Description

Technical Field

[0001] This utility model belongs to the field of drawer technology, and in particular relates to an anti-tipping drawer storage box. Background Technology

[0002] Currently, plastic storage boxes with drawer structures are widely used in various scenarios such as home storage, office organization, and outdoor activities due to their ease of use and clear categorization.

[0003] However, these storage boxes have some technical drawbacks: to reduce costs and facilitate movement, mainstream products on the market are usually made of low-density plastics (such as PP, ABS, etc.), making the storage box itself relatively lightweight. Furthermore, each drawer acts as an independent storage unit, and when it contains many or heavy items, the drawer itself becomes quite heavy. When the user pulls the drawer out to its maximum extension, the center of gravity of the entire device (the storage box itself plus the pulled-out drawer) shifts significantly forward and downward. At this point, the projection point of the center of gravity easily moves beyond the front fulcrum of the storage box (usually the front casters or the bottom edge of the box), generating a torque that causes the entire storage box to tip forward. Even a slight mishap, such as applying downward pressure or lateral force to the drawer while retrieving or placing items, can easily cause the entire storage box to lose balance and tip forward. This tipping problem not only may cause stored items to scatter and become damaged, but also poses a safety risk of injuring the user. Utility Model Content

[0004] To address the shortcomings of existing technologies, a drawer storage box that can prevent tipping is provided.

[0005] This utility model is achieved using the following technical solution: an anti-tipping drawer storage box, comprising:

[0006] The storage frame has a rectangular box structure and forms a storage cavity with an opening at the front.

[0007] A drawer is slidably disposed within the storage cavity, the drawer including a drawer panel for sealing the front opening and a drawer box connected to the inside of the drawer panel;

[0008] A counterweight is detachably mounted in the storage frame at the far end relative to the front opening. The counterweight is used to set the overall center of gravity of the storage frame.

[0009] By installing a counterweight at the rear of the storage frame, the overall center of gravity distribution of the storage box is effectively altered. When the drawer is fully loaded and pulled out, the anti-tipping moment generated by the counterweight balances the tipping moment caused by the drawer moving forward, ensuring that the center of gravity projection of the entire device remains stable within the support surface. This fundamentally eliminates the risk of tipping forward, protects user safety, and prevents items from scattering and getting damaged. Furthermore, the counterweight is detachable, allowing users to flexibly adjust its weight according to the actual weight of the items stored in the drawer, achieving dynamic balance.

[0010] Preferably, the storage frame has a detachable top cover, and the storage frame has a slot for vertical insertion of the counterweight.

[0011] The above settings allow users to remove the top cover first when installing the counterweight, and then remove the counterweight from the slot, which is quite convenient.

[0012] Preferably, the storage frame is provided with a vertically extending baffle, which is arranged parallel to the rear end wall of the storage frame and forms the slot between the baffle and the rear end wall of the storage frame. The rear end wall of the storage frame protrudes inward and is provided with a vertically extending positioning strip, and the counterweight is provided with a positioning groove that matches the positioning strip.

[0013] By forming a slot between the baffle and the rear wall of the storage frame, the structure can be made more compact. At the same time, by setting a positioning strip on the rear wall of the storage frame and a positioning groove on the counterweight, the counterweight can be limited through the interlocking of the two.

[0014] Preferably, the counterweight is fixed by a fixing plate, which is L-shaped and fits against the top wall and front side wall of the counterweight. The upper and lower ends of the fixing plate are respectively in contact with the upper end of the positioning strip and the bottom of the storage frame. Furthermore, a detachable fixing connection structure is provided between the end of the fixing plate and the positioning strip and the bottom of the storage frame.

[0015] The above method ensures that the counterweight will not move up or down after being fixed by the fixing plate.

[0016] Preferably, the detachable fixed connection structure between the end of the fixing plate and the positioning strip and the bottom of the storage frame includes a connecting block and a screw post. The connecting block is provided with an insertion hole for the screw post to be inserted and a through hole that is coaxial with the insertion hole and passes through the connecting block. After the screw passes through the through hole, it is threadedly engaged with the screw post.

[0017] The above operations facilitate user installation, and the insertion hole positions the screw post, making it easy for the user to screw in the screw.

[0018] Preferably, the counterweight has an L-shaped limiting groove recessed in its wall, and the fixing plate is located in the limiting groove.

[0019] With the above settings, after the fixing plate is fixed, the left and right positions of the counterweight can be limited, so that the counterweight will not sway left and right when the drawer storage box is in use.

[0020] Preferably, the top cover and bottom plate of the storage frame are provided with a mating interlocking structure.

[0021] With the above-described configuration, the interlocking structure can achieve positioning and enhance stability when multiple storage frames are stacked vertically.

[0022] Preferably, a sealing element is provided around the inner periphery of the drawer panel; when the drawer is closed, the sealing element is pressed against the peripheral wall of the front opening of the storage frame to achieve a seal.

[0023] Through the above technical solution, when the drawer is closed, the seal on the inner periphery of the drawer panel and the periphery of the storage frame opening form a compression seal, effectively preventing outdoor rainwater or splashes from seeping into the drawer through the gap between the drawer and the frame, thus achieving active waterproofing. At the same time, this sealing structure also blocks the entry of external humid air, mitigating the problem of items inside the storage cavity becoming damp and moldy due to external moisture penetration, and extending the lifespan of the desiccant. This improves the suitability of the storage box in outdoor or high-humidity environments and the reliability of item preservation.

[0024] Preferably, the storage cavity is provided with slide rails on the opposite side walls, and the drawer is provided with sliders on the two side walls corresponding to the slide rails, which slide in cooperation with the slide rails.

[0025] The above settings facilitate the pulling out of the drawers and prevent them from getting stuck.

[0026] Compared with existing technologies, the beneficial effects of this utility model are as follows: By setting a counterweight at the rear of the storage frame, the overall center of gravity distribution of the storage box is effectively changed. When the drawer is fully loaded and pulled out, the anti-tipping torque generated by the counterweight can balance the tipping torque generated by the drawer moving forward, ensuring that the center of gravity projection of the entire device remains stable within the support surface, fundamentally eliminating the risk of forward tipping, protecting user safety, and preventing items from scattering and getting damaged. At the same time, the counterweight adopts a detachable design, allowing users to flexibly configure the weight of the counterweight according to the actual weight of the items stored in the drawer, achieving dynamic balance.
