Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, specifically a rotatable and height-adjustable tissue box. Background Technology

[0002] Tissue boxes are common household items used to store tissues for easy access. Currently, most tissue boxes on the market have a fixed structure with a fixed internal height. As the tissues in the box gradually decrease, some settle at the bottom, making them inconvenient to retrieve. Users often have to reach deep into the box to get them, especially with deeper tissue boxes, resulting in a poor user experience.

[0003] To address the aforementioned issues, some tissue boxes with lifting functions have appeared on the market. However, the lifting structures of these tissue boxes are mostly complex, inconvenient to operate, and their stability and durability need improvement, making it difficult to meet users' actual needs. Therefore, there is a need for a tissue box with a simple structure, easy operation, and stable lifting function to overcome the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this utility model is to provide a rotatable and liftable tissue box to solve the problems mentioned in the background art, such as the inconvenience of using existing tissue boxes when the remaining amount of tissue is small, and the complex structure, inconvenient operation, poor stability and durability of some tissue boxes with lifting function.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rotatable and liftable tissue box, comprising a tissue box and a lid, wherein a rotatable and liftable mechanism is provided at the bottom of the tissue box, and a movable partition is provided at the top of the rotatable and liftable mechanism, the movable partition being slidably connected to the inside of the tissue box.

[0006] Furthermore, the rotating lifting mechanism includes a lower support plate fixed to the bottom of the tissue box. A pair of left support rods are movably disposed on the left end of the lower support plate. A pair of lower guide rods are disposed on the lower support plate. A lower sliding block is slidably connected to the lower guide rod. A pair of right support rods are movably disposed on the lower sliding block. An upper top plate is movably disposed at the other end of the right support rod. A pair of upper guide rods are disposed on the upper top plate. An upper sliding block is slidably connected to the upper guide rod. The top end of the left support rod is movably connected to the upper sliding block. A lead screw is disposed on the lower support plate. The lead screw is threadedly connected to the lower sliding block. One end of the lead screw passes through the tissue box and is fixedly disposed with a knob. The left and right support rods are movably connected.

[0007] Furthermore, the outer surface of the knob is provided with anti-slip texture, which is a strip-shaped raised ridge evenly distributed along the circumference of the knob.

[0008] Furthermore, the inner wall of the tissue box is symmetrically provided with vertical grooves, and the two sides of the movable partition are provided with sliding protrusions that are adapted to the vertical grooves. The sliding protrusions are embedded in the vertical grooves and slide along them.

[0009] Furthermore, the left support rod and the right support rod are movably connected by a connecting pin, and both ends of the connecting pin are fitted with wear-resistant rubber sleeves.

[0010] Furthermore, a sealing ring is provided at the penetration point between the lead screw and the tissue box. The sealing ring is made of rubber and fits tightly against the outer wall of the lead screw.

[0011] Furthermore, both the lower support plate and the upper top plate are made of stainless steel, and the edges of both are rounded.

[0012] Furthermore, the top of the box cover is provided with a paper outlet, and the edge of the paper outlet is provided with an arc-shaped transition portion.

[0013] The core working principle of this rotatable and height-adjustable tissue box is based on the linkage of a rotary lifting mechanism. When the user rotates the knob, the lead screw fixedly connected to the knob rotates accordingly. Since the lead screw is threadedly connected to the lower sliding block, and the lower sliding block is slidably connected to the lower guide rod, the rotation of the lead screw is converted into the horizontal sliding of the lower sliding block along the lower guide rod.

[0014] When the lower sliding block moves to the left, it causes the lower end of the right support rod, which is movably connected to it, to move to the left, gradually reducing the angle between the right support rod and the lower support plate. Simultaneously, because the left and right support rods are movably connected by a connecting pin, the movement of the right support rod also causes the left support rod to rotate. The top of the left support rod pushes the upper sliding block to slide to the right along the upper guide rod, causing the angle between the left and right support rods to gradually decrease. This raises the height of the entire rotating lifting mechanism, causing the upper top plate to move upwards, which in turn pushes the movable partition along the vertical groove on the inner wall of the tissue box, pushing the tissues upwards.

[0015] Conversely, when the sliding block moves to the right, the lower end of the right support rod moves to the right, the angle between the left and right support rods gradually increases, the height of the rotating lifting mechanism decreases, and the movable partition slides downward under its own weight and the pressure of the tissue paper. In this way, the height of the movable partition can be adjusted, making it convenient for users to take different amounts of tissue paper.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention, by setting up a rotating lifting mechanism, allows for convenient adjustment of the height of the movable partition. When there is a small amount of tissue paper remaining, the movable partition can be raised by rotating the knob, pushing the tissue paper to an easily accessible position, thus solving the problem of inconvenience in taking out the remaining tissue paper from traditional tissue boxes.

[0018] The anti-slip texture on the outer surface of the knob consists of evenly distributed circumferential ridges, which increases the friction between the hand and the knob, making rotation easier and more convenient, and preventing slippage.

[0019] The movable partition is slidably connected to the vertical groove on the inner wall of the tissue box via a sliding protrusion. This structure ensures the stability of the movable partition during the lifting and lowering process and prevents it from shifting or shaking. Attached Figure Description

[0028] 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.

[0029] Example 1

[0030] like Figure 1-4 As shown;

[0031] A rotatable and height-adjustable tissue box.

[0032] This implementation plan addresses the technical problems existing in the prior art, as disclosed in the background section above: "Tissue boxes are common household items used to store tissues for easy access. Currently, most tissue boxes on the market have a fixed structure with a fixed internal height. As the amount of tissues in the box gradually decreases, when only a small amount remains, the tissues sink to the bottom, making it very inconvenient for users to retrieve them. Often, users need to reach deep into the box to retrieve them, especially with deeper tissue boxes, where this inconvenience is more pronounced, resulting in a poor user experience."

[0033] To address the aforementioned issues, some tissue boxes with lifting functions have appeared on the market. However, the lifting structures of these tissue boxes are mostly quite complex, not convenient to operate, and their stability and durability need improvement, making it difficult to meet the actual needs of users. In practical terms, this problem is clearly a real and difficult-to-solve issue. Therefore, to solve this technical problem, a rotatable and lifting tissue box is provided.

[0034] like Figure 1-4 As shown in the figure;

[0035] This utility model provides a technical solution: a rotatable and liftable tissue box, including a tissue box 1 and a lid 2. A rotatable and liftable mechanism 3 is fixedly installed at the bottom of the tissue box 1. A movable partition 4 is provided at the top of the rotatable and liftable mechanism 3. The movable partition 4 is slidably connected to the inside of the tissue box 1.

[0036] The rotating lifting mechanism 3 includes a lower support plate 31 fixed to the bottom of the tissue box 1. A pair of left support rods 32 are movably mounted on the left end of the lower support plate 31 via a pin. A pair of lower guide rods 33 are welded to the lower support plate 31. A lower sliding block 34 is slidably connected to the lower guide rods 33. A pair of right support rods 35 are movably mounted on the lower sliding block 34 via a pin. An upper top plate 36 is movably mounted on the other end of the right support rods 35 via a pin. A pair of upper guide rods 361 are welded to the upper top plate 36. An upper sliding block 362 is slidably connected to the upper guide rods 361. The top end of the left support rod 32 is movably connected to the upper sliding block 362 via a pin. A lead screw 37 is mounted on the lower support plate 31 via a bearing seat. The lead screw 37 is threadedly connected to the lower sliding block 34. One end of the lead screw 37 passes through the tissue box 1 and is welded with a knob 38. The left support rods 32 and the right support rods 35 are movably connected by a connecting pin.

[0037] The outer surface of the knob 38 is integrally molded with anti-slip texture, which consists of strip-shaped raised ridges evenly distributed around the circumference of the knob 38.

[0038] The inner wall of the tissue box 1 is symmetrically provided with vertical grooves. The two sides of the movable partition 4 are integrally formed with sliding protrusions that are adapted to the vertical grooves. The sliding protrusions are embedded in the vertical grooves and slide along them.

[0039] Both ends of the connecting pin between the left support rod 32 and the right support rod 35 are fitted with wear-resistant rubber sleeves. The wear-resistant rubber sleeves are made of nitrile rubber and have good wear resistance and elasticity.

[0040] A sealing ring is installed at the point where the lead screw 37 passes through the tissue box 1. The sealing ring is made of rubber and fits tightly against the outer wall of the lead screw 37. The sealing ring is made of food-grade silicone to ensure safety during use.

[0041] Both the lower support plate 31 and the upper top plate 36 are made of 304 stainless steel, and the edges of both are rounded with a radius of 2mm.

[0042] The top of the cover 2 has a paper outlet, and the edge of the paper outlet has an arc-shaped transition section with a radius of curvature of 5mm.

[0043] The working process of this embodiment is as follows: When tissues need to be placed, open the lid 2, neatly stack the tissues on the movable partition 4, and then close the lid 2. When the tissues gradually decrease and become inconvenient to take, the user holds the knob 38 and rotates the knob 38 clockwise. The knob 38 drives the lead screw 37 to rotate. Since the lead screw 37 is threadedly connected to the lower sliding block 34, the lower sliding block 34 will slide to the left along the lower guide rod 33. The sliding of the lower sliding block 34 causes the lower end of the right support rod 35 to move to the left, reducing the angle between the right support rod 35 and the lower support plate 31. Simultaneously, the right support rod 35, through the connecting pin, drives the left support rod 32 to rotate. The top of the left support rod 32 pushes the upper sliding block 362 to slide to the right along the upper guide rod 361, further reducing the angle between the left support rod 32 and the right support rod 35. This raises the overall height of the rotating lifting mechanism 3, causing the upper top plate 36 to push the movable partition 4 upwards along the vertical groove, pushing the tissue upwards until it is in a convenient position. When it is necessary to lower the movable partition 4, rotating the knob 38 counterclockwise causes the lower sliding block 34 to slide to the right along the lower guide rod 33, lowering the height of the rotating lifting mechanism 3 and causing the movable partition 4 to descend accordingly.

[0044] Throughout the entire process, the wear-resistant rubber sleeves at both ends of the connecting pin reduce friction and wear between the left support rod 32 and the right support rod 35; the sealing ring effectively prevents external dust and moisture from entering the tissue box 1; the stainless steel lower support plate 31 and upper top plate 36 ensure the stability and durability of the structure; and the sliding connection structure of the movable partition 4 ensures the smoothness of the lifting process.

[0045] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
