Description

Technical Field

[0001] This utility model belongs to the field of safety buckle technology, specifically relating to a five-point safety buckle. Background Technology

[0002] Safety buckles, commonly used in strollers, child seats, and seatbelt systems, serve to securely fasten key parts of the body through multi-point connections, thereby enhancing user safety during movement and collisions. Currently, common safety buckles include three-point and five-point structures. Five-point safety buckles, due to their wider coverage and stronger stability, have gradually become an important component in child safety protection.

[0003] However, existing five-point safety buckles still have many shortcomings in terms of structural design and ease of use. On the one hand, the unlocking structure of some products is complex, requiring users to unlock multiple connectors sequentially, which is time-consuming and laborious, especially in emergencies where it is difficult to complete the unlocking operation in time, posing a safety hazard. On the other hand, some safety buckles have problems with connection stability, such as the connecting parts being prone to shaking, not locking securely, and easily becoming stuck or failing to unlock after prolonged use, affecting the user experience and safety performance.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

Detailed Implementation

[0022] like Figures 1 to 6 As shown, a five-point safety buckle includes a central buckle body 10, with several connecting fasteners 20 connected to its side. Several fastener slots 11 are formed on the side of the central buckle body 10, and the connecting fasteners 20 are correspondingly engaged in these slots. A button mounting groove 12 is recessed in the center of the central buckle body 10, communicating with the fastener slots 11. An unlocking button 30 is installed in the button mounting groove 12, and it abuts against the connecting fasteners 20. In use, pressing the unlocking button 30 pushes the connecting fasteners 20, causing them to pop out of the fastener slots 11, thus quickly unlocking the central buckle body 10 and the connecting fasteners 20. This design is simple, easy to operate, and facilitates the disassembly, assembly, and maintenance of the safety buckle.

[0023] In practical implementation, one end of the connecting fastener 20 is provided with a flexible connecting buckle part 21, and the interior of the connecting buckle part 21 is provided with a flexible fastener spring part 22 for realizing the connection and locking functions. The upper inner side of the fastener slot 11 is provided with a connecting buckle 111, and the lower edge of the unlock button 30 is provided with an annular unlocking ring edge 31. The annular structure is conducive to the simultaneous action of multiple connecting fasteners 20. During installation, the connecting buckle part 21 is inserted into the corresponding fastener slot 11, and the connecting buckle part 21 and the connecting buckle 111 are fastened together. During the insertion process, the connecting buckle 111 pushes the end of the fastener spring part 22 downward to compress it. At the same time, the end of the connecting buckle part 21 is located below the unlocking ring edge 31 and is in the ready-to-release position. During use, when the user presses the unlock button 30, the unlock ring edge 31 moves downward as a whole, which pushes the ends of the connecting buckles 21 of several connecting fasteners 20 downward, thereby causing the fastener springs 22 to press down and disengage from the connecting buckle 111, thus realizing the quick unlocking of the connecting fasteners 20 and the central buckle 10. This structure is reasonably designed and has good operational convenience and safety, and is suitable for various application scenarios that require quick locking and unlocking, such as strollers, child seats, and seat belts.

[0024] In practical implementation, the inner surface of the button mounting slot 12 is provided with a first spring recess 121, and the interior of the unlock button 30 is provided with a second spring recess 32. A return spring 40 is connected between the first spring recess 121 and the second spring recess 32. In use, when the user presses the unlock button 30, the unlock button 30 moves downward while compressing the return spring 40, thereby pushing the multiple connecting fasteners 20 to achieve the unlocking action. When the user releases the unlock button 30, under the elastic force of the return spring 40, the unlock button 30 automatically returns to its initial position.

[0025] In practical implementation, the inner side of the button mounting groove 12 is uniformly provided with a plurality of positioning protrusions 122, and the inner side of the unlock button 30 is uniformly provided with a plurality of positioning through pins 33 that are adapted to the positioning protrusions 122. The plurality of positioning protrusions 122 and the plurality of positioning through pins 33 are connected one-to-one. In use, the cooperation between the positioning protrusions 122 and the positioning through pins 33 can effectively limit the movement trajectory of the unlock button 30, ensuring that the unlock button 30 maintains stable vertical movement during the pressing process, avoiding deviation, tilting or rotation, and improving the smoothness of the unlocking operation and the overall reliability of the structure.

[0026] In practical implementation, the fastener slot 11 has symmetrical positioning slots 112 on both sides of its inner side, and the connecting fastener 20 has symmetrical positioning blocks 23 on both sides of one end. When the connecting fastener 20 is engaged in the fastener slot 11, the two positioning blocks 23 are correspondingly inserted into the two positioning slots 112. In use, this positioning structure effectively prevents the connecting fastener 20 from wobbling left and right or rotating and shifting in the locked state, thereby improving the stability of the overall structure and the reliability of the connection. At the same time, this plug-in engagement method facilitates quick assembly and ensures connection accuracy.

[0027] In practical implementation, the connecting fasteners 20 include two shoulder strap fasteners 24 and two waist belt fasteners 25, and the fastener slots 11 include two first connecting slots 113 and two second connecting slots 114. The two first connecting slots 113 are respectively located on the left and right sides of the central buckle body 10 for connecting with the shoulder strap fasteners 24, and the two second connecting slots 114 are respectively located on the lower sides of the central buckle body 10 for connecting with the waist belt fasteners 25. Correspondingly, the two shoulder strap fasteners 24 are respectively engaged in the two first connecting slots 113, and the two waist belt fasteners 25 are respectively engaged in the two second connecting slots 114, forming a symmetrical multi-point connection structure. The upper side of the central buckle body 10 is provided with a main strap connection part 13 for connecting the main load-bearing belt or chest strap, which is structurally integrated with the shoulder strap fasteners 24. During use, the shoulder strap buckle 24 and the waist belt buckle 25 are connected to the safety belt strips on the shoulder and waist respectively. The central buckle 10 enables centralized locking and unified unlocking operations, ensuring that the safety buckle can maintain a stable and reliable connection when subjected to multi-directional tension, making it easy to wear and remove.

[0028] In summary, the central buckle body 10 has several connecting fasteners 20 connected to its side, and several fastener slots 11 are provided on the side of the central buckle body 10. The connecting fasteners 20 are correspondingly engaged in the fastener slots 11. The central buckle body 10 has a recessed button mounting groove 12 in its center, which communicates with the fastener slots 11. An unlocking button 30 is installed in the button mounting groove 12, and the unlocking button 30 abuts against the connecting fasteners 20. The five-point safety buckle of this utility model can quickly unlock the central buckle body and the connecting fasteners. It has a simple structural design, is easy to operate, and facilitates the disassembly, assembly, and maintenance of the safety buckle, providing good operational convenience and safety.
