Abstract
Description
Technical Field
[0001] This application relates to the field of toolbox structures, and in particular to a linkage mechanism and a toolbox. Background Technology
[0002] Stackable toolboxes typically use snap-fit or latch locking mechanisms to secure the boxes together. For example, symmetrical latches and slots are set on both sides of the box, and locking and unlocking are achieved by pressing or sliding.
[0003] Based on an understanding of the relevant technologies, locking mechanisms typically require users to manually press or flick the latches. When stacking or disassembling the boxes, both hands are needed for operation. Especially during handling, users may find it difficult to simultaneously hold the box and operate the latches, affecting ease of use.
[0004] Although some stackable toolboxes have improved locking mechanisms that can automatically lock adjacent boxes when stacked, these mechanisms still require manual intervention to unlock. Furthermore, when lifting the top box, both hands must simultaneously activate the locking mechanism to unlock it, and both hands must work in tandem when stacking or disassembling the boxes. Summary of the Invention
[0005] The purpose of at least one specific embodiment of the present invention is to overcome the deficiencies of the prior art and provide a stackable toolbox.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A linkage mechanism, comprising: The locking module has a first mounting slot and a second mounting slot inside; The actuating component includes a push rod slidably mounted within the locking module, and an actuating element connected to one end of the push rod; The locking assembly includes a locking element that is reciprocally mounted within the second mounting slot; The transmission assembly includes a cable connected between the push rod and the locking member, the cable being used to convert the linear motion of the push rod into a tensile force that controls the retraction of the locking member; The elastic reset assembly includes a first elastic reset member disposed in the first mounting groove and a second elastic reset member disposed in the second mounting groove; Wherein, the elastic force of the first elastic reset member is greater than that of the second elastic reset member; when the actuating member is pressed, the push rod compresses the first elastic reset member and releases the cable, and the locking member extends under the drive of the second elastic reset member; When the actuating element loses pressure, the push rod is reset under the drive of the first elastic reset element and the locking element is retracted by the cable overcoming the elastic force of the second elastic reset element.
[0007] Furthermore, the locking module has a support part inside, and the two ends of the support part form arc-shaped parts. The cable passes around the arc-shaped parts to connect the push rod and the locking member to change the transmission direction.
[0008] Furthermore, the push rod is provided with a slider, the locking module is provided with a guide part that cooperates with the slider, and the first elastic reset member is sleeved on the outside of the push rod and abuts against the slider.
[0009] Furthermore, the end of the locking member is provided with an inclined surface, so that when the locking member is subjected to vertical compression in the extended state, it can automatically retract into the locking module.
[0010] Compared with the prior art, the beneficial technical effects of the linkage mechanism of this application are as follows: This application sets up a transmission cooperation between the push rod, the cable and the locking member, and utilizes the elastic force difference between the first elastic reset member and the second elastic reset member, so that when the trigger member is pressed, it can release the cable and drive the locking member to automatically extend under the action of the second elastic reset member. When the trigger member loses pressure, the push rod is reset under the drive of the first elastic reset member and pulls the locking member back through the cable, thereby realizing the automatic extension and retraction control of the locking member. This makes the linkage mechanism simple in structure, reliable in action, and able to complete the linkage control of locking and unlocking through a single touch action.
[0011] Another technical solution adopted in this application is as follows: A toolbox comprising: The box body has a handle mounting position on its side; A handle is rotatably connected to the handle mounting position. The aforementioned linkage mechanism is installed inside the housing; The linkage mechanism has an actuating element that extends from the side of the housing to the handle mounting position. When the handle moves closer to the side of the housing, it presses the actuating element to extend the locking element and lock it. When the handle flips outward relative to the side of the housing, the actuating element is released, causing the locking element to retract and unlock.
[0012] Furthermore, an elastic element is installed at the connection between the handle and the housing. The elastic element drives the handle to remain in the closed state and squeezes the trigger element when no external force is applied.
[0013] Furthermore, the handle mounting position or the handle is provided with a positioning mechanism, which is used to maintain the handle in contact with the side of the box when the handle is closed.
[0014] Furthermore, the bottom of the box is provided with a protrusion, and the top of the box is provided with a recessed groove, the protrusion and the recessed groove being adapted to each other; the locking member is installed on one side of the protrusion.
[0015] Furthermore, the bottom of the box is provided with a limiting part, and the top is provided with a limiting groove that cooperates with the limiting part; the limiting part and the locking member are respectively located on both sides of the bottom of the box.
[0016] Furthermore, it has a one-handed linkage unlocking function, that is, when the handle is pulled upward, the linkage mechanism drives the locking member to unlock, so that one side of the box can tilt upward, thereby driving the limiting part to disengage from the limiting groove to achieve overall unlocking.
[0017] Compared to existing technologies, the beneficial technical effects of this toolbox are as follows: The stackable toolbox provided in this application has a linkage mechanism connected to a locking element on the first box, and the handle is driven to the linkage mechanism. This allows the handle to move relative to the first box, driving the locking element to move between a locked and unlocked position via the linkage mechanism. Therefore, when the user holds the handle to move the toolbox, the locking element is triggered simultaneously, thus achieving locking or unlocking between the first and second boxes. Compared to structures that require separate operation of the locking mechanism, this application links the moving action with the locking action, allowing the user to lock or unlock the boxes while moving the toolbox. This enables one-handed operation, reduces operating steps, and improves the convenience and efficiency of using the stackable toolbox. Attached Figure Description

[0032] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] Reference Figures 1 to 8 A stackable toolbox 100 includes a first box 10 and a second box 20 that can be detachably stacked, wherein a locking tongue 101 is provided on one side of the first box 10; The second housing 20 is provided with a locking groove 201 (locking part) corresponding to the locking tongue 101 (locking part). When the housings are stacked, the locking tongue 101 locks with the locking groove 201. The first housing 10 is provided with a linkage mechanism 200 connected to the lock tongue. The linkage mechanism 200 can control the movement of the lock tongue 101, so that the lock tongue 101 is locked or unlocked relative to the lock groove 201. In this embodiment, a handle 102 is installed on one side of the first housing 10, and the handle 102 can rotate relative to the first housing 10. When the handle 102 moves closer to the side of the first housing 10, it can trigger the linkage mechanism 200, which controls the locking tongue 101 to lock relative to the locking groove 201. When the handle 102 is flipped outward relative to the side of the first housing 10, the linkage mechanism 200 controls the locking tongue 101 to unlock relative to the locking groove 201.
[0034] Specifically, the linkage mechanism 200 is used to transmit the movement of the handle 102 to the locking tongue 101 when the handle 102 rotates, thereby driving the locking tongue 101 to move between the locked position and the unlocked position. By linking the rotation of the handle 102 with the movement of the locking tongue 101, the user can lock or unlock adjacent boxes without additional operation of the locking mechanism when moving the first box 10.
[0035] With the above structural design, the handle 102 is not only used by the user to hold and move the first box 10, but also serves as an operating component that triggers the action of the linkage mechanism 200. When the user holds the handle 102 and lifts the first box 10, the outward flipping action of the handle 102 can automatically trigger the retraction of the locking tongue 101, thereby allowing the first box 10 to be smoothly separated from the second box 20.
[0036] Furthermore, the side of the first housing 10 has a handle mounting position 103, and the linkage mechanism 200 includes an actuating element 210. One end of the actuating element 210 is located at the handle mounting position 103. When the handle 102 moves closer to the side of the first housing 10, it can squeeze the actuating element 210, so that the linkage mechanism 200 is activated and controls the locking tongue 101 to lock relative to the locking groove 201.
[0037] In some embodiments, refer to Figure 2 An elastic element 300 is installed at the connection between the handle 102 and the first housing 10. The elastic element 300 can be a torsion spring. When the handle 102 is not subjected to external force, the elastic element can drive the handle 102 to move closer to the side of the first housing 10 and squeeze the trigger 210, so that the linkage mechanism 200 is triggered and controls the locking tongue 101 to lock relative to the locking groove 201.
[0038] In other embodiments, reference is made to Figure 3A positioning mechanism is provided on the inner wall of the handle mounting position 103 and / or the handle 102. When the handle 102 is rotated to approach the side of the first housing 10 and press the actuating member 210, the positioning mechanism maintains the handle 102 in contact with the side of the first housing 10. In a specific design, the positioning mechanism can be a protrusion 400 provided on the inner wall of the handle mounting position 103 and / or the outer wall of the handle 102. When the handle 102 is in contact with the handle mounting position 103, the protrusion 400 can increase the resistance between the handle 102 and the inner wall of the handle mounting position 103. When the handle 102 presses the actuating member 210, the restoring force of the actuating member 210 will not push the handle 102 up and cause the handle 102 to flip.
[0039] Furthermore, the top of the second box 20 is provided with a recessed groove 202, and the bottom of the first box 10 is provided with a protrusion 104. When the first box 10 and the second box 20 are stacked, the protrusion 104 at the bottom of the first box 10 matches the recessed groove 202 of the second box 20. Through the above-mentioned matching structure of the protrusion 104 and the recessed groove 202, the first box 10 and the second box 20 can be initially positioned when they are stacked, so that the two boxes can be automatically aligned during the stacking process, thereby ensuring that the locking tongue 101 can accurately enter the locking groove 201.
[0040] Furthermore, a limiting part 105 is provided on one side of the first box 10, and a limiting groove 203 corresponding to the limiting part 105 is provided on the second box 20. The limiting part 105 and the locking tongue 101 are located on both sides of the central axis of the first box 10. Correspondingly, the locking groove 201 and the limiting groove 203 are located on both sides of the recessed groove 202. The locking tongue 101 and the limiting part 105 are installed on both sides of the protrusion 104. By setting the locking tongue 101 and the limiting part 105 on both sides of the central axis of the first box 10, a double-sided constraint structure can be formed after the boxes are stacked, thereby improving the stability after stacking and preventing the boxes from shaking during handling or vibration.
[0041] It should be noted that, in order to describe the structure of the stacking toolbox, the structures of the first box 10 and the second box 20 are described separately in the above embodiments. In the actual production process, when multiple boxes need to be stacked, the structures of the first box 10 and the second box 20 can be designed in the same way. That is, the top of the first box 10 also has the design of the locking groove 201, the recessed groove 202 and the limiting groove 203. Similarly, the bottom of the second box 20 also has the design of the locking tongue 101, the protrusion 104 and the linkage mechanism 200. Similarly, the side of the second box 20 also has the structural design of the handle 102 and the handle mounting position 103.
[0042] It should be noted that in this embodiment, when the handle 102 triggers the linkage mechanism 200 to lock the locking tongue 101 and the locking groove 201, it can achieve one-sided locking between the stacked first box 10 and second box 20, the limiting part 105 and the limiting groove 203 are locked, and when the locking tongue 101 and the locking groove 201 are locked, the two sides of the stacked first box 10 and second box 20 are locked simultaneously.
[0043] Furthermore, refer to Figure 12 , Figure 13 The linkage mechanism 200 also includes a locking module 211, which has a first mounting slot 216 and a second mounting slot 217 inside. The actuation component includes a push rod 213 slidably mounted in the locking module 211, and an actuating element 210 connected to one end of the push rod 213; The locking assembly includes a locking member that is reciprocally mounted in the second mounting slot 217. In this embodiment, the locking member is specifically a locking tongue 101. The transmission assembly includes a cable 212 connected between the push rod 213 and the locking tongue 101. The cable 212 is used to convert the linear motion of the push rod 213 into a pulling force that controls the retraction of the locking tongue 101. The elastic reset assembly includes a first elastic reset member disposed in a first mounting groove 216 and a second elastic reset member disposed in a second mounting groove 217. In this embodiment, the first elastic reset member is specifically a push rod spring 214 and the second elastic reset member is specifically a locking tongue spring 215. The push rod spring 214 is disposed in the first mounting groove 216 and sleeved on the outside of the push rod 213. The locking tongue spring 215 is disposed in the second mounting groove 217, with one end abutting against the inner wall of the second mounting groove 217 and the other end abutting against the end of the locking tongue 101.
[0044] Furthermore, the locking module 211 has a support part 218 inside, and the two ends of the support part 218 form arc-shaped parts 219. After one end of the cable 212 is connected to the push rod 213, the other end of the cable passes around the arc-shaped part 219 and is connected to the locking tongue 101.
[0045] Furthermore, the push rod 213 is provided with a slider 220, the locking module 211 is provided with a guide part 221, the slider 220 is slidably installed in the guide groove 222 of the guide part 221, one end of the push rod spring 214 abuts against the inner wall of the first mounting groove 216, and the other end abuts against the slider 220. The actuator 210 is configured as a rod connected to the slider 220, with one end of the actuator 210 away from the slider 220 extending from the side of the first housing 10 to the handle mounting position 103.
[0046] Under normal circumstances, both the push rod spring 214 and the latch spring 215 are in a compressed state after being installed in the locking module 211, and the compression force of the push rod spring 214 is greater than that of the latch spring 215. Through the elastic force cooperation between the push rod spring 214 and the latch spring 215, the latch 101 can be reliably reset and stably locked. When the handle 102 touches the actuating element 210, the movement of the push rod 213 can change the tension state of the cable 212 on the latch 101, thereby controlling the extension or retraction of the latch 101.
[0047] Specifically, when the actuating element 210 is not touched by the handle 102, under the compression force of the push rod spring 214, the push rod 213 moves toward the side of the first housing 10, the slider 220 slides in the guide groove 222, and the end of the actuating element 210 on one side of the slider 220 extends out from the side of the first housing 10. At the same time that the push rod 213 is pushed out by the push rod spring 214, the push rod 213 will pull the cable 212, the cable 212 will pull the latch 101, causing the latch 101 to retract into the locking module 211. After the latch 101 retracts, it will compress the latch spring 215. At this time, the linkage mechanism 200 is in an unopened state.
[0048] Specifically, refer to Figure 9 , Figure 10 , Figure 11 When the first box 10 and the second box 20 are stacked, the user holds the handle 102 of the first box 10 and lifts the first box 10. When the bottom surface of the first box 10 and the top surface of the second box 20 are inclined, the limiting part 105 on the bottom side of the first box 10 can be inserted into the limiting groove 203 on the top side of the second box 20. The stacking of the first box 10 and the second box 20 is completed when the bottom surface of the first box 10 gradually approaches the top surface of the second box 20 and is level. The protrusion 104 at the bottom of the stacked first box 10 matches the recessed groove 202 at the top of the second box 20. At this time, the limiting part 105 locks one side of the stacked first box 10. After stacking, when the handle 102 approaches the side of the first housing 10, the handle 102 can press the end of the actuating member 210. The actuating member 210 actuates the linkage mechanism 200, which controls the locking tongue 101 to extend into the locking groove 201 at the top of the second housing 20 and lock relative to the locking groove 201. At this time, the locking tongue 101 locks the other side of the first housing 10. It should be noted that, in order to ensure that the handle 102 can maintain a stable contact with the side of the first housing 10 after pressing the actuating member 210, in some embodiments, an elastic member is installed at the connection between the handle 102 and the first housing 10. The elastic element can be a torsion spring. When the user's palm leaves the handle 102, the elastic element can drive the handle 102 to move closer to the side of the first housing 10 and press the trigger 210, thereby triggering the linkage mechanism 200. Moreover, under the torsion of the elastic element (torsion spring), the handle 102 can be firmly attached to the side of the first housing 10 and maintain the state of pressing the trigger 20. The advantage of this design is that after the first housing 10 and the second housing 20 are stacked, the handle 102 can automatically retract after the user leaves the handle 102 and drive the locking tongue 101 to lock the stacked first housing 10, making operation convenient.
[0049] In addition, in some embodiments, a positioning mechanism is provided on the inner wall of the handle mounting position 103 and / or the handle 102. When the handle 102 is rotated to approach the side of the first housing 10 and press the actuating member 210, the positioning mechanism maintains the contact state between the handle 102 and the side of the first housing 10. In a specific design, the positioning mechanism can be a protrusion 400 provided on the inner wall of the handle mounting position 103 and / or the outer wall of the handle 102. When the handle 102 is in the contact state at the handle mounting position 103, the protrusion 400 can increase the resistance between the handle 102 and the inner wall of the handle mounting position 103. When the handle 102 presses the actuating member 210, the restoring force of the actuating member 210 will not push the handle 102 up and cause the handle 102 to flip, thereby keeping the state of pressing the actuating member 20 unchanged.
[0050] When the first box 10 after stacking needs to be removed from the second box 20, the user holds the handle 102 of the first box 10 and lifts the first box 10. The handle 102 flips outward, and the squeezing force of the handle 102 on the trigger 210 disappears. The linkage mechanism 200 controls the locking tongue 101 of the first box 10 to retract and unlock relative to the locking groove 201 of the second box 20. After the first box 10 is lifted on one side, the stacked first box 10 and second box 20 are unlocked on one side. When the user uses the handle 102 to flip the first box 10 on top of the second box 20, the limiting part 105 at the bottom of the first box 10 separates from the limiting groove 203 at the top of the second box 20. At this time, the other side of the first box 10 and the second box 20 are unlocked, and the first box 10 and the second box 20 can be separated.
[0051] The locking and unlocking process of the first housing 10 will be explained in detail below, based on the specific working principle of the linkage mechanism 200.
[0052] To achieve automatic locking when adjacent toolboxes are stacked, the actuator 210 of the push rod 213 is located at the handle mounting position 103 of the first box 10. After the adjacent toolboxes are stacked, the handle 102 on the first box 10 is in a retracted state (the handle 102 retracts towards the side of the first box 10). The retracted handle 102 will press the actuator 210 of the push rod 213, causing the push rod 213 to retract into the locking module 211. The retracted push rod 213 compresses the push rod spring 214 and also pushes the cable 212. At this time, the push rod spring 214 is stably compressed and the compression stroke remains unchanged. Under these circumstances, the push rod spring 214 will not exert tension on the cable 212. After the cable 212 is pushed by the push rod 213, the elastic force of the locking tongue spring 215 is released. The released locking tongue spring 215 will pop the locking tongue 101 out of the locking module 211. The popped locking tongue 101 will extend into the locking groove 201 of the lower second box 20, thereby locking the adjacent boxes above and below. When the two locked boxes are tilted, they will not fall off each other.
[0053] When the first housing 10 and the second housing 20 need to be separated, the handle 102 of the first housing 10 is unfolded by hand. When the handle 102 is unfolded, the squeezing force exerted on the actuating element 210 of the push rod 213 disappears, and the limit state of the extension and retraction stroke of the actuating element 210 is released. At this time, the elastic force of the push rod spring 214 is released, and the push rod spring 214 pushes the push rod 213, causing the end of the actuating element 210 of the push rod 213 away from the end of the cable 212 to be separated. As the push rod 213 extends from the locking module 211, it is pushed out by the push rod spring 214. At the same time, the push rod 213 pulls the cable 212, which pulls the locking tongue 101, causing the locking tongue 101 to retract into the locking module 211. That is, the locking tongue 101 in the locking module 211 of the first box 10 retracts from the locking groove 201 of the second box 20, and the locking state between the adjacent toolboxes above and below is released. The first box 10 can be lifted away by hand through the handle 102.
[0054] In summary, when a user holds the handle 102 of the first box 10 and stacks the first box 10 on the second box 20, the first box 10 and the second box 20 automatically lock when the user removes their hand from the handle 102. When the user holds the handle 102 of the first box 10 and lifts the first box 10 from one side, the first box 10 and the second box 20 automatically unlock, and the first box 10 is lifted and separated from the second box 20.
[0055] Through the coordinated design of the rotation of the handle 102 and the linkage mechanism 200, "one action, two functions" are achieved. When the handle 102 is brought close, it automatically locks (triggered when it is in contact with the first box 10), and when the handle 102 is flipped outward, it unlocks simultaneously (triggered naturally when it is lifted). Users do not need to press the lock separately; they can complete the entire stacking / disassembly process by holding the handle 102 with one hand.
[0056] The stackable toolbox provided in this application features a first box 10 and a second box 20 stacked together. When the handle 102 is closed, it automatically triggers a lock, and the outward-folding handle 102 simultaneously unlocks. No additional buttons or auxiliary tools are required during operation. When the stacking is complete, the handle 102 naturally closes to lock the toolbox. When the boxes are separated, the lifting action automatically unlocks the toolbox. When the user holds the handle 102 of the first box 10 and stacks the first box 10 on the second box 20, the user's hand leaves the handle 102, and the first box 10 and the second box 20 automatically lock. When the user holds the handle 102 of the first box 10 and lifts the first box 10 from one side, the first box 10 and the second box 20 automatically unlock, and the first box 10 is lifted and separated from the second box 20. This design, through the linkage between the handle 102 and the locking tongue 101, perfectly balances the ease of operation and structural reliability, and is particularly suitable for mobile work scenarios that require frequent reconfiguration of tool combinations.
[0057] Additionally, it should be noted that during the stacking of the first box 10 and the second box 20, another scenario may occur: the handle 102 on the first box 10 is in a retracted state. When stacking toolboxes, some users forget to pull the handle 102 and instead lift the sides of the first box 10 directly. While stacking the first box 10 and the second box 20, because the handle 102 is in a retracted state, the locking tongue 101 on the first box 10 is extended. Since the locking tongue 101 is movably mounted on the locking module 211, and the lock... The bottom of the tongue 101 has an inclined surface. When the first box 10 and the second box 20 are stacked, under the gravity of the first box 10, the locking tongue 101 will be compressed into the locking module 211 when it comes into contact with the second box 20. The locking tongue 101 will correspond to the locking groove 201 when the protrusion 104 at the bottom of the first box 10 matches the recessed groove 202 at the top of the second box 20. At this time, the locking tongue 101 will spring into the locking groove 201 of the second box 20 under the elastic force of the locking tongue spring 215, and the stacked first box 10 and second box 20 will be locked.
