The storage cabinet of the embodiment of the invention is provided with an emergency unlocking mechanism 300 for unlocking the electromagnetic lock 200 and unlocking the storage compartment 100 under special conditions. The emergency unlocking mechanism 300 includes a switch assembly 301, the switch assembly 301 being used to operate and control the opening of the electromagnetic lock 200, the switch assembly 301 operating the lever 3, and a plurality of wire rods 2. Wire rod 2 and the electromagnetic lock 200 one-to-one of matter storage lattice 100, and every wire rod 2 is connected with the driving lever of an electromagnetic lock 200, and the motion of wire rod 2 can drive the driving lever motion and open electromagnetic lock 200, can control opening of the corresponding electromagnetic lock 200 through the motion of control wire rod 2.

Referring to fig. 4, the operating rod 3 is connected to any one of the wire guide rods 2 through the first connecting structure 4, and the portion of the first connecting structure 4 connected to the wire guide rods 2 can be switched between all the wire guide rods 2; when the operation rod 3 moves along the first direction, the operation rod 3 drives the wire rod 2 connected with the operation rod to move through the first connecting structure 4, and the corresponding electromagnetic lock 200 is opened. The first connecting structure 4 can only connect the operating rod 3 and one wire guide rod 2 of the plurality of wire guide rods 2 at the same time, open the corresponding electromagnetic lock 200 and control the opening of a single storage lattice 100; the part of the first connecting mechanism 4 connected with the wire rods 2 can be switched between all the wire rods 2, and the operating rod 3 can be connected with any one of the wire rods 2 in all the wire rods 2 as required to open the corresponding electromagnetic lock 200, so that the purpose of accurately opening a single storage lattice 100 is achieved. Compared with the prior art, the opening of all the storage compartments 100 is controlled by the lifting rod; according to the storage cabinet disclosed by the embodiment of the invention, the opening of a single storage lattice 100 is controlled through the first connecting structure 4, and any storage lattice 100 can be accurately controlled to be opened; when only need open a matter storage lattice 100 and access article, opened other matter storage lattices 100 simultaneously, the problem that article were lost in other matter storage lattices 100 that causes is avoided, promotes the security of locker.

In the storage cabinet of the embodiment of the invention, as shown in fig. 4, 6 and 7, the operation rod 3 is connected with all the wire rods 2 through the second connecting structure 5, and when the operation rod 3 moves along the second direction, the operation rod 3 drives all the wire rods 2 to move through the second connecting structure 5, so that all the electromagnetic locks 200 are unlocked.

Referring to fig. 1, 4 and 5, the first connecting structure 4 includes a lever 41 for connecting the operating lever 3 and the wire guide lever 2, a first end 411 of the lever 41 being connected with the operating lever 3, and a second end 412 of the lever 41 being connected with the wire guide lever 2. The first connecting structure 4 of the embodiment of the invention adopts the lever 41 for connection, wherein the distance between the operating rod 3 and the fulcrum of the lever 41 is greater than the distance between the wire guide rod 2 and the fulcrum of the lever 41, so that the force applied when the operating rod 3 is operated to open the electromagnetic lock 200 can be reduced, and the operation is convenient. When the wire rod 2 drives the shift lever to determine a unique movement direction when the electromagnetic lock 200 is unlocked, if the operating rod 3 drives the wire rod 2 to move along the same direction along two different movement directions through two different connection structures (the first connection structure 4 and the second connection structure 5), a steering structure needs to be disposed in any one of the first connection structure 4 or the second connection structure 5. The first connecting structure 4 of the embodiment of the present invention is connected using the lever 41, the movement of the operating rod 3 in the first direction is the movement of the operating rod 3 in a certain direction along the axis thereof, which is the axis along the extending direction of the operating rod 3, when the operating rod 3 moves in the first direction, the operating rod 3 rotates the lever 41, the portion between the operating rod 3 and the fulcrum of the lever 41 moves in the first direction, the portion between the wire rod 2 and the fulcrum of the lever 41 moves in the direction opposite to the first direction, and drives the wire rod 2 to move in the direction opposite to the first direction, so that the electromagnetic lock 200 is opened. The first direction of the storage cabinet of the embodiment of the present invention is the direction indicated by the arrow a1 in fig. 4, i.e., the movement of the operating lever 3 from the top to the bottom along the axis of the extending direction thereof. When a single electromagnetic lock 200 is unlocked, the operating rod 3 is pressed downwards to enable the operating rod 3 to move along the first direction, so that a corresponding electromagnetic lock 200 is opened, and then a corresponding storage compartment 100 is opened.

It should be noted that the movement of the operating lever 3 along its axis includes a movement in a direction approaching the housing 1 along the axis and a movement in a direction away from the housing 1 along the axis. The storage cabinet of the embodiment of the invention, as shown in fig. 4, has a first direction of movement along the axis toward the housing 1. However, the first direction may also be a movement along the axis in a direction away from the housing 1, and the connection manner and movement process of the switch assembly are similar to those of the above-mentioned embodiments, and are not described again.

In order to allow the lever 41 to be switched between a plurality of wire guide bars 2, the lever 41 is configured to connect the operating rod 3 to different wire guide bars 2 as needed. The second end 412 of the lever 41 cannot be fixedly connected to the guide bar 2, so that the second end 412 of the lever 41 can be switched between a plurality of conductor bars 2. The wire guide bar 2 is provided with a first protrusion 21 which is engaged with the second end 412 of the lever 41, and the second end 412 of the lever 41 is located behind the first protrusion 21 in the first direction, that is, as shown in fig. 4, 5 and 6, the second end 412 of the lever 41 is located below the first protrusion 21. When the operating lever 3 is moved in the first direction, the second end 412 of the lever 41 is moved from below to above and is brought into abutting contact with the first projection 21, pushing the wire guide rod 2 to move in the direction from below to above, i.e., pushing the wire guide rod 2 to move in the direction opposite to the first direction. When the operation lever 3 is located at the initial position and the operation lever 3 is moved in the third direction, the second end 412 of the lever 41 may be displaced behind the first protrusions 21 of all the wire guides 2. When the operating rod 3 is located at the initial position, the second end 412 of the lever 41 is located behind all the first protrusions 21, and when the operating rod 3 moves along the third direction, the operating rod 3 can drive the lever 41 to move along the third direction, so that the second end 412 of the lever 41 can be transferred to any other first protrusion 21 of the wire guide rod 2 from behind the first protrusion 21 of one of the guide rods 2, and then the lever 41 is connected with the operating rod 3 and any one wire guide rod 2 as required, so that the specified storage lattice 100 can be accurately controlled to be opened.

In the present application, all expressions indicating relative positional relationships such as "forward" and "rearward" in a certain direction refer to positions close to a starting point in the direction of an arrow in the corresponding drawings; "rearward" refers to a location proximate to where the arrow points. For example, as shown in fig. 4, the first direction is a direction from top to bottom indicated by an arrow a1, and the "second end 412 of the lever 41 is located behind the first protrusion 21" means that the second end 412 of the lever 41 is located below the first protrusion 21. "initial position" means: the relative position of the lever 3 in the first direction when the lever 3 is not moved in the first direction to open a single storage compartment 100 nor moved in the second direction to open all storage compartments 100. At this time, the operating lever 3 remains relatively stationary in the first and second directions, but can be moved in the third direction so that the first connecting structure 4, i.e., the lever 41 of the embodiment of the present invention, can be arbitrarily switched between all the wire rods 2. The storage cabinet of the embodiment of the invention has all the initial positions except for other indications, which are the positions described above.

The third direction is a moving direction of the second end 412 of the lever 41 when switching between the plurality of wire guides 2, and the third direction is related to a positional relationship of the plurality of wire guides 2 with respect to the operation lever 3. In the storage cabinet of the embodiment of the invention, as shown in fig. 4 and 6, the extending direction of the wire guide rod 2 is parallel to the extending direction of the operating rod 3, and the moving direction of the wire guide rod 2 for opening the electromagnetic lock 200 is parallel to the axis of the extending direction of the wire guide rod 2. The plurality of wire guide rods 2 are uniformly arranged on the same circumference, the center of the circle is positioned on the axis of the extension direction of the operating rod 3, and the distances from all the first bulges 21 to the axis are the same; when the operating lever 3 is in the initial position, the first protrusions 21 of all the wire guide bars 2 are located in the same plane. The second end 412 of the lever 41 does not collide with the first protrusion 21 during the movement in the third direction, and does not affect the switching of the lever 41 between the plurality of wire guides 2. According to the storage cabinet disclosed by the embodiment of the invention, the movement of the operating rod 3 in the third direction is the rotation of the operating rod 3 around the axis of the extending direction of the operating rod 3, and the lever 4 is kept static relative to the operating rod 3, so that the lever 41 can be driven to synchronously rotate around the axis in the rotating process of the operating rod 3 around the axis of the extending direction. When the lever 41 is switched between the plurality of wire guides 2, the second end 412 of the lever 41 may be always located behind the first protrusion 21 of the wire guide 2 in the first direction. During the rotation of the lever 41, the second end 412 of the lever 41 may pass behind the first protrusion 21 of any one of the wire guide bars 2 and stay behind the first protrusion 21 of any one of the wire guide bars 2 as required; and then the operating rod 3 moves along the first direction to drive the wire guide rod 2 corresponding to the first protrusion 21 located in front of the second end 412 of the lever 41 to move, so as to open the electromagnetic lock 200 corresponding to the wire guide rod 2.

It should be noted that the wire guides 2 may also be arranged on the housing 1 in other ways with respect to the operating lever 3, and correspondingly, the movement of the operating lever 3 in the third direction is adapted to the arrangement of the wire guides 2. For example, when all the wire guides 2 are arranged at intervals along a straight line, the operation lever 3 is located on one side of the straight line, and the movement of the operation lever 3 in the third direction is the movement of the operation lever 3 along a straight line parallel to the straight line. The movement of the operating rod 3 in the third direction may be a clockwise rotation about an axis in the direction of extension thereof, or a counterclockwise rotation about said axis.

Referring to fig. 4, 6 and 7, the operating rod 3 is provided with a slot 31 corresponding to the first end 411 of the lever 41, the slot 31 extends in a direction perpendicular to the first direction, and the first end 411 of the lever 41 is inserted into the slot 31. When the operating rod 3 moves along the first direction, the operating rod 3 can generate a pushing force along the first direction on the lever 41, and the lever 41 rotates around the fulcrum under the action of the force; when the operating rod 3 moves along the third direction, the operating rod 3 can generate a pushing force along the third direction on the lever 41 through the slot 31, and the lever rotates around the axis of the extending direction of the operating rod 3 under the action of the pushing force. After the lever 41 is connected to the operating rod 3, the operating rod 3 transmits a force along the first direction and transmits a force along the third direction to the lever; compared with other connection modes, such as hinging, the lever 41 is inserted into the operating rod 3 through the slot 31, so that the structure is simple, and the processing and the installation are convenient.

The portion of the lever 41 inserted into the slot 31 includes two side surfaces perpendicular to the first direction, and when the lever is in the initial position, one of the two side surfaces is in contact with the slot and the other side surface has a gap with the slot, as shown in fig. 4 and 7. And the side in contact with the slot 31 is a first side 413 and the other side is a second side 414. The side wall of the slot 31 opposite to the first side 413 is the first side wall 311, and the side wall of the slot 31 opposite to the second side 414 is the second side wall 312. Along the first direction, the length of the gap is larger than or equal to the movement distance of the operating rod when the operating rod moves along the second direction to unlock all the electromagnetic locks. That is, when the operating rod 3 is located at the initial position, the first side 413 contacts the first side 311, and at this time, if the operating rod 3 moves along the first direction, the operating rod 3 can drive the lever 41 to move and drive the corresponding wire guiding rod 2 to move, so as to open the corresponding electromagnetic lock 200. There is a gap between the second side 414 and the second side wall 312, and the distance between the second side 414 and the second side wall 312 is greater than the moving distance of the operation lever 3 when the operation lever 3 moves in the second direction. So that when the operating lever 3 is moved in the second direction from the initial position to unlock all the electromagnetic locks 200, the operating lever 3 does not move the lever 41.

Referring to fig. 4 and 7, the second connecting structure 5 includes a connecting plate 51 for connecting the operation rod 3 and all the wire rods 2, and when the operation rod 3 moves in the second direction, all the wire rods 2 are moved by the connecting plate 51 and all the electromagnetic locks 200 are opened. The movement of the operating lever 3 in the second direction is a movement of the operating lever 3 in the direction opposite to the first direction along its axis, i.e., the direction indicated by the arrow a2 in fig. 7: in a direction from below to above along the axis of the operating rod 3. When all the electromagnetic locks 200 need to be unlocked, the operating rod 3 is pulled upwards to move the operating rod 3 along the second direction, and all the electromagnetic locks 200 are unlocked, so that all the storage compartments 100 are unlocked. When the operating rod 3 moves along the first direction, the connecting plate 51 keeps static, so that the situation that all the electromagnetic locks 200 are unlocked when the operating rod 3 moves along the first direction can be avoided, and the safety of the storage cabinet is further improved.

It should be noted that the first direction and the second direction in the embodiment of the present invention are two opposite directions along the axis of the operation rod 3, when the wire guiding rod 2 moves along the second direction, the wire guiding rod 2 can drive the shift lever on the electromagnetic lock 200 to move so as to open the corresponding electromagnetic lock 200, the operation rod 3 converts the movement of the operation rod 3 along the first direction into the movement of the wire guiding rod 2 along the second direction through the lever 41, and the opening of the single electromagnetic lock 200 is precisely controlled.

The connecting plate 51 is provided with a connecting hole matched with the operating rod 3 at a position corresponding to the operating rod 3, and the connecting plate 51 is sleeved on the outer side of the operating rod 3 through the connecting hole. The second connecting structure 5 further includes a blocking portion 52 located on the operating rod 3 and abutted to the connecting plate 51, as shown in fig. 4 and 7, the blocking portion 52 includes an annular snap spring sleeved on the outside of the operating rod 3, and along the second direction, the annular snap spring is located in front of the connecting plate 51, so that when the operating rod 3 moves along the second direction, the annular snap spring can abut to the connecting plate 51 and drive the connecting plate 51 to move along the second direction. The blocking portion 52 further comprises a limiting groove for fixedly mounting the annular clamp spring, the annular clamp spring is located in the limiting groove, and when the annular clamp spring drives the connecting plate 51 to move, sliding relative to the operating rod 3 along the second direction is prevented. Moreover, in order to prevent the ring-shaped clamp spring from directly penetrating through the middle of the connecting hole, the plane of the ring-shaped clamp spring is parallel to the plane of the connecting hole 51, and the cross-sectional area of the ring-shaped clamp spring on the plane is larger than that of the connecting hole. As shown in fig. 6 and 7, the extending direction of the wire rod 2 is perpendicular to the plane of the connecting plate 51, a position of the connecting plate 51 corresponding to the wire rod 2 is provided with a limiting hole 511 matched with the wire rod 2, one end of the wire rod 2 close to the connecting plate 51 passes through the limiting hole 511, the wire rod 2 is provided with a limiting protrusion 22 matched with the limiting hole 511, the limiting hole 511 is located in front of the limiting protrusion 22 along the second direction, and the cross-sectional area of the limiting hole 511 is smaller than the cross-sectional area of the limiting protrusion 22. So that when the connecting plate 51 moves along the second direction, the connecting plate 51 can abut against the wire guide rod 2 to drive the wire guide rod 2 to move along the second direction. The cross section of the limiting protrusion 22 is a section of the limiting protrusion 22 parallel to the plane of the limiting hole 511.

Referring to fig. 4 and 7, the switch assembly 301 further includes a housing 1, and a sleeve 6 disposed outside the operating rod 3, wherein the connecting plate 51 is disposed outside the sleeve 6, and one end of the sleeve 6 is provided with a flange 61 engaged with the connecting plate 51. When the operating rod 3 moves in the second direction, the flange 61 abuts against the connecting plate 51, and the connecting plate 51 is driven to move in the second direction. When the operating rod 3 moves along the first direction, one end of the sleeve 6 abuts against the shell 1, the sleeve 6 keeps static relative to the shell 1, the connecting plate 51 keeps static relative to the shell 1, and when the operating rod 3 is prevented from moving along the first direction, the connecting plate 51 is driven to open all the storage lattices 100, so that the use safety of the storage cabinet is improved.

It should be noted that, when the switch assembly 301 is provided with the sleeve 6, in the process of moving the operating rod 3 along the second direction, the blocking portion 52 abuts against the front end of the sleeve 6 along the second direction, and drives the sleeve 6 to move along the second direction, the flange 61 of the sleeve 6 abuts against the edge of the connection hole of the connection plate 51, the flange 61 of the sleeve 6 drives the connection plate 51 to move along the second direction, the limiting hole 511 on the connection plate 51 abuts against the limiting protrusion 22 on the lead bar 2, and drives the lead bar 2 to move along the second direction, and all the electromagnetic locks 200 are opened. At this time, the distance between the second side 414 and the second sidewall 312 is greater than the distance between the blocking portion 52 and the connection plate 51.
