Technical Field
[0001] This utility model relates to the field of snap-on module technology, specifically to automatic snap-on fasteners. Background Technology
[0002] Automatic snap-on buckles are devices that automatically engage or disengage by pressing. They are widely used in various products such as belts, door locks, and seat belts. The core of an automatic snap-on buckle lies in its spring structure and latching mechanism. When the user presses the buckle, the internal spring is compressed, which pushes the latch or bolt into the locking position, thus achieving automatic engagement or disengagement.
[0003] The automatic push-button buckle requires the installation and positioning of its spring assembly and buckle assembly through the buckle body and tail clip. The buckle body of some existing automatic push-button buckles is assembled from multiple parts, which is relatively complex in structure, inconvenient to disassemble and assemble, has low work efficiency during production or maintenance, and is not aesthetically pleasing in actual use. Therefore, the automatic push-button buckle is proposed to address the above problems. Utility Model Content

[0025] Please see Figure 1-8 This utility model provides a technical solution:
[0026] The automatic snap fastener includes a snap head assembly 1, a tail clip assembly 2, a push rod assembly 3, and a spring block assembly 4. The snap head assembly 1 includes a snap head body 11, with a steel pipe 12 rotatably connected to the lower protrusion of the snap head body 11. Cap studs 13 are installed at both ends of the steel pipe 12. The front of the snap head assembly 1 has a tail clip assembly 2, which includes a tail clip body 21 rotatably connected to the outside of the steel pipe 12. The left half of the tail clip body 21 has a sliding groove 22, and the rear half has a rotating groove 23. The left half of the tail clip assembly 2 has a push rod assembly 3, which includes a push rod located within the sliding groove 22 and slidably connected to the tail clip body 21. The main body 31 has an adjustment part 32 at the right end of the push rod body 31. A first spring 33 is fixedly connected in the groove on the right side of the push rod body 31. The right end of the first spring 33 is fixedly connected to the right side wall of the sliding groove 22. A screw 34 is threadedly connected in the groove on the front side of the push rod body 31. The rear half of the tail clip assembly 2 is provided with a spring block assembly 4. The spring block assembly 4 includes a spring block body 41 located in the rotating groove 23 and rotatably connected to the steel pipe 12. A transmission part 42 is provided on the front side of the spring block body 41. A buckle part 43 is provided on the upper side of the spring block body 41. A second spring 44 is fixedly connected in the groove on the lower side of the spring block body 41 and sleeved on the outer side of the lower protrusion of the spring block body 41.
[0027] The left and right ends of the steel pipe 12 are aligned with the left and right ends of the buckle body 11, respectively. The diameter of the fastening cap of the cap 13 is larger than the diameter of the rotating hole of the lower protrusion of the buckle body 11. The steel pipe 12 can be used to hinge the buckle body 11 and the tail clip body 21, and limit the movement of the spring block body 41. The tail clip body 21 is located between the two lower protrusions of the buckle body 11. The lower opening of the tail clip body 21 is provided with a toothed piece 24. Both ends of the toothed piece 24 are rotatably connected with pins 25 that are inserted into the toothed piece 24. The two pins 25 are respectively installed at the left and right ends of the tail clip body 21. The toothed piece 24 can be secured by the pins 25. The limiting mechanism uses the toothed protrusions of the toothed plate 24 to fix the material and the tail clamp body 21 together. The adjusting part 32 is a trapezoidal block with an inclined right end. The front end of the screw 34 protrudes from the front end face of the push rod body 31. The protruding part of the screw 34 is located in the front opening of the sliding groove 22. The screw 34 can prevent the push rod body 31 from coming out of the sliding groove 22. The transmission part 42 is horizontally distributed, and the latching part 43 is vertically distributed. The latching part 43 passes through the upper opening of the tail clamp body 21. The right end of the adjusting part 32 contacts the left end of the toothed plate 24. The material with the latching groove is latched by the automatically reset latching part 43.
[0028] Working process: The push rod body 31 and the adjusting part 32 of this device are integrated structures. The spring block body 41, the transmission part 42, and the buckle part 43 of this device are also integrated structures. Before use, the device needs to be assembled. First, install the first spring 33 onto the push rod body 31. Insert the push rod body 31 into the sliding groove 22, so that the screw 34 passes through the front opening of the sliding groove 22 and is installed onto the push rod body 31. Then, install the second spring 44 onto the spring block body 41. Place the spring block body 41 into the rotating groove 23. Align the lower protruding rotating hole of the buckle body 11 with the rear rotating hole of the tail clip body 21, so that the steel pipe 12 passes through the buckle body 11, the tail clip body 21, and the spring block body 41. Install the two caps 13 onto the two ends of the steel pipe 12 respectively. Finally, place the toothed piece 24 at the lower opening of the tail clip body 21, and install the two pins 25 on the left and right sides of the tail clip body 21 respectively. The pins 25 limit the toothed piece 24, thus completing the assembly of the device. When using the device, the operator can first rotate the toothed piece 24, which is limited by the pins 25, so that the toothed piece 24 is vertically distributed. Then, insert one end of the material (such as a belt) to be installed into the front opening of the tail clip body 21, and reset the toothed piece 24. The toothed protrusions of the toothed piece 24 fix the material and the tail clip body 21 together. Then, arrange the material in a circle, so that the other end of the material is inserted from the rear side of the buckle body 11 and passes through the buckle body 11. When the other end of the material presses against the buckle part 43, the user continues to push the material. The material pushes the latch 43, causing the spring block 41 in the rotating groove 23 to rotate along the steel pipe 12 limited by the cap 13. This causes the transmission part 42 to rotate, compressing the second spring 44. When the other end of the material moves a certain distance from the top of the spring block 41, the user stops pushing the material. At this time, the spring block 41 can reset with the help of the elastic force of the second spring 44. The latch 43 and the transmission part 42 reset accordingly. The slot (such as the one at the end of a belt) provided near the latch 43 at the end of the material will be locked by the latch 43. The device can automatically lock the material. To unlock, the user can press the push rod 31, causing the push rod 31 to slide completely into the sliding groove 22, thus releasing the first spring. When the lever body 31 is compressed, the adjusting part 32 will move together with the lever body 31. The end of the adjusting part 32 near the transmission part 42 is an inclined end. The adjusting part 32 can cause the transmission part 42 to move, causing the spring block body 41 to rotate, which in turn causes the latching part 43 to move, thereby releasing the latching part 43 and the material end from locking, allowing the material end to be pulled out from the buckle body 11. When the user stops pressing the lever body 31, the lever body 31 can be reset by the elastic force of the first spring 33, and the spring block body 41 can be reset by the elastic force of the second spring 44. While the lever body 31 moves, the screw 34 will also move in the front opening of the sliding groove 22. The screw 34 can prevent the lever body 31 from coming out of the sliding groove 22.This device hinges the buckle body 11 and the tail clip body 21 via a steel pipe 12 limited by the cap pin 13. Simultaneously, the steel pipe 12 limits the spring block body 41. A second spring 44 maintains the transmission part 42 and the latching part 43 in a specific position. The movement of material (such as a belt) pushes against the latching part 43, causing it to shift. The latching part 43, which automatically resets with the aid of the second spring 44, then holds the material with the latching groove. Alternatively, pressing the movable push rod body 31 moves the adjusting part 32, causing the transmission part 42 to shift, thereby releasing the latching part 43 from the material. The push rod body 31, which automatically resets with the aid of the first spring 33, resets the adjusting part 32, preventing it from obstructing the movement of the transmission part 42. This device has a simpler structure, allowing for quicker and easier assembly and disassembly, resulting in higher work efficiency during production or maintenance, and also offers a more aesthetically pleasing appearance.
