Abstract

The utility model relates to a rotary electronic clock and watch time adjusting switch which comprises a casing 6, a control circuit, a metal contact piece 5 of a switch-on circuit, a rotary disc 1, a gear 2 linked with the rotary disc 1, and a toggling block 3 which is toggled by the gear 2 to do linear motion back and forth, wherein, the toggling block 3 is limited and reset by an elastic medium 4; the metal contact piece 5 is arranged on the toggling block 3; the disc 1 rotates and drives the gear 2 to rotate; the gear 2 toggles the toggling block 3 to do linear motion back and forth; a control circuit is continuously switched on and switched off by the metal contact piece 5 along with the motion of the toggling block 3, which can reach the goal of adjusting time. If the disc 1 is rotated along two directions, bidirectional time adjusting can be realized.

Description

Rotary electronic clock and watch timing switch

The utility model relates to a kind of timing switch of electronic watch, particularly a kind of rotary electronic clock and watch timing switch.

Present common electronic watch timing switch, all form by elastic metallic contact and button, thereby pin or unclamp the elastic metallic contact by button and be switched on or switched off the purpose that control circuit reaches timing, but this timing switch is because work the time will pressed the elastic metallic contact, has used of a specified duration can to make the distortion of elastic metallic contact and can not normally use, and this timing switch can only unidirectional timing, when timing if accidentally surpassed, just must restart timing, operation bothers than the school.

The purpose of this utility model provides a kind of revolving electronic watch timing switch that can two-way timing, and the metal contact is not yielding, and easy to use, if careless timing has surpassed, as long as rotating circular disk back.

In order to achieve the above object, the utility model has adopted following technical scheme:

A kind of rotary electronic clock and watch timing switch comprises the metal contact 5 of housing 6, control circuit and connection circuit, also comprises rotating circular disk 1, stirs the straight-line back and forth shifting block 3 of work with the gear 2 of rotational circle 1 interlock and by gear 2; Shifting block 3 is subjected to the restriction of elastic medium 4 and resets; Metal contact 5 is contained on the shifting block 3.

Because adopt said structure, metal contact 5 is contained on the shifting block 3, disk 1 rotates, and driven gear 2 rotates, and gear 2 is stirred shifting block 3 and made rectilinear motion back and forth, and metal contact 5 just can reach the purpose of timing along with the motion of shifting block 3 constantly switches on and off control circuit.Two-way rotating circular disk 1 can be realized two-way timing.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the A-A cut-open view of Fig. 2;

Fig. 4 is illustrated B-B cut-open view.

A kind of rotary electronic clock and watch timing switch comprises the metal contact 5 of housing 6, control circuit and connection circuit, also comprises rotating circular disk 1, stirs the straight-line back and forth shifting block 3 of work with the gear 2 of rotating circular disk 1 interlock and by gear 2; Rotating circular disk 1 assembly is on housing 6; Gear 2 is located at the back side of disk 1 and affixed with rotating circular disk 1; Position corresponding to gear 2 is provided with a movable shifting block 3, and shifting block 3 is provided with a projection 7, and projection 7 is connected mutually with gear 2; Position corresponding to shifting block 3 on the housing 6 is provided with one " mouth " shape frame 9, and frame 9 surrounds shifting block 3, prevents that shifting block 3 from moving up and down; Between shifting block 3 and the frame 9 spring 4 is housed, helps shifting block 3 to reset; Metal contact 5 is contained on the shifting block 3; The front of rotating circular disk 1 is provided with a duck eye 8, is convenient for people to stir disk 1.

During use, only need rotating circular disk 1 driven gear 2 to rotate, gear 2 is stirred projection 7 and shifting block 3 moving linearly back and forth, and the metal contact 5 on the shifting block 3 is also followed shifting block 3 and moved around, thereby reaches the purpose of two-way timing.
