Description
Technical field
The utility model relates to a kind of daily necessities, relates in particular to a kind of antitheft mailbox.
Background technology
In the prior art, though the mail in the mailbox has the door lock keyed, because mailbox window slit is bigger, mail is often stolen by some people, and particularly some important mail in case stolen, will cause hardly imaginable consequence.
Summary of the invention
Have defective for overcoming prior art, the utility model provides the triangulo column that both makes the mailbox window increase rotation, reduces the slit of window, and the size of mailbox profile need not be changed, and receives mail normally, guarantees the antitheft mailbox that mail no longer runs off.
For achieving the above object, the technical solution of the utility model is: a kind of antitheft mailbox, comprise mailbox, be characterized in, be equipped with the plane triangulo column parallel in the window of described mailbox with window, three length of sides of this triangulo column end face equate, and be the center with the crosspoint of the center line of three length of sides, a left side is set, the circular hole that the right side communicates, pass the circular hole of triangulo column by central shaft, the two ends of central shaft are welded in a left side in the mailbox, right both sides, the length of side of described triangulo column length and triangulo column end face and the length of mailbox window and wide suitable, the internal diameter of middle part circular hole and the external diameter of central shaft are suitable, and the length of described central shaft equals the length in the mailbox.
The beneficial effects of the utility model are to have both to make the mailbox window increase the triangulo column that rotates, and reduce the slit of window, and the size of mailbox profile need not be changed, and receive mail normally, guarantee the antitheft mailbox that mail no longer runs off.And the middle triangulo column that be equipped with circular hole parallel with window plane is set in the window of mailbox, and triangulo column is welded in and arranged on left and right sides in the mailbox by central shaft, when mail is filled in window, triangulo column rotates under the effect of central shaft, after mail enters mailbox, the another side of triangulo column has blocked window again, triangulo column makes the window slit of mailbox reduced, the window of again not worrying mailbox makes mail stolen too greatly, the utility model is simple in structure, safe, easily manufactured, with low cost.
