Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a faucet with a handle alignment structure. Background Art

[0002] The handle of the faucet is directly docked with the valve stem, and mostly adopts screw or pin fixing methods. After the faucet handle is installed, it is prone to the problem of skew. Especially for the rotary handle, it is easier to feel that the handle is installed skew when rotating. The main reason for the skew installation of the handle is that during the assembly of the faucet valve core, even if there is a small error in the valve core assembly, when the error expands along the axial direction of the valve core, at the installation position of the handle, an obvious assembly error can be seen with the naked eye. The gap between the end of the handle and the installation port of the faucet valve core is significantly uneven, one side is wide and the other side is narrow, and the texture of the product is poor. Summary of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides an alignment structure that can avoid the skew of the handle after installation.

[0004] A faucet with a handle alignment structure includes a faucet body, a valve core and a handle. Among them,

[0005] The faucet body is provided with an installation cavity, the valve core is installed in the installation cavity, and the valve stem extends out. A docking end is formed at the opening of the installation cavity.

[0006] One of the docking end and the end edge of the handle facing the faucet body is provided with an annular docking step, and the other is provided with an alignment protrusion. During the assembly process, the handle is sleeved on the valve stem, the alignment protrusion and the docking step are sleeved with each other, and after the end of the handle fits with the docking end of the installation cavity, the handle is fixedly assembled with the valve stem. Here, the fixed assembly can be by means of screws, pins or snap fasteners.

[0007] By setting the docking step and the alignment protrusion, during the assembly, through the mutual sleeving of the docking step and the alignment protrusion, and also through the fitting of the end of the handle with the docking end of the installation cavity, the two-direction restrictions are used to offset the assembly error of the valve core and the error existing in the valve stem. After the handle is fixedly assembled and rotated, it can maintain a consistent relative state with the faucet body, solving the problems of skew or significantly uneven gaps existing after the traditional handle is installed.

[0008] Preferably, the alignment protrusion is also annular, with a simple structure and easy to form.

[0009] Preferably, the alignment protrusion is composed of several annularly spaced convex columns.

[0010] Preferably, in order to be able to hide the alignment protrusion, the docking step is provided on the inner ring of the opening of the installation cavity, the alignment protrusion is inserted into the docking step, and the outer diameter of the alignment protrusion is equal to the inner diameter of the docking step.

[0011] Preferably, to improve the convenience of assembly, the outer edge of the end of the alignment protrusion is rounded or chamfered, and the inner ring of the opening of the installation cavity of the docking step is rounded or chamfered.

[0012] Preferably, a wear-resistant ring is provided at the joint where the handle and the docking end of the installation cavity are in contact to avoid wear of the components.

[0013] Preferably, to reduce the forming difficulty of the handle, the handle includes a mounting base and a decorative cover. The handle is assembled with the valve stem through the mounting base. The alignment protrusion is provided at the end of the mounting base facing the faucet body, and the decorative cover covers the outer circumference of the mounting base.

[0014] Preferably, a wear-resistant ring is formed on the outer circumference of the alignment protrusion of the mounting base, and both ends of the wear-resistant ring are respectively in contact with the end of the decorative cover and the docking end of the installation cavity.

[0015] Preferably, the handle further includes a rod. A plugging groove for inserting the valve stem is provided in the middle of the mounting base, and a threaded hole perpendicular to and communicating with the plugging groove is provided on the circumference of the mounting base. The decorative cover is provided with a relief hole corresponding to the threaded hole. One end of the rod passes through the relief hole and is screwed into the threaded hole, and the end abuts against the valve stem to fix the handle and the valve stem.

[0016] Preferably, guide strips perpendicular to the direction of the valve stem are provided on the circumference of the mounting base, and guide grooves for restricting the guide strips are provided inside the decorative cover, so as to avoid incorrect installation directions when installing the mounting base and the decorative cover.

[0017] As can be seen from the above description of the present invention, the present invention has the following beneficial effects:

[0018] By providing a docking step and an alignment protrusion, during assembly, through the mutual nesting of the docking step and the alignment protrusion, and also through the contact between the end of the handle and the docking end of the installation cavity, the alignment errors of the valve core assembly and the errors existing in the valve stem are offset by the restrictions in two directions. After the handle is fixedly assembled and rotated, it can maintain the same relative state as the faucet body, solving the problems of skew or significantly uneven gaps existing after the traditional handle is installed;
