[0023] 1. By providing a push block inside the connecting pipe and a connecting sleeve for the cover plate assembly, and by setting a first abutting part and a second abutting part between the push block and the connecting sleeve for mutual abutting and transmission cooperation, the push block can be driven to engage or disengage with the mating part on the support during the rotation of the cover plate assembly, thereby realizing the locking and unlocking of the cover plate assembly. When the cover plate assembly needs to be removed, simply open the cover plate assembly to the preset angle range and pull the cover plate assembly upwards. There is no need to disassemble the bolts and nuts. The disassembly and assembly are convenient and time-saving, and the structure is simple with fewer parts, which can effectively reduce costs.

[0024] 2. By designing the first and second abutting parts as bosses and gradually changing boss slopes, the bosses and gradually changing boss slopes can move smoothly, ensuring that the push block can smoothly switch between the locking and unlocking positions.

[0025] 3. An elastic element chamber for placing elastic elements is provided at the top of the outer periphery of the anti-rotation shaft, making reasonable use of the anti-rotation shaft space, with an effective layout and compact structure.

[0026] 4. The connecting sleeve is placed on the damper housing. Since the damper has a housing and shaft that can rotate relative to each other, there is no need to design additional space to accommodate the connecting sleeve, resulting in a compact structure. Attached Figure Description

[0052] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0053] First embodiment:

[0054] Reference Figures 1 to 12 The first preferred embodiment of this utility model is a toilet seat quick-release structure that unlocks at a predetermined angle, including a seat assembly 10, a support 20, a push block 30, a connecting sleeve 40, a connecting pipe 50, etc.

[0055] Among them, see Figure 3 The cover assembly 10 includes a toilet cover 11 and a toilet seat 12. The rear end of the toilet cover 11 is provided with a toilet cover bushing 111, and the rear end of the toilet seat 12 is provided with a toilet seat bushing 121.

[0056] The connecting pipe 50 is rotatably connected to the rear end of the cover assembly 10. Specifically, two toilet cover bushings 111 and two toilet seat bushings 121 are respectively provided and rotatably connected to the left and right ends of the connecting pipe 50. The connecting pipe 50 is a round pipe. The toilet cover bushings 111 and two toilet seat bushings 121 are coaxially arranged with the connecting pipe 50. The anti-rotation shaft 60 and the damper 80 described below cooperate to form an integrated rotating shaft, which is simultaneously sleeved in the toilet cover bushing 111, the toilet seat bushing 121 and the connecting pipe 50. That is, the toilet cover bushing 111, the toilet seat bushing 121 and the connecting pipe 50 are coaxially arranged through this integrated rotating shaft. The anti-rotation shaft 60 in the integrated rotating shaft is located in the connecting pipe 50 and cannot be rotated. The damper 80 in the integrated rotating shaft is located in the toilet cover bushing 111 and the toilet seat bushing 121. During the flipping process of the cover assembly 10, the cover bushing 111 and the seat bushing 121 rotate around the integrated rotating shaft, and thus rotate relative to the connecting pipe 50.

[0057] One end of the support 20 is fixed to the toilet seat (not shown), and the other end is provided with a mating part 21. The mating part 21 of the support 20 is inserted into the connecting pipe 50. Specifically, the support 20 includes a disc-shaped disc part 22 and a plug shaft 21. The disc part 22 is fixed to the toilet seat by fastening components such as bolts and nuts. The plug shaft 21 is the mating part 21 and is provided with a groove 23.

[0058] The push block 30 is movably disposed within the connecting pipe 50 and can move between a locked position and an unlocked position. The push block 30 is provided with a first abutment part 31 and a locking part 32. When the push block 30 is in the locked position, the locking part 32 can engage with the mating part 21. When the push block 30 is in the unlocked position, the locking part 32 can disengage from the mating part 21. Specifically, the locking part 32 is a locking block, the mating part 21 is the insertion shaft 21 of the support, and the locking block is the edge of a locking hole on the push block 30; the insertion shaft 21 is provided with a locking groove 23. When the insert shaft 21 passes through the card hole, the card block and the card slot 23 are on the same horizontal plane. When the push block 30 is in the unlock position, the card block exits the card slot 23, thereby releasing the restriction on the mating part 21 of the support 20, so that the cover plate assembly 10 can be pulled out relative to the support 20. When the push block 30 is in the locking position, the card block is inserted into the card slot 23, thereby limiting the mating part 21 of the support 20, realizing the locking of the cover plate assembly 10 and the support 20.

[0059] The connecting sleeve 40 is circumferentially limited on the cover assembly 10 and rotates with the cover assembly 10. The connecting sleeve 40 is provided with a second abutment portion 41. Specifically, the connecting sleeve 40 is disposed within the bushings (including the toilet cover bushing 111 and the toilet seat bushing 121) of the cover assembly 10, so that the connecting sleeve 40 can be synchronously rotated when the cover assembly 10 rotates. Specifically, in this embodiment, the connecting sleeve 40 is circumferentially limited to the toilet seat bushing 121 but circumferentially rotatable to the toilet cover bushing 111. That is, the connecting sleeve 40 rotates due to the rotation of the toilet seat 12, and the rotation of the connecting sleeve 40 is not controlled by the toilet cover 11. In other embodiments, the connecting sleeve 40 may also be circumferentially limited to the toilet cover bushing 111 but circumferentially rotatable to the toilet seat bushing 121. That is, the connecting sleeve 40 rotates due to the rotation of the toilet cover 11, and the rotation of the connecting sleeve 40 is not controlled by the toilet seat 12. The connecting sleeve 40 can be selected to rotate either driven by the toilet cover 11 or by the toilet seat 12, depending on the needs; the effect is the same.

[0060] The shape of the connecting sleeve 40 can be designed as needed, see [reference]. Figure 3 The shapes of the connecting sleeves 40 on the left and right sides are different, and the end face of the connecting sleeve 40 is provided with a second abutment part 41.

[0061] Among them, reference Figure 10 , Figure 11 and Figure 12 The cover plate assembly 10 rotates to a preset angle α (defined in this invention as the angle of the cover plate assembly 10 relative to the horizontal plane, see [reference]). Figure 12 When the first abutting part 31 and the second abutting part 41 abut against each other, the push block 30 moves to the unlocked position; (Reference) Figure 8 and Figure 9 When the cover plate assembly 10 rotates to a non-preset angle, the first abutting part 31 and the second abutting part 41 separate, and the push block 30 returns to the locking position.

[0062] By providing a push block 30 inside the connecting pipe 50 and a connecting sleeve 40 for the cover plate assembly 10, and by providing a first abutting part 31 and a second abutting part 41 between the push block 30 and the connecting sleeve 40 for mutual abutment and transmission, the push block 30 can be driven to engage or disengage with the mating part 21 on the support 20 during the rotation of the cover plate assembly 10, thereby achieving the locking and unlocking of the cover plate assembly 10. When the cover plate assembly 10 needs to be removed, it is only necessary to open the cover plate assembly 10 to a preset angle range and pull the cover plate assembly 10 upwards. There is no need to disassemble the bolts and nuts, making disassembly and assembly convenient and time-saving. In addition, there are fewer parts and the structure is simple, which can effectively reduce costs.

[0063] Preferred, Reference Figure 3 , Figure 4The first abutment part 31 is a gradually tapered protruding slope, and the second abutment part 41 is a protrusion. When the cover plate assembly 10 rotates to a preset angle α, the protrusion moves along the protruding slope until it abuts against the most protruding part of the protruding slope. Figure 10 As shown. This drives the push block 30 to move to the unlocked position. Of course, the first abutment 31 is a boss, and the second abutment 41 is a gradually changing boss slope, which can also achieve transmission cooperation. The boss and the gradually changing boss slope can move smoothly, ensuring that the push block 30 smoothly switches between the locked and unlocked positions.

[0064] Furthermore, an anti-rotation shaft 60 is installed inside the connecting pipe 50. The anti-rotation shaft 60 has a transverse cavity 61 and a vertical cavity 62 that are connected. The push block 30 can slide in the transverse cavity 61, and the mating part 21 of the support 20 can be inserted and removed from the vertical cavity 62 to realize the fixing and disassembly of the cover plate assembly 10 and the support 20.

[0065] In this embodiment, reference Figure 5 The top of the outer periphery of the anti-rotation shaft 60 is provided with an elastic element chamber 63, which is used to house the elastic element 70. One end of the elastic element 70 abuts against the wall of the elastic element chamber, and the other end abuts against the push block 30. The push block 30 can be reset under the elastic force of the elastic element 70. When the first abutting part 31 and the second abutting part 41 separate, the push block 30 is reset to the locked position under the elastic force of the elastic element 70.

[0066] In this embodiment, a damper 80 is also included. The damper 80 includes a rotating shaft 81 and a housing 82 that are rotatably coupled to each other. The rotating shaft 81 of the damper 80 is axially inserted into one end of the anti-rotation shaft 60 and circumferentially limited; the housing 82 is axially inserted into the connecting sleeve 40 and circumferentially limited. The structure of the damper 80 is prior art in the art, and it is used to realize the slow-descent function of the cover plate assembly, which will not be described in detail here.

[0067] In this embodiment, reference Figure 5 and Figure 7 The push block 30 includes a first plate 35 and a second plate 33 connected to each other. A first abutting part 31 is provided on the outer wall of the first plate 35 and protrudes towards the connecting sleeve 40, and a snap-fit ​​part 32 is provided on the second plate 33. The first plate 35 and the second plate 33 are connected by a connecting plate 34.

[0068] In this embodiment, the preset angle α is preferably in the range of 60 degrees to 90 degrees, which facilitates the user in removing the cover assembly 10. Of course, it can be understood that the preset angle α can also be the entire working angle of the cover assembly 10. For example, the cover assembly 10 can be flipped between 0 degrees and 110 degrees, and the preset angle α can be any angle between 0 degrees and 110 degrees, such as 0 degrees, 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, 90 degrees, 100 degrees, 110 degrees, etc.

[0069] In this embodiment, there are two supports 20, each cooperating with a socket (not shown) on both sides of the connecting pipe 50. There are two push blocks 30, each movably disposed within both sides of the connecting pipe 50. There are two connecting sleeves 40, each located on both sides of the rear end of the cover assembly 10. Correspondingly, there are also two anti-rotation shafts 60, elastic elements 70, and dampers 80. The rear end bushings of the cover assembly 10 on both sides of the connecting pipe 50 (including the toilet cover bushing 111 and the toilet seat bushing 121), supports 20, push blocks 30, connecting sleeves 40, anti-rotation shafts 60, elastic elements 70, and dampers 80 form two independent disassembly and assembly structures.

[0070] The disassembly and assembly process in this embodiment is as follows:

[0071] When disassembling cover assembly 10, refer to Figure 10 , Figure 11 and Figure 12 When the cover plate assembly 10 is opened to a preset angle a, which is 90 degrees, the cover plate assembly 10 drives the connecting sleeve 40 to rotate. The boss on the connecting sleeve 40 engages with the inclined surface of the boss on the push block 30. The boss moves along the inclined surface until it abuts against the most protruding part of the inclined surface, pushing the push block 30 open. Then, the locking block of the push block 30 exits the slot 23 on the insertion shaft 21 of the support 20, thereby releasing the restriction on the insertion shaft 21 of the support 20. The cover plate assembly 10 can then be pulled out relative to the support 20.

[0072] When installing cover plate assembly 10, refer to Figure 8 and Figure 9 The cover plate assembly 10 and the connecting pipe 50 are assembled into one piece, so that the angle between the cover plate assembly 10 and the connecting pipe 50 is maintained at a preset angle a (i.e., the angle in the disassembled state). The insertion shaft 21 of the support 20 is inserted into the anti-rotation shaft 60 in the connecting pipe 50. Then the cover plate assembly 10 is rotated to a non-preset angle. The cover plate assembly 10 drives the connecting sleeve 40 to rotate. The boss on the connecting sleeve 40 and the boss slope of the push block 30 gradually separate. The push block 30 is reset to the locking position under the elastic force of the elastic element 70. The locking block is locked into the slot 23 of the insertion shaft 21. Then the push block 30 limits the insertion shaft 21 of the support 20 to achieve the locking of the cover plate assembly 10 and the support 20.

[0073] Second embodiment:

[0074] See Figure 13The second preferred embodiment of this utility model provides a quick-release structure for a toilet seat that unlocks at a predetermined angle. The main difference between this structure and the first preferred embodiment is that in the first embodiment, the connecting sleeve 40 is independently manufactured and circumferentially fitted within the toilet seat bushing 111 and the toilet seat bushing 121. In this embodiment, however, the toilet seat bushing 111 or the toilet seat bushing 121 is directly formed as the connecting sleeve 40. That is, the connecting sleeve 40 is not manufactured separately; instead, the toilet seat bushing 111 or the toilet seat bushing 121 serves as the connecting sleeve 40. This eliminates the need for separate manufacturing and assembly of the connecting sleeve 40, thereby reducing material costs and assembly steps. Specifically, in this embodiment, the toilet seat bushing 111 also serves as the connecting sleeve 40; that is, a second abutment portion 41 is provided on the end face of the toilet seat bushing 111. Of course, in other embodiments, a second abutment portion 41 may be provided on the end face of the toilet seat bushing 121. In this case, the axial positions of the toilet cover bushing 111 and the toilet seat bushing 121 may be reversed.

[0075] Third embodiment:

[0076] See Figure 14 The main difference between the third preferred embodiment of this utility model and the first preferred embodiment of a toilet seat quick-release structure with a predetermined unlocking angle is that in the first embodiment, when the push block 30 is in the unlocked position, the locking part 32 on the push block 30 completely exits the slot 23 on the insert shaft 21, and the insert shaft 21 does not contact the locking part 32 on the push block 30 during the process of exiting the vertical cavity 62 of the anti-rotation shaft 60. In this embodiment, it is preferable to design the upper groove wall of the slot 23 of the insert shaft 21 to include a horizontal groove wall 231 and an inclined groove wall 232, with the inclined groove wall 232 located outside the horizontal groove wall 231. When the push block 30 is in the locked position, the locking part 32 on the push block 30 engages with the horizontal groove wall 231, and the insert shaft 21 cannot be pulled out at this time. When the push block 30 is in the unlocked position, the locking part 32 on the push block 30 does not completely exit the slot 23 on the insert shaft 21. The locking part 32 engages with the inclined groove wall 232. During the process of the insert shaft 21 exiting the vertical cavity 62 of the anti-rotation shaft 60, a certain force needs to be applied in order to exit the vertical cavity 62 under the guidance of the inclined groove wall 232. This design, which requires a certain force to pull out the insert shaft 21, can effectively prevent accidental disassembly of the cover plate assembly 10.

[0077] This utility model also proposes a toilet, including a seat assembly 10 and a toilet seat (not shown), and also includes a quick-release structure for unlocking the toilet seat at a predetermined angle as described in any of the above.

As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
