Description

Technical Field

[0001] The utility model relates to the technical field of article storage, and particularly relates to a storage box. Background Art

[0002] In the catering industry, items such as packaged tissues are usually placed in a storage box. A taking opening is provided on the top surface of the storage box. Users take single sheets of tissue on the surface through the taking opening. The tissue on the surface drives adjacent layers of tissue to partially extend out of the taking opening, facilitating the next use by the user. As the tissue is used, the overall thickness of the tissue becomes thinner. Users need to insert their fingers through the taking opening into the interior of the storage box to take the tissue, which is very inconvenient to use.

[0003] In the existing storage box, two lifting ropes are arranged inside. The tissue is placed on the lifting ropes. By pulling the two lifting ropes respectively, the tissue is lifted, thereby reducing the distance between the tissue and the taking opening to facilitate the user to take the tissue. However, since the user needs to pull the two lifting ropes respectively and fix the two lifting ropes on the box body respectively, it is very inconvenient to use. Summary of the Utility Model

[0004] In view of this, the utility model provides a storage box to solve the problem that the existing storage box requires the user to pull the lifting ropes respectively to drive the items inside to rise to the required position and then fix the two lifting ropes respectively, which causes great inconvenience to the user.

[0005] The utility model provides a storage box, which comprises a box body, a lifter and at least two lifting members. The lifter is arranged on the first side wall of the box body. At least two of the lifting members are accommodated in the box body. The first ends of at least two of the lifting members are respectively positioned at a first position and a second position on the second side wall of the box body. The second ends of at least two of the lifting members are all connected to the lifter. Wherein, the first side wall is opposite to the second side wall, and the lifter is used to drive the second ends of at least two of the lifting members to move so that at least two of the lifting members move in the height direction of the box body.

[0006] Beneficial Effects: For the storage box of this application, the box body is used to place items to be used. As the items are used, their thickness gradually decreases.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0039] The following will be combined with Figures 1 to 5, describe the embodiments of the present utility model.

[0040] According to an embodiment of the present utility model, a storage box is provided, which includes a box body 1, a lifter 2, and at least two lifting members 3. Among them, the lifter 2 is arranged on the first side wall 11 of the box body 1, at least two lifting members 3 are accommodated in the box body 1, the first ends of at least two lifting members 3 are respectively positioned at the first position and the second position of the second side wall 12 of the box body 1, and the second ends of at least two lifting members 3 are all connected to the lifter 2. Among them, the first side wall 11 is opposite to the second side wall 12, and the lifter 2 is used to drive the second ends of at least two lifting members 3 to move so that at least two lifting members 3 move in the height direction of the box body 1.

[0041] For the storage box of the present application, the box body 1 is used to place the item 100 to be used. As the item 100 is used, its thickness gradually decreases. At this time, the lifter 2 and the lifting member 3 provided on the storage box drive the item 100 to rise along the height direction of the box body 1, which is convenient for the user to take the item 100 in the box body 1. Among them, the lifter 2 is set to drive the second ends of at least two lifting members 3 to move at the same time, and it is not necessary for the user to operate multiple lifting ropes respectively, which is more convenient to use and provides a better user experience.

[0042] In some embodiments, the box body 1 is provided with a top cover, and an opening 13 is provided on the top cover. The opening 13 is for the user to take the item 100 placed inside the box body 1. The item 100 is, for example, a tissue, or it can also be other items.

[0043] In some embodiments, the box body 1 is a square box body, and the first side wall 11 and the second side wall 12 oppositely arranged thereon are both rectangles. In other embodiments, the box body 1 can also be set to other geometric shapes, such as circular, oval, irregular polygon, etc. For example, when the box body 1 is set to circular or oval, there is no obvious boundary between the first side wall 11 and the second side wall 12 oppositely arranged thereon. When the box body 1 is set to an irregular polygon, there can be various combination ways for the side walls oppositely arranged thereon. Therefore, the first side wall 11 and the second side wall 12 being opposite is not limited to the positions shown in this embodiment. As long as the lifter 2 arranged on the first side wall 11 can drive the lifting member 3 whose first end is positioned on the second side wall 12 to move in the height direction of the box body 1 through the second end of the lifting member 3. For the convenience of description, the present application takes the storage box as a square box body as an example for description, but the present application is not limited thereto.

[0044] In some embodiments, the lifting member 3 is set as a rope. In other embodiments, the lifting member 3 is set as an elastic band. In still other embodiments, the lifting member 3 is set as a wire. Or, the lifting member 3 can also be set as other items that can achieve similar functions to the rope, which will not be elaborated here. For the convenience of description, the present application takes the lifting member 3 as a rope as an example for description, but the present application is not limited thereto.

[0045] In addition, at least two lifting members 3 are accommodated in the box body 1. In some embodiments, the number of the lifting members 3 is set to two so that the article 100 can be stably placed on the lifting members 3. In other embodiments, the number of the lifting members 3 is set to multiple to enhance the supporting effect on the article 100. In the case where multiple lifting members 3 are provided, the multiple lifting members 3 can be divided into two groups, and the two groups of lifting members 3 respectively correspond to the setting mode of the two lifting members 3. Alternatively, in the case where the lifting members 3 are multiple, positioning positions corresponding to the first ends of the multiple lifting members 3 are provided on the second side wall 12, and the second ends of the multiple lifting members 3 are all connected to the lifter 2. For the convenience of description, the present application takes the lifting members 3 being two as an example for description, but the present application is not limited thereto.

[0046] The first ends of the two lifting members 3 are respectively positioned at a first position and a second position on the second side wall 12 of the box body 1. In some embodiments, the first end of the lifting member 3 can be fixedly connected to the second side wall 12 of the box body 1. For example, the first end of the lifting member 3 is fixedly bonded to the second side wall 12 of the box body 1. In other embodiments, the first end of the lifting member 3 can be movably connected to the second side wall 12 of the box body 1. For example, holes are provided on the box body 1, and the first end of the lifting member 3 passes through the holes to be movably connected to the box body 1. In one example, through holes are provided at both the first position and the second position, and the first ends of the two lifting members 3 respectively pass through the corresponding through holes provided on the box body 1 and are independently connected to the box body 1. In another example, second through holes 121 are provided at both the first position and the second position, and the first ends of the two lifting members 3 respectively pass through the second through holes 121 and are connected to each other. Among them, in the case where the two lifting members 3 are connected to each other, the first ends of the two lifting members 3 can be connected by a connecting member or by tying a knot. Alternatively, the two lifting members 3 are formed by a single rope. Specifically, one end of a rope successively passes through the second through holes 121 provided at the first position and the second position and is connected to the lifter 2, and the other end of the rope is also connected to the lifter 2, thereby achieving the purpose of forming two lifting members 3 by a single rope to reduce the manufacturing cost.

[0047] In some embodiments, third through holes 112 corresponding to the second through holes 121 are provided on the first side wall 11, and the second ends of at least two lifting members 3 respectively pass out from the corresponding third through holes 112 and are connected to the lifter 2, so as to facilitate the installation connection between the lifting members 3 and the lifter 2.

[0048] In practical applications, in order to improve the stability of the article 100 during movement, in one embodiment, at least two lifting members 3 are cross - arranged in the box body 1.

[0049] By cross - arranging the lifting members 3, the lifting members 3 can cross on the bottom surface of the box body 1 to form a supporting surface, so as to stably support the article 100 thereon.

[0050] Further, the crossing positions of at least two lifting members 3 are fixedly connected to form a crossing point 31. In some embodiments, the crossing positions of the two lifting members 3 are fixed by bonding. In other embodiments, the crossing positions are fixed by fixing members. For example, a buckle is provided at the crossing position to snap the two lifting members 3 together.

[0051] Through the above settings, the crossing positions of the lifting members 3 can be fixed to form a stable crossing point 31, enhancing the stable support for the article 100 thereon.

[0052] In this embodiment, only one crossing point 31 is formed after the two lifting members 3 cross inside the box body 1. In other embodiments, multiple lifting members 3 can form multiple crossing points 31, which is not limited to this embodiment.

[0053] In practical applications, since the crossing point 31 will move towards the first side wall of the box body 1 as the lifting member 3 rises, in order to enable the article 100 to move fully inside the box body and avoid the situation where the crossing point contacts the side wall and affects the movement of the article, the initial position of the crossing point 31 is set such that when the lifting member 3 rises to the middle height of the box body 1, the crossing point 31 is located at the center position of the bottom surface of the box body 1.

[0054] Through the above settings, it can be ensured that the lifting member 3 can rise to the highest height of the box body 1, and thus the article 100 thereon can be conveyed to the highest position of the box body 1, and the crossing point 31 is always within the range of the bottom surface of the box body 1, avoiding the situation where the lifting member 3 cannot rise due to the crossing point 31 moving to the side wall of the box body 1.

[0055] In addition, the second ends of the lifting members 3 are all connected to the lifter 2, and the lifter 2 is used to drive the second ends of the lifting members 3 to move so that the lifting members 3 move in the height direction of the box body 1. In some embodiments, the lifter 2 is arranged to move relative to the first side wall 11, that is, by pulling / pushing the lifter 2 to drive at least two lifting members 3 to move in the height direction of the box body 1. In other embodiments, the lifter 2 is arranged to rotate relative to the first side wall 11 to drive at least two lifting members 3 to move in the height direction of the box body 1. In this application, the lifter 2 drives at least two lifting members 3 to move in the height direction of the box body 1 in a rotational manner, making the operation quick and saving operation space.

[0056] In some embodiments, when the lifter 2 rotates relative to the first side wall 11, the lifting member 3 is wound around the lifter 2 to drive the lifting member 3 to move in the height direction of the box body 1, so as to simultaneously store the lifting member 3 during the lifting process, saving operation space and making the storage box more concise.

[0057] For example, the lifter 2 includes a rotating shaft 22 and a winding portion 23 provided on the rotating shaft 22. Among them, the rotating shaft 22 is rotatably connected to the first side wall 11, and the winding portion 23 is sleeved on the outer periphery of the rotating shaft 22. When the rotating shaft 22 rotates relative to the first side wall 11, the lifting member 3 is driven to wind around the winding portion 23. For example, the winding portion 23 is arranged in a cylindrical shape and is fixedly sleeved on the outer wall of the rotating shaft 22 located on the first side wall 11 of the box body 1. In one example, the second ends of the two lifting members 3 are both connected to the winding portion 23. When the rotating shaft 22 is rotated to rotate relative to the first side wall 11, the rotating shaft 22 drives the lifting member 3 to wind around the winding portion 23, thereby realizing the winding and storage of the lifting member 3. In another example, two connection holes 231 for the lifting member 3 to pass through are provided on the side wall of the winding portion 23, and the second ends of the two lifting members 3 respectively pass through the two connection holes 231 and are connected to each other. Or in the case where a rope is used as the lifting member 3 as described above, as Figure 2 shown, the starting end of the rope can be placed at the intersection point 31, and the other end of the rope passes through the two second through holes 121 on the second side wall 12 from the inside of the box body 1 towards the second side wall 12 and then enters the storage box. After crossing the starting end of the rope in the box body 1, it passes through the third through hole 112 on the first side wall towards the first side wall 11, the two connection holes 231 on the winding portion 23, and another third through hole 112 on the first side wall 11, and finally converges with the starting end at the intersection point to form a lifting path (as Figure 2 shown by the arrow in).

[0058] In practical applications, in order to facilitate the operation of the lifter 2, in some embodiments, the first side wall 11 is provided with a first through hole 111, and the lifter 2 further includes a knob 21. The knob 21 is connected to the winding portion 23, and the rotating shaft 22 passes through the first through hole 111 to rotatably mount the lifter 2 on the first side wall 11.

[0059] The first through hole 111 facilitates the rotational connection of the rotating shaft 22 to the first side wall 11, thereby realizing the rotational mounting of the lifter 2 on the box body 1. The knob 21 facilitates the user to operate the lifter 2. The user drives the winding portion 23 and the rotating shaft 22 to rotate by rotating the knob 21, and then winds the lifting member 3 around the winding portion 23.

[0060] In some embodiments, the lifter 2 includes a shielding portion (not shown). The shielding portion is arranged on the box body 1 and is used to shield the lifting member 3 wound on the lifter 2 to improve the aesthetics of the entire storage box.

[0061] It can be understood that there is a winding space between the shielding portion and the winding portion 23, and the winding space is used to accommodate the lifting member 3 wound on the winding portion 23. For example, the shielding portion can be arranged in a cylindrical structure, and the winding portion 23 is arranged in the hollow of the cylindrical structure, so as to shield the winding portion 23 and the lifting member 3 wound thereon through the cylindrical structure.

[0062] In some embodiments, the shielding portion is provided with an avoidance hole through which the lifting member 3 passes. The second end of the lifting member 3 passes through the avoidance hole and is connected to the lifter 2. The provision of the avoidance hole facilitates the connection between the lifting member 3 and the lifter 2 and prevents the shielding portion from interfering with the connection between the lifting member 3 and the lifter 2.

[0063] Correspondingly, there are also two avoidance holes, and the two avoidance holes are arranged in one-to-one correspondence with the two connection holes 231 on the winding portion 23.

[0064] In practical applications, when the lifting member 3 is lifted to the required position, it needs to be held at that position. In some embodiments, the storage box further includes an anti-backward mechanism, which is used to position the lifter 2 after the force applied to the lifter 2 is removed, so that the lifting member 3 remains at the required position.

[0065] In some embodiments, the anti-backward mechanism includes a first concave-convex structure 232 provided on the lifter 2 and a second concave-convex structure 113 provided on the first side wall 11 and cooperating with the first concave-convex structure 232. After the force applied to the lifter 2 is removed, the first concave-convex structure 232 and the second concave-convex structure 113 are engaged with each other to prevent the lifting member 3 from moving backward and thus position the lifter 2.

[0066] During use, after the lifting member 3 is moved to the corresponding position by the lifter 2, the force applied to the lifter 2 is removed. The first concave-convex structure 232 and the second concave-convex structure 113 are engaged with each other to prevent the lifting member 3 from moving backward and thus position the lifter 2, ensuring the stability of the article 100 when used in the box body 1.

[0067] In some embodiments, the first concave-convex structure 232 and the second concave-convex structure 113 are provided in a serrated shape. The force applied to the lifter 2 drives the first concave-convex structure 232 to overcome the frictional force with the second concave-convex structure 113 so that the lifter 2 rotates relative to the first side wall 11. After the force applied to the lifter 2 is removed, the first concave-convex structure 232 and the second concave-convex structure 113 are engaged with each other to prevent the lifter 2 from rotating back and thus position the lifter 2.

[0068] In this application, the first concave-convex structure 232 and the second concave-convex structure 113 are set to be serrated. By the force applied to the lifter 2, the first concave-convex structure 232 is driven to rotate relative to the second concave-convex structure 113 while overcoming the frictional force between them, thereby realizing the damped rotation of the lifter 2 relative to the first side wall 11, so as to drive the lifting member 3 to move in the height direction of the box body 1. After the force applied to the lifter 2 is removed, the frictional force between the first concave-convex structure 232 and the second concave-convex structure 113 causes the first concave-convex structure 232 and the second concave-convex structure 113 to engage with each other to prevent the lifter 2 from rotating back, thereby positioning the lifter 2.

[0069] When the lifter 2 includes a winding portion 23 as described above, the first concave-convex structure 232 is provided on the end face of the winding portion 23 facing the first side wall 11, and the second concave-convex structure 113 is provided on the end face of the first side wall 11 facing the winding portion 23. Rotating the knob 21 drives the winding portion 23 to rotate, and then drives the first concave-convex structure 232 on the winding portion 23 to rotate relative to the second concave-convex structure 113 on the first side wall 11, so as to realize the rotational movement of the lifter 2.

[0070] When the lifter 2 includes a shielding portion as described above, the shielding portion is provided on the first side wall of the box body 1, the winding portion 23 is arranged inside the shielding portion, the first concave-convex structure 232 is provided on the end face of the knob 21 facing the shielding portion, and the second concave-convex structure 113 is provided on the end face of the shielding portion facing the knob 21. When the knob 21 is rotated to rotate relative to the shielding portion, the knob 21 drives the first concave-convex structure 232 thereon to rotate relative to the second concave-convex structure 113 on the shielding portion, so as to realize the rotational movement of the lifter 2.

[0071] It should be noted that the first concave-convex structure 232 and the second concave-convex structure 113 can be set to be integrally matched or partially matched. That is, the first concave-convex structure 232 is arranged in an annular serrated structure on the end face, and the second concave-convex structure 113 is also arranged in an annular serrated structure, so that the two are integrally matched to increase the frictional force. Or, one of the first concave-convex structure 232 and the second concave-convex structure 113 is arranged in an annular serrated structure, and the other is arranged in a partial serrated structure, so that the first concave-convex structure 232 and the second concave-convex structure 113 are partially matched to reduce the manufacturing cost.

[0072] In some embodiments, the anti-back-off mechanism further includes an elastic member 25. A limiting portion 24 is provided at one end of the rotating shaft 22 away from the knob 21, and the elastic member 25 is disposed between the limiting portion 24 and the first side wall 11. The limiting portion 24 is used to limit the position between the rotating shaft 22 and the first side wall 11. The elastic member 25 is placed between the limiting portion 24 and the first side wall 11. Through the elastic deformation force of the elastic member 25, the cooperation between the knob 21 and the first side wall 11 of the box body 1 is made closer, and the engagement between the first concave-convex structure 232 and the second concave-convex structure 113 is also tighter, thereby enhancing the positioning effect on the lifter 2. In one example, the elastic member 25 is provided as an elastic gasket. In another example, the elastic member 25 is provided as a spring. For example, the spring is sleeved on the outer periphery of the rotating shaft 22, one end of the spring abuts against the limiting portion 24, and the other end abuts against the first side wall 11.

[0073] In addition, during use, when the lifter 2 needs to be rotated, the knob 21 can be pulled out in a direction away from the box body 1. At this time, the elastic member 25 is compressed and deformed, and at the same time, the first concave-convex structure 232 on the knob 21 disengages from the second concave-convex structure 113, and the two are separated. In the case of their separation, the knob 21 is rotated to drive the lifting member 3 to be wound around the winding portion 23, making the lifting process more labor-saving.

[0074] When rotated to the specified position, the force applied to the knob 21 is removed, and the deformation force of the elastic member 25 drives the knob 21 to fit against the first side wall 11 of the box body 1, so that the first concave-convex structure 232 is tightly engaged with the second concave-convex structure 113, and the two are clamped and fixed to achieve the positioning of the lifter 2.

[0075] In some embodiments, the limiting portion 24 is provided as an end cap. The end cap is connected to the other end of the rotating shaft 22 away from the knob 21 to clamp the lifter 2 on the first side wall 11, ensuring the structural reliability of the connection between the lifter 2 and the box body 1.

[0076] Specifically, the end cap is circular, and its diameter is larger than the aperture of the first through hole 111, so that the end cap cannot pass through the first through hole 111 and thus the rotating shaft 22 is limited in the first through hole 111.

[0077] To facilitate understanding of the storage box of this embodiment, the following describes its usage process in combination with the attached Figure 1 to the attached Figure 5 , as follows:

[0078] When it is necessary to adjust the height of the article 100, pull out the knob 21 outward, so that the elastic member 25 is compressed and deformed. At the same time, the first concave-convex structure 232 is driven to disengage from the second concave-convex structure 113, and the two are separated. Then rotate the knob 21 to drive the rotating shaft 22 and the winding portion 23 to rotate together, so that the lifting member 3 rises along the height direction of the box body 1. At the same time, the intersection point 31 of the lifting member 3 moves toward the side of the lifter 2 and the lifting member 3 is wound around the winding portion 23, realizing the rise of the article 100 in the box body 1;

[0079] When the article 100 reaches the specified height, remove the force applied to the knob 21. The deformation force of the elastic member 25 drives the knob 21 to fit against the first side wall 11 of the box body 1, so that the first concave-convex structure 232 is tightly engaged with the second concave-convex structure 113, and the two are clamped and fixed, preventing the lifting member 3 from retracting, realizing the positioning of the lifter 2, and ensuring the use stability of the article 100.

[0080] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
