Folded connection, the two can rotate synchronously.
Specifically, the first cam 25 includes long wheelbase edge 27 and small wheelbase edge 28；When long wheelbase edge 27 pushes
When the first side arm 22 of latch hook 4, the interconnecting piece 20 of the release lock push plate 3 of locking structure 23 of latch hook 4.When the small axis of the first cam 25
When away from edge 28 towards latch hook 4, latch hook 4 rotates counterclockwise under the affecting of the second extension spring 19, and by 23 hook of locking structure
The interconnecting piece of padlock push plate 3.Second cam 26 is provided with bulge-structure 29, and when 29 pushing tow of bulge-structure locks push plate 3, lock is pushed away
Plate 3 rotates counterclockwise certain angle, and discharges bolt plate 2, allows being rotated by spring assembly 6 of bolt plate 2,
Into unlocking condition.
The shaft of two-tiered cam 5 is mounted in the mounting hole 30 of substrate 1, and the other side of mounting hole 30 is provided with stepper motor
(not shown).Stepper motor controls unlocking and the latching process of jam plate for driving two-tiered cam 5 to rotate.
As shown in Fig. 1,3,4, it is additionally provided with first stroke switch 31 and second stroke switch 32 in the front of substrate 1,
First stroke switch 31 is used to detect the open state of bolt plate 2, when bolt plate 2 is in blocking, first stroke switch
31 disconnect, and when bolt plate 2 is in the open state, bolt plate 2 touches first stroke switch 31, so that first stroke switch 31 is led
It is logical.Second stroke switch 32 is used to detect the stroke state of latch hook 4；When latch hook 4 locks lock push plate 3, second stroke switch 32
It disconnects, when latch hook 4 discharges lock push plate 3, the second side arm 24 of latch hook 4 touches second stroke switch 32, so that second stroke is opened
Close 32 conductings.First stroke switch 31 and second stroke switch 32 are electrically connected with the controller of stepper motor.Stepper motor
Controller for control stepper motor rotation.
As shown in Figure 1, 2, the first wheel shaft 8 and the second wheel shaft 18 are also connected with backplate 33；Backplate 33 is parallel with substrate 1, lock
Hyoplastron 2 and lock push plate 3 are in the gap between substrate 1 and backplate 33.It is led when because of corrosion, the excessively low factor of part processing precision
When the first wheel shaft 8 or the second wheel shaft 18 being caused to loosen, backplate 33 can prevent bolt plate 2 and lock push plate 3 to be staggered, and jam plate is caused surprisingly to be opened
Lock.The edge of backplate 33 is provided with the first retention bead 36 and the second retention bead 37.It is provided in bolt plate 2 and the first limit
Raised 36 compatible first limited posts 38 in position, the first limited post 38 can cooperate with the first retention bead 36, prevent bolt plate 2 from existing
Inordinate rotation during unlocking.It locks and is provided with second limited post 39 compatible with the second retention bead 37 in push plate 3, second
Limited post 39 can cooperate with the second retention bead 37, prevent lock lock 3 inordinate rotation of push plate.
As shown in Fig. 1 to 7, the present embodiment further relates to the method for switching of shock resistance jam plate, this method include unlocking process with
And latching process, in which:
As shown in Figure 1, 2, 3, during unlocking, two-tiered cam 5 rotates counterclockwise.In rotary course, two-tiered cam 5
The first cam 25 the pushing tow latch hook 4 first of long wheelbase edge 27 so that latch hook 4 release lock push plate 3；Subsequent two-tiered cam 5
29 pushing tow of bulge-structure of second cam 26 locks push plate 3, so that the limiting section 15 of lock push plate 3 discharges the hook portion of bolt plate 2, releases
It puts rear bolt plate 2 to rotate counterclockwise under the driving of spring assembly 6, bolt plate 2 touches first stroke switch 31, indicates jam plate
It fully opens, after controller detects that first stroke switch 31 is connected, controller control stepper motor stops operating.
As shown in Fig. 1,2,4, in latching process, user is pushed the locking edge 11 of bolt plate 2 using locking bar 13, is driven
Dynamic bolt plate 2 rotates (clockwise direction in Fig. 1) to the direction of lock push plate 3, and the hook portion of bolt plate 2 14 is fastened on lock
On the limiting section 15 of push plate 3.In latching process, locking bar 13 pushes bolt plate 2 to leave first stroke switch 31, first stroke
Switch 31 enters off-state, and after controller detects that first stroke switch 31 disconnects, control stepper motor rotates two-tiered cam
5, latch hook 4 is sprung back under the driving of spring assembly 6.After latch hook 4 is sprung back, the locking structure 23 of latch hook 4 fixes lock and pushes away
The interconnecting piece 20 of plate 3, so that lock push plate 3 can not discharge bolt plate 2.When latch hook 4 starts rebound, the second side arm of latch hook 4
24 leave second stroke switch 32 completely, so that second stroke switch 32 disconnects, after detecting that second stroke switch 32 disconnects, control
Device processed stops driving stepper motor rotation, and jam plate is completely into lock state.When being in the lock state, the locking hook of bolt plate 2
10 are enclosed the closedown structure 12 of annular with the locking bar receiving notch 7 of substrate 1, so that being plugged in the locking bar in closedown structure 12
Closedown structure can not be detached from.
When being in the lock state, bolt plate 2 is locked by lock push plate 3, and is locked push plate 3 and locked by latch hook 4.In this way
It can be opened to avoid when being stirred when lock is by side impact and by people's malice with thing, effectively improve the safety of jam plate
Property.
Above the utility model embodiment, does not constitute the restriction to scope of protection of the utility model.It is any this
Made modification, same replacement and improvement etc., should be included in the protection of the utility model within the spiritual and principle of utility model
Within the scope of.
