Description

Technical Field

[0001] This utility model belongs to the technical field of packaging structure, specifically relating to a packaging structure for a model car. Background Technology

[0002] Existing model car packaging structures serve to protect and prevent collisions. They typically consist of a main shell, two side protective plates, and a cover shell. The main shell facilitates the placement of the model car, while the two side protective plates adapt to the shape of the model car's sides to provide protection. The main shell also reinforces and secures the overall connection, preventing loose packaging and poor handling. When packaging a model car, the packer must first place the model car inside the unfolded main shell, then place the two side protective plates against the sides of the main shell, and finally slip the entire car into the cover shell to complete the packaging process. This method involves numerous packaging components, high production costs, complex procedures, low packaging efficiency, and inconsistent quality. Furthermore, the structure inside the cover shell is prone to detaching from the cover shell after assembly due to bumps or collisions, leading to poor handling. Utility Model Content

[0003] The purpose of this utility model is to provide a packaging structure for a model car to address the aforementioned problems.

[0004] This utility model is achieved through the following technical solution: a packaging structure for a model car, including an inner shell for assembling the model car and an outer shell fitted outside the inner shell. The inner shell includes an inner bottom plate, a left vertical plate and a right vertical plate respectively connecting the left and right sides of the inner bottom plate, and a top plate connected to the upper end of the left vertical plate. The inner bottom plate is provided with an installation groove. The upper end of the right vertical plate is provided with a detachable connector for connecting the movable end of the top plate. The outer shell includes an outer bottom plate and a front vertical plate and a rear vertical plate respectively connecting the front and rear sides of the outer bottom plate. The upper end of the front vertical plate is provided with a first connecting plate with an insertion hole. The upper end of the rear vertical plate is provided with a second connecting plate with a hook. The inner surfaces of the front and rear vertical plates are provided with limiting protrusions. When the hook is engaged in the insertion hole, the limiting protrusion extends between the left and right vertical plates.

[0005] Furthermore, the upper surface of the free end of the top plate is provided with an inverted conical groove, and a locking block is provided on the side of the inverted conical groove near the right vertical plate. The connector is adapted to the shape of the inverted conical groove, and the bottom surface of the connector is provided with a locking groove for use with the locking block.

[0006] Furthermore, the inner walls of the front and rear sides of the inverted conical groove are provided with fixing protrusions, and the outer walls of the front and rear sides of the connector are provided with fixing grooves that cooperate with the fixing protrusions.

[0007] Furthermore, the limiting protrusion includes a long protrusion and two vertically arranged short protrusions located on both sides of the long protrusion, and the shape of the gap between the top plate and the front and rear sides of the inner shell is adapted to the shape of the limiting protrusion.

[0008] In use, the top plate of the inner shell is first rotated and folded upwards along the left vertical plate to open the model car. The model car is then placed in the mounting groove of the inner bottom plate, and the top plate is then covered. The free end of the top plate and the right vertical plate are fixedly connected by the connector. At this time, the model car is covered by the inner shell on all sides. The inner shell is then placed into the outer shell, so that the front and rear sides of the model car are covered by the front and rear vertical plates of the outer shell, respectively. The front and rear vertical plates can be fixed relative to each other by hooks inserted into the insertion holes, thus completing the wrap-around packaging of the model car. Compared with the existing packaging structure, the present invention has fewer packaging accessories, relatively reduced production costs, simpler packaging steps, and higher packaging efficiency. By extending the limiting protrusion into the inner shell, the outer shell tightly wraps the inner shell, which can enhance the fixing effect between packaging accessories, ensure packaging quality, and reduce the likelihood of poor packaging.

[0013] The present invention will be further illustrated below with reference to specific examples and accompanying drawings.

[0014] like Figures 1-2As shown, this utility model describes a packaging structure for a model car, including an inner shell 1 for assembling the model car and an outer shell 2 fitted over the inner shell 1. The inner shell 1 includes an inner bottom plate 11, a left vertical plate 12 and a right vertical plate 13 respectively connecting the left and right sides of the inner bottom plate 11, and a top plate 14 connected to the upper end of the left vertical plate 12. The inner bottom plate 11 is provided with a mounting groove 111, and the upper end of the right vertical plate 13 is provided with a detachable connector 131 connecting to the movable end of the top plate 14. The outer shell 2 includes an outer bottom plate 21 and a top plate 13 respectively connecting the left and right sides of the model car. The front vertical plate 22 and the rear vertical plate 23 are connected to the front and rear sides of the outer base plate 21. The upper end of the front vertical plate 22 is provided with a first connecting plate 221, and the first connecting plate 221 is provided with an insertion hole 222. The upper end of the rear vertical plate 23 is provided with a second connecting plate 231, and the second connecting plate 231 is provided with a hook 232. The inner surfaces of the front vertical plate 22 and the rear vertical plate 23 are provided with limiting protrusions 24. When the hook 232 is engaged with the insertion hole 222, the limiting protrusion 24 extends between the left vertical plate 12 and the right vertical plate 13.

[0015] In use, first, rotate and fold the top plate 14 of the inner shell 1 upwards along the left vertical plate 12 to open it. Place the model car in the mounting groove 111 of the inner bottom plate 11, and then cover it with the top plate 14. Use the connector 131 to fix the free end of the top plate 14 and the right vertical plate 13. At this time, the model car is covered by the inner shell 1 on all sides. Then, put the inner shell 1 into the outer shell 2, so that the front and rear sides of the model car are covered by the front vertical plate 22 and the rear vertical plate 23 of the outer shell 2 respectively. The front vertical plate 22 and the rear vertical plate 23 can be fixed relative to each other by using the hook 232 to snap into the insertion hole 222, thereby completing the wrap-around packaging of the model car. Compared with the existing packaging structure, this utility model has fewer packaging accessories, relatively reduced production costs, simpler packaging steps, and higher packaging efficiency. By using the limiting protrusion 24 to extend into the inner shell 1, the outer shell 2 can tightly wrap the inner shell 1, which can strengthen the fixing effect between packaging accessories, ensure packaging quality, and prevent poor box throwing.

[0016] In this embodiment of the invention, the upper surface of the free end of the top plate 14 is provided with an inverted conical groove 141. A locking block 142 is provided on the side of the inverted conical groove 141 near the right vertical plate 13. The connector 131 is adapted to the shape of the inverted conical groove 141, and the bottom surface of the connector 131 is provided with a locking groove 132 for use with the locking block 142. When the model car is placed into the mounting groove 111 of the inner bottom plate 11, the top plate 14 is first flipped and pressed down to make it parallel to the inner bottom plate 11. Then the connector 131 is flipped so that the connector 131 is inserted into the inverted conical groove 141 on the upper surface of the top plate 14. At the same time, the locking block 142 in the inverted conical groove 141 is inserted into the locking groove 132 on the bottom surface of the connector 131, thereby realizing the fixed connection between the top plate 14 and the right vertical plate 13.

[0017] Since the packaging structure of the model car is usually integrally injection molded from plastic, the connection between the right vertical plate 13 and the connector 131, and between the left vertical plate 12 and the top plate 14, is formed by bending a plastic sheet. This results in a certain elastic recovery stress, which means that the top plate 14 and the connector 131 tilt upwards at a certain angle. This leads to poor connection stability between the top plate 14 and the connector 131. To improve the connection stability, in this embodiment, the inner walls of the inverted conical groove 141 on both the front and rear sides are provided with fixing protrusions 143, and the outer walls of the connector 131 on both the front and rear sides are provided with fixing grooves 133 that cooperate with the fixing protrusions 143. Thus, when the connector 131 is inserted into the inverted conical groove 141, the two fixing protrusions 143 are also inserted into the fixing grooves 133, achieving multi-directional fixing and positioning, thereby improving the connection stability between the top plate 14 and the connector 131.

[0018] In this embodiment of the utility model, the limiting protrusion 24 includes a long protrusion 241 and two vertically arranged short protrusions 242 located on both sides of the long protrusion 241. The shape of the gap between the top plate 14 and the inner bottom plate 11 on the front and rear sides of the inner shell 1 is adapted to the shape of the limiting protrusion 24. The long protrusion 241 and the two short protrusions 242 cooperate to form an "I" shaped limiting structure, so that when the limiting protrusion 24 is inserted into the gap between the inner shell 1 and the inner bottom plate 11 and the left vertical plate 12 and the right vertical plate 13, the limiting angle is greater, which effectively prevents the inner shell 1 from slipping out of the outer shell 2 during bumps and collisions, thus affecting the packaging quality.

[0019] The above embodiments are merely preferred embodiments of the present utility model and are only used to explain the present utility model, not to limit the present utility model. Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
