Description

Technical Field

[0001] The present invention relates to the field of fishing platforms, in particular to a quick-release connection structure and a fishing platform. Background Art

[0002] Since fishing enthusiasts need to find a flat position to set up their rods when fishing, and the shore environment near wild natural waters is often complex and uneven, in order to obtain a comfortable fishing position and to facilitate the placement of other equipment such as fishing boxes, fishing enthusiasts generally use fishing platforms to temporarily build a position to set up their rods. Existing fishing platforms generally consist of a table body and supporting columns. In order to improve the supporting effect, supporting columns are respectively set at the four corners or multiple corners of the table body. In order to facilitate carrying, the columns and the table are fixed to the table by clamps and fastening screws. When not in use, the columns can be removed. Furthermore, foldable fishing platforms have also appeared on the market, which make the table into two parts that can be interlocked, the first table and the second table. The inner sides of the surfaces are all hollow, and the first and second surfaces are connected by a hinge mechanism. When in use, the first and second surfaces are unfolded to form a fishing platform. After use, the two surfaces are buckled together, and accessories such as supporting columns are placed in the formed cavity for easy transportation, carrying and storage. Since the thickness of the table is thinner than before, this structure requires the use of high-strength materials to meet the load requirements of anglers and equipment such as fishing boxes placed on the table at the same time. On the other hand, the table must be flat after unfolding to avoid the sides of the table being warped and the center being concave, which causes the table to be unstable and fall or slide. At this stage, ordinary hinged connection structures cannot guarantee the flatness of the unfolded table, and there are certain safety hazards.

[0003] As disclosed in Chinese utility model CN210929251U, the new foldable fishing platform is provided with a table top, the four corners of which are connected to supporting columns, the table top is composed of a first table top and a second table top hingedly connected, and a matching snap-in structure is provided at the connection between the first table top and the second table top, the snap-in structure includes a horizontal extension part and an inner recessed part that can be interlocked, the horizontal extension part and the inner recessed part are respectively arranged on the side edges where the first table top and the second table top are hingedly connected, after the horizontal extension part is embedded in the inner recessed part, the horizontal extension part is flush with the surface height of the table top, this technical solution forms a complete table top by hingedly connecting the first table top and the second table top, which is consistent with the existing folding method, however, although this folding method reduces the storage space, it takes a long time to disassemble, and the supporting columns cannot be folded together, which is not convenient enough. Therefore, there is a need for a fishing platform with the characteristics of simple structure, easy installation, stable structure, and lighter weight. Summary of the Invention

[0017] 3. Beneficial Effects

[0018] Compared with the prior art, the present invention controls the movable connecting rod through the table folding connecting piece, so that the movable connecting rod can move relative to the fixed connecting rod until the second support frame overlaps under the first support frame, and then the first support frame and the second support frame are folded inward, and the telescopic support legs are folded in the gap left between the first support frame and the second support frame under the control of the leg folding connecting piece, thereby realizing the rapid disassembly of the fishing platform, reducing storage space, improving installation and disassembly efficiency, and ensuring structural stability.

[0042] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0043] Example 1:

[0044] See also Figures 1-13As shown, a quick-release connection structure is provided on a fishing platform, which includes a middle pillar 1. A pair of first support frames 2 and a pair of second support frames 3 are symmetrically provided on both sides of the middle pillar 1. Each of the first support frames 2 and the second support frames 3 is provided with a support platform 21. A telescopic support leg 22 is vertically provided at the outer corner of each first support frame 2 and the second support frame 3. The quick-release connection structure includes a fixed connecting rod 4 and a movable connecting rod 5. The fixed connecting rod 4 and the movable connecting rod 5 are symmetrically provided on both sides of the middle pillar 1. The length directions of the fixed connecting rod 4 and the movable connecting rod 5 are perpendicular to the middle pillar. 1, the end of the fixed connecting rod 4 is fixedly connected to the upper end of the middle pillar 1, the end of the movable connecting rod 5 is movably connected to the upper end of the middle pillar 1, the movable connecting rod 5 can move vertically and rotate horizontally relative to the fixed connecting rod 4, a pair of first support frames 2 are symmetrical and rotatably arranged on both sides of the fixed connecting rod 4, a pair of second support frames 3 are symmetrical and rotatably arranged on both sides of the movable connecting rod 5, the upper half of the middle pillar 1 is provided with a table folding connector 6 connected to the movable connecting rod 5, and a leg folding connector 7 is connected between each telescopic supporting leg 22 and the corresponding first supporting frame 2 and second supporting frame 3.

[0045] During the assembly of the fishing platform, the supporting platforms 21 of the pair of first supporting frames 2 and the supporting platforms 21 of the pair of second supporting frames 3 are spliced ​​to form a complete table top, the middle pillar 1 is supported on the ground, and the table top is supported by adjusting the height of the telescopic supporting legs 22 to keep the table top level and achieve a stable support effect;

[0046] When the fishing platform is disassembled, the user operates the table folding connector 6 to release the fixed state of the movable connecting rod 5. Then, the user moves the movable connecting rod 5 relative to the fixed connecting rod 4 until the movable connecting rod 5 moves along the middle pillar 1 to the bottom of the fixed connecting rod 4. The user operates the leg folding connector 7 to make the telescopic support legs 22 fold on the lower surface along the diagonal of the support platform 21. All telescopic support legs 22 are folded. Then the user rotates the movable connecting rod 5 180° around the middle pillar 1, causing the second support frame 3 to overlap directly below the first support frame 2. At this time, the pair of first support frames 2 and the pair of second support frames 3 are still in a flat state. The user first folds the pair of second support frames 3 inward, and then folds the pair of first support frames 2 inward. The second support frame 3 is between the pair of first support frames 2, and each first support frame 2 and second support frame 3 are in a horizontal state. There is space for the telescopic support legs 22 to fold between the pair of second support frames 3, and between the first support frame 2 and the corresponding second support frame 3.

[0047] See also Figure 2-Figure 10As shown, both ends of the fixed connecting rod 4 extend vertically outward to provide a first extension bar 41, and both ends of the movable connecting rod 5 extend vertically outward to provide a second extension bar 51, the first support frame 2 is axially connected between the two first extension bars 41, and the second support frame 3 is axially connected between the two second extension bars 51, each first extension bar 41 is provided with a first axis connecting rod 411 for rotationally connecting to the corresponding first support frame 2, and each second extension bar 51 is provided with a second axis connecting rod 511 for rotationally connecting to the corresponding second support frame 3, the length of the first extension bar 41 is longer than the length of the second extension bar 51, and the installation position of each first axis connecting rod 411 and each second axis connecting rod 511 is respectively close to the outer end of the corresponding first extension bar 41 and the second extension bar 51, and the distance between the two first axis connecting rods 411 is longer than the distance between the two second axis connecting rods 511.

[0048] When the first support frame 2 and the second support frame 3 are in a spliced ​​state, the support platform 21 of the first support frame 2 and the support platform 21 of the second support frame 3 are combined to form a complete table top. As the first support frame 2 and the second support frame 3 are in an overlapping state, the second support frame 3 is rotated around the axis of the second axial connecting rod 511 until the pair of second support frames 3 are parallel to each other. Then, the first support frame 2 is rotated around the axis of the first axial connecting rod 411 until the pair of first support frames 2 are parallel to each other. The pair of second support frames 3 are in a state of being sandwiched between the pair of first support frames 2, which reduces storage space and improves portability.

[0049] See also Figure 2-Figure 10 As shown, a protrusion 11 is extended from the upper end of the middle pillar 1 toward the fixed connecting rod 4 and the movable connecting rod 5. The ends of the fixed connecting rod 4 and the movable connecting rod 5 are provided with a card slot from top to bottom that is clamped on the corresponding protrusion 11. The table folding connecting piece 6 is provided with a fixed block 61 and a movable sleeve 62. The fixed block 61 is a semi-arc block. The fixed block 61 is fixedly connected to the upper half of the middle pillar 1 and the surface of the fixed block 61 is in contact with the fixed connecting rod 4. The fixed connecting rod 4 is located between the protrusion 11 and the fixed block 61. The movable sleeve 62 is coaxially sleeved on the middle pillar 1. The movable sleeve 62 is located below the fixed block 61. The movable sleeve 62 is fixedly connected to the movable connecting rod 5. When the upper end of the movable sleeve 62 is in contact with the lower surface of the fixed block 61, the first support frame 2 and the second support frame 3 are in a flush state.

[0050] When the fixed first support frame 2 and the second support frame 3 are in a spliced ​​state, the first support frame 2 and the second support frame 3 are evenly unfolded, and the fixed connecting rod 4 and the movable connecting rod 5 are engaged with the protrusion 11 at the upper end of the middle pillar 1 through the slot, and then the fixed block 61 is fixed to the upper half of the middle pillar 1 and supports the fixed connecting rod 4, so that the fixed connecting rod 4 cannot move, and the movable connecting rod 5 is supported by the movable sleeve 62, and the movable sleeve 62 and the middle pillar 1 are fixed by the table folding connector 6. After the movable sleeve 62 is released from the fixed state, the movable sleeve 62 moves down along the middle pillar 1, and the movable connecting rod 5 also moves relative to the fixed connecting rod 4, so that the second support frame 3 can overlap with the first support frame 2, which is convenient for quick disassembly.

[0051] See also Figure 2-Figure 10 As shown, the table folding connector 6 is also provided with a support ring sleeve 621, which is coaxially sleeved on the middle pillar 1, and the support ring sleeve 621 is located below the movable sleeve 62. A socket perpendicular to the axial direction of the middle pillar 1 is opened on the support ring sleeve 621 along the direction of its axis, and a pin 622 is inserted into the socket. The upper half of the middle pillar 1 is provided with an upper pin hole 12 and a lower pin hole 13 for the pin 622 to pass through from top to bottom. When the pin 622 passes through the upper pin hole 12 to fix the support ring sleeve 621, the movable sleeve 62 and the fixed block 61 are in a contact state. When the pin 622 passes through the lower pin hole 13 to fix the support ring sleeve 621, the second support frame 3 is below the first support frame 2 and is able to rotate.

[0052] When the position of the movable sleeve 62 on the middle pillar 1 is controlled, the support ring sleeve 621 is positioned on the middle pillar 1 through the pin 622. When the pin 622 passes through the support ring sleeve 621 and is inserted into the upper pin hole 12, the support ring sleeve 621 supports the movable connecting rod 5 so that the second support frame 3 and the first support frame 2 are in a spliced ​​state. When the pin 622 passes through the support ring sleeve 621 and is inserted into the lower pin hole 13, the second support frame 3 is decomposed below the first support frame 2. By adjusting the position of the support ring sleeve 621, the installation state between the second support frame 3 and the first support frame 2 is controlled.

[0053] See also Figure 2-Figure 10As shown, the inner side of the first support frame 2 is provided with a first limit rod 42 extending from the outside to the inside and contacting the end of the corresponding first extension bar 41, and the inner side of the second support frame 3 is provided with a second limit rod 52 extending from the outside to the inside and contacting the end of the corresponding second extension bar 51. The ends of the first extension bar 41 and the second extension bar 51 both have chamfers inclined inward from top to bottom, and the ends of the first limit rod 42 and the second limit rod 52 respectively fit in with the chamfers of the ends of the corresponding first extension bar 41 and the second extension bar 51. The outer ends of the fixed connecting rod 4 and the movable connecting rod 5 are both provided with a sliding groove 512 inward, and a card strip 5121 with both ends extending outward is provided for sliding in the sliding groove 512.

[0054] When the connection between the first support frame 2 and the second support frame 3 is completed, the clamping strip 5121 on the fixed connecting rod 4 and the movable connecting rod 5 is moved inward from the outer end along the corresponding slide groove 512, causing the clamping strip 5121 to press the first support frame 2 and the second support frame 3 against the first extension strip 41 and the second extension strip 51, limiting the movement of the first support frame 2 and the second support frame 3, and avoiding the first support frame 2 and the second support frame 3 from swinging down and collapsing when under pressure. The contact between the first limiting rod 42 and the first extension strip 41 on the first support frame 2, and the contact between the second limiting rod 52 and the second extension strip 51 on the second support frame 3, prevent the first support frame 2 and the second support frame 3 from flipping up, thereby achieving the effect of stabilizing the spliced ​​table top.

[0055] See also Figure 2 、 Figure 11 、 Figure 12 and Figure 13 As shown, a support block 71 is fixedly provided at the outer corner of the first support frame 2 and the second support frame 3. A first through-hole 711 is vertically and through-opened on the support block 71 for the telescopic support leg 22 to pass through. A second through-hole 712 is opened inwardly on the side of the support block 71 and is connected to the first through-hole 711. The axial direction of the first through-hole 711 is perpendicular to the axial direction of the second through-hole 712. A threaded extrusion rod 7121 is threadedly connected in the second through-hole 712 for fixing the telescopic support leg 22 by extrusion.

[0056] When the telescopic support leg 22 adjusts the support height, the telescopic support leg 22 is moved along the first through-hole 711 on the support block 71 until it is adjusted to a suitable height, and then the threaded extrusion rod 7121 is screwed into the first through-hole 711 along the second through-hole 712, causing the threaded extrusion rod 7121 to squeeze the telescopic support leg 22, thereby achieving the effect of fixing the telescopic support leg 22.

[0057] See also Figure 2 、 Figure 11 、 Figure 12 and Figure 13As shown, the leg folding connecting member 7 is provided with a shaft rod 72, and both sides of the lower end of the support block 71 have a shaft connection portion 713. The shaft rod 72 is rotatably connected between the two shaft connections 713. The axial direction of the shaft rod 72 is perpendicular to the diagonal direction from the inside to the outside of the corresponding first support frame 2 or the second support frame 3. The upper half of the telescopic support leg 22 is provided with a strip opening 221 along its axial direction, which is sleeved on the shaft rod 72. When the threaded extrusion rod 7121 releases the fixed state of the telescopic support leg 22, the telescopic support leg 22 is in a state where it can swing around the axis of the shaft rod 72.

[0058] When folding the telescopic support leg 22, first screw the threaded extrusion rod 7121 outward to release the fixed state of the telescopic support leg 22, then move the telescopic support leg 22 downward along the shaft 72 until the upper end of the telescopic support leg 22 is disengaged from the first through-hole 711 on the support block 71, then rotate the telescopic support leg 22 90°, adjusting it from a vertical state to a horizontal state, keeping the telescopic support leg 22 flush with the support platform 21, and finally folding the telescopic support leg 22 along the diagonal of the support platform 21 at the bottom of the support platform 21.

[0059] See also Figure 2 、 Figure 11 、 Figure 12 and Figure 13 As shown, an elastic sleeve 73 is provided on the inner side of the lower end of the support block 71 for fixing the telescopic support leg 22 in a clamping manner flush with the support platform 21.

[0060] When the telescopic support leg 22 is folded, the telescopic support leg 22 is clamped in the elastic jacket 73 , and the elastic jacket 73 is clamped in the strip opening 221 on the telescopic support leg 22 to prevent it from falling.

[0061] See also Figure 2 、 Figure 11 and Figure 12 As shown, the surface of the support platform 21 is a non-slip surface 211 , and a spring 212 is provided between each support platform 21 and the corresponding first support frame 2 and second support frame 3 .

[0062] When the user is on the support platform 21, since springs 212 are connected between the support platform 21 and the corresponding first support frame 2 and second support frame 3, the effects of buffering and shock absorption are achieved, and the impact and vibration of the fishing platform can be absorbed. This can provide a more stable and comfortable fishing environment for anglers on the fishing platform.

[0063] Example 2:

[0064] A fishing platform disclosed in this embodiment includes a middle pillar 1, a pair of first support frames 2 and a pair of second support frames 3. Each of the first support frames 2 and the second support frames 3 is provided with a support platform 21. A telescopic support leg 22 is vertically provided at the outer corner of each of the first support frame 2 and the second support frame 3. It also includes a quick-release connection structure, which includes a fixed connecting rod 4 and a movable connecting rod 5. The fixed connecting rod 4 and the movable connecting rod 5 are symmetrically arranged on both sides of the middle pillar 1.

[0065] The present invention controls the movable connecting rod 5 through the table folding connecting member 6, so that the movable connecting rod 5 can move relative to the fixed connecting rod 4 until the second support frame 3 overlaps under the first support frame 2, and then the first support frame 2 and the second support frame 3 are folded inward, and the telescopic support legs 22 are folded in the gap between the first support frame 2 and the second support frame 3 under the control of the leg folding connecting member 7, thereby reducing storage space, improving installation and disassembly efficiency, and ensuring structural stability.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
