The electronic control board 12 is mounted to the front panel 14, and similarly, the side of the front panel 14 facing the cabinet door is formed with a second cavity in which the electronic control board 12 is mounted, as shown in fig. 4. And, the above-mentioned electric drive assembly 13 is connected with the electronic control board 12 electricity, and this electric drive assembly 13 drives the spring bolt 11 along predetermineeing the direction (i.e. the direction perpendicular to the edge that is locked with the cabinet door on the cabinet door) reciprocating motion under the control of electronic control board 12 and realizes unblanking and locking. The structure of the lock tongue 11, the electronic control board 12, the electric driving assembly 13, the front shroud plate 14 and the rear lock plate 15 is similar to that of the existing electronic lock mounted on the locker, and will not be repeated here.

In this embodiment, the lock tongue 11 is provided with a toggle post 111 protruding toward the cabinet door, and the height of the toggle post 111 protruding from the lock tongue 11 can be adjusted as required. Correspondingly, the cabinet door lock also comprises a lock head 16 and a toggle piece 17.

The lock cylinder 16 includes a key hole 161 and a lever 162, wherein the lever 162 may be in a flat bar shape, and the lock cylinder 16 is fixed on the front panel 14 and is inserted into the first cavity of the rear lock plate 15 at a position where the front panel 14 is inserted with a key (i.e., the key hole 161 is exposed in the front panel 14), and the lever 162 is inserted into the first cavity of the rear lock plate 15 through a cabinet door (a through hole is formed in the cabinet door at a position corresponding to the lever 162). The lock head 16 can directly adopt the existing mechanical lock cylinder, and a mechanical key can be inserted into the key hole 161 and screwed to drive the shift lever 162 to rotate.

The driving piece 17 is in a long strip shape and is respectively in driving connection with the driving rod 162 and the driving post 111 on the lock tongue 11. The toggle piece 17 can be driven by the toggle lever 162 to rotate, and push the toggle post 111 and the lock tongue 11 to move along a preset direction to unlock.

In a normal state (i.e. the electric drive assembly 13 works normally), the toggle piece 17 is kept at a preset position and does not follow the movement of the lock tongue 11, i.e. when the lock tongue 11 is in an unlocking state, the toggle piece 17 is far away from the toggle post 111 on the lock tongue 11, and when the lock tongue 11 is in a locking state (when the end part of the lock tongue 11 protrudes out of the edge of the rear lock plate 15), the toggle piece 17 is adjacent to the toggle post 111 on the lock tongue 11, as shown in fig. 5 and 6. In an emergency state (for example, the electric driving assembly 13 is out of order and the lock tongue 11 is in a locked state), a mechanical key can be inserted into the key hole 161 of the lock head 16 and screwed, the shift lever 162 follows the mechanical key to rotate, thereby driving the shift plate 17 to rotate, and the shift plate 17 pushes the shift column 111 on the lock tongue 11 to move the lock tongue 11 along a preset direction (i.e., away from the edge of the cabinet door) until the lock tongue 11 is flush with the edge of the rear lock plate 15 or is retracted into the rear lock plate 15, so as to realize emergency unlocking, as shown in fig. 7.

The cabinet door lock is provided with the lock head 16 and the toggle piece 17 which are independent of the electric drive assembly 13, and the toggle rod 162 of the lock head 16 drives the toggle piece 17 to rotate so as to push the lock tongue 11 to unlock, so that the problem that the cabinet door lock cannot unlock under the condition that a circuit board breaks down or a battery is exhausted is avoided. Meanwhile, the poking piece 17 does not interfere the unlocking and locking processes of the electric driving assembly 13 for driving the lock head, namely the existence of the lock head 16 and the poking piece 17 does not affect the structure and energy consumption of the electric driving assembly 13.

In one embodiment of the present utility model, when the latch tongue 11 is in the locked state, the first end of the striking plate 17 contacts the side of the striking post 111 (the side facing the door frame of the cabinet door). In this way, when the lock tongue 11 is unlocked by the electric drive assembly 13, the toggle piece 17 does not affect the movement of the lock tongue 11, and when the lock tongue 11 moves from the unlocking state to the locking state, the toggle piece 17 does not obstruct the movement of the lock tongue 11. In practical application, a hook portion may be provided on a side of the toggle post 111 facing the door frame of the cabinet door, and the first end of the toggle piece 17 may be embedded into the hook portion, so that the toggle piece 17 may be prevented from slipping on the side portion of the toggle post 111.

In one embodiment of the present utility model, as shown in fig. 4, the electric driving assembly 13 includes a fixing bracket 132, a driving motor 134, and a driving circuit board 131, wherein the driving motor 134 and the driving circuit board 131 are respectively fixed to the rear locking plate 15 through the fixing bracket 132, for example, the driving motor 134 and the driving circuit board 131 are respectively fixed to the fixing bracket 132, and the fixing bracket 132 is further fixed to the second space of the rear locking plate 15. In practical applications, the driving circuit board 131 may have a battery thereon.

Accordingly, the second end of the toggle piece 17 is assembled to the fixing frame 132 through the toggle shaft 18, and the toggle lever 162 rotates by driving the toggle shaft 18 to rotate the toggle piece 17 around the second end thereof.

In one embodiment of the present utility model, the dial shaft 18 is cylindrical as a whole, and the outer periphery of the dial shaft 18 is stepped with a small diameter at both ends and a large diameter at the middle section.

Accordingly, the electric driving assembly 13 includes a fixing plate 133 in addition to the fixing frame 132, and the fixing plate 133 has a first shaft hole 1331 adapted to the diameter of the first end of the dial shaft 18, i.e., the diameter of the first end of the dial shaft 18 is slightly smaller than the diameter of the first shaft hole 1331, so that the dial shaft 18 can rotate relative to the fixing plate 133 when the first end of the dial shaft 18 is inserted into the first shaft hole 1331. The fixing bracket 132 has a second shaft hole 1321 adapted to the diameter of the second end of the moving shaft 18, that is, the diameter of the second end of the moving shaft 18 is slightly smaller than the diameter of the second shaft hole 1321, so that the moving shaft 18 can rotate relative to the fixing plate 133 when the second end of the moving shaft 18 is inserted into the second shaft hole 1321.

And, the diameters of the first shaft hole 1331 and the second shaft hole 1321 are required to be smaller than the diameter of the middle section of the toggle shaft 18. In particular, both ends of the outer circumference of the dial shaft 18 may have the same diameter, and accordingly, the first shaft hole 1331 and the second shaft hole 1321 also have the same diameter.

The fixing plate 133 is fixed to the fixing frame 132 in such a manner that the first shaft hole 1331 and the second shaft hole 1321 are coaxial, and the dial shaft 18 is fitted between the fixing plate 133 and the fixing frame 132 in such a manner that the first end is inserted into the first shaft hole 1331 and the second end is inserted into the second shaft hole 1321. In this way, the toggle shaft 18 can rotate relative to the fixed plate 133 and the fixed mount 132, while eliminating bearings.

The outer periphery of the intermediate section of the toggle shaft 18 has a non-right cylindrical shape, and may be, for example, a cylindrical shape with a flat surface, a regular hexagon, or the like. Correspondingly, the second end of the poking piece 17 is provided with a fixing hole 171 which is matched with the periphery of the middle section of the poking shaft 18, and the poking piece 17 is sleeved on the middle section of the poking shaft 18 through the fixing hole 171. That is, the toggle piece 17 is also installed between the fixing plate 133 and the fixing frame 132, and since the contact area between the toggle shaft 18 and the toggle piece 17 is not in a right cylinder shape, the relative slip of the toggle shaft 18 and the toggle piece 17 can be avoided, and the rotation of the toggle piece 17 is prevented from being affected.

In one embodiment of the present utility model, the fixing plate 133 is fixed to the fixing frame 132 at a side facing the cabinet door; the poking shaft 18 is provided with a jack, and an opening of the jack is positioned on the end face of the first end of the poking shaft 18. Thus, the lever 162 of the lock cylinder 16 can be directly inserted into the jack and drive the shift shaft 18 to rotate. The above-described manner can simplify the connection structure between the dial shaft 18 and the dial lever 162, avoiding jamming, since there is no intermediate transmission member.

The fixing frame 132 of the electric drive assembly 13 has a first opening 1322, and the size of the first opening 1322 in the preset direction (i.e. the sliding direction of the locking bolt 11) is larger than the size of the toggle post 111 in the preset direction, for example, the first opening 1322 may be rectangular. The toggle post 111 is inserted between the fixing frame 132 and the fixing plate 133 through the first opening 1322 so that the toggle post 111 can be in contact with the first end of the toggle piece 17 between the fixing frame 132 and the fixing plate 133. In this way, the fixing frame 132 does not obstruct the sliding of the toggle post 111 during the process that the toggle post 111 slides along the preset direction along with the lock tongue 11.

In one embodiment of the present utility model, the electrically driven component 13 further includes a reinforcement piece 135 connected to the locking bolt 11, and the reinforcement piece 135 is sleeved on the locking bolt 11 and slides along with the locking bolt 11 to enhance the structural strength of the locking bolt 11. The reinforcement piece 135 has a second opening 1351 adapted to the size of the toggle post 111; the toggle post 111 is inserted between the fixing frame 132 and the fixing plate 133 through the second opening 1351 and the first opening 1322.

In addition, the front shroud plate 14 may further be provided with a touch key module 141, and the touch key module 141 is electrically connected with the electronic control board 12. The touch key module 141 can convert the touch action input from the outside into an electrical signal, and the electronic control board 12 processes the electrical signal, for example, compares the electrical signal with a stored signal, and if the electrical signal passes the verification, the electronic control board 12 sends a control command to the electric driving component 13, so that the electric driving component 13 drives the lock tongue 11 to unlock. In practical applications, the touch key module 141 may be replaced by an image acquisition module, a fingerprint acquisition module, an iris acquisition module, etc., which are not described herein.

The utility model also provides a storage cabinet, which comprises a cabinet body, a cabinet door and the cabinet door lock, wherein the rear lock plate of the cabinet door lock is fixed on the inner side surface of the cabinet door, the front shroud plate is fixed on the outer side surface of the cabinet door, and the positions of the front shroud plate and the rear lock plate on the cabinet door are opposite.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model.
