Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for fishing tackle, and in particular to a novel fishing rod box. Background Technology

[0002] With the increasing popularity of outdoor fishing, rod boxes have become an essential piece of equipment for anglers, serving as an important container for storing fishing rods, floats, and fishing lines. In actual use, fishing environments are usually located in reservoirs, riverbanks, or wild ponds. These locations have complex and varied terrain, with uneven, muddy, damp, and even rocky and weedy surfaces.

[0003] Most existing traditional fishing rod boxes adopt a flat-bottomed rectangular structure design, focusing primarily on internal storage while neglecting the need for placement in complex outdoor environments. When anglers arrive at their fishing spot, they often have no choice but to place the rod box directly on the ground. This not only easily leads to the box surface getting dirty and scratched, but also makes it prone to sliding or even tipping over when the ground is sloping or slippery, affecting the safety of the fishing gear inside. Although some anglers carry an additional stand, this undoubtedly increases the weight and cumbersomeness of carrying the box, failing to achieve a self-supporting design.

[0004] Furthermore, waterproof performance is also a key indicator of rod case quality. Existing rod cases typically rely solely on a rigid fit between the lid and the edge of the case, or the addition of static rubber strips, for sealing. This passive sealing structure requires high precision in manufacturing and strong elasticity in the rubber strips. Over time, the rubber strips tend to age and harden, or the locking force of the buckles may weaken, leading to tiny gaps between the lid and the case. In rainy weather or when splashed by waves, external moisture can easily seep into the case through these gaps, causing expensive carbon fiber rods to become damp, moldy, or even damaged. This fails to meet the protection requirements for all-weather fishing. Therefore, a new type of rod case is proposed to address these issues. Utility Model Content

[0005] In view of the problems in the existing technology of fishing rod boxes, such as the inability to provide stable support and adjust the height in complex outdoor terrain, and the unreliable sealing performance of the static rubber strips used in the box sealing structure due to aging or foreign object interference, this utility model aims to provide a new type of fishing rod box with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a novel fishing rod box, comprising: a box body, a box cover, a buckle, a retractable support mechanism, and a sealing mechanism.

[0007] The retractable support mechanism includes: a hollow column, a limiting slip ring, a support column, a telescopic assembly, a telescopic column, and a support plate. The hollow column is fixedly connected to the bottom of the housing. The telescopic column is slidably inserted into the interior of the hollow column. The support plate is fixedly connected to the top of the telescopic column and contacts the bottom of the housing, providing support and lifting for the housing in its extended state. The support column rotates around the hollow column, forming the basic structure of a tripod. The limiting slip ring is slidably fitted onto the outside of the hollow column, releasing or locking the retracted support column through its up-and-down sliding motion. The telescopic assembly connects the support columns, maintaining the triangular support shape of the support columns after deployment.

[0008] The sealing mechanism is located at the contact gap between the housing and the lid, and includes a sealing ring, an air groove, a piston, a push rod, and a spring. The sealing ring is pre-installed at the contact gap. The air groove is formed inside the side wall of the housing, the piston is slidably connected to the air groove, and the push rod is fixedly connected to the top of the piston, extending to the contact gap. The spring is located in the air groove and abuts against the bottom of the piston. When the lid closes, it presses down on the push rod, which drives the piston to move within the air groove and compress the spring, increasing the gas pressure within the air groove. The increased gas pressure, through a connecting air passage, pushes the sealing ring to expand and deform towards the contact gap, thereby forming an active airtight seal. This structure utilizes the closing action of the lid to activate the seal, greatly improving the reliability and service life of the seal.

[0009] Preferably, the telescopic assembly includes a connecting rod, a linkage circular plate, and a limiting ring. The linkage circular plate is slidably fitted onto the outside of the hollow column. The two ends of the connecting rod are rotatably connected to the support column and the linkage circular plate, respectively. Movement of the linkage circular plate causes the connecting rod to push and pull the support column to open and close. The limiting ring is fixedly mounted on the connecting rod and, when the support is fully extended, precisely limits the maximum extension range of the connecting rod by abutting against the linkage circular plate or the support column, ensuring that the support angle of the support is at its optimal state.

[0010] Preferably, a foot pad is fixedly installed at the end of the support column away from the hollow column. The foot pad is made of wear-resistant rubber and has deep toothed anti-slip patterns on the bottom surface. Its function is to enhance the friction between the retractable support mechanism and the ground when it is deployed, especially when used on muddy or slippery surfaces, providing reliable anti-slip stability.

[0011] Preferably, a handle is installed in the middle of the outer side wall of the box. The handle is ergonomically designed, and the gripping part is covered with soft, non-slip material, which facilitates the user to carry and move the box by hand without support.

[0012] Preferably, a connecting air passage is provided between the air groove and the mounting groove where the sealing ring is located. The connecting air passage ensures that the gas pressure compressed by the piston in the air groove can be transmitted to the interior of the sealing ring without loss and quickly, thereby efficiently triggering the expansion action of the sealing ring.

[0013] Preferably, the upper surface of the support plate is provided with grooves or anti-slip textures that match the shape of the bottom of the box. The function of the grooves or anti-slip textures is to increase the friction between the support plate and the bottom of the box, preventing the box from sliding or slipping due to accidental collisions or wind when it is raised for support.

[0014] Preferably, the spring is disposed between the piston and the bottom of the air groove. The function of the spring is to provide a restoring force for the push rod and the piston, ensuring that the sealing mechanism can quickly release pressure after the lid is opened, causing the sealing ring to retract to its initial state, facilitating the next closing and sealing.

[0015] Preferably, the sealing ring is a hollow elastic rubber component. The hollow structure gives it good compressibility and expandability, allowing it to expand radially via air pressure and fill the tiny gap between the housing and the lid.

[0016] Preferably, a damping layer or a locking nut is provided between the telescopic column and the hollow column. The function of the damping layer or locking nut is to increase the locking friction of the telescopic column in the extended state or to keep the length of the telescopic column fixed after extension through mechanical locking, so as to avoid accidental retraction under load.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem that existing fishing rod boxes are difficult to place stably in complex outdoor terrain and have no height adjustment by designing a retractable support mechanism at the bottom of the box, including the linkage and cooperation of hollow columns, support columns, telescopic components and telescopic columns. It achieves the technical effect of providing stable off-ground support for the fishing rod box anytime and anywhere, and the support height can be freely adjusted according to the needs of use, which greatly improves the convenience and adaptability of fishing for anglers in the wild environment.

[0019] 2. This utility model, by designing a linkage pneumatic sealing mechanism at the gap between the box body and the box cover, uses the downward pressure when the box cover is closed to push the push rod and piston to compress air, thereby driving the hollow sealing ring to expand and fill the gap. This solves the problem that traditional sealing rings, which rely on static interference fit, are prone to waterproofing failure due to aging deformation or foreign object interference. It achieves active and adaptive tight gap filling, significantly enhances the airtightness and watertightness of the box body after it is closed, and effectively protects the internal fishing gear from moisture and rainwater erosion.

[0020] 3. This utility model solves the problem of inconsistent angles or excessive splitting leading to structural instability in multi-legged supports during deployment by setting a telescopic assembly containing a linkage circular plate, connecting rod, and limiting ring between the support columns. It achieves the technical effect of ensuring that the three sets of support columns can be deployed synchronously and always maintained at the optimal mechanical support angle. The mechanical limiting prevents over-extension, thereby ensuring that the entire support system is subjected to uniform force and has a stable and reliable structure. Attached Figure Description

Detailed Implementation

[0028] 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.

[0029] Example:

[0030] Reference Figures 1 to 5This utility model provides a novel fishing rod box, which aims to solve the structural defects of existing fishing rod boxes that cannot adapt to complex terrain and provide stable support in outdoor fishing scenarios, and that the waterproof sealing performance of the box's closed gaps depends on the degree of rubber aging, leading to sealing failure.

[0031] A novel fishing rod case includes a case body 1 and a lid 2 that covers the opening at the top of the case body 1. The case body 1 is a long, narrow main storage space for holding fishing rods, floats and other fishing gear. The side walls of the case body 1 are provided with buckles 3, which are used to fasten the lid 2 in the closed state to achieve a preliminary mechanical lock on the case body 1. A handle 4 is fixedly installed in the middle of the outer side wall of the case body 1 by screws or rivets, which is used by the user to carry it by hand when it is in storage.

[0032] The bottom of the box 1 is equipped with a retractable support mechanism 5, which can be transformed from a retracted state to an extended support state. The retractable support mechanism 5 is mainly composed of a hollow column 54, a limiting slip ring 55, a support column 52, a telescopic component 53, a telescopic column 56, and a support plate 57. The hollow column 54 serves as the main load-bearing frame and is fixedly installed at the center of the bottom of the box 1. The interior of the hollow column 54 is hollow to accommodate the height adjustment components. The telescopic column 56 is slidably inserted into the interior of the hollow column 54 and can be vertically pulled and moved along the axis of the hollow column 54 to adjust the support height. The support plate 57 is fixedly connected to the top of the telescopic column 56. The upper surface of the support plate 57 is designed with grooves or anti-slip textures that conform to the shape of the bottom of the box 1. When the telescopic column 56 is pushed upward, the support plate 57 is in close contact with the bottom of the box 1, thereby lifting and fixing the box 1.

[0033] On the outside of the hollow column 54, a structure for controlling the opening and closing of the support is provided. The limiting slip ring 55 is slidably fitted on the outer wall of the hollow column 54. The limiting slip ring 55 can slide up and down along the hollow column 54 to limit and lock or release the limit of the retracted state of the support column 52. There are three sets of support columns 52, which are distributed in a circle around the hollow column 54. The top of each set of support columns 52 is rotatably connected to the hollow column 54 through a pivot, so that the support column 52 can be extended outward to form a tripod structure or retracted inward to fit together. The end of the support column 52 away from the hollow column 54, that is, the bottom end, is fixedly installed with a foot pad 51. The foot pad 51 is made of rubber material and is used to provide anti-slip friction when the retracted support mechanism 5 is extended and in contact with the ground, thereby enhancing the stability of the overall support.

[0034] Telescopic components 53 are connected between the support columns 52. The telescopic components 53 include a connecting rod 532, a linkage circular plate 533, and a limiting ring 531. The linkage circular plate 533 is slidably fitted on the lower outer side of the hollow column 54. One end of the connecting rod 532 is rotatably connected to the middle of the support column 52, and the other end is rotatably connected to the linkage circular plate 533. By sliding the linkage circular plate 533 up and down on the hollow column 54, the connecting rod 532 is driven to push and pull the support column 52 to open and close. A limiting ring 531 is fixedly installed on the connecting rod 532. The limiting ring 531 is used to limit the further extension of the connecting rod 532 when the support is fully extended, to prevent the support from excessively splitting and causing structural instability, thereby ensuring that the three sets of support columns 52 always maintain the optimal triangular support shape.

[0035] The sealing mechanism 6 has a set of precisely matched mechanical transmission components, including a sealing ring 65 located at the contact gap between the housing 1 and the cover 2. The sealing ring 65 is made of hollow, highly elastic rubber or silicone material and retracts and hides in the mounting groove on the edge of the housing 1 when not in operation. At the same time, an air groove 64 extending vertically is opened inside the side wall of the housing 1. The air groove 64 serves as the power chamber of the sealing mechanism 6. Its internal space is smooth and has good sealing performance. A connecting air passage is opened between the air groove 64 and the mounting groove where the sealing ring 65 is located to transmit the pressure change in the air groove 64 to the sealing ring 65.

[0036] A piston 62 is slidably installed inside the air groove 64. The outer peripheral wall of the piston 62 is tightly fitted with the inner wall of the air groove 64 to ensure good airtightness. A push rod 61 is fixedly connected to the top of the piston 62. The push rod 61 extends upward through the air groove 64 and extends to the upper surface of the housing 1, so that its top end is exposed at the contact gap between the housing 1 and the cover 2. A spring 63 is provided between the bottom of the piston 62 and the bottom of the air groove 64. The spring 63 is in a naturally extended or slightly compressed state to provide a reset force, so that the push rod 61 maintains an upward pushing tendency when no external force is applied.

[0037] In operation, when the lid 2 is closed onto the body 1 and locked by the latch 3, the lower edge of the lid 2 directly contacts and presses down on the exposed top of the push rod 61. After being pressed, the push rod 61 drives the piston 62 to move downward along the air groove 64. During the downward movement of the piston 62, the spring 63 is continuously compressed, and the air in the closed space at the bottom of the air groove 64 is compressed at the same time, causing the gas pressure in the air groove 64 to increase sharply. The increased air pressure is transmitted to the hollow sealing ring 65 through the connecting air passage, forcing the sealing ring 65 to undergo elastic deformation and expand outward. The expanded sealing ring 65 can actively fill the small and irregular contact gap between the body 1 and the lid 2, thereby forming a tight airtight and watertight barrier. This active sealing structure, which uses mechanical action to convert into air pressure expansion, effectively solves the problem of sealing failure caused by aging or foreign matter inclusion in traditional static rubber rings.

[0038] The dimensions of each component in the sealing mechanism 6 are precisely calculated to ensure that the air pressure generated when the cover 2 is fully closed is sufficient to fully expand the sealing ring 65 without causing it to burst. When the cover 2 is opened, the push rod 61, which has lost its downward pressure, will quickly return to its original position under the rebound force of the spring 63. Negative pressure is generated or released in the air groove 64, causing the sealing ring 65 to automatically retract to its initial state, facilitating the next use cycle.

[0039] As a preferred embodiment, to prevent structural instability caused by excessive opening of the support column 52, the limiting ring 531 on the connecting rod 532 is a ring-shaped protrusion structure. The limiting ring 531 is fixedly sleeved on the end of the connecting rod 532 near the linkage circular plate 533. When the support column 52 extends outward and moves the connecting rod 532 to the preset limit position, the limiting ring 531 will abut against the outer wall of the linkage circular plate 533 or the relevant limiting step, thereby physically blocking the continued extension of the connecting rod 532 and ensuring that the tripod always maintains the triangular support form with optimal mechanical performance. The foot pad 51 fixedly installed at the bottom of the support column 52 adopts a widened design, and the bottom surface of the foot pad 51 is molded with deep tooth anti-slip texture. The material of the foot pad 51 is wear-resistant and has a certain degree of elasticity. It can provide sufficient friction and also play a buffering and protective role against the impact force when the support column 52 lands.

[0040] As a preferred embodiment, the handle 4 installed on the side wall of the box 1 adopts an ergonomic design. The gripping part of the handle 4 is covered with a soft, non-slip rubber sleeve, and the handle 4 is connected to the fixed base through a pivot, so that it can be folded down and fits against the surface of the box 1 when not in use, reducing the storage volume and preventing snagging during transportation.

[0041] As a preferred embodiment, the air passage connecting the air groove 64 and the sealing ring 65 is designed to be as short and straight as possible to reduce airflow resistance. At the same time, one or more O-rings can be added to the outer wall of the piston 62 to further improve the dynamic sealing performance between the piston 62 and the inner wall of the air groove 64, ensuring that the pressure generated by the push rod 61 can be converted into the expansion force of the sealing ring 65 to the greatest extent. The spring 63 is a fatigue-resistant high-strength stainless steel spring 63, and its surface is treated with anti-rust to prevent corrosion and breakage caused by humid environment. At the same time, the connection between the push rod 61 and the piston 62 adopts thread fastening and adhesive application process to prevent loosening and falling off during frequent reciprocating motion.

[0042] In one preferred embodiment, in addition to the anti-slip texture, the upper surface of the support plate 57 can also be provided with a positioning groove according to the specific shape of the bottom of the box 1, so that the box 1 can be embedded in the groove to achieve self-locking when placed on the support plate 57, or an upward baffle structure can be added to the edge of the support plate 57 to restrict the horizontal displacement of the box 1 in all directions.

[0043] The implementation principle of this application embodiment is as follows: the box body 1 is a long strip-shaped main storage space, the box lid 2 is closed at the upper opening of the box body 1, and the box lid 2 is fastened by the buckles 3 distributed on the side wall of the box body 1 to achieve initial closure. The handle 4 is installed in the middle of the outer side wall of the box body 1 for the user to carry by hand.

[0044] When the fishing rod box needs to be used temporarily as a support, the retractable support mechanism 5 unfolds from the bottom of the box 1. The limiting slip ring 55 located on the outside of the hollow column 54 slides upward, releasing the retraction limit on the support column 52. The support column 52 unfolds outward around the hollow column 54. At the same time, the telescopic component 53 moves synchronously. The connecting rod 532 drives the linkage circular plate 533 to unfold, so that the three sets of support columns 52 maintain a stable triangular support shape. The limiting ring 531 limits the extension range of the connecting rod 532 to avoid over-extension. The telescopic column 56 stretches upward from inside the hollow column 54 to adjust the overall height of the support. The support plate 57 is connected to the top of the telescopic column 56 and contacts the bottom of the box 1. Finally, the support is fixed to the ground through the foot pad 51 at the bottom of the support column 52.

[0045] After the lid 2 is closed, the sealing mechanism 6 enhances the waterproofness of the box body 1. The sealing ring 65 is pre-installed in the contact gap between the box body 1 and the lid 2. When the buckle 3 is engaged, the lid 2 pushes the push rod 61 downwards. The push rod 61 pushes the piston 62 to move along the air groove 64. When the piston 62 moves, it compresses the spring 63. At the same time, the gas pressure in the air groove 64 increases, pushing the sealing ring 65 to expand into the gap and fill the contact gap between the box body 1 and the lid 2. When the lid 2 is opened, the spring 63 returns to its original position, driving the piston 62 and the push rod 61 back to their original positions. The sealing ring 65 returns to its initial state, completing the sealing and reset cycle. The entire fishing rod box not only achieves convenient storage of fishing rods, but also provides temporary support through the bracket mechanism. At the same time, the sealing mechanism 6 enhances the waterproofness, adapting to the multiple needs of fishing scenarios.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
