Abstract

The utility model relates to a hand moving device of a miniature quartz clock movement, which is composed of a hand moving gear train and a limiting rod. The hand moving gear train comprises a hand moving wheel, a middle wheel and a swing arm. The hand moving wheel, the middle wheel and a setting wheel are arranged on a same plane. A hand moving gear can be automatically disengaged with the setting wheel. The utility model has the advantages that the clock movement is light and small, the moving resistance is little, and the stability is raised.

Description

A kind of miniature quartz clock movement pointer setting device

The utility model belongs to crystal clock manufacturing technology field, especially refers to a kind of pointer setting device of quartz clock movement.

At present, quartz clock movement just develops towards the direction of microminiaturization, and thickness is thick partially, movement layouts is unreasonable but also exist, and is assembled into defectives such as the clock volume is bigger than normal, makes the miniature quartz clock become clock also in a large amount of timepiece movements, characteristics that manufacturing cost is high used.When not dialling the needle-like attitude for pointer setting device is in, the engagement of discord third wheel, reduce energy consumption, 3 employings of (accompanying drawing 1) transmission wheel move axially mode and separate with third wheel 12, when dialling pin,, and easily cause clasp 2 wearing and tearing because inconvenience is used in pull bar 1 tension and compression action, cause the tension and compression action dumb, influence regularity oftimekeeping.

It is convenient, flexible that the purpose of this utility model provides a kind of action, can reduce resistance when walking, and improves the pointer setting device of regularity oftimekeeping.

The technical solution of the utility model is such: on the basis of existing quartz clock movement structure a special pointer setting device is set, pointer setting device is made of with limited post 9 transmission wheel system, transmission wheel system contains transmission wheel 4, breast wheel 5, swing arm 6, transmission wheel 4 is in the same plane with breast wheel 5, and a limited post 9 in position is set.

When being in when dialling the needle-like attitude, transmission wheel 4 clockwise rotates, drive swing arm 6 and be flapped toward third wheel 8, breast wheel 5 beginnings this moment and third wheel 8 engagements, because breast wheel 5 rotates counterclockwise, drive swing arm 6 and third wheel 8 correct engagement, limited post 9 can prevent the latch phenomenon, breast wheel 5 promptly under the promotion of dialling the needle shaft tooth, drives third wheel 8 with timing, minute hand.When being in when not dialling the needle-like attitude, third wheel 8 rotates as usual, promotes breast wheel 5 dialling on the needle shaft 10 because swing arm 6 is kinks, so breast wheel 5 drive when rotating swing arm 6 gradually with third wheel 8 drop out of gears, remove transmission wheel system and be added in load on the third wheel 8.

After having adopted above structure, make quartz clock movement when not dialling the needle-like attitude, dial the automatic and third wheel drop out of gear of pin gear system energy, reduced resistance when walking, improved regularity oftimekeeping, thereby can dwindle the size of battery, the size of corresponding movement is also dwindled.

Existing accompanying drawings is as follows:

Fig. 1. rod-pulling type pointer setting device structural representation.

Fig. 2. the utility model quartz clock movement planar structure synoptic diagram.

Fig. 3. the utility model quartz clock movement is not dialled needle-like attitude structural representation.

Fig. 4. the utility model quartz clock movement is dialled needle-like attitude structural representation.

Referring to Fig. 2-4, transmission wheel system is made of transmission wheel 4, swing arm 6, breast wheel 5, and what be meshed with breast wheel 5 is third wheel 8.When being in when dialling the needle-like attitude, transmission wheel 4 clockwise rotates, and transmission wheel 4 drives swing arms 6.Because breast wheel 5 rotates counterclockwise, drive swing arm 6 and be flapped toward third wheel 8, lean against on the limited post 9 until swing arm 6, breast wheel 5 and third wheel 8 correct engagement, breast wheel 5 promptly under the effect of transmission wheel tooth, drive third wheel 8 with timing, minute hand.When not dialling pin, third wheel 8 rotates as usual, breast wheel 5 drive swing arms 6 gradually with third wheel 8 drop out of gears, remove transmission wheel system and be added in load on the third wheel 8.

Claims

1. miniature quartz clock movement pointer setting device, it is characterized in that pointer setting device is made of with limited post (9) transmission wheel system, transmission wheel system comprises: transmission wheel (4), breast wheel (5), swing arm (6), and transmission wheel (4), breast wheel (5) are positioned at same plane with third wheel (8), swing arm (6) kink is in dialling on the needle shaft (10), appropriate location when breast wheel (5) and third wheel (8) correct engagement is provided with a limited post (9), and swing arm (6) is against on the limited post (9).
