[0002] During the installation process of most faucets on the market, you need to first insert the faucet into the designed position on the countertop, and use the faucet connector to fix the faucet on the countertop. Then connect the water supply pipe to the faucet so that water can flow into the faucet.

[0003] However, the products currently on the market still have the following problems:

[0004] 1. After the faucet is inserted into the countertop, the faucet connector is generally connected to the faucet from the bottom of the countertop and fixed to the countertop. During the assembly of the faucet connector and the faucet, the installation location is often dark and narrow, and it is difficult for the operator to observe the actual installation process. If the threads of the faucet connector and the threads at the bottom of the faucet are not correctly matched, the faucet connector is turned, which can easily cause the threads to be misaligned, thereby destroying the original thread structure and affecting the connection stability.

[0005] 2. When the faucet is threaded, the current faucet connector needs to be rotated a large number of times before the faucet connector can be tightened, which is time-consuming and laborious. Summary of the invention

[0013] Preferably, a guide groove is formed on the inner side of the connecting member body, and the screw-connected movable member is movably arranged in the guide groove;

[0014] The elastic member is arranged in the guide groove, and the elastic member pushes the threaded movable member to the upper end of the guide groove.

[0015] Preferably, at least two guide grooves are formed in the connecting member body, and a threaded movable member is disposed in each guide groove.

[0016] Preferably, the elastic member is a spring, and at least two elastic members are arranged in the guide groove;

[0018] Preferably, a rib is protrudingly formed on the peripheral side of the guide groove, and the rib and the guide groove cooperate to form a limiting groove;

[0019] A limited position protrusion is formed on the screw-connected movable part;

[0020] When the threaded movable member is disposed in the guide groove, the limiting protrusion will be placed in the limiting groove.

[0021] Preferably, the lower end of the connector body is connected to a bottom cover, the bottom cover is provided with a second through hole and a second notch penetrating the bottom cover, and the second notch leads to the second through hole;

[0022] When the bottom cover is connected to the connector body, the through hole 1 is connected to the through hole 2, and the notch 1 is connected to the notch 2;

[0023] The guide groove passes through the connecting member body downward to form an insertion opening, and the insertion opening is used to place the screw-connected movable member into the guide groove;

[0024] When the bottom cover is connected to the connector body, the bottom cover can cover the insertion port.

[0025] Preferably, a baffle and a fixing portion are protrudingly formed on the upper end surface of the bottom cover, and positioning plates are formed at both ends of the baffle;

[0031] 1. A guide groove is formed in the connector body of the present technical solution, and a screw-connected movable part and an elastic part are arranged in the guide groove. The elastic part abuts against the lower end of the screw-connected movable part, so that the screw-connected movable part can be located at the upper end of the guide groove and can also be tilted in the guide groove. When the connector body is connected to the faucet, the tilted screw-connected movable part makes it easier to align the threaded part on it with the thread on the faucet, thereby facilitating the connection of the connector body to the faucet. At the same time, since the thread on the screw-connected movable part that can be tilted can better match the thread on the faucet, it can also effectively avoid the occurrence of misaligned threads.

[0032] 2. The screw-connected movable part can move in the guide groove. Therefore, when the threaded part and the thread on the faucet fail to match accurately, that is, "misalignment" occurs, the thread on the faucet can push the screw-connected movable part to move in the guide groove, thereby reducing the torque generated between the threaded part on the screw-connected movable part and the thread on the faucet, thereby reducing the occurrence of thread deformation.

[0033] 3. The elastic part abuts against the lower end of the screw-connected movable part. When the connector body is connected to the faucet, the elastic part can push the screw-connected movable part to provide assistance, making it convenient for the user to tighten the connector body to the faucet.

[0034] 4. A gusset plate is provided on the side wall of the connector body. When the water supply pipe is placed inside the connector body through the notch, the gusset plate can be closed to prevent the water supply pipe from detaching. The connector body can also be tightened to facilitate the screw-connected movable part to fit the outside of the faucet and tighten it.

[0035] 5. A bottom cover is provided at the lower end of the connector body. After removing the bottom cover, the guide groove can be exposed, which is convenient for installing the screw-connected movable parts and elastic parts.

[0036] 6. A screwing part is also provided in the present technical solution. When the installer finds it difficult to tighten the connector by hand, a wrench can be put on the outside of the screwing part, and the connector can be rotated by the screwing part to tighten the connector.

[0037] 7. The screwing part is arranged on the bottom cover, and the screwing part has different shapes to match different tools. The installer can replace it according to the actual installation conditions, so as to facilitate the matching of different tools and the installation of the connector.

[0053] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0054] [Example 1]

[0055] like Figure 1 -and Figure 2 A connecting nut shown includes a connecting piece body 1, a through hole 11 is formed on the connecting piece body 1, and a water supply pipe is passed through the through hole 11.

[0056] A notch 12 is formed on the side wall of the connector body 1, and the notch 12 leads to the through hole 11. When installing a faucet, the water supply pipe needs to be inserted into the faucet first, and then the connector body 1 is connected to the lower end of the faucet to fix the faucet on the countertop. Therefore, by providing a notch 12 on the connector body 1, the water supply pipe can pass through the notch 12 and enter the through hole 11.

[0057] A threaded movable part 2 is movably provided inside the connector body 1, and a threaded portion 21 is formed on the threaded movable part 2. The threaded portion 21 is used to cooperate with the thread on the faucet to lock the lower end of the faucet and the connector body 1 to fix the faucet.

[0058] like Figure 1-Figure 7 As shown, a buckle plate 4 is hinged on the outer side of the connector body 1. When the buckle plate 4 is closed, the gap 12 can be closed. The buckle plate 4 can prevent the water supply pipe from detaching from the connector body 1.

[0059] Furthermore, the connector body 1 is in a "C" shape.

[0060] The other end of the buckle plate 4 is a clamping end 42 , and a clamping portion 43 is protruded from the clamping end 42 ; when the buckle plate 4 is closed, the clamping portion 43 cooperates with the clamping slot 18 , so that the clamping end 42 is clamped with the connector body 1 .

[0061] At the same time, when the clamping portion 43 is connected to the clamping groove 18, the two ends of the connector body 1 can be further tightened to reduce the diameter of the through hole 11, so that the threaded portion 21 on the threaded movable member 2 can fit more closely on the thread of the faucet.

[0062] A hinge seat 17 is formed on one side of the notch 12, and the hinge end 41 of the gusset plate 4 is hinged on the hinge seat 17. A card slot 18 is formed in a recessed manner on the other side of the notch 12.

[0063] like Figure 1-Figure 7 As shown, a buckle plate 4 is hinged on the outer side of the connector body 1. When the buckle plate 4 is closed, the gap 12 can be closed. The buckle plate 4 can prevent the water supply pipe from detaching from the connector body 1.

[0064] Reinforcing ribs 6 are formed on the outside of the connector body 1, which can improve the structural strength of the connector body 1, prevent the connector body 1 from breaking during deformation, improve the structural strength of the connector body 1, and increase the service life of the product.

[0065] like Figure 1-Figure 4 As shown, a guide groove 13 is formed on the inner side of the connector body 1 , and the threaded movable member 2 is movably disposed in the guide groove 13 .

[0066] An elastic member 5 is disposed in the guide groove 13 , and one end of the elastic member 5 abuts against the threaded movable member 2 to push the threaded movable member 2 to the upper end of the guide groove 13 .

[0067] Since the bottom end of the screw-connected movable member 2 is against the elastic member 5, when the connector body 1 is connected to the faucet, the threads on the faucet come into contact with the threads on the screw-connected movable member 2, so that the screw-connected movable member 2 can be tilted in the guide groove 13. However, through the structure of the present technical solution, since the screw-connected movable member 2 can move in the guide groove 13, when the threaded portion 21 on the screw-connected movable member 2 comes into contact with the threads on the faucet, the threads on the faucet can push the threaded portion 21, thereby tilting the threaded portion 21 on the screw-connected movable member 2, facilitating the alignment between the threaded portion 21 and the threads on the faucet, so that the threaded portion 21 and the threads on the faucet are accurately meshed, and the connector body 1 is screwed to the lower end of the faucet.

[0068] Furthermore, the threaded movable member 2 can move in the guide groove 13 even when the threads on the threaded portion 21 and the threads on the faucet are not accurately connected and squeeze each other. Since the threaded movable member 2 is pushed by the elastic member 5 and located at the upper end of the guide groove 13, the threads of the faucet can push the threaded movable member 2 to move in the guide groove 13, thereby reducing the torque generated between the threaded portion 21 and the threads on the faucet, preventing the threads from being deformed or damaged, and preventing the threads from being "misaligned".

[0069] In this embodiment, two screw-connected movable parts 2 are provided, and the two screw-connected movable parts 2 are respectively arranged in different guide grooves 13. Since the threads on the faucet may have production errors, when the connector body 1 is connected to the faucet, since the screw-connected movable parts 2 can move in the guide grooves 13, the screw-connected movable parts 2 can be more accurately matched with the threads on the faucet, thereby improving the fixing effect.

[0070] Furthermore, in this embodiment, the elastic member 5 is a spring, and at least two elastic members 5 are disposed in the guide groove 13 .

[0071] Connecting posts 22 are formed on both ends of the screw-connected movable part 2, and the upper end of the elastic part 5 is sleeved outside the connecting posts 22, so that the elastic part 5 can abut against both ends of the screw-connected movable part 2. When the connector body 1 is connected to the faucet, the screw-connected movable part 2 can be tilted more easily.

[0072] Specific as Figure 2 and Figure 5 As shown, a rib 14 is protrudingly formed on the peripheral side of the guide groove 13 , and the rib 14 and the guide groove 13 cooperate to form a limiting groove 15 .

[0073] The screw-connected movable part 2 is formed with a limited protrusion 23, and when the screw-connected movable part 2 is set in the guide groove 13, the limited protrusion 23 will be placed in the limited groove 15. Through the cooperation between the limited groove 15 and the limited protrusion 23, the screw-connected movable part 2 can be limited from being separated from the guide groove 13, so that the product can be used normally.

[0074] like Figure 1-Figure 4 As shown, the lower end of the connector body 1 is connected to a bottom cover 3 , the bottom cover 3 is provided with a second through hole 31 and a second notch 32 penetrating the bottom cover 3 , and the second notch 32 leads to the second through hole 31 .

[0075] When the bottom cover 3 is connected to the connector body 1, the through hole 11 is connected to the through hole 2 31, and the notch 12 is connected to the notch 2 32. When the bottom cover 3 is connected to the connector body 1, it is convenient to pass the notch 12 and the notch 2 32 into the through hole 1 11 and the through hole 2 31.

[0076] The guide groove 13 penetrates downward through the connector body 1 to form an insertion opening 16 . The insertion opening 16 is used to place the threaded movable member 2 and the elastic member 5 into the guide groove 13 .

[0077] When the bottom cover 3 is connected to the connector body 1 , the bottom cover 3 can shield the insertion opening 16 to prevent the screw-connected movable member 2 from being disengaged through the insertion opening 16 .

[0078] like Figure 1-Figure 7 As shown, a baffle 33 and a fixing portion 38 are protrudingly formed on the upper end surface of the bottom cover 3 , and positioning plates 34 are formed at both ends of the baffle 33 .

[0079] When the bottom cover 3 is connected to the connector body 1 , the baffle 33 and the fixing portion 38 can extend into the guide groove 13 , and the positioning plate 34 abuts against the side wall of the guide groove 13 , thereby determining the installation position of the bottom cover 3 .

[0080] Furthermore, a plug-in portion is formed on the bottom cover 3. In this embodiment, a plug-in portion 1 36 and a plug-in portion 2 37 are formed on the bottom cover 3, and a plug-in hole 1 61 and a plug-in hole 2 62 are opened on the connector body 1, wherein the plug-in hole 1 61 matches the plug-in portion 1 36, and the plug-in hole 2 62 matches the plug-in portion 2 37, which can also further determine the installation position of the bottom cover 3.

[0081] When the elastic member 5 is a spring, the structure of the fixing portion 38 is the same as that of the connecting column 22 , so that the lower end of the elastic member 5 can be sleeved outside the fixing portion 38 to further fix the position of the elastic member 5 .

[0082] Furthermore, a screwing portion 35 is protrudingly formed on the lower end surface of the bottom cover 3 .

[0083] In this embodiment, the screwing portion 35 is prism-shaped and has a plurality of abutment surfaces 351 formed thereon, so that the installer can use a tool sleeve to cover the outside of the screwing portion 35 to drive the screwing portion 35 to rotate, thereby completing the installation of the connector body 1.

[0084] like Figure 1-Figure 4 As shown, the upper end of the connector body 1 is formed with anti-slip grooves 19. After tightening, the friction between the connector body 1 and the bottom of the installation table can be increased.

[0085] [Example 2]

[0086] This embodiment is basically the same as the first embodiment, except that:

[0087] Specific as Figure 8 As shown, a plurality of abutting protrusions 352 are protruded from the screwing portion 35 on the bottom cover 3 to facilitate cooperation with different installation tools.

[0088] Furthermore, since the bottom cover 3 is detachably connected to the bottom of the connector body 1 , the installer can replace the bottom cover 3 with a screwing portion 35 of a different structure according to actual conditions, so as to cope with different installation scenarios.
