Description

Technical Field

[0001] The present invention relates to the technical field of buckles, and in particular to a magnetic buckle and a product using the magnetic buckle. Background Art

[0002] A buckle is a connector used to connect or separate two parts. Buckles are widely used in daily life, such as bags, clothing, safety gear, etc. The buckle forms used vary according to different usage requirements. Among them, magnetic buckles are becoming more and more popular due to the special physical feeling brought by magnetic attraction.

[0003] In the current design of magnetic buckles, in addition to using magnetic attraction to achieve fastening and fixing, related locking structures are usually set up to assist, so as to ensure the stability of the magnetic buckle. However, in the design of many magnetic buckles, the magnetic attraction part and the locking part do not cooperate well with each other. On the one hand, there are deficiencies in the design planning between the two, and on the other hand, the design of the related locking structure is not good. It is easy to have problems such as poor operability, locking failure, and easy deformation and damage during use.

[0004] In view of this, the inventor of this case conducted in-depth research on the above-mentioned problems and proposed a magnetic buckle and a product using the magnetic buckle, which resulted in this case. Summary of the invention

[0005] The object of the present invention is to provide a magnetic buckle and a product using the magnetic buckle, which has a simple and reliable structural design, a flexible buckling method, and excellent buckling performance, avoiding poor buckling problems such as sticking, loosening, and deviation.

[0006] In order to achieve the above object, the solution of the present invention is:

[0007] A magnetic buckle comprises a first slider, a second slider and a clamping piece; the first slider and the second slider have a first clamping portion and a second clamping portion that are clamped together; the first clamping portion has a first magnetic area and a cavity area, and a first magnet is installed in the first magnetic area; the cavity area is provided with a buckle cavity, and the buckle cavity has openings formed on two adjacent sides of an L shape, and the openings include a transverse opening and a longitudinal opening; two corresponding card grooves are provided on the inner side surfaces of the two opposite side walls of the buckle cavity, and the two card grooves are extended transversely and arranged on the side close to the transverse opening, and one end of the two card grooves is an opening end extending to the longitudinal opening; the second clamping portion has a second magnetic area and a clamping area, and a second magnet for mutual magnetic attraction with the first magnet is installed in the second magnetic area; the clamping piece is installed in the clamping area, and the clamping piece is provided with two clamping heads corresponding to the two card grooves.

[0008] The clamping member comprises a connecting plate and two vertical plates formed side by side on the plate surface of the connecting plate, and the clamping heads are formed on the outer plate surfaces of the two vertical plates which are opposite to each other.

[0009] A through groove for installing a card member and penetrating through both sides is formed on the card area. The connecting plate of the card member is installed on the groove wall of the through groove close to the second magnetic area, and the two vertical plates are suspended in the through groove without contact.

[0010] Pressing limit parts are formed at both ends of the connecting plate, and pressing limit grooves for correspondingly and matingly installing the pressing limit parts are formed at both ends inside the through groove.

[0011] Two notches that divide the connecting plate into three independent parts are provided at positions close to both ends of the connecting plate. Both ends of the two notches respectively extend to the two vertical plates, forming an elastic adjustment opening in a "冂" shape.

[0012] The elastic adjustment opening also constitutes a limiting notch, and a limiting convex block matching the limiting notch is formed inside the through groove.

[0013] Another object of the present invention is also to provide a product using a magnetic buckle, and the above-mentioned magnetic buckle is used on the product.

[0014] The product is a luggage, shoes, clothing, toy or baby stroller.

[0015] After adopting the above scheme, the beneficial effects of the magnetic buckle of the present invention compared with the prior art are as follows:

[0016] First, the magnetic buckle includes three main parts: a first slider (female buckle), a second slider (male buckle) and a card member. The card member is designed independently of the first slider (female buckle) and the second slider (male buckle), and is installed on the second slider (male buckle). The card slot is relatively concealed on the first slider (female buckle), and the card member is more exposed and unobstructed on the second slider (male buckle), which is conducive to alignment and clamping operations and avoids the problem of concealed jamming.

[0017] Second, the card member is designed independently of the first slider and the second slider, and its two card heads are integrally designed on the same card member. Therefore, compared with the prior art directly integrally formed on the magnetic buckle, the elastic adjustability of the two card heads of the card member in this application is better, and the internal stresses between the two card heads interact with each other, improving the cooperation effect between the two card heads and avoiding the deviation and misalignment of any one of the card heads, which may affect the overall buckling performance.

[0018] Third, the buckling parts of the sliders are magnetic areas and card areas arranged side by side longitudinally, so the magnetic attraction part and the card-making part of the magnetic buckle are designed in a longitudinally separated manner. The corresponding magnetic attraction force and card-making force are designed to be relatively spread out flatly on the buckling part. In this way, the buckling force of the mutual buckling part of the first slider and the second slider is reasonably spread out, which is equivalent to the uniform spreading of the buckling force, bringing a better overall buckling performance and avoiding defects such as easy loosening and instability.

[0019] 4. In the magnetic snap-on operation of the present application, it is only necessary to move the second snap-on portion of the second slider toward the opening position of the first slider (which can be a horizontal opening, a longitudinal opening, or a position between the two). When it is extended to a certain close distance, under the mutual magnetic attraction of the first magnet and the second magnet, the second slider and the first slider are aligned with each other, and at the same time, the card slot and the card head limit each other to achieve the magnetic snap-on operation; when the magnetic snap is separated, it is only necessary to slide the second slider outward from the longitudinal opening to achieve simple separation of the magnetic snap, and the operation is very simple.

[0031] The case is further described in detail below in conjunction with specific implementation methods.

[0032] This case involves a magnetic buckle, such as Figure 1-4 As shown, it mainly includes a first slider 1, a second slider 2 and a clamp 3. The first slider 1 has a first buckling portion, and the second slider 2 has a second buckling portion; the first slider 1 and the second slider 2 are magnetically buckled with each other through the first buckling portion and the second buckling portion. The side-by-side direction of the first slider 1 and the second slider 2 in the buckled state is the longitudinal direction, and the direction perpendicular to the longitudinal direction is the transverse direction.

[0033] The first fastening portion of the first slider 1 has a first magnetic region 1a and a cavity region 1b distributed longitudinally. A first magnet 4 is installed in the first magnetic region 1a. Specifically, a receiving groove 11 is provided on the first magnetic region 1a, and the first magnet 4 is fitted and installed in the receiving groove 11. The cavity region 1b is provided with a fastening cavity 12. Specifically, the fastening cavity 12 can be isolated from the receiving groove 11 by a partition, so as to facilitate the magnetic attraction function of the first magnet 4. The fastening cavity 12 has openings formed on two adjacent sides in an L shape, and the openings include a transverse opening 121 and a longitudinal opening 122. Corresponding two card slots 123 are provided on the inner side surfaces of the opposite two side walls of the fastening cavity 12. The two card slots 123 extend transversely and are arranged on the side close to the transverse opening 121 (so that the clamping part and the magnetic attraction part of the magnetic buckle are designed to be spread out as much as possible), and one end of each of them is an open end extending to the longitudinal opening 122.

[0034] The second fastening portion of the second slider 2 has a second magnetic region 2a and a clamping region 2b distributed longitudinally. A second magnet 5 is installed in the second magnetic region 2a. Specifically, a receiving groove 12 is provided on the second magnetic region 2a, and the second magnet 5 is fitted and installed in the receiving groove 12. When the second fastening portion and the first fastening portion are fastened to each other, the whole second fastening portion is correspondingly inserted into the fastening cavity 12 of the first fastening portion, and then the second magnetic region 2a and the first magnetic region 1a are arranged in a directly opposite and adjacent manner, so that the second magnet 5 and the first magnet 4 have an effective magnetic attraction effect on each other.

[0035] The card member 3 is installed in the clamping region 2b, and the card member 3 is provided with two card heads 321 corresponding to and cooperating with the two card slots 123. In order to facilitate the smooth insertion of the card heads 321 into the fastening cavity 12 to achieve the mutual clamping and limiting effect with the card slots 123, the outer sides of the card heads 321 are designed to be inclined. As a preferred embodiment of the card member 3, the card member 3 has a connecting plate 31 and two vertical plates 32 formed side by side on the plate surface of the connecting plate 31. The card heads 321 are formed on the outer side surfaces of the two vertical plates 32 facing away from each other. The two vertical plates 32 are arranged vertically and are connected by the same connecting plate 31. Therefore, the two vertical plates 32 can play an excellent elastic adjustment role and a mutual restraint cooperation effect.

[0036] Preferably, in order to strengthen the connection and restraint effect between the two vertical plates 32 of the card member 3, two notches that divide the connecting plate 31 into three independent parts are provided at positions close to both ends of the connecting plate 31. The two ends of the two notches respectively extend to the two vertical plates 32, forming a U-shaped elastic adjustment opening 311. Through the elastic adjustment opening 311, the connecting plate 31 plays a better role in connecting the two vertical plates 32, and the mutual restraint effect of the two vertical plates 32 is more prominent.

[0037] Preferably, the installation method of the card 3 on the card area 2b is that a through groove 22 penetrating on both sides is formed on the card area 2b, and the connecting plate 31 of the card 3 is installed on the corresponding groove wall of the through groove 22 close to the second magnetic area 2a. The two vertical plates 32 are suspended in the through groove 22 without contact. Specifically, the two vertical plates 32 are at least completely accommodated in the through groove 22, and the clamping head 321 on the outer plate surface extends out of the through groove 22, so as to achieve mutual clamping effect with the card groove 123. Such a design ensures the simplicity and compactness of the structural design of the card 3, while also being able to exert flexible clamping performance. The operation is simple and fast, and the hand feel is excellent.

[0038] Furthermore, the connection plate 31 is installed in the through groove 22 in such a manner that the two ends of the connection plate 31 are formed with compression limiting portions 312, and the two ends of the through groove 22 are formed with compression limiting grooves 222 for the compression limiting portions 312 to be installed in a corresponding manner. The assembly is very simple and convenient, and stable and firm.

[0039] Preferably, the elastic adjustment opening 311 is also configured as a limiting notch, and a limiting protrusion 221 matching the limiting notch is formed in the groove penetrating the groove 22. Under the premise of not affecting the connection and restraining effect between the two vertical plates 32 (the direction in which the two vertical plates 32 are arranged side by side), the limiting protrusion 221 plays a certain limiting and reinforcing role on the structural stability of the three independent parts of the connecting plate 31 (the direction in which the three parts are arranged side by side), and strengthens the structural stability of the entire clamp 3.

[0040] In the magnetic buckle fastening operation of the present application, it is only necessary to move the second fastening portion of the second slider 2 toward the opening position of the first slider 1 (which can be the horizontal opening 121, the longitudinal opening 122, or the position between the two), and when it is extended to a certain close distance, under the mutual magnetic attraction of the first magnet 4 and the second magnet 5, the second slider 2 and the fastening portion of the first slider 1 are mutually aligned and inserted, and the first magnet 4 and the second magnet 5 are closely magnetically attracted to each other, and at the same time, the card slot 123 and the card head 321 are mutually limited, so that the overall magnetic buckle is reliably and firmly fastened. When the magnetic buckle is separated, it is only necessary to slide the second slider 2 outward from the longitudinal opening 122 to realize the simple separation of the magnetic buckle, which is very simple to operate.

[0041] The magnetic buckle of the present application includes three parts: a first slider 1, a second slider 2 and a clamp 3, wherein the first slider 1 is equivalent to a female buckle, the second slider 2 is equivalent to a male buckle, the clamp 3 is independently designed from the first slider 1 and the second slider 2 and installed on the male buckle, and the clamping slot 123 is relatively concealed on the female buckle. The internal structure of the female buckle is very simple, and only the clamping slot 123 needs to be designed, which avoids cumbersome assembly and facilitates production. The clamp 3 is relatively exposed and not covered on the male buckle, which is not only conducive to assembly, but more importantly, it is relatively visible to the outside, which is conducive to alignment and engagement operations during use, and can also well avoid the hidden jamming problem that is easy to occur in the female buckle during the engagement operation, affecting normal use and user experience.

[0042] The clamping component 3 of the present application is designed to be independent of the first slider 1 and the second slider 2, and its two clamping heads 321 are integrally designed on the same clamping component 3 through two vertical plates 32. Therefore, compared with the existing direct integral molding on the magnetic buckle body, the two clamping heads 321 of the clamping component of the present application have better elastic adjustability, and the internal stresses between the two clamping heads 321 interact with each other, thereby improving the mutual coordination effect between the two clamping heads 321 and avoiding the possibility that any of the clamping heads may deviate from the position and affect the overall buckle performance.

[0043] The respective buckling parts of the first slider 1 and the second slider 2 of the present application are two areas distributed side by side longitudinally, and the two areas are distinguished by the magnetic attraction part and the clamping part of the corresponding magnetic buckle, that is, the magnetic attraction part and the clamping part of the magnetic buckle are designed to be separated longitudinally, and the corresponding magnetic attraction force and the clamping force are designed to be relatively flat on the buckling part, so that the buckling force of the mutually buckling parts of the first slider 1 and the second slider 2 is reasonably spread out, which is equivalent to the uniform spreading of the buckling force, bringing better overall buckling performance and avoiding defects such as looseness and instability in areas far away from the action of the buckling force.

[0044] The present invention also provides a product using a magnetic buckle, which uses the magnetic buckle described above, which will not be described in detail here. The product can be any object that needs to use a magnetic buckle, such as bags, shoes, clothing, toys or baby strollers.
