Description

Technical Field

[0001] This utility model relates to the field of intelligent toilet technology, and more specifically, to a toilet seat cover connection mechanism. Background Technology

[0002] With the continuous improvement of living standards, toilets have become extremely common in modern homes and public places. During daily use, dirt easily accumulates on the toilet surface, especially at the junction of the toilet seat and the lid. Due to the complex structure and narrow gaps, this area easily becomes a breeding ground for dirt and is very difficult to clean. Currently, most toilet seats are fixed using traditional methods such as screws, requiring tools for disassembly during cleaning, a cumbersome process that not only affects daily cleaning efficiency but also reduces user experience. Although there is a clear market demand for toilets with easy-to-clean and quick-assembly / removal structures, existing technology still lacks a connection structure that allows for quick assembly and disassembly between the toilet seat and lid, resulting in inconvenient maintenance and cleaning. Utility Model Content

[0003] The purpose of this utility model is to overcome the problem that the existing technology lacks a connection structure that enables quick assembly and disassembly between the toilet seat and the cover, resulting in inconvenience in cleaning hard-to-clean corners, and to provide a toilet seat cover connection mechanism.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A toilet seat cover connection mechanism is provided, including a base plate hinge shell and a cover ring hinge shell. The back of the base plate hinge shell is fixedly connected to an external toilet seat base, and the front of the cover ring hinge shell is rotatably connected to an external toilet seat cover. The mechanism also includes a driving member and a limiting member installed on the back of the base plate hinge shell. Side slides are provided on both sides of the front of the base plate hinge shell, and a sliding protrusion is provided on the back of the cover ring hinge shell. The sliding protrusion is slidably connected to the side slides. The driving member is connected to the limiting member, and the driving member drives the limiting member to slide to abut against or disengage from the side slides and the sliding protrusion.

[0005] In the operation of the above scheme, when installation is required, the limiting member is first retracted by the driving component (such as a button or knob), disengaging it from the locking area of ​​the side slide. Then, the sliding protrusion on the back of the cover hinge shell is aligned with the side slide entrance on the front of the base plate hinge shell, and pushed horizontally along the slide direction, allowing the sliding protrusion to slide smoothly within the side slide until it reaches the preset fully engaged position. At this point, the driving component is activated, pushing the limiting member to slide. The limiting member then precisely inserts into the side slide and tightly abuts against the side of the sliding protrusion, thus effectively constraining the sliding protrusion radially and firmly locking it within the side slide, completing the rigid connection between the cover hinge shell and the base plate hinge shell. When disassembly and cleaning are required, the operation is reversed: the driving component is activated to drive the limiting member out of the side slide, releasing the radial constraint on the sliding protrusion, allowing the cover hinge shell and toilet seat to be pulled out along the slide in the opposite direction. The entire process requires no tools, enabling one-click quick assembly and disassembly of the toilet seat and base, effectively solving the problem of inconvenient cleaning of hard-to-reach areas.

[0006] Furthermore, the back of the hinged shell of the base plate is provided with an inner sliding groove, a mounting groove, and a through hole. The through hole connects the inner sliding groove and the side sliding track. The limiting member is slidably connected to the inner sliding groove, and the driving member is installed in the mounting groove. The driving member includes a button, a first elastic rod, a connecting rod, and a second elastic rod. The two sides of the button are connected to the first elastic rod, and the two ends of the connecting rod are respectively connected to the first elastic rod and the second elastic rod. The second elastic rod is connected to the limiting member, and the connecting rod is also rotatably connected to the mounting groove. In the initial state, the sliding protrusion extends out of the through hole and the side sliding track. The drive mechanism, equipped with a button, is manually operated. Both the first and second elastic rods are initially bent elastic members. The first elastic rod is fixedly connected at both ends to the button and a connecting rod, respectively, while the connecting rod can rotate relative to the mounting slot. When the button is manually pressed, the first elastic rod, due to its elasticity, pushes the connecting rod to rotate in one direction. The other end of the connecting rod is connected to the second elastic rod, which in turn is connected to a limiting member. The limiting member is confined to the inner slide groove, causing the connecting rod to rotate the second elastic rod. This rotation then causes the limiting member to slide through the through-hole and retract back into the inner slide groove. The above process can also be reversed. When the cover ring hinge shell is installed, the sliding protrusion pushes the limiting member back into the inner slide groove. Once the sliding protrusion slides within the side slide track until it reaches the preset fully engaged position, the limiting member automatically pops out of the through-hole under the elastic action of the first and second elastic rods, locking the sliding protrusion within the side slide track.

[0007] Furthermore, the driving component also includes a hook, which is fixedly connected to the button. The front of the hinged shell of the base plate is provided with a limiting groove, which communicates with the mounting groove. The bottom surface of the limiting groove is provided with a claw protrusion. The hook can slide into the limiting groove and connect with the claw protrusion. Since the first elastic rod and the second elastic rod are curved elastic rods, after the button is pressed down, the hook slides down synchronously in the limiting groove until the hook hooks the claw protrusion on the bottom surface of the limiting groove. At this time, the operator can release the hand that pressed the button, while the button remains in the pressed state. The operator does not need to press continuously, freeing up one of the operator's hands and making installation more convenient.

[0008] Furthermore, the end of the hook away from the button is provided with a mating protrusion, which is located on the surface of the hook near the limiting slide groove. The mating protrusion is connected to the claw protrusion. The back of the cover ring hinge shell is provided with a release protrusion, which can slide into the limiting slide groove and abut against the hook. There are two hooks arranged opposite each other. When the cover ring hinge shell slides into the bottom plate hinge shell, the release protrusion pushes open the hook, causing the hook to bend and deform, forming a flared opening. The release protrusion slides synchronously between the two hooks through the flared opening. At this time, the cover ring hinge shell and the bottom plate hinge shell are at the same position. When disassembly is required after installation, pressing down the button causes the hook to slide. Since the mating protrusion is located on the bottom surface of the hook, it can hook onto the claw protrusion for fixation. At this time, the limiting component is retracted into the inner slide groove. The operator can then release one hand that was pressing the button and slide the cover ring hinge shell. The hook protrusion slides simultaneously, pushing open the hooks on both sides again and forming an opening. As the opening is formed, the mating protrusion can disengage from the claw protrusion. At this time, under the elastic action of the first and second elastic rods, the button rebounds, causing the hook to slide upward. Simultaneously, the limiting component automatically pops out of the through hole.

[0009] Furthermore, the connecting rod has a locking protrusion on its flat surface and a locking hole on its mounting groove, and the locking protrusion engages with the locking hole; the mounting groove has a cylindrical protrusion, and the locking hole is located at the center of the cylindrical protrusion, and the connection between the locking hole and the locking protrusion enables the connecting rod to rotate relative to the mounting groove.

[0010] Furthermore, the button, the first elastic rod, the connecting rod, the second elastic rod, and the limiting member are integrally formed; an anti-slip pad is provided on the side of the side slide near the mounting groove; each part of the driving member is integrally formed with the limiting member, so that the elastic response of the first elastic rod and the second elastic rod can be faster and the movement is smoother.

[0011] Furthermore, it also includes an adjustable mounting plate. Adjustable channels are provided on both sides of the mounting groove. The length of the adjustable channels is greater than the length of the adjustable mounting plate. The adjustable mounting plate abuts against the adjustable channels and is detachably connected to the external toilet base. The length of the adjustable channels is greater than the length of the adjustable mounting plate. The adjustable mounting plate can be installed at different positions along the length of the adjustable channels to increase the adjustment range and adapt to most toilet base installation points on the market.

[0012] Furthermore, the inner walls of the adjusting channel are provided with first anti-slip steps on both sides, and the adjusting mounting plate is provided with second anti-slip steps at both ends. Both the first and second anti-slip steps have a plurality of toothed protrusions arranged on them, and the toothed protrusions of the first and second anti-slip steps abut against each other. This abutment between the first and second anti-slip steps allows the adjusting mounting plate to abut against the adjusting channel. The adjusting mounting plate has a threaded hole at its center, and is fixedly connected to the external toilet base via threads. Simultaneously, the toothed protrusions of the first and second anti-slip steps interlock, and the cross-section of the toothed protrusions is triangular, preventing slippage when the adjusting mounting plate is installed and fixed to the external toilet base. This completely fixes the entire base plate hinge shell to the toilet base.

[0013] Furthermore, it also includes a hinge and a baffle. The front of the cover ring hinge shell is provided with a hinge shell, the cavity of the hinge shell is connected to the back of the cover ring hinge shell, the two ends of the hinge shell are provided with hinge holes, and the inner wall of the hinge shell is provided with a slot. The hinge is slidably connected to the hinge hole, and the baffle is detachably connected to the slot and abuts against the hinge. The back of the cover ring hinge shell is provided with an opening that communicates with the hinge shell. When installing the toilet seat cover and the cover ring hinge shell, first insert the hinge into the hinge hole, then align the hinge hole with the installation hole of the toilet seat cover, and then manually push the hinge outward from the opening on the back of the cover ring hinge shell until it is inserted into the installation hole of the toilet seat cover and the seat ring. Finally, insert the fixed baffle into the slot. The baffle blocks the hinge and prevents it from sliding back into the hinge hole. The whole installation process is simple, the number of connected structural parts is small, and there is no need to use complex structural parts such as springs, resulting in low manufacturing cost.

[0014] Furthermore, the hinge includes a first column and a second column. The outer wall of the second column is provided with a plurality of guide protrusions in a circumferential direction, and the inner wall of the hinge shell is provided with a plurality of guide grooves in a circumferential direction. The guide protrusions are inserted into the guide grooves. On the one hand, the guide protrusions prevent the hinge from rotating in the hinge hole, thus avoiding friction causing the hinge to rotate and wear in the hinge hole when the toilet seat cover rotates. On the other hand, they can guide the sliding of the hinge during installation.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. Side sliding tracks are provided on both sides of the front of the base plate hinge shell, and sliding protrusions are provided on the back of the cover ring hinge shell. The sliding protrusions are slidably connected to the side sliding tracks. The driving component is connected to the limiting component. During installation, the driving component pushes the limiting component to slide into the side sliding track and tightly abut against the side of the sliding protrusion. During disassembly and cleaning, the driving component drives the limiting component to exit from the side sliding track, releasing the radial restriction on the sliding protrusion. Without any tools, one-click quick disassembly and assembly between the toilet seat and the base can be achieved, effectively solving the problem of inconvenient cleaning of hard-to-clean corners.

[0016] 2. The inner walls of the regulating channel are provided with first anti-slip steps on both sides, and the regulating mounting plate is provided with second anti-slip steps at both ends. The toothed protrusions of the first and second anti-slip steps interlock and abut against each other, effectively preventing the regulating mounting plate from slipping when it is installed and fixed on the external toilet base.

[0021] Example 1 This embodiment is a first embodiment of a toilet seat cover connection mechanism, such as... Figures 2 to 8As shown, the device includes a base plate hinge shell 100 and a cover ring hinge shell 200. The back of the base plate hinge shell 100 is fixedly connected to the external toilet seat base, and the front of the cover ring hinge shell 200 is rotatably connected to the external toilet seat cover. It also includes a drive member 300 and a limiting member 400 installed on the back of the base plate hinge shell 100. Side slides 110 are provided on both sides of the front of the base plate hinge shell 100, and a sliding protrusion 210 is provided on the back of the cover ring hinge shell 200. The sliding protrusion 210 is slidably connected to the side slides 110. The drive member 300 is connected to the limiting member 400, and the drive member 300 drives the limiting member 400 to slide to abut against or disengage from the side slides 110 and the sliding protrusion 210.

[0022] Specifically, the back of the base plate hinge shell 100 is provided with an inner sliding groove 120, a mounting groove 130, and a through hole 140. The through hole 140 connects the inner sliding groove 120 and the side sliding track 110. The limiting member 400 is slidably connected to the inner sliding groove 120, and the driving member 300 is installed in the mounting groove 130. The driving member 300 includes a button 310, a first elastic rod 320, a connecting rod 330, and a second elastic rod 340. The two sides of the button 310 are connected to the first elastic rod 320, and the two ends of the connecting rod 330 are respectively connected to the first elastic rod 320 and the second elastic rod 340. The second elastic rod 340 is connected to the limiting member 400, and the connecting rod 330 is also rotatably connected to the mounting groove 130. Figure 3 and Figure 4 As shown, in the initial state, the sliding protrusion 210 extends out of the through hole 140 and abuts against the side slide rail 110. The driving component 300 is equipped with a button 310 and is manually driven. The first elastic rod 320 and the second elastic rod 340 are both bent elastic rods in the initial state. The two ends of the first elastic rod 320 are fixedly connected to the button 310 and the connecting rod 330, respectively. The connecting rod 330 can rotate relative to the mounting groove 130. When the button 310 is manually pressed down, the first elastic rod 320 will push the connecting rod 330 to rotate in one direction due to its elasticity. The other end of the connecting rod 330 is connected to the second elastic rod 340, which is connected to the limiting member 400. The limiting member 400 is restricted on the inner slide groove 120. Thus, the connecting rod 330 will drive the second elastic rod 340 to rotate. The rotation of the second elastic rod 340 will then drive the limiting member 400 to slide through the through hole 140 and retract into the inner slide groove 120. The above-mentioned action process can also be performed in reverse. That is, when the cover ring hinge shell 200 is installed, the sliding protrusion 210 pushes the limiting member 400 back into the inner slide groove 120. When the sliding protrusion 210 slides in the side slide 110 until it reaches the preset fully engaged position, the limiting member 400 automatically pops out of the through hole 140 under the elastic action of the first elastic rod 320 and the second elastic rod 340, and locks the sliding protrusion 210 in the side slide 110.

[0023] like Figure 7As shown, the end face of the limiting member 400 extending out of the through hole 140 is set as a bevel so that the sliding protrusion 210 can press the limiting member 400 into the inner groove 120 during installation.

[0024] Specifically, the drive component 300 also includes a latch 350, which is fixedly connected to the button 310, such as... Figure 5 As shown, the front of the base plate hinge shell 100 is provided with a limiting slide groove 150, which is connected to the mounting groove 130. The bottom surface of the limiting slide groove 150 is provided with a hook protrusion 151. The hook 350 can slide into the limiting slide groove 150 and connect with the hook protrusion 151. Since the first elastic rod 320 and the second elastic rod 340 are curved elastic rods, after the button 310 is pressed down, the hook 350 slides down in the limiting slide groove 150 until the hook 350 hooks the hook protrusion 151 on the bottom surface of the limiting slide groove 150. At this time, the operator can release the hand that pressed down the button 310, while the button 310 remains in the pressed state. The operator does not need to press continuously, freeing up one of the operator's hands and making the installation more convenient.

[0025] Specifically, the end of the hook 350 furthest from the button 310 has a mating protrusion 351. The mating protrusion 351 is located on the surface of the hook 350 near the limiting slide groove 150, and it connects with the claw protrusion 151. Figure 8 As shown, the back of the cover ring hinge shell 200 is provided with a release protrusion 220, which can slide into the limiting groove 150 and abut against the hook 350, as shown. Figure 6 As shown, the end faces of the hook 350 and the claw protrusion 151 that are in contact with each other are provided with bevels, so that when the button 310 is pressed, the bevel of the hook 350 slides along the bevel of the claw protrusion 151, and the hook 350 can be opened to form an flared opening, so that the two can be smoothly engaged and connected.

[0026] Two hooks 350 are provided and positioned opposite each other. During installation, the cover ring hinge shell 200 slides into the base plate hinge shell 100, and at the same time, the disengagement protrusion slides above the hook claw protrusion 151 and pushes open the hook 350, causing the hook 350 to bend and deform, forming a flared opening. The disengagement protrusion 220 slides synchronously between the two hooks 350 through the flared opening. After completion, as shown... Figure 6As shown, at this time, the cover ring hinge shell 200 and the base plate hinge shell 100 are in the installed state, but the mating protrusion 351 has not yet engaged with the hook protrusion 151. When disassembly is required, pressing down button 310 causes hook 350 to slide. Since the mating protrusion 351 is located on the bottom surface of hook 350, it can hook the claw protrusion 151 for fixation. At this time, the limiting member 400 is retracted into the inner slide groove 120. The operator can then release one hand that is pressing button 310 and slide the cover ring hinge shell 200. The disengagement protrusion 220 slides simultaneously, pushing open the hooks 350 on both sides again and forming an opening. As the opening is formed, the mating protrusion 351 can disengage from the claw protrusion 151. At this time, under the elastic action of the first elastic rod 320 and the second elastic rod 340, button 310 rebounds and drives hook 350 to slide upward. At the same time, the limiting member 400 automatically pops out through hole 140.

[0027] Specifically, the connecting rod 330 has a locking protrusion 331 on its flat surface, and the mounting groove 130 has a locking hole 131. The locking protrusion 331 engages with the locking hole 131. The mounting groove 130 has a cylindrical protrusion, and the locking hole 131 is located at the center of the cylindrical protrusion. The connection between the locking hole 131 and the locking protrusion 331 enables the connecting rod 330 to rotate relative to the mounting groove 130.

[0028] Specifically, the button 310, the first elastic rod 320, the connecting rod 330, the second elastic rod 340, and the limiting member 400 are integrally formed; an anti-slip pad 500 is provided on the side of the side slide 110 near the mounting groove 130; each part of the drive member 300 is integrally formed with the limiting member 400, so that the elastic response of the first elastic rod 320 and the second elastic rod 340 can be faster and the movement is smoother.

[0029] The working principle of a toilet seat cover connection mechanism in this embodiment is as follows: When the operator aligns the sliding protrusion 210 on the back of the cover ring hinge shell 200 with the entrance of the side slide rail 110 on the front of the base plate hinge shell 100 and pushes it horizontally, the inclined surface of the front end of the sliding protrusion 210 will first contact and press against the inclined surface of the limiting member 400, which has initially popped out in the side slide rail 110. This pushing force will be converted into a radial component force, forcing the limiting member 400 to overcome the elastic force of its rear end second elastic rod 340 and retract into the inner slide groove 120 on the back of the base plate hinge shell 100.

[0030] As the sliding protrusion 210 continues to extend deeper into the side slide rail 110, the release protrusion 220 fixed to the back of the cover ring hinge shell 200 also slides into the limiting slide groove 150 on the front of the bottom plate hinge shell 100. After the release protrusion 220 slides above the hook protrusion 151, it will open a pair of oppositely arranged hooks 350 in the groove, causing them to bend and deform temporarily and form an flared opening, and slide between the two hooks 350. When the sliding protrusion 210 finally slides to the fully engaged position at the end of the side slide rail 110, the sliding protrusion 210 disengages from the through hole 140 and no longer applies pressure to the limiting member 400. The elastic potential energy of the second elastic rod 340, which was previously in a compressed and stored state, is released instantaneously, driving the limiting member 400 to quickly pop out of the through hole 140 and fit against the sliding protrusion 210, thereby fixing it. At the same time, the release protrusion 220 reaches the middle position of the two hooks 350.

[0031] During disassembly, button 310 needs to be pressed down once. Button 310 drives connecting rod 330 to rotate clockwise by a certain angle via first elastic rod 320, which in turn drives second elastic rod 340 to pull limiting member 400 back into inner slide groove 120. At the same time, hook 350 moves down and is temporarily locked by claw protrusion 151, keeping first elastic rod 320 and second elastic rod 340 in an elastic energy storage state and limiting member 400 pulled into through hole 140. At this time, the cover ring hinge shell 200 can be pulled out in the reverse direction. Its disengagement protrusion 220 will again open hook 350 and disengage them from claw protrusion 151. First elastic rod 320 and second elastic rod 340 reset under the action of elastic force. When sliding protrusion 210 is completely pulled out of side slide 110, limiting member 400 pops out of through hole 140, preparing for the next installation cycle.

[0032] The beneficial effects of this embodiment are: the entire process of disassembly and installation requires no tools, realizing one-click quick disassembly and assembly between the toilet seat and the base, effectively solving the problem of inconvenient cleaning of hard-to-clean corners.

[0033] Example 2 This embodiment is a second embodiment of a toilet seat cover connection mechanism, such as... Figures 3 to 5 As shown, the difference from Embodiment 1 is as follows: Specifically, it also includes an adjustable mounting plate 600. Adjustable channels 160 are provided on both sides of the mounting groove 130. The length of the adjustable channels 160 is greater than the length of the adjustable mounting plate 600. The adjustable mounting plate 600 abuts against the adjustable channels 160 and is detachably connected to the external toilet base. The length of the adjustable channels 160 is greater than the length of the adjustable mounting plate 600. The adjustable mounting plate 600 can be installed at different positions along the length of the adjustable channels 160, increasing the adjustment range to accommodate most toilet base installation points on the market.

[0034] Specifically, the inner walls of the adjusting channel 160 are provided with first anti-slip steps 161 on both sides, and the adjusting mounting plate 600 is provided with second anti-slip steps 610 at both ends. Both the first and second anti-slip steps 161 and 610 have several toothed protrusions arranged on them, which abut against each other. This abutment between the first and second anti-slip steps 161 and 610 enables the adjusting mounting plate 600 to abut against the adjusting channel 160. The adjusting mounting plate 600 has a threaded hole at its center, which is then fixedly connected to the external toilet base via threads. Simultaneously, the toothed protrusions of the first and second anti-slip steps 161 and 610 interlock and interlock, with the cross-section of the toothed protrusions being triangular, preventing slippage when the adjusting mounting plate 600 is installed and fixed to the external toilet base. This completely fixes the entire base plate hinge shell 100 to the toilet base.

[0035] The working principle of a toilet seat cover connection mechanism in this embodiment is as follows: During installation, the adjusting mounting plate 600 with the second anti-slip step 610 is first placed in the adjusting groove 160 of the base plate hinge shell 100. Since the length of the adjusting groove 160 is greater than that of the adjusting mounting plate 600, the adjusting mounting plate 600 can slide freely within a certain range in the groove, thus flexibly adjusting its position relative to the toilet base mounting hole. After alignment, the adjusting mounting plate 600 is secured to the toilet base by bolts passing through the threaded hole in the center. During tightening, the adjusting mounting plate 600 is subjected to a clamping force, causing the second anti-slip steps 610 at both ends to tightly press against the first anti-slip step 161 on the inner wall of the adjusting groove 160. At this time, the densely distributed triangular-shaped toothed protrusions on the two steps mesh with each other, forming a strong mechanical interlock, effectively preventing the adjusting mounting plate 600 from sliding in any direction, thereby firmly locking the base plate hinge shell 100 in the adjusted optimal position and ensuring the stability of the overall connection structure.

[0036] The beneficial effects of this embodiment are: the adjustable mounting plate 600 can be installed at different positions along the length of the adjustable channel 160, increasing the adjustment range to accommodate most toilet base installation points on the market, effectively improving the applicability of the connection mechanism.

[0037] Example 3 This embodiment is a third embodiment of a toilet seat cover connecting mechanism, such as... Figure 1 and Figure 2 As shown, the difference from Embodiment 1 is as follows: Specifically, such as Figure 2As shown, it also includes a hinge 700 and a baffle 800. A hinge shell 230 is provided on the front of the cover ring hinge shell 200. The cavity of the hinge shell 230 communicates with the back of the cover ring hinge shell 200. Hinge holes 231 are provided at both ends of the hinge shell 230. A slot 232 is provided on the inner wall of the hinge shell 230. The hinge 700 is slidably connected to the hinge holes 231. The baffle 800 is detachably connected to the slot 232 and abuts against the hinge 700. An opening is provided on the back of the cover ring hinge shell 200, communicating with the hinge shell 230. Figure 1 As shown, when installing the toilet seat cover 910 and the seat ring hinge shell 200, first insert the hinge 700 into the hinge hole 231, then align the mounting holes of the toilet seat cover 910 with the hinge hole 231, and then manually push the hinge 700 outward from the opening on the back of the seat ring hinge shell 200 until it is inserted into the mounting holes of the toilet seat cover 910 and the seat ring 900. Finally, insert the fixing baffle 800 into the slot 232. The baffle 800 blocks the hinge 700 so that it cannot slide back into the hinge hole 231. The whole installation process is simple, the number of connected structural parts is small, and there is no need to use complex structural parts such as springs, resulting in low manufacturing costs.

[0038] Specifically, the hinge 700 includes a first column 710 and a second column 720. The outer wall of the second column 720 is provided with a plurality of guide protrusions 721 circumferentially, and the inner wall of the hinge shell 230 is provided with a plurality of guide grooves 233 circumferentially. The guide protrusions 721 are inserted into the guide grooves 233. On the one hand, the guide protrusions 721 prevent the hinge 700 from rotating in the hinge hole 231, thus avoiding friction from causing the hinge 700 to rotate and wear in the hinge hole 231 when the toilet seat cover 910 rotates. On the other hand, they can guide the sliding of the hinge 700 during installation.

[0039] The working principle of a toilet seat cover connection mechanism in this embodiment is as follows: During installation, first insert the hinge 700 into the hinge hole 231 of the hinge shell 230 on the front of the cover ring hinge shell 200 from one end of its first column 710. Then, align the mounting holes of the seat ring 900 and the cover 910 with one end of the second column 720 of the hinge 700. At this point, the operator can reach through the opening on the back of the cover ring hinge shell 200 and manually push the hinge 700 outwards, causing its first column 710 to pass through the hinge hole 231 of the hinge shell 230, while the second column 720 inserts into and passes through the mounting holes of the seat ring 900 and the cover 910, thus forming a hinged connection. During this process, the guide protrusion 721 on the second column 720 of the hinge 700 slides along the guide groove 233 on the inner wall of the hinge shell 230, ensuring smooth alignment during insertion and effectively preventing rotational wear of the hinge 700 during future use. Finally, a baffle 800 is inserted from the side into the slot 232 on the inner wall of the hinge housing 230. The baffle 800 immediately abuts against the end of the hinge 700, forming a mechanical block to prevent the hinge 700 from slipping off accidentally.

[0040] The advantages of this embodiment are: by eliminating complex components such as springs, a firm hinged fixation can be achieved with only a few simple steps and a small number of parts, making assembly and disassembly convenient and cost-effective.
