[0002] As a commonly used household item, storage racks are widely used in places such as homes, offices, and stores. Traditional storage racks mostly adopt fixed structures, which results in larger packaging sizes during transportation, thus increasing logistics costs. In addition, there are also some storage rack products on the market that adopt disassembly and assembly designs. Although the packaging sizes of such products are smaller, the assembly and disassembly processes are relatively cumbersome. Special tools and a long time are often required to complete the assembly, which brings inconvenience to users. In addition, traditional storage racks are prone to shaking and instability problems during use, affecting the user experience.

[0003] In recent years, with the increasing demand for the convenience and flexibility of household items, various storage rack products that are easy to assemble and disassemble have emerged on the market. These products usually adopt quick-connection structures to simplify the assembly process, but most connection structures still have certain limitations. For example, there are many parts, and it is difficult for users to distinguish different parts during installation, resulting in difficult assembly. Moreover, many users report that even if they spend a lot of time, they often cannot complete the assembly smoothly due to improper assembly, which is one of the biggest pain points for customers in this type of product on the market. Most importantly, the structures adopted by related products on the market have insufficient connection strength at the connection parts, and are prone to problems such as shaking and loosening, seriously affecting the stability and service life of the storage rack. The connection strength is not high enough, and it is easy to loosen after long-term use, affecting the stability of the storage rack; the connectors are prone to being exposed, which not only affects the aesthetics but also may pose a safety hazard.

[0035] Referring to Figures 1 to 6 , a rotary locking connection device, comprising:

[0036] A rotating member 110;

[0037] A first clamping member 100, rotatably mounted at one end of the rotating member 110, and a first mounting portion 130 is provided at the end of the first clamping member 100, and the first mounting portion 130 is an uneven structure;

[0039] Wherein, the first clamping member 100 and the second clamping member 120 can be inserted and locked in opposite directions through the first mounting portion 130 and the second mounting portion 140.

[0040] By setting the structures of the rotating member 110, the first engaging member 100, and the second engaging member 120, a simple and fast assembly method is achieved, reducing the user's confusion during the installation process and making the installation process more convenient; the concave-convex structures of the first installation portion 130 and the second installation portion 140 match each other, and through the method of inserting and locking in opposite directions, the stability and load-bearing capacity of the connection part are ensured, thus improving the connection strength; by designing the mutual engaging structure of the first engaging member 100 and the second engaging member 120, the problem of ugliness caused by the exposure of the connecting member is avoided, enhancing the overall aesthetics of the product; the first engaging member 100 and the second engaging member 120 are precisely docked through the corresponding concave-convex structures, improving the stability of the connection part and making the overall structure more durable; the design of the rotating member 110 enables the first engaging member 100 and the second engaging member 120 to be adjusted in multiple directions, enhancing the flexibility and adaptability of the connecting device.

[0041] Referring to Figure 3 and Figure 4 , the first installation portion 130 is provided with a first sliding groove 150, the second installation portion 140 is provided with a second sliding groove 160, the rotating member 110 is provided with a first rotating shaft 180 and a second rotating shaft 190, the first rotating shaft 180 is slidably installed in the first sliding groove 150, and the second rotating shaft 190 is slidably installed in the second sliding groove 160. By setting the first sliding groove 150 and the second sliding groove 160, and the first rotating shaft 180 and the second rotating shaft 190 that match them, the first engaging member 100 and the second engaging member 120 can slide and overlap on the rotating member 110, and finally the first engaging member 100 and the second engaging member 120 can be overlapped into a plate-like structure, greatly reducing the volume and facilitating transportation and storage. The first engaging member 100 and the second engaging member 120 can move freely in multiple directions, enhancing the flexibility of the connecting device and adapting to more different application scenarios.

[0042] Referring to Figure 5, one end of the rotating member 110 is provided with an extension portion 170, the second rotating shaft 190 is arranged on the extension portion 170, and the extension portion 170 is adapted to limit the rotation angles of the first clamping member 100 and the second clamping member 120. It can be understood that the rotating member 110 can be integrally designed in an "L" shape. The rotating member 110 enables the connecting device to achieve multi-angle adjustment in a limited space, improving the space utilization efficiency. The "L" shape design not only improves the overall stability of the connecting device, but also further enhances the supporting force of the second rotating shaft 190 through the design of the extension portion 170, ensuring the firmness of the connecting part. The design of the extension portion 170 increases the rotation radius of the second clamping member 120, making the rotation amplitude larger, so as to facilitate the stacking of the first clamping member 100 and the second clamping member 120, and is convenient for transportation and storage. The rotating member 110 designed in an "L" shape improves the flexibility and application range of the first clamping member 100 and the second clamping member 120.

[0043] Refer to Figure 4 , the first clamping member 100 and the second clamping member 120 are cavity-type structures with one end open. After the first clamping member 100 and the second clamping member 120 are inserted and locked facing each other, an installation cavity is formed, and the rotating member 110 is arranged in the installation cavity. It can effectively wrap the rotating member 110, thereby enhancing the structural stability of the connecting part. The design of the cavity-type structure can hide the rotating member 110, avoiding the problem of exposed connecting parts and improving the overall aesthetics of the product.

[0044] Refer to Figure 5 , the rotating member 110 is a single-axis rotating member or a multi-axis rotating member. The multi-axis rotating member can be one of a double-axis rotating member, a three-axis rotating member or a four-axis rotating member. The design of the rotating member 110 with different numbers of axes can meet the requirements of rotation angles and directions in different application scenarios, improving the application range of the connecting device. The design of the multi-axis rotating member 110 can provide more support points, thereby improving the stability of the connecting device. The rotating member 110 designed with a multi-axis makes the connecting device more reliable during use, reducing potential unstable factors caused by single-axis rotation.

[0045] The first clamping member 100 includes a first protrusion and a first recess, the second clamping member 120 includes a second protrusion and a second recess. The first protrusion is clamped in the second recess, and the second protrusion is clamped in the first recess. Locking structures 200 are respectively arranged on the first protrusion and the second protrusion, and the locking structures 200 are used to fix the first clamping member 100 and the second clamping member 120 to each other. The locking structures 200 on the first protrusion and the second protrusion ensure the firm fixation between the first clamping member 100 and the second clamping member 120, enhancing the stability of the connecting device. The locking mechanism of the interlocking structure ensures the reliability and durability of the connecting device during use.

[0046] The locking structure 200 is one of a cantilever structure, an annular snap structure, a torsion snap structure, a ball screw structure or a snap lock structure. By adopting different types of locking structures 200, the exposure of the connecting piece is avoided, and the overall aesthetics of the product is improved. Different types of locking structures 200 provide a reliable locking mechanism, ensuring the reliability and durability of the connecting device during use.

[0047] Referring to Figure 2 , on the side wall of the first clamping member 100 away from the first mounting portion 130, a first clamping portion 210 is provided. On the side wall of the second clamping member 120 away from the second mounting portion 140, a second clamping portion 220 is provided. The first clamping portion 210 is adapted to clamp the first clamping member 100 to the pipe rack, and the second clamping portion 220 is adapted to clamp the second clamping member 120 to the pipe rack. By providing the first clamping portion 210 and the second clamping portion 220, a reliable connection between the connecting device and the pipe rack is ensured, reducing the unstable factors caused by loosening. The design of the clamping portion enables the connecting device to closely fit the pipe rack, reducing the occupied space and improving the space utilization rate. It can be understood that the first clamping portion 210 and the second clamping portion 220 can be set as circular arc notches, and a fixing portion adapted to the circular arc notches is provided at the end of the pipe rack, so as to facilitate the clamping of the first clamping portion 210 and the second clamping portion 220 at the fixing portion of the pipe rack.

[0048] It can be understood that the first clamping member 100 and the second clamping member 120 can be made of metal materials. When the first clamping member 100 and the second clamping member 120 are made of metal materials, when the first clamping member 100 and the second clamping member 120 are installed on the pipe rack, they can be connected by spot welding. The first clamping member 100 and the second clamping member 120 can also be made of nylon or plastic materials. When installing the first clamping member 100 and the second clamping member 120, an adhesive, such as glue, can be applied to the side walls of the first clamping member 100 and the second clamping member 120, so as to ensure the stable installation of the first clamping member 100 and the second clamping member 120 to the pipe rack. This design can reduce welding, thereby reducing the labor intensity of workers and improving efficiency. Arc transition structures are provided at the edges of the first mounting portion 130 and the second mounting portion 140. The arc transition structures make it easier for the first mounting portion 130 and the second mounting portion 140 to be aligned and clamped, simplifying the assembly process and improving the assembly efficiency. The arc transition structures can disperse stress and reduce stress concentration, thereby improving the structural strength and durability of the connecting device.

[0049] The storage rack according to the second aspect embodiment of the present utility model includes a plurality of pipe racks, and the plurality of pipe racks are sequentially connected by a rotary locking connection device according to the first aspect embodiment.

[0050] The storage rack according to the embodiment of the present utility model has at least the following beneficial effects: By adopting the rotary locking connection device of the present utility model, multiple pipe racks can be quickly and simply connected together, simplifying the assembly process and improving the assembly efficiency; the structural design of the rotary locking connection device ensures a firm connection between the pipe racks and improves the overall stability of the storage rack; the rotary locking connection device of the present utility model can adapt to different connection requirements, enabling the storage rack to adjust its shape and size according to actual needs and enhancing flexibility; through the design of hiding the connecting parts, the exposed connecting parts are avoided from damaging the overall aesthetics, and the overall aesthetics of the product is improved; through an efficient connection method, a compact structural layout can be achieved, improving the space utilization rate; since the storage rack adopts a detachable connection method, it is convenient to disassemble and reassemble, and is convenient for transportation and storage.

[0051] In the embodiment of the first aspect, referring to Figure 1 , the first clamping part 100 and the second clamping part 120 are in a locked state. At this time, the first mounting part 130 of the first clamping part 100 is clamped with the second mounting part 140 of the second clamping part 120 and is fixed by a locking structure 200 such as a cantilever structure, a wave bead screw structure or a snap-locking structure. When the user needs to separate the first clamping part 100 and the second clamping part 120, the locking structure 200 needs to be released first, and the first clamping part 100 and the second clamping part 120 are separated by force. At this time, the locking structure 200 is released, and the first clamping part 100 and the second clamping part 120 can be separated from each other. After separation, the first clamping part 100 and the second clamping part 120 are as Figure 2 shown. At this time, both the first clamping part 100 and the second clamping part 120 can rotate around the rotating part 110. The user can continue to rotate the first clamping part 100 and the second clamping part 120 until they can be stacked together to form a flat plate-like structure, greatly reducing the occupied space and facilitating transportation and storage. The stacked state of the first clamping part 100 and the second clamping part 120 can refer to Figure 3 's state.

[0052] It can be understood that one end of the first clamping part 100 is used to lock with the second clamping part 120, and the other end is used to fix with the pipe rack; similarly, one end of the second clamping part 120 is used to lock with the first clamping part 100, and the other end is used to fix with another pipe rack. By sequentially connecting multiple pipe racks using the first clamping part 100 and the second clamping part 120, a continuous long pipe can be formed. This design enables the pipe racks to be folded through the connection device during logistics transportation, thus greatly saving transportation space; after the user receives the goods, they can easily unfold and use them.

[0053] The pipe rack is a metal part with openings at both ends. Its shape can be cylindrical, square, oval or egg-shaped. To match the shape of the pipe rack, the outer contours of the first clamping part 100 and the second clamping part 120 can be adaptively modified according to the specific shape of the pipe rack, as long as it can ensure that the first clamping part 100 and the second clamping part 120 can be smoothly inserted into the pipe rack. It can be understood that the pipe rack can also be made of wood, and the wood product is designed with hollow at both ends to facilitate the installation of the first clamping part 100 and the second clamping part 120. In some embodiments, the pipe rack can also be a plastic part, and the pipe rack can be selected according to different material and design requirements.

[0054] Referring to Figure 1 , the first clamping part 100 and the second clamping part 120 are in a locked state. When the user needs to separate the first clamping part 100 and the second clamping part 120, only need to apply force to separate the two clamping parts. After separation, the clamping parts are as shown in Figure 2 . At this time, both the first clamping part 100 and the second clamping part 120 can rotate around the rotating part 110. After the first clamping part 100 and the second clamping part 120 rotate a certain angle, they can be stacked together to form a flat structure, thus greatly reducing the logistics transportation cost.

[0055] Referring to Figure 6 , in the embodiments of the second aspect, the pipe rack and the rotary locking connection device are applied to the storage rack. During logistics transportation, the long pipe racks in the storage rack are connected by the rotary locking connection device; the pipe racks can be folded for transportation; after the user receives the goods, they can be directly opened for use without using additional tools for assembly, and the installation process is simple, thus improving the user satisfaction.

[0056] The above has described the embodiments of the present utility model in detail with reference to the drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
