Abstract

The utility model relates to an anti-drilling, impact-resistant and anti-theft safety door, which belongs to the field of the anti-theft safety door. A door leaf is provided with a special lockset of which the point of a locking hole is provided with an anti-drilling sheet, and the installing position of the lockset uses the locking hole as a center and is provided with an anti-drilling steel-yarn net which prevents the lockset being removed by easily drilling one hole edge for a door body. The upper and the lower sides of the lockset are provided symmetrically with a four-point link gear of a guide rod chamfer. A handle on the lockset is rotated, a guide rod drives a sloping block to move in an axial direction, and the position or the reset of two transversal connector pins and two portrait connector pins can be realized simultaneously. When the door is closed, the handle is operated and the lockset is locked, the four connector pins of the link gear and a lock tongue can together form the bidirectional five-point positioning (three points in the transversal direction, and two points in the vertical direction), and the impact-resistant performance of the door is enhanced.

Description

Anti-drilling, charging-resistant and anti-theft safety door

The utility model relates to a kind of anti-theft safety device, especially can increase the anti-theft safety door of anti-drilling, charging-resistant ability.

The industry standards of public safety GA25-92 of People's Republic of China (PRC) anti-theft safety door by technical condition the 5th, 1,3 and the 5th, 3,7 are that the anti-drilling ability of lockset installation position at center and the impact resistance between door leaf and the doorframe have proposed clear and definite performance requirement with the lockset to anti-theft safety door.At present; the anti-theft safety door that generally uses in the esidential building does not have anti-drilling protective device because of the lockset installation position; anti-drilling ability; and only locate mostly between door leaf and the doorframe by the lockset dead bolt; best also only respectively sets up a vertical latch in the doorframe end of both sides up and down at lockset; keyed end is still less, and is still relatively poor to the protective capability and the impact resistance of dead bolt, loses the anti-theft security effect so subject to violence damage.

The purpose of this utility model provides a kind of anti-theft safety door, and it can not only increase the anti-drilling ability of lockset installation position, and can increase the impact resistance of door, thereby improves the anti-theft security performance.

The purpose of this utility model is achieved in that in the lockset installation position anti-drilling steel yarn net is set, when this position was attacked by drilling, anti-drilling net in time came off and twines drill bit, stops it normally to rotate until twisting off, avoid boring easily Men Tiyi hole and the lockset of dismantling improves anti-drilling ability; Bilateral symmetry is provided with 4 link gears in guide rod inclined-plane about lockset; close behind the door; handle link gear; make lockset up and down two horizontal latches and two vertical latches of arranging of bilateral symmetry locate simultaneously, lock lockset then, dead bolt location and link gear must not be handled; at this moment; just constitute two-way 5 lock-out states (horizontal 3 points, perpendicular 2 points) between door leaf and the doorframe, reached the purpose of protection dead bolt, raising impact resistance.

Because adopt such scheme, the anti-drilling, charging-resistant of the anti-theft safety door ability of hitting strengthens greatly, and easy to operate.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the broken section constructional drawing of anti-theft safety door embodiment.

Fig. 2 is the fundamental diagram of guide rod inclined-plane link gear.Because link gear is with respect to symmetric arrangement about the lockset, so only express the duty of the first half among the figure.

In Fig. 1, door leaf (8) is gone up the special lockset (6) that the lockhole place has anti-drilling sheet is installed, and anti-drilling steel yarn net (5) being set in the installation position that with the lockhole is the center, anti-drilling net (5) is slightly fixing all around, makes it in time come off and to twine rotary drilling-head until twisting off.A horizontal latch (3) and a vertical latch (1) respectively are set both sides up and down at lockset (6),, can make four latches locate simultaneously or reset by the bar handle guide rod inclined-plane link gear on the lockset (6).

In Fig. 2, be welded with the skewback (2) of a pair of reversed arrangement on the guide rod (4), and pass the slotted hole of leaving on the horizontal hollow cylinder latch (3), and laterally latch (3) is bearing in the cylindrical hole of door leaf (8) frame, and the upper end of guide rod (4) is welded with a vertical latch (1).At closing time, rotate the handgrip on the lockset (6), guide rod (4) drives skewback (2) and moves, locate simultaneously latch (3) and (1), realize two-way four point locations between door leaf (8) and the doorframe (7), lock lockset (6), dead bolt location and pinning handgrip must not rotate, two-way five point locations of common formation this moment.When opening the door, open lockset (6), dead bolt resets, backward rotation handgrip then, and guide rod (4) drives skewback (2) and moves, and latch (3) and (1) can reset simultaneously.

Claims (3)

1, a kind of anti-drilling, charging-resistant anti-theft safety door, it comprises door leaf, doorframe, lockset, anti-drilling steel yarn net and guide rod inclined-plane link gear, it is characterized in that: anti-drilling steel yarn net is arranged on the lockset installation position; Guide rod inclined-plane link gear symmetry is installed in the both sides up and down of door leaf lockset.

2, anti-theft safety door according to claim 1 is characterized in that: around installation lockhole place has the special lockset of anti-drilling sheet, be that the center is provided with anti-drilling steel yarn net with the lockhole, and slight fixing around the anti-drilling net.

3, anti-theft safety door according to claim 1 is characterized in that: guide rod inclined-plane link gear is made up of guide rod, skewback, horizontal latch and vertical latch; One end of guide rod is connected with the lockset handgrip, and the guide rod other end is welded with vertical cylinder latch; The guide rod middle part is welded with the skewback of a pair of reversed arrangement, and passes the oval through hole that horizontal hollow cylinder latch middle part is left, and laterally the latch two supports is in the cylindrical hole of door leaf frame; Horizontal latch of each symmetric arrangement of both sides and a vertical latch about lockset.
