[0002] A tripod is a common support device widely used in photography, videography, and observation. It consists of three extendable legs and a top support platform, providing stable support for equipment such as cameras and binoculars. Tripods are designed to provide a stable support point, helping users obtain clear and stable images during long exposures, in low-light conditions, or when precise composition is required. Different types of tripods have different functional characteristics, such as materials (e.g., aluminum alloy, carbon fiber), weight, height adjustment range, and portability, to meet the needs of professional photographers, amateurs, or specific application scenarios.

[0003] The existing tripod technology has the following shortcomings: Since most tripods are two-stage adjustable, they have two locking mechanisms. However, these two locking mechanisms are not related and each needs to be operated separately, which brings inconvenience to use. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-7The tripod linkage quick-lock structure of this utility model includes a support base and an upper fork 6 rotatably connected to the support base. To improve stability, the upper fork 6 is provided with three parts. The bottom end of the upper fork 6 is fixed with an outer tube 5 and an outer tube 28. One end of the outer tube 5 and the outer tube 28 is fitted with an upper locking slide 4, which can slide on the outer tube 5 and the outer tube 28. The upper locking slide 4 is elastically slidably connected to an upper locking clamp 9 along its thickness direction. More specifically, the upper locking slide 4 is provided with a spring 7 that abuts against the upper locking clamp 9. It also includes a rotating hinge 2, one end of which is provided with a screw. The other end of the swivel joint 2 (female 10) passes through the upper locking plate 9 and the upper locking slide 4. The nut 10 has a large cross-sectional area to prevent the swivel joint 2 from detaching from the upper locking slide 4, and also makes it easier to disassemble and assemble. The other end of the swivel joint 2 is rotatably connected to the locking lever 1 via the pin 3. The distance between the side and top surfaces of the locking lever 1 and the pin 3 is different, so the distance between the pin 3 and the upper locking slide 4 can be controlled by rotating the locking lever 1. Under the action of the swivel joint 2 and the nut 10, the upper locking plate 9 is controlled to move. When locked, the two sides of the upper locking plate 9 contact the outer tube 1 5 and the outer tube 2 28, respectively.

[0032] The upper locking clamp 9 is fixedly connected to the upper locking pressure block 11, and the upper locking slide 4 is elastically slidably connected to the upper locking pull block 12 along its height direction. More specifically, the upper locking pull block 12 is slidably installed in the upper locking slide 4 in the vertical direction, and a spring 8 for resetting the upper locking pressure block 11 is installed in the upper locking slide 4.

[0033] The upper locking pull block 12 is fixed with one end of the locking pull rod 13. The upper locking pressure block 11 and the upper locking pull block 12 have mutually cooperating inclined surfaces, as shown in the figure. When the upper locking clamping plate 9 and the upper locking pressure block 11 move, due to the mutually cooperating inclined surfaces of the upper locking pressure block 11 and the upper locking pull block 12, as shown in the figure, when the upper locking pressure block 11 moves closer to the upper locking pull block 12, the upper locking pull block 12 and the pull rod both move upward under the cooperation of the inclined surfaces of the upper locking pressure block 11 and the upper locking pull block 12.

[0034] The other ends of the outer tube 1 5 and the outer tube 2 28 are fixed with a fixed frame 17. The upper locking slide 4 is fixed with one end of two adjusting tubes 15. The two adjusting tubes 15 are slidably connected to the fixed frame 17. The other ends of the two adjusting tubes 15 are fixedly connected to the lower locking slide 18. The lower locking slide 18 is slidably connected to the adjusting tube 2 16. The bottom end of the adjusting tube 2 16 is provided with a support mechanism. More specifically, the support mechanism includes a support foot 20 and a foot nail 27. The sliding of the two adjusting tubes 15, the upper locking slide 4 and other components relative to the outer tube 1 5 and the outer tube 2 28 is the first-level adjustment. The sliding of the adjusting tube 2 16, the lower locking slide 18 and other components relative to the fixed frame 17 is the second-level adjustment. This increases the adjustment range of the tripod. The stability of the device is improved by the support foot 20 and the foot nail 27.

[0035] The locking rod 13 is elastically slidably connected to the driving block 25. More specifically, the locking rod 13 is located inside one of the adjusting tubes, which is more aesthetically pleasing. One of the locking rods 13 is fixed with a first blocking member 21 and a second blocking member 26. The driving block 25 is fitted with the locking rod 13, and the locking rail is fitted with an elastic member 22, which is a spring. The two ends of the elastic member 22 are in contact with the first blocking member 21 and the driving block 25, respectively. The lower locking slide 18 is slidably connected to a pressing block 24 for locking the second adjusting tube 16. There are two pressing blocks 24. The driving block 25 and the pressing block 24 have mutually cooperating inclined surfaces. When the locking rod 13 moves upward, it drives the driving block 25 and other components to move upward. Since the driving block 25 and the pressing block 24 have mutually cooperating inclined surfaces, as shown in the figure, the upward-moving driving block 25 causes the pressing block 24 to move closer to the second adjusting tube 16 and press the second adjusting tube 16, thus playing a fixing role.

[0036] Furthermore, the present invention is improved in that a blocking plate 19 is fixed at the bottom end of the lower locking slide 18, and the blocking plate 19 serves to seal.

[0037] Furthermore, the present invention is improved by having a slider 14 slidably connected to the two adjusting tubes 15, and the slider 14 is connected to the top of the adjusting tube 16, thereby improving the stability of the adjusting tubes 15 and other components when sliding.

[0038] Furthermore, the present invention is improved in that both ends of the fixing frame 17 are equipped with magnets 23, as shown in the figure. When the tripod is brought together, the adjacent magnets 23 are attached together to fix it.

[0039] The principle of this utility model is as follows: First, open the upper fork 6 and rotate the locking lever 1 to disengage the upper locking clamp 9 from the outer tube 1 5 and the outer tube 2 28. At this time, the drive block 25 and the pressing block 24 have a loosely fitted inclined surface, and the pressing block 24 exerts little force on the adjusting tube 2 16. Adjust the position of the adjusting tube 1 15 and the adjusting tube 2 16. After the adjustment is completed, rotate the locking lever 1 to move the upper locking clamp 9 towards the outer tube 1 5 and the outer tube 2 28. At the same time, the upper locking pressing block 11 squeezes the upper locking pull block 12, causing the upper locking pull block 12, the pull rod and the drive block 25 to move upward. The upward movement of the drive block 25 causes the pressing block 24 to move closer to the adjusting tube 2 16 and press the adjusting tube 2 16 tightly. In summary, this achieves a two-stage locking effect.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
