DETAILED DESCRIPTION

[0016] To further illustrate each embodiment, this utility model is accompanied by drawings. These drawings form part of the disclosed content of this utility model and are primarily used to explain the embodiments, thus allowing the functional principle of the embodiments to be explained in conjunction with the relevant description. With reference to this content, a person skilled in the art should be able to understand other possible embodiments as well as the advantages of this utility model. The components in the drawings are not drawn to scale, and similar component symbols are frequently used to denote similar components.

[0017] The present utility model is explained in more detail below with reference to the drawings and specific embodiments. Example 1

[0018] According to the present embodiment, a mounting structure 100 for a tap is provided for mounting on a plate with mounting holes on a washbasin or countertop basin, comprising a mounting seat 1, a sleeve 2, a bolt 3, a mounting claw 4, a waste protection cap 5 and a sealing ring 6, wherein the mounting seat 1 is adapted to be mounted above the plate and used for mounting and connecting to a tap, wherein the sleeve 2 is designed to penetrate and is mounted in the mounting hole of the plate, with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 to Fig. 10.

[0019] Furthermore, it is provided that the mounting seat 1 comprises an annular body 11, wherein the annular body 11 has a body channel 12, wherein the body channel 12 can be used to guide structures such as the tap connection hose and the water inlet nut, wherein the annular body 11 has a circumferentially extending body side wall 112, wherein the lower part of the body side wall 112 is provided with a locking structure 111, with reference to Fig. 1, Fig. 2 to Fig. 3.

[0020] Furthermore, the sleeve 2 is provided to have a sleeve body 21, wherein the sleeve body 21 is a hollow cylindrical structure extending in the axial direction, with the mounting seat 1 assembling with the sleeve 2. In the present embodiment, the shape of the sleeve body 21 is designed to be inserted into the body channel 12 of the annular body 11 in the axial direction. It is further provided that a limiting flange 25 is arranged at the upper end of the sleeve body 21, wherein the limiting flange 25 is positioned and mounted on the upper end face of the mounting seat 1, so that the sleeve 2 is positioned and mounted on the mounting seat 1 via the limiting flange 25.The diameter of the lower part of the sleeve body 21 is smaller than the mounting hole of the washbasin or countertop basin, allowing the lower part of the sleeve 2 to pass through the mounting hole and under the table. The sleeve 2 can be used to guide and limit the installation of the mounting seat 1 relative to the mounting hole of the washbasin or countertop basin. The section of the sleeve body 21 is C-shaped overall and has a lateral opening 26. After the water supply pipe at the faucet is inserted from the table, through the channel 12 in the center of the mounting seat 1, and under the table, the pipe body of the water supply pipe can then be guided through the lateral opening 26 to install the sleeve 2.This means that the sleeve 2 can be mounted after the water passage pipe, allowing the larger water passage pipe and the connection to pass through the body channel 12 of the mounting seat 1. Furthermore, the sleeve channel 27 in the center of the sleeve body 21 can also be used to accommodate components such as the faucet connection hose and the water inlet nut.

[0021] Furthermore, the mounting seat 1 is provided with two bolt holes 13, the bolt hole 13 being located on the side wall 112 of the annular body 11. In the present embodiment, a section of the side wall 112 projects into the body channel 12 to form a projecting section 113, with the bolt hole 13 being located in the projecting section 113, as shown in Fig. Figure 3 shows the bolt hole 13 extending axially through the mounting seat 1. The bolt hole 13 serves to insert the bolt 3. The bolt 3 is rotatably mounted in the bolt hole 13. Furthermore, the sleeve body 21 has a side wall 211, with an axially extending guide groove 22 arranged concavely on the side wall 211. The shape and position of the guide groove 22 are adapted to the preceding section 113, so that the sleeve 2 can be mounted in the body channel 12 in the center of the mounting seat 1 by means of the interacting design of the guide groove 22 with the preceding section 113. In the present embodiment, two guide grooves 22 are provided.

[0022] The bolt 3 penetrates the mounting seat 1 via the bolt hole 13 and engages in a guide groove 22 of the sleeve 2. The head of the bolt 3 rests against the mounting seat 1. Furthermore, the mounting claw 4 is screwed to the bolt 3, the mounting claw 4 being provided with an internal threaded bore 41, and the bolt 3 being screwed to the mounting claw 4 via this internal threaded bore 41. The mounting claws 4 can be moved along with the bolt 3, or the mounting claws 4 can be limited by the sleeve 2 to move up and down around the screw section of the bolt 3.In the present embodiment, the sleeve 2 is provided with a limiting column 23 on one side of the guide groove 22, wherein the limiting column 23 is arranged extending in the axial direction, wherein the mounting claws 4 can be limited by the limiting column 23 in order to move up and down around the screw section of the bolt 3, wherein the guide groove 22 can serve to guide the up and down movement of the mounting claw 4.

[0023] The mounting claw 4 can be pivoted into the receiving position, with reference to Fig. 8. In this mounting position, the mounting claw 4 is essentially received inside the sleeve 2. This allows the lower part of the sleeve 2 and the mounting claw 4 to be smoothly inserted through the mounting hole of the washbasin or countertop basin in this received state. The mounting claw 3 can also be pivoted in the other direction into the open position, with reference to Fig. 5. In this open position, the mounting claws 4 protrude from the sleeve 2. The mounting claw 4 can be moved upwards by the limiting column 23 around the screw section of the bolt 3 until it rests against the lower surface of the plate contacting the sink or countertop basin, so that the mounting claw 4 and the mounting seat 1 are clamped firmly on both sides of the plate. The mounting structure 100 for a faucet is attached and mounted on the countertop of the sink or countertop basin, thus enabling quick and convenient installation.

[0024] Furthermore, it is provided that at least one elastic structure 24 is arranged on the side wall 211 of the sleeve body of the sleeve 2, wherein the elastic structure 24 is intended to rest against the inner wall of the mounting hole of the washbasin or countertop basin, so that the sleeve 2 can adapt to different mounting hole sizes, thereby making installation more convenient, with reference to Fig. 1, Fig. 2, Fig. 3 to Fig. 4.

[0025] Furthermore, the elastic structure 24 is arranged on one side of the side wall 211 of the sleeve body of the sleeve 2, facing the bolt 3, so that the sleeve 2 is pre-tensioned within the mounting hole towards one side of the bolt 3. When the sleeve 2 is installed in the mounting hole of the sink or countertop basin, the side of the guide groove 22 of the sleeve 2 is brought closer to the edge of the mounting hole due to the recoil of the elastic structure 24. This increases the contact area of ​​the mounting claw 4 with the base wall around the mounting hole, thus making the installation of the mounting structure 100 for a faucet more stable and preventing the faucet from being easily loosened.In the present embodiment, it is provided that two elastic structures 24 are arranged on the side wall 211 of the sleeve body of the sleeve 2, wherein the two elastic structures 24 are arranged on the side of the side wall 211 of the sleeve body opposite the two guide grooves 22.

[0026] Preferably, the elastic structure 24 is designed as a self-supporting structure with a downward-facing fixed end 241 and an upward-facing free end 242, with reference to Fig. 4. In the present embodiment, a receiving slot 15 with an elastic structure is arranged at the lower end of the mounting seat 1, wherein the free end 242 of the elastic structure 24 lies partially within the receiving slot 15, furthermore with reference to Fig. 5, Fig. 6 and Fig. 8. This prevents the free end 242 of the elastic structure 24 from being lower than the underside of the tabletop when it abuts a mounting structure such as a thin-walled sink or a thin-walled countertop basin, which would cause the free end 242 of the elastic structure 24 to become wedged under the mounting hole, making the mounting structure difficult to disassemble. Fig. Figure 5 shows that the two elastic structures 24 can, but are not limited to, sharing a circumferentially extending receiving slot 15. In other embodiments, each elastic structure 24 can also be provided with a separate receiving slot. Furthermore, it is provided that the lower end of the limiting column 23 extends downwards beyond the sleeve body 21, i.e., the lower end of the limiting column 23 is lower than the lower end of the sleeve body 21, with reference to Fig. 4. The lower ends of the two are offset vertically, allowing the mounting claws 4 to be pivoted inwards for gripping or outwards for spreading in this offset position. The limiting column 23 can provide a rotation guide and angular limit for inward rotation for gripping and outward rotation for spreading the mounting claw 4.

[0027] A protective cap 5 is mounted at the lower end of the bolt 3. This cap serves to prevent the bolt 3 from pivoting beyond its limit position when the mounting structure 100 for a tap is disassembled, which would cause the mounting claw 4 to detach from the bolt 3. A sealing ring 6 is arranged between the lower end face of the mounting seat 1 and the table surface, thereby improving the sealing performance between the mounting structure 100 for a tap and the table surface.

[0028] Furthermore, it is provided that the upper part of the bolt hole 13 is designed as a circular hole structure 131 which is larger than the outer diameter of the screw section of the bolt 3, wherein the lower part of the bolt hole 13 is an enlarged bore structure 132 which extends towards the center of the mounting seat, with reference to Fig. 7. A natural transition can occur between the circular hole structure 131 and the enlarged bore structure 132. The head position of the bolt 3 is limited by the circular hole structure 131, thus preventing the head of the bolt 3 from shifting towards the center of the mounting seat 1 after the bolt 3 is locked, which would obstruct the passage of the water flow pipe with the nut connection through the mounting seat 1. When the mounting structure 100 for a faucet is inserted into the mounting hole of the sink, countertop basin, or the like through the enlarged bore structure 132, the mounting claw 4 can be driven by the bolt 3 to tilt towards the center of the mounting seat 1, thereby facilitating the installation of the mounting structure 100 for a faucet into the mounting hole.

[0029] Furthermore, it is provided that the assembly structure 100 for a tap further comprises an assembly correction tool 6, wherein the assembly correction tool 6 comprises a limiting section 61 and an indicator section 62, with reference to Fig. 9 to Fig. 10. In the present embodiment, the limiting section 61 is provided with a limiting hole 611, the shape of which is adapted to the outer shape of the locking structure 111 so that the assembly correction tool 6 can be oriented and encased on the locking structure 111 of the mounting seat 1. The indicator section 62 is provided with a direction indicator mark 621, 622, which serves, for example, to indicate the straight forward direction and comprises an indicator arrow 621 and an indicator text 622. The assembly correction tool 6 serves to ensure the accuracy of the assembly direction when mounting the mounting structure 100 for a faucet. When mounting the faucet after the mounting structure 100 has been completed, it ensures that the faucet is not misaligned.This prevents the need to return to the installation process and readjust the mounting structure if the faucet is found to be misaligned after installation, thus avoiding a cumbersome installation process. This improves the ease of installation.

[0030] The assembly correction tool 6 can be manufactured by punching cardboard, which makes it easy and convenient to use and operate, environmentally friendly and recyclable, and saves costs. Example 2

[0031] This embodiment differs significantly from embodiment 1 in that the mounting seat 1a with the sleeve 2a is designed differently than in embodiment 1, and that the waste protection cap 5 in embodiment 1 is replaced by a circlip 5a, which is otherwise identical to that in embodiment 1, with reference to Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17 to Fig. 18. According to the present embodiment, a mounting structure 100a for a tap is provided for mounting on a plate 300 with mounting holes 301 on a washbasin or countertop basin, comprising a mounting seat 1a, a sleeve 2a, a bolt 3, a mounting claw 4, a circlip 5a and a sealing ring 6, wherein the mounting seat 1a is adapted to be mounted above the plate 300 and to be used for mounting and connecting a tap 200, wherein the sleeve 2a is designed to penetrate and is mounted in the mounting hole 301 of the plate 300.

The diameter of the lower part of the sleeve body 21a is smaller than the mounting hole 300 of the washbasin or countertop basin, so that the lower part of the sleeve 2a can penetrate through the mounting hole 300 of the washbasin or countertop basin and under the table. Sleeve 2a can be used to guide and limit the mounting of the mounting seat 1 relative to the mounting hole 300 of the washbasin or table basin.Furthermore, the sleeve channel 27 in the center of the sleeve body 21 can also be used to accommodate components such as the faucet connection hose and the water inlet nut. A sealing ring 6 is arranged between the lower end face of the limiting flange 25a and the plate 300, thereby improving the sealing performance between the mounting structure 100a for a faucet and the plate 300.

[0034] Furthermore, it is provided that a plurality of elastic structures 24 are arranged on the side wall of the sleeve body of the sleeve 2a, wherein more than two elastic structures 24 may be provided, wherein the elastic structure 24 is intended to be placed against the inner wall of the mounting hole 300 of the washbasin or countertop basin, so that the sleeve 2a can adapt to different mounting hole sizes, thereby making installation more convenient, with reference to Fig. 11, Fig. 12, Fig. 13 to Fig. 14 as well Fig. 18.

[0035] Furthermore, it is provided that the plurality of elastic structures 24 are distributed uniformly in the circumferential direction along the side wall of the sleeve body of the sleeve 2a, or that the plurality of elastic structures 24 are distributed symmetrically relative to the center of the sleeve 2a. In the present embodiment, it is provided that three elastic structures 24 are arranged on the side wall of the sleeve body of the sleeve 2a. In the present embodiment, it is provided that the three elastic structures 24 are distributed uniformly in the circumferential direction along the side walls of the sleeve 2a, so that the sleeve 2a can be positioned in the center of the mounting hole 300 by the contact and interaction between the elastic structure 24 and the inner wall of the mounting hole 300.Therefore, the mounting structure 100a for a tap is positioned more accurately and mounted more reliably, and the sealing ring 6 can be sealed more evenly in the circumferential direction, so that the sealing effect is better.
