Description

Technical Field

[0001] This application relates to the field of storage device technology, and in particular to a storage box. Background Technology

[0002] In daily life, we frequently use various types of pens, such as pencils, ballpoint pens, felt-tip pens, and markers. In addition, we use various office supplies, such as paper clips and erasers. Users typically use storage boxes to organize these items.

[0003] In existing technologies, storage boxes generally lack handles. Users need to lift the bottom when moving the storage box, which is not only inconvenient but also easily causes items inside to scatter. Therefore, a small number of storage boxes are equipped with handles, which are usually directly fixed to the main frame of the storage box with adhesive. However, ordinary adhesives are prone to aging under long-term stress or changes in temperature and humidity, leading to a decrease in bonding strength. This causes the connection between the handle and the frame to gradually loosen, posing a risk of the handle falling off. Utility Model Content

[0004] This utility model provides a storage box to solve the technical problem that the handles of storage boxes in the prior art are easy to fall off.

[0005] To achieve the above objectives, the storage box proposed in this application includes a frame and a handle. The frame includes an outer frame, an inner frame, and a base plate. The outer frame and the inner frame are both arranged in a ring and coaxially mounted on the base plate. The inner frame has a first slot, and the inner wall of the outer frame has a plurality of first mortises, with at least two of the first mortises arranged opposite each other. The bottom of the handle plate has a second slot, and both sides of the handle plate have tenons. The first slot and the second slot are interlocked to install the handle plate onto the inner frame. The two tenons are respectively installed in the two opposite first mortises to fix the handle plate onto the outer frame.

[0006] Optionally, in one embodiment, the frame further includes multiple partitions, and the inner frame has multiple second mortises on its side facing the outer frame. The second mortises are corresponding to the first mortises. One end of the partition is installed in the first mortis, and the other end of the partition is installed in the corresponding second mortis.

The base has a bracket groove on the side facing the bottom plate. The bracket is disposed in the bracket groove, and the height of the side wall of the bracket groove is less than the diameter of the balls, so that the balls extend out of the bracket groove and abut against the bottom plate.

[0015] The storage box provided in this application achieves dual fixation of the handle plate and the frame through the interlocking of the first slot and the second slot, and the tight fitting of the tenon and the first mortise.

[0030] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] This application provides a storage box to solve the technical problem that the handle of a storage box in the prior art is prone to detachment. The following description is in conjunction with the accompanying drawings.

[0033] In the embodiments of this application, such as Figures 1-4 As shown, the storage box includes a frame 10 and a handle 20. The frame 10 includes an outer frame 11, an inner frame 12, and a base plate 13. The outer frame 11 and the inner frame 12 are both arranged in a ring and coaxially mounted on the base plate 13. The inner frame 12 is provided with a first slot 121, and the inner wall of the outer frame 11 is provided with a plurality of first mortises 111, at least two of which are arranged opposite to each other. The bottom of the handle 20 is provided with a second slot 21, and both sides of the handle 20 are provided with tenons 22. The first slot 121 and the second slot 21 are interlocked to install the handle 20 on the inner frame 12. The two tenons 22 are respectively installed in the two opposite first mortises 111 to fix the handle 20 on the outer frame 11.

[0034] It should be noted that most storage boxes in the current technology lack handles. Users need to lift the bottom when moving the storage box, which is not only inconvenient but also easily causes items inside the storage rack to scatter. While some storage boxes do have handles, the handle panels are mostly fixed directly to the main frame of the storage box with adhesive. Ordinary adhesives are prone to aging under long-term stress or changes in temperature and humidity, resulting in a decrease in bonding strength. The connection between the handle and the frame will gradually loosen, and the handle may fall off.

[0035] To this end, the storage box provided in this application achieves dual fixation between the handle plate 20 and the frame 10 through the interlocking of the first slot 121 and the second slot 21, and the tight fitting of the tenon 22 and the first mortise 111. This ensures that the handle plate 20 bears the load evenly on both sides when under stress, and the load is transferred to the entire frame 10 through the mortise and tenon structure. This avoids the risk of breakage or detachment caused by local stress concentration and improves the stability of the overall structure. Compared with the traditional adhesive fixing method, the storage box provided in this application can avoid the problem of loose connection caused by adhesive aging, and significantly improves the service life and load-bearing capacity of the handle plate 20.

[0036] For details, please refer to Figures 1-4Both the first slot 121 and the second slot 21 can be U-shaped grooves. The first slot 121 is located at the top of the inner frame 12, and its width is adapted to the thickness of the handle plate 20. The width of the second slot 21 is adapted to the wall thickness of the inner frame 12. During assembly, the handle plate 20 is initially fixed to the inner frame 12 by interlocking the second slot 21 of the handle plate 20 with the first slot 121 of the inner frame 12. For example, the width of the first slot 121, the thickness of the handle plate 20, the width of the second slot 21, and the wall thickness of the inner frame 12 are all 6mm. The 6mm groove width design provides sufficient contact area and avoids cracking due to local stress concentration caused by excessively small groove width.

[0037] like Figure 3 As shown, the handle plate 20 is flat, and two tenons 22 are symmetrically arranged on both sides of the handle plate 20. The tenons 22 can be cuboid in shape. In this embodiment, the tenons 22 and the handle plate 20 are an integral structure. The integral structure not only eliminates the steps of separately processing and assembling the tenons 22, but also avoids the risk of breakage due to stress concentration. Figure 4 and Figure 6 As shown, a vertical first mortise 111 is provided on the inner side of the outer frame 11. In the height direction of the storage box, the first mortise 111 extends to the bottom of the outer frame 11 but does not extend to the top of the outer frame 11. The width of the first mortise 111 is adapted to the thickness of the tenon 22. After the handle plate 20 is initially fixed to the inner frame 12, the outer frame 11 is assembled with the handle plate 20 along the height direction of the storage box, so that the two tenons 22 can be embedded into the corresponding first mortise 111. In this embodiment, the first slot 121 and the second slot 21 cooperate to realize the lateral limitation of the handle plate 20, and then the tenon 22 cooperates with the first mortise 111 to realize the longitudinal limitation of the handle plate 20. When the storage box is lifted, since the handle plate 20 is evenly stressed on both sides of the outer frame 11, the overall structure of the storage box is stable and the handle plate 20 is not easy to fall off.

[0038] In some embodiments, the mortise and tenon joint surfaces of the handle plate 20 and the outer frame 11 are coated with adhesive. The handle plate 20 is double-fixed by the mortise and tenon structure and the adhesive connection, which can effectively resist the impact force of the handle plate 20 when it is lifted or dropped, and further improve the stability of the overall structure of the storage box. In addition, even if the adhesive ages due to temperature and humidity changes, the mortise and tenon structure can still maintain a stable connection between the handle plate 20 and the frame 10.

[0039] Optionally, in one embodiment, please refer to Figures 4-6The frame 10 also includes multiple partitions 14. Multiple second mortises 122 are provided on the side of the inner frame 12 facing the outer frame 11. The second mortises 122 are corresponding to the first mortises 111. One end of the partition 14 is installed in the first mortises 111, and the other end of the partition 14 is installed in the corresponding second mortises 122.

[0040] Specifically, in the height direction of the storage box, the second tenon 122 extends to the bottom of the inner frame 12 but not to the top of the outer frame 11. The partition 14 is a rectangular plate structure. After inserting both ends of the partition 14 into the first tenon 111 and the second tenon 122 respectively, the inner frame 12 and the outer frame 11 are supported as a whole by the partition 14, enhancing the stability of the structure. In addition, the number of partitions 14 can be increased or decreased according to the user's needs to achieve customized division of storage space and improve the flexibility of space layout.

[0041] Optionally, in one embodiment, please refer to Figures 4-6 The cross-sections of the outer frame 11 and the inner frame 12 are both regular octagons. Each side of the outer frame 11 is provided with a first tenon 111. The handle plate 20 is connected to two opposite first tenons 111. Three partitions 14 are distributed on each side of the handle plate 20.

[0042] In this embodiment, the storage box has an octagonal prism structure, which not only provides structural stability but also enhances the overall aesthetics. Each inner sidewall of the outer frame 11 is provided with a vertical first tenon 111, and the eight first tenons 111 are evenly distributed in an array. The inner frame 12 is provided with two first slots 121 and six second tenons 122. The two first slots 121 are respectively provided on two opposite side plates of the inner frame 12, and each of the other sides of the inner frame 12 is provided with a second tenon 122, and the second tenons 122 are aligned with the corresponding first tenons 111. The handle plate 20 is provided with two second slots 21, which are inserted into the two first slots 121 one by one. The tenons 22 at both ends of the handle plate 20 are inserted into the two first mortises 111 on the outer frame 11. The six partitions 14 are respectively inserted into the remaining six first mortises 111 and the corresponding six second mortises 122. Through the arrangement of the handle plate 20 and the six partitions 14, eight independent partitions are formed between the inner frame 12 and the outer frame 11. The interior of the inner frame 12 is divided into two independent partitions by the handle plate 20. In this embodiment, the frame 10 is provided with ten independent partitions, which optimizes the classification and storage capacity of the storage box and makes it more convenient to take out and put in.

[0043] Optionally, in one embodiment, please refer to Figure 1 , Figure 3 and Figure 6The handle plate 20 has a handle hole 23, and baffles 15 are fixedly connected to both sides of the handle plate 20. Both baffles 15 are located inside the inner frame 12, and the handle hole 23 is located above the two baffles 15. The handle hole 23 is located in the middle of the top of the handle plate 20 for easy gripping. The two baffles 15 can be fixedly connected to the handle plate 20 by means of adhesive or screws. When the storage box contains a lot of items, since the handle hole 23 is located above the two baffles 15, the two baffles 15 can prevent items from getting close to the handle hole 23, ensuring that fingers will not be obstructed when inserting them into the handle hole 23, thus improving the practicality of the storage box.

[0044] In some embodiments, the shape of the handle hole 23 can also be set to be wavy or elliptical to fit the user's hand shape.

[0045] Optionally, in one embodiment, please refer to Figure 6 and Figure 8 The base plate 13 is provided with a limiting groove 131, and one end of the inner frame 12 is installed in the limiting groove 131; and / or, the outer edge of the base plate 13 is provided with a limiting step 132, and the outer frame 11 is installed on the limiting step 132.

[0046] Specifically, in this embodiment, both the inner frame 12 and the outer frame 11 are annular structures, such as circular, elliptical, or polygonal, and are fixedly installed on the base plate 13 by coaxial nesting to form a stable double-layer storage structure. The shape of the limiting groove 131 is adapted to the inner frame 12, and the limiting groove 131 can limit the inner frame 12 to prevent it from shifting or tilting; at the same time, the bottom of the outer frame 11 is fitted onto the limiting step 132 to ensure the alignment and fixation of the outer frame 11 with the base plate 13. In this embodiment, the setting of the limiting groove 131 and the limiting step 132 simplifies the installation of the storage box and improves the assembly efficiency of the storage box.

[0047] Optionally, in one embodiment, please refer to Figure 10 and Figure 11 The outer frame 11 has a circular or regular hexagonal cross-section; and / or, the inner frame 12 has a circular or regular hexagonal cross-section. By setting combinations of inner frame 12 and outer frame 11 with different shapes, the appearance of the product can be more diversified and it can be applied to different usage scenarios.

[0048] Optionally, in one embodiment, please refer to Figure 6The storage box also includes a base 30 and a rotating mechanism 40. One end of the rotating mechanism 40 is connected to the base 30, and the other end is connected to the frame 10, so that the base 30 and the frame 10 are rotatably connected. Since the frame 10 can rotate on the base 30, when it is necessary to store or retrieve items, the user can rotate the frame 10 to bring different positions in the storage compartment closer to the user. The user can quickly find the required position in the storage compartment, realizing efficient searching, retrieval, and placement of items.

[0049] Further, please refer to Figure 7 The rotating mechanism 40 includes a rotating shaft 41, one end of which is fixedly connected to the base plate 13, and the other end of which is rotatably connected to the base 30. In this embodiment, the rotating shaft 41 is fixed to the base plate 13 and can rotate relative to the base 30. When the frame 10 rotates, the frame 10 and the rotating shaft 41 rotate synchronously.

[0050] Furthermore, such as Figure 7 As shown, the rotating shaft 41 is a screw, the base 30 is provided with a first mounting hole 31, the base plate 13 is provided with a second mounting hole 133, a nut 134 is fixedly connected in the second mounting hole 133, and one end of the screw passes through the first mounting hole 31 and is threadedly connected to the nut 134.

[0051] The first mounting hole 31 is the center hole of the base 30, and the second mounting hole 133 is the center hole of the base plate 13. The frame 10 and the base 30 can be rotatably connected by the cooperation of screws and nuts 134, and the head of the screw can limit the base 30 to prevent the base 30 from falling off.

[0052] Optionally, in one embodiment, please refer to Figure 2 , Figure 6 and Figure 8 The rotating mechanism 40 also includes a bracket 42 and a plurality of balls 43 disposed on the bracket 42. The base 30 has a bracket groove 32 on the side facing the base plate 13. The bracket 42 is disposed in the bracket groove 32, and the height of the side wall of the bracket groove 32 is less than the diameter of the balls 43, so that the balls 43 extend out of the bracket groove 32 and abut against the base plate 13.

[0053] Specifically, the bracket 42 is arranged in a circular shape, and correspondingly, the bracket groove 32 is also arranged in a circular shape. Since the bracket 42 is set in the bracket groove 32, the bracket groove 32 can be formed as a guide rail for limiting the movement trajectory of the bracket 42. The two sides of the ball bearing 43 protrude from the bracket 42, so that one side of the ball bearing 43 abuts against the base plate 13, forming a support point at the bottom of the frame 10, and the other side of the ball bearing 43 abuts against the bottom of the bracket groove 32. When the frame 10 is rotated, the frame 10 can drive the ball bearing 43 to roll, effectively reducing the friction when the frame 10 rotates, making the frame 10 rotate more smoothly on the base 30.
