The electric self-priming lock in the embodiment has the following working principle:
when the door lock is opened, as shown in fig. 1, the limiting block 7 is located on one side of the outer part of the tiger's mouth locking block 6, the linkage block 26 is contacted with the contact switch 14 to close the contact block, the contact piece 12 is contacted with the first contact of the rotary switch 11, and the controller receives a signal that the first contact of the rotary switch 11 and the contact switch 14 are both closed, so that the information that the door lock is in an open state at the moment is obtained.
When a door needs to be locked, a lock catch (not shown in the figure) on the door enters a tiger's mouth of the tiger's mouth lock block 6 along with the closing of the door, the inertia of the door drives the lock catch to touch and extrude the tiger's mouth lock block 6 to rotate around a rotating shaft C22 anticlockwise, the tiger's mouth lock block 6 rotates to drive a limiting block 7 tangent to one side of the tiger's mouth to rotate around a rotating shaft D24 clockwise, after the lock catch rotates to a certain radian, one side of the tiger's mouth lock block 6 can cross the blocking of the limiting block 7, the limiting block 7 can rotate to an initial position under the action of the rebound force of a fourth rotating part 25, and the tiger's mouth side of the tiger's mouth lock block 6 is abutted to prevent the tiger's mouth lock block 6 from rotating at the initial position, at the moment, the limiting block; when the first lock is carried out, the first jaw locking piece 6 can drive the contact column 10 to further drive the contact piece 12 to rotate anticlockwise around the rotating shaft C22, so that the contact piece 12 is separated from a first contact of the rotating switch 11 and rotates to be contacted with a second contact of the rotating switch 11, the controller receives a signal that the second contact of the rotating switch 11 is closed, controls the locking motor to rotate forwards, drives the gear piece 3 to rotate clockwise around the rotating shaft F16 through the output shaft 15 of the locking motor, drives the poking rod 5 on the gear piece 3 to rotate clockwise, rotates clockwise to be tangent to the first jaw locking piece 6 and extrudes the first jaw locking piece 6 to continue to rotate anticlockwise around the rotating shaft C22, when the other side of the first jaw locking piece 6 rotates to be tangent to the limiting block 7, extrudes the limiting block 7 again to rotate clockwise, and when the first jaw locking piece 6 rotates to a certain radian, the other side of the tiger's mouth can also cross the blocking of the limiting block 7, the limiting block 7 can rotate to the initial position again under the action of the resilience force of the fourth rotating part 25, and the other side of the tiger's mouth locking block 6 is supported at the initial position to prevent the tiger's mouth locking block 6 from rotating. At this time, the limiting block 7 is positioned on the other side of the outer part of the tiger's mouth locking block 6, which is equivalent to a second lock on the lock catch, as shown in fig. 3; in the second locking, the first-web lock 6 drives the contact post 10 to further link the contact piece 12 to continue to rotate counterclockwise around the rotating shaft C22, so that the contact piece 12 is separated from the second contact of the rotary switch 11 and rotates to contact with the third contact of the rotary switch 11, and the controller controls the locking motor to stop rotating after receiving a signal that the third contact of the rotary switch 11 is closed.
When the unlocking is needed, the controller controls the unlocking motor to rotate 180 degrees to pull a wire drawing (not shown in the figure) connected with the point A of the unlocking plate 8 to drive the unlocking plate 8 to rotate anticlockwise around the rotating shaft A17, because the unlocking plate 8 and the resisting block 4 are coaxially fixed, the anticlockwise rotation of the unlocking plate 8 drives the resisting block 4 to rotate anticlockwise around the rotating shaft A17, the resisting block 4 is separated from the poking rod 5, the poking rod 5 can rotate anticlockwise around the rotating shaft B under the action of the resilience force of the second rotating piece 21, the rotated poking rod 5 is separated from the resisting block 4, namely, the roller 19 is separated from the resisting block 4, and meanwhile, the roller 19 is also separated from the rotating shaft F16; then, the end of unlocking sheet 8 can drive linkage block 26 and then drive stopper 7 to rotate clockwise around rotation axis D24, make stopper 7 and tiger's mouth locking piece 6 separate, linkage block 26 and contact switch 14 separate simultaneously, tiger's mouth locking piece 6 then can be under the effect of the resilience force of third revolving part around rotation axis C22 clockwise rotation and resume initial condition, contact post 10 on tiger's mouth locking piece 6 also can drive contact piece 12 and revolve this moment, make contact piece 12 and rotary switch 11's third contact switch separate, and it contacts again to the first contact with rotary switch 11 to revolve, the intraoral hasp of tiger's mouth locking piece 6 can be followed the tiger's mouth at this moment and pulled out, realize the unblock, as fig. 4. After unlocking, the unlocking motor continues to rotate for 180 degrees to reset, and the drawn wire just resets.
After the unlocking motor is reset, the controller cannot receive a signal of the contact switch 14 and can receive a signal of a first contact of the rotary switch 11, the unlocking motor can be controlled to stop running, the unlocking plate 8 and the abutting block 4 can rotate clockwise around the rotating shaft A17 to an initial state under the action of resilience force of the first rotating member 29, the limiting block 7 can rotate anticlockwise around the rotating shaft D24 to an initial state under the action of resilience force of the fourth rotating member 25, and the linkage block 26 can be contacted with the contact switch 14 again; the controller receives a signal that the contact switch 14 is closed, and then controls the locking motor to rotate reversely, and then the locking motor stops when the output shaft 15 of the locking motor drives the gear piece 3 to rotate clockwise around the rotating shaft F16 to the initial state, the poking rod 5 on the gear piece 3 also rotates clockwise along with the gear piece 3, the tail end of the poking rod can be blocked by the poking piece 13 fixed on the base 1, so as to ensure that when the gear piece 3 rotates to the initial state, the poking rod 5 just reaches the initial state, the roller 19 at one end of the poking rod 5 just coaxially with the rotating shaft F16 of the gear piece 3 again, the whole device recovers to the initial state, and waits for the next locking action, as shown in fig. 1.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
