Description

Technical Field

[0001] The invention relates to the technical field of bathroom accessories, in particular to a weight that is adaptive to hoses with different diameters. Background Art

[0002] At present, there are two types of weights installed on the hose of pull-out faucets. One is that the weight needs to be customized according to the size of the hose, and then locked on the hose with fasteners such as bolts. The other method is to put the weight on the hose before the hose is connected.

[0003] Among them, the most direct method is to use bolts and other fasteners to connect the weight block. This method has a complex structure, and is cumbersome to install and disassemble. It is even easy for the bolts to rust after a period of use, and there is a risk that they cannot be disassembled. Alternatively, a through hole is directly designed in the middle of the weight for the hose to pass through so that the weight can be hung on the hose to achieve the corresponding function. The through-hole socket connection method is only applicable to hoses of a single specification and size, and has too many restrictions on the installation steps. If the installation is not carried out according to the steps, the user will need to reinstall the hose and the weight, which is extremely inconvenient. Summary of the invention

[0004] The invention discloses a weight that is adaptive to hoses with different diameters, aiming to improve the problems of the existing weight, such as complicated installation and disassembly and poor versatility.

[0005] The present invention adopts the following scheme:

[0007] As a further improvement, the counterweight block includes a first counterweight block and a second counterweight block, the first counterweight block and the second counterweight block are connected to each other through a connecting piece, and the first counterweight block and the second counterweight block are configured to fit together.

[0008] As a further improvement, the connecting member includes a buckle with a sliding portion arranged on the end face of any one of the counterweight blocks and a sliding groove corresponding to the other counterweight block, and the sliding groove is arranged along the rotation direction; the buckle is engaged and accommodated in the sliding groove so that the end faces of the two counterweight blocks fit each other, and when the counterweight blocks are controlled by external force to rotate relative to each other, the sliding portion corresponding to the buckle slides relative to the sliding groove.

[0009] As a further improvement, at least two of the buckles are provided and are spaced apart along a circumferential path in the direction of rotation, the two buckles are correspondingly provided in a diameter direction along the circumferential path, and each hook is correspondingly provided with a slide groove cooperating therewith.

[0010] As a further improvement, the slide groove has a first end and a second end along the rotation direction, and the first end and the second end are connected to each other; when the hose is in a semi-enclosed state, the corresponding buckle is placed at the first end, and when the hose is in a fully surrounded state, the corresponding buckle is placed at the second end.

[0011] As a further improvement, a support body is arranged between the end surfaces of the two counterweight blocks that are in contact with each other, one end of the support body is fixed to the end surface of one of the counterweight blocks, and the other end is elastically abutted against the end surface of the other counterweight block to follow the rotation of the counterweight blocks and provide a corresponding pre-tightening force after the rotation, thereby relatively tightening the two counterweight blocks.

[0012] As a further improvement, the support body is fixed on the end face of the first counterweight block, and the end face of the second counterweight block is correspondingly opened with at least one alignment hole, and the alignment hole is arranged on the rotation path of the support body; the alignment hole is adapted to the support body, and when the hose is in a fully surrounded state, one end of the corresponding support body is inserted into the alignment hole.

[0013] As a further improvement, the counterweight block is in the shape of a round cake, the two counterweight blocks are stacked on each other and can rotate relative to each other, and the hollow portion is approximately located in the middle of the counterweight block.

[0014] As a further improvement, the elastomer is an elastic sheet with a gradually varying thickness, and its thickness gradually increases along the outer peripheral direction; a mounting groove is correspondingly provided in the hollow portion of the counterweight block that clamps and accommodates the elastic sheet, and the mounting groove is formed by at least two counterweight blocks, and the elastic sheet is assembled into the mounting groove, and the cavity wall of the cavity is smoothly docked with the retaining wall of the counterweight block.

[0016] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0017] The weight hammer of the present application mutually displaces the retaining walls in the same vertical plane by rotating at least two counterweight blocks, so that the hose contained in the hollow part of the counterweight blocks is switched from a semi-enclosed state to a fully-enclosed state, thereby limiting the hose in the enclosed space formed by the dislocation of the two open hollow parts, which greatly facilitates the disassembly and assembly of the hose. In addition, the elastic body is clamped in the hollow part of at least two counterweight blocks, wherein an open cavity for accommodating an external hose is formed in the middle, and two elastic clamping parts extend from the opening of the cavity. The rotating counterweight blocks trigger the clamping parts in the hollow part through the retaining walls, so that the clamping parts are deformed in the direction of clamping the hose, thereby adapting to the assembly and fixation of hoses of various different diameters, and having high versatility and convenient operation.

[0032] Example

[0033] Combination Figures 1 to 7 This embodiment provides a weight that is adaptive to hoses of different diameters, including: a counterweight block 1 and an elastic body 2.

[0034] In this embodiment, the counterweight blocks 1 have at least two and each counterweight block 1 is formed with an open hollow portion 11, and two retaining walls 12 are formed at the opening of the hollow portion 11. The counterweight blocks 1 are connected to each other in a sliding manner so as to be relatively rotatable, so that the retaining walls 12 of different counterweight blocks 1 can be in the same vertical plane, thereby allowing an external hose to be installed into the hollow portion 11 along the opening. The elastomer 2 is clamped in the hollow part 11 of at least two counterweight blocks 1, forming a semi-enclosed C-shaped structure. An open cavity 21 for accommodating an external hose is formed in the middle of the elastomer 2, and two elastic clamping parts 22 extend from the opening of the cavity 21. By rotating at least one of the counterweight blocks 1 relative to the other counterweight block 1, the retaining walls 12 of the two counterweight blocks 1 are misaligned, and the hose placed in the cavity 21 is switched from a semi-enclosed state to a fully surrounded state, and the rotating counterweight block 1 triggers the clamping part 22 placed in the hollow part 11 through the retaining wall 12, so that the clamping part 22 is deformed in the direction of clamping the hose.

[0035] In this embodiment, by rotating at least two counterweights 1, the retaining walls 12 in the same vertical plane are mutually displaced, so that the hose contained in the hollow part 11 of the counterweight 1 is switched from a semi-enclosed state to a fully-enclosed state, thereby limiting the hose in the enclosed space formed by the dislocation of the two open hollow parts 11, which greatly facilitates the disassembly and assembly of the hose. In addition, the elastic body 2 is clamped in the hollow part 11 of at least two counterweights 1, and an open cavity 21 for accommodating an external hose is formed in the middle, and two elastic clamping parts 22 extend from the opening of the cavity 21. The rotating counterweight 1 triggers the clamping part 22 in the hollow part 11 through the retaining wall 12, so that the clamping part 22 is deformed in the direction of clamping the hose, thereby adapting to the assembly and fixation of hoses of various different diameters, with high versatility and easy operation.

[0036] See also Figure 3 and Figure 5 In one embodiment of the present invention, the counterweight 1 includes a first counterweight 1A and a second counterweight 1B. The first counterweight 1A and the second counterweight 1B are connected by a sleeve connection 3, and the first counterweight 1A and the second counterweight 1B are fitted. The counterweights 1 are rotatably and stacked with each other by the connector 3, so that the two counterweights 1 are stacked with each other and can rotate relative to each other, and the hollow parts 11 are aligned. Preferably, the counterweight 1 is in the shape of a round cake, and the hollow part 11 is approximately located in the middle of the counterweight 1, so that during the rotation of the counterweight 1, each hollow part 11 is always in the middle of the counterweight 1, and only the retaining wall 12 rotates relatively along the middle position, corresponding to gradually surrounding the hose placed in the cavity 21.

[0037] Specifically, in this embodiment, the connecting member 3 includes a buckle 31 with a sliding portion 311 disposed on the end face of any one of the counterweight blocks 1 and a slide groove 32 correspondingly opened in the other counterweight block 1, and the slide groove 32 is arranged along the rotation direction. The buckle 31 is clamped and accommodated in the slide groove 32 so that the end faces of the two counterweight blocks 1 fit each other, and when the counterweight blocks 1 are controlled by external force to rotate relatively, the slide portion 311 of the corresponding buckle 31 slides relative to the slide groove 32. Among them, the buckle 31 is arranged protruding along the end face of the counterweight block 1 and has a certain elastic deformation. When the two counterweight blocks 1 are fitted and assembled, the buckle 31 is elastically squeezed and adaptively extended to be clamped in the slide groove 32, and its slide portion 311 is tightly placed inside the slide groove 32 and can slide relatively along the opening direction of the slide groove 32, so that the counterweight block 1 can rotate relatively through the slide groove 32 when subjected to external force.

[0038] In particular, at least two buckles 31 are provided and arranged at intervals along the circumferential path of the rotation direction, and the two buckles 31 are correspondingly arranged in the diameter direction along the circumferential path, and each hook is correspondingly provided with a slide 32 cooperating therewith. In this embodiment, the slide 32 has a first end and a second end along the rotation direction, and the first end and the second end are connected to each other. When the hose is in a semi-enclosed state, the corresponding buckle 31 is placed at the first end, and when the hose is in a fully surrounded state, the corresponding buckle 31 is placed at the second end. The two buckles 31 are arranged opposite to each other to ensure the balanced rotation between the counterweights 1, and each slide 32 has a first end and a second end. The sliding part 311 of the buckle 31 slides relatively between the first end and the second end of the slide 32, thereby determining the threshold range within which each counterweight 1 can rotate, and each end can locate the position of the counterweight 1 after rotation, so as to facilitate the back and forth rotation to quickly and accurately obtain the state of the hose in the cavity 21 (semi-enclosed or fully surrounded).

[0039] Preferably, in this embodiment, a support body 4 is arranged between the end faces of the two counterweights 1 that are in contact with each other. One end of the support body 4 is fixed on the end face of one counterweight 1, and the other end thereof is elastically abutted against the end face of the other counterweight 1, so as to follow the rotation of the counterweight 1 and provide a corresponding pre-tightening force after the rotation, thereby relatively tightening the two counterweights 1. Specifically, the support body 4 is fixed on the end face of the first counterweight 1A, and the end face of the second counterweight 1B is correspondingly provided with at least one alignment hole 5, and the alignment hole 5 is arranged on the rotation path of the support body 4. The alignment hole 5 is adapted to the support body 4, so that when the support body 4 is rotated to face the alignment hole 5, one end of the support body 4 can be accommodated in the alignment hole 5, which plays a role in positioning and relative pre-tightening. When the hose is in a fully surrounded state, one end of the corresponding support body 4 is inserted into the alignment hole 5, so that the support body 4 elastically supports the two counterweights 1, and at the same time relatively positions and clamps the two counterweights 1. When the torsional force provided by the external force is greater than the abutment force of the support body 4 in the alignment hole 5 along the rotation direction, one end of the support body 4 is separated from the alignment hole 5 to elastically abut against the end face position of the counterweight block 1. In this embodiment, the support body 4 is preferably a compression spring, and one end of the compression spring is fixed on the first counterweight block 1A, and the other end is abutted against the second counterweight block 1B through the spring sleeve 6, and the spring sleeve 6 is adapted to the alignment hole 5, so that when it is rotated to face the alignment hole 5, the end of the compression spring is abutted and accommodated in the alignment hole 5 through the spring sleeve 6, and driven by the external torsional force, the spring sleeve 6 is separated from the alignment hole 5 and abutted against the end face position of the counterweight block 1. In particular, there are at least two support members, and they are arranged at intervals along the circumferential path in the rotation direction, and the two support members are correspondingly arranged in the diameter direction along the circumferential path to provide stable elastic support.

[0040] See also Figure 4 , Figure 5 and Figure 6In this embodiment, the elastic body 2 is an elastic sheet with a gradually changing thickness, and its thickness gradually increases along the outer peripheral direction. A mounting groove (not shown) is correspondingly provided in the hollow portion 11 of the counterweight block 1 that clamps and accommodates the elastic sheet. The mounting groove is formed by at least two counterweight blocks 1, and the elastic sheet is assembled into the mounting groove, and the cavity wall of the cavity 21 thereof is smoothly docked with the retaining wall 12 of the counterweight block 1. Among them, the elastic sheet is clamped and placed between at least two counterweight blocks 1, and the mounting groove corresponding to the assembly elasticity is formed by at least two counterweight blocks 1, so that the elastic sheet is assembled in the mounting groove, and the cavity wall where the cavity 21 of the elastic sheet is located is smoothly docked with the two retaining walls 12 of the counterweight. Specifically, when the rotational force of the counterweight 1 is less than the abutment force of the elastic sheet in the installation groove, the elastic sheet is still placed in the installation groove, and the rotating counterweight 1 abuts against the clamping portion 22 of the elastic sheet with a gradual thickness through its retaining wall 12, thereby triggering the clamping portion 22 to elastically deform in the direction of clamping the hose, thereby tightening the hose. When the rotational force of the counterweight 1 is greater than the abutment force of the elastic sheet in the installation groove, the elastic sheet relatively detaches from the installation groove, and the rotating counterweight 1 drives the elastic sheet to rotate relatively in the hollow part 11, thereby adjusting the clamping position of the elastic sheet on the hose, so that the elastic sheet with a gradual thickness is abutted by the retaining wall 12 in the hollow part 11, thereby triggering the clamping portion 22 to elastically deform in the direction of clamping the hose.

[0041] Preferably, a plurality of clamping protrusions 23 are provided on the side wall of the cavity 21 of the elastic sheet. The clamping protrusions 23 can make the connection between the elastic sheet and the hose tighter and achieve a better fixing effect.

[0042] The working process of the embodiment of the present invention is described in detail below:

[0043] When it is necessary to install the external hose inside the counterweight 1, the first counterweight 1A and the second counterweight 1B are rotated to face each other, so that the retaining walls 12 on different counterweights 1 are in the same vertical plane, and the openings of the corresponding hollow parts 11 are in the same direction. The external hose is assembled into the counterweight 1 along the opening of the hollow part 11 and is accommodated in the cavity 21 of the elastic body 2. At this time, the hose is in a semi-enclosed state. The user rotates the first counterweight 1A and / or the second counterweight 1B, and at least one of the counterweights 1 rotates relative to the other counterweight 1, so that the retaining walls 12 of the two counterweights 1 are misaligned, and the hose placed in the cavity 21 is switched from a semi-enclosed state to a fully enclosed state, and the hose is confined to the enclosed space formed by the misalignment of the two open hollow parts 11. And the rotating counterweight 1 triggers the clamping part 22 placed in the hollow part 11 through the retaining wall 12, so that the clamping part 22 is deformed in the direction of clamping the hose, so as to achieve the fastening of the hose in the counterweight 1. When it is necessary to remove the external hose from the inside of the counterweight block 1, the counterweight block 1 is rotated in the opposite direction so that the first counterweight block 1A and the second counterweight block 1B are rotated to face each other. At this time, the two counterweight blocks 1 are in the initial position, and the openings of their respective hollow portions 11 are located in the same direction. The two retaining walls 12 do not trigger the clamping portion 22 of the elastomer 2, thereby removing the external hose from the opening along the direction of detaching from the hollow portion 11.

[0044] It should be mentioned that the weight of the present application is also applicable to the installation method of directly inserting a hose into the weight. The external hose is directly inserted into each counterweight 1 through the hollow portion 11 of the counterweight 1, so that the weight is installed on the hose in a fixed manner, making the installation method of the weight more diverse.

[0045] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
