File cabinet drawer capable of preventing hands from being pinched and sliding off

Abstract

The invention relates to the technical field of office supplies. The invention discloses a file cabinet drawer capable of preventing hands from being pinched and sliding off. The file cabinet drawer comprises an outer bottom plate, and an electromagnetic rod is fixedly connected to the interior of the outer bottom plate; the side face of the outer bottom plate is fixedly connected with an outer side plate; a ventilation opening is formed in the inner end of the outer side plate, permanent magnets are fixedly connected to the two sides of the ventilation opening, a dustproof plate is fixedly connected to the end of the ventilation opening, a supporting plate is fixedly connected to the interior of the ventilation opening, a spline shaft is rotatably connected to the center of the supportingplate, and fan blades are fixedly connected to the end of the spline shaft. When the inner box body is pushed back, internal air drives the fan blades to rotate, the fan blades are connected with themagnetic induction device, the electromagnetic rod is powered on, and the magnetic pole at the end and the upper end of the magnetic block are synonymous magnetic poles, so that the effects that theinner box body can be automatically retracted after being slightly pushed by a person, the person does not need to continuously push with hands, and hands are prevented from being pinched when the person closes the drawer are achieved.

Description

technical field [0001] The invention relates to the technical field of office supplies, in particular to a filing cabinet drawer that prevents hands from being pinched and slips. Background technique [0002] During the use of the file cabinet, due to the inattention of the personnel, the hand is pinched when the drawer is pushed back, and the drawer is not closed tightly. Too much pull-out force will cause the drawer to be pulled out as a whole, causing internal documents to spill. [0003] In order to solve the above problems, the inventor provides a filing cabinet drawer that prevents hands from being pinched and slips. When the inner box is pushed back, the internal air drives the fan blades to rotate. The fan blades are connected to the magnetic induction device, and the electromagnetic rod is energized. , the magnetic pole at the end and the upper end of the magnetic block are different magnetic poles, so that the inner box can be automatically retracted after the per...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a filing cabinet drawer that prevents hands from being pinched and slips. The drawer is blocked to prevent the files inside it from falling, and it can be automatically closed when the drawer is pushed back, without the need for continuous pushing by the personnel, which prevents the personnel from being pinched. When the drawer is pinched, and the drawer is not closed tightly, when the drawer is pulled out, it will be difficult to pull out the drawer because the contents inside are too heavy. If the force is too large, the drawer will be pulled out as a whole, and the internal documents will be spilled. question
