播放器定位装置

Player positioning device

Abstract

本实用新型涉及一种播放器定位装置。该播放器定位装置,包括机盒,连接在机盒上的滑盖,机盒内设有定位机构,滑盖内面设有与定位机构配合运动的滑动机构。定位机构由滑盖打开到极限位置时垂直于机盒底面设置带有弹性定位构件的螺柱组成。滑动机构由滑盖打开所移动到极限位置时的滑盖内面对应滚珠的凹坑、该凹坑连通滑盖从闭合到打开过程中的运动轨迹所成型的导槽组成;当滑盖从打开向闭合过渡沿导槽运动时,滑盖向下压迫滚珠,弹簧压缩;待滑盖闭合到位时,定位机构的滚珠在弹簧的弹力作用下反弹,滚珠球面与滑盖底面的凹坑嵌合。该播放器定位装置通过定位机构滚珠球面利用弹簧的弹力与滑盖底面滑动机构的凹坑嵌合,使滑盖牢固地与机盒定位。
The utility model relates to a player positioning device which comprises a case and a sliding cover connected onto the case, wherein a positioning mechanism is arranged in the case, and a sliding mechanism matched with the positioning mechanism in motion is arranged on the inner surface of the sliding cover. The positioning mechanism is composed of bolts which are provided with elastic positioning members and perpendicular to the bottom surface of the case when the sliding cover is opened to the extreme position. The sliding mechanism is composed of pits and guide grooves, wherein the pits correspond to roll balls and are arranged on the inner surface of the sliding cover when the sliding cover is opened and moves to the extreme position, and the guide grooves are formed by communicating the pits and motion tracks generated during the sliding cover is closed and opened. When the sliding cover move along the guide grooves in transition from being opened to being closed, the sliding cover downwards presses the roll balls and a spring is compressed. When the sliding cover is closed in place, the roll balls of the positioning mechanism rebound under elastic force effect of the spring, and spherical surfaces of the roll balls of the positioning mechanism are meshed with the pits on the bottom surface of the sliding cover by aid of the elastic force of the spring, so that the sliding cover and the case are firmly positioned.
