Key string for closed-hole type lock cylinders
The invention discloses a key string for closed-hole type lock cylinders. The key string comprises an operation head, a rotating shaft, a protection cylinder, a mounting cylinder, a blocking piece, an adjusting cylinder and a fixing block; a plurality of push rods are arranged on the mounting cylinder, the front ends of the push rods extend out of the mounting cylinder, the tail of the mounting cylinder is in a chuck shape, a plurality of fan-shaped protrusions are arranged on the blocking piece, and the fan-shaped protrusions are clamped into clamping grooves in the tail portion of the mounting cylinder, so that the blocking piece and the mounting cylinder are connected into a whole; a plurality of stop levers are arranged in the adjusting cylinder, the number of the stop levers is integral multiples of that of the push rods, and the stop levers are used for stopping the axial movement of the push rods so as to limit the axial movement distances of the push rods; and a plurality of inserting openings are formed in the outer circle of the front end of the adjusting cylinder, and clamping blocks of a claw disc at the tail of the mounting cylinder are inserted into the inserting openings correspondingly. The key string can simultaneously unlock a plurality of lock cylinders, is more convenient to carry by a user, and avoids the additional cost increased by arranging a plurality of keys.
本发明公开了一种闭孔式锁芯的钥匙串，包括操作头、转动轴、保护筒、安装筒、阻挡片、调节筒和固定块，所述安装筒上设置有若干个推杆，所述推杆的前端伸出安装筒外，所述安装筒的尾部呈卡盘状，所述阻挡片上设置有若干个扇形凸起，各个扇形凸起分别卡入到安装筒尾部的卡槽内将阻挡片和安装筒连接成整体；所述调节筒内设置有若干个挡杆，所述挡杆的数量为推杆的整数倍，所述挡杆用于阻挡推杆轴向运动以限制推杆的轴向运动距离；所述调节筒的前端外圆上设置有若干个插接口，所述安装筒尾部爪盘的各个卡接块分别插接到各个插接口内。本钥匙串可同时开启多个锁芯，用户携带更加方便，同时避免了配备多个钥匙而增加的额外成本。
