Description

Technical Field

[0001] This utility model relates to the field of daily life, and in particular to a fastener with magnetic attraction function. Background Technology

[0002] Keychains, also known as key rings, key chains, key hangers, etc., are a primary tool used to facilitate the carrying of keys and are everyday items that people carry with them. Keychains come in a variety of shapes and sizes, but they typically use an elastic device to tightly connect an arc-shaped hook and a sealing hook to form a complete closed loop, allowing the keychain to be hung on a belt without falling off.

[0003] Patent No. ZL201720442951.3 discloses a keychain that allows keys or small objects to be suspended on a carrier with a rope-like or rod-like structure, facilitating the carrying of small objects. However, for carriers without a rope-like or rod-like structure, it is impossible to suspend and carry small objects, reducing the effectiveness of the buckle product. Therefore, it is necessary to improve it. Summary of the Invention

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a simple and convenient fastener with magnetic attraction function.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A fastener with magnetic attraction function includes a fastener body, which can be configured in various shapes. The fastener body has a hollow cavity structure inside, and a magnet is embedded in the hollow cavity structure so that the fastener can achieve a magnetic connection effect through the magnetic attraction property of the magnet.

[0007] Furthermore, the fastener includes a main fastener, a movable fastener, or an elastically deformable opening. Both the main fastener and the movable fastener can be of various shapes. The key is that they can be combined to form a closed, enclosed hollow structure.

[0008] Furthermore, the magnets embedded in the fastener can be assembled using various methods, such as spaced-out drilling or slotted arrangement. They are then sealed with adhesive or secured with a magnetic sealing sheet to prevent them from falling out. This also prevents direct contact and friction between the magnets and the objects they attract.

[0009] Furthermore, the magnetic function can be applied to various types of fasteners. For example, there are various methods to achieve the opening and closing of closed structures, such as compression spring return type, elastic material deformation type, magnetic type, return type, and composite multi-material combination type. As long as a magnet is embedded, the magnetic function can be achieved.

[0010] Furthermore, the buckle can be used in conjunction with some personal items or small household products such as card holders, power banks, mobile phone cases, keychains, car keychains, chargers, and mobile phone stands to achieve buckle suspension and magnetic suspension effects for the connected items.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are:

[0012] This invention employs a hollow cavity structure with magnets embedded within it. This design allows the buckle to be connected to a rope-like or rod-like object via the enclosed space of the main buckle, movable buckle, or deformable opening. Alternatively, the magnetic attraction of the magnets within the buckle allows it to be directly attached to an object attracted to the magnets. This enables small personal and everyday items such as cardholders, power banks, phone cases, keychains, car keychains, chargers, and phone holders to be suspended from various structures, expanding the range of hanging and carrying options. It eliminates the need to hold the items, improving portability and the buckle's multi-functionality. Furthermore, this invention boasts a simple structure and low cost.

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, any other embodiments obtained by those skilled in the art without creative effort, including any copying, modification, equivalent substitution, improvement, etc., should be included within the protection scope of this utility model.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiments listed herein disclose a fastener with magnetic attraction function, including a fastener body. The fastener body is composed of a main fastener 1 and a movable fastener 2. Both the main fastener 1 and the movable fastener 2 are in the shape of an arc ring. The arc length of the main fastener 1 is greater than the arc length of the movable fastener 2. One end of the main fastener 1 and one end of the movable fastener 2 are connected by a pin to form a closed ring structure.

[0019] A first receiving groove 101 is provided on one end face of the main fastener 1. The first receiving groove 101 is arranged along the length direction of the main fastener 1. A plurality of first magnets 5 are embedded in the first receiving groove 101. The plurality of first magnets 5 are arranged sequentially along the circumference direction of the main fastener 1. The plurality of first magnets 5 are connected end to end by magnetic means. A second receiving groove 201 is provided on one end face of the movable fastener 2. A second magnet 6 is embedded in the second receiving groove 201. The main fastener 1 and the movable fastener 2 can achieve a magnetic connection effect through the magnetic attraction properties of the first magnets 5 and the second magnets 6. At the same time, when the main fastener and the movable fastener are in the closed state, the first magnets and the second magnets attract each other, making the closed structure between the main fastener and the movable fastener more stable.

[0020] A first sealing sheet 3 is fixedly connected to the outside of the first receiving groove 101 of the main fastener 1 to block the first magnet 5, so as to prevent the first magnet 5 from falling out of the first receiving groove 101; a second sealing sheet 4 is fixedly connected to the outside of the second receiving groove 201 of the movable fastener 2 to block the second magnet 6, so as to prevent the second magnet 6 from falling out of the second receiving groove 201; the sealing sheet can be made of various materials or structures. It can be firmly assembled together with the main fastener by bonding or other assembly methods, which can prevent the magnet from falling out of the receiving groove and also prevent the magnet from directly contacting and rubbing against the adsorbed object.

[0021] One end of the main fastener 1 has a first connecting ear 102, and one end of the movable fastener 2 is integrally formed with two second connecting ears 202. The first connecting ear 102 is inserted between the two second connecting ears 202 and connected by a fixing pin 7 to realize the relative rotation between the main fastener 1 and the movable fastener 2.

[0022] The main fastener 1 is provided with a first limiting slope 103 at the end away from the first connecting ear 102, and the movable fastener 2 is provided with a second limiting slope 203 that is adapted to the first limiting slope 103 at the end away from the second connecting ear 202.

[0023] When the main fastener 1 and the movable fastener 2 are in the closed state, the first limiting inclined surface 103 abuts against the second limiting inclined surface 203; an elastic element is provided between the end of the main fastener 1 near the first connecting ear 102 and the end of the movable fastener 2 near the second connecting ear 202, so that the first limiting inclined surface 103 on the main fastener 1 abuts against the second limiting inclined surface 203 on the movable fastener 2 under the action of elasticity, so as to realize the closed holding state of the main fastener 1 and the movable fastener 2.

[0024] When the movable fastener 2 rotates and the main fastener 1 and movable fastener 2 are in the open state, the elastic element is compressed or the magnets attracting the main fastener 1 and movable fastener 2 are separated, creating an opening gap between the first limiting inclined surface 103 and the second limiting inclined surface 203. When connected to a rope-like or rod-like structure, the rope or rod structure is inserted through the opening gap. After the movable fastener 2 is released, the two are re-closed under the attraction of the elastic element or the magnets embedded in the main fastener 1 and movable fastener 2, ultimately achieving the connection operation between the fastener and the load.

[0025] The buckle body in this utility model can be the aforementioned spring buckle, magnetic buckle, or various other types of buckles such as open buckles, deformable buckles, and U-shaped buckles. After installing a magnet through the hollow cavity, it can achieve the same technical effect. In use, the buckle body structure can function as a standalone product or connect to small objects via pins, shafts, screws, or other connecting methods. Finally, the buckle body can be attached to a magnetically attractive support or suspended from a rope-like or rod-like support, thus achieving the placement or carrying effect of small objects. These small objects can be personal items such as card holders, power banks, phone cases, keychains, car keychains, chargers, and phone stands, or other small everyday items. All of these can achieve the hanging and carrying effects of snapping, magnetic attraction, etc., through the buckle body in this utility model.

[0026] This invention employs a hollow cavity structure for the buckle body, with magnets embedded within it. This design allows the buckle body to be connected to a rope-like or rod-like structure via the enclosed space of the main and movable fasteners, or directly attached to a magnet-attracting object using the magnetic attraction of the magnets within the buckle body. This enables small items such as cardholders, power banks, phone cases, keychains, car keychains, chargers, and phone holders to be suspended from various structures, expanding the range of hanging and carrying options for these items. It eliminates the need to hold the items by hand, improving portability and enhancing the buckle's versatility.
