Description

Technical Field

[0001] The invention relates to a countertop mounting assembly and a faucet. Background Art

[0002] The installation of conventional faucets is usually carried out under the mounting plate, so professionals need to bend over, squat or lie under the dark and narrow basin for a long time and use a variety of special tools to complete it.

[0003] This installation method, which requires assembly and locking under the mounting plate, is cumbersome to operate and is both time-consuming and laborious for the faucet installer.

[0004] For example, the Chinese utility model patent application number is 201920977943.8, and the patent name is a faucet platform installation device. During installation, after the gasket, sealing ring, etc. that come with the faucet are put on the screw, the nut is screwed on the screw from bottom to top until the distance between the top of the support piece and the faucet base is slightly greater than the thickness of the mounting plate, and then the faucet water diversion hose is connected to the inner water pipe at the end of the faucet screw according to its design. After the water diversion hose, the faucet screw and the installed installation device that have been screwed on are passed through the mounting hole of the mounting plate, the faucet screw is pressed against one side of the mounting hole wall and lifted up, so that at least one of the top of the support piece is pressed against the mounting plate from bottom to top, and the faucet screw is rotated in the direction of the thread. Because the support piece is pressed by the mounting plate 1 and cannot rotate, the nut moves up along the thread and spreads the support piece together with the mounting plate, so that the diameter of the circular ring formed by the top is larger than the mounting hole of the mounting plate, and the screw is rotated until the support piece generates sufficient tension to fix the faucet on the mounting plate, and the constraint ring is clamped in the notch reserved at the top of each support piece.

[0005] For this kind of table-mounted device, the stretching piece will have the movement of contraction and expansion, and the bolts will also need to have the movement of lifting and rotation. The structural transmission and restoration movements are both relatively complicated, the cost is relatively high, and the processing and assembly are also cumbersome. Summary of the invention

[0006] The present invention provides a countertop mounting assembly and a faucet, which overcomes the shortcomings of the background technology. One of the technical solutions adopted by the present invention to solve the technical problem is:

[0007] The table mounting assembly is suitable for a table top, and the table top is provided with mounting holes. The table mounting assembly includes:

[0008] A flange plate rests against the top surface of the mounting hole and is provided with an assembly hole corresponding to the mounting hole;

[0009] A screw rod, which passes through the assembly hole and extends below the mounting hole, and can only rotate relative to the flange;

[0010] The rotation stopping member extends along the length direction of the screw rod. Its top end is connected to the flange and the screw rod, and its bottom end is only connected to the screw rod. The rotation stopping member can limit the axial movement of the screw rod;

[0011] The nut is screwed on the outer periphery of the screw rod, and the rotation stopping member can limit the rotation of the nut;

[0012] Rotate the screw rod above the tabletop, and the rotation stopping member remains stationary. Under the rotation stopping effect of the rotation stopping member, the nut can move up or down as the screw rod rotates, so that the nut presses against or leaves the lower end face of the mounting hole.

[0013] In a preferred embodiment: there is a gap between the middle part of the rotation stopping member and the screw rod, and the nut is in rotation stopping cooperation with the middle part of the rotation stopping member.

[0014] In a preferred embodiment: the nut is provided with two rotation stopping limit parts, and the two rotation stopping limit parts respectively abut against both sides of the middle part of the rotation stopping member.

[0015] In a preferred embodiment: the flange is provided with a fixing part, and the fixing part is provided with a through hole; the top end of the rotation stopping member is provided with a horizontally arranged positioning part, which abuts above the fixing part and is provided with a positioning hole corresponding to the through hole. The screw rod is inserted through the positioning hole and the through hole. The flange is also provided with a positioning cooperation part, which presses against the upper part of the positioning part to axially position the positioning part.

[0016] In a preferred embodiment: the top end of the screw rod is provided with a limiting boss, and the bottom end of the limiting boss abuts against the top end face of the positioning part.

[0017] In a preferred embodiment: the outer periphery of the positioning part is in tight fit with the wall of the assembly hole.

[0018] In a preferred embodiment: the fixing part is fixedly connected to the wall of the assembly hole and is offset from the center of the assembly hole.

[0019] In a preferred embodiment: the nut includes a generally fan-shaped nut body, which is located directly below the fixing part. A screw hole for cooperating with the screw rod is provided at a position of the nut body close to the center of the assembly hole.

[0020] In a preferred embodiment: the bottom end of the screw rod is provided with an annular groove, the nut is located above the annular groove, the bottom end of the rotation stopping member is provided with a clamping convex, and the clamping convex is clamped in the annular groove after passing over the nut.

[0021] In a preferred embodiment: the flange is also provided with a positioning ring, which extends downward along the wall of the assembly hole. When the flange abuts against the top end face of the mounting hole, the positioning ring extends into the mounting hole.

[0022] The second technical solution adopted by the present invention to solve its technical problems is: a faucet, and the faucet applies the above-mentioned on-table mounting assembly.

[0023] Compared with the background art, this technical solution has the following advantages:

[0024] 1. Rotate the screw above the tabletop. The anti-rotation member remains stationary. Under the anti-rotation action of the anti-rotation member, the nut can move upward or downward as the screw rotates, so that the nut presses against or leaves the lower end face of the mounting hole. It can be seen from this that only by rotating the screw on the tabletop can the screwing and separation of the nut and the bottom end of the tabletop be realized. The operation procedure is extremely simple. There is no need to operate the screw axially, and the operation is convenient. At the same time, the components of the mounting assembly are also fewer, the cost is reduced, and the processing and assembly are also extremely simple and convenient.

[0025] 2. There is a gap between the middle part of the anti-rotation member and the screw. The nut is in anti-rotation cooperation with the middle part of the anti-rotation member, so that when the nut moves upward, the anti-rotation member will not interfere with the nut while being able to perform anti-rotation limit on the nut.

[0026] 3. The two anti-rotation limit parts respectively abut against both sides of the middle part of the anti-rotation member to realize the circumferential anti-rotation of the nut.

[0027] 4. The positioning and fitting part presses against the upper part of the positioning part to perform axial positioning on the positioning part. Thus, the axial fixation of the anti-rotation member and the flange can be realized.

[0028] 5. The outer periphery of the positioning part is in tight fit with the hole wall of the assembly hole, which can prevent the anti-rotation member from rotating as the screw rotates, that is, perform circumferential limit on the anti-rotation member.

[0029] 6. The fixing part is fixedly connected to the hole wall of the assembly hole and is offset from the center of the assembly hole, so that the fixing part does not occupy too much space in the assembly hole, and the other space of the assembly hole can be used for the installation of the faucet assembly.

[0030] 7. The nut body is generally fan-shaped and is located directly below the fixing part, that is, the nut can make way for the installation of the faucet assembly without interference.

[0031] 8. The convexity is snapped into the annular groove after passing over the nut. Thus, when the screw rotates, the annular groove can rotate relative to the convexity, and at the same time, axial limit is performed on the bottom end of the anti-rotation member. Description of the Drawings

[0043] In the claims, description and the above-mentioned drawings of the present invention, when using terms such as "comprising", "having" and their variants, the intention is "including but not limited to".

[0044] Please refer to Figures 1 to 7, a preferred embodiment of the on - table mounting component. The on - table mounting component is applicable to the tabletop 1, and the tabletop 1 is provided with mounting holes 2.

[0045] The on - table mounting component includes: a flange 10, a screw 20, an anti - rotation member 30, and a nut 40.

[0046] The flange 10 abuts against the top surface of the mounting hole 2 and is provided with an assembly hole 11 corresponding to the mounting hole 2.

[0047] As Figure 2 shown, the flange 10 includes an annular disk body 101 with an arc surface and a hollow cylinder 102 with a cylindrical surface. The top of the hollow cylinder 102 is connected to the top of the annular disk body 101, and a reduced opening 103 is provided at the top of the hollow cylinder 102. Among them, the inside of the reduced opening 103 and the inside of the hollow cylinder 102 are the assembly hole 11. The structure of the flange 10 is not limited thereto.

[0048] In order to position the flange 10 and the tabletop 1, the flange 10 is further provided with a positioning ring 12. The positioning ring 12 extends downward along the hole wall of the assembly hole 11. When the flange 10 abuts against the top surface of the mounting hole 2, the positioning ring 12 extends into the mounting hole 2.

[0049] In this embodiment, the flange 10 is provided with a fixing portion 13, and the fixing portion 13 is provided with a perforation 14. Specifically, as Figure 2 shown, the fixing portion 13 is generally fan - shaped, is fixedly connected to the hole wall of the assembly hole 11 and is offset from the center of the assembly hole 11. That is, the central axis of the perforation 14 does not coincide with the central axis of the assembly hole 11. So that the fixing portion 13 does not occupy too much space in the assembly hole 11, and other spaces of the assembly hole 11 can be used for the installation of the faucet assembly; at the same time, the structure of the fixing portion 13 cannot be seen from the outside, and the appearance is more beautiful. The fixing portion 13 and the flange 10 can be integrally formed.

[0050] Moreover, the flange 10 is further provided with a positioning and mating portion 15. The positioning and mating portion 15 is located on the hole wall of the assembly hole 11 and above the fixing portion 13. As Figure 2 shown, the positioning and mating portion 15 is a positioning block, and there are two and they are arranged at intervals.

[0051] In order to visually identify the position of the fixing portion 13 from the outside, an arrow mark 16 can be provided on the outer periphery of the flange 10 to quickly locate the position of the fixing portion 13.

[0052] In order to ensure the sealing fit between the flange 10 and the tabletop 1, a sealing gasket 17 can be provided between the flange 10 and the tabletop 1.

[0053] The screw rod 20 extends below the mounting hole 2 after passing through the assembly hole 11, and it can only rotate relative to the flange 10. Wherein, a cross-shaped slot 21 is provided at the top end of the screw rod 20, and the screw rod 20 can be rotated by a screwdriver.

[0054] In this embodiment, an annular groove 22 is provided at the bottom end of the screw rod 20, the nut 40 is located above the annular groove 22, a clamping protrusion 31 is provided at the bottom end of the rotation stopper 30, and the clamping protrusion 31 is clamped in the annular groove 22 after passing over the nut 40. Thus, when the screw rod 20 rotates, the annular groove 22 can rotate relative to the clamping protrusion 31, and at the same time, the bottom end of the rotation stopper 30 is axially limited. Moreover, under the action of the limit boss 23 and the clamping protrusion 31, the screw rod 20 cannot move axially either.

[0055] In this embodiment, a limit boss 23 is provided at the top end of the screw rod 20, and the bottom end of the limit boss 23 abuts against the top surface of the positioning portion.

[0056] The rotation stopper 30 extends along the length direction of the screw rod 20, its top end is connected to the flange 10 and the screw rod 20, and its bottom end is only connected to the screw rod 20. The rotation stopper 30 can limit the axial movement of the screw rod 20.

[0057] In this embodiment, a horizontally arranged positioning portion 32 is provided at the top end of the rotation stopper 30. The positioning portion 32 abuts against the upper part of the fixing portion 13 and is provided with a positioning hole 33 that can correspond to the through hole 14. The screw rod 20 is inserted through the positioning hole 33 and the through hole 14, and the positioning and fitting portion 15 presses against the upper part of the positioning portion 32 to axially position the positioning portion 32. The positioning and fitting portion 15 presses against the upper part of the positioning portion 32 to axially position the positioning portion 32. Thus, the axial fixation of the rotation stopper 30 and the flange 10 can be achieved.

[0058] Moreover, the outer periphery of the positioning portion 32 is in tight fit with the hole wall of the assembly hole 11, so that the rotation stopper 30 will not rotate with the rotation of the screw rod 20, that is, the rotation stopper 30 is circumferentially limited.

[0059] In this embodiment, there is a gap between the middle part of the rotation stopper 30 and the screw rod 20, and the nut 40 is in anti-rotation cooperation with the middle part of the rotation stopper 30. As Figure 4 shown, the middle part of the rotation stopper 30 is rod-shaped and parallel to the screw rod 20. There is a gap between the middle part of the rotation stopper 30 and the screw rod 20, and the nut 40 is in anti-rotation cooperation with the middle part of the rotation stopper 30, so that when the nut 40 moves upward, the rotation stopper 30 will not interfere with the nut 40 and can anti-rotation limit the nut 40 at the same time.

[0060] The nut 40 is screwed onto the outer periphery of the screw rod 20, and the rotation-preventing member 30 can restrict the rotation of the nut 40. When the screw rod 20 is rotated above the tabletop 1, the rotation-preventing member 30 remains stationary, and the nut 40 can move upward or downward along with the rotation of the screw rod 20 under the action of preventing rotation of the rotation-preventing member 30, so that the nut 40 presses against or leaves the lower end surface of the mounting hole 2.

[0061] In this embodiment, the nut 40 is provided with two rotation-preventing and limiting portions 41, and the two rotation-preventing and limiting portions 41 respectively abut against both sides of the middle portion of the rotation-preventing member 30. The two rotation-preventing and limiting portions 41 respectively abut against both sides of the middle portion of the rotation-preventing member 30 to achieve circumferential rotation prevention of the nut 40.

[0062] In this embodiment, the nut 40 includes a nut body 44 that is generally fan-shaped. The nut body 44 is located directly below the fixing portion 13, and a threaded hole 42 that cooperates with the screw rod 20 is provided at a position of the nut body 44 close to the center of the assembly hole 11. The nut body 44 is generally fan-shaped and is located directly below the fixing portion 13. That is to say, the nut 40 can make way for the installation of the faucet assembly without interference. As Figure 2 shown, the two rotation-preventing and limiting portions 41 are rotation-preventing and limiting strips arranged vertically and are located on the outer periphery of the threaded hole 42.

[0063] In order to reduce the weight of the nut 40 and also to reduce costs, a plurality of hollow holes 43 can be provided on the nut body 44.

[0064] When not assembled, the nut 40 is located at the bottom end of the screw rod 20, as Figure 4 shown;

[0065] When the on-table mounting assembly needs to be assembled with the tabletop 1, as Figure 5 shown, the bottom end of the screw rod 20 is inserted downward from the mounting hole 2, and the bottom ends of the nut 40 and the rotation-preventing member 30 also extend into the mounting hole 2 until the flange 10 abuts against the top end surface of the mounting hole 2, and the positioning ring 12 is inserted into the mounting hole 2 to position the flange 10, as Figure 6 shown; then, the screw rod 20 is rotated forward above the tabletop 1. Since the rotation-preventing member 30 is limited in both the axial direction and the circumferential direction, the nut 40 cannot rotate along with the screw rod 20 through the cooperation of the two rotation-preventing and limiting portions 41 and the rotation-preventing member 30. At this time, the rotation of the screw rod 20 can only drive the nut 40 to move upward along the screw rod 20 until the nut 40 presses against the bottom end surface of the mounting hole 2, as Figure 7 shown, and the assembly of the on-table mounting assembly and the tabletop 1 is completed.

[0066] Similarly, when it is necessary to disassemble the component, just rotate the screw rod 20 reversely above the table surface 1, then the nut 40 can move downward along the screw rod 20 to leave the lower end surface of the mounting hole 2, and the component can be disassembled.

[0067] When the screw rod 20 is rotated above the table surface, the anti-rotation member 30 remains stationary. Under the anti-rotation action of the anti-rotation member 30, the nut 40 can move upward or downward as the screw rod 20 rotates, so that the nut 40 presses against or leaves the lower end surface of the mounting hole 2. It can be seen from this that just by rotating the screw rod 20 on the table surface 1, the screwing and separation of the nut 40 and the bottom end of the table surface 1 can be achieved. The operation procedure is extremely simple, and there is no need to operate the screw rod 20 axially, which is convenient for operation. At the same time, the components of the mounting component are fewer, the cost is reduced, and the processing and assembly are also extremely simple and convenient.

[0068] A faucet, which applies the above-mentioned above-table mounting component.

[0069] The above is only a preferred embodiment of the present invention, and thus the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
