Abstract

The utility model relates to a rotating lock rod type anti-theft door, comprising a door leaf body 1, a door lock 2, a lock rod 3, a lock rod 4, a draw rod 5, a draw strip 6 and a pendulous body 7. Two lock rods can rotate around a fixed shaft; the lock rod can be drawn to rotate by that the draw strip moves up and down under the action of the lock 2, and thus the lock rod extends out or withdraws into the door leaf body; the pendulous body plays a braking action on the lock rod. The utility model realizes that after the door is locked, the whole door leaf body is stressed by the lock rod, increasing the fast degree of the door; when the door lock 2 is destroyed, two lock rods can automatically rotate to be flat to lock the door.

Description

The novel anti-theft door

The utility model relates to a kind of security door, definite a kind of security door that is equipped with rotary locking bar of saying so.

Security door of the prior art, still the Multiple locking point of monolock point but lock all is installed in the part of door leaf, make the door of locking local to be subjected to the power of locking bar, see on the whole lock the door with regard to firm degree not enough, and security door of the prior art is in case suffer damage or ruin lock by force when door lock, lock just is easy to open so, that is to say that " lock is ruined door and opened " is the common drawback of security door in the prior art.

The purpose of this utility model provides a kind of like this security door: whole door leaf body all is subjected to the power of locking bar after locking by rotary locking bar realization door, and this meeting is automatically locked after door lock is subjected to destroying by force.

The purpose of this utility model is to realize by such mode, and a kind of security door that has rotary locking bar comprises door leaf, two locking bars, pull bar, lock body, tie rod, hypophysis.Two locking bars are fixed in the door leaf body by fixed axis, and can rotate around the axis, the door leaf side has four slotted eyes so that contracting of locking bar stretched, with also have four slotted eyes on the corresponding doorframe of the slotted eye on the door leaf, two locking bars link to each other to reach the purpose of mutual braking by pull bar, door lock is flexible by tie rod control locking bar, and hypophysis also is used for locking bar is played braking action.

Below in conjunction with the drawings and specific embodiments the utility model is described in further details.

Fig. 1 is an extremely inner body structure chart of door leaf.

Fig. 2 is the cut-away view of door lock.

Fig. 3 A is the elevation of tie rod, the left view that B is tie rod.

As shown in Figure 1,1 is the door leaf body, 2 is door lock, 3 and 4 is locking bar, 5 is pull bar, 6 is tie rod, 7 is hypophysis, the door leaf right side is fixed on the doorframe by axis body, locking bar 3 and 4 centre have a fixed axis to pass respectively, make two locking bars to rotate around fixed axis, thereby realize locking bar indentation door leaf body or stretch out, locking bar 3 is connected by pull bar 5 with 4, thereby realize that the rotation of locking bar 4 drives the rotation of locking bar 3, to drive locking bar 4 when drawing on the tie rod 6 sways and causes locking bar 3 at last, 4 indentation door leaf body, door unblanks to finish, because the action of gravity meeting of hypophysis 7 makes last two locking bars of locking bar 4 backward rotation stretch out the door leaf body, door is locked and is finished when tie rod 6 moves downward.

As shown in Figure 2, the gear 9 that has balanced handle, pulling block formula lock 8, swing to gear 11, spragging gear 12, brake shrapnel 13, the prominent head of shifting block lock 8 puts in the slot of gear 9 when door is in locking state, thereby stop the rotation of all gears, when looking on the bright side of things door, at first open pulling block type lock 8 with key, 8 prominent head withdrawal clockwise rotates soccer star's handle 10 with hand then, thereby driven gear 9 rotates, the rotation of gear 9 is swung to gear 11 with drive and is rotated counterclockwise, because it is that tooth bar is strong that tie rod 5 puts in the part of lock 2 inside, so the rotation of gear 11 will cause moving up and down of tie rod 5, driven gear 12 is rotated in the rotation of gear 9, because the effect of braking flexure strip 13 will overcome the effect of the drop-down locking bar of hypophysis 7, but also the feel when having increased turning handle.

As shown in Figure 3, there are two staples to pass in the front slotted eye of tie rod 6, to guarantee that tie rod moves up and down by vertical track, locking bar 4 passes from the side slotted eye of pull bar 6, when door lock 2 is damaged, tie rod 5 can split away off from locking 2, lock thereby locking bar 3,4 can stretch out to door automatically, even so door lock to be ruined door also be to be difficult to open.What this exteriorly gave the people feels it is 4 lockings, and the lock that also can install other as required in the door leaf left side is to increase the lock point.
