They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 8 As shown, this application embodiment provides a cross-shaped ring frame, including a central block 1, four beams 2, and multiple inserts 3. The central block 1 has four side end faces 11, which are arranged sequentially around the circumference of the central block 1. Each side end face 11 is provided with a slot 12, and a slot 4 is provided in the center of the central block 1. Each of the four beams is provided with a tongue 21 at one end, and the tongues 21 of the four beams 2 can be inserted into the corresponding slots 12. Each beam 2 and the central block 1 are located in the same plane. A slot 4 is provided at the end of each beam 2 facing away from the central block 1, and each insert 3 can be inserted into the corresponding slot 4.

[0024] The cross-shaped ring toss frame provided in this application consists of a central block 1 and four beams 2 that can be plugged together for support at the bottom. The inserts 3 are also detachably connected to the central block 1 and the four beams 2, and after assembly, all beams 2 and the central block 1 are located in the same plane. This ensures that the cross-shaped ring toss frame is stable and does not wobble when placed on a flat surface after assembly, resulting in even force distribution during ring tossing, improved accuracy, and a better user experience. Furthermore, the central block 1 and the four beams 2 are connected by plugging, allowing each part to be manufactured separately. The entire device is easy to disassemble, and the disassembled components can be stacked for easy carrying, mailing, and storage.

[0025] Furthermore, since all components of the cross ring toss frame in this application are detachable and connectable, they can be freely combined as needed, increasing the diversity and playability of the game, and making it easier for parents and children to operate together, thus enhancing the fun of parent-child interaction.

[0026] In one possible implementation, the inner wall of the slot 12 is provided with a protrusion 121, and the outer wall of the tongue 21 has a recess 211. When the tongue 21 is inserted into the recess 211, the protrusion 121 is embedded in the recess 211. The cooperation between the protrusion 121 and the recess 211 increases the connection strength between the tongue 21 and the slot 12, making the connection between the four beams 2 and the central block 1 more stable and improving the overall stability of the cross-shaped ring frame. Simultaneously, the cooperation between the protrusion 121 and the recess 211 also serves as a limiting function, making the position of the four beams 2 on the central block 1 more accurate, further improving the accuracy of the ring setting.

[0027] The central block 1 and the four beams 2 can be made of materials such as plastic and wood. When they are inserted, the protrusion 121 and the recess 211 can deform to a certain extent. After the insertion is completed, the deformation is restored, making the insertion convenient and firm.

[0028] In one possible implementation, the protruding portion 121 includes an outwardly convex arcuate surface extending along the thickness direction of the central block 1, and the recessed portion 211 includes an inwardly concave arcuate surface extending along the thickness direction of the beam body 2. When the tongue 21 is inserted into the slot 12, the outwardly convex arcuate surface conforms to the inwardly concave arcuate surface. The design of the outwardly convex and inwardly concave arcuate surfaces provides a guiding effect, making the insertion process smoother, reducing friction and resistance, and facilitating quick and accurate assembly by the user. Furthermore, the arcuate surface design also provides a certain degree of elasticity, making insertion and removal smoother.

[0029] In one possible implementation, the beam 2 has a main beam 22, with end walls 221 at both ends along its length. A tongue 21 is located at the center of the end wall 221, with a gap between the tongue 21 and the peripheral edge of the end wall 221. A slot 12 is also located at the center of the side end face 11 of the middle block 1, with a gap between it and the peripheral edge of the side end face 11. Thus, after the middle block 1 and the beam 2 are inserted, the end wall 221 and the side end face 11 fit together, creating a limiting effect and preventing the beam 2 from easily tilting.

[0030] In one possible implementation, the central block 1 includes an upper housing 101 and a lower housing 102, which are interlocked, forming slots 12 between them. The design of the upper housing 101 and lower housing 102 makes the slot 12 structure of the central block 1 more robust and easier to manufacture. After the upper housing 101 and lower housing 102 are interlocked, they are connected by fasteners, further enhancing the structural strength of the central block 1.

[0031] In one possible implementation, the lower housing 102 has a lower plate and four first protrusions 1021 disposed at the four corners of the lower plate, the first protrusions 1021 extending along the thickness direction of the lower plate. The upper housing 101 has an upper plate and four second protrusions 1011 disposed at the four corners of the upper plate, the second protrusions 1011 extending along the thickness direction of the upper plate. When the upper housing 101 and the lower housing 102 are engaged, the four first protrusions 1021 abut against the second protrusions 1011 respectively, and fasteners pass through the first protrusions 1021 and are connected to the second protrusions 1011. Through the abutting engagement of the first protrusions 1021 and the second protrusions 1011, the connection area between the upper housing 101 and the lower housing 102 is increased, making the connection between the upper housing 101 and the lower housing 102 more stable. Meanwhile, the fastener passes through the first boss 1021 and connects to the second boss 1011, further enhancing the connection strength between the upper housing 101 and the lower housing 102, and improving the overall stability and service life of the cross ring frame.

[0032] The card protrusion 121 is provided on the facing surfaces of adjacent first protrusion 1021 and adjacent second protrusion 1011.

[0033] In one possible implementation, the first boss 1021 includes a first enclosure 10211 and a first cylindrical column 10212. The first enclosure 10211 is vertically connected to the lower plate, and the first cylindrical column 10212 is located inside the first enclosure 10211 and vertically connected to the lower plate. The first cylindrical column 10212 is connected to the first enclosure 10211 by a plurality of reinforcing ribs 5. The lower housing 102 has a through hole 1022, which penetrates the first cylindrical column 10212. The second boss 1011 includes a second enclosure 10111 and a second cylindrical column 10112. The second enclosure 10111 is vertically connected to the lower plate, and the second cylindrical column 10112 is located inside the second enclosure 10111 and vertically connected to the lower plate. The second cylindrical column 10112 has a threaded groove and is connected to the second enclosure 10111 by a plurality of reinforcing ribs 5. One end of the fastener passes through the through hole 1022 and is threaded into the threaded groove, while the other end of the fastener is confined within the lower housing 102. The threaded connection ensures a secure installation and facilitates disassembly and assembly should problems arise. The first retaining wall 10211 and the second retaining wall 10111 provide a support for the locking protrusion 121 and also act as reinforcing ribs 5, increasing the strength of the middle block 1. Furthermore, the alignment of the first retaining wall 10211 and the second retaining wall 10111 increases the contact area, ensuring a smooth and stable connection between the upper housing 101 and the lower housing 102. The reinforcing ribs 5 further enhance the overall strength of the middle block 1.

[0034] In one possible implementation, one of the first enclosure 10211 and the second enclosure 10111 is provided with a rod 10213, and the other with a sleeve 10113. When the upper housing 101 and the lower housing 102 are engaged, the rod 10213 is inserted into the sleeve 10113. The cooperation between the rod 10213 and the sleeve 10113 further enhances the connection stability between the upper housing 101 and the lower housing 102, preventing loosening or separation during use, thus ensuring the overall stability and service life of the cross ring frame. Simultaneously, the design of the rod 10213 and the sleeve 10113 simplifies the installation process of the upper housing 101 and the lower housing 102, allowing for initial positioning and enabling users to complete assembly more conveniently and quickly.

[0035] In one possible implementation, the inner wall of each slot 4 is provided with multiple ribs 41, each rib 41 having an outwardly convex arc surface. The ribs 41 extend along the extension direction of the slot 4, and are arranged at intervals around the circumference of the slot 4. When the insert 3 is inserted into the slot 4, the outer wall of the insert 3 fits against the ribs 41. The design of the ribs 41 increases the friction between the insert 3 and the slot 4, making the insert 3 more stable within the slot 4 and less prone to falling out. Simultaneously, the outwardly convex arc surface of the ribs 41 also serves as a guide, making the insertion of the insert 3 into the slot 4 smoother, reducing friction and resistance, and improving assembly efficiency. Furthermore, the ribs 41 enhance the structural strength of the slot 4, improving the overall durability of the cross-shaped ring frame.

[0036] In one possible implementation, each of the slots 4 is a blind slot. The blind slot design seals the bottom of the slot 4, preventing dust, debris, and other contaminants from entering the slot 4, ensuring its cleanliness. It also prevents the insertion post 3 from being interfered with by external factors during insertion, improving the accuracy and stability of the connection. Furthermore, the blind slot design simplifies the manufacturing process of the slot 4 and reduces production costs.

[0037] The preferred embodiments disclosed above are merely illustrative of this application. These preferred embodiments do not exhaustively describe all details, nor do they limit the application to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
