Description

Technical Field

[0001] This utility model patent relates to the field of meteorological equipment technology, specifically to a shockproof protective box for meteorological sounding balloons. Background Technology

[0002] Weather sounding balloons are one of the core pieces of equipment in the field of meteorological observation. By carrying radiosondes into the air, they can collect key meteorological data in real time, such as atmospheric temperature, humidity, air pressure, and wind speed, providing indispensable basic data support for short-term weather forecasting, climate research, and extreme weather warnings. Throughout the entire lifecycle of a weather sounding balloon, from equipment storage and transportation to on-site preparation for field operations, the integrity of its core components (including the balloon itself, the drag chute, connecting ropes, and associated fasteners) directly determines the success rate of the observation mission.

[0003] Currently, the protective devices used for weather balloon components in the meteorological field are mostly "general-purpose box structures". Their operating principle is based on the design of "physical isolation of the outer shell": the outer shell made of metal or high-strength plastic provides basic physical protection for the components such as balloons, parachutes, and ropes stored inside, avoiding collisions and dust from the external environment from directly affecting the components; some boxes are equipped with simple partitions or foam pads inside to achieve preliminary partitioning of the components and prevent direct friction between different components. Summary of the Invention

[0004] To address some or all of the aforementioned technical problems, this application provides a shockproof protective box for weather balloons, which has the technical advantages of fixing and folding the deflated weather balloon for storage, preventing parachute ropes from getting tangled, and orderly folding and clamping the balloon body.

[0005] A shockproof protective case for weather balloons includes: a case body, wherein a rope compartment and a parachute compartment are disposed within the case body; a cover plate, the rear side of which is axially connected to the rear side of the case body; a winding shaft, disposed within the rope compartment, with spirally distributed dividing rods on the side of the winding shaft; and a fastening structure, comprising a connecting shaft, a torsion spring, and a housing, wherein the connecting shaft is fixedly installed in the upper end face of the winding shaft, the torsion spring is sleeved on the outside of the connecting shaft, the housing is sleeved on the outside of the torsion spring, the two ends of the torsion spring are respectively connected to the connecting shaft and the housing, the outer sides of the housing and the winding shaft overlap and abut against each other, and a connecting hook is provided on the outer side of the housing; wherein a through slot is provided between the rope compartment and the parachute compartment.

[0006] By adopting the above technical solution, the interior of the container is divided into a rope compartment and a parachute compartment, which allows for the classified storage of the ropes and parachute components of the weather balloon. Furthermore, the through-slot between the two compartments can create a linkage and adaptation channel between the ropes and parachute. This design meets the requirements for classified and zoned storage without requiring disassembly of the components.

[0007] The winding shaft is fixedly installed inside the rope compartment. The spirally distributed dividing rods on its side can form layered limiting of the rope, guiding the rope to wind in an orderly manner along the spiral trajectory. During operation, the rope can be stored layer by layer along the dividing rods without tangling, knotting or overlapping, effectively avoiding surface wear caused by disorderly stacking of the rope.

[0008] In the fastening structure, the connecting shaft is fixed to the upper end face of the winding shaft. The torsion spring sleeved on the outside can generate a restoring force through elastic deformation. The outer shell of the torsion spring coincides and abuts against the outer side of the winding shaft, which not only protects the torsion spring but also ensures the fit of the structure. The connecting hook on the outer side of the shell can be fastened to the end of the weather balloon rope to achieve a fixed connection between the balloon and the rope.

[0009] During operation, the end of the balloon will not detach from the rope, and the restoring force of the torsion spring can maintain the elastic tension of the fixed stability, reducing the risk of fixation failure.

[0010] The cover is connected to the rear side of the box via a pivot, allowing it to be flipped open and closed around the pivot. In actual operation, the cover opens and closes smoothly without any loosening or jamming, reliably completing the sealing and protection of the box and the access and switching of components. When closed, it can protect the internal components from the influence of the external environment, and when open, it facilitates quick access to rope, parachute and balloon components.

[0011] Optionally, the outer side of the box is wrapped with shock-absorbing sponge, a water seepage hole is provided through the lower end face of the box, reinforcing angle steel is provided at the included angle of the box, and the edges of the rope compartment and the umbrella compartment are chamfered and blunted.

[0012] By adopting the above technical solutions, the shock-absorbing sponge on the outside of the box absorbs the impact through elastic deformation, weakening the external force generated by transportation bumps, collisions or drops, and preventing damage to components such as ropes, umbrellas, and balloons inside the box; the drainage holes on the lower end face can drain water accumulated inside the box (such as rainwater and condensation), preventing rope corrosion and umbrella mildew, and ensuring the durability of the components; the angle steel reinforcement at the corners enhances the deformation resistance of the edges and corners, resists collision stress, prevents the box from cracking and deforming, and extends the overall life of the protective box; the edges of the rope compartment and umbrella compartment are chamfered and blunted to eliminate sharp edges and prevent the components from being scratched or worn when being taken out or stored (such as balloon breakage or damage to the surface of the rope).

[0013] Optionally, the front end faces of the cover plate and the box body are respectively provided with clamps and buckles for constraint connection, and the upper end face of the cover plate is provided with an inclined support for axial rotation connection; the inclined support acts as a horizontal support for the box body to flip.

[0014] By adopting the above technical solution, the clamps and buckles on the front face of the cover plate and the box body cooperate to form a firm constraint when closed. The inclined support on the upper surface of the cover plate can rotate around the axis. After the cover plate is flipped open, the inclined support can unfold to provide horizontal support for the cover plate: on the one hand, it keeps the cover plate in an open state without manual support; on the other hand, the unfolded cover plate can serve as a working platform, making it convenient to fold the umbrella packs on site. After folding, it can be placed into the umbrella pack compartment to achieve orderly packing.

[0015] Optionally, the upper surface of the cover plate is provided with a rod groove for installing the inclined support, and the rod groove acts as a structural protection when the inclined support is stored; the rear side of the box is provided with a slot hole that mates with the inclined support, and the slot hole adopts an axial rotation section structure.

[0016] By adopting the above technical solution, the groove on the upper surface of the cover plate serves both to install the inclined support and to provide space for its retraction, preventing collisions and wear and maintaining its structural flatness. The slot on the rear side of the housing adopts an axial rotation section structure, facilitating cleaning of the curved structure; it can accommodate the rotation of the inclined support, ensuring stable engagement when the support is extended, providing firm horizontal support for the cover plate, preventing wobbling, and ensuring the stability of the work platform.

[0017] Optionally, a guide groove is provided on the side of the winding shaft, and the winding shaft is fixedly installed in the rope chamber by bolts; the bolts pass through the housing, the connecting shaft, and the winding shaft in sequence, and are fastened to the screw holes provided in the rope chamber; an assembly groove is provided on the upper end face of the housing, the assembly groove acts to protect the nut in the bolt, and a sealing cap is provided on the assembly groove; the connecting hook acts to constrain the end of the weather balloon rope.

[0018] By adopting the above technical solution, the guide groove on the side of the winding shaft can absorb water seepage during rope storage, forming a drainage channel to promptly remove moisture from the rope, preventing moisture residue from causing rope corrosion and protecting the rope structure; and the winding shaft is secured to the rope chamber bolt holes by bolts passing through the shell and connecting shaft in sequence, achieving a stable installation, preventing the winding shaft from loosening during transportation or storage, and ensuring orderly rope storage.

[0019] The mounting groove on the upper surface of the shell can be fitted with protective bolts and nuts, and then covered with a sealing cap to prevent the nuts from being damaged by impact or corroded by moisture, thus maintaining the reliability of the bolt connection; the connecting hook can directly hook onto the end of the weather balloon rope to achieve stable constraint between the balloon and the rope, preventing them from separating during transportation or storage.

[0020] Before connecting the hook and the rope for constraint connection, rotate the shell more than one revolution to apply a continuous elastic deformation force to the torsion spring; ensure that after the constraint connection, the torsion spring outputs an elastic deformation margin and a continuous tensile force.

[0021] Optionally, the umbrella compartment and the rope compartment are connected front to back. Multiple partition slots are alternately arranged on the left and right sides of the umbrella compartment, and the partition slots penetrate the side wall of the box. Clamping partitions are slidably installed on the multiple partition slots. A pin hole is provided at the tail end of the clamping partition, and a locking pin is slidably installed on the pin hole. The locking pin acts to constrain and fix the multiple clamping partitions on one side. Locking buckles are provided at the upper and lower ends of the locking pin, and the locking buckles are constrained and connected to the keyholes provided at corresponding positions on the side wall of the box.

[0022] By adopting the above technical solution, the parachute compartment and the rope compartment are connected front and rear, allowing direct reception of ropes from the rope compartment. This facilitates quick and easy alignment between the rope and the parachute, reducing component adjustment steps during field assembly. The alternating partition grooves on the left and right sides of the parachute compartment allow for sliding of the clamping partitions. By adjusting the spacing between the partitions, different sizes of folding parachutes can be accommodated, achieving precise clamping of the parachute and preventing it from shaking inside the compartment. Locking pins inserted into the pin holes at the ends of the partitions can fix multiple clamping partitions on the same side, preventing the partitions from shifting during transportation. The locking buckles at both ends of the locking pins engage with the keyholes on the box wall, further reinforcing the position of the partitions and ensuring that the folding parachute is securely packed, preventing wear or loosening of the folded shape due to bumps.

[0023] Optionally, fastening beams are respectively provided on the upper and lower end faces of the clamping partition. The fastening beams include base strips and clamping pads. The base strips are located in the middle position of the clamping partition, and multiple clamping pads are provided on the base strips.

[0024] By adopting the above technical solution, the fastening beams on the upper and lower ends of the clamping partition are supported by the central base strip, providing a stable mounting carrier for multiple clamping pads. The clamping pads can elastically deform to conform to the surface of the folded umbrella pack, forming a flexible clamping force that can adapt to folded umbrella packs of different thicknesses, preventing the umbrella pack from shifting or loosening its folded shape due to bumps within the compartment. The base strip is fixed in the middle of the partition, ensuring the overall structural stability of the fastening beams and preventing the fastening beams from shifting when the clamping pads are under force. The multiple clamping pads are evenly distributed, providing multi-point uniform clamping for the umbrella pack, further improving the stability of the umbrella pack after it is packed in the box and reducing friction and wear between the umbrella pack and the partition.

[0025] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects for the shockproof protective box of a weather balloon: More organized component storage and more comprehensive protection: Compared with the single cavity or simple partition design of existing general-purpose boxes, this application achieves separate storage of ropes and umbrellas through the "rope compartment + umbrella compartment" compartment layout.

[0026] More convenient operation and better adaptability: Compared with the existing devices, which are cumbersome to operate and have poor adaptability, the clamps and buckles of the cover plate in this application ensure a firm seal of the box. The inclined support of the shaft connection not only supports the cover plate to keep it open without manual support, but also serves as a platform for folding the parachute. The partition slot of the parachute compartment can adjust the spacing of the clamping partitions. With the fastening beam with clamping pads on the clamping partitions, it can adapt to different sizes of folding parachutes and achieve flexible and stable clamping. The winding shaft is firmly installed with bolts. The housing assembly slot and the sealing cover protect the bolts and nuts. The whole process simplifies the field operation process, reduces the operation intensity of the staff, and adapts to the needs of diverse observation scenarios. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model patent clearer, the technical solutions of the embodiments of this utility model patent will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model patent, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model patent are within the scope of protection of this utility model patent.

[0030] Referring to the accompanying drawings, this application discloses a shockproof protective box for weather balloons.

[0031] Example 1:

[0032] This embodiment provides the basic structure of a shockproof protective box. A shockproof protective box for weather balloons includes four main components: a box body 1, a cover plate 4, a winding shaft 5, and a fastening structure. The specific connection relationships are as follows: The box 1 is a rectangular hollow structure, with two independent cavities divided along its length: the front is the rope compartment 2 and the rear is the parachute compartment 3. Rectangular through slots 11 are opened on the adjacent side walls of the two compartments (the height of the slots 11 is adapted to the height of the adjacent side wall diameter) to realize the component linkage channel between the rope compartment 2 and the parachute compartment 3. The cover plate 4 is a rectangular plate that matches the size of the top surface of the box 1. Its right long side (rear side) is fixedly connected to the right long side (rear side) of the box 1 by a hinge (rotating structure). The cover plate 4 can be flipped around the hinge in the vertical direction to realize the closing and opening of the box 1. The winding shaft 5 is a cylindrical structure, vertically fixed inside the rope chamber 2. Spiral dividing rods 6 are evenly distributed on the outer circumference of the winding shaft 5 (the dividing rods 6 are arc-shaped metal rods with a spiral helix angle of 30°, and the spacing between adjacent dividing rods 6 is adapted to the rope diameter), forming a track for layered winding of the rope; The fastening structure is coaxially assembled at the top of the winding shaft 5, including a connecting shaft 7, a torsion spring 8, and a housing 9. The connecting shaft 7 is a cylindrical metal rod with its lower end vertically welded to the center of the upper end face of the winding shaft 5. The torsion spring 8 is a cylindrical helical torsion spring 8, which is sleeved on the outside of the connecting shaft 7. One end of the spring is embedded in a groove in the side wall of the connecting shaft 7, and the other end is embedded in a groove in the inner wall of the housing 9. The housing 9 is a cylindrical sleeve with an open lower end, which is sleeved on the outside of the torsion spring 8. The outer circumferential surface of the housing 9 is completely overlapped and abutted with the outer circumferential surface of the winding shaft 5 (gap ≤ 0.5 mm). A connecting hook 10 is welded to the outer circumferential surface on the left side of the housing 9 (the connecting hook 10 is adapted to the connecting ring at the end of the weather sounding balloon rope).

[0033] Operating principle Component storage process: Fix one end of the connecting rope of the weather balloon to the bottom of the winding shaft 5, and wind it upwards layer by layer along the track of the spiral divider 6. The front end of the rope passes through the through slot 11 and extends to the parachute compartment 3, where it is fixed with the pre-set connecting buckle of the parachute. After deflating the balloon, fold it and put it into the parachute compartment 3 on the right side of the rope compartment 2. The connecting ring at the end of the rope is fastened to the connecting hook 10. Flip the cover plate 4 to the top of the box 1 to complete the component storage. Fastening structure force: Before fastening the connecting hook 10, rotate the shell clockwise 93 times (causing the torsion spring 8 to twist and generate elastic deformation), so that the torsion spring 8 stores the restoring force; after fastening the balloon connecting ring, the restoring force of the torsion spring 8 is transmitted to the connecting hook 10 through the shell 9, forming a continuous horizontal tension on the end of the balloon rope, preventing the balloon from shifting in the box 1; Opening and closing operation of cover 4: When you need to access a component, flip cover 4 upward (rotate around the hinge) until cover 4 forms a 180° angle with the top surface of box 1, and directly access the rope, balloon and parachute components; after storage, flip cover 4 downward until it fits against the top surface of box 1 to complete the closure.

[0034] Compared to the existing "general-purpose hollow box 1", the core advantage of this embodiment is: The compartmentalized linkage design: By accurately matching the component association requirements of the weather balloon "rope-parachute-balloon" through "rope compartment 2 + parachute compartment 3 + through slot 11", the problem of confusion in retrieval caused by mixed placement of components in the general box 1 is solved. Organized storage structure: The spiral divider bar 6 prevents rope tangling from the source, extending the rope's lifespan; Elastic fastening mechanism: The cooperation between the torsion spring 8 and the connecting hook 10 realizes the "active pulling force fixation" of the balloon, which is a simpler fixation method of placement or foam limiting.

[0035] In a further preferred embodiment, a buckle 13 for clamping and fixing the rope is slidably installed on the through slot 11 to achieve a constrained connection of the front end of the rope.

[0036] Example 2:

[0037] Based on Example 1, structural optimization is performed: The outer side of the box 1 is wrapped with shock-absorbing foam: 5cm thick high-density EVA shock-absorbing foam is used, which is fully wrapped on the outer side of the box 1 (including the top edge, bottom, four sides and four vertical corners) with high-strength glue. The edges of the foam are sealed by heat pressing process to prevent rainwater from seeping into the foam. In the box 1, a circular drainage hole (10mm in diameter) is opened at each of the four corners (near the included corner) of the bottom surface of the rope compartment 2 and the parachute compartment 3. The drainage hole penetrates the bottom surface of the box 1 and the shock-absorbing sponge. The inner wall of the hole is equipped with a rust-proof metal sleeve (to prevent the hole wall from being worn and deformed). Weld an L-shaped stainless steel reinforcing angle steel (30×30×3mm) with the same length as the height of the box body 1 to each of the four vertical corners of the box body 1 (inside the shock-absorbing sponge, at the corner of the box body 1). The angle steel is then fixed to the side wall of the box body 1 with rivets (one rivet is set every 10cm). All inner edges of the rope compartment 2 and the parachute compartment 3 (including the cavity entrance edge and the through slot 11 edge) are treated with mechanical chamfering process with a chamfer radius of 2mm to form a smooth transition arc surface, and the chamfered edge has no burrs or sharp protrusions.

[0038] Operating principle Anti-fall and shock absorption principle: When the box 1 is subjected to external collision or accidental drop, the shock-absorbing sponge on the outside absorbs the impact energy through its own elastic deformation. The remaining impact force is transmitted by the reinforcing angle steel and dispersed to the whole box 1, so as to avoid excessive local stress on the box 1 and cracking.

[0039] Moisture-proof and drainage principle: When the box 1 is used in a rainy environment (such as outdoor rainy day operation), if rainwater seeps into the gaps of the umbrella bag and rope, the water will collect to the bottom of the box 1 under the action of gravity and be quickly discharged outside the box through the four seepage holes to avoid water remaining inside the box.

[0040] Example 3:

[0041] Based on Example 2, the following new structure is added: The clamp 12 and the buckle 13 cooperate: A semi-circular metal clamp 12 (with an anti-slip rubber pad on the inside of the clamp 12) is welded to the middle of the left long side (front face) of the cover plate 4. A cylindrical metal buckle 13 matching the size of the clamp 12 is welded to the corresponding position on the left long side (front face) of the box body 1. When the cover plate 4 is flipped to the closed state, the clamp 12 can rotate around its own axis and fasten to the outside of the buckle 13, forming a constraint connection between the cover plate 4 and the box body 1.

[0042] Installation structure of inclined support 14: A rectangular groove is opened on the upper surface of the cover plate 4. A rotatable metal inclined support 14 (the inclined support 14 is a metal rod structure) is installed in the groove through a hinge (shaft rotation structure). The rotation direction of the inclined support 14 is perpendicular to the flipping direction of the cover plate 4 (i.e., it rotates along the width direction of the cover plate 4). When the inclined support 14 is fully extended, its lower end can contact the ground or the side of the box 1 to form a horizontal support for the cover plate 4.

[0043] Cover plate 4 is closed and fixed: After the components are stored, flip the cover plate 4 downwards to fit the top surface of the box 1, rotate the clamp 12 at the front end of the cover plate 4 so that the clamp 12 is fully engaged with the outside of the buckle 13 at the front end of the box 1. The anti-slip rubber pad increases the friction between the clamp 12 and the buckle 13 to prevent the clamp 12 from loosening during transportation. Cover plate 4 open support: When it is necessary to retrieve components or fold the parachute, first rotate the clamp 12 to disengage from the buckle 13, flip the cover plate 4 upwards to form a 120° angle with the top surface of the box 1, and then rotate and unfold the inclined support 14 from the groove on the upper surface of the cover plate 4. Adjust the length of the inclined support 14 so that the lower end of the inclined support 14 abuts the ground (or the support point on the rear side of the box 1). When the cover plate 4 is kept in a horizontal open state by the inclined support 14 (the upper surface of the cover plate 4 is parallel to the ground), its flat upper surface can be used as a working platform for folding the parachute. The staff can fold the parachute directly on the cover plate 4. After folding, the parachute can be directly put into the parachute compartment 3.

[0044] Example 4:

[0045] Based on Example 3, the following new structure is added: Rod groove 15 setting: Based on the rectangular groove on the upper surface of the cover plate 4, a rod groove 15 that perfectly matches the size of the inclined support 14 is formed (the depth of the rod groove 15 is equal to the diameter of the inclined support 14, and the length is equal to the shortest length of the inclined support 14). A soft rubber pad is laid on the inner side of the rod groove 15 so that the inclined support 14 can be completely embedded in the rod groove 15 when it is stored. A flip-up plastic baffle is set at the opening of the rod groove 15 (to prevent the inclined support 14 from coming out of the rod groove 15 during transportation).

[0046] Slot 16 fits: A slot 16 is made on the rear side of the housing 1 (near the hinge) to fit the lower end of the inclined support 14. The slot 16 adopts an axial rotation section structure (that is, the inner wall of the slot 16 is arc-shaped and fits the cylindrical structure at the lower end of the inclined support 14). A metal bushing is set inside the slot 16. When the inclined support 14 is unfolded, its lower end can be embedded in the slot 16 to form a stable support point (instead of directly touching the ground).

[0047] Operating principle Storage and protection of inclined support 14: After completing the work, first retract the inclined support 14 to the shortest length, rotate the inclined support 14 to disengage from the slot 16 on the rear side of the box 1, then fully embed the inclined support 14 into the rod groove 15 on the upper surface of the cover plate 4, and flip the plastic baffle at the opening of the rod groove 15 to close the rod groove 15, so as to avoid the inclined support 14 from colliding with other parts during transportation. Diagonal support 14 provides stable support: When the cover plate 4 is open, unfold the diagonal support 14 and adjust its length so that the lower end of the diagonal support 14 is aligned with the slot 16 on the rear side of the box 1. Embed the lower end of the diagonal support 14 into the slot 16. The inner wall of the arc-shaped slot 16 fits tightly with the lower end of the diagonal support 14. The metal bushing reduces the friction and wear between the diagonal support 14 and the slot 16, while limiting the lateral displacement of the diagonal support 14 to ensure stable support.

[0048] Example 5:

[0049] Structural Relationships Based on the basic structure of Example 1, the structure is optimized as follows: Design of the guide groove 17: Three axial guide grooves 17 (the guide grooves 17 are V-shaped grooves with a width of 5 mm and a depth of 3 mm) are opened on the outer circumferential surface of the winding shaft 5 (the area between the spiral separator rods 6). The guide grooves 17 extend from the top end of the winding shaft 5 to the bottom end and are connected to the water seepage hole on the bottom surface of the rope chamber 2 (the structure in embodiment 2; if embodiment 2 is not used, a separate guide hole can be opened on the bottom surface of the rope chamber 2).

[0050] Bolt 18 fixing structure: M8 stainless steel bolts 18 are used, which pass through the center hole of the upper end face of the housing 9, the center hole of the connecting shaft 7, and the center hole of the winding shaft 5 in sequence, and finally are threadedly fastened to the screw hole on the bottom surface of the rope chamber 2, so as to realize the rigid connection between the winding shaft 5, the connecting shaft 7, the housing 9 and the rope chamber 2; the nut of the bolt 18 is completely embedded in the assembly groove 19 opened on the upper end face of the housing 9 (the assembly groove 19 is a circular groove with a diameter slightly larger than the diameter of the nut and a depth equal to the thickness of the nut). A circular sealing cover 20 (made of plastic and flush with the upper end face of the housing 9) is fixed above the assembly groove 19 by screws.

[0051] Enhanced function of connecting hook 10: An elastic metal sheet is welded to the inner side of connecting hook 10. When the connecting ring at the end of the weather balloon rope is fastened into hook 10, the elastic metal sheet clamps the connecting ring through its own deformation, preventing the connecting ring from falling off.

[0052] Operating principle Rope moisture-proof principle: When rainwater or water vapor adheres to the surface of the rope, as the rope is wound around the winding shaft 5, the moisture flows downward along the guide groove 17 on the surface of the winding shaft 5, and is finally discharged out of the box through the seepage hole at the bottom of the rope chamber 2, thus preventing moisture from remaining on the surface of the rope.

[0053] The winding shaft 5 is fixed by bolt 18 passing through the housing 9, connecting shaft 7, and winding shaft 5, and fastened to the screw hole of rope chamber 2, forming a rigid fixation from top to bottom, preventing the winding shaft 5 from shaking during transportation; the mounting groove 19 at the upper end of the housing 9 and the sealing cover 20 completely cover the bolt 18 and nut, preventing the nut from being worn by impact or corroded by moisture.

[0054] Example 6:

[0055] Based on the basic structure of Example 1, the component fixing structure of the umbrella compartment 3 is optimized, and the specific connection is as follows: Connecting positions of the compartments: The parachute compartment 3 and the rope compartment 2 are connected in a front-to-back layout (the parachute compartment 3 is located behind the rope compartment 2). The two compartments are connected by the through slot 11 in Embodiment 1. The rope can extend directly from the rope compartment 2 through the slot 11 into the parachute compartment 3 and connect with the parachute. Divider slot 21 is formed by alternating rectangular divider slots 21 on the inner walls of the left and right sides of the umbrella compartment 3 (perpendicular to the length of the compartment). The divider slots 21 on the left and right sides of the inner wall are staggered, with a width of 8 mm, a depth of 10 mm, and a spacing of 20 mm between adjacent slots. The divider slots 21 penetrate the side walls of the umbrella compartment 3 (extending from the top to the bottom of the compartment). Clamping partition 22 assembly: A rectangular clamping partition 22 (made of plastic, 7mm thick, with a height consistent with the height of the umbrella compartment 3) is slidably installed in each partition groove 21. The clamping partition 22 can slide along the length direction of the partition groove 21 (i.e. the width direction of the umbrella compartment 3) to adjust the spacing between adjacent clamping partitions 22. Locking pin 24 and latch 25 design: A circular pin hole 23 (6mm in diameter) is opened at the tail end of each clamping partition 22 (the end closest to the outside of the umbrella compartment 3). Multiple clamping partitions 22 on the same side can be synchronously fixed by a cylindrical locking pin 24 (5mm in diameter, with a length consistent with the height of the umbrella compartment 3) passing through the pin hole 23. A rotatable metal latch 25 (L-shaped) is welded to each of the upper and lower ends of the locking pin 24. A keyhole 26 (rectangular hole) matching the latch 25 is opened at the corresponding position on the side wall of the umbrella compartment 3. After the latch 25 is rotated, it can be fastened into the keyhole 26 to fix the locking pin 24.

[0056] Operating principle Clamping spacing adjustment: Based on the width of the folded umbrella bag, slide the clamping partition 22 along the dividing groove 21 to a suitable position so that the distance between two adjacent clamping partitions 22 is slightly smaller than the width of the umbrella bag (difference 5-10mm), ensuring that the clamping partition 22 forms a slight clamping force on the umbrella bag.

[0057] Synchronous fixing of partitions: After adjusting the position of all clamping partitions 22, insert the locking pin 24 from the top of the umbrella compartment 3 into the pin holes 23 of all clamping partitions 22 on the same side until the lower end of the locking pin 24 extends to the bottom of the umbrella compartment 3. Then rotate the locking buckles 25 at the upper and lower ends of the locking pin 24 so that the locking buckles 25 are fully engaged in the keyholes 26 on the side wall of the umbrella compartment 3 to prevent the locking pin 24 from sliding, thereby fixing the position of the clamping partitions 22.

[0058] The staggered partition grooves 21 and the sliding clamping partitions 22 enable the umbrella compartment 3 to accommodate folding umbrellas of different specifications (width, thickness), solving the limitation of the existing fixed structure of "one compartment, one specification"; Fixing reliability: The double fixing of the locking pins 24 and the locking buckles 25 ensures that the clamping partitions 22 do not shift during transportation, which improves the fixing stability compared to a single sliding structure.

[0059] Ease of operation: The sliding adjustment of the clamping partition 22 and the insertion and removal of the locking pin 24 do not require tools and can be completed by a single person.

[0060] Example 7:

[0061] Structural Relationships Based on the clamping and fixing structure of umbrella compartment 3 in Example 6, the following optimization is made: Fastening beam assembly: A fastening beam (made of plastic, with a length consistent with the width of the clamping partition 22) is fixed on the upper and lower end faces (i.e. the end faces that contact the top and bottom surfaces of the umbrella compartment 3) of each clamping partition 22. The fastening beam is fixed to the clamping partition 22 by screws, and the outer side of the fastening beam is flush with the outer side of the clamping partition 22. The fastening beam consists of a base strip 27 and a clamping pad 28. The base strip 27 is a rectangular strip structure, fixed at the middle of the end face of the clamping partition 22 (centered along the width of the clamping partition 22). The clamping pad 28 is a cylindrical rubber structure (8mm in diameter and 10mm in length), with one end connected to the base strip 27 by a built-in spring, and the other end facing the umbrella pack direction (i.e., the inner side of the clamping partition 22). Three clamping pads 28 are evenly arranged on each base strip 27 (20mm apart).

[0062] Operating principle Flexible clamping principle: After the spacing of the clamping partitions 22 is adjusted and fixed, the clamping pads 28 on the inner side of the clamping partitions 22 come into contact with the surface of the umbrella pack. The clamping pads 28 contract under the squeezing action of the umbrella pack, and the rubber elastically deforms. The elastic force generated by the deformation makes the clamping pads 28 fit tightly against the surface of the umbrella pack, forming a flexible clamping force.

[0063] Multiple points of uniform force: Each clamping partition 22 has 3 clamping pads 28 on its upper and lower end faces, forming 6 evenly distributed clamping points on the umbrella bag, avoiding excessive force on a single point that could cause deformation or damage to the umbrella bag fabric.

[0064] The elastic clamping pad 28 avoids damage to the umbrella bag fabric caused by rigid contact, and is especially suitable for umbrella bags made of thin and easily damaged materials (such as nylon umbrella bags), thus extending the service life of the umbrella bag.

[0065] The multiple evenly distributed clamping pads 28 balance the force on the parachute, preventing the parachute from tilting or shifting due to single-point force during transportation. Compared with a single-point clamping structure, the stability of the fixation is improved.

[0066] The folding and storage process for the umbrella pack is as follows: Based on the width of the folded umbrella pack, slide the clamping partitions 22 in the partition grooves 21 on the left and right inner walls of the umbrella pack compartment 3, adjusting the spacing between the partitions to be slightly less than the width of the umbrella pack; place the folded umbrella pack into the umbrella pack compartment 3 in an orderly manner until it abuts against the corresponding end face, and slide to install the first clamping partition 22 (the bottommost one); ensure that the first clamping partition 22 abuts against the umbrella pack; continue laying the umbrella pack in the opposite direction until it abuts against the end face again, and slide to install the second clamping partition 22 (opposite to the first clamping partition 22); repeat the above operations until the umbrella pack is initially clamped; then use the locking pin 24 to pass through the pin hole 23 of the partition on the same side, rotate the locking pin 24 to the locking buckles 25 at both ends and engage them with the lock holes 26 on the box wall to fix the partition and prevent it from shifting.
