Detailed Description

The invention is described below with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 7, a double-slider magnetic zipper mechanism comprises a zipper 1, a first slider 2 arranged on the zipper 1, a second slider 3 arranged on the zipper 1, and an unlocking mechanism 4 arranged at one end of the zipper 1.

The bottom of the first pull head 2 is provided with a locking assembly, the locking assembly comprises a locking cover 5 fixedly arranged at the bottom of the first pull head 2, a magnet 6 arranged in the locking cover 5 and a locking plate 7 arranged in the locking cover 5, the locking plate 7 is made of iron, the locking plate 7 is hinged in the locking cover 5, and the magnet 6 is arranged above the locking plate 7 and used for sucking the locking plate 7.

The bottom of the second pull head 3 is provided with an insertion part 8, in the process that the first pull head 2 and the second pull head 3 are close to each other, the insertion part 8 acts on the locking plate 7 to rotate around the hinge to the direction away from the magnet 6 so as to be clamped into the locking assembly, specifically, the insertion part 8 is arranged at one end of the second pull head 3 close to the first pull head 2, the insertion part 8 comprises a first plug board 9 arranged at the bottom of the second pull head 3 and a second plug board 10 arranged at the bottom of the first plug board 9, and the bottom boards of the first plug board 9, the second plug board 10 and the second pull head 3 form an I-shaped piece.

As shown in fig. 1, 5, and 7, a first insertion hole 11 is formed in one end of the locking cover 5 close to the second slider 3, an open slot is formed above the first insertion hole 11, two sides of the open slot form clamping plates 12 for clamping two sides of an i-shaped part respectively, a stopper 13 for preventing the insertion portion 8 located in the first insertion hole 11 from moving out of the first insertion hole 11 is arranged at one end of the locking plate 7 close to the first insertion hole 11, the locking plate 7 includes a first plate body 14, two second plate bodies 15 arranged at two intervals at one end of the first plate body 14 close to the first insertion hole 11, an insertion portion accommodating area 30 is formed between the two second plate bodies 15, the stopper 13 is arranged at one end of the second plate body 15 far away from the first plate body 14 and connected to the end portions of the two second plate bodies 15, and. When the inserting part 8 overcomes the magnetic force of the magnet 6 on the locking plate 7 and is clamped into the locking assembly, the first slider 2 and the second slider 3 are abutted, the clamping plates 12 on the two sides limit the second slider 3 to move left and right and turn up and down, and the stop 13 limits the second slider 3 to move in the direction far away from the first slider 2.

As shown in fig. 4-6, the unlocking mechanism 4 is disposed at the end of the slide fastener 1 on the side of the first slider 2 away from the second slider 3, the unlocking mechanism 4 includes a fixed block 17, an unlocking block 18 disposed on the side of the fixed block 17 and protruding toward the extending direction of the slide fastener 1, and a lock sleeve (not shown) rotatably mounted on the fixed block 17, the locking plate 7 further includes a trigger block 20 disposed at the end of the first plate 14 away from the stop 13, the bottom of the trigger block 20 is an inclined wall 21, when unlocking is required, the first slider 2 is moved to a position close to the unlocking mechanism 4, the unlocking block 18 is inserted into the bottom of the trigger block 20 and causes the stop 13 at the other end of the locking plate 7 to rotate around the hinge and release the blocking of the insertion portion 8, at this time, the first slider 2 and the second slider 3 can be separated from each other, the lock sleeve is disposed outside the unlocking block 18 in a rotating, therefore, the unlocking block 18 and the trigger block 20 can be isolated from being contacted to unlock.

In addition, the invention also provides an unlocking method adopting the double-head magnetic zipper mechanism, which comprises the following steps:

(1) as shown in fig. 5 and 6, the first slider 2 and the second slider 3 are close to each other, and the insertion part 8 of the second slider 3 overcomes the magnetic force of the magnet 6 on the locking plate 7 and is clamped into the locking assembly, so that the first slider 2 and the second slider 3 are locked;

(2) and moving the first slider 2 and the second slider 3 to the end part of the zipper 1 on one side of the first slider 2, inserting the unlocking block 18 into the bottom of one end of the locking plate 7 far away from the second slider 3, rotating the stop 13 at the other end of the locking plate 7 around the hinge joint and releasing the block of the inserting part 8, and unlocking between the first slider 2 and the second slider 3.

By adopting the technical scheme, the first slider 2 and the second slider 3 are close to each other, the inserting part 8 of the second slider 3 overcomes the magnetic force of the magnet 6 on the locking plate 7 and is clamped into the locking assembly, and the locking between the first slider 2 and the second slider 3 is realized. Therefore, at the middle position of the zipper 1, the first slider 2 and the second slider 3 are close to each other, so that the locking can be completed, and a good anti-theft effect is achieved.

When the unlocking is needed, the first pull head 2 and the second pull head 3 are moved to the end part of the zipper 1 on one side of the first pull head 2, a lock head does not need to be additionally arranged, and the unlocking is convenient and fast.

In addition, the implementation mode that the locking plate adopts the elastic sheet is further designed, the elastic force of the elastic sheet is used for locking, the mode that the locking plate is attracted by the magnet is compared with the mode that the locking plate adopts the elastic sheet, in the test, the mode that the locking plate is attracted by the magnet is adopted, the attraction force can be set to be smaller by adopting the magnet with small magnetic force, and therefore, the locking of the two pull heads can be completed only by pulling the other pull head of one pull head which is in a free state relatively to move. The locking plate adopts a spring plate mode, the elasticity is large, one pull head is in a free state, the other pull head is pulled to be close to the other pull head, the locking cannot be reliably locked, the two pull heads need to be further pulled to move relatively to complete the locking, if in batch production, the elasticity of the spring plate is uneven, the consistency is difficult to control, and the locking plate is not suitable for mass production.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications, combinations and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
