Abstract
An unidirectional spring rotating handle for a timekeeper escapement displayer comprises a handle, a central shaft connected to the handle, one ratchet connected to the upper portion of the handle, a chain hinged to the ratchet wheel, a ratchet hinged to the ratchet, a ratchet releasing nail connected to the ratchet, an inclined fixing block hinged to the other end of the ratchet releasing nail, a detent spring connected to the other end of the ratchet, and an automatic releasing torsion spring arranged on the central shaft. When the handle is pulled anticlockwise to release the ratchet releasing nail from the constraint of the inclined fixing block, the detent spring pushes the ratchet to allow the ratchet press the ratchet wheel and be fixed on the shaft body of the ratchet wheel, so as to rotate simultaneously and to tighten the spring. In such a structure, unidirectional spring rotating handle provides automatic playback effect. The unidirectional spring rotating handle is simple in structure and convenient for use.
Description
Technical field
The utility model relates to fastener technical field, specifically clockwork spring single direction rotation handle for a kind of clock and watch escapement display device.
Background technology
The existing handle technology that contains ratchet and pawl all adopts manual operation, after the course of work finishes, must manual the handle that contains ratchet and pawl be taken away.
Utility model content
In order to address the above problem, the utility model provides a kind of clock and watch escapement display device clockwork spring single direction rotation handle.
A kind of clockwork spring single direction rotation handle for clock and watch escapement display device, comprise handle, it is characterized in that: also comprise central shaft, on central shaft, be connected with handle, the top of handle is connected with ratchet, ratchet be hinged with ratchet, ratchet is connected with ratchet and discharges nail, the other end that ratchet discharges nail is hinged with fixing skewback, and the other end of ratchet is connected with click spring, is also provided with automatic release torsion spring on central shaft.
Further, the number of described ratchet is 1.
Advantage of the present utility model:
1, can play the effect of automatic playback;
2, simple in structure, easy to use.
Brief description of the drawings
Fig. 1 is one-piece construction simplified schematic diagram of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated; Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1
As shown in Figure 1, clockwork spring single direction rotation handle for a kind of clock and watch escapement display device, comprises handle 1, also comprise central shaft 3, on central shaft 3, be connected with handle 1, the top of handle 1 is connected with ratchet 4, and the number of this ratchet 4 is 1, on ratchet 4, be hinged with chain, ratchet 4 be hinged with ratchet 5, ratchet 5 is connected with ratchet and discharges nail 6, the other end that ratchet discharges nail 6 is hinged with fixing skewback 7, the other end of ratchet 5 is connected with click spring 2, is also provided with automatic release torsion spring 8 on central shaft 3.
Stir counterclockwise handle 1, make ratchet discharge the restriction that nail 6 departs from fixing skewback 7, click spring 2 promotes ratchet 5, makes ratchet 5 pin ratchet 4, and the axis body being fixed on ratchet 4 together rotates, and plays the effect that turns tight clockwork spring.
Release lever 1, handle 1 is discharging self-return under torsion spring 8 effects automatically, and now under the restriction of fixing skewback 7, the covert nail of ratchet 6 tops, from ratchet 5, make ratchet 5 depart from ratchet 4, and the axis body being fixed on ratchet 4 can turn clockwise.
Adopt technique scheme, can play the effect of automatic playback, simple in structure, easy to use.
Claims (2)
