In the present application, an axially retractable printer driving head 3 is a conventional art, as shown in fig. 12, a printer driving gear set is disposed on an outer side of a printer side wall 320, a driving gear is driven by an electric driving gear to engage with a driven gear 311, the driven gear 311 is provided with a central hole 311a and penetrates through the printer side wall 320, the driving head 3 penetrates through the central hole 311a, ends of a driving shaft 31 and a driving arm 32 are located on an inner side of the printer side wall 320, an elliptical hole 313 is formed at an outer end of the driving head 3, and a pin shaft 314 is radially installed in the elliptical hole 313 and fixed in the driven gear 311; the rear part of the driving head 3 is provided with a shoulder, a compression spring 315 is sleeved outside the shoulder at the rear part of the driving head 3, and the other end of the spring 315 is pressed against a side cover plate 321 of the printer, so that the driving head 3 keeps a forward extending trend in an initial state. How to realize the axial extension and contraction of the printer driving head 3 is not a limitation to the protection scope of the present application.
When the existing printer generally adopts the printer driving head 3 which can not stretch, the carbon powder box transmission structure adopts the transmission part 1 which can axially stretch.
The head of the printer driving head is in a spherical crown shape and comprises a driving shaft 31 and a driving arm 32, the front end part of the transmission part 1 is provided with a pair of engaging claws 11 and a claw base 12 which are used for engaging with the driving arm 32 on the printer driving head 3, and the transmission shaft 2 is radially arranged at the tail end part of the transmission part 1, is embedded in the toner cartridge gear 4 and is used for driving the toner cartridge gear 4 to rotate; the diameter of the driving shaft 31 is d1, the diameter of the driving arm 32 is d2, the total length of the driving arm 32 is a, and the vertical height from the top end point of the driving shaft 31 to the lower edge of the driving arm 32 is h; the claw base 12 is in a circular truncated cone shape, an inverted circular truncated cone-shaped concave part is arranged at the center of the upper side of the circular truncated cone, the outer side surface of the claw base 12 and the inner side surface of the concave part respectively form an outer slide guiding inclined surface 121 and an inner slide guiding inclined surface 122, the upward extending vertical height of the engagement claw 11 from the top point of the outer slide guiding inclined surface 121 is H2, and the opening width of the top part of each engagement claw 11 is L; the following dimensional constraints are satisfied between the transmission member 1 and the printer driving head 3: h2 < (H + d 2/2); l > (a + d 1)/2.
The working principle of the product of the invention is as follows:
during the engagement, the head of the driving shaft 31 rises to the top along the outer sliding guiding slope 121, H2 < (H + d2/2) is restricted, and the top end of the engaging claw 11 is under the axial center of the driving arm 32 arranged in the radial direction. When the driving member 1 slides downwards along the inner sliding guiding slope 122, if the engaging claw 11 contacts the driving arm 32, the top end of the engaging claw 11 contacts the lower surface of the driving arm 32, and in the mutual pressing process of the engaging claw 11 and the driving arm 32, a component force along the axial direction inevitably pushes the driving arm 32 and the engaging claw 11 to separate, and the driving member 1 is deflected by the radial component force, so that the phenomenon that the driving member 1 and the driving head 3 of the printer are jammed due to contact interference is avoided.
At the end of the engagement stroke, the head of the driving shaft 31 slides down along the inner guiding and sliding slope 122 into the concave portion, and the two ends of the driving arm 32 are engaged and driven with the locking positions on the two engaging claws 11. At this time, the clearance between the drive shaft 31 and the two engaging claws 11 is (L-d 1)/2.
During the disengagement process, the head of the driving shaft 31 is lifted to the top along the inner guiding and sliding slope 122 and then lowered along the outer guiding and sliding slope 121 until the disengagement is completed by an external force perpendicular to the axial direction of the driving member 1.
In the disengaging process, if the driving shaft 31 contacts the inner side of one of the engaging claws 11 and the two ends of the driving arm 32 cannot be simultaneously disengaged from the two engaging claws 11, the driving arm 32 is caused to contact and interfere with the two engaging claws 11 and to be locked.
In order to avoid the interference and jamming phenomena of the driving arm 32 and the two engaging claws 11 in the disengaging process, the product of the invention fully utilizes the clearance between the driving shaft 31 and the two engaging claws 11 through size design, and the driving shaft 31 is disengaged from the other engaging claw 11 in the process that the clearance between the driving shaft 31 and one of the engaging claws 11 is gradually reduced, so that the jamming phenomena caused by the contact of the two ends of the driving arm 32 and the two engaging claws 11 and the contact of the driving shaft 31 and the inner side of one of the engaging claws 11 are avoided. When the drive shaft 31 ascends along the inner slide guiding surface 122, the gap between the drive shaft 31 and one of the engagement claws 11 is gradually reduced, and at this time, the end of the drive arm 32 contacting the other engagement claw 11 is inevitably disengaged. The contact width of any end of the driving arm 32 with one engaging claw 11 is (a-L)/2, the gap between the driving shaft 31 and the two engaging claws 11 in the engaged state is (L-d1)/2, and by restricting the dimension (a-L)/2 < (L-d1)/2, the contact end of the driving arm 32 with the other engaging claw 11 is ensured to complete disengagement in the process of gradually reducing the gap to zero, namely: l > (a + d 1)/2.
The vertical height of the outer sliding guide inclined plane 121 of the transmission piece 1 is H1, and the vertical height of the inner sliding guide inclined plane 122 is H3; the vertical height H1 of the outer lead-in ramp 121 is greater than one-half of the radius d2 of the driving arm 32 of the printer driver head, i.e.: h1> d2/2, so that the head of the drive shaft 31 rises to the top along the outer slide guiding slope 121 by at least d 2/2. When the driving arm 32 on the driving shaft 31 is located below and close to the top ends of the two engaging claws 11 in the initial state, the driving shaft 31 and the driving arm 32 are lifted upwards by at least d2/2 height by the outer guide sliding inclined surface 121, which is convenient for assembling and using in the printer.
The vertical height H3 of the inner lead ramp 122 is greater than one-half the radius of the actuator arm 32 of the printer actuator head, i.e.: h3 & gt d2/2, the driving shaft 31 and the driving arm 32 slide downwards at least d2/2 height together through the inner guide sliding slope 122, under the meshing state, H3+ H2 & gt H + d2 enables the axis of the driving arm 32 on the driving shaft 31 to be located below the top ends of the two meshing claws 11 and to be meshed with the clamping positions of the meshing claws 11, and the driving arm 32 rotates and is meshed with the clamping positions on the meshing claws 11 to form an interference clamping state, so that the printer is convenient to assemble and use.
H3 ═ H1 is preferred.
The radial inner and outer sides of the rotating axial cross section of the engaging claw 11 of the transmission member are sharp corners, the outer sides form outer guide sliding surfaces 111, and the inner sides form inner guide sliding surfaces 112.
Inside the engaging claw of the driving member, the top end of the circular truncated cone of the claw base is provided with a step-shaped sliding guide surface 15 formed by a horizontal plane and an inclined plane. The inclined surface is an arc surface protruding from the inner slide guiding inclined surface.
A non-cylindrical guide section 13 for adjusting the rotation stop position of the engaging claw 11 is further provided on the lower side of the claw base.

The vertical height value H2 of the engagement claw 11 is smaller than the sum of the vertical distance H from the top end point of the drive shaft 31 of the printer drive head to the lower edge of the drive arm 32 and the radius d2/2 of the rotating arm 32, namely: h2 < (H + d 2/2).
The width L of the top opening of the two engaging claws is larger than half of the sum of the total length a of the drive arm 32 and the diameter d1 of the drive shaft 31, that is: l > (a + d 1)/2.
And (3) an engagement process:
when the toner cartridge is loaded into the printer, as shown in fig. 4a-1, when the driving member 1 horizontally pushes and horizontally abuts against the driving head 3, the spherical crown part of the driving head of the printer contacts with the outer sliding guiding inclined surface 121 of the driving member, under the action of the external installation force, the driving head 3 slides back to the driving member 1 and slides from the lower position of the outer sliding guiding inclined surface 121 to the upper position, and because H2 < (H + d2/2), that is, when the driving head 3 is located at the highest position of the outer sliding guiding inclined surface 121, as shown in fig. 4a-2, the top end surface of the engaging claw 11 is located below the driving arm 32, so that mutual abutting interference is not formed; when the spherical crown of the driving head passes over the highest position of the sliding guide slope, the driving head 3 slides back along the inner sliding guide slope 122 and enters the concave part of the claw base 12, as shown in fig. 4a-3, the engaging claw 11 and the driving arm 32 are at the same horizontal position to be engaged, and the driving head enters an engaging state after rotating. Even if the tip end surface of the engagement claw 11 interferes with the lower edge of the driving arm 32 when the driver head 3 slides back into the concave portion of the claw base 12, the driving arm 32 and the engagement claw 11 are dislocated by itself and slide back into the concave portion of the claw base 12 after the driver head 3 rotates.
When the toner cartridge is loaded into the printer, as shown in fig. 4b-1, when the transmission member 1 is horizontally pushed longitudinally to be in translation butt joint with the driving head 3; the outer corner edge of the engaging claw 11 is contacted with the driving head 3 of the driving head of the printer in a butting way, and the butting contact area is very small, so that the driving member 1 is deviated to the left or the right, the outer guide sliding surface 111 of the engaging claw 11 is collided with the driving shaft 31 after the deviation and further slides to generate relative rotation, and when the driving member 1 rotates to be not interfered by the butting contact of the engaging claw 11, the flat push butting situation as shown in fig. 4a is achieved, namely, as shown in fig. 4b-3 and fig. 4 b-4.
Disengaging the engagement process:
when the toner cartridge is taken out, as shown in fig. 4c-1, when the driving member 1 and the driving head 3 are engaged in the horizontal direction, under the action of external pulling force, the driving head 3 and the driving member 1 slide in the opposite direction and slide from the lower position of the inner guiding inclined plane 122 to the upper position, and because H3 is greater than d2/2 and H2 is less than (H + d2/2), that is, when the driving head 3 is located at the highest position of the guiding inclined plane 122, as shown in fig. 4c-2, the top end surface of the engaging claw 11 is located below the axial center of the driving arm 32, the engaging claw 11 and the driving arm 32 are disengaged without interference, and when the driving head spherical cap passes over the highest position of the guiding inclined plane, the driving head 3 slides back along the outer guiding inclined plane 121, as shown in fig. 4c-3, the driving member 1 and the printer head 3 are completely disengaged, and the toner cartridge can be taken out of the printer smoothly.
When the toner cartridge is taken out, as shown in fig. 4d-1, when the driving member 1 is engaged with the driving head 3 in the longitudinal direction, under the action of an external pulling force, the driving head 3 and the driving member 1 slide in the opposite direction, and slide from the lower position to the upper position of the inner sliding guide slope 122, as shown in fig. 4d-2, because H3> d2/2, H2 < (H + d2/2), and L > (a + d1)/2, that is, when the driving head 3 is located at the highest position of the sliding guide slope 122, the top end surface of the engaging pawl 11 is located below the driving arm 32, the engaging pawl 11 is disengaged from the driving arm 32 in the axial direction, and the engaging pawl 11 is separated from the driving arm 32 in the radial direction, and do not interfere with each other; meanwhile, the inner corner edge of the engaging claw 11 is in interference contact with the top spherical crown portion of the driving shaft 31, and due to the small interference area, the driving member 1 will be deviated to the left or to the right, and the spherical crown portion of the driving shaft 31 will further slide and rotate relative to the inner guiding sliding surface 112 of the engaging claw 11, until the engaging claw 11 and the driving head 3 do not form interference, and then continue to disengage as shown in fig. 4c, that is, as shown in fig. 4d-3 and fig. 4 d-4.
Preferably, in order to compensate for the insufficient deflection angle generated by the engagement claw 11 with the sharp-angled structure, a non-cylindrical guide section 13 for adjusting the rotation-stop direction of the engagement claw 11 is further arranged below the claw base 12, and the guide section 13 on the toner cartridge and the pair of engagement claws 11 above the same always tend to stop at the direction easy for the printer driving head 3 to transversely and horizontally push in through the combined action of the guide section 13 and the torsion spring of the toner cartridge or the guide plate of the printer.
As shown in fig. 6a, the side cover 60 on the toner cartridge is designed with a torsion spring 61, the torsion spring 61 is sleeved on the column head of the side cover 60 on the toner cartridge, the other end of the torsion spring 61 abuts against the guide section 13, and when the shaft of the transmission member 1 is in a non-meshed state, the transmission member 1 rotates around the center under the torsion action of the torsion spring 61, so as to ensure that the guide section 13 on the toner cartridge and the pair of meshing claws 11 thereon always tend to stop at a position where the printer driving head 3 is easy to horizontally push and slide in.
As shown in fig. 6b, the printer 30 is provided with a guide plate 36, when the toner cartridge is installed and removed, the guide section 13 radially touches the guide plate 36 in the printer, the guide plate 36 slides over the pointed portion of the guide section 13, and the transmission member 1 rotates around the center, so as to ensure that the guide section 13 on the toner cartridge and the pair of engaging claws 11 thereon always tend to rest in an orientation that is easy for the printer driving head 3 to slide in by horizontal pushing.
Embodiment two of the transmission member:
for a printer driving head with a flat head, the structure of a transmission part is as follows:
a transmission part of a toner cartridge comprises a transmission part 1 and a printer driving head connected with the transmission part.
As shown in fig. 2B, the head of the printer driver head is flat, and specifically the driving shaft 31 is configured as a small, full-circle cylinder surrounding a non-full-circle large cylinder, and the driving shaft 31 is flat when viewed radially and has a non-circular section 33, shown as a B-direction section. Correspondingly, the engaging claws 11 of the transmission member 1 have the following structure:
as shown in fig. 2a, inside the engaging claw of the transmission member, a stepped slide guide surface 15 formed by a horizontal surface and an inclined surface is provided at the tip end of the circular truncated cone of the claw base. The inclined plane is an arc surface protruding from the inner sliding guiding inclined plane, and in the structure, when the driving shaft 31 climbs to the top horizontal plane through the inclined plane, and the driving shaft 31 has a supporting point capable of axially staying when the driving shaft 31 is at the top horizontal plane, in the process, the gap between the driving shaft 31 and one of the engaging claws 11 is gradually reduced, and one end of the driving arm 32 is separated from the other engaging claw 11, and then a non-cylindrical guide section 13 for adjusting the rotating and stopping position of the engaging claw 11 is arranged below the claw base 12 in a matching manner, and the torsion spring 61 is designed on the side cover 60 on the carbon powder box, so that in the supporting process when the driving shaft 31 stays at the top horizontal plane, the transmission member 1 deflects under the matching of the guide section 13 and the torsion spring 61 and tends to stay at the position where the printer driving head 3 is easy to.
The remaining structures, dimensional constraints, features, etc. are the same as the embodiment of the transmission and will not be repeated.
And (3) an engagement process:
in the non-engaged state of the driving member 1, the engaging pawl 11 is always stopped in an orientation in which it is easy for the printer head 3 to be laterally pushed and slid in, by being subjected to the elastic force of the torsion spring 61.
When the toner cartridge is loaded into the printer, as shown in fig. 5a-1, the transmission member 1 always transversely faces the driving head 3, the top of the printer driving head contacts against the outer sliding guide slope 121 of the transmission member, under the action of the installation external force, the driving head 3 and the transmission member 1 slide backwards, the spring 5 is compressed, meanwhile, the transmission member 1 retracts axially, the transmission member 1 slides from the lower position of the outer sliding guide slope 121 to the upper position, and because H1> d2/2, H2 < (H + d2/2), and L > (a + d1)/2, that is, when the driving head 3 is located at the highest position of the outer sliding guide slope 121, as shown in fig. 5a-2, the top end surface of the engaging claw 11 is located below the driving arm 32, therefore, mutual abutting interference is not formed; when the top end of the driving head passes the highest position of the sliding guiding slope 121, the spring 5 is released, and at the same time, the driving member 1 moves axially outwards, the driving head 3 slides back along the inner sliding guiding slope 122 into the concave portion of the claw base 12, as shown in fig. 5a-3, the engaging claw 11 and the driving arm 32 are at the same horizontal position to be engaged, and the driving head enters an engaged state after rotating.
Disengaging the engagement process:
when the toner cartridge is removed, as shown in figure 5b-1, the driver 1 is in lateral engagement with the drive head 3. The engagement claw 11 is stopped at an orientation in which it is easy for the printer driving head 3 to be laterally pushed flat and slid. Under the action of external pulling force, the driving head 3 and the driving member 1 slide backwards, the spring 5 is compressed, the driving member 1 retracts axially, the driving member 1 slides from the lower position to the upper position of the inner sliding guide inclined plane 122, and because H3> d2/2 and H2 < (H + d2/2), namely when the driving head 3 is located at the highest position of the sliding guide inclined plane 122, as shown in fig. 5b-2, the top end surface of the engaging claw 11 is located below the driving arm 32, and the engaging claw 11 is disengaged from the driving arm 32 without interference. When the top end of the driving head passes the highest position of the sliding guide slope, the spring 5 is released, and simultaneously the driving member 1 moves axially outwards, the driving head 3 slides back along the sliding guide slope 121, as shown in fig. 5b-3, the driving member 1 and the printer head 3 are completely disengaged, and the toner cartridge can be smoothly taken out from the printer.
When the toner cartridge is taken out, as shown in fig. 5c-1, when the driving member 1 is engaged with the driving head 3 in the longitudinal direction, under the action of an external pulling force, the driving head 3 and the driving member 1 slide in the opposite direction, the spring 5 is compressed, and the driving member 1 retracts axially, so that the driving member 1 slides from the lower position of the inner slide guiding slope 122 to the upper position, that is, the top end of the driving shaft 31 falls on the step-shaped slide guiding surface 15. As shown in fig. 5c-2, since H3 is greater than d2/2, H2 < (H + d2/2), and L > (a + d1)/2, the top end surface of the engaging pawl 11 is located below the driving arm 32, the engaging pawl 11 is disengaged from the driving arm 32 in the axial direction, and the engaging pawl 11 is radially separated from the driving arm 32 without interfering with each other; meanwhile, as the transmission member 1 retracts, the transmission shaft 2 passes over the lower top end of the rotation stop block 43 of the gear, so that the transmission member 1 is in a rotation-unimpeded state in which the front rotation is not impeded by the rotation stop block 43 and the rear rotation is not impeded by the driving arm 32. Under the action of the elastic force of the torsion spring 61, the transmission member 1 rotates, so that the engagement claw 11 is always stopped at an orientation in which the printer driving head 3 is easily horizontally pushed and slid; or under the elastic force of the spring 5, the transmission shaft 2 continues to rotate forward along the guiding and sliding inclined plane 432, so that the transmission member 1 rotates to the longitudinal position. The disengagement continues as shown in fig. 5c-3,5 c-4.
