Description

Technical Field

[0001] This utility model relates to the field of connector technology, and specifically to a connecting nut. Background Technology

[0002] Most faucets on the market require the faucet to be inserted into its designated position on the countertop and secured with a faucet connector before the water supply pipe is connected to the faucet to allow water to flow.

[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 usually connected to the faucet from below the countertop to fix the faucet to the countertop. During the assembly of the faucet connector and the faucet, the installation space is often dark and narrow, making it 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 properly matched, rotating the faucet connector can easily lead to misalignment of the threads, thereby damaging the original thread structure and affecting the stability of the connection.

[0005] 2. Current faucet connectors require a lot of rotations to tighten when making threaded connections to faucets, which is time-consuming and laborious. Utility Model Content

[0006] The purpose of this utility model is to provide a connecting nut that improves the current faucet connectors, which are cumbersome and inconvenient to install and prone to thread misalignment.

[0009] A buckle plate is hinged to the outer side of the main body of the connector, and the buckle plate can close the notch when closed;

[0010] A screw-in movable part is movably provided on the inner side of the main body of the connector, and the screw-in movable part is formed with a threaded portion;

[0011] An elastic element is provided on the inner side of the main body of the connector, and one end of the elastic element abuts against the screw-on movable part.

[0012] Preferably, the main body of the connector is C-shaped; one end of the buckle plate is a hinge end, and the other end of the buckle plate is a snap-fit ​​end, with a snap-fit ​​portion protruding from the snap-fit ​​end; a hinge seat is formed on one side of the notch, and the hinge end of the buckle plate is hinged to the hinge seat; a slot is formed in the other side of the notch; when the buckle plate is closed, the snap-fit ​​portion engages with the slot, causing the snap-fit ​​end to snap into the main body of the connector.

[0013] Preferably, a guide groove is formed on the inner side of the connector body, and the screw-in movable part is movably disposed in the guide groove;

[0014] The elastic element is provided in the guide groove, and the elastic element pushes the screw-in movable element to the upper end of the guide groove.

[0015] Preferably, the elastic element is a spring, and at least two elastic elements are provided in the guide groove;

[0016] The screw-in movable part has connecting posts formed on both ends, and the upper end of the elastic part is sleeved on the outside of the connecting posts.

[0017] Preferably, the guide groove has a protruding flange on its periphery, and the flange and the guide groove cooperate to form a limiting groove;

[0018] The screw-in movable part has a protruding limiting protrusion;

[0019] When the screw-in movable part is disposed in the guide groove, the limiting protrusion will be placed into the limiting groove.

[0020] Preferably, the lower end of the connector body is connected to a bottom cover, and the bottom cover has a through hole and a notch that penetrates the bottom cover, with the notch leading to the through hole.

[0021] When the bottom cover is connected to the main body of the connector, the first through hole is connected to the second through hole, and the first notch is connected to the second notch;

[0022] The guide groove extends downward through the main body of the connector to form an insertion port, which is used to place the screw-in movable part into the guide groove.

[0023] When the bottom cover is connected to the main body of the connector, the bottom cover can block the insertion port.

[0024] Preferably, the upper end face of the bottom cover is formed with a baffle and a fixing part, and the two ends of the baffle are formed with positioning plates;

[0025] When the bottom cover is connected to the main body of the connector, the baffle and the fixing part can extend into the guide groove, and the positioning plate abuts against the side wall of the guide groove.

[0026] The elastic element is fixedly connected to the fixing part.

[0027] Preferably, the bottom cover has a protruding twisting part on its lower end surface.

[0028] Preferably, the upper end of the connector body is formed with anti-slip texture.

[0029] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0030] 1. The connector body of this technical solution has a guide groove formed inside. A screw-in movable part and an elastic part are arranged within the guide groove. The elastic part abuts against the lower end of the screw-in movable part, allowing the screw-in movable part to be positioned at the upper end of the guide groove while also tilting within the guide groove. When the connector body is connected to the faucet, the tilted screw-in movable part makes it easier for its threads to align with the threads on the faucet, thus facilitating the connection between the connector body and the faucet. Simultaneously, because the threads on the tiltable screw-in movable part can better match the threads on the faucet, misalignment can be effectively avoided.

[0031] 2. The screw-on movable part can move within the guide groove. Therefore, when the threaded part and the thread on the faucet do not fit accurately and "misalignment" occurs, the thread on the faucet can push the screw-on movable part to move within the guide groove, thereby reducing the torque generated between the threaded part on the screw-on movable part and the thread on the faucet, thus reducing the occurrence of thread deformation.

[0032] 3. The elastic element abuts against the lower end of the screw-on movable part. When the main body of the connector is connected to the faucet, the elastic element can push the screw-on movable part to provide assistance, making it convenient for the user to tighten the main body of the connector onto the faucet.

[0033] 4. A snap plate is provided on the side wall of the connector body. After the water supply pipe is installed inside the connector body through the notch, the snap plate can be closed to prevent the water supply pipe from detaching. It can also tighten the connector body, making it easier for the screw-on movable parts to fit against the outside of the faucet and tighten.

[0034] 5. The lower end of the connector body is provided with a bottom cover. After removing the bottom cover, the guide groove can be exposed, which facilitates the installation of screw-on movable parts and elastic parts.

[0035] 6. This technical solution also includes a tightening part. When it is difficult for installers to tighten the connector by hand, a wrench can be placed on the outside of the tightening part, and the connector can be rotated by the tightening part to tighten the connector.

[0036] 7. The screwing part is located on the bottom cover, and the screwing part has different shapes to match different tools. The installer can change it according to the actual installation conditions, so as to facilitate the matching of different tools and the installation of the connector. Attached Figure Description

[0052] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0053] Example 1

[0054] like Figure 1 -and Figure 2 The connecting nut shown includes a connecting body 1, on which a through hole 11 is opened, and a water supply pipe is inserted through the through hole 11.

[0055] A notch 12 is formed on the side wall of the connector body 1, extending through the connector body 1 and leading to a through hole 11. When installing a faucet, the water supply pipe must first be inserted into the faucet before the connector body 1 is attached to the lower end of the faucet to fix it to the countertop. Therefore, by creating the notch 12 on the connector body 1, the water supply pipe can pass through the notch 12 and enter the through hole 11.

[0056] A screw-on movable part 2 is movably provided on the inner side of the connector body 1. The screw-on movable part 2 has a threaded part 21 formed on it. The threaded part 21 is used to engage with the thread on the faucet to lock the lower end of the faucet and the connector body 1 to fix the faucet.

[0057] like Figures 1-7 As shown, a buckle plate 4 is hinged to the outer side of the connector body 1. When the buckle plate 4 is closed, it can seal the notch 12 and prevent the water supply pipe from detaching from the connector body 1.

[0058] Furthermore, the main body 1 of the connector is C-shaped.

[0059] The other end of the buckle plate 4 is a snap-fit ​​end 42, and a snap-fit ​​part 43 is protruding from the snap-fit ​​end 42; when the buckle plate 4 is closed, the snap-fit ​​part 43 cooperates with the slot 18, so that the snap-fit ​​end 42 is snapped into the main body 1 of the connector.

[0060] At the same time, when the snap-fit ​​part 43 is connected to the slot 18, the two ends of the connector body 1 can be further tightened, reducing the diameter of the through hole 11, so that the threaded part 21 on the screw-fitting movable part 2 can fit more tightly on the thread of the faucet.

[0061] A hinge seat 17 is formed on one side of notch 12, and the hinge end 41 of the snap plate 4 is hinged to the hinge seat 17. A groove 18 is recessed on the other side of notch 12.

[0062] like Figures 1-7 As shown, a buckle plate 4 is hinged to the outer side of the connector body 1. When the buckle plate 4 is closed, it can seal the notch 12 and prevent the water supply pipe from detaching from the connector body 1.

[0063] A reinforcing rib 6 is formed on the outside of the connector body 1. The reinforcing rib 6 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.

[0064] like Figures 1-4 As shown, a guide groove 13 is formed on the inner side of the connector body 1, and the screw-on movable part 2 is movably disposed in the guide groove 13.

[0065] An elastic element 5 is provided in the guide groove 13. One end of the elastic element 5 abuts against the screw-on movable element 2, pushing the screw-on movable element 2 to the upper end of the guide groove 13.

[0066] Since the bottom end of the screw-on movable part 2 abuts against the elastic part 5, when the connecting body 1 is connected to the faucet, the threads on the faucet contact the threads on the screw-on movable part 2, allowing the screw-on movable part 2 to tilt within the guide groove 13. Through the structure in this technical solution, since the screw-on movable part 2 can move within the guide groove 13, when the threaded portion 21 on the screw-on movable part 2 contacts the threads on the faucet, the threads on the faucet can push the threaded portion 21, thereby causing the threaded portion 21 on the screw-on movable part 2 to tilt. This facilitates alignment between the threaded portion 21 and the threads on the faucet, ensuring accurate meshing and screwing the connecting body 1 to the lower end of the faucet.

[0067] Furthermore, the threaded movable member 2 can move within the guide groove 13, even when the threads on the threaded portion 21 and the threads on the faucet fail to connect accurately, causing mutual compression. 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 within the guide groove 13, thereby reducing the torque generated between the threaded portion 21 and the threads on the faucet, preventing thread deformation or damage, and avoiding the occurrence of "misaligned threads".

[0068] In this embodiment, two threaded movable parts 2 are provided, and these two threaded movable parts 2 are respectively arranged in different guide grooves 13. Since there may be manufacturing errors in the threads on the faucet, when the connector body 1 is connected to the faucet, the threaded movable parts 2 can move in the guide grooves 13, which allows the threaded movable parts 2 to more accurately engage with the threads on the faucet, thereby improving the fixing effect.

[0069] Furthermore, in this embodiment, the elastic element 5 is a spring, and at least two elastic elements 5 are provided in the guide groove 13.

[0070] Connecting posts 22 are formed on both ends of the screw-on movable part 2. The upper end of the elastic part 5 is sleeved on the outside of the connecting posts 22, so that the elastic part 5 can abut against both ends of the screw-on movable part 2. When the main body 1 of the connector is connected to the faucet, the screw-on movable part 2 can tilt more easily.

[0071] Specifically, such as Figure 2 and Figure 5 As shown, a retaining edge 14 is protruding from the periphery of the guide groove 13, and the retaining edge 14 and the guide groove 13 cooperate to form a limiting groove 15.

[0072] A limiting protrusion 23 is formed on the screw-in movable part 2. When the screw-in movable part 2 is placed in the guide groove 13, the limiting protrusion 23 will be placed in the limiting groove 15. Through the cooperation of the limiting groove 15 and the limiting protrusion 23, the screw-in movable part 2 can be prevented from disengaging from the guide groove 13, so that the product can be used normally.

[0073] like Figures 1-4 As shown, the lower end of the connector body 1 is connected to a bottom cover 3. The bottom cover 3 has a through hole 31 and a notch 32 that penetrates the bottom cover 3. The notch 32 leads to the through hole 31.

[0074] When the bottom cover 3 is connected to the main body 1 of the connector, the through hole 11 and the through hole 2 31 are connected, and the notch 12 and the notch 2 32 are connected. When the bottom cover 3 and the main body 1 of the connector are connected, it is convenient to insert the water supply pipe through the notch 12 and the notch 2 32 into the through hole 11 and the through hole 2 31.

[0075] The guide groove 13 extends downward through the main body 1 of the connector to form an insertion port 16, which is used to place the screw-on movable part 2 and the elastic part 5 into the guide groove 13.

[0076] When the bottom cover 3 is connected to the connector body 1, the bottom cover 3 can block the insertion port 16 to prevent the screw-on movable part 2 from coming off through the insertion port 16.

[0077] like Figures 1-7 As shown, the upper end surface of the bottom cover 3 is formed with a baffle 33 and a fixing part 38, and the two ends of the baffle 33 are formed with positioning plates 34.

[0078] When the bottom cover 3 is connected to the main body 1 of the connector, the baffle 33 and the fixing part 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.

[0079] Furthermore, the bottom cover 3 is also formed with a plug-in portion. In this embodiment, the bottom cover 3 is formed with a first plug-in portion 36 and a second plug-in portion 37, and the connector body 1 is provided with a first plug-in hole 61 and a second plug-in hole 62, wherein the first plug-in hole 61 matches the first plug-in portion 36, and the second plug-in hole 62 matches the second plug-in portion 37, which can further determine the installation position of the bottom cover 3.

[0080] When the elastic element 5 is a spring, the structure of the fixing part 38 is the same as that of the connecting post 22, so that the lower end of the elastic element 5 can be sleeved on the outside of the fixing part 38 to further fix the position of the elastic element 5.

[0081] Furthermore, a twisting part 35 is protruding from the lower end surface of the bottom cover 3.

[0082] In this embodiment, the screwing part 35 is prismatic and has several abutment surfaces 351 formed on it, so that the installer can use tools to put on the outside of the screwing part 35 and drive the screwing part 35 to rotate, so as to facilitate the installation of the connector body 1.

[0083] like Figures 1-4 As shown, the upper end of the connector body 1 is formed with anti-slip texture 19. After tightening, it can increase the friction between the connector body 1 and the bottom of the mounting platform.

[0084]

Example 2

[0085] This embodiment is basically the same as Embodiment 1, except that:

[0086] Specifically, such as Figure 8 As shown, the screwing part 35 on the bottom cover 3 has several abutting protrusions 352 protruding out to facilitate the use of different installation tools.

[0087] Furthermore, since the bottom cover 3 is detachably connected to the bottom of the connector body 1, installers can replace the bottom cover 3 with a screwing part 35 of different structures according to the actual situation, so as to deal with different installation scenarios.
