Description

Technical Field

[0001] The invention relates to the technical field of locks, and in particular to a novel anti-stuck intelligent plane lock. Background Art

[0002] Flat locks are usually used on doors of distribution cabinets, transformers, etc. They are a kind of hidden door locks. Flat locks are generally composed of a lock body, a lock tongue, and a handle installed on the lock body and linked to the lock tongue. The lock tongue is also linked to a lock cylinder unlocking mechanism relative to the handle. Currently, there are electronic devices on the market that can be used to control the opening and closing of the lock tongue. However, this type of flat lock will have some problems after long-term use. For example, electronic devices will be fatigued and damaged or have other faults after long-term use, resulting in the door lock cannot be opened. At this time, the door lock can only be opened by a professional locksmith or even prying the lock, which not only wastes time but also easily damages the cabinet door. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a new type of anti-stuck intelligent flat lock with double insurance functions to avoid the lock tongue from getting stuck, in view of the deficiencies of the above-mentioned prior art.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a novel anti-stuck intelligent flat lock, comprising a lock body, a lock tongue and a handle installed in the lock body and linked with the lock tongue, the lock tongue is also linked with a lock core unlocking mechanism relative to the handle, characterized in that the handle comprises a hinged end movably hinged with the lock body and an unlocking end linked with the lock tongue and movable around the hinged end as a rotation point, a storage cavity for placing the handle is provided on the lock body, the storage cavity is provided with a through hole for the lock tongue to pass through at the position of the lock tongue, a first unlocking device is provided on the lock body on one side of the lock tongue, the first unlocking device comprises a first locking rod locked in linkage with the lock tongue, a keyhole through which the first locking rod can pass is provided on the lock tongue, the first locking rod is linked with a first electromagnet fixedly arranged on the lock body and capable of controlling the first locking rod to move back and forth in a straight line along the axial direction of the first locking rod, the first electromagnet is connected with an electronic component that can be intelligently controlled by using a mobile phone or other device, and a second unlocking device is provided on the lock body on the other side of the lock tongue relative to the first unlocking device.

[0005] By adopting the above technical solution, the handle is manually pressed, and the lock tongue is in the locked position after passing through the through hole. A locking signal is sent using a mobile phone or other device, and the first electromagnet receives the signal and pushes the first locking rod to lock the lock tongue to complete the locking action; when the lock needs to be opened, an unlocking signal is sent using a mobile phone or other device, and the first electromagnet receives the signal, and the first locking rod is pulled out of the lock tongue to complete the unlocking. If the first electromagnet and the components driving it fail to function due to long-term use, the first locking rod will continue to keep the lock tongue locked due to the spring inside the electromagnet. At this time, the second unlocking device can be activated to help unlock the door to avoid the door lock from getting stuck, making it convenient for people to use.

[0006] The above-mentioned new type of anti-stuck intelligent flat lock can be further configured as follows: the second unlocking device includes a second locking rod whose axis is on the same horizontal line as the axis of the first locking rod, the second locking rod is linked to a second electromagnet fixedly set on the lock body and capable of controlling the second locking rod to reciprocate along its axial straight line, the lock tongue is located at the keyhole and is provided with an opening at one end away from the handle through which the second locking rod can pass but not the first locking rod, and the outer diameter of the first locking rod is larger than the outer diameter of the second locking rod.

[0007] By adopting the above technical scheme, when the first electromagnet stops working and the first locking rod remains in the lock tongue locking state, the door lock cannot be opened at this time, then the second electromagnet can be started, and an unlocking signal can be sent through a mobile phone or other device. The second electromagnet receives the signal and drives the second locking rod to push the first locking rod along the axis. The first locking rod is pushed to the position of exiting the lock tongue and the lock eye, and the handle drives the lock tongue to exit the lock body. Since the opening on the lock tongue can pass through the second locking rod but not the first locking rod, interference between the lock tongue and the second locking rod can be avoided when unlocking, so that unlocking can be achieved. The second unlocking device plays a role of double protection. Even if the first unlocking device is damaged, it can still be unlocked. At the same time, it also has a certain warning effect on people and takes good maintenance measures.

[0008] The above-mentioned novel anti-jamming intelligent flat lock can be further configured as follows: the outer circumference of the lock tongue is in a semicircular arc shape, and the keyhole axis, the first lock rod axis and the second lock rod axis are on the same horizontal line.

[0009] By adopting the above technical solution, the lock tongue is set into a semicircle to avoid interference between the lock tongue and the lock body, and the keyhole axis, the first lock rod axis and the second lock rod axis are on the same horizontal line, in order to better realize the force transmission and help subsequent unlocking.

[0010] The above-mentioned new type of anti-stuck intelligent flat lock can be further configured as follows: the lock body is provided with a lock shell that can wrap the first unlocking device and the second unlocking device, and the lock body is provided with 4 installation stations evenly distributed around the first electromagnet and the second electromagnet, and the lock shell is provided with an installation platform relative to each installation station.

[0011] By adopting the above technical solution, the lock shell provides a better working environment for the first unlocking device and the second unlocking device, can avoid dust, and protect the components in the lock body. Among them, 4 installation stations can install electronic components with different shapes.

[0012] The novel anti-jamming intelligent flat lock can be further configured as follows: the lock body is provided with an internal hollow hinge column 14 corresponding to the hinged end of the handle, and a hinge sleeve movably hinged to the hinged end of the handle is fixedly provided inside the hinge column 14.

[0013] By adopting the above technical solution, the hinged sleeve can replace the friction between the handle and the lock body, and it is convenient to install and position the handle.
