Description

Technical Field

[0001] The present application relates to the technical field of storage devices, and in particular to an interlocking structure and a storage cabinet. Background Art

[0002] Common storage cabinets are usually provided with drawers, which can extend out of the cabinet body. However, when not in use, for example, during transportation, the cabinet body is hit and tilted, causing the drawer to accidentally slide out of the cabinet body and open. Utility Model Content

[0003] Based on this, it is necessary to provide an interlocking structure to solve the problem that the drawer is easy to accidentally slide out of the cabinet and open when not in use.

[0004] An interlocking structure is used to lock a drawer to a cabinet body of a storage cabinet. The interlocking structure includes a push rod and a locking plate. One end of the locking plate is used to connect the drawer, and the other end is used to lock with the push rod. The push rod is slidably installed on the cabinet body and can be switched between a first position and a second position. When the push rod is in the first position, the locking plate is locked with the push rod to restrict the drawer from extending out of the cabinet body along a first direction X; when the push rod is in the second position, the locking plate is unlocked from the push rod, and the locking plate can follow the drawer to move along the first direction X to disengage from the push rod.

[0005] In one embodiment, the interlocking structure further comprises a fixed seat, the fixed seat is fixedly connected to the cabinet, and the push rod is movably connected to the fixed seat. It can be understood that, in such a configuration, the fixed seat is used as a support member to support the push rod and enable the push rod to slide relative to the cabinet.

[0006] In one embodiment, the fixing seat has a receiving groove, the push rod is movably received in the receiving groove, and can be switched between the first position and the second position along the second direction Y, the locking plate is provided with a locking hook, and the locking hook extends into the receiving groove; when the push rod is in the first position, the locking hook is hooked on the first end of the push rod along the first direction X; when the push rod is in the second position, the locking hook is staggered with the first end in the second direction Y, wherein the second direction Y is perpendicular to the first direction X. It can be understood that such a configuration facilitates the locking plate and the push rod to be locked or unlocked.

[0007] In one embodiment, the number of locking plates is configured to be multiple, and the multiple locking plates are arranged at intervals along the third direction Z, and each locking plate is connected to a corresponding drawer, wherein the first direction X, the second direction Y and the third direction Z are perpendicular to each other. It can be understood that, in this configuration, when the push rod moves from the first position to the second position, the multiple drawers are unlocked synchronously; when the push rod moves from the second position to the first position, the multiple drawers are locked and connected to the cabinet synchronously. Thereby, the unlocking or locking efficiency of the multiple drawers can be improved.

[0008] In one embodiment, the locking plate is provided with a guide structure, and the guide structure extends into the accommodating groove; when the push rod is in the second position, the guide structure and the second end of the push rod are arranged at intervals in the first direction X, and as any layer of drawers extends out of the cabinet along the first direction X, the guide structure connected to the drawer of this layer can abut against the second end of the push rod and push the push rod to move to the first position, wherein the second end and the first end are arranged relative to each other in the second direction Y. It can be understood that, in such a configuration, the guide structure can respond to the action of the drawer connected thereto extending out of the cabinet, and push the push rod to move from the second position to the first position, so that after any layer of drawers extends out of the cabinet, the drawers of the remaining layers are locked and connected to the cabinet.

[0009] In one of the embodiments, a second guide edge is provided on the side of the lock hook facing away from the drawer, and the second guide edge is inclined relative to the first end; as any layer of drawers is retracted into the cabinet body, the second guide edge connected to the drawer layer can abut against the first end and push the push rod to move to the second position.

[0010] In one embodiment, the length of the guide structure extending out of the drawer is greater than the length of the lock hook extending out of the drawer along the first direction X. It can be understood that such a configuration is conducive to ensuring that when the lock plate follows the drawer connected to it and extends out of the cabinet, and the guide structure on the lock plate pushes the push rod to move from the second position to the first position, the lock hook on the lock plate can be moved to the disengagement groove in time, thereby avoiding the lock hook on the lock plate from interfering with the first end of the push rod, so as to prevent the push rod from moving toward the first position.

[0011] In one embodiment, one of the fixed seat and the push rod is provided with a slide rail extending along the second direction Y, and the other of the fixed seat and the push rod is provided with a slider, which is slidably mounted on the slide rail along the second direction Y. It can be understood that, in such a configuration, the slide rail and the slider slide along the second direction Y to cooperate and guide, thereby enabling the push rod to move more smoothly relative to the fixed seat.

[0012] In one embodiment, the slide rail is configured as an elongated hole extending along the second direction Y, and the elongated hole is opened in the fixed seat; the slider is configured as a marble assembly, the marble assembly includes a marble and an outer shell, one end of the marble is used for sliding engagement with the elongated hole, and the other end is installed in the outer shell and connected to the push rod through the outer shell. It can be understood that, in this arrangement, the elongated hole has a simple structure and is easy to process, and the marble is slidably engaged with the elongated hole, which can reduce the resistance of the push rod when it slides relative to the fixed seat.

[0013] In one embodiment, the elongated hole forms a limiting structure between the first position and the second position, and when the push rod is in the first position, the marble stops at the side of the limiting structure away from the second position; when the push rod is in the second position, the marble stops at the side of the limiting structure away from the first position; the marble assembly also includes an elastic member, and the elastic member elastically acts on the marble. As the push rod is subjected to a force in the second direction Y, the marble can retract to the outer shell in response to the squeezing of the limiting structure, and pass over the limiting structure and get stuck in the elongated hole again. It can be understood that, in such a configuration, the limiting structure limits the marble, and can prevent the marble from sliding along the elongated hole by itself, thereby preventing the push rod from moving from the first position to the second position, or from the second position to the first position, in a natural state where it is not subject to force. When the push rod is subjected to a force along the second direction Y, the marble is squeezed by the limiting structure and squeezes the elastic member to retract into the outer shell. As the push rod continues to move along the second direction Y, the marble passes over the limiting structure, and the squeezing effect between the marble and the limiting structure disappears. The elastic member pushes the marble out of the outer shell and is stuck in the elongated hole again.

[0014] In one embodiment, the elongated hole includes a first section, a second section and a necking section between the first section and the second section. The widths of the first section and the second section are equal and both are larger than the necking section. The hole wall of the necking section constitutes a limiting structure.

[0015] In one embodiment, a transmission shaft is further included, one end of the transmission shaft is connected to the push rod, and the other end extends out of the cabinet, and the transmission shaft is used to drive the push rod to switch between the first position and the second position along the second direction Y. It can be understood that, in this configuration, the user can drive the push rod to switch between the first position and the second position by applying a force to the transmission shaft, that is, the user can achieve the lock connection of the drawer to the cabinet, or achieve the unlocking of the drawer and the cabinet by applying a force to the transmission shaft.

[0016] In one embodiment, a matching hole extending along the third direction Z is provided on the push rod, and the transmission shaft includes a guide section and a connecting section arranged parallel to each other in the first direction X, the guide section is inserted into the matching hole, and the connecting section is rotatably connected to the fixing seat; as the guide section rotates around the connecting section, the guide section flexibly matches with the matching hole along the third direction Z, and pushes the push rod to move along the second direction Y. It can be understood that, in such a configuration, by providing the matching hole along the third direction Z, the matching hole adapts to the up and down movement of the guide section along the third direction Z, and converts the left and right movement of the guide section along the second direction Y into the left and right movement of the push rod along the second direction Y through its hole wall.

[0017] In one embodiment, a fastener is further included, the push rod is provided with a through hole extending along the second direction Y, one end of the fastener is fixedly connected to the fixing seat, and the other end is passed through the through hole and connected to the push rod. It can be understood that such a configuration allows the push rod to be connected to the fixing seat and can only move relative to the fixing seat along the second direction Y.

[0018] The present application also provides a storage cabinet, which also includes a drawer, a cabinet body and the interlocking structure described in any one of the above embodiments, the cabinet body has an opening, the drawer is slidably mounted on the cabinet body, and can be extended through the opening.

[0019] Compared with the prior art, the interlocking structure and storage cabinet provided in the present application move the push rod to the first position, locking the locking plate and the push rod, so that the drawer connected to the locking plate can be locked to the cabinet body and cannot slide out of the cabinet body. In this way, the storage cabinet can be prevented from being accidentally opened when not in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] See also Figure 1 , Figure 2 , Figure 3 , Fig. 9 and Fig.11 ,This application provides an interlocking structure, wherein, Figure 1 A schematic diagram of the structure of the storage cabinet provided for this application; Figure 2 for Figure 1 Partial exploded view of Figure 3 An axonometric view of the interlocking structure provided for this application; Fig. 9 is a schematic diagram of the push rod 10 when it is in the second position; Fig.11 Schematic diagram of the push rod 10 in the first position.

[0040] Specifically, the interlocking structure 100 is used to lock the drawer 200 to the cabinet 300 of the storage cabinet. The interlocking structure 100 includes a push rod 10 and a locking plate 20, one end of the locking plate 20 is used to connect the drawer 200, and the other end is used to lock and cooperate with the push rod 10, the push rod 10 is slidably mounted on the cabinet 300, and can be switched between a first position and a second position. When the push rod 10 is in the first position, the locking plate 20 is locked with the push rod 10 to limit the drawer from extending out of the cabinet 300 along the first direction X. When the push rod 10 is in the second position, the locking plate 20 is unlocked from the push rod 10, and the locking plate 20 can follow the drawer 200 to move along the first direction X to disengage from the push rod 10. That is, by moving the push rod 10 to the first position, the locking plate 20 is locked with the push rod 10, so that the drawer 200 connected to the locking plate 20 can be locked to the cabinet body 300 and cannot slide out of the cabinet body 300. In this way, the storage cabinet 1 can be prevented from being accidentally opened when not in use.

[0041] Optionally, in one embodiment, Figure 2 As shown, the cabinet 300 has an opening 310, and the drawer 200 is slidably mounted on the cabinet 300 and can extend out of the cabinet 300 through the opening 310. The interlocking structure 100 is mounted on a side wall of the cabinet 300 disposed toward the opening 310. In this embodiment, the first direction X refers to a direction from the interlocking structure 100 to the opening 310.

[0042] See also Figure 2 and Figure 3 The interlocking structure 100 further includes a fixing seat 30, which is fixedly connected to the cabinet 300, and the push rod 10 is movably connected to the fixing seat 30. The fixing seat 30 is used as a support member to support the push rod 10 and enable the push rod 10 to slide relative to the cabinet 300.

[0043] Optionally, in one embodiment, if Figure 6 As shown, the fixing base 30 is detachably connected to the cabinet 300 by bolts 60. However, it is not limited thereto. In other embodiments, the fixing base 30 may also be connected to the cabinet 300 by snapping.

[0044] See also Fig. 9 and Fig.11 The fixing seat 30 has a receiving groove 31, the push rod 10 is movably received in the receiving groove 31, and can switch between the first position and the second position along the second direction Y, and the locking piece 20 is provided with a locking hook 21, and the locking hook 21 extends into the receiving groove 31. Fig.11 As shown, when the push rod 10 is in the first position, the lock hook 21 is hooked on the first end 11 of the push rod 10 along the first direction X. Fig. 9 As shown, when the push rod 10 is located at the second position, the locking hook 21 is offset from the first end 11 in the second direction Y, wherein the second direction Y is perpendicular to the first direction X.

[0045] Since the lock hook 21 is hooked on the first end 11 of the push rod 10 along the first direction X when the push rod 10 is located at the first position, the first end 11 forms a stopper for the lock hook 21 along the first direction X, so that the drawer 200 connected to the locking plate 20 cannot extend out of the cabinet 300. Moreover, since the lock hook 21 is staggered from the first end 11 in the second direction Y when the push rod 10 is located at the second position, the first end 11 cannot form a stopper for the lock hook 21 along the first direction X, so that the lock hook 21 can freely exit the accommodating groove 31 along the first direction X, that is, the drawer 200 connected to the locking plate 20 can freely extend out of the cabinet 300.

[0046] Optionally, two side walls of the accommodating groove 31 that are arranged opposite to each other along the second direction Y are used to stop the first end 11 and the second end 12 of the push rod 10 respectively, so that the push rod 10 can stop at the first position and the second position respectively.

[0047] Of course, in other embodiments, two stoppers may be provided in the receiving groove 31 and spaced apart along the second direction Y. The two stoppers are used to stop the first end 11 and the second end 12 of the push rod 10 respectively.

[0048] See also Figure 2 and Figure 3 The number of the locking pieces 20 is configured to be multiple, and the multiple locking pieces 20 are arranged at intervals along the third direction Z, and each locking piece 20 is connected to a corresponding drawer 200, wherein the first direction X, the second direction Y and the third direction Z are perpendicular to each other. In this way, when the push rod 10 moves from the first position to the second position, the multiple drawers 200 are unlocked synchronously; when the push rod 10 moves from the second position to the first position, the multiple drawers 200 are locked and connected to the cabinet body 300 synchronously. Thereby, the unlocking or locking efficiency of the multiple drawers 200 can be improved.

[0049] The following describes the process of a single locking piece 20 following the drawer 200 connected thereto to extend outward from the receiving groove 31 or to retract into the receiving groove 31. Figures 9 to 12 ,in, Fig. 9 is a schematic diagram when all locking plates are located at the second position; Fig.10 It is a schematic diagram of a process in which a single locking piece 20 extends outward; Fig.11 for Fig.10 A schematic diagram showing a single locking piece 20 being completely located outside the receiving groove 31; Fig.12 for Fig.11 The schematic diagram of the single locking piece 20 retracting to the receiving groove 31 is shown. Figures 9 to 11 Schematic diagram of the process of a single locking piece 20 extending outward from the receiving groove 31; Figure 11 to Figure 12 Then Fig. 9 It is a schematic diagram of the process of a single locking piece 20 returning to the receiving groove 31 .

[0050] Specifically, the locking piece 20 is provided with a guide structure 22, and the guide structure 22 extends into the accommodating groove 31; when the push rod 10 is in the second position, the guide structure 22 and the second end 12 of the push rod 10 are arranged at intervals in the first direction X, and as any layer of drawers 200 extend out of the cabinet 300 along the first direction X, the guide structure 22 connected to the drawer 200 of the layer can abut against the second end 12 of the push rod 10 and push the push rod 10 to move to the first position, wherein the second end 12 and the first end 11 are arranged relative to each other in the second direction Y. In this way, the guide structure 22 can respond to the action of the drawer 200 connected thereto extending out of the cabinet 300, and push the push rod 10 to move from the second position to the first position, so that after any layer of drawers 200 extend out of the cabinet 300, the remaining layers of drawers 200 are locked and connected to the cabinet 300.

[0051] Furthermore, along the first direction X, the length of the guide structure 22 extending out of the drawer 200 is greater than the length of the lock hook 21 extending out of the drawer 200. In this way, it is beneficial to ensure that when the lock plate 20 follows the connected drawer 200 to extend out of the cabinet 300, and when the guide structure 22 on the lock plate 20 pushes the push rod 10 to move from the second position toward the first position, the lock hook 21 on the lock plate 20 can be moved to disengage from the accommodating groove 31 in time, thereby avoiding the lock hook 21 on the lock plate 20 from interfering with the first end 11 of the push rod 10, so as to prevent the push rod 10 from moving toward the first position.

[0052] Optionally, along the first direction X, the thickness of the second end 12 is greater than the thickness of the first end 11 . In this way, the guide structure 22 is conveniently abutted against the second end 12 of the push rod 10 .

[0053] Furthermore, the guide structure 22 is provided with a first guide edge 221 , and the first guide edge 221 is arranged obliquely relative to the second end 12 and is used for abutting against the second end 12 .

[0054] A second guide edge 211 is provided on the side of the lock hook 21 facing away from the drawer 200, and the second guide edge 211 is inclined relative to the first end 11. As any layer of drawers 200 is retracted to the cabinet 300, the second guide edge 211 connected to the drawer 200 can abut against the first end 11 and push the push rod 10 to move to the second position. In this way, the second guide edge 211 can respond to the action of the drawer 200 connected thereto being retracted to the cabinet 300, and push the push rod 10 from the first position to the second position, so that after any layer of drawers 200 is retracted to the cabinet 300, the remaining layers of drawers 200 are unlocked from the cabinet 300.

[0055] The following describes the process of sliding engagement of the push rod 10 relative to the fixing seat 30 along the second direction Y. Figures 3 to 7 .

[0056] One of the fixed seat 30 and the push rod 10 is provided with a slide rail 32 extending along the second direction Y, and the other of the fixed seat 30 and the push rod 10 is provided with a slider 13, and the slider 13 is slidably clamped on the slide rail 32 along the second direction Y. The slide rail 32 and the slider 13 slide along the second direction Y to cooperate with each other to guide, so that the push rod 10 can move more smoothly relative to the fixed seat 30.

[0057] The number of the slide rails 32 and the sliders 13 can be set to multiple groups, and the multiple groups of slide rails 32 and the sliders 13 are distributed at intervals in the third direction Z.

[0058] Preferably, in one embodiment, Figures 4 to 7 As shown, the slide rail 32 is configured as an elongated hole 33 extending along the second direction Y, and the elongated hole 33 is opened in the fixing seat 30. The slider 13 is configured as a marble assembly 14, which includes a marble 141 and an outer shell 142. One end of the marble 141 is used for sliding engagement with the elongated hole 33, and the other end is installed in the outer shell 142 and connected to the push rod 10 through the outer shell 142. The elongated hole 33 has a simple structure and is easy to process, and the marble 141 is slidably engaged with the elongated hole 33, which can reduce the resistance of the push rod 10 when it slides relative to the fixing seat 30.

[0059] Furthermore, the elongated hole 33 forms a limiting structure 331 between the first position and the second position. When the push rod 10 is located at the first position, the marble 141 stops at the side of the limiting structure 331 away from the second position. When the push rod 10 is located at the second position, the marble 141 stops at the side of the limiting structure 331 away from the first position. The marble assembly 14 also includes an elastic member, which elastically acts on the marble 141. As the push rod 10 is subjected to a force in the second direction Y, the marble 141 can respond to the extrusion of the limiting structure 331 and retract to the outer shell 142, and pass the limiting structure 331 and get stuck in the elongated hole 33 again.

[0060] In this way, the limiting structure 331 limits the marble 141, and can prevent the marble 141 from sliding along the elongated hole 33 by itself, thereby preventing the push rod 10 from moving from the first position to the second position, or from the second position to the first position, in a natural state without force. In addition, when the push rod 10 is subjected to a force in the second direction Y, the marble 141 is squeezed by the limiting structure 331 and squeezes the elastic member to retract to the outer shell 142. As the push rod 10 continues to move along the second direction Y, the marble 141 passes over the limiting structure 331, and the squeezing effect between the marble 141 and the limiting structure 331 disappears, and the elastic member pushes the marble 141 out of the outer shell 142 and is clamped into the elongated hole 33 again. Among them, the elastic member can be configured as a retaining spring.

[0061] Optionally, in one embodiment, if Figure 5As shown, the elongated hole 33 includes a first section 332 , a second section 333 and a necked section 334 located between the first section 332 and the second section 333 . The widths of the first section 332 and the second section 333 are equal and both are larger than the necked section 334 . The hole wall of the necked section 334 constitutes a limiting structure 331 .

[0062] See also Figure 4 The interlocking structure 100 further includes a fastener 50. The push rod 10 is provided with a through hole 16 extending along the second direction Y. One end of the fastener 50 is fixedly connected to the fixing seat 30, and the other end is passed through the through hole 16 and connected to the push rod 10. In this way, the push rod 10 can only move relative to the fixing seat 30 along the second direction Y while being connected to the fixing seat 30.

[0063] In another embodiment, the through hole 16 may also be opened in the fixing seat 30 , and the fastener 50 is fixedly connected to the push rod 10 .

[0064] Optionally, in one embodiment, the fastener is configured as a bolt 60 .

[0065] See also Figure 3 and Figure 8 The interlocking structure 100 further includes a transmission shaft 40, one end of which is connected to the push rod 10, and the other end of which extends out of the cabinet 300. The transmission shaft 40 is used to drive the push rod 10 to switch between the first position and the second position along the second direction Y. In this way, the user can drive the push rod 10 to switch between the first position and the second position by applying a force to the transmission shaft 40, that is, the user can achieve the lock connection of the drawer 200 to the cabinet 300, or achieve the unlocking of the drawer 200 and the cabinet 300 by applying a force to the transmission shaft 40.

[0066] Preferably, in one embodiment, the push rod 10 is provided with a matching hole 15 extending along the third direction Z, and the transmission shaft 40 includes a guide section 41 and a connecting section 42 arranged parallel to each other in the first direction X, the guide section 41 is passed through the matching hole 15, and the connecting section 42 is rotatably connected to the fixing seat 30. As the guide section 41 rotates around the connecting section 42, the guide section 41 movably cooperates with the matching hole 15 along the third direction Z, and pushes the push rod 10 to move along the second direction Y.

[0067] In this embodiment, when the guide segment 41 rotates around the connecting segment 42, its motion trajectory is a circle around the connecting segment 42, which can be specifically decomposed into up and down motion along the third direction Z and action motion along the second direction Y. By setting the matching hole 15, the matching hole 15 adapts to the up and down motion of the guide segment 41 along the third direction Z, and converts the left and right motion of the guide segment 41 along the second direction Y into the left and right motion of the push rod 10 along the second direction Y through its hole wall.

[0068] Furthermore, the interlocking structure 100 also includes a lock head 70, which is located at one end of the guide section 41 away from the connecting section 42 and is connected to the side wall of the guide section 41. In this way, the guide section 41 can be driven to rotate around the connecting section 42 by screwing the lock head 70, which is more labor-saving.

[0069] In other embodiments, the motion trajectory of the transmission shaft 40 may also be to move left and right along the second direction Y, thereby directly driving the push rod 10 to switch between the first position and the second position along the second direction Y.

[0070] The present application also provides a storage cabinet 1, which includes a drawer 200, a cabinet body 300 and the interlocking structure 100 described in any one of the above embodiments.

[0071] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
