Technical Field

[0001] This utility model belongs to the field of craft packaging technology, and in particular relates to a wooden craft packaging device. Background Technology

[0002] Wooden handicrafts refer to handcrafted artworks made primarily of wood, processed through techniques such as carving, polishing, and varnishing. These handicrafts are widely loved for their natural beauty, delicate craftsmanship, and unique textures. Wooden handicrafts come in a wide variety of types, covering various aspects. To effectively protect these handicrafts from damage due to external environments and accidents during transportation, packaging devices are used for their safe transport.

[0003] Existing packaging devices typically employ common cushioning structures such as dampers, buffer springs, or foam materials to reduce damage to handicrafts caused by vibration and impact during transportation. Wooden handicrafts come in a variety of shapes, including irregular curved surfaces, openwork carvings, and sharp edges. Traditional cushioning structures, such as fixed-shaped foam or springs, are difficult to fit tightly against their surfaces, resulting in insufficient local protection. They may still be damaged by shaking or collisions during transportation.

[0004] To address these issues, we provide a packaging device for wooden handicrafts. Utility Model Content

[0005] The purpose of this utility model is to provide a packaging device for wooden handicrafts, which solves the problem that existing packaging devices cannot effectively wrap and protect wooden handicrafts during use by means of protective components and pressure inflation components.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a packaging device for wooden handicrafts, comprising an upper packaging shell and a lower packaging shell at the bottom of the upper packaging shell; a protective component is provided at the top of the lower packaging shell, the protective component including an upper protective airbag fixedly connected to the top of the upper packaging shell and a lower protective airbag fixedly connected to the bottom of the lower packaging shell; a pressure inflation component is provided at the bottom of the upper packaging shell, the pressure inflation component including a groove formed at the top of the lower packaging shell, an annular piston plate disposed inside the groove, and an air inlet pipe and a return pipe respectively connected to one side of the groove.

[0027] For a specific embodiment two, please refer to Figures 1-5 Based on the first specific embodiment, the protective component 3 further includes a conduit 303 connected to one side of the upper protective airbag 301, a threaded telescopic tube 304 connected to one end of the conduit 303, and the air inlet pipe 403 and the return pipe 404 are both connected to the threaded telescopic tube 304. The lower pressure inflation component 4 also includes a spring 405 fixedly connected to the bottom of the groove 401, the top of the spring 405 fixedly connected to the annular piston plate 402, a guide rod 406 fixedly connected to the top of the annular piston plate 402, the top of the guide rod 406 fixedly connected to the upper packaging shell 1, and one-way valves 407 respectively sleeved on the surfaces of the air inlet pipe 403 and the return pipe 404. The annular piston plate 402 is in contact with the lower packaging shell 2. A ring-shaped limiting plate 5 is provided on the top of the piston plate 402. The ring-shaped limiting plate 5 is sleeved on the surface of the guide rod 406. The ring-shaped limiting plate 5 is fixedly connected to the lower packaging shell 2. A horizontal plate 6 is fixedly connected to the front side of the lower packaging shell 2. A threaded limiting rod 7 is threadedly connected to the front side of the horizontal plate 6. A handwheel 8 is fixedly connected to the front side of the threaded limiting rod 7. A fixing plate 9 is fixedly connected to the front side of the upper packaging shell 1. A locking block 10 is fixedly connected to the bottom of the fixing plate 9. A locking groove is opened at the top of the horizontal plate 6. A limiting groove that matches the threaded limiting rod 7 is opened on the front side of the locking block 10. The locking block 10 and the locking groove are locked together. The rear end of the threaded limiting rod 7 is inserted into the limiting groove. A handle is fixedly connected to the front side of the lower packaging shell 2. An anti-slip soft pad is fixedly connected to the surface of the handle.

[0028] The operation process of this embodiment is as follows: the threaded limiting rod 7 is rotated by the handwheel 8 to move it out of the limiting groove.

At this time, the upper packaging shell 1 and the lower packaging shell 2 are separated. The gas in the upper protective airbag 301 and the lower protective airbag 302 is sucked into the groove 401 through the conduit 303, the threaded telescopic tube 304 and the return tube 404. The wooden handicrafts that need to be packaged and transported can then be placed between the upper protective airbag 301 and the lower protective airbag 302.

[0029] The upper packaging shell 1 is then pressed down, and the air at the bottom of the annular piston plate 402 is re-injected into the upper protective airbag 301 and lower protective airbag 302 through the air inlet pipe 403, threaded telescopic pipe 304, and conduit 303. During inflation, the airbags adaptively wrap around the surface of the wooden handicrafts according to their shape, providing better protection. The threaded limiting rod 7 is then screwed back into the limiting groove, completing the packaging protection. If vibration occurs during transportation, the airbags disperse the impact force through gas flow, and the spring 405 further absorbs residual shocks, achieving double buffering. Through the combination of mechanical linkage and air pressure regulation, dynamic and close protection of the wooden handicrafts is achieved, combining ease of operation, structural stability, and environmental adaptability, significantly improving transportation safety.
