Description

Technical Field

[0001] This utility model belongs to the field of box technology, and in particular to a snap-lock connection structure for a stackable toolbox. Background Technology

[0002] CN118418087A discloses a storage box assembly, including a box body and a first module and a second module disposed on opposite sides of the box body. A plurality of boxes can be detachably connected via the first and second modules. The first module includes a locking element, an unlocking element, and a guide portion. The second module includes a mating portion and a receiving portion. The locking element can be locked by applying pressure to the mating portion. The unlocking element is longitudinally slidably installed on the box body, and can be unlocked by applying force to pull the locking element to the mating portion. The guide portion can engage with the receiving portion at a first angle and engage with the receiving portion at a second angle. When the unlocking component is applied to lift the end of the housing to the first angle, the guide part rotates out from the receiving part. The defect of the above technical solution is that: when unlocking, the unlocking component is pushed upward, causing it to slide upward inside the receiving groove. Then, the driving ramp at the bottom of the unlocking component will contact the force rod at the top of the locking component. The force rod will then be subjected to force and rotate along the ramp of the driving ramp, thereby driving the locking component to rotate into the receiving groove along the axis of the rotating shaft. This will disengage the locking component from the slot and unlock it. At this time, the user needs to keep pressing the unlocking button, otherwise the unlocking button and the locking component will reset, resulting in unsmooth unlocking. Utility Model Content

[0003] The purpose of this utility model is to provide a snap-lock connection structure for a stackable toolbox to solve the problems existing in the background technology.

[0004] To solve this technical problem, the technical solution of this utility model is as follows:

[0005] A spring-loaded connection structure for a stackable toolbox includes a box body with a cover hinged to it. Mounting cavities are provided on both sides of the box body. The toolbox also includes a connecting seat with a locking seat hinged to it via a snap-fit ​​pivot. A spring is provided between the connecting seat and the locking seat. A locking hook extends from the bottom end of the locking seat. The connecting seat is fixed within the mounting cavity on the corresponding side. Correspondingly, locking cavities are provided on both ends of the cover, and the locking hook engages within the corresponding locking cavities. A first elastic pin is provided on the inner side of the locking seat, and a first elastic pin locking cavity is provided on the top of the locking cavity. When locked, the first elastic pin is positioned within the first elastic pin locking cavity.

[0006] Preferably, a first guide platform is provided inside the first elastic pin engagement cavity. The first guide platform forms an upwardly curved surface from inside the first elastic pin engagement cavity, and the outer edge of the first curved surface bends downward to form a first smooth transition surface. The provision of the first guide platform makes the engagement and disengagement of the first elastic pin smoother.

[0007] Preferably, the spring is positioned above the buckle pivot.

[0008] During installation, pressing the top of the latching seat disengages the latching hook from the latching cavity, and the first elastic pin pops out from the first elastic pin latching cavity and abuts against the outside of the first elastic pin latching cavity. Even if the latching seat is released, it will not reset and will always remain in the unlocked state. During connection, pressing the bottom of the latching seat causes the first elastic pin and the latching hook to engage with the first elastic pin latching cavity and the latching cavity respectively, thus completing the locking.

[0009] Preferably, connecting posts are provided on the inner walls of both sides of the mounting cavity, and connecting ears are provided on both sides of the connecting seat. After the connecting seat is placed in the mounting cavity, the connecting ears and connecting posts are connected by screws to fix the connecting seat in the mounting cavity.

[0010] The beneficial effects of the above technical solution and this utility model are:

[0011] When this application is used, the design of the elastic pin structure ensures that even if the locking seat is loosened, it will not reset but will always remain in the unlocked state, making it easier to remove the toolbox. Attached Figure Description

[0019] like Figure 1-7 As shown, in order to further explain the technical solution of this utility model, the following detailed description is given through specific embodiments.

[0020] Example 1

[0021] A spring-loaded connection structure for a stackable toolbox includes a box body 1, a cover 2 hinged to the box body, mounting cavities 3 on both sides of the box body, a connecting seat 4, a snap-fit ​​seat 6 hinged to the connecting seat via a snap-fit ​​pivot 5, and a spring 7 between the connecting seat and the snap-fit ​​seat. A snap-fit ​​hook 8 extends from the bottom end of the snap-fit ​​seat. The connecting seat is fixed in the mounting cavity on the corresponding side. Correspondingly, snap-fit ​​cavities 9 are provided on both ends of the cover, and the snap-fit ​​hook snaps into the snap-fit ​​cavities on the corresponding sides. A first elastic pin 10 is provided on the inner side of the snap-fit ​​seat, and a first elastic pin snap-fit ​​cavity 11 is provided on the top of the snap-fit ​​cavity. When locked, the first elastic pin is placed in the first elastic pin snap-fit ​​cavity.

[0022] A first guide platform is provided inside the first elastic pin engagement cavity. The first guide platform forms an upwardly sloping first arc-shaped surface 12 from inside the first elastic pin engagement cavity, and the outer edge of the first arc-shaped surface bends downward to form a first smooth transition surface 13. The first guide platform makes the engagement and disengagement of the first elastic pin smoother.

[0023] The spring is positioned above the buckle shaft.

[0024] During installation, pressing the top of the latching seat disengages the latching hook from the latching cavity, and the first elastic pin pops out from the first elastic pin latching cavity and abuts against the outside of the first elastic pin latching cavity. Even if the latching seat is released, it will not reset and will always remain in the unlocked state. During connection, pressing the bottom of the latching seat causes the first elastic pin and the latching hook to engage with the first elastic pin latching cavity and the latching cavity respectively, thus completing the locking.

[0025] Connecting posts 14 are provided on the inner walls of both sides of the mounting cavity, and connecting ears 15 are provided on both sides of the connecting seat. After the connecting seat is placed in the mounting cavity, the connecting ears and connecting posts are connected by screws to fix the connecting seat in the mounting cavity.
