Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a hinge structure and a toilet seat. Background Technology

[0002] Flush toilets, as a common sanitary fixture, have long been widely used in people's daily lives. However, there are some technical problems with the existing toilet hinge structure and the way the toilet seat is connected.

[0003] On the one hand, many designs rely on the tightening force of screws to provide the connection strength between the hinge and the seat. This connection method cannot provide sufficient stability when the toilet seat is subjected to significant external forces, easily leading to loosening or even damage of the connection between the hinge and the seat, thus affecting the product's lifespan and reliability. On the other hand, when the assembly of the hinge and seat requires side locking, special tools are usually needed for assembly, which not only increases the complexity of the manufacturing process but also reduces production efficiency and increases production costs.

Detailed Implementation

[0031] Example 1

[0032] The following is combined with Figures 1-6 This utility model will be described in detail.

[0033] A hinge structure, such as Figures 2-5 As shown, it includes a hinge body 20, the first end of which is rotatably or fixedly connected to a base 10 provided on the cover plate; it also includes a pin 40, which passes through the first end of the hinge body 20 and the base 10 to restrict the hinge body 20 from detaching from the base 10. Compared with the traditional side locking method, the method of using the pin 40 to restrict the hinge body 20 from detaching from the base 10 does not require the use of special tools for assembly, thus reducing the complexity of the production process.

[0034] Furthermore, a fixing block 30 is provided on the outside of the base 10. The fixing block 30 abuts against both sides of the pin 40 to prevent the pin 40 from detaching from the base 10. This ensures that the pin 40 is always firmly fixed at the connection between the base 10 and the connector, thereby significantly enhancing the connection strength between the base 10 and the hinge body 20. Even under the action of a large external force, the hinge structure can remain stable, avoiding loosening or damage to the connection, and improving the reliability and service life of the product.

[0035] In this embodiment, the fixing block 30 is provided with a groove 301 to accommodate the base 10, reducing displacement of the base 10 caused by external forces or vibrations during use. The portions of the fixing block 30 located on both sides of the groove 301 constitute limiting portions 302, which abut against both sides of the pin 40, ensuring that the pin 40 is always firmly fixed at the connection between the base 10 and the connector, thereby significantly enhancing the connection strength between the base 10 and the hinge body 20. Both the groove 301 and the base 10 have smoothly transitioning chamfered structures, reducing friction at the connection between the groove 301 and the base 10, making the assembly process of the base 10 and the fixing block 30 smoother.

[0036] Furthermore, the limiting part 302 includes limiting protrusions 3021 provided on both sides of the groove 301. The limiting protrusions 3021 are provided with abutting surfaces. The two abutting surfaces are arranged opposite to each other, so that the two ends of the pin 40 can be stably abutted against the abutting surfaces to prevent them from falling off the base 10.

[0037] Specifically, the limiting protrusion 3021 has a chamfered structure at its edge, which facilitates the insertion of the fixing block 30 into the base 10.

[0038] like Figure 3 and Figure 5As shown, the base 10 has a first connecting position 501, and the fixing block 30 has a second connecting position 502. The first connecting position 501 and the second connecting position 502 are connected to each other by fasteners 60, thereby connecting the fixing block 30 to the base 10. When it is necessary to replace or repair the hinge components, the fixing block 30 can be easily removed by simply loosening the fasteners 60 for necessary maintenance or replacement. Furthermore, the base 10 has two first connecting positions 501 on its left and right sides, and the fixing block 30 has two corresponding second connecting positions 502 on its left and right sides. The double connecting position connection structure can improve the overall structural strength of the hinge structure, enabling it to withstand greater loads and external forces, thereby extending the service life of the hinge.

[0039] Specifically, the first connection position 501 has a V-shaped structure, which can make the connection between the base 10 and the fixing block 30 evenly stressed, reducing the loosening or damage of the connection caused by excessive local stress.

[0040] In other embodiments, the first connection position 501 may be a U-shaped structure or a trapezoidal structure, or other structural designs that can make the force at the connection point uniform.

[0041] In this embodiment, the fixing block 30 is provided with a countersunk groove 303, which can accommodate the fastener 60 and increase the aesthetics of the hinge structure.

[0042] like Figure 6 As shown, the hinge body 20 includes a connecting part 201, a pivot part 202, and a bent arm 203 disposed between the connecting part 201 and the pivot part 202. The connecting part 201 is connected to the base 10, and the pivot part 202 is rotatably connected to the base of the toilet seat 110. The bent arm 203 protrudes in a direction away from the base 10.

[0043] Furthermore, the base 10 is provided with a insertion groove 101, and the connecting part 201 of the hinge body 20 is inserted into the insertion groove 101. The insertion groove 101 is provided with a first shaft hole 701, and the connecting part 201 is provided with a second shaft hole 702. The first shaft hole 701 and the second shaft hole 702 are coaxially arranged, and a pin 40 is laterally inserted through the first shaft hole 701 and the second shaft hole 702. The coaxial arrangement of the first shaft hole 701 and the second shaft hole 702 ensures the accuracy of the connection, simplifies the assembly process of the base 10 and the hinge body 20, and improves production efficiency.

[0044] Specifically, the insertion slot 101 has a first guide surface 801 at one end near the connecting part 201, and the connecting part 201 has a second guide surface 802 at the end near the base 10, which can abut against the first guide surface 801. The design of the first guide surface 801 and the second guide surface 802 can guide the connecting part 201 to smoothly insert into the insertion slot 101. This guiding effect makes the assembly process smoother, reduces the assembly difficulty, and improves the assembly efficiency. The second guide surface 802 is a slope. The slope design allows the insertion protrusion to smoothly enter during the assembly process with the insertion slot 101, reducing friction and reducing wear between components.

[0045] In this embodiment, a limiting flange 2031 is provided at one end of the bent arm 203 near the connecting part 201. The limiting flange 2031 can abut against the base 10 to limit the installation depth of the connecting part 201.

[0046] In this embodiment, the hinge structure also includes a decorative element 90. The decorative element 90 has a first mounting position 1001, and the fixing block 30 has a second mounting position 1002. The first mounting position 1001 and the second mounting position 1002 are connected by a concave-convex connection, so that the decorative element 90 is connected to the fixing block 30. The decorative element 90 has a connecting groove 901, which can accommodate the base 10. The decorative element 90 can conceal the mechanical structure of the hinge structure, making the entire hinge structure look neater, more refined and beautiful.

[0047] Specifically, the first mounting position 1001 is a mounting protrusion, and the second mounting position 1002 is a mounting groove. The second mounting groove is provided with a spring piece, which can provide continuous elastic support and reduce structural instability caused by loose connection.

[0048] The installation principle of the hinge structure provided in this embodiment is as follows:

[0049] The connecting part 201 of the hinge body 20 is connected to the insertion slot 101 of the base 10, and the pin 40 is laterally inserted into the first shaft hole 701 and the second shaft hole 702 to fix the hinge body 20 and the base 10. Then, the groove 301 of the fixing block 30 is installed on the base 10, and the fastener 60 is inserted into the first connecting position 501 and the second connecting position 502 to strengthen the connection between the fixing block 30 and the base 10. Finally, the decorative part 90 is connected to the fixing block 30 through the concave-convex connection between the first mounting position 1001 and the second mounting position 1002. At this point, the hinge structure is installed. The installed hinge structure has a rectangular shape with simple lines, reducing the exposed mechanical structure and making the product appearance more refined.

[0050] Example 2

[0051] like Figure 7As shown, this embodiment provides a toilet seat 110, including a base (not shown) and a seat body 1101. The two sides of the seat body 1101 are connected to hinge structures as described above. A connecting part 201 is connected to a base 10, and a pivot part 202 is rotatably connected to the base. Due to the stability of the hinge structure and the connecting structure, a secure connection between the toilet seat 110 and the toilet seat ring is ensured, reducing the risk of the toilet seat 110 loosening or falling off.
