[0036] With reference to Figures 1 to 7, this embodiment provides a toilet cover hinge seat, comprising a screw 4, a nut 3, a fixing seat 1 and a limit block 2. The fixing seat 1 is vertically arranged, the screw 4 is vertically inserted into the fixing seat 1, the nut 3 is screwed to the bottom of the screw 4, and the nut 3 is placed in the inner cavity of the fixing seat 1. The inner cavity of the fixing seat 1 forms a circumferential limit for the nut 3. The rotation of the screw 4 in the axial direction can drive the nut 3 to move vertically back and forth in the fixing seat 1. The limit block 2 is movably sleeved on the outside of the fixing seat 1 and is placed on the upper end of the nut 3, forming a top-butting fit with the nut 3. When the nut 3 slides upward with the rotation of the screw 4, it can act on the limit block 2, causing the limit block 2 to flip, and flip the originally vertically placed limit block 2 to a horizontal position. In this way, the horizontal limit block 2 is used to cooperate with the ceramic body of the toilet seat (toilet) to form a locking structure.

[0037] Specifically, vertically upwardly extending windows 11 are symmetrically provided on the left and right sides of the fixing base 1, and a flat edge 12 is protruding from the rear side of the fixing base 1. The limiting block 2 is provided with a channel 21 for the fixing base 1 to pass through, and a protrusion 22 and a groove 23 are provided on opposite sides of the channel 21. The protrusion 22 is provided at the upper edge of the channel 21, and the groove 23 is provided at the lower edge of the channel 21. When the limiting block 2 is inserted into the fixing base 1 with the channel 21, the protrusion 22 is received in the window 11 and interferes with the window edge of the window 11, limiting the movement of the protrusion 22 within the range of the window 11.

[0038] The limit block 2 is driven by the nut 3 to perform a flipping motion. In terms of the corresponding flipping arrangement, the limit block 2 includes a guide portion and a limit portion relatively arranged at both ends of its channel 21. When the screw 4 rotates to drive the nut 3 to slide downward, the limit block 2 flips for the first time under its own gravity, that is, the limit block 2 flips in its natural state until its channel 21 is substantially vertically placed, and the limit portion abuts against the plane edge 12. At this time, the limit portion forms a limiting fit with the fixing seat 1. When the screw 4 rotates to drive the nut 3 to slide upward, the nut 3 cooperates with the guide portion to enable the limit block 2 to perform a second flipping, until the nut 3 falls into the groove 23. The limit block 2 rotates until the channel 21 is substantially horizontally placed. At this time, the nut 3 cooperates with the groove 23 to form a limiting fit with the fixing seat 1.

[0039] In this embodiment, the limit block 2 includes two cards 24 symmetrically arranged on the left and right and a connecting piece 25 connecting the two cards 24. The gap between the two cards 24 forms the channel 21. The protrusion 22 is arranged on the upper edge of the card 24, and the protrusion 22 protrudes inward. A groove 23 is provided on the lower edge of the card 24; the connecting piece 25 is connected to the rear portion of the card 24. The connecting piece 25 is provided as the limit portion. Two card slots 14 are provided on the rear side of the fixing base 1. The two card slots 14 are arranged opposite to each other and are respectively arranged on the same side window edge relative to the window 11. The card slot 14 is provided at the vertical upper end of the fixing base 1.

[0040] In terms of setting, the distance between the two protrusions 22 is greater than the diameter of the screw 4, and the distance between the two protrusions 22 is smaller than the distance between the two card slots 14. When the limit block 2 is assembled on the fixing base 1, interference is formed between the protrusion 22 and the card slot 14. The force generated by the interference causes the two cards 24 to open in opposite directions, eliminating the interference between the protrusion 22 and the card slot 14, so that the protrusion 22 can pass over the card slot 14; after the interference is eliminated, the two cards 24 close in the direction of approaching each other, so that when the limit block 2 moves in the direction of separating from the fixing base 1, interference is formed again between the protrusion 22 and the card slot 14, which can prevent the limit block 2 from being easily released relative to the fixing base 1, and prevent the limit block 2 from separating from the fixing base 1.

[0041] At the same time, in the setting, the distance between the two protrusions 22 is greater than the diameter of the screw 4. No matter whether the protrusion 22 flips with the limit block 2 or the screw 4 rotates, there will be no interference between the two. In the setting, the cooperation between the window 11 and the protrusion 22 forms a limit for the limit block 2. The window 11 can be connected to the inner cavity accommodating the screw 4 or not. There is no interference between the limit block 2 and the screw 4. The flipping of the limit block 2 does not affect the rotation of the screw 4. The screw 4 can stably drive the sliding of the nut 3.

[0042] The limit block 2 does not interfere with the screw 4 when it is flipped, and the window 11 is used to expand the activity space of the protrusion 22. The limit block 2 can be flipped to vertically droop, and the limit block 2 is installed vertically on the fixed seat 1 as a whole. The limit block 2 is not tilted in the natural state, which can ensure the minimum outer diameter of the hinge seat as a whole, facilitate the assembly of the hinge seat, and facilitate the installation of the hinge seat from above the ceramic body of the toilet seat.

[0043] A planar edge 12 is provided on the rear side of the fixing base 1, extending horizontally outward. This planar edge 12 is a stepped surface, forming a planar support stop with the lower edge of the connecting piece 25 in its natural state. This planar edge 12 also serves as the rotational axis for the falling stop block 2. This planar support stop only provides a support point for rotation when the stop block 2 flips, without excessively interfering with the connecting piece 25 that rotates the stop block 2. This prevents the stop block 2 from becoming stuck when flipped due to the engagement of the stop.

[0044] The lower edge of the front part of the card 24 is a guide bevel 26, and the guide bevel 26 is the guide part; during the second flip, the nut 3 slides over the guide bevel 26 as a whole and enters the groove 23. The assembly position of the nut 3 requires a plane, or a plane with a groove, which is supported by the plane groove of the limit block 2, or the arc nut 3 cooperates with the arc groove of the limit block 2. The setting of the guide bevel 26 can make the nut 3 cooperate with the nut 3 when moving upward, forming a force pushing up on the bevel to cause the limit block 2 to flip and gradually turn to a horizontal position. The rotational assembly position of the nut 3 requires that the nut 3 and the groove 23 are limited by a plane groove or an arc groove. The purpose is that when the nut 3 is placed in the groove 23, it can form a perfect engagement with the groove 23, and the cooperation between the nut 3 and the groove 23 is used to limit the limit block 2 from moving back and forth or swinging up and down in a horizontal state, so as to maintain a good levelness. When the nut 3 slides and falls into the groove 23, the groove 23 can provide the nut 3 with a more stable method of pushing the limiting block 2 to continue to move upward until it moves to the limit position.

[0045] Preferably, the limit block 2 is an integral part, which can be a stamping part or an injection molded part.

[0046] In this embodiment, the fixing base 1 is symmetrically provided with vertically extending ribs 13 on the front and rear sides. These ribs 13 are positioned within the inner cavity of the fixing base 1. The nut 3 is provided with a limiting groove 31 corresponding to the rib 13. The nut 3 moves along a predetermined length of the rib 13 by cooperating with the limiting groove 31 and the rib 13. When the screw 4 rotates and drives the nut 3 to reciprocate vertically, the rib 13 not only limits the left-right and forward-backward movement of the nut 3, ensuring that the nut 3 moves only vertically, but also limits unstable shaking caused by the rotation of the screw 4. Similarly, the nut 3 is restrained within the inner cavity of the fixing base 1 by the rib 13 and further limited left and right by the window 11, ensuring that the nut 3 can only move up and down. This prevents the fixing base 1 from swinging in the vertical position, thereby maintaining good verticality. When the nut 3 is set, it is sufficient that the upper end surface of the nut 3 can abut against the lower edge of the card 24.

[0047] In this embodiment, the fixing base 1 includes an upper base 15, a lower base 16, a front column 17 and a rear column 18 connected between the upper base 15 and the lower base 16. The upper base 15 is provided with a through hole for the screw 4 to pass through. The flat edge 12 is provided on the rear column 18. Two ribs 13 are provided on the inner sides of the front column 17 and the rear column 18. The slot 14 is provided on both sides of the front column 17. The gap between the left edge and the right edge of the front column 17 and the rear column 18 respectively constitute the window 11. Directly utilizing the provision of the window 11 to form a limit for the limit block 2 can simplify the overall structure of the fixing base 1. The limit block 2 can be placed vertically on the outside of the fixing base 1, reducing the overall outer diameter and making assembly easier.

[0048] Preferably, the fixing base 1 is an integral injection molded part. The fixing base 1 is provided with a through hole for the screw 4 to pass through on the upper top base 15, and the lower top base 16 is provided with a limiting hole for inserting the screw 4 corresponding to the through hole of the upper top base 15, which can also be a clearance hole. That is, when the screw 4 is tightened, the lower part of the screw 4 can be inserted into the limiting hole or pass through the clearance hole, so that the height of the fixing frame can be relatively small.

[0049] This embodiment provides a toilet cover hinge seat. When in use, in a natural state (as shown in FIG5 ), the stopper 2 naturally droops to a position perpendicular to the outer side of the fixing seat 1, with the lower edge of the connecting piece 25 abutting against the flat edge 12 to form a planar support. The fixing seat 1 is vertically disposed as a whole, with the guide bevel 26 located directly above the nut 3. To tighten, the screw 4 is rotated to lift the nut 3 and slide it upward. After contacting the guide bevel 26, it gradually pushes upward along the guide bevel 26 to lift the front end of the stopper 2 (as shown in FIG6 ). After the nut 3 has completely slid past the guide bevel 26, the stopper 2 is rotated until it is substantially horizontal. Simultaneously, the nut 3 slides into the groove 23 of the stopper 2. The nut 3 and the groove 23 form a limit to restrict the forward and backward movement of the stopper 2. The screw 4 is then rotated further to lift the nut 3. Finally, the upper edge end face of the stopper 2 on the fixing seat 1 cooperates with the ceramic body of the toilet seat to achieve locking and fixation (as shown in FIG7 ). When unlocking is required, the screw 4 is loosened to lower the nut 3. Initially, the limit block 2 moves downward horizontally until the plane edge 12 blocks the connecting piece 25. After the nut 3 continues to descend, the front end of the limit block 2 swings downward, and finally the nut 3 drops to the bottom and returns to its initial natural state.

[0050] The above is only a preferred specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with this technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention. Industrial Applicability

[0051] The present invention provides a hinge seat for a toilet cover. By arranging ribs on the fixing seat to cooperate with the limiting grooves provided on the nut, the nut will not move left and right when it moves vertically back and forth in the fixing seat, and the nut will not shake or become unstable, will not interfere with the rotation of the limiting block, and will not be stuck, so that the limiting block can be flipped and raised to the extreme position. The plane edge and the connecting piece are set as plane support limits, so that the limiting block can be flipped to vertically droop, ensuring the overall minimum outer diameter of the product and facilitating the installation of the product. The protrusions are set to interfere with the card slots, and the spacing between the protrusions on both sides is greater than the diameter of the screw. The movable range of the protrusions is limited to the window of the fixing seat. When the limiting block is flipped, there is no interference between the protrusions and the screw, which facilitates the limiting block to be well flipped. It has good industrial applicability.
