A safety detection device for cargo packaging and transportation

Abstract

This utility model provides a safety detection device for cargo packaging and transportation, belonging to the technical field of transportation detection equipment. Placed above the packaging box, it consists of a transparent outer shell, a base plate, and an internal mechanical linkage structure. The base plate is fixed with adhesive. An inclined moving platform is installed inside the outer shell, with a stainless steel ball located at the bottom of the platform. Under normal conditions, the ball remains stationary. During transportation, if the box is impacted, tilted, or overturned, the ball rolls along the platform to the top, touching and releasing a needle-piercing device: a spring-driven needle tip pierces the top ink sac, causing red ink to drip onto the white absorbent cotton on the base plate, forming a clear stain. This device has no electronic components, is resistant to moisture, high temperatures, and vibration, and has a low failure rate. The transparent outer shell allows for direct observation; the absorbent cotton and ink sac are replaceable, facilitating maintenance. The overall structure is simple and low-cost, and can be applied in batches to logistics, express delivery, warehousing, and other scenarios, enabling real-time visual indication of transportation anomalies and improving the efficiency of cargo safety monitoring.

Technical Field

[0001] This utility model relates to the field of transportation inspection equipment technology, specifically to a safety inspection device for cargo packaging and transportation. Background Technology

[0002] In the field of cargo packaging and transportation, especially in logistics, express delivery, and warehousing, packaging boxes are often damaged due to vibration, tilting, or collisions during handling, loading, unloading, or transportation, leading to the destruction or loss of goods. Currently, commonly used safety detection devices rely heavily on electronic sensors or complex mechanical structures, such as accelerometers or pressure detectors. These devices have the following problems: Electronic sensors require integrated circuits and power supplies, increasing manufacturing and maintenance costs; in humid, high-temperature, or frequently vibrating transportation environments, electronic components are prone to failure, and mechanical structures are prone to malfunction due to fatigue; existing devices usually need to be fixed inside the packaging box, making disassembly and replacement cumbersome and unable to visually display the damage.

[0003] Therefore, there is an urgent need for a safety detection device that is simple in structure, low in cost, and highly reliable, which can intuitively indicate abnormal events during transportation, making it easy for operators to quickly identify and handle them. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] A safety detection device for cargo packaging and transportation, combined with an attached Figure 1 and Figure 2 As shown, it mainly includes a shell 1, a base plate 2, a sphere 3, a moving platform 4, a needle-punching device 5, and an ink sac 6. The bottom of the base plate 2 is coated with an adhesive (such as acrylic glue) for directly attaching the device to the upper surface of the packaging box. The top of the base plate 2 is fixed with the shell 1, which is made of transparent acrylic material, making it easy to observe the internal state from the outside and the material is inexpensive, reducing the manufacturing cost. The inside of the shell 1 is a hollow cavity, in which the sphere, the moving platform 4, the needle-punching device 5, and the ink sac 6 are installed.

[0020] Specifically, the mobile platform 4 is tilted, and the tilt angle is set to not less than 130° in this embodiment to ensure that the ball 3 is stably located at the bottom of the platform when the packaging box is placed normally; once the box is tilted or impacted, the ball 3 can roll along the platform.

[0021] Specifically, in this embodiment, the sphere 3 is made of stainless steel, is placed on the mobile platform 4 and initially positioned at the bottom inside the outer shell 1; the weight and material of the sphere 3 ensure that it moves along the mobile platform 4 by inertia when the packaging is impacted.

[0022] Specifically, such as Figure 3 , Figure 4 and Figure 5As shown, the needle-punching device 5 is installed on the inner top side of the housing 1 and is fixed to the housing 1 by adhesive bonding of the housing 51, which reduces production costs and provides a firm fixation. The needle-punching device 5 is also equipped with an adjusting rod 52, a needle 53, a spring 54, a limiting groove 55, a pressing block 56, and a limiting buckle 57. The adjusting rod 52 is cylindrical, with a needle 53 at one end, the needle tip facing the ink sac 6, and a spring 54 fixedly connected to the side of the rod at the other end. When the adjusting rod 52 retracts into the fixed housing 51 of the needle-punching device 5, it can compress the spring 54. The limiting groove 55 is recessed along the body of the adjusting rod 52 to form a snap-fit ​​position. The pressing block 56 is detachably snapped into the limiting groove 55 by the limiting buckle 57. In the initial state, the limiting buckle 57 is snapped into the limiting groove 55, keeping the adjusting rod 52 in a fixed position.

[0023] Specifically, the ink sac 6 is located on the top inner side of the outer shell 1, directly below the needle 53. The ink sac 6 is filled with red water-based ink. The ink sac 6 is made of elastic silicone material, which makes it easy to rupture and release ink after needle puncture.

[0024] Specifically, a white absorbent cotton 21 is laid on top of the base plate 2 to absorb the released ink and form visible stain marks.

[0025] Working principle of this utility model embodiment: When the packaging box is placed normally, the tilt angle of the moving platform 4 keeps the ball 3 stably at the bottom of the platform. When the packaging box is impacted, tilted or overturned during transportation, the ball 3 rolls or slides along the moving platform 4 under the action of inertia. The ball 3 moves to the top of the outer shell 1 and collides with the pressing block 56 of the needle punching device 5. The pressure causes the limit buckle 57 to disengage from the limit groove 55. The spring 54 then releases its elastic force, pushing the adjusting rod 52 to move towards the ink sac 6, and the needle 53 punctures the ink sac 6. After the ink is released, it drips onto the white absorbent cotton 21 above the bottom plate 2, forming a bright stain. The operator can directly observe the stain through the transparent outer shell 1, thereby judging whether an abnormal event has occurred during transportation.

[0026] During maintenance or replacement, the adjusting rod 52 can be pressed towards the inside of the fixed housing 51, causing the spring 54 to contract and be fixed by the locking buckle 57 and the locking groove 55. The ink cartridge 6 can be replaced or the angle of the moving platform 4 can be adjusted to accommodate different cartridge sizes. The stainless steel material of the ball 3 ensures long-term durability, and the white absorbent cotton 21 is replaceable to keep the indication clear.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
