Description

Technical Field

[0001] This utility model relates to the field of product packaging technology, specifically a protective structure to prevent collisions with irregularly shaped products. Background Technology

[0002] In modern manufacturing, die castings are widely used in automotive parts, consumer electronics housings and other fields due to their advantages such as high dimensional accuracy, good surface finish, uniform wall thickness and ability to form complex structures. However, due to the complex structure of die castings and their relatively brittle material, they are easily damaged by collisions during handling, storage and transportation, resulting in surface indentations, scratches, deformation, burrs or even breakage, which affects the product's appearance quality, assembly performance and structural strength.

[0003] Currently, die-cast products are often packaged and transported using materials such as pearl cotton (EPE), bubble bags, plastic pallets, or corrugated cardboard dividers. However, during use, they are often in a loose or random stacked state without any positional restrictions. Under transportation vibration or impact, relative displacement can easily occur, leading to collisions between products and causing product damage. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide a protective structure to prevent collisions of irregularly shaped products. By setting up protective sleeves and connecting components, the placement position of the products can be limited, effectively preventing collisions between products, ensuring the surface quality of the products, and forming a snap-lock structure between the protective sleeves to prevent separation, misalignment or disintegration during transportation, thereby improving the overall structural strength and impact resistance of the packaging.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective structure for preventing collisions with irregularly shaped products, comprising: a protective structure consisting of two protective sleeves for stacking and placing inside a cardboard box as filler; a first placement groove, with multiple first placement grooves on the top of the two protective sleeves and multiple second placement grooves on the bottom of the two protective sleeves; a product body disposed inside the protective sleeves; and a connecting component disposed between the two protective sleeves for connecting them, the connecting component comprising: a fixing groove, a fixing plate, a limiting groove, a slot, and a limiting plate, with multiple fixing grooves on both sides of the protective sleeves, a fixing plate disposed within the fixing grooves, two limiting grooves on one side of the fixing plate, and a slot on the inner wall of the protective sleeve, with a limiting plate connected within the slot.

[0006] Furthermore, multiple first placement slots and second placement slots are evenly arranged and distributed, and the dimensions of the first placement slots and second placement slots are adapted to the cross-sectional dimensions of the product body.

[0007] Furthermore, the fixing grooves on the two protective sleeves are positioned correspondingly.

[0008] Furthermore, the fixing plate is configured in a C-shape, and the thickness of the fixing plate is adapted to the width of the fixing groove.

[0009] Furthermore, the slot corresponds to the fixed slot, and the thickness of the limiting plate is adapted to the size of the limiting slot.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] By using protective sleeves and connecting components, the placement of products can be restricted, effectively preventing collisions between products and ensuring product surface quality. Secondly, the protective sleeves form a snap-locking structure to prevent separation, misalignment, or disintegration during transportation, improving the overall structural strength and impact resistance of the packaging. Furthermore, the entire structure can be completed with simple operations such as plugging, folding, and embedding, requiring no tools and allowing for quick assembly, making it suitable for assembly line operations. At the same time, the structure is reversible, facilitating disassembly and recycling later, enhancing the convenience and efficiency of packaging operations. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] This application provides a protective structure to prevent collisions with irregularly shaped products, thus solving the problem that existing die-cast products are prone to collisions during transportation.

[0021] By setting up the protective sleeve 1 and the connecting components, the placement position of the product can be limited, effectively preventing the products from colliding with each other and ensuring the surface quality of the product. In addition, the protective sleeve 1 forms a snap-lock structure to prevent separation, misalignment or disintegration during transportation, thereby improving the overall structural strength and impact resistance of the packaging.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1 , Figure 2 and Figure 3 As shown, a protective structure for preventing collisions of irregularly shaped products includes: a protective structure consisting of two protective sleeves 1, used for stacking and placing inside a carton as filler; a first placement groove 101, with multiple first placement grooves 101 on the top of the two protective sleeves 1 and multiple second placement grooves 102 on the bottom of the two protective sleeves 1; a product body 3, disposed inside the protective sleeves 1; and a connecting component disposed between the two protective sleeves 1 for connecting the two protective sleeves 1. The connecting component includes: a fixing groove 2, a fixing plate 201, a limiting groove 202, a slot 203, and a limiting plate 204. Multiple fixing grooves 2 are provided on both sides of the protective sleeves 1, and a fixing plate 201 is provided in the fixing groove 2. Two limiting grooves 202 are provided on one side of the fixing plate 201. A slot 203 is provided on the inner wall of the protective sleeve 1, and a limiting plate 204 is connected in the slot 203. The protective sleeves 1, the fixing plate 201, and the limiting plate 204 are all corrugated cardboard.

[0024] When in use, select an appropriate number of protective sleeves 1 to stack according to the height of the product body 3 to be placed. If two protective sleeves 1 are stacked, the multiple fixing slots 2 on the two protective sleeves 1 are in corresponding positions, and multiple fixing plates 201 can be inserted into the fixing slots 2 on the two protective sleeves 1 in sequence. Through the multiple fixing slots 2 and the C-shaped fixing plates 201, the two protective sleeves 1 can be locked together to prevent the two protective sleeves 1 from separating during transportation.

[0025] Then, after the fixing plate 201 is inserted, since the limiting plate 204 is made of corrugated cardboard, one end of which is connected to the protective sleeve 1 and can be folded or rotated, the limiting plate 204 can be snapped out from the slot 203. Then the limiting plate 204 is inserted into the slot 203 on the fixing plate 201. At this time, the position of the fixing plate 201 is limited by the limiting plate 204 and the slot 203. Since the fixing plate 201 and the limiting plate 204 are perpendicular to each other, and the fixing plate 201 and the cardboard where the fixing slot 2 is located are perpendicular to each other, the three can be locked together and fixed to prevent loosening or falling off during handling or transportation. The connection of the two protective sleeves 1 is completed. Then the connected protective sleeves 1 can be placed in the carton to serve as a filling and protective structure. Then the product body 3 can be inserted into the first placement slot 101 and through the second placement slot 102 to complete the loading of the product body 3.

[0026] Reference Figure 3 As shown, multiple first placement slots 101 and second placement slots 102 are evenly arranged and distributed. The dimensions of the first placement slots 101 and second placement slots 102 are adapted to the cross-sectional dimensions of the product body 3, so that the first placement slots 101 and second placement slots 102 can limit the product body 3 and prevent the product body 3 from colliding with each other during transportation, which would cause damage to the product body 3.

[0027] Reference Figure 6 As shown, the fixing grooves 2 on the two protective sleeves 1 are positioned correspondingly, so that the fixing plate 201 can be inserted into the two fixing grooves 2 to connect the two protective sleeves 1.

[0028] Reference Figure 5 and Figure 6 As shown, the fixing plate 201 is C-shaped, and the thickness of the fixing plate 201 is adapted to the width of the fixing groove 2. This allows the fixing plate 201 to limit the cardboard of the two protective sleeves 1 in contact after it is inserted into the fixing groove 2. At the same time, the thickness of the fixing plate 201 and the width of the fixing groove 2 are adapted to increase the friction between the fixing plate 201 and the protective sleeve 1, thus preventing the fixing plate 201 from falling off.

[0029] Reference Figure 6 The slot 203 corresponds to the fixed slot 2. The thickness of the limiting plate 204 is adapted to the size of the limiting slot 202, so that when the limiting plate 204 is folded to be perpendicular to the inner wall of the protective sleeve 1, the limiting plate 204 corresponds to the position of the slot 203. After the limiting plate 204 is inserted into the slot 203, it can fit tightly against the inner wall of the slot 203, increasing the friction between the two, preventing loosening, and improving stability.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
