[0030] First embodiment

[0031] Please refer to Figures 1 to 3 The present embodiment provides a locking device, including a base 1, a locking nut 4 and a screw rod 2, wherein the base 1 is provided with a first screw hole 10 and a first locking hole 11, the locking nut 4 is provided with a second locking screw hole 41 and a locking nut positioning portion 42, the screw rod 2 is threadedly connected with the first screw hole 10 and the second screw hole, and a locking area is provided between the base 1 and the locking nut 4; a positioning tooth 43 for increasing friction is provided on one side of the locking nut 4 close to the locking area, and the positioning tooth 43 extends into the locking area.

[0032] The locking device provided by the embodiment of the utility model is provided with a locking area, and the part to be locked can be placed in the locking area. The base 1 and the locking nut 4 are respectively arranged on both sides of the part to be locked. The initial fixation of the position of the base 1 and the locking nut 4 is achieved by the screw 2. The screw 2 is rotated to adjust the distance between the base 1 and the locking nut 4. As the distance between the base 1 and the locking nut 4 gradually decreases, the locking device is gradually locked on the part to be locked, which is beneficial to improving the disassembly and assembly efficiency of the locking device.

[0033] During the locking process of the locking device, the positioning teeth 43 provided in the embodiment of the utility model gradually increase the pressure between the part to be locked, which is beneficial to improve the firmness of the fit between the part to be locked and the locking device, so that in the later stage of installation or disassembly, the auxiliary positioning structure can be used to avoid the rotation of the locking nut 4, and the auxiliary positioning structure is only needed when the locking nut 4 can rotate with the screw 2 in the early stage of locking.

[0034] In some embodiments, the locking device can be configured with two L-wrenches, one large and one small, one for positioning the locking nut 4 and the other for rotating the screw 2.

[0035] In an optional embodiment, a locking rod 3 is further included, and the locking rod 3 is inserted into the first locking hole 11 and the circumferential surface of the locking rod 3 abuts against the locking nut positioning portion 42 .

[0036] In the embodiment of the utility model, the locking rod 3 passes through the first locking hole 11 to achieve relative fixation of the locking rod 3 and the base 1, and the peripheral surface of one end of the locking rod 3 abuts against the locking nut 4, so that when the locking nut 4 approaches the screw 2 under the action of the screw 2, it only moves along the direction of the screw 2, and does not rotate along the screw 2, which is conducive to improving the efficiency of disassembly and assembly, and at the same time improving the convenience of disassembly and assembly. It should be noted that the screw 2 in the utility model only needs to be used during the disassembly and assembly process, and the screw 2 can be removed after the disassembly and assembly is completed.

[0037] In an optional embodiment, a ridge 44 is provided on the locking nut, and the positioning teeth 43 are provided on the ridge 44 .

[0038] The presence of the ridge 44 makes the distance between the positioning tooth 43 and the plane of the locking nut 4 close to the locking area larger. If the surface strength of the part to be locked is low and easy to deform, such as wood, the positioning tooth 43 can be inserted into the shallow surface layer of the part to be locked, thereby improving the firmness between the locking device and the part to be locked; or when the part to be locked has a low flatness and interferes with the locking nut 4, the positioning tooth 43 can also contact the surface of the part to be locked to avoid failure of the positioning tooth 43.

[0039] In order to ensure the firmness of the locking device, the positioning teeth 43 are preferably made of a material with higher strength, such as alloy.

[0040] In an optional embodiment, the positioning teeth 43 are arranged at the edge of the locking nut 4 .

[0041] The positioning teeth 43 are arranged at the edge of the locking nut 4 , so that the distance between the positioning teeth 43 and the axis of the screw 2 is relatively far. Under the same torque conditions, the torque is larger and the force on the positioning teeth 43 is smaller, which is beneficial to improving the stability of the locking nut 4 .

[0042] In an optional embodiment, a first avoidance hole 12 is provided on the base 1 , and the projection of the locking nut 4 on the base 1 falls on an area outside the first avoidance hole 12 .

[0043] When it is needed to lock components such as faucets 6, a water pipe needs to pass through the middle of the locking device to achieve water conduction, so a first avoidance hole 12 is provided for the passage of structures such as water pipes.

[0044] In an optional embodiment, a sealing groove is provided on one side of the base 1 close to the locking nut 4, a sealing gasket 5 is provided in the sealing groove, and a first through hole, a second through hole and a third through hole are respectively provided on the sealing gasket 5 at positions corresponding to the first avoidance hole 12, the first locking hole 11 and the first screw hole 10.

[0045] The presence of the sealing groove and the sealing gasket 5 can improve the sealing effect and prevent water or liquid on the table top 7 from flowing under the table top 7. At the same time, in order to allow the passage of similar structures such as water pipes, as well as the passage of the screw 2 and the locking rod 3, the first through hole, the second through hole and the third through hole are set.

[0046] In an optional embodiment, the projection of the locking nut 4 on the base 1 partially falls on the base 1 and partially falls outside the base 1 .

[0047] The projection of the locking nut 4 on the base 1 partially falls on the base 1 and partially falls outside the base 1, which is beneficial to increase the contact area between the locking nut 4 and the part to be locked, thereby improving the stability of the locking device. At the same time, due to the increase in the distance between the locking nut 4 and the axis of the screw 2, under the same torque condition, the force on the positioning tooth 43 can be reduced, further improving the stability of the locking device.

[0048] In an optional embodiment, a mounting platform 13 is provided on a side of the base 1 away from the locking nut 4 .

[0049] The mounting platform 13 facilitates the assembly of other components such as the faucet 6. Specifically, in order to facilitate assembly, a conical surface, a thread, a bayonet or other connecting structures can be provided on the mounting platform 13, which can be selected according to needs.

[0050] In an optional embodiment, the locking nut positioning portion 42 includes an arcuate surface located at the edge of the locking nut 4 , the radius of the arcuate surface is equal to the radius of the first locking hole 11 , and the curvature of the arcuate surface is greater than 120°.

[0051] The locking nut positioning portion 42 is provided with an arc surface. Compared with a round hole, on the one hand, the arc surface is conducive to reducing the material used for the locking nut 4, thereby helping to reduce costs; on the other hand, the round hole requires the screw 2 to be accurately aligned with the round hole before it can pass through. In comparison, the arc surface greatly reduces the difficulty of alignment, which is conducive to improving the efficiency of disassembly and assembly. Especially in the working conditions such as installing a faucet 6, the locking nut 4 is located on the other side of the table 7, and the alignment is more difficult. At this time, the provision of the arc surface is particularly important for improving the installation efficiency.

[0052] Specifically, in order to maintain the stability of the cooperation between the locking nut positioning portion 42 and the locking rod 3, the curvature of the locking nut positioning portion 42 should not be too small, and usually needs to be greater than 120°, preferably 180°-270°.

[0053] Second embodiment

[0054] Please refer to Figure 4 This embodiment provides another embodiment of the utility model to provide a water outlet assembly, including a faucet 6 and a countertop 7, and the faucet 6 is installed on the countertop 7 by the locking device described in any one of the aforementioned embodiments.

[0055] The locking device of the utility model is used in the installation of the faucet 6 and can be assembled from above the table 7, thereby improving the convenience of installation.

[0056] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
