[0001] This utility model belongs to the technical field of roof space frame structures, and in particular relates to a four-corner pyramid space frame assembly component. Background Technology

[0002] Four-corner pyramid space frames are widely used in various occasions, especially in events and buildings where aesthetics are paramount. In the exhibition and display industry, they can be used to construct booths, showrooms, and product display areas, providing exhibitors with a unique and aesthetically pleasing exhibition space. In sporting events, they can be used as grandstands, rest areas, and track coverings, providing a safe and comfortable environment for spectators and athletes.

[0003] A tetrahedral space frame consists of basic components such as top chords, bottom chords, web members, and ball joints, assembled through splicing. The resulting space frame comes in various types, primarily including: planar truss space frame systems, tetrahedral pyramidal space frame systems, and triangular pyramidal space frame systems. The splicing is tailored to different application scenarios. Due to site limitations and special requirements, the erection of the space frame needs to consider factors such as the height of the openwork layers and curved sections. The connecting rods between ball joints require adjustable lengths, and the adjustment and end fixing of these connecting rods are subject to stringent requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a four-corner pyramidal grid assembly component to solve the problems of relatively fixed length of connecting rods between existing ball nodes, small adjustment range, high assembly difficulty, and instability of the fixed points of ball nodes and connecting rods in the later stage.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A four-corner pyramidal space frame assembly component includes spherical nodes with a spherical structure;

[0007] Includes connecting pipes for connecting ball nodes;

[0008] The end of the connecting pipe is connected to the ball joint via a connector;

[0009] The ball node has multiple threaded holes evenly distributed on the spherical side. The connector is a tube structure with a stud fixed at one end for threaded connection with the threaded hole, and the other end is sleeved on the end of the connecting tube and fixed by a locking component.

[0010] Furthermore, the locking component includes a locking pin installed inside the connector port. The locking pin has a cylindrical structure with an arc-shaped protrusion at one end that extends through the side wall of the connector, and the other end is located inside the connector tube and is elastically supported by an elastic component. The side wall of the connector tube corresponding to the sleeve section is provided with positioning holes arranged in a row.

[0011] Furthermore, the locking pin is installed in a ring, and the side wall of the ring is provided with a bushing for the extension and retraction of the locking pin; the bottom of the locking pin has a limiting hole, and a limiting rod is fixed to the inner side wall of the ring for inserting into the limiting hole to limit movement; the limiting rod is sleeved with a tubular spring, and the ends of the spring are respectively supported on the locking pin and the inner side wall of the ring.

[0012] The locking pin and the ring are installed as a whole on the port side of the connector and are fixed by welding. A limit ring is sleeved and fixed on the port side of the connector.

[0013] Furthermore, a hexagonal prism-shaped rotating part is provided at the connection position between the connector and the stud.

[0014] This utility model has the following advantages: the corresponding round tube end of the connector is inserted into the connecting tube, and the fixing point between the connector and the connecting tube is determined by the telescopic action, and then fixed by the locking member. According to the telescopic cooperation between the connecting tube and the connector, it can adapt to the requirements of various installation specifications. The connecting tube of the same specification can be used for multiple purposes such as upper chord, lower chord, and web member. The connection end is threaded, allowing for disassembly and assembly. Compared with traditional welding-type fixing, it allows for later adjustment, reducing trial and error costs.

[0020] The components represented by each number in the attached diagram are listed below: ball joint 1, connecting pipe 2, connector 3, threaded hole 11, stud 31, locking pin 4, positioning hole 21, ring 5, bushing 51, limit rod 52, spring 6, limit ring 32, rotating part 33. Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1-4 As shown: A four-corner pyramid space frame assembly component, characterized in that:

[0023] Including spherical nodes 1, which have a spherical structure;

[0024] Includes connecting pipe 2 for connecting the ball nodes 1;

[0025] The end of the connecting pipe 2 is connected to the ball joint 1 by a connector 3;

[0026] The ball node 1 has multiple threaded holes 11 evenly opened on the spherical side. The connector 3 is a tube structure with a stud 31 fixed at one end for threaded connection with the threaded hole 11, and the other end is sleeved on the end of the connecting tube and fixed by a locking component.

[0027] During installation, ball joints at both ends need to be installed for mating. Based on the installation length of the connecting pipe, first install the corresponding connectors for both ball joints, aligning the stud end of the connector with the threaded hole of the ball joint, and then rotate the connector to secure it. Next, insert the corresponding round tube end of the connector into the connecting pipe, using the expansion and contraction mechanism to determine the fixing point between the connector and the connecting pipe, and then secure it with the locking mechanism. By adjusting the expansion and contraction fit between the connecting pipe and the connector, it can adapt to various installation specifications. Connecting pipes of the same specification can be used for multiple purposes such as upper chords, lower chords, and web members. The connection ends are threaded, allowing for disassembly and assembly, which allows for later adjustments compared to traditional welding fixation, reducing trial-and-error costs.

[0028] like Figure 2 As shown: The locking component includes a locking pin 4 installed inside the port of the connector 3. The locking pin 4 is a cylindrical structure with an arc-shaped protrusion at one end that extends through the side wall of the connector 3, and the other end is located inside the tube of the connector 3 and is elastically supported by an elastic component. The side wall of the corresponding sleeve section of the connecting tube 2 has positioning holes 21 arranged in a row. The side wall of the connector has through holes for the locking pin to pass through. When inserting the connector and the connecting tube, first press the locking pin into the connecting tube, then insert the locking pin into the end of the connecting tube with the positioning hole offset. After adjusting the connector to a suitable depth in the connecting tube, rotate the connector to align the locking pin with the corresponding positioning hole to complete the locking.

[0029] like Figure 3As shown: Locking pin 4 is installed in a ring 5. The side wall of ring 5 is provided with a bushing 51 for the extension and retraction of locking pin 4. Locking pin 4 has a limiting hole at its bottom. A limiting rod 52 is fixed to the inner wall of ring 5 for inserting into the limiting hole to limit movement. A tubular spring 6 is sleeved on the limiting rod 52, with the ends of the spring 6 supported on both the locking pin 4 and the inner wall of ring 5. When installing or adjusting the connectors and connecting pipes, the locking pin needs to be pressed until it is fully embedded in the bushing. The bushing provides guidance for the extension and retraction of the locking pin, preventing misalignment between the end of the locking pin and the through hole. The limiting rod and the limiting hole serve the same function; the limiting rod also fixes the spring, preventing misalignment.

[0030] Locking pin 4 and ring 5 are installed as a whole on the port side of the connector and fixed by welding. A limiting ring 32 is sleeved and fixed on the port side of connector 3. The ring is used to limit the installation of the connecting ring; the outer wall of the ring and the inner wall of the connector have a clearance fit. After the ring is installed, the contact portion between the edge of the ring and the connector is welded and fixed.

[0031] like Figure 2 As shown: A hexagonal prism-shaped rotating part 33 is provided at the connection position between the connector 3 and the stud 31. This allows for manual or wrench-assisted rotation of the connector.

[0032] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
