Description

Technical Field

[0001] The utility model relates to a safety buckle for locking a safety belt, in particular to a five-point magnetic reverse-thrust safety buckle. Background Art

[0002] For safety reasons, cars, strollers, and those working at heights are often equipped with safety belts to ensure personal safety. However, conventional safety buckles are designed with only one buckle, meaning that only one can be opened at a time. If a person needs to wear two or more safety belts simultaneously, the process of unfastening the buckles requires pressing a corresponding number of buckles, which is very cumbersome. For example, in a stroller, to prevent a baby from falling out of a single safety belt, multiple safety belts are often required to secure the baby's crotch, waist, or shoulders. When a baby tires in the stroller and urgently needs to be held, or when someone is rushing to help with the baby's bowel movement, it often takes a long time to unfasten each safety buckle, preventing the baby from receiving timely and effective care. Therefore, it is necessary to invent a new safety buckle that can be easily and quickly unfastened. Utility Model Content

[0003] In order to solve the above problems, the present invention adopts the following technical solutions:

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1 to 9 As shown, the present invention is a five-point magnetic reverse push safety buckle, which is mainly composed of two parts, namely a male buckle part 1 and a female buckle part 2. The male buckle part 1 and the female buckle part 2 are assembled together by the movable cooperation between the latch 201 and the fixed guide column 100 and the magnetic cooperation between the magnets. It should be noted that two magnets with opposite magnetic poles are arranged in the female buckle part 2, namely the second magnet 220 and the fifth magnet 221. The second magnet 220 and the fifth magnet 221 are respectively embedded in the positive hole 222 and the reverse hole 223 opened in the pressing member 22. The second magnet 220 is arranged at the positive hole position 222 to cooperate with the first magnet 101 in the fixed guide column 100 directly below it based on the principle of opposite poles attracting each other during the locking action or after the buckling is completed. The fifth magnet 221 is arranged at the reverse hole position 223. When the pressing member 22 is pressed and moved, it will be driven to the top of the fixed guide column 100, so that it can cooperate with the first magnet 101 based on the principle of like poles repelling each other, thereby allowing the male buckle part 1 and the female buckle part 2 to obtain a repulsive force instead of the previous magnetic confrontation, achieving easier and faster unlocking and unfastening.

[0026] The male buckle part 1 includes a male buckle seat 10, a male buckle 11, a first connecting fastener 12 and a second connecting fastener 13. The male buckle seat 10 is integrally formed with a fixed guide column 100 with a clamping ring groove 103. The clamping ring groove 103 cooperates with the clamping tongue 201 to achieve reinforced locking after buckling; the male buckle seat 10 and the male buckle 11 are both formed with a clamping groove 106 to clamp the first connecting fastener 12 and the second connecting fastener 13 respectively. This design is convenient and efficient for production assembly and future separate replacement and disassembly, and its cross section is a "T"-shaped or "I"-shaped structure, which can also ensure strength and stability during use and ensure the safety of users; the male buckle seat 10 and the male buckle 11 are The two parts have a split structure, and each part is provided with a magnet to assist the blind buckle during assembly. Specifically, a third magnet fixing hole 104 is formed on the male buckle seat 10 to install the third magnet 105, and the male buckle 11 is provided with a fourth magnet fixing hole 111 to install the fourth magnet 113. The two parts are perpendicular to each other in their positions after assembly, so as to cooperate with each other to the greatest extent based on the principle of attraction between opposite poles. To ensure stability and strength, the male buckle seat 10 is also integrally formed with a positioning cavity 102 for the positioning protrusion 110 on the male buckle 11 to be embedded in it to assist in positioning, clamping and reinforcement. Therefore, the male buckle seat 10 and the male buckle 11 have magnets and concave and convex parts to assist in positioning assembly and reinforce assembly strength.

[0027] In order to prevent the male buckle part 1 with a hole at the bottom for assembling the magnet from falling off easily, the male buckle part 1 is provided with a joint cover 107 to provide a joint cover 107 for the fixed guide column 100 on which the first magnet 101 is installed and the fixing hole 104 on which the third magnet 105 is installed. The said joint cover 107 can cover two holes. Since the fixed guide column 100 is a hollow design, a hole is formed at its bottom, and the hole is in the same plane as the fixing hole 104, so the joint cover 107 can be designed based on a reasonable and simple structure. The fourth magnet fixing hole 111 also plays the same role and is provided with a cover 112 to prevent the fourth magnet 113 from falling out of the fourth magnet fixing hole 111 during opening and closing and shaking in daily use.

[0028] The female buckle portion 2 includes a base 20, an upper cover 21 and a pressing member 22. A pair of tongues 201 equipped with a return spring 200 and a pressing member 22 with a return spring 200 are provided in the base 20. The inner cavity of the base 20 is symmetrically designed with a fixing groove 202 to install the tongue 201 equipped with the return spring 200. It is also formed with a guide groove 203 and a limit baffle 204 to assist the pressing member 22 in directional installation and movement limitation. The tongue 201 has a countersunk hole for the return spring 200. The positioning spring 200 is assembled to assist in positioning, and the pressing piece 22 is also integrally formed with a spring guide column 224 for the reset spring 200 to be positioned. The function of each reset spring 200 is to reset the pressing piece 22 or the tongue 201 after the pressing piece 22 is compressed. Such a design can complement each other and significantly improve the stability and safety of the utility model, ensuring that the tongue 201 can enter the fixing ring groove 103 and stabilize its position when locking the buckle, avoiding the situation where the safety buckle cannot be effectively fixed. What needs to be noted in this part is that the bottom of the pressing member 22 is designed with an inclined push surface 225 that cooperates with the tongue 201. When the pressing member 22 is gradually pressed forward, it can smoothly and gradually compress the tongue 201, so that the unlocking and buckling action is smooth, and it can also allow the fifth magnet 221 to move to the top of the first magnet 101 with a distance transition, avoiding accidental touch due to the wide opening and closing structural design, which may cause accidental release too quickly. Since accidental touch will occur more often in baby fixation, the gradual slope can bring better use effect, which is different from the other one-button release effects that are only fast but not stable.

[0029] It can be further explained that both the base 20 and the upper cover 21 are provided with screw holes for connecting and fixing them to each other by screws.

[0030] The present invention is a five-point magnetic reverse push safety buckle, so the male buckle seat 10, male buckle 11, first connecting fastener 12, second connecting fastener 13 and base 20 are all integrally formed with a lace groove 3, but it can be seen that the technical principle and structure of the present invention are not limited to the five-point structure.

[0031] The utility model has a simple and reasonable structure and high safety. Compared with the traditional method of working with two magnets as a group, the utility model innovatively uses three magnets as a working group to realize the attraction and repulsion buckle design, which can greatly improve the operation of blind buckle and release, and is suitable for use in most occasions, achieving the research and development purpose of being able to unlock the fastener conveniently and quickly.
