Description

Technical Field

[0001] This utility model relates to the field of structural connectors, and in particular to a structural connector. Background Technology

[0002] As a key component in spatial structural connections, the tee joint's three-dimensional orthogonal interface design (typically including one main pipe interface and two branch pipe interfaces, or three symmetrically distributed interfaces of the same diameter) enables rigid connections of supporting components in the X / Y / Z axis directions. Through precise angular positioning, a stable geometric support system is constructed in the spatial coordinate system, allowing multi-dimensional loads (axial tension / compression, lateral shear force, torque) to be effectively transmitted and evenly distributed through the joint body.

[0003] Traditional tee connectors, due to their dual-channel structure with the main interface and branch pipes perpendicular to each other, require a step-by-step demolding process: first, the branch pipe core is pulled out using a lateral core-pulling mechanism to avoid interference with the main pipe core, and then the main pipe core is pulled out axially. If a one-piece core is used, its "L-shaped" undercut can cause tearing of the inner wall of the plastic part. For curved inner wall bends, traditional linear core-pulling mechanisms are unsuitable; a hydraulically driven arc-shaped slider must move along the curvature of the bend to pull the core in segments. After the core is detached, an ejector system pushes the product out to prevent friction between the core and the inner wall. When the same nominal outer diameter matches different inner diameters, an adjustable core with a radial adjustment mechanism is required. During demolding, the core must first be radially contracted before axially pulling it out, increasing the demolding process. Therefore, a structural connector needs to be designed.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] This utility model provides a structural connector to solve the problems of traditional tee connectors requiring step-by-step demolding due to their orthogonal dual-channel structure, the need for hydraulic segmented core pulling for curved bends, and the increased demolding process caused by adjustable cores during diameter changes.

[0006] The present invention adopts the following technical solution: a structural connector, mainly including a connecting pipe, wherein each of the three sets of connecting ends of the connecting pipe extends outward with two sets of symmetrically distributed bosses, and a positioning gap is formed between the two sets of bosses. The three sets of connecting ends of the connecting pipe are respectively connected to a supporting member. The end of the supporting member is provided with a mating groove that is completely adapted to the shape and size of the bosses. The end of the supporting member is provided with a pin block adapted to the supporting member.

[0007] Furthermore, the three sets of connecting ends of the connecting pipe fitting are provided with a reinforcing component. The reinforcing component includes a fixing ring sleeve one that is fixedly sleeved at the three sets of connecting ends of the connecting pipe fitting, and a fixing ring sleeve two installed at the end of the supporting member. At least four sets of spring fasteners are distributed equidistantly along the circumference of the fixing ring sleeve one, and a fastening block matching the spring fastener is provided on the fixing ring sleeve two.

[0008] Furthermore, the spring-loaded fastener is made of highly elastic plastic material.

[0009] Furthermore, the spring-loaded fastener is L-shaped.

[0010] Furthermore, an anti-slip pad is provided at the contact position between the docking groove and the boss, and the anti-slip pad is made of silicone.

[0011] Furthermore, a sealing ring is embedded in the partial contact area between the first fixing ring and the second fixing ring.

[0012] Furthermore, the connecting pipe has a T-shaped structure.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0014] A structural connector allows for modular connection by using a boss and positioning gap at the connecting end of a connecting pipe to mate with a groove and pin at the end of a supporting component. This eliminates the need for complex demolding mechanisms such as traditional step-by-step core pulling or arc-shaped core pulling, simplifying mold design and avoiding tearing issues caused by L-shaped undercuts. When adapting to curved pipes, it allows for segmented demolding along the axis. It is compatible with supporting components of different inner diameters, eliminating the need for radial adjustment cores and reducing demolding steps. Furthermore, the dual positioning of the tenon and pin enhances the connection's torsional and tensile strength, improving structural stability and reliability, and optimizing production efficiency and performance.

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1-3 As shown, this embodiment of the utility model provides a structural connector, including a connecting component 1. The connecting component 1 includes a connecting pipe 11, which is a T-shaped structure used to achieve a stable spatial connection of at least three supporting members 14. Its T-shaped design includes three connecting ends that are perpendicular to each other or distributed at a specific angle, which can be rigidly connected to horizontal, vertical, or oblique supporting pipes (such as metal pipes, composite profiles, etc.).

[0026] Furthermore, each of the three sets of connecting ends of the connecting pipe fitting 11 has two sets of symmetrically distributed bosses 12 extending outwards, and a positioning gap 13 is formed between the two sets of bosses 12. At the same time, support members 14 are connected to the three sets of connecting ends of the connecting pipe fitting 11. The end of the support member 14 is provided with a mating groove 16 that is completely adapted to the shape and size of the bosses 12. A pin block 15 adapted to the support member 14 is integrally provided at the end of the support member 14. At the same time, a threaded hole 151 is provided on the pin block 15 for subsequent bolt fastening.

[0027] The initial positioning is achieved through the tenon and mortise fit between the boss 12 and the mating groove 16; the positioning gap 13 and the pin 15 fit each other to form a secondary directional lock; when the pin 15 is inserted into the positioning gap 13, its side fits tightly against the inner wall of the boss 12, forming a circumferential anti-rotation limit, avoiding structural instability caused by misalignment of the support member 14; the guiding function of the pin 15 and the positioning gap 13 makes it possible to insert the support member 14 without additional positioning tools, and to directly fasten it by passing the bolt through the positioning gap 13 and screwing it into the threaded hole 151 of the pin 15, thereby improving the connection stability;

[0028] In this application, an anti-slip pad 17 can be provided at the contact position between the mating groove 16 and the boss 12. The anti-slip pad 17 is made of silicone. With its high elasticity and strong adhesion, the silicone anti-slip pad 17 tightly fills the tiny gap between the boss 12 and the mating groove 16, eliminating the risk of relative sliding between the contact surfaces. The anti-slip pad 17 adopts an embedded structure design, which can seamlessly fit with the inner wall of the mating groove 16 or the surface of the boss 12, so as to achieve convenient installation and disassembly without changing the original tenon and mortise structure.

[0029] like Figures 3-4 As shown, a reinforcing component 2 is provided at the three sets of connection ends of the connecting pipe fitting 11. The reinforcing component 2 is used to increase the connection between the connecting pipe fitting 11 and the supporting member 14. The reinforcing component 2 includes a fixing ring sleeve 1 21 fixedly sleeved at the three sets of connection ends of the connecting pipe fitting 11, a fixing ring sleeve 23 fixedly installed at the end of the supporting member 14, and at least four sets of spring fasteners 22 are distributed at equal intervals along the circumference of the fixing ring sleeve 1 21. The spring fasteners 22 are L-shaped and made of highly elastic plastic material, which has both flexibility and deformation resistance, and can quickly reset after being subjected to force. Correspondingly, the fixing ring sleeve 23 is provided with a fastening block 24 that matches the spring fasteners 22.

[0030] When the support member 14 and the connecting pipe 11 are connected, the fastener 24 first contacts the spring fastener 22. As the insertion progresses, the spring fastener 22 is compressed and undergoes elastic deformation. When the fastener 24 passes the critical point of the spring fastener 22, the spring fastener 22 quickly rebounds and engages with the fastener 24, forming a mechanical lock. This process is synchronized with the tenon and mortise structure of the boss 12 embedded in the docking groove 16, achieving double locking. The spring fastener 22 and the fastener 24 provide axial anti-disengagement protection, while the structure of the boss 12 and the docking groove 16 ensures radial positioning and torsional strength, improving the overall reliability of the connection node. This design requires no tools and simplifies the installation process through a plug-and-play assembly mechanism, while effectively resisting the risk of loosening caused by external forces.

[0031] Furthermore, a sealing ring 25 is embedded in the contact area between the first fixing ring 21 and the second fixing ring 23. When the support member 14 and the connecting pipe 11 are connected, and the first fixing ring 21 and the second fixing ring 23 are in contact with each other, the sealing ring 25 is squeezed and filled in the gap between them. With its own elastic deformation, it enhances the sealing of the connection part, effectively preventing the intrusion of dust, water vapor and other substances, and improving the protective performance of the component in complex environments. Combined with the connection structure of the spring fastener 22 and the fastener block 24, and the boss 12 and the docking groove 16, the reliability and durability of the overall connection are further guaranteed from the sealing dimension.

[0032] In this application, the locking connection structure is applicable to multi-directional connectors such as tees, crosses, and fives. By applying this connection structure to multi-directional connectors such as tees and crosses, a stable and reliable spatial support can be constructed.

[0033] Working principle: During operation, the basic connection is first constructed using the connecting component 1: the connecting pipe 11 serves as the core T-shaped structure, and the bosses 12 at its three connecting ends form a tenon-and-mortise fit with the end grooves 16 of the support component 14 to achieve initial positioning; the positioning gap 13 engages with the pin block 15 to complete the secondary directional locking, and after the pin block 15 is embedded, it fits against the inner wall of the boss 12 to form a circumferential anti-rotation, allowing the support component 14 to be accurately and quickly inserted without additional tools. Subsequently, bolts can be used to strengthen the connection stability, and the silicone anti-slip pad 17 on the mating surface fills the tiny gaps to eliminate the risk of sliding, while also providing convenient assembly and disassembly characteristics;

[0034] Next, the reinforcing component 2 comes into play: when the support member 14 is connected, the buckle 24 on the second fixing ring 23 first touches the spring buckle 22 on the first fixing ring 21. As it is inserted and pushed forward, the spring buckle 22 is compressed and deformed. After the buckle 24 crosses the critical point, the spring buckle 22 springs back and locks in place, forming a double lock with the tenon and mortise structure, simplifying installation and preventing loosening. At the same time, the sealing ring 25 in the contact area between the first fixing ring 21 and the second fixing ring 23 is compressed and filled during the connection. The elastic deformation enhances the sealing performance, blocking dust and moisture, and from the sealing level, it helps to ensure the reliability and durability of the connection, achieving a spatially stable and well-protected connection for the support member 14.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
