[0002] With the continuous development of science and technology, more and more large-scale precision instruments and equipment are being widely used. Some high-precision equipment, such as military equipment and precision instruments, have very high environmental requirements. The requirements for packaging boxes during packaging, storage, and transportation are becoming increasingly stringent, needing to meet requirements such as moisture and dust prevention to ensure that their performance is not affected after long-term storage and transportation. Furthermore, due to the excellent weather resistance, such as corrosion resistance and acid and alkali resistance, as well as the advantages of lightweight and high-strength mechanical properties, strong product design flexibility, and a wide range of molding processes, the development of packaging boxes both domestically and internationally has transitioned from the wood and metal stage to the widespread application of various composite materials. These composite material packaging boxes, characterized by their lightweight and high strength, are suitable for use in various working environments. Due to their high strength, corrosion resistance, lightweight, and high design freedom, they are widely used in military, aerospace, and precision instrument transportation fields.
[0003] However, existing composite material packaging boxes still have the following prominent problems when transporting precision equipment: on the one hand, the internal cushioning structure of the box is simple, which makes the precision instruments easy to be damaged during transportation; on the other hand, the internal fixed lining is fixedly connected to the box body, which cannot be quickly changed and adapted according to the specifications of the transported items, resulting in poor versatility. Therefore, a composite material packaging box with built-in reinforcement structure is proposed to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Reference Figure 1 - Figure 3The present invention provides an embodiment of a composite material packaging box with built-in reinforcement structure, including a box body 1, a protective mechanism 2 is provided inside the box body 1, a box cover 4 is hinged to the back of the box body 1, a shaped inner liner 5 is provided inside the box body 1, and a metal three-dimensional mesh skeleton reinforcement is embedded in the box cover 4 and the box body 1. The reinforcement is integrally formed with the outer layer of composite material. By designing the reinforcement as a three-dimensional mesh skeleton embedded in the box wall, the obstruction of resin flow by traditional protruding skeleton ribs is eliminated, and defects such as dry spots and bubbles are effectively avoided. Reference Figure 4 - Figure 5 The protective mechanism 2 includes a base plate 201, a fixed column 202 fixedly connected to the upper surface of the base plate 201, a top plate 203 fixedly connected to the upper end of the fixed column 202, a first sponge cylinder 204 sleeved on the lower outer wall of the fixed column 202, a placement rack 210 slidably connected to the outer wall of the fixed column 202, a lower spring 206 sleeved on the outer wall of the fixed column 202, a second sponge cylinder 207 sleeved on the upper end of the fixed column 202, and an upper spring 209 sleeved on the outer wall of the fixed column 202. By setting the first sponge cylinder 204 and the second sponge cylinder 207, a certain damping effect can be achieved on the spring. When the spring vibrates, the compression and rebound process of the sponge block will generate resistance due to the internal friction of the material, thereby reducing the vibration amplitude.
[0019] The bottom of the base plate 201 is fixedly connected to the inner wall of the box 1, the side wall of the top plate 203 is fixedly connected to the inner wall of the box 1, and the bottom of the shaping liner 5 is placed on the inner wall of the placement rack 210. The shaping liner 5 can limit and protect the internal items.
[0020] The outer wall of the fixed column 202 is slidably connected to a first ring plate 205, and the outer wall of the fixed column 202 is slidably connected to a second ring plate 208. The arrangement of the first ring plate 205 and the second ring plate 208 allows the spring force to be evenly applied to the sponge tube. The lower end of the lower spring 206 abuts against the top of the first ring plate 205, and the upper end of the lower spring 206 abuts against the bottom of the placement frame 210.
[0021] The lower end of the upper spring 209 abuts against the top of the placement rack 210, and the upper end of the upper spring 209 abuts against the bottom of the second ring plate 208. A latch 6 is fixedly connected to the front of the box body 1, and a latch seat 7 is fixedly connected to the front of the box cover 4. The latch 6 and the latch seat 7 make it easy to lock the box cover 4 after it is closed.
[0022] Reference Figure 2 , Figure 6The two ends of the placement rack 210 are provided with fixing mechanisms 3. The fixing mechanism 3 includes a guide groove 301, which is opened on the upper surface of the placement rack 210. A guide rod 302 is fixedly connected to the inner wall of the guide groove 301. The fixing mechanism 3 facilitates the fixing and replacement of the shaped inner liner 5, and facilitates the packaging and transportation of different items.
[0023] A retaining plate 304 is slidably connected to the outer wall of the guide rod 302. A return spring 303 is sleeved on the outer wall of the guide rod 302. One end of the return spring 303 abuts against the left wall of the retaining plate 304, and the other end of the return spring 303 abuts against the inner wall of the guide groove 301. The return spring 303 can generate a pushing force on the retaining plate 304, causing the right end of the retaining plate 304 to move above the retaining block 306. A pull plate 305 is fixedly connected to the left wall of the retaining plate 304, and a retaining block 306 is fixedly connected to the left wall of the shaping liner 5. When the shaping liner 5 needs to be replaced, the user can push the pull plate 305 to move the retaining plate 304 away from the retaining block 306. When the retaining block 306 loses the limit of the retaining plate 304, the shaping liner 5 can be directly taken out from the inside of the placement rack 210 for replacement.
[0024] Working principle: When external vibration or impact acts on the housing 1, the protection mechanism 2 starts to work: the impact force is transmitted through the housing 1 to the bottom plate 201 and the top plate 203, causing the placement rack 210 to undergo axial displacement along the fixed column 202. At this time, the lower spring 206 and the upper spring 209 undergo elastic deformation, converting kinetic energy into elastic potential energy. The first ring plate 205 and the second ring plate 208 ensure that the spring force is evenly transmitted to the first sponge cylinder 204 and the second sponge cylinder 207. The sponge material further consumes vibration energy through internal friction damping, thereby achieving protection for the items inside the shaping liner 5. The fixing mechanism 3 pushes the clamping plate 304 to slide along the guide rod 302 through the pre-tightening force of the return spring 303, so that the clamping plate 304 and the clamping block 306 on the side wall of the shaping liner 5 form a mechanical interlock, realizing tool-free quick fixing. When replacing, pull the pull plate 305 to compress the return spring 303, and the clamping plate 304 moves away from the clamping block 306, so that the shaping liner 5 can be removed.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
