Description
Technical Field
[0001] This utility model relates to the field of zipper technology, specifically to a zipper opening block pin device. Background Technology
[0002] A zipper consists of several parts: a chain strip, teeth that engage with the side of the chain strip, a zipper head, a zipper block, and a pin. The zipper block grips the chain strip under one side of the teeth, and the zipper head fits onto the teeth on that side. To use it, insert the pin, which is fixed to the chain strip on the other side, into the zipper head and zipper block on that side, and pull the zipper head upwards to engage the teeth on both sides.
[0003] The blocks used in the existing technology are directly connected to the chain fabric and cannot be disassembled separately. If the blocks and pins fail to engage during use, the entire zipper will become unusable. Furthermore, the connection between the pins and blocks in the existing technology is not very secure, and the pins are prone to coming loose from the bottom of the zipper during use, causing the entire zipper to come loose.

The fixed block 1 is provided with a locking mechanism 4 for fixing the opening block 2, and a reinforcing mechanism 5 is provided between the opening block 2 and the pin 3. The locking mechanism 4 includes two sets of movable frames 401 symmetrically distributed within the fixed block 1. The two sets of movable frames 401 are movably engaged with the opening block 2, and each set of movable frames 401 is fitted with a compression spring 403. Each set of movable frames 401 is fixedly fitted with a slider 404, and the two sets of movable frames 401 are slidably connected to the fixed block 1 through the slider 404. Each set of movable frames 401 is fixedly mounted with a rack 402. The reinforcing mechanism 5 includes two sets of... The side plates 501 are distributed on both sides of the pin 3. Both sets of side plates 501 are rotatably connected to the pin 3 through the mounting shaft 502. Both sets of side plates 501 are provided with locking blocks 504. Two sets of fixing rods 505 are symmetrically distributed on both sides of the open block 2. The two sets of locking blocks 504 are respectively set with the two sets of fixing rods 505. The zipper is fixedly installed with the zipper fabric through the fixed block 1. The installation of the open block 2 on the fixed block 1 is completed by the locking mechanism 4. When the open block 2 is damaged during use, the opening block 2 can be replaced through the locking mechanism 4 to extend the service life of the overall zipper. The connection between the pin 3 and the open block 2 is reinforced by the reinforcement mechanism 5 to prevent the zipper from coming loose from the pin 3 and the open block 2 during use.
[0027] In this embodiment, reference Figure 2 , Figure 3 As shown, a mounting rod 405 is provided inside the fixing block 1, and the mounting rod 405 passes through the fixing block 1 and is rotatably connected to the fixing block 1 through a bearing. A gear 406 is sleeved on the mounting rod 405, and the gear 406 is respectively meshed with two sets of racks 402. A first torsion spring 407 is sleeved on the mounting rod 405, and the two ends of the first torsion spring 407 are respectively fixedly connected to the gear 406 and the fixing block 1. A first bevel gear 408 is sleeved on the mounting rod 405. A handle is provided inside the fixing block 1, and the handle passes through the fixing block 1 and is rotatably connected to the fixing block 1 through a bearing. A fourth torsion spring 411 is sleeved on the handle, and the two ends of the fourth torsion spring 411 are respectively fixedly connected to the handle and the fixing block 1. The handle and the mounting rod 405 are perpendicularly distributed. A second bevel gear 410 is sleeved on the handle, and the second bevel gear 410 is meshed with the first bevel gear 408. When using this zipper, the fixing block 1 is first fixedly installed with the zipper fabric. By turning the handle, the second bevel gear 410 is driven to rotate, and the first bevel gear 408, which meshes with it, causes the mounting rod 405 to rotate. The gear 406 on the mounting rod 405 rotates synchronously. The two sets of racks 402, which mesh with the gear 406, move synchronously to both sides under the action of the gear 406, and drive the two sets of moving frames 401 to move synchronously to both sides. The opening block 2 is inserted into the fixing block 1. The handle is released, and under the action of the first torsion spring 407, the fourth torsion spring 411, and the compression spring 403, the two sets of moving frames 401 are destroyed in their original positions, completing the snap-fit fixation with the opening block 2. The opening block 2 can be easily removed from the fixing block 1. If there is a problem with the opening block 2, it can be replaced in time, extending the service life of the entire zipper.

The two sets of clips 507 are rotatably connected to the fixing rod 505, and the two sets of clips 507 are movably engaged with the corresponding clips 504. Two sets of symmetrically distributed third torsion springs 506 are sleeved on the fixing rod 505, and the two ends of the third torsion springs 506 are respectively connected to the fixing rod 505 and the clips. 507 is fixedly connected. After the opening block 2 is installed, press the two sets of side plates 501 so that the right end of the two sets of side plates 501 is away from the pin 3, and the pin 3 is engaged with the opening block 2. Release the side plates 501. Under the action of the second torsion spring 503, the two sets of side plates 501 move closer to the opening block 2 at the same time. The locking block 504 is inserted between the corresponding two sets of locking brackets 507. Under the action of the third torsion spring 506, the two sets of locking brackets 507 fix the locking block 504, and the connection between the pin 3 and the opening locking block 504 is reinforced to prevent the pin 3 from coming loose from the opening block 2 during the use of the zipper.

By rotating the handle, the second bevel gear 410 is driven to rotate, and the first bevel gear 408, which meshes with it, causes the mounting rod 405 to rotate. The gear 406 on the mounting rod 405 rotates synchronously. The two sets of racks 402, which mesh with the gear 406, move synchronously to both sides under the action of the gear 406, and drive the two sets of moving frames 401 to move synchronously to both sides. The opening block 2 is inserted into the fixing block 1. The handle is released, and under the action of the first torsion spring 407, the fourth torsion spring 411, and the compression spring 403, the two sets of moving frames 401 are knocked back into their original positions, completing the snap-fit fixation with the opening block 2. The opening block 2 can be fixed in place. The fixed block 1 can be easily disassembled, and the opening block 2 can be replaced in time if there is a problem, thus extending the service life of the entire zipper. After the opening block 2 is installed, press the two sets of side plates 501 so that the right end of the two sets of side plates 501 is away from the pin 3, and the pin 3 is engaged with the opening block 2. Release the side plates 501 and under the action of the second torsion spring 503, the two sets of side plates 501 move closer to the opening block 2 at the same time. The locking block 504 is inserted between the corresponding two sets of card holders 507, and under the action of the third torsion spring 506, the two sets of card holders 507 fix the locking block 504, thus reinforcing the connection between the pin 3 and the opening locking block 504 and preventing the pin 3 from coming loose from the opening block 2 during the use of the zipper.
