Description

Technical Field

[0001] The invention relates to the technical field of bathroom accessories, and in particular to a weight structure. Background Art

[0002] The pull-out faucet is a common faucet structure on the market. It is made by installing a weight at the bottom of the pull-out tube in the faucet. Under the action of the weight, the hose can automatically retract due to the weight of the weight, which is extremely convenient to use. At present, the weight of the pull-out faucet installed on the hose is generally divided into two categories. 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 for fixing. The other way 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.

[0004] In view of this, the applicant filed this application after studying the existing technology. Summary of the invention

[0005] The present invention provides a weight structure, aiming to improve at least one of the above technical problems.

[0006] In order to solve the above technical problems, the present invention provides a weight structure, including a weight body for being configured on a pulling tube, the weight body forming an open hollow groove for installing the pulling tube; a receiving groove penetrating to the outer wall of the weight body is formed on one side wall of the hollow groove; a clamping assembly is arranged in the receiving groove, the clamping assembly includes a clamping member and an adjusting member for allowing the clamping member to approach or move away from the other side wall of the hollow groove; the pulling tube can extend into the hollow groove along the opening of the hollow groove, so that the clamping end of the clamping member can clamp and fix the weight body on the pulling tube when it approaches the other side wall.

[0007] As a further optimization, the accommodating groove is rectangular, and the clamping member is slidably connected to the accommodating groove; a threaded hole is provided on the side of the clamping member away from the clamping end, and the adjusting member is provided with a threaded end adapted to be connected to the threaded hole.

[0008] As a further optimization, a conical portion is protruding outward from the outer port of the accommodating groove, and a groove for inserting and installing a clamping ring is provided above and below the conical portion; the adjusting member is provided with an annular groove; when the annular groove is located between the upper and lower grooves, the clamping ring can pass through the conical portion and the annular groove from the groove, thereby limiting the axial position of the adjusting member in the accommodating groove.

[0009] As a further optimization, a knob portion is provided on a side of the adjusting member away from the threaded end, and the knob portion can rotate against the end surface of the truncated cone portion.

[0010] As a further optimization, the clamping end of the clamping piece is provided with a clamping groove suitable for abutting against the pulling tube.

[0011] As a further optimization, a plurality of first boss portions for abutting against the pulling tube are formed on the clamping groove.

[0012] As a further optimization, a plurality of second boss portions for abutting against the pull-out tube are formed in the hollow groove.

[0013] As a further optimization, a groove platform is provided in the hollow groove, and the groove platform is connected with the accommodating groove; when the pulling tube is clamped between the clamping end of the clamping member and the inner wall of the hollow groove, an accommodating cavity is formed between the end of the clamping member and the table end of the groove platform.

[0014] As a further optimization, the diameter of the pulling tube is less than or equal to the distance between the inner walls on both sides of the hollow groove.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] The present application provides a weight structure, which can quickly place the pull-out tube inside the weight body through an open hollow groove, and at the same time, by rotating the knob part, the adjusting part drives the clamping part to move in the accommodating groove, so as to cooperate with the groove wall of the hollow groove to clamp the pull-out tube tightly and quickly complete the installation. Among them, a groove platform is provided in the hollow groove, and a receiving cavity is formed between the groove platform and the end of the clamping part. When the clamping is too tight, a receiving space can be reserved for local deformation of the pull-out tube, thereby avoiding damage to the pull-out tube and improving the service life. In addition, the hollow groove in the present application is suitable for assembly and fixation of pull-out tubes of various diameters with the clamping part, and has high adaptability.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Depend on Figures 1 to 5As shown, an embodiment of the present invention provides a weight structure, including a weight body 1 for being arranged on a pull-out tube 2, the weight body 1 being formed with an open hollow groove 3 for installing the pull-out tube 2, wherein the hollow groove 3 passes through the weight body 1 from top to bottom, and is connected to the outer wall and is provided with an opening, so as to be U-shaped and open in cross section. As a preferred embodiment, a receiving groove 4 is provided on one side wall of the hollow groove 3 located in the middle part of the weight body 1, and a clamping assembly 5 is arranged in the receiving groove 4, and the clamping assembly 5 includes a clamping member 6 and an adjusting member 7 for allowing the clamping member 6 to approach or move away from the other side wall of the hollow groove 3. In this embodiment, the receiving groove 4 is arranged in a rectangular shape, and the clamping member 6 is adapted to be slidably connected with the receiving groove 4 to facilitate the clamping end of the clamping member 6 to abut against the pull-out tube 2. The pull-out tube 2 can be extended into the hollow groove 3 along the opening of the hollow groove 3, and is arranged between the clamping end of the clamping member 6 and the other side wall of the hollow groove 3, so that the clamping member 6 can clamp and fix the weight body 1 on the pull-out tube 2 when it is close to the other side wall, and the installation process is fast and convenient. Preferably, the diameter of the pull-out tube 2 is less than or equal to the distance between the inner walls on both sides of the hollow groove 3, that is, the pull-out tube 2 can be most common or various different thickness models currently on the market, and can be extended into the weight body 1 through the opening, and finally fixed and installed by the clamping member 6.

[0026] As a preferred embodiment, a truncated cone 8 is provided at the outer end of the receiving groove 4, and a slot 10 for inserting and installing a snap ring 9 is provided on the upper and lower sides of the truncated cone 8, wherein two slots 10 are provided at intervals on the upper side of the truncated cone 8, and two slots 10 are provided at intervals on the lower side, and the upper and lower four slots 10 are arranged in an interlaced manner with the axis of the truncated cone 8 as the midpoint. The adjusting member 7 is coaxially provided with an annular groove 11; when the annular groove 11 is located between the upper and lower slots 10, the snap ring 9 can pass through the truncated cone 8 and the annular groove 11 from the slot 10, thereby axially limiting the adjusting member 7 in the receiving groove 4, so that the adjusting member 7 is axially limited relative to the receiving groove 4, but can still rotate, so as to control the movement of the clamping member 6. As a preferred embodiment, the notch end of the annular groove 11 can be adapted to rotate in the receiving groove 4, so as to better ensure its stability.

[0027] Among them, as a preferred embodiment, the retaining ring 9 is an elastic member in a U-shape. Furthermore, the shape is a peanut with an opening. The arc portion close to the opening end can be adapted to be clamped on both sides of the bottom of the annular groove 11, and the side away from the opening end can extend from one side of the truncated cone portion 8 when the clamping limit is reached, thereby facilitating the operator to quickly install and disassemble.

[0028] Preferably, a threaded hole is provided on the side of the clamping member 6 away from the clamping end, and the adjusting member 7 is provided with a threaded end adapted to be connected to the threaded hole. In the present embodiment, since the adjusting member 7 is limited by the retaining ring 9, the clamping member 6 can be driven to approach or move away from the hollow groove 3 through the thread by rotating the adjusting member 7, thereby implementing the clamping or releasing operation.

[0029] Furthermore, as a preferred embodiment, a knob portion 12 is provided on the side of the adjusting member 7 away from the threaded end, and the knob portion 12 can be rotated to abut against the end surface of the truncated cone portion 8. By rotating the knob portion 12, the adjusting member 7 can control the movement of the clamping member 6 threadedly connected thereto, thereby clamping or releasing the pulling tube 2. Furthermore, when the adjusting member 7 is limited by the clamping ring 9, the inner end of the knob portion 12 just abuts against the end surface of the truncated cone portion 8, thereby closing the outer end of the accommodating groove 4 and making the structure more compact.

[0030] Preferably, the clamping end of the clamping member 6 is formed with a clamping groove 13 suitable for abutting against the pull-out tube 2. The cross section of the clamping groove 13 is mainly arranged in an arc shape, so that it can better abut against the outer wall of the pull-out tube 2 for clamping. It should be noted that the depth of the clamping groove 13 is relatively shallow, preferably smaller than the radius of most types of pull-out tubes 2, so that it can abut against pull-out tubes 2 of more different specifications. Among them, when clamping, since in this embodiment, the hollow groove 3 is arranged in a U shape, the other side of the pull-out tube 2 can have a partially arc-shaped surface that abuts against the arc-shaped groove wall of the hollow groove 3.

[0031] Preferably, the clamping groove 13 is formed with a plurality of first bosses 14 for abutting against the pull-out tube 2. In this embodiment, the first bosses 14 are arranged in two rows on the upper and lower inner walls of the clamping groove 13, so that the pull-out tube 2 can be better clamped and locked when clamped.

[0032] Preferably, a plurality of second bosses 15 for abutting against the pull-out tube 2 are formed in the hollow groove 3. In this embodiment, the second bosses 15 are arranged in multiple rows of strips, specifically three rows at intervals, so that when the pull-out tube 2 is clamped, it can be better clamped, locked and fixed. Further, as an embodiment, the first boss 14 and the second boss 15 can be arranged at staggered intervals to achieve a better clamping and locking effect.

[0033] Preferably, a groove platform 16 is provided in the hollow groove 3, the groove platform 16 is connected with the accommodating groove 4, and the groove platform 16 is flush with the side wall of the cavity wall of the accommodating groove 4, so that the clamping member 6 can move from the accommodating groove 4 to the table end 17 of the groove platform 16. Preferably, when the pull-out tube 2 is clamped between the clamping end of the clamping member 6 and the inner side wall of the hollow groove 3, an accommodating cavity 18 is formed between the end of the clamping member 6 and the table end 17 of the groove platform 16. In this way, when the pull-out tube 2 is clamped and fixed by the clamping member 6, if the clamping force is too large, if it is limited by space, the stress between the local structures of the clamped part of the pull-out tube 2 will increase. If it is under high stress for a long time, it will affect the stability and life of the pull-out tube 2 structure, and then damage the pull-out tube 2. Preferably, in this embodiment, by providing a receiving cavity 18 between the clamping end and the table end 17, when the clamping is too tight, a receiving space can be reserved for local deformation of the pull-out tube 2, thereby avoiding damage to the pull-out tube 2 and increasing its service life.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
