Description

Technical Field

[0001] The utility model relates to the field of D-shaped buckles, in particular to a D-shaped buckle that can be quickly locked. Background Art

[0002] D-buckles, also known as D-buckles or D-shaped buckles, are named for their D-shaped shape. They are widely used in luggage straps. Their asymmetrical shape is particularly suitable for connecting equipment such as descenders and lanyards. They are also used for connecting equipment in outdoor activities such as rock climbing and mountaineering. Common sizes include inner diameters of 1cm, 1.5cm, 2cm, 2.5cm, 3cm, and 3.8cm. The specific size should be selected based on the width of the strap or equipment.

[0003] The current D-shaped buckle structure is a combination of a U-shaped part, a threaded rod and a connecting part. The threaded rod is movably arranged in the connecting part. A spring and a groove are arranged inside the connecting part. One end of the spring is connected to the inside of the groove, and the other end of the spring is connected to the threaded rod. The threaded rod is pressed by hand to retract the threaded rod into the inside of the connecting part, thereby making a small opening in the U-shaped part for easy unlocking and then easy connection. When the hand is released, the spring generates elastic force, causing the threaded rod to extend and return to its original shape. However, when the end of the threaded rod connected to the spring is continuously subjected to large pressure, the spring will produce elastic deformation, thereby causing the spring to be compressed inside the groove. After compression, the spring may engage with the groove, causing the threaded rod to be stuck in the inside of the connecting part, making the threaded rod unable to be pulled out. External tools need to be used or the threaded rod needs to be pulled hard to pull the threaded rod out from the inside of the groove, which affects the locking and unlocking speed of the D-shaped buckle and is inconvenient to use. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technical solutions, the utility model provides a D-shaped buckle that can be quickly locked, which can effectively solve the technical problem that the threaded rod of the existing D-shaped buckle is stuck in the interior of the connecting part, resulting in the threaded rod being unable to be quickly pulled out, affecting the locking and unlocking speed.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a D-shaped buckle that can be quickly locked includes a hook piece and a movable piece, one end of the hook piece is provided with a connecting portion, the other end of the hook piece is provided with a locking head, one end of the movable piece is provided with a locking platform, the other end of the movable piece is provided with a connecting block, the locking platform includes a base plate integrally formed with the movable piece and locking blocks arranged on both sides of the base plate, the surface of the locking block is provided with a plurality of circular grooves, the surface of the locking head is provided with a plurality of protrusions that match the circular grooves, and the locking head is locked with the locking block.

[0006] Furthermore, the connecting portion is provided with a rotating shaft, and the connecting block is rotationally connected to the rotating shaft.

[0007] Furthermore, the surface of the barb is smooth.

[0008] Furthermore, a plurality of anti-slip grooves are provided on the surface of the movable part.

[0009] Furthermore, a rubber pad is bonded to the surface of the barb piece.

[0010] Furthermore, the barb piece and the movable piece are both made of metal.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the D-shaped buckle of the present invention can be quickly locked, and the fast locking and unlocking of the D-shaped buckle is achieved through the design of the locking block with a circular groove set on the locking platform and the matching protrusions on the locking head, which simplifies the locking and unlocking operation process, allowing users to quickly and conveniently connect or disconnect the D-shaped buckle, greatly improving the locking and unlocking speed.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figure 1-Figure 4As shown, a D-shaped buckle that can be quickly locked includes a hook member 1 and a movable member 3, one end of the hook member 1 is provided with a connecting portion 9, the other end of the hook member 1 is provided with a snap head 5, one end of the movable member 3 is provided with a snap platform, the other end of the movable member 3 is provided with a connecting block 11, the snap platform includes a base plate 6 integrally formed with the movable member 3 and snap blocks 7 arranged on both sides of the base plate 6, the surface of the snap block 7 is provided with a plurality of circular grooves 8, the surface of the snap head 5 is provided with a plurality of convex points 12 that match the circular grooves 8, the snap head 5 is snapped with the snap block 7, the connecting portion 9 is provided with a rotating shaft 10, the connecting block 11 is rotatably connected with the rotating shaft 10, the surface of the hook member 1 is a smooth surface, the surface of the movable member 3 is provided with a plurality of anti-slip grooves 4, the hook member 1 is bonded with a rubber pad 2, and the hook member 1 and the movable member 3 are both made of metal. The rotating connection design of the rotating shaft 10 on the connecting part 9 and the connecting block 11 enables the movable member 3 to rotate flexibly within a certain angle range, thereby increasing the flexibility of the D-type buckle. The smooth surface of the hook member 1 improves the overall appearance texture and makes the D-type buckle more beautiful. The anti-slip groove 4 provided on the movable member 3 can increase the friction between the user's hand and the D-type buckle, making it more stable and reliable during operation, and reducing the risk of accidental falling off or misoperation due to hand slippage.
