Description

Technical Field

[0001] This utility model belongs to the field of pull-out faucet technology, and specifically refers to a counterweight block for a pull-out faucet. Background Technology

[0002] Pull-out faucets are a common kitchen and bathroom fixture, allowing for more flexible water usage by pulling out the faucet body. The return of the pull-out faucet to its original position is achieved through a counterweight; the quality and position of the counterweight directly affect the smoothness and stability of the faucet's return.

[0003] In existing technology, the counterweight of a pull-out faucet is usually designed as two halves, with a through hole in the middle of each half. The pull-out water pipe passes through this through hole and is locked in place by means of clips or other methods. Friction between the pull-out water pipe and the inner wall of the through hole creates a limiting force. As a result, a single-specification counterweight can only be used with pull-out water pipes of a specific diameter, and cannot achieve universality. Furthermore, the stability of the counterweight depends on the stability of the clip structure. When repeatedly pulled and shaken, there is a certain possibility that the clips may loosen, causing the counterweight to fall off. Utility Model Content

[0004] The main purpose of this utility model is to provide a counterweight for a pull-out faucet, which solves the problems existing in the prior art, so that the counterweight can be adapted to pull-out water pipes of various sizes, and the structure is stable and will not fall off.

[0005] To achieve the above objectives, the solution of this utility model is: A counterweight for a pull-out faucet includes a counterweight body and a locking component. The counterweight body has a first through hole through its upper and lower ends for a pull-out water pipe to pass through, and a threaded hole coaxial with and communicating with the first through hole. The diameter of the threaded hole is larger than that of the first through hole, and a ring-shaped inclined surface is provided on the end face of the threaded hole adjacent to the first through hole. The locking component is threadedly fitted into the threaded hole, and a plurality of spring arms are provided on its inner end face. The spring arms are opposite to the ring-shaped inclined surface and deform inward as the locking component moves towards the through hole, abutting against the ring-shaped inclined surface to clamp the pull-out water pipe located within the first through hole.

[0006] The upper outer side of the spring arm is provided with a guide slope that is opposite to the ring slope.

[0007] The spring arms are arranged at equal angular intervals around the axis of the locking member.

[0008] The outer end face of the locking member is provided with at least two protrusions.

[0009] Preferably, only two tabs are provided, and they are arranged coplanarly along the same diameter of the locking member.

[0010] The locking element is provided with a second through hole for the pull-out water pipe to pass through.

[0011] Preferably, in the assembled state, the second perforation is coaxially arranged with the first perforation.

[0012] The joints between the annular bevel and the first through hole and screw hole are all rounded.

[0013] When the axis of the first perforation is perpendicular to the horizontal plane, the angle between the annular inclined plane and the horizontal plane is not less than 45° and less than 90°.

[0014] After adopting the above technical solution, the present invention has the following technical effects: This invention utilizes a threaded connection between the locking component and the screw hole of the counterweight body. This allows the relative distance between the locking component and the inclined ring to change as the locking component is screwed in and out of the screw hole. This alters the radial displacement of the spring arm as it deforms inward under pressure from the inclined ring. The counterweight can clamp pull-out water pipes of different sizes, increasing the product's versatility and flexibility. Simultaneously, tightening the locking component ensures sufficient pressure is applied to the surface of the pull-out water pipe by the spring arm, providing enough friction to limit the counterweight's movement and prevent it from sliding or falling off. Furthermore, this invention requires only two parts for the counterweight, reducing the number of components and facilitating processing and assembly. Attached Figure Description

[0025] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0026] refer to Figures 1 to 5 The first embodiment of the present invention is shown, which is a pull-out faucet counterweight block, including a counterweight body 10 and a locking member 20; A first through hole 11 for the pull-out water pipe 30 to pass through is provided between the upper and lower ends of the counterweight body 10, and a screw hole 12 coaxial with and connected to the first through hole 11; the diameter of the screw hole 12 is larger than that of the first through hole 11, and a ring bevel 13 is provided on the end face of the screw hole 12 near the first through hole 11. The locking member 20 is threadedly fitted into the screw hole 12, and its inner end face is provided with a number of spring arms 21. The spring arms 21 are opposite to the ring inclined surface 13, and as the locking member 20 moves toward the through hole 21, they abut against the ring inclined surface 13 and deform inward to clamp the pull-out water pipe 30 located in the first through hole 11.

[0027] See above for details. Figure 5 This invention utilizes the threaded connection between the locking member 20 and the screw hole 12 of the counterweight body 10. This allows the locking member 20 to change the relative distance between its body and the inclined surface 13 during screwing into and out of the screw hole 12. This alters the radial displacement of the spring arm 21 as it is compressed inward by the inclined surface 13. The counterweight can clamp pull-out water pipes 30 of different sizes, increasing the product's versatility and flexibility. Simultaneously, tightening the locking member 20 ensures sufficient pressure is applied to the surface of the pull-out water pipe 30 by the spring arm 21, providing enough friction to limit the counterweight's movement and prevent it from sliding or falling off. Furthermore, the counterweight requires only two parts, reducing the number of components and facilitating processing and assembly.

[0028] The following shows the structural details of the first embodiment: The upper outer side of the aforementioned spring arm 21 is provided with a guide slope 22 opposite to the annular slope 13. Therefore, when the end of the spring arm 21 contacts the annular slope 13, it can deform more smoothly inward along the annular slope 13, avoiding excessive friction noise and optimizing the user experience.

[0029] The aforementioned spring arms 21 are provided in four units, with a certain interval reserved between adjacent spring arms 21. All spring arms 21 are arranged at equal angular intervals around the axis of the locking member 20. This ensures that after the locking member 20 is screwed into the screw hole 12, each spring arm 21 can be evenly stressed, thereby ensuring that the relative positions of the pull-out water pipe 30 are also evenly stressed.

[0030] The outer end face of the locking member 20 is provided with at least two protrusions 23, which makes it convenient for the user to turn the locking member 20 by hand without the need for tools, and the position of the locking member 20 and the locking degree of its spring arm 21 can be adjusted at any time.

[0031] Furthermore, only two of the aforementioned tabs 23 are provided, and they are arranged coplanarly along the same diameter of the locking member 20.

[0032] The locking member 20 is provided with a second through hole 24 for the pull-out water pipe 30 to pass through. In the assembled state, the second through hole 24 is coaxially arranged with the first through hole 11.

[0033] The joints between the aforementioned annular inclined surface 13 and the first through hole 11 and screw hole 12 are all rounded to achieve a smooth transition.

[0034] Taking the first perforation 11 as an example where the axial direction is perpendicular to the horizontal plane, the angle between the above-mentioned annular inclined surface 13 and the horizontal plane is not less than 45° and less than 90°, making it easier for the spring arm 21 to deform inward when it contacts the annular inclined surface 13, and the resistance to the axial movement of the locking member 20 will be relatively small.

[0035] refer to Figures 6 to 9 As shown, the second embodiment of the present invention is illustrated, which is also a counterweight block for a pull-out faucet. Most of its structure is the same as that of the first embodiment. The main difference between the two lies in the shape of the counterweight body 10: the counterweight body 10 in the first embodiment has an approximately cylindrical side surface, and rounded corners are provided at the edges of both end faces to achieve a smooth transition; the counterweight body 10 in the second embodiment has an approximately ellipsoidal side surface that is larger in the middle and smaller at both ends, and rounded corners are also provided at the edges of both end faces to achieve a smooth transition.

[0036] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
