For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] refer to Figures 1-12 This embodiment provides an integrated quick locking device, which is mainly used for installation between the ceramic body 1 of a toilet seat (toilet) and the toilet cover. The locking device is a toilet cover hinge seat.

[0045] like Figure 1 The locking device includes a main body 1, a screw 2, a rotating body 3 and a nut 4. The main body 1 is arranged vertically. The screw 2 is passed through the main body 1 and is spirally connected to the nut 4. Rotating the screw 2 can realize the vertical up and down reciprocating movement of the nut 4. The rotating body 3 is rotatably assembled on the main body 1 and is located above the nut 4. The nut 4 moves upward to drive the rotating body 3 to rotate, so that it is stuck in the ceramic hole 5 of the ceramic body 1 to complete the installation of the toilet cover.

[0046] Specifically, such as Figure 4-5 The main body 1 defines a housing chamber 11 with openings 12 at the top and bottom thereof communicating with the outside. A guide groove 13 is defined on the sidewall of the housing chamber 11 for connection to the outside. The screw 2 passes through the opening 12 from top to bottom and is inserted into the housing chamber 11. The nut 4 is screwed to the screw 2 and slidably placed within the housing chamber 11. The rotating body 3 is rotationally connected to the guide groove 13.

[0047] In the free state, the rotating body 3 is placed approximately vertically, and the vertex 31 of the rotating body 3 is located to the right of the axis of the screw 2. When the rotating body 3 rotates, the vertex 31 can quickly rotate to the right through the installation area of the ceramic hole 5 to achieve quick installation.

[0048] like Figure 2-3 The rotating body 3 includes two symmetrically arranged cards 32 and a connecting piece 33 connecting the two cards 32. The connecting piece 33 is set at the top of the card 32, and the upper edge of the connecting piece 33 is set as a bevel 34. When the locking device is disassembled, it needs to be pulled out from the ceramic hole 5. The bevel 34 on the upper side of the connecting piece 33 guides through the ceramic hole 5, which can quickly and smoothly achieve disassembly and detach from the ceramic hole 5.

[0049] The bottom of the card 32 is provided with a first curved surface 35, which is arranged in an upward arc shape toward the position of the vertex 31. The first curved surface 35 cooperates with the nut 4. When the nut 4 moves upward, it acts on the first curved surface 35, causing the first curved surface 35 to slide relative to the nut 4, causing the bottom of the card 32 to rotate to the left and the vertex 31 of the rotating body 3 to rotate to the clockwise.

[0050] A second arc surface 36 is provided on one side of the card 32, and a first plane 37 is provided on the other side. When the rotating body 3 rotates, the second arc surface 36 rotates upward and the first plane 37 rotates downward. As the nut 4 moves upward, the rotating body 3 gradually rotates to a position where it is roughly horizontal. The second arc surface 36 abuts against the bottom of the ceramic hole 5 and makes point contact with the ceramic hole 5. The first plane 37 abuts against the top surface of the nut 4. At this time, the locking device is in a locked state.

[0051] The two clips 32 are symmetrically arranged, and protrusions 30 are provided on the inner sides of the two clips 32 facing each other. The protrusions 30 are symmetrically arranged on the two clips 32. The rotating body 3 is fixed in the guide groove 13 by the protrusions 30. The protrusions 30 serve as a mounting limiter to prevent the rotating body 3 from separating from the main body 1 during movement. The spacing between the two protrusions 30 is greater than the diameter of the screw 2, which can avoid interference with the movement of the screw 2. The range of movement of the two protrusions 30 is limited within the guide groove 13, providing smooth rotation of the rotating body 3.

[0052] like Figure 5-7 A guide rib 17 is provided on the side wall of the accommodating cavity 11, and a guide rib 17 is provided on the side wall on both sides of the guide groove 13. Two guide grooves 41 are provided on the side of the nut 4 corresponding to the position of the guide rib 17. The guide groove 41 cooperates with the guide rib 17 to play a guiding role. The nut 4 reciprocates along the predetermined length of the guide rib 17, which can ensure the stability of the vertical upward and downward movement of the nut 4.

[0053] The bottom surface of the nut 4 is flat and is placed at the bottom of the accommodating cavity 11. The top surface of the nut 4 is provided with a third flat surface 42 and a fourth flat surface 43. The third flat surface 42 is lower than the fourth flat surface 43. The first curved surface 35 and the third flat surface 42 form a support. The fourth flat surface 43 is provided with a threaded hole, forming a step between the third flat surface 42 and the fourth flat surface 43. When the first curved surface 35 and the third flat surface 42 are in sliding engagement, the step acts as a guide, ensuring a better and more stable sliding engagement between the third flat surface 42 and the first curved surface 35.

[0054] The rotating body 3 and the main body 1 rotate together by forming a stepped surface 14 protruding outward from the side wall of the main body 1. The stepped surface 14 is connected to the guide groove 13 and is used to cooperate with the connecting piece 33. When the rotating body 3 is in a free state, the lower edge of the connecting piece 33 rests on the stepped surface 14, providing support.

[0055] A third curved surface 38 is provided at the connection point between the lower edge of the connecting piece 33 and the card 32. The connection point between the stepped surface 14 and the guide groove 13 is the axis point 15. A second flat surface 39 is provided where the card 32 connects to the third curved surface 38. The first flat surface 37 is connected to the second flat surface 39. When the rotating body 3 is in a free state, the second flat surface 39 contacts the side plane 18 of the guide groove 13. When the rotating body 3 rotates, the second flat surface 39 and the axis point 15 form a rotation support point, allowing the second flat surface 39 to rotate around the axis point 15. The provision of the third curved surface 38 can make the rotation of the rotating body 3 smoother, and the third curved surface 38 and the axis point 15 form an arc-shaped support, which can reduce wear on the device during rotation.

[0056] A conical platform 16 is provided at the upper end of the body 1. When the locking mechanism is locked, the platform 16 engages securely within the ceramic hole 5. When disassembly is required, the platform 16 provides an accessible position for upward extraction of the locking mechanism. The end of the screw 2 is screwed onto the platform 16. The rotating body 3 is in a free state, supporting the platform 16. The beveled edge 34 of the connecting piece 33 guides the connecting piece through the ceramic hole 5.

[0057] The specific operation of the locking device is as follows:

[0058] The rotating body 3 cooperates with the nut 4 to have a first position and a second position. The first position is an initial position, and the rotating body 3 is in a free state. The second position is a locked position.

[0059] Initial state, such as Figure 8 The rotating body 3 is located in the first position, the nut 4 is sunk to the bottom of the accommodating cavity 11, the screw 2 is connected to the main body 1 through the nut 4, and when the rotating body 3 is in a free state, the first arc surface 35 is supported by the nut 4, the lower edge of the connecting piece 33 is supported by the step surface 14, and the third arc surface 38 is supported by the axis point 15. The rotating body 3 is placed roughly vertically.

[0060] Rotation state, such as Figure 9-10 , it changes from the first position to the second position, rotates the screw 2 to lift the nut 4, the nut 4 contacts the first arc surface 35 and gradually lifts the rotating body 3, the connecting piece 33 moves to the right, and the second plane 39 moves to the right to contact the axis point 15; as the nut 4 rises, the nut 4 slides over the first arc surface 35 to drive the rotating body 3 to start rotating, and the second plane 39 rotates around the axis point 15; the nut 4 continues to rise until the first plane 37 of the rotating body 3 contacts the third plane 42 of the nut 4, and the second arc surface 36 of the rotating body 3 contacts the ceramic hole 5.

[0061] Locked state, such as Figure 11The rotating body 3 is located in the second position, the first plane 37 is supported by the nut 4, the rotating body 3 is rotated to be placed substantially horizontally, the second arc surface 36 is in point contact with the ceramic hole 5, and the locking device tightens the ceramic hole 5.

[0062] Disassembled state, such as Figure 12 The rotating body 3 changes from the second position to the first position, and the screw 2 is rotated to lower the nut 4 to the bottom of the accommodating chamber 11. The rotating body 3 returns to a free state, lifts the conical platform 16 of the main body 1, and the oblique edge 34 on the connecting piece 33 is guided through the ceramic hole 5 until the entire device passes through the ceramic hole 5, completing the disassembly.

[0063] 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 the 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.
