Abstract

The utility model provides a safety device of a paper shredder paper insert scoop, comprising a machine cover, and three microswitches fixed and installed on the machine cover, and the utility model is characterized in that a slide safety controlling device is arranged between the machine cover and three microswitches. The safety controlling structure operates when the fingers of a child or excess papers are inserted into the paper insert scoop, to make the microswitches connected with the safety controlling structure operate, and to shut off the power supply to make the machine stop working, so the child fingers cutting danger is avoided to happen. The operation of the utility model is safe, and the condition that a plurality of paper gets into the machine core and the cutting tool is locked are prevented, and the service life of the machine is increased. When the child fingers remove or the paper is reduced, the circuit is connected under the effect of the safety controlling structure and the machine works normally.

Description

A kind of safety device of paper inlet of paper shredder

Technical field:

The utility model relates to shredder, especially the safety device of paper inlet of paper shredder.

Background technology:

The shredder main body is a mainframe box, is provided with the paper inlet of a paper cutting on the top of mainframe box, when paper is inserted into this inlet; Cause operating circuit to be connected by the blocking-up infrared ray, thereby start; There is potential safety hazard in this structure; One, when child played shredder, finger blocks infrared ray and make machine startup caused the danger of cutting finger; When child inserted paper paper inlet of paper shredder and carries out shredded paper, hand may be clipped in the middle of the paper and be drawn into paper inlet, finds the danger of cutting finger; Two, as user during, though when the shredder machine is blocked mostly, reverse function is arranged accidentally with the paper of too excessive input shredder, but the paper of utmost point excess enters the stuck phenomenon of machine may take place, it is malfunctioning to fall back, and armrest is moving to move back paper by force, influences the service life of machine.

Summary of the invention

The utility model provides a kind of improved shredder, and a kind of ingenious, handling ease, safety device easy for installation of designing is provided at traditional paper inlet of paper shredder place, has thoroughly solved the deficiency of above-mentioned shredder.

The utility model is achieved in that

A kind of safety device of paper inlet of paper shredder includes: cover, be fixed on three microswitches on the cover, it is characterized in that being provided with the slidingtype security control mechanism between cover and three microswitches.

This slidingtype security control mechanism comprises: security control bar, be located at two spacing holes on the cover, two guiding pads, two fixtures, two back-moving springs.

The security control bar is provided with three boss, it is characterized in that the switch contact of corresponding three microswitches of three boss, and the switch contact under nature touches mutually with boss.

Advantage of the present utility model is: in case child's finger stretches into paper inlet, the security control bar moves along cover upper limit hole under external force, the microswitch action that is attached thereto, host power supply is cut off, machine quits work, the situation of having avoided child's finger to be cut takes place, and shredder uses safer;

Equally, when excessive paper inserts paper inlet, machine quits work, and paper did not enter cutter and just cut off the power supply this moment, and the phenomenon of avoiding the machine intimate cutter to be stuck has been protected cutter, has improved the service life of machine.

Child's finger is removed, or reduces the shredded paper number, and external force reduces, and under the spring force effect, the security control bar resets, and switch contact resets, and circuit is connected, the machine operate as normal.

The utility model is simple in structure, and is easy to process, quick for installation.

Description of drawings:

Fig. 1 is traditional shredder cover structure schematic diagram.

Fig. 2 is a structural representation of the present utility model.

Fig. 3 is a partial sectional view of the present utility model.

Fig. 4 is a local amplification view of the present utility model.

Among the figure: 1, cover, 11, paper inlet, 12, spacing hole, 2, the security control bar, 21, boss, 3, microswitch, 31, switch contact, 4, spring, 5, the guiding pad, 6, fixture.

The specific embodiment:

See also Fig. 3, a kind of safety device of paper inlet of paper shredder comprises: cover 1, and being fixed between 3, three microswitches 3 of three microswitches on the cover 1 and the cover 1 has the slidingtype security control mechanism; The slidingtype security control mechanism comprises: security control bar 2, be located at two spacing holes 12 on the cover 1, two guiding pads 5, two 6, two back-moving springs 4 of fixture; Security control bar 2 is provided with 21, three boss of three boss, 21 corresponding three switch contacts 31, and microswitch 3 is fixed on the position on the cover 1, guarantees that the switch contact 31 under nature just touches mutually with boss 21.

See also Fig. 4, when child finger or too much paper insert paper inlet of paper shredder 11, under external force, security control bar 2 is moved to the left along spacing hole 12, guiding pad 5 is fixed on the security control bar by fixture 6, boss 21 is pressed into the switch contact 31 of microswitch 3, microswitch 3 actions, and the host computer control circuit is cut off.

See also Fig. 4, when child finger leaves or reduces the paper number that inserts shredder, external force reduces, and under spring 4 effects, security control bar 2 moves to right along spacing hole 12, and switch contact resets, and host circuit is connected, the machine operate as normal.
