different, exist independently in same device, and take place the effect alone, can not cause the influence each other, can be fine be applicable to among the hidden mounting structure.

Specifically, in this embodiment, the clamping head 30 has two elastic arms 31 arranged at intervals, the end of each elastic arm 31 is provided with a clamping convex portion 32, and more specifically, the end of each elastic arm 31 protrudes outwards to form the clamping convex portion 32.

More specifically, the distance between the two elastic arms 31 is smaller, and the two elastic arms 31 gradually expand outward, and the two elastic arms 31 are combined inward to form a column.

The guide structure of joint seat 40 is a jack 401, two elastic support arms 31 of joint head 30 insert jack 401, joint convex part 32 passes jack 401 to the second end of jack 401 through the first end of jack 401 to the joint is on joint seat 40 under elastic force effect of elastic support arm 31. The specific process is as follows: the basin 2 has two opposite inner side walls, the hidden locking fixer has two, and is located on two opposite inner side walls of the basin respectively, namely the clamping seats 40 of the two hidden locking fixers are respectively arranged on two opposite inner side walls of the basin 2, and the two clamping connectors 30 are arranged on the wall surface 1 and respectively correspond to the two clamping seats 40. During the installation, basin 2 is close to wall 1, and two elastic support arms 31 insert jack 401 is leading-in through jack 401, and joint convex part 32 is contradicted in jack 401 inner wall, and elastic support arm 31 inwards draws close and produces elastic deformation, treats that joint convex part 32 wears out the second end of jack 401, accomplishes leading-in back promptly, and joint convex part 32 loses the conflict of jack 401 inner wall and makes elastic support arm 31 resume deformation, and then drives the outside expansion of joint convex part 32, and final joint is on joint seat 40. The extending direction from the first end to the second end of the insertion hole 401 is the leading-in direction.

Further preferably, in this embodiment, the aperture of the first hole section 41 of the insertion hole 401 near the first end thereof is larger than the aperture of the second hole section 43 near the second end thereof, a mounting hole 44 is opened on a side wall of the first hole section 41 of the insertion hole 401, the mounting hole 44 is used for mounting the snap seat 40 on the inner wall of the basin 2, and the specific mounting manner is the same as that of the first embodiment, and will not be described in detail herein.
