The utility model is characterized in that a connecting rod (2) or (22) is connected with the lock core (7) via a transmission mechanism, at least one lock bolt (5) is arranged on the connecting rod, and the lock bolt (5) is parallel to the corresponding doorframe. The utility model has the advantages of simple structure, strong pick-proof performance, low cost, safety and practicality.
Description
Technical field
The utility model relates to security door.
Background technology
Existing security door generally is provided with a body, doorframe, and hinge, and the reciprocating motion by upper and lower strut drives the purpose that frame that each locking bolt reaches door reaches locking and opens door.This structure exists manufacturing process many, needs processing lock point in addition, and cost is higher, Installation and Debugging complexity, and pick-proof poor-performing.
Summary of the invention
The purpose of this utility model is to propose a kind of simple in structure, and pick-proof is strong, and cost is low, safe and practical security door.
The purpose of this utility model is realized by following technical scheme.
A kind of security door comprises doorframe (1), door body (3) lock core (7), and it is provided with connecting rod (2) or (22) are connected with lock core (7) by transmission mechanism, is provided with a locking bolt (5) on the connecting rod at least, and locking bolt (5) is parallel with corresponding doorframe.Doorframe (1) is provided with and the supporting keyhole (6) of locking bolt (5).Further, the utility model also can be at the upper and lower connecting rod (2) of respectively establishing of lock body (12), upper and lower connecting rod is provided with 1-10 locking bolt, locking bolt direction on the last connecting rod upwards, the locking bolt of lower link is directed downwards, lock core rotate to drive is gone up connecting rod and is protruded upward simultaneously that lower link stretches out downwards, also be provided with on the door body (3) pin seat (4) and with each tightening latch pivot bush unit.
The utility model also can be provided with connecting rod (22) on doorframe (1), be provided with a locking bolt (5) on the connecting rod at least, and locking bolt (5) is parallel with corresponding doorframe.Connecting rod (27) links to each other with lock body (12), and connecting rod (27) is provided with 1-10 locking bolt (5).Connecting rod (22) top is provided with top board (21), but rotating drivening rod (27), lock core moves up and down, and jack-up top board (21), be provided with locking bolt hole (6) at the edge of door body (3).
Description of drawings
Accompanying drawing 1 is embodiment 1 structural representation;
Accompanying drawing 2 is embodiment 2 structural representations.
Specific embodiment
Embodiment 1: as shown in Figure 1, lock body 12 is installed in the body 3, doorframe 1 flexibly connects by hinge and door body 3, be fixed with 4 locking bolts 5 that flexible direction is parallel with frame on the upper and lower connecting rod 2, and the upper and lower top of connecting rod is connected with straight bolt 11,10, on the corresponding position of a side of opening the door and locking bolt 5, be fixed with 4 keyholes 6 on the doorframe 1, keyhole 6 can be the circle that is fixed on the doorframe, also can be to curve a hole in the doorframe steel plate, can also be that two ends are fixed on the hole that is closed on the doorframe.Locking bolt 5 and be fixed on locking bolt seat 4 pivot bush units at a body edge, locking bolt seat 4 is provided with corresponding up and down hole, locking bolt 5 can be in the hole telescopic movable, it just in time can embed the keyhole 6 of projection on the doorframe up and down between hole.When opening the door, rotational lock core 7, transmission mechanism drive upper and lower connecting rod 2 and regain, and straight bolt on the lock body 12 and dead bolt are shunk, connecting rod 2 will go up straight bolt 11 and down straight bolt 10 extract keyhole up and down, locking bolt 5 shrinks with connecting rod 2, breaks away from keyhole 6, door is promptly opened.At closing time, backwards rotation lock core 7, transmission mechanism drive upper and lower connecting rod 2 and stretch out, go up in the keyhole of straight bolt 11 and down straight bolt 10 insertion doorframe top and the bottom, simultaneously, straight bolt and dead bolt on the lock body also stretch out, locking bolt 5 passes the keyhole 6 that is embedded in the locking bolt seat 4, and door is promptly shut.
Embodiment 2: as shown in Figure 2, door body 3 flexibly connects by hinge and doorframe 1, on in the door body 3, lower link 27 is connected with transmission mechanism on the lock body 12, and connecting rod 27 tops respectively are provided with straight bolt 11 and following straight bolt 10, doorframe 1 is provided with connecting rod 22 in a side of opening the door, be fixed with 4 locking bolts 5 on the connecting rod 22, the flexible direction of locking bolt 5 is parallel with corresponding doorframe, locking bolt seat 4 is fixed on the doorframe 1, locking bolt 5 and locking bolt seat 4 pivot bush units, locking bolt seat 4 is provided with corresponding up and down hole, locking bolt 5 can be flexible up and down in the hole, can embedding between the hole up and down of locking bolt seat 4 is fixed on a keyhole at body edge 6, and keyhole 6 can be the circle that is fixed on the body 1, can also be that two ends are connected the hole that is closed on the body.Connecting rod 27,22 and several fixed support 26 pivot bush units, it is just reliable that extension spring 28 makes connecting rod 22 move downward action, and top board 21 is connected with connecting rod 22.At closing time, rotational lock core 7, straight bolt and dead bolt that transmission mechanism drives on the lock body 12 stretch out the insertion keyhole, upper and lower connecting rod 27 stretches out simultaneously, upper and lower straight bolt 11,10 is also inserted in the hole of doorframe upper and lower part, straight bolt while jack-up top board 21 on it, thus the locking bolt 5 on the drivening rod 22 moves upward, pass the keyhole 6 that is embedded in the locking bolt seat 4, door i.e. locking.When opening the door, backwards rotation lock core 7, transmission mechanism is regained connecting rod 27 and straight bolt of lock body and dead bolt, connecting rod 27 makes upper and lower straight bolt 11,10 extract the keyhole of doorframe top and the bottom, top board 21 and connecting rod 22 move downward under the effect of gravity and spring 28, locking bolt 5 is withdrawal downwards thereupon also, decontrols the keyhole 6 that is embedded in the locking bolt seat 4, and door can be opened.
