[0032] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1 — Figure 3 :

[0033] A connecting device for a toilet cover includes a mounting base 1, an adjustment mounting hole 2 is provided on the mounting base 1, a hole adjustment member 3 is embedded in the adjustment mounting hole 2, and the hole adjustment member 3 can rotate freely in the horizontal direction within the adjustment mounting hole 2, the hole adjustment member 3 is provided with a strip mounting hole 30 for matching with a bolt, the upper end cover of the adjustment mounting hole 2 is provided with a sealing cover 4, and the mounting base 1 is provided with a hinge mechanism 5 for installing a toilet ring and a toilet cover.

[0034] During the specific implementation, the mounting base is placed over the bolt holes on the edge of the toilet bowl, and the hole adjustment member is placed within the adjustment hole. The strip-shaped mounting hole 30 is then rotated to align the bolt holes. Furthermore, during the installation process, both connecting devices, i.e., the bolt holes on both sides, must be aligned before installation. Finally, the sealing cover 4 is buckled to protect the bolt positions, ensuring waterproof and durable operation.

[0035] It is worth mentioning that since it is a strip-shaped mounting hole 30, in order to prevent the mounting base 1 from rotating around the bolt, resulting in misalignment or poor stability, two bolts are installed in the strip-shaped mounting hole 30, and there need to be two bolt holes at the corresponding position of the toilet bowl.

[0036] Preferably, the hinge mechanism 5 includes a main rod 50, and the two ends of the main rod 50 are respectively hinged with a first hinged connecting rod 51 for fixing the bottom of the toilet cover and a second hinged connecting rod 52 for fixing the bottom of the toilet ring. The lower end of the main rod 50 is provided with a plug-in column 53, and the mounting base 1 is provided with a rotating hole 6 for the plug-in column 53 to be plugged in and rotated.

[0037] In the above structure, the hinge mechanism is installed on the mounting base in a plug-in manner, which not only facilitates installation but also enables the replacement and disassembly of the toilet lid assembly, greatly improving convenience.

[0038] During the installation process, the toilet lid is fixed at the end of the first hinged link by bolts or clamping. Similarly, the second hinged link fixes the end of the toilet ring in the same way, thereby realizing independent hinged opening of the toilet lid and the toilet ring.

[0039] Preferably, an abutment hole 60 is provided on the hole wall of the rotating hole 6, and an abutment ball 61 with a spring at one end is provided in the abutment hole 60, and the spring drives the abutment ball 61 to move in the axial direction of the abutment hole 60, and an annular groove 54 is provided on the side wall of the plug-in column 53 for abutting the outer wall of the abutment ball 61.

[0040] In the above structure, the matching abutment ball 61 and the annular groove 54 can prevent the hinge mechanism from falling off after being plugged in.

[0041] Preferably, there are two abutment holes 60, which are arranged opposite to each other on both sides of the rotation hole 6, so as to improve the stability during abutment.

[0042] Preferably, a limiting convex ring 20 is formed in the adjustment installation hole 2, and the lower end surface of the hole position adjustment member 3 abuts against the upper end surface of the limiting convex ring 20, so as to facilitate the installation of the hole position adjustment member.

[0043] Preferably, the outer edge of the bottom of the hole adjustment member 3 is provided with a plurality of circumferentially distributed abutment protrusions 31 that abut against the upper end surface of the limiting protrusion 20. The provision of the abutment protrusions 32 can create a certain gap between the hole adjustment member 3 and the limiting protrusion 20, reducing friction and allowing the hole adjustment member 3 to rotate smoothly during calibration.

[0044] Preferably, the upper edge of the strip-shaped mounting hole 30 is provided with a plurality of anti-slip protrusions 32 for abutting against the ends of the bolts.

[0045] Preferably, a non-slip rubber pad 7 is provided at the bottom of the mounting base 1, and a through hole corresponding to the adjustment mounting hole 2 is opened on the non-slip rubber pad 7. When installed, the mounting base 1 will not slip at the toilet bowl opening.

[0046] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
