Detailed Description

The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments described in the present disclosure, all other embodiments obtained by a person skilled in the art without creative efforts are within the scope of the present disclosure.

An embodiment of the utility model provides an electronic lock with separation and reunion function, simple structure, low in manufacturing cost, operational reliability are strong, are being applied to the electronic lock, can produce good theftproof ability to when violence is opened, can enough guarantee that the lock can not be opened, also can protect inside spare part.

As shown in fig. 1 to 4, an electronic lock with a clutch function includes a rotating shaft 2, a clutch dial 3 and a bracket 1, wherein the bracket 1 is provided with a mounting hole 11, the lower part of the clutch dial 3 is rotatably disposed in the mounting hole 11, the edge of the upper part of the clutch dial 3 is limited by the side edge of the mounting hole 11, the rotating shaft 2 is inserted into an inner hole 311 in the center of the clutch dial 3, the bottom of the rotating shaft 2 is provided with a dial 21, the dial 21 is provided with a lower latch 22, the bottom of the clutch dial 3 is provided with an upper latch 31, and the lower latch 22 is engaged with the upper latch 31 to form a torque transmission mechanism; a spring mounting part 35 is arranged outside the clutch turntable 3, a spring 4 is sleeved outside the spring mounting part 35, the top of the rotating shaft 2 is fixedly connected with a pressing plate 6, and the pressing plate 6 is pressed on the spring 4; one end of the spring 4 is pressed on the clutch turntable 3 to press the clutch turntable downwards, and the other end of the spring is pressed below the pressing plate 6 to drive the rotating shaft 2 to move upwards.

The spring mounting portion 35 is an annular portion located on the side of the inner hole 311. The spring mounting part can also be a column body, and the spring 4 is sleeved outside the column body.

The top of the rotating shaft 2 is connected with a bolt 7, and the bolt 7 presses the pressing plate 6 on the top of the rotating shaft 2 by utilizing threads.

The top of the rotating shaft 2 is provided with a clamp spring groove, a clamp spring is clamped in the clamp spring groove, and the clamp spring presses the pressing plate 6 on the top of the rotating shaft 2.

The turntable 21 is limited by the side edge of the mounting hole 11 and moves upwards against the side edge of the mounting hole 11 under the action of the spring 4.

The bottom of the rotary disc 21 is provided with a non-circular special-shaped hole, and a rotating rod matched with the special-shaped hole in shape can be inserted into the special-shaped hole, so that the rotary disc 21 is driven to rotate by the rotating rod. The bottom of the mounting disc of the device is provided with a special-shaped hole, so that the turntable 21 can be conveniently rotated in an unlocking state, and the lock can be unlocked reversely and positively. Therefore, the shape is not limited to be strange as long as it is not a circular hole. For example, triangular holes are adopted, or the holes are quadrangular or pentagonal, or irregular. Moreover, elliptical holes with larger ratio of major axis to minor axis can be used. At present, in order to facilitate processing and reduce cost as much as possible, enterprises adopt a round hole to be processed, and then one or two notches are processed on the basis, so that a special-shaped hole meeting requirements is formed. The rotating rod with the same shape is inserted into the special-shaped hole, so that the rotating disc 21 can be driven to rotate, and the rotating shaft 2 is driven to rotate.

The clutch turntable 3 is provided with a movable stop block 32, the bracket 1 is provided with a first limit stop block 12 and a second limit stop block 13 which limit the movement amount of the movable stop block 32, and when the movable stop block 32 abuts against the second limit stop block 13, a motor locking rod is inserted into the locking opening 34 so as to lock the clutch turntable 3.

A first torsion spring connecting end 14 is arranged on the bracket 1, a second torsion spring connecting end 33 is arranged on the clutch turntable 3, and a torsion spring is arranged between the first torsion spring connecting end 14 and the second torsion spring connecting end 33; the first torsion spring connecting end 14 and the second torsion spring connecting end 33 are not located on the same radius from the axle center of the clutch turntable 3; the bottom of the clutch turntable 3 is provided with a torsion spring groove 331, and when the torsion spring contracts, the torsion spring can enter the torsion spring groove 331; when clutch disc 3 rotates to before the critical position, the torsional spring hinders clutch disc 3's rotation, works as clutch disc 3 passes the critical position after, the torsional spring promotes clutch disc 3 rotates. When the critical position is not exceeded, if the lock is not unlocked at the moment, the external force is cancelled, and the clutch turntable 3 is worth recovering to the original position under the action of the torsion spring. When the critical position is exceeded, which means that the unlocking is needed, the torsion spring provides assistance to push the clutch turntable 3 to rotate to the unlocking position. Therefore, the lock using the device has the advantages of easy control of force, good feedback effect and good unlocking hand feeling.

For better results, the lower latch 22 of the present device, which cooperates with the engaging surface of the upper latch 31, may be generally configured as an inclined surface, and in special cases may be configured as an arc surface or other type of surface. If a vertical surface is used, the effect is reduced unless assistance from other mechanisms is obtained. Therefore, for cost reasons, in a normal case, the inclined surfaces are provided.

The device works in an unlocking state and a locking state. The electromagnetic device retracts into the locking rod to enable the locking rod and the locking port 34 to be separated from each other, and the locking rod is in an unlocking state; the electromagnetic device is in a locked state when it extends out of the locking lever and is inserted into the locking opening 34.

The unlocking state works: at this point, the locking lever is not inserted into the locking opening 34, so that the clutch disk 3 can be rotated between a defined amount of rotation between the first limit stop 12 and the second limit stop 13. At this time, the clutch dial 3 and the dial 21 are connected together by the spring, and therefore, rotate together to complete the unlocking operation.

And (3) working in a locking state: at this time, the clutch disk 3 cannot rotate due to the second limit stopper 13 and the lock lever. And when the clutch turntable is violently opened, the rotating rod is required to be inserted into the special-shaped hole, and the clutch turntable 3 is intentionally driven to work to complete unlocking by rotating the turntable 21. The device is provided with a clutch device, the rotating force acted on the rotating disc 21 is large enough, so that the inclined plane where the lower latch 22 and the upper latch 31 are meshed slides relatively, namely the elastic force of a spring is overcome, the clutch rotating disc 3 and the rotating disc 21 are separated from each other, and the meshing action of the lower latch 22 and the upper latch 31 is invalid. The rotary disk 21 is finally allowed to rotate relative to the clutch disk 3, which means that even if the rotary disk 21 is rotated by force, the clutch disk 3 and the rotary disk 21 are separated from each other and cannot rotate, i.e. cannot be unlocked.

When the rotary disc 21 and the clutch rotary disc 3 rotate relatively, the parts in the clutch device are not damaged, and the locking operation can be continuously executed in the follow-up process.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive. The scope of the invention is indicated by the appended claims, rather than the foregoing description, and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
