[0025] A rod holder is an important auxiliary tool for both hand and sea rod fishing. Its purpose is to support the fishing rods and set them up on the bank of the fishing area. The main benefits of using a rod holder are: first, it reduces the angler's physical exertion, as anglers easily become fatigued from holding the rod for extended periods; second, it allows for the monitoring of multiple rods simultaneously, thus improving fishing efficiency; and third, some fishing methods, such as sea rod fishing, require a rod holder. A rod holder typically consists of a rod fork and a rod support. Accessories such as the rod fork and alarm need to be easily and securely installed on the rod support, and allow for quick assembly, disassembly, and angle adjustment as needed. Currently, the most common connection methods for accessories on the market are threaded connections and magnetic connections.
[0026] When using threaded connections, each installation requires tightening screws to secure the parts, which is not only cumbersome and time-consuming, but also extremely inconvenient as adjusting the angle or position of the parts after installation necessitates loosening and tightening the screws again. Furthermore, frequent tightening can cause thread wear, affecting long-term reliability. While magnetic connections offer some ease of installation and disassembly, their connection strength and resistance to vibration and impact are weak. Parts are prone to loosening under external forces or equipment vibration, posing a safety hazard, and are particularly unsuitable for fishing environments where stability is critical.
[0027] In other words, some existing connection methods involve cumbersome and time-consuming operations, while others have poor reliability and stability.
[0028] Based on this, please refer to Figure 1 and Figure 6 The support plug structure 100 provided in the embodiments of this utility model can effectively improve the aforementioned technical problems. This support plug structure 100 can achieve quick assembly and disassembly of the support plug 120 while ensuring the reliability and stability of the connection, and its structure is simple. This support plug structure 100 is used in the support frame 1000, and devices and mechanisms having this support plug structure 100 have the same functions as described above, which will not be elaborated further here.
[0029] Figure 1 This is a schematic diagram of the extended state of the support frame 1000 provided in an embodiment of this utility model; Figure 2 This is a schematic diagram of the folding process of the support frame 1000 provided in the embodiment of this utility model; Figure 3 This is a schematic diagram of the folded state of the support frame 1000 provided in an embodiment of this utility model.
[0030] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, the support frame 1000 includes a main crossbeam 200, a support bracket 300, a vertical tube 400, multiple leg tubes 500, and at least one support plug structure 100. One end of the vertical tube 400 is rotatably connected to the main crossbeam 200, and the other end of the vertical tube 400 is connected to the support bracket 300. The support bracket 300 is connected to the fixed base 110. The multiple leg tubes 500 are evenly distributed at both ends of the main crossbeam 200, and each leg tube 500 is rotatably connected to the main crossbeam 200. The support plug structure 100 is used for detachable connection with support accessories such as support forks, alarms, etc. By setting the vertical tube 400 to be rotatably connected to the main crossbeam 200, and the leg tubes 500 to be rotatably connected to the main crossbeam 200 evenly, when the support frame 1000 is not needed, the vertical tube 400 and the leg tubes 500 can be rotated to be close to the main crossbeam 200, so that they are folded and nearly parallel to the main crossbeam 200, thereby reducing the volume of the support frame 1000 after folding, making it convenient to carry and transport.
[0031] Figure 4 This is an exploded view of a portion of the support frame 1000 provided in an embodiment of this utility model. Please continue reading. Figures 1-3 and combined Figure 4 Optionally, the support frame 1000 in this embodiment further includes an upper base 810, a lower base 820, and a vertical tube rotating seat 830. The upper base 810 is fixedly connected to the main crossbeam 200, the vertical tube rotating seat 830 is movably connected to the upper base 810, and the vertical tube 400 is connected to the vertical tube rotating seat 830. The vertical tube rotating seat 830 rotates relative to the upper base 810, which can drive the vertical tube 400 to rotate, moving it closer to or away from the main crossbeam 200. The lower base 820 is fixedly connected to the main crossbeam 200, and the foot tube 500 is movably connected to the lower base 820, that is, the foot tube 500 can rotate relative to the lower base 820, moving it closer to or away from the main crossbeam 200.
[0032] Specifically, in this embodiment, the upper base 810 is connected to the lower base 820 and the vertical tube rotating seat 830 respectively by bolts or other threaded fasteners. To ensure the reliability of the connection between the vertical tube rotating seat 830 and the upper base 810, as well as the stability of rotation, the upper base 810 in this embodiment has a mounting groove.

Optionally, in this embodiment, the lower base 820 is sleeved on the main crossbeam 200 and is fixedly connected to the main crossbeam 200 by rivets or other threaded fasteners.
[0033] Optionally, the support frame 1000 in this embodiment further includes a leg tube plug 840, through which the leg tube 500 is connected to the lower base 820. The leg tube plug 840 is connected to the leg tube 500 by fasteners such as rivets, and is movably connected to the lower base 820. To limit the angle of the leg tube 500 when it is retracted, a boss is provided on the side of the leg tube plug 840 near the main crossbeam 200.
[0034] Of course, the support frame 1000 can also be designed in other structural forms, which are not limited here.
[0035] To enable the rapid unfolding or folding of the riser 400, support bracket 300, and / or foot tube 500, please refer to [link / reference needed]. Figures 1-3 In this embodiment, the support frame 1000 further includes a first connecting pipe 610 and a first sliding member 620. One end of the first connecting pipe 610 is connected to the vertical pipe 400, and the other end of the first connecting pipe 610 is connected to the first sliding member 620. The first sliding member 620 is movably connected to the main crossbeam 200. And / or, the support frame 1000 further includes a second sliding member 640 and a plurality of second connecting pipes 630. Each second connecting pipe 630 corresponds to a foot pipe 500. One end of each second connecting pipe 630 is connected to the corresponding foot pipe 500, and the other end of each second connecting pipe 630 is connected to the second sliding member 640. The second sliding member 640 is movably connected to the main crossbeam 200. The first sliding member 620 and / or the second sliding member 640 move along the main crossbeam 200 to quickly unfold or fold the vertical pipe 400 and / or the foot pipe 500.
[0036] In this embodiment, the first connecting pipe 610 is connected to the first sliding member 620 via fasteners such as rivets. The first sliding member 620 is sleeved on the main crossbeam 200 and can move along the main crossbeam 200. The second connecting pipe 630 is connected to the second sliding member 640 via fasteners such as rivets. The second sliding member 640 is sleeved on the main crossbeam 200 and can move along the main crossbeam 200. Alternatively, a guide rail structure can be provided on the main crossbeam 200, and the first sliding member 620 and the second sliding member 640 can be sliders that slide in conjunction with the guide rail. The movable connection between the first sliding member 620, the second sliding member 640, and the main crossbeam 200 can also be designed in other structural forms, which are not limited here.
[0037] To prevent the first sliding member 620 and / or the second sliding member 640 from moving relative to the main crossbeam 200 when the support frame 1000 is unfolded and in use, thereby causing some safety issues, in this embodiment, the first sliding member 620 is provided with a first locking member 621, which is configured to selectively lock or release the movement of the first sliding member 620 relative to the main crossbeam 200; and / or, the second sliding member 640 is provided with a second locking member 641, which is configured to selectively lock or release the movement of the second sliding member 640 relative to the main crossbeam 200.
[0038] Optionally, please refer to Figures 1-3 and combined Figure 4 and Figure 5 , Figure 5 This is an exploded view of the locking and sliding components provided in an embodiment of the present invention. The support frame 1000 in this embodiment also includes a toothed strip 700 disposed on the main crossbeam 200; the first locking component 621 is a lever, and the first locking component 621 has multiple toothed portions 6211 that mesh with the toothed strip 700; and / or, the second locking component 641 is a lever, and the second locking component 641 has multiple toothed portions 6211 that mesh with the toothed strip 700. Locking and fixing are achieved through gear meshing, which is convenient to operate, has strong locking ability, and a reliable structure. In this embodiment, the first sliding component 620 and the second sliding component 640 are connected to the lever through knurled pins or other connecting parts, relying on the meshing of the toothed portions 6211 on the lever with the toothed strip 700 to lock the first sliding component 620 and the second sliding component 640 onto the main crossbeam 200. When unlocking is required, open the latch to disengage the toothed part 6211 from the toothed bar 700, thereby unlocking. The first sliding member 620 and the second sliding member 640 can move relative to the main crossbeam 200.
[0039] Specifically, in this embodiment, the first locking member 621 is rotatably connected to the first sliding member 620. The first locking member 621 is provided with a plurality of toothed portions 6211 that mesh with the toothed bar 700. The first locking member 621 can rotate relative to the first sliding member 620 to allow the toothed portions 6211 to move closer to or away from the main crossbeam 200. When the first locking member 621 rotates in the locking direction, it drives the toothed portions 6211 to move closer to and finally press against the main crossbeam 200, causing the toothed portions 6211 to embed into the toothed grooves of the toothed bar 700, thereby restricting the movement of the first sliding member 620 relative to the main crossbeam 200 and locking its position on the main crossbeam 200. When the first locking member 621 rotates in the releasing direction, it drives the toothed portions 6211 away from the main crossbeam 200, causing the toothed portions 6211 to disengage from the toothed bar 700, thereby releasing the movement restriction on the first sliding member 620 and unlocking the device. In this embodiment, the second locking member 641 is also rotatably connected to the second sliding member 640. Its structure and location are the same as those of the first locking member 621 and the first sliding member 620 described above, and will not be repeated here.
[0040] Of course, the locking structure can also be designed in other structural forms, which are not limited here. For example, a limiting block can be set on the main crossbeam 200 to hold the first sliding member 620 and the second sliding member 640 when the support frame 1000 is unfolded and in use.
[0041] Please see Figure 4 In this embodiment, the second connecting pipe 630 is connected to the foot pipe 500 via a connecting rod sleeve 850. The connecting rod sleeve 850 is fitted onto the second connecting pipe 630 and connected to the foot pipe 500. To reduce friction between the connecting rod sleeve 850 and the foot pipe 500, a gasket 860 is provided between the connecting rod sleeve 850 and the foot pipe 500 in this embodiment. Optionally, the vertical pipe 400 is connected to the first connecting pipe 610 via a vertical pipe connector 870. The vertical pipe connector 870 is fitted onto the vertical pipe 400, and the first connecting pipe 610 is hinged to the vertical pipe connector 870.
[0042] The following is a detailed description of the support plug structure 100.
[0043] Figure 6 This is an exploded view of the support plug structure 100 provided in an embodiment of the present invention; Figure 7 This is an exploded view of the support plug structure 100, support bracket 300, and vertical tube 400 provided in the embodiments of this utility model. Figure 8 This is a cross-sectional schematic diagram of the first state of the support plug structure 100 provided in an embodiment of the present utility model. Figure 9 This is a cross-sectional schematic diagram of the support plug structure 100 in the second position provided in an embodiment of the present invention; Figure 10This is a cross-sectional view of the support plug structure 100 in the first position provided in the embodiment of the present invention, where the locking block 122 is in the first position.
[0044] Please see Figures 6-10 The support rod plug structure 100 provided in the embodiment of this utility model includes a fixing seat 110 and a support rod plug 120. The fixing seat 110 is used to connect and fix with the support rod bracket 300. A locking cavity 1111 is formed inside the fixing seat 110, and a relief groove 1112 communicating with the locking cavity 1111 is opened on the top of the fixing seat 110. The cross-sectional area of the relief groove 1112 is smaller than the cross-sectional area of the locking cavity 1111. The support rod plug 120 includes a connector 121 and a... The locking block 122 is connected to the connector 121, and a slot 123 is formed between the connector 121 and the locking block 122. The connector 121 is used to connect with the support rod accessory. The locking block 122 is configured to enter the locking cavity 1111 along the relief groove 1112 and rotate at a set angle within the locking cavity 1111, so that the slot 123 engages with the fixing seat 110, thereby locking the locking block 122 and the fixing seat 110. The locking block 122 can directly enter the locking cavity 1111 through the relief groove 1112, and locking can be achieved simply by rotation, without the need for tools or complicated operation steps. Similarly, it can be removed by rotating in the opposite direction to unlock, realizing quick installation and removal of the support rod plug 120, greatly improving the convenience and efficiency of use. The locking block 122 rotates to lock the rod plug 120 to the fixed base 110, effectively preventing the rod plug 120 from coming off the fixed base 110 due to accidental force or vibration, ensuring the reliability and stability of the connection. Furthermore, the cross-sectional area of the clearance groove 1112 is smaller than that of the locking cavity 1111, meaning that the locking block 122 can only be inserted or removed when aligned with the clearance groove 1112, effectively preventing accidental loosening due to accidental contact or shaking. The rod plug structure 100 is also simple.
[0045] Please see Figure 6 and Figure 7In this embodiment, the locking block 122 has an elliptical cross-sectional shape. When the locking block 122 is rotated to the first position, the slot 123 engages with the fixing seat 110, and the locking block 122 is locked to the fixing seat 110. When the locking block 122 is rotated to the second position, the locking block 122 is unlocked from the fixing seat 110, and the locking block 122 can be moved out along the relief slot 1112. The support rod plug 120 is inserted into the locking shell 111 from the relief slot 1112, and the support rod plug 120 is rotated until it cannot be rotated. At this time, the support rod plug 120 is in the locked state. In the locked state, the locking block 122 of the rod plug 120 is pressed by the inner wall of the locking cavity 1111 of the locking housing 111, and the slot 123 is engaged with the locking housing 111. At this time, the upper surface of the locking block 122 of the rod plug 120 is pressed by the top inner wall of the locking housing 111 in the vertical direction and subjected to downward pressure in the vertical direction. To unlock, the rod plug 120 is rotated in the opposite direction; the unlocking process is the reverse of the locking process.
[0046] Of course, the cross-sectional shape of the locking block 122 can also be designed to be other shapes, as long as the difference between its length and width is large. In order to facilitate the alignment and insertion of the locking block 122 into the relief groove 1112, the cross-sectional shape of the relief groove 1112 in this embodiment is the same as the cross-sectional shape of the locking block 122, and the cross-sectional area of the upper groove is slightly larger than or equal to the cross-sectional area of the locking block 122. Of course, the cross-sectional shape of the relief groove 1112 may not be the same as the cross-sectional shape of the locking block 122, which is not limited here.
[0047] Please see Figures 6-10 In this embodiment, the connector 121 is provided with a mounting structure for detachable connection with the support rod accessories. The support rod plug 120 itself serves as a standard connection platform. Through this unified mounting structure, various different support rod accessories, such as support rod forks, alarms, and lights, can be adapted. This greatly enhances the modularity of the product, allowing users to flexibly replace accessories as needed. Optionally, the mounting structure in this embodiment is an internally threaded hole 1211, which is used for threaded connection with the support rod accessory. Of course, the mounting structure can also be an externally threaded structure, that is, a thread is provided on the outside of the connector 121. The mounting structure can also be a snap-fit structure or other quick-installation structure that enables detachable connection, so as to quickly install, remove or replace different support rod accessories.
[0048] Please continue reading. Figures 6-10In this embodiment, the fixing base 110 includes a locking shell 111 and a bottom cover 112. The bottom cover 112 is inserted into the locking shell 111 and is detachably connected to the locking shell 111. The locking shell 111 has a locking cavity 1111 inside and a clearance groove 1112 on the top of the locking shell 111. The locking shell 111 has a first mounting hole 1113 and the bottom cover 112 has a second mounting hole 1121. The first mounting hole 1113 and the second mounting hole 1121 are coaxially arranged and used to jointly pass through the support rod bracket 300.
[0049] Optionally, in this embodiment, the locking shell 111 and the bottom cover 112 are also provided with threaded holes 1122. The axis of the threaded hole 1122 is perpendicular to the axis of the second mounting hole 1121. The threaded fastener 900 passes through the threaded hole 1122 to connect and fix the locking shell 111, the bottom cover 112, and the support rod bracket 300. To prevent the threaded fastener 900 from falling off after loosening, in this embodiment, the threaded hole 1122 of the bottom cover 112 communicates with the locking cavity 1111, but does not penetrate the side of the bottom cover 112 away from the relief groove 1112 of the locking shell 1111. The threaded fastener 900 enters the locking cavity 1111 from the relief groove 1112 and is then assembled at the threaded hole 1122. Of course, the threaded fastener 900 can also pass through from the side of the bottom cover 112 away from the relief groove 1112 to fix the bottom cover 112, the locking cover, and the support rod bracket 300. In this embodiment, the threaded fastener is a screw, but other threaded fasteners such as bolts can also be used, and this is not limited here. The bottom cover 112 and the fixing seat 110 can also be connected by other methods such as snap-fit, plug-in, or welding, and this is not limited here.
[0050] Alternatively, the mounting base 110 can be designed as an integral structure, or as other structural forms, as long as the support plug 120 and the support bracket 300 can be detachably connected.
[0051] The working principle of the support plug structure 100 provided in this embodiment is as follows: Insert the rod plug 120 into the locking housing 111 through the relief groove 1112, and rotate the rod plug 120 to the first position. At this time, the locking block 122 cannot be moved out of the relief groove 1112, and the slot 123 is held in place by the fixing seat 110. The upper surface of the rod plug 120 and the locking block 122 is squeezed by the inner wall of the top of the locking housing 111 in the vertical direction and is subjected to downward pressure in the vertical direction. The rod plug 120 is locked in the fixing seat 110. To unlock, rotate the rod plug 120 in the opposite direction so that the locking block 122 is aligned with the relief groove 1112, so that the locking block 122 can be moved out of the locking cavity 1111 along the relief groove 1112 and disengaged from the fixing seat 110.
[0052] In summary, the support rod plug structure 100 includes a fixing seat 110 and a support rod plug 120. The fixing seat 110 is used to connect and fix with the support rod bracket 300. A locking cavity 1111 is formed inside the fixing seat 110, and a relief groove 1112 communicating with the locking cavity 1111 is opened on the top of the fixing seat 110. The cross-sectional area of the relief groove 1112 is smaller than the cross-sectional area of the locking cavity 1111. The support rod plug 120 includes a connector 121 and a locking block 1. 22. The connector 121 and the locking block 122 are connected, and a groove 123 is formed between the connector 121 and the locking block 122. The connector 121 is used to connect with the support rod accessory. The locking block 122 is configured to enter the locking cavity 1111 along the relief groove 1112 and rotate at a set angle within the locking cavity 1111, so that the groove 123 engages with the fixing seat 110, thereby locking the locking block 122 and the fixing seat 110. The locking block 122 can directly enter the locking cavity 1111 through the relief groove 1112, and locking can be achieved simply by rotation, without the need for tools or complicated operating steps. Similarly, it can be removed by rotating in the opposite direction when unlocking, realizing quick installation and removal of the support rod plug 120, greatly improving the convenience and efficiency of use. The locking block 122 rotates to lock the rod plug 120 to the fixed base 110, effectively preventing the rod plug 120 from coming off the fixed base 110 due to accidental force or vibration, ensuring the reliability and stability of the connection. Furthermore, the cross-sectional area of the clearance groove 1112 is smaller than that of the locking cavity 1111, meaning that the locking block 122 can only be inserted or removed when aligned with the clearance groove 1112, effectively preventing accidental loosening due to accidental contact or shaking. The rod plug structure 100 is also simple.
