Description

Technical Field

[0001] This article belongs to the technical field of stackable boxes, specifically relating to a pull-out quick-release stackable toolbox. Background Technology

[0002] Tool boxes are the main storage containers for hardware tools. Because hardware tools come in a wide variety of sizes and types, they need to be organized and placed in different categorized tool boxes.

[0003] To facilitate transportation and storage, more and more toolboxes on the market are becoming stackable. However, the current combination stackable toolboxes on the market have the problem of cumbersome stacking and disassembly steps, requiring at least two or more steps, which is cumbersome for people and prolongs the operation time.

[0004] Existing technology CN207029864U discloses a multi-layer bit storage box, comprising several stacked boxes arranged from top to bottom. Each stacked box has a locking mechanism on its side, and each lower stacked box (except the topmost one) has a snap-lock mechanism on its side. Between every two adjacent stacked boxes, the snap-lock mechanism of the lower stacked box engages with the locking mechanism of the upper stacked box. The advantages of this invention are: by setting up multiple storage boxes, the storage capacity is expanded while reducing storage space, thus allowing for the storage of more bits; by setting the locking mechanisms and snap-lock mechanisms, the storage boxes can be combined and disassembled, making bit organization more convenient; and by setting slots and inserts, the connection between the storage boxes is made more secure.

[0005] However, in the aforementioned existing technology, it is still necessary to manually lock the side clips after the toolboxes are stacked. Although this stacking and fixing method has greatly simplified the cumbersome fixing process, it still adds two manual fixing steps in the actual stacking of the toolboxes. Summary of the Invention

[0006] This paper proposes a pull-out quick-release stackable toolbox, characterized by its stacked configuration, with the bottom of the upper box connected to the top of the lower box. The toolbox includes a top shell and a bottom shell connected by snap-fit ​​fasteners. The top shell has hooks on both sides of its upper surface, and the bottom of one side of the bottom shell has a movable groove. The other side of the bottom shell has a hook. The movable groove contains a hook and a quick-release handle. The hook is located on the bottom surface of the groove, and the handle is located on the outside of the hook. The movable hooks on the bottom of the upper box and the bottom shell hooks connect to the top shell hooks on the top of the lower box. This allows toolboxes that originally required multiple steps to be stacked and fixed to be quickly disassembled through the cooperation of the fixed and movable hooks. The movable hooks can be quickly disassembled simply by pulling on one side of the toolbox. It is simple, efficient and convenient. Installation is also achieved by simply tilting and pressing down. This enables quick fixing and disassembly of stacked toolboxes, thereby improving the ease of use of the toolboxes. It is very quick and easy, and stacking can be completed in one step, which greatly simplifies the process of making toolboxes.

[0007] The top shell hook has a C-shaped cross-section and is long and narrow. The hook groove of the top shell hook faces the longitudinal centerline of the top shell. The top shell hook is connected to the bottom shell hook and the movable hook. They are connected and fixed to each other through the connecting device on the bottom shell. The mirror setting also eliminates the need to confirm the front and back orientation of the toolbox during installation, allowing for one-step installation.

[0008] The movable slot is rectangular in shape. The bottom surface of the movable slot has a bottom shell hook spring hole. Both front sides of the movable slot have bottom shell handle spring slots. Both rear sides of the movable slot have vertical limiting slots. The top surface of the movable slot has symmetrical handle limiting holes. The movable slot on one side of the bottom shell is used to install the movable hook and quick-release handle. Through the cooperation of the internal limiting and spring, the movable hook and quick-release handle can be limited to a fixed direction of movement within the movable slot.

[0009] The bottom shell hook has the same shape as the top shell hook, the hook groove of the bottom shell hook faces the outside of the bottom shell, and the position of the bottom shell hook is mirror image of the position of the top shell hook.

[0010] The quick-release handle is C-shaped. Vertically protruding handle spring grooves are located on the rear sides of both sides of the quick-release handle. Handle limiting blocks are located on the lower front sides of both sides of the quick-release handle. A handle grip edge is located on the outer side of the bottom surface of the quick-release handle, and an oblique handle push surface groove is located on the inner side of the bottom surface of the quick-release handle. Vertical limiting guide plates are located on the top of both sides of the quick-release handle. The handle spring grooves are connected to the handle spring grooves on the bottom shell. The handle limiting blocks are located inside the vertical limiting grooves, and the limiting guide plates are located inside the handle limiting holes. The quick-release handle allows for vertical movement within the movable slot while simultaneously driving the movable hook to move horizontally. Furthermore, the various limiting blocks and guide plates on the quick-release handle ensure stable movement within the movable slot.

[0011] The movable hook is rectangular in shape, with a movable hook head at the bottom and a protruding, angled hook push surface on the front. A groove protrusion is vertically oriented downwards in the center of the hook push surface, and an embedded hook spring hole is located in the center of the groove protrusion. The hook push surface and groove protrusion are connected to the handle push surface groove. The hook spring hole is aligned with the center of the hook spring hole on the bottom shell. The movable hook, located inside the movable recess, can automatically move left and right with the quick-release handle. A gap exists between the movable hook and the bottom surface of the movable recess, allowing the movable hook to move to the left by a pressing motion. Therefore, installation only requires a tilted, direct downward press.

[0012] The bottom shell hook spring hole is a circular embedded cylindrical tube. A movable hook spring is installed inside the bottom shell hook spring hole. The bottom shell hook spring hole is connected to the hook spring hole through the movable hook spring. The hook spring hole is located in the groove on the back of the movable hook. Two cylindrical tubes are concentrically arranged in the hook spring hole, and the movable hook spring is located between the two cylindrical tubes. The outer diameter of the cylindrical tube at the center of the hook spring hole is smaller than the inner diameter of the bottom shell hook spring hole, and the inner diameter of the cylindrical tube around the hook spring hole is larger than the outer diameter of the bottom shell hook spring hole. The movable hook spring enables the movable hook to automatically push out to the right, so that the movable hook can automatically, conveniently and quickly return to the correct position and fix itself.

[0013] The bottom handle spring groove is rectangular in shape, with a through bottom. The width of the bottom handle spring groove is greater than the outer width of the handle spring groove. The handle spring groove is a vertical rectangular block with a circular spring placement groove vertically located in the middle. A quick-release handle spring is installed inside the spring placement groove. One end of the quick-release handle spring is connected to the bottom of the spring placement groove, and the other end is connected to the top surface of the bottom handle spring groove. The quick-release handle spring enables the quick-release handle to automatically return to its original position downwards, thus allowing the quick-release handle to avoid the return of the movable hook and ensuring that the movable hook can be automatically fixed.

[0014] The vertical limiting groove is rectangular in shape, and a limiting horizontal baffle is provided at the bottom of the vertical limiting groove. The width inside the vertical limiting groove is greater than the width of the handle limiting block. The handle limiting block is right-angled triangular in shape. One right-angled side of the handle limiting block is connected to the quick-release handle, and the other right-angled side of the handle limiting block is parallel to the limiting horizontal baffle, which restricts the downward displacement of the quick-release handle and prevents the quick-release handle from coming off downward.

[0015] Both the handle push surface groove and the hook push surface are sloping surfaces with the left side higher than the right side. The handle push surface groove is T-shaped. The vertical groove of the handle push surface groove has sloping edges on both sides of the middle. The vertical groove of the handle push surface groove is connected to the groove protrusion. The horizontal groove of the handle push surface groove is connected to the hook push surface. The groove protrusion has sloping edges on both sides. The sloping edges of the groove protrusion are connected to the sloping edges of the handle push surface groove. The inclined push surface converts the vertical displacement of the quick-release handle into the horizontal displacement of the movable hook, thus realizing the hook-lift quick-release method. Beneficial effects

[0016] The toolbox, which originally required multiple steps to stack and secure, can now be quickly disassembled using a combination of fixed and movable hooks. Simply pull on one side of the toolbox to release the movable hook – simple, efficient, and convenient. Installation is also straightforward, requiring only a tilted downward press. This allows for rapid fixing and disassembly of stacked toolboxes, significantly improving their usability and simplifying the stacking process.

[0017] The top shell and the bottom shell are connected and fixed together by a hook. The mirror setting also eliminates the need to confirm the front and back orientation of the toolbox during installation, allowing for a one-step installation.

[0018] The movable slot on one side of the bottom shell is used to install the movable hook and quick-release handle. Through the cooperation of internal limit and spring, the movable hook and quick-release handle can be limited to move in a fixed direction within the movable slot.

[0019] The quick-release handle allows for vertical movement within the movable slot, while also enabling horizontal movement of the movable hook. Furthermore, various limit blocks and guide plates on the quick-release handle ensure stable movement within the movable slot.

[0020] The movable hook is located inside the movable groove and can automatically move left and right with the quick-release handle. There is a gap between the movable hook and the bottom surface of the movable groove, so that the movable hook can be pushed to the left. Therefore, installation can be achieved by simply tilting and pressing down.

[0021] The movable hook spring automatically pushes it out to the right, allowing it to automatically and quickly return to its original position. The quick-release handle spring automatically returns the quick-release handle downward, preventing it from moving away from the movable hook and ensuring it stays in place. This also limits the downward movement of the quick-release handle and prevents it from coming off.

[0022] The inclined push surface converts the vertical movement of the quick-release handle into the horizontal movement of the movable hook, thus enabling the hook-lift quick-release method. Attached Figure Description

[0037] Implementation example;

[0038] Before use, the top shell 1 and bottom shell 2 are fixed together with snaps to form a closed toolbox. When preparing to install the toolbox, first tilt the bottom shell hook 5 and connect it to the top shell hook 11 on one side. Then, directly press down with the bottom shell hook 5 as the base point. At this time, the movable hook 4 will be displaced because it touches the top shell hook 11. Because the movable hook 4 is restricted by the quick-connect handle and the movable slot, the movable hook 4 can only resist the force of the movable hook spring 45 and move to the left. When the toolbox is completely pressed down and stacked, the movable hook 4 will be automatically pushed to the right by the movable hook spring 45 because the movable hook head 41 has no restriction, thus completing the automatic fixing of the movable hook 4.

[0039] When the stacked toolboxes need to be separated, simply pull the quick-release handle 3 upwards. At this time, the quick-release handle 3 will move upwards, and the handle push surface groove 33 will also push the hook push surface at an angle. The hook push surface drives the movable hook 4 to resist the left displacement of the movable hook spring 45. At this time, the movable hook head 41 separates from the top shell hook 11, and the upper toolbox will also be lifted and turned with the bottom shell hook 5 as the reference. Then the toolbox can be taken out directly. When the quick-release handle 3 is released, the quick-release handle 3 and the movable hook 4 will be automatically returned to the correct position by the quick-release handle spring 36 and the movable hook spring 45.
