A zipper, which is a commonly used accessory for an opening portion of a garment, generally includes a pair of fastener tapes and a slider sliding on the pair of fastener tapes to control the pair of fastener tapes to close or open. The pull head comprises a main body and a pull piece which is arranged on the main body in a reversible mode, and sliding of the pull head can be controlled by pulling the pull piece. Since the pull tab is often flexible to flip, the pull tab frequently collides with the main body to make annoying noise when a wearer wearing the clothes with the zipper moves. The utility model discloses a provide a plastic steel spring draws zipper head for this reason in the chinese utility model patent of patent number 202021638766.X, including pull-tab seat, pulling-on piece and horse hook, two installation ears have on the pull-tab seat, it has the draw-in groove to open on the installation ear, and it has the trompil to open on the pulling-on piece, and the pulling-on piece lower extreme has the horizontal pole, has convex jack-up portion on the horizontal pole, and jack-up portion is located the trompil, and the horizontal pole is worn to establish in the draw-in groove and relative installation ear can rotate, still opens locking hole and locating hole on the pull-tab seat, and the front end of horse hook has the decurrent locking portion of buckling, and the tail end of horse hook has the decurrent inlay card portion of buckling, and inlay card portion chucking makes the horse hook front end impress in the locking hole downwards in the locating hole, and the horse hook is located between two installation ears and the trompil passes the draw-on, when the pulling-on piece rotates jack-up portion can lift the horse hook jack-up and make locking portion. The jacking part drives the cross rod to rotate under the pressure of the hook, so that the whole pulling piece is flat and falls, and the pulling piece can be locked and cannot swing randomly.

Disclosure of Invention

Although the pull tab in patent 202021638766.X can be locked by a hook and swing involuntarily, another drawback is caused at the same time, that is, when this technical solution is applied to one of the sliders in a double-slider zipper, for example, the rear slider, the rear pull tab locked in a forward lying posture on the rear slider can block the tail of the front slider and the head of the rear slider which are intended to be folded together, which prevents an operator from directly knowing their folding condition by observing, and the operator can only turn over the rear pull tab backwards or directly perform blind operation, which seriously affects the use experience.

In view of this, there is a need for an improved slider structure, which includes a front slider including a front body having a front element passage, and a rear slider including a rear body having a rear element passage, a rear tab capable of being reversed back and forth on the rear body, and a pawl portion capable of protruding into or leaving the rear element passage in response to different reversed orientations of the rear tab; the rear pull head is characterized by further comprising a retainer, the retainer can enable the rear pull piece to keep a forward lying posture on the rear main body, the rear pull piece comprises a calibration mechanism, and the calibration mechanism can be combined to the head of the rear main body to reduce the amplitude of the left-right swing of the rear pull piece relative to the rear main body; when the rear pull-tab is held in a lying forward posture by the holder, the claw portion extends into the rear element passage, and the aligning mechanism is coupled not only to the head portion of the rear body but also to the tail portion of the front slider to provide a guide for the tail portion of the front slider to move forward and backward.

Among them, a conventional slide fastener generally includes a pair of fastener tapes having fastener elements. The fastener element channel is a fastener element moving channel arranged on the slider, a common fastener element channel is Y-shaped, and the closed or separated state of the pair of fastener tapes is switched by controlling the sliding direction of the fastener tapes in the fastener element channel.

When the rear pull tab turns forwards to a lying posture, the claw part responds to the forward turning action of the rear pull tab, extends into the rear zipper tooth channel and is clamped between two zipper teeth which are arranged in a front-back split mode, and therefore the position of the rear pull head on the chain belt is locked; when the rear pull tab is turned backward to a certain other posture, for example, an upright posture or a recumbent posture, the claw portion is separated from the rear element channel in response to the backward turning of the rear pull tab to one of the postures, so that the locking of the position of the rear slider is released, and the rear slider can slide on the fastener tape. The movement of the claw part is controlled by the turning direction of the rear pull piece, and a user can control the movement of the claw part by turning the rear pull piece.

Wherein the rear pull-tab faces the front slider when the rear pull-tab is held in a lying forward posture by the holder, and the aligning mechanism is coupled to the head portion of the rear body on the one hand and is capable of providing a guide for movement of the tail portion of the front slider, which has been coupled thereto, in the front-rear direction on the other hand.

According to the technical scheme, compared with the prior art, the invention has the beneficial technical effects that: first, since the claw portion is inserted into the rear element passage when the rear tab is held in the forward lying posture by the holder, the position of the rear slider on the fastener tape can be locked, the opening and closing range of the slide fastener is stabilized, and the rear tab is not manually operated, and generally, the rear tab is difficult to turn over at will to generate annoying noise; secondly, since the aligning mechanism is coupled not only to the head of the rear body but also to the tail of the front slider to provide a guide for the back-and-forth movement of the tail of the front slider when the rear tab is held in the forward lying posture by the holder, the relative position of the head of the rear body and the tail of the front slider in the left-and-right direction can be aligned by the aligning mechanism, reducing the offset margin therebetween. Therefore, the operation of turning the rear pulling-on piece forwards to the lying posture is completed, the position of the rear pulling-on piece on the chain belt can be locked, the guide for providing the front and back movement for the tail part of the front pulling-on piece by utilizing the calibrating mechanism on the rear pulling-on piece can be prepared in advance, the rear pulling-on piece kept in the lying forward posture does not obstruct the combination of the rear pulling-on piece and the front pulling-on piece, convenience is provided on the contrary, the rear pulling-on piece is locked on the chain belt while the guiding effect of the calibrating mechanism is utilized, and the situation that a user forgets to lock the rear pulling-on piece to open the zipper accidentally is avoided.

The structural form of the holder can be varied, two of which are preferred being provided below:

the first structure form of the retainer: the retainer comprises a clamping groove and a clamping arm which are interchangeably arranged on the rear pull piece and the rear main body and can be in matched clamping connection, and the claw part is convexly arranged on the rear pull piece. Therefore, when the rear pull tab is turned forwards to a lying posture, the clamping groove and the clamping arm are clamped together to enable the rear pull tab to keep the lying posture forwards, and meanwhile, the claw part extends into the rear zipper tooth channel along with the turning of the rear pull tab; when the rear pulling piece is turned backwards forcefully to enable the clamping arms to leave the clamping grooves, the rear pulling piece can be turned backwards and simultaneously drives the claw parts to leave the rear zipper tooth channel. The interchangeability indicates that when the clamping groove is arranged on the rear pull piece, the clamping arm is arranged on the rear main body; on the contrary, when the clamping arm is arranged on the rear pulling piece, the clamping groove is arranged on the rear main body.

The second structure form of the retainer: the rear pull piece comprises a rotating shaft part and a holding part, the calibrating mechanism is arranged on the holding part, the rotating shaft part comprises a shaft neck part and an eccentric part which is offset relative to the shaft neck part in the radial direction, and the rear pull piece is arranged on the rear main body in a manner that the rear pull piece can be turned over back and forth through the shaft neck part; the retainer is an elastic sheet which comprises a positioning part limited on the rear main body and a movable part capable of swinging up and down and stretching over the eccentric part, the claw part is formed on the movable part, and the movable part can be jacked up by the eccentric part so that the claw part is separated from the rear zipper tooth channel; when the rear pull tab turns forwards to a lying posture, the movable part loses the upward jacking action of the eccentric part to enable the claw part to extend into the rear zipper tooth channel, and meanwhile, the movable part jacks downwards to prevent the eccentric part from rotating so as to enable the rear pull tab to keep the forward lying posture. When the rotating shaft part rotates, the center of the eccentric part revolves around the rotating shaft, so that the eccentric part can jack up the movable part in a certain range in the stroke of revolution one circle, and the eccentric part can not jack up the movable part in another certain range.

The further technical scheme can also be that the eccentric part is arranged in a downward and forward mode in the radial direction by taking the rear pull tab for keeping the forward lying posture as a reference system. Thus, when the rear pull tab is turned backwards to an upward standing posture or a backward lying posture, the movable part can be jacked upwards through the eccentric part, and the claw part is separated from the rear zipper tooth channel to release the locking of the rear pull head on the zipper belt position.

Further, according to the technical scheme, when the rear pull tab turns backwards to the lying posture, the movable portion is jacked upwards by the eccentric portion to enable the claw portion to leave the rear zipper tooth channel, and meanwhile, the movable portion is jacked downwards to prevent the eccentric portion from rotating so that the rear pull tab keeps the lying posture backwards. In such a case, the resistance to the turning of the rear pull tab is increased, and if the rear pull tab is not manually operated, the rear pull tab is generally difficult to turn randomly, and the rear slider will be maintained in an unlocked state. But still can turn the rear pull-tab forwards when a certain force is applied to the rear pull-tab by human hands.

The technical scheme can also be that a groove part with an upward opening is arranged on the rear main body, and the positioning part is inserted into and limited in the groove part; the rear pull head also comprises a decorative outer cover which is covered on the groove part. Thus, the mounting operation of the elastic sheet can be simplified, and the appearance effect of the rear pull head can be optimized by utilizing the decorative outer cover.

The structural form of the calibration mechanism can be various, and two structural forms are provided below, wherein the two structural forms are preferable:

the first structural form of the calibration mechanism is as follows: the calibration mechanism is provided with a door frame-shaped cross section structure and comprises a pair of outward flanges which are arranged on the left side and the right side respectively and a connecting plate connected between the pair of outward flanges, and the pair of outward flanges can clamp the tail part of the front pull head and the head part of the rear pull head.

The technical scheme is that the front puller further comprises a front pull piece, and a pull nose connected with the front pull piece is arranged on the front body; and a gap for avoiding the pull nose is arranged on the connecting plate.

The second structural form of the calibration mechanism is as follows: the tail part of the front pull head and the head part of the rear pull head are respectively provided with a concave pit, and the calibration mechanism is a bulge which can be inserted into the concave pit.

The third structural form of the calibration mechanism is as follows: the calibration mechanism is a concave pit, and the tail part of the front pull head and the head part of the rear pull head are respectively provided with a bulge which can be inserted into the concave pit.

In addition, the invention also provides a zipper, which comprises a pair of zipper belts and the pair of sliders capable of being arranged in front and back, wherein the pair of sliders can slide on the zipper belts.
