Description

Technical Field

[0001] This application relates to the technical field of snap fasteners, and particularly to a magnetic snap fastener. Background Art

[0002] A webbing buckle is a snap fastener that is convenient for snapping. It is commonly installed on travel bags and suitcases. By mutually snapping two main bodies respectively connected with webbing, the bundling of objects is realized, which is very simple and fast compared with the traditional knotting and fixing.

[0003] However, when the existing webbing buckles on the market are in use, they usually require two-handed operation. When snapping, it is necessary to hold one main body with each hand and insert one main body into the side of the other main body for snapping. When unlocking, it is necessary to press the unlock with one hand and cooperate with the other hand to pull out one main body from the other main body. Therefore, it is very inconvenient in some emergency situations or when it is inconvenient to use both hands. Utility Model Content

[0004] This application provides a magnetic snap fastener to at least solve the technical problem that the webbing buckle in the related art is not convenient for single-handed operation.

[0008] In some of these embodiments, the first magnetic member is disposed near the locking member body at the end of the clamping portion, the second magnetic member and the third magnetic member are both disposed on the locking member body, and when the locking member is locked with the clamping portion, the first magnetic member and the second magnetic member are in corresponding positions and attract each other, and the third magnetic member is disposed on a side of the second magnetic member away from the second clamping end.

[0009] In some of these embodiments, a fourth magnetic member that corresponds to and attracts the third magnetic member in position during locking is disposed on a side of the first magnetic member away from the first clamping end, and / or, a fourth magnetic member that corresponds to and repels the second magnetic member in position during unlocking is disposed on a side of the first magnetic member close to the first clamping end.

[0010] In some of these embodiments, the moving distance of the second clamping end in the direction away from the first clamping end is at least the distance between the side of the second magnetic member away from the second clamping end and the side of the third magnetic member away from the second clamping end.

[0011] In some of these embodiments, the second body is provided with a switch member at least partially exposed on the outside, and the switch member is in transmission connection with the locking member and can drive the locking member to move inside the second body.

[0012] In some of these embodiments, the switch member is hinged to the second body and abuts against an end of the locking member body away from the second clamping end, and pressing the switch member can cause the second clamping end to move in the direction away from the first clamping end.

[0013] In some of these embodiments, the shape of the second clamping end matches that of the first clamping end, and the first clamping end and the second clamping end are respectively provided with inclined surfaces that can cooperate with each other and abut against each other to facilitate mutual clamping and locking.

[0014] In some of these embodiments, an elastic member is disposed on a side of the locking member away from the first clamping end, and the elastic member causes the second clamping end to have a tendency to reset after moving away from the first clamping end.

[0015] According to the above, the beneficial effects of the technical solution of the present application compared with the prior art are:

[0016] 1. Compared with traditional webbing buckles, in the present application, the second body is provided with a clamping groove at the bottom. When clamping, only the second body needs to be covered on the protruding clamping portion of the first body, and it can be clamped and locked by pressing with one hand.

[0028] This application provides a magnetic snap fastener, which includes a first body and a second body that are engaged and snapped together. The first body is provided with a protruding engaging portion, and a first magnetic member is arranged on the engaging portion. The second body is provided with an engaging groove capable of accommodating the engaging portion, and a movable locking member is arranged inside the second body. The locking member is provided with a second magnetic member that attracts the first magnetic member when locked and a third magnetic member that repels the first magnetic member when unlocked.

[0029] As shown in the embodiment Figures 1 to 4 A magnetic snap fastener includes a first body 1 and a second body 2 that are engaged and snapped together. The first body 1 is provided with a cylindrical engaging portion 1.1 protruding upward, and the lower end of the second body 2 is provided with an engaging groove 2.1 matching the shape of the engaging portion 1.1. The engaging portion 1.1 can be accommodated in the engaging groove 2.1 to achieve the mutual engaging and snapping cooperation between the first body 1 and the second body 2.

[0030] Specifically, a first clamping end 1.1.1 is provided on the side of the clamping part 1.1. A movable locking member is provided inside the second main body 2. The locking member includes a locking member main body 3.1 and a second clamping end 3.2. The locking member main body 3.1 is arranged at the end of the clamping groove 2.1 and cooperates with the top of the clamping part 1.1. The second clamping end 3.2 is arranged on the side of the locking member main body 3.1 close to the clamping part 1.1 and extends towards the first clamping end 1.1.1, corresponding to the position of the first clamping end 1.1.1. The first clamping end 1.1.1 and the second clamping end 3.2 can cooperate and be clamped with each other.

[0031] Further, a switch member 4 which is at least partially exposed outside is provided at the upper end of the second main body 2. The switch member 4 is hinged on the second main body 2 and abuts against one end of the locking member main body 3.1 far from the second clamping end 3.2. The locking member main body 3.1 is provided with an arc surface which cooperates with the switch member 4. Pressing the switch member 4 can make the second clamping end 3.2 move away from the first clamping end 1.1.1 in the second main body 2. An elastic member (the elastic member can be a spring, not shown in the figure of the present application) which abuts against the inside of the second main body 2 is provided on the side of the locking member far from the first clamping end 1.1.1. The elastic member makes the second clamping end 3.2 have a tendency to reset after moving away from the first clamping end 1.1.1. Pressing the switch member 4 can make the switch member 4 push the locking member and then drive the second clamping end 3.2 away from the first clamping end 1.1.1 to realize the unlocking of the locking member and the clamping part 1.1; the elastic member pushes the locking member to reset and then drives the second clamping end 3.2 close to the first clamping end 1.1.1 to realize the locking of the locking member and the clamping part 1.1.

[0032] Further, a first magnetic member 1.2 is provided at the top of the clamping part 1.1 close to the locking member main body 3.1. A second magnetic member 3.3 and a third magnetic member 3.4 which can cooperate with the first magnetic member 1.2 are provided on the locking member main body 3.1. The second magnetic member 3.3 can attract the first magnetic member 1.2, and the third magnetic member 3.4 can repel the first magnetic member 1.2. The second magnetic member 3.3 and the third magnetic member 3.4 are arranged in parallel side by side on the locking member main body 3.1, and the third magnetic member 3.4 is arranged on the side of the second magnetic member 3.3 far from the second clamping end 3.2.

[0033] Further, a fourth magnetic member (not shown in the figure) is also provided at the top of the clamping portion 1.1 near the main body 3.1 of the locking member. The fourth magnetic member can be arranged on the side of the first magnetic member 1.2 away from the first clamping end 1.1.1 and correspond to the position of the third magnetic member 3.4 in the locked state, and the third magnetic member 3.4 can attract the fourth magnetic member; alternatively, the fourth magnetic member can be arranged on the side of the first magnetic member 1.2 close to the first clamping end 1.1.1 and correspond to the position of the second magnetic member 3.3 in the unlocked state, and the second magnetic member 3.3 can repel the fourth magnetic member; or, based on the above arrangement, the fourth magnetic member can be arranged on both sides of the first magnetic member 1.2 at the same time.

[0034] Specifically, the distance that the second clamping end 3.2 moves away from the first clamping end 1.1.1 until it completely disengages from the first clamping end 1.1.1 is at least the distance between the side of the second magnetic member 3.3 away from the second clamping end 3.2 and the side of the third magnetic member 3.4 away from the second clamping end 3.2. The second magnetic member 3.3 and the third magnetic member 3.4 are spaced 1 mm apart, and the first magnetic member 1.2, the second magnetic member 3.3, the third magnetic member 3.4, and the fourth magnetic member have the same specifications and a width of 4 mm each. Then, the moving distance of the second clamping end 3.2 in the direction away from the first clamping end 1.1.1 is at least 5 mm.

[0035] Taking the case where the fourth magnetic member is arranged on both sides of the first magnetic member 1.2 as an example, when the locking member and the clamping portion 1.1 are locked in the clamping groove 2.1, the second magnetic member 3.3 corresponds to the first magnetic member 1.2 and attracts each other, and the third magnetic member 3.4 attracts the fourth magnetic member located on the side away from the first clamping end 1.1.1, providing an additional adsorption force for the locking member and the clamping portion 1.1 to prevent them from disengaging during the clamping process. When the switch member 4 is pressed to push the locking member to move and thus unlock the locking member and the clamping portion 1.1, the second magnetic member 3.3 gradually moves away from the first magnetic member 1.2 and the third magnetic member 3.4 gradually approaches the first magnetic member 1.2. When the second clamping end 3.2 completely disengages from the first clamping end 1.1.1, at this time, the third magnetic member 3.4 completely corresponds to the first magnetic member 1.2 and repels each other, and the second magnetic member 3.3 repels the fourth magnetic member located on the side close to the first clamping end 1.1.1, providing an additional repulsive force for the locking member and the clamping portion 1.1 to make the first main body 1 and the second main body 2 bounce off each other.

[0036] Specifically, the first magnetic member 1.2, the second magnetic member 3.3, the third magnetic member 3.4, and the fourth magnetic member can be magnets.

[0037] Further, the second clamping end 3.2 is a semi-circular arc structure whose shape matches that of the first clamping end 1.1.1. The first clamping end 1.1.1 and the second clamping end 3.2 are respectively provided with inclined surfaces that can cooperate and abut against each other. The semi-circular arc structure and the inclined surfaces facilitate the mutual clamping and locking of the first clamping end 1.1.1 and the second clamping end 3.2 only by continuing to press after the clamping portion 1.1 is inserted into the clamping groove 2.1.

[0038] Further, connecting portions 5 for connecting the webbing are respectively provided on the first main body 1 and the second main body 2.

[0039] Working principle: During use, the second main body 2 is covered on the first main body 1, so that the clamping portion 1.1 of the first main body 1 is inserted into the clamping groove 2.1 of the second main body 2. Press the second main body 2 to engage and lock the first clamping end 1.1.1 of the clamping portion 1.1 with the second clamping end 3.2 of the locking member. At this time, the second magnetic member 3.3 and the first magnetic member 1.2 attract each other, and the second magnetic member 3.3 also plays a role of adsorption and positioning during the process of the clamping portion 1.1 being inserted into the clamping groove 2.1. When unlocking, press the switch member 4, and the switch member 4 pushes the locking member to move so that the second clamping end 3.2 disengages from the first clamping end 1.1.1. At the same time, the third magnetic member 3.4 corresponds to and repels the first magnetic member 1.2, causing the first main body 1 and the second main body 2 to bounce open.
