Abstract
The invention relates to a composite-mechanism fire-fighting lock which is characterized by having composite-mechanism unlocking functions like key unlocking, door control electromagnet unlocking and pushing rod unlocking, also being provided with an electronic micro switch to feed back the opening and closing states, and facilitating centralized or remote management. When a key is used for unlocking, the key directly drives a mechanical unlocking plate to unlock. When a door control electromagnet is used for unlocking, an electromagnet component is powered to attract the unlocking plate to enable a lock tongue to retract to unlock. When a pushing rod is used for unlocking, the pushing rod is pressed down to drive a floating sliding block to move downwards, through the inclined plane action of the floating sliding block, a sliding positioning pin is made to move backwards along the inclined plane, a pulling rod also moves backwards at the same time under the action of a drive spring, and due to the fact that one end of the pulling rod is connected with the unlocking plate, the unlocking plate is also driven to move backwards to achieve the unlocking function. In addition, the composite-mechanism fire-fighting lock is further characterized in that the floating sliding block with the inclined plane is used to achieve the unlocking function. The composite-mechanism fire-fighting lock has the advantages that the lock tongue is prying resistant, safety and reliability are achieved, and operation and control performance is good.
Description
Technical field
The present invention relates to a kind of fire-fighting lock.
background technology:
Existing fire-fighting lock pusher structure is all quadric chain substantially, and patent document CN201011240Y proposes a kind of new pusher structure, is intended to solve fire-fighting lock push rod, table cover and door handle and mutually interferes, be sometimes not easy the problem opening door.Patent document CN2477773Y proposes a kind of electric fire-fighting lock, is connected with fire-fighting linkage system, when main purpose is breaking out of fire, utilizes fire fighting system to be opened by door from outside by electronic mode.
Have at present the fire-fighting lock of two types on the market, a kind of is take 230D as the fire-fighting lock of representative, and be characterized in that lock and unlock all must come with key, the push rod that can promote when there is fire alarm to lock unlocks, and lock body internal alarm is reported to the police simultaneously.Another kind take V40 as the push rod lock of representative, and what solve front a kind of lock during its feature can not automatic locking problem, but dead bolt not pick-proof, there is no gate inhibition's unlocking function.
summary of the invention:
The object of this invention is to provide composite structure fire-fighting lock.
Composite structure fire-fighting lock of the present invention, is made up of push rod (1), floating slider (2), location jump ring (3), back-moving spring (4), locating support (5), slide jaw (6), pull bar (7), jump ring (8), driving spring (9), fine motion electronic switch (10), unlocking board (11), electromagnet assembly (12) and lock body (13) parts.Push rod (1) in the top of floating slider (2), and is connected on lock body (13) and can moves up and down; Floating slider (2) is by the waist-shaped hole (14) above it, through pull bar (7), limit it by location jump ring (3) to move left and right, in the bottom of floating slider (2), back-moving spring (4) is housed, the bottom of back-moving spring (4) is arranged on locating support (5), and back-moving spring (4) can make floating slider (2) reset; Pull bar (7) there is cross-drilled hole (15), slide jaw (6) coordinates with cross-drilled hole (15), one end of pull bar (7) is connected with unlocking board (11) by jump ring (8), circular hole (16) matched in clearance on its other end and locating support (5), makes pull bar (7) can side-to-side movement; Driving spring (9) is enclosed within pull bar (7), spacing by slide jaw (6); Fine motion electronic switch (10) is arranged on lock body (13), and the end face of close pull bar (7), by detecting fine motion electronic switch (10) and the distance of pull bar (7) end face, judge the open and-shut mode locked; Electromagnet assembly (12) is arranged on lock body (13), and near unlocking board (11), when electromagnet assembly (12) powers on, its adhesive unlocking board (11) unlocks, and realizes locking function during power-off.
Described composite structure fire-fighting lock, when locking, cam (19) of locking drives connecting rod (20) to drive clamping kit (25), make clamping kit (25) and unlocking board top board (22) and mutually realize self-locking between unlocking board top board (22) and unlocking board (11), because clamping kit (25) is connected with oblique dead bolt (21) assembly, oblique dead bolt (21) pushes away motionless from outside, also just achieve the tamper-resistant function of oblique dead bolt (21).During unblock, unlocking board (11) and unlocking board top board (22) are thrown off, and unlocking board top board (22) loses the strong point, and just throw off with clamping kit (25), oblique dead bolt (21) can move backward and realize unlocking function.
Described composite structure fire-fighting lock, has key unblock, gate inhibition's electromagnet unlocks and push rod unlocks composite structure unlocking function.When unlocking with key, unlock with key driven cylinder runner (23) driving device unlocking board (24); When unlocking with gate inhibition's electromagnet, electromagnet assembly (12) powers on, adhesive unlocking board (11), makes dead bolt retract and unlock.
Described composite structure fire-fighting lock, by lower push-rod (1), push rod (1) drives floating slider (2) to move down, due to the effect on the inclined-plane (17) of floating slider (2), slide jaw (6) is moved backward along inclined-plane (17), and pull bar (7) also moves, because one end of pull bar (7) is connected with unlocking board (11) under the effect of driving spring (9) simultaneously backward, thus drive unlocking board (11) also to move backward, realize unlocking function.After unclamping push rod (1), floating slider (2) moves upward under the promotion of back-moving spring (4), slide jaw (6) is moved forward along inclined-plane (17), pull bar (7) promotes unlocking board (11) and also moves forward, due to the effect of the upper vertical plane (18) of floating slider (2), define slide jaw (6) to move backward, also just define unlocking board (11) and move backward, realize locking function.
Described floating slider (2), has inclined-plane (17) above it, spacing for slide jaw (6); There is a waist-shaped hole (14) at middle part, for through pull bar (7), is also convenient to floating slider (2) simultaneously and moves up and down.

detailed description of the invention:
Now the invention will be further described with example by reference to the accompanying drawings.
When locking, cam of locking (19) first moves, and promotes connecting rod (20) and whole mechanism is moved backward.When oblique dead bolt (21) encounters the hole on doorframe, under spring force, oblique dead bolt (21) inserts corresponding hole, realizes locking function.In the case, unlocking board (11) and unlocking board top board (22), A1, A2, A3 tri-regions between clamping kit (25) and unlocking board top board (22) shown in Fig. 8 realize self-locking, prevent from prizing oblique dead bolt (21) and unlocking.
During unblock, can be unlocked by key, gate inhibition's electromagnet unlocks and push rod unblock etc.
When unlocking with key, unlock with key driven cylinder runner (23) driving device unlocking board (24).
When unlocking with gate inhibition's electromagnet, electromagnet assembly (12) powers on, adhesive unlocking board (11), makes dead bolt retract and unlock.
Push rod unblock is unlocking function from inside to outside, when mainly containing burst fire, only need by lower push-rod (1), push rod (1) drives floating slider (2) to move down, due to the effect on the inclined-plane (17) of floating slider (2), slide jaw (6) is moved backward along inclined-plane (17), pull bar (7) also moves under the effect of driving spring (9) simultaneously backward, because one end of pull bar (7) is connected with unlocking board (11), thus drive unlocking board (11) also to move backward, realize unlocking function.
This lock good looking appearance, pick-proof, simple installation, be applicable to the installation of various passageways for fire apparatus door.
