Description

A safety device that can close the paper passage of the shredder

technical field

The utility model relates to a paper shredder, in particular to a safety device which can close the outlet below the paper feeding channel to avoid injury when fingers are inserted into the paper opening.

Background technique

In order to prevent legal files, financial receipts, invoices, credit card account numbers, research reports on official business, or financial information of family members such as credit card monthly statements, phone bills and other documents from being leaked into the wrong hands, usually the Confidential files or data are destroyed using shredders to prevent data leakage. So the paper shredder has become an indispensable equipment for business and home life.

The US Consumer Product Safety Commission (CPSC) issued document No. 5127 in May 2004 for the Paper Shredder Safety Alert. The document mainly reminds families who own paper shredders to pay special attention to the safety of family members when operating paper shredders. Be cautious about cases of finger injuries, and most of the injured are children aged 14 months to 2 years old, especially toddlers who have just started learning to walk. Because children at this stage like to imitate the actions of adults very much, playing with the shredder when adults are not paying attention and causing injury. Even when an adult is watching, there is no guarantee that the injury will not happen, because the pulling force generated by the shredder on the paper during the shredding process, assuming that the fingers holding the paper cannot be released in time (let the paper go), then The pulling force may pull fingers into the shredder opening and cause injury.

Therefore, CPSC warns consumers to pay attention to the following when using paper shredders:

1. Never let young children operate the shredder alone. Even with the supervision of an adult, you must pay attention to the danger that the pulling force of the shredder may pull the fingers of the child into the paper inlet of the shredder;

2. Put the shredder in a place where children are not easy to reach;

3. Unplug the power plug when the shredder is not in use;

4. Avoid placing hands or fingers on the shredder;

5. Do not operate the shredder while wearing loose clothes, so as not to be rolled into the paper inlet of the shredder;

6. Keep a safe distance between ties or necklaces and the paper inlet of the shredder.

The width of the paper inlet of a general paper shredder may allow young children to reach in and be cut or even crushed by knives. Therefore, it is necessary to install a safety protection device at the position of the paper inlet to avoid regrets caused by fingers extending into the paper inlet.

Utility model content

In view of this, the main purpose of the present utility model is to provide a safety device, which can close the paper inlet passage when the finger is inserted into the paper inlet of the shredder, so as to avoid cutting or even crushing caused by the finger.

In order to achieve the above purpose, the utility model provides a safety device that can close the paper inlet channel of the shredder, including: a shredder shell with a paper inlet; a touch pressure plate, pivotally connected to the shredder The vicinity of the paper inlet of the machine casing moves with the pivot joint as the axis; a closing component is driven by the pressing plate to move between the open position and the closed position of the paper inlet channel.

The utility model is a safety device that can close the paper inlet channel of the shredder. The movable pivot near the paper inlet of the shredder contacts the pressing plate. The pivot position rotates clockwise, and then drives a set of transmission mechanisms and gates to close the opening below the paper feeding channel, so that fingers cannot go deeper to avoid injury; once the pressure on the pressing plate disappears, the reset component will The touch plate returns to the normal position and drives the closure assembly to leave the closed position and return to the normal open position.

Detailed ways

The features of the utility model can be clearly understood by referring to the drawings and the detailed description of the embodiments.

Please refer to FIG. 1 the plane structure diagram of the utility model in the normal position and FIG. 2 the plane structure diagram of the utility model after the pressure plate is pressed.

The entrance position 11 (that is, the paper inlet) above the paper inlet passage of the shredder housing 1 shown in FIG. 1 is movable and pivotally connected with the pressure plate member 2, and the pivot position 21 of the pressure plate member 2 is provided with a return assembly 3 , the return assembly 3 is a torsion spring in this embodiment, one end of the torsion spring is resisted against the inner edge of the pressure plate, and the other end is fixed on a sector-shaped driving gear 41 of a group of transmission mechanisms, and the sector-shaped driving gear 41 is fixed on Touch the pivot position 21 of the plate 2, and further mesh with the first driven gear 42, and the first driven gear 42 meshes with the second driven gear 43, and the second driven gear 43 meshes with a rack type gate 5 engaged;

Please refer to Fig. 2, when the pressure plate 2 is subjected to the pressure (as shown by the arrow F) generated by the fingers extending into the paper opening, the pressure plate 2 will be pivotally connected with the shredder housing 1 according to it. Position 21 is the axis that rotates clockwise, and drives the sector-shaped driving gear 41, the first driven gear 42 and the second driven gear 43 in the transmission mechanism to rotate synchronously as shown by the arrow, and then drives the second driven gear 43 meshed rack gate 5 moves to the outlet position 12 below the paper inlet channel to close it; when the above-mentioned pressure plate 2 is pressed and rotates clockwise, the torsion spring 3 is torsionally compressed to store its recovery kinetic energy.

When the pressure F of the finger on the aforementioned touch plate 2 disappears due to the finger leaving, the torsion spring 3 will release the original accumulated kinetic energy to make the touch plate 2 rotate counterclockwise and return to the normal position, and simultaneously drive the fan-shaped drive in the transmission mechanism simultaneously. The gear 41, the first driven gear 42 and the second driven gear 43 rotate in reverse, and then drive the rack-type gate 5 meshing with the second driven gear 43 to leave the exit position 12 below the paper inlet path to make it open .

The technical content and technical features of the present utility model have been disclosed above, but those who are familiar with the technology may still make various replacements and modifications based on the disclosure of the utility model without departing from the spirit of the utility model. Therefore, the protection scope of the utility model should not be limited to the disclosed embodiments, but should include various replacements and modifications that do not deviate from the utility model, and are covered by the scope of the patent application.
