Abstract

The utility model relates to a spring out mechanism for a charging pin, which comprises a casing and a pin, wherein, the pin is hinged in the casing; an open groove suitable for the rolling out of the pin is arranged on the casing. The utility model is characterized in that a positioning tooth and a torsional spring are arranged on a rotating shaft of the pin; the positioning tooth is cooperated with a buckling foot which is arranged above the pin and hinged with the casing as well; the buckling foot is downwards abutted with a pressure spring and upwards abutted with a press button; the upper end of the button extends out of the casing; the middle part is provided with a spacing piece. The utility model overcomes the defects that a pull-out or a wrench-out charging pin needs the simultaneous operation of two hands, and the use is inconvenient; the utility model has the advantages of simple structure, convenient and quick operation and reliable performance and is suitable to be popularized and applied in various small appliances.

Description

The charge pin ejecting mechanism

The utility model relates to a kind of charge pin ejecting mechanism.

The pin mode that goes out of the charge pin at random of small household appliances such as existing electric shaver is divided into push type and the formula of pulling out, and it is more stiff to use, generally all need with the hands to operate, and certain meaning, its use is very inconvenient.

The purpose of this utility model is the above-mentioned defective that overcomes prior art, thus provide a kind of simple in structure, go out pin speed charge pin ejecting mechanism fast, convenient to use.

The utility model comprises housing and pin, pin is hinged in the housing, housing is provided with and adapts to the open slot that pin produces, in the rotating shaft of pin, be provided with positioning tooth and torsion spring, positioning tooth matches with the button pin that housing is hinged equally with the pin top, and the button underfooting compresses spring, upward by button, stretch out outside the housing upper end of button, and the button middle part is provided with banking stop.

The button pin is " " shape, and an end of torsion spring is fixed on the pin, and the other end is fixed on the button pin.

The inner walls of opening trough rim is provided with locating piece and matches with positioning tooth.

Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model charged state.

As shown in the figure, the utility model comprises housing 1 and pin 2, pin 2 is hinged in the housing 1 by rotating shaft 3, and housing 1 is provided with and adapts to the open slot 10 that pin 2 produces, and is provided with in the rotating shaft 3 of pin 2 and decides tooth 4 and torsion spring 5, positioning tooth 4 matches with the button pin 6 that housing 1 is hinged equally with pin 2 tops, button pin 6 is " " shape, compresses spring 7 under it, upward by button 8, stretch out outside the housing 1 upper end of button 8, and the middle part is provided with banking stop 9.One end of torsion spring 5 is fixed on the pin 2, and the other end is fixed on the button pin 6.Being provided with locating piece 11 on housing 1 inwall on open slot 10 limits matches with positioning tooth 4.During charging, press the button 8, button pin 6 rotates counterclockwise, and the positioning tooth 4 in its end and the pin rotating shaft 3 is separated, and the pin 2 that loses the location ejects from open slot 10 under the effect of torsion spring 5, and by the cooperate location of locating piece 11 with positioning tooth 4.And button 8 resets under the effect of stage clip 7 and banking stop 9.After charging finishes, touch pin 2 and clockwise rotate, the locking that interlocks of positioning tooth 4 and button pin 6, charge pin returns to normal condition.

The utility model is by above-mentioned specific design, has the advantage of easy to operate, dependable performance simple in structure, The rhythm of life that meets the modern is adapted at applying in all kinds of small household appliances.
