[0019] like Figure 1 As shown, the lifting mechanism of the present invention for a suspended assembly line is set between the inbound track 2 and the outbound track 3, and includes a lifting chain 4 and a sprocket assembly mounted on the frame 1.

[0020] like Figure 2As shown, the lifting chain 4 is composed of several chain plates 5, which are connected in sequence. Each chain plate 5 has a first arc-shaped edge 6 and a second arc-shaped edge 7. The first arc-shaped edge 6 of each chain plate 5 and the second arc-shaped edge 7 of the adjacent chain plate 5 form a space for accommodating the clothes hanger. The first arc-shaped edge 6 of the chain plate 5 is provided with a locking part 8 that can lock the clothes hanger. The clothes hanger is fixed between the adjacent chain plates 5 and moves with the lifting chain 4.

[0021] The chain plate 5 has a long side 9 and a short side 10 arranged opposite to each other. One end of the long side 9 of the chain plate 5 is provided with a connecting shaft 11, and the other end is provided with a connecting hole 12. This structure allows adjacent chain plates 5 to be connected in sequence through the connecting shaft 11 and the connecting hole 12, so that the first arc-shaped side 6 of each chain plate 5 and the second arc-shaped side 7 of the adjacent chain plate 5 can be fixed with a hanger, thereby improving the conveying efficiency of the lifting chain 4.

[0022] The long side 9 of the chain plate 5 has an outwardly extending convex surface 13, which can cooperate with the sprocket assembly. The inner side of the long side 9 of the chain plate 5 has a first groove 14, which can also cooperate with the sprocket assembly. An arc-shaped retaining edge 15 is formed between the convex surface 13 and the second arc-shaped side 7 of the chain plate 5, and a second groove 16 is formed on the inner side of the second arc-shaped side 7. When the chain plate 5 rotates around the connecting shaft 11, the first arc-shaped side 6 of the chain plate 5 abuts against the second arc-shaped side 7 of the adjacent chain plate 5, and the locking part 8 of the chain plate 5 can be inserted into the second groove 16 of the adjacent chain plate 5, restricting the rotation of the chain plate 5, preventing malfunctions during operation, and improving safety.

[0023] The sprocket assembly includes a first tensioner 17, a first main sprocket 18, a second tensioner 19, and a second main sprocket 20. The first main sprocket 18 is driven to rotate by a lifting motor. The lifting chain 4 passes through the first tensioner 17, the first main sprocket 18, the second tensioner 19, and the second main sprocket 20 in sequence.

[0024] like Figure 3 As shown, both the first tensioner 17 and the second tensioner 19 have inwardly recessed first grooves 21 and second grooves 22. The convex surface 13 of the chain plate 5 can abut against the first groove 21, and the chain plate 5 moves along the first groove 21. The short side 10 of the chain plate 5 can abut against the second groove 22, and the chain plate 5 moves along the second groove 22. Both the first main sprocket 18 and the second main sprocket 20 have protruding teeth 23, and both the first main sprocket 18 and the second main sprocket 20 have straight edges 24 distributed at equal intervals. The protruding teeth 23 can be inserted into the first groove 21 of the chain plate 5, and the convex surface 13 of the chain plate 5 fits against the straight edges 24, improving the accuracy of the parts fit.

[0025] The first main sprocket 18 and the first tensioning wheel 17 are located at the exit end of the entry track 2. When the lifting chain 4 passes the first tensioning wheel 17, the short side 10 of the chain plate 5 abuts against the second groove 22 of the first tensioning wheel 17, and the locking part 8 of the chain plate 5 is inserted into the second groove 16 of the adjacent chain plate 5. When the lifting chain 4 passes the first main sprocket 18, the protruding tooth 23 of the first main sprocket 18 is inserted into the first groove 14 of the chain plate 5, and the long side 9 of the chain plate 5 abuts against the straight edge 24 of the first main sprocket 18, and the locking part 8 of the chain plate 5 opens. The hanger enters the lifting chain 4 from the exit end of the entry track 2. As the lifting chain 4 continues to move, the locking part 8 of the chain plate 5 gradually closes, fixing the hanger between the adjacent chain plates 5, and the lifting chain 4 drives the hanger to move.

[0026] The second tensioning pulley 19 is located at the lowest working position. Below the second tensioning pulley 19 is a U-shaped first protective plate 25. The lifting chain 4 passes between the second tensioning pulley 19 and the first protective plate 25. The tension of the lifting chain 4 is adjusted by moving the position of the second tensioning pulley 19 up and down. When the lifting chain 4 passes the second tensioning pulley 19, the convex surface 13 of the chain plate 5 abuts against the first groove 21 of the first main sprocket 18, the locking part 8 of the chain plate 5 opens, and the hanger slides onto the first protective plate 25 for processing at the working position. The second arc-shaped edge 7 of the next chain plate 5 pushes the hanger to the exit end of the first protective plate 25, the locking part 8 of the chain plate 5 gradually closes, and the lifting chain 4 drives the hanger to continue moving.

[0027] The second main sprocket 20 is located at the exit end of the exit track 3. When the lifting chain 4 passes the second main sprocket 20, the protruding teeth 23 of the second main sprocket 20 insert into the first groove 14 of the chain plate 5, and the long side 9 of the chain plate 5 abuts against the straight edge 24 of the first main sprocket 18, thus opening the locking part 8 of the chain plate 5. The clothes hanger enters the inlet end of the exit track 3 via the lifting chain 4.

[0028] Furthermore, during the lifting process, due to the weight of the hanger, if the lifting chain 4 becomes loose without a protective plate, the locking part 8 of the chain plate 5 will fail to lock the hanger, causing the hanger to detach from the lifting chain 4 and interrupting the transport. Therefore, a second protective plate 26 is installed on the frame 1 between the second tensioning wheel 19 and the second main sprocket 20, placed at an angle. The second protective plate 26 serves to guide and fix the lifting chain 4, preventing the hanger from detaching from the lifting chain 4.

[0029] like Figure 4 As shown, the hub of the sprocket assembly includes a rim 27. The inner wall of the rim 27 is provided with first mounting rings 28 that are evenly distributed. The outer wall of the first mounting ring 28 is connected to a first connecting rod 29. The other end of the first connecting rod 29 is connected to a second mounting ring 30. The inner wall of the second mounting ring 30 is provided with second connecting rods 31 that are evenly distributed. The other end of the second connecting rod 31 is connected to the axle 32.

[0030] The hubs of the sprocket assembly all adopt a cut-radial structure design. Compared with ordinary hubs, the rim 27 is connected to the axle 32 sequentially through a first mounting ring 28, a first connecting rod 29, a second mounting ring 30, and a second connecting rod 31. This better resists the material cooling shrinkage deformation during injection molding, resulting in a smoother and more aesthetically pleasing injection-molded workpiece. Simultaneously, this design makes the sprocket assembly more evenly stressed, more stable during rotation, and extends the service life of the sprocket assembly.

[0031] The preferred embodiment of this utility model has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of this utility model.
