As shown in fig. 1 to 3, an embodiment of the present invention provides a locking zipper, which includes a zipper tape 1, a zipper element row 2 and a locking slider 3, wherein the zipper element row 2 is disposed at a side edge of the zipper tape 1, and the zipper element row 2 includes a plurality of zipper elements; the locking slider 3 is provided on the fastener element row 2, and the locking slider 3 is movable in a direction in which the fastener tape 1 extends, so that the fastener elements are engaged with each other or disengaged from each other, and the locking slider 3 includes: the upper wing plate 31, the lower wing plate 32 and a connecting column 33 arranged between the upper wing plate 31 and the lower wing plate 32, wherein the connecting column 33 has elasticity; the locking slider 33 has a locking position where the upper wing plate 31 and the lower wing plate 32 clamp the fastener tape 1 and a movable position where the upper wing plate 31 and the lower wing plate 32 are separated from each other, and the locking slider 3 is movable between the locking position and the slide position, and when the locking slider 33 is located at the locking position, the locking slider 33 clamps the fastener tape 1. The distance between the upper wing plate 31 and the lower wing plate 32 can be adjusted through the elastic connecting column 33 to be in a locking position or a moving position, so that the locking puller 33 is determined to be clamped, fixed or movably connected to the zipper cloth belt 1, the structure is simple, the operation is simple and convenient, the number of parts is small, the production cost is low, and the production prospect is wide. In one embodiment, the connecting column 33 may be a rubber column, a resilient steel column.

The specific working process is as follows: under the condition of not giving external force, the locking slider 3 is in a locking position, and the locking slider 3 is fixed on the zipper tape 1; when it is necessary to adjust the relative position of the locking slider 3 and the fastener tape 1, the user applies an external force to the locking slider 3 to separate the upper wing plate 31 and the lower wing plate 32, and the locking slider 3 is in a movable position and is movable in the direction in which the fastener tape 1 extends to open or engage the fastener elements. When the external force disappears, the connecting column 33 recovers elastic deformation, the locking slider 3 returns to the locking position again, and the upper wing plate 31 and the lower wing plate 32 of the locking slider 3 are clamped on the zipper tape 1.

Specifically, the spliced pole is the elasticity post, and the elasticity post includes elasticity portion 331 and fixed part 332, and elasticity portion 331 one end is connected in last pterygoid lamina 31, the other end passes through fixed part 332 connects lower pterygoid lamina 32, and fixed part 332 extends to last pterygoid lamina 31 direction and forms spacing flange 3321, forms breach 3322 between the spacing flange 3321, and elasticity portion 331 can swing along breach 3322 direction. The motion direction of the connecting column 33 can be limited through the limiting flange 3321, so that the locking puller 3 stably clamps the zipper cloth belt 1, and the zipper cloth belt clamping device is stable and reliable in work, durable and long in service life. The direction of the movement of the chain belt 1 is the front-back direction, the direction of the plane where the locking slider 3 is clamped to the connecting column 33 and parallel to the clamping line is the left-right direction, the limiting flange 3321 is arranged in the front-back direction, the notch 3322 is arranged in the left-right direction, and the elastic part 331 can swing in the left-right direction through the notch 3322.

Specifically, the elastic portion 331 is detachably connected to the upper wing plate 31 and the fixing portion 332, respectively. The elastic part 331 is detachably connected with the upper wing plate 31 and the fixing part 332 respectively, so that the elastic part 331 is easy and convenient to replace, and the practicability is high.

Specifically, one side of the upper wing plate 31 is hinged with a first tail handle 311, and the connecting column 33 is provided with a second tail handle 333. Through the arrangement of the first tail handle 311 and the second tail handle 333, a user can control the relative positions of the first tail handle 311 and the second tail handle 333 to enable the locking pull head 3 to move between the locking position and the moving position, so that the length of the force arm is increased, the operation is easy and labor-saving, and the practicability is high. When the distance between the first tail handle 311 and the second tail handle 333 is increased, the locking zipper moves from the locking position to the movable position; when the distance between the first tail handle 311 and the second tail handle 333 decreases, the locking zipper moves from the active position to the locking position.

Specifically, the lower surface of the upper flap 31 and the upper surface of the lower flap 32 are provided with flexible portions, respectively. When the locking slider 3 is at the fixed position, the local load to which the locking slider 3 is subjected can be reduced by the flexible portion being in contact with the fastener tape 1 to prevent the fastener tape 1 from being wrinkled. In one particular embodiment, the flexible portion is a rubber pad.

Specifically, the elastic part is trapezoidal, and the area of the upper bottom surface of the trapezoid is larger than that of the lower bottom surface of the trapezoid. Through trapezoidal elasticity portion 331, can reduce the stress concentration coefficient of spliced pole 33 and last aerofoil 31 contact, make spliced pole 33 and last aerofoil 31 connect firm reliable, be difficult to the fracture, the practicality is strong. The surface of the elastic portion 331 contacting the upper wing 31 is an upper bottom surface, and the surface of the elastic portion 331 contacting the fixing portion 332 is a lower bottom surface.
