[0002] The sling aluminum sleeve is a kind of pipe connection material for wire rope binding, mainly used for the pressing and threading of the wire rope end ring. The sling aluminum sleeve is a tubular fitting made of pure aluminum, used to fix the heads at both ends of the wire rope to ensure the stability and safety of the wire rope during hoisting operations. It is mainly applied to the pressing of wire rope rigging and is widely used in the hoisting and lifting fields, such as bridge construction, port loading and unloading, heavy object hoisting and other scenarios.
[0003] In the prior art, the sling aluminum sleeve can be divided into two types: seamless aluminum sleeve and slotted aluminum sleeve. The seamless aluminum sleeve is formed by core rod extrusion, with high quality and good safety performance; the slotted aluminum sleeve is formed by extrusion welding, with lower cost but poor safety performance. When installing and using the sling aluminum sleeve, it is fixed to the steel cable by workers hammering it into the steel cable.
[0004] However, the traditional sling aluminum sleeve lacks a self-locking structure when encountering unexpected situations during use. When the sling is subjected to excessive pulling force, it is prone to accidental detachment or loosening without manual intervention, and it is not convenient for disassembly, installation and fixation during the maintenance of the sling, which increases the labor cost and is time-consuming and laborious. Therefore, the utility model proposes a sling locking aluminum sleeve with a self-locking mechanism to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to provide a sling locking aluminum sleeve with a self-locking mechanism to solve the problems raised in the above background technique.

[0007] A plurality of springs are fixed at the bottom end inside the placement groove, and the springs are evenly distributed in an array. The top of the spring is fixed with a movable ring, and four clamping rods are installed on the top of the movable ring. The four clamping rods are evenly distributed in an array on the top of the movable ring, and clamping blocks are fixed on the opposite inner surfaces of the top ends of the clamping rods.
[0008] Preferably, a cross groove is opened at the top of the aluminum sleeve main body, the cross groove is located at the top of the placement groove, and a fixed inclined block is fixedly installed inside the cross groove. The thickest part of the fixed inclined block is flush with the top surface of the inner wall of the cross groove and the upper surface of the aluminum sleeve main body.
[0009] Preferably, the side wall of the aluminum sleeve body is provided with hole grooves, which are evenly distributed on the side wall of the aluminum sleeve body. A convex part is fixed on the side wall of the movable ring, and the convex part is located inside the hole groove.
[0010] Preferably, a movable clamping sleeve is installed on the outer surface of the aluminum sleeve body. The movable clamping sleeve is located on the outer surface of the hole groove, and a long groove is provided on the outer surface of the movable clamping sleeve.
[0011] Preferably, a movable clamping plate is movably installed inside the long groove. A clamping groove is provided on the side wall of the long groove. A hinge is installed through the center of the movable clamping plate, and both ends of the hinge are located inside the clamping groove.
