The working principle and the concrete implementation action of the invention are explained as follows:

as shown in fig. 11 and fig. 3 to 5, two ends of the toilet cover are connected to the exposed damping shafts 51 at two ends of the hinge pipe 10, and the two supports 30 are fixed on the rear part of the top surface of the ceramic toilet at intervals; the through hole 12 of the hinge pipe 10 is aligned with the lock pin 31 on the support 30, so that the lock pin 31 penetrates through the through hole 12 and is inserted into the radial insertion hole 211 on the fixed shaft 21, in the process that the lock pin 31 is inserted into the insertion hole 211, the circular truncated cone 311 at the top end of the lock pin 31 penetrates through the lock sheet 221 and pulls the lock piece 22 to move towards the fixed shaft 21, the inner plate of the lock piece 22 compresses the spring 23, after the circular truncated cone 311 sweeps over the circular truncated cone 311, the lock pin 31 is inserted into the insertion hole 211 in place, the lock groove 312 on the lock pin 31 gives way to the inner edge of the lock sheet 221, the lock piece 22 moves reversely under the action of the spring 23 and resets, the inner edge of the lock sheet 221 is clamped into the lock groove 312, the lock pin 31 cannot be pulled out of the fixed shaft 21 and the hinge pipe 10, and the quick mounting connection between the toilet cover and the ceramic toilet can be realized.

If the toilet cover needs to be detached from the top surface of the ceramic toilet, as shown in fig. 6 to 8, the button 41 in the middle of the hinge tube 10 is manually pressed, the pressure spring 42 is pressed and compressed by the fixing sleeve 411, the actuating magnet 43 on the back surface of the button 41 moves to a position between the actuated magnet 44 exposed to the S pole and the actuated magnet 45 exposed to the N pole and the actuating magnet 43, the S pole of the actuating magnet 43 repels the actuated magnet 44 exposed to the S pole, and the N pole of the actuating magnet 43 repels the actuated magnet 45 exposed to the N pole, so that the lock member 22 is displaced by a magnetic repulsion force for a stroke, and the spring 23 is compressed, as shown in fig. 2 and 5, the locking piece 221 retreats from the insertion hole 211 to be separated from the locking groove 312 on the locking pin 31 of the support 30, so as to realize the unlocking of the locking member 22 to the locking pin 31, and the elastic clip hook 222 clips the locking pin 31 so as to temporarily position the displacement stroke of the locking member 22, i.e. realize the unlocking stroke self-locking of the locking member 22; when the push button 41 is released as shown in fig. 9, the push button 41 is retracted and returned by the restoring force of the pressing spring 42, and the actuator magnet 43 is returned. As shown in fig. 10, fig. 11 and fig. 5, the lock pin 31 is pulled out from the insertion hole 211 and the through hole 12, so that the lock pin 31 is separated from the fixed shaft 21 and the hinge pipe 10, and the toilet cover can be detached from the top surface of the ceramic toilet.

As shown in fig. 10, 11 and 5, when the latch 31 is pulled out from the insertion hole 211, the elastic clip hook 222 loses the held latch 31, the lock control member 22 is pushed by the restoring force of the spring 23 to retreat and return, and the actuated magnet 44 exposed to the S pole and the actuated magnet 45 exposed to the N pole move toward each other and return.

As shown in fig. 5, the sliding block M in sliding fit between the lock control member 22 and the tube cavity 11 of the hinge tube 10 is used for installing the driven magnet, in order to reduce the frictional resistance between the lock control member 22 and the tube cavity 11, the sliding block M adopts a contact surface where the edges of the inner plate 223 and the outer plate 225 are in approximate line contact with the tube cavity 11, so that the frictional resistance of the lock control member 22 is greatly reduced, the driven magnet is inserted and fixed on the extension frame 224 between the inner plate 223 and the outer plate 225, and the lock control member 22 and the driven magnet thereon can be ensured to be displaced in the axial direction of the hinge tube 10, and the lock control member 22 cannot be jammed when displaced due to deviation.

Compared with the traditional or existing one-key type toilet cover plate dismounting structure, the invention utilizes the key 41 to drive the magnetic pole end of the actuating magnet 43 to shift to the magnetic pole end of the driven magnet at the end of the lock control piece 22 for contraposition, the magnetic repulsion force actuates the lock control piece 22 for a larger displacement stroke, and the lock control piece 22 is ensured to control the lock catch 20 to unlock the lock pin 31 in place; the possibility of tripping failure caused by the incomplete stroke of the contact type rigid bidirectional top pressure control lock catch can be avoided.
