Technical Field

[0001] This utility model relates to the field of pulp molding packaging technology, and in particular to a pulp molding packaging structure. Background Technology

[0002] In today's packaging industry, with increasing environmental awareness and increasingly stringent requirements for product protection, innovation in packaging materials and structures has become a key driver of industry development. Pulp molding technology has emerged as a result, using waste paper as its main raw material and employing molding machines with specialized molds to create a wide variety of paper packaging products. This technology, with its numerous advantages such as a wide availability of raw materials, recyclability, and environmental friendliness, has rapidly gained a foothold in the packaging industry. Besides its widespread use in the production of lunch boxes and tableware, it is also a highly favored material in the field of industrial cushioning packaging.

[0003] During transportation or handling, multiple molded pulp packaging components often work together to protect the product from multiple angles to ensure product safety. However, existing modular molded pulp packaging designs lack overall consideration. Packaging components arranged front-to-back or side-to-side are typically simply attached without reliable connection or locking mechanisms. This makes them highly susceptible to detachment and scattering during bumpy and vibrating logistics transport, leaving the product instantly unprotected and significantly increasing the risk of damage, resulting in unnecessary economic losses for businesses.

[0028] Example

[0029] Reference Figures 1-4 As an embodiment of the present invention, a pulp mold packaging structure is provided, including: a support unit 100 and a locking unit 200.

[0030] The support unit 100 includes a top housing 101 and a bottom housing 102. A plurality of scissor structures 103 are provided between the top housing 101 and the bottom housing 102. Each scissor structure 103 includes a pivot 104, a first connecting rod 105 and a second connecting rod 106. A connecting hole is provided through the middle of the first connecting rod 105 and the second connecting rod 106. The pivot 104 is located inside the connecting hole. The first connecting rod 105 and the second connecting rod 106 are rotatably connected through the pivot 104. The ends of the first connecting rod 105 and the second connecting rod 106 in two adjacent scissor structures are rotatably connected.

[0031] A limiting groove 107 is provided on the bottom housing 102, and a sliding groove 108 is provided on the bottom housing 102. The sliding groove 108 communicates with the limiting groove 107. The ends of the first connecting rod 105 and the second connecting rod 106 in the scissor structure 103 are rotatably connected to sliders 211. The sliders 211 pass through the sliding groove 108 and extend into the interior of the limiting groove 107. The bottom end of the sliders 211 is fixedly connected to a limiting block 212. The limiting block 212 is located inside the limiting groove 107, and the limiting block 212 is slidably connected to the limiting groove 107.

[0032] A baffle 213 is fixedly connected to the slider 211, and the bottom end of the baffle 213 abuts against the top end of the bottom housing 102.

[0033] The locking unit 200 includes a ratchet rack 201.

[0034] The locking unit 200 further includes a fixing block 202 and a frame 203. A connecting shaft 204 is fixedly connected to both the fixing block 202 and the frame 203. The fixing block 202 is rotatably connected to the top first connecting rod 105 via the connecting shaft 204, and the frame 203 is rotatably connected to the top second connecting rod 106 via the connecting shaft 204. A ratchet rack 201 is fixedly connected to the fixing block 202 and passes through the frame 203. A connection is established between the ratchet rack 201 and the frame 203. The frame 203 is slidably connected to a connecting member 205, which is fixedly connected to the top of the frame 203. A limiting tooth 206 passes through the inside of the connecting member 205. A top rod 207 is fixedly connected to the top of the limiting tooth 206. A bracket 208 is fixedly connected to the connecting member 205. The top end of the top rod 207 passes through the bracket 208. The top rod 207 and the bracket 208 are slidably connected. A spring 214 is sleeved on the outer surface of the top rod 207 between the bracket 208 and the limiting tooth 206.

[0035] A pull ring 215 is fixedly connected to the top end of the top rod 207, and the pull ring 215 is located above the bracket 208.

[0036] The top housing 101 has a notch 209 and a receiving groove 210, and the ratchet 201 is located inside the receiving groove 210.

[0037] When using this pulp molding packaging structure to package items, first place the item in a suitable position above the bottom housing 102, then place the top housing 101 on top of the item. At this time, the scissor structure 103 is in the closed state and can easily pass through the notch 209 into the receiving groove 210. Then press the ratchet 201 to make it move slowly towards the top housing 101. The ratchet 201 slides smoothly within the frame 203. During this process, the scissor structure 103 located between the top housing 101 and the bottom housing 102 are linked. The first link 105 and the second link 106 rotate flexibly around their respective pivots 104. The ends of the links between adjacent scissor structures 103 cooperate to adjust the angle. The slider 211 at the end of the lower scissor structure 103 slides smoothly within the slide groove 108, causing the limiting block 212 to move smoothly within the limiting groove 107. As the scissor mechanism 103 dynamically adjusts, the entire support unit 100 quickly adapts to the shape of the item until the ratchet 201 fits against the bottom of the inner wall of the receiving groove 210, forming a stable support shape to ensure that the item is in a stable and balanced state inside the packaging.

[0038] Due to the pre-compression force of the spring 214, the limiting tooth 206 will tightly engage with the tooth groove of the ratchet 201, achieving precise and reliable locking. Once locking is complete, the entire packaging structure transforms into a tightly connected whole, and the packaging components arranged in opposite directions will no longer easily separate or fall off. The product is securely locked inside the packaging, receiving all-around protection.

[0039] When it is necessary to remove it, the operator only needs to hold the pull ring 215 with one hand and gently pull the pull ring 215 upward. The pull ring 215 drives the push rod 207 to move upward against the elastic force of the spring 214, so that the limiting tooth 206 gradually disengages from the groove of the ratchet 201 and releases the locked state. Then, pull the ratchet 201 upward, so that the top shell 101 is no longer restricted.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
