Description

Technical Field

[0001] This utility model belongs to the field of safety fastener technology, and in particular relates to a magnetic universal safety fastener. Background Technology

[0002] Buckles are widely used in various everyday items (such as backpacks, strollers, etc.) as the main control device for fastening or unfastening straps. Traditional buckles generally consist of opposing male and female fasteners, which are connected to opposite ends of the strap. The engagement or disengagement of the entire strap can be controlled by the interlocking of the male and female fasteners or by the pressing and releasing of a preset lever control.

[0003] However, the buckles currently on the market are bulky in design and not very convenient to use. Utility Model Content

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A magnetic universal safety buckle includes a magnet, a cover, a buckle body, a first buckle, a second buckle, a fixing member, and a fixing base. The fixing member has an integrally formed boss; a second magnet is disposed within the inner cavity of the boss, and the position of the second magnet is fixed by the fixing base being embedded in the inner cavity of the boss; the first and second buckles are symmetrically placed within the inner cavity of the buckle body, and their installation positions are restricted by the assembly of the buckle body and the cover; a central hole is formed at the bottom of the buckle body, and the fixing member, through its boss passing through the central hole, engages with the elastic arms of the first and second buckles to movably connect with the buckle body; a first magnet is embedded in the fixing ring within the inner cavity of the buckle body; and both the fixing member and the buckle body have strap grooves formed on them.

[0006] Preferably, the first magnet and the second magnet are attracted to each other in the same axial direction when the fastener body is assembled with the fixing member and after assembly.

[0007] Preferably, the inner cavity of the buckle body is symmetrically formed with reinforcing ribs, screw holes, fixing rings and buckle partitions, and a first strap groove is integrally formed on one outer edge.

[0008] Preferably, the inner wall of the bottom of the cover is also symmetrically formed with reinforcing ribs and internal threaded connecting posts corresponding to the inner cavity structure of the fastener body.

[0009] Preferably, the protrusion is designed with an annular groove to be movably connected with the elastic arms of the first and second buckles.

[0010] Preferably, the claws of the elastic arms on the first and second buckles are both designed in an arc shape.

[0011] Preferably, the buckle body can be rotated to adjust the angle after being assembled with the fixing member.

[0012] Preferably, both the first and second buckles are formed with limiting components.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] 1. This utility model is a magnetic safety buckle with a simple and reasonable structure, stable and convenient use, and adjustable angle. The buckle body has one strap groove, while the fixing part has two strap grooves. The two are connected to each other by the cooperation of the boss and the buckle. The boss and the inner cavity of the buckle body are also embedded with magnets to guide the assembly. When the two are assembled, they can play a role in positioning by magnetic attraction. This design can help users to fasten accurately and conveniently even if they operate with one hand or blindly fasten.

[0015] 2. This utility model can be used for three-point or two-point strapping according to actual conditions, which can meet various usage needs in more occasions. It is worth mentioning that after the fixing part is fixed to the buckle body, it can be rotated independently to adjust the angle. The adjustable angle is 360°. This function greatly improves the practicality of this utility model in the case of three-point strapping. Attached Figure Description

[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. 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.

[0022] like Figures 1 to 7 As shown, this utility model is a magnetic universal safety buckle, including a cover 1, a buckle body 2, a first buckle 3, a second buckle 4, a fixing member 5, and a fixing base 6. The fixing member 5 has an integrally formed boss 50; a second magnet 200 is disposed in the inner cavity of the boss 50, and the position of the second magnet 200 is fixed by the fixing base 6 embedded in the inner cavity of the boss 50; the first buckle 3 and the second buckle 4 are symmetrically placed in the inner cavity of the buckle body 2, and their installation positions are restricted by the assembly of the buckle body 2 and the cover 1; a central hole 20 is opened at the bottom of the buckle body 2, and the fixing member 5, through its boss 50 passing through the central hole 20, cooperates with the elastic arms 300 of the first buckle 3 and the second buckle 4 to movably connect with the buckle body 2; a first magnet 100 is embedded in the fixing ring 23 in the inner cavity of the buckle body 2; and both the fixing member 5 and the buckle body 2 have strap grooves formed on them.

[0023] The connection and fixation between the cover 1 and the buckle body 2 are achieved by screws. Specifically, the screws pass through the screw hole 22 of the buckle body 2 and are screwed into the internal threaded connecting post 10 at the bottom of the cover 1, thereby connecting and fixing the two together.

[0024] In this invention, the first magnet 100 and the second magnet 200 are attracted to each other in the same axis during and after assembly. This design not only allows users to accurately and conveniently fasten the magnets with one hand or blindly, but also provides auxiliary reinforcement in addition to snap fastening, preventing loosening.

[0025] Regarding the use of this utility model, there are three strap grooves formed by this utility model, namely the first strap groove 21 on the buckle body and the left strap groove 51 and right strap groove 52 on the fixing member 5. Users can perform three-point strapping or two-point strapping according to the actual use situation.

[0026] When the buckle body 2 and the fixing member 5 of this utility model are used together, thanks to the cooperation between the boss 50 and the center hole 20, as well as the attraction guidance between the magnets, the user can assemble the fixing member 5 and the buckle body 2 with one hand or blindly. The assembled buckle body 2 can be adjusted 360° based on the fixing member 5, so that the first strap groove 21 with the shoulder strap can be adjusted according to the actual fixing needs. When it is necessary to disassemble and untie, simply press the first buckle 3 and the second buckle 4 with one hand at the same time. The two buckles will be deformed by pressure, so that the claw 700 will disengage from the annular groove 500 of the boss 50. With a little outward force, the buckle body 2 can be disengaged from the magnet and removed from the fixing member 5.

[0027] Regarding the first buckle 3 and the second buckle 4, it can be further explained that each of the first buckle 3 and the second buckle 4 is formed with a limiting member 600, which can ensure the working stability of the first buckle 3 and the second buckle 4 in the enclosed cavity formed by the buckle body 2 and the fixing member 5. This ensures that they can move and work while preventing them from coming off or shifting, which would affect the pressing and unhooking. Similarly, there is a buckle partition plate 24 in the inner cavity of the buckle body 2. Both of these designs can improve the working effect and safety of this utility model.

[0028] Regarding the claws 400 of the elastic arm 300, all claws 400 are designed with an arc shape. This design not only allows them to fit more closely to the annular groove 500 of the cylindrical boss 50, but also increases the smoothness of the claws 400 entering the annular groove 500 when the device is fastened. Since the outer surface of the claws 400 is also designed with a slope, compared with the straight-in and straight-out vertical surface fastening, the sloped contact surface undoubtedly has a better transition effect and working performance, avoiding the problem of difficulty in fastening when fastening.

[0029] This utility model provides a safety buckle that is simple to assemble but has a reasonable structure through the protrusion 50, the buckle and the magnet. In order to ensure its strength, it also uses a one-piece molding process and has reinforcing ribs, thereby ensuring its durability.
