[0001] The utility model relates to the technical field of copiers, in particular to an iron shaft for copiers. Background Art
[0002] With the development of science and technology, copiers have become one of the essential equipment in office, study and other occasions. The function and performance requirements of copiers are constantly improving, and the structure and working principle of copiers are becoming increasingly complex. Among them, the iron shaft of the copier is one of the key components, which is used to support and transmit movement to ensure the normal operation of the copier.
[0003] In order to improve the performance and stability of copiers, the requirements for the manufacturing and processing accuracy of the copier iron shaft are becoming higher and higher. At the same time, in order to adapt to different models and brands of copiers, the shape and size of the copier iron shaft also need to be customized and adjusted.
[0004] Traditional copier iron shafts are usually made of metal materials, which have certain strength and durability. However, with the continuous development of copier technology and the improvement of copier performance requirements, the manufacturing and processing technology of copier iron shafts is also constantly improving and perfecting.
[0005] The existing copier uses an iron shaft to support the drum core when in use. However, when the drum core needs to be disassembled, one end of the iron shaft needs to be tilted up and the drum core and the iron shaft need to be rotated and separated. Due to the long length of the iron shaft and the drum core, it is difficult to disassemble the drum core and it is not easy to control.
[0006] Therefore, it is necessary to provide a kind of copier iron shaft to solve the above-mentioned technical problems. Utility Model Content

[0009] By adopting the above technical solution, the first bone shaft and the second bone shaft can be disassembled from both ends of the drum core, making it more convenient and stable to disassemble the drum core.
[0010] The utility model is further configured as follows: a positioning groove is provided on a side wall of the second bone shaft close to the spring, and an end of the spring away from the first bone shaft is arranged inside the installation groove.
[0011] By adopting the above technical solution, the spring is positioned through the installation groove and the limiting rod to avoid misaligned contact between the spring and the second bone axis, which would cause a loose connection between the first bone axis and the second bone axis.
[0012] The utility model is further configured as follows: bearings are provided at the ends of the first bone axis and the second bone axis that are away from each other.
[0013] By adopting the above technical solution, the bearing can ensure that the first bone shaft and the second bone shaft remain stable during rotation, reduce friction and wear, and thus improve the efficiency and life of the copier.
[0014] The utility model is further configured as follows: a plurality of locking grooves are provided at the ends of the first bone axis and the second bone axis that are away from each other, a buckle is provided inside the locking groove, a plurality of teeth are fixedly connected to the inner wall of the buckle, and the teeth are snap-fitted and installed inside the locking groove.
[0015] By adopting the above technical solution, the bearing is locked and limited by the mutual engagement of the buckle and the locking groove, and the position of the bearing is adjusted by adjusting the position of the buckle.
[0016] The utility model is further configured as follows: anti-slip grooves are provided at the ends of the first bone axis and the second bone axis that are away from each other.
[0017] By adopting the above technical solution, the friction between the surfaces of the first bone shaft and the second bone shaft is increased by the anti-slip grooves, so that the rotation is facilitated.
[0018] In summary, the utility model has the following beneficial effects: when installing and separating the drum core and the iron elbow of the copier, the first bone shaft is inserted into one end of the drum core, and then the second bone shaft is inserted from the other end of the drum core, and the second bone shaft is continuously pushed into the drum core, so that the connecting ring is inserted into the connecting groove, and the card block on the side wall of the connecting groove enters the card groove on the inner wall of the connecting ring. The card groove is set as an L-shaped card groove. When the connecting ring is fully inserted into the connecting groove, the card block reaches the corner of the card groove, and then the first bone shaft is fixed, and the second bone shaft is rotated so that the card block enters the interior of the card groove. When the connecting ring and the connecting groove are engaged with each other, the limit rod is inserted into the interior of the slot, and the second bone shaft is inserted into the interior of the slot. As the two bone shafts continue to move forward, the compression degree of the spring by the second bone shaft continues to deepen. After the block completely enters the slot, the spring is compressed to the maximum limit. At this time, the spring elastic force is the largest, and the first bone shaft is supported by the spring elastic force, so that a pre-tightening force is added between the block and the slot, making the connection between the first bone shaft and the second bone shaft tighter and firmer. When disassembling the drum core, fix the first bone shaft, and then push the second bone shaft in the direction of the first bone shaft to offset the pre-tightening force caused by the spring. The second bone shaft can be removed by rotating the second bone shaft. The first bone shaft and the second bone shaft can be removed from both ends of the drum core through this device, which makes it more convenient and stable to disassemble the drum core.
