Abstract

A knob includes a body, a rear end of the body having an annular cavity with a rear opening, a connecting column in the center of the annular cavity, and a plug hole on the connecting column. The knob is special in that: the body is made of transparent plastic material; it also includes a lamp holder and at least three lamp groups arranged on the lamp holder, the center of the lamp holder has a through hole, the lamp holder is circular and evenly arranged with at least three lamp groups; the through hole of the lamp holder cooperates with the connecting column, the lamp holder is fixed in the annular cavity, and the lamp group is located in the annular cavity between the bottom plate of the annular cavity and the lamp holder. Due to the use of such a structure, when the knob is rotated, at different control positions, the corresponding group of lamps will emit light to indicate different working states, the body will emit indicator light, the entire body will present the indicator color, the luminous area is large, and the indication is clear; the defect of the prior art that an indicator light needs to be set on the device using the control component is overcome.

Description

A kind of knob

Technical field

The utility model relates to a kind of knob.

Background technology

Present prior art, a kind of knob comprises body, and there is the annular housing of an after-opening rear end of body, and there is a joint pin at the annular housing center, and spliced eye is arranged on the joint pin.During use, knob cooperates with control assembly, when the knob rotation, during the operation control assembly, uses on the device of this control assembly, and other establishes pilot lamp.Existing problems: use inconvenience, the pilot lamp fermentation is long-pending little.

Summary of the invention

The purpose of this utility model is: a kind of knob is provided, and it need not establish pilot lamp in addition on the device that uses control assembly, easy to use, and light-emitting area is big, indicates clear.

The utility model is achieved in that a kind of knob, and it comprises body, and there is the annular housing of an after-opening rear end of body, and there is a joint pin at the annular housing center, and spliced eye is arranged on the joint pin, and its special character is: described body is made by transparent plastic material; Also comprise a lamp socket and be arranged at least three lamp groups on the lamp socket, there is a through hole at the center of lamp socket, and lamp socket is rounded evenly to be provided with at least three lamp groups; The through hole of lamp socket cooperates with joint pin, and lamp socket is fixed in the annular housing, and the lamp group is in the base plate and the annular housing between the lamp socket of annular housing.

Described a kind of knob, its special character is: in annular housing, the joint pin both sides, be symmetrically arranged with two support columns along diameter line, annular boss is arranged at the bottom of support column; Through hole both sides on the lamp socket, be symmetrically arranged with two fixed orifices along diameter line; Fixed orifice cooperates fixing with support column, annular boss supports lamp socket.

Described a kind of knob, its special character is: described lamp socket directly is fixed on the joint pin by through hole.

A kind of knob of the utility model, owing to adopt such structure, during the knob rotation, in different control positions, corresponding group lamp is luminous, indicates different duties, and body appears pilot light, whole body presents indicator light colors, and light-emitting area is big, indicates clear; Overcome in the prior art, needed the defective of on the device that uses this control assembly, establishing pilot lamp in addition.
