Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a side-opening magnetic quick-release buckle. Background Technology

[0002] A buckle is a mechanical structure in which one part is embedded and connected to another or is closed as a whole. It is very common in daily life and is often seen on the straps of backpacks, baby carriers, cameras and other items, where it serves to fix them. Due to different application scenarios and customer needs, many different types of buckles have been developed, such as push-motion buckles, slide-motion buckles and magnetic buckles, to meet different usage needs.

[0003] Due to the fragility of cameras and their outdoor use, they are often carried on straps to protect them and facilitate portability. To make the strap connection more convenient, a buckle is used to connect the camera and the strap. At the same time, the camera will shake constantly during outdoor use and has a certain weight, requiring the buckle to have good connection strength to withstand large pulling forces. In addition, the buckle also needs to be easy to disassemble and reassemble, thus making the camera and other equipment more flexible in operation. Utility Model Content

[0004] The purpose of this invention is to provide a side-opening magnetic quick-release buckle.

[0005] To achieve the purpose of this utility model, a side-opening magnetic quick-release buckle is provided, including a buckle base, a buckle member, and a button. The buckle base has a slot along the vertical direction. A movable section and a locking section are respectively connected at the upper and lower ends of the slot. A through-hole is provided through the locking section vertically downwards. A bottom wall is provided on the inner side of the slot. A wide opening is provided on the outer side of the movable section, and a narrow opening is provided on the outer side of the locking section. The width of the wide opening is greater than or equal to the diameter of the buckle member, and the width of the narrow opening is less than the diameter of the buckle member. The buckle is located at the bottom. A lanyard is provided, and a magnet is installed on the top of the buckle. The buckle is installed from the wide opening through the movable section to the locking section, and the lanyard passes through the through opening. The button includes a latch, a pressing part, and a spring part. The spring part is connected to the buckle seat. The pressing part is used to drive the latch away from the buckle, and the spring part is used to drive the latch closer to the buckle. In the locked state, the latch is adjacent to the buckle and restricts the vertical movement of the buckle. In the unlocked state, the latch is separated from the buckle, and the buckle moves vertically toward the movable section under the action of magnetism.

[0006] As can be seen from the above scheme, the fastener can be inserted into the movable section through the wide opening, and the lanyard can be inserted into the locking section through the narrow opening. In the locked state, the fastener's vertical movement is restricted by the locking tongue. The narrow opening width, combined with the gravity of the object after the lanyard is hung, provides a stable locking force for the fastener. In the unlocked state, the locking tongue is driven to separate from the fastener, and the fastener moves vertically toward the movable section under magnetic force. The wide opening width allows the fastener and lanyard to be easily removed from the slot, enabling convenient and quick disassembly.

[0007] A further improvement is that the buckle has an assembly groove on the side of the slot, and a through groove is provided between the assembly groove and the locking section. The button is installed in the assembly groove, and the locking tongue can move through the through groove to be adjacent to the fastener.

[0008] A further proposed solution is to mount the button in the mounting slot via a pivot, with the pressing part located at the upper end of the pivot and the locking tongue at the lower end, and the pressing part and the locking tongue rotating around the pivot respectively.

[0009] A further proposed solution is to use a torsion spring as the elastic part, with the rotating shaft passing through the winding part of the torsion spring, and the two ends of the torsion spring connected to the pressing part and the buckle respectively.

[0010] A further improvement is that the fastener is equipped with a locking groove, and the locking tongue can be detachably engaged with the locking groove.

[0011] As can be seen above, the button is rotatably assembled into the mounting slot via a pivot, and a torsion spring is used to provide the reset force and locking force, which improves the ease of locking and unlocking operations, and makes the button pressing and rotating more stable.

[0012] A further proposed solution is to use magnetic attraction between the fastener and the top of the movable section, with the magnet positioned at the upper end of the fastener and / or the top of the movable section.

[0013] As can be seen from the above, there are various ways and positions to arrange magnets, and the purpose of this case can be achieved through the arrangement of magnetic attraction.

[0014] A further proposed solution is to have a fixing groove at the top of the movable section, which is isolated from the card slot. A first magnet is installed inside the fixing groove and is located at the top of the movable section. The fastener and the first magnet are magnetically attracted to each other.

[0015] A further proposed solution is to have a second magnet at the upper end of the fastener, which magnetically attracts the first magnet.

[0016] A further improvement is that the fixing groove is provided with a magnetic opening, which is arranged in the opposite direction to the wide opening, and part of the first magnet is located at the magnetic opening.

[0017] As can be seen from the above, there are various ways and positions to arrange the magnets. The fixed slot can be used to isolate and protect the first magnet. The magnetic attraction on the back allows the first magnet to not only be magnetically attracted to the second magnet, but also to be magnetically connected to other hanging objects or fixed objects.

[0018] A further solution is to provide mounting slots on opposite sides of the card slot, and the magnetic quick-release buckle includes two buttons, one of which is installed in the mounting slot on one side.

[0019] As can be seen above, the locking force of the fasteners can be increased by using the buttons on both sides. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0029] First embodiment of magnetic quick-release buckle:

[0030] Reference Figures 1 to 5The magnetic quick-release buckle includes a buckle base 1, a fastener 2, and two buttons 3. The buckle base 1 has a slot 11 arranged vertically. The upper and lower ends of the slot 11 are respectively connected to a movable section 111 and a locking section 113. The locking section 113 has a through-hole 115 arranged vertically downward. The slot 11 has a bottom wall 10 arranged on the inner side. The movable section 111 has a wide opening 112 arranged on the outer side. The locking section 113 has a narrow opening 114 arranged on the outer side. The width of the wide opening 112 is greater than or equal to the diameter of the fastener 2, and the width of the narrow opening 114 is less than the diameter of the fastener 2. The locking section 113 has a receiving platform 116 on both sides of the through-hole 115, which is used to support the fastener 2.

[0031] The buckle 1 has a first connecting groove 118 and a second connecting groove 119 above the card slot 11. The first connecting groove 118 and the second connecting groove 119 are used to connect different shoulder straps or lanyards. The top of the movable section 111 has a fixing groove 121, which is isolated from the card slot 11. The fixing groove 121 has a first magnet 21, which is located at the top of the movable section 111. The fixing groove 121 has a magnetic opening, which is arranged in the opposite direction to the wide opening 112. The first magnet 21 can be installed into the fixing groove 121 through the magnetic opening. Part of the first magnet 21 is located at the magnetic opening, and part of the first magnet 21 can attract and fix shoulder straps or other fixed objects.

[0032] The buckle 1 has mounting grooves 120 on opposite sides of the slot 11. A button 3 is installed in the mounting groove 120 on one side. Specifically, a through groove 117 is provided between the mounting groove 120 and the locking section 113. The button 3 includes a latch 32, a pressing part 31, a connecting part 33, and an elastic part. The connecting part 33 is connected between the latch 32 and the pressing part 31. The hinge hole 331 of the connecting part 33 is installed in the hole 122 of the mounting groove 120 through a rotating shaft 34. The pressing part 31 is located at the upper end of the rotating shaft 34, and the latch 32 is located at the lower end of the rotating shaft 34. The pressing part 31 and the latch 32 rotate around the rotating shaft 34 respectively. The elastic part is a torsion spring 35. The rotating shaft 34 passes through the winding part of the torsion spring 35. The two ends of the torsion spring 35 are connected to the pressing part 31 and the buckle 1 respectively. The latch 32 movably passes through the through groove 117.

[0033] The fastener 2 is arranged in a columnar shape. A hanging rope 23 is provided at the bottom of the fastener 2. A locking groove 22 is provided in the middle of the fastener 2, which extends circumferentially. A second magnet 4 is provided at the upper end of the fastener 2.

[0034] Reference Figure 4 , Figure 4 (a) is a sectional view along the left-right direction. Figure 4(b) is a cross-sectional view along the front-back direction. The fastener 2 is installed from the wide opening 112 to the movable section 111, and the hanging rope 23 is installed from the narrow opening 114 to the locking section 113. By pulling down the fastener 2, the fastener 2 is installed from the movable section 111 to the locking section 113. The hanging rope 23 passes through the through opening 115. In the locked state, the locking tongue 32 can move through the through groove 117 and engage with the locking groove 22. The torsion spring 35 is used to drive the locking tongue 32 to move closer to the fastener 2, thereby providing locking force to the locking tongue 32.

[0035] Reference Figure 5 , Figure 5 (a) is a sectional view along the left-right direction. Figure 5 (b) is a cross-sectional view along the front-back direction. When it is necessary to unlock the fastener 2 and enter the unlocked state, the pressing part 31 is pressed, which drives the locking tongue 32 to rotate. The locking tongue 32 separates from the fastener 2. Due to the magnetic attraction between the second magnet 4 and the first magnet 21, the fastener 2 moves vertically toward the movable section 111 under the action of magnetism. The first magnet 21 is adjacent to the top of the movable section 111, and then the fastener 2 can be easily removed.

[0036] Second embodiment of magnetic quick-release buckle:

[0037] Following the same principle as the first embodiment, the arrangement of the magnets can be changed, as shown below. Figures 6 to 8 A third magnet 41 is provided at the top of the movable section 111. The third magnet 41 is used to magnetically attract the first magnet 21 of the fastener 2. A fixing groove is provided at the top of the third magnet 41. A fourth magnet 42 is provided in the fixing groove. Part of the fourth magnet 42 is exposed and arranged facing the back side.

[0038] The main objective of this case can be achieved through the magnetic attraction between the third magnet 41 and the first magnet 21.

[0039] Of course, the above embodiments are only preferred embodiments of this invention. There are many variations in the arrangement of the magnets. For example, a magnet can be placed on the top of the fastener, or on the top of the slot. Both arrangements allow the fastener to move vertically upwards under magnetic attraction when unlocked. Alternatively, a magnet can be placed on the fastener or on the top of the slot. Correspondingly, the top of the slot or the fastener can be made of metals such as iron, nickel, or cobalt, or have magnetic suction plates made of such metals. These arrangements also achieve the magnetic attraction effect and fulfill the purpose of this invention. Furthermore, the button can be arranged not only on both sides for locking, but also on one side or the rear. All of these arrangements can lock the fastener. In addition to the locking tongue engaging with the fastener to lock it, the locking tongue can also be positioned adjacent to the top or other parts of the fastener, thus restricting the vertical movement of the fastener.

[0040] As can be seen from the above, in the locked state, the locking tongue restricts the vertical movement of the fastener. Then, by utilizing the narrow opening width and the gravity of the object after being hung on the lanyard, a stable locking force is provided for the fastener. In the unlocked state, by driving the locking tongue to separate from the fastener, the fastener moves vertically towards the movable section under the action of magnetism. Utilizing the wider opening width, the fastener and lanyard can be easily removed from the slot, so as to achieve convenient and quick disassembly.
