[0030] To solve the technical problems in the background art, as shown in Figures 1-7 The present application provides a technical solution: a high-strength multi-angle plastic pipe joint, characterized by:

[0031] The joint body 1 is a cylindrical cavity structure, and a plurality of through holes 2 are uniformly distributed on the side wall of the joint body 1, which are used to install the connecting pipes 4. The joint body 1 is provided with a conical table 3 on each bottom surface, and the conical table 3 is coincident with the bottom surface of the joint body 1 and is integrally formed, thereby enhancing the stability of the joint body 1. The connecting pipe 4 is arranged at the through hole 2 of the joint body 1, and the connecting end 5 of the connecting pipe 4 is in communication with the internal cavity of the joint body 1. The outer wall of the connecting pipe 4 is provided with a reinforcing sheet 6 to enhance the strength of the connecting pipe 4. The outer wall of the insertion end 7 of the connecting pipe 4 is provided with a tapered tooth 8, which gradually tapers from the connecting end 5 to the insertion end 7, so as to ensure the firmness of the connection with other pipelines. The tapered tooth 8 can tightly engage the inner wall of the target pipeline, providing strong friction and gripping force, ensuring the stability of the connection and preventing loosening under pressure changes or vibration environment. The design of the tapered tooth 8 makes the connecting pipe 4 more smooth when inserted into the pipeline, reducing the resistance in the installation process. The tight engagement of the tapered tooth 8 helps to improve the sealing of the pipeline connection, reducing the risk of fluid leakage, especially in high-pressure or corrosive environments. The plug 9 is arranged in the connecting pipe 4 to seal the connecting pipe 4 and prevent fluid leakage. The center column 10 is arranged in the connecting pipe 4 coaxially with the connecting pipe 4. One end of the center column 10 is connected to the plug 9, and the other end is connected to the lug 11. This design makes the plug 9, the center column 10 and the lug 11 an integral whole. When the connecting pipe 4 at this position needs to be connected to the pipeline for use, the plug 9 can be removed from the connecting pipe 4 by pulling the lug 11.

[0032] In use, the through holes 2 are uniformly arranged along the side wall of the joint body 1, so that the connecting pipes 4 can uniformly distribute the force on the joint body 1 when inserted, reducing local stress concentration and thereby improving the durability and reliability of the joint. The uniformly distributed through holes 2 provide multiple connection points. The plurality of uniformly distributed through holes 2 enable the joint body 1 to support multi-angle pipeline connections, meet the needs of pipeline layout in different directions, and enhance the applicability of the joint.

[0033] It should be noted that the axis of the connecting pipe 4 intersects the central axis of the joint body 1, so that the connecting pipe 4 can form a fixed angle with the joint body 1, thereby achieving uniform distribution of multiple connecting pipes 4 around the joint body 1. Since the axis of the connecting pipe 4 intersects the central axis of the joint body 1, this structure can provide better torsional and tensile strength, thereby enhancing the overall connection strength of the joint.

[0034] Further, the cross-sectional area of the reinforcement plate 6 is larger than that of the connecting pipe 4, and the larger cross-sectional area of the reinforcement plate 6 provides more material to bear the load, thereby enhancing the load-bearing capacity and anti-deformation capacity of the connecting pipe 4. The larger cross-sectional area means that the contact area between the reinforcement plate 6 and the connecting pipe 4 is larger, which helps to improve the stability of the connection and reduce loosening or rotation caused by external forces. When subjected to external forces, the larger cross-sectional area can help to disperse stress and reduce local stress concentration, thereby reducing the risk of fracture or damage to the connecting pipe 4. The presence of the reinforcement plate 6 itself is to enhance the strength of the connecting pipe 4, and the larger cross-sectional area means that more material is involved in bearing, thereby improving the overall strength of the connection.

[0035] It should be noted that the reinforcement plate 6 is coaxially arranged with the connecting pipe 4, maintaining the symmetry of the structure, which helps to evenly distribute the load and reduce structural deformation or damage caused by asymmetric forces. The coaxially arranged reinforcement plate 6 can directly enhance the strength of the connecting pipe 4, especially when subjected to axial forces or torque, this configuration can provide better support and anti-deformation capacity.

[0036] Further, the plug 9, the center column 10 and the protrusion 11 are integrally formed, making the entire structure more compact, and the integrally formed design enhances the connection strength between the components, improves the stability and reliability of the overall structure, and facilitates the insertion and removal of the plug 9. When the plug 9 is inserted into the connecting pipe 4, the connecting pipe 4 is in a sealed state, i.e. in an inactive state; when the plug 9 is removed by the protrusion 11, the connecting pipe 4 is in an active state, at which time the pipe can be inserted into the connecting pipe 4 for connection.

[0037] It should be noted that the continuous teeth 8 provide multiple contact points, increasing the friction between the connecting pipe 4 and the target pipe, thereby improving the engagement strength and stability of the connection. The stepped structure formed by the continuous teeth 8 helps to prevent the connecting pipe 4 from rotating or loosening in the pipe system, especially when subjected to vibration or pressure changes. The teeth 8 of the stepped structure help to form a tighter seal, reducing the risk of fluid leakage, especially in high-pressure or corrosive environments.

[0038] It should be noted that the outer periphery of the reinforcement plate 6 is designed as a hexagon, which is particularly convenient for using a wrench to operate, so that the user can easily grasp and rotate the reinforcement plate 6, facilitating the installation and removal of the pipe on the connecting pipe 4.

[0039] Although embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
