Description

Technical Field

[0001] The utility model relates to a faucet handle structure. Background Art

[0002] Plastic faucets are generally made of PVC, ABS, PP and other materials through mass production through molds. Compared with other materials, plastic faucets are light, scale-free, odorless, rust-free, cheap, easy to construct, and widely used in various fields of life. However, after the existing plastic faucets are once injected, the handle is light in weight and has poor texture. It is also easy to break as the use time increases, and the service life is short. Therefore, handles with counterweights have appeared.

[0003] For example, in the invention patent application with Chinese invention patent application number 201710265415.5 and the invention name of a self-weighted faucet handle and its production process, a first counterweight block is arranged in the handle body close to the closed end, a cover is arranged on the inner wall of the handle body, and the first counterweight block is pressed against the closed end in the handle body, a positioning block is arranged at the upper end of the cover, and a positioning hole is arranged on the first counterweight block that passes through the upper and lower parts and corresponds to the positioning block, and the positioning block extends into the positioning hole; a valve stem connection part is arranged at the lower end of the cover, and the valve stem is connected to the valve stem connection part; finally, the faucet handle is formed by integral injection molding by injecting injection liquid into the mold through the injection channel at the valve stem connection part. Although the handle is provided with a counterweight block, the valve stem connection part of the handle needs to be fixed to the handle body by secondary injection molding, which has low assembly efficiency and high cost.

[0031] Please refer to Figures 1 to 4 A preferred embodiment of a faucet handle structure includes a handle body 10, a counterweight block 20 and a pressure cover 30.

[0032] The handle body 10 is provided with a handle 11 and a receiving cavity 12 with an opening at the top. A positioning block 13 extending along the height direction of the receiving cavity 12 is provided on the bottom surface of the receiving cavity 12 . The positioning block 13 is provided with a snap structure 14 .

[0033] In this embodiment, the positioning block 13 is square and includes two suspended edges 15 arranged opposite to each other. The tops of the two suspended edges 15 are provided with the buckle structures 14. Figure 2 As shown, the two suspended edges 15 are arranged in a front-to-back spacing.

[0034] Preferably, the positioning block 13 is integrally formed with the handle body 10 .

[0035] The counterweight block 20 is located in the accommodating cavity 12 and is sleeved on the outer periphery of the positioning block 13. In this embodiment, the counterweight block 20 is annular.

[0036] The pressure cover 30 is provided with a positioning hole 31 which passes through from top to bottom. The pressure cover 30 is located in the accommodating cavity 12 and is sleeved on the outer periphery of the positioning block 13. The buckle structure 14 is buckled with the pressure cover 30 to fix the pressure cover 30 in the accommodating cavity 12 and press it against the counterweight 20.

[0037] In this embodiment, the positioning hole 31 is square, and the buckle structure 14 is directly buckled on the top surface of the positioning hole 31 .

[0038] In this embodiment, Figure 3 As shown, a thickened portion 32 is provided at the inner wall of the top opening of the positioning hole 31 , and the buckle structure 14 is buckled on the top surface of the thickened portion 32 .

[0039] In this embodiment, a longitudinally extending positioning column 16 is disposed on the inner wall of the accommodating cavity 12 , and a positioning groove 33 which fits with the positioning column 16 is disposed on the outer periphery of the pressure cover 30 .

[0040] In this embodiment, the positioning block 13 is also provided with a valve shaft hole 17 for installing the valve shaft of the valve core, and the pressure cover 30 is also provided with a nut chamber 34 connected to the positioning hole 31, and is further provided with a screw (not shown in the figure) and a nut 40. The nut 40 is placed in the nut chamber 34, and the valve shaft of the valve core extends into the valve shaft hole 17. The screw is threadedly engaged with the nut 40 and the end thereof extends into the valve shaft hole 17 and locks the valve shaft of the valve core.

[0041] In this embodiment, the handle body 10 is further provided with an insertion hole 18 which transversely penetrates the accommodating cavity 12 . The insertion hole 18 corresponds to the screw hole of the nut 40 . The screw is inserted into the insertion hole 18 and then threadedly engaged with the nut 40 .

[0042] In this embodiment, the top of the gland 30 is also provided with a visible stop hole 35 connected to the nut cavity 34, and the nut 40 can extend out of the visible stop hole 35. When installing the nut 40, the visible stop hole 35 can visually see the assembly position of the nut 40 to determine whether it is installed in place.

[0043] The assembly process of the handle structure is as follows: first, place the counterweight 20 in the accommodating cavity 12 and sleeve it on the outer periphery of the positioning block 13, then place the pressure cover 30 in the accommodating cavity 12 so that the positioning column 16 corresponds to the positioning groove 33, and then extend the positioning block 13 into the positioning hole 31 until the buckle structure 14 buckles on the top surface of the thickened portion 32, and the installation of the handle structure is completed. When the handle structure needs to be fixed to the valve shaft of the valve core, it is only necessary to first install the nut 40 into the nut cavity 34, and the top of the nut 40 extends out of the visible limit hole 35, and then extend the valve shaft into the valve shaft hole 17, and finally pass the screw through the insertion hole 18 and screw it with the nut 40 and lock the valve shaft.

[0044] Since the handle structure of the present application is provided with a counterweight 20, the weight and texture of the handle can be improved. In addition, the handle structure is provided with a positioning block 13 on the bottom surface of the accommodating cavity 12, and the positioning block 13 is provided with a buckle structure 14. The buckle structure 14 is engaged with the pressure cover 30 to fix the pressure cover in the accommodating cavity 12 and press against the counterweight 20, thereby eliminating the need for secondary injection molding or welding operations, greatly simplifying the assembly steps and saving costs.
