TECHNICAL FIELD
[0001] The utility model relates to a handle assembly for valve core and valve assembly. BACKGROUND
[0002] In the prior art, the structure of a conventional handle is generally directly fixedly connected with a valve shaft of a valve core, and is used for controlling opening, closing and temperature adjustment of water flow. Specifically, the operation of the handle includes two main actions: firstly, the handle drives the valve shaft to swing, thereby controlling the opening and closing of the water flow; secondly, in the process of temperature adjustment, the handle is further rotated to drive the valve shaft to rotate around the axis of the valve core, so as to adjust the mixing ratio of cold and hot water. In this process, since the handle is fixed on the valve shaft, all operations need to rely on the movement of the valve shaft. One feature of this design is that the movement track of the handle slides and rotates along a hemispherical surface. When a user operates the handle, an arc-shaped track change is felt in the hand. Although this design can meet the basic requirements in functionality, the appearance design is greatly limited. SUMMARY
[0003] The utility model aims at overcoming the deficiency in the prior art, and provides a handle assembly for valve core which can realize sliding and rotation on a plane.
[0004] In order to solve the above technical problems, the utility model provides a handle assembly for valve core, the valve core is arranged on a valve seat, the handle assembly comprises a base, a handle and a connecting structure;
[0005] The connecting structure comprises a positioning bushing and a connecting rod, the base is connected with the valve seat, the positioning bushing is connected with the handle, and the base is clamped between the positioning bushing and the handle; the first end of the connecting rod is fixedly connected with the valve shaft of the valve core, and the second end of the connecting rod is movably connected with the handle; the handle can slide relative to a plane of the base to open the valve core, and the handle can rotate relative to the base to adjust the water temperature of the valve core.

[0008] In a more preferable embodiment, the connecting structure further comprises a sliding rod, and the sliding rod is transversely arranged on the second end of the connecting rod.
[0009] The handle comprises a sliding groove extending upward and downward, and the sliding rod can slide in the sliding groove upward and downward.
[0010] In a more preferable embodiment, the bottom surface of the handle is provided with two protrusions, and the surfaces of the two protrusions facing each other are provided with grooves, and the two grooves form the sliding groove, and the two ends of the sliding rod slide in the two grooves.
[0011] In a more preferable embodiment, one side of the positioning bush is fixedly connected with the two protrusions of the handle through two screws.
[0012] In a more preferable embodiment, the handle is in a cylindrical shape, and the handle slides on the upper surface of the base.
[0013] In a more preferable embodiment, the edge of one side of the positioning bush can correspondingly abut against the circumference of the base.

[0016] The valve core is arranged in the valve cavity, the upper cover is connected with the valve cavity and fixes the valve core, the locking valve body is used to pass through the mounting hole of the table surface, and the mounting nut is threadedly connected with the locking valve body.
[0017] Compared with the prior art, the technical scheme of the utility model has the following beneficial effects:
[0018] The connecting structure comprises a positioning bushing and a connecting rod, the base is connected with the valve seat, the positioning bushing is connected with the handle, and the base is clamped between the positioning bushing and the handle; the first end of the connecting rod is fixedly connected with the valve shaft of the valve core, and the second end of the connecting rod is movably connected with the handle; the handle can slide relative to a plane of the base to open the valve core, and the handle can rotate relative to the base to adjust the water temperature of the valve core. During rotation and sliding of the handle, the handle only moves along the plane of the base. This design greatly simplifies the operation path, so that the user does not need to perform complex three-dimensional operations when controlling the water flow switch or adjusting the temperature. Since the movement of the handle is limited in the plane of the base, the entire operation process is more intuitive and smooth, and the possibility of misoperation is reduced. The plane movement design provides greater flexibility for the appearance design of the handle. Unlike the traditional handle which needs to perform three-dimensional movement around a spherical surface or an axis, the present design no longer relies on complex geometric movement forms, so it can support a more concise and modern appearance shape. The simplified movement mode makes the handle assembly more delicate and fashionable in appearance, meeting the current user's demand for the appearance beauty of home products, while ensuring the perfect combination of design and function.
