Description

Technical Field

[0001] This utility model relates to the field of toilet technology, and more specifically to a lid mounting structure and a liftable toilet. Background Technology

[0002] Currently, smart toilet seats are mostly fixed to ceramic toilets using screws. Specifically, during installation, a long screw is passed through the screw holes of the smart toilet seat and screwed into the connection structure of the ceramic toilet. By continuously tightening the long screw, the smart toilet seat gradually fits against the upper surface of the ceramic toilet, thus completing the fixed installation.

[0003] However, the above installation methods often require screws with a long stroke to achieve the locking effect, which is cumbersome and time-consuming. When performing maintenance work such as replacing or repairing the smart cover, the long screws must be loosened first, which also results in time-consuming disassembly, making the entire disassembly and assembly process inefficient. Utility Model Content

[0014] In addition, this utility model also proposes a lifting toilet, including the above-mentioned cover installation structure. The cover includes a cover body and a support plate, and also includes a lifting component. The lifting component is disposed between the cover body and the support plate for lifting the cover body. A locking device is disposed between the support plate and the base to drive the lifting component. After the cover body is lifted, an operating space is formed between the cover body and the toilet. The operating space is used to facilitate the driving of the drive component.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] 1. By setting a base on the toilet, and setting a first locking component and a second locking component on the seat and the base respectively, it is not necessary to rotate the long stroke screw to fix the seat to the toilet. The seat can be quickly installed and removed by simply driving the first locking component to switch between the "locked position (first position)" and the "unlocked position (second position)".

[0017] 2. The first locking component is a limiting slider with a through hole, and the second locking component is a locking shaft with a limiting boss. When the first locking component is in the first position, the locking shaft is misaligned with the through hole, and the limiting boss is engaged with the edge of the through hole, thereby restricting the cover plate to the base. When the first locking component is in the second position, the locking shaft is aligned with the through hole, the limiting boss is separated from the edge of the through hole, and the limiting boss can pass through the through hole, allowing the cover plate to be separated from the base.

[0018] 3. When the cover plate is installed on the base, the limiting block is pushed upward to achieve the threaded connection of the drive bolt. By screwing the drive bolt forward, the switching slider is pushed to move the first locking member from the first position to the second position, thereby unlocking. When the cover plate is separated from the base, the limiting block slides downward to separate from the drive bolt. When the drive bolt is not in the threaded state, the reset spring can directly push the switching slider outward, and the switching slider pushes the drive bolt to achieve reset.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0031] Example 1

[0032] A cover plate mounting structure, such as Figures 1 to 5 As shown, the toilet includes a cover plate 1 and a base 2 mounted on the toilet 13. A locking device 3 is provided between the cover plate 1 and the base 2, and the cover plate 1 is fixed to the base 2 by the locking device 3. The base 2 and the toilet 13 can be integrally formed or separately. In this embodiment, the base 2 and the toilet 13 are separately formed. The bottom of the base 2 has a threaded post. After the threaded post passes through the toilet seat, a nut 12 is screwed in from below to fix the base 2.

[0033] The cover plate 1 has horizontally arranged L-shaped or T-shaped fixing boxes 11. The locking device 3 includes a first locking member disposed on the fixing box 11 and a second locking member disposed on the base 2. The first locking member is movably disposed on the fixing box 11 and can move between a first position and a second position. When the first locking member is in the first position, the first locking member and the second locking member are locked together, so that the cover plate 1 is fixed on the base 2; when the first locking member is in the second position, the first locking member and the second locking member are unlocked, so that the cover plate 1 can be removed from the base 2. It also includes a driving member 4, which is used to drive the first locking member to switch between the first position and the second position. In other embodiments, the first locking member may also be disposed on the base 2, and the second locking member may be disposed on the fixing box 11 accordingly.

[0034] The first locking component is a limiting slider 301 that is slidably mounted on the fixed box 11. The limiting slider 301 has a through hole 303 that is vertically opened. The second locking component is a locking shaft 302 mounted on the base 2. The locking shaft 302 is vertically fixed on the base 2. When the cover plate 1 is installed on the base 2, the locking shaft 302 passes through the through hole 303. A limiting boss 304 is provided on the locking shaft 302. A groove is provided on the peripheral sidewall of the locking shaft 302 corresponding to the snap-fit ​​position of the through hole 303 to form the limiting boss 304. When the first locking component moves from the second position to the first position, the through hole 303 and the locking shaft 302 are misaligned, so that the limiting boss 304 snaps with the edge of the through hole 303, thus fixing the first locking component on the base 2. When the first locking component moves from the first position to the second position, the through hole 303 and the locking shaft 302 are aligned, the limiting boss 304 separates from the edge of the through hole 303, and the limiting boss 304 can pass through the through hole 303, so that the first locking component can be separated from the base 2. In this embodiment, two locking shafts 302 are provided on the base 2, and the two locking shafts 302 are arranged along the moving direction of the limiting slider 301. Two corresponding through holes 303 are also provided on the limiting slider 301. The through holes 303 can be through holes that pass through the limiting slider 301 or slots that do not pass through the limiting slider 301.

[0035] The driving component includes a slidably mounted switching slider 401. A first engaging structure is provided between the switching slider 401 and the limiting slider 301. The switching slider 401 has a locked position and an unlocked position. When the switching slider 401 moves to the unlocked position, it abuts against and pushes the limiting slider 301 from the first position to the second position through the first engaging structure. When the switching slider 401 moves to the locked position, the switching slider 401 no longer abuts against the limiting slider 301, and the limiting slider 301 moves from the second position to the first position. In this embodiment, the switching slider 401 is slidably mounted on the fixed box 11. Both the limiting slider 301 and the switching slider 401 move horizontally, and their directions of movement are perpendicular. It also includes a first reset component located at the end of the limiting slider 301 away from the switching slider 401. The first reset component is a reset spring 402, which is positioned along the direction of movement of the limiting slider 301. One end of the reset spring 402 contacts the limiting slider 301, and the other end contacts the inner wall of the fixed box 11. A first engagement structure, namely an inclined surface 5, is provided between the switching slider 401 and the limiting slider 301. When the switching slider 401 slides to the unlocked position, it abuts against the limiting slider 301 through the inclined surface 5 and pushes it to move towards the return spring 402, that is, from the first position to the second position, and compresses the return spring 402. When the switching slider 401 slides back to the locked position, the switching slider 401 no longer abuts against the limiting slider 301. When the return spring 402 rebounds at this time, it pushes the limiting slider 301 from the second position to the first position, thereby achieving reset.

[0036] In this embodiment, "no longer pushing" can mean that the switching slider 401 and the limiting slider 301 are no longer in contact or are only in contact. When they are no longer in contact or are only in contact, the switching slider 401 no longer exerts a force on the limiting slider 301 to push it from the first position to the second position. In other embodiments, the switching slider 401 can also pull the limiting slider 301 from the first position to the second position through a first engaging structure. The first engaging structure can be a pull rope or other flexible connector. During the sliding process of the switching slider 401, the limiting slider 301 can be synchronously driven to undergo a certain displacement through the pull rope, thereby realizing the movement of the limiting slider 301 from the first position to the second position. The movement of the limiting slider 301 from the second position to the first position can also be achieved using a pull rope structure.

[0037] The driving component includes a driving bolt 403. One end of the switching slider 401 is rotatably connected to the driving bolt 403. One end of the driving bolt 403 is installed inside the switching slider 401 and is restricted from disengaging from the switching slider 401 by a retaining ring 14, but can rotate. The driving bolt 403 has a threaded portion, which is threadedly connected to the cover plate 1. In this embodiment, specifically, the threaded portion of the driving bolt 403 is threadedly connected to the fixing box 11. By rotating the driving bolt 403, the user causes the driving bolt to shift, pushing the switching slider 401 to slide. The driving bolt 403 screws into the fixing box 11, abutting against the switching slider and pushing the switching slider 401 to slide inward, so that the switching slider 401 pushes the limiting slider 301 from the first position to the second position via the inclined surface 5. In other embodiments, the drive bolt 403 can also pull the switching slider 401 to slide. The pulling can be achieved by using a pull rope or other flexible connectors. During the displacement of the drive bolt 403, the switching slider 401 can be synchronously driven to move to a certain displacement by the pull rope, thereby realizing the movement of the switching slider 401 from the locked position to the unlocked position. The movement of the switching slider 401 from the unlocked position to the locked position can also be achieved by using a pull rope structure. When the drive bolt 403 is connected to the switching slider 401 by using a pull rope structure, the pull rope structure can be rotatably connected to the drive bolt 403 or the switching slider 401. For example, a rotatable snap ring is provided at the end of the drive bolt 403, and the snap ring 14 is fixed to the pull rope.

[0038] The threaded portion of the drive bolt 403 is threadedly connected to the fixed box 11 via a limiting block 6. The fixed box 11 has an opening 10, and the drive bolt 403 is movably connected within the opening 10 to drive the limiting slider 301 to move. The wall of the opening 10 is a smooth surface. In this embodiment, the movable connection is specifically achieved through a threaded connection to move the position. The cover plate 1 is movably provided with a limiting block 6, specifically, the limiting block 6 is slidably provided on the fixed box 11. The end of the limiting block 6 is provided with an external thread 7, which can selectively extend into the opening 10 to engage with the drive bolt 403. The limiting block 6 can be in a third position and engage with the first... Switching between four positions: When the limiting block 6 is in the third position, the driving bolt 403 engages with the external thread 7 to achieve a threaded connection. When the limiting block 6 is in the fourth position, the limiting block 6 separates from the driving bolt 403. The end of the switching slider 401 furthest from the driving bolt 403 is equipped with a second reset element, which is a reset spring 8. When the driving bolt 403 screws inward, causing the switching slider 401 to slide inward, it compresses the reset spring 8. When the limiting block 6 is in the fourth position, since the limiting block 6 separates from the driving bolt 403, the driving bolt 403 is de-threaded, and the reset spring 8 rebounds, directly pushing the switching slider 401 and simultaneously resetting the driving bolt 403. "Smooth wall surface" should refer to any wall surface that does not affect the reset of the driving bolt 403. For example, a rough wall surface with certain particles may be used to slow down the reset time of the driving bolt in actual use, but ultimately does not affect the reset of the driving bolt 403. In this case, it should still be interpreted as a smooth wall surface in this solution. In other embodiments, the drive bolt 403 may also be configured to have a hole in the base 2 and be threaded to the base 2.

[0039] The limit slider 301 and the switching slider 401 each have a protruding mounting post, and the reset spring 402 and the reset compression spring 8 are respectively sleeved on the mounting post; the cover plate 1 fixing box 11 is respectively provided with mounting tubes for mounting the reset spring 402 and the reset compression spring 8, and the end of the reset spring 402 and the reset compression spring 8 that contacts the box body is set in the mounting tube to improve the stability of the spring.

[0040] like Figure 6As shown, the fixing box 11 of the cover plate 1 has a horizontal opening 10 with a smooth wall. The fixing box 11 has a sliding hole 9 that runs vertically through the hole. The side wall of the opening 10 communicates with the sliding hole 9. The sliding hole 9 is vertically opened and its top end communicates with the opening 10. An external thread is provided at the top of the limiting block 6. The external thread 7 at the top of the limiting block 6 passes through the top of the sliding hole 9 into the opening 10 and engages with the drive bolt 403. The base 2 has a pushing surface for the limiting block 6. The limiting block 6 is slidably connected to the sliding hole 9, and its bottom end can protrude from the sliding hole 9. The limiting block 6 is slidably connected to the sliding hole 9. An anti-detachment structure is provided between the limiting block 6 and the sliding hole to prevent the limiting block 6 from detaching from the sliding hole 9. This structure can be a combination of a sliding groove and a locking block, which does not affect the sliding of the limiting block 6 while preventing the limiting block 6 from detaching. When the cover plate 1 is installed on the base 2, the bottom end of the limiting block 6 is pushed upward by the surface of the base 2, i.e., the pushing surface, so that the limiting block 6 moves from the fourth position to the third position. The external thread 7 at the top of the limiting block 6 engages with the driving bolt 403 to achieve a threaded connection of the driving thread. When the cover plate 1 is separated from the base 2, the limiting block 6 slides downward under the action of gravity, the external thread 7 of the limiting block 6 separates from the driving bolt 403, the thread of the driving bolt 403 is released from the limiting position, and the second reset member pushes the driving bolt 403 to reset. In other embodiments, a spring or magnet can also be used to achieve the downward sliding of the limiting block 6. In other embodiments, the wall of the opening 10 can have a thread that engages with the thread of the driving bolt 403. In this case, only a screwdriver is needed to rotate the driving bolt 403, thereby driving the driving bolt 403 to move in a direction toward the inside or outside of the fixed box 11, which can drive the switching slider to slide accordingly. Compared with the solution in this embodiment, the solution in this embodiment is faster and more convenient when the driving bolt 403 is reset.

[0041] The bottom of the fixing box 11 is also provided with a clearance hole 16 corresponding to the through hole 303. The fixing box 11 is provided with a through hole corresponding to the location of the driving component. The driving component can be driven by extending into the through hole or the driving component can be extended out of the through hole for easy driving. An operating space corresponding to the through hole is provided between the cover plate 1 and the toilet 2. In this embodiment, the fixing box 11 is provided with a through hole corresponding to the location of the driving component. The through hole is the opening 10. In use, the driving bolt 403 is rotated with a screwdriver to move it into the fixing box 11. At this time, the screwdriver will extend into the through hole. In other embodiments, when the wall of the opening 10 is threaded and mates with the thread of the driving bolt 403, the screwdriver can be extended into the through hole to rotate the driving bolt 403. The operating space refers to the clearance space that the user needs to extend from outside the toilet and the cover plate into the space between the cover plate and the toilet to operate the locking device. This space can be the space exposed after the cover plate is raised, or it can be the clearance space originally set on the toilet or the cover plate.

[0042] like Figure 7As shown, this embodiment also proposes a lifting toilet 13, including the aforementioned seat plate 1 installation structure. The seat plate 1 includes a seat plate body and a support plate 17, and also includes a lifting assembly 15. The lifting assembly 15 is disposed between the seat plate body and the support plate 17 for lifting the seat plate body. A locking device is disposed between the support plate 17 and the base 2 to drive the lifting assembly 15. After the seat plate body is lifted, an operating space is formed between the seat plate body and the toilet, which is used to facilitate the driving of the driving component. Specifically, in this embodiment, the fixing box 11 is fixed to the support plate 17.

[0043] The working process of this utility model is as follows:

[0044] When installing the cover plate 1, the limiting slider 301 is in the first position. Since the top of the locking shaft 302 has a guide chamfer, the locking shaft 302 can push the limiting slider 301 during the insertion process, so that the locking shaft 302 passes directly upward through the through hole 303. The limiting slider 301 returns to the first position under the action of the return spring 402, and the cover plate 1 is locked on the base 2 to complete the installation.

[0045] When it is necessary to remove the cover plate 1, screw the drive bolt 403 inward, and the switching slider 401 moves inward through the inclined plane 5 to push the limit slider 301 to the second position. At this time, the through hole 303 is aligned with the locking shaft 302, and the cover plate 1 can be lifted directly to separate from the base 2.

[0046] Example 2:

[0047] like Figure 8 As shown, compared with Embodiment 1, the switching slider 401 is not driven by the driving bolt 403. The switching slider 401 is formed with a driving part that extends out of the opening 10. The driving part is slidably connected to the opening 10. The user can directly pinch the driving part to drive the switching slider 401 to switch between the unlocked position and the locked position.

[0048] In this embodiment, the specific driving unit is a push rod 404 fixed to the end of the switching slider 401 facing the opening 10. The end of the push rod 404 away from the switching slider 401 extends out of the opening 10 and has a gripping block. When the user pinches the gripping block and pushes it into the opening 10, the gripping block abuts against the opening and cannot be pushed further in when the switching slider 401 moves to the unlocked position. The end of the switching slider 401 away from the push rod 404 is also provided with a return spring 8. When the user releases the gripping block, the return spring 8 rebounds and pushes the switching slider 401 outward from the unlocked position to the locked position; or the return spring 8 may not be provided, and the user can manually pull the push rod 404 outward to move the switching slider 401 from the unlocked position to the unlocked position.

[0049] Example 3:

[0050] like Figure 9As shown, compared to Embodiment 3, the driving component includes a driving bolt 403, which is threadedly connected to the cover plate 1 or the base 2. In this embodiment, the driving bolt 403 is threadedly connected to the cover plate 1. A second mating structure is provided between the driving bolt 403 and the limiting slider 301. By rotating the driving bolt 403, the driving bolt 403 is displaced, and the second mating structure causes the driving bolt 403 to push or pull the limiting slider 301 from the first position to the second position. In this embodiment, compared to Embodiment 1, the driving bolt 403 directly abuts against the limiting slider 301, pushing the limiting slider 301 from the first position to the second position. The second mating structure is an inclined surface 5 provided on the side of the limiting slider 301 adjacent to the driving bolt 403.

[0051] In this embodiment, a horizontal opening 10 is provided on the fixing box 11 or the base 2. The wall of the opening 10 has a thread that engages with the drive bolt 403. The threaded section of the drive bolt 403 is threaded into the opening 10, and the front section of the drive bolt 403 abuts against the inclined surface 5 of the limiting slider 301. The user controls the forward and reverse movement of the drive bolt 403 to switch the limiting slider 301 between a first position and a second position. In this embodiment, the drive bolt 403 can also be directly connected to the limiting slider by pulling to drive the limiting slider to move. The pulling relationship can be referred to the structure of the slider and drive bolt 403 in Embodiment 1, and will not be repeated here. The threaded engagement between the drive bolt 403 structure and the cover plate in this embodiment can also use the limiting block 6 structure, specifically referring to the limiting block 6 structure in Embodiment 1, and will not be repeated here.

When the switching slider moves to the unlocked position, it pushes or pulls the limiting slider from the first position to the second position through the first engaging structure. When the switching slider moves to the locked position, the switching slider no longer pushes or pulls the limiting slider, and the limiting slider moves from the second position to the first position.

4. The cover plate mounting structure according to claim 3, characterized in that: It also includes a first reset member located at the end away from the switching slider. When the switching slider no longer abuts against the limiting slider, the first reset member rebounds and pushes the limiting slider from the second position to the first position.

5. The cover plate mounting structure according to claim 3, characterized in that: The driving component includes a driving bolt. One end of the switching slider is rotatably connected to the driving bolt. The driving bolt is threadedly connected to the cover plate or base. By rotating the driving bolt, the driving bolt is displaced, pushing or pulling the switching slider to slide. This causes the switching slider to push or pull the limiting slider from the first position to the second position through the first mating structure. The first mating structure is an inclined surface located at an adjacent end of the switching slider and / or the limiting slider.

6. The cover plate mounting structure according to claim 2, characterized in that: The driving component includes a driving bolt, which is threadedly connected to a cover plate or base. A second mating structure is provided between the driving bolt and the limiting slider. By rotating the driving bolt, the driving bolt is displaced, and the second mating structure causes the driving bolt to push or pull the limiting slider from a first position to a second position.

7. A cover plate mounting structure according to claim 5 or 6, characterized in that: The cover plate or base has an opening, and the driving bolt is movably connected in the opening to drive the limiting slider to move. The wall of the opening has a thread that engages with the threaded drive bolt, or the wall of the opening is a smooth surface. When the wall of the opening is a smooth surface, a limiting block is movably provided on the cover plate or base. The end of the limiting block has an external thread, which can selectively extend into the opening to engage with the driving bolt. The limiting block can switch between a third position and a fourth position. When the limiting block is in the third position, the driving bolt engages with the external thread to achieve a threaded connection. When the limiting block is in the fourth position, the limiting block is separated from the driving bolt. The system also includes a second reset component, which is used to reset the driving bolt when the limiting block is separated from the driving bolt.

8. The cover plate mounting structure according to claim 7, characterized in that: The cover plate has a horizontal opening with a smooth wall. A sliding hole is also provided on the cover plate, and the limiting block is slidably connected within the sliding hole. The sidewall of the opening communicates with the sliding hole. An external thread is located at the top of the limiting block, and the bottom of the limiting block can pass through the sliding hole. The base has a pushing surface for the limiting block. When the cover plate is installed on the base, the bottom of the limiting block is pushed upwards, causing the limiting block to move from the fourth position to the third position. The driving bolt engages with the external thread to achieve a threaded connection. After the cover plate is disassembled, the limiting block moves from the third position to the fourth position by its own weight, elastic force, or magnetic attraction, and the limiting block separates from the driving bolt.

9. A cover plate mounting structure according to claim 8, characterized in that: The cover plate is horizontally arranged with L-shaped or T-shaped fixing boxes. The driving component and the limiting slider are located inside the fixing boxes. The bottom of the fixing boxes is provided with clearance holes corresponding to the through holes. The fixing boxes are provided with through holes corresponding to the location of the driving component. The driving component is driven by extending into the through holes or the driving component extends out of the through holes for easy driving. An operating space corresponding to the through holes is provided between the cover plate and the toilet.

10. A liftable toilet, characterized in that: The toilet seat installation structure includes any one of claims 1-9. The toilet seat includes a cover body and a support plate, and also includes a lifting assembly. The lifting assembly is disposed between the cover body and the support plate and is used to lift the cover body. A locking device is disposed between the support plate and the base and drives the lifting assembly. After the cover body is lifted, an operating space is formed between the cover body and the toilet. The operating space is used to facilitate the driving of the drive component.
