The unlocking direction refers to a rotation direction which enables the self-locking piece to release the self-locking state in the conventional sense.
As shown in fig. 2 to 5, a slider for a self-locking slide fastener comprises a slider body 2 and a self-locking member for a self-locking slide fastener as described above;
a pull piece stop block 201 is arranged on the slider body 2, one end of the pull piece stop block 201 is fixedly connected with the slider body 2, a gap for a pull rod of the pull piece 4 to pass through is formed between the other end of the pull piece stop block 201 and the slider body 2, and a cavity 202 for arranging a self-locking piece is arranged on the pull piece stop block 201;
the self-locking piece is arranged in the cavity 202 and hinged with the pull piece stop block 201, an elastic piece 3 is arranged between the self-locking piece and the sliding block body 2, and a through hole 203 is formed in the sliding block body 2;
the elastic piece 3 forms acting force for rotating the self-locking piece in the self-locking direction on the self-locking pushing part 104, under the acting force of the elastic piece 3, the abutting part 102 abuts against the slider body 2 or the pull piece stop block 201, the hook part 103 penetrates through the through hole 203, and the edge of the pull piece limiting groove 105 is positioned between the pull piece stop block 201 and the slider body 2;
the self-locking piece can rotate towards the unlocking direction under the pulling action of the pulling piece until the edge of the pulling piece limiting groove 105 is positioned at the edge of the pulling piece stop 201 close to one side edge of the slider body 2, and when the edge of the pulling piece limiting groove 105 is positioned at the edge of the pulling piece stop 201 close to one side edge of the slider body 2, the hook part 103 is positioned in the through hole 203 or positioned between the pulling piece stop 201 and the slider body 2;
the guide push inclined surface 106 is arranged close to the gap formed between the pull-tab stopper 201 and the slider body 2, and when the pull tab is pushed in along the guide push inclined surface 106, the self-locking member rotates around the hinge portion 101 in the unlocking direction, and finally the opening of the pull-tab limiting groove 105 faces the gap formed between the pull-tab stopper 201 and the slider body 2.
When the pull tab is installed, as shown in fig. 5, when the pull tab is pushed in from the left side of the slider in fig. 5, the pull rod of the pull tab penetrates through the gap formed between the pull tab stopper 201 and the slider body 2 to abut against the guide pushing inclined surface 106, and when the pull tab is pushed in again, the pull rod and the guide pushing inclined surface 106 interact to enable the self-locking piece to rotate around the hinge center in the direction of releasing the locking state (namely, clockwise direction in the figure), so that the opening of the pull tab limiting groove 105 faces the gap formed between the pull tab stopper 201 and the slider body 2, and the pull rod can slide into the pull tab limiting groove 105 along the guide pushing inclined surface 106. Therefore, the pull piece can be quickly installed under the condition of no tool, the operation is simple and quick, the production efficiency is improved, and the production cost is reduced.
Specifically, the hinge portion 101 is a circular hole, an opening 204 for allowing a self-locking element to enter the cavity 202 is formed in the pull-tab stop 201, a hinge hole 205 for allowing a hinge post to pass through is formed in the pull-tab stop 201, and the self-locking element is connected with the pull-tab stop 201 in a hinged mode through the hinge post. In this embodiment, the self-locking element is a sheet structure, and the opening 204 of the pull tab stopper 201 for the self-locking element to enter the cavity 202 is also adapted to the width of the self-locking element, so that the structure is compact, and the self-locking element is not easily touched during use. The hinge 101 may also be a structure with hinge posts.
In this embodiment, as shown in fig. 4 and 5, a spring retaining groove 206 communicating with the cavity 202 is formed in the slider body 2, the elastic member 3 is a compression spring, and the elastic member 3 is disposed in the spring retaining groove 206. The self-locking pushing function of the self-locking piece can also be learned by adopting the structure of the torsion spring.
As shown in fig. 1, the self-locking element includes a connecting portion 107 provided with a hinge portion 101, and a first arm 108 and a second arm 109 extending outward from the connecting portion 107, a pull-tab limiting groove 105 is formed between the first arm 108 and the second arm 109 in a recessed manner, and at least a portion of the first arm 108 away from an outer side surface of the pull-tab limiting groove 105 and/or at least a portion of the second arm 109 away from an outer side surface of the pull-tab limiting groove 105 is an abutting portion 102.
Specifically, as shown in fig. 4, a first abutting surface 207 and a second abutting surface 208 for forming surface contact are respectively disposed in the through hole 203 corresponding to the outer side surface of the first support arm 108 away from the pull-tab limiting groove 105 and the outer side surface of the second support arm 109 away from the pull-tab limiting groove 105. When the self-locking element is in a self-locking state, as shown in fig. 5, the outer side surface of the first support arm 108 away from the pull-tab limiting groove 105 is in surface contact with the first abutting surface 207, and the outer side surface of the second support arm 109 away from the pull-tab limiting groove 105 is in surface contact with the second abutting surface 208, so that the self-locking element is more stable.
Specifically, the second arm 109 is located on one side of the first arm 108 that rotates in the self-locking direction, that is, the second arm 109 is located relatively on the inner side, and a hook is formed at an end of the second arm 109 as the hook portion 103. The end of the first arm 108 located relatively on the outer side may be the hook 103, that is, the end of the first arm 108 in fig. 5 extends downward to the lower side of the through hole 203, so that the rotation angle of the self-locking element is relatively larger when the pull tab is installed or removed, the operation time is increased, the efficiency is reduced, and the inclination of the guiding and pushing slope 106 is required to be larger.
The pull tab stopper 201 has a locking hole 209 for a padlock. As shown in fig. 7, the locking hole portion 209 is used to connect and lock two self-locking sliders, and serves as an anti-theft function, and can be used as a zipper used for a bag. In the figures, the tab stopper 201 is provided with one latch hole portion 209, and the tab stopper 201 may be provided with two latch hole portions 209, both of which are conventional in the art.
A self-locking zipper puller comprises a slider and a pull tab 4, wherein the slider and the pull tab 4 are used for the self-locking zipper, the pull tab 4 comprises a pull rod 401, and the pull rod 401 is located in a pull tab limiting groove 105.
A self-locking zipper is provided with the self-locking zipper puller.
