Description

Technical Field

[0001] The utility model belongs to the technical field of outrigger positioning structures, and in particular relates to an outrigger positioning structure and a fishing platform with the positioning structure. Background Art

[0002] The outriggers provided on the fishing platform can provide a stable supporting effect for the fishing platform, and the existing outriggers are mostly fixed in a tightly hugging structure.

[0003] The Chinese utility model patent with announcement number CN210290380U discloses a table height adjustment locking device, which can be locked at different heights of the legs, thereby realizing the change of the table height. However, the locking member is an integrated structure with an opening on one side. Its overall structure is complex and it is a special-shaped part. The cost and difficulty of mold opening and processing are relatively high. Its clamping or loosening requires its own toughness to deform. Long-term repeated bending will cause aging and loss of toughness. Even with the elastic support of the compression spring, it is difficult to open and close smoothly. When the legs are inserted and pulled out axially, it is not smooth and difficult to pull the legs smoothly. What's more, it is placed in the mounting hole, and it is even more difficult for the locking member to loosen and open naturally, and the operation is not flexible.

[0004] Moreover, there is a large gap between the two assembly parts extending outward to place the compression spring, and the eccentric locking rod is used to achieve the opposite locking of the two. The biggest problem with this structure is that after long-term use, one or both assembly parts will be deformed and bent due to the lack of effective contact support, and will be torn and damaged over time and lose the locking function. In addition, the position of the locking rod hole also needs to correspond precisely to the other hole positions, otherwise it is difficult to assemble the legs normally, which increases the difficulty of processing.

[0005] The Chinese utility model patent with publication number CN218151851U discloses a fishing platform adjustment lock, which is also an integrated structure with one side opening and is also provided with two branches, which can clamp legs of different diameters. However, its loosening and opening action is also achieved by its own toughness deformation. Although there is no need to reserve space for the compression spring, there is a gap between the two branches when clamping the thicker legs. After repeated tightening, the two branches are still prone to tearing and deformation due to stress. Moreover, in order to achieve the functions of clamping and loosening, not only a certain toughness requirement is imposed on the material, but also the thickness cannot be too thick, otherwise it will be difficult to deform. These all restrict the service life and processing difficulty of the locking parts.

[0006] In addition, the Diaoyutai is used outdoors, and exposure to sunlight, rain and other environments can easily cause aging and deformation of fasteners (or locking parts), affecting normal use. Utility Model Content

[0007] The utility model aims to solve the technical problems in the prior art that the leg fixing parts have a complex structure, are easy to damage and are not flexible to pull out, and to provide a leg positioning structure and a fishing platform with the positioning structure to improve the current shortcomings.

[0008] In order to achieve the above objectives, on the one hand, the utility model provides a leg positioning structure, comprising:

[0009] Two holding parts are hinged to each other to swing towards each other or away from each other;

[0010] The wrapping parts are respectively arranged on the opposite sides of the two holding members and wrap around the outer periphery of the supporting legs;

[0011] as well as,

[0012] The locking mechanism is arranged at one end of the two clamping members away from the hinge to achieve locking or loosening of the supporting legs.

[0013] As a further improvement of the present invention, the two clamping members are respectively provided with a force-bearing portion at one end away from the hinge, and each of the force-bearing portions is provided with a locking hole that passes through both ends and is coaxially corresponding to each other.

[0014] As a further improvement of the utility model, the locking mechanism includes a fastener penetrating the locking hole, one end of the fastener extends out of a clamping member and is hinged to an eccentric locking rod, and the other end of the fastener is threadedly connected to a locking member provided on another clamping member.

[0015] As a further improvement of the present invention, the surface where the wrapping portion fits the outer periphery of the leg is in an inclined structure that deviates from the vertical axis.

[0016] As a further improvement of the present invention, limiting holes for embedding elastic parts are respectively provided at corresponding positions of the two force-bearing parts.

[0017] On the other hand, the utility model provides a fishing platform with the positioning structure, including the above-mentioned leg positioning structure and a platform, wherein a plurality of positioning holes penetrating the thickness direction of the platform are evenly arranged near the edge.

[0018] As a further improvement of the present invention, the diameter of the positioning hole is larger than the diameter of the supporting leg.

[0019] As a further improvement, the bottom surface of the platform is provided with a receiving cavity which is communicated with the positioning hole, and the receiving cavity is provided with an assembly hole for embedding the positioning mechanism.

[0020] As a further improvement of the utility model, the platform includes two mutually symmetrical split platforms, a first split platform and a second split platform, and corresponding sides of the first split platform and the second split platform are movably hinged.

[0021] As a further improvement, the outer peripheral corners of the platform are arc-shaped rounded corner structures.

[0022] After adopting the above technical solution, the utility model has the following technical effects:

[0023] The utility model has a simple structure, low processing difficulty and cost, and improves the market competitiveness of the product. Since the two clamping parts are connected by hinged connection, they do not need to rely on their own toughness to deform and are not easy to be damaged. At the same time, when the locking mechanism is released, the two clamping parts can be naturally loosened instantly and lose the clamping force. In addition, the hinged connection allows the legs to be quickly and smoothly pulled out, making it more flexible and labor-saving to use.

[0024] In addition, because the diameter of the positioning hole is larger than the diameter of the leg, even if the clamping piece cannot be loosened smoothly due to an accident, the axial displacement can occur by axially pushing the leg, and the limiting blocking effect of the positioning hole can be utilized to separate the two clamping pieces from each other, so that the leg can be pulled out smoothly. Compared with the existing elastic clamping structure, the leg is easier to pull out smoothly, is not easy to be damaged, and has a longer service life.

[0025] The two force-bearing parts are in a nearly fitted state, with a small gap and a larger force-supporting area, so they are not easily torn and damaged when repeatedly tightened. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the following Figures 1 to 8 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Embodiment 1

[0040] Reference Figures 1 to 8 The utility model provides a leg positioning structure, including two holding members 301, which are preferably mirror-symmetrical structures, and their common ends are hinged to each other (refer to Figure 7 and Figure 8 After the hinge point 303 is formed, the legs 200 can be swung together or away from each other. In layman's terms, the two can be clamped in opposite directions or separated in opposite directions, thereby clamping the legs 200.

[0041] Compared with the traditional toughness deformation clamping structure, this structure not only reduces the processing difficulty, but also can quickly change the clamping and loosening, and use the smooth pulling of the legs to control the platform height. The traditional clamping parts are plastic parts. When loosening, they need to rely on their own toughness to rebound. Although there are compression springs to assist, in the outdoor open air environment, the clamping parts will age and lose their toughness over time, especially when loosening and disassembling the legs, they are difficult to pull and inflexible. This structure is conducive to the hinged structure. When the clamping force is lost, the two clamping parts 301 can instantly lose the clamping force and loosen naturally, and there is no need to meet the toughness requirements. The overall structure is a symmetrical and simple structure, which is not a special-shaped part. It has low processing difficulty and cost, is not easy to damage, and has a prolonged service life.

[0042] There is also a wrapping portion 302, which is respectively arranged on the opposite side of the two holding members 301 and wraps around the outer periphery of the leg 200. The wrapping portion 302 and the holding member 301 are an integral structure, and its shape can be determined according to the shape of the leg, such as a semicircular arc or a semi-square.

[0043] Of course, in order to better hold, its specific size is better not to be a complete semicircular arc or semi-square, so that the channel 304 formed when the two are merged opposite to each other is not a complete circle or a complete square. When holding the leg 200, the opposite sides of the two holding parts 301 will not be completely fitted and connected, but a very small gap will be left. This gap is to achieve a better and dense fit on the outer peripheral surface of the leg 200 to prevent the two holding parts 301 from losing the continuous holding force (or clamping force) on the leg 200 after they are fully fitted.

[0044] On the basis of the above structure, the surface of the wrapping portion 302 that fits the outer periphery of the leg 200 is in an inclined structure that deviates from the vertical axis. In other words, after being wrapped, the leg 200 is in an attitude that deviates from the vertical axis, so that the bottom end of the leg can be tilted outward and the top end can be tilted inward, commonly known as the outward eight-character attitude. When the bottom ends of the four legs 200 are all tilted outward, the stable support effect of the platform 100 can be greatly improved.

[0045] In addition, the locking mechanism 400 is arranged at one end of the two holding members 301 away from the hinge to achieve locking or loosening of the leg 200. When the locking mechanism 400 is tightened, the two holding members 301 will gradually move toward each other to apply a holding force to the leg 200. Otherwise, no holding force is applied to the leg 200.

[0046] As a further improvement of the present invention, the two clamping members 301 are respectively provided with a force-bearing portion 305 at one end away from the hinge, and the height direction of the force-bearing portion 305 and the clamping member 301 (see Figure 7 and Figure 8The height direction shown in the figure is consistent, and it is also an integrated structure with a large force-bearing area. The distance between the two opposite sides is very small. Compared with the thinner assembly part in the prior art, the support effect is qualitatively improved. Moreover, the structure is an integrated design, which is also easy to process and shape, and is not easy to tear and damage. Each of the force-bearing parts 305 is provided with a through-hole at both ends ( Figure 7 and Figure 8 The height direction shown in FIG. 1 is a height direction of the locking holes 3051 and the locking holes 3051 are coaxially corresponding to each other.

[0047] When locked, the two force-bearing parts 305 can provide good and stable support, and can disperse the force to each clamping member 301 as a whole, rather than being limited to the force-bearing position (for details, please refer to the contents shown in the drawings in the prior art). Compared with the assembly part of the prior art, it has a longer service life and is less prone to damage and deformation.

[0048] refer to Figure 8 The specific structure of the locking mechanism 400 in this embodiment is as follows: the fastener 401 that passes through the locking hole 3051 is a columnar structure that can be movably inserted into the locking hole 3051, and one end of the fastener 401 extends out of the holding member 301 and is hinged (see Figure 8 The hinge point 2 (405) is an eccentric locking rod 402, and the eccentric locking rod 402 can drive the fastener 401 to rotate axially. The other end of the fastener 401 is threadedly connected with a locking member 403 provided on another clamping member, and the locking member 403 can be a nut.

[0049] When the eccentric locking rod 402 is turned, the fastener 401 rotates axially and is threadedly connected with the locking member 403 to achieve a tightening effect. On the contrary, it is a loosening effect. The locking member 403 is embedded in the groove of the clamping member 301 and will not rotate axially. After locking, the eccentric portion of the eccentric locking rod 402 is used to contact the surface of the clamping member 301 or the surface of the pad 404 to achieve a locking effect, and the leg 200 can be firmly fixed.

[0050] The pad 404 is disposed at a position close to the eccentric locking rod 402 to prevent slipping and loosening caused by direct contact with the clamping member 301 .

[0051] In order to further improve the quick release effect of the two clamping members 301, the corresponding positions of the two force-bearing parts 305 are respectively provided with limiting holes 3052 for embedding elastic members 3053. The elastic members 3053 are preferably compression springs, which are mainly used for reverse contact with the clamping members 301, and together with the hinged manner, they can achieve the purpose of quickly opening and releasing the legs 200. Embodiment 2

[0052] refer to Figures 1 to 8The present embodiment provides a fishing platform, including the above-mentioned outrigger positioning structure 300 and a platform 100. The platform 100 is evenly provided with a plurality of positioning holes 1031 that penetrate the thickness direction thereof near the edge. The positioning holes 1031 are arranged near the edge in order to achieve the purpose of not exposing the outrigger positioning mechanism 300. If it is exposed, it may be scratched and loosened, which is dangerous.

[0053] Moreover, the diameter of the positioning hole 1031 is slightly larger than the diameter of the leg 200. The size difference is to facilitate the movement of the leg 200 to a certain extent and to facilitate quick assembly and alignment without causing obvious shaking during use. This structure is adopted so that once the leg 200 is difficult to loosen, the leg 200 can be moved in the axial direction to achieve a certain small swing of the leg 200 under the limit of the positioning hole 1031, thereby facilitating the reverse separation of the two clamping parts 301. If the diameter of the positioning hole 1031 is the same as the diameter of the leg 200, the leg 200 cannot be axially offset, and it is difficult to pull out the leg 200 under special circumstances. Secondly, the larger diameter positioning hole 1031 also facilitates the insertion of the leg, preventing the situation where it is difficult to align the hole position.

[0054] The bottom surface of the platform 100 is provided with a receiving cavity 103 that is connected to the positioning hole 1031. The receiving cavity 103 is provided with an assembly hole 1033 for embedding the positioning mechanism. The receiving cavity 103 is arranged on the bottom surface for better hidden placement, rather than exposed, so that there will be no accidental contact during use. In addition, the receiving cavity 103 is arranged on the bottom surface of the platform, which is not exposed and beautiful. In practice, the receiving cavity 103 can be evenly arranged at the four corners of the square platform 100. Of course, the shape of the platform 100 is not only square. No matter what shape it is, the receiving cavity 103 needs to be evenly distributed to ensure the stability of the load.

[0055] Specifically, the leg positioning mechanism 300 can be directly inserted into the accommodating cavity 103 through the assembly hole 1033. The accommodating cavity 103 is inserted in the horizontal lateral direction, so that a good supporting effect can be achieved. When a person stands on the platform 100, the force will be dispersed to the whole through the accommodating cavity 103, preventing the leg positioning mechanism 300 from being loosened due to excessive force. In addition, a reinforcing rib 1032 is provided between the accommodating cavity 103 and the platform 100, which can provide a better supporting effect on the force-supported part and extend the service life.

[0056] In actual use, in order to better fix the leg positioning mechanism 300, one of the clamping parts 301 can be fastened to the accommodating cavity 103 by using self-tapping screws, so that one clamping part 301 is fixed and the other clamping part 301 swings relatively. In the prior art, it is necessary to drill holes on the surface of the profile, and the position of the hole needs to accurately correspond to other parts to achieve alignment and assembly, which makes the processing difficult. This structure does not require drilling additional holes, and only needs to insert the leg positioning mechanism 300 into the accommodating cavity 103. In addition, the diameter of the positioning hole 1031 is slightly larger, so it is very convenient to assemble. When in use, the force direction of the fishing platform is vertical, and the accommodating cavity 103 is horizontally plugged in. The two do not interfere with each other and can achieve a good supporting effect.

[0057] In addition, for the convenience of carrying, the platform 100 includes two mutually symmetrical split platforms 1 101 and 102, and the corresponding sides of the split platforms 101 and 102 are movably hinged to realize the opposite folding and storage of the two. Moreover, the bottom surface of the platform 100 is also provided with a clip for the legs 200, and all accessories of the fishing platform after storage are placed inside it, which is convenient for carrying.

[0058] The outer corners of the platform 100 in this embodiment are arc-shaped, that is, the four corners are not sharp spliced ​​corners, but are rounded corners, which can greatly improve safety. Even if a person accidentally touches it, he will not be injured. In addition, after adopting the rounded corner shape, the periphery is an integral structure without splicing gaps, which is more beautiful and durable.

[0059] After adopting the above technical solution, the utility model has the following technical effects:

[0060] The utility model has a simple structure, low processing difficulty and cost, and improves the market competitiveness of the product. Since the two clamping parts are connected by hinged connection, they do not need to rely on their own toughness to deform and are not easy to be damaged. At the same time, when the locking mechanism is released, the two clamping parts can be naturally loosened instantly and lose the clamping force. In addition, the hinged connection allows the legs to be quickly and smoothly pulled out, making it easier and more labor-saving to use.

[0061] In addition, because the diameter of the positioning hole is larger than the diameter of the leg, even if the clamping piece cannot be loosened smoothly due to an accident, the axial displacement can occur by axially pushing the leg, and the limiting blocking effect of the positioning hole can be utilized to separate the two clamping pieces from each other, so that the leg can be pulled out smoothly. Compared with the existing elastic clamping structure, the leg is easier to pull out smoothly, is not easy to be damaged, and has a longer service life.

[0062] The two force-bearing parts are in a nearly fitted state, with a small gap and a larger force-supporting area, so they are not easily torn and damaged when repeatedly tightened.

[0063] refer to Figure 7 and Figure 8 The holding part 301, the wrapping part 302 and the force-bearing part 305 in the utility model are integrated, the overall structure is simple, the processing cost is low without any special shape, and the hinged connection can be quickly loosened. It has high load-bearing capacity, quick assembly and convenient use.
