Detailed Description

In order to better understand the present invention and make the structure and advantages thereof more prominent, the present invention will be described in detail with reference to the accompanying drawings 1-5 and the embodiments.

As shown in the attached drawings 1-2, the intelligent electronic lock for the chilled and fresh logistics cabinet comprises a shell 1 provided with a lock hole 13, and a lock tongue 2, a limiting rod 3, an electromagnet assembly 4, a trigger switch 5 and a driving assembly 6 are arranged in the shell 1. The spring bolt is die casting with the gag lever post, and is the metal die casting, can reduce the manufacturing cost of electronic lock, and stability is also stronger.

The gag lever post 3 is used for fixed spring bolt 2, and when the electronic lock needed the unblock, 3 anticlockwise rotations of drive gag lever post after 4 circular telegrams of electromagnet assembly, spring bolt 2 break away from the restriction of gag lever post 3, under the drive power of first reset block 21, clockwise rotation, 25 opening directions of locked groove are unanimous with lockhole 13 opening direction, and the set bar 01 can come out from lockhole 13. In this embodiment, the lock bolt 01 is not disposed on an electronic lock, the lock bolt is mounted on a door of the cabinet, and the electronic lock is mounted on the cabinet to lock and unlock the door of the cabinet, that is, to fix the lock bolt 01 by the lock slot 25. The perpendicular or crossing time of 25 opening directions of locked groove and 13 opening directions of lockhole triggers convex part 26 and presses trigger switch 5, and trigger switch 5 is closed, and the information transfer that is the lock state with spring bolt 2 gives the cold bright logistics cabinet control system who links to each other with the electronic lock, and cold bright logistics cabinet control system installs in the transport chamber or the place that people conveniently observed, can be at the outdoor cabinet door of the cold bright logistics cabinet of control of freezer and close. The control system of the cabinet is the prior art, and related descriptions can be found in the control system technology of the cabinet, so that detailed descriptions are not provided in the present specification.

As shown in fig. 3, the locking tongue 2 is provided with a first side arm 22, a second side arm 23, a rotating hole 24 and a first reset component 21 for facilitating rotation of the locking tongue 2, the locking tongue is slidably disposed on a side of the locking hole 13 and is provided with a locking groove 25, the locking groove 25 is located between the first side arm 22 and the second side arm 23, the second side arm 23 is provided with a locking protrusion 27, and a trigger protrusion 26 is disposed at a side end of the locking tongue 2 close to the second side arm 23. The locking groove 25 is used for fixing the bolt 01, the first side arm 22 and the second side arm 23 are used for facilitating the locking groove 25 to fix the bolt 01, and the locking protrusion 27 is used for facilitating the limiting rod 3 to fix the bolt 2. The trigger convex part 26 is arranged at the side end of the bolt 2 close to the second side arm 23, when the bolt fixes the lock bolt, the trigger convex part can press the trigger switch 5, the trigger switch 5 is closed, and the information that the electronic lock is locked is transmitted to the control system of the chilled and fresh logistics cabinet. The chilled logistics cabinet control system can be provided with a prompting lamp connected with the trigger switch, and when the electronic lock is in a locking state, the prompting lamp is turned on. When the electronic lock is in a locking state, an indicator lamp of the control system of the chilled logistics cabinet is on, so that the cabinet door is in a closing state. If the electronic lock is designed to: when the electronic lock is in an unlocking state, the trigger convex part presses the trigger switch, and the prompt lamp is turned on; when the electronic lock is in a locked state, the trigger switch is not pressed by the trigger convex part, and the prompt lamp of the chilled goods logistics cabinet control system is not on. The reason why the prompt lamp of the chilled and fresh logistics cabinet control system is not on may be that the damage of the circuit causes the circuit to be open circuit or short circuit, and at this time, the cabinet door of the chilled and fresh logistics cabinet is in an open state, and people cannot monitor the cabinet door.

As shown in fig. 4, in order to fix the bolt 2 by the limiting rod 3, a limiting convex part 33 matched with the locking convex part 27 is arranged at one end of the limiting rod 3. The other end of the limiting rod 3 is connected with the electromagnet assembly 4, and the electromagnet assembly 4 drives the limiting rod 3 to rotate anticlockwise, so that the fixing of the limiting rod 3 on the lock tongue 2 is released. The limiting rod 3 is provided with a sliding hole 32 and a second reset part 31 which are convenient for the limiting rod to rotate, and under the condition that the electromagnet assembly 4 is not electrified, the limiting rod 3 loses the driving force of the electromagnet assembly 4 and can rotate clockwise under the driving of the second reset part 31.

The gag lever post 3 and trigger switch 5 divide and locate the both ends of spring bolt 2, and gag lever post 3 is located the one end that is close to second lateral wall 23, and trigger switch 5 is located the one end that is close to trigger convex part 26.

Referring again to fig. 3, in order to facilitate the smooth entry of the latch 01 into the latching groove 25 to be fixed, the length of the second side arm 23 is greater than that of the first side arm 22.

As shown in fig. 5, the driving assembly 6 includes a first driving rod 61 and a driving spring 62 sleeved on the first driving rod 61, and the driving spring 62 is disposed in the housing 1. When the electronic lock is unlocked, the driving spring 62 of the driving assembly 6 generates an elastic force to drive the first driving rod 61, and the first driving rod drives the cabinet door connected with the electronic lock to open. Further, the first drive lever is provided with a positioning portion 63 for positioning the drive spring 62, and the positioning portion 63 abuts against the inside of the housing 1.

Accordingly, the housing 1 is provided with a mounting portion 16 for mounting the driving assembly, and the mounting portion 16 is opened with a through hole (not shown).

Referring to fig. 1-2 again, the housing is provided with an unlocking window 02 for manually unlocking the electronic lock. The utility model discloses the electronic lock is used for cold bright commodity circulation cabinet, and the temperature setting in the cold bright commodity circulation cabinet is decided according to its inside cold bright food, if cold bright food needs lower temperature, this temperature probably causes even to freeze in the cold bright commodity circulation cabinet, can freeze the inside of electronic lock even. When the temperature in the cold bright commodity circulation cabinet is too low, cause the inside freezing of electronic lock, the control system of cold bright commodity circulation cabinet can't carry out artifical unblock through the unblock window when 4 circular telegrams unblock electronic locks to electromagnet assembly, prevents that the electronic lock from dying, and the cabinet door of cold bright commodity circulation cabinet can't be opened to the outside.

The unlocking window 02 is arranged at one end of the limiting rod 3 departing from the limiting convex part 33 and one end of the electromagnet assembly 4 connected with the limiting rod 3. When the electronic lock is frozen, the electromagnet assembly 4 is electrified to unlock the electronic lock, and the limiting rod 3 can be pulled to rotate anticlockwise through the unlocking window 02, so that the electronic lock can be unlocked.

As shown in fig. 6, the housing 1 includes a front housing 11 and a rear housing 12, a receiving cavity (not shown) is formed in the front housing 11 and the rear housing 12 after the front housing 11 and the rear housing 12 are covered, and the front housing 11 is provided with a positioning post 14 for positioning a limiting rod and a locking tongue, and a supporting post 15 for supporting a first reset component, and the positioning post 15 is provided with a screw hole (not shown).
