Description

Technical Field

[0001] This invention relates to the field of packaging structure technology, and specifically to a knife packaging box. Background Technology

[0002] With the continuous development of precision machining technology, micro-diameter CNC cutting tools are widely used because they can achieve high-precision machining of micro-structures. In some scenarios, tool packaging often uses rigid plastic or ordinary foam materials for fixation and protection, such as holding the tool with injection-molded plastic slots or simply wrapping it with single-density foam.

[0003] However, rigid plastic materials are highly rigid, and if subjected to vibration or impact during transportation or handling, especially for small-diameter, fragile tools, the machining parts are easily broken or damaged, seriously affecting the tool's lifespan and machining quality. On the other hand, simple foam wrapping cannot achieve precise positioning and complete protection of the tool, making it easy for the tool to shake and collide inside the packaging, thus offering limited protection.

[0004] Therefore, this application studies a knife packaging box that can more comprehensively protect the knife and improve its service life and processing quality. Utility Model Content

[0005] In order to provide more comprehensive protection for cutting tools and improve their service life and machining quality, this application provides a cutting tool packaging box.

[0006] This application provides a knife packaging box, which adopts the following technical solution: A knife packaging box includes an upper cover and a lower cover that fit together; the upper cover has an upper support and an upper protective member inside, and the lower cover has a lower support and a lower protective member inside; when the packaging box is closed, the upper support and the lower support work together to position and hold the handle of the knife, and the upper protective member and the lower protective member work together to wrap the machining part of the knife.

[0007] By adopting the above technical solution, which uses an upper support and a lower support to jointly position and clamp the tool shank, and an upper protective component and a lower protective component to jointly wrap the tool machining part, the tool can be fixed while the machining part is protected. This provides more comprehensive protection for the tool, reduces the risk of damage, and improves the tool's service life and machining quality.

[0008] Optionally, the upper support member is an upper support foam and has a first groove; the lower support member is a lower support foam and has a second groove; when the packaging box is closed, the first groove and the second groove cooperate to clamp and fix the knife.

[0009] By adopting the above technical solution, a flexible and precise locking position is provided for the knife shank, which effectively solves the problem of the knife shaking and colliding inside the packaging, and achieves reliable positioning and fixation.

[0010] Optionally, the lower support member extends along its length and has a clearance groove.

[0011] By adopting the above technical solution, the operator can easily insert their fingers or tools to pry up the knife, which solves the problem that small-diameter knives are difficult to remove from the tight groove due to their small size, thus improving the convenience and safety of retrieval.

[0012] Optionally, the upper protective component is an upper protective foam, and the lower protective component is a lower protective foam; when the packaging box is closed, the upper protective foam and the lower protective foam come into contact with each other and are squeezed and deformed to wrap the processing part of the tool.

[0013] By adopting the above technical solution, using soft foam as a protective component and compressing and deforming it when closed, it can closely fit and fully wrap the fragile tool processing part, effectively absorbing and buffering external impact energy, and solving the problem of vibration being directly transmitted to the tool and causing breakage.

[0014] Optionally, a pad strip is also provided inside the lower cover. The pad strip is located on the side of the lower support member away from the lower protective member and is used to abut the end of the cutter.

[0015] By adopting the above technical solution, a stable support reference is provided for the end of the tool, which enables more comprehensive protection of the tool.

[0016] Optionally, a folding plate is also included, through which one side of the upper cover and the lower cover are connected.

[0017] By adopting the above technical solution, the upper and lower lids of the packaging box can be placed flat on the table after opening, which solves the risk of the packaging box becoming unstable and tipping over and dropping the knives due to the upper lid being suspended in the air.

[0018] Optionally, a locking hole is provided on one side of the upper cover, and a convex circle is provided on one side of the lower cover to cooperate with the locking hole; when the packaging box is closed, the locking hole and the convex circle are engaged with each other.

[0019] By adopting the above technical solution, reliable closure of the packaging box is achieved, preventing accidental opening during transportation. At the same time, the structure has a small separation force, which makes the opening action smooth and solves the problem of the blade falling off due to sudden opening.

[0020] Optionally, the outer wall of the upper cover and the outer wall of the lower cover are provided with mutually cooperating stacking positioning structures. When multiple packaging boxes are stacked, the stacking positioning structure of the upper cover and the stacking positioning structure of the lower cover are mutually engaged and positioned.

[0021] By adopting the above technical solution, multiple packaging boxes can be interlocked and positioned during stacking and transportation, effectively preventing the risk of stacking slippage and tipping, and improving the stability and efficiency of sorting, packing and transportation.

[0022] Optionally, the sidewall edges of the upper cover and / or the lower cover are provided with protrusions.

[0023] By adopting the above technical solutions, the action of opening the packaging box becomes less strenuous and more controllable.

[0024] Optionally, it may also include a label disposed on the upper cover or the lower cover, and a seal connecting the upper cover and the lower cover, the seal having a breakable structure.

[0025] In summary, this application includes the following beneficial technical effects: 1. The structure adopts an upper support and a lower support to jointly position and clamp the tool shank, and an upper protective part and a lower protective part to jointly wrap the tool machining part. This structure can fix the tool and protect the machining part at the same time, which can more comprehensively protect the tool, reduce the risk of damage, and improve the tool's service life and machining quality. 2. The upper and lower support foams provide flexible and precise positioning for the knife handle, effectively solving the problem of the knife shaking and colliding inside the packaging, and achieving reliable positioning and fixation; 3. The upper and lower protective foams use soft foam as protective components, which are compressed and deformed when closed, so as to closely fit and fully wrap the fragile tool processing parts, effectively absorbing and buffering external impact energy, and solving the problem of vibration being directly transmitted to the tool and causing breakage.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a knife packaging box. (Refer to...) Figure 1 The tool packaging box includes an upper cover 01 and a lower cover 02 that fit together. When closed, the side wall of the upper cover 01 covers the side wall of the lower cover 02, that is, the inner side wall of the upper cover 01 is in contact with the outer side wall of the lower cover 02. The upper cover 01 is provided with an upper support member 11 and an upper protective member 10, which are attached to one side of the upper support member 11 and the upper protective member 10. The lower cover 02 is provided with a lower support member 13 and a lower protective member 12, which are attached to one side of the lower support member 13 and the lower protective member 12. When the packaging box is closed, the upper support member 11 and the lower support member 13 work together to position and hold the shank of the tool 15, and the upper protective member 10 and the lower protective member 12 work together to cover the machining part of the tool 15. The upper support 11 and the lower support 13 jointly position and clamp the shank of the tool 15, and the upper protective member 10 and the lower protective member 12 jointly wrap the machining part of the tool 15. This structure allows the tool 15 to be fixed while protecting the machining part, thus providing more comprehensive protection for the tool 15, reducing the risk of damage, and improving the service life and machining quality of the tool 15.

[0031] Reference Figure 2In some embodiments, the upper support member 11 is an upper support foam, and has a plurality of first grooves 17 spaced apart along its length, each first groove 17 extending along the width direction of the upper support foam; the lower support member 13 is a lower support foam, and has a plurality of second grooves 16 spaced apart along its length, each second groove 16 extending along the width direction of the upper support foam; when the packaging box is closed, the first grooves 17 and the second grooves 16 cooperate to clamp and fix the knife 15. This provides a flexible and precise locking position for the handle of the knife 15, effectively solving the problem of the knife 15 shaking and colliding inside the packaging.

[0032] Reference Figure 3 In some embodiments, the lower support 13 extends along its length and has a relief groove 18. The relief groove 18 penetrates vertically through the middle section of the second groove 16 and is located on the side away from the lower protective member 12. This allows the operator to easily insert their fingers or tools to pry up the knife 15, solving the problem that the small-diameter knife 15 is difficult to remove from the tight groove due to its small size, thus improving the convenience and safety of retrieval.

[0033] Reference Figure 1 and Figure 3 In some embodiments, the upper protective element 10 is an upper protective foam with a density lower than that of the upper supporting foam; the lower protective element 12 is a lower protective foam with a density lower than that of the lower supporting foam, making it softer and better protecting the machining part of the tool 15. When the packaging box is closed, the upper and lower protective foams come into contact with each other and are compressed and deformed, wrapping the machining part of the tool 15. By tightly wrapping the tool 15 with foams of different densities, the positioning, fixing, wrapping and protection of the tool 15 are achieved respectively. When the entire packaging box is subjected to impact and vibration, most of the kinetic energy is absorbed by the internal pore structure and elastic deformation of the foam. The remaining small portion of kinetic energy is conducted to the tool 15 and then reflected back to the foam, and is finally absorbed by the elastic deformation of the foam. This greatly reduces the probability of damage to the tool 15.

[0034] In some embodiments, a pad strip 14 is also provided inside the lower cover 02. The pad strip 14 is located on the side of the lower support member 13 away from the lower protective member 12 and is used to abut the end of the cutter 15. The pad strip 14 is a foam pad strip 14 with the same density as the lower support member 13, both being relatively high and compact. When the cutter 15 is placed, its end abuts against the pad strip 14, which can limit and support the cutter 15, allowing the cutter 15 to be placed more stably.

[0035] In some embodiments, a folding plate 03 is also included, and one side of the upper cover 01 and the lower cover 02 are connected by the folding plate 03. The folding plate 03 is folded and connected to both the upper cover 01 and the lower cover 02. When the packaging box is opened, the folding plate 03 can be in a horizontal state, so that the upper cover 01 can also be placed horizontally, so that the packaging box can be placed stably after opening, and the weight of the upper cover 01 can prevent the packaging box from tipping over.

[0036] Reference Figure 3 and Figure 4 In some embodiments, a locking hole 06 is provided on one side of the upper cover 01, and another locking hole 06 is provided on the side opposite to the folding plate 03. One or more locking holes 06 are spaced apart along the length of the upper cover 01, specifically three. A raised circle 05 is provided on one side of the lower cover 02 to cooperate with the locking hole 06. When the packaging box is closed, the locking hole 06 and the raised circle 05 are engaged with each other. This allows for easy fixing of the upper cover 01 and the lower cover 02, and also allows for easy opening under force.

[0037] Reference Figure 4 In some embodiments, the sidewall edges of the upper cover 01 and / or the lower cover 02 are provided with protrusions 07. In this embodiment, both the upper cover 01 and the lower cover 02 are provided with protrusions 07, making it convenient to open the packaging box.

[0038] Reference Figure 4 and Figure 5 In some embodiments, the outer walls of the upper cover 01 and the lower cover 02 are provided with mutually cooperating stacking positioning structures. When multiple packaging boxes are stacked, the stacking positioning structures of the upper cover 01 and the lower cover 02 are interlocked and positioned. The stacking positioning structure of the upper cover 01 consists of several snap-fit ​​protrusions 04 on the outer wall, which are "L"-shaped or "I"-shaped. The stacking positioning structure of the lower cover 02 consists of positioning protrusions 04 on the outer wall. The positioning protrusions 04 are arranged around the bottom surface of the lower cover 02. When the packaging boxes are stacked, the snap-fit ​​protrusions 04 and the positioning protrusions 04 interlock and restrict the movement of adjacent packaging boxes, making the stacking more stable. Multiple boxes can be bundled with a single rubber band, which is convenient for sorting, packing, and transportation.

[0039] In some embodiments, the package also includes a label 08 disposed on the upper cover 01 or the lower cover 02, and a seal 09 connecting the upper cover 01 and the lower cover 02, the seal 09 having a breakable structure. In this embodiment, the label 08 is disposed on the upper cover 01, and the label 08 is printed with information such as the manufacturer's logo, CNC tool 15 parameters, and barcode, used to identify the specific model of the tool 15 inside the packaging. The breakable structure consists of spaced dotted holes, allowing the seal 09 to be easily opened through the dotted holes. The seal 09 effectively prevents the protective box from being opened during transportation, and when the packaging box is opened, the seal 09 breaks, ensuring that the packaging of the tool 15 has not been opened before sale, and confirming that the tool 15 has not been used in the event of a return.

[0040] The implementation principle of a tool packaging box in this application embodiment is as follows: the upper support member 11 and the lower support member 13 jointly position and clamp the handle of the tool 15, and the upper protective member 10 and the lower protective member 12 jointly wrap the processing part of the tool 15. This structure can fix the tool 15 and protect the processing part at the same time, which can more comprehensively protect the tool 15, reduce the risk of damage, and improve the service life and processing quality of the tool 15.
