Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 2, fig. 2 is a schematic diagram of an overall structure of an embodiment of the present invention.

The utility model provides an among the concrete embodiment, the quick interlock structure of pull head dislocation prevention mainly includes lower end seat 1, bolt through-hole 101, pull head 2 and guide fin 3.

The lower stop seat 1 is one of the components of the lower stop piece of the zipper and is arranged at the bottom of one of the chains, and the other component of the lower stop piece of the zipper is a lower stop bolt and is arranged at the bottom of the other corresponding chain.

The lower stop seat 1 is provided with a bolt through hole 101, and the bolt through hole 101 is mainly used for being matched with a lower stop bolt. The puller 2 is arranged on the chain and is generally positioned on the chain provided with the lower stop seat 1, one side surface of the puller 2 is slidably sleeved on the chain, when the zipper is not engaged, the puller 2 can freely slide up and down on the chain, and of course, due to the influence of gravity factors, the puller 2 is generally positioned at the bottom end of the chain, namely the position of the lower stop seat 1.

Importantly, the side wall of the lower stop 1 is provided with a guide fin 3, the inner side wall of the guide fin 3 is mainly used for abutting against the outer side wall of the slider 2, so that when the slider 2 slides to the position of the lower stop 1 at the bottom of the chain under the action of gravity, the orientation of the lower stop is corrected to be parallel to the length direction of the chain under the abutting action of the guide fin 3. Or, when the slider 2 slides to the bottom position of the zipper, the side wall of the guide tab 3 abuts against the side wall of the slider 2, so that the movement direction of the slider 2 is guided, and the slider 2 is prevented from being deflected due to the influence of factors such as vibration during the movement process, so that the movement direction of the slider 2 tends to face the length direction of the zipper.

Thus, the movement of the slider 2 is corrected or guided by the guide fin 3, and the slider 2 is ensured to face parallel to the length direction of the chain when sliding down to the lower stop seat 1 at the bottom of the chain. Therefore, the pull head dislocation-preventing rapid meshing structure provided by the embodiment can prevent the situation that the pull head 2 is obliquely locked at the starting end of the chain under the situation that the zipper is not meshed, ensures that the pull head 2 always faces the correct direction, is convenient for a user to use, saves the time for the user to operate the zipper, and improves the user use experience.

As shown in fig. 3, fig. 3 is a specific structural diagram of the lower stop shown in fig. 1.

In a preferred embodiment concerning the guide tab 3, the guide tab 3 may be provided on the side wall of the lower stop 1 for this purpose, since the inner side wall of the guide tab 3 has to abut against the side wall of the slider 2. Specifically, since the slider 2 is generally of an axisymmetric structure, both side walls of the slider 2 can be used to abut against the side walls of the guide tabs 3. For this reason, guide fin 3 can set up on the inside wall of lower stop seat 1, also can set up on the lateral wall of lower stop seat 1, perhaps guide fin 3 can set up simultaneously on the interior lateral wall of lower stop seat 1, can be simultaneously with the both sides lateral wall butt of pull head 2, and the direction effect is better.

Further, in consideration of workability, design regulation and beauty of the slide fastener, if the guide wing 3 is provided on the outer side wall of the lower stop 1, the guide wing 3 is exposed when the slide fastener is not engaged, and easily collides with another chain or a lower stop pin thereon, resulting in abrasion. For this reason, in the present embodiment, it is preferable that the guide wing 3 is provided on the inner side wall of the lower stopper 1 so that the guide wing 3 is not exposed regardless of whether the zipper is engaged or not. Meanwhile, in order to prevent the user from breaking or damaging the guide wing pieces 3 inadvertently, it is further preferable in this embodiment that the guide wing pieces 3 are disposed at the bottom of the side wall of the lower stop seat 1, that is, the guide wing pieces 3 are located at the lower half portion of the lower stop seat 1, covered by the chain cloth tape, and also abutted against the bottom of the side wall of the slider 2.

In order to improve the guiding and correcting effect of the guide wing piece 3 on the moving direction of the slider 2, in this embodiment, the inner side surface of the guide wing piece 3 is specifically a curved surface attached to the outer side wall surface of the slider 2. Of course, to ensure that the slider 2 avoids the formation of movement interference when it comes into abutment with the guide tab 3, the inside surface of the guide tab 3 may be embodied as a smooth surface.

As shown in fig. 4 and 5, fig. 4 is a detailed structural view of the guide vane shown in fig. 3, and fig. 5 is a plan view of fig. 4.

In addition, after the correction and guide action of the guide fin 3, the direction of the slider 2 is correct, but during long-term use, the slider 2 may deviate to a certain degree during the shaking of the clothes along with the influence of factors such as violent movement of a user or surface abrasion, and in order to keep the slider 2 in the correct direction for a long time, the retaining action of the correct direction of the slider 2 is strengthened, and the guide fin 3 of the embodiment is further improved.

Specifically, in the present embodiment, a plurality of elastic teeth 4 are additionally provided on the inner side wall of the guide vane 3, and meanwhile, a plurality of elastic teeth 4 are correspondingly additionally provided on the surface of the corresponding side wall of the slider 2. Of course, the elastic teeth 4 are evenly distributed in the length direction on both the guide tab 3 and the slider 2, and may be engaged or meshed with each other. With such an arrangement, the resilient teeth 4 between the slider 2 and the guide tab 3 are engaged with each other to provide a certain degree of locking effect on the slider 2, thereby securing the slider in the current orientation. Meanwhile, the engagement of the elastic teeth 4 between the slider 2 and the guide tab 3 belongs to soft locking control, and the slider 2 and the guide tab 3 can easily generate elastic deformation, so that when a user intentionally applies force to pull the slider 2, the elastic teeth 4 of the slider 2 and the guide tab can generate elastic deformation through positive pressure during mutual extrusion to further disengage from an engaged state, thereby ensuring that the slider 2 can smoothly slide.

In a preferred embodiment of the elastic teeth 4, the elastic teeth 4 may be in the shape of a semicircle or an isosceles trapezoid, wherein the edge of the former is arc-shaped, so that the force-releasing transition effect is more easily generated, the locking effect is weaker when the teeth are engaged, but the unlocking operation is easier, and the teeth are easy to pull by a user, and are suitable for users with low age or strength; the edge of the latter is plane, so the force is not easy to be removed, the locking effect is strong when the locking device is engaged, but the locking device needs to use larger force when the locking device is unlocked, and the locking device is suitable for users with age or larger force. Of course, the specific shape of the elastic teeth 4 is not limited to the above two shapes, and other shapes such as a rectangle, a sector, a triangle, etc. may be equally employed. Generally, the occlusion depth of two adjacent elastic teeth 4 can be 1-2 mm.

As shown in fig. 6, fig. 6 is another specific structural schematic diagram of the lower stop shown in fig. 1.

In addition, in view of the same considerations, the present embodiment improves the lower stopper 1 so that the slider 2 can be more stably maintained in the correct orientation after undergoing the correcting and guiding action of the guide tab 3. Specifically, in the present embodiment, an installation groove 102 is formed in the upper end surface of the lower stopper 1, and the installation groove 102 is mainly used for accommodating the bottom end of the slider 2. With such an arrangement, when the slider 2 slides down, it will fall into the mounting groove 102 correctly in the direction after being abutted by the guide fin 3, and thus be stably mounted in the mounting groove 102 for a long time.

Further, the mounting groove 102 may be a rectangular groove, and is mainly used for accommodating the straight section 201 portion of the bottom of the slider 2. So set up, after slider 2 landing to mounting groove 102, the both sides lateral wall of mounting groove 102 will sticis on the both sides side of straight section 201 of slider 2 bottom, presss from both sides tight slider 2. At this time, no matter what kind of external vibration influences the slider 2, since the two side walls of the mounting groove 102 clamp the bottom straight section 201, the transverse motion component caused by the vibration can be always cancelled, so that the slider 2 only has the motion trend along the longitudinal direction (or the vertical direction), and thus the orientation of the slider 2 is always ensured to be correct.

The embodiment also provides a zipper, which mainly comprises a zipper and a slider anti-dislocation quick meshing structure arranged on the zipper, wherein the main content of the slider anti-dislocation quick meshing structure is the same as the related content, and the details are not repeated.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
