[0033] To enable those skilled in the art to better understand the technical solutions of this application, 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 the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Please refer to the following: Figures 1 to 9This embodiment provides a self-locking wooden box, including a box body 100 and a cover plate 200. The box body 100 has an internal cavity for storing items. Sliding planes 141 are provided on the top of the opposite side walls of the box body 100, and a locking groove is provided on the rear wall of the box body 100. The cover plate 200 slidably covers the top opening of the box body 100 via the sliding planes 141. A locking head is provided at the rear of the cover plate 200, so that the cover plate 200 slides on the sliding planes 141 and the locking head is inserted into the locking groove, thereby closing the box body 100. The locking head includes a first locking head 211 and a second locking head 212, which are arranged side-by-side at the rear of the cover plate 200. At least one gap 214 exists between the first locking head 211 and the second locking head 212, allowing the first locking head 211 and the second locking head 212 to be inserted together into the locking groove. The locking groove is used for limiting the movement so that when the first locking head 211 and the second locking head 212 are inserted into the locking groove together, the first locking head 211 and the second locking head 212 move closer to each other and elastically deform, thereby tightly locking into the locking groove. Specifically, the cover plate 200 has movable gaps on both sides of the root of the first locking head 211 and on both sides of the root of the second locking head 212. There is a gap 214 between the first locking head 211 and the second locking head 212. When the locking head is inserted into the locking hole 111, the first locking head 211 and the second locking head 212 move closer to each other under the force of the hole wall of the locking hole 111. The gap 214 between the first locking head 211 and the second locking head 212 decreases. At the same time, the first locking head 211 and the second locking head 212 are locked in the locking hole 111 by the force between them and the hole wall of the locking hole 111, thereby realizing the mutual locking of the cover plate 200 and the box 100.

[0035] As can be seen, the self-locking wooden box of this embodiment includes a box body 100 and a cover plate 200. The top of the two side walls of the box body 100 are provided with sliding planes 141, and a locking groove is provided on the rear wall of the box body 100. The cover plate 200 is slidably mounted on the top of the box body 100 via the sliding planes 141. A locking head is provided at the tail of the cover plate 200, so that the locking head can be inserted into the locking groove by sliding the cover plate 200 on the sliding planes 141, thereby locking and closing the opening of the box body 100. The top of the two side walls of the box body 100 are provided with sliding planes 141. The cover plate 200 is easy to slide on the box body 100. The rear wall of the box body 100 is provided with a locking groove, and the tail of the cover plate 200 is provided with a locking head. The locking head is inserted into the locking groove by sliding the cover plate 200 on the sliding plane 141. This solves the technical problem that existing wooden boxes cannot lock themselves and require the addition of padlocks and latches to lock, which leads to high costs. Moreover, the locking structure of this utility model is simple, does not require the use of many fastening screws and other parts, is easy to process and produce, is convenient for users to operate, and provides a good user experience.

[0036] It should be noted that the materials used in the wooden boxes mentioned in this application are not limited to wood, but also include bamboo, plastic and other materials.

With this configuration, when the locking head is inserted into the locking hole 111, the first protrusion 2110 and the second protrusion 2120 pass over the locking hole 111 and abut against the outer peripheral edge of the opening of the locking hole 111, making the locking structure more stable.

[0038] Specifically, the two side walls of the box body 100 are provided with slots 112, and the front two sides of the cover plate 200 are provided with latching protrusions 213 that cooperate with the slots 112. When the cover plate 200 slides onto the box body 100, the latching protrusions 213 engage with the slots 112. This design prevents the cover plate 200 from flipping over and damaging the locking head when the wooden box is inverted, thus improving safety and making it more convenient for users.

[0039] Furthermore, the cover plate 200 includes a first plate 210 and a second plate 220. The second plate 220 is stacked on the first plate 210 by bonding or screwing.

The front two sides of the first plate 210 protrude outward to form a first protrusion, and the front two sides of the second plate 220 protrude outward to form a second protrusion. The width of the first protrusion is greater than the width of the second protrusion, thus forming clip protrusions 213 on both sides of the front of the cover plate 200. The cover plate 200 adopts a double-layer setting, which makes its structure more stable and safer and more reliable for users. The clip protrusions 213 are formed in a simple and ingenious way, which is convenient for processing and production.

[0040] In this embodiment, a control groove 221 is provided on the upper front surface of the second plate 220 to control the cover plate 200 to slide on the box 100. By creating the control part by opening the control groove 221 on the upper front surface of the second plate 220, the flatness of the upper surface of the cover plate 200 is further ensured, which facilitates the transportation and storage of the product, and at the same time makes the appearance more beautiful.

[0041] Specifically, the housing 100 includes an outer panel 110, an inner panel 120, a lower bottom plate 130, and an upper partition 140. A locking groove is formed on the outer panel 110. The inner panel 120 is located inside the outer panel 110. The lower bottom plate 130 is located at the bottom of the outer panel 110. The upper partition 140 is located on the top of the inner panel 120. An opening is provided in the middle of the upper partition 140. The bottom of the inner panel 120 is connected to the outer panel 110 through the lower bottom plate 130. The top of the inner panel 120 is connected to the outer panel 110 through the upper partition 140. A sliding plane 141 is provided on the upper partition 140. A handle 160 is located on the outer side wall of the outer panel 110. The double-layer design of the outer panel 110 and the inner panel 120 further enhances the structural stability of the product and provides a better user experience.

[0042] Furthermore, the upper partition 140 protrudes circumferentially to form first connectors 142, and the upper part of the outer perimeter plate 110 is provided with first interfaces 113 spaced circumferentially. The upper partition 140 is inserted into the first interfaces 113 through the first connectors 142 to connect with the outer perimeter plate 110. The lower bottom plate 130 protrudes circumferentially to form second connectors 131, and the lower part of the outer perimeter plate 110 is provided with second interfaces 114 spaced circumferentially. The lower bottom plate 130 is inserted into the second interfaces 114 through the second connectors 131 to connect with the outer perimeter plate 110. With this configuration, the connection structure of the housing 100 is simple, easy to manufacture, and convenient to assemble. It also facilitates replacement and repair when a single part is damaged, making it convenient for users.

[0043] In this embodiment, the top of the inner panel 120 protrudes circumferentially to form a third connector 121, and the interior of the upper partition 140 is provided with a third interface 143 circumferentially spaced along the opening. The inner panel 120 is inserted into the third interface 143 through the third connector 121 to connect with the upper partition 140. The bottom of the inner panel 120 protrudes circumferentially to form a fourth connector 122, and the lower bottom plate 130 is provided with a fourth interface 132 opposite to the upper partition 140. The inner panel 120 is inserted into the fourth interface 132 through the fourth connector 122 to connect with the lower bottom plate 130. With this configuration, the entire housing 100 is assembled using a snap-fit ​​connection method, resulting in a simple and compact structure that eliminates the need for additional fastening components, facilitating manufacturing and assembly. The housing 100 is also relatively easy to assemble. Furthermore, it allows for easy disassembly, replacement, and repair when a single part is damaged, making it convenient for users.

[0044] Furthermore, the box body 100 also includes a middle partition 150, which is located in the middle of the inner enclosure panel 120 and is interference-fitted with the inner enclosure panel 120 to divide the internal space of the inner enclosure panel 120 into upper and lower parts. Alternatively, a snap-fit ​​structure can be used to install the middle partition 150 inside the box body 100. The middle partition 150 has several receiving holes, which facilitates users to store items that need to be fixed, such as glass wine bottles, making it convenient for users to use and providing a good user experience.
