Abstract
The utility model relates to a mechanism for locking an interlinking lever end of an intermediate lock of a theft-proof door, which belongs to the locking mechanism class controlled by an intermediate lock of the theft-proof door. The utility model uses a long connecting plate and a short supporting plate which are mutually fixed to form a frame through an upper fixing pin and two lower fixing pins, the two lower fixing pins in the frame are respectively sheathed with a concave rotating lock tongue, the middle parts of two lock tongues are respectively provided with a transverse spring seat hole, and the inner parts of two spring seat holes are respectively provided with a spring. The locking mechanism has the active effects of good anti-pick performance and high safety.
Description
The utility model belongs to the locking mechanism class of lock control in the security door.
Security door is in order to increase security performance, on door, be provided with middle lock, in lock by rotating mechanism make horizontal and upright to connecting rod stretch out, the end of each connecting rod is inserted in the hole on the doorframe locks door leaf and doorframe, 2 lockings, 4 lockings, 6 lockings, 8 lockings or the like are arranged at present, keyed end is many more, and security door is safe more.Each interlinking lever end is cylindrical or tetragonal latch at present, and pick-proof and safety are relatively poor.
The purpose of this utility model is: lock interlinking lever end locking mechanism in the security door of a kind of pick-proof and high safety is provided.
Technical measures of the present utility model are: adopt a long connecting plate and a short base plate; Long connecting plate interfixes into framework by last steady pin with two following steady pins with short base plate; Be with the rotating lock tongue of a spill on two following steady pins in framework respectively, the middle part of two dead bolts has a horizontal spring base hole respectively, and a spring is housed in two spring base holes.
In order to increase the convenience of use, a long limit pin hole is arranged in long connecting plate bottom.
Locking mechanism of the present utility model has good, the safe good effect of pick-proof.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a lateral view of the present utility model.
Drawing explanation and embodiment are as follows: 2 is long connecting plates among the figure, and the bottom of long connecting plate 2 can have a long spacing hole 9, and 1 is short base plate among the figure.Long connecting plate 2 interfixes into framework by last steady pin 3 with two following steady pins 8 with short base plate 1, is with the rotating lock tongue 5 of a spill on two following steady pins 8 in framework respectively.Two dead bolt 5 middle parts have a horizontal spring base hole respectively, and a spring 4 is housed in two spring base holes.6 is doorframes of security door among the figure, the 7th, and the door leaf of security door, the 10th, by the connecting rod of middle lock control.The lower end of long connecting plate 2 and connecting rod 10 interfix.Shown position is door leaf 7 and doorframe 6 mutual lock-out states.Under lock-out state, two dead bolt 5 open-shaped attitudes make security door be difficult for being pried open, and safety is greatly improved.When needs open the door, lock in the rotation, the rotating mechanism pulling connecting rod 10 of middle lock shrinks, long connecting plate 2 tape frames move down, two dead bolts 5 move down edge when contacting the lower edge of doorframe 6, at this moment two dead bolts 5 rotate around steady pin 8 down respectively inwards, and final jack from doorframe 6 falls and enters into door leaf 7, make door leaf 7 and doorframe 6 state that goes out of lock.
Claims (2)
1. lock the interlinking lever end locking mechanism in a security door, it is characterized in that:
A, a long connecting plate and a short base plate are arranged; Long connecting plate interfixes into framework by last steady pin with two following steady pins with short base plate;
Be with the rotating lock tongue of a spill on b, two the following steady pins in framework respectively, two dead bolt middle parts have a horizontal spring base hole respectively, and a spring is housed in two spring base holes.
2. by the described locking mechanism of claim 1, it is characterized in that: a long limit pin hole is arranged in long connecting plate bottom.
