Abstract

This utility model discloses one anti-jumping device for the second hand of watch. It includes second intermediate wheel, second wheel and second side spring. The second intermediate wheel is engaged with the second wheel. One end of the second side spring is clamped onto the shaft neck of the second wheel and the other end is fixed onto the clamping board. This mechanism has such advantages as simple structure, low manufacturing cost, effective prevention of second hand jumping and improvement of watch grade.

Description

Wrist-watch prevent jump second mechanism

Technical field

The utility model relates to a kind of wrist-watch parts, and what particularly relate to a kind of wrist-watch prevents jump second mechanism.

Background technology

In general, wrist-watch is in operational process, and an idle wheel driving second second wheel turns clockwise, and second wheel drives second hand rotation synchronously thereupon, thereby refers to second on dial plate.But, when the second of existing general wristwatch, the idle wheel gear teeth were meshed with the second wheel gear teeth, there is certain interval between the two gear teeth, therefore, second wheel revolution under the driving of idle wheel second is crossed gear teeth, take place once small intermittence in the capital, causes the shake of second hand generating period in rotary course, promptly usually said jump second phenomenon.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the shortcoming of the second hand jump second that existing general wristwatch exists, and what a kind of wrist-watch was provided prevents jump second mechanism.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the jump second mechanism that prevents of the utility model wrist-watch comprises: second idle wheel, second wheel and second side spring; Idle wheel was meshed with second wheel in described second; On the one distolateral diameter of axle position that is pressed in second wheel of described second side spring, its other end is fixed on the clamping plate.

The beneficial effects of the utility model are: simple in structure, low cost of manufacture can prevent the generation of second hand jump second phenomenon effectively, improves the class of wrist-watch product.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

As shown in Figure 1, the jump second mechanism that prevents of the utility model wrist-watch comprises: second idle wheel 1, second wheel 2 and second side spring 3; Idle wheel 1 was meshed with second wheel 2 in described second; On the one distolateral diameter of axle position that is pressed in second wheel 2 of described second side spring 3, its other end is fixed on the clamping plate (not shown).

The principle of work that prevents jump second mechanism to the utility model wrist-watch is illustrated below:

As shown in Figure 4, wrist-watch is in operational process, and second, idle wheel 3 driving second wheels 2 turned clockwise, and second wheel 2 drives the rotation synchronously thereupon of second hand (not shown)s, thereby refers to second on dial plate.Because on the distolateral diameter of axle position that is pressed in second wheel 2 of second side spring 3, thereby the centre distance between second wheel 2 and second idle wheel 3 is reduced slightly, make the sideshake between the second wheel 2 and second idle wheel 3 intermeshing gear teeth diminish, second, idle wheel 3 drove second wheel 2 rotations in uniform and stable ground more, reached the purpose that prevents the second hand jump second.

Otherwise, as shown in Figure 3, if there is not second effect of side spring 3, sideshake between the second wheel 2 and second idle wheel 3 intermeshing gear teeth is bigger, second wheel 2 revolution under idle wheel 3 driving second is crossed gear teeth, all can take place once small intermittence, causes second hand to produce the jump second phenomenon.

It is worthy of note that the jump second mechanism that prevents of the utility model wrist-watch both can be used for mechanical watch, also can be used for indicating quartz electronic wristwatch.

Claims

A wrist-watch prevent jump second mechanism, it is characterized in that: comprising: second idle wheel (1), second wheel (2) and second side spring (3); Described idle wheel second (1) is meshed with second wheel (2); On the one distolateral diameter of axle position that is pressed in second wheel (2) of described second side spring (3), its other end is fixed on the clamping plate.
