[0034] The central shaft 6 has counterweights 8 installed in the slots on both sides, a shaft connecting seat 1 sleeved at the front end, a shaft housing 7 sleeved in the middle, and a base connecting seat 5 sleeved at the rear end. The central shaft 6 is inserted into the outer housing 2 and tightly connected.

[0035] The shaft connecting seat 1 consists of a shaft core 101 sleeved on the front end of the central shaft 6 and a shaft seat protective shell 102 threadedly connected to the shaft core 101. The rear end of the shaft seat protective shell 102 is connected to the outer shell 2, so that the toilet seat shaft connected to the shaft core 101 is slowly lowered due to the influence of the thread.

[0036] Through the above technical solution, and the reasonable coordination of components such as the central shaft, shaft connecting seat, and outer shell, the structure is simple and compact, which greatly reduces the production and assembly costs compared to existing complex dampers. The shaft connecting seat adopts a threaded connection between the shaft core and the shaft seat protective shell, which allows the toilet seat shaft to achieve stable and slow descent due to the influence of the thread, effectively avoiding the problem of the toilet seat falling suddenly. The positioning block set on the side of the outer shell facilitates the accurate and quick installation of the damper into the toilet shaft, improving installation efficiency and reducing installation costs and time costs.

[0037] The outer shell 2 is fitted with the outer shell 3 and the inner shell 4. The inner shell 4 is snapped to the right end of the base connecting seat 5. The right end of the base connecting seat 5 is fixedly connected to the damping spring 9. The inner shell 4 fits the damping spring 9 inside. The right end of the inner shell 4 is fitted with a cover 10.

[0038] The cover 10 is used to press the inner shell 4 down along the base connecting seat 5, and the outer shell 3 covers the connection between the inner shell 4 and the base connecting seat 5, and is opposite to the hole of the base connecting seat 5.

[0039] The base connecting seat 5 has buckles 501 on both sides, and the inner shell 4 has rectangular slots 401 on both sides. The buckles 501 are inserted into the slots 401, and the slots 401 allow the inner shell 4 to move linearly.

[0040] The base connecting seat 5 has a connecting hole 301 on its side, which is used to connect with the toilet shaft seat pin. The inner shell 4 has an intercepting groove on its side, which is blocked inside the connecting hole 301 by the rebound force of the damping spring 9, thus blocking the pin of the toilet shaft seat. The outer shell 2 has a positioning block 201 on its side, which is used to install into the toilet shaft.

[0041] The outer shell 2 is fitted onto the shaft shell 7, and its inner wall is tightly fitted with the central shaft 6 of the mounting balance block 8, and fixes the shaft seat protective shell 102, so that the shaft core 101 can rotate within the shaft seat protective shell 102; the shaft core 101 of the shaft connecting seat 1 is provided with a regular hexagonal connecting groove for connecting with the toilet seat.

[0042] Both the outer shell 3 and the cover 10 are made of 304 stainless steel; the damping spring 9 installed on the cover 10 is a conical spring.

[0043] It has good corrosion resistance, wear resistance and strength, and can adapt to the humid environment of the bathroom. It is not easy to rust or be damaged, thus extending the service life of the product. The damping spring installed on the cover is a conical spring. Compared with ordinary springs, conical springs have better stability and elasticity during compression and extension, and can provide more uniform and stable damping force, further improving the performance and reliability of the damper.

[0044] For further technical solutions, please refer to Figure 10 and Figure 11 As shown, the inside of the bearing housing 102 is also provided with a linear slide groove.

A spring piece 104 is fixedly connected between the arc-shaped slide piece 103 and the bearing housing 102 to generate frictional damping. Through this technical solution, by keeping the spring piece 104 in a pre-compressed state, it plays the role of frictional damping. Combined with the threaded damping, it achieves a double damping effect and plays a role in slow descent.

[0045] This application features a simple and compact structure achieved through the rational combination of components such as the central shaft, shaft connecting seat, and outer shell. Compared to existing dampers with complex structures, this significantly reduces production and assembly costs. The shaft connecting seat uses a threaded connection between the shaft core and the protective shell, allowing the toilet seat shaft to achieve stable and slow descent due to the thread, effectively preventing the toilet seat from falling erratically. The positioning block on the side of the outer shell facilitates precise and quick installation of the damper into the toilet seat shaft, improving installation efficiency and reducing installation and time costs.

[0046] The base connector is connected to the inner shell via a snap-fit ​​mechanism, and the slot defines the movement trajectory of the inner shell. This connection method is not only convenient to install, but also easy to operate when disassembly and maintenance are required, greatly improving the maintainability of the product. The connecting hole on the side of the base connector connects to the toilet bearing pin, while the intercepting groove on the side of the inner shell is locked inside the connecting hole under the action of the damping spring, locking the pin of the toilet bearing. This dual connection method ensures the firmness and stability of the connection between the damper and the toilet bearing. The outer shell and the cover are made of 304 stainless steel, which has good corrosion resistance, wear resistance and strength, can adapt to the humid environment of the bathroom, is not easy to rust or be damaged, and extends the service life of the product.

[0047] The damping spring installed on the cover is a conical spring. Compared with ordinary springs, conical springs have better stability and elasticity during compression and extension, and can provide more uniform and stable damping force, further improving the performance and reliability of the damper.
