Description

Technical Field

[0001] This utility model relates to the field of composite film packaging technology, specifically a composite film packaging structure with double-sided compression resistance. Background Technology

[0002] Packaging bags refer to bags used to package various products, making it convenient to transport and store goods during production and distribution. They are widely used in daily life and industrial production. Composite film packaging structure is a type of composite film packaging bag. For example, patent document CN202220267940.7, entitled "A PET Composite Film Packaging Bag with Safety Buckle", shows that existing composite film packaging structures are just individual bag bodies and lack anti-compression structures, which makes food easily deformed by compression when transported using composite film packaging structures.

[0003] A search revealed patent document CN202323182626.2, entitled "A Multi-Layer Composite Food Packaging Film Bag." This patent aims to prevent food from being easily squeezed and deformed during transport by providing multi-directional support to the packaging bag. The easy assembly and disassembly of the first support rod and the snap-fit ​​seat allows the composite film packaging bag to be folded for convenient storage during use. However, when a large amount of food is placed inside the bag, the food will come into contact with the sides of the bag. If squeezed, it still fails to effectively protect the food. Furthermore, this technical solution only provides pressure resistance to the sides through limiting blocks and rotating parts between the fixed seat and the first support rod, resulting in insufficient pressure resistance. Under excessive pressure, the limiting blocks and rotating parts are prone to breakage. Moreover, the stability is weak due to the limitation provided only by the limiting blocks 11. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a composite film packaging structure with double-sided compression resistance, which solves the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a composite film packaging structure with double-sided compression resistance, including a first baffle and a second baffle, wherein the first baffle and the second baffle are respectively adhered to both sides of the composite film packaging bag;

[0006] Mounting rods are provided at both ends of the baffle one near the baffle two. A round rod is provided on the mounting rod, and a mounting plate is sleeved on the outer side of the round rod.

[0007] A guide rod is vertically arranged on the mounting plate. Sliders are slidably sleeved on both the upper and lower sides of the guide rod. A spring is arranged between the two sliders and sleeved on the outside of the guide rod. A vertical insertion rod is arranged at the ends of the two sliders that are far apart from each other and penetrates the mounting plate. A protrusion is provided on the baffle plate, and the insertion rod penetrates the protrusion vertically.

[0008] Reinforcing components are installed on both sides of the slider.

[0009] Preferably, the mounting rod is provided with a groove that fits into the mounting plate.

[0010] Preferably, the second baffle is provided with a U-shaped abutment block, and the two ends of the abutment block are in contact with the sliders on both sides respectively.

[0011] Preferably, the recessed portion of the abutment block is located in the middle of the vertical position.

[0012] Preferably, the reinforcing component includes a slide frame that is laterally slidably connected to the slider, a reinforcing rod that passes through the baffle two on the slide frame, and a spring two that is connected to the slider.

[0013] Preferably, the sliding frame is located on the side of the insert rod away from the composite film packaging bag.

[0014] This invention provides a composite film packaging structure with double-sided compression resistance. Compared with the prior art, it has the following advantages:

[0015] 1. This composite film packaging structure with double-sided compression resistance can resist compression on both sides of the composite film packaging bag by setting baffle one and baffle two on both sides of the composite film packaging bag, so as to avoid damage to the food when there is too much food.

[0016] 2. This composite film packaging structure with double-sided compression resistance, by setting a groove that fits with the mounting plate, does not affect the rotation of the mounting plate, and can contact the mounting plate through the groove when compressed. This means that it is not only supported by the round rod, but also by setting a U-shaped clamping block that can contact the sliders on both sides. Thus, it is not only supported by the insert rod, but also avoids the breakage of the insert rod and round rod compared with the prior art.

[0017] 3. This composite film packaging structure with double-sided compression resistance can reinforce the slider through reinforcement components, thereby improving the stability of the mounting plate. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figures 1-4 This utility model provides the following two technical solutions:

[0025] First implementation: A composite film packaging structure with double-sided compression resistance includes baffle 1 and baffle 2. Baffle 1 and baffle 2 are respectively bonded to both sides of the composite film packaging bag 16. When both sides are compressed, the compression is blocked by baffle 1 and baffle 2, thus avoiding compression of the composite film packaging bag 16.

[0026] To prevent baffle 1 and baffle 2 from moving to opposite sides, mounting rods 3 are provided at both ends of baffle 1 near baffle 2. A round rod 4 is provided on the mounting rod 3, and a mounting plate 5 is sleeved on the outside of the round rod 4. A guide rod 7 is vertically provided on the mounting plate 5. Slider 8 is slidably sleeved on both the upper and lower sides of the guide rod 7. A spring 9 is provided between the two sliders 8 and sleeved on the outside of the guide rod 7. A vertical insertion rod 10 is provided at the opposite ends of the two sliders 8, penetrating the mounting plate 5. A protrusion 11 is provided on baffle 2, and the insertion rod 10 penetrates the protrusion 11 vertically, so that the mounting plate 5 cannot rotate with the help of the round rod 4, thus fixing baffle 1 and baffle 2 together. When folding and storing, the two sliders 8 are moved to opposite sides, so that they move on the guide rod 7, which compresses the spring 9, thereby causing the insertion rod 10 on the slider 8 to move away from the protrusion 11.

[0027] Reinforcing components are provided on both sides of the slider 8.

[0028] The mounting rod 3 is provided with a groove 6 that fits into the mounting plate 5. When the mounting plate 5 rotates via the round rod 4, it also fits into the groove 6, so that it does not affect its rotation. When the mounting plate 5 is needed, the groove 6 can contact the mounting plate 5, so that when it is squeezed, it is supported not only by the round rod 4, but also by the groove 6 contacting the mounting plate 5.

[0029] The baffle 2 is provided with a U-shaped abutment block 12, and the two ends of the abutment block 12 are in contact with the sliders 8 on both sides respectively. The recessed part of the abutment block 12 is located in the middle of the vertical position, so that after the slider 8 is moved to the opposite side, the slider 8 can be placed in the recessed part, so as not to affect its rotation with the mounting plate 5. The slider 8 contacts the abutment block 12, so it can be supported not only by the insertion rod 10, but also by the slider 8 contacting the abutment block 12.

[0030] The reinforcement component includes a sliding frame 13 that is laterally slidably connected to the slider 8. A reinforcement rod 14 is provided on the sliding frame 13 that penetrates the second baffle 2. A second spring 15 is provided on the sliding frame 13 and is connected to the slider 8. When the reinforcement rod 14 penetrates the second baffle 2, the slider 8 cannot move vertically, thereby reinforcing the insertion rod 10.

[0031] The second implementation differs from the first implementation in that the sliding frame 13 is located on the side of the insert rod 10 away from the composite film packaging bag 16, which does not affect the user's ability to pull the sliding frame 13. When it is necessary to fold and store the composite film packaging bag 16, two fingers are inserted into the two sliding frames 13 to pull and compress the second spring 15, which will cause the reinforcing rod 14 to leave the second baffle 2. Then, by moving the sliding frame 13 to the opposite side, the slider 8 can be moved, thereby causing the insert rod 10 to leave the protrusion 11.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] In use, the mounting plate 5 is inserted into the protrusion 11 via the insert rod 10, and the reinforcing rod 14 is inserted into the baffle 2, thus fixing the position between the baffle 1 and the baffle 2. When food is placed into the composite film packaging bag 16, only the baffle 1 and the baffle 2 will be squeezed when both sides are squeezed, and the food will not be squeezed. When squeezed, the slot 6 contacts the mounting plate 5, and the slider 8 contacts the abutment block 12, so that when squeezed, it is not only supported by the round rod 4 and the insert rod 10, thereby improving the service life of this packaging structure and solving the problems existing in the prior art.
