[0001] The utility model relates to the field of fastener products, in particular to a quick-release buckle. Background Art

[0002] At present, most of the buckles used on clothes and backpacks are flat buckles, which include a male buckle and a female buckle. The side of the female buckle is provided with a slot. The male buckle uses the wedge-shaped hook on its side to be embedded in the slot to play a connecting role. When it needs to be opened, the male buckle can be removed from the female buckle by pinching it. It is the most widely used. However, the above-mentioned buckle structure has the following defects when used: it is impossible to determine the position of the wedge-shaped hooks on both sides of the male buckle and it is easy to fail to open the buckle due to thick gloves when pressing; the existing buckles are used on the shoulders and waist of bulletproof vests, occupying a large loading space, and the joints are hard, affecting comfort; the existing buckles on the market require two hands to operate to open the buckles, which is cumbersome.

[0046] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0047] See Figure 1-11As shown in the figure, a quick-release buckle provided by the utility model specifically includes at least one fastener. One or more webbing socket grooves are respectively provided on the left and right sides of the fastener. An opening groove extends outward from one side of the webbing socket groove. In the embodiment provided by this solution, two fasteners are provided, specifically the first fastener 100 and the second fastener 200. The first fastener 100 and the second fastener 200 are matched by a sliding plug-in method. It should be noted that even if this solution only has one fastener in terms of quantity, that is, the sliding cooperation of the fasteners on both sides is not realized, the webbing can still be slid inward through the opening groove and fixed to the webbing socket groove. However, in specific practice, we found that using two cooperating fasteners is more convenient for disassembling and assembling the webbing on both sides. Therefore, two components are used for illustration in this embodiment;

[0048] Specifically, the first fastener 100 is provided with at least one or more first opening grooves 103, and the first fastener 100 is provided with first webbing socket grooves 110 that match the number of the first opening grooves 103; the second fastener 200 is provided with at least one or more second opening grooves 203; the second fastener 200 is provided with second webbing socket grooves 210 that match the number of the second opening grooves 203. It should be noted that if this solution is only used in the cooperation of ordinary luggage, only one first opening groove 103, first webbing socket groove 110 and a corresponding second opening groove 203 and second webbing socket groove 210 on the other side can be set. However, if this solution is used in application scenarios such as tactical vests (bulletproof vests) that require connecting webbings in multiple directions, see the appendix Figure 3 , then two or more first opening grooves 103, first webbing socket grooves 110 and a corresponding second opening groove 203 and second webbing socket groove 210 on the other side can be set to achieve an effective reinforcement effect;

[0049] In order to effectively limit and reinforce the webbing after assembly, special designs are made in the first webbing socket groove 110 and the second opening groove 203. First limiting bumps 104 and second limiting bumps 204 extending in the direction towards the middle are respectively provided at the opening ends of the first webbing socket groove 110 and the second opening groove 203. It should be noted that the number of the first limiting bumps 104 and the second limiting bumps 204 is set to one or more. That is, when one first limiting bump 104 and one second limiting bump 204 are set, the webbing can also be well limited inside the first webbing socket groove 110 and the second opening groove 203 without deviation. However, considering aesthetics and the symmetry of the force, the preferred solution is to respectively set the first limiting bumps 104 and the second limiting bumps 204 at both opening ends of the first webbing socket groove 110 and the second opening groove 203. Through the design of multiple bumps, the effect of strengthening the fixation of the internal webbing and preventing it from falling off is achieved;

[0050] In order to better insert the webbing, the opening groove can be limited in shape. Of course, when the opening is set to a shape such as a 1-shaped, U-shaped, or Y-shaped shape, it can be protected by this solution. In actual use, our preferred solution is to set the first opening groove 103 and the second opening groove 203 to be V-shaped openings. The V-shaped opening is a small opening toward the middle and a large opening toward the outside. The large opening set outward is to facilitate the insertion of the webbing, and the small opening set inward is to prevent the inserted webbing from running out easily. Similarly, the same type can also be a Y-shaped opening groove design, a U-shaped opening groove design, etc.

[0051] In order to make the first fastener 100 and the second fastener 200 better achieve sliding and locking cooperation when in use, the first fastener 100 is provided with a matching cavity 102 recessed inwardly, a limiting block 109 is provided on one side of the matching cavity 102, and a circular arc-shaped boss 202 is provided on one side of the second fastener 200. During assembly, the boss 202 is inserted into the matching cavity 102, and a limiting groove 206 is provided in the center of the second fastener 200. At the same time, at least one clamping step 111 protruding inwardly is provided on the matching cavity 102 of the first fastener 100, and an inserting groove 201 matching the clamping step 111 is provided on the outer surface of the second fastener 200, and a convex block 205 matching the clamping of the clamping step 111 is provided above the inserting groove 201. Specifically, during assembly, the limiting block 109 slides into the limiting groove 206 and is stuck on the inner side of the limiting groove 206;

[0052] Since no additional locking fastener is provided in the present solution, the tension degree needs to be limited on the first fastener 100 and the second fastener 200. Therefore, in addition to providing a breaking piece 101 in the direction of the first fastener 100 toward the second fastener 200 to facilitate better breaking of the breaking piece 101, the breaking piece 101 is connected to the inner pressing plate 108, and the pressing plate 108 is provided with the limiting block 109 on the inner side of the matching cavity 102. The left and right sides of the pressing plate 108 are symmetrically provided with middle reinforcing ribs 106 for limiting its tension force, so as to adjust the tension force in the middle. When the first fastener 100 and the second fastener 200 are matched, it can

[0053] The tension locking effect is automatically achieved, that is, the first fastener 100 and the second fastener 200 cannot be easily disassembled without external force. Similarly, in order to enhance the tension strength of the edge of the first fastener 100, the first fastener 100 is symmetrically provided with edge reinforcement ribs 107 for increasing the tension strength. The edge reinforcement ribs 107 are arranged on the outside of the middle reinforcement rib 106 to prevent the second fastener 200 from being loosely fastened at the edge.

[0054] In practice, in order to facilitate the separation of the first fastener 100 and the second fastener 200, the breaking piece 101 is arranged to be arc-shaped and protrudes outward, so as to facilitate the labor-saving separation of the first fastener 100 and the second fastener 200. The breaking piece 101 is provided with a rope threading hole 105 for threading a rope, and the rope can be threaded through when in use, which can also achieve a more labor-saving effect.

[0055] Working principle:

[0056] When the utility model is used, the first fastener and the second fastener are slid in with each other, the ground matching cavity on the first fastener is aligned with the convex platform of the second fastener, the clamping step is matched with the convex block, and the plug-in slot is slid in along the clamping step, and the central pressing plate is pushed upward during the sliding process, so that the first fastener and the second fastener are continuously brought close to each other. Figure 12 As shown in FIG. 1 , when the second fastener slides to a position aligned with the first fastener, that is, the second fastener is Figure 1-3 When the first and second fasteners are in the state of being pressed together, the limiting groove in the second fastener cooperates with the limiting block inside the pressing plate of the first fastener to realize limiting clamping, so that the first and second fasteners cannot be pushed forward or misaligned again without the action of external force; when the first and second fasteners need to be separated, the breaking piece is pulled upwards so that the limiting block on the pressing piece is no longer pressed in the limiting groove, and the two fasteners can be separated by gently pushing them;

[0057] When assembling the webbing, one side of the sewn webbing is wound around the first opening groove and reversed after entering the first opening groove, so that one side can be sleeved in the first webbing sleeve groove (half section), and the other side is pushed into the other side of the first opening groove (also half section) along the horizontal direction, thus completing the assembly of the webbing. It should be noted that four webbing sleeve grooves are used in the present scheme, wherein the webbing threading method in each webbing sleeve groove is consistent. When the webbing sleeve is completed, the corresponding protrusions on the groove can enhance the fixation and prevent it from falling off, making the sleeve and removal of the webbing more convenient and quick.

[0058] It should be emphasized that the principles not described in detail in this specification belong to the prior art known to professionals in this field.

[0059] The exemplary implementation scheme of the present disclosure is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
