Lock capable of interchanging lock handle left and right
The invention provides a lock capable of interchanging a lock handle left and right. The lock comprises a lock shell, the handle and a transmission shaft. The outer surface of the left end of the transmission shaft is sleeved with a first rolling bearing. A first sleeve is arranged on the upper side of the first rolling bearing. The end of the handle penetrates through a first through hole to be inserted into a blind hole. A limiting rod is arranged in a first limiting groove. The limiting rod penetrates through a round hole and is engaged into a first inner thread cylinder through a second outer thread. A first gear is fixed to the outer surface of the right end of a pin shaft. A second gear is installed on the ring-shaped side face of the transmission shaft. A middle gear is arranged onthe lower side of the second gear. The middle gear is engaged with the second gear. A round rod is fixed to the left end face of the middle gear. The outer surface of the left end of the round rod issleeved with a second rolling bearing. A second sleeve is arranged on the lower side of the second rolling bearing. A second limiting groove is formed in the upper side of the ring-shaped side face ofthe second sleeve. Compared with the prior art, the lock has the following beneficial effects that left and right interchanging of the handle is achieved, local replacement is achieved after the thread is damaged, and safety is improved.
本发明提供一种可让锁具手柄左右互换的锁具，包括锁壳、手柄以及传动轴，传动轴左端外表面套设第一滚动轴承，第一滚动轴承上侧设有第一套筒，手柄一端穿过第一通孔安插在盲孔内，第一限位槽内设有限位杆，限位杆穿过圆孔并通过第二外螺纹啮合在第一内螺纹筒内，销轴右端外表面固定第一齿轮，传动轴环形侧面上安装第二齿轮，第二齿轮下侧设有中间齿轮，中间齿轮与第二齿轮相啮合，且中间齿轮左端面固定圆杆，圆杆左端外表面套设第二滚动轴承，第二滚动轴承下侧设有第二套筒，第二套筒环形侧面上侧开设第二限位槽，与现有技术相比，本发明具有如下的有益效果：实现手柄的左右互换，还达到螺纹损坏后局部更换，提高安全性。
