The invention relates to the technical field of construction, and discloses a detachable self-locking sleeve internal connecting device. The detachable self-locking sleeve internal connecting device comprises a sleeve, wherein a slurry inlet is formed in the left side of the top of the sleeve, a slurry outlet is formed in the right side of the top of the sleeve, and sealing rings are movably connected to the left side and the right side of the interior of the sleeve. According to the detachable self-locking sleeve internal connecting device, through cooperative use of a steel bar, the sleeve, a detachable self-locking type reinforcing device, a side tip compression spring and a spring, when the steel bar is inserted into the sleeve, rib lines of the ribbed steel bar extrude the side tip compression spring to compress the spring through external force, after the rib lines of the steel bar pass, through the elastic force of the spring, the spring pushes the side tip compression spring to move in the direction of the steel bar to tightly fix the steel bar, and therefore tight positioning and locking of the steel bar are achieved; and meanwhile, the device is easy to operate, the labor cost is saved, and the safety problem caused by the fact that the steel bar in the sleeve is not uniform is avoided through the locked sleeve.

本发明涉及施工技术领域，且公开了一种可拆卸自锁套筒内部连接装置，包括套筒，所述套筒的顶部左侧开设有进浆口，所述套筒的顶部右侧开设有出浆口，所述套筒内部的左、右侧均活动连接有密封圈，该可拆卸自锁套筒内部连接装置，通过钢筋、套筒、可拆卸自锁式加固器、侧尖头压缩弹簧、弹簧、配合使用，使钢筋插入套筒的内部时，然后通过外力使带肋钢筋的肋纹挤压侧尖头压缩弹簧压缩弹簧，当钢筋的肋纹通过后，通过弹簧的弹力，使弹簧推动侧尖头压缩弹簧向钢筋的方向运动紧密的固定住钢筋，从而达到了对钢筋的紧密的定位与锁定，同时也使装置操作简单、节省人工成本，锁定后的套筒避免了套筒内部钢筋不齐而导致的安全问题。
