The connecting rod and locking device 64 are arranged on the fixing plate 65, the fixing plate 65 is fixed on the rear end wall of the closestool, the occupied volume is reduced, and the connecting rod assembly 63 and the functional mechanism 62 can still be normally arranged at the rear end of the closestool.
The locking device 64 of the embodiment comprises a bracket 1, a supporting block 3, a stroke limiting block 2 and a locking rod 5;
the supporting block 3 is pivoted with the bracket 1, and a first channel 11 is arranged between the supporting block 3 and the bracket 1; the supporting block 3 is provided with a limiting groove 31, the limiting groove 31 is positioned on the side wall of the supporting block 3 close to one side of the bracket 1, and a second channel 12 is formed above the limiting groove 31;
the stroke limiting block 2 is pivoted to the supporting block 3 and used for guiding the locking rod 5 to enter the second channel 12 or the first channel 11 so as to realize locking and resetting of the locking rod 5;
the locking rod 5 is arranged between the supporting block 3 and the bracket 1 in a penetrating way;
when the locking rod 5 is positioned above the limiting groove 31 and below the stroke limiting block 2, the stroke limiting block 2 is in a turnover state, and the second channel 12 is opened; in a locking state, the locking rod 5 is positioned in the limiting groove 31; when the locking rod 5 is positioned above the stroke limiting block 2, the stroke limiting block 2 is in a falling state, and the second channel 12 is closed; in the reset state, the locking lever 5 is located in the first channel 11.
In this embodiment, the supporting block 3 is provided with a limiting step 33, and the limiting step 33 is arranged below the stroke limiting block 2.
The bottom of the supporting block 3 is pivoted with the support 1, and one side of the support 1 facing the supporting block 3 is provided with an abutting inclined surface 13. The supporting block 3 is provided with an inclined wall 32 matched with the abutting inclined surface 13, the bottom of the inclined wall 32 is the limiting groove 31, so that the opening of the limiting groove 31 faces to the inclined upper side, and the locking rod 5 can smoothly fall into the limiting groove 31 when falling.
The free end of the stroke limiting block 2 consists of a driving surface 21 and a guide surface 22, and the included angle between the driving surface and the guide surface is an acute angle. In this embodiment, the driving surface 21 is a lower bottom surface, and the locking rod 5 pushes against the driving surface 21 to realize that the stroke limiting block 2 turns upwards; the guide surface 22 then facilitates guiding the locking bar 5 down into the first channel 11.
