Quick-detachable zipper slider

Abstract

A quick-detachable zipper slider includes a first clamping plate, a second clamping plate, and an elastic pin assembly. The first clamping plate is extended towards the second clamping plate to form a connecting part, the second clamping plate is pivotally connected to the connecting part, and the second clamping plate has a clamping position and a releasing position. The connecting part has a locking hole, and the elastic pin assembly is located on the second clamping plate and has a movable pin. When the second clamping plate is in the clamping position, the pin is inserted into the locking hole, and the pin is withdrawn from the locking hole to allow the first clamping plate to rotate relative to the second clamping plate. The zipper slider has easy assembly and simple structure.

What is claimed is: 
     
         1 . A quick-detachable zipper slider, comprising a first clamping plate, a second clamping plate, and an elastic pin assembly, wherein the first clamping plate is extended towards the second clamping plate to form a connecting part, and the second clamping plate is pivotally connected to the connecting part, thereby enabling the second clamping plate to rotate relative to the first clamping plate to provide a clamping position and a releasing position; the connecting part is provided with a locking hole, the elastic pin assembly is located on the second clamping plate, and the elastic pin assembly has a movable pin used for locking; when the second clamping plate is in the clamping position, the pin is inserted into the locking hole to lock a rotation between the first clamping plate and the second clamping plate, and the pin is withdrawn from the locking hole to allow the first clamping plate to rotate relative to the second clamping plate. 
     
     
         2 . The quick-detachable zipper slider according to  claim 1 , wherein the elastic pin assembly further comprises a guide rod and a spring element, the guide rod is fixed to the second clamping plate, the pin is slidably arranged on the guide rod and provides an extended position for inserting into the locking hole and a retracted position for exiting the locking hole, the spring element is compressed between the second clamping plate and the pin, the spring element is further fitted over the guide rod, and the spring element provides an elastic force that constantly urges the pin to move from the retracted position to the extended position. 
     
     
         3 . The quick-detachable zipper slider according to  claim 2 , wherein the second clamping plate has a through hole corresponding to the pin for allowing the pin to pass through, the through hole is arranged along a length direction of the second clamping plate, the guide rod and spring element are installed in the through hole, the pin is slidably arranged in the through hole, and when the second clamping plate is in the clamping position, the through hole is aligned with the locking hole. 
     
     
         4 . The quick-detachable zipper slider according to  claim 3 , wherein the second clamping plate has a detent hole corresponding to the pin, the detent hole is connected to the through hole, the pin extends towards the detent hole to form a detent part, when the detent part engages with the detent hole, the pin locks in the retracted position by overcoming an elastic force of the spring element, and when the detent part disengages from the detent hole, the pin locks in the extended position under an action of the spring force of the spring element. 
     
     
         5 . The quick-detachable zipper slider according to  claim 4 , wherein the detent hole comprises a longitudinal hole and a lateral hole, the longitudinal hole is connected to the lateral hole and is perpendicular to each other, both the longitudinal hole and the lateral hole are connected to the through hole, a contour of the lateral hole is matched with that of the detent part, and the detent part is selectively engaged with the lateral hole or disengaged from the lateral hole, by rotating the pin. 
     
     
         6 . The quick-detachable zipper slider according to  claim 3 , wherein the elastic pin assembly further comprises a screw, and the guide rod is installed in the through hole through the screw. 
     
     
         7 . The quick-detachable zipper slider according to  claim 1 , wherein the first clamping plate is symmetrically provided with a left protruding block and a right protruding block, and a zipper track groove that is matched with the second clamping plate is formed between the left protruding block and the right protruding block. 
     
     
         8 . The quick-detachable zipper slider according to  claim 1 , wherein the first clamping plate is provided with a loop. 
     
     
         9 . The quick-detachable zipper slider according to  claim 1 , wherein the second clamping plate is pivotally connected to the connecting part through a pivot shaft.
