Description

Technical Field

[0001] This utility model relates to the field of toilet tank technology, and in particular to a handle connection mechanism and a toilet tank device. Background Technology

[0002] The toilet tank is equipped with a flush valve to drain water from the toilet bowl for flushing. One type of toilet tank has a handle or lever mounted on its side or front. The end of the handle or lever that extends into the tank is fitted with a rocker arm or linkage, which is connected to the flush valve via a chain. When the handle or lever is turned, the rocker arm or linkage swings, the chain lifts the float of the flush valve, and the valve begins to drain water.

[0003] For example, Chinese utility model patent CN209958453U discloses a toilet tank handle structure. This toilet tank handle structure includes a handle, a locking member, a connecting member, and a connecting rod connected in sequence. The locking member is used to fix the handle to the tank, and the connecting member is used to connect the connecting rod to the handle. The connecting rod is linked to the handle via the connecting member, and when the handle is in operation, it drives the connecting rod to open and close the flush valve.

[0004] The existing technology has the following drawbacks: because the connecting part needs to both rotate as a shaft and be axially locked, the knob and locking parts need to have a certain amount of slack to allow the connecting part to rotate. After a period of use, it is prone to wobbling. The connecting part has to bear both axial tension force and radial driving force, which makes it prone to fatigue wear and breakage.

[0070] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0071] like Figure 1-10 , Figure 14-16 and combined Figure 17-20 and Figure 22 As shown, an embodiment of the present invention provides a handle connection mechanism for assembly with the tank wall 51 of a toilet tank 5.

[0072] The handle connection mechanism includes a handle component 1, an axial tensioning and positioning component 2 having an arc-shaped through hole 211 and being axially positioned with the handle component 1, an elastic reset component 3 for driving the handle component 1 to reset, and a swing arm component 4 for connecting to the drain valve 7 in the toilet tank 5.

[0073] The handle component 1 includes a pivot element 11 that is mounted on the outside of the box wall 51 and is rotatable, a handle 12 located on the top of the pivot element 11, and an eccentric paddle 13 located on the inside of the pivot element 11.

[0074] The axial tensioning and positioning component 2 is used to clamp the inner and outer sides of the box wall 51, and the swing arm component 4 is pivotally connected to the axial tensioning and positioning component 2.

[0075] The eccentric lever 13 passes through the arc-shaped through hole 211 and is connected to the swing arm component 4. The eccentric lever 13 can swing in the arc-shaped through hole 211 and drive the swing arm component 4 to swing.

[0076] The handle connection mechanism provided by this utility model is used to be installed on the tank wall 51 of the toilet tank 5.

[0077] The handle connection mechanism includes a handle component 1, an axial tensioning and positioning component 2, an elastic reset component 3, and a swing arm component 4.

[0078] The handle assembly 1 includes a pivot element 11, a handle 12, and an eccentric lever 13. The pivot element 11 can be a pivot plate or a pivot bracket. The pivot element 11 is arranged on the outside of the toilet tank wall 51 and can rotate relative to the toilet tank wall 51. The pivot center of the pivot element 11 is coaxially arranged with the axial tensioning and positioning member 2. The handle 12 is connected to the top of the pivot element 11. The handle 12 is elongated and extends along the front-back direction when the handle assembly 1 is installed on the side of the toilet tank 5. Preferably, the handle 12 is integrally formed with the pivot element 1. The eccentric lever 13 is connected to the inside of the pivot element 11 and extends along the axial direction of the pivot element 11 to extend into the interior of the toilet tank 5 to actuate the swing arm assembly 4. The eccentric lever 13 is located on one side of the pivot center of the pivot element 11, or the eccentric lever 13 is spaced apart from the pivot center of the pivot element 11 and the two do not coincide. When the pivot element 11 is rotated by the handle 12, the eccentric paddle 13 rotates together. Preferably, the eccentric paddle 13 is integrally formed with the pivot element 11. Preferably, the cross-section of the eccentric paddle 13 is arc-shaped.

[0079] The axial tensioning and positioning component 2 is used to clamp the inner and outer sides of the box wall 51, and plays a role in axial fixation. The axial tensioning and positioning component 2 can adopt a bolt-clamp tensioning and positioning mechanism or similar structure. The clamps on the inner and outer sides are clamped on the inner and outer sides of the box wall 51. The bolt passes through the mounting groove or mounting hole of the box wall 51, and then is locked by the nut to clamp and fix the two clamps in the axial direction.

[0080] The axial tensioning positioning component 2 has an arc-shaped through hole 211 at the position corresponding to the eccentric lever 13. The size of the arc-shaped through hole 211 is larger than the size of the eccentric lever 13. The eccentric lever 13 can pass through the arc-shaped through hole 211 and can swing at a certain angle along the extension direction of the arc-shaped through hole 211.

[0081] During assembly, the pivot element 11 is mounted on the outside of the axial tensioning and positioning member 2, and the eccentric lever 13 passes through the arc-shaped through hole 211. The axial tensioning and positioning member 2 and the handle member 1 are fixed in the axial direction by a limiting structure to prevent them from separating. The limiting structure can be a limiting retaining ring 25, a limiting boss, or other similar structures.

[0082] The elastic reset element 3 is assembled between the axial tensioning and positioning member 2 and the handle member 1, and is used to drive the handle member 1 to automatically reset. The elastic reset element 3 can be a torsion spring, which is preferably connected between the pivot element 11 and the end face of the axial tensioning and positioning member 2. When the user presses the handle 12, it can overcome the force of the elastic reset element 3, causing the handle member 1 to rotate as a whole; when the user releases the force acting on the handle 12, the handle member 1 automatically resets to its initial position or initial state under the action of the elastic reset element 3.

[0083] One end of the swing arm component 4 is fitted onto the axial tensioning and positioning component 2, or mounted on one side of the axial tensioning and positioning component 2 via a pivot shaft, and is coaxially arranged with the pivot center of the pivot element 11. The other end of the swing arm component 4 is used to connect to the drain valve 7 in the toilet tank 5 via the zipper 8. The swing arm component 4 can swing or rotate relative to the axial tensioning and positioning component 2. When the other end of the swing arm component 4 swings upward, the drain valve 7 will be opened.

[0084] The eccentric lever 13 passes through the end of the arc-shaped through hole 211 and connects to the swing arm component 4. The eccentric lever 13 drives the swing arm component 4 to swing. The eccentric lever 13 can be connected to the swing arm component 4 by plugging / clamping.

[0085] When the handle 12 is pressed, the eccentric paddle 13 swings in the arc-shaped through hole 211, which in turn drives the swing arm component 4 to swing, causing the other end of the swing component 4 to swing upward, thereby opening the drain valve 7.

[0086] After the external force on the handle 12 is released, the handle component 1 automatically resets under the action of the elastic reset component 3, and at the same time drives the swing arm component 4 to swing and reset. The other end of the swing arm component 4 falls down and the drain valve 7 closes.

[0087] In this invention, the handle component 1 primarily provides the function of driving the swing arm component 4 to swing, while the axial tensioning and positioning component 2 primarily provides the function of axially tensioning and fixing it to the box wall 51, and axially positioning the handle component 1. The axial tensioning and positioning component 2 does not need to rotate, therefore it can axially lock all components, making the structure more stable. Furthermore, the axial tensioning and positioning component 2 does not need to bear the force driving the swing arm component 4 to swing, reducing fatigue wear, minimizing breakage, and extending service life.

[0088] In one embodiment, such as Figure 2 and Figure 4-8 As shown, the axial tensioning and positioning component 2 is provided with an eccentric shaft 234.

[0089] The swing arm component 4 includes a rotating sleeve 41 pivotally connected to the axial tensioning and positioning component 2, a connecting rod 42 hinged to the rotating sleeve 41, and a swing arm 43 pivotally connected to the eccentric shaft 234.

[0090] The upper end of the swing arm 43 is hinged to the lower end of the connecting rod 42, and the lower end of the swing arm 43 is used to connect to the zipper 8 of the drain valve 7. The eccentric lever 13 is connected to the rotating sleeve 41 and can drive the rotating sleeve 41 to rotate.

[0091] In this embodiment, the swing arm component 4 includes a rotating sleeve 41, a connecting rod 42, and a swing arm 43. The rotating sleeve 41 is fitted onto the axial bolt 22 of the axial tensioning and positioning component 2, or onto the shaft of the axial tensioning and positioning component 2, and arranged concentrically. The rotating sleeve 41 can rotate relative to the axial tensioning and positioning component 2. The upper end of the connecting rod 42 is hinged to one side of the rotating sleeve 41, and the lower end of the connecting rod 42 is hinged to one end of the swing arm 43. The other end of the swing arm 43 is used to connect to the zipper 8.

[0092] Specifically, the rotating sleeve 41 has an ear plate 411 on the side facing the connecting rod 42, and the upper end of the connecting rod 42 is hinged to the ear plate 411.

[0093] The axial tensioning and positioning component 2 is provided with an eccentric shaft 234, which is located on one side of the axis of the axial tensioning and positioning component 2, or in other words, the eccentric shaft 234 is located on one side of the rotating sleeve 41. The swing arm 43 is provided with a pivot sleeve 431 near its upper end, which is fitted on the eccentric shaft 234, so that the swing arm 43 can swing around the eccentric shaft 234.

[0094] The end of the eccentric lever 13 is connected to the rotating sleeve 41, for example, by plugging or snapping, and the eccentric lever 13 can drive the rotating sleeve 41 to rotate.

[0095] When the handle 12 is pressed, the eccentric paddle 13 rotates in the forward direction, causing the rotating sleeve 41 to rotate in the forward direction synchronously, and driving the connecting rod 42 to move downward. The connecting rod 42 presses the upper end of the swing arm 43, thereby causing the lower end of the swing arm 43 to tilt upward, pull up the zipper 8, and open the drain valve 7.

[0096] When the handle 12 is released, under the action of the elastic reset member 3, the eccentric paddle 13 rotates in the opposite direction, causing the rotating sleeve 41 to rotate in the opposite direction synchronously, and driving the connecting rod 42 to move upward. The connecting rod 42 pulls up the upper end of the swing arm 43, thereby causing the lower end of the swing arm 43 to fall down, the zipper 8 to fall down, and the drain valve 7 to close automatically.

[0097] This arrangement allows the swing arm 43 and the operating end 121 of the handle 12 to be on the same side or different sides, meeting different installation requirements.

[0098] In one embodiment, such as Figure 7-8 As shown, the cylindrical wall of the rotating sleeve 41 is provided with an insertion hole 412, and the eccentric lever 13 is inserted into the insertion hole 412.

[0099] In this embodiment, the cylindrical wall of the rotating sleeve 41 is provided with a insertion hole 412, which extends axially. After the eccentric lever 13 is pushed inward into place, the eccentric lever 13 is inserted into the insertion hole 412 to connect the eccentric lever 13 to the rotating sleeve 41.

[0100] In one embodiment, such as Figure 4-5 As shown, the operating end 121 of the handle 12 and the eccentric shaft 234 are on the same side of the pivot center of the pivot element 11.

[0101] Since the drain valve 7 is usually installed on the rear side wall of the toilet tank 5, the swing arm 43 usually needs to be installed in front of the drain valve 7.

[0102] The operating end 121 and the eccentric shaft 234 are located on the same side of the pivot center of the pivot element 11, so that when the handle 12 is placed on the side of the toilet tank 5, the operating end 121 extends forward so that the user can press the operating end 121.

[0103] If the operating end 121 of the handle 12 extends backward, when the user is sitting on the toilet and presses the operating end 121, he / she needs to extend his / her arm backward and use his / her middle finger and / or ten fingers to press the operating end 121, which is relatively inconvenient.

[0104] When the control terminal 121 extends forward, if the user is sitting on the toilet, they can bend their arm backward and press the control terminal 121 with their thumb, making it easy for the user to operate. Figure 5 As shown, after the operating end 121 is pressed, the eccentric paddle 13 drives the rotating sleeve 41 to rotate counterclockwise, causing the connecting rod 42 to move down, thereby pressing the upper end of the swing arm 43, causing the lower end of the swing arm 43 to tilt upward.

[0105] In one embodiment, such as Figure 4 and Figure 7-10 As shown, a pair of eccentric paddles 13 are provided on the inner side of the pivot element 11, and the pair of eccentric paddles 13 are arranged symmetrically about the central axis of the pivot element 11. Correspondingly, the axial tensioning and positioning member 2 has a pair of arc-shaped through holes 211, and each eccentric paddle 13 passes through an arc-shaped through hole 211 and is connected to the swing arm member 4.

[0106] In this embodiment, by configuring a pair of eccentric paddles 13 to actuate the swing arm component 4, the reliability of driving the swing arm component 4 to swing can be improved. The pair of eccentric paddles 13 are arranged symmetrically about the central axis of the pivot element 11.

[0107] Correspondingly, the axial tensioning and positioning member 2 is provided with a pair of arc-shaped through holes 211, which are also arranged symmetrically about the central axis of the pivot element 11. Each eccentric lever 13 passes through an arc-shaped through hole 211 and is then connected to the swing arm member 4.

[0108] Specifically, a pair of insertion holes 412 are provided on the cylindrical wall of the rotating sleeve 41, and the pair of insertion holes 412 are arranged symmetrically about the central axis of the rotating sleeve 41. The end of each eccentric lever 13 is inserted into one insertion hole 412.

[0109] In one embodiment, such as Figure 1-9 , Figure 14-16 and combined Figure 22 As shown, the axial tensioning positioning member 2 includes a first positioning element 21 for positioning on the outside of the box wall 51, an axial bolt 22 connected to the first positioning element 21, a second positioning element 23 sleeved on the axial bolt 22 for positioning on the inside of the box wall 51, and a locking nut 24 locked to the axial bolt 22.

[0110] An arc-shaped through hole 211 is provided on the first positioning element 21 and is offset on one side of the axial bolt 22.

[0111] The axial bolt 22 passes through one end of the rocker arm component 4, and the rocker arm component 4 is rotatable relative to the axial bolt 22.

[0112] The elastic reset element 3 is connected between the first positioning element 21 and the pivot element 11.

[0113] The eccentric lever 13 is axially positioned with the first positioning element 21.

[0114] In this embodiment, the axial tensioning positioning component 2 includes a first positioning element 21, an axial bolt 22, a second positioning element 23, and a locking nut 24.

[0115] The first positioning element 21 can be a positioning plate or a positioning bracket, etc., which is used to be placed on the outside of the box wall 51 and clamp the outer surface of the box wall 51 to achieve positioning installation.

[0116] An axial bolt 22 is connected to the inner side of the first positioning element 21, and is coaxially arranged with the pivot center of the pivot element 11. Preferably, the axial bolt 22 is integrally formed with the first positioning element 21. Because this bolt extends along the pivot center or axial direction of the pivot element 11, it is called an axial bolt 22.

[0117] The second positioning element 23 can be a positioning plate, positioning bracket or positioning box, etc., which is used to be arranged on the inner side of the box wall 51 and clamp the inner surface of the box wall 51 to achieve positioning installation.

[0118] The second positioning element 23 has a through hole for the axial bolt 22 to pass through.

[0119] The lock nut 24 is attached to the end of the axial bolt 22 to lock the second positioning element 23.

[0120] During assembly, the axial bolts 22 pass through the mounting grooves or mounting holes on the box wall 51 and clamp the inner and outer surfaces of the box wall 51 through the first positioning element 21 and the second positioning element 23 to achieve axial positioning, installation and tightening.

[0121] An arc-shaped through hole 211 is provided on the first positioning element 21 and passes through the first positioning element 21. The arc-shaped through hole 211 is located on one side of the axial bolt 22.

[0122] The upper end of the swing arm component 4 is sleeved on the axial bolt 22, and it can rotate or swing relative to the axial bolt 22. Specifically, the upper end of the swing arm component 4 is a rotating sleeve 41, which is sleeved on the axial bolt 22.

[0123] If the second positioning element 23 adopts a positioning plate and a positioning bracket, a clearance recess can be provided on the side of the positioning plate and positioning bracket facing away from the box wall 51 for installing the rotating sleeve 41 and achieving axial positioning with the positioning plate and positioning bracket. The locking nut 24 is pressed tightly on the back of the positioning plate and positioning bracket around the clearance recess, which will not affect the rotation or swing of the rotating sleeve 41.

[0124] If the second positioning element 23 adopts a positioning box, the rotating sleeve 41 and the connecting rod 42 are installed in the positioning box, and a notch is opened on the side of the positioning box for the swing arm 43 to extend and swing.

[0125] The elastic reset element 3 is assembled between the first positioning element 21 and the pivot element 11.

[0126] The eccentric lever 13 and the first positioning element 21 are positioned axially to prevent the handle component 1 from disengaging from the axially tensioned positioning component 2.

[0127] A limiting ring 25 is provided on the eccentric lever 13. The limiting ring 25 is blocked inside the first positioning element 21, and the pivot element 11 is blocked outside the first positioning element 21, thereby achieving axial positioning.

[0128] In one embodiment, such as Figure 5-7 , Figure 10 and combined Figure 22 As shown, the top of the first positioning element 21 is provided with a baffle 212, which is used to block the outside of the top cover 6 of the toilet tank 5, so as to prevent the top cover 6 from moving toward the side where the handle 12 is located and damaging the handle 12.

[0129] In one embodiment, such as Figure 6-7 and combined Figure 22 As shown, the inner surface of the first positioning element 21 is provided with a positioning boss 213, which is used to be assembled in the mounting groove 514 or mounting hole of the box wall 51 to support the first positioning element 21 and prevent the first positioning element 21 from shifting.

[0130] In one embodiment, such as Figure 7 , Figure 10 and Figure 12 As shown, the inner surface of the first positioning element 21 is provided with a positioning groove 214, and the second positioning element 23 is provided with a positioning claw 235. The positioning claw 235 is inserted into the positioning groove 214.

[0131] In this embodiment, the first positioning element 21 has a positioning groove 214 on the side facing the second positioning element 23, and the positioning groove 214 is preferably located above the axial bolt 22. The second positioning element 23 has a positioning claw 235 on the side facing the first positioning element 21. During assembly, the positioning claw 235 is inserted into the positioning groove 214 to connect the second positioning element 23, which can prevent the second positioning element 23 from shifting towards the side facing the axial bolt 22.

[0132] Multiple positioning slots 214 and positioning claws 235 can be configured as needed to improve the positioning and assembly effect between the second positioning element 23 and the first positioning element 21.

[0133] In one embodiment, such as Figure 2 , Figure 12 , Figure 15 and combined Figure 21-22As shown, the lower middle part of the second positioning element 23 is provided with a limiting claw 236 extending toward the box wall 51 for insertion into the limiting groove 515 of the box wall 51.

[0134] In this embodiment, a limiting claw 236 is provided on the lower middle part of the side of the second positioning element 23 facing the first positioning element 21. A limiting groove 515 is provided on the inner surface of the box wall 51, and the limiting groove 515 is located directly below the mounting groove 514 or the mounting hole. During assembly, the limiting claw 236 is inserted into the limiting groove 515 to position the second positioning element 23 and the box wall 51.

[0135] In one embodiment, such as Figure 5 , Figure 11 and Figure 13 As shown, the second positioning element 23 is provided with an adjustment component 26 for adjusting the position of the limiting claw 236, and the limiting claw 236 is connected to the adjustment component 26.

[0136] Because the dimensional error of the limiting groove 515 opened on the box wall 51 of the ceramic part is large, the position of the limiting claw 236 needs to be adjusted.

[0137] In this embodiment, an adjustment component 26 is provided on the second positioning element 23, and the limiting claw 236 is connected to the adjustment component 26 for adjusting the position of the limiting claw 236. Generally, it is only necessary to adjust the position of the limiting claw 236 along the horizontal direction, and the adjustment component 26 is used to drive the limiting claw 236 to move and adjust in the horizontal direction.

[0138] The adjusting assembly 26 may be an adjusting screw assembly, which is arranged on the surface of the second positioning element 23 and extends horizontally. The limiting pawl 236 is connected to the sliding member of the adjusting screw assembly, thereby enabling adjustment as the sliding member moves.

[0139] The second positioning element 23 adopts a positioning plate or positioning bracket. The adjusting component 26 can be located on the same side surface of the second positioning element 23 as the limiting claw 236, or it can be located on opposite sides of the second positioning element 23 as the limiting claw 236. In this case, an opening needs to be provided on the second positioning element 23 for the limiting claw 236 to pass through.

[0140] If the second positioning element 23 is a positioning box, the adjustment component 26 is preferably located inside the positioning box, and the limiting claw 236 extends out from the opening of the positioning box.

[0141] In one embodiment, such as Figure 11 and Figure 13 As shown, the adjustment assembly 26 includes a slider 261 that is slidably connected to the second positioning element 23 and an adjustment bolt 263 for driving the slider 261 to move.

[0142] The adjusting bolt 263 passes through the side through hole 238 of the second positioning element 23 and is connected to the slider 261.

[0143] The limiting claw 236 is connected to the slider 261.

[0144] In this embodiment, the adjusting assembly 26 includes a slider 261 and an adjusting bolt 263. The slider 261 is slidably connected to the second positioning element 23. A horizontally extending guide rail or guide groove may be provided on the second positioning element 23, and the slider 261 is slidably connected to the guide rail or guide groove. The limiting claw 236 is connected to the slider 261, and preferably, the two are integrally formed.

[0145] A side through hole 238 is provided on one side of the second positioning element 23 for the adjusting bolt 263 to pass through and be positioned. The adjusting bolt 263 passes through the side through hole 238 and is connected to the slider 261.

[0146] The side through hole 238 can be an internally threaded hole. The adjusting bolt 263 is threadedly connected to the side through hole 238, and the adjusting bolt 263 is pivotally connected to the slider 261. By rotating the adjusting bolt 263, the slider 261 can be moved, which in turn moves and adjusts the limiting pawl 236.

[0147] In one embodiment, such as Figure 11 and Figure 13 As shown, the slider 261 has an internal threaded hole / internal threaded groove 262, and the adjusting bolt 263 is axially fixed to the side through hole 238. The adjusting bolt 263 is threadedly connected to the internal threaded hole / internal threaded groove 262.

[0148] In this embodiment, the slider 261 is provided with an internal threaded hole or an internal threaded groove 262. The adjusting bolt 263 is axially fixed to the side through hole 238 through a slot and is threadedly connected to the internal threaded hole / internal threaded groove 262. The axial direction referred to here refers to the extension direction of the adjusting bolt 263.

[0149] In this way, when the adjusting bolt 263 is rotated, the adjusting bolt 263 will not move axially relative to the side through hole 238. Instead, the external thread of the adjusting bolt 263 interacts with the internal thread of the slider 261, causing the slider 261 to move axially relative to the adjusting bolt 263.

[0150] In one embodiment, such as Figure 11 and Figure 13 As shown, the operating end of the adjusting bolt 263 is provided with a knob 264, and the operating end is located on one side of the second positioning element 23, which makes it convenient for the user to rotate the adjusting bolt 263.

[0151] In one embodiment, such as Figure 11-13As shown, the slider 261 is located on the side of the second positioning element 23 facing away from the box wall 51, and the box wall 51 is provided with a laterally extending opening 237.

[0152] The limiting claw 236 passes through the opening 237 and can slide and adjust along the opening 237.

[0153] In this embodiment, the slider 261 is located on the side opposite to the box wall 51 or the first positioning element 21. An opening 237 needs to be provided in the lower middle part of the box wall 51. The opening 237 extends laterally or horizontally. One end of the limiting claw 236 is connected to the slider 261, and the other end passes through the opening 237 and can slide and adjust along the opening 237.

[0154] This configuration ensures the flatness of the surface of the second positioning element 23 facing the box wall 51, so that the second positioning element 23 fits snugly against the box wall 51.

[0155] In one embodiment, such as Figure 1-5 As shown, the second positioning element 23 includes a box body 231 and a box cover plate 232 detachably connected to the box body 231. A box notch 233 is provided on one side surface of the box body 231 and the box cover plate 232.

[0156] The main body 231 of the box is detachably connected to the first positioning element 21. The axial bolt 22 passes through the main body 231 and the box cover 232 in sequence, and the locking nut 24 locks the box cover 232.

[0157] One end of the swing arm component 4 is located in the cavity between the main body 231 of the box and the box cover 232, and the other end of the swing arm component 4 extends out of the box notch 233 and can swing along the box notch 233.

[0158] In this embodiment, the second positioning element 23 is a positioning box, which includes a box body 231 and a box cover 232. The box body 231 is located on the side closer to the first positioning element 21, and the box cover 232 is located on the side closer to the locking nut 24. The box cover 232 and the box body 231 are detachably connected by pins, buckles, etc. A cavity is formed between the box cover 232 and the box body 231 for installing components.

[0159] A notch 233 is provided on one side of the positioning box for the swing arm 43 of the swing arm component 4 to extend and swing.

[0160] Both the box cover plate 232 and the box body 231 are provided with through holes for the axial bolts 22 to pass through. During assembly, the box body 231 is pressed against the inner surface of the box wall 51, and the axial bolts 22 pass through the box body 231 and the box cover plate 232 in sequence, and then are locked by the lock nut 24.

[0161] The upper end of the swing arm component 4 is assembled in the cavity between the main body 231 and the cover plate 232. The upper end of the swing arm component 4 specifically includes a rotating sleeve 41 and a connecting rod 42.

[0162] The lower end of the swing arm component 4 extends through the box notch 233, and a section of the swing arm component 4 passing through the box notch 233 can swing along the box notch 233. Specifically, the swing arm 43 passes through the box notch 233, and the box notch 233 can swing along the box notch 233.

[0163] By placing the upper end of the swing arm component 4, which includes the rotating sleeve 41 and the connecting rod 42, in the positioning box, it is possible to prevent the rotating sleeve 41 from being squeezed and thus affecting its rotation or swing, and to prevent the connecting rod 42 from being interfered with by other components inside the toilet tank 5 and thus affecting its movement.

[0164] The aforementioned eccentric shaft 234 can be located on the side of the box body 231 facing the box cover 232.

[0165] The aforementioned positioning claw 235 may be located on the side of the main body 231 facing the first positioning element 21.

[0166] The aforementioned adjustment component 26 can be housed within the positioning box. Specifically, the slider 261 is slidably disposed on the side of the box body 231 facing the box cover 232, the opening 237 is located in the lower middle part of the box body 231, and the side through hole 238 is located on the side of the box body 231. Alternatively, semi-circular grooves can be provided on the sides of the box body 231 and the box cover 232 respectively, forming the side through hole 238 after docking.

[0167] The adjustment component 26 can be located in the positioning box to avoid interference from external parts.
