[0004] To solve the above technical problems, the present invention provides a handle structure of a faucet, including: a handle, a mounting seat, a bushing, and a fixing seat; the mounting seat is used to connect to a faucet body buried in the wall, and the mounting seat can axially drive the faucet body to be positioned at a predetermined position; the mounting seat includes a through hole, and the bushing is used to limit the axial movement between the fixing seat and the through hole so that the fixing seat can rotate on the through hole; the fixing seat is used to connect the control valve shaft of the faucet, and the fixing seat can move axially relative to the control valve shaft; the handle is connected to the fixing seat to be able to rotate and drive the fixing seat to control the control valve shaft.

[0005] In a better embodiment, at least one rib is further included on the outer side of the bushing, and the rib abuts against the peripheral wall of the through hole.

[0006] In a better embodiment, the bushing can be elastically deformed; when the bushing is arranged on the through hole, the bushing drives the rib to press against the peripheral wall of the through hole.

[0007] In a better embodiment, the outer side and the inner side of the bushing are respectively connected to the mounting seat and the fixing seat through a snap structure to limit the axial movement between the fixing seat and the through hole.

[0008] In a better embodiment, the mounting seat and the faucet body are connected through a connection feature; the connection feature is an internal and external thread structure located on the faucet body and the mounting seat.

[0009] In a better embodiment, the mounting seat further includes a mounting flange, and when the mounting seat axially drives the faucet body to be positioned at a predetermined position, the mounting flange abuts against the wall.

[0010] In a better embodiment, the mounting seat further includes a mounting flange. When the mounting seat axially drives the faucet body to be positioned at a predetermined position, the mounting flange abuts against the wall; an annular wall extends along a direction away from the wall on the outer periphery of the mounting flange, and the annular wall includes at least two through holes. A mounting rod can pass through the two through holes so as to rotate the mounting seat through the mounting rod.

[0011] In a better embodiment, a connection seat is connected to the control valve shaft of the faucet; the inner side of the fixed seat includes a first connection portion, the outer side of the connection seat includes a second connection portion, and the first connection portion and the second connection portion are connected to limit the circumferential movement between the connection seat and the fixed seat, and the first connection portion can axially move relative to the second connection portion.

[0015] The present invention also provides a faucet, including the handle structure of the faucet described above.

[0016] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0017] 1. The mounting seat can axially drive the faucet body to be positioned at a predetermined position. The fixed seat can axially move relative to the control valve shaft, and the fixed seat is connected to the mounting seat through a bushing. The axial distance between the fixed seat and the mounting seat does not change. The bushing can ensure a constant gap between the fixed seat and the mounting seat, keep the rotation feel of the handle consistent, and reduce the shaking feeling of the handle. The mounting seat and the fixed seat can axially move relative to the faucet body and the control valve shaft respectively. Therefore, different depths can be adapted.

[0018] 2. The rib abuts against the peripheral wall of the through port, making the connection between the bushing and the mounting seat firm and preventing shaking.

[0019] 3. The bushing can be elastically deformed; when the bushing is arranged on the through - opening, the bushing drives the rib to press against the peripheral wall of the through - opening, ensuring that the gap between the two is as small as possible or even non - existent, thus ensuring the rotation feel.

[0020] 4. The outer and inner sides of the bushing are respectively connected to the mounting seat and the fixed seat through a snap - fit structure to limit the axial movement between the fixed seat and the through - opening, which is convenient and fast for installation.

[0021] 5. The mounting seat and the faucet body are connected through a connecting feature part; the connecting feature part is an internal and external thread structure located on the faucet body and the mounting seat, with a simple structure and fast adjustment.

[0022] 6. The mounting seat further includes a mounting flange. When the mounting seat axially drives the faucet body to be positioned at a predetermined position, the mounting flange abuts against the wall. The mounting flange can conveniently play a limiting role and can press the wall tightly to achieve a stable connection.

[0023] 7. The outer periphery of the mounting flange extends along a direction away from the wall to form an annular wall. The annular wall includes at least two through - holes, and a mounting rod can pass through the two through - holes to rotate the mounting seat through the mounting rod. The cooperation between the mounting rod and the through - holes can increase the torque for rotating the mounting seat, making the installation convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following further describes the present invention in conjunction with the drawings and specific embodiments.

[0032] Refer to Figures 1-7 Figures 1-7 , a faucet, which includes a faucet body 1, a valve structure 2, and a handle structure 3. The faucet body 1 is embedded in the wall. The faucet body 1 includes a valve chamber 11, at least one water inlet pipe 12, and at least one water outlet pipe 13. The water inlet pipe 12 and the water outlet pipe 13 are respectively connected to the valve chamber 11. The valve chamber 11 is in the shape of a cylindrical barrel and has an installation opening 111. The installation opening 111 is arranged corresponding to the wall opening on the wall. The valve structure 2 is arranged in the valve chamber 11 and is respectively connected to the water inlet pipe 12 and the water outlet pipe 13. The fluid (such as water) in the water inlet pipe 12 enters the valve structure 2 in the valve chamber 11 and passes through the valve structure 2 to enter the water outlet pipe 13. The number of the water inlet pipes 12 can be determined according to the type of the valve structure 2. For example, when the valve structure 2 is a on-off valve, the number of both the water inlet pipe 12 and the water outlet pipe 13 is one. When the valve structure 2 is a temperature control valve with two inlets and one outlet, the number of the water inlet pipes 12 is two and the number of the water outlet pipes 13 is one. One of the water inlet pipes 12 is for hot water, and the other water inlet pipe 12 is for cold water. The valve structure 2 receives the hot water and cold water from the two water inlet pipes 12 and mixes them through the water distribution plate structure inside to form mixed water at a specific temperature, and leads the mixed water to the water outlet pipe 13. The water outlet pipe 13 can be connected to a water outlet device, such as a pull-out faucet head, etc., without being limited thereto.

[0033] The valve structure 2 includes a rotating control valve shaft 21, and the user can control the valve structure 2 by rotating the control valve shaft 21.

[0034] The handle structure 3 includes a mounting seat 31, a bushing 32, a fixed seat 33, and a handle 34.

[0035] Refer to Figure 2, the mounting base 31 includes an adjusting peripheral wall 311, and the adjusting peripheral wall 311 and the mounting opening 111 can be axially interlocked to be positioned at a predetermined position, and the predetermined position can be determined according to the distance between the wall surface of the wall and the faucet body 1. The adjusting peripheral wall 311 and the mounting opening 111 are connected by a connecting feature 35. In this embodiment, the connecting feature 35 is an external thread located on the adjusting peripheral wall 311 and an internal thread located on the mounting opening 111. In some simple replacements, the connecting feature 35 can also be an internal thread located on the adjusting peripheral wall 311 and an external thread located on the mounting opening 111. The adjusting peripheral wall 311 can be screwed to the mounting opening 111 to move along its own axis to adapt to different predetermined positions. The adjusting peripheral wall 311 further includes a through hole 312 extending axially through both ends of itself. The mounting base 31 further includes a mounting flange 313 connected to the end of the adjusting peripheral wall 311 away from the mounting opening 111. The mounting flange 313 is used to abut against the wall. During installation, the adjusting peripheral wall 311 and the mounting opening 111 are screwed together so that the mounting flange 313 can abut against the wall, and the control valve shaft 21 can extend into the through hole 312. An annular wall 3131 extends along the direction away from the wall on the outer periphery of the mounting flange 313. At least two through holes 3132 are included on the annular wall 3131. A mounting rod can pass through the two through holes 3132 to rotate the mounting base 31 through the mounting rod, and the mounting rod can increase the torque for rotating the mounting base 31.

[0036] Refer to Figure 3 , the bushing 32 is used to limit the axial movement between the fixed seat 33 and the through hole 312 so that the fixed seat 33 can rotate on the through hole 312. The bushing 32 includes a bushing peripheral wall 321 that can elastically deform radially inward. In this embodiment, the bushing peripheral wall 321 includes a slot 3211 extending along its own axis. When the bushing 32 is subjected to external pressure, the slot 3211 can shrink so that the bushing 32 deforms radially inward. At least one rib 3212 is included on the outer side of the bushing peripheral wall 321, and the rib 3212 extends axially. In this embodiment, a plurality of ribs 3212 are included on the outer side of the bushing peripheral wall 321, and the plurality of ribs 3212 are arranged at intervals in the circumferential direction. The rib 3212 abuts against the peripheral wall of the through hole 312. When the bushing 32 is arranged on the through hole 312, the bushing 32 drives the rib 3212 to press against the peripheral wall of the through hole 312. Specifically, when the bushing 32 is arranged on the through hole 312, the bushing peripheral wall 321 still has a tendency to deform radially outward, so it will drive the rib 3212 to abut against the peripheral wall of the through hole 312.

[0037] Refer to Figure 3 CombineFigure 4 On the outer and inner sides of the bushing 32, the mounting base 31 and the fixed base 33 are respectively connected through a snap structure to limit the axial movement between the fixed base 33 and the through opening 312. Specifically, the first end of the peripheral wall 321 of the bushing includes a radially outwardly protruding snap block 3213, the peripheral wall of the through opening 312 includes a clamping surface 3121 for correspondingly clamping the snap block 3213, the second end of the peripheral wall 321 of the bushing is connected to a radially outwardly extending bushing ring wall 322, and the mounting flange 313 includes a fitting groove 3133 for correspondingly fitting the bushing ring wall 322. When an external pressure (a radially inward force directly applied by an installer) is applied to the peripheral wall 321 of the bushing, the peripheral wall 321 of the bushing elastically deforms radially inward. At this time, the first end of the peripheral wall 321 of the bushing is inserted into the through opening 312 from the end close to the mounting flange 313 until the snap block 3213 is clamped and matched with the clamping surface 3121. At this time, the bushing ring wall 322 and the fitting groove 3133 are correspondingly fitted. The clamping surface 3121 is an annular surface extending circumferentially along the peripheral wall of the through opening 312. Therefore, the bushing 32 can rotate on the through opening 312, or the bushing 32 can also be fixed relative to the through opening 312, as long as limiting surfaces are provided on both circumferential sides of the clamping surface 3121. The inner side of the peripheral wall 321 of the bushing includes a radially inwardly protruding first annular protrusion 3214. The fixed base 33 includes a first fixed peripheral wall 331 and a second fixed peripheral wall 332. The first fixed peripheral wall 331 and the second fixed peripheral wall 332 are sequentially connected along the axis of the fixed base 33. The radial dimension of the first fixed peripheral wall 331 is smaller than that of the second fixed peripheral wall 332. A fixed ring wall 333 is connected between the first fixed peripheral wall 331 and the second fixed peripheral wall 332. The outer side of the first fixed peripheral wall 331 includes a radially outwardly protruding second annular protrusion 3311. The first fixed peripheral wall 331 can extend into the peripheral wall 321 of the bushing from the end of the bushing having the bushing ring wall 322. The second annular protrusion 3311 correspondingly passes over the first annular protrusion 3214, and the fixed ring wall 333 correspondingly abuts against the bushing ring wall 322. At this time, the fixed base 33 is rotatably connected to the bushing 32, and the contact between the first annular protrusion 3214 and the second annular protrusion 3311 is a surface contact.

[0038] The inner side of the first fixed peripheral wall 331 includes a first connecting portion 3312. The control valve shaft 21 is further connected with a connecting seat 22. The connecting seat 22 and the control valve shaft 21 are connected by screws. The outer side of the connecting seat 22 includes a second connecting portion 221. The first connecting portion 3312 and the second connecting portion 221 are connected to limit the circumferential movement between the fixed seat 33 and the connecting seat 22. The first connecting portion 3312 can axially move relative to the second connecting portion 221. In this embodiment, both the first connecting portion 3312 and the second connecting portion 221 are spline structures.

[0039] The outer side of the second fixed peripheral wall 332 includes a third connecting portion 3321. The inner side of the handle 34 includes a fourth connecting portion 341. The third connecting portion 3321 and the fourth connecting portion 341 are connected to limit the circumferential movement between the handle 34 and the second fixed peripheral wall 332. In this embodiment, both the third connecting portion 3321 and the fourth connecting portion 341 are spline structures. The handle 34 further includes a threaded hole 342. The outer side of the second fixed peripheral wall 332 further includes an insertion hole 3322. A screw 36 is screwed into the threaded hole 342 and its end extends into the insertion hole 3322, which can limit the axial movement of the handle 34 relative to the fixed seat 33.

[0040] During installation, the mounting base 31 and the mounting opening 111 are threadedly connected. According to the distance between the mounting opening 111 and the wall surface, the axial movement between the mounting base 31 and the mounting opening 111 can adapt to different distances. The mounting base 31 is screwed to the mounting opening 111 until the mounting flange 313 abuts against the wall surface. At this time, in order to make the installation more firm, a mounting rod can be passed through the two through holes 3132 to increase the torque and facilitate tightening the mounting base 31. Place the bushing peripheral wall 321 of the bushing 32 into the through port 312 until the snap block 3213 is adaptively connected to the abutting surface 3121. Insert the first fixed peripheral wall 331 of the fixed seat 33 into the bushing 32 until the second annular protrusion 3311 correspondingly passes over the first annular protrusion 3214, and the fixed ring wall 333 correspondingly abuts against the bushing ring wall 322. The connecting seat 22 is fixed to the control valve shaft 21 by screws 36. The connecting seat 22 and the first fixed peripheral wall 331 are connected by splines. It should be noted that the connecting seat 22 can also be pre-installed on the control valve shaft 21, and this is not limited thereto. The handle 34 and the second fixed peripheral wall 332 are connected by splines. The screw 36 is screwed into the threaded hole 342 and its end extends into the insertion hole 3322. When the handle 34 is rotated, it drives the fixed seat 33 to rotate. The fixed seat 33 drives the connecting seat 22 to rotate, and the control valve shaft 21 rotates accordingly to control the valve core.
