Technical Field

[0001] The present invention relates to the field of insulated fishing boxes, and specifically to a multi-functional insulated portable box that can be used as a seat. Background Art

[0002] A fishing box is an important fishing tool commonly used by fishing enthusiasts. It originated from rock fishing in Japan and is an extremely important auxiliary tool during the fishing process. The initial function of the fishing box was relatively simple, mainly used for keeping cold and storing ice to keep the fish catch fresh. However, with the diversification of fishing activities and the increasing needs of fishermen, the functions of the fishing box have gradually been expanded. It not only has a cold-keeping function but also integrates multiple functions such as a seat, storing fishing gear, and collecting fish catches, becoming an essential comprehensive tool for fishing enthusiasts.

[0003] In fishing activities, the fishing box plays multiple roles: Firstly, it helps fishermen keep the fish catch fresh by ensuring that the fish catch does not deteriorate during long-term storage through its cold-keeping design. Secondly, as a sturdy and comfortable seat, the fishing box allows fishermen to take appropriate breaks during long fishing sessions and relieve physical fatigue. Thirdly, the fishing box also provides space for storing fishing tackle, enabling fishermen to easily organize and store various fishing tools, ensuring the efficiency and convenience of fishing activities.

[0004] Although there are various fishing box products on the market, many existing fishing boxes still have some deficiencies:

[0005] Single functionality: Many traditional fishing box designs are limited to only a cold-keeping function or simple storage functions and cannot meet the multiple needs of fishing enthusiasts.

[0006] Insufficient load-bearing capacity: The designs of traditional fishing boxes lack sufficient load-bearing capacity. Especially when sitting on it for a long time or placing heavy objects, they are prone to deformation or damage.

[0007] Poor anti-slip performance: The bottom design of the fishing box lacks sufficient anti-slip ability in some cases. Especially on wet or uneven ground, it is easy to slide or tilt.

[0008] The handle is not comfortable enough: The handle design of the fishing box may not conform to ergonomics, which may cause discomfort or fatigue when carrying it for a long time.

[0009] Poor heat preservation performance: Although some fishing boxes have a cold-keeping function, most designs still have problems such as limited heat preservation time or weak heat preservation effect, making it difficult to meet the needs of long-term outdoor fishing activities. Summary of the Invention

[0010] The object of the present invention is to provide a multi-functional insulated portable suitcase that can be used as a seat. Through innovative design of traditional fishing boxes, the problems existing in the prior art such as single function, insufficient load-bearing, poor anti-slip effect, poor sealing performance, and poor comfort have been successfully solved.

[0011] To achieve the above object, the present invention provides the following technical solutions: A multi-functional insulated portable suitcase that can be used as a seat, including a box body member, an anti-slip member, a rod tube member, and a handle member, wherein:

[0012] The box body member includes a main box shell and a box cover that cooperate with each other. The main box shell has a box body and an injection-molded bottom plate that are distributed up and down. Reinforcing pieces are provided on both side surfaces of the box body, and a groove is provided at the edge of the opening on the top surface of the box body;

[0013] The anti-slip member is welded to the injection-molded bottom plate on the bottom side of the main box shell. The anti-slip member is an anti-slip bottom bracket, and convex elastic bodies are provided at the bottom of the anti-slip bottom bracket. The design of the elastic bodies effectively prevents the portable suitcase from sliding or tilting during use, especially suitable for outdoor activities or uneven ground environments;

[0014] The rod tube member is provided on the front side or the rear side of the box body. The rod tube member includes a connecting portion and a rod tube body. The connecting portion is welded to the outside of the box body in a whole circle, and the rod tube body is provided on the connecting portion. The rod tube body is a rod tube bracket with openings at both the upper and lower ends;

[0015] The handle member is arranged on the left and right sides of the box body. The handle member is a hook-type handle, and the handle member includes a handle fixing piece and a handle rod.

[0016] Preferably, a magnetic adsorption sealing ring A is embedded in the groove. The box cover is connected to the main box shell through a connecting band. A convex connecting edge is provided on the side of the box cover facing the box body, and the convex connecting edge is fitted into the groove at the opening on the top surface of the box body. A magnetic adsorption sealing ring B that cooperates with the magnetic adsorption sealing ring A is embedded in the convex connecting edge.

[0017] Preferably, the outer sides of the main box shell and the box cover are sewn with a binding edge, and the connecting surface of the binding edge is connected by a zipper. Through the design of magnetic adsorption and zipper, when the box cover is closed, the magnetic adsorption sealing ring can firmly adsorb on the groove and the convex connecting edge of the box body, forming a tight seal. This magnetic adsorption sealing design can effectively avoid heat insulation leakage. The use of the zipper can provide a stronger sealing effect than ordinary sewing, and is more convenient when opening and closing. The zipper design makes it more convenient for users to open and close the box body frequently, and can form a solid barrier when sealed, further isolating the influence of the external environment.

[0018] Preferably, the opening at the upper end of the rod barrel bracket is designed to be convex, which protrudes outward by 12 mm, and the opening at the lower end of the rod barrel body is set inwardly and tilted upward. The rod barrel component is fixed to the box body by a full circle welding method, which enhances the force-bearing capacity of the box body and enables it to withstand greater external forces. The design of the 12 mm convexity at the upper end of the rod barrel body makes the structure more stable and helps to disperse external pressure. The rod barrel design also includes a rod insertion hole composed of an upper opening and a lower opening to avoid interference from the side fixing plate.

[0019] Preferably, the handle fixing plate includes a main fixing plate and two auxiliary fixing plates, wherein a protruding hanging frame is provided in the middle of the main fixing plate, and the hanging frame can provide auxiliary fixing functions for fishing accessories such as ear spoons, fish control inserts, towels, etc., and two auxiliary fixing plates are distributed on both sides of the main fixing plate, and the two auxiliary fixing plates and the main fixing plate are welded to the outside of the box body in a full circle. Through high-precision welding technology, the connection part between the handle fixing plate and the box body is flat and smooth, avoiding the abrupt seams that may appear in traditional screws or other fixing methods, and enhancing the overall sense of refinement. In addition, due to the structural design of the main fixing plate and the auxiliary fixing plate, the handle can provide a comfortable grip. Even when carried for a long time, the handle can effectively disperse the load, reduce the user's hand pressure, and improve the comfort during use.

[0020] Preferably, the handle rod comprises a connecting belt, a carrying rod and a hooking strap, the bottom end of the connecting belt is movably connected to the main fixing plate and the two auxiliary fixing plates through a movable buckle, the top end of the connecting belt is provided with a carrying rod, and the carrying rods on both sides of the box body are connected by a hooking strap. The design of the handle can be hooked, and the center of gravity is more comfortable. When in use, the handle can be placed flat on the box cover, and when opened, the handle can be rotated and perpendicular to the side of the box body, effectively reducing the space occupied by the handle during carrying and not affecting surrounding movements.

[0021] Preferably, the reinforcement sheet is high-frequency welded to the inside of the box body, and the reinforcement sheet is made of a high-strength EVA sheet sandwiched between hard plastic or sheet sandwiched between metal materials. The reinforcement sheet adopts a high-frequency welding process to firmly combine it with the box body, thereby improving the stability and impact resistance of the overall structure. In addition, the provision of the reinforcement sheet enhances the compression resistance of the box body, ensuring that the box body will not deform when bearing heavy objects; in addition, the reinforcement sheet not only improves the load-bearing capacity of the box body, but also makes the box body have a "sitable" function. In camping, fishing and other occasions, users can sit on the box body, and the box body is not easily deformed due to excessive load, ensuring that long-term sitting and use will not cause discomfort or damage.

[0022] Preferably, a heat preservation layer is provided inside the box body, and the heat preservation layer is a 20 cm thick EVA material, which can effectively isolate the external temperature fluctuations and ensure that the items in the box maintain a constant temperature for a long time. The use of EVA material makes the heat preservation layer both light and has excellent heat insulation effect, which is suitable for long-term storage of food, fish, etc.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] Through the innovative design of the traditional fishing box, the present invention successfully solves the problems of single function, insufficient load-bearing capacity, poor anti-slip effect, poor sealing performance, and poor comfort in the prior art. The specific technical effects are as follows:

[0025] Multi-functional integration to meet different needs: The suitcase of the present invention integrates multiple functions such as cold preservation, a sitting stool, storing fishing gear and fish catches, etc. Its heat preservation layer can effectively isolate the external temperature change and keep the items in the box at a constant temperature, which is especially suitable for long-term outdoor fishing activities. Through the integration of these functions, the suitcase can not only meet the needs of storing items and heat preservation during fishing, but also be used as a convenient sitting stool to improve the comfort of fishermen.

[0026] Enhanced load-bearing capacity: High-strength reinforcement sheets and high-frequency welding processes are adopted to improve the structural stability and compressive capacity of the box body. When bearing a large weight, the box body is not easily deformed, ensuring stability and safety during long-term use. The reinforcement sheet design enables the box body to have the "sitting" function. Even during long-term use of the seat cushion, the box body will not deform due to excessive force, providing a more comfortable and reliable use experience.

[0027] Excellent anti-slip performance: Through the anti-slip bottom support design and elastomer wrapping technology, the friction between the bottom of the box body and the ground is enhanced, avoiding sliding or tilting on smooth or wet ground. The exposed design of the elastomer provides better grounding force for the bottom, especially suitable for uneven or slippery ground environments, ensuring the stability of the box body.

[0028] Improved sealing and heat preservation effects: By adopting a magnetic adsorption sealing ring and zipper design, the sealing performance of the box body is ensured. When the box cover is closed, the magnetic adsorption sealing ring can firmly adsorb on the groove body and the convex connecting edge of the box body to form a tight seal, effectively avoiding heat preservation leakage. The zipper design provides a stronger sealing effect than ordinary stitching, and at the same time, it is also convenient for users to easily open the box cover when needed. Moreover, the heat preservation layer uses EVA material, which has good heat insulation performance, ensuring that food, fish catches and other items are kept at a constant temperature during long-term storage, and improving the heat preservation effect.

[0029] Comfortable handle design: The handle part adopts a hook-type handle design, combined with a high-precision welding process. The connection between the handle and the box body is flat and smooth, which not only enhances the comfort of the handle, but also avoids the abrupt joint problems that may be caused by traditional fixing methods, improving the overall aesthetics and use experience of the box body. The handle design can effectively disperse the load and reduce the pressure on the user's hand, which is suitable for long-term carrying and use. Description of the Drawings

[0049] Embodiment 3 significantly improves the carrying experience, comfort, space utilization rate, and appearance aesthetics through the high-precision welding process, hook-type handle design, and reasonable ergonomic design. This design optimization ensures the comfort and convenience of the portable suitcase during use.

[0050] Embodiment 4: Please refer to Figures 1-4 , the present invention provides a technical solution: a multi-functional insulated portable suitcase that can be seated, including a box body component, a handle component 4, and an anti-slip component 5. The box body component includes a main box shell 1 and a box cover 2 that cooperate with each other. The main box shell 1 has a box body and an injection-molded bottom plate that are distributed vertically. The anti-slip component 5 is welded to the injection-molded bottom plate on the bottom side of the main box shell 1. The anti-slip component 5 is an anti-slip bottom tray 501, and a protruding elastic body 502 is provided at the bottom of the anti-slip bottom tray 501. The design of the elastic body 502 effectively prevents the portable suitcase from sliding or tilting during use, especially suitable for outdoor activities or uneven ground environments.

[0051] In specific implementation, the bottom of the box body is first preliminarily formed by an injection molding process to form the basic shape and structure of the bottom (injection molded bottom plate). The injection molding process has high precision, which can ensure the stability and consistency of the bottom shape, and at the same time can also ensure the strength foundation of the bottom of the box body; on the preliminarily injection molded bottom, secondary welding is carried out to install anti-slip accessories. These anti-slip accessories usually use materials with elastomer 502 characteristics, such as rubber, TPE (thermoplastic elastomer 502), etc., and are firmly combined with the bottom through a precision welding process. The welding process ensures the tight combination of the anti-slip accessories and the injection molded bottom, improving the friction between the bottom and the ground; the elastomer 502 part in the anti-slip accessories can generate sufficient friction when contacting the ground, avoiding the bottom from sliding on a smooth or slippery ground and ensuring the stable placement of the box body; in order to further enhance the anti-slip effect, the elastomer 502 part is wrapped with EVA material. EVA (ethylene-vinyl acetate copolymer) is a material with excellent elasticity and wear resistance, which can effectively wrap the elastomer 502 and make it firmly adhere to the injection molded bottom. The wrapping of EVA makes the bottom not only have anti-slip effect, but also increase wear resistance and anti-aging ability. The EVA molding material can provide additional protection for the elastomer 502, preventing it from being worn, aged or falling off due to long-term use, and extending the service life of the anti-slip accessories. At the same time of EVA wrapping, part of the elastomer 502 is designed to be exposed on the bottom surface to directly contact the ground. These exposed elastomer 502 can provide better friction, ensuring that the box body can be stably placed in any environment, avoiding sliding or tilting, and is especially suitable for outdoor, wet or uneven ground. In addition, the inner side of the bottom support uses an EVA film welding process to sandwich the EVA film and the rigid plastic sheet together. This structural design provides a strong support and uniform pressure distribution for the bottom.

[0052] In the above-mentioned Embodiment 4, the anti-slip effect of the bottom of the box body is optimized, significantly improving the stability, durability and anti-slip ability of the box body in different environments.

[0053] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
