Description

Technical Field

[0001] The utility model relates to the field of center drawers, in particular to the technical field of center drawer boxes, and specifically refers to a square paper box for center drawers. Background Art

[0002] As people's living standards improve, they pay more and more attention to the convenience of daily necessities. Nowadays, the center-drawn single-sheet paper box has been widely used in places such as sanitary napkins. The principle of the single-sheet center-drawn box is to let the center draw out a single sheet in a winding manner. While winding, it will pass through a smaller and smaller paper outlet, using the friction resistance and deformation resistance of the paper to pull out the next sheet of paper while breaking the paper.

[0003] However, the current center-drawn single-sheet paper box has the following problems: when the center paper is drawn out, the outer edge paper will collapse and stack toward the center under the action of gravity because there is no support. When multiple layers of paper are stacked together, the paper outlet will be blocked, resulting in single-sheet paper withdrawal being not smooth and unusable.

[0004] In this regard, the Chinese utility model patent with application number CN202021650544.X discloses a paper box that prevents the center drawer from sagging, which solves the above-mentioned problem. However, the paper box has a large horizontal length and occupies a large horizontal space. The arrangement of placing two center drawers at the same time increases the amount of center drawers, but it is also necessary to open the two box covers when replacing the center drawers, thereby increasing the workload. Therefore, center drawers with larger diameters are currently purchased, but there is currently a lack of paper boxes for storing larger center drawers. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a square paper box for a center drawer, which is used for storing a large center drawer and meets the needs.

[0006] The utility model is realized through the following technical scheme: a square paper box for center draw, comprising a box body, a cover body hinged to the box body and covering the opening of the box body, the box body comprising a bottom plate and a first square tube section fixedly connected to the bottom plate, the cover body comprising an end cover, and a second square tube section fixedly connected to the end cover and hinged to the first square tube section, the first square tube section and the second square tube section are connected at opposite end faces, and a plurality of reinforcing ribs are fixedly connected to the inner circumferential surfaces of the first square tube section and the second square tube section.

[0007] When the utility model is used, a larger paper box is required due to the enlargement of the center drawer, and the larger paper box is relatively weak in overall strength. Therefore, the strength of the paper box is improved by arranging the reinforcing ribs.

[0008] Preferably, the base plate is provided with support holes for screws to pass through, and the inner side surface of the base plate is also provided with transverse and longitudinal reinforcements arranged in a criss-cross pattern, as well as oblique reinforcements connecting the transverse reinforcements / longitudinal reinforcements and extending toward the inner side surface of the first square tube section, and reinforcing ribs arranged corresponding to the longitudinal reinforcements / transverse reinforcements / oblique reinforcements are connected to the corresponding longitudinal reinforcements / transverse reinforcements / oblique reinforcements.

[0009] This preferred solution enhances the strength of the bottom plate by providing transverse ribs, longitudinal ribs and oblique ribs, and at the same time, the reinforcing ribs are correspondingly connected to the longitudinal ribs / transverse ribs / oblique ribs, thereby further enhancing the overall strength of the box body.

[0010] Preferably, a support plate supporting the central drawer is fixedly connected to the bottom plate, and the first square pipe section is also provided with support ribs extending upward and supporting the support plate.

[0011] This preferred solution facilitates improving the supporting strength of the support plate by providing supporting ribs.

[0012] Preferably, an inwardly extending extrusion plate is fixedly connected to the inner side surface of the reinforcing rib located on the first square tube section, and the side surface of the extrusion plate close to the end cover is an inclined surface inclined outwardly and connected to the corresponding reinforcing rib.

[0013] When the preferred solution is in use, when the center drawer is placed in the box body, the center drawer is squeezed from the outer circumferential surface of the center drawer by the inclined surface, thereby facilitating the fixing of the center drawer in the box body.

[0014] Preferably, a first groove is further provided on the end face of the first square tube segment, and the groove extends to the inner circumferential surface of the first square tube segment; a first plug-in block adapted to and inserted into the first groove is fixedly connected to the end face of the second square tube segment; a limiting block extending to the bottom of the first plug-in block is fixedly connected to the side face of the reinforcing rib on the first square tube segment near the end cover; and a chamfer is provided at the corner of the limiting block near the first plug-in block.

[0015] In this preferred solution, the first groove and the limit block are provided to form a channel for inserting the first plug block, which not only plays a positioning role, but also enhances the connection strength between the first square tube section and the second square tube.

[0016] Preferably, the end cover is further provided with an observation hole located just below the paper outlet, and transparent glass is sealed and installed in the observation hole.

[0017] The preferred solution provides an observation hole to facilitate observation of the thickness of the center drawer in the box body, thereby facilitating timely replacement of the center drawer with a new one.

[0018] Preferably, the bottom plate is provided with a limiting convex plate inserted into the center drawer.

[0019] This preferred solution facilitates insertion into the center drawer by setting a limiting relief plate, thereby preventing the center drawer from sagging after a certain amount of use.

[0020] Preferably, two elastic plugs inserted into the first square tube section and arranged transversely are further provided on the inner circumferential surface of the second square tube section, the elastic plug is provided with a plug hole penetrating the elastic plug, the inner circumferential surface of the first square tube section is further provided with a second plug block inserted into the plug hole, the side of the second plug block close to the end cover is an inclined guide surface, the first square tube section is further provided with a through hole penetrating the first square tube section and arranged corresponding to the elastic plug, the through hole is located directly above the elastic plug, a key block is further provided directly above the through hole, and a protrusion inserted into the through hole and pressing the elastic plug is fixedly connected to the bottom surface of the key block.

[0021] When this preferred solution is also in use, the elastic insert follows the rotation of the second square tube segment and is inserted into the first square tube segment. When passing through the second insert block, under the guidance of the guide surface, the second insert block crosses over the second insert block below. Correspondingly, when the insertion hole is located directly below the second insert block, the second insert block is inserted into the insertion hole, thereby playing the role of positioning the insert, thereby improving the connection strength between the first square tube segment and the second square tube segment. At the same time, when the key block is used to insert the protrusion into the through hole and press the elastic insert downward, the elastic insert moves to the bottom of the second insert block, and at the same time, the end cover is pulled to separate the end cover from the cover body.

[0022] Preferably, a fixing block connected to the elastic plug is fixedly connected to the end cover.

[0023] This preferred solution facilitates enhancing the connection strength between the elastic insert and the cover body by disposing the fixing block.

[0024] Preferably, two guide plates are fixedly connected to the inner circumferential surface of the first square tube section, and a channel for inserting the elastic insert is formed between the two guide plates.

[0025] In this preferred solution, two guide plates are provided to provide a guiding function to the elastic insert.

[0026] The beneficial effects of the utility model are as follows: since the center drawer is enlarged, a larger paper box is required, and a large paper box is relatively weak in overall strength, so the strength of the paper box is improved by setting reinforcing ribs; the strength of the bottom plate is enhanced by setting transverse ribs, longitudinal ribs and oblique ribs, and at the same time the reinforcing ribs are correspondingly connected to the longitudinal ribs / transverse ribs / oblique ribs, thereby further enhancing the overall strength of the box body; when the center drawer is placed in the box body, the center drawer is squeezed from the outer circumferential surface of the center drawer by using the inclined surface, thereby facilitating the fixation of the center drawer in the box body.
