[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figures 1-7 As shown, a quick-installation device for a faucet includes an expansion member 2 for installation in a mounting hole 1 on a countertop. The upper end of the expansion member 2 extends out of the mounting hole 1 and has a connecting end 4 for connecting to the faucet body 3. The lower end of the expansion member 2 has several elastic flaps 5 formed on its outer periphery. An inner lining ring 7 is installed on the inner periphery of the elastic flaps 5. A lower connecting portion 8 is formed on the inner periphery of the inner lining ring 7. A screw hole 9 is provided in the lower connecting portion 8. The upper end of the expansion member 2 has an upper mounting portion 10 formed on its inner periphery. A limiting hole 11 is provided in the upper mounting portion 10. A fastener 12 is provided in the limiting hole 11. The lower end of the fastener 12 is screwed into the screw hole 9. In the actual assembly process, the expansion member 2 is first inserted into the tabletop mounting hole 1. Then, by rotating the fastener 12, the inner liner ring 7 can be moved upward on the inner circumference of the elastic flap 5 to expand the diameter of the elastic flap 5, so that the expansion member 2 is kept pressed against the inner wall of the tabletop mounting hole 1, thus realizing the quick-installation device and the mounting hole are fixedly connected. Then, the faucet body 3 is installed at the connecting end 4, thus realizing the quick installation of the faucet.

[0024] This utility model, through the design of a quick-installation device, allows the installer to fix and disassemble the quick-installation device from the tabletop simply by rotating the fastener 12 above the tabletop during the actual assembly and disassembly process. Compared with the prior art, there is no need to operate blindly under the tabletop, which simplifies the assembly and disassembly steps and operational requirements, and makes assembly convenient and simple.

[0025] The inner diameter of the elastic flap 5 gradually decreases from bottom to top, and an elastic hole 6 is provided between two adjacent elastic flaps 5. Therefore, when the fastener 12 is rotated to make the inner liner ring 7 move upward on the inner circumference of the elastic flap 5, it will expand the expansion member 2 to achieve the purpose of expansion and diameter increase, so that the inner liner ring 7, the elastic flap 5, and the table mounting hole 1 are tightly abutted together to achieve a fixing effect.

[0026] Furthermore, the outer periphery of the elastic flap 5 is formed with a mounting groove 14, and a rubber ring 15 is provided in the mounting groove 14, thereby increasing the friction between the elastic flap 5 and the inner wall of the mounting hole 1 on the table, preventing rotation, improving the fixing effect, and making it less prone to loosening.

[0027] The fastener 12 includes a screw 16 and a head 17. The head 17 is disposed on the upper end face of the limiting hole 11. The diameter of the head 17 is larger than the diameter of the limiting hole 11, which can restrict the movement of the fastener. The lower end of the screw 16 passes through the limiting hole 11 and is screwed into the screw hole 9.

[0028] An upper limit seat 18 is installed on the outer periphery of the connecting end 4. The upper limit seat 18 abuts against the upper surface of the table and is threadedly connected to the connecting end 4. The lower end surface of the upper limit seat 18 is formed with a second mounting groove 19. A rubber pad 20 is provided in the second mounting groove 19 to increase the friction between the device and the table and further fix the quick-installation device.

[0029] The upper limit seat 18 is equipped with a faucet body 3 on its outer periphery. The lower end of the faucet body 3 is formed with a sleeve portion 21 for installation on the outer periphery of the annular seat 23. A fixing member 22 is screwed into the side wall of the sleeve portion 21. The upper end of the upper limit seat 18 is formed with an annular seat 23. A fixing hole 24 for the fixing member 22 to be inserted is opened on the side wall of the annular seat 23. In the actual installation process, the quick-installation device is first fixed in the mounting hole 1 on the table, and then the faucet body 3 is inserted into the outer periphery of the annular seat 23. By rotating the fixing member 22, one end of it can be inserted into the fixing hole 24, thereby fixing the faucet body 3 and the quick-installation device.

[0030] A sealing ring 25 is provided between the sleeve part 21 and the annular seat 23 to improve the sealing performance and prevent leakage.
