Description

Technical Field

[0001] This invention relates to the field of bathroom accessories technology, specifically to a drain with an anti-loosening structure. Background Technology

[0002] Common drain devices refer to drainage devices installed in places such as bathtubs and washbasins.

[0003] Currently, most drain assemblies on the market use a snap-fit ​​design, consisting of the drain body and end caps, with a drain outlet at the bottom of the drain body. A water seal structure is installed at the bottom of the drain body near the drain outlet to form a water seal. Although the structure is simple, it is prone to loosening during use, and the sealing effect is not ideal.

[0004] When using a drain assembly, a drain pipe is typically connected to the bottom of the drain body, and the through-hole on the drain body is connected to the drain pipe. During use, some impurities may enter the drain assembly through the drain outlet and then enter the drain pipe through the through-hole. If the solid impurities are large, they can easily become stuck inside the drain pipe and cause blockages. Therefore, a reusable drain assembly with an anti-loosening structure is needed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a drain with an anti-loosening structure. The screw fastener has a simple structure and good anti-loosening performance, which can effectively prevent the threaded fastener from loosening due to excessive vibration during use or installation. It also has the advantages of wear resistance and shear resistance, and is suitable for drains in complex environments.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A drain assembly with an anti-loosening structure includes a coaxially arranged upper cover, an inner cup assembly, an outer cup assembly, and a sealing assembly.

[0008] The drainer inner cup assembly includes at least two sets of equally arranged screw-in assemblies. Each screw-in assembly includes a first bolt, a brake block, and a drainer inner cup body. The drainer inner cup assembly passes through the drain outlet of the water container, is sleeved on the drainer outer cup, and is detachably connected to the upper cover.

[0009] The inner wall of the outer cup of the drainer is provided with a limiting groove for preventing rotation, which cooperates with the inner cup assembly of the drainer.

[0010] The brake block of the inner cup assembly of the drainer is installed in the limiting slide groove and screwed to the first bolt, so that the brake block can move linearly along the limiting slide groove under the rotation drive of the first bolt.

[0011] As can be seen from the above description, the design of the limiting slide groove achieves a flexible locking effect and the brake block is highly replaceable. Even if it is damaged during installation and use, it can be replaced in time without replacing the outer cup of the drain, thus saving costs.

[0012] Furthermore, the sealing assembly includes at least a sealing cap, a sealing ring, and a sealing collar.

[0013] The sealing cap is a conical sealing ring and is located between the upper cover and the inner cup assembly of the drainer;

[0014] The sealing ring is disposed between the water container and the inner cup assembly of the drain device;

[0015] The sealing ring is located between the water container and the outer cup of the drain device.

[0016] As can be seen from the above description, the best sealing effect can be achieved by using combined sealing components to separate each part.

[0017] Furthermore, the sealing assembly also includes a water-blocking block, which is disposed on the inner cup of the drainer.

[0018] As can be seen from the above description, the water-blocking block protects the first bolt, preventing it from rusting due to excessive water ingress, and extends the life of the first bolt while providing decoration and sealing.

[0019] Furthermore, a guide block is also provided on the inner wall of the outer cup of the drain device.

[0020] As can be seen from the above description, the guide block guides the inner cup assembly and the outer cup of the drainer to engage and lock together, further preventing loosening.

[0021] Furthermore, an inverted Y-shaped notch is provided below the inner cup of the drainer, and the inverted Y-shaped notch engages with the guide block.

[0022] As can be seen from the above description, by setting the inverted Y-shaped notch, the preset position can be quickly reached while aligning, without the need for time-consuming and laborious alignment.

[0023] Furthermore, each cup in the drainer is equipped with a brake block guide strip. The guide strip is arc-shaped, and the brake block rotates circumferentially along the arc-shaped inner wall of the guide strip under the drive of the first bolt.

[0024] Furthermore, a handle is provided on the top of the cover, and a plurality of protrusions and recesses are provided around the outer periphery of the handle.

[0025] As can be seen from the above description, the friction effect is increased by using several concave and convex parts.

[0026] Furthermore, a second bolt is provided inside the upper cover, and the upper cover is screwed to the inner cup assembly of the drainer via the second bolt.

[0027] Furthermore, the second bolt has a notch, and an extension block is provided below the upper cover.

[0028] A through hole is provided on the side of the extension block, and a third bolt is provided on the through hole to adjust the relative position of the upper cover and the second bolt.

[0029] Furthermore, a side outlet is provided at the bottom of the outer cup of the water container.

[0030] As can be seen from the above description, the side outlet is designed to mimic the function of S-bends on the market, thereby further achieving the odor-proof effect.

[0031] The beneficial effects of this invention are as follows: This application provides a drainer with an anti-loosening structure. The screw fastener has a simple structure and good anti-loosening performance, which can effectively prevent the threaded fastener from loosening due to excessive vibration during use or installation. It also has the advantages of wear resistance and shear resistance, making it suitable for drainers in complex environments. Attached Figure Description

[0052] The brake block 32 of the inner cup assembly 3 of the drainer is installed in the limiting slide groove 42 and screwed with a bolt so that the brake block 32 can move linearly along the limiting slide groove 42 under the rotation drive of the first bolt 31.

[0053] Specifically, the brake block 32 described above is an elongated oval block with a through hole 24 at the concentric point of the arc surface on one side and a threaded structure that matches the first bolt 31. While the first bolt 31 rotates, the brake block 32 moves upward along the axial direction of the first bolt 31 under the rotation restriction of the upper limit slide groove 42 on the inner wall of the drainer outer cup 4 until it is completely engaged in the limit slide groove 42.

[0054] Specifically, the sealing assembly 5 includes at least a sealing cap 51, a sealing ring 52, and a sealing ring 53.

[0055] The sealing cover 51 is a conical sealing ring 52 and is located between the upper cover 2 and the inner cup assembly of the drainer for sealing purposes;

[0056] The sealing ring 52 is located between the water container 6 and the inner cup assembly 3 of the drainer;

[0057] The sealing ring 53 is located between the water container 6 and the outer cup 4 of the drainer.

[0058] Specifically, the sealing assembly 5 also includes a water-blocking block 54, which is disposed on the inner cup 33 of the drainer.

[0059] Specifically, a guide block 43 is also provided on the inner wall of the outer cup 4 of the drainer.

[0060] Specifically, an inverted Y-shaped notch is provided below the inner cup 33 of the drainer, and the inverted Y-shaped notch is engaged with the guide block 43.

[0061] Specifically, each cup 33 inside the drainer is equipped with a brake block 32 and a guide strip 34. The guide strip 34 is arc-shaped, and the brake block 32 rotates circumferentially along the inner wall of the guide strip 34 under the drive of the first bolt 31.

[0062] Specifically, a handle 21 is provided on the top of the cover 2, and a number of protrusions and recesses 23 are provided around the outer periphery of the handle 21.

[0063] Specifically, the upper cover 2 is provided with a second bolt 25, and the upper cover 2 is screwed to the inner cup assembly 3 of the drainer through the second bolt 25.

[0064] Specifically, the second bolt 25 has a notch, and an extension block 22 is provided below the upper cover 2.

[0065] An extension block 22 has a through hole 24 on its side, and a third bolt 26 is provided on the through hole 24 to adjust the relative position of the upper cover 2 and the second bolt 25.

[0066] Specifically, the bottom of the outer cup 4 of the drainer is provided with a side outlet 41.

[0067] Example 2

[0068] An anti-loosening drain valve is similar to that in Embodiment 1, and will not be described again. The drain valve inner cup assembly 3 includes four sets of equally arranged screw-in assemblies.

[0069] This application discloses a drain assembly with an anti-loosening structure. The screw fastener has a simple structure and good anti-loosening performance, which can effectively prevent the threaded fastener from loosening due to excessive vibration during use or installation. It also has the advantages of wear resistance and shear resistance, making it suitable for drain assemblies in complex environments.

[0070] Drain 1 Installation Process

[0071] First, place the bottom sealing ring 53 on the top surface of the outer cup 4 of the drainer, and then place it directly below the drain outlet of the water container 6 such as a bathtub / washbasin;

[0072] Next, the conical sealing ring 52 is fitted onto the inner cup assembly 3 of the drainer, and the whole assembly passes through the drain outlet of the water container 6 and is fitted onto the outer cup 4 of the drainer. Before fitting, the evenly arranged brake blocks 32 need to be placed in a certain direction, and the inverted Y-shaped notch of the inner cup assembly 3 of the drainer is snapped and positioned along the guide block 43.

[0073] Then tighten each of the first bolts 31 clockwise, wherein the brake block 32 is positioned in the limiting slide groove 42 and the first bolts 31 are tightened within the preset range;

[0074] Next, place the top cover 2 and test the drain device 1 with water to observe whether there is any leakage in the water container 6;

[0075] Finally, place the sealing cap 51 and screw on the top cap 2 to complete the installation.

[0076] Principle 2 of drain cover

[0077] Under external force, the drain cover 2 is subjected to torque through the cover handle 21. The third bolt 26 on the extension block 22 drives the second bolt 25 to rotate, thereby connecting it to the drain inner cup assembly 3. When the water container 6 is ready to drain, since the second bolt 25 is locked to the drain inner cup assembly 3, the external force lifts the cover 2 and rotates it at a certain angle, so that the third bolt 26 is locked on the second bolt 25, thus creating a gap between the cover 2 and the drain inner cup assembly 3 for draining. Conversely, when a sealed state is required, the cover 2 is lifted again and rotated at a certain angle, so that the third bolt 26 falls at the notch of the second bolt 25, thus allowing the sealing cap 51 of the cover 2 to fit tightly with the drain inner cup assembly 3 to achieve a sealed water storage function.

[0078] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
