Abstract

The utility model discloses a paper shredder, which is characterized in that the frame 1 is provided with rotating shaft 11 and 12 side by side, the rotating shaft 11 and 12 are hinged with a motor 18, the gear 16 and 17 form a transmission structure, a plurality of fixed bases 13 are provided through the rotating shaft 11 and 12, between every two fixed bases 13 a cushion block 14 and a cutting blade 15 are provided, the cutting blade 15 are placed in an edge overlapping way, the fixed bases 13 is provided with gaps 131 on its outer edge so that the cusp part 192 of two < typed baffling plates 19 can be inserted within the gaps 131, two clamping rods 21 are fixed on the inner edge of the cusp part 192 of the baffling plate so that the cutting blade is prevent the external expanding deformation under the outer force.

Description

A kind of shredder

The utility model relates to the shredder that a kind of office uses.

The structure of existing shredder, usually lie in a framework and establish, in rotating shaft, wear several holders and cushion block again, between each cushion block, insert and put blade with rotating shaft side by side, and make two rotating shaft blades overlap-like, after inserting paper between two blades, the rotation of blade can be cut into paper the fringe shape, because blade only is set in the rotating shaft, when it rotates, very easily, after long-term use, cause metaboly, influence cutting effect because of the paper bearing force expands outwardly.

The purpose of this utility model provides a kind of each blade that prevents and expands outwardly the shredder of distortion.

The technical solution of the utility model:

This novel shredder includes a skeleton frame, be provided with rotating shaft side by side in this skeleton frame, for wearing several holders, be provided with ring-type cushion block and blade between each holder, two rotating shafts are articulated in the transmission mechanism of being made up of gear and motor respectively, the outer rim of holder is to be little pointed outer teat, be provided with the breach of setting for baffle plate in outer teat, wherein, baffle plate is＜shape, and baffle plate is embedded at its pointed section in the breach of holder, sets a clamping bar in the pointed section inner edge, this baffle plate formation holds holder, can prevent that blade from expanding outwardly distortion.Again, the two ends of this baffle plate are respectively equipped with several latches of outside projection, on the fixing hole that is fixed in skeleton frame.

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1 is a perspective exploded view of the present utility model.

Fig. 2 is a schematic top plan view of the present utility model.

Fig. 3 is a generalized section of the present utility model.

Fig. 4 is a three-dimensional combination schematic diagram of the present utility model.

1 is skeleton frame, and 11 are rotating shaft, and 12 are rotating shaft, and 13 is holder, and 131 is breach, and 14 is cushion block, and 15 is blade, and 16 is gear, and 17 is gear, and 18 is motor, and 19 is baffle plate, and 191 is latch, and 192 is pointed section, and 20 is fixing hole, and 21 is clamping bar, and 22 is screw.

Consult Fig. 1, shown in Figure 2, the utility model mainly contains a skeleton frame 1, skeleton frame 1 is provided with two rotating shafts 11 side by side, 12, in this

rotating shaft

11,12 are arranged in respectively in several holders 13, and be provided with two ring-type cushion blocks 14 in 13 of each holders, between two cushion blocks 14, insert and put an annular blade 15, two rotating

shafts

11,12 are articulated in respectively by

gear

16,17 and the transmission mechanism formed of motor 18, when motor 18 rotates, to drive rotating shaft 11 simultaneously, 12 are relative direction rotates, because two rotating

shafts

11,12 set each blade 15 are overlap-like in its edge, therefore, when paper is inserted by 15 on the blade that overlaps, be able to paper is cut into most tiny fringe shapes, to reach the shredded paper effect.

The outer rim of aforementioned each holder 13, system is little pointed evagination, be provided with a breach 131 in this outer rim, for one be＜baffle plate 19 of shape sets, these baffle plate 19 two ends outwards stretch out several latches 191 respectively, behind the fixing hole 20 that is fixed in skeleton frame 1, the pointed section 192 of baffle plate 19 just can be embedded in the breach 131 of each holder 13, and be locked on the screw 22 of skeleton frame 1 with a clamping bar 21, make its pointed section that is resisted against baffle plate 19 192 inner edges, to constitute each holder 13 is held effect, when each blade 15 when rotating, prevent that it from expanding outwardly distortion.

Again as shown in Figure 3, Figure 4, after the utility model assembling, should＜pointed section 192 of shape baffle plate 19 is embedded at respectively in the breach 131 of each holder 13, and because pointed section 192 inner edges of baffle plate 19 are equipped with a clamping bar 21, two baffle plates 19 are inwardly held with certain strength, so, each holder 13 can keep the location because of the bearing force of baffle plate 19, when each blade 15 when rotating the cutting paper, be able to because of baffle plate 19 inside bearing forces, prevent that it from expanding outwardly, produce to avoid metaboly.

In sum,,, make the blade of being located at holder side by side when rotating cutting, prevent that it from expanding outwardly distortion, can increase the service life of shredder with the effect that holds of formation to holder because the outer rim of the holder of this novel shredder is provided with＜the shape baffle plate.
