Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings: Example

[0018] A fastener structure with a locking mechanism, such as Figure 1-6 As shown, it includes a male buckle 1 and a female buckle 2 that are interlocked with each other; the male buckle 1 includes a plug-in part 11, and the female buckle 2 includes a plug-in groove 21 that mates with the plug-in part 11; the plug-in groove 21 has a snap-fit ​​groove 22 that extends through and connects to the outside on both sides; the plug-in part 11 has a mounting groove that extends through both sides, and the mounting groove has an elastic buckle 3 that engages with the snap-fit ​​groove 22. The elastic buckle 3 includes two fastening blocks 31 disposed on both sides of the mounting groove. Each fastening block 31 includes a fastening part and a protrusion that is slidably disposed in the mounting groove. One end of the protrusion of the two fastening blocks 31 is limited and slidably disposed in the mounting groove of the insertion part 11 by a limiting pin 32. A first spring 33 is also disposed between the protrusions of the two fastening blocks 31. The bottom surface of the insertion part 11 is provided with a bottom groove that communicates with the mounting groove. A locking mechanism 4 for locking the elastic buckle 3 is provided in the bottom groove. The locking mechanism 4 includes a locking block 41 that is slidably disposed in the bottom groove. An unlocking rod 42 is fixedly connected to the upper side of the locking block 41. The unlocking rod 42 passes through the upper end face of the insertion part 11 and extends above it. A second spring 43 is provided between the side end face of the locking block 41 away from the elastic buckle 3 and the inner wall of the bottom groove. A cover plate 5 is fixedly provided at the opening of the bottom groove. The female buckle 2 is also provided with a clearance groove 23 for avoiding the unlocking rod 42.

[0019] Working principle: When a snap-fit ​​connection is required, the locking mechanism 4 must first be pre-unlocked. The operator pushes the unlocking lever 42 away from the female buckle 2. The unlocking lever 42 causes the locking block 41 at its lower end to overcome the elastic force of the second spring 43 and move away from the elastic buckle 3 in the bottom groove, so that the locking block 41 is completely retracted in the bottom groove, thereby making room for the retraction of the elastic buckle 3. While keeping the unlocking lever 42 pushed, the male buckle 1 is aligned with the insertion part 11 and inserted into the insertion groove 21 of the female buckle 2. During insertion, the inner wall of the insertion groove 21 presses against the two fastening blocks 31 of the elastic buckle 3. The fastening block 31 includes an outer fastening part and an inner protrusion. The outer end of the fastening part is a bevel or arc surface to facilitate contraction under pressure. Since the locking block 41 has been pre-exited, the protrusion of the fastening block 31 can slide and contract against each other along the inner wall of the mounting groove without obstruction, compressing the first spring 33, so that the insertion part 11 can smoothly slide into the depth of the insertion groove 21. When the male buckle 1 is inserted into place, that is, when the fastening block 31 is aligned with the fastening groove 22 on the female buckle 2, the unlocking rod 42 is released. At this time, the locking block 41 slides in the opposite direction under the restoring force of the second spring 43, and re-inserts into the gap between the protrusions of the two fastening blocks 31 in the mounting groove, locking the fastening block 31 in its extended position and preventing it from retracting. At the same time, the two The latching block 31 itself, under the expansion force of the first spring 33, pops outward and locks into the latching groove 22; the locking block 41 and the latching groove 22 work together to achieve double locking of the male latch 1 and the female latch 2, and the connection is firm and reliable; when separation is required, push the unlocking rod 42 away from the side of the female latch 2 again to make the locking block 41 exit the mounting groove and release the lock on the latching block 31; at this time, the latching part of the two latching blocks 31 can be pressed to make it retract and disengage from the latching groove 22, and the male latch 1 can be pulled out from the female latch 2. During the pulling process, the latching block 31 is automatically retracted by the pressure, thereby completing the separation; through the continuous action of pushing the unlocking rod 42, the process of unlocking, insertion and locking is completed in sequence, which not only ensures the smoothness of the insertion process, but also ultimately achieves reliable locking of the connection. The operation is intuitive and the security is strong.

[0020] Although this disclosure has been described in detail with reference to exemplary embodiments, it is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of this disclosure.
