Description

Multi-crosspiece and multi-insurance antitheft door

The utility model relates to the improvement of many lock bolts security door.

Existing safe-guard door lock, it is antitheft in order to improve for people, pick-proof, pick-proof ability, often emphasis is put on the structure of lock body, and ignores to some extent for the reliability of the door wing itself, therefore causes easily as long as destroying door cuts with scissors, and whole door lock just loses antitheft effect.At this problem, in conjunction with the structure of many lock bolts lock body, improve its lock bolt many and grow, stretching motion is not nimble etc. defective, at number of patent application: a kind of novel security door of proposition on 96236565.3 the basis.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of the multi-crosspiece and multi-insurance antitheft door that the wing is antitheft, crashproof, the pick-proof ability is strong, simple in structure, easy to manufacture is provided.

The technical solution of the utility model is as follows:

Multi-crosspiece and multi-insurance antitheft door comprises door leaf body, be loaded on the upper and lower long catch in the wing, round door, lock body, doorframe, door hinge etc., special feature is to be fixedly connected with short door bolt on the door leaf body of dress door hinge one side, and short door bolt exposes to a wing, and can with the corresponding joint in the door bolt hole on the doorframe.Further, lock body comprises Spring cylinder lock core, nine twin-lock cores of two spoons, and nine twin-lock cores of two spoons link by connector, make the flexible stroke of its dead bolt constraint Spring cylinder lock core.

Adopt such structure, the door wing is under the situation of locking, and short door bolt inserts in the door bolt hole of doorframe, even the door hinge is destroyed, Men Yi is locking safely still; And lock core interlock, be loaded in the door leaf body, hidden and safe and reliable.Make whole door wing structure firm, pick-proof, crashproof ability are strong.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A of Fig. 1 is to partial sectional view;

Fig. 3 is that the B of Fig. 1 is to partial sectional view;

Fig. 4 is the partial view of doorframe.

With reference to Fig. 1 and Fig. 4, present embodiment mainly by door leaf body 5, be loaded in the door leaf body 5 by the upper and lower long catches 11 of shifting block 9 interlocks, constitute with three circle door bolts 3 of hoodle dead bolt 19 interlocks and the oblique dead bolt 1 that drives by shifting part 2, doorframe 15, door hinge, lock body etc.Lock body has three lock cores and together retrains hoodle dead bolt 19, is respectively Spring cylinder lock core 7, nine twin-lock cores 6 of two spoons, and nine twin-lock cores 6 of two spoons are by middle hinged connector 17 interlocks.

Lock bolt was too much long in the past in order to overcome, it is not nimble to undo the lock, so rivet clasp has a plurality of short door bolts 10 on the door leaf body 5 of dress door hinge one side, quantity is decided on actual conditions, in this example be four, they all are exposed to outside the door leaf body 5, and with this side door frame 15 on door bolt hole 16 corresponding joints (as shown in Figure 4), the diameter in door bolt hole 16 is bigger than weak point door bolt 10, makes short door bolt 10 can insert door bolt hole 16 when Men Yi closes; And the door wing can not produce collision or friction with short door bolt 10 when opening.

The lock body of present embodiment is loaded on door leaf body 5 inside fully, in addition also constraint mutually of three lock cores.19 anterior and three circle door bolts, 3 interlocks (as shown in Figure 2) of hoodle dead bolt, the rear portion is then by pin 8 and shifting block 9 interlocks, under the drive of ball cylinder 14, the stretching motion of hoodle dead bolt 19 is realized closing or opening of the door wing, except that Spring cylinder lock core 7, the motion of hoodle dead bolt 19 also is subjected to dead bolt 18 constraints, when nine twin-lock cores 6 of two spoon under the clockwise rotating of key, dead bolt 18 moves up, and hinged connector 17 clockwise rotates (shown in arrow among Fig. 1), dead bolt 18 is extracted out from the hole of hoodle dead bolt 19, removes the restriction to hoodle dead bolt 19; Otherwise, be rotated counterclockwise, then with 19 lockings of hoodle dead bolt.

With reference to Fig. 1 and Fig. 3, the tapered end 14 of cylinder lock with balls, drive Spring cylinder lock cores 7 by dialing part 13, in case tapered end 14 is drilled from keyhole 4 by drill bit, Spring cylinder lock core 7 has just lost constraint, can arbitrarily open.For this reason, present embodiment locates all to be equipped with anti-drilling hard steel disc 12 at keyhole 4 and nine twin-lock cores 6 of two spoons (do not have among the figure and draw), and it can together rotate with keyhole 4, makes the structure of lock body more solid and reliable.
