The invention is further described with reference to the following drawings and detailed description.

The first embodiment is as follows:

the schematic view of the slide fastener of this embodiment is shown in FIGS. 2-4. The slide fastener a includes a pair of fastener stringers 1, a first slider 2, a second slider 3, and a first unlocking mechanism 4. When the first slider 2 and the second slider 3 are pulled to the same position, the first slider and the second slider are connected through a buckle, and the zipper A is locked; when the first slider 2 and the second slider 3 are moved to the first unlocking mechanism 4, the first unlocking mechanism 4 moves the second locking element 31 in the unlocking direction by pushing the second transmission member 314 of the second slider 3, and then moves the second slider 3 to the end far from the first unlocking mechanism 4, so that the two sliders are unlocked.

The first slider 2 comprises a first locking element 21 and a first slider body 22, and the second slider 3 comprises a second locking element 31 and a second slider body 32, wherein the first slider body 22 and the second slider body 32 have the same shape, and the first slider body 22 and the second slider body 32 have the function of opening and closing a zipper as in a common slider. The first and

second latch elements

21 and 31 are respectively provided on the bottom portions of the first and

second slider bodies

22 and 32 on the side close to the introduction port, which is the slider side into which the fastener chain 1 enters first when the slider is inserted into the fastener chain 1, as shown in fig. 2. Alternatively, the first and

second latch elements

21 and 31 may also be provided at the top or end of the first and

second slider bodies

22 and 32 at the same time, as shown in fig. 3-4, the first and

second latch elements

21 and 31 may be snap-connected, so that the two sliders can move together when connected to each other.

In this embodiment, the first locking element 21 and the second locking element 31 can be respectively fixed to the bottom of the first slider body 22 and the bottom of the second slider body 32 by means of pasting, snapping and the like, and when the first locking element 21 or the second locking element 31 is damaged, only the first locking element 21 or the second locking element 31 can be replaced, so that the first slider 2 or the second slider 3 can be replaced, the cost is saved, and the waste is avoided. Preferably, the first locking element 21 and the second locking element 31 can also be arranged at the bottom of the first slider body 22 and the bottom of the second slider body 32 respectively in an integrated manner, so that a stable connection can be realized, and the situation that the connection between the first locking element 21 and the first slider 2 is loosened or the connection between the second locking element 31 and the second slider 3 is loosened to influence the locking anti-theft effect of the zipper a can be avoided.

The end of the first blocking element 21 is formed with a profile 211 suitable for snapping. In this embodiment, the shape surface 211 is a notch 2111, the opening position of which is located at the end of the first latch element 21 and is opposite to the second latch element 31, and the notch 2111 is arranged in a step shape to realize the snap connection of the first slider 2 and the second slider 3.

The second latching member 31 includes a second body portion 311, a collet 312, a second elastic member 313, and a second transmission member 314. One end of the chuck 312 is provided with an elastic hook 3121, the structure of which is matched with the slot 2111 of the first locking element 21, and the chuck can be fastened in the slot 2111 of the first locking element 21 and separated from the slot 2111, so as to realize separation. The second main body part 311 is formed with a groove for accommodating the chuck 312, one end of the chuck 312 with the elastic hook 3121 is disposed outside the second main body part 311, the other end is fixedly connected with the second elastic member 313 and disposed in the groove, and the second elastic member 313 and the hook 3121 are opposite in direction, and are used for resetting the chuck 312 to realize a snap connection. The second transmission member 314 is disposed on the chuck 312 outside the second body portion 311, fixedly connected with the chuck 312, and extends to the lower side of the second slider 3, for driving the chuck 312 to move. The second transmission member 314 may be a push rod extending outward, and when the push rod is subjected to a force in a direction away from the first unlocking mechanism 4, the push rod may drive the chuck 312 to move in a direction of compressing the second elastic member 313, and when the force disappears, the second elastic member 313 drives the chuck 312 to reset. It should be understood that the second elastic member 313 according to this embodiment may be a member having elastic deformation and disposed separately from the chuck 312, such as a coil spring, a torsion bar spring, and a rubber spring, and capable of driving the chuck 312 to move. The second elastic member 313 may also be an elastic sheet made of an elastic material, and the elastic sheet may be in various shapes and is separately disposed from or integrally formed with the chuck 312, so that the chuck 312 may compress the second elastic member 313 to move when an external force is applied or the second elastic member 313 drives the chuck 312 to return to an initial position when the external force disappears. Preferably, the push rod and the chuck 312 may be configured as an integrated structure, so that the chuck 312 can be better driven to move when an external force is applied. Optionally, when the clip 312 is fixed in the second main body portion 311, the hook 3121 may be set to any other direction, and the corresponding slot 2111 should be set to a direction matching with the hook 3121, so as to realize the snap connection between the hook 3121 and the slot 2111.

Alternatively, in this embodiment, the second elastic member 313 is not necessarily provided, and by providing the collet 312 as a member having elastic properties, the collet 312 can slide into the notch 2111 or move to unlock according to its elastic deformation.

The first unlocking mechanism 4 includes a first top plate 41 fixed to the fastener stringer 1 on the side close to the first slider 2. The first top plate 41 is disposed on one side of the bottom of the slider, i.e. below the slider, and is used for pushing the push rod of the second transmission member 314 to drive the chuck 312 to move in a direction of compressing the second elastic member 313 so as to unlock the slider. The first top plate 41 may be configured as a square sheet or a trapezoid sheet, so long as when two sliders are pulled to the first unlocking mechanism 4, an end of the first top plate 41 close to the slider side may contact with the push rod to push the push rod.

In this embodiment, the zipper a further comprises a flap 6 (not shown in the figures). The baffle 6 is a rigid plate material, and can be made of metal, plastic or wood materials. The baffle 6 is disposed above the first locking member 21 or the second locking member 31, and the longitudinal direction thereof is parallel to the extending direction of the fastener chain 1. When the first locking element 21 and the second locking element 31 are connected together in a buckling mode, the baffle 6 shields the first locking element 21 and the second locking element 31 from the upper side of the locking elements, a pickpocket can be prevented from opening the zipper from the outer side of the zipper through tools such as a fine needle, and the anti-theft effect is better.

In another alternative embodiment, the two rows of elements of the fastener chain 1 are engaged with each other by the slider, and the included angle formed between the two rows of elements after engagement is not the usual 180 degrees, but the planes of the two rows of elements are crossed with each other to form a predetermined angle which is properly smaller than 180 degrees and protrudes outward, so that the two rows of elements are inclined as a whole; when the slide fastener a in the engaged state with a predetermined angle is broken using the sharp object, the sharp object slips due to the inclination of the fastener chain 1, preventing the slide fastener from being broken open by an external force.

Thus, the first unlocking mechanism 4 is fixedly provided at one end of the fastener chain 1, the first slider 2 and the second slider 3 are provided in the middle of the fastener chain 1, and the first slider 2 is provided on the side close to the first unlocking mechanism 4. When the zipper A is in a closed state, the first slider 2 and the second slider 3 are close together, the clamping head 312 of the second locking element 31 is connected with the clamping groove 2111 of the first locking element 21 in a clamping mode, at the moment, the first slider 2 and the second slider 3 are pulled randomly, the two sliders are connected with each other and move together, and the zipper A is still in the closed state; when the two sliders are pulled to the extent that the push rod is in contact with the first top plate 41 of the first unlocking mechanism 4 and the sliders cannot move continuously, the push rod drives the chuck 312 to move towards the direction of compressing the second elastic component 313 under the action of the first top plate 41, then the second slider 3 on the side far away from the first unlocking mechanism 4 is pulled to move towards the end far away from the first unlocking mechanism 4, the first slider 2 is separated from the second slider 3, and the zipper A is opened. When the zipper is closed, only the sliders on either side are pulled to move towards the other slider, so that the first slider 2 and the second slider 3 are tightly close together again, and the clamping head 312 of the second locking element 31 and the clamping groove 2111 of the first locking element 21 are connected together again in a clamping manner.

Example two:

fig. 5 to 6 are bottom views of the slide fastener of the present embodiment. In the present embodiment, the slide fastener a includes a pair of fastener stringers 1, a first slider 2, a second slider 3, and a first unlocking mechanism 4. When the first slider 2 and the second slider 3 are pulled to the same position, the first slider and the second slider are connected through a buckle, and the zipper A is locked; when the first slider 2 and the second slider 3 are moved to the first unlocking mechanism 4, the first unlocking mechanism 4 moves the second locking element 31 in the unlocking direction by pushing the second transmission member 314 of the second slider 3, and then moves the second slider 3 to the end far from the first unlocking mechanism 4, so that the two sliders are unlocked.

The first unlocking mechanism 4 includes a first slide groove 42 that forms a predetermined angle with the extending direction of the fastener chain 1. The first sliding slot 42 is configured to be matched with the push rod of the second transmission component 314, so that when the push rod moves along the first sliding slot 42, the push rod drives the chuck 312 to move and unlock in a direction of compressing the second elastic component 313, as shown in fig. 6. Alternatively, the push rod may be arranged in a downward direction perpendicular to the clamp head 312 or in other directions, the corresponding first sliding groove 42 may be arranged in a curved groove in the same direction as the push rod or in a linear groove forming a predetermined angle with the extending direction of the fastener chain 1, the opening of the first sliding groove 42 is in a horizontal line with the push rod, and when the push rod advances along the first sliding groove 42, the clamp head 312 is driven to move in a direction of compressing the second elastic member 313 to achieve unlocking. It should be understood that the second elastic member 313 according to the embodiment may be a coil spring, a torsion bar spring, a rubber spring, or the like having elastic deformation to move the chuck 312. The second elastic member 313 may also be an elastic sheet made of an elastic material, and the elastic sheet may be in various shapes and is separately disposed from or integrally formed with the chuck 312, so that the chuck 312 may compress the second elastic member 313 to move when an external force is applied or the second elastic member 313 drives the chuck 312 to return to an initial position when the external force disappears. Alternatively, in this embodiment, the second elastic member 313 is not necessarily provided, and by providing the collet 312 as a member having elastic properties, the collet 312 can slide into the notch 2111 or move to unlock according to its elastic deformation.

The fastener stringer 1, the first slider 2, and the second slider 3 of the present embodiment are arranged in a manner similar to the structure of the first embodiment, and will not be described again.

In the present embodiment, a first unlocking mechanism 4 is fixedly provided at one end of the fastener chain 1, a first slider 2 and a second slider 3 are provided in the middle of the fastener chain 1, and the first slider 2 is provided on the side close to the first unlocking mechanism 4. When the zipper A is in a closed state, the first slider 2 and the second slider 3 are close together, the clamping head 312 of the second locking element 31 is connected with the clamping groove 2111 of the first locking element 21 in a clamping mode, at the moment, the first slider 2 and the second slider 3 are pulled randomly, the two sliders are connected with each other and move together, and the zipper A is still in the closed state; when the two sliders are pulled to move in the first sliding groove 42 of the first unlocking mechanism 4 and the sliders cannot move continuously, the push rod drives the chuck 312 to move towards the direction of compressing the second elastic component 313 under the action force of the first sliding groove 42, then the second slider 3 on the side far away from the first unlocking mechanism 4 is pulled to move towards the end far away from the first unlocking mechanism 4, the first slider 2 is separated from the second slider 3, and the zipper A is opened. When the zipper is closed, only the sliders on either side are pulled to move towards the other slider, so that the first slider 2 and the second slider 3 are tightly close together again, and the clamping head 312 of the second locking element 31 and the clamping groove 2111 of the first locking element 21 are connected together again in a clamping manner.

Example three:

the schematic view of the slide fastener of the present embodiment is shown in fig. 7 to 12. The slide fastener a includes a pair of fastener stringers 1, a first slider 2, a second slider 3, and a first unlocking mechanism 4. When the first slider 2 and the second slider 3 are pulled to the same position, the first slider and the second slider are connected through a buckle, and the zipper A is locked; when the first slider 2 and the second slider 3 are moved to the first unlocking mechanism 4, the first unlocking mechanism 4 rotates the first locking element 21 in the unlocking direction by pushing the first transmission member 214 of the first slider 2, and then moves the second slider 3 to the end far from the first unlocking mechanism 4, so that the two sliders are unlocked.

second latch elements

21, 31 are provided at the ends of the first and

second slider bodies

22, 32, respectively, as shown in fig. 7. Alternatively, the first and

second latch elements

21 and 31 can also be disposed at the top or bottom of the first and

second slider bodies

22 and 32 on the side close to the introduction port at the same time, so that the first and

second latch elements

21 and 31 realize a snap connection, and thus the two sliders can move together when connected to each other.

In the present embodiment, the first latch member 21 is rotatably attached to the end of the first slider body 22, and the rotation axis of the first latch member 21 is parallel to the extending direction of the fastener chain 1, as shown in fig. 7 and 9. Alternatively, the first latch member 21 may be arranged such that its pivot axis is parallel to the width direction of the slider, as shown in fig. 10. It is also possible to arrange the first blocking element 21 with its pivoting axis parallel to the thickness direction of the slider, as shown in fig. 12. Alternatively, the first latch member 21 of different hinge directions may also be rotatably attached to the top or bottom of the first slider body 22. The second latch element 31 corresponding thereto is attached to the top or bottom of the second slider body 32.

The second locking element 31 is fixed at the end of the second slider body 32 by sticking, buckling and the like, when the first locking element 21 or the second locking element 31 is damaged, only the first locking element 21 or the second locking element 31 can be replaced, so that the first slider 2 or the second slider 3 can be replaced, the cost is saved, and the waste is avoided. Preferably, the second locking element 31 can also be arranged at the end of the second slider body 32 by means of integral molding, so that a stable connection can be realized, and the locking anti-theft effect of the slide fastener a is prevented from being affected by the looseness of the connection between the second locking element 31 and the second slider 3.

The end of the second locking element 31 is fixedly provided with a catch 312, which is provided with a catch in a predetermined direction. The first latching member 21 includes a first main body portion 212, a first elastic member 213 (not shown in the drawings), and a first transmission member 214. The first body portion 212 is formed with a profile 211 adapted for snap-fit. In this embodiment, the shape surface 211 is a slot 2111, and the slot 2111 is configured to have a step-like structure, so that the chuck 312 can be locked in the slot 2111. The card slot 2111 includes a first opening and a second opening connected to an edge of the first opening. Wherein the second opening is smaller than the first opening, as shown in fig. 9. The first elastic member 213 is fixedly connected to the first body portion 212 and the first slider body 22 along the circumferential direction of the first body portion 212, respectively, so that the first body portion 212 is at a predetermined position, which is a predetermined angle between the second opening of the notch 2111 and the hook.

In this embodiment, the edge position of the opening may be set to have a certain curvature or slope, the end of the hook is set to have a corresponding curvature or slope, when the first slider 2 and the second slider 3 are abutted together, the chuck 312 contacts with the arc-shaped edge of the opening to push the first main body part 212 to rotate along the rotation axis, so that the second opening of the notch 2111 rotates from a predetermined position to coincide with the predetermined direction of the hook, so that the hook is inserted into the notch 2111 through the second opening of the notch 2111, and at this time, the first elastic member 213 is stretched or compressed; after the hook enters the slot 2111, the first main body 212 is no longer stressed, so that the first main body 212 is reset and rotated to a predetermined position under the action of the first elastic component 213, and at this time, the hook and the slot 2111 realize a snap connection, as shown in fig. 9, so that the two sliders can be connected and moved together. It should be understood that the first elastic member 213 according to the embodiment may be a coil spring, a torsion bar spring, a rubber spring, or the like having elastic deformation to move the chuck 312.

The first transmission component 214 is fixedly connected with the first body part 212 and extends to the lower part of the first slider 2, so as to drive the first body part 212 to rotate for unlocking. The first transmission component 214 can be a push rod extending outward, when the push rod receives an external force perpendicular to the rotation axis of the first main body 212, the push rod can drive the first main body 212 to rotate, the rotation direction is as an arrow direction (unlocking direction) shown in fig. 9, so that the second opening of the locking groove 2111 rotates to the predetermined direction of the hook, the second slider 3 moves to one side far away from the first unlocking mechanism 4, the hook is separated from the locking groove 2111, and the two sliders are unlocked. When the force disappears, the first elastic member 213 drives the first main body 212 to reset. Preferably, the push rod and the first main body 212 may be integrally formed, so that the first main body 212 can be better driven to move when an external force is applied. When the first locking member 21 is disposed such that the rotation axis thereof is parallel to the extending direction of the fastener chain 1, the first transmission part 214 may be disposed on the curved surface of the first body part 212, and the first elastic part 213 may be disposed on the curved surface of the first body part 212 or the end surface on the side close to the slider.

When the first unlocking mechanism 4 pushes the first transmission member 214, the first transmission member 214 drives the first main body portion 212 to rotate, and when the slider is disengaged from the first unlocking mechanism 4, the first main body portion 212 is reset. When the first latching member 21 is disposed such that the rotation axis thereof is parallel to the width direction of the slider, the first transmission part 214 may be disposed on the curved surface or both end surfaces of the first body part 212, and the first elastic part 213 may be disposed on the curved surface or both end surfaces of the first body part 212. When the first unlocking mechanism 4 pushes the first transmission member 214, the first transmission member 214 drives the first main body portion 212 to rotate, and when the slider is disengaged from the first unlocking mechanism 4, the first main body portion 212 is reset. When the first latch member 21 is disposed such that the rotation axis thereof is parallel to the thickness direction of the slider, the first transmission member 214 may be disposed on the arc-shaped curved surface of the first body portion 212 or the lower end surface thereof, and the first elastic member 213 may be disposed on the arc-shaped curved surface of the first body portion 212. When the first unlocking mechanism 4 pushes the first transmission member 214, the first transmission member 214 drives the first main body portion 212 to rotate, and when the slider is disengaged from the first unlocking mechanism 4, the first main body portion 212 is reset. The first unlocking mechanism 4 includes a first top plate 41 fixed to the fastener stringer 1 on the side close to the first slider 2. The first top plate 41 is disposed on one side of the bottom of the slider, and is used for pushing the push rod of the first transmission component 214 to drive the first main body 212 to rotate so as to unlock.

Thus, the first unlocking mechanism 4 is fixedly provided at one end of the fastener chain 1, the first slider 2 and the second slider 3 are provided in the middle of the fastener chain 1, and the first slider 2 is provided on the side close to the first unlocking mechanism 4. When the zipper A is in a closed state, the first slider 2 and the second slider 3 are close together, the clamping head 312 of the second locking element 31 is connected with the clamping groove 2111 of the first locking element 21 in a clamping mode, at the moment, the first slider 2 and the second slider 3 are pulled randomly, the two sliders are connected with each other and move together, and the zipper A is still in the closed state; when the two sliders are pulled to the extent that the push rod is in contact with the first top plate 41 of the first unlocking mechanism 4 and the sliders cannot move continuously, the push rod drives the first main body part 212 to rotate towards the unlocking direction under the action force of the first top plate 41, then the second slider 3 on the side far away from the first unlocking mechanism 4 is pulled to move towards the end far away from the first unlocking mechanism 4, the first slider 2 is separated from the second slider 3, and the zipper A is opened. When the zipper is closed, only the sliders on either side are pulled to move towards the other slider, so that the first slider 2 and the second slider 3 are tightly close together again, and the clamping head 312 of the second locking element 31 and the clamping groove 2111 of the first locking element 21 are connected together again in a clamping manner.

Example four:

the schematic view of the slide fastener of the present embodiment is shown in fig. 13 to 16. The slide fastener a includes a pair of stringers 1, a first slider 2, a second slider 3, a first unlocking mechanism 4, and a second unlocking mechanism 5. The fastener chain 1 is provided on a chain belt and can be engaged with each other. The first slider 2 and the second slider 3 are disposed on the fastener chain 1 in opposition for sliding on the fastener chain 1 to open or close the slide fastener a. The opposite arrangement means that the first slider 2 and the second slider 3 are arranged in opposite directions, i.e. oppositely arranged or face to face. The first unlocking mechanism 4 and the second unlocking mechanism 5 are respectively arranged at two ends of the zipper 1 and are used for separating the first slider 2 and the second slider 3 which are mutually closed to realize unlocking. When the first slider 2 and the second slider 3 are pulled to the same position, the connection is carried out through the buckle, and the zipper A is locked; when the first slider 2 and the second slider 3 are moved to the first unlocking mechanism 4 or the second unlocking mechanism 5, the first unlocking mechanism 4 or the second unlocking mechanism 5 drives the chuck of the second slider 3 to move towards a preset direction, the second slider 3 or the first slider 2 is moved towards one end far away from the unlocking mechanism, and the two sliders are unlocked.

The first slider 2 comprises a first locking element 21 and a first slider body 22, and the second slider 3 comprises a second locking element 31 and a second slider body 32, wherein the first slider body 22 and the second slider body 32 have the same shape, and pull

handles

221, 321 are connected to the top surfaces of the first slider body 22 and the second slider body 32, and can be configured as pull rods or pull rings for pulling the sliders to move. The first and

second latch elements

21 and 31 may be provided at the introduction port side of the first and

second slider bodies

22 and 32 at the same time. The introduction port is a side of the slider where the fastener chain 1 enters first when the slider penetrates the fastener chain 1. Alternatively, the first and

second latch elements

21 and 31 may be provided at the top, end, or bottom of the introduction port side of the first and

second slider bodies

22 and 32 at the same time. When the first slider 2 and the second slider 3 are pulled to one place in opposite directions, the first latching element 21 and the second latching element 31 come into contact to achieve a snap connection, so that the two sliders can move together when connected to each other, as shown in fig. 13 and 14.

In this embodiment, the first and

second latch elements

21 and 31 may be fixed to the top of the first and

second slider bodies

22 and 32, respectively, by gluing, bolting, etc. When the first locking element 21 or the second locking element 31 is damaged, only the first locking element 21 or the second locking element 31 can be replaced, so that the first slider 2 or the second slider 3 can be replaced, the cost is saved, and the waste is avoided. Preferably, the first locking element 21 and the second locking element 31 can also be arranged on the top of the first slider body 22 and the top of the second slider body 32 respectively in an integrated manner, so that a stable connection can be realized, and the situation that the connection between the first locking element 21 and the first slider 2 is loosened or the connection between the second locking element 31 and the second slider 3 is loosened to influence the locking anti-theft effect of the zipper a can be avoided.

The end of the first blocking element 21 is formed with a profile 211 suitable for snapping. In this embodiment, the shape surface 211 is configured as a locking groove 2111, the opening position of which is located at the end of the first latch element 21 and is opposite to the second latch element 31, and the locking groove 2111 is configured as a step shape or a convex-concave shape to realize the snap connection of the first slider 2 and the second slider 3.

The second latching member 31 includes a second body portion 311, a collet 312, a second elastic member 313, and a second transmission member 314. One end of the chuck 312 is provided with a hook 3121, the structure of which is matched with the slot 2111 of the first locking element 21, and the chuck can be fastened in the slot 2111 of the first locking element 21 and separated from the slot 2111, so as to realize separation. The hooks 3121 can be configured as rigid or elastic hooks. The second main body 311 is formed with a recess for accommodating the clip 312, one end of the clip 312 with the hook 3121 is disposed outside the second main body 311, and the other end is fixedly connected to one end of the second elastic member 313. The second elastic component 313 is arranged in the groove, and the bottom of the second elastic component is fixedly connected with the bottom surface of the groove. The second elastic component 313 is opposite to the hook 3121 in the setting direction, and is used for resetting the chuck 312 to realize the snap connection. The second transmission member 314 is disposed on the chuck 312 outside the second body portion 311, fixedly connected with the chuck 312, and extends to the lower side of the second slider 3, for driving the chuck 312 to move.

The second transmission member 314 may be provided as a push rod 3141 extending outward, and a protrusion 3142 is provided at a lower end of the push rod 3141. The cross-sectional area of the protrusion 3142 is larger than that of the push rod 3141, and the protrusion 3142 extends along the end surface of the push rod 3141 to two sides to form a trapezoid structure with the push rod 3141. When the second transmission member 314 receives a force applied in a predetermined direction, the second transmission member 314 can drive the chuck 312 to move in a direction of compressing the second elastic member 313. In this embodiment, the predetermined direction is a direction downward along the length of the push rod 3141, i.e., the same direction downward as the height direction of the slider. When the force disappears, the second elastic member 313 drives the chuck 312 and the second transmission member 314 to reset by means of its own elastic force. It should be understood that the second elastic member 313 according to the embodiment may be a coil spring, a torsion bar spring, a rubber spring, or the like having elastic deformation to move the chuck 312. The second elastic member 313 may also be an elastic sheet made of an elastic material, and the elastic sheet may be in various shapes and is separately disposed from or integrally formed with the chuck 312, so that the chuck 312 may compress the second elastic member 313 to move when an external force is applied or the second elastic member 313 drives the chuck 312 to return to an initial position when the external force disappears. Preferably, the second transmission member 314 and the chuck 312 may be integrally formed, so that the chuck 312 can be moved when an external force is applied. Optionally, when the clip 312 is fixed in the second main body portion 311, the hook 3121 may be set to any other direction, and the corresponding slot 2111 should be set to a direction matching with the hook 3121, so as to realize the snap connection between the hook 3121 and the slot 2111.

Alternatively, in this embodiment, the second elastic member 313 is not necessarily provided, and by providing the chuck 312 as a member having elastic properties, the chuck 312 can slide into the notch 2111 to be snapped or moved to be unlocked according to its elastic deformation.

The first unlocking mechanism 4 and the second unlocking mechanism 5 are respectively arranged at two ends of the zipper 1 in opposite directions and used for unlocking two sliders closed together so as to open the zipper A. In the present embodiment, the first unlocking mechanism 4 and the second unlocking mechanism 5 have the same structure, and the first inclined surface 43 and the second inclined surface 53 are respectively arranged at the front end portions of the first unlocking mechanism 4 and the second unlocking mechanism 5, i.e., the side close to the slider, and the inclination angle can be set according to actual needs. The front ends of the first unlocking mechanism 4 and the second unlocking mechanism 5 are respectively provided with a first sliding chute 42 and a second sliding chute 52 which are arranged along the length direction or the chain extending direction of the unlocking mechanism and penetrate through the unlocking mechanism in height. The openings of the first sliding groove 42 and the second sliding groove 52 are respectively arranged at the first inclined surface 43 and the second inclined surface 53 and are communicated with the outside. The dimensions of the first sliding groove 42 and the second sliding groove 52 in the width direction of the unlocking mechanism, i.e. the width of the first sliding groove 42 and the width of the second sliding groove 52, are both greater than the width dimension of the push rod 3141 and less than the width dimension of the projection 3142. Further, after the unlocking mechanism is mounted on the fastener chain 1, in the left view direction of the slide fastener a, the protrusion 3142 and a part of the push rod 3141 connected to the protrusion partially overlap with the unlocking mechanism, so that the push rod 3141 can move along the opening of the first sliding groove 42 or the second sliding groove 52 into the first sliding groove 42 and the second sliding groove 52, and the protrusion 3142 moves downward along the first inclined surface 43 and the second inclined surface 53, and the protrusion 3142 and the push rod 3141 drive the chuck 312 to move (downward) in the direction of compressing the second elastic member 313 for unlocking, as shown in fig. 14. Alternatively, the surfaces of the protrusion 3142 contacting the first inclined surfaces 43 and the second inclined surfaces 53 of the first unlocking mechanism 4 and the second unlocking mechanism 5 may be provided as planes having the same inclination angle as the first inclined surfaces 43 and the second inclined surfaces 53, that is, the cross-sectional view of the protrusion 3142 may be provided as a trapezoid. In other implementations, the first and second

inclined surfaces

43 and 53 of the first and second unlocking

mechanisms

4 and 5 may be set to different angles as long as unlocking of the two sliders by either one of the unlocking mechanisms can be achieved.

Alternatively, the push rod 3141 may be disposed in a vertically downward direction or an inclined direction at another angle with respect to the chuck 312, and the corresponding first and second sliding

grooves

42 and 52 may be disposed as inclined sliding grooves in the same direction as the push rod 3141. That is, the openings of the first sliding groove 42 and the second sliding groove 52 are inclined openings, and the inclined openings and the push rod 3141 are on the same inclined plane. When the push rod 3141 advances along the first sliding groove 42 and the second sliding groove 52, the protrusion 3142 moves along the first inclined surface 43 and the second inclined surface 53 of the unlocking mechanism, and the push rod 3141 drives the chuck 312 to move in a direction of compressing the second elastic member 313 to realize unlocking. It should be understood that the second elastic member 313 according to the embodiment may be a coil spring, a torsion bar spring, a rubber spring, or the like having elastic deformation to move the chuck 312.

Thus, the first unlocking mechanism 4 and the second unlocking mechanism 5 are fixedly provided at both ends of the fastener chain 1 so as to face each other, and the first slider 2 and the second slider 3 are provided at the middle of the fastener chain 1 so as to face each other. When the zipper A is in a closed state, the first slider 2 and the second slider 3 are close together, the clamping head 312 of the second locking element 31 is connected with the clamping groove 2111 of the first locking element 21 in a clamping mode, at the moment, the first slider 2 and the second slider 3 are pulled randomly, the two sliders are connected with each other and move together, and the zipper A is still in the closed state; when two sliders are pulled to the unlocking mechanism at any end, the second transmission component 314 moves along the sliding groove of the unlocking mechanism, under the action force and the reaction force generated by the convex block 3142 and the unlocking mechanism, the convex block 3142 and the push rod 3141 drive the slider 312 to move towards the direction of compressing the second elastic component 313, then the slider far away from one side of the unlocking mechanism is pulled to move towards the end far away from the unlocking mechanism, the first slider 2 is separated from the second slider 3, and the zipper A is opened. When the zipper is closed, only the sliders on either side are pulled to move towards the other slider, so that the first slider 2 and the second slider 3 are tightly close together again, and the clamping head 312 of the second locking element 31 and the clamping groove 2111 of the first locking element 21 are connected together again in a clamping manner. The zipper A of the embodiment has simple structure and easy manufacture, and people unfamiliar with the zipper structure can not know how to open the zipper A, so the anti-theft effect is good. The zipper A in the embodiment can be applied to articles such as bags, clothes, tents and the like, and has an anti-theft effect while realizing the object sealing.

In addition, the slide fastener a in this embodiment may be provided with only one unlocking mechanism, and may be provided on any one side of the fastener chain 1. When the two closed sliders need to be unlocked, unlocking can be performed only by pulling the two sliders to one side where the unlocking mechanism is located.

Example five:

the schematic view of the slide fastener of the present embodiment is shown in fig. 17 to 19. The slide fastener a includes a pair of stringers 1, a first slider 2, a second slider 3, a first unlocking mechanism 4, and a second unlocking mechanism 5. The fastener chain 1 is provided on a chain belt and can be engaged with each other. The first slider 2 and the second slider 3 are disposed on the fastener chain 1 in opposition for sliding on the fastener chain 1 to open or close the slide fastener a. The opposite arrangement means that the first slider 2 and the second slider 3 are arranged in opposite directions, i.e. oppositely arranged or face to face. The first unlocking mechanism 4 and the second unlocking mechanism 5 are respectively arranged at two ends of the zipper 1 and are used for separating the first slider 2 and the second slider 3 which are mutually closed to realize unlocking. When the first slider 2 and the second slider 3 are pulled to the same position, the connection is carried out through the buckle, and the zipper A is locked; when the first slider 2 and the second slider 3 are moved to the first unlocking mechanism 4 or the second unlocking mechanism 5, the first unlocking mechanism 4 or the second unlocking mechanism 5 pushes the first locking element 21 of the first slider 2 to rotate towards a preset direction, the second slider 3 or the first slider 2 is moved towards one end far away from the unlocking mechanism, and the two sliders are unlocked.

22 and 32 at the same time. When the first slider 2 and the second slider 3 are pulled to one place in opposite directions, the first latching element 21 and the second latching element 31 are in contact to realize a snap connection, so that the two sliders can move together when connected to each other, as shown in fig. 17.

In this embodiment, the first latch element 21 is rotatably attached to the end of the first slider body 22, and the rotation axis of the first latch element 21 is parallel to the thickness direction of the slider, i.e., the first latch element 21 rotates in the horizontal direction of the slide fastener a, as shown in fig. 17. Alternatively, the first latch element 21 may be arranged such that its pivot axis is parallel to the width direction of the slider or parallel to the extending direction of the fastener chain. Alternatively, the first latch member 21 of different hinge directions may also be rotatably attached to the top or bottom of the first slider body 22. The second latch element 31 corresponding thereto is attached to the top or bottom of the second slider body 32.

The second latch element 31 is fixed to an end of the second slider body 32 by means of gluing or the like. When the first locking element 21 or the second locking element 31 is damaged, only the first locking element 21 or the second locking element 31 can be replaced, so that the first slider 2 or the second slider 3 can be replaced, the cost is saved, and the waste is avoided. Preferably, the second locking element 31 can also be arranged at the end of the second slider body 32 by means of integral molding, so that a stable connection can be realized, and the locking anti-theft effect of the slide fastener a is prevented from being affected by the looseness of the connection between the second locking element 31 and the second slider 3.

The second blocking element 31 is provided as a catch 312, which is provided with a catch 3121 in a predetermined direction. The first latching element 21 includes a first main body portion 212, a first elastic member 213, and a first transmission member 214. In the present embodiment, the first transmission component 214 includes a first transmission assembly 2141 and a second transmission assembly 2142. The first body portion 212 is formed with a profile 211 adapted for snap-fit. In this embodiment, the shape surface 211 is configured as a slot 2111, and the slot 2111 is configured to have a step-like structure, so that the chuck 312 can be snapped into the slot 2111. The card slot 2111 includes a first opening and a second opening connected to an edge of the first opening. Wherein the second opening is smaller than the first opening, as shown in fig. 19. The first elastic member 213 is fixedly connected to the first body portion 212 and the first slider body 22 in the circumferential direction of the first body portion 212, respectively, so that the first body portion 212 is at a predetermined position where the second opening of the notch 2111 and the hook 3121 form a predetermined angle. In this embodiment, the edge position of the opening may be set to have a certain curvature or slope, the end of the hook is set to have a corresponding curvature or slope, when the first slider 2 and the second slider 3 are abutted together, the contact of the collet 312 with the curved edge of the opening pushes the first main body part 212 to rotate along the rotation axis, so that the second opening of the card slot 2111 rotates from a predetermined position to coincide with the predetermined direction of the hook 3121, so that the hook 3121 is inserted into the card slot 2111 through the second opening of the card slot 2111, at which time, the first elastic member 213 is stretched or compressed; after the hook 3121 enters the slot 2111, the first main body 212 is no longer stressed, so the first main body 212 is reset and rotated to a predetermined position under the action of the first elastic component 213, and at this time, the hook 3121 and the slot 2111 realize a snap connection, as shown in fig. 17, so that the two sliders can be connected and moved together. It should be understood that the first elastic member 213 according to the embodiment may be a coil spring, a torsion bar spring, a rubber spring, or the like having elastic deformation to move the chuck 312.

The first transmission assembly 2141 and the second transmission assembly 2142 are sequentially and fixedly connected with the first main body portion 212 along the width direction of the slider and extend to the lower side of the first slider 2, so as to drive the first main body portion 212 to rotate and unlock. That is, the first transmission assembly 2141 and the second transmission assembly 2142 are disposed on two sides of the notch 2111 of the first main body portion 212, as shown in fig. 18 and 19. The first transmission assembly 2141 and the second transmission assembly 2142 may be configured as a push rod extending outward, and when the push rod is subjected to an external force perpendicular to the rotation axis of the first body portion 212, the first body portion 212 may be driven to rotate so that the second opening of the locking groove 2111 rotates to the predetermined direction of the hook 3121, the first slider 2 or the second slider 3 is moved to a side away from the unlocking mechanism, the hook 3121 is separated from the locking groove 2111, and the two sliders realize unlocking. When the force disappears, the first elastic member 213 drives the first main body 212 to reset. Preferably, the push rod and the first main body 212 may be integrally formed, so that the first main body 212 can be better driven to move when an external force is applied. Alternatively, the first transmission member 214 may be provided as a push rod having a predetermined length, as shown in fig. 20. When the two sliders are pulled to the unlocking mechanisms on either side, the first unlocking mechanism 4 and the second unlocking mechanism 5 can be unlocked by pushing the first transmission member 214.

The first unlocking mechanism 4 and the second unlocking mechanism 5 are respectively arranged at two ends of the zipper 1 in opposite directions and used for unlocking two sliders closed together so as to open the zipper A. The first unlocking mechanism 4 and the second unlocking mechanism 5 respectively include a first top plate 41 and a second top plate 51, which are respectively disposed below the slider, and the first top plate 41 and the second top plate 51 are disposed along the width direction of the slider and are respectively used for pushing the first transmission assembly 2141 and the second transmission assembly 2142 to drive the first main body portion 212 to rotate and unlock.

Alternatively, the first and

second transmission assemblies

2141 and 2142 may be arranged in a vertically downward direction or other angled oblique direction with respect to the collet 312, and the width and height of the corresponding first and second

top sheets

41 and 51 are arranged in accordance with the oblique position of the first and

second transmission assemblies

2141 and 2142. While the cross-sectional shapes of the first and second

top sheets

41 and 51 may be arranged accordingly. It should be understood that the first elastic member 213 according to the embodiment can be a coil spring, a torsion bar spring, a rubber spring, etc. having elastic deformation to drive the first main body 212 to rotate.

Thus, the first unlocking mechanism 4 and the second unlocking mechanism 5 are fixedly provided at both ends of the fastener chain 1 so as to face each other, and the first slider 2 and the second slider 3 are provided at the middle of the fastener chain 1 so as to face each other. When the zipper A is in a closed state, the first slider 2 and the second slider 3 are close together, the clamping head 312 of the second locking element 31 is connected with the clamping groove 2111 of the first locking element 21 in a clamping mode, at the moment, the first slider 2 and the second slider 3 are pulled randomly, the two sliders are connected with each other and move together, and the zipper A is still in the closed state; when the two sliders are pulled to the unlocking mechanism at any end, the first top plate 41 or the second top plate 51 pushes the first transmission assembly 2141 or the second transmission assembly 2142 to rotate towards a preset direction, then the slider at the side far away from the unlocking mechanism is pulled to move towards the end far away from the unlocking mechanism, the first slider 2 and the second slider 3 are separated, and the zipper A is opened. When the zipper is closed, only the sliders on either side are pulled to move towards the other slider, so that the first slider 2 and the second slider 3 are tightly close together again, and the clamping head 312 of the second locking element 31 and the clamping groove 2111 of the first locking element 21 are connected together again in a clamping manner. The zipper A of the embodiment has simple structure and easy manufacture, and people unfamiliar with the zipper structure can not know how to open the zipper A, so the anti-theft effect is good. The zipper A in the embodiment can be applied to articles such as bags, clothes, tents and the like, and has an anti-theft effect while realizing the object sealing.

The second blocking element 31 comprises a collet 312. One end of the chuck 312 is provided with a downward hook 3121, which is in snap fit with the limit component 2112. The hooks 3121 can be configured as rigid or elastic hooks. The chuck 312 is fixedly connected to the second slider body portion 32.

The first latching element 21 includes a stopper part 2112, a first body part 212, a first elastic part 213, and a first transmission part 214. A guide groove 2121 is formed in the first body portion 212, and the guide groove 2121 has two ends opened, so that two ends of the stopper 2112 protrude through the two openings of the guide groove 2121. The restricting part 2112 is provided in a rod-like configuration with a boss in the middle, as shown in fig. 23 and 24, larger than the opening size of the upper portion of the guide groove 2121, for restricting the moving position of the restricting part 2112 in the guide groove 2121 and also for compressing the first resilient part 213. In another implementation manner, the limiting component 2112 may also be configured with a bevel at the upper end, as shown in fig. 25 and 26, the first elastic component 213 is disposed below the bevel and used for driving the limiting component to move upwards when the external force disappears.

The upper part of the boss of the stopper 2112 is exposed to the outside of the first body 212 through the upper opening of the guide groove 2121, and forms an open groove with the first slider 2, and the chuck 312 is engaged with the stopper 2112. Preferably, the width of the upper end of the limiting part 2112 is larger than that of the chuck, so that the connection between the two parts is firmer. The first elastic member 213 is disposed in the guide groove 2121 and located below the boss of the stopper 2112. When the limiting component 2112 moves to the first position below the first main body part 212 under the action of external force, the first elastic component 213 is compressed by the boss; when the external force disappears, the first elastic member 213 restores the restricting member 2112 from the first position to the second position according to its own elasticity, that is, the restricting member 2112 moves upward.

It should be understood that the first elastic member 213 according to the present embodiment may be a member having elastic deformation, such as a coil spring, a torsion bar spring, and a rubber spring. The first elastic component 213 may also be an elastic sheet made of an elastic material, and the elastic sheet may have various shapes, and is separately disposed from or integrally formed with the boss of the limiting component 2112. The first transmission component 214 is connected with the bottom end of the limiting component 2112 and extends to the lower part of the first slider 2, and is used for driving the limiting component to move downwards. The top section of the first transmission component 214 is larger than the section of the limiting component 2112, and a trapezoid structure is formed by the first transmission component and the limiting component 2112. The first transmission component 214 and the limiting component 2112 may be provided as two separately connected components, or may be provided as an integrally formed structure. To facilitate the installation of the restricting part 2112 in the guide groove 2121, the first body portion 212 may be formed by fixedly coupling two parts. Preferably, the two parts are of left and right structures, and form a guide groove with two open ends after being connected.

The first unlocking mechanism 4 and the second unlocking mechanism 5 are respectively arranged at two ends of the zipper 1 in opposite directions and used for unlocking two sliders closed together so as to open the zipper A. In the present embodiment, the first unlocking mechanism 4 and the second unlocking mechanism 5 have the same structure, and the first inclined surface 43 and the second inclined surface 53 are provided at the front end portions of the first unlocking mechanism 4 and the second unlocking mechanism 5, that is, the side close to the slider, and the inclination angle may be set according to actual needs. The front ends of the first unlocking mechanism 4 and the second unlocking mechanism 5 are respectively provided with a first sliding chute 42 and a second sliding chute 52 which are arranged along the length direction or the chain extending direction of the unlocking mechanism and penetrate through the unlocking mechanism in height. The opening of the first sliding groove 42 and the opening of the second sliding groove 52 are disposed at the first inclined surface 43 and the second inclined surface 53, and are communicated with the outside. The dimension of the first sliding groove 42 and the second sliding groove 52 in the width direction of the unlocking mechanism, that is, the width of the sliding grooves is larger than the width dimension of the limiting component 2112 and is smaller than the top section dimension of the first transmission component 214. In addition, after the unlocking mechanism is installed on the fastener chain 1, the limiting component 2112 partially overlaps with the unlocking mechanism in the left view direction of the fastener chain a, so that the limiting component 2112 can enter the first sliding groove 42 and the second sliding groove 52 along the opening of the first sliding groove 42 or the second sliding groove 52 to move, the first transmission component 214 moves downwards along the first inclined surface 43 and the second inclined surface 53, and the first transmission component 214 drives the limiting component 2112 to move in the direction (downwards) for compressing the first elastic component 213 to unlock. Alternatively, the surfaces of the first transmission member 214 contacting the first inclined surfaces 43 and the second inclined surfaces 53 of the first unlocking mechanism 4 and the second unlocking mechanism 5 may be provided as planes having the same inclination angle as the first inclined surfaces 43 and the second inclined surfaces 53, that is, the cross section of the first transmission member 214 may be provided as a trapezoid.

The baffle 6 is disposed above the first locking member 21 or the second locking member 31, and the longitudinal direction thereof is parallel to the extending direction of the fastener chain 1. When the first locking element 21 and the second locking element 31 are connected together in a buckling mode, the baffle 6 shields the first locking element 21 and the second locking element 31 from the upper side of the locking elements, a pickpocket can be prevented from opening the zipper from the outer side of the zipper through tools such as a fine needle, and the anti-theft effect is better.

Thus, the first unlocking mechanism 4 and the second unlocking mechanism 5 are fixedly provided at both ends of the fastener chain 1 so as to face each other, and the first slider 2 and the second slider 3 are provided at the middle of the fastener chain 1 so as to face each other. When the zipper A is in a closed state, the first slider 2 and the second slider 3 are close together, the clamping head 312 of the second locking element 31 is connected with the limiting part 2112 of the first locking element 21 in a clamping way, at the moment, the first slider 2 and the second slider 3 are pulled randomly, the two sliders are connected with each other and move together, and the zipper A is still in the closed state; when two sliders are pulled to the unlocking mechanism at any end, the limiting component moves along the sliding groove of the unlocking mechanism, under the conditions of acting force and reacting force generated by the first transmission component 214 and the unlocking mechanism, the first transmission component 214 drives the limiting component to move towards the direction of compressing the first elastic component 213, then the slider far away from one side of the unlocking mechanism is pulled to move towards the end far away from the unlocking mechanism, the first slider 2 is separated from the second slider 3, and the zipper A is opened. When the zipper is closed, only the slider on either side is pulled to move towards the other slider, so that the first slider 2 and the second slider 3 are tightly close together again, and the chuck 312 of the second locking element 31 and the limiting part of the first locking element 21 are connected together again in a buckling manner. The zipper A of the embodiment has simple structure and easy manufacture, and people unfamiliar with the zipper structure can not know how to open the zipper A, so the anti-theft effect is good. The zipper A in the embodiment can be applied to articles such as bags, clothes, tents and the like, and has an anti-theft effect while realizing the object sealing.
