Description

Technical Field

[0001] This invention relates to the field of bathroom installation technology, specifically a quick-release toilet foot fixing bolt. Background Technology

[0002] Currently, the installation and fixing of toilets in the bathroom industry, especially the connection between the base and the flange, generally adopts the traditional bolt and nut fastening method. However, in actual installation, use and maintenance, this method has the following technical defects: First, the limited space for installation and operation leads to low efficiency: After the toilet is installed, the gap between its base and the ground or wall is extremely narrow. When using traditional tools such as wrenches and sockets to tighten or disassemble bolts, the operating space is severely insufficient, making it difficult to apply tightening torque. The installation process is time-consuming and laborious, especially difficult for a single person to operate, with an average installation time of 10-15 minutes. Secondly, the later maintenance and disassembly are difficult: when the toilet needs to be moved, replaced or repaired, the bolts need to be loosened in the opposite direction in the same small space. Due to the long-term influence of the humid environment, the bolts are very prone to rust, thread seizing, or tool slippage, which leads to disassembly failure or even forced destructive disassembly, increasing maintenance costs and user inconvenience. Third, the uncontrollable tightening state can easily lead to secondary problems: when tightening traditional bolts manually with tools, it is impossible to accurately control the axial locking force. Excessive tightening torque can cause the ceramic toilet base or flange to crack; insufficient tightening torque can not effectively compress the sealing gasket, and after long-term use, problems such as toilet shaking, flange seal failure, water leakage and odor may occur, which seriously affect the user experience and hygiene.

[0003] Finally, the components are scattered and easily lost: nuts, flat washers, spring washers, etc. in traditional bolt assemblies are independent small parts that are easy to slip from the operator's hands during installation or disassembly and fall into pipes or ground gaps, which not only affects installation efficiency but also brings safety hazards.

[0004] To address the aforementioned issues, some existing technologies have proposed improved solutions such as quick-release or tool-free fixing, for example, using spring-loaded or manual wrench-type locking structures. However, these solutions still have significant shortcomings: Poor reliability: The spring-loaded clamping structure is prone to fatigue failure after long-term use, resulting in a decrease in locking force and an inability to provide durable anti-loosening performance; Insufficient sealing performance: It lacks effective axial pressure buffering and sealing components, making it difficult to adapt to the flatness and height tolerances of toilet flanges during actual installation.

[0005] In summary, there is an urgent need for a toilet foot fixing bolt that requires no special tools, is suitable for confined spaces, and can provide a stable and adjustable locking force to solve the problems of low installation efficiency, difficult maintenance, uncontrollable tightening state, and poor sealing in existing technologies. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a quick-release toilet foot fixing bolt that can be tightened and locked with one hand without the need for special tools, is suitable for narrow installation spaces, and can effectively improve installation and maintenance efficiency.

[0007] The technical solution adopted by this invention to solve its technical problem is: A quick-release toilet base fixing bolt includes a positioning nut, a screw assembly, and a cap, as well as a pressure-bearing sealing assembly and a quick-locking assembly. The positioning nut is adapted to the toilet flange mounting groove; the screw assembly includes a rod head and a rod body, with the rod body threadedly connected to the positioning nut; the pressure-bearing sealing assembly is sleeved on the outside of the rod body and is used to abut against the toilet base and flange; the quick-release locking assembly includes a rocker arm and a pin, with the rocker arm hinged to the rod head via the pin, and the rocker arm rotating around the pin axis between an unlocked position and a locked position.

[0008] Compared with the prior art, the beneficial effects of the present invention are: This invention features a simple and robust structure, preventing items from being scattered or lost during installation. It eliminates the need for traditional tools like wrenches and sockets, allowing for single-person, one-handed operation throughout the process, significantly reducing installation time. Maintenance and replacement are extremely convenient; there's no need to worry about rust or tool slippage during relocation or repair. Simply move the rocker arm and unscrew the screw in the opposite direction for quick disassembly, greatly reducing maintenance difficulty and cost. Furthermore, this fixing bolt is perfectly suited for confined spaces; the screw assembly can be freely rotated by hand in the unlocked state, eliminating the need for tool access and solving the problem of tools being unable to enter due to narrow gaps between the toilet base and walls or floors. The pressure-bearing sealing component and quick-release locking component provide reliable sealing, preventing toilet shaking, leaks, and odors.

[0009] As a preferred embodiment, a further technical solution of the present invention is: Preferably, the positioning nut is a T-nut, and the positioning nut has internal threads that are compatible with the rod body.

[0010] Preferably, the pressure-bearing sealing assembly includes, from bottom to top, a cap gasket, a metal washer, and a rubber gasket, with the rocker arm pressing directly against the rubber gasket in the locked state.

[0011] Preferably, when the rocker arm rotates from the unlocked position to the locked position around the pin, the distance between the contact point between the rocker arm and the rubber washer and the center of rotation gradually increases, generating a clamping force downward along the screw axis.

[0012] Preferably, the cap pad has an outer edge, the upper surface of which is inclined, and an annular groove is provided on the inner wall of the cap near its lower edge. The cap pad is engaged with the cap by the cooperation of the outer edge and the groove.

[0013] Preferably, the cap pad has an elongated hole, and the metal washer and the rubber washer each have a round hole that fits the rod body.

[0014] Preferably, the contact point between the rocker arm and the rubber gasket is set to a rough surface, which is one or a combination of knurled surface, textured surface, sandblasted surface or fine toothed surface. Attached Figure Description

[0018] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0019] like Figures 1 to 5 As shown, a quick-release toilet foot fixing bolt consists of a positioning nut 1, a screw assembly 2, a cap 3, a pressure-bearing sealing assembly 4, and a quick-locking assembly 5.

[0020] The positioning nut 1 has internal threads and is a T-shaped nut. The positioning nut 1 is adapted to the mounting groove of the toilet flange. During installation, the bottom of the nut is inserted horizontally into the flange groove and then rotated 90 degrees. The anti-rotation positioning is achieved by using the slot 301 to prevent the nut from rotating freely when the screw is tightened laterally (the T-shaped nut and flange clamping structure is existing technology, and the specific details are not described in detail here).

[0021] The screw assembly 2 consists of a screw head 201 and a screw body 202. The screw head 201 is placed on top of the screw body 202. The screw body 202 is made of fine-pitch screw and is threadedly connected to the positioning nut 1. The lower end of the screw body 202 is inserted into the positioning nut 1, and axial feed motion is achieved by rotation.

[0022] The pressure-bearing sealing component 4 is sleeved on the outside of the rod body 202 and is used to abut against the toilet base and the flange. Specifically, the pressure-bearing sealing component 4 consists of a cap gasket 401, a metal washer 402 and a rubber washer 403. The cap gasket 401 has an elongated hole, and the metal washer 402 and the rubber washer 403 have round holes that fit the rod body 202. The cap gasket 401, the metal washer 402 and the rubber washer 403 are sleeved on the rod body 202 from bottom to top.

[0023] The quick-release locking assembly consists of a rocker arm 501 and a pin 502. The rocker arm 501 has a U-shaped structure and is fitted around the outside of the rod head 201, connected to the pin 502 that passes through the rod head 201. The rocker arm 501 is hinged to the rod head 201 via the pin 502. The rocker arm 501 rotates between the unlocked and locked positions, specifically as follows: Figure 2 As shown, when the rocker arm 501 is approximately parallel to the axis of the lever 202 and flipped upwards, the rocker arm 501 is in the unlocked position, as... Figure 3 As shown, when the rocker arm 501 is approximately perpendicular to the screw axis, the rocker arm 501 is in the locked position, and in the locked position, the rocker arm 501 is directly pressed against the rubber washer 403.

[0024] The lower surface of the rocker arm 501 is set as an eccentric cam surface 7. The eccentric cam surface 7 is rotated around the axis of the pin 502. When the rocker arm 501 rotates about 90° around the pin 502 from the unlocked position to the locked position, the contact point between the rocker arm 501 and the rubber washer 403 gradually slides to a position far away from the rotation center. As the distance between the contact point and the rotation center gradually increases, this distance increment is converted into a pressing displacement along the axial direction of the rod 202, thereby generating a pressing force to press the rubber washer 403 downward.

[0025] The cap 401 is used to contact the surface of the toilet base. The elongated hole on the cap 401 allows the cap 401 to be laterally displaced relative to the rod 202 along the extension direction of the elongated hole to accommodate the installation deviation between the mounting hole on the toilet base and the rod 202. The cap 401 is in direct contact with the ceramic base, which prevents the metal washer 402 from scratching the ceramic surface. The cap 401 can evenly distribute the axial pressure to the ceramic surface to prevent stress concentration from causing cracks.

[0026] The metal washer 402 is placed between the rubber washer 403 and the cap pad 401 as an intermediate layer to evenly transmit the concentrated pressure applied by the rocker arm 501 to the cap pad 401 below.

[0027] The rubber washer 403 is placed on the top layer, and its top surface is in direct contact with the eccentric cam surface 7 of the rocker arm 501. In this embodiment, the contact surface between the rocker arm 501 and the rubber washer 403 (i.e., the eccentric cam surface 7) is set as a rough surface. The rough surface is one or a combination of knurled surface, textured surface, sandblasted surface or fine toothed surface. The rough surface forms a high friction contact with the upper surface of the rubber washer 403, thereby preventing the rocker arm 501 from sliding or displacing relative to the rubber washer 403 under vibration or external force, and ensuring the long-term stability of the locked state.

[0028] In this embodiment, an annular groove 301 is provided on the inner wall of the cap 3 near its lower edge, and the cap pad 401 is provided with an outwardly extending outer edge 6. The upper surface of the outer edge 6 is set as a slope. The cap pad 401 is engaged with the cap 3 by the cooperation of the outer edge and the groove 301. The cap 3 and the cap pad 401 are engaged as one unit by the groove 301 and the slope, ensuring that the cap 3 will not separate from the cap pad 401 during use.

[0029] Based on the above structure, the fixing bolt operates on the following principle: Place the positioning nut 1 into the mounting groove of the toilet flange, ensuring that the positioning nut 1 is stuck in the bottom of the groove and cannot rotate circumferentially, thereby achieving anti-rotation positioning of the positioning nut 1. Pass the lower end of the rod 202 through the rubber washer 403, the metal washer 402 and the cap pad 401 from top to bottom. At this time, the rocker arm 501 is in the unlocked state. Align the toilet base with the flange, and pass the lower end of the rod 202 through the mounting hole of the toilet base. Manually rotate the rocker arm 501, which drives the rod 202 to rotate, causing the lower end of the rod 202 to feed downward along the thread axis of the positioning nut 1, so that the lower surface of the cap 401 contacts the surface of the toilet base. Continue to rotate the screw, and the cap 401 is pressed against the toilet base. The metal washer 402 and the rubber washer 403 move down accordingly, with the stainless steel washer pressing down on the cap 401 to eliminate the installation gap between the toilet base and the flange. During this process, if there is a lateral positional deviation between the rod 202 and the mounting hole of the toilet base, the installer can manually slide the cap 401 before locking, using the adjustment margin provided by the elongated hole to align the cap 401 with the mounting hole and make it evenly adhere to the ceramic surface. The installer presses the rocker arm 501 down around the pin 502, rotating it from the unlocked position by about 90° (i.e., 1 / 4 circumference) to the locked position; Then press the cap 3 in from above to make the cap pad 401 engage with the cap 3, thus completing the installation; When the toilet needs to be disassembled, the operator removes the cap 3, reverses the rocker arm 501 to return it to the unlocked state, and reverses the rod 202 to unscrew the rod 202 from the positioning nut 1, so that the toilet can be disassembled directly.

[0030] When used for toilet installation, this invention eliminates the need for any tools such as wrenches or sockets during the entire installation and removal process. It can be completed by a single person with one hand, eliminating disassembly failures caused by rust or slippage. This significantly shortens installation time and makes maintenance and replacement extremely convenient. Later relocation or repairs do not require concern about rust or tool slippage; simply move the rocker arm and unscrew the screw in the opposite direction for quick disassembly, greatly reducing maintenance difficulty and cost. Furthermore, this fixing bolt is perfectly suited for confined spaces. In the unlocked state, the screw assembly can be freely rotated by hand without requiring any space for tools, solving the problem of tools being unable to enter due to narrow gaps between the toilet base and the wall or floor. The pressure-bearing sealing component and quick-release locking component provide reliable sealing, preventing toilet shaking, leakage, and odor.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
