Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0046] Embodiment 1

[0047] Please refer to Figure 1, the quickly installable water outlet device provided in this embodiment includes: a regulating valve 200 and a hand-tightening nut 100. The regulating valve 200 and the hand-tightening nut 100 cooperate with each other and are fixedly installed in the installation hole of the sanitary ware countertop 300. The installation hole of the sanitary ware countertop 300 is a single hole. Specifically, the regulating valve 200 includes: an upper valve body 201 and a lower valve external thread body 202. A handle 203 for operating the valve body 201 is provided on the valve body 201. A water pipe extends downward from the lower end of the valve body 201 of the regulating valve 200. The water pipe includes a hot water valve inlet pipe 500a and a cold water valve inlet pipe 500b. The distal ends of the hot water valve inlet pipe 500a and the cold water valve inlet pipe 500b are respectively communicated with an external hot water source and a cold water source. The valve external thread body 202 of the regulating valve 200 cooperates with the hand-tightening nut 100, and the regulating valve 200 can be quickly fixed on the sanitary ware countertop 300. When in use, control the handle 203 on the valve body 201 of the regulating valve 200 to open the valve body 201 of the regulating valve 200, communicate the hot water valve inlet pipe 500a communicating with the external hot water source, and the cold water valve inlet pipe 500b communicating with the external cold water source. The valve body 201 of the regulating valve 200 mixes the received hot water and cold water, and the mixed hot water and cold water flow out through the water outlet pipe of the regulating valve 200.

[0048] For the quick installation of the water outlet device, first, above the sanitary ware countertop 300, pass the valve external thread body 202 of the regulating valve 200 of the water outlet device and the downward-extending water pipe from above the sanitary ware countertop 300 to below the sanitary ware countertop 300; then, below the sanitary ware countertop 300, put the hand-tightening nut 100 on the water pipe and the valve external thread body 202 of the regulating valve 200 from bottom to top in sequence; then, manually tighten the hand-tightening nut 100 to quickly fix the regulating valve 200 on the sanitary ware countertop 300; finally, respectively communicate the distal ends of the hot water valve inlet pipe 500a and the cold water valve inlet pipe 500b with an external hot water source and a cold water source to complete the installation.

[0049] In this embodiment, the outer diameter dimension of the lower part of the valve body 201 of the regulating valve 200 is larger than the inner diameter dimension of the installation hole of the sanitary ware countertop 300; the outer diameter dimension of the valve external thread body 202 of the regulating valve 200 is smaller than the inner diameter dimension of the installation hole of the sanitary ware countertop 300. Therefore, the valve body 201 of the regulating valve 200 is located above the sanitary ware countertop 300, and the valve external thread body 202 of the regulating valve 200 is located below the sanitary ware countertop 300.

[0050] In the water outlet device of this embodiment, the regulating valve 200, the valve body 201, the valve external thread body 202, the handle 203 and the water outlet pipe are integrated into one body, which can be called an integrated faucet. The valve external thread body 202 therein cooperates with the hand-tightening nut 100 to install the integrated faucet in the single hole of the sanitary ware countertop 300.

[0051] It should be noted that the water pipe extending downward from the lower end of the valve body 201 of the regulating valve 200 of the integrated faucet. In this embodiment, the water pipe includes a double pipe of a hot water valve inlet pipe 500a and a cold water valve inlet pipe 500b, or it can also be a single water pipe. The distal end of the single water pipe can be connected to a tap water source. At this time, the regulating valve 200 can control the water flow rate of the integrated faucet.

[0052] As Figure 1 and Figure 2 shown, the hand-tightening nut 100 of this embodiment includes: an annular pressing plate 1, a nut ring body 2, and a hexagonal skirt 3 connected in sequence from top to bottom, and they are all coaxially arranged. Among them, the axial dimension of the nut ring body 2 is greater than the radial dimension of the nut ring body 2. Preferably, the axial dimension of the nut ring body 2 is about 1.5 to 2 times the outer diameter dimension of the nut ring body 2. When the hand-tightening nut 100 is threadedly connected to the external thread body 202 of the regulating valve 200, it is convenient for the user to hold and rotate. The annular pressing plate 1 provided at the top of the nut ring body 2 is a ring-shaped plate, and its inner edge is connected to the top of the nut ring body 2. The outer diameter dimension of the annular pressing plate 1 is greater than the outer diameter dimension of the nut ring body 2. The function of the annular pressing plate 1 is that after the hand-tightening nut 100 is locked, it can increase the contact area between the hand-tightening nut 100 and the surface of the sanitary ware table 300, and increase the friction area to prevent loosening. A hexagonal skirt 3 is provided at the bottom of the nut ring body 2, that is, the upper part of the hexagonal skirt 3 is connected to the bottom of the nut ring body 2. The hexagonal skirt 3 is an outer polygon, preferably an outer hexagonal side. The function of the hexagonal skirt 3 is: when the hand-tightening nut 100 is locked, it can increase the torque for twisting the hand-tightening nut 100.

[0053] As Figure 3 shown, further, a plurality of reinforcing ribs 4 are distributed between the outer surface of the nut ring body 2 and the lower surface of the annular pressing plate 1. Preferably, the plurality of reinforcing ribs 4 are evenly distributed between the outer surface of the nut ring body 2 and the lower surface of the annular pressing plate 1. The reinforcing ribs 4 can improve the rigidity of the annular pressing plate 1. Specifically, each reinforcing rib 4 is approximately triangular. The three sides of the reinforcing rib 4 are a radial side 41, an axial side 42, and an arc side 43 respectively. The radial side 41 extends radially along the lower surface of the annular pressing plate 1; the axial side 42 connects the radial side 41 and extends along the generatrix of the outer surface of the nut ring body 2; the arc side 43 connects the end of the radial side 41 and the end of the axial side 42 and is concave inward to form the arc side 43.

[0054] As Figure 3 shown, at the connection between the lower surface of the annular pressing plate 1 and the outer surface of the nut ring body 2, a reinforcing ring 7 is provided. The reinforcing ring 7 is used to improve the connection strength between the annular pressing plate 1 and the nut ring body 2.

[0055] As Figure 1 and Figure 4As shown, an internal thread 21 is provided in the inner hole of the upper section of the nut ring body 2. The internal thread 21 of the nut ring body 2 is in threaded connection with the valve external thread body 202 of the regulating valve 200 located below the sanitary ware tabletop 300, that is, the nut ring body 2 and the valve external thread body 202 of the regulating valve 200 are in threaded connection. The internal thread 21 in the inner hole of the upper section of the nut ring body 2 extends upward to the inner surface of the annular pressing plate 1, and the inner diameter of the annular pressing plate 1 is equal to the inner diameter of the nut ring body 2. The radial dimension of the thread bottom line of the internal thread 21 of the nut ring body 2 is smaller than the radial dimension of the inner hole of the non-internal thread section of the nut ring body 2.

[0056] As Figure 1 , Figure 5 , Figure 6 and Figure 7 shown, a number of radial convex lines 5 are distributed on the upper surface of the annular pressing plate 1. The radial convex lines 5 are used to enhance the friction between the hand-tightening nut 100 and the lower surface of the sanitary ware tabletop 300, so that the hand-tightening nut 100 is not easily loosened after being in threaded connection with the valve external thread body 202 of the regulating valve 200. The radial convex lines 5 on the upper surface of the annular pressing plate 1 are radially distributed. The inner end of each radial convex line 5 is basically flush with the inner edge of the annular pressing plate 1, and its outer end is close to the outer edge of the annular pressing plate 1.

[0057] Furthermore, the cross-sectional area of each radial convex line 5 gradually increases from the top to the bottom. The top of the radial convex line 5 is a flat surface or an arc surface. Preferably, the top of the radial convex line 5 is an arc surface.

[0058] As Figure 1 and Figure 3 shown, in this embodiment, the internal radial dimension of the hexagonal skirt sleeve 3 is larger than the radial dimension of the inner hole of the non-internal thread section of the nut ring body 2, and the minimum external radial dimension of the hexagonal skirt sleeve 3 is larger than the external radial dimension of the nut ring body 2. On the two walls of the two parallel hexagonal planes of the hexagonal skirt sleeve 3, force-applying rod holes 6 perpendicular to the axis of the nut ring body 2 are respectively provided. The two force-applying rod holes 6 are coaxial. The force-applying rod holes 6 cooperate with a tool rod to increase the maximum torque for locking the hand-tightening nut.

[0059] During use, the valve external thread body 202 of the regulating valve 200 of the water outlet device cooperates with the hand-tightening nut 100. The user holds the nut ring body 2 of the hand-tightening nut 100 with the hand and rotates it, so that the hand-tightening nut 100 is in threaded connection with the valve external thread body 202 of the regulating valve 200, and the regulating valve 200 is fixed on the sanitary ware tabletop 300.

[0060] Furthermore, by using an adjustable wrench or an open-end wrench to cooperate with the hexagonal skirt sleeve 3 to rotate, or by using a tool rod to cooperate with the force-applying rod holes 6, the torque for twisting the hand-tightening nut 100 is increased. The hand-tightening nut 100 cooperates with the valve external thread body 202 of the regulating valve 200, so that the regulating valve 200 is more firmly locked on the sanitary ware tabletop 300.

[0061] As Figure 2 , Figure 3 , Figure 4 and Figure 8 shown, for the hand-twist nut 100 of the water outlet device in this embodiment, its annular pressing plate 1, radial convex lines 5, reinforcing ring 7, reinforcing ribs 4, nut ring body 2 and hexagonal skirt sleeve 3 are integrally formed, and a plastic material is used, preferably integrally formed with a high-toughness plastic material. The hand-twist nut 100 has the characteristics of high strength, high toughness and anti-aging property, which is beneficial to extend its service life.

[0062] The water outlet device of this embodiment is an integrated faucet for cold and hot water inlet. In the prior art, tools such as wrenches and screwdrivers are used to assemble the faucet body, gasket and nut. Since there are many parts and the operation is carried out in a narrow space under the countertop, it is time-consuming and laborious, and the installation efficiency is low. As Figure 1 shown, for the integrated faucet of the water outlet device of this embodiment, the valve body 201 of the regulating valve 200 of the integrated faucet is located above the sanitary ware countertop 300, and the external threaded body 202 of the regulating valve 200 passes through to the lower part of the sanitary ware countertop 300. By manually screwing the hand-twist nut 100, the integrated faucet can be fixed on the sanitary ware countertop 300. The advantages are: simple and convenient installation, and high efficiency.

[0064] Please refer to Figure 1 and Figure 9 , the same as that in Embodiment One for the quick-installation water outlet device provided in this embodiment is that the structure of the hand-twist nut 100 adopted by the water outlet device is the same. Therefore, the structure of the hand-twist nut 100 will not be described in detail. The difference is that the water outlet device in Embodiment One is an integrated faucet, and the integrated faucet is installed in a single hole of the sanitary ware countertop 300; the water outlet device in this embodiment is a split faucet, and the two regulating valves 200 and a water outlet elbow 400 of the split faucet are respectively installed in three installation holes of the sanitary ware countertop 300.

[0065] As Figure 9 shown, in this embodiment, the quick-installation water outlet device includes: a water outlet elbow 400, a regulating valve 200 and a hand-twist nut 100, which are installed on a three-hole sanitary ware countertop 300.

Among them, the first hand-tightening nut 101 and the second hand-tightening nut 102 are respectively used to lock the hot water valve 200a and the cold water valve 200b, and the third hand-tightening nut 103 is used to lock the water outlet elbow 400. The structures of the three hand-tightening nuts 100 are the same. To distinguish the above three hand-tightening nuts 100, hand-tightening nuts of different colors can be used for distinction. For example: the first hand-tightening nut 101 for locking the hot water valve 200a is red, the second hand-tightening nut 102 for locking the cold water valve 200b is blue, and the third hand-tightening nut 103 for locking the water outlet elbow 400 is black.

[0070] The water outlet device of this embodiment is a split faucet. In the prior art, for the installation of a split faucet, tools such as a wrench and a screwdriver are used to assemble the regulating valve, the water outlet elbow, the gasket, and the nut. Due to the large number of fittings and the operation in the narrow space under the countertop, it is time-consuming and laborious, and the installation efficiency is low. For the split faucet of the water outlet device in this embodiment, the hot water valve 200a, the water outlet elbow 400, and the cold water valve 200b respectively pass through the left, middle, and right three installation holes of the sanitary ware countertop 300 from above the sanitary ware countertop 300. The valve external thread body 202 of the hot water valve 200a, the head external thread body 401 of the water outlet elbow 400, and the valve external thread body 202 of the cold water valve 200b are all located under the sanitary ware countertop 300 and cooperate with the hand-tightening nut 100. By manually screwing the hand-tightening nut 100, the split faucet can be fixed on the sanitary ware countertop 300. The distal ends of the hot water valve outlet pipe 600a of the hot water valve 200a, the distal end of the cold water valve outlet pipe 600b, and the distal end of the head inlet pipe 402 of the water outlet elbow 400 are quickly connected through the quick-connect tee 700. The operation is simple and the installation efficiency is high.
