[0006] In some embodiments, the bracket further includes: a first slide rail formed on the body and extending in a third direction; and a first stepped screw disposed within the first slide rail and coupled to a locking plate such that the locking plate approaches or moves away from the fixing hole in a third direction.

[0007] In some embodiments, the drive plate includes: a second slide rail including an unlocking end and a locking end, wherein the distance between the unlocking end and the fixing part exceeds the distance between the locking end and the fixing part; and a first stepped screw is disposed in the second slide rail and is adapted to move from the locking end to the unlocking end of the second slide rail during the sliding of the drive plate from the locked position to the unlocking position.

[0008] In some embodiments, the device further includes a spring disposed between the drive plate and the bracket, with one end of the spring coupled to the drive plate and the other end coupled to the bracket.

[0009] In some embodiments, the drive plate further includes a mounting post extending in a first direction and at least partially passing through the spring.

[0010] In some embodiments, the support further includes: at least one third sliding hole formed on the body and arranged such that its axis is parallel to a third direction, the at least one third sliding hole being adapted to at least partially accommodate the baffle plate sliding along the third direction.

[0024] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure.

The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment".

[0027] As briefly mentioned earlier, in traditional technology, some drawer units in chests of drawers move in and out of the cabinet frame via a rocker arm mechanism. Specifically, the rocker arm mechanism includes a spiral groove cam arranged inside the drawer and a drive component coupled to the cabinet frame. The drive component has a drive groove on the side facing the spiral groove cam, which threadedly engages with the spiral groove of the cam. Thus, during the rotation of the spiral groove cam, the interaction between the drive component and the spiral groove cam allows the drawer unit to move in and out relative to the cabinet frame. To ensure electrical safety, the drawer (i.e., the drawer unit) of the chest of drawers must be interlocked with the fixed support; that is, the rocker arm mechanism cannot drive the drawer out of the fixed frame while the drawer is locked to the fixed support. Traditional chests of drawers use a sliding plate interlocking structure, which is cumbersome to unlock.

[0028] The interlocking device for a drawer cabinet and the drawer cabinet provided in this disclosure solve, or at least partially solve, the aforementioned problems and other potential problems existing in conventional solutions. According to some embodiments of the interlocking device for a drawer cabinet according to this disclosure, its drive plate is linked to a locking plate and a blocking plate, respectively, and the drive plate can slide between a locked position and an unlocked position under user operation. When the drive plate is in the locked position, the locking plate is inserted into the fixing hole of the fixing part. Furthermore, the blocking plate at least partially obstructs the handle insertion hole of the rocker arm mechanism, thereby restricting the insertion of the rotating handle of the rocker arm mechanism into the handle insertion hole, and thus restricting the operation of the rocker arm mechanism. In this way, the interlocking device achieves interlocking of the rocker arm mechanism during the locking of the drawer and the fixing part, thereby improving the electrical safety of the drawer cabinet.

[0029] If the user presses the drive plate, it slides from the locked position to the unlocked position. Through the linkage between the drive plate and the locking plate, the drive plate can disengage the locking plate from the fixing hole of the drawer cabinet's fixing part. Furthermore, through the linkage between the drive plate and the blocking plate, the drive plate can also push the blocking plate to slide in a third direction, thereby exposing the handle insertion hole of the rocker arm mechanism on the drawer. This allows the rocker arm mechanism's rotating handle to be inserted into the handle insertion hole, activating the rocker arm mechanism and causing the drawer to disengage from the drawer cabinet's fixing part. Thus, the interlocking device can be quickly and easily disengaged by the user, facilitating maintenance and installation of the drawer cabinet.

[0030] Figure 1 A partial structural schematic diagram of a drawer chest according to some embodiments of the present disclosure is shown. For example... Figure 1 As shown, the drawer cabinet generally includes a cabinet frame, at least one fixing part 6 coupled to the cabinet frame, and at least one drawer 7 coupled to the fixing part 6. In some embodiments, the drawer cabinet may include multiple fixing parts 6, which are arranged in the cabinet frame along the direction of gravity, and a predetermined interval is left between two adjacent fixing parts 6. Multiple drawers 7 may be arranged in the interval between two adjacent fixing parts 6.

[0031] In some embodiments, the drawer 7 can slide along a predetermined direction (e.g., the depth direction of the drawer cabinet perpendicular to the user's side) on the fixing part 6 to enter or leave a predetermined position (e.g., a working position, a detection position, or a disconnected position). In some embodiments, a slide rail can also be arranged on the side of the fixing part 6 facing the drawer 7, extending along the depth direction. Correspondingly, a groove 62 that mates with the slide rail is provided on the side of the drawer 7 facing the fixing part 6. Through the interaction of the slide rail and the groove 62, the drawer 7 can slide more stably relative to the fixing part 6 along the depth direction. In some embodiments, the user can control the drawer 7 to slide along the depth direction to move closer to or further away from the user.

[0032] Figure 2 A schematic diagram of the interior of drawer 7 according to some embodiments of the present disclosure is shown. Figure 3 A schematic diagram of the fixing part 6 of a drawer cabinet according to some embodiments of the present disclosure is shown. For example... Figure 2 and Figure 3As shown, the drawer cabinet also includes a rocker arm mechanism, which is arranged between the drawer 7 and the fixed part 6 and adapted to drive the drawer 7 to slide relative to the fixed part 6, thereby enabling the drawer 7 to enter and exit the cabinet frame. In some embodiments, the rocker arm mechanism includes a spiral groove cam 81 arranged in the drawer 7 and a drive member 82 arranged in the fixed part 6. The spiral groove cam 81 is rotatably coupled to the bottom surface of the drawer 7 near the fixed part 6, and a portion of the circumferential surface of the spiral groove facing the fixed part 6 protrudes from the bottom surface of the drawer 7 and engages with the drive groove of the drive member 82. In this way, during the rotation of the spiral groove cam 81 about its axis, the engagement of the spiral groove cam 81 and the drive member 82 allows the drawer 7 to slide relative to the fixed part 6 in the depth direction.

[0033] In some embodiments, the rocker arm mechanism further includes a rotary handle 83, which is detachably coupled to a helical groove cam 81 to drive the helical groove cam 81 to rotate about an axis. In some embodiments, the drawer 7 is also provided with a handle socket 71, through which the rotary handle 83 can pass and couple with the helical groove cam 81.

[0034] Figure 2 The interlocking device according to some embodiments of the present disclosure is also shown in a locked state. Figure 4 A schematic diagram of an interlocking device according to some embodiments of the present disclosure in an unlocked state is shown. For example... Figure 2 and Figure 4 As shown, the interlocking device 1 is arranged inside the drawer 7 and is adapted to switch to the interlocking state after the drawer 7 has been moved to a predetermined position. In the interlocking state, the interlocking device 1 can lock the drawer 7 to the fixing part 6 and simultaneously lock the rocker arm mechanism. The interlocking device 1 can restrict the relative sliding of the drawer 7 and the fixing part 6 while also restricting the rotation of the rotary handle 83 that drives the spiral groove cam 81 to rotate.

[0035] In some embodiments, the fixing part 6 has a plurality of fixing holes 61 on the side facing the drawer 7, and the plurality of fixing holes 61 correspond to a plurality of predetermined positions of the drawer 7. When the interlocking device 1 is in the interlocked state, a part of the interlocking device 1 can be inserted into the fixing hole 61, thereby fixing the drawer 7 to the fixing part 6. In this way, the drawer 7 can be stably held in a predetermined position (e.g., working position, detection position, or disconnected position). When the interlocking device 1 is in the unlocked state, the interlocking device 1 can expose the handle socket 71 of the drawer 7 so that the rotating handle 83 can be inserted into the handle socket 71 and coupled to the helical groove cam 81.

[0036] Figure 5 , Figure 6 Schematic diagrams of the overall structure of the interlocking device 1 according to some embodiments of the present disclosure in the locked and unlocked states are shown respectively. Figure 5 and Figure 6As shown, the interlocking device 1 includes a bracket 2, a drive plate 3 slidably connected to the bracket 2 along a first direction X, a locking plate 4 slidably connected along a second direction Y, and a blocking plate 5 slidably connected along a third direction Z. The first direction X and the second direction Y have a first predetermined angle, and a second predetermined angle exists between the first direction X and the second direction Y.

[0037] like Figure 2 As shown, in some embodiments, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other. For example, the first direction X can be a horizontal direction parallel to the sliding direction of drawer 7 (i.e., the depth direction), the second direction Y can be a horizontal direction perpendicular to the first direction X, and the third direction Z can be another horizontal direction perpendicular to the depth direction. In some other embodiments, the second direction Y and the third direction Z can be parallel to each other (i.e., the second direction Y and the third direction Z can have a zero-degree angle), or the second direction Y and the third direction Z can be inclined (i.e., the second direction Y and the third direction Z can have a non-zero angle).

[0038] Figure 7 An exploded view of an interlocking device according to some embodiments of the present disclosure is shown. Figure 7 As shown, in some embodiments, the bracket 2 includes a body coupled to the bottom wall of the drawer 7, and the body has at least one first sliding hole 21, the axis of which extends along a first direction X. In some embodiments, the at least one first sliding hole 21 includes two first sliding holes 21, through which the drive plate 3 passes, thereby allowing the drive plate 3 to slide within the two first sliding holes 21 along the first direction X.

[0039] Figure 8 Schematic diagrams of interlocking devices according to some embodiments of the present disclosure are shown from other perspectives. For example... Figure 7 and Figure 8 As shown, in some embodiments, the interlocking device further includes a spring 33, which is arranged between the bracket 2 and the drive plate 3 and adapted to provide an elastic force to the drive plate 3 so that the drive plate 3 can remain in the locked position when not operated by the user. For example, the spring 33 can be compressed during the sliding of the drive plate 3 from the locked position to the unlocked position under user operation. After the user operation ends, the spring 33 pushes the drive plate 3 back from the unlocked position to the locked position. In some embodiments, the drive plate 3 includes a mounting post 32 extending along a first direction X, and the spring 33 can be sleeved on the extension post. In this way, the stability of the elastic force provided by the spring 33 to the drive plate 3 can be improved.

[0040] like Figure 7As shown, in some embodiments, the main body is further provided with at least one second sliding hole 22, and the axis of the at least one second sliding hole 22 extends along the second direction Y. In some embodiments, the main body is provided with two second sliding holes 22, and the locking plate 4 passes through the two second sliding holes 22, and the locking plate 4 can slide along the second direction Y within the two second sliding holes 22.

[0041] In some embodiments, the bracket 2 further includes a first slide rail 24 and a first stepped screw 25 disposed within the first slide rail 24. The first slide rail 24 is formed on the body and extends along a first direction X. The first stepped screw 25 is coupled to a locking plate 4, and the first stepped screw 25, constrained by the first slide rail 24, allows the locking plate 4 to slide along the first direction X.

[0042] In some embodiments, the body further includes at least one third sliding hole 23, the axis of which extends in the third direction Z. In some embodiments, two third sliding holes 23 are formed on the body, and the baffle plate 5 passes through the two third sliding holes 23, thereby allowing the baffle plate 5 to slide in the two third sliding holes 23 in the third direction Z.

[0043] The drive plate 3 is coupled to the locking plate 4 and the blocking plate 5 respectively. Thus, during the sliding motion of the drive plate 3 from the locked position to the unlocked position by user operation, the drive plate 3 can drive the locking plate 4 to slide from the position partially inserted into the fixing hole 61 along the second direction and exit the fixing hole 61. Furthermore, the drive plate 3 can also drive the blocking plate 5 along the third direction Z from a position that at least partially covers the handle socket 71 to a position that exposes the handle socket 71. In this way, the interlocking device can switch from an interlocked state to an unlocked state under user operation (e.g., pushing the drive plate 3 along the first direction X, causing the drive plate 3 to slide from the locked position to the unlocked position). This releases the lock on the drawer 7 and the fixing part 6, exposing the handle socket 71 so that the rotating handle 83 can be inserted into the handle socket 71.

[0044] like Figure 7As shown, in some embodiments, the drive plate 3 includes a second slide rail 31, which is arranged near the locking plate 4 and includes an unlocking end and a locking end. A first stepped screw 25 is at least partially disposed within the second slide rail 31. The distance from the unlocking end to the fixing part 6 is greater than the distance from the locking end to the fixing part 6, so that during the sliding of the drive plate 3 from the locked position to the unlocking position, the first stepped screw 25 moves from the locking end of the second slide rail 31 to the unlocking end of the second slide rail 31. As a result, the locking plate 4 exits the fixing hole 61 in the second direction Y. However, if the drive plate 3 slides from the unlocking position to the locking position in the first direction X, the first stepped screw 25 moves from the unlocking end of the second slide rail 31 to the locking end of the second slide rail 31, causing the locking plate 4 to partially insert into the fixing hole 61.

[0045] like Figure 7 As shown, in some embodiments, a third slide rail 51 is formed on the blocking plate 5, and the extending direction of the third slide rail 51 has a predetermined non-zero angle with the first direction X and the third direction Z, respectively. In some embodiments, the extending direction of the third slide rail 51 may be between the angles formed by the first direction X and the third direction Z. For example, the extending direction of the third slide rail 51 may be on the angle bisector of the angle formed by the first direction X and the third direction Z. The third slide rail 51 includes a shielding end and an exposed end. A second stepped screw 52 is arranged in the third slide rail 51 and coupled to the drive plate 3, so that during the sliding of the drive plate 3 from the locked position to the unlocked position, the second stepped screw 52 moves from the shielding end of the third slide rail 51 to the exposed end, and drives the blocking plate 5 to slide along the third direction Z, so that the blocking plate 5 moves from a shielding position that at least partially shields the handle socket 71 to an exposed position that exposes the handle socket 71.

[0046] Various implementations of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed implementations. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described implementations. The terminology used herein is chosen to best explain the principles, practical applications, or improvements to technology in the market, or to enable others skilled in the art to understand the various implementations disclosed herein.
