[0039] The technical solutions and beneficial effects of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] like Figure 1 and Figure 2 As shown, a toilet quick-release assembly includes a sleeve 1, a button assembly 2, a lock assembly 3, a damper 4 and a support 5.

[0041] Among them, Figures 4 to 10 As shown, the lock assembly 3 includes a lock body 31, a spring 32, and a locking plate 33. The lock body 31 is provided with a sliding guide groove 311. A first latch hole 312 is radially disposed in the lock body 31, which engages with the support 5. An insertion section 30 is axially disposed, perpendicular to the first latch hole 312. The lock body 31 defines an internal space 310 within which the main portion of the locking plate 33 slides. A step 313 is formed between this internal space 310 and the insertion section 30.

[0042] The locking plate 33 includes a locking tongue 331 and an unlocking tongue 332 at one end and an unlocking bevel 333 at the other end. The locking tongue 331 and unlocking tongue 332 are formed as a single-layer composite and each comprised of two parts, symmetrically arranged in an open position on two arms 330. The arms 330 are thicker at their bases and taper gradually toward the unlocking tongue 332. The unlocking tongue 332 and locking tongue 331 are located at the ends of the arms 330, while the locking tongue 331 extends further outward from the unlocking tongue 332 in a sheet-like shape. This creates a bend between the two arms 330 at the unlocking tongue 332, creating a larger gap between the two arms 330. The net internal diameter of the bend is greater than the diameter of the latch 51. A first and second limiting plates 334 and 335 are spaced apart between the ends of the locking plate 333. The first limiting plate 334 is provided with a sliding plate 3341 that can slide along the sliding guide groove 311. The locking plate 33 is movably mounted within the lock body 31. Specifically, after the locking plate 33 passes through the spring 32, one end of the spring 32 abuts against the first limiting plate 334, and the other end abuts against the internal step 313 of the lock body 31. When the spring 32 is in a released state, its unlocking slope 333 extends from one end of the lock body 31, and its locking tongue 331 extends into the socket section 30 and faces the first pin hole 312.

[0043] like Figure 3As shown, the damper 4 includes a shaft core 41 and a body portion 42. The shaft core 41 is provided with a second latch hole 410 and a locking plate groove 411. The shaft core 41 is adapted to fit within the insertion hole section 30. The second latch hole 410 is opposite the first latch hole 312, and the locking plate groove 411 is adapted to receive the unlocking tongue 332 and the locking tongue 331 of the locking plate 33. The shaft core 41 of the damper 4 is connected to the lock assembly 3 via the insertion hole section 30. The body portion 42 is rotatably connected to a rocker arm 6 fixedly mounted on the toilet lid. In this way, when the toilet lid is flipped, the body portion 42 of the damper 4 can rotate relative to its shaft core 41.

[0044] like Figures 12 to 16 As shown, the button assembly 2 is radially mounted on the sleeve 1 and includes a base 21, a spring 22, and a button 23. The bottom end of the button 23 is provided with a push ramp 231. The button 23 is slidably mounted on the base 21 via the spring 22. Specifically, the base 21 includes symmetrically arranged buckle slots 211, with a guide slot 212 positioned between the two buckle slots 211. Correspondingly, the button 23 is provided with a buckle 232 and a guide rib 233, which engage with the buckle slots 211 and the guide slot 212, respectively. A positioning post 213 is provided at the bottom of the base 21, with a spring 22 positioned between the positioning post 213 and the button 23.

[0045] The unlocking inclined surface 333 of the locking piece 33 is axially arranged in the sleeve 1 and abuts the pushing inclined surface 231. When the button 23 is pressed relative to the base 21, the pushing inclined surface 231 thereon acts on the unlocking inclined surface 333 of the locking piece 33, thereby causing the locking piece 33 to move axially.

[0046] The working principle of the toilet quick-release assembly using the above structure is as follows:

[0047] like Figures 17 to 22 As shown, in the initial state, the spring of the button assembly 2 is in a released state. At this time, the spring 32 of the lock assembly 3 is also in a released state. The lock tongue 331 of the lock plate 33 clamps the latch 51 of the support 5. At this time, the lock assembly 3 is in a locked state; when the cover needs to be removed, press the button 23, the spring 22 is compressed, and the pushing inclined surface 231 acts on the unlocking inclined surface 333, thereby compressing the spring 32, causing the lock plate 33 to move axially, so that the latch 51 squeezes the unlocking tongue 332 inward, so that the two arms 330 open. When the latch 51 passes over the unlocking tongue 332, the two arms 330 return to their original state, and the latch 51 enters the inside of the two arm bends, completing the unlocking of the latch 51 of the support 5. At this time, keep the state of the button 23, pull the toilet cover hard, and the toilet cover can be removed.

[0048] The above embodiments are only for illustrating the technical idea of the present invention and cannot be used to limit the protection scope of the present invention. Any improvements and equivalent replacements made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
