[0059] The rotary head is a structure for facilitating manual rotation, fixedly installed at the other end of the screw rod 16, located at the outer end of the connecting cylinder 3. The operator drives the screw rod 16 to rotate by rotating the rotary head 17, and then drives the arc-shaped plate 15 in the connecting cylinder 3 to move up and down, thereby conveniently and quickly realizing the operation of installing, positioning and adjusting the position of the sleeve 4 and the connecting cylinder 3 to adapt to different sizes of the sleeve 4, and improving the convenience of chain wheel installation and use.

[0060] Usage instruction

[0061] The fan-shaped chain wheel disc one 1 and the fan-shaped chain wheel disc two 2 are combined to form a complete chain wheel disc, and the combination is not only convenient for transportation and installation, but also facilitates quick disassembly during later maintenance. The chain teeth 5 arranged regularly on the outer end surface of the chain wheel disc are the direct action points of power transmission, and the connecting cylinder 3 located in the center of the chain wheel disc surface and the sleeve 4 connected at the other end provide stable support and rotation basis for the chain wheel, ensuring smooth operation of the chain wheel. A plurality of installation grooves are opened at the outer end of the fan-shaped chain wheel disc one 1 and the fan-shaped chain wheel disc two 2, corresponding to the chain teeth 5 one by one. The U-shaped piece 6 at the bottom of the chain tooth 5 is cleverly sleeved at the outer end of the installation groove. Only by rotating the bolt one 8 into the threaded hole in the center of the surface of the U-shaped piece 6, the fastening connection of the chain tooth 5 and the chain wheel disc can be quickly completed, and the installation efficiency of the chain tooth is improved. When replacing the worn chain tooth, complex tools and operations are not required, and the replacement can be completed in a short time to ensure the normal work of the chain wheel. At the same time, the close cooperation of the U-shaped piece 6 and the installation groove and the fixation of the bolt one 8 make the chain tooth 5 accurately positioned during work, avoiding the influence of power transmission caused by shaking. The installation grooves two 12 on both sides of the surface of the fan-shaped chain wheel disc one 1 and the fan-shaped chain wheel disc two 2 are used to connect the connecting piece 13 in the installation grooves two 12 during installation. By rotating the bolt two 14 into the corresponding threaded holes on both sides of the surface of the connecting piece 13 and the bottom surface of the installation grooves two 12, the two fan-shaped chain wheel discs can be quickly and firmly spliced into a complete chain wheel disc. The fixing disc 9 at the front end of the connecting cylinder 3 is accurately installed in the installation groove one 7. The through holes arranged around the surface of the fixing disc 9 correspond to the threaded holes arranged around the inner bottom surface of the installation groove one 7. By sequentially inserting the fixing pin 10 through the through holes of the fixing disc 9 and the threaded holes of the installation groove one 7, and rotating the nut 11 on the outer end of the chain wheel disc, the stable connection of the connecting cylinder 3 and the chain wheel disc is realized, which not only ensures the connection strength, but also accurately limits the position of the connecting cylinder 3 on the chain wheel disc through the cooperation of the fixing pin 10 and the nut 11, so that the chain wheel always remains stable during high-speed rotation, avoiding operation failure caused by the deviation of the connecting cylinder. The arc-shaped plates 15 arranged around the inside of the connecting cylinder 3 are connected with the rotating head 17 through the screw rod 16. When the sleeve 4 needs to be installed, the operator only needs to rotate the rotating head 17, and the screw rod 16 drives the arc-shaped plate 15 to move up and down in the connecting cylinder 3. When the lower end of the arc-shaped plate 15 contacts and presses the inner wall of the sleeve 4, the anti-skid pattern at the lower end of the arc-shaped plate 15 increases the friction force with the inner wall of the sleeve 4, thereby realizing the quick installation and reliable positioning of the sleeve 4 and the connecting cylinder 3. It is worth mentioning that the position of the arc-shaped plate 15 can be flexibly adjusted by rotating the rotating head 17, so that the chain wheel can adapt to different sizes of the sleeve 4, greatly improving the versatility of the chain wheel.
