As depicted in figs. 1 and 2, which locks, including lock housing 1, locking bar 2, sled mechanism 3, pin plate mechanism 4 and unlock
Plectrum 5, sled mechanism 3 are slidably mounted on lock housing 1, and pin plate mechanism 4 is slidably mounted on locking bar 2, pin plate mechanism 4 and sled mechanism 3
Lean cooperation, and locking bar 2 is equipped with the step 21 for the cooperation that leans with sled mechanism 3, and unlock plectrum 5 is used to stir sled mechanism 3.
Locking bar 2 is two, and two locking bars 2 are equipped with the step 21 for the cooperation that leans with sled mechanism 3, and pin plate mechanism 4 is slidably mounted on
One of two locking bars 2.
Sled mechanism 3 includes slide plate 31 and skateboard spring 32.The end of slide plate 31 is equipped with baffle 33 and shifting block 34, slide plate
31st, baffle 33 and shifting block 34 are an integral molding structure.The step 21 of baffle 33 and locking bar 2 leans cooperation, and shifting block 34 is with unlocking
Plectrum 5 matches.Skateboard spring 32 is torsional spring.One end of skateboard spring 32 is installed on lock housing 1, and the other end is connected with slide plate 31.
When unlock plectrum 5, which stirs shifting block 34, lifts slide plate 31, baffle 33 and the step 21 of locking bar 2 are detached from, and locking bar 2 is removable.When
When slide plate 31 is fallen, baffle 33 and the step 21 of locking bar 2 offset, and limit the movement of locking bar 2.
Lock housing 1 is mounted by means of screws with installing plate 11.Installing plate 11 is equipped with the first locating rod 12, the first locating rod 12
For screw.Slide plate 31 is provided with the first sliding groove 35, and the first locating rod 12 is located in the first sliding groove 35.
Pin plate mechanism 4 includes pin plate 41 and pin plate spring 42.Pin plate 41 is equipped with plug 43, and plug 43 can be inserted into 31 bottom of slide plate
Between end and lock housing 1.Pin plate 41 and plug 43 are an integral molding structure.Pin plate spring 42 is torsional spring.One end of pin plate spring 42
Locking bar 2 is installed on, the other end is connected with pin plate 41.When slide plate 31 lifts, plug 43 be inserted into 31 bottom end of slide plate and lock housing 1 it
Between, locking bar 2 is removable.Plug 43 is exited between 31 bottom end of slide plate and lock housing 1, and slide plate 31 is fallen, and limits the movement of locking bar 2.
Locking bar 2 is equipped with the second locating rod 23, and the second locating rod 23 is screw.Pin plate 41 is provided with second sliding slot 44, and second is fixed
Position bar 23 is located in second sliding slot 44.
As shown in figure 3, the outside of lock housing 1 is equipped with knob 13 and safe driving lever 14.Knob 13 is sequentially connected with locking bar 2, rotation
Button 13 can drive locking bar 2 to move, and locking bar 2 is made to complete unlocking and locking action.Safe driving lever 14 connects with the unlock transmission of plectrum 5
It connects.Safe driving lever 14 is stirred, can swing unlock plectrum 5, so as to complete operation of the unlock plectrum 5 to sled mechanism 3.
Locking bar 2, knob 13, the first lock core 7 of the fire-fighting door lock of present embodiment are sequentially connected with transmission gear.Transmission
Gear is as shown in dotted line in Fig. 1 and Fig. 2.Lock housing 1 is also provided with locking button 15, and button 15 is locked in rotation, makes the first lock core 7 and transmission
Gear is detached from, and the first lock core 7 is ineffective, and key can not then open lockset outdoors, play safety effect.
As shown in Figure 4 and Figure 5, the security against fire lock of present embodiment further includes locking closure 6, the first lock core 7 and the second lock core
8, the first lock core 7 and the second lock core 8 are mounted on locking closure 6.First lock core 7 is sequentially connected with locking bar 2, the second lock core 8 and unlock
Plectrum 5 matches.Second lock core 8 is provided with cam 81, and unlock plectrum 5 is L-shaped piece, and cam 81 coordinates with L-shaped piece, it can be achieved that solving
Lock the swing of plectrum 5.
The unlocking of the security against fire lock of present embodiment and locking process are：
Fig. 1 is the locking state of security against fire lock.Shutter door is locked at this point, locking bar 2 stretches out, slide plate 31 is in and falls shape
State, step 21 and the baffle 33 of locking bar 2 offset, and limitation locking bar 2 moves, and 13 or first lock core 7 of knob can not move locking bar 2.
Fig. 2 is the unlocking condition of security against fire lock.Safe 14 or second lock core 8 of driving lever swings unlock plectrum 5, and unlock is dialled
Piece 5 offsets with shifting block 34, stirs slide plate 31, and slide plate 31 lifts, and gap occurs between 31 bottom end of slide plate and the bottom surface of lock housing 1, pin
Plate 41 is mobile under the action of pin plate spring 42 to make plug 43 be inserted between 31 bottom end of slide plate and the bottom surface of lock housing 1 so that slide plate
31 in lifting state.Due to lifting for slide plate 31, baffle 33 allows open position for the step 21 of locking bar 2, passes through knob 13 or the
One lock core 7 moves locking bar 2.
When 13 or first lock core 7 of knob moves locking bar 2, pin plate 41 is moved with locking bar 2, and plug 43 is from 31 bottom end of slide plate
It is extracted out between the bottom surface of lock housing 1, slide plate 31 is automatically fallen off under the action of skateboard spring 32, therefore, is also needed when unlocking again
Pull unlock driving lever 5.
Therefore, the security against fire lock of present embodiment needs two keys, but when locking outdoors when unlocking outdoors, only
Need a key.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to the protection model of the present invention
It encloses.
