Description
Technical field
The utility model relates to a kind of knob, the knob that uses on specifically a kind of household electrical appliance.
Background technology
At present, being used for the knob of control time, temperature on the household electrical appliance generally all is installed on the timer, because knob protrudes outside control panel, not only increased the overall volume of household electrical appliance, also be not easy to cleaning, owing to touch knob mistakenly, cause the change of user mode and unnecessary startup easily under the more important thing is in working order.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, and a kind of simple in structure, safe and reliable elastic press type knob is provided, and push-turn key and locking in the time of are in working order rotated behind the ejection knob when needing to adjust state of a control.
The purpose of this utility model is achieved in that it comprises gland, spring, sliding sleeve, slide bar, fibula, and described sliding sleeve is fixed on the gland; Described slide bar places sliding sleeve to be loose fit, and this slide bar can come and go with respect to sliding sleeve and move; Described slide bar is provided with guide groove, is provided with the grab of locking fibula in the guide groove; One end of described fibula places guide groove, and the other end and sliding sleeve flexibly connect; One end of described spring withstands on the gland, and the other end withstands slide bar; The end of described slide bar is provided with the axis hole that is installed on the timer rotation axis.
Be provided with between described slide bar and the sliding sleeve and make slide bar with respect to round groove and the fin that moves of sliding sleeve, fin places and is loose fit in the groove; The bottom of described guide groove is provided with the guiding step of promising fibula guiding; Be provided with the positive stop lug boss of restriction slide bar return between described slide bar and the sliding sleeve; Be provided with the positive stop lug boss of restriction slide bar return in the described guide groove.
Good effect of the present utility model is: push-turn key can prevent that the people from mistake occurring for causing state of a control during (1) work, and is simple in structure, safe and reliable; (2) can be directly installed on the rotation axis of household electrical appliance timer, need not change existing control panel and timer construction; (3) reduced the overall volume of household electrical appliance.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the conspectus that the utility model embodiment guide barrel construction and fibula move in guide groove.
Fig. 3 is the utility model embodiment shift sleeve structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Among the figure, be provided with the 11 and spring reference columns 3 of the protruding seat of interior sky that are used for fixing sliding sleeve 2 on the gland 1, when slide bar fin 12 when sliding sleeve groove 16 inserts sliding sleeves 2, spring 4 just in time withstands in the fixing hole 5 of slide bar end, the axis hole 9 of slide bar 8 other ends is installed on the rotation axis of timer.If the initial condition of knob is the ejection state, fibula 10 moves to the B point from the A point and stops in guide groove 13 when push-turn key, and the back fibula 10 of loosing one's grip moves to C point back and blocked and lock by grab 15 under the effect of spring force, and knob is in the state of being pressed at this moment.Fibula 10 moves to the D point and stops during push-turn key once more, the back fibula 10 of loosing one's grip moves to the A point under the effect of spring force, limited the return of slide bar 8 when slide bar positive stop lug boss 6 is run into sliding sleeve positive stop lug boss 7, so fibula 10 stops when moving to the A point, this moment, knob was in the ejection state.Owing to the guide groove bottom is provided with guiding step 14, cause fibula 10 on the circuit that is provided with the guiding step, can only to be blocked by protruding hook 15 exactly to moving also by folk prescription.
