[0002] Galvanized steel pipes are widely used in building, municipal engineering, and industrial piping systems due to their excellent corrosion resistance and mechanical properties. Traditional connection methods for galvanized steel pipes mainly include threaded connections, welding, or clamp connections. However, these methods have significant drawbacks: threaded connections require on-site thread machining, resulting in low installation efficiency and potential damage to the galvanized layer, leading to corrosion; welding requires specialized equipment and technology, has a long construction period, and is inconvenient to disassemble; while clamp connections allow for quick installation, their sealing relies on the compression deformation of the rubber sealing ring, making them prone to failure under high pressure or vibration environments, and they lack reliable anti-loosening structures, posing a risk of loosening. Furthermore, existing connection components lack sufficient guidance, leading to deviations during assembly, affecting installation accuracy and efficiency, and the structural strength and surface anti-corrosion treatment of the connection points are insufficient to meet the demands of long-term use in harsh environments. Utility Model Content

[0003] To overcome the shortcomings of existing technical solutions, this utility model provides a magnetic quick-connect galvanized steel pipe assembly, which can effectively solve the problems mentioned in the background technology.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

The first galvanized steel pipe has a protruding magnetic connector at its connecting end, and the second galvanized steel pipe has a magnetic groove at its connecting end that mates with the magnetic connector.

[0006] An annular sealing ring is provided between the contact surfaces of the magnetic connector and the magnetic groove.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a magnetic quick-connect galvanized steel pipe assembly, including a first galvanized steel pipe 1 and a second galvanized steel pipe 2. The first galvanized steel pipe 1 is provided with a protruding magnetic connector 301 at its connecting end, and the second galvanized steel pipe 2 is provided with a magnetic groove 302 that cooperates with the magnetic connector 301 at its connecting end.

[0025] In this embodiment, during the docking process, the magnetic connector 301 at the docking end of the first galvanized steel pipe 1 and the magnetic groove 302 at the docking end of the second galvanized steel pipe 2 play a crucial role. The magnetic connector 301 is made of neodymium iron boron magnets and has strong magnetism, while the inner wall of the magnetic groove 302 is embedded with magnetic blocks 202 of opposite polarity. When the two come close, due to the attraction between opposite magnetic poles, the magnetic connector 301 is attracted into the magnetic groove 302, achieving initial rapid docking. During this process, the adsorption surface of the magnetic block 202 and the adsorption surface of the magnetic connector 301 are completely in contact, ensuring the maximum magnetic force application area and a tight connection between the two.

[0026] Meanwhile, the guide bevel (inclination angle of 45°-60°) at the end of the magnetic connector 301 cooperates with the guide chamfer at the opening of the magnetic groove 302 to guide the magnetic connector 301 to be smoothly inserted into the magnetic groove 302, reducing resistance and deviation during docking and improving the convenience and accuracy of docking.

[0027] When the magnetic connector 301 is inserted into the magnetic groove 302, the limiting protrusions 103 (multiple protrusions evenly distributed along the circumference) on the outer periphery of the magnetic connector 301 engage with the limiting grooves 201 (multiple grooves corresponding to the protrusions) on the inner wall of the magnetic groove 302. The engagement angle between the protrusions and the grooves is 30°-60°. This design ensures that after docking, the two form an anti-detachment engagement structure. When the steel pipe assembly is subjected to axial tension or other external forces, the engagement of the limiting protrusions 103 and the limiting grooves 201 effectively prevents the magnetic connector 301 from detaching from the magnetic groove 302, enhancing the stability and reliability of the connection.

[0028] In terms of sealing, the annular groove 104 of the magnetic connector 301 is fitted with an annular sealing ring 105, and the bottom of the magnetic groove 302 is provided with a sealing step that cooperates with the sealing ring 105. When the magnetic connector 301 is fully inserted into the magnetic groove 302, the sealing ring 105 will come into close contact with the sealing step, forming an annular sealing structure, thereby preventing fluid or gas from leaking from the joint and ensuring the sealing performance of the pipeline system.

[0029] In addition, the reinforcing ribs 102 (multiple triangular ribs evenly distributed along the circumference of the first galvanized steel pipe 1) provided between the magnetic connector 301 and the first galvanized steel pipe 1 can enhance the connection strength between the magnetic connector 301 and the first galvanized steel pipe 1 and reduce deformation or damage caused by force during use.

[0030] An annular sealing ring 105 is provided between the contact surfaces of the magnetic connector 301 and the magnetic groove 302. A limiting protrusion 103 is also provided on the outer periphery of the magnetic connector 301. A limiting groove 201 is correspondingly provided on the inner wall of the magnetic groove 302. The limiting protrusion 103 and the limiting groove 201 form an anti-detachment and locking structure.

[0031] When the first steel pipe (with magnetic connector 301) approaches the second steel pipe (with magnetic groove 302), the neodymium iron boron magnet (N35-N52 grade, high magnetic energy product) generates a strong attraction with the magnetic block 202 with opposite polarity in the groove (magnetic induction intensity can reach 0.4-0.6T). The symmetrical distribution of the opposite magnetic field causes the connector to automatically slide into the center of the magnetic groove 302, achieving sub-millimeter precision alignment (error <0.5mm), without the need for manual fine adjustment.

[0032] Furthermore, the magnetic connector 301 is made of neodymium iron boron magnet, and the inner wall of the magnetic groove 302 is inlaid with a magnetic block 202 with the opposite polarity to the magnetic connector 301. The adsorption surface of the magnetic block 202 is completely in contact with the adsorption surface of the magnetic connector 301.

[0033] The magnetic drive connector is fully embedded in the magnetic groove 302 (depth adaptation tolerance ±0.1mm), compressing the annular sealing ring 105 (EPDM or fluororubber material). The sealing ring 105 is subjected to axial compression deformation (compression rate 15%-20%), filling the micro-gaps on the contact surface to form an IP68-level seal (pressure resistance ≥1.6MPa), effectively blocking water vapor and corrosive media.

[0034] Furthermore, the sealing ring 105 is embedded in the annular groove 104 of the magnetic connector 301, and the bottom of the magnetic groove 302 is provided with a sealing step that cooperates with the sealing ring 105.

[0035] Furthermore, the limiting protrusion 103 is a plurality of protrusions evenly distributed along the circumference of the magnetic connector 301, and the limiting groove 201 is a plurality of grooves corresponding to the protrusions, with the mating angle between the protrusions and the grooves being 30°-60°.

[0036] Furthermore, the thickness of the magnetic connector 301 is 1.5-2 times the wall thickness of the first galvanized steel pipe 1, and the depth of the magnetic groove 302 is adapted to the thickness of the magnetic connector 301.

[0037] Furthermore, the outer surfaces of the first galvanized steel pipe 1 and the second galvanized steel pipe 2 are both provided with a galvanized layer 3, and the surfaces of the magnetic connector 301 and the magnetic groove 302 are both coated with a nickel-phosphorus alloy layer 101.

[0038] Furthermore, the end of the magnetic connector 301 is also provided with a guide slope, the inclination angle of which is 45°-60°, and the opening of the magnetic groove 302 is provided with a guide chamfer that cooperates with the guide slope.

[0039] Magnetic attraction and guide bevel (45°-60°) reduce the time for a single connection to less than 3 seconds, which is a significant improvement in efficiency compared to traditional threaded connections (≥30 seconds / connection).

[0040] Furthermore, a reinforcing rib 102 is provided between the magnetic connector 301 and the mating end of the first galvanized steel pipe 1. The reinforcing rib 102 consists of multiple triangular ribs evenly distributed along the circumference of the first galvanized steel pipe 1.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
