DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 2 , Figure 3 and Figure 4 as well as Figure 5 The embodiment of the utility model provides an office shredder, comprising: a body 10, a collecting barrel 11 is arranged inside the body 10, a paper pressing assembly 12 is arranged inside the collecting barrel 11, the paper pressing assembly 12 comprises two pressing plates 121 symmetrically hinged on the inner wall of the collecting barrel 11 and two connecting plates 122 symmetrically slidably connected inside the collecting barrel 11, a protrusion at the bottom of the pressing plate 121 is hinged with a rod body 123, both ends of the rod body 123 are rotatably connected to the inner wall of the collecting barrel 11, both ends of the rod body 123 are installed with transmission gears 124, a toothed portion 125 is arranged on the top of the connecting plate 122, and the outer ring of the transmission gear 124 is meshed with the toothed portion 125, a driving assembly 15 is arranged at the inner bottom of the collecting barrel 11, and the output end of the driving assembly 15 drives the two connecting plates 122 to rise and fall, and a partition 13 is installed inside the collecting barrel 11.

[0021] According to the above technical solution, by using the driving assembly 15, its output end drives the two connecting plates 122 to move upward, and the toothed portion 125 on the top of the connecting plate 122 drives the transmission gear 124. Through the synergistic effect of the toothed portion 125, the transmission gear 124 and the rod body 123, the pressure plate 121 is driven to move along the inner wall of the collecting barrel 11 toward the middle thereof, thereby realizing the pressing effect on the shredded paper in the collecting barrel 11. Through such an arrangement, precise transmission of synergistic effect is realized, and the lifting and lowering of the paper pressing assembly 12 is effectively controlled to ensure uniform and strong compaction of the paper, reduce the volume of the fragments in the collecting barrel 11, and improve the compactness of the shredded paper in the collecting barrel 11, so that the collecting barrel 11 can efficiently recycle more shredded paper, reduce the paper jam caused by shredded paper, and ensure the efficiency and smoothness of the office shredder in processing paper.

[0022] Furthermore, the space between the top of the partition 13 and the top of the collection barrel 11 forms a chamber for accommodating shredded paper, thereby preventing shredded paper from entering the drive assembly 15. Shredded paper can easily cause jamming or damage to mechanical parts in the drive assembly 15. The partition 13 provides a layer of protection to ensure the normal operation of the drive assembly 15.

[0023] In one embodiment of the present invention, Figure 3 As shown, the driving assembly 15 includes a motor 151 installed at the bottom of the collecting barrel 11, and the output shaft of the motor 151 is fixedly connected to a bevel gear Ⅰ152, and the outer ring of the bevel gear Ⅰ152 is symmetrically provided with two transmission members 153, and the top of the transmission member 153 is connected to the internal thread of the connecting plate 122. Through such an arrangement, the motor 151 can transmit power to the connecting plate 122 through the bevel gear Ⅰ152 and the transmission member 153, thereby realizing the control of the paper pressing assembly 12.

[0024] In one embodiment of the present invention, Figure 4 As shown, the transmission member 153 includes a bevel gear II 1531 and two bevel gears III 1533. The outer ring of the bevel gear II 1531 is meshedly connected with the outer ring of the bevel gear I 152. The inner ring of the bevel gear II 1531 is fixedly connected with a connecting rod 1532. The two bevel gears III 1533 are meshedly connected at a vertical angle. The outer ring of the connecting rod 1532 is meshedly connected with the outer ring of one bevel gear III 1533. The inner ring of the other bevel gear III 1533 is fixedly connected with a screw 1534. The outer part of the screw 1534 is threadedly connected with the inner part of the connecting plate 122.

[0025] According to the above technical solution, the power of the motor 151 is effectively transmitted to the connecting plate 122 through the coordinated action of the bevel gear II 1531 , the connecting rod 1532 , the bevel gear III 1533 and the screw 1534 , thereby realizing the lifting movement of the paper pressing assembly 12 .

[0026] In one embodiment of the present invention, Figure 3 As shown, two lifting rings 14 are symmetrically fixedly connected to the top of the partition 13. This arrangement facilitates the installation and removal of the partition 13 and the maintenance or cleaning of the drive assembly 15.

[0027] In one embodiment of the present invention, Figure 5 As shown, the connection between the top of the connecting plate 122 and the toothed portion 125 is constructed in an L-shape, and the L-shaped connection provides adaptability so that the top of the connecting plate 122 can effectively adapt to the shape of the bottom of the pressing plate 121.

[0028] In one embodiment of the present invention, Figure 4 As shown, the paper pressing assembly 12 also includes a sponge plate 126 arranged on the inner wall of the collecting barrel 11, and the sponge plate 126 is located between the inner wall of the collecting barrel 11 and the outside of the pressing plate 121. Through such a setting, when the driving assembly 15 drives the pressing plate 121 to move toward the middle of the collecting barrel 11, direct contact with the pressing plate 121 is blocked, reducing the wear of the inner wall of the collecting barrel 11, thereby protecting the collecting barrel 11.

[0029] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
