Abstract

本实用新型涉及一种定时器,该定时器的分度盘的槽孔中插设有绕中部枢轴转动的拨键,该拨键的外侧边下方具有与摆杆一端相吻合的缺口,底部开有的第一、第二定位槽,压板上设置有与第一、第二定位槽相配合的定位凸起,当拨键向分度盘外侧拨动时,拨键外侧边与摆杆一端相触碰,同时定位凸起位于第一定位槽中,而当拨键向分度盘中心侧拨动时,缺口对应于摆杆的一端,定位凸起则位于第二定位槽中。采用上述结构后,使得本实用新型既克服了定时销易丢失、操作不便的缺陷,同时又具有结构简单,操作手感好,整体感强的特点。再者,借助于轴向设置的螺钉,可以确保调时齿轮与时针轴之间可靠连接,从而避免了在生产和运输过程中出现的松动现象,可有效地提高定时器的使用性能。
The utility model relates to a timer. A dial key rotating around a middle pivot is inserted into the slotted hole of an index dial of the timer, a notch matched with one end of a swinging rod is arranged below the outer side of the dial key, a first positioning slot and a second positioning slot are formed at the bottom, and a positioning bulge matched with the first positioning slot and the second positioning slot is formed on a press plate. When the dial key is shifted towards the outer side of the index dial, the outer side of the dial key is in contact with one end of the swinging rod, andthe positioning bulge is positioned inside the first positioning slot; and when the dial key is shifted towards the center of the index dial, the notch corresponds to one end of the swinging rod, andthe positioning bulge is positioned inside the second positioning slot. By adopting the above structure, the timer overcomes the shortcoming that a timing pin is easily lost and is inconvenient to operate, and has the characteristics of simple structure, good operating handfeel and high integrity. By virtue of axially arranged bolts, the timer can ensure the reliable connection between a timing gear and an hour hand shaft, so as to avoid loose of the timing gear and the hour hand shaft during production and transportation and effectively improve the service performance of the timer.
