Description

The shredder of tool safety cut-off switch and safe cut-off switch thereof

Technical field

The utility model refers to a kind of shredder and safe cut-off switch thereof that has safe cut-off switch and have the tool safety cut-off switch of dustbin function concurrently especially relevant for a kind of shredder.

Background technology

General shredder is except can destroying classified papers, more can shred paper in order to recovery, itself all has a power switch each shredder, and to control the power supply of shredder, the operator uses for convenient, power switch mostly is to be opening, when desiring shredded paper, directly paper is sent into paper feed port, yet finger is stretched in the paper feed port when child that happens occasionally plays, even there are tail of cat or the tongue of dog to be involved in the shredder facts that damages.Moreover the paper shredding barrel of traditional shredder below can only hold general shredded paper, owing to shift out the mode of paper shredding barrel, the shredder of top must be moved, and considerably therefore trouble does not have the function of dustbin.

The utility model people in view of this, the industry experience for many years is engaged in accumulation, is study intensively and test improvement repeatedly, nowadays creates a kind of shredder of novel tool safety cut-off switch finally, can forgo and commonly use the product shortcoming, to promote effect.

Summary of the invention

The utility model purpose is to provide a kind of shredder and safe cut-off switch thereof of tool safety cut-off switch; be provided with the touch panel on plane in the paper feed port periphery of general shredder; when operator or animal limb stretch into paper feed port because of carelessness and touch contact plate, but the shredder hard stop.In addition, the user is as long as with the light pedal of pin, just can shift out the interior bucket of paper shredding barrel, conveniently to abandon rubbish.

Technical solutions of the utility model: a kind of shredder of tool safety cut-off switch, it is characterized in that, comprising:

One body, the touch panel that top paper feed port periphery has conduction;

One housing, front side and top have the empty portion of thread, and the bottom leading edge has a pedal, and the pedal bolt has a plate, and connecting plate rests on the axostylus axostyle, and it holds bolt that one top board is arranged in addition, and this top board extends in the breach of frame;

Bucket in one, the top has opening, and inserts in the housing.

Wherein, housing leading edge both sides have cross bar, and interior bucket bottom edge both sides have the embedding hole, and the cross bar of housing is embedded in the embedding hole of interior bucket.

A kind of used safe cut-off switch of shredder as above-mentioned tool safety cut-off switch, it is characterized in that: comprise the touch panel that is positioned at shredder paper feed port periphery, touch panel and one is used for control relay the shredder circuit breaker is linked with the circuit board of cutting off the electricity supply, this circuit board includes a discharge cell that is connected and composed by a relay and a diode, and is used to control the amplifying circuit of this relay; Wherein, this relay is connected with output with the input of motor respectively, and the relay top also has one in order to be connected to the gauge tap of DC positive source input with control relay.

The utility model beneficial effect: by said structure, the utility model is provided with a pedal in the paper shredding barrel front side, outside user's foot pedal just can be tilted to interior bucket, to abandon rubbish; Moreover the paper feed port periphery of body is provided with touch panel or electric conductor, and when human body, animal, metal or water are desired to enter paper feed port and when touching touch panel, but the shredder hard stop has been guaranteed the safety of using.

Understand in order to allow the auditor that the utility model is had further, Zi Zuo is as follows with graphic detailed description the utility model.

The specific embodiment

Be placed with shredder body 20 as Fig. 1 paper shredding barrel of the present utility model 10 tops, paper feed port 21 peripheries of body 20 tops post the touch panel (touch board) 22 of conduction;

Cooperate Fig. 2, paper shredding barrel 10 is made up of

housing

11 and 12 in interior bucket, and the front side of housing 11 and top thread are empty, and the top, bottom has two vertical bar chutes 11, inboard tool one locating hole 112 of chute 111; Interior bucket 12 is the staving of a top end opening, its the place ahead tool one header board 121, the slide rail 122 (as Fig. 3) of bottom tool two vertical bars, inner edge tool one pulley 123 of slide rail 122, in bucket 12 slip in the chute 11 of housing 11 with slide rail 122, and mat pulley 123 slides in chute 11, and pulley 123 also can embed location in the locating hole 112 of chute 11 inboards; When interior bucket 12 slipped in the housing 11 fully, the header board 121 of interior bucket 12 and housing 11 formed the paper shredding barrel of a monolateral opening.Header board 121 tops of interior bucket 12 have a form 1211, can detect the amount of shredded paper in the paper shredding barrel; The top, both sides of housing 11 is the shrinkage pool 113 of tool one arc respectively, is convenient to both hands paper shredding barrel 10 is lifted.

One of principal character of the present utility model is: as the bottom edge of Fig. 4 housing 11 pedal 13 is installed, these pedal 13 bolt a plate 14, this connecting plate 14 rests on the axostylus axostyle 15, form a seesaw structure, connecting plate 14 is held then bolt one top board 16 in addition, and this vertical top board 16 stretches out the breach 114 of housing 11; When interior bucket 12 was placed on the housing 11, the bottom coping 16 of interior bucket 12 was downward, and the plate 14 that is connected simultaneously is horizontal with pedal 13; Cooperate shown in Figure 5ly, during user's foot pedal 13, connecting plate 14 is that the center drives upwards bucket 12 in the top of top board 16 with

axostylus axostyle

15, and 12 in interior bucket is outward-dipping conveniently abandoning rubbish, when pin leaves pedal 13, then in bucket 12 can return to original state again.Leading edge both sides as Fig. 2 housing 11 2 chutes 11 are respectively equipped with a cross bar 17, in the embedding hole 124 of bucket 12 leading edge both sides, break away from housing 11 with bucket in preventing 12 in this cross bar 17 can embed.
