Description

Technical Field

[0001] This application relates to the field of storage boxes, and in particular to a storage box that can achieve storage limit and limit adjustment. Background Technology

[0002] In existing technologies, storage boxes for books and loose desktop items have been widely developed and applied to solve the problem of clutter in item storage. These existing storage boxes typically employ a basic box structure with fixed partitions or simple adjustable dividers inside, such as sliding groove designs or snap-on partitions, to divide the space into multiple areas, thereby achieving the classification and placement of items such as books, stationery, and documents. However, most designs focus on simple classification and lack fine-tuning functions. For example, while some storage boxes allow for partition position adjustment, the adjustment process often requires manually removing or repositioning the partitions, or even relying on external tools such as screwdrivers, making the operation relatively cumbersome. Furthermore, these devices often employ a linkage mechanism, meaning that adjusting one side's limit will affect the other side or other parts, preventing users from independently controlling the positions of both sides' limit positions.

[0003] While existing technologies offer some storage benefits, significant shortcomings remain due to design limitations. Specifically, fixed-partition storage boxes cannot adapt to changes in item size. For example, when books vary in thickness or small miscellaneous items are added, users cannot flexibly adjust the limiting positions, resulting in low space utilization or items shifting within the box, hindering neat storage. Adjustable devices, on the other hand, suffer from complex adjustment mechanisms or reliance on a unified linkage structure, making operation time-consuming and error-prone, often requiring multiple attempts to achieve the desired effect. Furthermore, the interdependence of the limiting devices on both sides further limits adjustment flexibility; users cannot independently fine-tune one side without affecting the other, which is particularly inconvenient when dealing with asymmetrical items such as books of varying thicknesses. Utility Model Content

[0004] The purpose of this application is to overcome at least one deficiency of the existing technology and provide a storage box with a storage limiting function and an independently adjustable limiting position, which aims to improve the flexibility of storage, space utilization efficiency and ease of operation.

[0005] To achieve the above objectives, this application discloses a storage box, which includes a box body with an open accommodating cavity, consisting of a base plate, a rear side plate connected to the periphery of the base plate, a front side plate, and a pair of side plates, as well as an adjustable limiting mechanism disposed on the box body; wherein, the rear side plate is higher than the front side plate, forming a stepped structure with a lower front and a higher rear to improve the convenience of taking out and putting in.

[0006] The upper edges of the front and rear side panels extend horizontally outward to form parallel strip-shaped mounting walls, and each mounting wall has a continuously extending straight guide groove along its length.

[0007] Two adjustable limiting mechanisms are respectively assembled on the corresponding mounting wall. The adjustable limiting mechanism includes a sliding base and a limiting baffle. The sliding base is provided with a guide part that cooperates with the linear guide groove, so that it can move axially along the guide groove.

[0008] The limiting baffle is pivotally hinged to the top of the sliding base and can rotate about the horizontal axis.

[0009] On the surface of the sliding base facing the corresponding front or rear side plate, there is at least one protruding or recessed limiting structure. Correspondingly, the outer surfaces of the front and rear side plates are axially distributed with continuously arranged locking tooth structures. The locking tooth structures, in conjunction with the limiting structures, achieve upper limit constraint on the sliding base in the sliding direction.

[0010] Furthermore, symmetrical grip openings are provided on the upper part of both side panels to facilitate handling.

[0011] Furthermore, the mounting wall is provided with guide ridges parallel to the extension direction of the straight guide groove on both sides of the width direction of the straight guide groove. Correspondingly, the sliding base is provided with a secondary sliding groove that matches the profile of the two guide ridges, and the secondary sliding groove forms a directional sliding pair with the guide ridges. Through the double-sided coupling effect of the double guide ridges and the secondary sliding groove, the local structural rigidity of the mounting wall is enhanced, and the elastic deformation of the straight guide groove caused by force is suppressed, thereby preventing the sliding base from getting stuck or derailing.

[0012] Furthermore, the sliding base includes a T-shaped slider and a U-shaped kit that engages with the slider;

[0013] Furthermore, a vertical plate is erected on the surface of the limiting baffle to improve the structural strength of the limiting baffle.

[0014] Furthermore, anti-slip silicone pads are glued to the four corners of the bottom surface of the base plate.

[0015] Furthermore, the grip opening is a waist-shaped through hole with chamfered edges or soft covering, which improves grip comfort and prevents cuts.

[0016] Based on the above structure, when an axial thrust is applied to the adjustable limiting mechanism, at least one of the sliding base or the locking tooth structure undergoes elastic deformation, causing the locking structure to disengage from its current limiting position and slide along the locking tooth structure. Upon reaching the target position, the external force is removed, and the elastic deformation recovers, causing the locking recess and locking tooth structure to reset, achieving reliable positioning within a lateral force range below the critical value of the component's elastic deformation. The limiting baffle can rotate upwards around the pivot axis to a retractable position, avoiding interference with the accommodating cavity space; when rotated downwards to the working position, it forms an object limiting interface perpendicular to the base plate.

[0017] Compared with existing technologies, this technical solution achieves tool-free, high-precision independent limit adjustment through the synergistic effect of an adjustable limit mechanism and a hinged limit baffle, while ensuring the mechanical reliability of the adjustment process and the space release capability in the idle state.

[0018] The beneficial effects listed above are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation methods will be further disclosed in the embodiments or other descriptive sections of this application. Attached Figure Description

[0031] See attached document Figures 1 to 7 This embodiment discloses an adjustable limiting storage box to solve the problems of fixed internal dimensions, easy tipping of items, and inconvenience in retrieval of traditional storage containers. The storage box includes a box body 1 with an open receiving cavity, consisting of a base plate 2, a rear side plate 3 connected to the periphery of the base plate 2, a front side plate 4, and a pair of side plates 5, and two adjustable limiting mechanisms 8 disposed on the box body 1. The height of the rear side plate 3 is greater than the height of the front side plate 4, forming a stepped structure with a lower front and higher rear to improve the convenience of retrieving and placing items. The upper edges of the front side plate 4 and the rear side plate 3 are respectively... Parallel strip-shaped mounting walls 6 extend outwards horizontally, and each mounting wall 6 has a continuously extending linear guide groove 7 along its length direction; each adjustable limiting mechanism 8 includes a sliding base 801 and a limiting baffle 802. The sliding base 801 is equipped with a guide part that cooperates with the linear guide groove 7, so that the sliding base 801 can move along the axial direction of the linear guide groove 7; the limiting baffle 802 is pivotally hinged to the top of the sliding base 801 and can rotate about the horizontal axis. Overall, these components achieve the coordinated operation of the adjustable limiting function through mechanical coupling.

[0032] Furthermore, the sliding base 801 has at least one protruding or recessed limiting structure on the surface facing the corresponding outer surface of the front side plate 4 or the rear side plate 3. Conversely, the outer surfaces of the front side plate 4 and the rear side plate 3 have continuously arranged locking tooth structures distributed axially. This locking tooth structure, in conjunction with the limiting structure, can constrain the position of the sliding base 801 in the sliding direction. This tooth constraint design provides a progressively adjustable mechanical locking capability. Based on this, when an axial thrust is applied to the adjustable limiting mechanism 8, at least one of the sliding base 801 or the locking tooth structure undergoes elastic deformation, causing the limiting structure to disengage from its current constrained position and slide along the locking tooth structure. After reaching the target position, the external force is removed, and the elastic deformation recovers, causing the limiting structure and the locking tooth structure to reset. This achieves reliable positioning within a lateral force range below the critical value of the component's elastic deformation, ensuring resistance to accidental displacement during the adjustment process. Subsequently, the limiting baffle 802 can rotate upward around the pivot to a storage position to reduce the space occupied by the receiving cavity. This hinged arrangement is used to optimize the space utilization in the idle state.

[0033] Furthermore, the upper part of the two side plates 5 is symmetrically provided with grip openings 9 to facilitate the handling of the storage container. The grip openings 9 are preferably waist-shaped through holes, and the waist-shaped contour provides an ergonomic grip experience. Preferably, the edges of the grip openings 9 are chamfered or covered with a soft layer to avoid cutting hands and improve grip comfort.

[0034] Based on this, guide strips 701 are provided on both sides of the straight guide groove 7 in the width direction, and the extension direction of the guide strips 701 is coaxial and parallel to the straight guide groove 7. Correspondingly, the sliding base 801 is provided with a guide groove 802 that matches the profile of the guide strips 701, and the guide grooves 802 and the guide strips 701 form a directional sliding pair. This mating structure allows the sliding base 801 to simultaneously apply normal constraints to the straight guide groove 7 in the groove width direction, thereby improving the structural rigidity of the straight guide groove 7.

[0035] The strengthening mechanism of the sliding base 801 for the linear guide groove 7 is specifically manifested as follows: the guide groove 802 and the guide strip 701 form a constraint interface with clearance fit in the groove width direction. The constraint reaction force generated by this interface directly restricts the lateral elastic deformation of the linear guide groove 7. The characteristic of the guide strip 701 extending continuously along the length of the groove body makes it and the guide groove 802 together form a distributed support system, which significantly enhances the groove body's ability to resist bending and torsional deformation.

[0036] The constraint principle of the above structure is that when the linear guide groove 7 is subjected to lateral load, the mating interface between the guide strip 701 and the guide groove 802 diverts the load to the sliding base 801, reducing stress concentration in the groove itself. This design increases the stiffness in the groove width direction to more than twice that of an unconstrained structure, effectively suppressing the deformation of the groove opening and ensuring the smoothness of the sliding pair's movement and its anti-derailment performance.

[0037] Preferably, the sliding base 801 includes a T-shaped slider 8011 and a U-shaped fitting 8012 that engages with the slider 8011. This split design facilitates manufacturing and assembly. Preferably, a vertical plate is provided on the surface of the limiting baffle 802 to enhance the overall structural strength of the limiting baffle 802. Finally, anti-slip silicone pads are bonded to the four corners of the lower surface of the base plate 2. These anti-slip silicone pads are a known component in the prior art and are used to increase placement stability. It can be understood that the above components work together to achieve tool-free position adjustment, high-precision positioning, and space release capability in the idle state of the adjustable limiting mechanism 8, while enhancing the mechanical reliability of the adjustment through an elastic deformation mechanism.

[0038] Based on the above, when this storage container is used for book storage, the two adjustable limiting mechanisms 8 can slide independently along the straight guide groove 7 to adapt to the positioning needs of books of different widths. Specifically, when the books are placed upright on the base plate 2, the operator can push the sliding bases 801 on both sides respectively, so that the limiting baffles 802 precisely abut against the sides of the books to form a customized storage space. In particular, when the number of books stored is small, resulting in a reduction in the support surface of the book column, the position of the sliding bases 801 is adjusted so that the limiting baffles 802 are close to the spine of the outermost book. At this time, the limiting baffles 802 form a rigid blocking interface perpendicular to the base plate 2, and its upright structure provides sufficient bending stiffness to resist the tendency of the books to tip over. This anti-tipping function relies on the meshing locking mechanism of the locking tooth structure and the limiting structure. When the lateral force is lower than the elastic deformation critical value, the limiting baffles 802 will not shift, thereby maintaining the vertical stability of the book column.

[0039] Preferably, the elastic deformation engagement mechanism of the locking tooth structure and the limiting structure allows for micron-level stroke adjustment precision, ensuring that books are tightly arranged and the covers are not squeezed or deformed. At the same time, if it is necessary to store thin books or notebooks that are lower than the limiting baffle 802, either limiting baffle 802 can be rotated upwards to a stored position, thereby avoiding obstruction of the top label of the book.

[0040] Furthermore, in scenarios involving storage of miscellaneous items of varying heights, the adjustable limiting mechanism 8 demonstrates flexibility through independent control: on one hand, the limiting baffle 802 can be rotated to a working position, and the positions of the sliding bases 801 on both sides can be adjusted synchronously to match the maximum width of regular items, forming a stable vertical limiting boundary; on the other hand, when miscellaneous items have irregular protrusions, one side of the limiting baffle 802 can be selectively folded up for storage, while the other side of the limiting baffle 802 remains in its working state to provide local support. Understandably, through the reversible locking cooperation between the sliding base 801 and the locking tooth structure, both books and miscellaneous items can maintain their limiting state after a single adjustment, and can be quickly repositioned without tools when a change in layout is needed.

For component installation processes, basic material mechanical parameters, or general standard parts not described in detail, they all fall within the scope of existing technology that can be directly implemented or conventionally selected by those skilled in the art based on known technologies.
