Description

Technical Field

[0001] The invention relates to the technical field of bathroom accessories, and in particular to a quick-detachable weight. 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 being used for a period of time, 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 realize 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 performed according to the steps, the user will need to reinstall the hose and the weight, which is extremely inconvenient. In addition, the existing weights are mostly integrated parts, which are inconvenient to disassemble and assemble and are not conducive to the assembly and tightening of the hose. Summary of the invention

[0004] The invention discloses a quick-detachable weight, aiming to improve the problem of inconvenience in assembling and disassembling the existing weight.

[0005] The present invention adopts the following scheme:

[0009] As a further improvement, a plurality of clamping blocks are provided at intervals on the outer side of the annular protrusion, and a corresponding clamping groove matching the clamping block is provided on the outer side of the counterweight block where the annular groove is located. The annular protrusion is clamped in the annular groove so that the clamping block is clamped and fixed to the corresponding clamping groove, and the clamping groove connects the annular groove with the outside, and the clamping block is partially exposed to the outside.

[0010] As a further improvement, the annular protrusion has a travel margin in the vertical direction in the annular groove, and a plurality of support members are arranged between the end faces directly opposite to the first counterweight block and the second counterweight block, and the two ends of the support members are elastically abutted against the two end faces; wherein, a plurality of guide columns are provided on the end faces of the counterweight blocks, and the support members are sleeved on the guide columns to provide a pre-tightening support force abutting against the end faces, thereby relatively fastening the two counterweight blocks.

[0011] As a further improvement, the counterweight block is in the shape of a round pancake, and the hollow portion is approximately located in the middle of the counterweight block, and the annular protrusion is arranged on the periphery of the end surface of one of the counterweight blocks.

[0012] As a further improvement, two retaining walls are formed at the opening of the hollow portion, and the two counterweight blocks are assembled facing each other, so that the retaining walls of different counterweight blocks are in the same vertical plane.

[0013] As a further improvement, two retaining walls are formed at the opening of the hollow portion, and the two counterweight blocks are assembled in a staggered manner so that the retaining walls of different counterweight blocks are in different vertical planes.

[0014] As a further improvement, the clamping member is an elastic hoop body with an opening that allows the external hose to enter and exit; the opening of the hoop body is controlled by external force to shrink or release the external force to reset, which correspondingly makes the volume of the hoop body smaller or restored.

After the hose accommodated in the cavity is relatively assembled by the two counterweight blocks, the other end of the clamping piece is clamped in the hollow part of the second counterweight block. Under the abutment of the matching surface provided in the hollow part of the second counterweight block, the clamping piece is correspondingly triggered to deform in the direction of clamping the hose, thereby clamping inward to shrink the diameter of the cavity. It is suitable for the assembly and fixation of hoses of various different diameters and has high versatility. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example

[0031] Combination Figures 1 to 3 This embodiment provides a quick-release weight, including: a counterweight block 1 and a clamping member 2.

[0032] In this embodiment, the counterweight 1 includes a first counterweight 1A and a second counterweight 1B connected in a quick-release manner, and the two counterweights 1 are arranged relative to each other. The first counterweight 1A and the second counterweight 1B are both formed with an open hollow portion 11, and the hollow portions 11 are arranged in alignment with each other. Among them, the clamping member 2 is a semi-enclosed C-shaped structure, and an open cavity 21 for accommodating an external hose is formed in the middle of the clamping member 2, and the clamping member 2 is controlled by an external force to clamp inward, correspondingly controlling the size of the cavity 21. One end of the clamping piece 2 is detachably clamped and fixed to the first counterweight block 1A so that the opening of the cavity 21 is opposite to the opening of the first counterweight block 1A, thereby installing the external hose into the cavity 21 along the two openings, and the other end is clamped and placed in the hollow portion 11 of the second counterweight block 1B after the two counterweight blocks 1 are assembled, and the hollow portion 11 is provided with a mating surface 12 corresponding to the clamping piece 2, and the mating surface 12 can trigger the clamping piece 2 to deform in the direction of the clamping hose.

[0033] In this embodiment, the first counterweight 1A and the second counterweight 1B can be quickly assembled and disassembled through the quick release fit, and one end of the clamping member 2 is detachably clamped and fixed to the first counterweight 1A, and the other end is clamped and placed in the hollow part 11 of the second counterweight 1B after assembly, thereby clamping the hose placed in the hollow part 11 inwardly, realizing convenient and fast hose assembly and fixation. Among them, the opening of the cavity 21 where the clamping member 2 is located is directly opposite to the opening of the hollow part 11 where the first counterweight 1A is located, so that the interior is exposed in the same direction, so that the external hose can be assembled into the cavity 21 of the clamping member 2 through the opening of the cavity 21 to the opening of the first counterweight 1A, which is convenient for users to operate and use. After the hose contained in the cavity 21 is relatively assembled through the two counterweight blocks 1, the other end of the clamping piece 2 is clamped and placed in the hollow part 11 of the second counterweight block 1B. Under the abutment of the matching surface 12 provided in the hollow part 11 of the second counterweight block 1B, the clamping piece 2 is correspondingly triggered to deform in the direction of clamping the hose, thereby clamping inward to shrink the diameter of the cavity 21. It is suitable for the assembly and fixation of hoses of various different diameters and has high versatility.

[0034] See also Figure 3 and Figure 4 The first counterweight 1A and the second counterweight 1B are connected by a disassembly member 3, and the two counterweights 1 are stacked on each other in an up-and-down configuration, and the end faces of the first counterweight 1A and the second counterweight 1B are opposite to each other. Specifically, the disassembly member 3 includes an annular protrusion 31 provided on the end face of one of the counterweights 1 and an annular groove 32 provided on the other counterweight 1 and adapted to the annular protrusion 31. The annular protrusion 31 is in the shape of an elastic sheet and has a notch that avoids the opening of the hollow portion 11. The annular protrusion 31 is clamped in the annular groove 32 to assemble and fix the first counterweight 1A and the second counterweight 1B. Among them, a plurality of blocks 311 are arranged at intervals on the outer side of the annular protrusion 31, and a groove 321 matching with the block 311 is correspondingly opened on the outer side of the counterweight block 1 where the annular groove 32 is located, and the block 311 is clamped in the annular groove 32 through the annular protrusion 31, so that the block 311 is clamped and fixed to the corresponding groove 321. The groove 321 connects the annular groove 32 with the outside, and the block 311 is partially exposed to the outside. The first counterweight block 1A is assembled into the annular groove 32 of the second counterweight block 1B through the annular protrusion 31, and the block 311 arranged on the outer side of the annular protrusion 31 is elastically clamped with the corresponding groove 321, so that the assembly of the first counterweight block 1A and the second counterweight block 1B is more stable. The card slot 321 is correspondingly opened on the outer side surface of the second counterweight block 1B, correspondingly connecting the outside and the annular groove 32. The card block 311 is at least partially exposed to the outside, so that it is convenient for the user to directly press the card block 311 inward to disengage the card block 311 from the card slot 321, thereby releasing the clamping limit between the annular protrusion 31 and the annular groove 32, and being able to quickly detach the first counterweight block 1A and the second counterweight block 1B.

[0035] In particular, the counterweight 1 is in the shape of a round pancake and the two counterweights 1 have approximately the same size, and the hollow portion 11 is approximately located in the middle of the counterweight 1, so that the two counterweights 1 can accommodate the clamping member 2 through the hollow portions 11 that are arranged opposite to each other. Among them, the annular protrusion 31 is arranged around the periphery of the end surface of one of the counterweights 1 and the two are an integrally formed structure, and the annular groove 32 is correspondingly opened at the relative position of the other counterweight 1 to achieve an inserted clamping fit.

[0036] In one embodiment of the present invention, the annular protrusion 31 has a travel margin in the vertical direction in the annular groove 32, which can allow the annular protrusion 31 to move relative to the annular groove 32 in the vertical direction. A plurality of support members 4 are arranged between the end faces of the first counterweight block 1A and the second counterweight block 1B, and the two ends of the support members 4 elastically abut on the two end faces, so that the two counterweight blocks 1 elastically abut against each other, and when the external force presses the counterweight blocks 1 toward each other in the vertical direction, the two counterweight blocks 1 move relatively elastically within the travel margin. Preferably, the support member 4 is a compression spring, and the plurality of compression springs are evenly spaced between the two end faces in the circumferential direction to provide stable elastic support. Among them, a plurality of guide columns 13 are correspondingly arranged on the end faces of the counterweight block 1, and each support member 4 is sleeved between one of the guide columns 13 to provide a pre-tightening support force abutting against the end face, thereby relatively elastically fastening the two counterweight blocks 1.

[0037] In this embodiment, two retaining walls 14 are formed at the opening of the hollow part 11. The two counterweights 1 are assembled facing each other, so that the retaining walls 14 of different counterweights 1 are in the same vertical plane. The two counterweights 1 assembled facing each other make their retaining walls 14 in the same vertical plane, and the openings of the clamping members 2 placed in the two hollow parts 11 are facing the openings of the second counterweight 1B, so that the interior is exposed in the same direction, which is convenient for the external hose to be directly withdrawn along the directions of each opening to the outside of the cavity 21 of the clamping member 2. In addition, at this time, the opening of the clamping member 2 is subjected to less squeezing force from the second counterweight 1B (because the two openings are facing each other, the opening of the clamping member 2 is subjected to less abutment contact with the second counterweight 1B), which is suitable for the assembly and tightening of external hoses with larger diameters.

[0038] In another embodiment, the two counterweights 1 are assembled in a mutually offset manner, so that the retaining walls 14 of different counterweights 1 are located in different vertical planes. The two counterweights 1 are assembled in a mutually offset manner so that the retaining walls 14 of each are located in different vertical planes, and the openings of the clamping members 2 placed in the two hollow portions 11 are arranged in an offset manner with the openings of the second counterweight 1B. The second counterweight 1B is relatively hidden inside the cavity 21 of the clamping member 2, so that the clamping member 2 is completely placed in the two counterweights 1 along the side direction under the cooperation of the first counterweight 1A and the second counterweight 1B. In addition, at this time, the opening of the clamping member 2 is subjected to a greater extrusion force from the second counterweight 1B (due to the offset of the two openings, the opening of the clamping member 2 is subjected to more abutment contact from the second counterweight 1B), which is suitable for the assembly and tightening of external hoses with smaller diameters.

[0039] See also Figure 2 , Figure 3 and Figure 5 Preferably, the clamping member 2 is an elastic hoop body with an opening that allows the external hose to enter and exit. The opening of the hoop body is controlled by an external force to shrink or release the external force to reset, correspondingly making the cavity 21 of the hoop body smaller or restored.

[0040] Specifically, the hoop body includes a mounting portion 22 and a claw portion 23 disposed on the mounting portion 22. In the present embodiment, the inner wall of the hollow portion 11 of the first counterweight 1A is provided with a mounting groove 15 that matches the mounting portion 22. The opening of the hoop body is reduced so that the mounting portion 22 can be accommodated and assembled in the mounting groove 15, and the opening of the hoop body is reset so that the mounting portion 22 is clamped and fixed in the mounting groove 15. The hoop body is squeezed by the user so that the hoop body shrinks along the opening. At this time, the hoop body is installed in the mounting groove 15 of the first counterweight 1A, and the squeezing of the hoop body is correspondingly released to restore it, so that it is clamped and fixed in the mounting groove 15, which is convenient for the installation and removal of the clamping member 2. Preferably, the mounting portion 22 is a plurality of protrusions arranged at the bottom of the hoop body by a spacer ring and convex relative to the circumferential projection of the hoop body, and each protrusion is controlled by an external force on the hoop body to move with the hoop body, so as to facilitate the assembly or removal to the mounting groove 15. Among them, multiple claw parts 23 are arranged at intervals along the circumference of the hoop body and are arranged at the top position of the hoop body. The inner side surfaces of multiple claw parts 23 are combined to form a cavity 21. The inner wall of the cavity 21 is provided with multiple clamping protrusions (not shown in the figure). The clamping protrusions make the connection between the claw part 23 and the external hose tighter, increase the friction fit between them, and make the fixing effect better. The outer side surface of the claw part 23 is a curved arc, which is controlled by the matching surface 12 to relatively shrink and hold the external hose accommodated in the cavity 21. It should be mentioned that the curved arc of the claw portion 23 is arranged from top to bottom, and the matching surface 12 located on the inner wall of the hollow portion 11 of the second counterweight block 1B is protruded inwardly and is arranged in a ring on the circumferential position of the hollow portion 11, corresponding to triggering each claw portion 23 in a curved arc shape, and the final abutment position of the claw portion 23 on the matching surface 12 can be adjusted accordingly according to the length of the claw portion 23 accommodated in the second counterweight block 1B, and then the deformation size of each claw portion 23 is controlled by the length of the claw portion 23 accommodated in the hollow portion 11 of the second counterweight block 1B, thereby adjusting the size of the cavity 21 when the clamping member 2 is clamped inward, and adapting to external hoses of different sizes and diameters.

[0041] The working mode of the weight of this embodiment is as follows:

[0042] When it is necessary to install the external hose inside the counterweight 1, one end of the clamping piece 2 is clamped and fixed to the first counterweight 1A, and the two openings are opposite to each other, and the external hose is assembled into the cavity 21 along the two openings. At this time, the hose is temporarily stored on the first counterweight 1A and the clamping piece 2. When it is assembled to the second counterweight 1B through the first counterweight 1A through the disassembly piece 3, the other end of the clamping piece 2 is clamped and placed on the second counterweight 1B along the hollow part 11 of the second counterweight 1B, and the mating surface 12 located on the second counterweight 1B abuts against the clamping piece 2 to trigger the clamping piece 2 to deform in the direction of holding the hose, thereby realizing the limited fixation of the hose in the hollow part 11 and the cavity 21 to tighten the hose in the counterweight 1. When it is necessary to remove the external hose from the inside of the counterweight block 1, the user releases the limit clamping of the detachment piece 3 on the two counterweight blocks 1, and detaches the first counterweight block 1A and the second counterweight block 1B from each other in the vertical direction. At this time, the clamping piece 2 placed in the hollow part 11 of the second counterweight block 1B is pulled in the vertical direction by the external force of the user, and elastically deforms inward and is pulled out to the hollow part 11. Then the hose is detached laterally from the first counterweight block 1A and the clamping piece 2, as well as the openings of the second counterweight block 1B to the outside of the hollow part 11 and the cavity 21.

[0043] It should be mentioned that there is no restriction on the order of assembling or detaching the external hose to the first counterweight 1A and the second counterweight 1B along the opening. The weight of the present application is also applicable to the installation method of directly inserting the hose into the weight. The external hose is directly inserted into the two counterweights 1 through the hollow part 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 diversified.

[0044] 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.
