Description

Technical Field

[0001] This utility model relates to the field of bathroom installation technology, specifically an installation structure for fixing the bottom of a toilet. Background Technology

[0002] The quality of toilet installation has a direct and significant impact on its performance, which is particularly evident in actual use. Traditional toilet installations typically employ a common fixing method: using specialized toilet bolts to tightly connect the bottom of the toilet to a flange on the floor. To ensure the stability of this connection, installers often use locknuts to further tighten the bolts above the toilet. However, in practice, this method often reveals a series of problems, affecting the installation quality and user experience.

[0003] Firstly, during the tightening of the nut, to prevent the nut and screw from rotating synchronously, installers must use pliers or other clamps to effectively clamp the screw. This step aims to ensure a tight connection between the nut and screw, thereby guaranteeing the stability of the connection between the toilet and the flange. However, during the clamping operation, the threads on the screw are often damaged to varying degrees due to the difficulty in precisely controlling the force and angle. This damage directly affects the locking effect between the nut and screw, making the connection less secure, which in turn affects the sealing of the drain outlet connection, potentially leading to leaks.

[0004] Secondly, when precise alignment of the mounting holes and screws at the bottom of the toilet is required, the screws are prone to misalignment under external force, making positioning difficult. This often requires installers to make repeated adjustments and attempts, which is time-consuming and labor-intensive. Due to the misalignment of the screws, the alignment accuracy between the mounting holes and the screws is difficult to guarantee. This not only prolongs the installation time but may also cause additional wear and tear on the toilet or flange due to repeated adjustments, further affecting the installation quality. This complex installation process not only increases the difficulty of the installers' work but also poses a potential threat to the long-term stability of the toilet. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an installation structure for fixing the bottom of a toilet, which enables the toilet to be quickly positioned and installed, is easy to install, and does not require the assistance of other tools, thus ensuring installation quality.

[0006] The technical solution adopted by this utility model to solve its technical problem is: An installation structure for fixing a toilet bottom includes a flange, a flange gasket, and a locking screw. It also includes a positioning screw with an internal threaded hole. The bottom of the positioning screw is slidably connected to the flange. The flange gasket is placed above the flange, and a sealing washer is placed between the flange and the flange gasket. A drain outlet sealing ring is placed above the flange gasket. The outer edge of the flange gasket has an outer edge corresponding to the position of each positioning screw, and a snap-fit ​​hole is provided on the outer edge. The flange gasket is assembled with the flange through the snap-fit ​​hole and the positioning screw. The locking screw is placed above the flange gasket and threadedly connected to the positioning screw. A nut cap is fastened to the end of the locking screw.

[0007] Compared with the prior art, the beneficial effects of this utility model are: This invention features an internal threaded hole in the positioning screw, allowing for seamless installation of the toilet through the tight fit between the positioning screw and the locking screw. This eliminates the need for additional clamps to secure the positioning screw, significantly simplifying the installation process and improving ease of use. Furthermore, the invention utilizes a snap-fit ​​structure between the flange gasket and the positioning screw to effectively limit its movement, preventing misalignment during installation. This not only ensures positioning accuracy but also greatly improves installation efficiency, making the entire installation process more stable and reliable.

[0008] As a preferred embodiment, a further technical solution of this utility model is: Preferably, the positioning screw includes a fixed section and a guide section, with the fixed section located below the guide section. Both the fixed section and the guide section are hollow structures, and internal threaded holes are provided inside the fixed section and the guide section respectively.

[0018] The flange gasket 2 is placed above the flange 1. The outer edge of the flange gasket 2 is provided with an outer edge 201 corresponding to the position of each positioning screw 3. Each outer edge 201 is provided with a strip-shaped snap-fit ​​hole 202. The two ends of the snap-fit ​​hole 202 (the two ends of the snap-fit ​​hole 202 in the length direction) are respectively fixedly connected with elastic cards 203. The ends of the two elastic cards 203 are respectively provided with arc-shaped snaps 2031. The positioning screw 3 passes through the two arc-shaped snaps 2031, and the arc-shaped snaps 2031 are snapped with the external thread structure 305 of the fixing section 302 of the positioning screw 3.

[0019] The outer edge of the fixing section 302 of the positioning screw 3 is symmetrically provided with two planes 306. On both sides of the inner wall of the snap hole 202 (the two inner walls in the width direction of the snap hole 202), limit protrusions 204 are provided on their respective planes 306. The positioning screw 3 is placed between the two limit protrusions 204. The positioning screw 3 is limited by the contact between the limit protrusions 204 and the planes 306, so as to avoid the displacement along the width direction of the snap hole 202.

[0020] In this embodiment, an annular groove 307 is also provided between the fixed section 302 and the guide section 303 of the positioning screw 3. After the toilet and the positioning screw 3 are positioned, the guide section 303 is broken off at the annular groove 307, and the locking screw 4 is threadedly connected to the fixed section 302 of the positioning screw 3.

Then, the locking block 301 of the positioning screw 3 is inserted from the wide slot end of the flange 1 and slid to the narrow slot section 1012, so that the fixing section 302 and its upper guide section 303 protrude upward from the narrow slot section 1012. Then, the sealing gasket 5 is fitted onto the bottom of the flange gasket 2, and the drain port sealing ring 6 is fitted onto the top of the flange gasket 2. The entire assembly of the three is placed on the flange 1. When installing the flange gasket 2, the snap-fit ​​hole 202 on the flange gasket 2 is aligned with the guide section 303 and then pressed down so that the flange gasket 2 is installed on the flange 1. At this time, the elastic clip 20 inside the snap-fit ​​hole 202... The external thread structure 305 of the fixing section 302 of the positioning screw 3 engages with the positioning screw 3, forming a limit on the positioning screw 3 along the length direction of the engagement hole 202, while the limiting protrusion 204 inside the engagement hole 202 limits the positioning screw 3 along the width direction of the engagement hole 202; align the toilet mounting hole with the guide section 303 of the positioning screw 3, so that the guide section 303 is quickly inserted into the mounting hole at the bottom of the toilet, then break off the guide section 303 at the annular groove 307 of the positioning screw 3, and screw the locking screw 4 into the fixing section 302 of the positioning screw 3 to complete the fixing, and finally fasten the bolt cap 7 on the outside of the nut of the locking screw 4 to complete the installation.

[0022] This invention features an internally threaded hole inside the positioning screw, allowing for seamless installation of the toilet through the close cooperation between the positioning screw and the locking screw. This eliminates the need for additional clamps to secure the positioning screw, significantly simplifying the overall installation process and improving ease of use. Furthermore, by segmenting the positioning screw and adding a guide section to increase its length, the toilet's positioning is further facilitated. Simultaneously, the snap-fit ​​mechanism between the flange gasket and the positioning screw effectively limits its movement, preventing misalignment during installation. This not only ensures positioning accuracy but also significantly improves installation efficiency, making the entire installation process more stable and reliable.

[0023] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model.
