Description

Anti-theft door

The utility model relates to a kind of security door, especially a kind of security door that is used for a public latching point lock door.

At present the kind of security door is extremely various, and built-in lock is arranged more, and the shift fork that drives of handle or key, or gear makes the slide bar latch make stretching motion, makes to open and locking.And because door body and lockset constantly perfect, crime is unblanked, and it is more and more difficult to work the body of forcing open the door.But still keep away unavoidable offender and use various portable instruments to carry out the destructiveness attack, as drilling, cutting etc. lockset is come off.

The purpose of this utility model is to provide the security door of a public latching point lock door of a kind of usefulness, makes self-locking and the tripper simplification and the safety, reliable of door.

The purpose of this utility model is achieved in that a kind of security door, comprise a body (2), built-in lock (4), hand bright (3), shift fork (8), inserted link (10), (14), balladeur train (15), fixed pulley group (12), movable pulley (19) and soft rope (18), an end that it is characterized in that soft rope (18) passes the race cover of movable pulley (19) in first pulley race of fixed pulley group (12), the other end cover of wheel rope (18) has the latch (13) of spring at movable pulley (19) cover around the race one side screw thread of soft rope (18) one one end that spins in second pulley groove adjacent with first pulley.When the built-in lock of door or handle or shift fork were destroyed or come off, soft rope all can get loose, and latch is established within it and ejected under the spring action and prop up the long pawl of stop, made a body still keep lock-out state and can not open, and realized insuring antitheft purpose.

Because the utility model has adopted such scheme, Bolt with latching action has played the effect of a public latching point, has satisfied the requirement of the multiple strick precaution of security door, thereby makes that the suitable application area of this security door is more wide, and the use of security door is safety, reliable also.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1, appearance assumption diagram of the present utility model;

Fig. 2, door body inner pin tool structure drawing of device;

The fundamental diagram of Fig. 3, public latching point;

Fig. 4, A-A section, the Bolt with latching action structure chart;

Fig. 5, stop claw structure chart;

Fig. 6, latch side cutaway view.

Among the figure: 1-doorframe, 2-door body, 3-handle, 4-built-in lock, 5-peephole, 6-built-in hinge, 7-connecting rod, 8-shift fork, 9-stop claw, 10-inserted link, 11-driving lever, 12-fixed pulley, 13-latch, 14-inserted link, 15-balladeur train, 16-spring, 17-slide, the soft rope of 18-, 19-movable pulley.

By Fig. 1,2,3,4,5,6, the utility model comprises that a body 2, built-in lock 4, hand are bright 3, shift fork 8, inserted link 10,14, balladeur train 15, fixed pulley group 12, movable pulley 19 and soft rope 18, it is characterized in that an end of soft rope 18 passes the race cover of movable pulley 19 in first pulley race of fixed pulley group 12, the other end cover of wheel rope 18 has the latch 13 of spring at movable pulley 19 cover around the race one side screw thread of soft rope 18 one one end that spins in second pulley groove adjacent with first pulley.A side of door body 2 is connected with doorframe 1 by built-in hinge 6 in the following embodiments, and handle 3 is coaxial fixed with shift fork 8.Built-in lock 4 is housed on the door body reaches by slide 17, spring 16, soft rope 18 self-locking mechanism that movable pulley 19 fixed pulleys 12 grades constitute.Control crank 3 can pass through shift fork 8 as can be seen, makes inserted link 10,14, balladeur train 15, makes stretching motion, realize the locking and the unlatching of door body, and built-in lock 4 can be shift fork, and inserted link etc. are stuck or loosen.So, built-in lock 4, handle 3 shift forks 8 are keypoint parts that this body lockset has, what promptly need to take precautions against will put the position.Here by movable pulley 19(Fig. 3) the soft rope 18 of fixed pulley 12 usefulness is tied the latch 13 of built-in lock 4 and shift fork 8 with self-locking device, and soft rope 18 is a tensioned state, makes latch 13 be in the state of drawing the bow but not discharge the arrow.In case built-in lock 4, or handle 3 and shift fork 8 destroyed or come off, and all can cause getting loose of soft rope, and then Bolt with latching action 13 ejects the overhanging stop claw 9 that props up under the effect of spring 16, and inserted link 10 can not be fallen, and makes a body still keep lock-out state, can not open.

Here only two critical positions have been controlled with a latching point.Utilize public latching point of effect of assembly pulley can control a plurality of critical positions equally, mechanism can control 4 critical positions as shown in Figure 4.Here make self-locking and tripper simplify greatly, and only need rotating lever 11 to get final product complete release.

Claims (1)

1, a kind of security door, comprise a body (2), built-in lock (4), hand bright (3), shift fork (8), inserted link (10), (14), balladeur train (15), fixed pulley group (12), movable pulley (19) and soft rope (18), it is characterized in that an end of soft rope (18) passes the race cover of movable pulley (19) in first pulley race of fixed pulley group (12), the other end cover of wheel rope (18) has the latch (13) of spring at movable pulley (19) cover around the race one side screw thread of soft rope (18) one one end that spins in second pulley groove adjacent with first pulley.
