Description

Technical Field

[0001] The utility model relates to the technical field of a copier drive shaft, and more specifically, to a copier drive shaft which is easy to replace. Background Art

[0002] A copier is a device that can make enlarged or reduced copies of written, drawn or printed originals. It has a fast copying speed and is easy to operate. The main difference between it and traditional lead type printing, wax paper mimeographing, offset printing, etc. is that it does not require other intermediate means such as plate making, but can obtain copies directly from the original. It is a common office equipment.

[0003] At present, the drive shaft of the copier is an important mechanical component inside the copier. Its function is to transmit the power of the motor to other parts of the copier to realize functions such as paper transportation and roller rotation.

[0004] However, when a problem occurs in the copier and the drive shaft is replaced, if the drive shaft is not replaced properly, problems such as paper jamming, poor printing quality, paper stacking, multiple pages of paper being fed at one time, and inability to scan or fax may occur, which not only causes certain damage to the copier, but also wastes time in replacing the drive shaft. Therefore, a copier drive shaft that is easy to replace is proposed to improve the existing problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide a copier drive shaft that is easy to replace.

[0007] Among them, the transmission connecting rod part includes a first transmission connecting rod, and a second transmission connecting rod is arranged at an end of the first transmission connecting rod away from the driving shaft head. The second transmission connecting rod and the first transmission connecting rod are both arranged as cylindrical structures and are coaxially arranged, and a first annular groove is arranged between the second transmission connecting rod and the first transmission connecting rod.

[0008] The driving shaft head portion comprises a driving head connecting rod, and a driving head is arranged at one end of the driving head connecting rod away from the transmission connecting rod portion.

[0009] The utility model is further configured as follows: the second transmission connecting rod includes a first fixed rod, a second fixed rod is arranged at one end of the first fixed rod away from the first annular groove, the second fixed rod and the first fixed rod are both configured as cylindrical structures and are coaxially arranged, and a second annular groove is arranged between the first fixed rod and the second fixed rod.

[0010] By adopting the above technical solution, the first annular groove facilitates the installation of the drive shaft, and can allow the drive shaft to be stably installed on the copier when replacing the copier drive shaft; the setting of the second annular groove allows the drive shaft to highlight the connection position during replacement and makes it easier to find the card slot position during replacement, which is suitable for the structure of the copier.

[0011] The utility model is further configured as follows: a connecting rod seat is arranged at one end of the second fixing rod away from the second annular groove, the connecting rod seat is arranged as a cylindrical structure, and the connecting rod seat is coaxially connected to the second fixing rod.

[0012] By adopting the above technical solution, rounded corners are provided on the connecting rod seat to facilitate the insertion and removal of the drive shaft. The connecting rod seat is configured as a cylindrical structure and is coaxially connected to the second fixed rod. The coaxially arranged structure is faster when the drive shaft is removed as a whole, which facilitates the replacement of the drive shaft.

[0013] The utility model is further configured as follows: a first connecting rod groove is opened on the side wall of the first fixing rod along the second annular groove position toward the first annular groove, the shape of the first connecting rod groove is set to be L-shaped, and a second connecting rod groove is opened on the side wall of the second fixing rod along the second annular groove position toward the connecting rod seat.

[0014] By adopting the above technical solution, the first connecting rod groove and the second connecting rod groove are arranged in the same horizontal plane, and the overall groove faces the same direction. A guide groove is set for the installation of the drive shaft, which has a guiding function. When the copier replaces the drive shaft, it is more directional and convenient to replace the copier drive shaft.

[0015] The utility model is further configured as follows: a driving head connecting rod is arranged at one end of the first transmission connecting rod away from the first annular groove, the driving head connecting rod is arranged as a rectangular structure, the driving head connecting rod is connected to the first transmission connecting rod, and the diameter of the driving head connecting rod is smaller than the diameter of the first transmission connecting rod.

[0016] The utility model is further configured as follows: a driving head is arranged at one end of the driving head connecting rod away from the first transmission connecting rod, the driving head is arranged as a prism structure, and the upper bottom surface of the driving head is arranged away from the driving head connecting rod.

[0017] By adopting the above technical solution, the drive head connecting rod and the drive head are integrally configured as a latch mechanism, which is convenient for fixing the drive shaft. At the same time, when the drive shaft is replaced, it is also convenient to plug and unplug the drive shaft, which provides convenience for replacing the drive shaft.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. The first annular groove is arranged around the side wall of the driving shaft, which can be adapted to the structure on the copier, thereby achieving the purpose of fixing the driving shaft when installing the driving shaft.

[0020] 2. The first connecting rod groove and the second connecting rod groove are combined to form a guide groove, which has a guiding effect when the drive shaft is installed, so as to achieve the purpose of quickly identifying the installation direction of the drive shaft and quickly replacing the drive shaft.

[0021] 3. The latch formed by the combination of the drive head connecting rod and the drive head facilitates the insertion and removal of the drive shaft when installing it, thereby achieving the purpose of fixing the drive shaft when actually replacing the drive shaft.
