Description

TECHNICAL FIELD

[0001] The utility model belongs to fishing tackle technical field, specifically relates to a kind of through hydraulic adjustment's fishing platform telescopic foot. BACKGROUND

[0002] Fishing platform is an auxiliary fishing gear, is specially provided for wild fishing leisure lovers to encounter complex terrain also can quickly build up flat comfortable to place fishing box operation platform.Fishing platform is generally used more when reservoir fishing, since its convenient to carry foldable, four legs can freely extend and retract, and the distance can be adjusted relatively far, and adaptability is also very strong.Fishing platform can make fishing position farther when not suitable for short rod fishing.Fishing platform material is generally aluminum alloy, more solid and durable, and rust and corrosion resistant.

[0003] Most of the existing fishing platforms can already realize height adjustment, such as adjusting the height of the fishing platform through a hand crank device, the traditional hand crank device uses a worm gear or a planetary gear transmission, and the transmission ratio is generally locked in the range of 3:1 to 5:1. Taking a fishing platform with a typical stroke of 1 meter as an example, the operator needs to turn the crank 30-50 times to complete the full stroke adjustment, and the effective stroke per circle is only 20-33 mm, resulting in more than 3 minutes of time consumption per adjustment, and the operator's physical exertion is equivalent to lifting a 20 kg weight 10 times. Such design has failed to meet the demand for quick response in modern fishing scenarios. For example, the unfolding and locking of the folding fishing platform relies on spring pins or buckle mechanisms, and their resistance to lateral shear is generally less than 200 N, which is not stable. Alternatively, other multi-structure combinations can be used, such as providing a fine adjustment device on the fishing platform leg to achieve fine adjustment of the height of the fishing platform, but these methods often cannot be adjusted in real time during use, and the adjustment process still needs to rely on the operator's sense of touch to determine whether the adjustment is complete, but whether the adjustment is complete still needs to be tried multiple times. In addition, due to insufficient light or underwater visual interference, the height setting is prone to deviation, and the complexity of these structures poses multiple challenges in actual field environments, such as sand intrusion, corrosion effects, temperature sensitivity, etc., which often shortens the service life of the product.

[0004] Based on the above-mentioned problems of existing fishing platforms, such as inability to adjust in real time during use, low adjustment efficiency and short service life, a fishing platform telescopic foot adjusted by hydraulic pressure is proposed. UTILITY MODEL CONTENTS

[0038] The specific implementation of the utility model will be described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0039] Example 1:

[0040] In combination with Figures 1 to 6 the figure, the fishing platform telescopic foot of the embodiment is adjusted by hydraulic pressure and comprises a foot body 200, a lower support rod 1 and a lifting rod 2, the lifting rod 2 is sleeved on the upper part of the lower support rod 1, and the relative position of the lifting rod 2 on the lower support rod 1 is adjusted to realize the adjustment of the overall height of the foot body 200;

[0041] The inside of the lifting rod 2 is provided with a hydraulic adjusting assembly 3, which includes a liquid injection and discharge mechanism 31 arranged at the top of the lifting rod 2, and a sliding plug 32 that can move up and down in the pipe of the lifting rod 2 through hydraulic adjustment. The bottom of the sliding plug 32 abuts against the top of the lower support rod 1, which ensures sufficient bearing capacity. The bottom of the lower support rod 1 is also provided with a conventional claw-shaped or other shaped base for fixing to the ground. The top end of the lower support rod 1 is sleeved with the lifting rod 2, which can freely adjust the up-down position as needed, thereby adjusting the height of the fishing platform telescopic foot, so that the user can adapt to different water surface heights and terrain conditions. The inside of the lifting rod 2 is provided with a hydraulic adjusting assembly 3 for adjusting the height of the fishing platform. The hydraulic adjusting assembly 3 allows the user to adjust the extension length of the lifting rod 2 by controlling the hydraulic pressure, thereby adjusting the height of the fishing platform. In this embodiment, a portable water pump or other device is used as a liquid injection device 300. In the illustration, only one water injection nozzle is used for illustration, that is, a water injection and pressurization method is used as the hydraulic driving force. The liquid injection and discharge mechanism 31 is arranged at the top of the lifting rod 2 and is responsible for controlling the inflow and outflow of water. The user can apply or release hydraulic pressure by operating a valve or similar device. The liquid injection and discharge mechanism 31 is designed with a leak-proof seal to ensure that no water leaks during adjustment, maintaining the stability and safety of the system.

[0042] That is, through the arrangement of the hydraulic adjusting assembly 3, liquid can be injected and discharged at the liquid injection port, so that the lifting rod is elongated or shortened relative to the lower support rod, thereby adjusting the height of the fishing platform. This effectively solves the problem that the existing fishing platform cannot be adjusted in one time in some places where the ground is not very flat, and needs to be adjusted multiple times, which is troublesome and time-consuming. Or during fishing, if the adjustment cannot be made in time, it will also affect the fishing experience. Therefore, the technical solution of the present embodiment can achieve the effect of instant adjustment. During the adjustment process, the user can also stay on the fishing platform without getting off, which is not achievable by the prior art.

[0043] The lifting rod 2 includes a rod body 21 and a hydraulic mounting seat 22 arranged at the top of the rod body 21. The upper part of the hydraulic mounting seat 22 is provided with a liquid injection port 23. The liquid injection and discharge mechanism 31 is arranged in the hydraulic mounting seat 22, and the opening and closing control of the liquid injection port 23 is realized through the liquid injection and discharge mechanism 31. The liquid injection and discharge mechanism 31 includes a sealing plug 314, a guide rod 313 and a fixed seat 311 arranged in sequence. The fixed seat 311 is fixed with the hydraulic mounting seat 22;

[0044] As Figure 3As shown, the guide rod 313 is sleeved with a spring member 315, one end of the spring member 315 abuts against the upper part of the fixed seat 311, and the other end of the spring member 315 abuts against the bottom of the sealing plug 314. The guide rod 313 serves as a guide and support structure for the sealing plug 314, ensuring the stable movement of the sealing plug 314 in the vertical direction. The main function of the spring member 315 is to provide a restoring force, so that the sealing plug 314 can automatically return to the initial position when not subjected to external force. This ensures that the liquid injection and drainage mechanism 31 has good responsiveness and stability during operation. The fixed seat 311 is provided with at least one opening 312 for liquid flow. The fixed seat 311 provides a safe and efficient passage for water flow.

[0045] The sealing plug 314 is used for sealing the liquid injection port 23 to prevent liquid leakage when not in use. Through the liquid injection port 23, the user can conveniently introduce or release liquid; when injecting liquid, the liquid pressure overcomes the spring force of the spring member 315 to press down the sealing plug 314, thereby injecting liquid into the lifting rod 2 through the liquid injection port 23.

[0046] The sliding plug 32 is located inside the lifting rod 2, and the bottom of the sliding plug 32 abuts against the top of the lower support rod 1. When the liquid injection and drainage mechanism 31 introduces or releases hydraulic pressure, the sliding plug 32 will move up and down according to the change in the amount of injected water, pushing or pulling the lifting rod 2 to elongate or shorten relative to the lower support rod 1. When the user applies pressure to the sealing plug 314, the sealing plug 314 will move downward along the guide rod 313, thereby compressing the spring member 315 and triggering the water flow control mechanism, such as opening or closing a valve. The sealing plug 314 is used to ensure effective prevention of liquid leakage in the closed state. Specifically, the outer periphery of the sealing plug 314 is provided with a first sealing groove 316, and the first sealing groove 316 is provided with a first sealing ring 317. The first sealing groove 316 is an annular groove on the outer periphery of the sealing plug 314, and the first sealing groove 316 is used to accommodate and fix the first sealing ring 317. The first sealing groove 316 ensures that the first sealing ring 317 can tightly fit between the sealing plug 314 and the adjacent components, forming an effective seal.

[0047] The first sealing ring 317 is installed in the first sealing groove 316, and when the sealing plug 314 moves on the guide rod 313, the first sealing ring 317 will be tightly pressed between the adjacent components, effectively preventing liquid leakage. The first sealing ring 317 can maintain its elasticity and shape stability during long-term use, ensuring good sealing effect even under high hydraulic pressure or frequent operation.

[0048] In combination Figure 4As shown, the water inlet end of the liquid injection port 23 gradually decreases in diameter from outside to inside, and the water outlet end of the liquid injection port 23 gradually expands in diameter from outside to inside, i.e., the overall structure is similar to a sandglass. In order to fit this shape, the first sealing ring 317 is integrally provided as a tapered shape, and forms an effective seal under the action of the spring member 315.

[0049] Specifically, the water inlet end of the liquid injection port 23 gradually decreases in diameter from outside to inside, which helps to guide the water flow more concentratedly into the liquid injection port 23, reduces the diffusion and splashing of the water flow, and improves the utilization efficiency of the water flow. The gradually decreasing diameter increases the speed and pressure of the water flow, which helps to quickly and effectively introduce liquid when needed.

[0050] On the contrary to the water inlet end, the water outlet end of the liquid injection port 23 gradually expands in diameter from outside to inside, which helps to smoothly disperse the water flow when it leaves the liquid injection port 23, avoiding the phenomenon of local high pressure and scouring caused by too concentrated water flow. The gradually expanding diameter slows down the speed of the water flow and reduces the impact force of the water flow, which helps to improve the uniformity and stability of the water flow and ensures the smooth flow of the water flow in the entire mechanism.

[0051] In combination Figure 6 As shown, the outer periphery of the sliding plug 32 is sequentially provided with a first wear-resistant groove 321, a second sealing groove 322, and a second wear-resistant groove 323 from top to bottom, and the first wear-resistant ring 324, the second sealing ring 325, and the second wear-resistant ring 326 are sleeved on the first wear-resistant groove 321, the second sealing groove 322, and the second wear-resistant groove 323. The first wear-resistant ring 324 and the second wear-resistant ring 326 are both circular rings of the same structure, and the second sealing ring 325 is a Y-shaped ring.

[0052] Specifically, the sliding plug 32 plays a crucial role in ensuring the sealing and stability of the entire mechanism. The first wear-resistant groove 321, the second sealing groove 322, and the second wear-resistant groove 323 are sequentially provided on the outer periphery of the sliding plug 32 from top to bottom, and the first wear-resistant ring 324, the second sealing ring 325, and the second wear-resistant ring 326 are sleeved on these sealing grooves.

[0053] The first wear-resistant groove 321 is located at the top of the sliding plug 32, ensuring that the first wear-resistant ring 324 can be installed and fitted between the inner wall of the sliding plug 32 and the adjacent component such as the lifting rod 2. The first wear-resistant ring 324 is a circular ring of the same structure made of elastic material such as rubber or silicone, which has good elasticity and wear resistance. It can effectively prevent liquid from leaking from the small gap between the sliding plug 32 and the lifting rod 2, thereby ensuring the accuracy and stability of the hydraulic adjustment.

[0054] The second sealing groove 322 is located below the first wear-resistant groove 321 and is adapted to the special shape of the second sealing ring 325, a Y-shaped ring. Not only does it increase the area of the sealing surface, but it also improves the sealing effect. The two sides of the Y-shaped ring can more closely fit the contact surface between the sliding plug 32 and the adjacent components, maintaining good sealing performance even in high-pressure or high-frequency vibration conditions. In addition, the Y-shaped design also helps to disperse pressure, reducing the wear of the sealing ring and prolonging its service life.

[0055] The second wear-resistant groove 323 is located at the bottom of the sliding plug 32 and, like the first wear-resistant groove 321, ensures that the second wear-resistant ring 326 can be securely installed and fit between the sliding plug 32 and the lower support rod 1 or other adjacent components. The second wear-resistant ring 326 is also a circular ring with the same structure, made of the same elastic material as the first wear-resistant ring 324. It can effectively prevent liquid from leaking from the small gap between the sliding plug 32 and the lower support rod 1, further enhancing the sealing and stability of the entire mechanism.

[0056] The outer wall of the hydraulic mounting seat 22 is coated with fluorescent paint, which is a special paint that can emit bright light in dark or low-light environments. It is still clearly visible at night or in low light, providing clear visual indications for users and serving as a safety protection effect.

[0057] Example 2:

[0058] Compared with Example 1, in combination with the drawings shown in Figure 4 and Figure 6 , the lower support rod 1 also has an elastic member 4, which has a limiting protrusion 5 passing through the side wall of the lower support rod 1, and a limiting hole 26 is opened in the side wall near the bottom of the lifting rod 2. When the limiting protrusion 5 and the limiting hole 26 are matched and inserted, the position between the lower support rod 1 and the lifting rod 2 is fixed. The elastic member 4 is provided with a limiting block 5 matched with the limiting hole 26. The limiting block 5 is matched with the limiting hole 26 on the lifting rod 2. The limiting block 5 ensures smooth insertion and removal of the limiting hole 26, and the elastic member 4 is a U-shaped metal spring.

[0059] When the sliding plug 32 moves to the bottom, the limiting block 5 will accurately insert into the limiting hole 26, thereby limiting the further movement of the sliding plug 32, achieving the effect of limiting. This design not only improves the positioning accuracy and stability of the mechanism, but also prevents malfunctions caused by misoperation.

[0060] The above is only a preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, without departing from the technical principles of the present application, a number of improvements and refinements can be made, which should also be considered within the protection scope of the present application.
