Description

Technical Field

[0001] The utility model relates to a safety buckle. Background Art

[0002] Safety buckles are commonly used in rescue equipment and clothing. They can not only increase the strength of bearing heavy objects, but also provide good protection for rescue personnel. For example, protective clothing and rescue clothing with sealing effects need to meet the characteristics of anti-toxic, waterproof, sealing, and chemical resistance. Safety buckles are used to fix the safety belt worn by the personnel inside the clothing. However, the existing safety buckles have problems with strength and sealing after penetrating the clothing, which makes it difficult to meet the usage requirements. Utility Model Content

[0003] In order to solve the above problems, the purpose of the present invention is to provide a safety buckle.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a safety buckle, including an upper buckle and a lower buckle, the upper buckle is rotatably set on the upper fixed seat, and the lower buckle is rotatably connected to the lower fixed seat, and the lower surface of the upper fixed seat is docked and fixed with the upper surface of the lower fixed seat. This connection method enables the connection part to form a seamless connection structure.

[0005] Furthermore, the lower surface of the upper fixing seat is provided with a plurality of connecting tubes with threaded tubes arranged inside, the upper surface of the lower fixing seat is provided with plug holes corresponding to the connecting tubes, and the lower surface of the lower fixing seat is provided with bolt holes connected to the corresponding plug holes. The upper fixing seat and the lower fixing seat are fixed together by fixing bolts that are screwed through the connecting tubes.

[0006] Furthermore, an upper sealing ring and a lower sealing ring arranged vertically are clamped between the lower surface of the upper fixing seat and the upper surface of the lower fixing seat, and the upper sealing ring and the lower sealing ring are provided with through holes for penetrating the corresponding connecting tubes.

[0007] Furthermore, the upper surface of the upper fixing seat and the lower surface of the lower fixing seat are provided with a block-shaped protrusion structure with a triangular cross-section. The two ends of the upper buckle and the lower buckle are respectively rotatably connected to the corresponding block-shaped protrusion structure through a through-rod bolt, and the outer end of the polished rod bolt is provided with a thread screwed into the side wall of the corresponding block-shaped protrusion structure.

[0008] Furthermore, annular grooves are respectively provided on the periphery of the lower surface of the upper fixing seat and the upper surface of the lower fixing seat, and annular protruding sealing structures matching the corresponding grooves are respectively provided on the periphery of the upper surface of the upper sealing ring and the lower surface of the lower sealing ring.

[0009] Furthermore, the upper buckle and the lower buckle have high strength, rust resistance and chemical corrosion resistance.

[0010] The lower surface of the upper fixing seat of the utility model is fixed together with the upper surface of the lower fixing seat by butting against each other. This connection method forms a seamless connection structure at the connection part, which not only makes the fixing part more firm, but also improves the airtightness of the seamless connection structure. The upper surface of the lower fixing seat is provided with a plug hole for use with the connecting tube, and the lower surface of the lower fixing seat is provided with a bolt hole connected to the corresponding plug hole. The upper fixing seat and the lower fixing seat are fixed together by fixing bolts that penetrate and are screwed into the connecting tube. This fixing method not only has high fixing connection strength and is not easy to loosen, but also is faster to install and disassemble.

[0011] In addition, an upper sealing ring and a lower sealing ring arranged vertically are clamped between the lower surface of the fixing seat and the upper surface of the lower fixing seat. That is, when fixed, the upper sealing ring and the lower sealing ring are clamped and fixed by the upper fixing seat and the lower fixing seat, which not only makes the safety buckle pass through the clothing part more sealed, but also the upper sealing ring and the lower sealing ring form a firm tensioning structure at the connection part between the upper fixing seat and the lower fixing seat, increases the contact area and friction with the clothing, and also has a good anti-falling effect, ensuring the overall strength of the buckle after fixation, making the overall strength of the safety buckle higher after fixed installation, and the sealing effect of the fixed part is better, effectively ensuring safe use.
