Description

Technical Field

[0001] This utility model relates to the field of storage structure technology, specifically an adjustable multi-functional storage rack structure. Background Technology

[0002] Wardrobes and cabinets are common storage spaces in home furnishings, but traditional wardrobes use fixed shelves that cannot be dynamically adjusted according to the size of the items stored (such as the height difference between heavy winter clothes and light summer clothes). This results in low space utilization and a common phenomenon of "wasted upper space and piled-up bottom items." Existing shelf systems are difficult to integrate with new storage containers (such as vacuum compression bags and drawer-style storage boxes), and size mismatches can easily occur when users introduce third-party storage accessories, creating dead corners in the space.

[0003] Most mainstream telescopic storage racks on the market adopt a one-way adjustment design, which cannot achieve three-dimensional spatial adaptation. Moreover, the traditional buckle design is troublesome to adjust and has limited load-bearing capacity. In addition, there is a method of fixing with screws, but the actual friction is insufficient and it is easy to shift. Using hollow metal tubes will cause the tube to deform, which is a destructive adjustment and not conducive to long-term use. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable multi-functional storage rack structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable multi-functional shelving structure, comprising a panel containing multiple shelves and two side frames as supports, with a support rod for supporting the shelves between the two side frames, and the panel being placed on the support rod;

[0006] A single side frame includes at least one crossbar, two sets of interlocking vertical rods I and II, wherein vertical rod I is provided with a movable plunger, and vertical rod II is provided with multiple positioning grooves; when the plunger is engaged with the positioning groove, vertical rod I and vertical rod II cannot retract, but they can be stretched but not retracted, that is, they can maintain height when carrying items.

[0007] Preferably, one side of the positioning groove is provided with a wedge-shaped surface, which pushes the plunger to move, allowing the vertical rod I and vertical rod II to extend. That is, the height of the shelf can be adjusted without operating the plunger, which is convenient and quick.

[0008] Preferably, a limiting block is fixedly provided on the vertical rod I, the plunger is slidably inserted with the limiting block, and a spring is provided between the plunger and the limiting block to ensure stability when carrying items.

[0009] Preferably, the ends of the vertical rods I and II that are far apart from each other are provided with plugs, and the two ends of the horizontal frame are provided with plug slots that match the plugs. The depth of the plug slots is greater than or equal to twice the height of the plugs, which enables multiple shelves to be stacked in the height direction.

[0010] Preferably, the crossbar includes one crossbar I and two crossbars II, the crossbars II being slidably connected to the crossbar I, and the two crossbars II being located at both ends of the crossbar I to achieve width adjustment.

[0011] Preferably, the support rod includes an outer tube and an inner tube that are inserted into each other, for adjusting the length.

[0012] Preferably, the panel further includes a positioning plate, which is provided with fixing holes, clips and clamping blocks;

[0013] Multiple support rods are provided. At least one of the support rods has its outer sleeve inserted into the fixing hole at one end near the inner tube. The clamping piece is squeezed by the clamping block and makes contact with the inner tube, thereby achieving fixation after length adjustment.

[0014] Preferably, the panel also includes a variable-size adjustment plate to adapt to the internal dimensions of the cabinet as much as possible and reduce gaps.

[0015] Compared with the prior art, the beneficial effects of this utility model are: this utility model can be adjusted in three directions: length, height and width. When adjusting the height, it can be raised by simply pulling. After releasing, it can be automatically locked and fixed at the height by pressing down with gravity. Moreover, this structure is more stable and has higher load-bearing capacity than the traditional screw pressing or friction fixing method. In addition, this application also proposes a structure for quick fixing and loosening in the length direction. Furthermore, an adjustment plate that can adjust the size is added to meet the actual application size as much as possible and reduce gaps. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Please see Figure 1-13 This utility model provides a technical solution: an adjustable multi-functional storage rack structure, including a panel containing multiple storage boards 1 and two side frames as support, with a support rod 5 for supporting the storage boards 1 between the two side frames, and the two ends of the support rod 5 being inserted into the side frames. The area of ​​the panel can be changed by increasing the number of storage boards 1.

[0032] A single side frame includes at least one horizontal frame 2, two sets of interlocking vertical bars I3 and II4.

[0033] The vertical rod I3 is provided with a movable plunger 301, and the vertical rod II4 is provided with multiple positioning grooves 401. When the plunger 301 is engaged with the positioning grooves 401, the vertical rod I3 and the vertical rod II4 cannot retract. Due to the influence of gravity, the vertical rod I3 and the vertical rod II4 cannot extend on their own. Therefore, the height can be determined by preventing them from retracting on their own.

[0034] Specifically, when leaving the factory, vertical rods I3 and II4 are usually positioned at maximum overlap for easy transportation and packaging. This position is also the most convenient for users to place in wardrobes or cabinets during initial use. Therefore, stretching is the most common operation when adjusting.

[0035] To facilitate adjustment operations, such as Figure 4 As shown, a wedge-shaped surface 402 is provided on one side of the positioning groove 401. The wedge-shaped surface 402 pushes the plunger 301 to move, allowing the vertical rod I3 and the vertical rod II4 to extend, as shown. Figure 3 and 6 As shown, a limit block 302 is fixedly installed on the vertical rod I3 (fixed by screws or adhesive), the plunger 301 is slidably inserted into the limit block 302, and a spring 303 is provided between the plunger 301 and the limit block 302.

[0036] In practical use, due to the elastic force of spring 303, the right end of plunger 301 (such as...) Figure 4 The direction) is in close contact with the side of the positioning groove 401. In this way, the upper side of the plunger 301 and the lower side of the positioning groove 401 are engaged (at this time, the upper side of the plunger 301 is also engaged with the inner side of the limiting block 302) to achieve engagement, so that the vertical rod II4 cannot move downward relative to the vertical rod I3 even when it is pressed.

[0037] When it is necessary to raise the height, simply pull down the vertical rod I3 (or pull up the vertical rod II4). At this time, the plunger 301 will retract along the wedge surface 402 and overcome the elastic force of the spring 303 to the inside of the limit block 302. When the moving distance exceeds the size of the wedge surface 402, it will automatically reset and engage. It can also automatically fix itself after each pull to prevent the adjustment distance from being too large and difficult to control.

[0038] When retraction is required, manually pull the plunger 301 outward to retract the vertical rod I3 and vertical rod II4.

[0039] The cross-sections and three-dimensional disassembly diagrams of vertical rods I3 and II4 are as follows: Figure 6 and 10As shown, it is also equipped with reinforcing ribs. The structure of this application is applied to common wardrobes according to the proportions shown in the schematic diagram (using conventional polymer materials such as PP), and has been tested to bear a weight of more than 40kg.

[0040] To enable multiple devices to be used simultaneously, and to ensure a certain level of connection stability between them, such as... Figure 4 and 10 As shown, the ends of the vertical rods I3 and II4 that are far apart from each other are provided with connectors 6, and the two ends of the crossbar 2 are provided with insertion slots 7 that match the connectors 6. The depth of the insertion slots 7 is greater than or equal to twice the height of the connectors 6, that is, the vertical rods I3 and II4 of different heights on the same crossbar 2 can be jointly inserted. In this way, the amount of material used can be reduced while ensuring stability. If two layers are used, only three crossbars 2 are needed.

[0041] Specifically, in order to achieve length adjustment (which, depending on the actual situation, can also be considered as the width of the cabinet space), the support rod 5 includes an outer sleeve 501 and an inner sleeve 502 that are interlocked, meaning the two are plugged together, and the length is adjusted by plugging and unplugging; and the bottom of the carrying plate 1 has a corresponding groove for mounting the support rod 5 (e.g., Figure 9 This improves stability.

[0042] Specifically, in order to achieve fixation after length adjustment, the panel also includes a positioning plate 8, which is provided with a fixing hole 801, a clamping piece 802 and a clamping block 803.

[0043] Multiple support rods 5 are provided, with at least one (e.g., ...). Figure 9 As shown, the outermost two support rods 5 have the following structure attached. The outer tube 501 of the support rod 5 is inserted into the fixing hole 801 at one end near the inner tube 502, and the clamping piece 802 is pressed by the clamping block 803 and makes contact with the inner tube 502.

[0044] like Figure 7 and 8 As shown, the positioning plate 8 has a fixed hole 801 integrally formed at its outer end, and the corresponding outer sleeve 501 is inserted into it. This insertion is an interference fit, meaning it has a large friction force and will not easily move or come apart. Then, a clip 802 is integrally formed on one side of the fixed hole 801. Figure 7 As shown, the clamping piece 802 has a notch. Made of plastic, this part has a certain degree of elastic deformation capability, and the inner tube 502 is located at this position. Furthermore, the clamping block 803 is rotatably connected to the positioning plate 8, and the shape of the clamping block 803 is as follows... Figure 8 As shown;

[0045] When the clamping block 803 is rotated, the clamping block 803 (using the eccentric large head) will squeeze the clamping piece 802, making it in close contact with the inner tube 502, increasing the friction. Since the clamping piece 802 is integrally formed with the fixing hole 801, and the fixing hole 801 is interference-fitted with the outer tube 501, the relative position of the outer tube 501 and the inner tube 502 is stable and will not move easily. Conversely, when adjustment is required, the clamping block 803 is rotated in the opposite direction to stop squeezing the clamping piece 802, and the pulling operation can be performed.

[0046] While increasing the number of plates and reducing the width of the carrier plate 1 can improve the matching accuracy, this approach is clearly detrimental to installation and stability. Therefore, the panel also includes a variable-sized adjustment plate 9, such as... Figure 9 As shown, the adjustment plate 9 is placed on one side (of course, there can be multiple plates), and a splitting crack 901 is pre-fabricated on it during production (as shown). Figure 12 The wall thickness here is relatively low, for example, less than 1mm. Depending on the actual situation, the excessively wide part can be torn off by hand to change the size of the adjustment plate 9 to meet the actual needs.

[0047] To allow for width adjustment (which, depending on the actual situation, could also be considered as adjusting the depth of the cabinet space), the horizontal frame 2 includes one horizontal bar I201 and two horizontal bars II202. The horizontal bars II202 are slidably inserted into the horizontal bar I201, and as shown... Figure 11 As shown, the inner end of the crossbar II202 is also provided with a wedge-shaped anti-detachment block to prevent the crossbar II202 from being easily pulled completely out of the crossbar I201.

[0048] Similarly, such as Figure 5 As shown, a single loading plate 1 is composed of two intersecting plates joined together (the joint has corresponding grooves and protrusions, and this joining method is already widely used, so it will not be elaborated further); similarly, to achieve adjustment in this direction, the adjustment plate 9 and positioning plate 8 also have a similar joining method, such as... Figure 9-13 It is clear that...

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
