As shown in fig. 2 and 3, at this time, the fixing rod 30 is in inserting fit with the connecting seat 50, and the fixing rod 30 is inserted in place, the elastic piece 61a automatically moves from the unlocking position to the pre-locking position under the action of elastic force, that is, the elastic piece 61a is clamped into the clamping groove 62a, so that the fixing rod 30 and the connecting seat 50 are pre-locked.

As shown in fig. 4, in the process of locking the toilet seat 20, the locking member 40 is rotated, and one end of the locking member 40, which extends into the hollow cavity 51 of the connecting seat 50, moves along the concave arc surface 32 of the fixing rod 30 to drive the connecting seat 50 to move in the direction close to the wall body along the axial direction of the fixing rod 30 until the toilet seat 20 is tightly contacted with the wall body 10; meanwhile, the locking member 40 drives the link member 80 to move, and the link member 80 further drives the elastic sheet 61a to move from the pre-locking position to the unlocking position, that is, the elastic sheet 61a exits the slot 62a, so that the elastic sheet 61a and the slot 62a are released from limiting, and the fixing rod 30 and the connecting seat 50 can be separated when the toilet seat 20 needs to be detached.

Second embodiment

As shown in fig. 7 to 14, the main differences between the present embodiment and the first embodiment are: the locking member 40 drives the pre-locking mechanism 60 to move from the pre-locking position to the unlocking position at different times, in this embodiment, the locking member 40 drives the linkage member 80 when the locking member 40 unlocks the fixing rod 30 and the connecting seat 50. The linkage 80 drives the pre-locking mechanism 60 to move from the pre-locking position to the unlocking position; alternatively, the link 80 may move the pre-locking mechanism 60 from the pre-locking position to the unlocking position during the process of separating the fixing lever from the connecting socket 50.

The link 80 is reset under the action of elastic force, and when the fixing rod 30 is separated from the connecting seat 50, the pre-locking mechanism 60 is reset to the pre-locking position under the action of the elastic force.

Specifically, in this embodiment, the limiting portion adopts a blocking edge 62b arranged on the connecting seat 50, the elastic clamping piece adopts a spring pin 61b arranged on the fixing rod 30, and when the pre-locking mechanism 60 is in the pre-locking position, the spring pin 61b extends out of the fixing rod 30 and is in limiting fit with the blocking edge 62 b; when the pre-lock mechanism 60 is in the unlock position, the elastic pin 61b is retracted into the fixing rod 30. Specifically, the elastic pin 61b can be radially movably limited in the elastic pin mounting hole 31 of the fixing rod 30, and the outer end of the elastic pin 61b can extend out of the elastic pin mounting hole 31 to be limited and matched with the blocking edge 62 b.

The link 80 is slidably attached to the connecting seat 50, the link 80 is provided with an abutting portion 81 engaged with the elastic pin 61b, and a guiding inclined surface 82 engaged with the elastic pin 61b in a guiding manner is provided on a side of the abutting portion 81 away from the blocking edge 62 b.

In this embodiment, in the process of locking and fixing the fixing lever 30 and the connecting holder 50 by the locking member 40, the position of the elastic pin 61b when the fixing lever 30 is locked with the connecting holder 50 has two cases, the first case is: when the fixing rod 30 and the connecting seat 50 move relatively for a short distance, the position of the elastic pin 61b is at the position shown in fig. 12, and at this time, the elastic pin 61b corresponds to the abutting part 81 on the linkage piece 80, and the linkage piece 80 can directly link the elastic pin 61 b; the second case is: when the fixing lever 30 and the connecting seat 50 move relatively for a long distance, the position of the elastic pin 61b is the position shown in fig. 14, and at this time, the elastic pin 61b is dislocated from the abutting portion 81 on the link 80, and the link 80 cannot directly link the elastic pin 61 b.

For the first situation, the locking member 40 is in linkage fit with the pre-locking mechanism 60 through the linkage member 80, the locking member 40 drives the linkage member 80 to move, and the linkage member 80 further drives the elastic pin 61b to move from the pre-locking position to the unlocking position, so that the elastic pin 61b and the blocking edge 62b are released from limiting.

In the second case, the locking member 40 couples the link member 80, so that the link member 80 prevents the elastic pin 61b from being in limit engagement with the stop edge 62 b. In addition, since the link 80 is misaligned with the elastic pin 61b and cannot directly link the elastic pin 61b, a guide inclined surface 82 is required, and the elastic pin 61b can be retracted into the fixing lever 30 along the guide inclined surface 82 when the fixing lever 30 is withdrawn from the connecting seat 50 by the guide inclined surface 82.

As shown in fig. 10, in the process of inserting the fixing rod 30 into the connecting seat 50, the toilet seat 20 is moved toward the wall 10 along the arrow direction, and the elastic pin 61b is retracted into the fixing rod 30 (i.e., the pre-locking mechanism 60 is in the unlocking position).

As shown in fig. 11, when the fixing rod 30 is inserted into place, that is, when the elastic pin 61b corresponds to the stop edge 62b, the elastic pin 61b automatically extends out of the elastic pin mounting hole 31 to be in limit fit with the stop edge 62b, so as to achieve the pre-locking function of the fixing rod 30 and the connecting seat 50.

As shown in fig. 12, in the locking process of the toilet seat 20, the locking member 40 is rotated, and one end of the locking member 40, which extends into the hollow cavity 51 from the screw hole 53, moves along the concave arc surface 32 on the fixing rod 30, so that the connecting seat 50 moves toward the wall body relative to the axial direction of the fixing rod 30, and the toilet seat 20 presses the wall surface to be fastened; at the same time, due to the relative movement of the fixing rod 30 and the connecting seat 50, the elastic pin 61b is also far away from the blocking edge 62b and is no longer in limit fit with the blocking edge 62 b.

When the toilet seat body 20 is locked, the position of the elastic pin 61b is in the first condition, as shown in fig. 13, when the toilet seat body 20 is disassembled, the locking member 40 is rotated reversely, the locking member 40 exits from the hollow inner cavity 51 of the connecting seat 50 to release the locking of the fixing rod 30 and the connecting seat 50, meanwhile, the locking member 40 drives the link member 80 to move downwards, the abutting portion 81 of the link member 80 pushes the elastic pin 61b downwards, so that the elastic pin 61b loses the limit fit with the blocking edge 62b, that is, the elastic pin 61b moves to the unlocking position. Thereby making the toilet seat 20 detachable.

When the toilet seat body 20 is locked, and the position of the elastic pin 61b is in the second condition, as shown in fig. 14, when the toilet seat body 20 is disassembled, the locking member 40 is rotated reversely, the locking member 40 exits from the hollow cavity 51 of the connecting seat 50 to release the locking of the fixing rod 30 and the connecting seat 50, meanwhile, the locking member 40 drives the link member 80 to move downward, the abutting portion 81 of the link member 80 is engaged with the retaining edge 62b, so that the elastic pin 61b is prevented from being engaged with the retaining edge 62b in a limiting manner, at this time, an external force is applied to move the connecting seat 50 in a direction separating from the fixing rod 30, and under the action of the guiding inclined surface 82, the elastic pin 61b can retract into the fixing rod 30 along the guiding inclined surface 82, that is, the elastic pin 61b moves to the unlocking position.
