Abstract

The utility model belongs to an anti-picking door and in particular relates to an anti-picking door with internal and external locking mechanism. The utility model is mainly composed of a door leaf frame, a lock chamber and locking mechanisms. The locking mechanisms comprise gear boxes. A driving gear, an upper gear rack and a lower gear rack are equipped in the box. One ends of the upper gear rack and the lower gear rack, which protrude from the box, are respectively connected with an upper vertical connecting rod, a lower vertical connecting rod, an upper horizontal connecting rod, a lower horizontal connecting rod, an upper slide block and a lower slide block in order. Part of the upper gear rack, which protrudes from the box, is equipped with a handle. The handle protrudes from a T-shaped hole on the internal door plate. When the handle is lifted into a horizontal hole on the upper end of the T-shaped, the handle can be clamped. The anti-picking door provided by the utility model is simple in structure, convenient in use, safe and reliable.

Description

Anti-prizing door with internal and external locking mechanism

The utility model belongs to a kind of anti-forcing open the door, and particularly has the anti-of inside and outside retaining mechanism and forces open the door in a kind of.

Anti-forcing open the door on the present market, the kind style is a lot, but how by interior, the empty belly door of outer two-layered steel plates, be provided with a transmission mechanism at intraperitoneal, on the door body, respectively there are two locking points at following two ends, find that in actual applications the anti-performance of forcing open the door of this class still is not ideal enough, this is owing to existing pick-proof door lock mechanism, when indoor pinning, still can be in outdoor unlatching, therefore, the dead of night, though owner with door from indoor pinning, the offender can seize the opportunity outdoor door is opened (being mostly technical unlocking), burglary, even hurt sb.'s feelings the existing anti-middle fatal shortcoming that exists of forcing open the door that Here it is.

The purpose of this utility model just is to overcome the shortcoming that exists in the prior art, through development test repeatedly, proposes a kind ofly to have the anti-of inside and outside retaining mechanism and force open the door, and promptly the outdoor use key can't be opened when indoor locking.

Anti-technical scheme of forcing open the door and structure with inside and outside retaining mechanism of the present utility model is: it is mainly by Door leaf frame, the lock chamber and the retaining mechanism that are positioned at the door leaf middle part are formed, the retaining mechanism that it is characterized in that locking in the chamber comprises a gear-box, be located at the driving gear in the gear-box and stretch out gear-box outer and by in the driving gear control, following tooth bar, last, following tooth bar outer end portion is not connected with, following vertical connecting rod, last, following vertical connecting rod end is respectively with last, lower transverse connecting rod is connected, last, sealed slide block respectively is equipped with in the lower transverse connecting rod outside, described slide block can insert respectively doorframe on, in the lower transverse beam, and handle is housed on the part outside upper rack stretches out gear-box and offers keyhole at the driving gear core.On the door leaf inner plate surface of described handle position, offer T shape hole, handle can be moved up and down in this T shape hole, also can in the cross-drilled hole of upper end, T shape hole, rotate and block.The sealed slide block that is contained on the described upper and lower tranverse connecting rod is three.

Using this anti-unlatching of forcing open the door or the state when sealed is such, at outdoor insertion key, key is stirred the driving gear rotation, by the upper and lower tooth bar ascending, descending of gear driven, by upper and lower vertical connecting rod, upper and lower tranverse connecting rod makes the respective aperture on insertion of locking slide block or the disengaging doorframe.At the indoor handle that exposes outside T shape hole that uses, just sealed to rising, promptly open toward descending.When falling asleep night, handle can be risen in the cross-drilled hole of T shape hole upper end and rotate 90 °, handle is stuck in the cross-drilled hole, like this, even turn the key in the lock, because handle has been positioned in the cross-drilled hole in T shape hole outdoor, key can't be stirred driving gear, make upper and lower tooth bar activity, promptly can't so just realize in indoor multiple spot locking in outdoor unlatching.

Anti-forcing open the door compared with prior art of the present utility model has the following advantages:

1, this anti-forcing open the door has after indoor locking, can't prevent that the robber from swarming at night from the special function of outdoor unlatching, and is safe and reliable;

2, originally anti-locking slide block of forcing open the door is upper and lower respectively three, and multi-point fastening is safer firm like this;

3, this anti-retaining mechanism of forcing open the door also can be united use with other horizontal retaining mechanism;

4, this anti-locking mechanism structure of forcing open the door is simple, easy to manufacture, easy to use, sturdy and durable.

In order to further specify the anti-structure of forcing open the door with inside and outside retaining mechanism of the present utility model, specifically describe with reference to the accompanying drawings and in conjunction with the embodiments, its accompanying drawing has:

Fig. 1 is this anti-outer side elevation partial sectional view of forcing open the door;

Fig. 2 is this perpendicular sectional view in anti-lock chamber of forcing open the door;

Fig. 3 is this anti-inside stand view of forcing open the door.

Embodiment:

As shown in Fig. 1-3, be provided with the lock chamber at door leaf 1 middle part, center position is equipped with a gear-box 10 in the lock chamber, in gear-box 10, be provided with driving gear 7, driving gear 7 both sides are equipped with the upper and lower tooth bar 6 that is engaged with respectively, but with key handsetting gear 7 and make the upper and lower tooth bar 6 upper and lower liftings of both sides.External part at upper and lower tooth bar 6 is connected with upper and lower vertical connecting rod respectively, and in upper and lower tranverse connecting rod 4 outsides each three of locking slide blocks is housed respectively, and they can insert respectively in the upper and lower crossbeam of doorframe.In the driving gear outer side center door lock head 9 is housed, and has keyhole therebetween; Extension at upper rack 6 is equipped with handle 8, and expose outside the T shape hole 12 in being opened in internal hilar plate, when handle 8 rises in the cross-drilled hole of 12 upper ends, T shape hole, rotate 90 ° handle is stuck in the cross-drilled hole, retaining mechanism can't be opened with key at outer side of door.
