Description

Technical Field

[0001] The utility model discloses a fastening type adjusting buckle and belongs to the technical field of bag accessories. Background Art

[0002] The strap adjustment buckle is a device designed to adjust the length of the strap. It allows the user to adjust the tightness of the strap according to their needs, thereby providing a more comfortable and suitable wearing experience. The mesh buckle is also known as the three-speed buckle. It is one of the common backpack accessories and is mainly used to adjust the length of the strap to meet the needs of different users.

[0003] The existing mesh buckle is usually fastened and anti-slipped by the angle difference between the two horizontal bars set in the middle. However, this stabilization method only relies on the friction between the shoulder strap and the sharp corner of the second horizontal bar set at a specific angle after the shoulder strap passes around the two horizontal bars. Therefore, once the buckle is deflected at an angle, the shoulder strap will be separated from the pressure of the sharp corner of the horizontal bar, and the shoulder strap will immediately loosen and slip off, which is very impractical. Therefore, in order to solve this problem, the utility model proposes a new solution. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] like Figures 1-5 The strap assembly is shown in Figure 1, which is a fastening type adjustment buckle, comprising a main body 1, a belt threading groove 2 for threading a shoulder strap, a first belt winding rod 3 being arranged at one end of the belt threading groove 2, and a clamping assembly being arranged at the other end, and the clamping assembly comprising a second belt winding rod 4 and a clamping piece 5, the second belt winding rod 4 being fixedly connected to the main body 1, the clamping piece 5 being rotatably arranged on the main body 1 and abutting against the second belt winding rod 4, the first belt winding rod 3 being located at a position slightly lower than the bottom of the belt threading groove 2, and the second belt winding rod 4 being located at a position slightly higher than the top of the belt threading groove 2. When a user uses the adjustment buckle, he first inserts the shoulder strap from top to bottom into an opening formed between the first belt winding rod 3 and the main body 1, then fits the first belt winding rod 3 and winds it upwards, winds it out from the opening formed between the first belt winding rod 3 and the second belt winding rod 4, then fits the second belt winding rod 4 again, inserts it between the second belt winding rod 4 and the clamping piece 5, and finally winds it out downwards from the opening between the second belt winding rod 4 and the main body 1.

[0023] The main body 1 is provided with a movable groove 7 on one end close to the second winding rod 4. The clamping piece 5 is in the shape of a slightly curved long strip as a whole, and one end is embedded in the movable groove 7, and the other end extends to the second winding rod 4. The shape of the movable groove 7 matches the end of the clamping piece 5, and the curvature of the clamping piece 5 is equal to the main body 1 on both sides of the movable groove 7, so the overall shape is more beautiful; the clamping piece 5 is provided with a mounting protrusion 8 on one end in the movable groove 7, and the main body 1 and the mounting protrusion 8 are both provided with mounting holes 9, and a rotating shaft 10 is passed through the mounting hole 9. The rotating shaft 10 and the main body 1 have an interference fit, and the rotating shaft 10 and the mounting protrusion 8 have a clearance fit, so the rotating shaft 10 can limit the clamping piece 5 so that it cannot be separated from the main body 1, and a rotation connection is formed between the clamping piece 5 and the main body 1, and the clamping piece 5 can be rotated so that the other end is away from or close to the second winding rod 4.

[0024] An elastic pressing member 6 is provided on the main body 1. The elastic pressing member 6 is specifically set as a torsion spring, and the torsion spring includes two torsion spring portions 11, a middle pressing portion 12 and end pressing portions 13. Among them, the two torsion spring portions 11 are symmetrically arranged. The two ends of the middle pressing portion 12 are respectively connected to the two torsion spring portions 11, and the end pressing portions 13 are respectively arranged at the ends of the two torsion spring portions 11 and are symmetrically aligned; the torsion spring portions 11 are respectively arranged at both ends of the mounting bump 8, the middle pressing portion 12 abuts against the clamping piece 5, a pressing plate 14 is arranged between the movable groove 7 and the tape threading groove 2, and the end pressing portion 13 abuts against the pressing plate 14. Therefore, under the pressing of the elastic pressing member 6, a force towards the second tape winding rod 4 will be maintained on the clamping piece 5, thereby ensuring the firm clamping of the backpack strap by the two, achieving a fastening effect. Even if the fastener generates an angular deflection resulting in the backpack strap disengaging from the pressing against the sharp corner of the cross bar, the clamping assembly can still maintain a good clamping effect and is not prone to loosening and slipping.

[0025] Concave patterns 15 are provided on the second tape winding rod 4, and convex patterns 16 are provided on the clamping piece 5. Both can be used to increase the friction area and friction angle with the backpack strap, thereby further stabilizing the backpack strap; arrow-shaped prompt patterns 19 are provided on the clamping piece 5, which can be used to prompt the pressing direction, making it clear at a glance for the user during use. Moreover, the clamping piece 5 can be made of fluorescent or reflective material, so that adjustment can be easily carried out even in a relatively dark place; a first reinforcing rib 17 is arranged between the mounting bump 8 and the clamping piece 5, and second reinforcing ribs 18 are arranged on both sides of the movable groove 7. Both can enhance the strength of the buckle, increasing the overall service life.

[0026] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
