Description

TECHNICAL FIELD

[0001] The present application relates to the field of zippers, in particular to a type of anti-jamming metal zipper. BACKGROUND

[0002] The zipper includes a zipper head and a zipper tape, and the material of the teeth on the zipper tape can be classified as nylon zipper, metal zipper and plastic zipper. The zipper tape has two tapes, and the bottom of each tape is provided with a stopper and a plug respectively. The zipper head is slidably arranged on the tape on the side of the stopper. The zipper head is provided with a stop edge, and a receiving cavity for accommodating the teeth on the zipper tape is formed between the stop edge and the zipper head. The cloth seam is provided for the zipper tape to pass through. When the zipper is to be closed, the zipper head is first slid to the bottom stopper, and then the plug of the other zipper tape is inserted into the insertion slot of the stopper through the receiving cavity on the side of the zipper head. Then the zipper head can be pulled upwards, so that the teeth on the two zipper tapes are interlaced and "sewn" together.

[0003] The zipper head is further provided with a locking member and a spring. The locking member has a pivotable end, and the pivotable end is provided with a downwardly extending hook portion. The spring is used to press the locking member, so that the hook portion of the locking member can be located between the interlaced teeth on both sides, thereby positioning the position of the zipper head on the zipper tape. The end of the pull tab is sleeved on the locking member, and the locking member can be pulled upwards against the elastic force of the spring, so that the hook portion of the locking member is pulled out from between the teeth.

[0004] The hook portion of the locking member is located in the receiving cavity in the zipper head for the two sides of the teeth to pass through. During normal use, the plug inserted into the receiving cavity on the side of the zipper head will lift the hook portion upwards. However, due to the production size accuracy and sewing process accuracy of the plug, some plugs are not lifted when inserted, but are stuck between the hook portion of the locking member and the stop edge, making it difficult for the plug to smoothly pass into the insertion slot of the stopper, affecting use. CONTENT OF THE UTILITY MODEL

[0005] In order to solve the above technical problems, the present application provides a type of anti-jamming metal zipper.

[0006] The anti-jamming metal zipper provided by the present application adopts the following technical scheme:

[0007] The anti-jamming metal zipper includes a plug, a stopper and a zipper head. The stopper is provided with an insertion slot for inserting the plug. The zipper head is rotatably provided with a locking member. The side of the plug close to the stopper is provided with a top member. The top member is used to abut and lift the hook portion of the locking member.

[0008] By adopting the technical scheme, when the plug is inserted into the accommodating cavity of the zipper head, the hook portion of the locking member is abutted by the top member and is lifted up, so that the plug is prevented from being clamped between the locking member and the blocking edge, and the production and fixing precision requirements of the plug are reduced.

[0009] Optionally, the top member comprises an extension edge extending away from the connection between the plug and the zipper tape, the stop member is provided with a clearance slot for accommodating the extension edge, and the zipper head is provided with an avoiding slot for the extension edge to pass through.

[0010] By adopting the technical scheme, the extension edge is convenient and simple in structure and convenient to process, the extension edge is inserted and matched with the clearance slot and the avoiding slot, and the hook portion of the locking member is lifted up without interference with the zipper head and the stop member.

[0013] Optionally, the top member comprises a top block which is telescopically arranged on the plug and is telescopically arranged in a direction close to or away from the connection between the plug and the zipper tape.

[0014] By adopting the technical scheme, the top block is telescopically arranged on the plug, so that the top block does not need to be accommodated by being slotted on the zipper head and the stop member.

[0015] Optionally, the plug is provided with a telescopic slot, the top block is slidingly arranged in the telescopic slot, a top elastic member is arranged between the top block and the inner wall of the telescopic slot, and the top elastic member is used to push the top block to move out of the telescopic slot to abut against the hook portion of the locking member.

[0016] By adopting the technical scheme, the top block is telescopically moved by the top elastic member.

[0017] Optionally, the top block is provided with a recovery surface which is used to abut against the stop member or the zipper head to drive the top block to retreat into the telescopic slot.

[0018] By adopting the technical scheme, the user only needs to pass the plug through the zipper head and insert it into the stop member, without other operations, the top block is automatically collected into the telescopic slot through the recovery surface, and the user is convenient to operate.

[0019] Optionally, the elastic force of the top elastic member is greater than the elastic force of the elastic sheet.

[0020] By adopting the technical scheme, the situation that the top block retreats into the telescopic slot without lifting the hook part of the locking member is avoided, and it is ensured that the bolt cannot be stuck between the locking member and the retaining edge.

[0021] Optionally, the stopper is formed with a recovery slope, which is arranged to be inclined towards the direction close to the bolt in the direction of guiding the top block to retreat into the telescopic slot.

The telescopic direction of the clamping block is perpendicular to the movement direction of the zipper head, so as to adapt to the size of the fabric seam opening.

[0024] By adopting the technical scheme, when the user pulls the zipper, the retaining edge may be stuck to the clothes. At this time, the telescopic clamping block can increase the size of the fabric seam opening, so that the clothes stuck can be taken out, and the damage to the clothes and the situation that the clothes are stuck are avoided.

[0025] Optionally, a sliding groove is formed in the retaining edge, the clamping block is slidingly arranged in the sliding groove, a reset elastic member is arranged between the clamping block and the inner wall of the sliding groove, and the reset elastic member is used to push the clamping block to move out of the sliding groove.

[0026] By adopting the technical scheme, when the clothes are stuck by the retaining edge, the clothes can be taken out. In the process of taking out the clothes, the clamping block will automatically retreat into the sliding groove, which is convenient to operate.
