Description

Technical Field

[0001] The utility model belongs to the technical field of safety buckles, and in particular relates to a rotatably adjustable three-point magnetic reverse-thrust safety buckle. Background Art

[0002] For safety reasons, cars, strollers, and those working at heights are often equipped with seat belts to ensure personal safety. There are many types of buckles that come with seat belts, one of which is a magnetic buckle that uses the principle of opposite magnets attracting each other to provide auxiliary fastening and reinforced connection. These buckles typically include a male buckle and a female buckle that work together, each with a magnet inside. When the male and female buckles are plugged together, the magnetic attraction guides them into position and allows them to quickly snap together. However, these plug-in magnetic buckles require the user to exert force or even use both hands to effectively unlock them. This is because the user must also resist the magnetic attraction and exert force to unlock the buckle, making it very inconvenient when holding a baby with one hand or in other emergency or special situations. Therefore, these plug-in magnetic buckles are relatively inconvenient to operate.

[0003] Furthermore, this type of plug-in magnetic fastener can only connect to the webbing at one end of the male and female buckles, which means that the male and female buckles can only be plugged in one direction and cannot be adjusted, making it inflexible and inconvenient to use. Therefore, it is necessary to provide a magnetic fastener with a simple structure, easy operation, and flexible use to solve the above problems in the prior art. Utility Model Content

[0004] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] Preferably, the fixed guide post is formed with an annular groove to cooperate with the latch.

[0007] Preferably, the magnet mounting holes are all provided with cover plugs.

[0008] Preferably, the first magnet mounting hole is a cavity for fixing the guide column, which is installed with a first magnet that cooperates with the third magnet and the fourth magnet, and the second magnet mounting hole is installed with a second magnet that cooperates with the fifth magnet.

[0009] Preferably, the auxiliary protrusion and the auxiliary countersunk hole are provided in relative positions so that the left buckle portion and the right buckle portion can be assembled and fixed in a concave-convex fit.

[0010] Preferably, the upper cover and the base are integrally formed with undercuts and buckles for interlocking assembly and fixation, and the upper cover is also formed with a guide rail to assist the directional movement of the latch.

[0011] Preferably, the latch tongue is provided with a countersunk hole for assembling the reset spring, and the pressing member is integrally formed with a positioning column for positioning and sleeve placement of the reset spring.

[0012] Preferably, the bottom of the pressing member is symmetrically formed with an inclined pushing surface that cooperates with the latch.

[0013] Preferably, the two magnet mounting holes on the pressing member are the third mounting hole and the fourth mounting hole respectively. The two magnet mounting holes are opened side by side, and the magnetic poles of the third magnet and the fourth magnet installed in these two magnet mounting holes are opposite to each other.

[0014] Preferably, the female buckle can be rotated 360° on the male buckle based on the engagement of its latching tongue with the annular groove of the male buckle.

[0015] Compared with the existing technology, the advantages of the present invention are: the present invention is an extension and development design of the safety buckle based on the magnetic buckle, so that when the buckle is locked, it can not only realize auxiliary blind buckle based on magnetic attraction, but also realize more convenient and quick unlocking based on the principle of like magnetic poles repelling each other, and through reasonable structural design, the female buckle can be rotated 360 degrees on the male buckle to make the present invention suitable for use in more situations and occasions. The principle of quick unlocking by like magnetic poles repelling each other is that when the lower pressing part is pressed to unlock, the fourth magnet inside it, which was originally attracted to the first magnet, will be pushed forward The latch is then released, and the third magnet that repels the first magnet is used instead. At the same time, the pressing member pushes the latch out of the annular groove, thereby realizing unlocking and unfastening. Compared with the previous magnetic safety buckle with two magnets in a group, this design can significantly reduce the suction force between the magnets when unlocking is required, and even act as a repulsive force, so that the user can separate the female buckle part from the male buckle part conveniently, quickly and labor-savingly, and effectively solve the magnetic confrontation generated when pressing to unlock with one hand. Combined with the 360° rotation adjustment, the utility model can be widely used in child safety seats, child push chairs, backpacks, luggage and other parts. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] 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.

[0024] like Figures 1 to 8As shown, the present invention is a rotatable and adjustable three-point magnetic reverse push safety buckle, which mainly consists of two parts: a male buckle 1 and a female buckle 2. The male buckle 1 and the female buckle 2 are assembled together through the movable engagement of the tongue 22 with the annular groove 106 and the magnetic interaction between the magnets. It is worth noting that the pressing member 22 in the female buckle 2 is provided with a third mounting hole 243 and a fourth mounting hole 244. These two magnet mounting holes are arranged side by side, and the magnetic poles of the third magnet 240 and the fourth magnet 241 installed in these two magnet mounting holes are opposite to each other. The purpose of this design is that when the pressing member 22 is pressed to unlock the buckle, the fourth magnet 241, which was originally attracted to the first magnet 104, is pushed forward, and is replaced by the third magnet 240 that repel the first magnet 104. The first magnet 104 is installed in the first magnet mounting hole 101, which is a cavity for fixing the guide post 100. In addition to the above-mentioned first magnet 104, third magnet 240 and fourth magnet 241 as a group to achieve the coordinated work of magnetic attraction and reverse push, the utility model is also provided with a group of magnets to increase flexibility and practicality, namely the second magnet 105 and the fifth magnet 112. The second magnet 105 is installed in the second magnet mounting hole 102 of the left buckle 10, and the fifth magnet 112 is installed in the fifth magnet mounting hole 110 of the right buckle 11. It should be noted that the second magnet 105 and the fifth magnet 112 are aligned and embedded based on the principle of opposites attracting each other. After the left buckle 10 and the right buckle 11 are assembled to form the male buckle 1, the fifth magnet 112 should be located above the second magnet 105 to maximize the magnetic force, thereby playing a guiding role when the left buckle 10 and the right buckle 11 are blindly fixed, and playing a reinforcing role during assembly and use. This role and effect are also the same for the first magnet 104 and the fourth magnet 241. Such a design can greatly increase the flexibility of the user when operating with one hand.

[0025] The general description of the present invention is as follows: the male buckle 1 includes a left buckle part 10 and a right buckle part 11; the left buckle part 10 is integrally formed with a fixed guide column 100, a first magnet mounting hole 101, a second magnet mounting hole 102 and an auxiliary countersunk hole 103, while the right buckle part 11 is integrally formed with an auxiliary protrusion 111 and a fifth magnet mounting hole 110 for embedding the fifth magnet 112; the female buckle 2 includes a shell composed of an upper cover 20 and a base 21, and a tongue 22, a return spring 23 and a pressing member 24 with a magnet assembled in the shell; the pressing member 24 is designed with two magnet mounting holes for embedding the third magnet 240 and the fourth magnet 241 respectively; the female buckle 2, the left buckle part 10 and the right buckle part 11 are each formed with a lace groove 3; a through hole is provided at the bottom of the base 21 to allow the fixed guide column 100 of the male buckle 1 to be inserted and work in conjunction with the tongue 22.

[0026] Furthermore, in order to enable the female buckle 2 of the present invention to be rotatably adjusted on the male buckle 1, the fixed guide post 100 is formed with an annular groove 106 to cooperate with the tongue 22. Compared with the traditional design, the female buckle 2 and the male buckle 1 do not have a mutually restrictive or locking structure, so the female buckle 2 can be rotatably adjusted 360° on the male buckle 1.

[0027] Furthermore, to ensure the stability of the present invention during daily use and prevent the magnets from falling out due to shaking during use, all magnet mounting holes are equipped with plugs to increase the stability of the magnet assembly, preventing the loosening of the buckle due to the magnet falling out, which could endanger the user's personal safety. Similarly, auxiliary protrusions 111 and auxiliary mounting countersunk holes 103 are also used to strengthen the connection. These two are designed to be positioned relative to each other, allowing the left and right buckle parts 10 and 11 to be assembled and fixed together, further increasing the strength and safety of the present invention.

[0028] To facilitate assembly or disassembly and maintenance, the upper cover 20 and the base 21 are integrally formed with an undercut 200 and a buckle position 210 respectively. The two can be assembled and fixed by interlocking, which can reduce assembly time and manpower in the production process. During use, when a single component is damaged, it can be disassembled and replaced without loss, saving use costs and increasing service life to a certain extent.

[0029] Regarding the upper cover 20 and the base 21, it can be further explained that the upper cover 20 is also formed with a guide rail 201 to assist the tongue 22 with the return spring to perform directional movement after being installed in position, so as to prevent it from derailing and failing, which affects the fastening, and the inner cavity of the base 21 is also symmetrically designed with a fixing slide groove to install the tongue 22 equipped with the return spring. It is also formed with a guide rail groove and a limit baffle to assist the pressing member in directional installation and movement limitation, ensuring that the tongue 22, the pressing member 24 and the return spring can work stably in the housing in which they are assembled. Of course, in order to ensure that the return spring does not bounce away from the set direction during the resetting and extension process, the tongue 22 is provided with a countersunk hole to assemble its spring, and the pressing member 24 is integrally formed with a positioning column 245 for its positioning sleeve. Such a design is reasonable and simple.

[0030] It is worth mentioning that the bottom of the pressing member 24 is designed with an inclined push surface 242 that cooperates with the tongue 22. When the pressing member 24 is gradually pressed forward, it can smoothly and gradually compress the tongue 22 to make the unlocking and buckling action smooth, and also allow the third magnet 240 to move to the top of the first magnet 104 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 other one-button release effects that are only fast but not stable.

[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 of the 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. Of course, the utility model can also be used like Figure 9 The same five-point magnetic buckle design can also meet the needs of use in more occasions.
