[0014] The beneficial effects of this utility model are as follows: This utility model provides a toilet seat installation structure and a toilet. Compared with the prior art, this utility model has at least the following technical effects: 1. The toilet seat base is fixed by a first locking assembly and a second locking assembly to replace screw connections, achieving quick assembly and disassembly. An unlocking channel is provided to unlock both the first and second locking assemblies at once, solving the problem of low efficiency in traditional solutions that use screwdrivers to individually unscrew screws. The unlocking channel in this utility model is more concealed than the screw holes in the prior art, and the absence of screw holes in the toilet seat results in a more integrated appearance and improved aesthetics. 2. Unlocking by pushing instead of rotating screws makes operation simpler and faster, reducing operation time by more than 80%. 3. The first and second locking components can be connected using snap-fit ​​and latching mechanisms, or snap-fit ​​to snap-fit. They connect with a single press of the cover plate, making installation quick and easy. The first or second locking component is mounted on a movable limiting block. By inserting a tool into the unlocking channel and pushing the limiting block, the first and second locking components disengage, allowing for quick unlocking and removal of the cover plate base. This method is simpler and faster than unscrewing multiple screws one by one. 4. A guide component guides the movement of the limiting block, and a first reset component drives the limiting block to reset along the guide direction, ensuring precise alignment between the limiting block and the unlocking channel and guaranteeing a high success rate for unlocking. 5. A limiting pin is also provided to block the movement path of the limiting block. When the tool drives the limiting block to move and unlock, the limiting pin slides out to prevent the limiting block from resetting and locking, maintaining a stable unlocked state without requiring continuous tool operation, making the removal of the cover plate base even more convenient. 6. Driven by the second reset component, the limiting pin abuts against the limiting block in the installed state. When the limiting block is pushed away, the limiting pin, no longer obstructed, extends into the movement path of the limiting block to prevent the limiting block from being driven to reset by the first reset component, thus maintaining the stability of the unlocked state. 7. The unlocking channel includes a disassembly hole and a clearance channel. A tool is inserted into the disassembly hole and then into the clearance channel to accurately push the limiting block, thus unlocking the toilet. The decorative cover conceals the disassembly hole in the normal use state of the toilet, maintaining aesthetics. Unlocking the connection between the toilet seat and the toilet body by inserting a tool into the disassembly hole prevents children from accidentally touching it, thus preventing accidental removal of the toilet seat. 8. A bracket is provided to install the first locking assembly, etc. The material of the first locking assembly can be different from that of the toilet body to facilitate its production and processing. The bracket and the seat base have corresponding positioning posts and positioning holes, allowing the first and second locking assemblies to be accurately aligned and locked. 9. The design of the guide post and guide hole facilitates the alignment and installation of the seat base with the toilet body. At the same time, the conical design enables the seat base and the toilet body to automatically align, thereby ensuring that the first locking assembly and the second locking assembly can lock accurately.

The seat base 2 is fixed by locking the first locking assembly and the second locking assembly, replacing screw connections, achieving quick installation. The unlocking channel unlocks the engagement of the first locking assembly and the second locking assembly at once, solving the problem of low efficiency in traditional solutions that use screwdrivers to individually unscrew screws. The absence of screw holes in the seat results in a more integrated and aesthetically pleasing appearance. The seat base 2 generally refers to the part of the seat that is mounted on the toilet body 1 and can be detachably and fixedly connected to the toilet body 1 by a locking assembly.

[0029] Please see Figures 1 to 10 Preferably, the first locking assembly includes a first locking member 4, and the second locking assembly includes a second locking member 5. The first locking member 4 and the second locking member 5 can be engaged with each other, and at least one of the first locking member 4 and the second locking member 5 can move relative to the toilet body 1. The unlocking channel allows a tool to be inserted to push the first locking member 4 and / or the second locking member 5 to move in a preset direction to unlock. Unlocking by pushing instead of rotating the screw is simpler and faster, reducing operation time by more than 80%. In this embodiment, the first locking member 4 is fixed to the toilet body 1, and the second locking member 5 can be movably installed on the seat base 2.

[0030] Please see Figures 1 to 10Preferably, the first locking component 4 is a first limiting buckle, and the second locking component 5 is a second limiting buckle or buckle opening. The first limiting buckle is engaged with the second limiting buckle or the buckle opening. The first locking assembly also includes a limiting block 6, which is movably installed in the toilet body 1. The first limiting buckle is fixed to the limiting block 6. The unlocking channel insertion tool pushes the limiting block 6 to move, thereby driving the first limiting buckle to disengage from the second limiting buckle or buckle opening in a preset direction to achieve unlocking. Alternatively, the first locking component 4 is a first limiting buckle or buckle opening, and the second locking component 5 is a second limiting buckle. The second limiting buckle is engaged with the first limiting buckle or buckle opening. The second locking assembly also includes a limiting block 6, which is movably installed in the lid base 2. The second limiting buckle is installed in the limiting block 6. The unlocking channel insertion tool pushes the limiting block 6 to move, thereby driving the second limiting buckle to disengage from the first limiting buckle or buckle opening in a preset direction to achieve unlocking. The first and second locking components can be fastened using snap-fit ​​and latching, or snap-fit ​​to snap-fit, allowing for quick and easy installation with a single press. The first locking component 4 or the second locking component 5 is mounted on a movable limiting block 6. By inserting a tool into the unlocking channel and pushing the limiting block 6, the first locking component 4 and the second locking component 5 can be disengaged, allowing for quick unlocking and removal of the cover plate base 2. This disassembly method is simpler and faster than tightening multiple screws one by one. In this embodiment, the first locking component 4 is a first limiting buckle, and the second locking component 5 is a second limiting buckle. The first limiting buckle and the second limiting buckle are fastened together. The second locking component also includes a limiting block 6, which is movably installed in the cover plate base 2. The second limiting buckle is fixed to the limiting block 6. The tool inserted into the unlocking channel pushes the limiting block 6 to move, thereby driving the second limiting buckle to disengage from the first limiting buckle and unlocking the cover plate base 2.

[0031] Please see Figures 1 to 4 , Figures 7 to 10Preferably, the device further includes a guide member 7, on which the limiting block 6 is slidably or oscillatingly mounted. A first reset member 8 is provided between the guide member 7 and the limiting block 6 to drive the limiting block 6 to reset in the direction opposite to the unlocking direction. If the limiting block 6 is located in the first locking assembly, the guide member 7 is fixed to the toilet body 1; if the limiting block is located in the second locking assembly, the guide member 7 is fixed to the seat base 2. The guide member 7 guides the movement of the limiting block 6, and the first reset member 8 drives the limiting block 6 to reset along the guiding direction of the guide member 7, ensuring that the limiting block 6 can be precisely aligned with the unlocking channel and ensuring the success rate of the unlocking operation. In this embodiment, the guide member 7 is part of the second locking assembly. The guide member 7 is a guide block with a telescopic cavity. The limiting block 6 is slidably installed in the telescopic cavity. The first reset member 8 can be an elastic element such as a spring or rubber, and is installed in the telescopic cavity. The second locking member 5 is preferably a second limiting buckle, which is fixed to the lower surface of the limiting block 6. The side wall of the telescopic cavity also has a clearance groove to allow the second limiting buckle to move. The first locking member 4 is preferably a first limiting buckle, and the hooking directions of the two limiting buckles are opposite. Preferably, there are two or more first and second limiting buckles, which are arranged parallel to each other at equal intervals. The distance between two adjacent first limiting buckles should be greater than or equal to the minimum disengagement distance.

[0032] Please see Figures 1 to 4 , Figures 7 to 10 Preferably, the assembly also includes a limiting pin 9, which blocks the movement path of the limiting block 6. The movement paths of the limiting pin 9 and the limiting block 6 intersect, preventing the limiting block 6 from resetting after unlocking. If the limiting block 6 is located in the first locking assembly, the limiting pin 9 is slidably mounted on the toilet seat base 2; if the limiting block 6 is located in the second locking assembly, the limiting pin 9 is slidably mounted on the toilet body 1. The limiting pin 9 blocks the movement path of the limiting block 6. When the tool drives the limiting block 6 to move and unlock, the limiting pin 9 slides out to prevent the limiting block 6 from resetting and locking, maintaining a stable unlocked state without requiring continuous tool operation, making the removal of the toilet seat base more convenient. In this embodiment, the first locking assembly also includes a limiting pin 9, which is slidably mounted on the toilet body 1.

[0033] Please see Figures 1 to 4 , Figures 7 to 10Preferably, when the limiting pin 9 is slidably installed on the toilet body 1, a second reset member 10 is connected between the limiting pin 9 and the toilet body 1. When the limiting pin 9 is slidably installed on the lid base 2, a second reset member 10 is connected between the limiting pin 9 and the lid base 2. The sliding direction of the limiting pin 9 is perpendicular to the preset activity direction of the limiting block 6. The second reset member 10 is used to drive the limiting pin 9 to extend. The limiting pin 9 is located at the end of the limiting block 6 away from the first reset member 8. When the first locking member 4 and the second locking member 5 are engaged, the limiting pin 9 is blocked by the limiting block 6. When the limiting block 6 is unlocked by external force, the limiting pin 9 is driven by the second reset member 10 to extend and block the reset path of the limiting block 6. Under the drive of the second reset member 10, the limiting pin 9 abuts against the limiting block 6 in the installed state. When the limiting block 6 is pushed away, the limiting pin 9, no longer obstructed, extends into the movement path of the limiting block 6 to prevent the limiting block 6 from being driven to reset by the first reset member 8, thus maintaining the stability of the unlocked state. The second reset member 10 can be an elastic element such as a spring or rubber, and is not limited thereto.

[0034] Please see Figures 1 to 5 Preferably, the unlocking channel includes a disassembly hole 17 and a clearance channel 3. The disassembly hole 17 is located in the toilet body 1 and / or the seat base 2. A clearance channel is provided between the disassembly hole 17 and the first locking assembly and / or the second locking assembly. A tool extends through the disassembly hole into the clearance channel to unlock the first locking assembly and / or the second locking assembly. A decorative cover 11 is provided at the disassembly hole 17, which can be opened and closed. The unlocking channel is a disassembly hole located in the toilet body 1 and / or the seat base 2. When a tool is inserted into the disassembly hole 17, it can accurately push the limiting block 6 to unlock the toilet. The decorative cover 11 covers the disassembly hole 17 in the normal use state of the toilet to maintain aesthetics. By inserting a tool into the disassembly hole 17, the unlocking seat and toilet body are less likely to be accidentally touched by children, thus preventing accidental removal of the toilet seat. In this embodiment, the disassembly hole 17 is provided on the cover plate base 2, and the clearance channel 3 is provided on the cover plate. The tool is inserted into the disassembly hole 17 to drive the limiting block 6 of the second latching assembly to move and unlock.

[0035] Please see Figures 1 to 10Preferably, the toilet also includes a bracket 12, which is fixed to the toilet body 1, and the first locking assembly is installed on the bracket 12. The bracket 12 has a positioning post 13, and the corresponding position of the lid base 2 has a positioning hole 14; or, the bracket 12 has a positioning hole 14, and the corresponding position of the lid base 2 has a positioning post 13; the positioning post 13 passes through the positioning hole 14. The bracket 12 is used to install the first locking assembly, etc. The material of the first locking assembly is different from that of the toilet body 1, which facilitates its production and processing. The bracket 12 and the lid base 2 have corresponding positioning posts 13 and positioning holes 14, so that the first locking assembly and the second locking assembly can be accurately aligned to achieve locking. The first limiting buckle is fixed to the bracket 12. Preferably, the limiting pin 9 is slidably installed on the bracket 12, and the bracket 12 has a guide telescopic hole, in which the limiting pin 9 is installed, and the second reset member 10 is installed in the telescopic guide hole 15.

The design of the guide posts 16 and guide holes 15 facilitates the alignment and installation of the seat base 2 and the toilet body 1, while the conical design enables the seat base 2 and the toilet body 1 to automatically align, ensuring that the positioning post 13 can accurately pass through the positioning hole 14, thereby ensuring that the first locking assembly and the second locking assembly can accurately lock.

[0037] Please see Figure 11 A toilet is provided with a seat mounting structure as described in any of the above claims. The seat base 2 is secured by a first locking assembly and a second locking assembly, replacing screw connections and enabling tool-free, quick installation. An unlocking channel is provided to unlock both the first and second locking assemblies at once, solving the problem of low efficiency in traditional solutions that require screwdrivers to individually unscrew screws. The absence of screw holes in the seat enhances its overall appearance and improves its aesthetics.

[0038] The working principle of this utility model is as follows:

[0039] During installation, align the guide hole 15 with the guide post 16, then press down on the seat base 2. The positioning post 13 will pass into the positioning hole 14, ensuring that the first locking member 4 and the second locking member 5 are in the correct positions. At this time, the limiting block 6 is kept in the pushed-out state by the action of the first reset member 8. The lower surface of the limiting block 6 will abut against the extended limiting pin 9. Then, continue to press down on the seat base 2. The limiting pin 9 will be pushed down by the limiting block 6. The first locking member 4 and the second locking member 5 will come into contact and abut against each other, resulting in elastic deformation. As the seat base 2 continues to descend, the first locking member 4 and the second locking member 5 will be reshaped and hooked together by their own force, thus completing the fixed connection between the seat base 2 and the toilet body 1.

[0040] During disassembly, remove the decorative cover 11, insert a tool (such as a screwdriver or other rod-shaped object) into the disassembly hole 17, and push the limiting block 6 back into the guide member 7. The limiting pin 9, no longer blocked by the limiting block 6, extends to the sliding path of the limiting block under the force of the second reset member 10. After the tool is removed, the limiting block 6 is blocked by the limiting pin 9 and cannot extend, so that the distance between the first locking member 4 (first limiting buckle) and the second locking member 5 (second limiting buckle) is kept in the disengaged position. In this way, the seat base 2 can be removed from the toilet body 1.

[0041] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
