Description

Technical Field

[0001] The utility model relates to the technical field of bathroom accessories, and particularly to a weight structure. Background Art

[0002] The pull-out faucet is a common faucet structure in the market. A weight is installed at the bottom of the pull-out pipe inside the faucet. Under the action of the weight, the hose can automatically retract by the weight of the weight, which is extremely convenient to use. At present, the installation of the weight on the hose of the extraction faucet is generally divided into two categories. One is that the weight needs to be customized according to the size of the hose, and then fixed on the hose through 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 way is to use fasteners such as bolts to connect the weight block. This method has a complex structure, and the installation and disassembly are relatively cumbersome. Even after using for a period of time, the bolts are prone to rust, and there is a risk of being unable to disassemble. Or, a through hole is directly designed in the middle of the weight for the hose to pass through to realize the hanging of the weight on the hose to achieve the corresponding function. For the way of passing through and sleeving with the through hole, it is only applicable to hoses of a single specification size, and there are 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, and the operation is extremely inconvenient.

[0004] In view of this, the applicant has put forward this application after studying the existing technologies. Summary of the Utility Model

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

[0006] To solve the above technical problems, the utility model provides a weight structure, which includes a weight body configured on a pull-out pipe. The weight body is formed with an open hollow groove for installing the pull-out pipe.

The clamping assembly includes a clamping member and an adjusting member for moving the clamping member closer to or away from the other side wall of the hollow groove. The pull-out pipe 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 pull-out pipe when approaching the other side wall.

[0007] As a further optimization, the receiving groove is rectangularly arranged, and the clamping member is slidably connected with the receiving groove in a matching manner. A threaded hole is arranged on the side of the clamping member away from the clamping end, and the adjusting member is provided with a threaded end that is connected with the threaded hole in a matching manner.

[0008] As a further optimization, a frustum portion is provided protruding outward at the outer port of the receiving groove, and a clamping groove for inserting and installing a clamping ring is provided through the frustum portion up and down; an annular groove is provided on the adjusting member; when the annular groove is located between the upper and lower clamping grooves, the clamping ring can pass through the frustum portion and the annular groove from the clamping groove, thereby axially limiting the adjusting member in the receiving groove.

[0009] As a further optimization, a knob portion is provided on the side of the adjusting member away from the threaded end, and the knob portion can rotatably abut against the end face of the frustum portion.

[0010] As a further optimization, the clamping end of the clamping member is configured with a clamping groove adapted to abut against the draw tube.

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

[0013] As a further optimization, a groove table portion is provided in the hollow groove, and the groove table portion communicates with the receiving groove; when the draw tube is clamped between the clamping end of the clamping member and the inner side wall of the hollow groove, a receiving cavity is formed between the end of the clamping member and the table surface end of the groove table portion.

[0014] As a further optimization, the diameter of the draw 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 solutions, the following technical effects can be achieved by the present utility model:

[0016] A weight structure provided by the present application can quickly place the draw tube inside the weight body through the open hollow groove. At the same time, by rotating the knob portion, the clamping member is driven by the adjusting member to move in the receiving groove, so as to cooperate with the groove wall of the hollow groove to tightly clamp the draw tube and quickly complete the installation. Among them, a groove table portion is provided in the hollow groove, and a receiving cavity is formed between the groove table portion and the end of the clamping member, which can leave a receiving space for local deformation of the draw tube when the clamping is too tight, thereby avoiding damage to the draw tube and improving the service life. And the hollow groove in the present application cooperates with the clamping member to be suitable for assembling and fixing draw tubes of various different pipe diameters, with high adaptability.

Specific embodiments

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the attached drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0025] By Figures 1 to 5As shown in the figure, an embodiment of the utility model provides a weight structure, which includes a weight body 1 configured on a draw tube 2. The weight body 1 is formed with an open hollow groove 3 for installing the draw tube 2. Among them, the hollow groove 3 penetrates the weight body 1 up and down and is communicated with the outer side wall to be provided with an opening, so that it is arranged in a U-shaped open manner in cross-section. As a preferred embodiment, a receiving groove 4 is opened on one side wall of the hollow groove 3 at the middle part of the weight body 1, and a clamping assembly 5 is arranged in the receiving groove 4. The clamping assembly 5 includes a clamping member 6 and an adjusting member 7 for moving the clamping member 6 closer to or farther 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 slidably connected to the receiving groove 4 in a matching manner to facilitate the clamping end of the clamping member 6 to abut against the draw tube 2. The draw tube 2 can extend 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 draw tube 2 when approaching the other side wall, and the installation process is fast and convenient. Preferably, the diameter of the draw 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 draw tube 2 can be most of the common or various different thickness models on the market at present, and can extend into the weight body 1 through the opening and finally be fixedly installed by the clamping member 6.

[0026] Among them, as a preferred embodiment, a frustum 8 protrudes outward at the outer port of the receiving groove 4. The frustum 8 is provided with a clamping groove 10 for inserting and installing a clamping ring 9 up and down. Among them, two clamping grooves 10 are arranged at intervals on the upper side of the frustum 8, and two clamping grooves 10 are arranged at intervals on the lower side. The four clamping grooves 10 up and down are staggered with the axis of the frustum 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 clamping grooves 10, the clamping ring 9 can pass through the frustum 8 and the annular groove 11 from the clamping groove 10, so as to axially limit the adjusting member 7 in the receiving groove 4, so that the adjusting member 7 is axially restricted from displacement relative to the receiving groove 4, but can still rotate, so as to control the movement of the clamping member 6. Among them, as a preferred embodiment, the notch end of the annular groove 11 can be rotatably matched in the receiving groove 4, so as to better ensure its stability.

[0027] Among them, as a preferred embodiment, the clamping ring 9 is an elastic member with a U-shaped shape. Further, it is in the shape of a peanut with an opening. The arc part near the opening end can be clamped and matched on both sides of the bottom of the annular groove 11, and one side far from the opening end can extend out from one side of the frustum 8 during clamping and limiting, so as to facilitate the operator to quickly install and disassemble.

[0028] Preferably, a threaded hole is provided on one 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 this embodiment, since the adjusting member 7 is limited by the snap ring 9, by rotating the adjusting member 7, the clamping member 6 can be driven by the thread to approach or move away from the hollow groove 3, thereby implementing the clamping or loosening operation.

[0029] Further, as a preferred embodiment, a knob portion 12 is provided on one side of the adjusting member 7 away from the threaded end. The knob portion 12 can rotate and abut against the end face of the frustum portion 8. By rotating the knob portion 12, the adjusting member 7 can be controlled to move the clamping member 6 connected to it by thread, so as to clamp or loosen the draw tube 2. Further, when the adjusting member 7 is limited by the snap ring 9, the inner end of the knob portion 12 just abuts against the end face of the frustum portion 8, so that the outer end port of the accommodating groove 4 can be closed, and the structure is also made more compact.

[0030] Preferably, a clamping groove 13 adapted to abut against the draw tube 2 is formed at the clamping end of the clamping member 6. The cross-section of the clamping groove 13 is mainly arc-shaped, so that it can better abut against the outer wall of the draw tube 2 for clamping. It should be noted that the depth of the clamping groove 13 is relatively shallow, preferably less than the radius of most models of the draw tube 2, so that it can abut against more draw tubes 2 of different specifications. Among them, when clamping, since the hollow groove 3 is U-shaped in this embodiment, a part of the arc surface of the other side of the draw tube 2 can abut against the arc-shaped groove wall of the hollow groove 3.

[0031] Preferably, a plurality of first convex portions 14 for abutting against the draw tube 2 are formed on the clamping groove 13. In this embodiment, the first convex portions 14 are arranged in two rows and multiple on the upper and lower inner side walls of the clamping groove 13, so that when clamping the draw tube 2, it can be better clamped and locked.

[0032] Preferably, a plurality of second convex portions 15 for abutting against the draw tube 2 are formed in the hollow groove 3. In this embodiment, the second convex portions 15 are arranged in multiple rows in a strip shape, specifically in three rows at intervals, so that when clamping the draw tube 2, it can be better clamped and locked. Among them, further, as an embodiment, the first convex portions 14 and the second convex portions 15 can be arranged in an alternating and spaced manner, so as to achieve a better clamping and locking effect.

[0033] Preferably, a groove table portion 16 is provided in the hollow groove 3. The groove table portion 16 communicates with the accommodation groove 4, and the side wall of the groove table portion 16 close to the cavity wall of the accommodation groove 4 is flush. Thus, the clamping member 6 can move from the accommodation groove 4 to the table surface end 17 of the groove table portion 16. Preferably, when the draw tube 2 is clamped between the clamping end of the clamping member 6 and the inner side wall of the hollow groove 3, an accommodation cavity 18 is formed between the end of the clamping member 6 and the table surface end 17 of the groove table portion 16. In this way, when the draw tube 2 is clamped and fixed by the clamping member 6, if the clamping force is too large or restricted by space, the stress between the local structures of the clamped part of the draw tube 2 will increase. If it is in a high-stress situation for a long time, it will affect the structural stability and service life of the draw tube 2, and further damage the draw tube 2. Preferably, in this embodiment, by providing the accommodation cavity 18 between the clamping end and the table surface end 17, a accommodation space for the local deformation of the draw tube 2 can be left when the clamping is too tight, thereby avoiding damage to the draw tube 2 and improving the service life.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. 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.
