[0050] 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.

[0051] Please see Figures 1-5The present invention provides the following technical solution: a multi-functional fishing tool cart, including a base 1, lockable universal wheels 2 diagonally fixed to the bottom surface of the base 1, and an operating part 3 located at one end of the top surface of the base 1. A storage box 4 is fixed on the top surface of the base 1. The cart also includes a positioning frame 6, a fish storage box 7, a drain outlet 9, a manual valve 10, and a first manual bolt 11.

[0052] Furthermore, by Figure 1 As shown, in this embodiment, the positioning frame 6 is fixed to the top surface of the base 1, the bottom end of the fish storage box 7 is embedded in the positioning frame 6 to form an insert structure, and two symmetrically distributed lifting handles 71 are fixed on the fish storage box 7. The drain outlet 9 is fixed to the bottom of the outer side of the fish storage box 7 and communicates with the internal space of the fish storage box 7. The manual valve 10 is fixed to the drain outlet 9. The first manual bolt 11 is installed on the positioning frame 6 by thread engagement, and one end of it is attached to the outer wall of the fish storage box 7. After adopting the above scheme, when the user needs to go to the fishing location, he first releases the locking state of the locking universal wheel 2, pushes the base 1 through the operating part 3, and uses the flexible steering characteristics of the locking universal wheel 2 to easily move the tool cart to the target position.

[0053] Upon arrival at the fishing spot, lock the locking caster wheel 2 to ensure the tool vehicle is parked stably and to prevent displacement due to uneven ground or external forces.

[0054] When installing the fish storage box 7, align its bottom end with the positioning frame 6, use the insertion structure to embed the fish storage box 7 into the positioning frame 6, and then rotate the first manual bolt 11. Through the thread engagement, make one end of it gradually fit against the outer wall of the fish storage box 7, thereby firmly fixing the fish storage box 7 in the positioning frame 6 to prevent it from shaking or falling off during transportation or use.

[0055] When it is necessary to move the fish storage box 7, the user can hold the symmetrically distributed lifting handles 71 to lift the fish storage box 7 easily and effortlessly.

[0056] During fishing, the fish caught can be temporarily stored in the fish storage box 7. When the fish storage box 7 needs to be cleaned, open the manual valve 10. Since the drain outlet 9 is connected to the internal space of the fish storage box 7, the sewage and debris in the fish storage box 7 can be discharged through the drain outlet 9. After cleaning, close the manual valve 10 to prevent debris from entering or liquid from leaking.

[0057] Storage box 4 is fixed to the top surface of base 1 and can be used to store bait, fishing gear accessories and other items needed for fishing, making it convenient for users to access them at any time, making the whole fishing process more convenient and efficient. Through the coordinated cooperation of various components, this multi-functional fishing tool cart realizes multiple functions such as movement, fixing, fish storage, sewage discharge and item storage, providing fishing enthusiasts with a convenient user experience.

[0058] Preferably, by Figure 1 and Figure 5 As shown, this embodiment also includes: a flip cover 8, a first magnetic clasp 15, and a second magnetic clasp 16. The flip cover 8 is hinged to the top of the fish storage box 7. Ventilation holes 81 are evenly provided on the flip cover 8, and a second fixing block 82 is fixed at the free end of the flip cover 8. A first fixing block 72 is fixed on the outer wall of the fish storage box 7. The first magnetic clasp 15 is fixed to the top surface of the first fixing block 72, and the second magnetic clasp 16 is fixed to the bottom surface of the second fixing block 82 and attracts the first magnetic clasp 15. With the above solution, when the fish caught need to be temporarily stored in the fish storage box 7, the user can support the fish storage box 7 stably by lifting the handle 71, flip the flip cover 8 upward (using the hinge structure to open and close), and put the fish into the fish storage box 7.

[0059] The evenly spaced ventilation holes 81 on the flip cover 8 ensure air circulation between the inside of the fish tank 7 and the outside, preventing fish from dying due to prolonged lack of oxygen, while also preventing water from splashing out or small fish from jumping out of the fish tank 7.

[0060] When the flip cover 8 is closed, the second magnetic piece 16 on the bottom surface of the second fixing block 82 at the free end of the flip cover 8 will automatically engage with the first magnetic piece 15 on the top surface of the first fixing block 72 on the outer wall of the fish storage box 7. Through the principle of attraction between opposite magnetic poles, a stable closed locking structure is formed. No additional buckles or bolts are required, and the opening and closing operation can be completed with one hand.

[0061] If a deep cleaning or internal inspection of the fish storage tank 7 is required, the fish storage tank 7 can be loosened from the positioning frame 6 by first using the first manual bolt 11, and then the fish storage tank 7 can be moved as a whole using the lifting tool 71 (if it is heavy, the manual valve 10 on the drain outlet 9 can be opened first to drain the sewage in the fish storage tank 7 through the drain outlet 9, and then the fish storage tank 7 can be removed for deep cleaning).

[0062] At this time, the flip cover 8 can remain open, and in conjunction with the bottom drain 9, ensures a hygienic and comfortable environment for storing fish.

[0063] Preferably, by Figure 1 and Figure 2 As shown, this embodiment also includes: a single door 43, a second positioning block 12, and a second manual bolt 13. The storage box 4 has a first storage cavity 41. The single door 43 is hinged to the opening end of the first storage cavity 41, and a first positioning block 432 is fixed to the free end of the single door 43. The second positioning block 12 is fixed to the outer wall of the storage box 4, and a threaded hole 121 is machined on the second positioning block 12. The second manual bolt 13 passes through the first positioning block 432 and is threadedly engaged with the threaded hole 121. With the above solution, when it is necessary to take out the items in the storage box 4, the user first rotates the second manual bolt 13 to separate it from the threaded hole 121 on the second positioning block 12, thereby releasing the lock on the single door 43.

[0064] Since the single door 43 is connected to the opening end of the first storage cavity 41 through a hinge structure, it can be flipped outward along the hinge axis to open and expose the internal storage space. The first storage cavity 41 can be used to classify and store fishing gear such as fishing rods, or to place personal items such as drinking water and snacks, to meet the diverse storage needs during fishing.

[0065] When the single door 43 is closed, the first positioning block 432 aligns with the second positioning block 12 on the outer wall of the storage box 4. Then, the second manual bolt 13 is rotated clockwise so that it passes through the through hole of the first positioning block 432 and the threaded hole 121 of the second positioning block 12 in sequence. Through the axial tension generated by the threaded engagement, the single door 43 is tightly fitted to the opening end of the first storage cavity 41.

[0066] When closed, the single door 43 forms a reliable sealed space, meeting the waterproof and dustproof requirements of complex outdoor environments and ensuring the safety and integrity of stored items.

[0067] Preferably, by Figure 1 As shown, this embodiment also includes a transparent observation window 431, which is embedded and fixed inside the single door 43. With the above solution, when using the device, the user does not need to open the single door 43. Through the transparent observation window 431 embedded in the single door 43, the user can directly observe the storage status of the items in the first storage cavity 41, such as the remaining amount of bait and the classification and placement of fishing gear. This avoids wasting time due to blindly searching, and greatly improves operational efficiency, especially when it is necessary to quickly change fishing tackle or replenish bait during fishing.

[0068] Preferably, by Figure 1 and Figure 3 As shown, this embodiment also includes: a drawer 44, the storage box 4 has a second storage cavity 42, the drawer 44 is slidably installed in the second storage cavity 42, and the drawer 44 has multiple independent storage compartments 441. With the above solution, when it is necessary to take out the items in the second storage cavity 42, the user pulls the handle of the drawer 44 and uses its sliding installation structure with the inner wall of the second storage cavity 42 to smoothly pull the drawer 44 out of the storage box 4.

[0069] The drawer 44 has multiple independent storage compartments 441 inside, which can be divided and stored according to the type of items. For example, small fishing gear such as fishing hooks, sinkers, and bobber beads can be stored in different storage compartments 441, or electronic devices such as spare batteries and mobile phone chargers can be isolated from other miscellaneous items to prevent them from getting tangled or damaged by collision.

[0070] When drawer 44 is fully pulled out, the open design of storage compartment 441 makes it easy for users to directly take out or put back items. The size of a single storage compartment 441 can be customized according to common fishing gear specifications (e.g., a long storage compartment 441 is suitable for storing fishing line spools, and a square compartment is suitable for placing bait boxes).

[0071] When closing drawer 44, push drawer 44 to slide in the opposite direction until it is fully embedded in the second storage cavity 42.

[0072] Through the layered design of the first storage cavity 41 (single door 43 structure) and the second storage cavity 42 (drawer 44 structure), the storage box 4 achieves the complementary functions of "open access for large items" and "classified and refined storage of small items". Users can flexibly utilize the upper and lower storage spaces according to the actual needs of the fishing scene. With the transparent observation window 431 for visual management of the items on the upper layer, the practicality and convenience of the tool cart in the outdoor environment are significantly improved.

[0073] Preferably, by Figure 1 and Figure 3 As shown, this embodiment also includes: a guide slider 442 and a third manual bolt 14. The guide slider 442 is fixed to the outer wall of the drawer 44. A limiting sliding hole 45 is provided on the storage box 4. The guide slider 442 slides with the limiting sliding hole 45. The third manual bolt 14 is installed on the guide slider 442 by thread engagement. With the above solution, when the drawer 44 needs to slide, the guide slider 442 moves linearly along the limiting sliding hole 45 of the storage box 4.

[0074] When it is necessary to secure drawer 44 (such as to prevent drawer 44 from sliding out when the tool cart is moved), the user rotates the third manual bolt 14 clockwise, and the end of the bolt gradually extends into the threaded hole of the guide slider 442 through the thread engagement, thereby locking the position of drawer 44 by friction.

[0075] Preferably, by Figure 1 and Figure 4 As shown, this embodiment also includes an umbrella holder 5 fixed to the top of the storage box 4. The umbrella holder 5 includes: a support rod 51 fixed to the top of the storage box 4, a fixed semicircular hoop 52 fixed to the support rod 51, a movable semicircular hoop 53 hinged to the fixed semicircular hoop 52, a flip screw 54 hinged to the fixed semicircular hoop 52, a wing nut 55 threaded onto the protruding end of the flip screw 54, and a rubber liner 56. The free end of the movable semicircular hoop 53 has a notch 531, and the flip screw 54 passes through the notch 531. The rubber liner 56 is glued and fixed to the inner walls of both the fixed semicircular hoop 52 and the movable semicircular hoop 53. With the above solution, when the user needs to set up a sun umbrella or umbrella at the fishing spot, he first flips the movable semicircular hoop 53 through the hinge structure to separate it from the fixed semicircular hoop 52.

[0076] Insert the umbrella handle vertically into the fixed semicircular hoop 52 (the support rod 51 provides a vertical support reference). After adjusting the umbrella body to a suitable angle, flip the movable semicircular hoop 53 so that the notch 531 at its free end is aligned with the flip screw 54. At this time, the inner wall rubber lining 56 of the fixed semicircular hoop 52 and the movable semicircular hoop 53 are in contact with the outer surface of the umbrella handle. The elastic deformation of the rubber generates initial friction force to initially fix the position of the umbrella handle.

[0077] Then, rotate the wing nut 55 clockwise so that it moves along the thread engagement direction of the flip screw 54, pushing the movable semicircular hoop 53 toward the fixed semicircular hoop 52.

[0078] As the wing nut 55 is tightened, the rubber lining 56 of the inner walls of the two semi-circular hoops is further squeezed to the surface of the umbrella handle, forming a ring-shaped clamping force.

[0079] When it is necessary to disassemble the umbrella, loosen the wing nut 55 counterclockwise, manually open the movable semicircular hoop 53, and the umbrella handle can be removed from the fixed semicircular hoop 52.

[0080] Preferably, by Figure 1 As shown, in this embodiment, the operating part 3 includes: two symmetrical connecting arms 31 fixed to the top surface of the base 1, a grip 32 fixed between the two connecting arms 31, and a rubber sleeve 33 fixed to the grip 32. With the above solution, when the user pushes the tool cart to move, he holds the grip 32 with both hands, and the symmetrically distributed connecting arms 31 fix the grip 32 to the central area of ​​the top surface of the base 1 (or the operating height that conforms to ergonomics), forming a stable force fulcrum.

[0081] The rubber sleeve 33 is made of nitrile rubber or EVA foam and is fixed to the grip bar 32 with glue. When the hand holds it, the elastic deformation of the rubber sleeve 33 conforms to the curve of the palm, disperses the pressure generated by the thrust, and reduces hand fatigue caused by holding it for a long time.

[0082] Components not described in detail in this article are existing technologies.

[0083] The working principle and usage process of this utility model: When using the fishing tool cart of this utility model, when the user needs to go to the fishing location, first release the locking state of the locking universal wheel 2, push the base 1 through the operating part 3, and use the flexible steering characteristics of the locking universal wheel 2 to easily move the tool cart to the target position.

[0084] After arriving at the fishing spot, lock the locking caster wheel 2 to park the tool vehicle stably and prevent displacement due to uneven ground or external forces.

[0085] When installing the fish storage box 7, align its bottom end with the positioning frame 6, use the insertion structure to embed the fish storage box 7 into the positioning frame 6, and then rotate the first manual bolt 11. Through the thread engagement, make one end of it gradually fit against the outer wall of the fish storage box 7, thereby firmly fixing the fish storage box 7 in the positioning frame 6 to prevent it from shaking or falling off during transportation or use.

[0086] When it is necessary to move the fish storage box 7, the user can hold the symmetrically distributed lifting handles 71 to lift the fish storage box 7 easily and effortlessly.

[0087] During fishing, the fish caught can be temporarily stored in the fish storage box 7. When the fish storage box 7 needs to be cleaned, open the manual valve 10. Since the drain outlet 9 is connected to the internal space of the fish storage box 7, the sewage and debris in the fish storage box 7 can be discharged through the drain outlet 9. After cleaning, close the manual valve 10 to prevent debris from entering or liquid from leaking.

[0088] Storage box 4 is fixed to the top surface of base 1 and can be used to store bait, fishing gear accessories and other items needed for fishing, making it convenient for users to access them at any time, making the whole fishing process more convenient and efficient.
