Description

A kind of plug-in type security door

The utility model relates to a kind of security door.

The security door of existing rotary unlatching all is to insert the doorframe pick-proof to stretch out several bolts on the door leaf, the anti-sled of promptly several points, but there is not the weak problem of pick-proof in insertion portion.

The purpose of this utility model will address the above problem exactly, and doorframe can be inserted in the whole piece limit that discloses a kind of door leaf, keeps simultaneously the characteristics that door leaf can revolution switch again.

It comprises doorframe, door leaf, lock, it is characterized in that: the upper and lower of door leaf one side respectively has a fork, one end of last draft link links with door leaf respectively, the other end is respectively with doorframe hinge joint and be positioned at door leaf following rear (establishing the side that door leaf and backplate lean on mutually is the place ahead) in off position, last draft link and connecting rod are affixed, do swing synchronously.Two backplates are fixed in the left and right sides of doorframe respectively and are positioned at the direction of opening the door.Also have, one or more buckle expansion link is arranged on the left side of door leaf or the right side, there are a convex body or concave volume in doorframe or backplate and buckle expansion link corresponding section.

Its effect is: after door was shut, limit, the door leaf left and right sides was all in backplate.It is stronger than several bolts insertion doorframe pick-proof abilities that doorframe is inserted on the whole piece limit of door leaf.The characteristics that door leaf can revolution switch have been kept.

1, the two ends of going up draft link (6) adopt the rotating shaft strand to practice respectively or the hinge strand is practiced and linked, and connecting rod (5) directly serves as rotating shaft and swing link end part welding or screw are fastening up and down, also the middle part of connecting rod and last draft link can be welded or screw fastening.Two backplates (7) be fixed in respectively doorframe (1) about two, be positioned at the front of doorframe (1), the direction of promptly opening the door, their are with welding or together with doorframe (1) bending and molding.The width of backplate (7) is wanted can make the pass behind the door, and the dual-side of door leaf all within it.

When opening the door, door leaf (2) is that fulcrum is swung with hinge joint place of fork (6) and doorframe (1) earlier, B shifts to A by the position, unlatching one side of door leaf (2) (side that fork (6) is relative) is promptly thrown off the backplate (7) on the doorframe (1), this moment, hinge joint place with door leaf (2) and fork (6) was a fulcrum, turned to open.

At closing time, earlier with door leaf (2) rotation reduction, be located at A place, and then door leaf (2) is moved to B by A, the unlatching side of door leaf (2) promptly inserts in the backplate (7) on the doorframe (1) at this moment, and opposite side is still in backplate.Catch on or block or withstand doorframe (1) by the lock (3) on the door leaf (2) at last, make it must not withdraw from backplate (7).

2, the rotating band moving gear tooth bar or the connecting rod of lock (3) or handle (4), control buckle expansion link (8) turnover when stretching out, is withstood doorframe (1), and door leaf (2) is pushed up to B by position A; During indentation, its gib head catches on convex body (9) or the concave volume on doorframe (1) or the backplate (7), and door leaf (2) is pulled to A by position B.

Claims (2)

1, a kind of plug-in type security door, comprise doorframe (1), door leaf (2), lock (3), it is characterized in that: the end that the upper and lower of door leaf (2) one sides respectively has a pendulum root (6) to go up draft link (6) links with door leaf (2) respectively, the other end links with doorframe (1) respectively and is positioned at rear under door leaf (2) closed condition, last draft link (6) is affixed with connecting rod (5), and two are protected piece (7) and are fixed in the left and right sides of doorframe (1) respectively and are positioned at the direction of opening the door.

2, a kind of plug-in type security door according to claim 1 is characterized in that: on door leaf (2) left side or the right side one or more buckle expansion link (8) is arranged, doorframe (1) or backplate (7) have a convex body (9) or concave volume with buckle expansion link (8) corresponding section.
