Detailed Description

The following detailed description is provided in conjunction with the embodiments and with reference to the accompanying drawings in order to provide a further explanation of the technical features and advantages of the present invention.

As shown in fig. 1 to 13, the intelligent cabinet lock with a handle function of the present invention is used for a drawer and a cabinet, wherein a lock catch 12 is installed on the cabinet, a lock body 12 matched with the lock catch is installed in the drawer, and a handle 13 for pushing and pulling is installed outside the drawer, and comprises a lock catch, wherein the lock catch is a plate extending to a cavity of the drawer;

the lock body comprises a lock body upper cover 4 and a lock body lower cover 8, the lock body upper cover and the lock body lower cover are provided with a lock tongue 2, the lock body comprises a lock tongue and a rotation stopping mechanism, the lock tongue is rotatably arranged in a cavity of the sliding block seat, a torsion spring 1 for resetting is arranged between the lock tongue and the sliding block seat, the rotation stopping mechanism comprises an electromagnet, and a bolt of the electromagnet penetrates through a through hole of the sliding block seat and can be inserted into a limiting hole of the lock tongue;

Furthermore, the slider seat outwards extends out the member, and spring 6 is established to the cover on the member, and the spring is arranged in the cavity that lock body upper cover and lock body lower cover constitute, plays flexible effect that resets to the slider seat. The lock tongue is arranged in a cavity of the sliding block seat through a rotating shaft 3, and a rod piece on the sliding block seat is vertical to the rotating shaft.

Further, as shown in fig. 7-9, in the first embodiment, the electromagnet is a first electromagnet 5 installed in the same side direction of the rod, a plug pin is installed in a cavity of the first electromagnet, an elastic element (spring) is sleeved outside the plug pin, the slider seat is a first slider seat 7 with a through hole processed in the same side direction of the rod, and a limit hole matched with the plug pin is processed at the tail of the lock tongue. As shown in fig. 10-13, in the second embodiment, the electromagnet is a second electromagnet 9 installed in the vertical direction of the rod, a plug pin is installed in a cavity of the second electromagnet, an elastic element (spring) is sleeved outside the plug pin, the slider seat is a second slider seat 10 with a through hole formed in the vertical direction of the rod, and a limit hole matched with the plug pin is formed in the side portion of the latch bolt.

Furthermore, the sliding block seat, the spring and the electromagnet are all installed in a cavity formed by the lock body upper cover and the lock body lower cover, a groove matched with the lock tongue in a rotating mode is machined in the lock body upper cover, a step position is arranged on the lock body lower cover so that the sliding block seat can slide stably and linearly, and a hole corresponding to a rod piece on the sliding block seat is machined in the lock body lower cover. The electromagnet is also connected with a circuit board, the circuit board is connected with a battery or is connected with commercial power through a wire, and the commercial power is produced by household power consumption which is used after being subjected to voltage reduction and then is accessed through the wire. The circuit board and the battery are arranged in the cavity of the lock body or the cavity of the handle. The electronic module of the handle is a fingerprint head 131 and a password key 132, and the password key is arranged on the front surface of the handle. The fingerprint head is arranged on the front or the back of the handle. Specifically, a battery and a circuit board (not shown in the drawings) which are matched with the electromagnet are certainly provided, and a fingerprint module (fingerprint head), a bluetooth module, a touch screen module (digital key) or a card swiping module can be arranged on the circuit board and used for receiving an unlocking signal input from the outside and then controlling the electromagnet to be powered on or powered off so as to realize the unlocking and locking functions of the whole lock body. Electronic modules for receiving external lock-opening and lock-closing commands are currently mature in technology, but are not limited to the common components described above.

The working principle of the device of the invention is that firstly, the lock catch is designed as a plate for limiting the outward pulling of the lock tongue, the position of the slide block seat is designed, and the rod piece and the spring on the rod piece are combined, so that the whole slide block seat can automatically extend and retract and reset in the lock body, the lock of the lock tongue in a conventional mode is realized, namely, the drawer is pushed to move towards the cabinet by a handle, the lock tongue contacts with the lock catch and is linearly pressed down until the lock catch completely enters the lock catch and the lock tongue resets, the lock tongue is blocked by the lock catch, the locking state is not firm at the moment, the lock tongue can rotate, the lock tongue can be pressed by pressing the lock catch by pulling the handle outwards, the lock body can be reopened, and then the drawer is opened, the design of the torsion spring enables the lock tongue to quickly reset after the lock is unlocked by rotation, at the moment, the locking signal is transmitted to the, the outage of circuit board control electro-magnet for the inside bolt of electro-magnet stretches out forward under the effect of spring force, and the bolt runs through the through-hole on the sliding block seat after in getting into the spacing hole on the spring bolt, because spacing hole and the two dislocation set of pivot, the bolt hinders the rotation of pivot, and the sliding block seat also can not stretch out and draw back simultaneously, and the spring bolt is pinned completely, and the lock body is then totally locked, and the spring bolt is blocked by the hasp and can't rotate, and the unable pulling drawer of handle simultaneously. On the contrary, the unlocking action is carried out reversely, the circuit board controls the electrification of the electromagnet, the pin inside the electromagnet overcomes the acting force of the spring to retract under the electromagnetic acting force and returns from the limiting hole of the lock tongue, at the moment, the lock tongue can rotate around the rotating shaft and reset under the action of the torsion spring, and the lock body is pulled to realize unlocking. Conventional electronic components are made of existing technologies or materials, and can be directly purchased or ordered from the market by technicians according to required product models and specifications.
