Description

Technical Field

[0001] This utility model relates to the field of fishing box technology, and in particular to a fishing box and its retractable support leg structure. Background Technology

[0002] A fishing box is an auxiliary tool used in fishing activities to store fishing gear and catches, and also functions as a seat. Originally designed for storing ice to keep fish fresh, it is often used in competitions or long fishing trips, requiring high-strength storage and stability. While traditional fishing boxes can remain stable on relatively flat, hard surfaces, they are prone to instability in common wild fishing environments such as soft mud, slopes, or rocky beaches. Even with adjustable feet, some products struggle to maintain a level position when the slope exceeds a certain angle. This can cause the box to shake or even tip over during fishing, affecting the smoothness of the fishing operation and potentially causing the fishing tackle inside to slip and get damaged. Therefore, there is an urgent need to design a fishing box with extendable legs. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fishing box and its retractable support leg structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A fishing box and its retractable support leg structure include a fishing box body. Each of the four corners of the fishing box body has foot covers installed inside by several screws. A lifting tube passes through the foot cover and is slidably connected to the inner wall of the fishing box body. A spring is fixed between the top end of the lifting tube and the fishing box body. A pawl is bolted to the bottom end of the lifting tube. A switch is movably installed on the outer wall of the foot cover. A spring is fixed between the upper end of the switch and the outer wall of the foot cover. A gear is fixed to the lower end of the switch near the lifting tube.

[0005] As a further embodiment of this utility model, corner protectors are installed at the four corners of the bottom of the fishing box body by screws, and bearings are fixed to the outer wall of the foot cover.

[0006] As a further embodiment of this utility model, the bottom ends of the four sets of corner protectors are all fixed with rubber feet, and the middle position of the switch is connected through the bearing.

[0007] As a further embodiment of this utility model, a groove is provided on the side of the lifting tube near the switch, and the gear is engaged in the groove on the lifting tube.

[0008] As a further embodiment of this utility model, a limit block is fixed at the top of the switch, and the limit block is located inside the main body of the fishing box.

[0009] As a further embodiment of this utility model, a sealing ring is installed on the lower inner wall of the foot cover by screws, and the switch passes through a slot opened in the side wall of the fishing box body.

[0010] Compared with the prior art, the present invention has the following beneficial effects: By incorporating components such as a lifting tube, ground claws, spring 1, spring 2, a switch, and limit blocks, when the fishing box is placed on uneven terrain such as slopes or rocky beaches, pressing the switch utilizes the lever action of the bearing to compress spring 2, causing the lower end to lift and disengage the gear from the groove of the lifting tube, thus releasing the lock. At this time, the lifting tube can flexibly extend and retract under the elastic force of spring 1, adjusting the height of the ground claws. Once the appropriate height is reached, releasing the switch resets spring 2, and the gear re-engages with the lifting tube to lock, fixing the corner at the adjusted height. Since the four corners can be independently height-adjusted, the extension length of each ground claw can be precisely adjusted according to the undulations of different terrains, ensuring that all corners of the box can stably contact the ground, effectively counteracting the tilting force caused by uneven terrain. At the same time, after the ground claws and lifting tube are retracted, the fishing box can be easily carried by the user. Attached Figure Description

[0015] Reference Figures 1-6 A fishing box and its retractable support leg structure include a fishing box body 1. Each of the four corners of the fishing box body 1 is fitted with a foot cover 5 by a number of screws. A lifting tube 4 runs through the foot cover 5. The lifting tube 4 is slidably connected to the inner wall of the fishing box body 1. A spring 7 is fixed between the top of the lifting tube 4 and the fishing box body 1. A ground claw 12 is installed at the bottom of the lifting tube 4 by bolts. A switch 3 is movably installed on the outer wall of the foot cover 5. A spring 8 is fixed between the upper end of the switch 3 and the outer wall of the foot cover 5. A gear 11 is fixed on the lower end of the switch 3 near the lifting tube 4.

[0016] By pressing the corresponding switch 3, under the lever action of bearing 10, the upper end of switch 3 compresses spring 8, and the lower end lifts up, driving gear 11 away from lifting tube 4, thus releasing the lock on lifting tube 4. At this time, lifting tube 4 will flexibly extend and retract under the elastic force of spring 7 or under the action of external force, driving the ground claw 12 to adjust the height. Observe whether the fishing box body 1 is stable. After adjusting to the appropriate height, release switch 3, spring 8 returns to its original position, and gear 11 re-engages with the groove of lifting tube 4 to complete the lock, fixing that corner at the adjusted height. Adjust the height of the ground claw 12 of other corners in the same way until the fishing box body 1 is placed stably. After use, press the switch 3 of each corner again to release the lock, retract the lifting tube 4 and ground claw 12, so that they are completely inserted into the fishing box body 1 and fitted into the foot cover 5, and release switch 3 to complete the lock. The user can quickly carry it away, improving the convenience of use.

[0017] In this embodiment, corner protectors 2 are installed at the four corners of the bottom of the fishing box body 1 by screws, and bearings 10 are fixed to the outer wall of the foot cover 5.

[0018] The rubber foot pad 6 is made of hard rubber. When the corner protector 2 is used in conjunction with the rubber foot pad 6, it can increase the friction between the fishing box body 1 and the ground, while preventing the corner protector 2 from directly contacting the ground and causing wear, thus playing a role in anti-slip and anti-scratching.

[0019] In this embodiment, the bottom ends of the four sets of corner protectors 2 are all fixed with rubber feet 6, and the middle part of the switch 3 is connected to the bearing 10.

[0020] The sealing ring 13 is made of soft rubber. It can prevent dirt, sand and other impurities from entering the foot cover 5, protect the components of the lifting mechanism, reduce wear and malfunctions, and extend the service life of the fishing box body 1.

[0021] In this embodiment, a groove is provided on the side of the lifting tube 4 near the switch 3, and the gear 11 is fitted into the groove on the lifting tube 4.

[0022] When switch 3 is rotated, it causes limit block 9 to contact the inner wall of the fishing box body 1, limiting the range of motion of the switch, thus preventing the switch from falling out of the foot cover 5 and ensuring that the locking and unlocking functions work normally.

[0023] In this embodiment, a limit block 9 is fixed at the top of the switch 3, and the limit block 9 is located inside the fishing box body 1.

[0024] The height of the ground claw 12 can be adjusted by extending and retracting the lifting tube 4, and it can be completely retracted into the box, making it more stable under the pressure of the rubber foot pads 6.

[0025] In this embodiment, a sealing ring 13 is installed on the lower inner wall of the foot cover 5 by screws, and the switch 3 passes through the slot opened on the side wall of the fishing box body 1.

[0026] The foot covers 5 are modularly installed, making them easier to install and remove.

[0027] From the above description, it can be seen that the above-described embodiments of this utility model achieve the following technical effects: After carrying the fishing box body 1 to the fishing spot, it is first placed on the ground. If the ground is uneven, adjustments can be made to each corner. By pressing the switch 3 at the corresponding corner, under the lever action of the bearing 10, the upper end of the switch 3 compresses the second spring 8, and the lower end lifts up, causing the gear 11 to disengage from the groove of the lifting tube 4, thus releasing the lock on the lifting tube 4. At this time, the lifting tube 4 will flexibly extend and retract under the elastic force of the first spring 7 or under the action of external force, driving the ground claw 12 to adjust the height. Observe whether the main body 1 of the fishing box is stable. After adjusting to a suitable height, release switch 3. Spring 2 8 will return to its original position, and gear 11 will re-engage with the groove of the lifting tube 4 to complete the locking, fixing that corner at the adjusted height. Adjust the height of the ground claws 12 of the other corners in the same way until the main body 1 of the fishing box is placed stably. After use, press the switch 3 of each corner again to release the lock. Retract the lifting tube 4 and ground claws 12 so that they are completely inserted into the main body 1 of the fishing box and fitted into the foot cover 5. Release switch 3 to complete the locking, and you can take it away.
