Description

Technical Field

[0001] This utility model relates to fixing devices; in particular, it refers to a single-screw quick-installation nut. Background Technology

[0002] Please refer to the existing structure where the faucet is fixed with a nut. Figure 19 As shown, when the faucet 50 is installed on a washbasin or sink, a screw 52 is connected to the faucet 50. After the screw 52 passes downward through the washbasin or sink, a base plate 54 is placed against the bottom side of the washbasin or sink and fitted around the screw 52. Then, a nut 56 is screwed onto the screw 52. The nut 56 abuts against the base plate 54, so that the base plate 54 can be supported on the bottom side of the washbasin or sink, thereby fixing the faucet 50 to the washbasin or sink.

[0003] The existing structure, which uses a nut to screw onto a base plate, can secure a faucet to a basin or sink. However, the space under basins or sinks is generally quite small, and a wrench typically used to turn the nut requires ample space around it for easy operation. Therefore, this structure, where the faucet is secured to the base plate by the nut, is cumbersome for the user and requires further improvement. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a nut structure that can be quickly installed on a screw. It can be operated with straight rod-shaped tools such as L-shaped wrenches, making it convenient for users to fix this utility model on a screw in narrow operating spaces. The faucet or water tank is fixed to the other end of the screw by the utility model being supported against or against objects such as washbasins, sinks, or water tank seats.

[0005] To achieve the above objectives, this utility model provides a single-screw quick-install nut, comprising a housing, a threaded component, and a pressing component. The housing has a retaining ring and a shaft hole; the shaft hole extends along a central axis, and a first pressing portion is formed on the inner peripheral wall of the shaft hole; the retaining ring and the first pressing portion are arranged at intervals along the central axis.

[0006] The screw assembly includes a first pipe segment, a second pipe segment, and a third pipe segment that are coaxial and sequentially connected along the central axis; the outer diameter of the first pipe segment is smaller than the outer diameter of the second pipe segment; a hook is connected to the end edge of the first pipe segment away from the second pipe segment, the first pipe segment passes through the shaft hole and the hook is hooked onto the side of the buckle away from the first pressing part; a lateral channel is formed through one side of the first pipe segment and the second pipe segment, a pair of recesses are formed on the circumferential sides of the lateral channel on the outer peripheral wall of the second pipe segment, and a portion of the threads are formed on the inner peripheral wall of the first pipe segment and the second pipe segment where the lateral channel is not formed; a driving hole is formed in the third pipe segment, and the driving hole is a non-circular hole.

[0007] The pressing component has a body that is radially slidable along the central axis and embedded in the lateral channel. A pressing portion is formed on the side of the body facing the partial thread. The other side of the body away from the partial thread protrudes from the lateral channel and forms a second pressing portion. The second pressing portion abuts against the first pressing portion and can slide along the first pressing portion in a direction inclined to the central axis. A pair of radial springs are formed on both sides of the circumference of the body. Each pair of radial springs is elastic and abuts against each pair of recesses.

[0008] In use, this invention involves fitting the single-screw quick-install nut onto a screw connecting to an object. The screw passes through the object's mounting point, and the single-screw quick-install nut is threaded onto the screw via the threaded portion of the engagement piece. The engagement piece can be rotated directly or by inserting an L-shaped wrench into the drive hole; simultaneously, the housing abuts against the object's mounting point, and the engagement piece moves closer to the housing.

[0009] When the housing and the screw fastener are close to each other, the second pressing part of the pressing member is pressed by the first pressing part of the housing, causing the second pressing part to slide along the first pressing part in a direction inclined to the central axis. This drives the body of the pressing member to move into the lateral channel. The pressing part of the pressing member, in conjunction with the thread of the screw fastener, presses the screw, fixing the present invention to the screw. The housing abuts against the object's mounting location, providing the effect of fixing the object to the mounting location.

[0010] The advantage of this invention is that the single-screw quick-install nut can be operated with a straight-bar tool such as an L-shaped wrench, making it convenient for users to fix the single-screw quick-install nut on the screw in narrow spaces so that it can be supported against the water tank seat of objects such as washbasins, sinks, or toilets. This allows the faucet or water tank connected to the other end of the screw to be fixed to the water tank seat of the washbasin, sink, or toilet. Attached Figure Description

[0108] To more clearly illustrate this utility model, preferred embodiments are described in detail below with reference to the accompanying drawings. Please refer to... Figures 1 to 6 As shown, this is a single-screw quick-install nut 100 according to a first preferred embodiment of the present invention. The single-screw quick-install nut 100 has a central shaft L and includes a housing 10, a threaded component 20, and a pressing component 30. In the following description of the single-screw quick-install nut 100, the up and down directions are defined with respect to opposite sides of the central shaft L, wherein:

[0109] The housing 10 is centered on the central axis L and has a retaining ring 11 and a shaft hole 12. In this preferred embodiment, the housing 10 includes a gasket 14, a cap 16, and a plurality of axial springs 18. The gasket 14 is an X-shaped plate with the retaining ring 11 formed in the middle. The middle of the gasket 14 abuts against the upper end of the cap 16. The shaft hole 12 is formed on the inner side of the cap 16, and a first pressing portion 13 is formed on the side of the shaft hole 12 opposite to the gasket 14. In this preferred embodiment, the first pressing portion 13 is an annular conical surface, and the inner diameter of the first pressing portion 13 on the side near the gasket 14 is smaller than the inner diameter of the other side of the first pressing portion 13 opposite to the gasket 14. In general, the retaining ring 11 and the first pressing portion 13 are arranged vertically at intervals along the central axis L. The axial springs 18 are connected to the lower edge of the cap 16 away from the gasket 14. The axial springs 18 are parallel to the central axis L and arranged in a circle. The axial springs 18 are elastic sheets and each has a free end 181.

[0110] The threaded assembly 20 is a straight tube centered on the central axis L. The threaded assembly 20 includes a first tube segment 22, a second tube segment 24, and a third tube segment 26, which are coaxially connected vertically along the central axis L. The outer diameter of the first tube segment 22 is smaller than the outer diameter of the second tube segment 24, and the outer diameter of the second tube segment 24 is smaller than the outer diameter of the third tube segment 26. A hook 28 is connected to the end edge of the first tube segment 22 opposite to the second tube segment 24. The first tube segment 22 passes through the shaft hole 12 of the housing 10, and the hook 28 is engaged with the side of the retaining ring 11 opposite to the first pressing part 13, that is, the hook 28 is engaged with the upper side of the retaining ring 11.

[0111] A lateral channel 21 is formed on one side around the first pipe segment 22 and the second pipe segment 24. The lateral channel 21 is a long rectangular hole and penetrates radially along the central axis L through one side of the first pipe segment 22 and the second pipe segment 24, so that the lateral channel 21 communicates with the interior of the first pipe segment 22 and the second pipe segment 24. A pair of recesses 23 are formed on the outer peripheral wall of the second pipe segment 24 corresponding to the circumferential sides of the lateral channel 21. A portion of the inner peripheral wall of the first pipe segment 22 and the second pipe segment 24 without the lateral channel 21 is formed with threads 25. A portion of the outer peripheral wall of the second pipe segment 24 adjacent to the first pipe segment 22 is formed with an inclined surface 27. The inclined surface 27 is an arc-shaped conical surface and is spaced apart from the first pressing part 13 of the sleeve 10.

[0112] The third tube segment 26 extends out of the shaft hole 12 of the housing 10. The outer peripheral wall of the third tube segment 26 adjacent to the second tube segment 24 forms a support surface 261. The support surface 261 is an annular conical surface, and the outer diameter of the support surface 261 on the side closer to the second tube segment 24 is smaller than the outer diameter on the other side of the support surface 261 away from the second tube segment 24. The cap 16 is used to connect the end edges of the axial springs 18. In addition to being described above as being away from the end edge of the gasket 14, the cap 16 can also be described as being close to the end edge of the support surface 261. The axial springs 18 connected to the cap 16 abut against the support surface 261 with their free ends 181. Therefore, when the housing 10 and the threaded engagement 20 are driven to approach each other by an external force, the support surface 261 will push the axial springs 18 to bend along the central axis L. This allows the restoring force of the axial springs 18 to push the housing 10 away from the threaded engagement 20 after the external force that caused the housing 10 and the threaded engagement 20 to approach each other disappears, so that the housing 10 and the threaded engagement 20 return to their original positions.

[0113] A driving hole 262 is formed within the third pipe section 26. The driving hole 262 is hexagonal and leads to the space surrounded by the thread 25. In other preferred embodiments, the driving hole 262 may also be a square hole or other polygonal hole, or a star-shaped hole or other non-circular hole, so that a corresponding wrench can be inserted to rotate the threaded engagement 20. A plurality of anti-slip grooves 263 are formed on the outer peripheral wall of the third pipe section 26. These anti-slip grooves 263 are arranged around the central axis L. These anti-slip grooves 263 can provide friction for the user when gripping the third pipe section 26, allowing the user to more easily rotate the threaded engagement 20 by rotating the third pipe section 26.

[0114] The pressing member 30 has a body 32, which is a block shaped to conform to the lateral channel 21. The body 32 is embedded in the lateral channel 21 in a manner that allows it to slide radially along the central axis L. A pressing portion 321 is formed on the side of the body 32 facing the partial thread 25. In this preferred embodiment, the pressing portion 321 is a partial thread that can form a complete thread with the partial thread 25 of the threaded member 20. In other preferred embodiments, the pressing portion 321 may also be a portion of the pipe wall.

[0115] The pressing part 321 is generally aligned with the inner peripheral wall of the second pipe segment 24; in other preferred embodiments, the pressing part 321 may also be slightly recessed within the inner peripheral wall of the second pipe segment 24, that is, the pressing part 321 may be located within the lateral channel 21. The body 32, on the side opposite to the partial thread 25, that is, the outer side of the body 32 protrudes from the lateral channel 21, and a second pressing part 34 is formed on the outer side of the body 32 facing the first pressing part 13. The second pressing part 34 abuts against the first pressing part 13, and there may be a gap between them. The gap between the partial inclined surface 27 and the first pressing part 13 is greater than the gap between the second pressing part 34 and the first pressing part 13. In this preferred embodiment, the second pressing part 34 is an arc-shaped conical surface and abuts against the first pressing part 13. Therefore, when the housing 10 and the screw 20 approach each other, and the pressing member 30 also approaches the housing 10 along with the screw 20, the second pressing part 34 can slide along the first pressing part 13 in a direction inclined to the central axis L.

[0116] A pair of radial spring pieces 36 are formed on both sides of the circumference of the main body 32. Each pair of radial spring pieces 36 is elastic and abuts against each pair of recesses 23 of the threaded member 20. Therefore, when the housing 10 and the threaded member 20 are driven closer to each other by an external force, causing the pressing member 30 to also move closer to the housing 10, the second pressing portion 34 of the pressing member 30 will be pressed by the first pressing portion 13. This causes the main body 32 to move radially inward into the threaded member 20 along the central axis L, and the pressing portion 321 to move to a position protruding inward from the inner circumferential wall of the second pipe section 24, allowing the pressing portion 321 to engage with the threaded member 20. The thread 25 presses against the screw threaded into the engagement member 20; at the same time, each pair of recesses 23 pushes the pair of radial springs 36 to bend, so that when the housing 10 and the engagement member 20 return to their original positions and the second pressing part 34 is no longer pressed by the first pressing part 13, the restoring force of the radial springs 36 can push the body 32 of the pressing member 30 back to its original position, and at this time the pressing part 321 no longer presses against the screw thread.

[0117] When using the first preferred embodiment described above, please refer to... Figure 1 , Figure 2 and Figures 6 to 8As shown, the housing 10 is used with the screw thread 20 facing downwards. When a faucet 50 is fixed using the single-screw quick-install nut 100, the faucet 50 is mounted on a washbasin or sink. A screw 52 is connected to the faucet 50, and the screw 52 passes downwards through the washbasin or sink. The single-screw quick-install nut 100 is fitted onto the screw 52, ​​which passes through the housing 10 and is loosely screwed into the thread 25 of the screw thread. The washer 14 of the housing 10 is slightly abutted against the bottom side of the washbasin or sink.

[0118] Next, the screw engagement 20 is rotated by inserting an L-shaped wrench into the drive hole 262, or by the user directly rotating the third pipe section 26 by hand. This causes the housing 10 to abut against the bottom of the basin or sink through which the screw 52 passes. Because the screw engagement 20 is screwed into the screw 52, ​​it also moves closer to the housing 10 as it is rotated, pushing the housing 10 towards the bottom of the basin or sink. As the threaded part 20 approaches the housing 10, the second pressing part 34 of the pressing part 30 is pressed by the first pressing part 13 of the housing 10, causing the second pressing part 34 to slide along the first pressing part 13 in a direction inclined to the central axis L. This drives the body 32 of the pressing part 30 to move relatively into the lateral channel 21. Finally, the pressing part 321 cooperates with the thread 25 of the threaded part 20 to press the screw 52, ​​fixing the single screw quick-install nut 100 to the screw 52. At the same time, the washer 14 of the housing 10 tightly abuts against the bottom side of the basin or sink to provide support, fixing the faucet 50 to the basin or sink.

[0119] When the single-screw quick-install nut 100 needs to be removed from the screw 52, ​​simply rotate the threaded engagement 20 in the opposite direction. Combined with the restoring force of the axial springs 18 against the support surface 261, the threaded engagement 20 can move relatively away from the housing 10. At this time, the first pressing part 13 of the housing 10 no longer presses against the second pressing part 34 of the pressing member 30, causing the pressing part 321 to release the screw 52. The single-screw quick-install nut 100 can then be pulled out of the screw 52. During the process of pulling out the single-screw quick-install nut 100 from the screw 52, ​​the restoring force of the radial springs 36 on both sides of the pressing member 30 moves the body 32 out of the lateral channel 21, preventing the pressing part 321 from obstructing the movement of the screw 52 within the threaded engagement 20. The advantage of this utility model is that, during the process of fixing this utility model to the screw 52, ​​the screw assembly 20 can be rotated by an L-shaped wrench or directly by hand for installation, which makes it convenient for users to operate in narrow spaces, and can quickly fix the single screw quick-install nut 100 to the screw 52, ​​making it convenient for users to use.

[0120] In addition to the first preferred embodiment described above, in which the housing 10 is configured as two separable elements including the gasket 14 and the cap 16, in other preferred embodiments of the present invention, the housing 10 may also be configured as an integral structure, as in the second preferred embodiment of the present invention described below.

[0121] Please refer to Figures 9 to 11 As shown, the single-screw quick-install nut 100A of the second preferred embodiment of this utility model, like the single-screw quick-install nut of the first preferred embodiment, includes a housing 10A, a threaded component 20A, and a pressing component 30A. The housing 10A is centered on a central shaft L and has a shaft hole 12A. The housing 10A includes a straight tube 14A, a cap 16A, and a plurality of axial spring tabs 18A. The straight tube 14A is the tube body and is concentric with the cap 16A. The straight tube 14A is integrally connected to the end of the cap 16A opposite to the axial spring tabs 18A, that is, the straight tube 14A is connected to the upper end of the cap 16A.

[0122] The buckle 11A is formed on the inner peripheral wall of the straight tube 14A. The shaft hole 12A is formed on the inner side of the cap 16A, and a first pressing part 13A is formed on the side of the shaft hole 12A opposite to the straight tube 14A. The first pressing part 13A is an annular conical surface. Axial spring pieces 18A are connected to the end edge of the cap 16A opposite to the straight tube 14A. The axial spring pieces 18A are elastic plates parallel to the central axis L and arranged in a circular pattern.

[0123] The specific structure of the threaded engagement member 20A and the pressing member 30A in the second preferred embodiment of the present invention, the connection relationship between the threaded engagement member 20A, the pressing member 30A and the housing member 10A, and the function that the single screw quick-install nut 100A formed by the combination of the threaded engagement member 20A, the pressing member 30A and the housing member 10A can perform are all the same as the structure of the housing member, the threaded engagement member and the pressing member in the first preferred embodiment.

[0124] In addition to the first preferred embodiment described above, in which the first pressing part 13 of the housing 10 is set as an annular conical surface, in other preferred embodiments of the present invention, the first pressing part 13 may also be set as other shapes that allow the second pressing part 34 of the pressing member 30 to abut against it and slide along the direction inclined to the central axis L, as described below in the third preferred embodiment of the present invention.

[0125] Please refer to Figures 12 to 13 As shown, the single-screw quick-install nut 100B of the third preferred embodiment of this utility model also includes a housing 10B, a threaded component 20B, and a pressing component 30B. The housing 10B also includes a washer 14B, a cap 16B, and a plurality of axial springs 18B, wherein the washer 14B abuts against the upper end of the cap 16B, and the axial springs 18B are connected to the lower edge of the washer 14B. The inner side of the cap 16B of the housing 10B has a first pressing portion 13B, which includes a plurality of circular edges 131B arranged at intervals along the central axis L. The circular edges 131B are concentric, and the diameter of the circular edges further away from the washer 14B (and its retaining ring) is larger. The circular edges 131B are used to abut against the second pressing portion 34B of the pressing component 30B.

[0126] The remaining structure of the gasket 14B in the third preferred embodiment of the present invention, the specific construction of the threaded member 20B and the pressing member 30B, the connection relationship between the threaded member 20B, the pressing member 30B and the housing member 10B, and the function that the single screw quick-install nut 100B formed by the combination of the pressing member 30B and the housing member 10B can perform are all the same as the structure of the housing member, the threaded member and the pressing member in the first preferred embodiment.

[0127] In addition to the first to third preferred embodiments described above, in which the housing faces upward and the screw-on component faces downward, the fourth preferred embodiment of this utility model, as described below, can also be used with the orientation reversed. Please refer to... Figures 14 to 17 As shown, the single-screw quick-install nut 100C of the fourth preferred embodiment of this utility model has a central shaft L and includes a housing 10C, a screw engagement member 20C, and a pressing member 30C, wherein:

[0128] The housing 10C is centered on the central axis L and has a shaft hole 12C. A retaining ring 11C, a plurality of sliders 15C, and a first pressing part 13C are formed along the central axis L on the inner peripheral wall of the shaft hole 12C. The retaining ring 11C and the first pressing part 13C are arranged at intervals along the central axis L. The sliders 15C are strip-shaped blocks along the central axis L and are located between the retaining ring 11C and the first pressing part 13C. The sliders 15C are arranged at intervals around the central axis L, and one end of each slider 15C is connected to the side of the retaining ring 11C facing the first pressing part 13C. The first pressing part 13C is an annular conical surface, and the inner diameter of the first pressing part 13C on the side closer to the retaining ring 11C is smaller than the inner diameter of the other side of the first pressing part 13C away from the retaining ring 11C. A pair of levers 17C are formed on both sides of the outer peripheral wall of the housing 10C.

[0129] The threaded fitting 20C is a straight tube centered on the central axis L. The threaded fitting 20C includes a first tube segment 22C, a second tube segment 24C, and a third tube segment 26C, which are coaxially connected vertically along the central axis L. The outer diameter of the first tube segment 22C is smaller than the outer diameter of the second tube segment 24C, and the outer diameter of the second tube segment 24C is smaller than the outer diameter of the third tube segment 26C. A hook 28C is connected to the end edge of the first tube segment 22C opposite to the second tube segment 24C. The first tube segment 22C passes through the shaft hole 12C of the housing 10C, and the hook 28C is engaged with the side of the retaining ring 11C opposite to the first pressing part 13C. A plurality of tracks 29C are formed in a circumferential arrangement at the end edge of the first pipe segment 22C away from the second pipe segment 24C. These tracks 29C are long grooves extending along the central axis and respectively accommodate each slider 15C, so that each slider 15C can slide along the central axis L on the track 29C. In this way, the threaded engagement 20C can move forward and backward along the central axis L towards a direction deeper into the shaft hole 12C. And by accommodating the sliders 15C through the tracks 29C, when the housing 10C rotates around the central axis L, it will drive the threaded engagement 20C to rotate together.

[0130] A lateral channel 21C is formed on one side of the first pipe segment 22C and the second pipe segment 24C. The lateral channel 21C is a long rectangular hole and penetrates radially along the central axis L through one side of the first pipe segment 22C and the second pipe segment 24C, so that the lateral channel 21C communicates with the interior of the first pipe segment 22C and the second pipe segment 24C. A pair of recesses 23C are formed on the outer peripheral wall of the second pipe segment 24C corresponding to the circumferential sides of the lateral channel 21C. A portion of the inner peripheral wall of the first pipe segment 22C and the second pipe segment 24C without the lateral channel 21C is formed with threads 25C. A portion of the outer peripheral wall of the second pipe segment 24C adjacent to the first pipe segment 22C is formed with an inclined surface 27C. The inclined surface 27C is an arc-shaped conical surface and is spaced apart from the first pressing part 13C of the sleeve 10C. The third tube segment 26C extends at least partially beyond the shaft hole 12C of the housing 10C, and a through hole 264C is formed inside the third tube segment 26C, which leads to the space surrounded by the partial thread 25C.

[0131] The pressing component 30C has a body 32C, which is a block shaped to conform to the lateral channel 21C. The body 32C is embedded in the lateral channel 21C in a manner that allows it to slide radially along the central axis L. A pressing portion 321C is formed on the side of the body 32C facing the partial thread 25C. In this preferred embodiment, the pressing portion 321C is a partial thread that can form a complete thread with the partial thread 25C of the threaded component 20C. In other preferred embodiments, the pressing portion 321C may also be a portion of the pipe wall.

[0132] The pressing part 321C is generally aligned with the inner peripheral wall of the second pipe segment 24C; in other preferred embodiments, the pressing part 321C may also be slightly recessed within the inner peripheral wall of the second pipe segment 24C, that is, the pressing part 321C may be located within the lateral channel 21C. The body 32C, on the other side away from the partial thread 25C, that is, the outer side of the body 32C protrudes from the lateral channel 21C, and a second pressing part 34C is formed on the outer side of the body 32C facing the first pressing part 13C. The second pressing part 34C abuts against the first pressing part 13C, and there may be a gap between the two. In this preferred embodiment, the second pressing part 34C is an arc-shaped conical surface and abuts against the first pressing part 13C. Therefore, when the housing 10C and the screw 20C approach each other, and the pressing part 30C also approaches the housing 10C along with the screw 20C, the second pressing part 34C can slide along the first pressing part 13C in a direction inclined to the central axis L.

[0133] A pair of radial spring tabs 36C are formed on both sides of the circumferential direction of the main body 32C. Each pair of radial spring tabs 36C is elastic and abuts against each pair of recesses 23C of the threaded member 20C. Therefore, when the housing member 10C and the threaded member 20C are driven closer to each other by an external force, and the pressing member 30C also moves closer to the housing member 10C along with the threaded member 20C, the second pressing part 34C of the pressing member 30C is pressed by the first pressing part 13C, causing the main body 32C to move radially inward into the threaded member 20C along the central axis L, and causing the pressing part 321C to move to a position protruding inward from the inner circumferential wall of the second tube section 24C, so that the pressing part 321C can cooperate. The thread 25C presses against the screw threaded into the engagement member 20C; at the same time, each pair of recesses 23C pushes the pair of radial springs 36C to bend, so that when the housing 10C and the engagement member 20C return to their original positions and the second pressing part 34C is no longer pressed by the first pressing part 13C, the restoring force of the radial springs 36C can push the body 32C of the pressing member 30C back to its original position, and at this time the pressing part 321C no longer presses against the aforementioned screw.

[0134] When using the single-screw quick-install nut 100C of the fourth preferred embodiment of this utility model, please refer to... Figure 15 , Figure 17 and Figure 18 As shown, the screw assembly 20C is used with its direction upward and the housing 10C's direction downward. When a water tank 60 is fixed using the single-screw quick-install nut 100C, the water tank 60 is mounted on a toilet tank seat 64, and a screw 62 is connected to the water tank 60, passing downward through the toilet tank seat 64. In use, the single-screw quick-install nut 100C is fitted onto the screw 62, which passes through the housing 10C and is loosely screwed into the thread 25C of the screw assembly 20C. At the same time, the third pipe section 26 of the screw assembly 20C slightly abuts against the bottom side of the toilet tank seat 64.

[0135] Next, the user rotates the housing 10C by hand, causing the threaded part 20C to rotate as well. While rotating the housing 10C, the user's hand should also apply force to move the housing 10C toward the threaded part 20C. This causes the first pressing part 13C of the housing 10C to press the second pressing part 34C of the pressing part 30C, causing the second pressing part 34C to slide along the first pressing part 13C in a direction inclined to the central axis L. This drives the body 32C of the pressing part 30C to move into the lateral channel 21C, so that the pressing part 321C and the partial thread 25C form a complete thread, which is screwed around the screw 62.

[0136] When the user rotates the housing 10C and the threaded engagement 20C together by hand, the pressing part 321C and the threaded part 25C are pushed upward relative to the threaded engagement 20C, so that the threaded part 321C and the threaded part 25C form a complete thread and are screwed around the screw 62. Therefore, the rotation of the housing 10C and the threaded engagement 20C will eventually cause the third pipe section 26C of the threaded engagement 20C to move towards the toilet tank seat 64 and tightly abut against the bottom side of the toilet tank seat 64. This allows the single screw quick-install nut 100C to be locked to the screw 62 through the threaded engagement 20C, providing support for the toilet tank seat 64 and fixing the position of the tank 60.

[0137] At this point, the threaded engagement 20C is tightly clamped to the bottom side of the toilet tank seat 64, preventing it from wobbling relative to the screw 62. Therefore, after the single screw quick-install nut 100C is tightened to the bottom side of the toilet tank seat 64, even if the force applied to move the housing 10C upward is released, so that the housing 10C no longer presses against the pressing member 30C, the threaded engagement 20C will not loosen from its locked position and state to the screw 62 unless a force is applied to rotate it relative to the screw 62, thus ensuring the effectiveness of fixing the tank 60.

[0138] When the single-screw quick-install nut 100C needs to be removed from the screw 62, simply rotate the housing 10C in the opposite direction to rotate the threaded member 20C together. This allows the threaded member 20C to rotate along the screw 62 and move away from its position close to the bottom of the toilet tank seat 64. At this point, since the thread 25C of the threaded member 20C is only loosely screwed into the screw 62, the single-screw quick-install nut 100C can be easily pulled out of the screw 62. During the process of pulling out the single-screw quick-install nut 100C from the screw 62, the restoring force of the radial springs 36C on both sides of the pressing member 30C moves the body 32C out of the lateral channel 21C, preventing the pressing part 321C from obstructing the movement of the screw 62 within the threaded member 20C. The advantage of this invention is that, during the process of fixing this invention to the screw 62, the housing 10C and the screw 20C can be rotated by hand for installation, which makes it convenient for users to operate in narrow spaces and quickly lock this invention onto the screw 62.

[0139] The above description is only a preferred embodiment of the present utility model. Any equivalent changes made by applying the present utility model specification and the claims should be included within the patent scope of the present utility model.
