Description

Technical Field

[0001] This invention relates to the field of television packaging technology, specifically to a segmented assembly mechanism and a protective packaging box for televisions containing the mechanism. Background Technology

[0002] With the rapid development of the home appliance logistics industry, the transportation safety and packaging costs of precision large-screen products such as televisions have become key concerns in the industry.

[0003] Traditional TV packaging mainly uses disposable corrugated cardboard boxes with foam fillers. This model has the following shortcomings: First, the large amount of waste generated by disposable packaging not only wastes resources but also does not conform to the trend of green and low-carbon environmental protection. Second, it is difficult to completely avoid damage to the internal screen during long-distance transportation and multiple transfers. Third, when adapting to different sizes of TVs, some existing recyclable packaging devices often require manual adjustment of the position of the internal cushioning components. The operation process is complicated, and the clamping force depends entirely on manual experience, which can easily lead to problems such as clamping too loosely, causing internal shaking, or clamping too tightly, causing deformation of the body structure. Summary of the Invention

[0004] In order to overcome the above-mentioned technical problems, the present invention aims to provide a segmented assembly mechanism and a television protective packaging box containing the mechanism, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A segmented assembly mechanism includes a TV box, further comprising: a base module, a segmented packaging module, and a strap module. The base module, segmented packaging module, and strap module cooperate to sequentially achieve adaptive clamping and limiting of the bottom of the TV box and secure wrapping of the TV box's outer perimeter under a single power drive of pulling the strap module. The strap module is linked to the base module to convert the pulling force into rotational torque of internal components of the base module to drive the clamping action. The base module is equipped with a self-locking component to lock the power transmission path of the base module when the clamping force reaches a preset value, and to guide subsequent pulling force to the segmented packaging module to perform the wrapping action.

[0006] Preferably, the base module includes a base plate, with end pieces fixedly connected to both ends of the base plate. The base plate is provided with positive and negative threaded rods. The end piece is provided with a first shaft and a second shaft. The first shaft and the second shaft are rotatably connected inside the end piece and are connected by a synchronous belt. The first shaft is fixedly connected to the positive and negative threaded rods.

[0007] Preferably, the second shaft is fixedly connected to a front shaft, the front shaft is rotatably connected to the base plate, and a strapping tube is fixedly connected to the front shaft.

[0008] Preferably, the positive and negative threaded rods are connected to two lower pads via a nut pair. The two lower pads are slidably connected to the base plate via a sliding groove. The lower pads are L-shaped and are used to contact the bottom edge of the TV box. When the positive and negative threaded rods rotate, they drive the two lower pads to move towards each other to perform clamping.

[0009] Preferably, the self-locking assembly includes a pressing member slidably connected within the lower pad, a spring being provided between the pressing member and the lower pad, and an adjusting member being rotatably connected to the bottom of the pressing member, the adjusting member being used to trigger physical locking based on the retraction displacement of the pressing member.

[0010] Preferably, the adjusting component includes an upper shaft, a middle shaft, and a lower rod, which are fixedly connected by a bracket plate. The upper shaft is rotatably connected to the pressing component, and the middle shaft is rotatably connected to the lower pad.

[0011] Preferably, the base plate is provided with a toothed plate corresponding to the position of the lower rod, and the bottom of the lower rod is provided with protruding teeth. The lower rod is used to make its bottom protruding teeth mesh with the toothed plate when the adjusting member rotates around the central shaft, thereby limiting the displacement of the lower pad block.

[0012] Preferably, the back of the base plate is hinged to a back frame plate, and the segmented packaging module includes a packaging plate fixedly connected to the back frame plate.

[0013] Preferably, the segmented packaging module further includes strips one, strip two and strip three connected sequentially to the packaging plate one by creases, for flexible bending to cover the outer peripheral surface of the TV box.

[0014] Preferably, the packaging board one, strip one, strip two and strip three are all composed of an outer layer board and an inner layer board, wherein the outer layer board is a waterproof soft pack and the inner layer board is made of EVA material, which is used to directly contact and protect the TV box.

[0015] Preferably, the strapping module includes an upper strap body, a lower strap body, and a locking buckle. The upper strap body is sewn onto the segmented packaging module, and one end of the lower strap body is fixed and wrapped around the strapping tube. The upper strap body and the lower strap body are connected by the locking buckle. The locking buckle is used to maintain the overall tightness by inserting a locking rod into the hole of the lower strap body after packaging is completed.

[0016] A protective packaging box for televisions, comprising the aforementioned segmented assembly mechanism.

[0017] Compared with the prior art, the beneficial effects of the present invention are: The device adopts a segmented combination and hinged structure, which can not only accommodate the transportation of products of various sizes, but also can be folded to a high degree when unloaded. This design significantly reduces the space occupied in reverse logistics, improves the turnover efficiency of packaging materials, and has significant economic and environmental benefits. The device achieves a "pull and engage" linkage effect through the mechanical transmission design of the belt module and the base module. The operator can drive the lower pads on both sides to perform a centripetal clamping action by pulling the lower belt body with a single power input. This is achieved through the transmission chain of the front axle, synchronous belt and positive and negative threaded rods, which greatly simplifies the packaging process and improves work efficiency. By utilizing the coaxial reverse thread characteristics of the positive and negative threaded rods, it is ensured that the two lower pads on the left and right always maintain equal distance and synchronous movement. This design can not only automatically adapt to TV boxes of various widths, but also ensure that the center of gravity of the TV on the base plate is always centered, effectively improving the physical stability during transportation. The device is equipped with an inductive locking mechanism consisting of a pressure-sensitive component, an adjusting component, and a toothed plate. When the clamping force reaches the preset stability threshold, the lower pad is pressed, triggering the adjusting component to rotate and physically engage with the toothed plate, forcibly cutting off the power transmission path of the lead screw. This mechanism effectively solves the problem of excessive squeezing caused by human error, ensuring secure positioning while protecting the structural safety of the TV box. After the bottom pad is physically locked, the subsequent tension of the pull rope will automatically be converted into the binding force of the upper belt on the segmented packaging module, so that the inner layer board with EVA material is tightly attached to the surface of the TV. This combination of rigid limiting and flexible covering greatly enhances the shock absorption performance of the overall mechanism. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] One embodiment provided by the present invention: refer to Figure 1 and Figure 2 A segmented assembly mechanism includes a TV box 05, which further includes: The base module 01, segmented packaging module 02, and strap module 03 work together to protect the TV box 05 during transportation and can be folded after use. The base module 01 includes a base plate 11, with end pieces 12 fixedly connected to both ends of the base plate 11. The base plate 11 is provided with forward and reverse threaded rods 13. The end piece 12 contains a first shaft 14 and a second shaft 15. The end piece 12 has grooves corresponding to the first shaft 14 and the second shaft 15. The first shaft 14 and the second shaft 15 are rotatably connected within the grooves. A synchronous belt connects the first shaft 14 and the second shaft 15. The first shaft 14 is fixedly connected to the forward and reverse threaded rods 13. The second shaft 15 is fixedly connected to a front shaft 16, which is rotatably connected within the base plate 11. A binding tube is fixedly connected to the front shaft 16. The base plate 11 has a groove corresponding to the binding tube.

[0022] The positive and negative threaded rods 13 are connected to a lower pad 17 via a nut pair. The lower pad 17 is slidably connected to the base plate 11 via a sliding groove. The lower pad 17 is L-shaped and is used to contact the bottom edge of the TV box 05. A pressing member 18 is slidably connected inside the lower pad 17. A spring is provided between the pressing member 18 and the lower pad 17. An adjusting member 19 is rotatably connected to the bottom of the pressing member 18.

[0023] The adjusting component 19 includes an upper shaft 191, a middle shaft 192, and a lower rod 193. The upper shaft 191, the middle shaft 192, and the lower rod 193 are fixedly connected by a bracket plate. The upper shaft 191 is rotatably connected to the pressure member 18, and the middle shaft 192 is rotatably connected to the lower pad block 17. The lower rod 193 has a protruding tooth at its bottom. The base plate 11 has a toothed plate 110 corresponding to the lower rod 193. The toothed plate 110 and the protruding tooth at the bottom of the lower rod 193 mesh.

[0024] The back frame plate 111 is hinged to the back of the base plate 11.

[0025] It should be noted that the outer layer 211 is a PVC-coated nylon waterproof soft padding with an IPX5 waterproof rating.

[0026] refer to Figure 3 The segmented packaging module 02 includes a packaging plate 21, on which a strip 22 is fixedly connected. A strip 23 is connected to the strip 22, and a strip 24 is connected to the strip 23. The strip 22 and the strip 23 are connected by creases, and the strip 23 and the strip 24 are also connected by creases. The packaging plate 21 is fixedly connected to the back frame plate 111. The packaging plate 21 is composed of an outer plate 211 and an inner plate 212. The inner plate 212 is used to contact the TV box 05.

[0027] Packaging board 1 21, board strip 1 22, board strip 2 23 and board strip 3 24 all adopt the design of packaging board 1 21. They are all composed of an outer layer board 211 and an inner layer board 212. The outer layer board 211 is a waterproof soft pack, and the inner layer board 212 is made of EVA material.

[0028] The strapping module 03 includes an upper strap body 31, a lower strap body 32, and a locking buckle 33. The upper strap body 31 is sewn onto packaging board 1 21, strip 1 22, strip 23, and strip 3 24. The upper strap body 31 and the lower strap body 32 are connected by the locking buckle 33. One end of the lower strap body 32 is wrapped around the strapping tube and is fixedly connected to the strapping tube.

[0029] Working principle: Before packaging the TV box 05, the two lower pads 17 on the left and right are manually moved to their extreme positions at both ends of the base plate 11 to leave sufficient space for placement. Then, the TV box 05 is placed vertically directly above the base plate 11. The segmented packaging module 02 is moved so that packaging plate 21, strip 22, strip 23, and strip 24 sequentially adhere to the outer surface of the TV box 05, forming a preliminary enclosure. Next, the upper strap 31 and lower strap 32 are initially connected using the locking fastener 33. At this time, the locking fastener 33 is kept in an unlocked state, allowing the lower strap 32 to slide freely.

[0030] The operator pulls the free end of the lower belt 32, causing the binding cylinder wrapped around the front axle 16 to rotate. This rotational torque is precisely transmitted to the positive and negative threaded rods 13 via a transmission chain consisting of the front axle 16, shaft 15, synchronous belt, and shaft 14. Due to the rotation of the positive and negative threaded rods 13, the two lower pads 17, originally located at their extreme positions, are driven by the nut pair to move towards each other along the sliding groove of the base plate 11. During this process, the lower pads 17 gradually move towards the bottom sides of the TV box 05 using their L-shaped structure, achieving automatic centering and adaptive clamping for TV boxes 05 of different widths.

[0031] As the clamping action deepens, when the lower pad 17 contacts and presses against the side wall of the TV box 05, the internally nested pressing member 18 is compressed and retracts into the groove of the lower pad 17, causing the spring between the pressing member 18 and the lower pad 17 to store and contract. At this time, the displacement of the pressing member 18 causes the adjusting member 19 to rotate clockwise around its central axis 192. When the clamping force reaches the preset stable state, the pressing member 18 is fully retracted. At this time, the lower rod 193 at the end of the adjusting member 19 strongly engages with the toothed plate 110 on the base plate 11 through the protruding teeth at its bottom. This mechanism produces a key technical effect: once the engagement is completed, the transmission chain at the bottom is physically locked. Even if the pulling force on the lower belt 32 is further increased, the forward and reverse threaded rod 13 cannot continue to rotate, thereby effectively preventing the TV box 05 structure from deforming due to excessive clamping.

[0032] After the bottom pad 17 completes its limiting and locking, the tension generated by continuing to pull the lower belt 32 will all react on the upper belt 31. At this time, the upper belt 31 quickly tightens on the surface of the segmented packaging module 02. Due to the flexible cushioning properties of the inner layer plate 212 (EVA material), the tightening force can make the packaging plate and the TV box 05 fit tightly together. When the overall mechanism reaches the required packaging tightness, the operator inserts the locking rod in the locking buckle 33 into the corresponding hole in the lower belt 32 to complete the final position locking.

[0033] After packaging is complete, the entire segmented assembly can be unfolded into Figure 5 As shown in the image, this state facilitates recycling.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
