Detailed Description

The technical solution and the advantages of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, 2 and 11, a quick release device for a cover plate includes a pivot shaft 1, a support 2 and an operating member 3.

Wherein the pivot axis 1 is used for rotating the toilet cover plate around. The pivot shaft 1 is provided with a first slot 11 and a second slot 12 which are axially arranged in parallel and a radial insertion hole 13 which is communicated with the first slot 11 and the second slot 12. The pivot shaft 1 is provided with a stop block 5 at the ends of the first slot 11 and the second slot 12, and the stop block 5 has a guide inclined surface 51 inclined inward.

The support 2 is fixed to the toilet and is used for receiving the pivot shaft 1. The support 2 is provided with a plug 21 for insertion into the radial receptacle 13. More specifically, the bolt 21 comprises a cylindrical section 211 and an umbrella head 212 arranged at the tail end of the cylindrical section, and the maximum diameter of the umbrella head 212 is smaller than that of the cylindrical section 211, so that the bolt 21 can be inserted into or separated from the pivot shaft 1 more smoothly. An annular groove 213 for locking the latch 21 in the pivot shaft 1 is provided below the head 212.

As shown in fig. 9 and 10, the operating member 3 is used to lock or unlock the holder 2 with the pivot shaft 1. The operating element 3 includes an operating button 31, and a locking piece 32 and an elastic arm 33 provided in the operating button 31 and inserted into the first slot 11 and the second slot 12, respectively. The locking plate 32 is provided with a locking hole 321, the locking plate 32 extends towards two sides to form a limiting hook 322, correspondingly, the pivot shaft 1 is provided with a clamping hole 102 matched with the limiting hook 322, and the axial opening size of the clamping hole 102 is larger than the axial size of the limiting hook 322. This allows the latch 21 to be inserted into or removed from the pivot shaft 1 while the retaining hook 322 remains movable in the catch hole 102. By matching the limit hook 322 on the lock plate with the locking hole 102 on the pivot shaft 1, the operating element 3 cannot be disengaged from the pivot shaft 1 when the elastic arm 33 is reset. The locking piece 32 may be disposed above the elastic arm 33, or the elastic arm 33 may be disposed above the locking piece 32. The button 31 is pressed to move the locking piece 32 and the elastic arm 33 synchronously between the locking position and the unlocking position. The outside of the elastic arm 33 is provided with a hook 331, the end of the inside is provided with a hook 332, and the circumferential wall of the pivot shaft 1 is correspondingly provided with a limit slot 101 matched with the hook 331. The axial opening dimension of the catch 101 is larger than the axial dimension of the catch 331. This allows the catch 331 to remain movable within the catch 101 when the latch 21 is inserted into or removed from the pivot shaft 1.

In a preferred embodiment, two elastic arms 33 are arranged side by side in parallel, and the distance between the hooks 332 of the two elastic arms 33 is greater than or equal to the diameter of the plug 21. The thickness of the resilient arm 33 is greater than the thickness of the annular groove 213. This allows the bolt 21 to be inserted or removed more smoothly from the pivot shaft 1. Because the elastic arm 33 only needs to hang the bolt 21, and the distance between the two hooks of the elastic arm 33 is larger than or equal to the diameter of the bolt 21, the unlocking stroke of the button 31 can be realized only by the radius size of the bolt 21, the stroke is short, the axial size of the operating part 3 can be smaller, and the appearance of the product is more attractive. A return spring 4 is arranged between the pivot shaft 1 and the operating part 3, when the bolt 21 is pulled out of the pivot shaft 1, the elastic arm 33 is restored by the restoring force of the return spring 4 and the self elastic deformation, so that the hook 331 is restored, and the operating part 3 is restored.

With the above structure, when the latch 21 of the holder 2 is not inserted into the radial insertion hole 13 of the pivot shaft 1, the holder 2 is in a separated state from the pivot shaft 1. When the bolt 21 of the holder 2 is inserted into the radial insertion hole 13 of the pivot shaft 1, the holder 2 and the pivot shaft 1 are in a locked state, as shown in fig. 3 to 5, and at this time, the annular groove 213 on the bolt 21 is in limit fit with the edge of the locking hole 321 of the locking plate 32 of the operating element 3 to form a lock on the bolt 21. When the locking piece is disassembled, referring to fig. 6 to 8, the operating button 31 of the operating element 3 is pressed, the operating button 31 compresses the return spring 4 to deform, so that the locking piece 32 and the elastic arm 33 move axially and inwardly in the first slot 12 and the second slot 13, that is, the operating element 3 moves toward the pivot shaft 1, the locking piece 32 moves inwardly, the edge of the locking hole 321 is far away from the annular groove 213, the locking piece 32 is released from the limit of the annular groove 213, meanwhile, the hook 331 of the elastic arm 33 moves axially and inwardly along the locking groove, the hook 332 of the elastic arm 33 moves axially and inwardly, under the guide of the guide inclined plane 51 of the limit block 5, the bolt 21 is clasped, so that the tail end of the elastic arm 33 is kept in a slightly opposite-pressing state, the locking piece 32 is positioned at the unlocking position of the bolt 21, after the pivot shaft 1 is pulled away from the bolt 21 by applying force, the two elastic arms 33 are not hitched with the bolt 21, and the elastic arm 33 is restored to the original clasped state by the self elastic return force, i.e. initially in a state in which the latch 21 of the holder 2 is not inserted into the pivot axis 1.

The above embodiments are only for illustrating the technical idea of the present invention, and the protection scope of the present invention is not limited thereby, and any modifications and equivalents made on the basis of the technical idea of the present invention fall within the protection scope of the present invention.
