Among them, the toilet seat cover generally includes an upper cover and a seat ring that are hinged to each other. A rotating shaft is provided on the toilet seat cover and is rotatably disposed on the toilet seat through the rotating shaft.

[0003] During the long-term use of the toilet, the toilet seat cover is prone to damage. When the toilet seat cover needs to be repaired or replaced due to damage, the toilet seat cover needs to be disassembled. Therefore, it is very necessary to achieve quick installation and disassembly between the toilet seat cover and the toilet seat. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems in the above technologies to some extent. To this end, an object of the present invention is to provide a quick-release device for a toilet seat cover, which realizes quick installation and disassembly between the toilet seat cover and the toilet seat by driving the telescopic movement of the rotating shaft.

[0005] A second object of the present invention is to provide a toilet seat cover including a quick-release device.

[0006] To achieve the above object, an embodiment of the first aspect of the present invention provides a quick-release device for a toilet seat cover, including:

[0007] A rotating member, which is rotatably disposed;

[0008] A push rod, which is axially movably disposed on the first side of the rotating member and is connected to the first connection portion of the rotating member;

When the push rod axially moves in the first direction to drive the rotation of the rotating member, the rotating member pulls the pull rod to axially move in the second direction opposite to the first direction;

[0010] An elastic member, which acts on the push rod to provide a restoring force for the push rod.

[0011] According to the quick-release device for a toilet seat cover of the embodiment of the present invention, when the push rod axially moves in the first direction to drive the rotation of the rotating member, such as when the push rod moves axially towards the pull rod, the push rod drives the rotation of the rotating member; the rotating member pulls the pull rod to axially move in the second direction opposite to the first direction, that is, the pull rod moves axially towards the push rod. At this time, the rotating shaft provided on the push rod retracts, and the toilet seat cover can be disassembled, realizing the quick disassembly of the toilet seat cover.

[0012] When the elastic member acts on the push rod, the push rod axially moves in the first direction to drive the rotating member to rotate. For example, when the push rod axially moves away from the pull rod, the push rod drives the rotating member to rotate; the rotating member pulls the pull rod to axially move in the second direction opposite to the first direction, that is, the pull rod axially moves away from the push rod. At this time, the rotating shaft provided on the push rod can extend out, enabling the toilet lid and the toilet seat to be quickly installed.

[0013] Therefore, in the present invention, through the action of the push rod on the rotating member and the rotating member on the pull rod, the rotating shaft is driven to extend or retract, realizing the quick installation and disassembly between the toilet lid and the toilet seat.

[0014] In addition, a quick-release device for a toilet lid according to the above embodiment of the present invention may further have the following additional technical features:

One end of the elastic member abuts against the fixing sleeve, and the other end of the elastic member abuts against the push rod.

[0026] To achieve the above object, a second aspect embodiment of the present invention provides a toilet lid, in which an axial mounting hole is provided, and the above-mentioned quick-release device is arranged in the axial mounting hole.

[0027] A toilet lid according to an embodiment of the present invention includes a quick-release device. When the push rod moves axially in the first direction, it drives the rotating member to rotate. For example, when the push rod moves axially towards the pull rod, the push rod drives the rotating member to rotate; the rotating member pulls the pull rod to move axially in the second direction opposite to the first direction, that is, the pull rod moves axially towards the push rod. At this time, the rotating shaft provided on the push rod retracts, and the toilet lid can be disassembled to achieve quick disassembly of the toilet lid.

[0028] When the elastic member acts on the push rod, the push rod moves axially in the first direction to drive the rotating member to rotate. For example, when the push rod moves axially away from the pull rod, the push rod drives the rotating member to rotate; the rotating member pulls the pull rod to move axially in the second direction opposite to the first direction, that is, the pull rod moves axially away from the push rod. At this time, the rotating shaft provided on the push rod extends, and the toilet lid can be connected to the toilet seat to achieve quick installation of the toilet lid.

[0029] Therefore, the present invention realizes quick installation and disassembly between the toilet lid and the toilet seat by the push rod acting on the rotating member and the rotating member acting on the pull rod to drive the rotating shaft to extend or retract. Description of the Drawings

One end of the elastic member 4 abuts against the fixing sleeve 5, and the other end of the elastic member 4 abuts against the push rod 2.

[0069] As Figure 6 and Figure 7 shown, when the quick-release device includes the fixing sleeve 5, the assembly schematic diagram with the toilet lid. An axial through hole 51 is formed in the fixing sleeve 5. The rotating member 1, the push rod 2, and the pull rod 3 are accommodated in the through hole 51. The pin shaft 13 is fixed in the fixing sleeve 5. The toilet lid 6 includes an upper lid 61 and a seat ring 62. Axial mounting holes 63 are provided on both the upper lid 61 and the seat ring 62, and the fixing sleeve 5 is installed in the axial mounting holes 63.

[0070] As Figure 9 shown, a quick-release device for a toilet lid disclosed in the second embodiment of the present invention includes a rotating member 1, a push rod 2, a pull rod 3, and an elastic member 4. The difference from the first embodiment is that:

[0071] Optionally, the push rod 2 is separately provided and includes a button 22 and a first claw 23. The button 22 is fixedly connected to the first claw 23, and a first transverse chute 21 is provided on the first claw 23. Specifically, the button 22 and the first claw 23 are fixedly connected by the cooperation of a hook and a hole. In this way, it is convenient for processing. The surface treatment can be performed on the button 22, while the surface treatment is not performed on the first claw 23, saving the processing cost.

[0072] Optionally, the pull rod 3 is separately provided and includes a connecting rod 33 and a second claw 34. The connecting rod 33 is fixedly connected to the second claw 34. A rotating shaft 32 is provided on the connecting rod 33, and a second transverse chute 31 is provided on the second claw 34. Specifically, the connecting rod 33 and the second claw 34 are fixedly connected by the cooperation of a hook and a slot. In this way, it is convenient for processing and different functions can be realized. For example, in some examples, the rotating shaft 32 can be made of a metal material.

[0073] Of course, the push rod 2 can also be separately provided, while the pull rod 3 is integrally provided, or the push rod 2 is integrally provided, while the pull rod 3 is separately provided.

[0074] In a quick-release device for a toilet lid according to an embodiment of the present invention, the push rod 2 axially moves in a first direction to drive the rotating member 1 to rotate. For example, when the push rod 2 axially moves toward the pull rod 3, the first transverse chute 21 of the push rod 2 pushes against the first slide rod 11 to drive the rotating member 1 to rotate; the rotating member 1 drives the second slide rod 12 to rotate, and the second slide rod 12 pushes against the second transverse chute 31 of the pull rod 3 to pull the pull rod 3 to axially move in a second direction opposite to the first direction, that is, the pull rod 3 axially moves toward the push rod 1. At this time, the rotating shaft 32 provided on the pull rod 3 retracts, and the toilet lid 6 can be disassembled to achieve quick disassembly of the toilet lid 6. When the elastic member 4 acts on the push rod 2, the push rod 2 axially moves in the first direction to drive the rotating member 1 to rotate. For example, when the push rod 2 axially moves away from the pull rod 3, the first transverse chute 21 of the push rod 2 pushes against the first slide rod 11 to drive the rotating member 1 to rotate; the rotating member 1 drives the second slide rod 12 to rotate, and the second slide rod 12 pushes against the second transverse chute 31 of the pull rod 3 to pull the pull rod 3 to axially move in a second direction opposite to the first direction, that is, the pull rod 3 axially moves away from the push rod 2. At this time, the rotating shaft 32 provided on the pull rod 3 extends, and the toilet lid 6 can be assembled to the toilet seat to achieve quick installation of the toilet lid 6. Therefore, in the present invention, by the push rod 2 acting on the rotating member 1 and the rotating member 1 acting on the pull rod 3, the rotating shaft 32 is driven to extend or retract, so as to achieve quick installation and disassembly between the toilet lid 6 and the toilet seat.
