Description

Technical Field

[0001] This utility model relates to the field of nylon buckle technology, specifically a double-button torsion spring nylon rotary automatic buckle. Background Technology

[0002] In outdoor adventures, industrial operations, and emergency rescue scenarios, belt buckles, as the core component for securing nylon belts, directly impact the reliability and efficiency of equipment. As functional equipment evolves towards lighter weight and higher strength, traditional belt buckles are gradually revealing their technological limitations.

[0003] Traditional single-sided button designs are prone to deformation due to metal fatigue on one side during long-term use, leading to decreased sensitivity or even malfunction of the unlocking mechanism. Due to the low surface roughness of nylon braided straps, traditional planar friction interlocking structures cannot provide sufficient fixing force, making the strap prone to slippage and posing a safety hazard. When using nylon straps of different materials or colors on both sides, traditional belt buckles require complete disassembly and re-threading of the straps, which is cumbersome and inefficient, and cannot meet the needs of rapid switching. To solve the above problems, we propose a dual-button torsion spring nylon rotary automatic buckle. Utility Model Content

The right end of the connector is provided with a tail clip and teeth. The right side of the teeth is provided with symmetrically arranged interlocking teeth. The right end of the tail clip is provided with second pins symmetrically arranged on the top and bottom. The second pins pass through the third connecting hole symmetrically arranged on the right end of the tail clip and are inserted into the third pin hole symmetrically arranged on the top and bottom of the right end of the teeth. The rivet provided in the middle of the inner side of the tail clip passes through the fourth connecting hole in the middle of the left end of the tail clip and is inserted into the rivet hole in the middle of the right end of the connector.

[0015] Example 1

[0016] like Figures 1 to 4As shown, this utility model discloses a double-button torsion spring nylon rotary automatic buckle. The technical solution includes a main buckle 1, a crutch 2, a cover plate 3, a connecting body 4, a tail clip 5, and teeth 6. The rear right end of the main buckle 1 is provided with a cover plate 3 and a connecting body 4. The extension blocks 31 provided at the middle of the upper and lower ends of the cover plate 3 are respectively movably locked into the slots 11 symmetrically arranged at the upper and lower ends of the right end of the main buckle 1. The extension blocks 31 respectively block the crutch 2 which is rotatably installed in the slots 11. The upper and lower ends of the crutch 2 are respectively provided with double-sided buttons 21. The middle of the crutch 2 is provided with a biting part 24, which has a "sawtooth" structure. The middle of the biting part 24 is provided with a torsion spring mounting groove 22, and the torsion spring mounting... An extension rod is installed at both the upper and lower ends of the inner side of the groove 22, and a torsion spring 23 is fitted on the outer side. One end of the torsion spring 23 is in movable contact with the inner side of the torsion spring mounting groove 22, and the other end is in movable contact with the front side of the cover plate 3. The torsion spring 23 drives the crutch 2 to rotate in the slot 11 through its elastic force, so that its serrated engagement part 24 presses down to press against the surface of the nylon belt. When adjusting the length of the nylon belt, the user presses the double-sided buttons 21 of the crutch 2 at the same time, driving the crutch 2 to rotate upward along the slot 11, so that the serrated engagement part 24 disengages from the nylon belt. After the nylon belt is unrestrained, it can be pulled freely. After the user adjusts to the target length, he / she releases the double-sided buttons 21, and the torsion spring 23 returns to its original position, so that the engagement part... 24. The main buckle 1 has two first pins 7 symmetrically arranged on the right end, one above the other. The first pins 7 pass through the connecting hole 12 and the connecting hole 23 on the right end of the main buckle 1 and are inserted into the first pin hole 32 symmetrically arranged on the right end of the cover plate 3 and the second pin hole 41 symmetrically arranged on the left end of the connector 4. The right end of the connector 4 has a tail clip 5 and teeth 6. The right side of the teeth 6 has symmetrically arranged occlusal teeth. The right end of the tail clip 5 has second pins 10 symmetrically arranged on the right end. The second pins 10 pass through the connecting hole 31 symmetrically arranged on the right end of the tail clip 5 and are inserted into the third pin hole 61 symmetrically arranged on the right end of the teeth 6. The back side of the teeth 6... The protrusion 62 on the left end is movably engaged with the inner right end of the connector 4. Due to the design of the protrusion 62, when the protrusion 62 is in the same direction as the connector 4 laterally, it will be locked inside the connector 4 to ensure that the tooth 6 will not rotate along the second pin 10. Since the tail clip 5 is connected to the tooth 6 through the second pin 10, when the tooth 6 is rotated, the occlusal teeth on the back of the tooth 6 will be offset from the inner side of the tail clip 5 by a certain distance. Then, one end of the nylon band is inserted into the offset gap between the tooth 6 and the tail clip 5. Then, the tooth 6 is manually reversed to reset the tooth 6. The occlusal teeth on the back of the tooth 6 and the inner side of the tail clip 5 together clamp the nylon band, thereby completing the fixation of one end of the nylon band.A rivet 8 located in the middle of the inner side of the tail clip 5 passes through a connecting hole 42 located in the middle of the left end of the tail clip 5 and is inserted into a rivet hole 42 located in the middle of the right end of the connector 4. The connecting hole 42 is a cylindrical countersunk hole, and a compression spring 9 located inside the connecting hole 42 is fitted onto the outside of the rivet 8. By rotating the tail clip 5, the tail clip 5 rotates along the rivet 8, causing the protrusion 62 on the rear side of the tooth 6 to disengage from the "locking position" on the right side of the inner side of the connector 4. Subsequently, the tail clip 5 is pulled outward, thereby compressing the compression spring 9, unlocking the rotation lock. When the user releases the tail clip 5, the compression spring 9 returns to its original position, pushing the tail clip 5 back into place, causing the protrusion 62 of the tooth 6 to re-lock into the "locking position" on the inner side of the connector 4, thus completing the locking of the tooth 6.

[0017] The working principle of this utility model is as follows: When installing the nylon strap, first rotate the tail clip 5. The tail clip 5 rotates along the rivet 8, causing the protrusion 62 on the back side of the tooth 6 to disengage from the "clamping position" on the inner right end of the connector 4. Then, pull the tail clip 5 outward, thereby squeezing the compression spring 9 and unlocking the rotation lock. Since the tail clip 5 is connected to the tooth 6 through the second pin 10, when the tooth 6 is rotated, the cleaving teeth on the back side of the tooth 6 will be misaligned with the inner side of the tail clip 5 by a certain distance. Next, insert one end of the nylon strap into the misaligned gap between the tooth 6 and the tail clip 5. Then, manually reverse the tooth 6 to reset it. The cleaving teeth on the back side of the tooth 6 and the inner side of the tail clip 5 together clamp the nylon strap, thereby completing the fixation of one end of the nylon strap. Then, the user can rotate the tail clip 5 and the tooth 6 assembly 180 degrees to interchange the front and back of the nylon strap. After the nylon strap is flipped and adjusted, the user releases the tail clip 5, and the compression spring 9 resets, pushing the tail clip 5 back to its original position. Make the protrusion 62 of tooth 6 re-engage in the "locking position" inside the connector 4 to complete the locking of tooth 6; then, insert the other end of the nylon strap through the opening at the left end of the main buckle 1, extend it to the right along the internal channel of the main buckle 1, the nylon strap passes under the serrated biting part 24 of the crutch 2 and the front side of the connector 4 in sequence, and finally comes out from the right end of the main buckle 1. Then, according to the required length, manually pull the nylon strap to the approximate position. At this time, the nylon strap is in a free state and is not completely fixed; twist spring Spring 23 drives the crutch 2 to rotate within the slot 11, causing its serrated engagement part 24 to press downward against the surface of the nylon strap. When adjusting the length of the nylon strap, the user simultaneously presses the double-sided buttons 21 on the crutch 2, driving the crutch 2 to rotate upward along the slot 11, causing the serrated engagement part 24 to disengage from the nylon strap. After the nylon strap is unrestrained, it can be pulled freely. After the user adjusts it to the target length, they release the double-sided buttons 21, and the torsion spring 23 returns to its original position, causing the engagement part 24 to re-engage with the nylon strap.
