Description

Technical field

[0001] The present invention relates to the technical field of faucets, and in particular to a fixing structure, a basin faucet and an assembly method. [Background Technology]

[0002] Basin faucets are a very common type of faucet. Traditional basin faucets require the installer to lie down or squat under the basin to install and secure it. However, the space under the basin is relatively small, and it usually requires two people to complete the installation, resulting in inconvenient installation and low efficiency.

[0003] In order to solve the problems of inconvenient installation and low installation efficiency of traditional basin faucets, the Chinese utility model patent with application date of 2022.07.19 and application number 202221860350.1 discloses a fixed base for inward-buckle installation of a faucet, including a fixed base body, a connecting fixture, a decorative cover, a fastener, a fastening screw, an anti-slip gasket and a fixing screw; a fastening screw hole seat is installed inside the fixed base body, and the fastening screw passes through the fastening screw hole seat and the fastening screw hole to fix the fixed base body to the fastener, an inner buckle is provided on one side inner wall of the fixed base body, and a first screw hole is opened on the other side wall of the fixed base body, and the connecting fixture is clamped on the inner buckle of the fixed base body through the bottom slot; the fixed base can shorten the installation time, reduce the installation strength and installation cost.

[0004] However, since basin faucets often need to be rotated during use to adjust the water outlet position, the existing mounting structure between basin faucets and basins is unstable, resulting in them easily loosening during use. In view of the above problems, the inventors of this case conducted in-depth research on this issue, which led to the creation of this case. [Summary of the invention]

[0005] The technical problem to be solved by the present invention is to provide a fixing structure, a basin faucet and an assembly method to solve the problem that the installation structure between the existing basin faucet and the basin is poor in stability, which leads to easy loosening during use.

[0006] The present invention is achieved in that:

[0007] In a first aspect, a fixing structure includes an outer sleeve, an inner sleeve, a fastener, and at least one fastening screw;

[0008] The upper end of the outer sleeve is provided with a clamping piece toward the outer ring, the outer side wall of the outer sleeve is provided with at least one first limiting slide groove along the vertical direction, and the inner side wall of the outer sleeve is provided with at least one limiting protrusion along the vertical direction; the inner sleeve is sleeved in the outer sleeve, and the inner sleeve has a connecting section supported on the upper end of the outer sleeve, the outer wall of the connecting section is provided with an external thread, and the outer side wall of the inner sleeve is provided with at least one second limiting slide groove slidably assembled with the limiting protrusion, and the second limiting slide groove extends to the lower end of the inner sleeve; the fastener is slidably assembled on the first limiting slide groove, the fastening screw passes through the clamping piece and the fastener, and the fastener is threadedly connected to the fastening screw.

[0009] Furthermore, it further comprises a tightening member and a locking member; each of the limiting protrusions is arranged at a position corresponding to one of the first limiting sliding grooves;

[0010] The upper end of any of the second limiting sliding grooves is provided with a communication opening communicating with the interior of the inner sleeve, and the side wall of the connecting section is penetrated by a protruding opening, and the protruding opening is located directly above the communication opening;

[0012] Furthermore, the number of the fastening screw, the first limiting sliding groove, the limiting protrusion and the second limiting sliding groove are all one.

[0013] Furthermore, the number of the fastening screw, the first limiting sliding groove, the limiting protrusion and the second limiting sliding groove are all two, and the two first limiting sliding grooves are arranged adjacent to each other.

[0014] Furthermore, an extension portion is provided on the lower end of the outer sleeve at a position corresponding to each of the first limiting sliding grooves, and the lower end of the first limiting sliding groove extends to the lower end of the extension portion.

[0015] Furthermore, the inner sleeve has an extension section extending beyond the lower end of the outer sleeve, and an outer wall of the extension section is provided with a limiting block.

[0016] Furthermore, the fastener is provided with a limiting slider corresponding to each first limiting groove on the side facing the outer sleeve, each limiting slider is slidably assembled on a first limiting groove, each limiting slider is penetrated by a first threaded hole, and each fastening screw is threadedly connected to a first threaded hole.

[0017] In a second aspect, a basin faucet includes a faucet body and the above-mentioned fixing structure; the lower end of the faucet body is threadedly connected to the connecting section of the fixing structure.

[0018] In a third aspect, a method for assembling a basin faucet is provided, the method comprising:

[0019] Clamping and assembling the outer sleeve and the basin: Slide the fastener onto the first limiting slot of the outer sleeve, and make the fastener located at the lower part of the first limiting slot, pass the fastening screw through the clamping piece and threadedly connect it to the fastener; pass the lower part of the outer sleeve and the fastener from top to bottom through the assembly hole on the basin, so that the fastener enters the bottom of the basin; continue to insert the outer sleeve downward into the assembly hole of the basin until the clamping piece at the upper end of the outer sleeve is supported on the upper surface of the basin; rotate the fastening screw to make the fastener slide upward along the first limiting slot until the clamping piece and the fastener clamp the basin, and then stop rotating the fastening screw;

[0020] Threaded assembly of the inner sleeve and the faucet body: thread the connecting section of the faucet body and the inner sleeve together;

[0021] Assembling the outer sleeve and the inner sleeve: align the lower end of the second limiting groove of the inner sleeve with the limiting protrusion in the outer sleeve; insert the inner sleeve downward into the outer sleeve, and support the connecting section of the inner sleeve on the upper end of the outer sleeve;

[0022] Among them, the clamping assembly of the outer sleeve and the basin and the threaded assembly of the inner sleeve and the faucet body are not in any particular order.

[0023] Furthermore, the threaded assembly of the inner sleeve and the faucet body further includes:

[0024] After the faucet body and the connecting section of the inner sleeve are threaded together, the tightening piece of the tightening member is inserted into the protruding opening, the top protrusion of the locking piece on the tightening member faces the groove wall of the second limiting slide groove, and the locking piece is locked on the groove wall of the second limiting slide groove through the locking member, so that the free end of the tightening piece passes through the protruding opening and presses against the inner wall of the lower end of the faucet body.

[0025] By adopting the technical solution of the present invention, at least the following beneficial effects are achieved:

[0026] 1. The design of the fixing structure includes an outer sleeve, a fastener slidably arranged on the first limiting slide groove on the outer side wall of the outer sleeve, and a fastening screw connecting the clamping piece on the upper end of the outer sleeve and the fastener, so that during the specific assembly, the clamping piece and the fastener can be used to clamp the upper and lower surfaces of the basin, and there is only a small gap between the outer wall of the outer sleeve and the assembly hole on the basin, which can well limit the outer sleeve. At the same time, the first limiting slide groove can effectively limit the fastener to ensure that the fastener itself will not rotate and loosen; therefore, the fixing structure of the present invention has good stability after being assembled with the basin, and is not prone to loosening or shaking during use.

[0027] 2. The fixing structure also includes an inner sleeve arranged in the outer sleeve, and the upper end of the inner sleeve has an external thread for threaded assembly with the faucet body, and the outer wall of the inner sleeve has a second limiting slide groove that slides with the limiting convex portion of the outer sleeve, so that during the specific assembly, the outer sleeve, the fastener and the fastening screw can be assembled on the basin first, and then the upper end of the inner sleeve is threadedly connected to the faucet body, and finally the inner sleeve is assembled into the outer sleeve through the second limiting slide groove and the limiting convex portion. The whole assembly process is very simple and convenient, which helps to improve the assembly efficiency, and the installer does not need to lie or squat under the basin for installation. The installation strength is low, and only one person is needed to complete the entire installation process; at the same time, because the inner sleeve and the outer sleeve are plugged in by plugging and unplugging, there is no need to use special tools for disassembly and assembly during subsequent maintenance and repair. The inner sleeve and the outer sleeve can be separated or assembled together by plugging and unplugging, so the subsequent maintenance and repair operations are also very convenient.

[0028] 3. The fixing structure also includes a tightening member and a locking member, and a protruding opening is set through the side wall of the connecting section to form a connecting opening at the upper end of the second limiting slide groove. At the same time, the tightening member is designed to include a locking piece locked on the groove wall of the second limiting slide groove and a tightening piece passing through the protruding opening, and the middle part of the locking piece has a top-butting protrusion; so that during specific assembly, when the locking piece is locked on the groove wall of the second limiting slide groove by the locking member, the free end of the tightening piece will protrude outward from the protruding opening due to the presence of the top-butting protrusion, so that the tightening piece can be used to tighten the inner wall of the lower end of the faucet body to ensure that there will be no looseness between the faucet body and the connecting section after assembly; at the same time, after assembly, the entire tightening member and the locking member can be hidden inside, which can make the external structure more simple and beautiful.

[0029] 4. The lower end of the outer sleeve is designed to extend downward at the position corresponding to the first limiting slide groove, and the first limiting slide groove is extended to the lower end of the extension. Since the extension only occupies a small part of the outer sleeve in the circumferential direction, the size of the extension is much smaller than the size of the assembly hole of the basin. Therefore, during the specific assembly, it is only necessary to slide the fastener to the position of the extension, so that the fastener and the extension can be easily passed through the assembly hole of the basin and assembled to the lower surface of the basin. In this way, the installer does not need to lie or squat under the basin for installation, and the assembly is very convenient and quick.

[0030] 5. By designing the lower end of the inner sleeve to have an extension section extending outside the outer sleeve, and providing a limit block on the outer wall of the extension section, after the inner sleeve passes through the outer sleeve, the limit block can limit the inner sleeve, thereby ensuring that the inner sleeve will not detach from the outer sleeve without applying external force to compress the limit block inward.

[0060] The outer sleeve 2 has a clamping piece 21 on its upper end extending outwardly, and the clamping piece 21 is used to clamp the basin 200 from the upper surface of the basin 200; the outer wall of the outer sleeve 2 has at least one first limiting groove 22 along the vertical direction, and the first limiting groove 22 is used to slide with the fastener 4; the inner wall of the outer sleeve 2 has at least one limiting protrusion 23 along the vertical direction, and the limiting protrusion 23 is used to slide with the inner sleeve 3;

[0061] The inner sleeve 3 is sleeved in the outer sleeve 2, and the inner sleeve 3 has a connecting section 31 supported on the upper end of the outer sleeve 2. The outer wall of the connecting section 31 is provided with an external thread 311, and the connecting section 31 is used to be screwed with the faucet body 1, so as to realize the assembly of the faucet body 1 and the inner sleeve 3 together; the outer wall of the inner sleeve 3 is provided with at least one second limiting groove 32 that is slidably assembled with the limiting protrusion 23, and the second limiting groove 32 extends to the lower end of the inner sleeve 3, so that the limiting protrusion The portion 23 can be assembled into the second limiting sliding groove 32 from the lower end of the inner sleeve 3; during specific assembly, the lower end of each second limiting sliding groove 32 can be aligned with one of the limiting protrusions 23 in the outer sleeve 2, and the inner sleeve 3 can be assembled into the outer sleeve 2 through the cooperation of the second limiting sliding groove 32 and the limiting protrusion 23; the cooperation of the second limiting sliding groove 32 and the limiting protrusion 23 can limit the inner sleeve 3, ensuring that the inner sleeve 3 cannot rotate after the inner sleeve 3 is assembled into the outer sleeve 2;

[0062] The fastener 4 is slidably assembled on the first limiting groove 22. When in use, the fastener 4 can slide up and down along the first limiting groove 22. The fastener 4 is used to clamp the basin 200 from the lower surface of the basin 200. Specifically, the fastener 4 can cooperate with the clamping piece 21 to clamp the basin 200. The fastening screw 5 passes through the clamping piece 21 and the fastener 4. The fastener 4 is threadedly connected to the fastening screw 5, so that when the fastening screw 5 is rotated, the fastener 4 can be adjusted up and down along the fastening screw 5, so that the fastener 4 can clamp the basin 200 with the clamping piece 21. Please refer to Figure 12 As shown, in a specific implementation of the present invention, an assembly hole 201 is provided through the basin 200, and the lower size of the outer sleeve 2 is smaller than the size of the assembly hole 201, so that the lower part of the outer sleeve 2 and the fastener 4 can pass through the assembly hole 201 of the basin 200 together; the upper part of the outer sleeve 2 and the assembly hole 201 are connected by a gap assembly, specifically, the outer diameter of the outer sleeve 2 is slightly smaller than the aperture of the assembly hole 201, so that the fixing structure 100 can be firmly combined with the basin 200 after assembly.

[0063] In a preferred embodiment of the present invention, the fixing structure 100 further includes a tightening member 6 and a locking member 7; each of the limiting protrusions 23 is arranged at a position corresponding to a first limiting sliding groove 22, that is, the portion where the outer wall of the outer sleeve 2 is recessed inward to form the first limiting sliding groove 22 is formed exactly on the inner wall of the outer sleeve 2 to form the limiting protrusion 23, which can reduce the structural complexity of the outer sleeve 2, thereby making it more convenient to manufacture;

[0064] A connecting opening 321 communicating with the interior of the inner sleeve 3 is provided at the upper end of any of the second limiting sliding grooves 32. A protruding opening 312 is provided through the side wall of the connecting section 31, and the protruding opening 312 is located directly above the connecting opening 321 to facilitate installation of the tightening member 6.

[0065] The tightening member 6 includes a locking piece 61 and a tightening piece 62 provided at the upper end of the locking piece 61; the middle part of the locking piece 61 is formed with a top protrusion 611 on the side of the groove wall facing the second limiting slide groove 32, and the locking piece 61 is locked to the groove wall of the second limiting slide groove 32 through the locking member 7, and the locking member 7 is located below the top protrusion 611; the tightening piece 62 passes through the protruding opening 312. Since the middle part of the locking piece 61 has the top protrusion 611, when the locking member 7 locks the locking piece 61 to the groove wall of the second limiting slide groove 32, the tightening piece 62 will pass through the protruding opening 312 under the action of the top protrusion 611, thereby tightening the inner wall of the faucet body 1 screwed to the connecting section 31. In a specific implementation of the present invention, a bolt through hole 612 is provided on the locking piece 61 , a second threaded hole 322 is provided on the groove wall of the second limiting sliding groove 32 , and the locking member 7 is a bolt.

[0066] By adopting the above technical solution of the present invention, at least the following beneficial effects are achieved:

[0067] 1. The design of the fixing structure 100 includes an outer sleeve 2, a fastener 4 slidingly arranged on the first limiting groove 22 on the outer side wall of the outer sleeve 2, and a fastening screw 5 connecting the clamping piece 21 at the upper end of the outer sleeve 2 and the fastener 4, so that during the specific assembly, the clamping piece 21 and the fastener 4 can be used to clamp the upper and lower surfaces of the basin 200, and there is only a small gap between the outer wall of the outer sleeve 2 and the assembly hole 201 on the basin 200, which can well limit the outer sleeve 2. At the same time, the first limiting groove 22 can effectively limit the fastener 4 to ensure that the fastener 4 itself will not rotate and loosen; therefore, after the fixing structure 100 of the present invention is assembled with the basin 200, it has good stability and is not prone to loosening or shaking during use.

[0068] 2. The fixing structure 100 also includes an inner sleeve 3 sleeved in the outer sleeve 2, and the upper end of the inner sleeve 3 has an external thread 311 for threaded assembly with the faucet body 1, and the outer wall of the inner sleeve 3 has a second limiting groove 32 that slides with the limiting protrusion 23 of the outer sleeve 2, so that when assembling, the outer sleeve 2, the fastener 4 and the fastening screw 5 can be assembled to the basin 200 first, and then the upper end of the inner sleeve 3 is threadedly connected to the faucet body 1, and finally the inner sleeve 3 is assembled to the outer sleeve through the second limiting groove 32 and the limiting protrusion 23. 2, the entire assembly process is very simple and convenient, which helps to improve the assembly efficiency, and the installer does not need to lie down or squat under the basin 200 for installation. The installation strength is low, and only one person is needed to complete the entire installation process; at the same time, because the inner sleeve 3 and the outer sleeve 2 are plugged in, there is no need to use special tools for disassembly and assembly during subsequent maintenance and repair. The inner sleeve 3 and the outer sleeve 2 can be separated or assembled together by plugging and unplugging, so the subsequent maintenance and repair operations are also very convenient.

[0069] When the cam 312 is in the closed position, the cam 312 is in the closed position, and the cam 312 is in the closed position, so that the cam 312 can be locked.

[0070] As a specific embodiment of the present invention, please refer to Figure 1 As shown, the number of the fastening screw 5, the first limiting groove 22, the limiting protrusion 23, and the second limiting groove 32 is 1. In this specific embodiment, since the number of the fastening screw 5, the first limiting groove 22, the limiting protrusion 23, and the second limiting groove 32 is 1, the structure of the entire fixing structure 100 is relatively simple, but the firmness after assembly is average.

[0071] As another specific embodiment of the present invention, please refer to Figure 10As shown, the number of the fastening screw 5, the first limiting chute 22, the limiting protrusion 23, and the second limiting chute 32 are all two, and the two first limiting chute 22 are arranged adjacent to each other to ensure that the fastener 4 can pass through the assembly hole 201 of the basin 200 during assembly, so that the fastener 4 enters the bottom of the basin 200. In this other specific embodiment, because the number of the fastening screw 5, the first limiting chute 22, the limiting protrusion 23, and the second limiting chute 32 are all two, the structure of the entire fixing structure 100 is more complicated, but the firmness after assembly is good, and it is more stable and reliable to use.

[0072] In a preferred embodiment of the present invention, an extension portion 24 is provided downwardly extending from the lower end of the outer sleeve 2 at a position corresponding to each first limiting sliding groove 22 , and the lower end of the first limiting sliding groove 22 extends to the lower end of the extension portion 24 . Since the fastener 4 is used to cooperate with the clamping piece 21 to clamp the basin 200, and there is only a small gap between the outer wall of the outer sleeve 2 and the assembly hole 201 on the basin 200, it is impossible to meet the requirement of assembling the fastener 4 from top to bottom; for this reason, the present invention is designed to extend the lower end of the outer sleeve 2 downward at the position corresponding to the first limiting slide groove 22, and extend the first limiting slide groove 22 to the lower end of the extension portion 24. Because the extension portion 24 only occupies a small part of the outer sleeve 2 in the circumferential direction, the size of the extension portion 24 is much smaller than the size of the assembly hole 201 of the basin 200. Therefore, during the specific assembly, it is only necessary to slide the fastener 4 to the position of the extension portion 24, so that the fastener 4 and the extension portion 24 can be easily passed through the assembly hole 201 of the basin 200 and assembled to the lower surface of the basin 200. In this way, the installer does not need to lie or squat under the basin 200 for installation, and the assembly is very convenient and quick.

[0073] In a preferred embodiment of the present invention, an extension piece 25 is provided on the inner wall of the upper end of the outer sleeve 2 at a position corresponding to the first limiting slide groove 22, and a screw through hole 251 is provided on the extension piece 25, and the screw through hole 251 is located on the inner side of the inner wall of the upper end of the inner sleeve 3. In this way, during the specific assembly, the upper end of the fastening screw 5 can be well hidden inside, thereby ensuring that the assembled fixing structure 100 is more beautiful. At the same time, the lower end of the connecting section 31 can fit with the upper end of the outer sleeve 2 without being affected by the upper end of the fastening screw 5.

[0074] In a preferred embodiment of the present invention, the inner sleeve 3 has an extension section 33 extending beyond the lower end of the outer sleeve 2. The lower end of the outer sleeve 2 refers to the lower end excluding the extension portion 24. Specifically, the lower end of the extension section 33 can be located at a position higher than the lower end of the extension portion 24. The outer wall of the extension section 33 is provided with a limit block 34. Specifically, the outer wall of the extension section 33 is provided with a plurality of limit blocks 34, and the extension section 33 is not provided with the limit block 34 at the position corresponding to the extension portion 24 of the outer sleeve 2. The outer wall of the extension section 33 is provided with a plurality of limit blocks 34. The wall is provided with interconnected avoidance slots 35 at positions above and on both sides corresponding to the limit blocks 34. In this way, during the assembly process, when the limit blocks 34 on the inner sleeve 3 enter the outer sleeve 2, they can be deformed and compressed inwardly under the extrusion of the inner wall of the outer sleeve 2, and when the limit blocks 34 on the inner sleeve 3 pass through the outer sleeve 2, they can restore the deformation outward, so that the inner sleeve 3 cannot be pulled out without applying external force to compress the limit blocks 34 inward, thereby ensuring that the inner sleeve 3 will not be separated from the outer sleeve 2 after assembly.

[0075] The present invention is designed to have an extension section 33 extending to the outside of the outer sleeve 2 at the lower end of the inner sleeve 3, and a limit block 34 is provided on the outer wall of the extension section 33, so that after the inner sleeve 3 passes through the outer sleeve 2, the limit block 34 can limit the inner sleeve 3, thereby ensuring that the inner sleeve 3 will not be separated from the outer sleeve 2 without applying external force to compress the limit block 34 inward; and when the inner sleeve 3 needs to be disassembled and separated from the outer sleeve 2, it is only necessary to press the limit block 34 inward and push the inner sleeve 3 upward to make the limit block 34 enter the interior of the outer sleeve 2, and then the inner sleeve 3 can be easily pulled up.

[0076] In a preferred embodiment of the present invention, a bottom groove wall of the first limiting sliding groove 22 is provided with an escape opening 221 at a position corresponding to the locking piece 61 , and the escape opening 221 is used to make way for the locking piece 61 and the locking member 7 .

[0077] In a preferred embodiment of the present invention, the fastener 4 is provided with a limiting slider 41 corresponding to each first limiting groove 22 on the side facing the outer sleeve 2, and each limiting slider 41 is slidably assembled on a first limiting groove 22. A first threaded hole 42 is penetrated through each limiting slider 41, and each fastening screw 5 is threadedly connected to a first threaded hole 42. During use, when the fastening screw 5 is rotated, the limiting slider 41 of the fastener 4 can slide up and down along the first limiting groove 22 for adjustment.

[0078] Example 2

[0079] See also Figures 1 to 13As shown, a preferred embodiment of a basin faucet 300 of the present invention, the basin faucet 300 includes a faucet body 1 and a fixing structure 100; the lower end of the faucet body 1 is threadedly connected to the connecting section 31 of the fixing structure 100, and at the same time, the tightening piece 62 of the fixing structure 100 is tightened against the inner wall of the lower end of the faucet body 1, so that the lower end of the faucet body 1 and the connecting section 31 of the fixing structure 100 will not loosen after being screwed together; wherein, the specific structure of the fixing structure 100, please refer to the detailed introduction of Example 1, and will not be repeated here; the faucet body 1 can adopt various faucet bodies that can be installed on the basin 200 in the prior art, and the inner wall of the lower end of the faucet body 1 needs to have an internal thread (not shown) to utilize the internal thread to screw the lower end of the faucet body 1 to the connecting section 31 of the fixing structure 100. By adopting the above-mentioned fixing structure 100 as the installation structure between the faucet body 1 and the basin 200, it can be ensured that the basin 200 and the fixing structure 100 are not prone to loosening or shaking after assembly; at the same time, the installation operation between the faucet body 1 and the basin 200 can be made simpler and more convenient, and the installer does not need to lie or squat under the basin 200 for installation, and only one person can easily complete the entire assembly operation.

[0081] Please refer to Figures 1 to 13 As shown, a preferred embodiment of the assembly method of a basin faucet 300 of the present invention includes:

[0082] The outer sleeve 2 is clamped and assembled with the basin 200: the fastener 4 is slidably assembled on the first limiting groove 22 of the outer sleeve 2. Specifically, the fastener 4 and the first limiting groove 22 can be slid together by the limiting slider 41, and the fastener 4 is located at the lower part of the first limiting groove 22, specifically, the fastener 4 is located on the first limiting groove 22 of the outer wall of the extension part 24, so that the extension part 24 and the fastener 4 are passed through the assembly hole 201 of the basin 200 from top to bottom. The fastening screw 5 passes through the clamping piece 21 and is threadedly connected to the fastener 4. Specifically, when the fixing structure 100 is equipped with two fastening screws 5, both fastening screws 5 need to be passed through the clamping piece 21 and threadedly connected together with the fastener 4; the lower part of the outer sleeve 2 (i.e., the extension part 24) and the fastener 4 are passed from top to bottom through the assembly hole 201 on the basin 200, so that the fastener 4 enters the bottom of the basin 200; the outer sleeve 2 is further inserted downward to the assembly hole of the basin 200 201, until the clamping piece 21 at the upper end of the outer sleeve 2 is supported on the upper surface of the basin 200. At this time, there is only a small gap between the outer sleeve 2 and the assembly hole 201 of the basin 200, which can well limit the outer sleeve 2 so that the outer sleeve 2 will not move horizontally; rotate the fastening screw 5 to make the fastener 4 slide upward along the first limiting groove 22 until the clamping piece 21 and the fastener 4 clamp the basin 200, and then stop rotating the fastening screw 5; similarly, when the fixing structure 100 When two fastening screws 5 are provided, both fastening screws 5 need to be rotated to ensure that the fastener 4 can slide upward along the first limiting slide groove 22 to achieve clamping; because the clamping piece 21 cooperates with the fastener 4 to clamp the basin 200, the outer sleeve 2 will be limited in the assembly hole 201 of the basin 200, and the fastener 4 will be limited in the first limiting slide groove 22. Therefore, no matter how the faucet body 1 is rotated during use, the outer sleeve 2 and the basin 200 are not easy to loosen;

[0083] Threaded assembly of the inner sleeve 3 and the faucet body 1: Thread the connecting section of the faucet body 1 and the inner sleeve 3 together;

[0084] Assembly of the outer sleeve 2 and the inner sleeve 3: Align the lower end of the second limiting groove 32 of the inner sleeve 3 with the limiting protrusion 23 in the outer sleeve 2; insert the inner sleeve 3 downward into the outer sleeve 2, and support the connecting section 31 of the inner sleeve 3 on the upper end of the outer sleeve 2. Specifically, the upper end surface of the outer sleeve 2 can be flush with the upper surface of the clamping piece 11 to better support the connecting section 31;

[0085] Among them, the clamping assembly of the outer sleeve 2 and the basin 200 and the threaded assembly of the inner sleeve 3 and the faucet body 1 have no particular order; that is, during the specific assembly, the outer sleeve 2 and the basin 200 can be clamped together first, and then the inner sleeve 3 and the faucet body 1 can be threaded together; or the inner sleeve 3 and the faucet body 1 can be threaded together first, and then the outer sleeve 2 and the basin 200 can be clamped together.

[0086] In a preferred embodiment of the present invention, in order to prevent the faucet body 1 and the inner sleeve 3 from becoming loose, the threaded assembly of the inner sleeve 3 and the faucet body 1 further includes:

[0087] After the faucet body 1 and the connecting section of the inner sleeve 3 are threaded together, the tightening piece 62 of the tightening member 6 is inserted into the protruding opening 312, and the top protrusion 611 of the locking piece 61 on the tightening member 6 faces the groove wall of the second limiting slide groove 32, and the locking piece 61 is locked on the groove wall of the second limiting slide groove 32 through the locking member 7, so that the free end of the tightening piece 62 passes through the protruding opening 312 and is tightened against the inner wall of the lower end of the faucet body 1, so that the faucet body 1 and the inner sleeve 3 can be reliably combined together to ensure that they will not loosen during use.
