CN201246059Y - Safe box - Google Patents

Abstract

The utility model relates to a safe box which comprises a movable door body, a square lock plunger and a door frame with a lock hole, wherein a movable lock catch is arranged in the middle of the square lock plunger, a catch edge is respectively formed at the two ends of the movable lock catch, one end of the movable lock catch is connected into the central hole of the square lock plunger through an axle, the other end thereof is a movable end, the catch edge at the movable end is a bevel edge, the width of the lock hole is larger than the width of the square lock plunger, and a bulge for limiting the fore-and-aft movement of the lock plunger is formed inside the lock hole. The safe box has the advantages that by adding the movable lock catch, the movable lock catch can clip the bulge when the safe box or a safety-deposit box is unlocked, thereby achieving double theft prevention and further increasing the safety of the safe box or the safety-deposit box.

Description

Strongbox

Technical field

The utility model relates to a kind of strongbox or safe deposit box.

Background technology

The lock of existing strongbox or safe deposit box is made up of locking bolt and lockhole, locking bolt is unblanked or is locked by travel mechanism's control turnover lockhole by key, because cooperating between lockhole and the locking bolt is fairly simple, only be simple square locking bolt and the cooperation between the square lockhole, therefore prized easily, not too safe.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art and a kind of strongbox is provided, and makes its pick-proof, safer more.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

Strongbox, the doorframe that comprises dodge gate body, square locking bolt and hole with lock, it is characterized in that: in the middle of the described square locking bolt movable snap close is set, movable snap close two ends respectively are with a button limit, the one end is connected by axle in the interstitial hole of square locking bolt, and the other end is a movable end, movable end with the button limit be hypotenuse, described lockhole width is greater than the width of square locking bolt, and the projection that moves forward and backward at the inboard restricted locking bolt of lockhole mouth.

Above-mentioned snap close can be two or more, is set up in parallel or upper and lower settings, so further safety.

Compared with prior art, advantage of the present utility model is:

By the movable snap close that increases, make movable latching in when strongbox or safe deposit box are locked can fasten projection, reach dual pick-proof, thereby further increase the safety of strongbox or safe deposit box.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, strongbox or safe deposit box comprise the fixed gate limit 2 in dodge gate 6, square locking bolt 3 and hole with lock 21.

Whole lock (not shown) is arranged on the dodge gate 6, and square locking bolt 3 is fixed on the fixed strip 8 of lock travel mechanism by bolt 9, and moves along with locking or unblanking.

Movable snap close 5 one ends are fixed on by axle 4 on the space of square locking bolt 3 centres, and movable snap close 5 two ends respectively are with a button limit 52,53, and button limit 53 is a hypotenuse.

Corresponding square locking bolt 3 places are provided with lockhole 21 on the fixed gate limit 2, and described lockhole 21 is greater than the width of square locking bolt 3, and in lockhole mouth inboard projection 22 are arranged, and work to limit square locking bolt 3 and move forward and backward.

As shown in Figure 3, when key drive lock travel mechanism locks, travel mechanism drives square locking bolt 3 and enters lockhole 21, when running into limit 7 on one side 52 of movable snap close 5, on one side 52 stressed and the another side 53 of movable snap close 5 is rotated and is buckled in the lockhole 21, and by projection 22 restrictions, square like this locking bolt 3 and movable snap close 5 cooperate together, can limit whole lock and move forward and backward, can limit its move left and right again, so safety be improved more.

When key drive lock travel mechanism unblanks, when travel mechanism's drive locking bolt 3 leaves lockhole 21, because the button limit 53 of movable snap close 5 is a hypotenuse, so enters under the drive of its power in the interstitial hole of locking bolt 3 and leave lockhole 21 and finally unblank with locking bolt 3 left.

Claims (2)

1, strongbox, the doorframe that comprises dodge gate body, square locking bolt and hole with lock, it is characterized in that: in the middle of the described square locking bolt movable snap close is set, movable snap close two ends respectively are with a button limit, the one end is connected by axle in the interstitial hole of square locking bolt, and the other end is a movable end, movable end with the button limit be hypotenuse, described lockhole width is greater than the width of square locking bolt, and the projection that moves forward and backward at the inboard restricted locking bolt of lockhole mouth.

2, strongbox as claimed in claim 1 is characterized in that: described snap close can be two or more, is set up in parallel or upper and lower settings.
