Example

[0012] In the following, an embodiment of the present invention is explained in more detail with reference to the drawings.

[0013] As in the Fig.1 to 7, the present utility model provides a magnetic universal safety buckle comprising a magnet, a protective cap 1, a buckle body 2, a first snap buckle 3, a second snap buckle 4, a fastening element 5, and a fastening base 6, wherein a tab 50 is integrally formed in the fastening element 5; wherein a second magnet 200 is provided in the inner cavity of the tab 50, and wherein the position of the second magnet 200 is embedded in the inner cavity of the tab 50 by means of a fastening base 6 for fastening; wherein the first snap buckle 3 and the second snap buckle 4 are symmetrically mounted in the inner cavity of the buckle body 2, their mounting positions being limited by the assembly of the buckle body 2 with the protective cap 1;wherein a center hole 20 is formed in the bottom of the buckle body 2, wherein the fastening element 5 passes through the center hole 20 via the tab 50 and fits with an elastic arm 300 of the first snap buckle 3 and the second snap buckle 4, and is then movably connected to the buckle body 2; wherein a first magnet 100 is embedded in the fastening ring 23 in the inner cavity of the buckle body 2, wherein the fastening element 5 and the buckle body 2 are formed with lacing grooves;

[0014] The connection and fastening of the protective cap 1 and the buckle body 2 is carried out by screws, namely screws through the screw holes 22 of the buckle body 2, which are then screwed into the inner threaded connecting pins 10 on the underside of the protective cap 1, whereby the two are connected and fastened together.

[0015] The first magnet 100 and the second magnet 200 are adsorbed to each other in the same axial direction during and after assembly. Such a design not only allows the user to buckle the strap precisely and comfortably during one-handed or blind assembly, but also serves as additional reinforcement in addition to the snap closure to prevent loosening.

[0016] As for the use of the utility model, the present utility model is formed with three lacing grooves, namely the first lacing groove 21 on the buckle body of the buckle and the left lacing groove 51 and the right lacing groove 52 on the fastening element 5, so that the user can perform three-point or two-point lacing according to the actual usage situation.

[0017] When combining the buckle body 2 and the fastening element 5 of the present utility model, the user can use the buckle body 2 and the fastening element 5 in combination thanks to the cooperation of the tab 50 and the center hole 20, as well as the adsorption guide between the magnets. The user can assemble the fastening element 5 and the buckle body 2 with one hand or blindly, and the assembled buckle body 2 can be adjusted within a 360° angular range based on the fastening element 5, so that the first lacing groove 21 can be adjusted with the shoulder strap according to the actual fastening needs.

[0018] When the buckle is to be disassembled, it is sufficient to press the first snap buckle 3 and the second snap buckle 4 simultaneously with one hand, and the two buckles are deformed by the pressure, so that the clamping jaw 400 is released from the annular recess 500 of the tab 50 and then exerts a slight force outward, and then the buckle body 2 is released by the magnetic force on the fastening element 5 and disassembled downwards.

[0019] Regarding the first snap buckle 3 and the second snap buckle 4, it can be further stated that the first snap buckle 3 and the second snap buckle 4 are each provided with a limiting member 600, which ensures the stability of the first snap buckle 3 and the second snap buckle 4 in the cavity formed by the buckle body 2 and the fastening member 5 and ensures that they can be movably operated without any displacement or shifting that could impair the pressing and releasing of the buckle; similarly, the snap partition plate 24 in the inner cavity of the buckle body 2, both of which serve to improve the working efficiency and safety of the present utility model.

[0020] The jaws 400 of the elastic arm 300 are formed in a circular arc shape, which not only better fits into the annular recess 500 of the cylindrical shape of the tab 50, but also allows the jaws 400 to enter the annular recess 500 more smoothly when the present utility model is buckled; Because the outer surface of the jaw 400 also has a chamfered shape, compared with the straight vertical surface of the snap fastener, a chamfered shape of the contact surface undoubtedly has a better transition effect and better performance to avoid the occurrence of the problem of difficult buckling of the upper buckle.

[0021] The present utility model provides a simple assembly but reasonable structure of the safety buckle through the tab 50, the snap buckle and the magnet, and in order to ensure its strength, a one-piece molding process and the design of the reinforcing bar were also adopted to ensure the longevity of its use.

[0022] The above detailed description refers to a feasible embodiment of the present invention, but the embodiment should not limit the scope of the present invention. All equivalent embodiments or modifications that do not deviate from the spirit of the present invention should be included within the scope of the present invention.
