Description

Technical Field

[0001] The utility model relates to the field of buckles, in particular to high-strength hardware buckles. Background Art

[0002] Buckles, also known as dog buckles, lobster buckles, hook buckles, are mainly used at the ends of the straps of suitcases or hanging ropes, so that the straps can be conveniently fixed on D buckles or other round buckles. According to different shapes and functions, buckles can also be divided into various types, such as D-rings, ladder buckles, rope buckles, etc., and each type has its specific application scenarios and advantages.

[0003] Existing buckles generally consist of a movable part, a fixed part and a connecting rod. The connecting rod is used to connect the movable part and the fixed part. The fixed part is usually a fixed structure in various shapes such as circular, square, semi-circular, oval, etc. The fixed part is used to fix with external ropes, etc., and the movable part can be opened for convenient buckling. Existing buckles are usually made of plastic and rubber materials, with low structural strength. When the surface of the buckle is subjected to external friction and impact, the pressure borne by the surface of the buckle is large, which easily causes it to break or deform. When the buckle bears a load exceeding its designed bearing capacity, it will also cause it to break or deform. For example, when lifting heavy objects, using a load capacity exceeding the limit, or hanging too many items on the buckle will cause the buckle to deform. Incorrect operation methods may also cause the buckle to break or deform. For example, using too much force when inserting or removing the buckle, or operating the buckle when it is not fully locked, resulting in the deformation or breakage of the buckle. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art solutions, the utility model provides a high-strength hardware buckle, which can effectively solve the technical problems that the existing buckles have low overall strength and are prone to breakage and deformation.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a high-strength hardware buckle, including a movable part, a fixed part and a connecting rod. The movable part and the connecting rod are integrally formed. The movable part includes a barbed rod and a movable rod. The surfaces of the barbed rod are respectively fixedly sleeved with a first fixing ring and a second fixing ring. The fixed part includes a bottom plate, a connecting block and a semi-circular rod. The bottom plate is fixedly arranged at both ends of the connecting block. A metal plate is welded on the surface of the bottom plate. The semi-circular rod is fixedly arranged at the bottom of the bottom plate. The surface of the semi-circular rod is fixedly sleeved with a third fixing ring.

[0006] Further, a long screw is arranged at the bottom of the connecting block. The long screw extends into the interior of the connecting rod. The connecting block is threadedly connected with the connecting rod through the long screw.

[0007] Further, one end of the movable rod is rotatably connected to the barbed rod through a rotating shaft, and the other end of the movable rod contacts the barbed rod.

[0008] Further, a fixing block is fixedly arranged on the surface of the movable rod, a placing plate is fixedly arranged on the surface of the barbed rod, a chute is arranged inside the barbed rod, a rotatable sliding rod is arranged on the fixing block through a rotating shaft, one end of the sliding rod is slidably connected to the chute, a spring is arranged on the top surface of the placing plate, one end of the spring is fixedly connected to the placing plate, and the other end of the spring is fixedly connected to the sliding rod.

[0009] Further, the first fixing ring, the second fixing ring and the third fixing ring are all made of metal materials.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: The high-strength hardware buckle of the present utility model is formed by integrally molding between the movable part and the connecting rod, reducing the joints between components. By sleeving the first fixing ring and the second fixing ring on the surface of the barbed rod, sleeving the third fixing ring on the surface of the semi-circular rod, and welding a metal plate on the surface of the bottom plate, the overall strength is higher, thus significantly improving the overall structural strength, making the hardware buckle more stable when bearing external forces and not easily breaking or deforming.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] As Figures 1 - 3 shown, the high-strength hardware hook includes a movable member, a fixed member, and a connecting rod 6. The movable member and the connecting rod 6 are integrally formed. The movable member includes a barbed rod 1 and a movable rod 2. A first fixing ring 4 and a second fixing ring 5 are respectively fixedly sleeved on the surface of the barbed rod 1. The fixed member includes a bottom plate 7, a connecting block 9, and a semi-circular rod 11. The bottom plate 7 is fixedly arranged at both ends of the connecting block 9. A metal plate 8 is welded on the surface of the bottom plate 7. The semi-circular rod 11 is fixedly arranged at the bottom of the bottom plate 7. A third fixing ring 12 is fixedly sleeved on the surface of the semi-circular rod 11. A long screw 10 is arranged at the bottom of the connecting block 9. The long screw 10 extends into the interior of the connecting rod 6. The connecting block 9 is threadedly connected to the connecting rod 6 through the long screw 10. By threadedly connecting the connecting block 9 and the connecting rod 6 with the long screw 10, the firmness and stability of the connection are ensured, making the installation and disassembly process of the hardware hook simple and fast, facilitating the installation or disassembly of the fixed member. One end of the movable rod 2 is rotatably connected to the barbed rod 1 through a rotating shaft. The other end of the movable rod 2 contacts the barbed rod 1. A fixed block 15 is fixedly arranged on the surface of the movable rod 2. A placement plate 16 is fixedly arranged on the surface of the barbed rod 1. A chute 13 is opened in the interior of the barbed rod 1. The fixed block 15 is provided with a rotatable sliding rod 3 through a rotating shaft. One end of the sliding rod 3 is slidably connected to the chute 13. A spring 14 is arranged on the top surface of the placement plate 16. One end of the spring 14 is fixedly connected to the placement plate 16. The other end of the spring 14 is fixedly connected to the sliding rod 3. The first fixing ring 4, the second fixing ring 5, and the third fixing ring 12 are all made of metal material. The movable rod 2 is rotatably connected to the barbed rod 1 through a rotating shaft, enabling the movable rod 2 to rotate flexibly, thereby adapting to connection requirements at different angles and directions, and improving the applicability and flexibility of the hardware hook.

[0018] The high-strength hardware buckle of this embodiment is formed by integral molding between the movable part and the connecting rod 6, reducing the seams between components. By sleeving the first fixing ring 4 and the second fixing ring 5 on the surface of the barb rod 1, sleeving the third fixing ring 12 on the surface of the semi-circular rod 11, and welding the metal plate 8 on the surface of the bottom plate 7, the overall strength is higher, thus significantly improving the overall structural strength, making the hardware buckle more stable when bearing external forces, not easily broken or deformed. The spring 14 enables the sliding rod 3 to reset to the initial position for convenient next use.
