Description

Technical Field

[0001] This utility model relates to the field of bathroom products technology, specifically to a toilet seat hinge. Background Technology

[0002] In existing toilet structures, the toilet seat needs to be able to open and close to the toilet, and the connection method is generally a hinge, that is, the seat and the lid can be opened and closed to the toilet. In order to facilitate disassembly and cleaning, many hinges on the market use a quick-release structure. For example, patent application number 202420788536.3 discloses a magnetic hinge for toilet seats, which uses a magnetic attraction between a magnet and a metal cap for quick release. However, the metal cap of this structure is a cylindrical hollow structure, and the attraction between it and the magnet relies only on the outer ring of magnetic force, which is not very effective. After long-term use, the magnetic force will weaken, and it is easy to be pulled off the hinge when the toilet seat is opened. The magnet is fixed in the connecting post by adhesive, which is easy to fall off over time. At the same time, the metal cap and the stud are connected by threads, which is more complicated to process and more expensive. The connecting hole on the connecting seat is an open structure, and the bolt installed inside is not only unsightly but also easily corroded and rusted by urine stains or cleaning agents. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a toilet seat hinge that has a simple structure, low manufacturing cost, stronger adsorption force, long service life and beautiful appearance.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A toilet seat hinge includes a base, a support base, and a rotating bracket. The support base is inserted into the base. Two rotating brackets are provided and rotatably connected to the left and right sides of the support base, respectively. A magnetic block is fixed to the bottom end of the support base. A metal sheet is fixed to the bottom side of the base. The base has slots distributed on it. An oblong hole is distributed on the base inside the slot. A slot cover is snapped onto the slot. A locking bolt is placed in the oblong hole. When the support base is inserted into the base, the bottom plane of the magnetic block and the top plane of the metal sheet are magnetically attracted.

[0006] A further technical solution is that a guide post one extends downward from the bottom side of the support base, and a guide post two is connected to the top of the base. The magnetic block is installed and fixed on the inner side of the bottom end of the guide post one, and the metal sheet is installed and fixed on the inner side of the bottom end of the guide post two. The guide post one and the guide post two have a guiding function, so that the support base is more stable when inserted into the base.

[0007] A further technical solution is that the magnetic block is fixed to the inner side of the bottom end of the first guide post by interference fit, and the metal sheet is fixed to the inner side of the bottom end of the second guide post by riveting, interference fit, or bonding. This makes processing more convenient, eliminates the need for thread cutting, and reduces production costs.

[0008] A further technical solution is that the guide post two has insertion holes distributed inside, and a metal plate mounting groove is distributed on the bottom end of the guide post two. The metal plate mounting groove is located on the lower side of the insertion hole and is interconnected with the insertion hole. The diameter of the metal plate mounting groove is larger than the diameter of the insertion hole. The metal plate is fixed in the metal plate mounting groove on the inner side of the bottom end of the guide post two by riveting, interference fit or bonding. The diameter of the metal plate mounting groove is larger than the diameter of the insertion hole to form a stepped structure. Therefore, even if the metal plate falls off, it will be held in place and cannot move upward. It will not be pulled out when the support seat is inserted or removed, making it more reliable in use.

[0009] A further technical solution is that the base has slots distributed around the slot, the slot cover has locking buckles at both ends, and the slot cover is connected to the base near the insertion point of the support. There are four slots distributed around the slot. After two buckles are inserted into one pair of slots, the locking buckles are then inserted into the other pair of slots, and the slot cover can be snapped onto the slot.

[0010] The beneficial effects of this utility model are as follows: Compared with existing hinges on the market, this utility model provides a toilet seat hinge with a surface contact adsorption structure between the magnetic block and the metal sheet, which enhances the adsorption effect and makes the support seat less likely to detach from the base. This eliminates the need for deep processing of the metal sheet and reduces costs. Secondly, the base has a snap-on slot cover, which prevents urine stains or cleaning agents from remaining on the locking bolts, effectively avoiding rust and damage, extending service life, and improving aesthetics.

Detailed Implementation

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0020] See Figures 1 to 6 As shown, a toilet seat hinge includes a base 3, a support 2, and a rotating bracket 1. The support 2 is inserted into the base 3. Two rotating brackets 1 are provided and are rotatably connected to the left and right sides of the support 2, respectively. A magnet 7 is fixed to the bottom end of the support 2. A metal sheet 6 is fixed to the bottom side of the base 3. The base 3 has slots 9 distributed on it. On the base 3, there are waist-shaped holes 10 distributed inside the slots 9. A slot cover 4 is snapped onto the slot 9. A locking bolt 5 is placed on the waist-shaped hole 10. When the support 2 is inserted into the base 3, the bottom plane of the magnet 7 and the top plane of the metal sheet 6 are magnetically attracted.

[0021] A guide post 8 extends downwards from the bottom of the support base 2, and a guide post 11 is connected to the top of the base 3. A magnetic block 7 is fixed to the inner bottom of the guide post 8, and a metal sheet 6 is fixed to the inner bottom of the guide post 11. The guide posts 8 and 11 provide guidance, ensuring a stable fit between the support base 2 and the base 3. The magnetic block 7 is fixed to the inner bottom of the guide post 8 via an interference fit, and the metal sheet 6 is fixed to the inner bottom of the guide post 11 via riveting, interference fit, or bonding. This simplifies processing, eliminating the need for thread cutting and reducing production costs. Figure 6As shown, the guide post 2 11 has insertion holes 16 distributed inside, and a metal plate mounting groove 15 is distributed on the bottom end of the guide post 2 11. The metal plate mounting groove 15 is located on the lower side of the insertion hole 16 and is interconnected with the insertion hole 16. The diameter of the metal plate mounting groove 15 is larger than the diameter of the insertion hole 16. The metal plate 6 is fixed in the metal plate mounting groove 15 on the inner side of the bottom end of the guide post 2 11 by riveting, interference fit or bonding. The diameter of the metal plate mounting groove 15 is larger than the diameter of the insertion hole 16, forming a stepped structure. Therefore, even if the metal plate 6 falls off, it will be held in place and will not move upward. It will not be pulled out when the support seat 2 is inserted or removed, making it more reliable. The base 3 has slots 12 distributed around the slot 9. The slot cover 4 has locking buckles 14 at both ends. The slot cover 4 is connected to the support 2 and the base 3 by buckles 13. There are four slots 12 distributed around the slot 9.

[0022] In this embodiment, when the base 3 needs to be installed and fixed on the toilet, an expansion nut is provided on the toilet. The locking bolt 5 passes through the waist-shaped hole 10 distributed inside the slot 9 and is inserted into the expansion nut. The locking bolt 5 is then tightened to fix it on the toilet. Finally, the slot cover 4 is pressed into the slot 9 and snapped in place. In this way, urine stains or cleaning agents will not remain on the locking bolt 5, causing it to rust and be damaged, thus extending its service life and making it more aesthetically pleasing. Then, the support 2 is inserted into the base 3, and the bottom plane of the magnet 7 is magnetically attracted to the top plane of the metal plate 6, enabling quick disassembly and installation for easy cleaning. The two rotating brackets 1 are respectively connected to the toilet lid and the toilet seat for opening and closing. The base 3, support 2, and rotating brackets 1 are all made of metal, such as stainless steel or other metal materials. Using metal materials makes them more robust, durable, and rust-free. Metal sheet 6 is made of ferromagnetic metal, including iron, cobalt, nickel and their alloys, and can be attracted together with magnetic block 7. Its surface is treated with anti-corrosion to increase its anti-corrosion performance.
