In one embodiment, as shown in fig. 3 to 7, a self-locking structure is arranged between the first support 4 and the second support 5, when the foldable basin 1 is pressed to be folded and the first support 4 moves towards the second support 5, the self-locking structure automatically locks the first support 4 on the second support 5, and when the foldable basin 1 is pressed again, the self-locking structure is unlocked, and then the first support 4 and the second support 5 can be separated. Make the lavipeditum ware folding pressing manually through the user, on the semi-automatic folding lavipeditum ware that the lavipeditum ware was opened is realized to folding piece through driving piece drive, need set up self-locking structure and come the locking to keep fold condition continuously at the lavipeditum ware under the folding condition, this scheme can realize pressing down the automatic locking of in-process that makes the lavipeditum ware folding through setting up self-locking structure and keep fold condition, and can carry out the unblock automatically again when pressing the folding basin body once more, the structure of this kind of auto-lock makes the user open very good operation when folding basin body, product convenient to use.

In some embodiments, the self-locking structure comprises a locking member 8 and a locking hole 81, and the locking member 8 can movably lock the first bracket 4 on the second bracket 5. The locking piece 8 is a lock catch, the lock catch is arranged on the side wall of the first support 4, a lock hole 81 is arranged at the position corresponding to the lock catch on the side wall of the second support 5, and the first support 4 can be locked on the second support 5 when the lock catch is buckled in the lock hole 81. The self-locking is realized through the mode of the lock catch, the self-locking structure is reliable and stable, and the structure is simple and easy to manufacture.

The locking hole 81 is formed by connecting a plurality of slide ways in sequence as shown in fig. 6 so as to cooperate with the locking member 8. In order to realize the balance of locking, the number of the locking pieces 8 is four, the locking pieces are symmetrically arranged on two side walls of the first support 4, correspondingly, the number of the locking holes 81 of the second support 5 is four, the locking stability can be ensured, and the foldable basin body 1 cannot be opened accidentally. The bottom of locking piece 8 is equipped with locking point 80, and one side of locking piece 8 is connected with the spring of spring etc. and is not shown in the figure, lets locking piece 8 can swing and can reply the vertical state through the reply of spring relatively first support 4, and the middle part of locking piece 8 is rotated through the pivot and is connected on first support 4. Correspondingly, a self-locking detent 82 is provided in the locking hole 81.

Self-locking structure is still including setting up the direction muscle 83 on first support 4 inside wall, the lockhole 81 includes entrance point and exit end, screens point 82 is located between entrance point 811 and exit end 812, when folding basin body 1 is folding, first support 4 is during towards second support 5 motion, direction muscle 83 leads so that lockpoint 80 swings and gets into entrance point 811 to lockpoint 80, locking piece 8 slope this moment, the spring has stored elastic potential energy, when pressing folding basin body 1 once more, lockpoint 80 resets under the elastic restoring force effect of elastic component, lockpoint 80 moves to exit end 812 and breaks away from lockhole 81 locking piece 8 and returns vertical state from screens point 82, first support 4 and the unblock of second support 5 this moment, folding basin body 1 can be opened under the driving piece effect. The locking point of the locking piece automatically enters the lock catch through the guide rib and then is automatically locked on the clamping point, the clamping point can be separated from the lock hole from the outlet end after the folding pot body is pressed again, locking and unlocking are all completed in the lock hole, and the structural design is ingenious and easy to manufacture.

Under the condition that the driving piece is the return spring 7, because the upper cover 2 is arranged on the inner cavity of the folding pot body 1, the user can press the folding pot body by pressing the upper cover 2 more conveniently. When the user pressed the upper cover 2, folding basin body 1 was in the process of folding gradually, and sliding end 60 moved toward the direction of keeping away from rotation end 61 along spout 9 in folding process, rotated end 61 this moment and rotated clockwise to drive extension rod 610 and outwards pulled reset spring 7, realized the folding downwards of connecting rod 6, and reset spring 7 has stored elastic potential energy at this in-process. Meanwhile, the first bracket 4 is gradually close to the second bracket 5, when the locking piece 8 locks the two brackets, the folding of the folding pot body 1 is completed, and the return spring 7 is stretched to the maximum length at the moment. When folding basin body 1 is opened to needs, the user is the underground pressure upper cover 2 once more for 8 unblocks of locking piece, thereby reset spring 7 will the reconversion release its elastic potential energy this moment, and reset spring 7 pulling extension rod 610 anticlockwise rotates, and extension rod 610 and then drive rotate end 61 anticlockwise rotation, and slip end 60 is opened down at the rotation of rotating end 61 and is moved towards the direction of being close to rotating end 61, realizes upwards opening of connecting rod 6. Meanwhile, the first support 4 is unlocked from the second support 5 and moves upwards under the pushing of the connecting rod 6, and meanwhile, the upper cover 2 is pushed upwards, so that the folding pot body 1 is opened, and the folding pot body 1 is opened upwards.
