[0005] A quick-release structure for a toilet seat includes an anti-rotation shaft fixed to the toilet seat body and a child seat sleeve connected to the anti-rotation shaft. The anti-rotation shaft includes a first rotating shaft end and an anti-rotation shaft body, which are fixedly connected. The anti-rotation shaft and the child seat sleeve are rotatably engaged through a rotating shaft connector. The child seat sleeve has a receiving cavity, and the rotating shaft connector is sleeved in the receiving cavity and rotates relative to the child seat sleeve. The rotating shaft connector has a first notch on one side relative to the first rotating shaft end, and the first rotating shaft end is embedded in the first notch and circumferentially limited by the first notch. The child seat sleeve has a second notch. When the child seat sleeve is rotated until the first notch and the second notch are aligned, the first notch and the second notch communicate, and the first rotating shaft end can detach from the first notch.

[0006] The present invention is further configured such that a snap-fit ​​structure is provided between the first shaft end and the first notch.

[0007] The present invention is further configured such that: the snap-fit ​​structure includes a first snap-fit ​​rib protruding from one of the side wall of the first rotating shaft end and the inner wall of the first notch, and also includes a first limiting groove provided on the other of the side wall of the first rotating shaft end and the inner wall of the first notch; when the first rotating shaft end is installed in place, the first snap-fit ​​rib is snapped into the first limiting groove for snap-fit ​​engagement.

[0008] The present invention is further configured such that: the first shaft end is a rectangular protrusion protruding from one end of the shaft body relative to the shaft connector, the first notch is a rectangular groove matching the rectangular protrusion, and the side wall of the first shaft end fits against the inner wall of the first notch.

[0009] The present invention is further configured such that: a decelerator is provided in the accommodating cavity, the decelerator includes a decelerator shaft and a decelerator housing that rotate relative to each other, the decelerator shaft is circumferentially limited to a shaft connector, and the decelerator housing is circumferentially limited to a child seat ring bushing.

[0010] The present invention is further configured such that: the rotating shaft connector is provided with a connecting groove on one side of the decelerator rotating shaft; the decelerator rotating shaft is provided with a second rotating shaft end that cooperates with the connecting groove; a second snap-fit ​​rib protrudes from one of the inner wall of the connecting groove and the side wall of the second rotating shaft end; a second limiting groove is provided on the other of the inner wall of the connecting groove and the side wall of the second rotating shaft end; when the second rotating shaft end of the decelerator rotating shaft is inserted into the connecting groove of the rotating shaft connector, the second snap-fit ​​rib is inserted into the second limiting groove for snap-fit ​​engagement.

[0011] The present invention is further configured such that: the decelerator housing is sleeved in the accommodating cavity, a third snap-fit ​​rib protrudes from one of the side wall of the decelerator housing and the inner wall of the accommodating cavity, and a third limiting groove is provided on the other of the side wall of the decelerator housing and the inner wall of the accommodating cavity, and the third snap-fit ​​rib passes into the third limiting groove for snap-fit ​​engagement.

[0012] The present invention is further configured such that: both the left and right ends of the child seat ring bushing are provided with rotating shaft connectors, and the rotating shaft connectors respectively cooperate with the first rotating shaft end of the corresponding anti-rotation shaft.

[0013] The present invention is further configured such that: the anti-rotation shaft is fixedly installed on the toilet seat body by a fixing seat, and the anti-rotation shaft body is rotatably engaged with the adult seat ring bushing and / or the toilet seat bushing.

[0014] The present invention is further configured such that: the toilet seat is located at the end of the adult seat ring sleeve away from the child seat ring sleeve and is rotatably connected to the adult seat ring sleeve; the anti-rotation shaft body is rotatably engaged with the adult seat ring sleeve; and the toilet seat and the adult seat ring sleeve are rotatably connected by a slow-closing device.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] 1. The child seat ring is rotatably connected to the anti-rotation shaft via a rotating shaft connector. When the child seat ring bushing rotates, it drives the decelerator housing to rotate around the decelerator shaft. The decelerator shaft and the rotating shaft connector remain stationary under the circumferential limiting action of the anti-rotation shaft. Therefore, when the child seat ring bushing rotates to a preset angle, the first notch can be aligned with the second notch, and the shaft end can sequentially disengage from the first notch and the second notch, thereby allowing the child seat ring to be removed from the anti-rotation shaft, achieving a quick-release function and meeting usage requirements.

[0017] 2. The shaft end is a rectangular protrusion, which is embedded in the corresponding first notch to achieve circumferential positioning with the shaft connector. The two are connected by a first snap-fit ​​rib and a first limiting groove, so that the shaft end and the first notch are interference fit, making it difficult for the shaft end to fall out of the first notch and improving the connection stability.

[0018] 3. By installing a damper in the accommodating cavity, the seat ring generates a damping effect when rotating, preventing the seat ring from slipping off automatically, reducing impact, and extending service life. Attached Figure Description

[0028] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] A quick-release structure for toilet seat rings, such as Figure 1 and Figure 2 As shown, the toilet includes an anti-rotation shaft fixed to the toilet seat body 1 and a child seat sleeve connected to the anti-rotation shaft. The anti-rotation shaft includes a first rotating shaft end 6 and an anti-rotation shaft body 5, which are fixedly connected. The anti-rotation shaft and the child seat sleeve are rotatably engaged through a rotating shaft connector 7. The child seat sleeve is provided with a receiving cavity 8. Both the receiving cavity 8 and the rotating shaft connector 7 are cylindrical in shape. The rotating shaft connector 7 and the receiving cavity 8 are coaxially arranged. The rotating shaft connector 7 is sleeved in the receiving cavity 8 and rotates relative to the child seat sleeve, so that the child seat 2 can rotate around the rotating shaft connector 7.

[0030] The rotating shaft connector 7 has a first notch 9 communicating with the receiving cavity 8 on one side relative to the first rotating shaft end 6. The first notch 9 is opened radially inward from the peripheral sidewall of the rotating shaft connector 7. The first rotating shaft end 6 is embedded in the first notch 9 and is circumferentially limited by the first notch 9, so that the first rotating shaft end 6 will not rotate relative to the first notch 9. The child seat bushing has a second notch 10 communicating with the receiving cavity 8. The second notch 10 is opened radially inward from the peripheral sidewall of the child seat bushing, so that the receiving cavity 8 communicates with the outside. When the child seat bushing is rotated until the first notch 9 and the second notch 10 are aligned, the first notch 9 and the second notch 10 communicate, and the first rotating shaft end 6 can be disengaged from the first notch 9, so that the child seat 2 can be removed.

[0031] like Figures 3 to 6 As shown, in this embodiment, the first rotating shaft end 6 is a rectangular protrusion protruding from one end of the rotating shaft body 5 relative to the rotating shaft connector 7. The rectangular protrusion is integrally formed with the rotating shaft body 5. The first notch 9 is a rectangular groove that matches the rectangular protrusion. When the first rotating shaft end 6 is inserted into the first notch 9, the side wall of the first rotating shaft end 6 fits against the inner wall of the first notch 9 to prevent shaking.

[0032] A snap-fit ​​structure is provided between the first shaft end 6 and the first notch 9. The snap-fit ​​structure includes a first snap-fit ​​rib 11 protruding from either the side wall of the first shaft end 6 or the inner wall of the first notch 9, and a first limiting groove 12 provided on the other side wall of the first shaft end 6 or the inner wall of the first notch 9. When the first shaft end 6 is installed in place, the first snap-fit ​​rib 11 snaps into the first limiting groove 12 for engagement. In this embodiment, the first snap-fit ​​rib 11 protrudes from the side wall of the first shaft end 6, and the first limiting groove 12 is provided on the inner wall of the first notch 9. When the first shaft end 6 is inserted into the first notch 9, the first snap-fit ​​rib 11 is inserted into the first limiting groove 12 for engagement. The first snap-fit ​​rib 11 and the first limiting groove 12 achieve an interference fit between the first shaft end 6 and the shaft connector 7, making it less likely for the first shaft end 6 to fall out of the first notch 9 and improving connection stability. The surface of the first snap-fit ​​rib 11 is arc-shaped. The user can directly insert the first shaft end 6 into the first notch 9 by applying external force, or directly pull it out.

[0033] A decelerator is installed within the accommodating cavity 8. The decelerator includes a decelerator shaft 13 and a decelerator housing 14 that rotate relative to each other. The decelerator shaft 13 is circumferentially limited by a shaft connector 7, and the decelerator housing 14 is circumferentially limited by a child seat ring bushing. When the child seat ring 2 rotates, it will cause the decelerator housing 14 to rotate around the decelerator shaft 13, thereby producing a damping effect. While the child seat ring 2 and the decelerator housing 14 rotate, the decelerator shaft 13, the shaft connector 7, and the anti-rotation shaft remain stationary.

[0034] A connecting groove 18 is provided on one side of the decelerator shaft 13 relative to the shaft 13. The decelerator shaft 13 has a second shaft end 19 that mates with the connecting groove 18. The second shaft end 19 is a non-circular cylindrical shape that protrudes from one end of the decelerator housing 14. The second shaft end 19 passes into the connecting groove 18 to achieve circumferential limiting. A second snap-fit ​​rib protrudes from one of the inner wall of the connecting groove 18 and the side wall of the second shaft end 19. A second limiting groove 15 is provided on the other of the inner wall of the connecting groove 18 and the side wall of the second shaft end 19. When the second shaft end 19 of the decelerator shaft 13 passes into the connecting groove 18 of the connecting shaft connector 7, the second snap-fit ​​rib passes into the second limiting groove 15 and engages.

[0035] In this embodiment, a second snap-fit ​​rib protrudes from the inner wall of the connecting groove 18, and a second limiting groove 15 is provided on the side wall of the second rotating shaft end 19. When the second rotating shaft end 19 is inserted into the connecting groove 18, the second snap-fit ​​rib is inserted into the second limiting groove 15 for snap-fit ​​engagement. The interference fit further improves the stability between the decelerator rotating shaft 13 and the rotating shaft connector 7, preventing accidental detachment.

[0036] The decelerator housing 14 is cylindrical in shape and is coaxially arranged with the receiving cavity 8. The decelerator housing 14 is fitted inside the receiving cavity 8. A third snap-fit ​​rib 16 protrudes from one of the side wall of the decelerator housing 14 and the inner wall of the receiving cavity 8. A third limiting groove is provided on the other side wall of the decelerator housing 14 and the inner wall of the receiving cavity 8. The third snap-fit ​​rib 16 passes into the third limiting groove and engages with it.

[0037] In this embodiment, a third snap-fit ​​rib 16 protrudes from the side wall of the descent control housing 14, and a third limiting groove is provided on the inner wall of the accommodating cavity 8. The third snap-fit ​​rib 16 passes into the third limiting groove for snap-fit ​​engagement. The interference fit achieves circumferential limiting between the descent control housing 14 and the child seat ring 2 bushing, allowing them to rotate synchronously.

[0038] In this embodiment, the left and right ends of the child seat ring 2 bushing are provided with rotating shaft connectors 7, and the left and right ends of the toilet seat body 1 are provided with anti-rotation shafts. The rotating shaft connectors 7 are respectively engaged with the first rotating shaft end 6 of the corresponding anti-rotation shaft.

[0039] The anti-rotation shaft is fixedly installed on the toilet seat 1 via the fixing seat 17. The anti-rotation shaft body 5 is rotatably engaged with the adult seat ring 3 bushing and the toilet seat 4 bushing, and the adult seat ring 3 and the toilet seat 4 can rotate around the anti-rotation shaft body 5.

[0040] The toilet seat 4 is located at the end of the adult seat ring bushing furthest from the child seat ring bushing and is rotatably connected to the adult seat ring bushing. The anti-rotation shaft body 5 is rotatably engaged with the adult seat ring bushing. The toilet seat 4 and the adult seat ring bushing are rotatably connected via a soft-close mechanism. The child seat ring bushing is integrally formed with the child seat ring 2, the adult seat ring bushing is integrally formed with the adult seat ring 3, and the toilet seat bushing is integrally formed with the toilet seat 4.

[0041] The working process of this utility model is as follows:

[0042] When it is necessary to remove the child seat ring 2, rotate the child seat ring 2. The second notch 10 will change its orientation as the child seat ring 2 rotates. When the child seat ring 2 is rotated to the set angle, the second notch 10 is aligned with the first notch 9. At this time, apply external force to pull the child seat ring 2 radially outward along the receiving cavity 8, so that the first rotating shaft end 6 is moved out of the receiving cavity 8, and the child seat ring 2 can be removed. During installation, align the second notch 10 with the first notch 9 first, and then insert the first rotating shaft end 6.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
