Specific implementation

[0030] In order to further illustrate the technical means and effects adopted by the utility model for realizing the predetermined utility model purposes and effects, the specific implementation, structure, features and effects according to the utility model are described in detail as follows by combining with the drawings and preferred embodiments.

[0031] Embodiment one

[0032] Please refer to Figures 1 to 6 It shows the specific structure of the preferred embodiment of the utility model, and it is a hemp felt fiber inner support 10.

[0033] Among them, the gap is formed between the top support 110 and the bottom support 120, which can provide more buffering for the inner support, and the goods in the containing groove 113 can be better protected, and it is suitable for packaging the products with high anti-vibration requirements.

[0034] The application provides a hemp felt fiber inner holder 10, which comprises a hemp felt fiber top holder 110; the edge of the top holder 110 is provided with a first connecting edge 112; the middle part of the top holder 110 is recessed to form a containing groove 113; the groove wall of the containing groove 113 is protruded to form a first supporting part 114 and a second supporting part 115; the edge of a bottom holder 120 is provided with a second connecting edge 121, and the wall plate of the bottom holder 120 is protruded inwardly to form a third supporting part 123 and a fourth supporting part 124; the third supporting part 123 supports the first supporting part 114; the third supporting part 123 and the first supporting part 114 are penetrated by a positioning hole 117; the fourth supporting part 124 supports the second supporting part 115; the first connecting edge 112 and the second connecting edge 121, the first supporting part 114 and the third supporting part 123, and the second supporting part 115 and the fourth supporting part 124 are adhered together. The hemp felt fiber is easier to degrade in the environment. The bottom holder 120 can be made of degradable plastic or paper, and the bottom holder 120 in the embodiment is preferably paper, such as corrugated paperboard or kraft paper. The top holder 110 and the bottom holder 120 are both made of environmentally friendly materials and are easy to degrade, which is more conducive to environmental protection. When the top holder 110 and the bottom holder 120 are combined, the positioning hole 117 is positioned, the first supporting part 114 and the third supporting part 123, and the second supporting part 115 and the fourth supporting part 124 are adhered together first, and then the first connecting edge 112 and the second connecting edge 121 are adhered together. This production method is simple and efficient, and the position is accurate. The first connecting edge 112 and the second connecting edge 121 have a certain width, and the width is between 2-3 mm, which will not waste materials. The third supporting part 123 lifts the first supporting part 114, and the fourth supporting part 124 lifts the second supporting part 115, so that a buffer gap is formed between the top holder 110 and the bottom holder 120, and the anti-vibration performance of the inner holder is better.

[0035] Preferably, the hemp felt fiber comprises hemp fibers and thermoplastic fibers; the hemp fibers are arranged on the thermoplastic fibers by using a needling process. The hemp fiber is an environmentally friendly material and is easy to degrade. In the embodiment, the first connecting edge 112 and the second connecting edge 121, the first supporting part 114 and the third supporting part 123, and the second supporting part 115 and the fourth supporting part 124 are connected together by using ultrasonic welding or hot melt adhesive bonding. The thermoplastic fiber will melt under the action of ultrasonic waves or electric heating, so that the top holder 110 and the bottom holder 120 can be directly adhered together without additional glue, and the production cost is lower.

[0036] Preferably, the outer groove wall of the accommodating groove 113 is outwardly convex to form a circular annular first supporting part 114; the inner wall of the bottom support 120 is inwardly convex to form a circular annular third supporting part 123. In production, the top support 110 and the bottom support 120 are first formed in the corresponding molds. The circular annular first supporting part 114 and the third supporting part 123 have better supporting and stabilizing properties and better buffering performance, which is conducive to self-recovery of the shape.

[0037] Preferably, the outer groove wall of the accommodating groove 113 is outwardly convex to form a rectangular second supporting part 115; the inner wall of the bottom support 120 is inwardly convex to form a rectangular fourth supporting part 124. The rectangular second supporting part 115 and the fourth supporting part 124 enable the top support 110 to obtain more uniform support, which is more conducive to protecting the articles in the accommodating groove 113 and has good anti-vibration effect.

[0038] Preferably, the second supporting part 115 is convex to form a first positioning part 116; the fourth supporting part 124 is concave to form a first positioning groove 125, and the first positioning part 116 is embedded in the first positioning groove 125. When the fourth supporting part 124 supports the second supporting part 115, the first positioning part 116 is embedded in the first positioning groove 125, which can improve the fitting accuracy between the top support 110 and the bottom support 120. At the same time, the positioning hole 117 can also provide a positioning function, which is more conducive to positioning in production and can improve the production efficiency.

[0039] Preferably, the gap between the top support 110 and the bottom support 120 is filled with a fiber bundle 126 woven together, which is one of a cotton fiber bundle 126, a hemp fiber bundle 126, and a bamboo fiber bundle 126. The fiber bundle 126 has buffering performance, which further improves the anti-vibration performance. The fiber bundle 126 can be arranged on the bottom support 120 by clamping, bonding, perforation connection, etc. After the gap between the top support 110 and the bottom support 120 is filled with the fiber bundle 126, the firmness of the inner support is better, and the anti-vibration performance is also better.

[0040] Embodiment two

[0041] Please refer to Figure 7 The application provides a packaging box 20, which comprises the hemp felt fiber inner support 10; the hemp felt fiber inner support 10 is embedded in the box body 21; a buffer pad 22 is arranged at the slot opening of the accommodating groove 113; the box cover 23 covers the box body 21, and the inner wall of the box cover 23 presses the buffer pad 22. The buffer pad 22 can be a sponge pad, a cotton pad, a foam pad, etc. When the box cover 23 covers the box body 21, the inner wall of the box cover 23 presses the buffer pad 22, and the buffer pad 22 tightly presses the product in the accommodating groove 113, so that the product does not shake in the accommodating groove 113 and does not make noise, and the anti-vibration performance and safety are better.

[0042] To sum up, the design focus of the utility model lies in that the first connecting edge 112 and the second connecting edge 121, the first supporting part 114 and the third supporting part 123, the second supporting part 115 and the fourth supporting part 124 are stuck together, so that a certain anti-vibration gap is left between the top support 110 and the bottom support 120, the anti-vibration gap can provide additional cushion for the product in the accommodating groove 113, so that the inner support has better anti-vibration performance, and the product in the packaging box 20 is safer.
