[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-Figure 3A lifting eye screw with an expansion self-locking structure comprises an expansion sleeve 1, a screw rod 2 is inserted inside the expansion sleeve 1, a plug hole is provided on the top of the screw rod 2, a positioning column 42 is inserted in the plug hole, a lifting eye 4 is fixedly arranged on the top of the positioning column 42, a mounting hole is provided on the outer wall of the screw rod 2, the mounting hole is communicated with the plug hole, threaded holes are evenly provided on the outer wall of the positioning column 42, a cross bolt 41 is rotatably arranged in the mounting hole, the cross bolt 41 is screwed with the threaded hole, after the cross bolt 41 is unscrewed, the lifting eye 4 connected with the positioning column 42 can be removed, so that different types of lifting eyes 4 can be quickly replaced according to actual hanging needs.
[0022] The outer wall of the expansion part of the expansion sleeve 1 is evenly fixed with a fixing cone 11, and the bottom of the screw rod 2 is fixed with an extrusion cone head 21, which is located below the expansion sleeve 1, and the lifting ring 4 is located above the screw rod 2. A magnetic block 43 is fixed at the bottom of the socket, and the magnetic block 43 and the bottom of the positioning column 42 are mutually adsorbed. The positioning column 42 can be stably fixed in the socket of the screw rod 2 through the adsorption of the magnetic block 43 on the positioning column 42 and the screw connection and fixation of the cross bolt 41, so that the lifting ring 4 can be stably fixed on the screw rod 2, thereby ensuring the hanging stability of the lifting ring 4. A gasket 3 is placed on the top of the expansion sleeve 1, and the gasket 3 is sleeved on the outer ring of the screw rod 2. A nut 31 is placed on the top of the gasket 3. The nut 31 is screwed on the outer ring of the screw rod 2, and the expansion sleeve 1 is inserted into the hole. The screw rod 2 can be driven to move outward by rotating the nut 31. At this time, the screw rod 2 drives the extrusion cone head 21 to move synchronously and squeeze the expansion part of the expansion sleeve 1. At this time, the expansion part of the expansion sleeve 1 will expand outward and drive the fixing cone 11 to embed into the inner wall of the hole, thereby completing the installation of the device. The cross bolt 41 is screwed into the threaded holes at different positions on the positioning column 42, so that the hanging angle of the lifting ring 4 can still be changed after the device is installed. The screw rod 2 and the extrusion cone head 21 are cut and formed in one piece, the expansion sleeve 1 and the fixing cone 11 are cut and formed in one piece, and the lifting ring 4 and the positioning column 42 are cut and formed in one piece.
[0023] Working principle: insert the expansion sleeve 1 into the hole, and rotate the nut 31 to drive the screw rod 2 to move outward. At this time, the screw rod 2 drives the extrusion cone head 21 to move synchronously and squeeze the expansion part of the expansion sleeve 1. At this time, the expansion part of the expansion sleeve 1 will expand outward and drive the fixing cone 11 to embed into the inner wall of the hole, so as to complete the installation of the device. Screw the cross bolt 41 into the threaded holes at different positions on the positioning column 42, so that after the device is installed, the hanging angle of the lifting ring 4 can still be changed. The positioning column 42 is adsorbed by the magnetic block 43 and the cross bolt 41 is screwed and fixed. The positioning column 42 can be stably fixed in the jack of the screw rod 2, so that the lifting ring 4 can be stably fixed on the screw rod 2, thereby ensuring the hanging stability of the lifting ring 4. After the cross bolt 41 is unscrewed, the lifting ring 4 connected to the positioning column 42 can be removed, so that different types of lifting rings 4 can be quickly replaced according to actual hanging needs.
