Technical Field

[0001] This utility model relates to the field of storage box technology, specifically to a sliding lock mechanism for a storage box. Background Technology

[0002] In modern life and work, storage boxes are commonly used tools for organizing and storing items, and are widely used in homes, offices, and industrial fields. For bit boxes that store tools such as bit bits and small parts, they not only need to have good dustproof and moisture-proof performance, but also need to remain stable when stacked to prevent tools from scattering, being lost, or being damaged due to shaking or tipping.

[0003] Currently, most stackable storage boxes on the market only achieve stacking connections through simple slots, protrusions, or other structures, but generally lack a dedicated locking mechanism to secure the stacked boxes. This design means that the boxes rely solely on simple structural fit to maintain their relative positions, lacking effective locking measures.

[0004] Therefore, how to design a storage box structure with a reliable locking mechanism that can achieve stable stacking of boxes has become an urgent problem to be solved in the current storage box technology field. Utility Model Content

[0005] To address the shortcomings in the prior art, this utility model provides a sliding lock mechanism for a storage box.

[0007] The sliding lock mechanism includes a fastening part, an elastic reset part, a locking part, and an elastic switching cover. The locking part is slidably disposed on the box body in a left-right movement manner, and has the following two states as its position changes:

[0008] The locking state achieved between two stacked boxes by connecting with the fastening part, and the unlocking state achieved between the two stacked boxes by separating from the fastening part;

[0009] The elastic reset member provides an unlocking elastic force for the latch to slide from the locked state to the unlocked state.

[0010] The elastic switching cover has an elastic pressing part and a limiting part. The limiting part cooperates with the elastic part on the above-mentioned locking member. By pressing the elastic pressing part, the elastic part is separated from the limiting part to release the limiting effect between the limiting part and the elastic part.

[0011] Release the elastic pressing part to reset the elastic part, and when the elastic part abuts against the limiting part, the locking part is kept in the locked state.

[0012] Furthermore, a groove for installing a sliding lock mechanism is provided on the side of the bottom shell away from the hinge side. A slide rail that slides with the locking element is provided in the groove. The locking element is provided with a handle and a slide groove that slides with the slide rail. The elastic switching cover is detachably connected to the groove. The elastic switching cover is provided with a first clearance groove for the elastic pressing part and a second clearance groove for the handle to extend.

[0013] Furthermore, a spring post is provided on one side of the locking member, and one end of the elastic reset member is sleeved on the spring post, while the other end abuts against the side of the groove.

[0014] Furthermore, the elastic part is provided with a limiting boss that limits the limiting part to each other, a first inclined surface is provided on one side of the limiting boss, and a second inclined surface that matches the first inclined surface is provided on the limiting part.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0038] This utility model provides a sliding lock mechanism for a storage box.

[0039] In this embodiment, refer to Figure 1-8 The sliding lock mechanism of the storage box includes a box body 1 that can be stacked. The box body 1 includes a bottom shell 2 and a box cover 3 that is hinged to the bottom shell 2. It also includes a sliding lock mechanism 5 located on one side of the box body.

[0040] The sliding lock mechanism 5 includes a fastening part 6, an elastic reset part 7, a locking part 8, and an elastic switching cover 9. The locking part 8 is slidably disposed on the box body in a left-right moving manner, and has the following two states as its moving position changes:

[0041] The locking state achieved between two stacked boxes by connecting with the fastening part, and the unlocking state achieved between the two stacked boxes by separating from the fastening part;

[0042] The elastic reset member 7 provides an unlocking elastic force for the latch to slide from the locked state to the unlocked state.

[0043] The elastic switching cover has an elastic pressing part 10 and a limiting part 11. The limiting part 11 cooperates with the elastic part 12 on the above-mentioned locking member. By pressing the elastic pressing part, the elastic part is separated from the limiting part to release the limiting effect between the limiting part and the elastic part.

[0044] Release the elastic pressing part to reset the elastic part, and when the elastic part abuts against the limiting part, the locking part is kept in the locked state.

[0045] In the above technical solution, a sliding lock mechanism is installed on the box body to lock two stacked boxes. In the sliding lock mechanism, the locking element can slide left and right, switching the locked and unlocked states of the boxes by connecting and separating from the latching part; the elastic reset element provides elastic force for unlocking the locking element; the elastic pressing part and the limiting part of the elastic switching cover cooperate to control the locking state of the locking element. This achieves reliable locking of stacked boxes, significantly improving stacking stability, and is especially suitable for bit boxes for storing tools.

[0046] Specifically, a groove 16 for installing a sliding lock mechanism is provided on the side of the bottom shell away from the hinge side. A slide rail 17 that slides with the locking element is provided in the groove 16. The locking element is provided with a handle 18 and a slide groove 19 that slides with the slide rail 17. The elastic switching cover is detachably connected to the groove 16. The elastic switching cover is provided with a first clearance groove 20 for the elastic pressing part and a second clearance groove 21 for the handle to extend.

[0047] In this embodiment, a groove is provided on the side of the bottom shell away from the hinge side to install the sliding lock mechanism. The slide rail in the groove slides and engages with the locking fastener, allowing the locking fastener to slide smoothly and at the same time limiting the sliding trajectory. The locking fastener is provided with a handle for easy operation. The elastic switching cover is detachably connected to the groove. The first clearance groove and the second clearance groove are respectively the elastic pressing part and the handle clearance.

[0048] The above reasonable installation structure design makes the sliding lock mechanism stable to install and easy to disassemble and maintain; the cooperation between the slide rail and the locking fastener ensures the stability and reliability of the sliding of the locking fastener; the design of the handle and the clearance groove makes the operation more convenient for users, improves the user experience, and at the same time ensures the normal functioning of each component of the sliding lock mechanism.

[0049] Specifically, a spring post 22 is provided on one side of the locking member, and one end of the elastic reset member is sleeved on the spring post 22, while the other end abuts against the side of the groove.

[0050] In this embodiment, a spring post is provided on one side of the latch, and one end of the elastic reset member is fitted onto the spring post, while the other end abuts against the side of the groove. When the latch is in the locked state, the elastic reset member is compressed and accumulates elastic potential energy. After the elastic switching cover is pressed to release the limit, the elastic reset member releases the elastic potential energy, pushing the latch to slide towards the unlocked state. The cooperation between the spring post and the elastic reset member provides a stable and reliable elastic force for unlocking the latch, enabling the latch to automatically switch from the locked state to the unlocked state. This simplifies the unlocking operation process and improves the convenience and reliability of unlocking, eliminating the need for the user to manually apply continuous force to unlock the latch.

[0051] Specifically, the elastic part is provided with a limiting boss 24 that limits the limiting part to each other, a first inclined surface 25 is provided on one side of the limiting boss 24, and a second inclined surface 26 that is adapted to the first inclined surface is provided on the limiting part.

[0052] In this embodiment, the limiting boss of the elastic part cooperates with the limiting part to limit the locking element. When sliding from the unlocked state to the locked state, the first and second inclined surfaces guide the movement, reducing the resistance between the limiting boss and the limiting part, making the return to the original position smoother and less strenuous.

[0053] Specifically, the groove has connecting grooves 27 on both sides, the elastic switching cover has elastic plates 28 on both sides, and the elastic plates 28 have connecting steps 29 that connect with the connecting grooves.

[0054] In this embodiment, the connecting grooves on both sides of the groove cooperate with the connecting steps on the elastic plates on both sides of the elastic switching cover. Through the elastic deformation of the elastic plates, the elastic switching cover and the groove are detachably connected, which facilitates the installation and disassembly of the elastic switching cover.

[0055] Specifically, the elastic pressing part is provided with a pressing indicator mark 30, and the surface of the elastic switching cover is provided with a locking direction mark 31.

[0056] In this embodiment, the pressing indicator on the elastic pressing part provides the user with clear guidance on the pressing position, while the locking direction indicator on the surface of the elastic switching cover prompts the user on the locking direction of the fastener, enabling the user to perform locking and unlocking operations more accurately and quickly.

[0057] Specifically, a fastening groove 32 is provided on the side of the bottom shell away from the hinge side. A lid fastening member 33 is rotatably connected in the fastening groove 32. The groove is located in the fastening groove below the lid fastening member. The locking member extends downwards from the bottom shell to provide a locking leg 34. The fastening part is located on the surface of the lid away from the hinge side, and a locking step 35 is provided on the fastening part to connect with the locking leg 34.

[0058] In this embodiment, the lid fastener is rotatably connected to the fastening groove of the bottom shell, and the locking leg of the locking fastener extending downwards to the bottom shell is connected to the locking step of the lid fastener, thereby realizing the locking of the box body by the sliding lock mechanism.

[0059] Since the grooves and the components within them (such as elastic reset parts, locking parts, and elastic switching covers) are located directly within the original box's locking groove, the design of these structures will not change the original shape of the box or increase its volume. Moreover, the internal space of the box is not easily encroached upon by the aforementioned active areas and components set or formed on the side walls, ensuring the flatness of the inner wall of the box and effectively ensuring that the internal space of the box is not affected.

[0060] Specifically, the hook is located on the bottom shell surface near the hinge side, and the hooked part is located on the lid surface near the hinge side.

[0061] In this embodiment, the hook is located on the bottom shell near the hinge side, and the hooked part is located on the lid near the hinge side. When the two storage boxes are stacked one on top of the other, the hook and the hooked part of the bottom shell of the upper storage box are hooked together with the groove of the hooked part of the lid of the lower storage box to achieve the connection of the hook-lock mechanism. Together with the sliding lock mechanism, the stacked boxes are locked.

[0062] Specifically, the four corner surfaces of the bottom shell are provided with protrusions 36, the protrusions 36 are provided with alignment grooves 37, and the four corner surfaces of the lid are provided with alignment steps 38 that align with the protrusions.

[0063] In this embodiment, the protrusions and alignment grooves at the four corners of the bottom shell cooperate with the alignment steps at the four corners of the lid. When the storage boxes are stacked, the precise cooperation between the protrusions and the alignment steps (the two use their mating sides for limiting) enables the storage boxes to be quickly and accurately stacked and positioned, ensuring that the sliding lock mechanism and the hook lock mechanism can be accurately connected.

[0064] Specifically, a hook-lock mechanism is provided on the box body on the side away from the sliding lock mechanism. The hook-lock mechanism includes a hook part 13 and a hooked part 14. The hooked part 14 is provided with a groove 15 for hooking with the hook part.

[0065] In this embodiment, by providing a hook-locking mechanism on the other side of the box, the connection stability between the stacked boxes is further improved.

[0066] The method of using the slide lock mechanism is as follows:

[0067] The sliding lock mechanism can be used for locking and unlocking operations.

[0068] Lock-off operation:

[0069] S1. Stack the two storage boxes one on top of the other, and make the protrusion at the corner of the bottom shell of the upper storage box fit and limit the step at the corner of the lid of the lower storage box to achieve stacking of the storage boxes.

[0070] S2. Push the locking fastener of the sliding lock mechanism so that the locking foot of the fastener connects with the locking step of the upper storage box lid fastening part, thereby locking the two boxes by the sliding lock mechanism. At the same time, hook the hook part of the upper storage box bottom shell near the hinge side and hook the groove of the hooked part of the lower storage box lid near the hinge side to complete the connection of the hook lock mechanism.

[0071] Unlocking procedure:

[0072] S1. Press the pressing indicator area of ​​the elastic pressing part. Pressing the elastic pressing part acts on the elastic part, causing the elastic part to deform and break away from the limitation of the limiting part. Under the elastic force of the elastic reset part, the locking part slides to the unlocked side, thereby separating the locking leg from the locking step of the upper storage box cover fastening part.

[0073] During locking, the storage boxes are first positioned by the protrusions and alignment steps. Then, the locking mechanism is pushed to connect the locking legs with the locking steps, hooking the hook and the hooked part to complete double-sided locking. During unlocking, pressing the elastic pressing part disengages the elastic part from its limit position. Under the action of the elastic reset part, the locking mechanism slides automatically to unlock. This method fully utilizes the functional advantages of the sliding lock mechanism and the hook lock mechanism, achieving fast and stable locking and convenient and reliable unlocking of the storage boxes. It meets the user's needs for using storage boxes in different scenarios, improving the practicality and versatility of the storage boxes.

[0074] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
