[0028] A quick mounting seat on a tap platform, such as Figure 1 , Figure 2 As shown, it involves an installation structure for assisting the faucet 2 to be quickly installed on the installation platform 1. It mainly installs the base assembly 4 in the installation hole 11 of the installation platform 1 first, and then the faucet 2 is installed through the valve body joint 3 installed at the faucet water inlet for quick sealing and plugging installation with the base assembly 4.

[0029] Among them, the valve body connector 3 is as follows Figure 6 The figure shows a hollow cylindrical connecting pipe, the upper end of the valve body joint 3 is screwed and connected to the water inlet of the faucet 2 through a threaded structure, and an O-ring 93 is provided between the upper end and the water inlet for connection sealing, and the outer circumferential surface of the lower end of the valve body joint 3 is provided with an outer locking component 31 and a double-pass O-ring 94 in order from top to bottom, and the outer diameter of the outer circumferential surface of the lower end of the valve body joint provided with the outer locking component is larger than the outer diameter of the outer circumferential surface of the lower end of the valve body joint provided with the double-pass O-ring, and the double-pass O-ring 94 is used for sealing with the base component 4 during quick plug-in installation, and 1 to 4 double-pass O-rings 94 can also be selected according to actual use needs, with a wire diameter of 1 mm to 4 mm.

[0030] The outer lock assembly 31 includes a conical surface 311 and a locking groove 312 which are circumferentially arranged on the outer circumferential surface of the lower end of the valve body joint 3. The conical surface is formed at the intersection of two outer circumferential surfaces of different outer diameters at the lower end of the valve body joint 3, and the locking groove 312 is located above the conical surface 311, which is an outer ring groove with a trapezoidal cross-section, and the angle formed by the two side surfaces of the trapezoid is 60 degrees to 170 degrees.

[0031] The base assembly 4 comprises a mounting sleeve 41 fixed in the mounting hole 11 and a water inlet joint 42 arranged in the mounting sleeve and having an elastic push-up tendency to move upward. The specific structure is as follows: the mounting sleeve 41 is as shown in FIG. Figure 7 The figure shows a hollow sleeve with a top rim 412. After being inserted into the mounting hole 11 from top to bottom, it is placed in the mounting hole 11 just by the top rim 412. An unlocking groove 411 is provided on the inner circumferential surface of the mounting sleeve 41. The unlocking groove is an inner ring groove circumferentially arranged on the inner circumferential surface of the mounting sleeve 41. Its cross-section is also trapezoidal, and its shape and size are the same as the locking groove 312 on the outer circumferential surface of the lower end of the valve body joint 3.

[0032] The lower end of the water inlet joint 42 is provided with a tightening nut 5, which is tightened by screwing the lower end of the water inlet joint 42 through the screw hole thread. That is, the top of the tightening nut 5 is in contact with the bottom surface of the mounting platform 1 through the double-layer sealing gasket 6 composed of a rubber gasket and a plastic gasket after tightening, and combined with the top edge 412 of the mounting sleeve 41, the mounting sleeve 41 can be fixedly installed in the mounting hole 11.

[0033] The hole wall of the screw hole extends upward to cover the lower end of the water inlet joint 42 to form an inner concave hole 51, which is more suitable for the plate with a thickness of 25 mm of the mounting platform 1.

[0034] At the same time, the threaded shaft at the lower end of the water inlet connector 42 is also used to connect the installation accessories and the water inlet braided hose, so the reserved thread length is 35 mm to 70 mm.

[0035] The water inlet joint 42 is sheathed with a return spring 95, which is a conical spring, and its upper end is pushed and installed on the outer shoulder of the water inlet joint 42, and the lower end of the return spring 95 is pushed and installed on the inner shoulder of the mounting sleeve 41. Therefore, the water inlet joint 42 can be provided with an elastic force of elastic push upward movement by the return spring 95, and a spring retaining ring 91 is also required to be provided on the inner circumferential surface of the mounting sleeve 41 to limit the water inlet joint 42 from moving upward and coming out. The spring retaining ring 91 is located above the unlocking groove 411, and the lower end of the valve body joint 3 needs to pass through the spring retaining ring 91 to be inserted into the water inlet joint 42.

[0036] The outer circumferential surface of the upper end of the water inlet joint 42 is provided with Figure 8 The inner lock assembly 43 shown includes a plurality of small holes 431 evenly distributed on the outer circumferential surface of the upper end of the water inlet connector 42, each of which is provided with a lock bead 432 movably inserted from the outer side of the small hole, and the inner side of each lock bead protrudes from the inner circumferential surface of the water inlet connector 42, but will not fall off from the inner circumferential surface of the water inlet connector. The number of the lock beads 432 is selected to be 1 to 8 according to actual use needs, and the diameter is 1 mm to 6 mm.

[0037] The water inlet joint 42 is provided with a water inlet hole 421 and a sealing shaft 7 that is elastically pushed upward to close the water inlet hole; the bottom of the water inlet hole 421 is provided with an inner tapered hole 422 that is small at the top and large at the bottom, and the top of the sealing shaft 7 is provided with a Fig. 9 As shown in the figure, the sealing cone 71 with a small top and a large bottom and the special-shaped head 72 arranged on the top of the sealing cone, the outer diameter of the sealing cone needs to be larger than the aperture of the inner tapered hole 422 and is provided with a sealing ring 8 fixedly installed, while the outer diameter of the special-shaped head 72 needs to be smaller than the aperture of the inner tapered hole 422; in this way, the sealing shaft 7 is pushed upward by the elastic jacking, which will drive the sealing cone 71 to push the sealing ring 8 to fit into the inner tapered hole 422 and close the water inlet hole 421; conversely, when the elastic jacking force of the sealing shaft 7 moving upward is overcome to drive the sealing cone 71 and the sealing ring 8 to separate from the inner tapered hole 422, water flow can be formed between the special-shaped head 72 and the inner tapered hole 422.

[0038] The elastic push upward movement of the sealing shaft 7 is that an opening and closing spring 96 is sleeved on the outer surface of the sealing shaft, the upper end of the opening and closing spring is pushed and installed on the outer shoulder of the sealing shaft 7, and the lower end of the opening and closing spring 96 is pushed and installed on the limit block 97 in the water inlet joint 42, so the opening and closing spring 96 elastically pushes the sealing shaft 7 upward to close the water inlet hole 421. An elastic retaining ring 92 is also required on the inner circumferential surface of the water inlet joint 42 to limit the limit block 97 from falling out downward.

[0039] Therefore, the working process of the present invention is as follows: when the faucet 2 is not installed, Figure 4 As shown, the sealing shaft 7 is elastically pushed upward by the opening and closing spring 96, and drives the sealing ring 8 on the sealing cone 71 to fit in contact with the inner cone hole 422 to close the water inlet hole 421.

[0040] When the faucet 2 is installed as Figure 5As shown, the lower end of the valve body joint 3 passes through the spring retaining ring 91 in the installation sleeve 41 and is inserted into the water inlet joint 42. The conical surface 311 at the lower end of the valve body joint 3 will contact and push a plurality of locking beads 432, and together drive the water inlet joint 42 to overcome the elastic pushing upward movement trend of the return spring 95 and move downward. In the process of the water inlet joint 42 moving downward, the plurality of locking beads 432 are first installed in the unlocking groove 411 and are separated from the contact of the conical surface 311. Then, as the water inlet joint 42 continues to move downward, the plurality of locking beads 432 in the unlocking groove 411 are installed in the locking groove 312 again. At this time, the lower end of the valve body joint 3 has been fully installed in the water inlet joint 42 and cannot continue to move downward. The downward thrust on the valve body joint 3 is released. The valve body joint 3 is Under the action of elastic pushing upward and reset, several locking beads 432 installed in the locking groove 312 are driven to disengage from the unlocking groove 411 at the same time, and the inner side of each locking bead 432 protrudes from the inner circumference of the water inlet connector 42 and is stuck in the locking groove 312, thereby realizing the locking of the lower end of the valve body connector 3 in the water inlet connector 42, and the double-pass O-ring 94 realizes the connection seal between the lower end of the valve body connector 3 and the water inlet connector 42 to prevent water leakage and ensure safety. At the same time, during the downward movement of the valve body connector 3, its lower end also synchronously pushes the sealing shaft 7 to open the water inlet hole 421 to let water pass. Even if the valve body connector 3 is elastically pushed upward and reset under the action of the reset spring 95, the sealing cone 7 is still separated from the inner tapered hole 422, and water can pass between the special-shaped head 72 and the inner tapered hole 422.

[0041] The present invention has a simple design structure and beautiful appearance. Since the base assembly 4 is first installed on the mounting platform 1, and then the faucet 2 is quickly sealed and plugged into the base assembly 4 through the valve body joint 3, the installation method of the faucet 2 is operated in the visible space on the mounting platform 1, that is, this installation method realizes the functions of self-locking, sealing and fixing, and effectively solves the problem of difficult operation of the traditional installation structure during installation. Therefore, not only will the installation process not be limited by the installation space, but the installation workers can also install the faucet more conveniently, quickly and labor-savingly, and the faucet has good tightness after installation.

[0042] In addition, the present invention is mainly applicable to the mounting platform with double mounting holes for open installation. The faucet must also correspond to a double-inlet faucet with a double valve body joint, which can be a double-inlet basin faucet or a double-inlet kitchen faucet, etc. The purpose of such a design is to facilitate the adjustment of the faucet to a suitable position. It only needs to realize a quick sealing connection with the base assembly through the valve body joint, and then tighten the connection. The faucet will not rotate after the installation is completed, and the single-hole single-seat design can also be applied to double-inlet faucets with any hole spacing on the market. Of course, the quick mounting seat structure of the present invention can also be used when a single-inlet faucet is installed on a mounting platform with a single mounting hole. It is just that after the valve body joint and the base assembly realize the sealing plug-in connection, a rotation lock is required to limit the rotation of the faucet after installation.

[0043] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design similar to this embodiment should be included in the protection scope of the present invention.
