Description
Technical field
The utility model relates to the security door technical field, relates in particular to the pick-proof technical construction of security door.
Background technology
According to country's " anti-theft safety door general technical specifications " regulation, qualified security door utilized portable power tools such as ordinary hand tools such as chisel, screwdriver, crowbar and Electric portable drill to pry open in 15 minutes or opens one 615 square millimeters opening at door leaf, or opened one 38 square millimeters opening in the semicircle of 150 square millimeters of keyed ends.Reach this requirement, particularly will reach and prevent from destroying dead bolt by crowbar, and even unload the purpose of whole door-plate, security door not only has higher requirement of strength on the material, and the structure of lockset has also been proposed more special requirement.Except main lock, also require the secondary lock of combination of interlock usually.
The design feature of serious analysis flat opening security door is not difficult to find that the security door locking is main by the dead bolt of lockset on the door-plate and tight chimeric realization of the lockhole on the doorframe.Instruments such as crowbar firmly destroy the chimeric of dead bolt and lockhole or destroy dead bolt as long as embed crack between a door and its frame, have also just realized the purpose of forcing open the door and entering the room.
Summary of the invention
The utility model provides a kind of pick-proof structure of flat opening security door just in order to address the aforementioned drawbacks, and the utlity model has simple in structure, pick-proof, firm advantage.
The purpose of this utility model is achieved by the following technical solution:
A kind of anti-picking device of flat opening security door comprises the doorframe, the shop front that embed the body of wall both sides, and the utility model doorframe is U-shaped groove, offers shop front rotational positioning pin-and-hole and the shop front locking dead bolt hole of symmetry at cell wall;
The shop front comprises door leaf and push-and-pull slide mechanism, connects by folding hinge between door leaf and the push-and-pull slide mechanism; The push-and-pull slide mechanism comprises flexible pin and the flexible stretching bar of selling of control of aiming at shop front rotational positioning hole.
The shop front is provided with door handle, and door handle inserts by lockset control dead bolt or the shop front locking dead bolt hole that contracts.
Push-and-pull slide mechanism described in the utility model comprises slide bar, is enclosed within the flexible pin at slide bar two ends, and the stretching bar is connected with flexible pin by flexure strip respectively, and the stretching bar also is connected with slide bar by spring; The front end of stretching bar is protruding.
The utility model is set with stopping means at slide bar.Stopping means is spacing ring, limited block, banking pin.
The material of the utility model doorframe is metal.
The utility model door leaf is provided with jacking block, and jacking block cooperates with the stretching bar.
The beneficial effects of the utility model are that the shop front that is made of door leaf and push-and-pull slipper slips into the on-deformable high duty metal doorframe that embeds body of wall, the dead bolt on the shop front and the tight chimeric locking that realizes of locking dead bolt hole that is hidden in the doorframe.This door is when being in the lock state, because the high duty metal doorframe is not yielding, so instruments such as crowbar put forth effort to allow the shop front of locking realize slide displacement nowhere, this has also just reached the effect that prevents from forcing open the door and enter the room.
Below in conjunction with the drawings and specific embodiments the utility model is done further explanation.

The specific embodiment
See Fig. 1～shown in Figure 4, a kind of anti-picking device of flat opening security door comprises the doorframe 1, the shop front 2 that embed the body of wall both sides, and the utility model doorframe 1 be U-shaped groove, and the shop front rotational positioning pin-and-hole 5 and the shop front that offer symmetry at cell wall lock dead bolt hole 6;
The shop front 2 comprises door leaf 3 and push-and-pull slide mechanism 4, connects by folding hinge 7 between door leaf 3 and the push-and-pull slide mechanism 4; Push-and-pull slide mechanism 4 comprises flexible pin 8 and flexible 8 the stretching bar 11 of selling of control of aiming at shop front rotational positioning hole 5.
The shop front 2 is provided with door handle 16, and door handle 16 inserts or the shop front locking dead bolt hole 6 that contracts by lockset 9 control dead bolts 10.
Push-and-pull slide mechanism 4 described in the utility model comprises slide bar 12, is enclosed within the flexible pin 8 at slide bar 12 two ends, and stretching bar 11 is connected with flexible pin 8 by flexure strip 13 respectively, and stretching bar 11 also is connected with slide bar 12 by spring 14; The front end of stretching bar 11 is protruding.Shop front rotational positioning pin-and-hole 5 and flexible pin 8 at intervals, and the length of flexible pin 8 wants long enough, make flexible pin 8 all not to be reduced to draw slide mechanism 4 is inner and stretch out after can snap in the shop front rotational positioning pin-and-hole 5.
