Description
Technical field
The present invention relates to a kind of handle box of laser printer.
Background technology
Laser printer is that a kind of electrofax principle that utilizes is formed at print media as the equipment on paper image, is usually made up of main frame and the handle box be removably installed in main frame; Wherein, handle box has box body, and form the photosensitive drums of electrostatic latent image and provide with the developer roll of this electrostatic latent image that develops on developer to photosensitive drums, photosensitive drums and developer roll are rotatably supported between the end walls of box body.Photosensitive drums has drum barrel and is installed on the revolving force transmitting assembly on an axial end of drum barrel, and drum barrel is made up of aluminum pipe and the photosensitive material layer be coated on outside aluminum pipe usually.When handle box is mounted in main frame, revolving force transmitting assembly should be convenient to and the driving shaft electrical connection in main frame, the revolving force of driving shaft is passed to drum barrel and other revolving parts, thus ensures the normal work of photosensitive drums and other revolving parts; After the carbon dust in handle box exhausts, need handle box to take out in main frame, more to renew handle box, in the process of taking out handle box, revolving force transmitting assembly should be convenient to depart from driving shaft connect under the effect of external force.
Publication No. is disclose a kind of handle box in the Chinese patent literature of CN102067042A, and its revolving force transmitting assembly is a unitor with sphere type universal joint.Enter main frame and the process of taking out in main frame, due to the effect of sphere type universal joint, the axis of unitor can produce an angle or conllinear with the axis of photosensitive drums at this cartridge, the connection being convenient to revolving force transmitting assembly and driving shaft connects with departing from; But this sphere type universal joint easily produces less desirable separation, particularly in transportation, this phenomenon more easily occurs, causes the propagation function of unitor to lose.
As the improvement to CN102067042A public technology scheme, the applicant is on October 30th, 2013 in publication date, publication No. is disclose a kind of handle box in the Chinese invention patent application of CN103376696A, this handle box has torque transmission 01 as shown in Figure 1, i.e. revolving force transmitting assembly, torque transmission 01 is by rotation force transmission element 011, axial limiting part 012, drum gear 013 and spring 014 are formed, drum gear 013 is formed with the uncovered container cavity 0131 be positioned on drum gear 013 1 axial end, another axial end of drum gear 013 is formed with the pilot hole 0133 be communicated with container cavity 0131.When handle box is mounted in printer host, the revolving force acceptance division with rotation force transmission element 011 connects by the revolving force applying unit being located at the driving shaft 02 on main frame.
As shown in Figure 2, revolving force applying unit is be formed at two edges on driving shaft 02 end to apply arm 021, two revolving forces perpendicular to the revolving force of the axially extended column of driving shaft 02 and apply arms 021 and be arranged symmetrically with about the axis centre of driving shaft 02; Rotation force transmission element 011 is made up of guide rod 0112 and the revolving force acceptance division 0111 that is positioned at guide rod 0112 axial end, and revolving force acceptance division 0111 is greater than guide rod 0112 along the lateral dimension of guide rod 0112; The lateral external wall of guide rod 0112 is provided with the output arm 01121 transversely extended outwardly for a pair; Revolving force acceptance division 0111 along guide rod 0112 axially back in the outer end wall of guide rod 0112, position in outer end wall along guide rod 0112 lateral runout outer end wall center, be provided with the revolving force receptor arm 01111 axially convexed to form along guide rod 0112 for a pair outwardly, revolving force acceptance division 0111 is positioned at the outer end wall between two revolving force receptor arm 01111 and forms a dome shape shrinkage pool 01112 along the axial indent of guide rod 0112.Drum gear 013 is roughly cylindrical, the inwall being parallel to drum gear 013 axis at container cavity 0131 is provided with the input arm 0132 extended towards its radial center for a pair, in the circumference of drum gear 013, output arm 01121 is in the position of input arm 0132 and input arm 0132 abutting contact.Another axial end of guide rod 0112 is successively through the through hole be formed on axial limiting part 012, and spring 014, container cavity 0131 arrive the pilot hole 0133 of clearance fit with it; Axial limiting part 012 coordinates with the opening end of container cavity 0131 and forms spacing away from drum gear 013 of revolving force acceptance division 0111.One end of spring 014 is resisted against on the side of output arm 01121 away from revolving force acceptance division 0111, on inside the bottom that the other end is resisted against container cavity 0131.
For the problem that the sphere type universal joint being used in technical scheme disclosed in CN102067042A transmitting revolving force easily departs from from drum gear, CN103376696A provides the torque transmission of handle box to adopt axial limiting part 012 to be limited in container cavity 0131 by the output arm 01121 be formed on guide rod 0112, and rotation force transmission element 011 is also fixed on drum gear 013.This make avoids the risk that rotation force transmission element 011 is separated with drum gear 013, thus ensures that whole torque transmission has good reliability and stability when transmitting revolving force.
But the handle box with this torque transmission exists swimmingly by the problem that it takes out in main frame, namely " can not block and time " phenomenon in actual use procedure.
For eliminating above-mentioned " card " phenomenon, solution can be designed from two aspects, on the one hand, Curve guide impeller be carried out to main frame, driving shaft by this main frame is designed to: when its free end is subject to pushing force vertically, and it can produce displacement towards the direction away from handle box vertically; On the other hand handle box is carried out as following improvement of the present invention.
