The components of the lock plate are shown in fig. 3, and the structure thereof is shown in fig. 1 and 2.

An electric impact-resistant anti-theft bayonet-type lock plate, comprising: the lock comprises a lock bottom plate 1, a rotating piece 11, a lock tongue hole notch 2, a torsion spring 3, a bayonet lock piece 4, a bayonet lock piece pressing plate 5, a microswitch 6, a rotating shaft 7, a cam 8, a tension spring 9 and a motor 10.

The rotating sheet 11 is connected to the lock bottom plate 1 through the rotating shaft 7, and the lock bottom plate 1 is provided with a first notch 2. The rotating piece 11 is provided with a second gap, the upper jaw and the lower jaw of the second gap can be combined with the first gap 2 to form a lock tongue hole, and the rotating piece 11 is additionally provided with a concave part. The torsional spring 3 suit is in pivot 7, and the hook portion of the one end and the lock bottom plate side of torsional spring 3 is connected, and the other end is connected with the chin of 11 second breachs of revolving fragment. The bayonet lock piece 4 is connected with the lock bottom plate through the tension spring 9, the pin head of the bayonet lock piece 4 is matched with the depressed part of the rotating piece 11, so that the abnormal counterclockwise rotation unlocking of the rotating piece 11 is limited after the locking is closed, and the safety effect is achieved. The first side of the bayonet lock piece 4 is provided with a first bayonet lock piece bulge, and the first bayonet lock piece bulge receives the action of external force to drive the pin head of the bayonet lock piece 4 to move telescopically. The lock base plate 1 is provided with a motor 10, the motor 10 is connected with a cam 8, and the cam 8 is provided with a cam boss. As motor 10 rotates, the cam lobe pushes against the first bayonet tab lobe of bayonet tab 4. The second side of the clamping pin sheet 4 is provided with a second clamping pin sheet protruding part, the lock bottom plate is provided with a microswitch 6, and along with the movement of the clamping pin sheet 4, the second clamping pin sheet protruding part is in contact with or disconnected from the microswitch 6 to send an opening and closing signal.

The locking plate further comprises a clamping pin sheet pressing plate 5, the clamping pin sheet pressing plate 5 is fixed on the locking bottom plate 1 through screws, and the clamping pin sheet 4 is movably arranged between the locking bottom plate 1 and the clamping pin sheet pressing plate 5. The upper part of the bayonet lock piece pressing plate 5 is provided with a pressing plate convex part, the tail end of the bayonet lock piece 4 is provided with a third bayonet lock piece convex part, one end of the tension spring 9 is connected with the third bayonet lock piece convex part, and the other end of the tension spring 9 is connected with the pressing plate convex part. The bottom of the clamping pin piece pressing plate 5 is provided with four accommodating columns for accommodating screws, a square groove space (not shown in the figure) is formed between the four accommodating columns and the bottom plate, the inner diameter of the square groove is closer to the outer diameter of the clamping pin piece 4 main body, and a few gaps are reserved between the four accommodating columns and the clamping pin piece so that the clamping pin piece can only move along the axis direction of the square groove without shaking when being acted by the tension spring 9 or the cam bulge part, and the movement is very stable. And because the main part of bayonet lock piece 4 is injectd on bayonet lock piece clamp plate 5 for first bayonet lock piece bellying, the card of second bayonet lock piece bellying are established four of square groove and are held the appearance of establishing the screw and establish the post, thereby have restricted the bayonet lock piece and have removed in left and right directions, make the bayonet lock piece can only follow the axis direction flexible removal of square groove under the effect of cam, accomplish opening and close of insurance.

The working principle and the method of the locking plate are as follows:

the lock plate and the lock tongue are not locked by the traditional hook type lock, but are changed into a rotating piece, a bayonet lock piece and the lock tongue which are matched, so that the function of locking and safety is achieved.

When the locking plate is in a closed state, the lock tongue (not marked) blocks the position of the first notch 2 of the lock tongue hole, and locking is finished. The bayonet lock piece 4 provides supporting force through the bayonet lock piece pressing plate 5 locked on the lock bottom plate 1, and after the lock is closed, the pin head of the bayonet lock piece 4 is clamped in the depression of the rotating piece 11, so that the rotating piece 11 is limited to rotate anticlockwise under abnormal acting force to cause abnormal unlocking, and the effect of safety and theft prevention is achieved.

The locking plate is normally in a closed state, when the locking plate receives a code scanning or other opening signal, the motor 10 rotates anticlockwise, the cam 8 drives the first bayonet piece protruding part of the bayonet piece 4 to move outwards along the axis direction of the bayonet piece pressing plate 5, and therefore the pin head of the bayonet piece 4 is separated from the sunken part of the rotating piece 11, and the safety state is relieved. At this moment, micro-gap switch 6 and bayonet lock piece 4 stretch out the contact closure of second bayonet lock piece bellying, and the motor continues to rotate, and simultaneously, the spring bolt (not sign) is retracted and is broken away from the dead bolt hole, and revolving fragment 11 can be at the effect anticlockwise rotation of torsional spring 3 to the lock is opened, and the round pin head of bayonet lock piece 4 inwards retracts and resets along the axis direction of bayonet lock piece clamp plate 5 under the effect of extension spring 9, and support the peripheral arc border of 11 depressed parts of revolving fragment, make revolving fragment 11 stop in the open position. After the bayonet 4 resets, micro-gap switch 6 breaks away from with bayonet 4 and stretches out second bayonet lug boss, and micro-gap switch 6 disconnection, motor stall this moment accomplishes whole action of unblanking.

When needing to close the lock, the spring bolt stretches out first breach 2 to spy the second breach of straightening revolving fragment 11, the chin of this second breach is pressed down perpendicularly, because pressurized point and fixed axle 7 are eccentric design, revolving fragment 11 can revolute 7 rotations of rotating shaft, when pressing to a certain extent, the effect of ending the position can be played to the degree of depth of 1 opening 2 of locking bottom plate, and at this moment, the round pin head of bayonet lock piece 4 can fall in the sunken of revolving fragment 11 again, blocks revolving fragment 11. And the bayonet 4 can be pressed again and leave the microswitch 6 (simultaneously unlocking) in the process of finishing the action, when the bayonet 4 leaves the microswitch 6, the switch sends out a disconnection signal, and at the moment, the motor 10 rotates clockwise by 40 degrees to finish locking. At this point, the lock is closed.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
