Description

Technical Field

[0001] The utility model relates to the technical field of building block toys, in particular to a universal joint for splicing building blocks. Background Art

[0002] The universal joint of the splicing building block is a highly engineered connecting element, and its core purpose is to provide a connection point with multiple degrees of freedom, so that each building block can be combined and fixed in almost infinite directions and angles.

[0003] When many universal joints are subjected to rotational operations, they are prone to loosening, which causes them to be unable to effectively maintain the preset connection angle. This problem is particularly prominent when constructing complex and delicate building block models, because in these cases, precise angle control and stability are key elements for successful construction. Loose universal joints may lead to the instability of the entire structure and even cause the detachment of some components, thus affecting the aesthetics and overall structural firmness of the model. Summary of the Invention

[0004] To solve the above technical problems, the utility model provides a universal joint for splicing building blocks.

[0005] The utility model is realized by the following technical solutions: A universal joint for splicing building blocks includes a central shaft body. Four corners of the outer surface of the central shaft body are fixedly connected with upper support plates. The lower surface of the upper support plate is fixedly connected with a first bearing, and the surface of the first bearing is fixedly connected with a first locking disc.

[0006] Through the above technical solution, the central shaft body is the core part of the entire universal joint and plays a role in connecting various components. The upper support plates are fixedly connected to the four corners of its outer surface. These support plates provide multiple connection points. The combination of the first bearing and the first locking disc not only allows free rotation but also can lock the position when needed to ensure the structural stability.

[0007] As a further improvement of the above solution, a number of holes are opened on the outer surface of the first locking disc, and a fitting sleeve is fixedly connected to the lower surface of the first locking disc.

[0008] Through the above technical solution, through the fitting sleeve, it is easier to fix the universal joint on other building block components, and it is also convenient for disassembly, improving the reusability.

[0009] As a further improvement of the above solution, the inner wall of the fitting sleeve is provided with threads, and a second locking disc is fixedly connected to the lower surface of the fitting sleeve.

[0010] Through the above technical solution, the threaded design on the inner wall of the fitting sleeve is designed to achieve a quick and stable connection with other building block components. This design allows users to firmly fix other building block components on the universal joint through a simple rotation action. At the same time, the adoption of threaded connection ensures accurate alignment during the connection process and stability after connection, effectively preventing loosening caused by external forces.

[0011] As a further improvement of the above solution, a second bearing is fixedly connected to the lower surface of the second locking disc, and a lower support plate is fixedly connected to the lower surface of the second bearing.

[0012] As a further improvement of the above solution, the lower support plate is fixedly connected to the outer surface of the central shaft body, and a limit pin is inserted into the surface of the first locking disc.

[0013] Through the above technical solution, by adjusting the position of the limit pin, users can limit the rotation angle of the locking disc as needed, thereby locking and fixing the angle of the building blocks.

[0014] As a further improvement of the above solution, a positioning hole is provided inside the central shaft body.

[0015] As a further improvement of the above solution, one end of the limit pin is inserted into the positioning hole.

[0016] Through the above technical solution, inserting the limit pin into the positioning hole can limit the rotation angle of the locking disc, preventing the locking disc from continuing to rotate along the bearing, thereby limiting and fixing the angle of the building block assembly.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] By providing a fitting sleeve, the present utility model allows the fitting sleeve to achieve multi-directional rotation through the free rotation of the first bearing and the second bearing, thereby adapting to multi-directional connection and construction of building blocks, enhancing the creative space and possibilities of building block construction. At the same time, by using the cooperation of the limit pin and the positioning hole, personnel can pass the limit pin through and insert it into the positioning hole inside the first locking disc, thereby restricting the rotational freedom of the bearing and the rotation angle of the locking disc. Users can accurately control and fix the angle of the building block components according to actual needs, which is particularly important when constructing complex structures or models that require specific angles.

[0025] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination can be formed between the following described embodiments or technical features to form a new embodiment. Embodiment

[0026] Please combine Figures 1-4 , a universal joint for a splicing block of the present embodiment includes a central shaft body 1. At the four corners of the outer surface of the central shaft body 1, upper support plates 2 are fixedly connected. The lower surface of the upper support plate 2 is fixedly connected with a first bearing 3. The surface of the first bearing 3 is fixedly connected with a first locking disc 4. When the position does not need to be locked, the first bearing 3 allows the block components connected thereto to rotate freely, thereby realizing multi-directional connection and construction. When a certain position or angle needs to be fixed, the first locking disc 4 can be fixed at a specific position through the limit pin 9, thereby restricting the rotational freedom of the bearing and ensuring the stability of the structure.

[0027] A number of holes are provided on the outer surface of the first locking disc 4. The lower surface of the first locking disc 4 is fixedly connected with a fitting sleeve 5. Through the design of the fitting sleeve 5, it is not only convenient to fix the universal joint on other block components, but also convenient for disassembly. Users can flexibly perform assembly and disassembly operations according to needs, improving the reusability and flexibility of the block system.

[0028] Internal threads are provided on the inner wall of the fitting sleeve 5. The lower surface of the fitting sleeve 5 is fixedly connected with a second locking disc 6. The thread design on the inner wall of the fitting sleeve 5 allows users to achieve quick and precise connection with other block components through rotational movement. At the same time, the adoption of threaded connection ensures precise alignment during the connection process and stability after connection, effectively preventing loosening caused by external forces.

[0029] The lower surface of the second locking disc 6 is fixedly connected with a second bearing 7. The lower surface of the second bearing 7 is fixedly connected with a lower support plate 8.

[0030] The lower support plate 8 is fixedly connected to the outer surface of the central shaft body 1. A limit pin 9 is inserted into the surface of the first locking disc 4. The limit pin 9 is inserted into the surface of the first locking disc 4. By adjusting the position of the limit pin 9, the user can limit the rotation angle of the locking disc as needed, so as to achieve precise control and fixation of the angle of the building block.

[0031] A positioning hole 10 is formed inside the central shaft body 1.

[0032] One end of the limit pin 9 is inserted into the positioning hole 10. Inserting the limit pin 9 into the positioning hole 10 can limit the rotation angle of the locking disc, so that the locking disc will not continue to rotate along the bearing, thereby limiting and fixing the angle of the building block assembly.

[0033] The implementation principle of a universal joint for a splicing building block in the embodiment of the present application is as follows: A person fixedly connects four upper support plates 2 to the corresponding four corners of the outer surface of the central shaft body 1 to ensure their stability. A first bearing 3 is fixedly connected to the lower surface of the upper support plate 2 to closely combine it with the upper support plate 2. A first locking disc 4 is fixedly connected to the surface of the first bearing 3. At this time, the first bearing 3 allows the building block assembly connected thereto to rotate freely. A fitting sleeve 5 is fixedly connected to the lower surface of the first locking disc 4. Note that its inner wall is provided with threads for subsequent connection with other building block components. A second locking disc 6 is fixedly connected to the lower surface of the fitting sleeve 5. This step is to increase the connection stability. A second bearing 7 is fixedly connected to the lower surface of the second locking disc 6 to ensure its firm combination with the second locking disc 6. The lower support plate 8 is fixedly connected to the outer surface of the central shaft body 1 to form the bottom support of the entire universal joint. When it is necessary to fix a certain position or angle, the first locking disc 4 can be fixed at a specific position through the limit pin 9, thereby restricting the rotational freedom of the bearing and ensuring the stability of the structure. The rotation angle of the locking disc is restricted, and it is ensured that one end of the limit pin 9 is inserted into the positioning hole 10 inside the central shaft body 1. In this way, the rotation of the locking disc can be further restricted, and precise control and fixation of the angle of the building block can be achieved. The user can effectively use this universal joint for splicing building blocks to achieve multi-directional connection and construction, and can also be fixed at a specific position or angle as needed to ensure the stability and flexibility of the building block structure.

[0034] The above-mentioned implementation manners are only the preferred implementation manners of the present utility model, and cannot be used to limit the scope of protection of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model belong to the scope required to be protected by the present utility model.
