Description

Technical Field

[0001] This utility model relates to the field of tripod technology, specifically to a retractable connection structure and a tripod. Background Technology

[0002] A tripod is a support device with three legs; its core function is to provide a stable platform for cameras, mobile phones, lights, or other equipment to eliminate shaking during operation and obtain clear, high-quality images.

[0003] Chinese patent document CN210196910U discloses a portable tripod, including a support base. The support base is movably connected to an upper bracket via a pin. An outer tube is fixedly inserted into both ends of the upper bracket. A lower connecting bracket is fixedly installed at the lower end of the outer tube. A central shaft is fixedly installed in the middle of the inner side of the lower connecting bracket. A second pull rod is movably sleeved in the middle of the central shaft. A first pull rod is movably sleeved in the inner end of the second pull rod. The upper connecting bracket is movably sleeved on the outer tube. An inner tube is fixedly installed into both ends of the upper connecting bracket. A lower bracket is fixedly installed at the lower end of the inner tube. A middle tube is movably inserted into the middle of the lower bracket. A guide block is fixedly installed at the upper end of the middle tube. A foot ball joint is connected to the lower end of the middle tube via a foot connecting ball.

[0004] In order to increase the stability of the tripod when using the above technical solution, the limiting nut can be screwed inward to increase the friction between the first and second pull rods by pressing against the limiting plate. This allows the positions of the first and second pull rods to be relatively fixed when the tripod is in use. When storing and carrying the tripod, the first and second levers are opened, and the limiting nut on the limiting bolt is rotated and moved outward. At this time, the upper bracket is manually rotated inward and the upper connecting bracket 4 is slid to reduce the distance between the inner and outer tubes. The second pull rod is inserted into the first pull rod, and the magnetic attraction of the small magnet causes each pair of lower connecting brackets to stick together.

[0005] The advantages of the above technical solution are that it is easy to store and fold, the folding operation is simple and convenient, it is flexible in use, and it is inexpensive, providing convenience for use and transportation. However, the structure of the above technical solution is relatively complex, and the use and storage process requires rotating the limiting nut to lock or unlock the first and second pull rods, which not only affects the operating efficiency but also causes inconvenience to the user.

[0040] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example 1

[0041] This embodiment provides a retractable connection structure, such as Figure 1-4 As shown, the tripod includes: a first connecting plate 1, a first connecting member 11, and a second connecting member 12; wherein, there are at least three first connecting plates 1; there are at least three first connecting members 11, including a first connecting blade 21 and a second connecting blade 22 rotatably mounted on one side of the first connecting blade 21; the first connecting blade 21 is adapted to be fixedly mounted on the inner side of the tripod support rod 91 near the bottom, and the second connecting blade 22 is fixedly mounted on one end of the first connecting plate 1; there are at least three second connecting members 12, including a third connecting blade 23 and a fourth connecting blade 24 rotatably mounted on one side of the third connecting blade 23; the third connecting blade 23 is fixedly mounted on the other end of the first connecting plate 1; the three fourth connecting blades 24 are stacked and connected to each other, such that any two adjacent rotation axes of the three second connecting members 12 form a 60° angle, thereby enabling the three first connecting plates 1 to be retracted and extended synchronously.

[0042] When using a tripod equipped with the retractable connection structure of this embodiment, the unfolding operation is very convenient: simply open the support rod 91 by hand, and the three first connecting plates 1 will unfold simultaneously, providing stable support for the tripod; when it is necessary to store the tripod, simply lift any one of the first connecting plates 1 upwards by hand or foot, and the three first connecting plates 1 will retract simultaneously, causing the support rod 91 to fold and store (or lift any one of the first connecting plates 1 with your foot and push the support rod 91 inwards by hand), thus completing the storage of the tripod. Compared with the complex structure of traditional tripods, which require turning the limit nut to lock or unlock the first and second pull rods for use and storage, the retractable connection structure of this embodiment is simple in design, requiring only simple operation when unfolding or storing, effectively improving the convenience of use and work efficiency.

[0043] The fourth connecting blade 24 has at least two fourth connecting through holes 44. After the three fourth connecting blades 24 are stacked together, the fourth connecting through holes 44 on the two fourth connecting blades 24 in the stacked position are vertically opposite each other. A fixing rivet 45 is used to pass through the vertically opposite fourth connecting through holes 44 to fix the two fourth connecting blades 24 in the stacked position. The specific connection method of the fixing rivet 45 is as follows: the end of the fixing rivet 45 extends from the other end of the fourth connecting through hole 44. A riveting tool is used to apply pressure to the extended end of the rivet, causing it to undergo plastic deformation and expand outward, forming a riveting head that is tightly pressed against the surface of the fourth connecting blade 24. This process causes the original head of the rivet and the newly formed riveting head to press the blade tightly from both sides, thereby achieving a complete fixed connection.

[0044] The third connecting blade 23 has at least two third connecting through holes 56; the other end of the first connecting plate 1 has at least two third threaded holes 58; after the third connecting bolt 57 passes through the third connecting through holes 56, it is screwed into the third threaded holes 58, thereby fixing the third connecting blade 23 to the other end of the first connecting plate 1.

[0045] like Figure 3-4As shown, the first connecting blade 21 and the second connecting blade 22 are rotatably mounted together via a first rotating connection structure. The first rotating connection structure includes a first connecting cylinder 31, a second connecting cylinder 32, and a first connecting shaft 41. At least one first connecting cylinder 31 is provided, which is hollow and open at both ends, and is formed on one side of the first connecting blade 21. At least one second connecting cylinder 32 is provided, which is hollow and open at both ends, and is formed on one side of the second connecting blade 22. The first connecting shaft 41 passes through the first connecting cylinder 31 and the second connecting cylinder 32, thereby rotatably mounting the first connecting blade 21 and the second connecting blade 22 together. After the first connecting shaft 41 is inserted, shaft caps are installed at both ends to achieve axial positioning. The third connecting blade 23 and the fourth connecting blade 24 are rotatably mounted together via a second rotating connection structure. This second rotating connection structure includes a third connecting cylinder 33, a fourth connecting cylinder 34, and a second connecting shaft 42. At least one third connecting cylinder 33 is provided, which is hollow and open at both ends, and is formed on one side of the third connecting blade 23. At least one fourth connecting cylinder 34 is provided, which is hollow and open at both ends, and is formed on one side of the fourth connecting blade 24. The second connecting shaft 42 passes through the third connecting cylinder 33 and the fourth connecting cylinder 34, thereby rotatably mounting the third connecting blade 23 and the fourth connecting blade 24 together. After the second connecting shaft 42 is inserted, shaft caps are installed at both ends to achieve axial positioning.

[0046] The first connecting blade 21 has at least two first connecting through holes 5; after passing through the first connecting through holes 5, the first connecting bolt 51 is screwed into the first threaded hole 52 of the support rod 91, thereby fixing the first connecting blade 21 onto the support rod 91; the second connecting blade 22 has at least two second connecting through holes 53; after passing through the second connecting through holes 53, the second connecting bolt 54 is screwed into the second threaded hole 55 at one end of the first connecting plate 1, thereby fixing the second connecting blade 22 onto one end of the first connecting plate 1.

[0048] When using a tripod equipped with the retractable connection structure of this embodiment, simply open the support rod 91 by hand, and the three second connecting plates 2 will unfold simultaneously, providing stable support for the tripod. When it is necessary to store the tripod, lift any second connecting plate 2 upwards by hand or foot, and all three second connecting plates 2 will retract simultaneously, causing the support rod 91 to fold and store (or lift any second connecting plate 2 with your foot and push the support rod 91 inwards by hand), thereby completing the storage of the tripod. The retractable connection structure of this embodiment is simple in design, requiring only simple operation when unfolding or storing, effectively improving ease of use and work efficiency.

After the fourth connecting shaft 75 is inserted, shaft caps are installed at both ends to achieve axial positioning.

[0051] The fifth connecting blade 61 has at least two fifth connecting through holes 8; a fifth connecting bolt 81 passes through the fifth connecting through holes 8 and is screwed into the fifth threaded hole 82 of the support rod 91, thereby fixing the fifth connecting blade 61 onto the support rod 91; the sixth connecting blade 62 has at least two sixth connecting through holes 83; a sixth connecting bolt 84 passes through the sixth connecting through holes 83 and is screwed into the sixth threaded hole 85 at one end of the second connecting plate 2, thereby fixing the sixth connecting blade 61 onto one end of the second connecting plate 2; the seventh connecting blade 63 has at least two seventh connecting through holes 86; a seventh connecting bolt 87 passes through the seventh connecting through holes 86 and is screwed into the seventh threaded hole 88 at the other end of the second connecting plate 2, thereby fixing the seventh connecting blade 63 onto the other end of the second connecting plate 2.
