The large side lock bar (11) adopts a rectangular tube, and the large side lock transmission mechanism (9) is connected with a large side lock bar (11) through a sunk screw (10). The lock can ensure that a door leaf (3) is connected with a lock quadrate door frame (13) into a whole vertically to realize the overall locking.
Description
One, technical field
The utility model relates to a kind of security door locking device, is specially the big limit lock that is used for the steel security door.
Two, background technology
Before this, the inventor once obtained a kind of utility model patent of Lock for theft-proof door, its publication number is CN01206404.1, the major technique feature of this patent is to have direction recess and fore shaft groove relatively at door leaf and doorframe cork cot, jam plate is housed in direction recess, be fixed with the axis of guide on jam plate, the axis of guide passes axis hole recoil on the door leaf on support, is provided with the changement that drives the axis of guide between the axis of guide and lock core.This Lock for theft-proof door makes lock realize the face locking by jam plate, thereby has strengthened the pick-proof performance of security door greatly.But, in use find the complex structure of this big limit lock, cost height.
Three, summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, designs the big limit lock of security door a kind of simple in structure, with low cost.
The utility model is achieved through the following technical solutions:
A kind of Lock for theft-proof door, it is characterized in that comprising tripartite mortise handle lock with main dead bolt, tripartite mortise handle is locked and is provided with the underdrive shift fork, last underdrive shift fork is connected in an end of world lock kinematic link, the other end of world lock kinematic link is connected on the lock of the world, be connected with big limit lock transmission mechanism shift fork on the lock kinematic link of the world, big limit lock transmission mechanism shift fork is connected with big limit lock transmission mechanism, and big limit lock transmission mechanism is connected with a big limit lock bolt.In fact described big limit lock transmission mechanism is exactly changement, its operating principle is, when big limit lock transmission mechanism shift fork moves up and down with world lock kinematic link, big limit lock transmission mechanism shift fork also moves up and down synchronously, by mechanism's conversion of lock transmission mechanism inside, big limit, just make the big limit lock bolt move left and right that is connected with big limit lock transmission mechanism.Mechanism's conversion of lock transmission mechanism inside, big limit can have multiple mode to realize, as cam mechanism, sliding-block linkage etc., when adopting sliding-block linkage, big limit lock transmission mechanism shift fork is equivalent to connecting rod, big limit lock bolt is equivalent to controlled slide block that can only translation, and rod hinge connection is on slide block.
Further scheme is: big limit lock bolt is a rectangular tube, and big limit lock transmission mechanism is connected with big limit lock bolt by sunk screw.
Advantage of the present utility model: compare with the CN01206404.1 patent, the utility model will be locked the dial lock and make tripartite mortise handle lock into, plate is turned in commutation made more simple big limit lock transmission mechanism into, the axis of guide is originally also replaced by big limit lock transmission mechanism, thereby structure is more simple, uses more reliable; Made original solid big limit lock bolt into quality more light and handy hollow rectangle pipe, more laborsaving during the switch lockset.
Four, description of drawings
Fig. 1 is the cross-sectional view with the security door of big limit lock, also is the A-A sectional view of Fig. 2.
Fig. 2 is the partial sectional view of door leaf, also is the B-B sectional view of Fig. 3.
Fig. 3 is the partial enlarged drawing of the door leaf side of lock cross section.
Among the figure: 1, the side's of hinge doorframe, 2, door hinge, 3, door leaf, 4, tripartite mortise handle lock, 5, tripartite mortise handle lock pin, 6, big limit lock transmission mechanism shift fork, 7, go up the underdrive shift fork, 8, direction recess, 9, big limit lock transmission mechanism, 10, sunk screw, 11, big limit lock bolt, 12, the locked groove mouth, 13, the side's of lock doorframe, 14, world lock, 15, world lock kinematic link.
Five, the specific embodiment
Below in conjunction with accompanying drawing the utility model is done detailed description.
As Fig. 1 to Fig. 3, a kind of Lock for theft-proof door, it is characterized in that comprising tripartite mortise handle lock 4 with main dead bolt, tripartite mortise handle lock 4 is provided with underdrive shift fork 7, last underdrive shift fork 7 is connected in an end of world lock kinematic link 15, the other end of world lock kinematic link 15 is connected on the world lock 14, on world lock kinematic link 15, be connected with big limit lock transmission mechanism shift fork 6, big limit lock transmission mechanism shift fork 6 is connected with big limit lock transmission mechanism 9, and big limit lock transmission mechanism 9 is connected with a big limit lock bolt 11.
Big limit lock bolt 11 is rectangular tubes, and big limit lock transmission mechanism 9 is connected with big limit lock bolt 11 by sunk screw 10.
From Fig. 1 to Fig. 3 as can be seen, when this Lock for theft-proof door is used for security door, twist tripartite mortise handle lock pin 5 at closing time, last underdrive shift fork 7 upwards, following direction is stretched out and is promoted world lock kinematic link 15 upwards, following direction motion, the big limit lock transmission mechanism shift fork 6 that meanwhile is connected with world lock kinematic link 15 also and then upwards, following direction motion, big limit lock transmission mechanism 9 is stretched out outside door leaf 3, thereby the big limit lock bolt 11 that is connected with big limit lock transmission mechanism 9 is stretched out in the locked groove mouth 12 on the lock side's doorframe 13 of going forward side by side outside door leaf 3, when tripartite mortise handle lock 4 is in full lock and closes, world lock 14 will stretch on the doorframe 13, in the lockhole of below.And this moment big limit lock bolt 11 a part enter in the locked groove mouth 12 on the lock side doorframe 13, and another part of big limit lock bolt 11 is still stayed in the direction recess 8 of door leaf 3 door leaf 3 and lock side doorframe 13 linked together from top to bottom and is realized comprehensive the locking.The direction of motion when opening the door is just opposite with the direction of motion at closing time.
