TECHNICAL FIELD

[0001] The present application relates to the technical field of toilet, in particular to a seat ring positioning structure. BACKGROUND

[0002] The toilet seat ring is an important part of the toilet, which is usually composed of a seat ring upper cover and a seat ring lower cover. In order to realize the overall structure of the seat ring, some seat ring upper covers and seat ring lower covers are connected together by adhesion. During use, the toilet is affected by the change of ambient temperature, especially in the environment with large temperature difference, the seat ring material will expand and contract with heat. In order to prevent cracking caused by thermal expansion and contraction, a certain gap is usually required between the seat ring upper cover and the lower cover in the horizontal direction, but during splicing, positional deviation is prone to occur, resulting in adhesion deviation, thereby affecting the appearance and quality of the seat ring.

[0003] Therefore, the present application studies a seat ring positioning structure, which can avoid the mispositioning problem of the seat ring upper and lower covers and improve the appearance and quality of the seat ring. CONTENT OF THE UTILITY MODEL

[0007] By adopting the above technical scheme, the rough positioning between the first cover body and the second cover body can be realized by the cooperation of the positioning ribs and the positioning grooves, the mispositioning of the first cover body and the second cover body during adhesion is avoided, thereby improving the appearance and quality of the seat ring. In addition, during use, the toilet cover plate will expand and contract with heat due to material reasons, such as UF material, the first cover body and the second cover body may be slightly deformed, at this time, the positioning ribs will be broken under the action of external force, thereby avoiding the cracking of the first cover body and the second cover body due to excessive restriction, and prolonging the service life of the seat ring.

[0008] Optionally, the positioning grooves and the positioning ribs are shaped to match each other, and the positioning ribs are in the shape of a circular truncated cone.

[0009] By adopting the technical scheme, the positioning rib in the shape of a circular truncated cone can be more smoothly inserted into the positioning groove for positioning, and in the process of thermal expansion and cold contraction, the circular truncated cone shape makes the positioning rib more easily broken.

[0010] Optionally, an active gap is arranged between the bottom surface of the positioning groove and the mounting surface of the positioning rib.

[0011] Optionally, the positioning structure further comprises a plurality of protrusions arranged on the first cover body, the second cover body is provided with a plurality of grooves corresponding to the protrusions, the protrusions extend into the grooves, and the size of the protrusions is smaller than that of the grooves.

[0012] By adopting the technical scheme, through the cooperation of the protrusions and the grooves, the coarse positioning between the first cover body and the second cover body can be further achieved, and the bonding position between the first cover body and the second cover body is more accurate.

[0016] By adopting the technical scheme, the first cover body and the second cover body can be limited in the upward and downward directions, and due to thermal expansion and cold contraction generated during use, the diameter of the through hole is greater than the diameter of the screw rod of the bolt and smaller than the diameter of the nut, which can give the possibility of relative left and right movement between the cover plates, and the left and right movement is not limited, so that the first cover body and the second cover body are prevented from cracking due to position limitation, and the service life of the seat ring is better improved.

[0017] Optionally, a soft gasket is further included, the soft gasket penetrates the bolt, and when installed, the soft gasket abuts between the bolt and the first cover body.

[0018] Optionally, the positioning rib and the positioning groove comprise at least two groups, and at least one group of the positioning grooves has a size length along the length direction of the cover body greater than that of the positioning rib.

[0034] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0035] This application discloses a seat ring positioning structure. (Refer to...) Figure 1 , Figure 2 and Figure 6 The seat ring positioning structure includes a first cover 1 and a second cover 2. In this embodiment, the first cover 1 is the lower cover of the seat ring, and the second cover 2 is the upper cover of the seat ring. In other embodiments, the first cover 1 can also be the upper cover of the seat ring, in which case the second cover 2 is the lower cover of the seat ring. The first cover 1 and the second cover 2 are assembled to form the seat ring. A positioning structure is provided between the first cover 1 and the second cover 2 for preliminary positioning when the first cover 1 and the second cover 2 are assembled. The positioning structure includes several positioning ribs 3 provided on the first cover 1. In this embodiment, positioning ribs 3 are provided on both opposite sides of the length direction of the first cover 1, and positioning grooves 4 are opened on the second cover 2 at positions corresponding to the positioning ribs 3. During installation, the positioning ribs 3 are inserted into the positioning grooves 4 to achieve positioning between the first cover 1 and the second cover 2, so that the first cover 1 and the second cover 2 can be easily aligned during bonding, making the bonding position accurate and better ensuring the aesthetics of the seat ring.

[0036] Furthermore, during use, when the toilet seat expands and contracts due to the material, the first cover 1 and the second cover 2 will shift in the horizontal direction, and the positioning rib 3 will break under external force. This prevents the positioning rib 3 from restricting the relative movement between the first cover 1 and the second cover 2, thus better protecting the seat ring and extending its service life.

[0037] In some embodiments, the positioning groove 4 is adapted to the shape of the positioning rib 3, which has a frustum-shaped structure. The frustum-shaped positioning rib 3 is more prone to breakage during use, thus better protecting the toilet seat. The positioning rib 3 can be made of a easily breakable material to further ensure it breaks under external force. The adaptation of the positioning groove 4 to the positioning rib 3 makes assembly more accurate and convenient. This adaptation includes the positioning groove 4 being at least identical to the head shape of the positioning rib 3. Due to the material of the toilet seat, such as UF material, the toilet is easily affected by temperature changes during use, resulting in thermal expansion and contraction. Therefore, a gap needs to be left at the joint. Ultimately, during use, the upper and lower covers of the toilet seat will inevitably shift horizontally. If the upper and lower covers are locked in the left and right directions, coupled with thermal expansion and contraction, the toilet seat is very likely to crack. Therefore, in this design, the positioning rib 3 has a frustum-shaped structure, and the positioning rib 3 as a whole has a weak point, making it easier to break during later use and less likely to cause cracking of the toilet seat.

[0038] Reference Figure 7 In some embodiments, a movable gap 14 is provided between the bottom surface of the positioning groove 4 and the mounting surface of the positioning rib 3. In this embodiment, one end of the positioning rib 3 is fixed to the first cover plate 1, and the other end is fixed in the positioning groove 4, leaving a movable gap 14 in the middle. This allows the two ends of the positioning rib 3, which are fixed to the upper and lower parts, to be staggered in the left and right directions when the upper and lower covers move relative to each other, thereby preventing breakage and protecting the cover plate.

[0039] Reference Figure 2 and Figure 3 In some embodiments, the positioning structure further includes a plurality of protrusions 5 disposed on the first cover 1, with the protrusions 5 evenly spaced along the periphery of the first cover 1. The second cover 2 is provided with a plurality of grooves 6 corresponding to the protrusions 5. The protrusions can be either dot-shaped or block-shaped. Coarse positioning is achieved through the cooperation of the protrusions 5 and the grooves 6, and the size of the protrusions 5 is smaller than that of the grooves 6, so that they do not lock the first cover 1 and the second cover 2 in the left-right direction, making it less likely for the toilet seat to crack during later use.

[0040] In some embodiments, a plurality of protrusions 5 on the first cover 1 are arranged around the inner and / or outer rings of the first cover 1, and the second cover 2 includes an annular platform 15 arranged along the inner and / or outer rings, and a plurality of the grooves 6 are formed on the annular platform 15.

[0041] Reference Figure 3 In some embodiments, a locking structure is also included, which further includes a bolt 7. The first cover 1 has a through hole 9, and the second cover 2 has a threaded hole 8. The bolt 7 passes through the through hole 9 and is screwed into the threaded hole 8.

[0042] In some embodiments, the diameter of the through hole 9 is larger than the diameter of the bolt 7's threaded shaft but smaller than the diameter of the nut. During installation, the nut of the bolt 7 abuts against the side of the first cover 1 away from the second cover 2, and the threaded shaft of the bolt 7 passes through the through hole 9 and is screwed into the threaded hole 8. The fact that the diameter of the through hole 9 is larger than the diameter of the bolt 7's threaded shaft but smaller than the diameter of the nut allows the bolt 7 to lock the cover in the vertical direction without restricting the relative movement between the covers in the horizontal direction.

[0043] In some embodiments, the seat ring positioning structure further includes a soft pad, which is inserted through the bolt 7 and abuts against the bolt 7 and the first cover 1 during installation.

[0044] Reference Figure 2 and Figure 3 In some embodiments, the second cover 2 has a plurality of threaded holes 8 along the circumferential direction, and the first cover 1 has through holes 9 corresponding to the threaded holes 8. The bolts 7 pass through the through holes 9 and are screwed into the threaded holes 8.

[0045] Reference Figure 5 In some embodiments, the side of the first cover 1 facing away from the second cover 2 is also provided with an anti-slip pad 10.

[0046] Reference Figure 2 In some embodiments, the positioning ribs 3 and positioning grooves 4 include at least two sets, wherein at least one set of positioning grooves 4 has a length along the length of the cover body that is greater than the size of the positioning ribs 3. Specifically, the opening length of the positioning grooves 4 along the length of the cover body is greater than the length of the positioning ribs 3 along the length of the cover body. In this embodiment, it includes two sets of positioning ribs 3 and positioning grooves 4 that cooperate with them along the length of the first cover plate 1. In this embodiment, the positioning ribs 3 are frustum-shaped, wherein the positioning grooves 4 located on the upper part of the first cover plate 1 are circular, and the diameter is the same as the end of the positioning ribs 3. The other set of positioning grooves 4 are elliptical, and the left and right widths of the positioning grooves 4 are the same as the diameter of the positioning ribs 3. The length of the positioning grooves 4 is greater than the diameter of the positioning ribs 3, so that they can move in the vertical direction, thereby increasing the tolerance rate during assembly of the cover plates in case of mismatch in the vertical direction due to changes in production or materials.

[0047] In some embodiments, the first cover 1 and the second cover 2 are joined together to form a seat ring, and there is a gap at the horizontal joint between the first cover 1 and the second cover 2.

[0048] Reference Figure 4 In this embodiment, a ball joint structure 12 is provided next to the positioning rib 3. The ball joint structure 12 is installed in the structural cavity 11, which is filled with glue. Soft glue 13 is also provided on the ball joint structure 12. During use, the ball joint structure 12 will swing as the cover plate moves, which is prior art and will not be described in detail.

[0049] The implementation principle of the seat ring positioning structure in this application embodiment is as follows: by coordinating the positioning rib 3 and the positioning groove 4, coarse positioning between the first cover 1 and the second cover 2 can be achieved, avoiding misalignment of the first cover 1 and the second cover 2 during bonding, thereby improving the aesthetics and quality of the seat ring. Furthermore, during use, the toilet seat will undergo thermal expansion and contraction due to the material, and the first cover 1 and the second cover 2 may undergo slight deformation. At this time, under the action of external force, the positioning rib 3 will break, preventing the first cover 1 and the second cover 2 from cracking due to excessive restriction, thereby extending the service life of the seat ring.
