Description

Technical Field

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

[0002] The faucet or shower controller is generally provided with a rotating control handle, and the current control handle is mostly fixed to the valve stem by screwing in a screw hole on the side. The above assembly structure has a major problem in that the general control handle itself is small in size and is compactly installed with the faucet or shower controller. Its screw hole is often very close to the valve stem extension of the faucet or shower controller, resulting in a narrow space for screwing in the screw, making it difficult to assemble. In many cases, it is necessary to remove the top cover or shielding structure of the faucet or shower controller body before disassembling the screws that fix the handle, which makes the disassembly and assembly of the handle cumbersome. It can be seen that the faucet handle and its assembly structure need to be improved. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a handle structure that can be quickly disassembled and assembled.

[0013] Preferably, the edges of the limit portion facing outward and inward are chamfered to facilitate the entry of the undercut, and at the same time, the user can pull out the assembled handle with force. The handle is provided with a clearance opening that runs through both ends, and one end of the clearance opening points to the protrusion of the undercut, forming a placement and withdrawal channel for the undercut mold core. The middle part of the outer periphery of the locking member is provided with an external hexagon coaxial with the locking member, and the user can screw the locking member into or out of the installation cavity of the faucet body through the external hexagon.

[0014] Preferably, the locking portion is fixedly assembled with the faucet body by means of threads, snaps or limiting holes, that is, the locking member can be removably installed on the faucet by means of threaded assembly, snap assembly or screws passing through the peripheral openings and limiting holes of the faucet mounting cavity.

[0015] Preferably, a key slot is provided at one end of the handle away from the locking member, and a key is provided in the key slot. In this case, the handle can be suitable for a valve core with dual functions, that is, a valve core with a rotating valve stem and a pressing function.

[0016] In a second aspect, a faucet is provided, comprising a faucet body, a valve core, and the handle assembly described in the first aspect. The faucet body is provided with an installation cavity, the valve core is inserted into the installation cavity, and the valve stem extends out of the faucet body.

The connection portion of the handle and the limiting portion of the locking member are rotatably connected, the valve stem passes through the locking member and is inserted into the handle, and the spline of the valve stem is engaged with the spline in the handle.

[0017] From the above description of the utility model, it can be seen that the utility model has the following beneficial effects:

[0018] The utility model replaces the traditional handle with a locking member and a handle, wherein the locking member can be fixed to the faucet body, and the handle is rotatably connected to the locking member, thereby replacing the traditional pin locking with a pressing and rotating fixation of the handle and the locking member, thereby improving the installation convenience of the handle;

[0019] At least one of the connecting portion and the limiting portion is an elastic member, which has expansion or contraction properties, which saves more effort during assembly and can avoid extrusion damage of the components;

[0020] A clearance opening is set on the handle to form a placement and exit channel for the undercut mold core, so that the handle can be molded in one piece, reducing the difficulty of molding;

[0021] The inner edge of the limiting portion is chamfered, so when replacing the valve core or the handle, the user can forcefully pull out the assembled handle, thereby avoiding damage to the handle or the locking member and ensuring that the handle can be completely disassembled.
