Abstract

The utility model relates to an anti-picking door, which belongs to the manufacturing technique of anti-picking house doors for outerdoor door of house buildings, or exchequers and storehouses of office buildings, etc. An anti-drilling main lock is arranged in the middle of a door leaf; the main body of the main lock is a locking device in a shape like the Chinese character'jing'; an outer shell of the device is square flat box; a driving gear is arranged in the center of the flat box; an upper, a lower, a right and a left racks engaged with the gear can form the shape like the Chinese character'jing' and can extend outside the box for connecting with locking rods with four directions in the door leaf; the top of each locking rod forks and forms two bolts; the two bolts are engaged with grooves arranged on a corresponding door frame. Compared with the congener art, the utility model has multiple functions of multiple locking points, drilling resistance, shifting resistance, picking resistance, etc. Especially, the locking device in the shape like the Chinese character'jing' has the advantage of flexible transmission and does not have the phenomena of technical disengagement of teeth disengagement, teeth slide, skewing, etc.

Description

Anti-forcing open the door

The utility model relates to a kind of anti-forcing open the door, and belongs to residential building and divides exterior door or interior accounting office of unit office building and storehouse etc. to require the Room door controller technology for making of pick-proof.

At present known anti-forcing open the door, though increased the locking point in vertical or horizontal direction, while locking, the function that multiple spot is firm have been realized in various degree, but as the locking device of anti-drilling main lock still exist rotate dumb, easily take off technology such as tooth, slip teeth, skew phenomenon partially by mistake, door leaf answers intensity influenced by frame construction in advance simultaneously, has also reduced tamper-resistant function.

The purpose of this utility model be provide a kind of in order to overcome above-mentioned weak point of the prior art and have that vertical, horizontal direction locking, multiple spot firmly, anti-drilling, anti-are dialled, pick-proof and main latching operation flexibly, anti-forcing open the door easily.

The purpose of this utility model is achieved in that door leaf is a steel plate die mould assembly welding, rivet into the box body structure of reinforcing bar framework hollow, one side is equipped with conventional anti-drilling secondary lock, the door leaf middle part is equipped with anti-drilling main tapered end, with this main tapered end supporting and with the main lock main body of its formation one be the intersecting parallels locking device, it is box-like partially that the shell of this locking device is square, at the center of flat box one driving gear is housed, on this gears engaged, down, a left side, the tooth bar of right four direction constitutes well word shape and extends to outside the flat box, each tooth bar respectively be arranged in the door leaf on, down, a left side, the locking bar of right four direction connects, each locking bar top fork is told two dead bolts, matches with the groove that is provided with on the corresponding doorframe.When inserting lockhole, key does the locking rotation, thereby driving the upper and lower, left and right tooth bar does vertical and stretching horizontal direction simultaneously, the fork on the locking bar top that is connected with tooth bar divides dead bolt to kiss in the doorframe groove, finish the locking program, when key revolution is done to open when rotating, more than each parts do opposite transmission, the tooth bar withdrawal, locking bar resets, and dead bolt is finished opening program by withdrawing from the doorframe groove.

The utility model compared with prior art, many weak points in the similar technology have been overcome, have vertical, horizontal direction simultaneously locking, multiple spot fasteningly, anti-drilling, anti-dial, tamper-resistant function, especially the intersecting parallels locking device of the utility model design, have more ensuring smooth transmission, safety factor value height, do not have and take off technology such as tooth, slip teeth, skew phenomenon partially by mistake, the door leaf inner skeleton is a well word frame-type structure, strengthened door-plate and answered intensity in advance, made it to accept to dial power from the more powerful impact in front or the bar sled of shouldering of side end face.

The explanation of accompanying drawing drawing:

Fig. 1 sees schematic diagram outdoors for the utility model pick-proof.

Fig. 2 is the anti-built-in steel skeleton construction schematic diagram of forcing open the door of the utility model.

Fig. 3 is intersecting parallels locking device of the present utility model and locking bar, dead bolt structural representation.

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

Door leaf of the present utility model (8) is installed on the doorframe (25) by bearing hinge (5), this door leaf (8) adopts steel plate die mould assembly welding, rivet into the box body structure of hollow, door leaf (8) inner skeleton is a well word reinforcing bar framework (6), (7) type structure, strengthen door-plate and answered intensity in advance, inner big extensive angle sight glass (1) and the doorbell (2) installed of door-plate, sidepiece is installed and is paid lock (3), anti-drilling main tapered end (4) is installed at the middle part, with this main tapered end (4) supporting and with the main lock main body of its formation one be intersecting parallels locking device (14), the shell of this locking device (14) is the flat box of square (10) shape, a driving gear (17) is equipped with at the center of this flat box (10), in this gear (17) engagement, down, a left side, the tooth bar (9) of right four direction, (18), (13), (21) constitute well word shape and extending to outside the flat box (10), each tooth bar (9), (18), (13), (21) respectively be arranged in the door leaf (8) on, bottom left, the locking bar (22) of right four direction, (16), (22), (20) connect, each locking bar top fork is told two dead bolts (23), (15), (11), (19), going up the groove (24) that is provided with corresponding doorframe (25) matches.Driving gear (9) is by key turns, its drives is drawing locking bar (22), (16), (12), (20) with four tooth bars (9), (18), (13), (21) of its engagement and is doing the motion of stretching, contract, realize that each locking pike pole divides dead bolt (23), (15), (11), (19) are with locking or open door leaf (8), main tapered end (4) and intersecting parallels locking device (14) are given and have been closed four tooth bars (9), (18), (13), the location of (21), logical heart condition, have realized that promptly ensuring smooth transmission eliminated tooth bar again and taken off tooth, slip teeth, the misoperation of skew isogonic.

Claims

1, a kind of anti-forcing open the door, comprise by the steel plate die mould, rivet into the door leaf of the box body structure of reinforcing bar framework hollow, be installed in the anti-drilling main tapered end at door leaf middle part, it is characterized in that with this main tapered end supporting and with the main lock main body of its formation one be the intersecting parallels locking device, it is flat box-like that the shell of this locking device is square, at the center of flat box one driving gear is housed, on this gears engaged, down, a left side, the tooth bar of right four direction constitutes well word shape and extends to outside the flat box, each tooth bar respectively be arranged in the door leaf on, down, a left side, the locking bar of right four direction connects, each locking bar top fork is told two dead bolts, be provided with on the corresponding doorframe groove match.
