Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a fixing device and a faucet. Background Art

[0002] In the prior art, a faucet is fixed on a tabletop through a fixing device. Among them, the on-table installation type fixing device usually includes a fixing base, a screw rod and a clamping block. The screw rod passes through the fixing base and is connected to the clamping block below. During installation, the fixing base is arranged in an installation hole on the tabletop, and the screw rod is rotated to move the clamping block below the tabletop upward until the clamping block abuts against the bottom of the tabletop.

[0003] Although this on-table installation type fixing device can avoid the inconvenience of installation caused by limited space and low visibility below the tabletop, for a faucet product with a pull-out pipe, in order to prevent the pull-out pipe from interfering with the static pipe when being pulled, it is necessary to separate the pull-out pipe from the static pipe (i.e., the pipe that remains fixed during use), and the through holes on the fixing base for the pipe to pass through need to be correspondingly separated. Since the end of the pipe far from the faucet usually has a relatively thick connecting component with an outer diameter, the inner diameter of the separated through hole is insufficient, and it is difficult to insert the end of the pipe with the connecting component from above the separated through hole under the tabletop. The operator needs to insert the pipe from below the through hole under the tabletop to above the tabletop, and the installation difficulty is great. Summary of the Utility Model

[0004] The purpose of the embodiment of the utility model is to provide a fixing device and a faucet with simple structure and convenient and fast installation in view of the existing technical situation.

[0005] To achieve the above purpose, the embodiment of the utility model adopts the following technical scheme:

[0006] First of all, the embodiment of the utility model provides a fixing device, including a base and a clamping assembly. The base is provided with a main through hole. The clamping assembly includes a clamping block arranged below the base and an adjusting member for driving the clamping block to move in a direction close to or away from the base. The adjusting member is connected to the base and is arranged beside the main through hole.

[0007] The base is connected with a separating member. The separating member includes a main body. The main body is arranged in the main through hole and divides the main through hole into at least two sub-cavities for accommodating pipes. An elastic part is arranged on the outer side wall of the main body.

[0008] The adjusting member is provided with a limiting part located above the elastic part. The positive projection of the limiting part and the elastic part at least partially coincides in the up-down direction. The bottom surface of the limiting part forms a limiting end surface for pressing and fixing the elastic part.

[0009] In some embodiments, the elastic part abuts against the inner side wall of the main through hole, the limiting part is arranged above the main through hole, and at least part of the positive projection of the limiting end face and the main through hole in the up-down direction coincides.

[0010] In some embodiments, the elastic part abuts against the inner side wall of the main through hole, at least part of the positive projection of the limiting end face and the elastic part in the up-down direction coincides, and at least part of the positive projection of the limiting end face and the main through hole in the up-down direction coincides.

[0011] In some embodiments, the elastic part includes a connecting end, the connecting end is connected to the outer side wall of the main body, and the connecting end is bent upward to form a deformed end.

[0012] In some embodiments, the adjusting part includes a head and a rod body arranged in sequence from top to bottom, the head extends outward in the radial direction to form the limiting part, and the rod body penetrates through the base and is connected to the clamping block.

[0013] In some embodiments, the main body includes a main tube body, the main tube body is provided with a first sub-cavity, the outer side wall of the main tube body extends outward to form a first partition and a second partition, and a second sub-cavity is formed between the first partition and the second partition.

[0014] In some embodiments, the main tube body is further provided with a guiding groove for guiding the moving direction of the clamping block, the guiding groove is arranged along the axial direction of the adjusting part, and the guiding groove is arranged on one side of the first partition and / or the second partition facing away from the second sub-cavity.

[0015] In some embodiments, the lower ends of the first partition and the second partition are provided with guiding inclined surfaces for driving the clamping block to rotate along the second sub-cavity towards the direction of the guiding groove, the guiding inclined surfaces incline upward along the direction away from the main tube body, the clamping block includes a connecting part and a clamping part connected to each other, the connecting part is connected to the adjusting part, and one end of the clamping part facing the clamping part is provided with a guiding slope surface for movably abutting against the guiding inclined surface.

[0016] In some embodiments, the elastic part is arranged at the upper end of the guiding groove.

[0017] In some embodiments, the upper end opening of the main through hole where the main body extends out is turned outwards and folded to form a limiting folded edge.

[0018] Secondly, the embodiment of the present utility model further provides a faucet, including the above-mentioned fixing device.

[0019] The beneficial effects of the embodiment of the present utility model are as follows:

[0020] On the one hand, this fixing device can fix the base from above the tabletop through the clamping block and the adjusting part. On the other hand, through the relatively independent and detachable partition and base, while ensuring that the pull-out pipe and the static pipe of the faucet can be separated, it enables each pipe of the faucet, even with relatively thick connecting parts with an outer diameter, to easily pass through the main through-hole of the base from above the installation hole of the tabletop to below the tabletop. Thus, the fixing of the base and the operation of passing the pipes through the tabletop can both be completed on the tabletop, making the overall installation of the fixing device more convenient and fast. At the same time, by making full use of the adjusting part and setting a limiting part on the adjusting part, at least part of the orthographic projection of the limiting part and the elastic part in the up-and-down direction coincides. Through the cooperation of the limiting end face of the limiting part and the elastic part of the partition, the partition is pressed and fixed. When the pull-out pipe is pulled, the partition is not easily affected by the pulling force when the pull-out pipe is pulled and separated from the base. At the same time, there is no need to specially design a clamping platform on the base, effectively reducing the processing difficulty of the product, and there is no need to additionally set parts for clamping the partition, making the overall structure of the fixing device simpler and more compact. In addition, this fixing device can be applied to both pull-out faucet products and conventional faucet products. When the pipes do not need to be separated, only the partition needs to be taken out, making the device more versatile. Description of the Drawings

[0031] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "one side", "one end", "bottom", "outer", "inner", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the structure referred to has a specific orientation, is constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0032] The present utility model will be further described below with reference to the drawings and embodiments:

[0033] Embodiment 1

[0034] Refer to Figures 1 to 3 and Figure 6 As shown, this embodiment discloses a fixing device, including a base 1 and a clamping assembly 2. The base 1 is provided with a main through hole 11. The clamping assembly 2 includes a clamping block 22 disposed below the base 1 and an adjusting member 21 for driving the clamping block 22 to move in a direction close to or away from the base 1. The adjusting member 21 is connected to the base 1 and is disposed beside the main through hole 11. Among them, the adjusting member 21 can be a rotary adjusting member 21. Exemplarily, the adjusting member 21 can be a screw.

[0035] The base 1 is connected with a separating member 3. The separating member 3 includes a main body 31. The main body 31 is disposed in the main through hole 11 and divides the main through hole 11 into at least two sub-cavities for accommodating pipes. The outer side wall of the main body 31 is provided with an elastic portion 32.

[0036] The adjusting member 21 is provided with a limiting portion 211 located above the elastic portion 32. The positive projection of the limiting portion 211 and the elastic portion 32 in the up-down direction at least partially overlaps. The bottom surface of the limiting portion 211 forms a limiting end surface 212 for pressing and fixing the elastic portion 32. In this embodiment, two sets of elastic portions 32 and clamping assemblies 2 are respectively provided.

[0037] In this embodiment, the separating member 3 and the base 1 are detachably arranged. The separating member 3 is provided with an elastic portion 32. During installation, first assemble the clamping assembly 2 onto the base 1, and then insert the base 1 with the clamping assembly 2 into the installation hole on the tabletop. Operate the adjusting member 21 to drive the clamping block 22 to approach the base 1 until the clamping block 22 tightly abuts against the bottom surface of the tabletop. Then, refer to Figure 7As shown, each pipeline of the faucet can be inserted from above the mounting hole on the tabletop through the main through-hole 11 of the base 1 to below the tabletop. Since the partition member 3 has not been installed at this time, the inner diameter of the main through-hole 11 is large enough, and each pipeline can easily be inserted from above the mounting hole on the tabletop through the main through-hole 11 of the base 1 to below the tabletop even with relatively thick connecting components on the outer diameter. Subsequently, the pipelines to be separated are separated into different sub-cavities by the partition member 3, and then the partition member 3 is inserted downward into the main through-hole 11 from above the base 1. Since at least part of the orthographic projection of the limiting portion 211 and the elastic portion 32 in the vertical direction overlaps, when the elastic portion 32 reaches the position where the limiting portion 211 is located, the elastic portion 32 is abutted by the limiting portion 211 and deforms. As the partition member 3 moves downward, the elastic portion 32 moves below the limiting portion 211, and the elastic portion 32 returns to its original shape. The partition member 3 reaches the installation position. At this time, at least part of the limiting end surface 212 is located directly above the elastic portion 32. The limiting end surface 212 can limit the upward movement stroke of the partition member 3 and prevent the partition member 3 from being separated from the base 1 under the influence of the pulling force when the pull-out pipeline 41 is pulled. Thus, during the use of the faucet, when the pull-out pipeline 41 is pulled, the partition member 3 is not easily affected by the pulling force when the pull-out pipeline 41 is pulled and separated from the base 1 under the cooperation of the elastic portion 32 and the limiting end surface 212.

[0038] On the one hand, in this embodiment, the base 1 can be fixed from above the tabletop through the clamping block 22 and the adjusting member 21. On the other hand, through the relatively independent and detachable partition member 3 and the base 1, while ensuring that the pull-out pipeline 41 and the static pipeline 42 of the faucet can be separated, each pipeline of the faucet can easily be inserted from above the mounting hole on the tabletop through the main through-hole 11 of the base 1 to below the tabletop even with relatively thick connecting components on the outer diameter. Thus, the fixing of the base 1 and the operation of the pipeline passing through the tabletop can be completed on the tabletop, and the overall installation of the fixing device is more convenient and fast. At the same time, by making full use of the adjusting member 21 and providing a limiting portion 211 on the adjusting member 21, at least part of the orthographic projection of the limiting portion 211 and the elastic portion 32 in the vertical direction overlaps. Through the cooperation of the limiting end surface 212 of the limiting portion 211 and the elastic portion 32 of the partition member 3, the partition member 3 is pressed and fixed. When the pull-out pipeline 41 is pulled, the partition member 3 is not easily affected by the pulling force when the pull-out pipeline 41 is pulled and separated from the base 1 under the cooperation of the elastic portion 32 and the limiting end surface 212. At the same time, there is no need to specially design a clamping table on the base 1, effectively reducing the processing difficulty of the product, and there is no need to additionally provide components for clamping the partition member 3. The overall structure of the fixing device is simpler and more compact. In addition, this fixing device can be applied to both pull-out faucet products and conventional faucet products. When the pipelines do not need to be separated, only the partition member 3 needs to be taken out, and the versatility of the device is stronger.

[0039] It should be noted that referring to Figure 4 and Figure 6As shown, the partition 3 can divide the main through hole 11 into at least two sub-cavities. The number of sub-cavities can be two. For example, the pull-out pipe 41 is independently inserted into one sub-cavity (the first sub-cavity 331), and the remaining static pipes 42 are inserted into another sub-cavity (the second sub-cavity 332). It can also be more than two, for example, three or four, but not limited to this.

[0040] The elastic portion 32 abuts against the inner wall of the main through hole 11 , the limiting portion 211 is disposed above the main through hole 11 , and the orthographic projections of the limiting end surface 212 and the main through hole 11 in the up and down directions at least partially overlap.

[0041] The elastic portion 32 abuts against the inner wall of the main through hole 11, thereby enabling the partition 3 to be fixed in the main through hole 11. During the use of the pull-out faucet, when the pull-out pipe 41 is pulled, if the pulling force is too great and causes the partition 3 to move up, the elastic portion 32 is blocked by the upper limiting end surface 212 to ensure that the partition 3 does not move up any more and ensures that the partition 3 is not easily separated from the base 1.

[0042] There is no need to specially design a buckling platform on the base 1, which effectively reduces the difficulty of product processing. There is no need to set up additional parts for buckling the separator 3, and the overall structure of the fixing device is simpler and more compact.

[0043] Among them, see Figure 3 As shown, the elastic portion 32 includes a connecting end, which is connected to the outer side wall of the main body 31 and is bent upward to form a deformation end.

[0044] By setting the upwardly bent deformation end, when the separator 3 is installed downwardly into the main through hole 11 of the base 1, the elastic part 32 can overcome the obstruction of the limiting part 211 with a relatively small force and be smoothly installed into the main through hole 11 of the base 1. After the separator 3 is installed, the elastic part 32 needs a relatively large force to deform and break away from the obstruction of the limiting part 211, thereby achieving the effect that the separator 3 is easy to install and not easy to separate from the base 1.

[0045] Among them, see Figures 2 to 4 As shown, the adjusting member 21 includes a head and a shaft arranged in sequence from top to bottom. The head extends outwardly in a radial direction to form a limiting portion 211 , and the shaft penetrates the base 1 and is connected to the clamping block 22 .

[0046] The pressing structure of the separator 3 is simple to set up, and there is no need to specially design a pressing platform on the base 1, which effectively reduces the difficulty of product processing. There is no need to set up additional parts for pressing the separator 3, and the overall structure of the fixing device is simpler and more compact.

[0047] Among them, see Figure 2 , Figure 4 , Figure 5 and Figure 8As shown, the main body 31 includes a main pipe body 311. The main pipe body 311 is provided with a first sub-cavity 331. The outer side wall of the main pipe body 311 extends outward to form a first partition 312 and a second partition 313. A second sub-cavity 332 is formed between the first partition 312 and the second partition 313.

[0048] In this embodiment, the first sub-cavity 331 can accommodate the draw pipe 41, and the second sub-cavity 332 can accommodate the remaining static pipes 42 except the draw pipe 41.

[0049] Among them, referring to Figure 4 and Figure 6 As shown, the main body 31 extends out of the upper opening of the main through-hole 11 and is turned outward to form a limiting flange 34. By providing the limiting flange 34, the downward movement stroke of the separator 3 relative to the base 1 is limited, preventing the fixing effect of the elastic part 32 of the separator 3 from failing due to excessive downward pulling force when the draw pipe 41 resets and moves downward, and separating from below the main through-hole 11.

[0050] Among them, referring to Figures 4 to 6 As shown, the main pipe body 311 is also provided with a guide groove 35 for guiding the moving direction of the clamping block 22. The guide groove 35 is arranged along the axial direction of the adjusting member 21. The guide groove 35 is arranged on one side of the first partition 312 and / or the second partition 313 facing away from the second sub-cavity 332. In this embodiment, there are two groups of guide grooves 35, which are respectively arranged on one side of the first partition 312 and the second partition 313 facing away from the second sub-cavity 332. The connection line of the two groups of guide grooves 35 passes through the axis of the mounting hole on the table surface, which is beneficial to improving the fixing firmness of the base 1.

[0051] Among them, referring to Figure 6 As shown, the elastic part 32 is arranged at the upper end of the guide groove 35, and the structure of the separator 3 is more compact.

[0052] Secondly, this embodiment also discloses a faucet, including the above-mentioned fixing device.

[0053] Embodiment 2

[0054] The difference between this embodiment and Embodiment 1 is that, referring to Figures 9 to 10 As shown, the lower ends of the first partition 312 and the second partition 313 are provided with guide inclined surfaces 36 for driving the clamping block 22 to rotate along the second sub-cavity 332 towards the guide groove 35. The guide inclined surfaces 36 are inclined upward along the direction away from the main pipe body 311. The clamping block 22 includes a connecting part 221 and a clamping part 222 which are connected to each other. The connecting part 221 is connected to the adjusting member 21. One end of the clamping part 222 facing the clamping part 222 is provided with a guide slope 223 for movably abutting against the guide inclined surface 36.

[0055] By providing the guiding slope 36 , the separator 3 can not only have the basic pipeline separation function, but also have the function of assisting the installation of the base 1 .

[0056] During installation, first assemble the clamping assembly 2 to the base 1, the rod of the adjusting member 21 passes through the base 1 and is connected to the clamping block 22 under the base 1, rotate the clamping block 22 to be directly below the main through hole 11, and then insert the base 1 with the clamping assembly 2 into the mounting hole of the table top, and then insert the partition 3, as the partition 3 moves downward, the guide slope 36 on the partition 3 moves downward toward the clamping block 22 and abuts against the guide slope 223 of the clamping block 22, and then as the guide slope 36 moves downward, the guide slope 36 pushes the guide slope 223 to rotate outward along the second sub-chamber 332 toward the direction of the guide groove 35, and then the clamping block 22 moves in the vertical direction to the outside of the mounting hole of the table top, and then the adjusting member 21 can be rotated to drive the clamping block 22 close to the base 1 until the clamping block 22 is tightly against the bottom surface of the table top, so that the base 1 can be quickly fixed with the assistance of the partition 3.

[0057] In addition, the relative distance between the guiding slope 36 of the adjusting member 21 and the elastic portion 32 can be set so that after the clamping block 22 rotates outward to the location of the guiding groove 35 , the elastic portion 32 is still above the limiting portion 211 or just abuts against the upper end of the limiting portion 211 .

[0058] Therefore, after the base 1 is fixed, due to the action of the elastic part 32 and the limiting part 211, the separator 3 is not firmly fixed in the main through hole 11, and the separator 3 can be easily taken out, so that the various pipes of the faucet can be plugged from the main through hole 11 of the base 1 from above the mounting hole of the countertop to below the countertop, and then the separator 3 is inserted into the main through hole 11 until the elastic part 32 overcomes the obstruction of the limiting part 211 and moves to below the limiting end face 212, and abuts against the inner wall of the main through hole 11, so that the separator 3 is firmly fixed on the base 1.

[0059] Of course, the above illustrations are only preferred implementation modes of the present invention, and are not intended to limit the scope of use of the present invention. Therefore, any equivalent changes made to the principles of the present invention should be included in the protection scope of the present invention.
