Abstract

An antiprize door comprises a door frame (3) and a door leaf (1) in hinge connection with the door frame, which is characterized in that: a concave antiprize groove (4) is vertically arranged on the outboard door face of the door leaf (1); the outer side of the door frame (3) is provided with an antiprize vertical wall (5) which extends toward the direction of the door leaf then bends toward the direction of the antiprize groove and can stretch into the antiprize groove. The utility model has the antiprize function capable of preventing poking pieces from being inserted in, and can improve the closure airtightness of the door leaf and the door frame.

Description

Anti-forcing open the door

The utility model belongs to a kind of anti-forcing open the door.

The door of forming by doorframe and with the hinged door leaf of doorframe is usually as shown in Figure 1: doorframe 3 is with a step, closed door leaf 1 is stuck on the doorframe step, when door leaf being pinned with doorframe, be easy to turn 90 degree bend cuttings from the outside with a toughness plectrum and go into crack between a door and its frame dead bolt is pushed aside with dead bolt 2.

The utility model aims to provide and a kind ofly is difficult for making the toughness plectrum to insert the anti-of crack between a door and its frame forcing open the door.

The technical scheme that realizes above-mentioned purpose is (referring to implementing illustration): the utility model comprises doorframe (3), with the hinged door leaf of doorframe (1), it is characterized in that: vertically be provided with recessed safety groove (4) on the shop front of door leaf (1) outside, doorframe (3) outside is provided with to the door leaf direction extends again to the crooked pick-proof wall (5) that also can stretch into safety groove of safety groove direction.

When the utility model door leaf (1) and doorframe (3) are closed, pick-proof wall (5) on the doorframe can stretch in the safety groove (4) on the door leaf naturally, want that like this toughness plectrum is inserted crack between a door and its frame and push dead bolt aside, will make plectrum turn four 90 degree bends, this is difficult to accomplish, so the utlity model has the tamper-resistant function that can prevent that plectrum from inserting, but also can improve the sealing of door leaf and doorframe closure.

Embodiment 1 (Fig. 3):

The utility model is best suited for the aluminium extruded sections structure door, and this example is the embodiment that is used for the aluminium extruded sections door.

This routine door leaf 1 is made up of Door leaf frame 7 and the door-plate 6 that is clipped between the Door leaf frame, near with Door leaf frame 7 outer side surfaces of doorframe 3 closed sides on, be provided with a safety groove 4 longitudinally, on doorframe 3 outer side surfaces, be provided with along the extended surface 8 that extends with the door leaf parallel direction, extended surface is provided with the pick-proof wall 5 that can vertically stretch into safety groove, on the position between pick-proof wall and the doorframe on the extended surface 8, be provided with and be lower than pick-proof wall 4, the wool top clamping wall 9 that is higher than extended surface 8, the function one of wool top clamping wall is to play position-limiting action to the pick-proof wall, prevent that its end from pushing up safety groove bottom, damage safety groove or pick-proof wall, the 2nd, but the clamping seal weatherstrip is with the gap sealing between door leaf and the doorframe.

Embodiment 2 (Fig. 4,5)

This example is the rolling-gate (having proposed patent application simultaneously) of a band wicket, the wicket of handle switch promptly has been installed on rolling-gate, this example is to be provided with a dismountable center pillar 10 to make the wicket doorframe between two side columns, in order to improve tamper-resistant safety, wicket that this is routine and center pillar 10 are closed the position and have been adopted pick-proof structure of the present utility model.

Wicket door leaf 1 is made up of Door leaf frame 7 and the door-plate 6 that is clipped between the Door leaf frame, near with Door leaf frame 7 outer side surfaces of center pillar 10 closed sides on, be provided with a safety groove 4 longitudinally, on center pillar 10 outer side surfaces, be provided with along the extended surface 8 that extends with the door leaf parallel direction, extended surface is provided with the pick-proof wall 5 that can vertically stretch into safety groove, is provided with the wool top clamping wall 9 that is lower than the pick-proof wall, is higher than extended surface on the position between pick-proof wall and the doorframe on the extended surface 8.

This rolling-gate has improved its safety and sealing performance after adopting the utility model pick-proof structure.
