Fig. 1 shows a schematic structural view of a safety zipper slider according to an embodiment of the present invention. Fig. 2 is a schematic structural view of a slide fastener body according to an embodiment of the present invention. Fig. 3 shows a schematic structural diagram of a pull tab according to an embodiment of the present invention. As shown, a safety slider 100 mainly includes a slider body 101 and a pull tab 102.

The zipper body 101 has a hollow cavity 103. A locking piece 104 and a return spring 107 are provided in the hollow cavity 103. One side of the locking piece 104 protrudes out of the hollow cavity 103 and forms a pressing portion 105. The return spring 107 is disposed between the other side of the locking piece 104 and the inner wall of the zipper body 101. The locking piece 104 is provided with a locking portion 106. The fastener body 101 is provided with a through hole 108.

The pull tab 102 has a snap ring 109. The retaining ring 109 can extend into the through hole 108 and form a fastening structure with the fastening portion 106.

When the buckle 106 and the buckle 109 are engaged with each other, the fastener body 101 and the tab 102 are coupled, and the safety slider 100 is in a locked state, and the tab 102 cannot be separated from the fastener body 101. When the pressing portion 105 of the fastener 104 is pressed, the latch portion 106 moves to the right side in the hollow cavity 103 along the paper surface, the return spring 107 is pressed, the latch portion 106 is naturally released from the snap ring 109, the safety slider 100 is turned to the release state, the pull tab 102 is lifted, and the pull tab 102 can be separated from the slider 101. At this time, the pressing portion 105 is released, and the latch portion 106 moves to the left side along the paper surface in the hollow cavity 103 as a whole by the return pressure of the return spring 107, and returns to the initial position.

Preferably, one end of the return spring 107 abuts against the other side of the locking piece 104, and the other end of the return spring 107 abuts against the inner wall of the slide fastener body 101.

Preferably, the other side of the locking element 104 projects outwardly with a guide post 110. One end of the return spring 107 is fitted over the guide post 110. The guide post 110 has a guiding function, so that the return spring 107 does not deviate from the original position in the compression and release processes, and the return effectiveness of the return spring 107 is ensured. Further, a pair of stoppers 111 is provided on the inner wall of the fastener body 101. The other end of the return spring 107 falls between a pair of flaps 111. The pair of flaps 111 further limit the possibility of the return spring 107 from deviating from the guide post 110 from the space, enhancing the return effectiveness of the return spring 107.

Preferably, the end of the snap 106 is inwardly inclined. When the snap ring 109 of the pull tab 102 is inserted, the snap ring 109 applies a downward force to the buckling portion 106, and the buckling portion 106 is inclined inward, so that a component force in the lateral direction of the return spring 107 is applied to the buckling portion 106, which is equivalent to partially pressing the pressing portion 105 of the locking piece 104, and the snap ring 109 and the buckling portion 106 can be easily buckled.

Preferably, the safety zipper puller 100 further includes a slider 112 having a safety locking function. The slider 112 is provided on the fastener body 101, and is engaged with a wall surface of the fastener body 101 and movable in the longitudinal direction of the fastener body 101. The slider 112 forms a latch 113 at one side extending into the hollow cavity 103, and the latch 113 can slide into between the other side of the locking element 104 and the inner wall of the zipper body 101. Referring to fig. 3, the slider 112 reaches the locking position, and the latch 113 is located between the other side of the locking member 104 and the inner wall of the slide fastener body 101. At this time, by pressing the fastener 104, the fastener 104 can move only slightly to the right or cannot move at all, and the stroke of the fastener 104 is limited, so that the hook 106 and the hook 109 are kept in the engaged state, and the tab 102 cannot be disengaged from the fastener body 101. The slider 112 functions as a safety lock. When the slider 112 is pressed downwards, the slider 112 moves downwards, the latch 113 moves away from the space between the other side of the locking element 104 and the inner wall of the zipper body 101, thus releasing the stroke of the locking element 104, the pressing part 105 of the locking element 104 is pressed again, the locking element 104 moves rightwards to press the return spring 107, the buckling part is separated from the retaining ring 109, the pull tab 102 is lifted, and the safety zipper head 100 enters a release state.

Preferably, the surface of the slider 112 is formed with a corrugated protrusion, which can increase the friction when pushing and pressing the slider 112, thereby facilitating the operation and the up-and-down movement of the slider 112.

The utility model provides a pair of draw zipper head safely, it is fixed through hasp piece and pulling-on piece cooperation, press the hasp piece and can easily open locking structure, whole convenient operation and excellent in use effect.

It will be apparent to those skilled in the art that various modifications and variations can be made to the above-described exemplary embodiments of the present invention without departing from the spirit and scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
