Detailed Description

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

As shown in fig. 1 to 4, a cover plate quick-release structure includes a hinge shaft 1, a support 2 and an operating member 3.

Wherein the hinge shaft 1 is used to rotate the toilet cover plate therearound. The hinge shaft 1 has a first slot 11 and a second slot 12 arranged in parallel in the axial direction and a radial insertion hole 13 communicated with the first slot 11 and the second slot 12. Wherein the second slot 12 forms a limit step 121 at the entrance.

The support 2 is fixed to the toilet bowl and receives the hinge shaft 1. The support 2 comprises a bolt 21 and a base 22, wherein the bolt 21 is divided into two sections, a thicker section is a bearing section 214, a thinner section is a pin body for inserting into the radial insertion hole 13, the pin body 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 more smoothly inserted into or separated from the hinge shaft 1. An annular groove 213 for locking the latch 21 in the hinge shaft 1 is formed below the head 212.

The actuating element 3 serves to lock or unlock the bearing 2 to the hinge 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. Wherein, the operation button 31 can be also provided with a button cover 311 with decoration function; the thickness of the resilient arms 33 is greater than the width of the annular groove 213; the locking piece 32 is provided with a locking hole 321. In the embodiment, the locking piece 32 is disposed above the elastic arm 33, but not limited thereto, and in another embodiment, the locking piece 32 may be disposed below the elastic arm 33.

A return spring 34 is further provided between the operation button 31 and the hinge shaft 1.

The operating 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 free end of the elastic arm 33 is provided with a hook 331 and a barb 332 adjacent to the outside, and the hook 331 or the barb 332 can be selectively matched with the limit step 121. The inner side of the resilient arm 33 is provided with a projection 333, which projection 333 is located at the inner side of the resilient arm 33, abutting the free end. Like this, when needing to dismantle the toilet lid, touch when pressing operating parts 3, operating button 31 only needs less stroke, and elastic arm 33 also only needs less deflection can make the operating parts switch to the unblock position from the lock joint position, and is little because of elastic arm 33 deflection to make the operation more laborsaving and elastic arm 33 be difficult to damage, guarantee the stability of product quality.

Furthermore, two elastic arms 33 are arranged in parallel, in a natural state, the transverse extension distance of the two hooks 331 is greater than the width of the second slot 12, the transverse extension distance of the two barbs 332 is less than the width of the second slot 12, and the elastic arms 33 and the inner wall of the second slot 12 of the hinge shaft 1 are in clearance fit.

In the locked state, the locking piece 32 and the resilient arm 33 are in the locked position. As shown in fig. 5 to 7, the hook 331 is hooked on the limit step 121 of the hinge shaft 1, and the free end of the elastic arm 33 clasps the latch 21. The edge of the locking hole 321 of the locking tab 32 is inserted into the annular groove 213 of the plug 21.

In the unlocked state, the locking tab 32 and the resilient arm 33 are in the unlocked position. As shown in fig. 14 to 16, the protrusion 333 abuts against the latch 21, the barb 332 is hooked on the limit step 121 of the hinge shaft 1, the elastic arm 33 is expanded outward and kept in an expanded state, and the edge of the locking hole 321 of the locking piece 32 is disengaged from the annular groove 213 of the latch 21.

With the above arrangement, in the initial state, the locking piece 32 and the elastic arm 33 are in the locking position, as shown in fig. 5 to 7. When the toilet cover needs to be detached from the toilet, the operating element 3 is firstly pressed, as shown in fig. 8 to 13, the protrusion 333 on the elastic arm 33 interferes with the latch 21, the elastic arm 33 deforms, the barb 332 contracts and deforms inward, when the barb 332 passes through the limit step 121 of the second slot 12, the barb 332 returns to deform, at this time, the operating button 31 is released, under the action of the return spring 34, the elastic arm 33 retracts until the protrusion 333 on the elastic arm 33 abuts against the latch 21, the two arms of the elastic arm 33 expand outward, the barb 332 retracts to the limit step 121 and hooks with the limit step 121, in this process, the edge of the lock hole 321 of the locking piece 32 leaves the annular groove 213, and the operating element 3 is switched from the locking state to the unlocking state, as shown in fig. 14 to 16. At this time, as shown in fig. 17, the hinge shaft 1 is easily separated from the holder 2 by pulling the toilet cover with one hand. The closestool cover plate is in the dismantlement in-process, need not external force and continuously presses operating parts 3, and only need the one hand to carry and pull and can easily dismantle the closestool cover plate, and this scheme structure is succinct, convenient operation, swift.

As shown in fig. 18, when the toilet lid is detached from the seat 2, the elastic arm 33 returns to its original shape under the resilience of the material, and at the same time, under the action of the return spring 34, the two barbs 332 are withdrawn from the second slot 12 and return to their original state, and the two hooks 331 are hooked with the limit step 121 again.

Above only for the explanation the utility model discloses a technical thought can not prescribe a limit to with this the utility model discloses a protection scope, all according to the utility model provides a technical thought, any improvement of doing on technical scheme basis and equal replacement all fall into the utility model discloses within the protection scope.
