Description

Technical Field

[0001] This utility model relates to a tissue box, specifically a tissue box with a central structure, and belongs to the field of tissue box technology. Background Technology

[0002] In places like restrooms, tissue boxes for toilet paper are often installed. To use it, open the lid, place the toilet paper roll inside, pull the end of the roll out of the box, and then close the lid. At this point, the user can simply pull the end of the roll out to continuously dispense toilet paper.

[0003] However, due to its cylindrical structure, toilet paper rolls are prone to rolling and shifting within an unrestrained box. When pulling out the roll, the tension generated by the paper being pulled will cause the roll to tilt to one side. Furthermore, since there are no guides or limits inside the box, the edge of the roll is prone to rubbing against the side wall of the box or even getting stuck in the gap, resulting in a sudden increase in extraction resistance. This can not only cause the paper to tear or break, but may also deform the roll core due to excessive pulling, making it difficult to continue pulling out the remaining paper. Utility Model Content

[0004] The purpose of this utility model is to provide a tissue box with a centering structure to solve the above problems. The rotating rod and the sliding rod are connected by threads. Rotating the rotating rod can drive the sliding rod to slide along the fixed rod, which will drive the baffle to move laterally. The baffles on both sides adjust the position of the insertion rod simultaneously, and symmetrical force can be applied from both ends of the tissue to ensure that the tissue is always centered and aligned with the tissue tray, avoiding problems such as sticking and tissue breakage caused by misalignment.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a tissue box with a centering structure, comprising a box body, a tissue slot at the bottom of the box body, a guide mechanism slidably installed inside the box body, the guide mechanism comprising a rotating rod and a fixed rod, fixed rods installed on both sides of the box body, a rotating rod rotatably connected to the fixed rod, a sliding rod threadedly connected to the rotating rod, the sliding rod and the fixed rod being slidably connected, a baffle fixedly connected to the sliding rod, a locking rod and an insert rod respectively fixed on both sides of the baffle, and a plurality of sets of ball bearings rotatably mounted in a ring at equal intervals on the insert rod.

[0006] Preferably, both the locking rod and the sliding rod are slidably connected to the box body, the end of the locking rod near the baffle is configured in a cross shape, and the end of the locking rod away from the baffle is configured in a circular shape.

[0007] Preferably, both the locking rod and the sliding rod are located on the side of the baffle away from the insertion rod, and the diameter of the baffle is larger than the diameter of the insertion rod.

[0008] Preferably, a sealing mechanism is installed on the top of the box body. The sealing mechanism includes a support plate and a placement groove. The support plate is installed on the top of the box body, and the top of the support plate is provided with a placement groove. The support plate is arranged in an L-shape.

[0009] Preferably, the sealing mechanism further includes locking blocks, and two locking blocks are symmetrically fixedly connected to the side wall of the support plate, with traceless adhesive clips engaged on the locking blocks.

[0010] Preferably, a limiting mechanism is fixed on the support plate. The limiting mechanism includes a limiting frame and a stop block. Two limiting frames are symmetrically fixedly connected to the bottom end of the support plate. A connecting shaft is fixedly installed on the limiting frame, and a stop block is rotatably connected to the connecting shaft.

[0011] Preferably, the limiting mechanism further includes a slot, and slots are provided on both sides of the box body. The box body and the limiting frame are engaged and connected, and the limiting frame is located in the slot.

[0012] Preferably, the limiting mechanism further includes a card plate, which is fixedly installed on the part of the box body near the card slot, and the card plate is engaged with the limiting frame.

[0013] Preferably, the abutment block and the clamping plate are rotatably connected, and the clamping plate is arranged in an L-shape.

[0014] The beneficial effects of this utility model are as follows: the rotating rod and the sliding rod are threaded together. When the rotating rod is rotated, the sliding rod slides along the fixed rod, which can drive the baffle to move laterally, so as to achieve centering alignment of tissues of different sizes. By adjusting the distance between the two baffles, it is ensured that the tissues are always in the center of the box and avoids offset. The baffle contacts the tissues through the insert rod. The ball bearing on the insert rod can roll with the tissues as they rotate, turning sliding friction into rolling friction, reducing wear on the surface of the tissues and preventing the edges of the tissues from getting fuzzy or damaged. The width of the baffle is adapted to the inside of the box. When the two sides are adjusted simultaneously, symmetrical forces can be applied from both ends of the tissues to ensure that the axis of the tissues is aligned with the tissue tray, solving the problems of tissue offset in the tissue box, such as sticking and unsmooth tissue pulling. The locking rod and the sliding rod extend from both sides of the baffle and slide to the box, forming a double guide structure, which prevents the baffle from tilting during adjustment or use and further ensures the centering accuracy.

[0021] 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.

[0022] Please see Figures 1-5As shown, a tissue box with a centering structure includes a box body 3. The bottom of the box body 3 has a tissue dispenser 4. A guide mechanism 5 is slidably installed inside the box body 3. The guide mechanism 5 includes a rotating rod 501 and a fixed rod 502. Fixed rods 502 are installed on both sides of the box body 3. A rotating rod 501 is rotatably connected to the fixed rod 502. A sliding rod 505 is threadedly connected to the rotating rod 501. The sliding rod 505 is slidably connected to the fixed rod 502. A baffle 504 is fixedly connected to the sliding rod 505. The rotation of the rotating rod 501 causes the sliding rod 505 to slide linearly along the fixed rod 502. During the movement of the sliding rod 505, the baffle 504 connected to it also moves synchronously. The rotating rods 501 on both sides need to rotate synchronously to ensure symmetrical adjustment of the baffles 504 on both sides. A locking rod 503 and an insert rod 506 are fixed to both sides of the baffle 504 respectively. Both the locking rod 503 and the sliding rod 505 slide against the box body 3. The movable connection features a ring-shaped, equidistantly rotating ball bearing 507 mounted on the insertion rod 506. The ball bearing 507 contacts the surface of the tissue paper, transforming traditional sliding friction into rolling friction, significantly reducing wear on the tissue paper surface. This is especially effective for soft tissues or easily fuzzy rolls, preventing edge wear and fuzzing. The locking rod 503 has a cross-shaped structure at one end near the baffle 504 and a circular structure at the other end away from the baffle 504. Both the locking rod 503 and the sliding rod 505 are located on the side of the baffle 504 away from the insertion rod 506, with the baffle 504 having a larger diameter than the insertion rod 506. The locking rod 503 and the sliding rod 505 form a double-support structure from both sides of the baffle 504, slidingly connected to the box body 3. This effectively prevents the baffle 504 from tilting during adjustment or use, further ensuring centering accuracy.

[0023] As a technical optimization of this utility model, a sealing mechanism 1 is installed on the top of the box body 3. The sealing mechanism 1 includes a support plate 101 and a placement groove 102. The support plate 101 is installed on the top of the box body 3. The top of the support plate 101 is provided with a placement groove 102. The support plate 101 is arranged in an L-shaped structure. Two locking blocks 103 are symmetrically fixedly connected to the side wall of the support plate 101. A non-stick adhesive clip 104 is installed on the locking block 103. The protective film of the non-stick adhesive clip 104 is removed and pasted on the wall. Then the fixing locking block 103 on the side wall of the support plate 101 is locked into the non-stick adhesive clip 104. The overall fixation of the tissue box can be achieved to prevent it from sliding during use.

[0024] As a technical optimization of this utility model, a limiting mechanism 2 is fixed on the support plate 101. The limiting mechanism 2 includes a limiting frame 201 and a stop block 204. Two limiting frames 201 are symmetrically fixedly connected to the bottom end of the support plate 101. A connecting shaft 203 is fixedly installed on the limiting frame 201, and the stop block 204 is rotatably connected to the connecting shaft 203. Both sides of the box body 3 are provided with slots 205. By aligning the limiting frames 201 on both sides with the slots 205 of the box body 3 and sliding the box body 3, the limiting frames 201 are completely located in the slots 205, thereby restricting the lateral movement of the support plate 101. The body 3 is engaged with the limiting frame 201. The limiting frame 201 is located in the slot 205. A card plate 202 is fixedly installed on the part of the body 3 near the slot 205. The card plate 202 is L-shaped and engaged with the limiting frame 201. The abutment block 204 is rotatably connected to the card plate 202. After the limiting frame 201 is engaged, the abutment block 204 rotates around the connecting shaft 203, so that the abutment block 204 is in contact with the horizontal section of the card plate 202 fixed on the body 3. The longitudinal position of the support plate 101 and the body 3 is fixed by friction, preventing the support plate 101 from falling upward.

[0025] In use, when placing new tissues or adjusting the position of existing tissues, first open the tissue box to expose the internal structure. Hold the rotating rod 501 and rotate it according to the width of the tissues. Since the rotating rod 501 and the sliding rod 505 are connected by a thread, the rotation of the rotating rod 501 will cause the sliding rod 505 to slide linearly along the fixed rod 502. During the movement of the sliding rod 505, the baffle 504 connected to it will also move synchronously. The rotating rods 501 on both sides need to rotate synchronously to ensure that the baffles 504 on both sides are adjusted symmetrically until the distance between the baffles 504 is adapted to the width of the tissues. The baffles 504 on both sides are adjusted synchronously and move from both sides. Symmetrical forces are applied to the ends, effectively preventing the tissue from shifting within the box 3, ensuring smooth tissue extraction without jamming or clogging the tissue tray 4. When the tissue is placed inside the box 3, its sides contact the ball bearings 507 at the ends of the insert rods 506 on the side baffles 504. The ball bearings 507 on the insert rods 506 contact the tissue surface, transforming traditional sliding friction into rolling friction. This significantly reduces wear on the tissue surface, especially for soft tissues or easily fuzzy rolls. The ball bearings 507 effectively prevent edge wear and fuzzing, maintaining the tissue's appearance and performance, and extending its lifespan. Simultaneously, the locking lever 503 and the sliding lever 505 form a double support structure from both sides of the baffle 504, slidingly connected to the box body 3, effectively preventing the baffle 504 from tilting during adjustment or use, further ensuring centering accuracy. The cross-shaped structure design of the locking lever 503 near the baffle 504 enhances the connection strength with the baffle 504, avoiding breakage after long-term use. When it is necessary to take out paper towels, pinch one end of the paper towel from the paper tray 4 and pull it outwards gently. As the pulling force increases, the paper towel breaks, completing the paper dispensing process. When installing the support plate 101, align the two limiting brackets 201 on both sides with the locking slots 20 on the box body 3. 5. Slide the box 3 so that the limiting frame 201 is fully positioned in the slot 205, thereby restricting the lateral movement of the support plate 101. After the limiting frame 201 is engaged, rotate the abutment 204 around the connecting shaft 203 so that the abutment 204 is in contact with the horizontal section of the fixed plate 202 on the box 3. The friction force fixes the longitudinal position of the support plate 101 and the box 3, preventing the support plate 101 from falling upward. Finally, remove the protective film of the adhesive clip 104 and stick it on the wall. Then, engage the fixing clip 103 on the side wall of the support plate 101 into the adhesive clip 104 to achieve overall fixation of the tissue box and prevent it from sliding during use.
